Description

Bracket-type walking device and its integral rotation method technical field The application relates to a kind of support-type walking device for undulating ground construction or detection, mainly used in factory area It can be used in technical fields such as leveling construction, road or bridge deck concrete (cement) paving, and agricultural leveling construction. Background technique [0002] All kinds of construction machinery and construction equipment, its structure is mainly composed of two parts of the frame and the work part. of which the frame Part of it needs to realize the functions of vehicle transportation, construction transfer, support and guidance of the work department, and good frame structure design. The gage must ensure flexible overall movement, adapt to rough ground, and support stable and precise working parts. On this basis, the mechanical structure The design should be as simple, reliable, efficient, and low-cost as possible, while maximiz...

AI Technical Summary

Problems solved by technology

[0008] The main problems are: 1. It is necessary to pre-lay steel molds as the tracks for vehicles, which consumes extra labor and materials

2. Poor flexibility

[0011] The main problems are: 1. The wheelbase and wheelbase span of the car body are small, and the posture of the frame changes drastically on the undulating road surface, which is not conducive to the precise work of the work department, and the construction quality is affected

2. When constructing on the working surface of steel mesh or soft roadbed, the working surface will be sunken, and the vehicle will be more bumpy when walking

Reinforcement measures can be taken to avoid the depression of the working surface, but this will inevitably increase the construction cost

3. Low construction efficiency

[0014] The main problems are: 1. The bearing capacity of floating supports such as vibrating plates is limited, and they cannot support heavy work parts such as augers for a long time. When the cement viscosity is high and the road cement thickness is large, the construction quality is difficult to guarantee

2. There is still the limitation of low construction efficiency

[0017] The main problems are: 1. High cost. 2. The structure of the car body is heavy, and it is easy to damage the construction surface such as steel mesh or soft roadbed.

3. The working part is located on the outside of the frame, and the equipment must have a wide turning space during construction, so the flexibility is limited to a certain extent

[0020] The main problems are: 1. When the track and the cross beam are moved by means of the lifting mechanism of the working part, since the supporting span of the lifting mechanism of the working part is very small (about 2 meters), it is easy to cause the vehicle body to tilt to one side and touch the ground, or even overturned

In order to overcome this problem, the support span of the lifting mechanism of the working part can be considered to be greatly increased, but this will obviously reduce the moving stroke of the working part

2. Unable to realize the rotation of the angle of the body

Restricted by the direction of the track layout, the body can only translate along the front, rear and left and right directions, and it is difficult to complete the construction of diagonal crossing roads, curved roads and irregular areas

3. The track and the cross beam are only connected by moving pairs, which is not adaptable enough to the undulating construction surface

On rough roads, the rails on both sides cannot be guaranteed to be parallel and coplanar. When the span beam runs along the rail, if the driving force is insufficient, it is easy to slip or get stuck; if the driving force is sufficient, the span beam may pull the rail, causing the car body to Shaking, affecting the construction quality

4. When working, the support does not have the functions of leveling and height adjustment

In order to overcome this problem, a self-leveling support structure can be used for the rails on both sides, so that the rails on both sides are parallel and coplanar, but this obviously leads to an increase in system complexity and cost

[0021] Based on the above analysis, the frame structure scheme of the existing equipment is difficult to obtain the advantages of large span, low ground pressure, high stability (adapting to undulating road surfaces) and flexible walking at the same time
