8n = 49,000n For the work of hydraulic lifting platform, the primary load is gravity load. Through the cooperation of these mechanisms, the constant and reliable operation of the elevator is achieved. When there are many adjacent components, the positions of the holes are not easy to determine. The maximum length, width, and height dimensions of a hydraulic lift carrier vehicle are the dimensions of a single parking space of 2000 mm × 2,500 mm (height × width), the maximum weight is 5 t, and the lifting height is 0.55 m. . In order to make the structure have brilliant invariance, reliability and control precision, and determine a reasonable mechanical structure design scheme, it is necessary to conduct a modal analysis of the system. 48l / min Shenyang Industrial University Undergraduate Design 13 Look-up table [4] Extract the gear pump cb3-.

1 Working cycle diagram of the hydraulic lifting platform Figure 6 shows the cycle of the ascending and descending movements of the lifting platform of the underground garage. The computer interface should also be unified and compatible. Vertical cycle type, coded as cx; refers to parking equipment where the vehicle carrier moves continuously in the vertical plane to realize the vehicle access function; horizontal cycle type, coded as sx; refers to the vehicle carrier in the horizontal plane. Take 2 or more rows of parking equipment for continuous revolving between rows to realize vehicle access. 6 Calculation and selection of hydraulic components. In order to prevent the pallet from falling due to pipe splitting during operation, another method is to install the ball logic valve around the hydraulic cylinder. When the pipe is split for some reason, the ball logic valve is immediately blocked to prevent the pressure oil in the cylinder from flowing out. , The pallet will not fall and cause a car crash.

Chapter 1 Overview of Hydraulic Lifting Platform Hydraulic lifting platform is a kind of multifunctional lifting loading and unloading machinery and equipment. Others When the oil pump is started and checked, the relief valve should be unloaded; the set pressure of the relief valve must not exceed the maximum pressure of the hydraulic system; the voltage of the solenoid valve should be connected as much as possible, otherwise the coil may be heated. In every situation, the holophane series costs more per lamp than fluorescent lamps. The modal analysis of the stage structure in this article belongs to the linear elastic unit, and the material characteristics in the structure are constant. Clean the filter at the same time when changing the oil. Wipe the material before installing the filter element to really clean the dirt on the bottom of the filter case. Adjust the relief valve from scratch. The fixed hydraulic lifting platform lifting structure is safe, low failure rate, reliable operation, safe and efficient, simple and convenient maintenance, and economical and applicable. Look up the rod diameter ratio d / d, generally according to the following principles: When the piston rod is pulled, d / d = 0. 3-0.

Hydraulic lifting platforms are commonly used in various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting requirements of different homework heights, and can be equipped with various table forms (such as ball, roller , Turntable, steering, tipping, telescoping), with various control methods (transfer, linkage, explosion-proof), has the characteristics of smooth and accurate lifting, frequent start, heavy load, etc., useful to solve various lifting tasks in industrial enterprises Difficult points, make production homework easy. 5t. The flow of the pump is a static analysis of the structure of the stage lifting platform using finite element software. The deformation and stress conditions of the platform under the external load are analyzed, and the displacement and stress values of its largest deformation are obtained to ensure the structure's The components meet the design requirements and improve the safety of the lifting platform.

The lifting platform lifting system is driven by hydraulic pressure, so it is called electro-hydraulic lifting platform. 2 Lift mechanical structure form and reasoning ............... Vertical lifting class, code name It is cs; it refers to the parking equipment where the parking spaces are distributed around the hoistway, and the hoisting and lowering operation is performed in the dedicated hoistway by the lifting conveyor to realize the vehicle access function. 1.2 Introduction to the products of fixed hydraulic lifts The fixed hydraulic lift is a kind of good lifting invariance. The widely used cargo lifting equipment is mainly used for the transportation of cargo between the height difference of the production line. The materials are brought on and off the assembly line. Adjusting the height of the workpiece; Feeding from the feeder at high altitude; Lifting of timing components for large-scale equipment; Loading and unloading of large-scale machine tools; Warehousing and loading sites and forklifts and other handling vehicles for fast loading and unloading.
