Problems solved by technology
In order to improve its rigidity and strength, the size and thickness of the board are increased, resulting in heavy weight, which affects the lightweight design of the back carriage and makes the whole vehicle unable to meet the road requirements
[0004] The inventors have found that there are at least the following problems in the prior art: the existing vehicle-mounted deep well drilling rig has an unreasonable structural design of the back drilling rig carriage, and the back carriage is weak in rigidity and strength, causing the vehicle-mounted deep well drilling rig to twist when lifting and falling the tower. The deformation is large, and the weld seam is easy to tear, which affects the stability of the whole vehicle; although the rigidity and strength are improved after strengthening the structural size, the weight is heavy

The invention discloses a drilling-rig sliding frame structure and a drilling rig, and relates to the field of engineering machinery. According to the drilling-rig sliding frame structure and the drilling rig, the drilling-rig sliding frame structure is optimized, and the light weight of the drilling-rig sliding frame structure is achieved in the premise of ensuring the bending moment and torque bearing capacity of the drilling-rig sliding frame structure. The drilling-rig sliding frame structure comprises sliding blocks and two or more load-bearing structures, and all the load-bearing structures are connected through rod pieces; and the sliding blocks are mounted on the load-bearing structures, and the length directions of all the load-bearing structures are parallel or intersect. According to the technical scheme, the length directions of the load-bearing structures intersect with the length directions of the rod pieces, when the drilling-rig sliding frame structure is used, the load-bearing structures mainly bear bending moment, and the rod pieces are connected with the load-bearing structures so that the load-bearing structures can effectively bear torque; and on the other hand, due to the fact that the rod pieces are low in weight, the light weight of the whole drilling-rig sliding frame structure can be realized.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a drilling rig sliding frame structure and a drilling rig. Background technique [0002] Vehicle-mounted deep well drilling rigs are more and more widely used in the development of natural gas, coalbed methane, shale gas and other energy sources in recent years due to their strong mobility and convenient transition. The drilling tower structure of the vehicle-mounted deep well drilling rig is subjected to complex forces and bears tension, compression and torsional loads. The carriage structure of the back drilling rig is an important component of the drilling tower structure and is the direct carrier for the drilling tower to overturn. When the vehicle-mounted deep well drilling rig lifts and lowers the tower, the center of gravity of the drilling tower structure is higher than the back carriage, so that the back carriage bears a large bending moment; during drilling operatio...
