Analysis of the basic working principle and structure drawing of the height adjustment board

The height adjustment board is also called warehouse adjustment cargo bed, height adjustment board, warehouse adjustment board, and hydraulic boarding car. The purpose is to achieve smooth connection with various freight cars of different heights by adjusting the height of the warehouse cargo bed, which is convenient for loading and unloading.

The height adjustment plate is a special auxiliary equipment for the rapid loading and unloading of goods. Its height adjustment function makes a bridge between the truck and the cargo bed of the warehouse. Through this, forklift trucks and other handling vehicles can directly drive into the truck for bulk loading and unloading. Only one person is needed to realize the fast loading and unloading of goods. The regulating board (abbreviation: boarding bridge) allows enterprises to reduce a lot of labor, improve work efficiency, and obtain greater economic benefits.

Working principle of height adjustment plate:

Press and hold the electric control button, the motor runs, the hydraulic pump works, and the main panel rises. When the panel reaches the maximum height, the hydraulically controlled directional valve opens, the spool oil cylinder works, and the slab opens. Then release the button, the hydraulic pump station stops working, the hydraulic boarding bridge descends under the effect of its own weight, so that the oil return of the panel oil cylinder flows back to the oil tank through the throttle valve, and the hydraulic boarding bridge slowly falls. After the loading and unloading work is completed, press and hold the electronic control button to lift the main panel, the slab is reset under its own weight, the oil return of the flap cylinder returns to the tank, release the button (can not reach the highest position of the main panel), the main panel descends and boarding hydraulically Bridge reset.

Structural diagram analysis:

The height adjustment board is composed of a panel, a slab, a bottom frame, a mechanical jack, a hydraulic transmission system, and electrical control. Its main components are shown in Figure 1.
