Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a hydraulic wrench shifting device. Background Art

[0002] In the field of oil and gas transportation, pipelines are key long-distance transportation tools, carrying important energy sources such as oil and natural gas. However, during long-term use, oil and gas pipelines will inevitably be affected by factors such as natural corrosion, geological changes or human operations, resulting in pipeline damage or maintenance. In order to ensure the continuity and safety of oil and gas supply, non-stop plugging technology came into being, allowing the pipeline to be repaired or modified without affecting the normal transportation of the pipeline, and the hydraulic wrench shifting device has become an important tool in the implementation of non-stop plugging projects.

[0003] The existing Chinese patent with announcement number CN212665924U discloses a hydraulic wrench displacement device, which includes an annular platform, a blocking three-way connector, a sliding structure and a platform lifting structure. The blocking three-way connector is connected to one side of the annular platform, and the other side of the annular platform has a coaxial annular groove. The sliding structure includes a hydraulic wrench connection platform and at least two rollers. The platform lifting structure is connected between the hydraulic wrench connection platform and the rollers, and the at least two rollers are arranged in the annular groove.

[0004] Although the above scheme can reduce the time required for connecting the flange and the clamping valve and improve maintenance efficiency, the device is relatively cumbersome to fix the hydraulic wrench, which affects its use. In addition, it is inconvenient to adjust the angle of the hydraulic wrench after it is fixed, which affects the use effect. Therefore, it does not meet the existing needs. In this regard, we propose a hydraulic wrench shifting device. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a threaded rod rotatably arranged on one side inside the clamping seat. When the operator turns the first knob, the threaded rod can drive the clamping plate to rotate synchronously. Since the clamping plate and the two guide rods are slidably matched, the clamping plate can move vertically up and down. After the hydraulic wrench is placed on the upper end of the clamping seat, the downward movement of the clamping plate can clamp and fix the hydraulic wrench. The anti-slip pad can increase the friction force to avoid sliding after clamping and fixing. At the same time, it can avoid wear on the outer shell of the hydraulic wrench, so that the hydraulic wrench can be quickly fixed. The operator only needs to turn the first knob to complete the fixation. The operation is simple and easy to use.

[0017] 2. The utility model has a transmission inside the movable seat. When the operator turns the second knob, the second knob drives the transmission worm to rotate. Under the worm transmission, the transmission worm wheel drives the rotating shaft to rotate synchronously. The rolling of the ball in the annular groove makes the rotation of the clamping seat more stable, so that the angle of the hydraulic wrench after clamping can be adjusted. Since the worm transmission has self-locking properties, the position of the hydraulic wrench driven by the clamping seat is not easy to change after it is fixed, thereby ensuring stability during use.

[0018] 3. The utility model provides protective covers on the upper end of the clamping seat and one side of the movable seat. The protective covers are connected to the clamping seat and the movable seat through damping hinges. After rotating the first knob and the second knob, the operator can rotate the protective cover through the damping hinge so that the protective cover protects the first knob and the second knob to prevent accidental touch during use from affecting the overall stability.
