Lifting supporting mechanism of dock wall vehicle

Abstract

The invention relates to a lifting supporting mechanism of a dock wall vehicle. The lifting supporting mechanism is installed between a fixed arm and a driven arm of a dock wall vehicle body and comprises a plurality of connecting units connected together in sequence, each connecting unit comprises two connecting rods which are parallel to each other and form a distance, one end of each connectingrod is provided with an inserting column, and the other end of each connecting rod is provided with a fork plate; and when two adjacent connecting units are connected, the inserting column of the connecting rod of one connecting unit extends into the fork plate of the connecting column of the other connecting unit, and one end of the connecting column sequentially penetrates through the fork plate and the inserting column at one side to connect the two adjacent connecting rods together. The lifting supporting mechanism has the advantages that on the basis of a traditional dock wall vehicle, the structure of a balance connecting rod single body is improved, an integral frame type design scheme is adopted, the lifting stability of a working platform is improved, and the shutdown risk is reduced.

Description

technical field [0001] The invention relates to a lifting support mechanism for a dock wall vehicle. Background technique [0002] The dock wall truck is installed on the dock wall of the dock, and the operating environment is very harsh. It is often operated outdoors in high seawater corrosion, sun exposure, and wind and rain. [0003] The following problems are prone to occur when operating the workbench up and down: [0004] 1. Vibration: When the workbench is lifted and started and the position is changed frequently, it is very easy to cause the workbench to vibrate. [0005] 2. Tilting: During the use of the workbench, the left and right balance links are asymmetrical, and the workbench is prone to tilt. [0006] 3. Shutdown: In harsh environments, the balance connecting rods on both sides are not synchronized, and the uneven force causes the balance connecting rods to bend, and the workbench stops and cannot operate. The dock wall truck provides the lifting operatio...

AI Technical Summary

Problems solved by technology

[0004] 1. Jitter: When the workbench is lifted and started and the position is changed frequently, it is very easy to cause the workbench to shake

[0005] 2. Tilt: During the use of the workbench, the left and right balance connecting rods are asymmetrical, and the workbench is prone to tilt

[0006] 3. Shutdown: In harsh environments, the balance connecting rods on both sides are not synchronized, and the uneven force causes the balance connecting rods to bend, and the workbench stops and cannot operate.

Although the dock wall truck in the prior art adopts the design of double-sided balance connecting rods, the structure is unstable, and the worktable still shakes, tilts, and even gets stuck during the lifting operation, causing the risk of downtime
