Description

Technical Field

[0001] The utility model belongs to the technical field of drilling rig mobile equipment, and in particular relates to a novel ratchet mechanism for drilling rig movement. Background Art

[0002] The mobile device of the drilling rig is a key equipment for the transportation of the entire support of the oil drilling rig or the derrick base. Among the many mobile methods, the rail-type ratchet mobile system has low installation and use costs and high cost performance, and is widely used in the entire support of land drilling rigs and offshore platforms.

[0003] The movement of the drilling rig sometimes requires pushing or pulling. When pulling is required, the conventional pawl seat needs to remove the pulling cylinder, and then the pawl seat needs to be turned 180 degrees and then connected to the pulling cylinder before pulling. And no matter it is pulling or pushing, the whole process requires manual operation of the anti-floating claw and adjustment of the pawl seat, which significantly reduces work efficiency. Utility Model Content

[0004] The utility model provides a novel ratchet mechanism for drilling machine movement, which can be adjusted from a pushing process to a pulling process by only rotating the ratchet 180 degrees, and the ratchet seat does not need to be adjusted laboriously during the whole process, thereby greatly improving the working efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel ratchet mechanism for drilling rig movement comprises a ratchet seat, a connecting ear plate is provided at the front end of the ratchet seat, a pin shaft 2 is provided on the connecting ear plate, and the ratchet seat is connected to the oil cylinder via the connecting ear plate; four ratchets are provided on the ratchet seat, and two of them are symmetrical on the left and right; the ratchet is rotatably connected to the fixed plate on the ratchet seat via a pin shaft 1; an anti-floating claw is provided at the middle position of the outermost fixed plate, and the ratchet seat is connected to the guide rail via the anti-floating claw; a ratchet hole is provided on the ratchet seat, and the protrusion on the ratchet is inserted into the ratchet hole, and the length of the ratchet hole is greater than the length of the slot on the guide rail.

[0007] Furthermore, anti-floating claws are provided on the outer sides of the connecting ear plates.

[0008] Furthermore, a handle is provided at the tail of the pawl.

[0009] Furthermore, the upper portion of the anti-floating claw is connected to the pawl seat via a bolt, and a spring washer is provided on the contact surface between the bolt and the pawl seat.

[0010] The beneficial effects of the utility model are as follows:

[0011] The utility model improves the pawl seat and designs four pawls into a movable structure. The pawl can be adjusted from the pushing process to the pulling process by simply rotating the pawl 180 degrees. The pawl seat does not need to be adjusted laboriously during the whole process, thereby greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
