Technical Field

The invention relates to a leveling mechanism and engineering machinery, in particular to a leveling mechanism and engineering machinery applied to complex working conditions, and belongs to the technical field of mechanical equipment.

Background

National pipe network construction projects are continuously increased, and the requirements on pipeline construction equipment are also continuously increased. At present, various special equipment for pipeline construction is developed and completed. However, since the construction of the long-distance pipeline is often carried out in mountainous areas, the mountain construction environment is severe, and the conventional equipment cannot meet the construction requirements. In order to better develop the pipeline construction of China to the direction of high quality, high technology and high efficiency, a working platform of construction equipment is required to have a leveling function so as to adapt to the special working condition of the mountain land. As mountain construction increases, the demand for level-adjustable construction equipment (e.g., level-adjustable excavators, level-adjustable cranes, level-adjustable heating carts, welding carts, etc.) also increases.

However, most of the existing leveling devices realize unidirectional leveling through an oil cylinder, and only can level forwards and backwards in a single direction in a walking direction, but cannot level in a vertical walking direction. The existing leveling technology can only level in one direction, but not level in two or more directions. The leveling equipment has poor construction effect on mountainous regions with relatively complex road surface conditions, construction sites often encounter existing transverse slopes and longitudinal slopes, the existing leveling equipment cannot be constructed, road surface finishing is required, and huge manpower and material resources are wasted.

Disclosure of Invention

The invention aims to overcome the defects that leveling equipment in the prior art cannot adapt to complex working conditions of mountainous regions and the prior art can only level in a single direction, and provides a leveling mechanism, which has the following technical scheme:

the leveling mechanism comprises a base, a platform and a first driving piece;

the base comprises a box body, two main force plates and two first lug plates, wherein the two main force plates and the two first lug plates are fixed above the box body;

the main force plates are provided with first through holes, the two main force plates are parallel to the first ear plate,

platform bottom symmetry respectively sets up two sets of second otic placodes and third otic placodes, and the second otic placode is articulated through first driving piece and first otic placode, and first driving piece drive platform is for base horizontal rotation, and the third otic placode is articulated with first through-hole.

Furthermore, the leveling device further comprises a second driving piece hinged with the leveling mechanism, and the second driving piece drives the leveling mechanism to rotate back and forth relative to the engineering machinery.

The engineering machine comprises the leveling mechanism and a chassis, wherein the leveling mechanism is hinged with the chassis through a second driving piece.

Compared with the prior art, the invention has the following beneficial effects:

the leveling mechanism and the engineering machinery with the leveling mechanism can realize leveling of both a track walking method and a direction perpendicular to the track walking direction, and are a simple, practical, safe, reliable and conveniently controlled universal leveling structure. The popularization and application of the invention can greatly save the construction difficulty of pipeline construction, greatly reduce the construction cost and become a sharp soldier sharp device in mountain construction.
