Problems solved by technology

[0005] 1. The overall drilling rig in the prior art can only maintain the level of the entire drilling rig by adjusting the length of the mechanical jack;
[0006] 2. The drilling rig in the prior art cannot automatically return to the initial installation position when the wheels deviate from the guide rail or the center of the base, and the drilling rig is prone to tipping over, which poses a great safety hazard

Embodiment 1

[0042] like Figure 1-3 As shown, the drilling rig moving and leveling device is composed of 4 mechanical jacks 1, 2 limit seats 2 and 2 connecting rods 3. The top of the mechanical jack 1 is fixedly connected to the derrick base 6, and the bottom of the mechanical jack 1 is connected to the limit The seat 2 is connected by compression, and the two limit seats 2 are connected through two connecting rods 3, and the connecting rod 3 is used to fix the distance between the two limit seats 2 to remain unchanged.

[0043] like image 3As shown, each drilling rig is equipped with four sets of drilling rig moving and leveling devices, which are distributed on the four corners of the derrick base 6 and fixedly connected with the four corners of the derrick base 6 respectively. Each set of drilling rig moving and leveling devices are connected with The guide rail 7 is matched, and the top of the derrick base 6 is fixedly connected with the derrick 8, and the bottom of the derrick base...

Abstract

The invention relates to the technical field of oil and natural gas drilling equipment, in particular to a drilling rig moving and transporting leveling device which can enable a drilling rig to automatically return to the initial mounting position when wheels deviate from the center of a guiding rail. The drilling rig moving and transporting leveling device comprises a mechanical jack, two limiting seats and a connecting rod. The top of the mechanical jack is fixedly connected with a base of the drilling rig. The limiting seats are in pressing-fixing connection with the bottom of the mechanical jack through first pressing plates, and the limiting seats are movably connected with the guiding rail through second pressing plates. The two ends of the connecting rod are movably connected withthe two limiting seats through pin shafts correspondingly. The drilling rig moving and transporting leveling device is simple in structure, the offset situation of the drilling rig can be automatically adjusted, the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas drilling equipment, in particular to a drilling rig transporting and leveling device capable of leveling a drilling rig that is tilted during the entire drilling process. Background technique [0002] The train-type drilling rig mobile device has the advantages of small ground specific pressure and can be adapted to harsh environments such as deserts, swamps and soft permafrost areas, and has an irreplaceable position by other drilling rig mobile devices. [0003] In the past drilling rigs, when the ground subsidence is soft and uneven and the guide rail is inclined, the length of the mechanical jack is adjusted to ensure the level of the drilling rig. After repeated leveling, the wheels of the drilling rig will deviate from the guide rail or the center of the base to support the drilling rig. The mechanical jack may also deviate from the guide rail or the base, and the drilling rig ca...
