Vehicle frame structure with novel supporting leg seats and supporting legs

Abstract

The invention discloses a vehicle frame structure with novel supporting leg seats and supporting legs. The supporting legs, supporting leg oil cylinders and the supporting leg seats are arranged in the space between the upper plane of a vehicle frame and the lower plane of a rotary table and can completely retract in the space between the rotary table and the vehicle frame or can rotate out of thespace between the rotary table and the vehicle frame, and the vehicle frame is supported. The supporting leg seats are placed on the upper portion of a vehicle frame body and not occupy the space inthe front-rear direction of the vehicle frame body so that the spatial size can be fully used for structural design of the vehicle frame body, and the bearing capacity of the vehicle frame and a crawler frame is optimized to the maximum degree. The supporting leg seats are placed in the space between the vehicle frame and the rotary table, the idle space is effectively used, and the structural design is more compact. The supporting leg seats, the supporting legs and the supporting leg oil cylinders are rotationally placed in the height space between the vehicle frame and the rotary table, thesize in the front-rear direction is strictly controlled within 2.55 m, and the transportation width size of a main machine meets the requirements of transportation laws and regulations to the maximumextent.

Description

technical field [0001] The invention relates to a vehicle frame structure and belongs to the technical field of crawler cranes. Background technique [0002] With the continuous improvement of national transportation regulations, the control of the size and weight of various workpieces that need to be transported by road is becoming more and more strict. If the size and weight of the workpiece exceed the standard, the workpiece cannot be transported. [0003] For crawler-type lifting and transporting machinery, due to the need to bear a relatively large load, the general size and weight are relatively large, and existing products generally have the problem of excessive size and weight. [0004] Small-tonnage crawler cranes using telescopic crawler chassis also have the problem of excessive transport size and weight of the main engine. In order to reduce the transportation weight of the main engine, it is usually necessary to remove the crawler frame 10 for transportation. ...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: the outrigger seat a4 is embedded on the main body a21 of the frame, the rotation angle of the outrigger a3 is greatly restricted, and it cannot be rotated to a position parallel to the left and right of the frame, and the outrigger a3 can only be rotated to a position parallel to the left and right of the frame. Remove a3 and outrigger cylinder a31

The shortcoming of this method is: this method itself is adapted to the use of the crawler chassis of medium and large tonnage grades, when used in the crawler chassis of the corresponding small tonnage grade of the present invention, it will cause complex structure, high cost, low disassembly efficiency, etc. question
