Description
Technical Field
The utility model relates to a lifting support mechanism of dock wall car.
Background
The dock wall vehicle is arranged on a dock wall of a dock, is very harsh in use environment and is often in outdoor operation in high seawater corrosion, sunlight exposure and wind and rain.
The following problems are likely to occur when the operation platform is lifted:
1. dithering: when the operation table is started in a lifting way and is frequently replaced, the shaking phenomenon of the operation table is easy to occur.
2. Inclination: in the use process of the workbench, the left balance connecting rod and the right balance connecting rod are asymmetric, and the workbench is easy to incline.
3. Stopping the machine: under the adverse circumstances, the balanced connecting rod of both sides is asynchronous, and the atress is uneven causes the bending of balanced connecting rod, and the operation platform shuts down, can't move. The dock wall vehicle provides lifting operation of a working platform for constructors for ship repair and building, and plays a very key role in the operation of the ship repair and building of the dock due to the characteristics of flexible operation, strong adaptability, compact structure, high use efficiency, safety and reliability.
The prior art mostly adopts the following steps when dealing with the instability of the operation platform under severe environment operation:
1. the design method of the double-side single-row balance connecting rod is used for coping with the inclination of the workbench.
2. The fit clearance is minimized. Although the dock wall vehicle in the prior art adopts a bilateral balance connecting rod design, the structure is unstable, and the operation platform still shakes and inclines during lifting operation, even is clamped, so that the shutdown risk is caused.
Disclosure of Invention
For overcoming prior art's defect, the utility model provides a dock wall car's lift supporting mechanism, the technical scheme of the utility model is:
a lifting support mechanism of a dock wall vehicle is arranged between a fixed arm and a driven arm of a dock wall vehicle main body and comprises a plurality of connecting units which are sequentially connected together, each connecting unit comprises two connecting rods which are parallel to each other and form a space, one end of each connecting rod is provided with an inserting column, the other end of each connecting rod is provided with a fork plate, when two adjacent connecting units are connected, the inserting column of one connecting rod of the connecting units 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 on one side to connect two adjacent connecting rods together; the other end of the connecting column penetrates through the fork plate and the inserting column on the other side, and then two adjacent connecting rods are connected together; two ends of the connecting column are respectively provided with a vertical rod, the lower end of each vertical rod is arranged on a bracket of the dock wall vehicle main body, and the brackets and all the connecting units are arranged in parallel.
The connecting column comprises a sleeve, pin shafts and end covers, the end covers are welded to two ports of the sleeve respectively, the pin shaft is welded to the outer side of each end cover perpendicularly, and the pin shafts penetrate through the fork plate, the inserting column corresponding to the fork plate and the upright post in sequence and then are provided with split pins.
The utility model has the advantages that: on the basis of a traditional dock wall vehicle, a balance connecting rod single structure is improved, an integral frame type design scheme is adopted, the lifting stability of an operation platform is improved, and the shutdown risk is reduced.
