Problems solved by technology
[0004] At present, most engineering vehicles at home and abroad use a fixed outrigger structure, which is compact in structure and takes up little space. However, it will be impossible to adjust the phenomenon during the work process. The outriggers are closer to the ground, which reduces the ground clearance of the vehicle and reduces the passability of the vehicle

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the drawings.
[0024] Such as figure 1 with figure 2 As shown, the outrigger mechanism of this construction vehicle includes a luffing frame 1 articulated to a fixed frame 7, a frame platform 2 that slides and retracts on the luffing frame 1, and is hinged to the luffing frame 1. The upper leg bracket 3 and the small connecting seat 6 are connected to one end of a connecting rod 5 through a large hinged connecting seat 4, and the other end of the connecting rod 5 is hinged to the small connecting seat 6 ;
[0025] Both ends of the leg support 3 are respectively installed with the lower roller 31 of the leg support and the upper roller 33 of the leg support, and the large connecting seat 4 is equipped with the large connecting seat roller 41; during the whole movement, the leg support The upper roller 33 can roll along the longitudinal beam of the frame platform 2.
[0026] The frame platform 2 is pr...

The invention discloses a supporting leg mechanism of an engineering van and the engineering van. The supporting leg mechanism of the engineering van comprises a variable-amplitude frame (1), a frame platform (2), a supporting leg support (3) and a small connecting seat (6). The supporting leg support is connected with a connecting rod (5) through a big connecting seat (4). The other end of the connecting rod is hinged to the small connecting seat. A lower supporting leg support idler wheel (31) and an upper supporting leg support idler wheel (33) are installed at the two ends of the supporting leg support respectively. A big connecting seat idler wheel (41) is installed on the big connecting seat. A platform vertical plate (21) is arranged on the frame platform. A small connecting seat idler wheel (61) is installed on the small connecting seat. By means of the supporting leg mechanism, potential safety hazards are eliminated, supporting legs are effectively protected, and the stability of the whole van is improved; the contact angle between the supporting leg mechanism and the ground can be adjusted automatically, and the requirements on various operation conditions are met; the passing capacity of the whole van is improved; the structure is compact, operation is easy and convenient, and the working efficiency of the whole van is remarkably improved.
Description
Technical field [0001] The invention relates to an outrigger mechanism, in particular to an outrigger mechanism of an engineering vehicle, and an engineering vehicle to which the outrigger mechanism is applied. Background technique [0002] In the prior art, many construction vehicles (for example, flat wreckers) are equipped with outrigger devices, which are used to provide stable support during the operation of the construction vehicle and prevent the head from tipping over due to excessive work load. [0003] Take a flat wrecker as an example. This wrecker is a special purpose vehicle for wrecking with dual functions of support and back load. The rear outrigger is its main component and plays a vital role in the working process. On the one hand, the performance of the outriggers directly affects the back-loading operation of the platform; on the other hand, the outriggers are a protective barrier for stability and safety during obstacle clearance operations. [0004] At present, ...
