Description
Technical field
The present invention relates to it is a kind of with can integral demounting formula supporting leg vehicle frame, belong to crawler body technical field.
Background technology
With the development of wind-power market, the demand of the crawler body engineering machinery of various Custom Prosthesis is continuously increased, and is such as carried
The crawler crane of crawler belt Telescopic, because its grounding pressure is small, climbable gradient is big, and tractive force is big, can narrow gauge transition etc. it is various excellent
Point, and favored by many users, Telescopic track chassis will also be used in middle large-tonnage crawler belt lifting product by specifying.
Middle large-tonnage crawler crane chassis normal configuration is as shown in Figure 1, including vehicle frame, left and right track frame, front and back vehicle body
Five bulk such as counterweight is indispensable.
Middle large-tonnage crawler crane, host dead weight and size are all larger, are limited by transport law, it is necessary to track frame of dismantling
It transports later.During dismounting track frame, it is necessary to jack up vehicle frame to certain height, could smoothly realize track frame
Dismounting.The jack-up of vehicle frame need to be realized by the supporting leg on vehicle frame and the oil cylinder on supporting leg.And jack up vehicle frame
Four oil cylinders distribution it must also be ensured that in entire disassembly process equipment stability, so the distribution of four oil cylinders it is front and back,
Side-to-side dimensions needs are sufficiently large, then the size of supporting leg and oil cylinder is also larger.When vehicle frame is transported with host, working condition it is front and back to
Full-size be width dimensions when transporting, this size must satisfy the requirement of transport law.But in crawler body engineering
In machinery, in a certain range, the anteroposterior dimension of vehicle frame is bigger, and the stress of vehicle frame and track frame is better.
For the middle large-tonnage crawler crane using telescopic underpan, before making the present invention, if supporting leg is wanted to accomplish both
It can be transported with vehicle frame, and disassembled independent transport, then be necessarily required to rotate to left with vehicle frame in integrated travel position supporting leg
The parallel position of dextrad, as shown in Figure 2.In this structure, supporting leg seat is welded on vehicle frame, and supporting leg seat protrudes frame body, branch
The installation space of leg has tied up the sagittal space of vehicle frame, causes the sagittal size of vehicle frame to become smaller, is degrading vehicle frame, track frame
Stress.And if paying the utmost attention to accomplish maximum to size before and after vehicle frame, in the hinge for opening up supporting leg in agent structure
Point installs supporting leg, then supporting leg can not be rotated to vehicle frame or so to parallel position, as shown in figure 3, can only be by supporting leg when transport
It dismantles, there is no the possibilities integrally transported with host.
