A hydraulic support control box

Abstract

A hydraulic support control box includes a base plate, a lifting assembly on the base plate, several limiting components on the base plate, and a fixing component on the lifting assembly. This utility model, as a hydraulic support control box, ensures the smoothness and reliability of the lifting process through its multi-stage transmission structure, effectively solving the problem of traditional support devices being unable to adapt to different pipe installation heights. The gear and rack meshing transmission method has high transmission accuracy and self-locking characteristics, which can stably maintain the adjusted support height and avoid displacement deviations caused by load changes. The entire mechanism, through modular design, converts linear motion into rotational motion and then back into linear lifting, achieving a large height adjustment range within a limited space, significantly improving the adaptability of the support device to different pipe diameters and installation conditions.

Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, specifically to a hydraulic support control box. Background Technology

[0002] The hydraulically adjustable support pressure constant system is mainly used during fracturing and flowback operations to ensure that large-diameter manifolds are always stably supported. During operations, fluid flow within the large-diameter pipeline can cause vibrations in the pipeline and wellhead, potentially leading to loosening of the screw supports. If this loosening accumulates to a certain extent, it can damage the wellhead equipment, even causing it to tilt and deform, and in severe cases, leading to wellhead overturning. Therefore, it is necessary to monitor the support tightness of the large-diameter manifold in real time and, when necessary, to intervene and adjust it remotely to maintain its stability under the action of hydraulic support.

[0003] The current support device has certain limitations in its adjustment function, and cannot flexibly adapt to the installation spacing between different pipes and the ground. As a result, when dealing with the support needs of pipes of various height specifications, the adjustment efficiency is low, the scope of application is limited, and the actual use efficiency is affected. Utility Model Content

The sleeve is mounted on the base plate, a lifting rack is movably disposed within the sleeve, a lifting plate is disposed on the lifting rack, the fixing frame is mounted on the base plate, a rotating shaft is movably disposed on the fixing frame, a rotating gear is disposed on the rotating shaft and meshes with the lifting rack, a rotary gear is disposed on the rotating shaft, and a drive assembly is disposed on the base plate.

[0007] Preferably, the base plate is provided with pads.

[0008] Preferably, the drive assembly includes a support frame and a connecting plate. The support frame is mounted on the base plate, and an electric push rod is provided on the support frame. A movable rack is movably provided on the support frame, and the connecting plate is mounted on the drive end of the electric push rod and connected to the movable rack.

[0009] Preferably, the electric push rod is fixed to the support frame by bolts.

[0010] Preferably, the fixing component includes a placement frame mounted on the lifting plate, a double-ended threaded rod movably disposed on the placement frame, a first gear disposed on the double-ended threaded rod, a motor disposed on the placement frame, a second gear disposed on the drive end of the motor and meshing with the first gear, a guide rod disposed on the placement frame, and a clamping frame movably disposed on the double-ended threaded rod and movably connected to the guide rod.

[0011] Preferably, the lifting plate is provided with a mounting bracket.

[0012] Preferably, one of the plurality of limiting components includes a fixed cylinder and a lifting rod.

[0013] Preferably, the card slots are provided in a plurality of manners.

[0014] The beneficial effects of this utility model are as follows: As a hydraulic support control box, this utility model, through its lifting structure and multi-stage transmission structure, ensures the stability and reliability of the lifting process, effectively solving the problem that traditional support devices are difficult to adapt to different pipe installation heights. The gear and rack meshing transmission method has high transmission accuracy and self-locking characteristics, which can stably maintain the adjusted support height and avoid displacement deviation caused by load changes. The entire mechanism, through modular design, converts linear motion into rotational motion and then back into linear lifting, achieving a large height adjustment range within a limited space, significantly improving the adaptability of the support device to different pipe diameters and installation conditions. Through several limiting structures, this limiting mechanism achieves rapid locking of the lifting rod position through the insertion and cooperation of the limiting shaft and the locking hole, effectively preventing accidental deviation of the support height under load. The nested structure of the fixed cylinder and the lifting rod enhances overall rigidity, while the through-type limiting design ensures the reliability of the mechanical locking. This design retains the flexibility of height adjustment while providing stable static load-bearing capacity. Through the fixed structure, gear transmission drives the synchronous movement of the bidirectional threaded rod, achieving counter-linkage of the clamping frame. This ensures accurate positioning of the pipe center and effectively avoids uneven loading caused by unilateral pressure application. The double-ended threaded structure, combined with the guide rod, forms a precision linear motion pair, possessing both high transmission efficiency and motion stability, resulting in uniform and quantifiable controllable clamping force distribution.
