Maintenance measures of guide rail hydraulic lifting platform: For mechanized construction enterprises， whether the technical condition of construction machinery is good or not is a direct factor for the normal production of the enterprise. As far as construction machinery with hydraulic transmission is concerned

Maintenance measures of guide rail hydraulic lifting platform: For mechanized construction enterprises， the normal operation of the hydraulic system is a major sign of its good technical condition. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system， and correct maintenance is the foundation for the reliable operation of the hydraulic system. According to the work practice， a rough discussion is made on the maintenance of the construction machinery hydraulic system in the general working environment.

8I believe that many people want to know about the maintenance of the guide rail hydraulic lifting platform， because it is related to its service life. During use，Domestic elevator always check the connection of each part. If it is loose，Huicen3-meter hydraulic lifting platformQuality inspection it should be tightened. When the body is under pressure， check the tightness of the connecting bolts of the body (the pressure-causing state that can be used). All connecting shafts should have cotter pins and should be fully open.

iFrisinAlways use a tool bag when working at heights. The larger tools of the boarding bridge should be tied to the firm components with ropes， so as to prevent accidents caused by falling from high altitude.

The installer should confirm and count the details of the equipment， confirm that there are no omissions in the details of the delivered equipment， check whether the tools are complete， and ensure the smooth progress of the installation process.

PsausageThe piston of the hydraulic cylinder moves downward (that is， the weight falls). The hydraulic oil enters the upper end of the hydraulic cylinder through the anti-type electromagnetic reversing valve， and the oil returned from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve， hydraulic control check valve，Domestic elevator throttle valve， and isolating electromagnetic reversing valve. In order to make the weight drop smoothly and the brake safe and reliable a balance valve is installed on the oil return line to balance the circuit and maintain pressure so that the descending speed is not affected by the weight， and the flow rate and lifting speed are adjusted by the throttle valve. In order to make the brake safe and reliable， and prevent accidents， a hydraulic control check valve is added， the maintenance personnel should be notified immediately for maintenance. If any danger or possible mechanical accident is found a hydraulicCan lock itself safely. An overload sound-activated alarm is installed to distinguish overload or equipment failure.

LxWhen the hydraulic elevator breaks down or works abnormally， stop the machine immediately， cut off the main power supply of the machine room， and report to the management department for maintenance and detailed inspection.

Preventing solid impurities from entering the hydraulic system Clean hydraulic oil is the life of the hydraulic system. There are many precision couples in the hydraulic system， some have small damping holes，Domestic elevator some have gaps， etc. If solid impurities invade，Huicen3-meter hydraulic lifting platformQuality inspection it will cause straining of precision coupling parts， pinning blockage of oil passages， etc.， endangering the safe operation of the hydraulic system. Generally， the ways for solid impurities to invade the hydraulic system are: unclean hydraulic oil; unclean refueling tools; careless refueling and maintenance; The intrusion of solid impurities into the system can be prevented from the following aspects: when refueling， the hydraulic oil must be filtered and refilled， and the refueling tools should be reliable and clean. The filter at the filling port of the fuel tank cannot be removed in order to increase the fueling speed. Refueling personnel should use clean gloves and overalls to prevent solid impurities and fiber impurities from falling into the oil.

The capacity should be considered. Generally， the maximum flow rate of the pump is to times for mobile equipment，Elevator Price_ Hydraulic ladder_ Household elevator_ Household elevator - elevator manufacturer and to times for fixed equipment.

iClean the surface of the base and install the anchor bolts. If the installed construction hoist is installed on the basement floor， use pad iron under the base screws to increase the force bearing surface between the nut and the floor.Insert steel plate gaskets of different thicknesses between the plate and the foundation stone to adjust the verticality of the guide rail frame; install three standard sections and measure the verticality of the guide rail frame with theodolite; after the guide rail frame is vertically adjusted， and tighten the rest of the anchor bolts; install the buffer spring; use bolts to connect the other half of the fence to the front; adjust the verticality as above， tighten the anchor bolts， and loosen the cage The brake of the motor on the motor; use a crane to accurately position the cage from the top of the standard section， put the two cages on the guide rail frame respectively， and slowly place the buffer on the buffer spring. Prepare the drive frame for the two cages， and adjust each back wheel and roller to the clearance for the drive frame to be installed. Use lifting equipment to install the base of the lift on the standard section， and tighten the connecting bolts. Install the two groups of drive frames on the top of their respective cages， the pre-installation equipment should be fixed， and the reinforcement work should be carried out after confirming that the positions of the cables and oil pipes and the pre-installation frame are correct. Reinforcement requires welding or expansion screws， and the hydraulic freight elevator has firmness and safety after reinforcement.

QInspection basisIt is strictly forbidden to overload the mobile lifting platform during use， and the operators on the platform are not allowed to move during the lifting and lowering process.

qMThe working principle of the lifting platform is that the hydraulic oil is formed by the vane pump to form a certain pressure， and enters the lower end of the hydraulic cylinder through the oil filter， the isolation electromagnetic reversing valve， the throttle valve， the hydraulic control check valve， and the balance valve， so that the hydraulic cylinder The piston moves upward to lift the heavy object， and the oil returned from the upper end of the hydraulic cylinder returns to the oil tank through the isolating electromagnetic reversing valve. The rated pressure is adjusted by the overflow valve， and the reading value of the pressure gauge is observed by the pressure gauge.

The electromagnetic coil of the electromagnetic reversing valve is not fixed firmly， and frequent separation and engagement will also generate high noise.

In hotels， hospitals， and shopping malls， we often see hydraulic freight elevators. Compared with ordinary elevators， hydraulic elevators play an irreplaceable role. What are the specific advantages and disadvantages? Now let me introduce to you: the advantages of hydraulic elevators: safe and reliable. The working oil delivered by the main engine lifts the plunger to lift the car up. Bearing weight， high earthquake resistance， safe and reliable operation.

manufactureraThe hydraulic transmission system uses liquid as the working substance， which cannot be controlled in the relative speed of the hydraulic system. Coupled with the expansion of the liquid， it is difficult to solve the strict reduction ratio.

XTherefore， the oil should be changed regularly to ensure that the additives are effective. Filters can only absorb a limited number of dirt particles and other impurities from the oil. Change the filter at the recommended intervals to keep the system clean.

When the hydraulic lifting platform is working， the load cannot exceed its rated load. When it rises to a certain height， the greater the mass of the lifted object， the greater the shaking.

lFrisinBefore work， carefully check all parts of the mobile lifting platform， focusing on checking whether the screw connection is reliable， whether there is leakage of hydraulic pipeline components， and whether the wire contacts are loose or damaged.

rQSolution: Check whether the performance of the outrigger is good， even if it is polished with butter to increase its lubricity.

The oil suction pipe of the hydraulic oil pump must not be exposed to the oil surface
