Technical Field

[0001] The utility model relates to the technical field of oil extraction, in particular to a mobile rack for the maintenance of a top drive drilling device. Background Technique

[0002] The top drive drilling device is a drilling equipment used for oil and gas exploration and development. It is usually used to drill deep wells above the ground and provides downward pressure through the power system at the top to drill the underground rock formations. The main components of this drilling device include the drive system at the top, drill pipes, drill bits, as well as related control systems and operating platforms. When the top drive drilling device is being maintained, a mobile rack is used to move the disassembled top drive drilling device.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment

[0025] As Figure 1-6As shown in the figure, a mobile rack for the maintenance of a top drive drilling device proposed in an embodiment of the present utility model. The mobile rack designed in this solution can fix the components when hoisting the disassembled components of the top drive drilling device, avoiding the problem of unstable movement of the mobile rack caused by the shaking during movement. Moreover, it can perform side-down adjustment on the components according to different maintenance positions, improving the convenience of maintenance. It includes a mobile base 1 and a gantry 2. The mobile bases 1 are symmetrically arranged, and a gantry 2 is arranged on the two mobile bases 1. A limiting member 3 is arranged between the two mobile bases 1. The two ends of the limiting member 3 are respectively rotatably connected to two positioning members 4, and the two positioning members 4 are respectively fixedly connected to the two mobile bases 1. Two abutting members 5 are symmetrically threadedly connected to the limiting member 3. This device is electrically connected to an external control device through transmission wires, and the operating state of this device is controlled by the external control device. When hoisting the disassembled components of the top drive drilling device, the top of the components is hoisted by the hook assembly 205. Through the telescopic adjustment of the hydraulic cylinder 202, the vertical I-beam 201 can be lifted and lowered in the insertion slot 103, so that the overall height of the horizontal I-beam 203 can be adjusted and changed to meet the adaptation requirements of different top drive drilling device heights. After the hook assembly 205 finishes hoisting, by raising the hydraulic cylinder 202, the vertical I-beam 201 is lifted to the highest position. At this time, the top drive drilling device component suspended by the hook assembly 205 is above the fixed ring 301. When the mobile rack moves, by contracting the hydraulic cylinder 202, the vertical I-beam 201 descends, so that the hoisted top drive drilling device component falls to the inner ring of the fixed ring 301. Then, by rotating the handwheel 503, the screw 501 rotates in the threaded hole 302. The symmetrically arranged screws 501 on the fixed ring 301 will make the two handwheels 503 abut against the top drive drilling device component. Then, when the piston rod of the electric push rod 403 extends, the rectangular insertion block 404 will be inserted into the square insertion hole 304. Since the rectangular insertion block 404 is inserted and matched with the rectangular hole on the inner wall of the rotating column 401, the rotating shaft 303 can be limited inside the rotating column 401, and the rotating shaft 303 will not rotate. At this time, when the mobile rack moves, the hoisted top drive drilling device component will not cause the problem of unstable movement of the mobile rack due to shaking. When performing maintenance on the disassembled top drive drilling device component at different positions, since it is suspended, it is inconvenient to perform side maintenance on the top drive drilling device component. At this time, by contracting the electric push rod 403, the rectangular insertion block 404 is disengaged from the insertion of the square insertion hole 304, so that the rotating shaft 303 rotates freely in the rotating column 401. Then, in cooperation with the wire release of the hook assembly 205, when the hook assembly 205 releases the wire, according to the wire release required for the side-down of the top drive drilling device component, a pushing force is applied to the top drive drilling device component in this direction. Since the top of the top drive drilling device component is suspended by the hook assembly 205,The bottom contact member 5 is cooperatively connected to the limiting member 3. Therefore, when the hook assembly 205 pays out the wire, the suspended top drive drilling device assembly will rotate and fall sideways with the limiting member 3 as the center of the circle. The hook assembly 205 will rotate on the rotating seat 204, realizing the orientation adjustment of the top drive drilling device assembly on this device, facilitating maintenance at different positions, improving the use effect, being able to reduce the problem of inconvenient turning caused by placing the top drive drilling device assembly on the ground, and improving the convenient operation of maintaining the top drive drilling device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
