Description

Technical Field

[0001] This utility model relates to the technical field of oil drilling machinery and equipment, specifically to an oilfield derrick fixing rope device for steel wire ropes. Background Technology

[0002] In oilfield drilling projects, derrick ropes are used to fix the derrick structure. As an important component of tower-type derricks, the derrick rope system achieves horizontal adjustment and wind load resistance through the rope pulling device at the ground anchor point and the derrick base. A derrick is usually equipped with a rope pulling device in each of the four directions for fixation. The rope fixing device plays an important role in oilfield drilling projects.

[0003] After the fixed rope device has finished its work, the rope needs to be wound up. Due to the harsh environment of oil drilling projects, some debris and dust inevitably adhere to the surface of the rope. After the rope is wound up, the surface of the rope usually needs to be cleaned before winding it onto the drum. This not only consumes labor but also affects the winding efficiency. Therefore, a fixed rope device for oilfield derricks for steel wire ropes is proposed to solve the problems mentioned above. Utility Model Content

It has the advantages of cleaning and brushing away dust and debris adhering to the outside of the rope during winding, thereby improving winding efficiency. This solves the problem that cleaning the rope during winding is time-consuming and labor-intensive, affecting winding efficiency, in existing oilfield derrick fixing rope devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oilfield derrick rope fixing device for steel wire ropes, comprising a mounting frame, a winding drum rotatably mounted between the left and right inner walls of the mounting frame, a rope connected to the outer side of the winding drum, a sliding rod fixedly mounted between the left and right inner walls of the mounting frame in front of the winding drum, a slider slidably mounted on the outer side of the sliding rod, a lower fixing block rotatably mounted on the top of the slider, an upper fixing block rotatably mounted on the top left end of the lower fixing block, both the lower fixing block and the upper fixing block having arc-shaped opposite sides, a pair of symmetrically distributed cleaning mechanisms provided on each of the opposite sides of the lower fixing block and the upper fixing block, two limiting blocks fixedly mounted on the right side of the lower fixing block, and a T-shaped block rotatably mounted on the right side of the upper fixing block between the two limiting blocks; The cleaning mechanism described below includes two movable slots arranged in a ring on the inner side of the lower fixed block. A connecting block extending to the inner side of the lower fixed block is slidably installed on the inner side of each movable slot. An arc-shaped clamp is fixedly installed at one end of the connecting block located on the inner side of the lower fixed block. Brush bristles are fixedly installed on the inner side of the arc-shaped clamp. Two springs are fixedly installed between the outer side of the connecting block and the bottom wall of the inner side of the movable slot.

[0006] Furthermore, a gearbox connected to the left end of the winding drum is provided on the left side of the mounting frame, a rocker arm is provided on the left side of the gearbox, and a hand crank is movably provided on the front side of the rocker arm.

[0007] Furthermore, the left side of the crank handle has several limiting holes, and the right side of the rocker arm is threadedly fixed to the limiting holes on the crank handle by multiple bolts.

[0008] Furthermore, the length of each of the four arc-shaped clamps is greater than the thickness of the lower and upper fixing blocks, and the bristles are evenly distributed on the inner side of the arc-shaped clamps.

[0009] Furthermore, the cross-section of the connecting block is T-shaped, and the inner shape of the movable groove is adapted to the shape of the connecting block.

[0012] Compared with the prior art, this utility model provides an oilfield derrick fixing rope device for steel wire ropes, which has the following beneficial effects: This oilfield derrick rope fixing device for steel wire ropes works by moving the T-block away from the limiting block, at which point the upper fixing block loses its limiting position. Rotating the upper fixing block opens the rope, allowing it to be placed inside the arc-shaped clamps. Rotating the upper fixing block back to its original position allows the rope to be clamped and fixed by the four arc-shaped clamps. Rotating the T-block, in conjunction with the limiting block, fixes the upper fixing block. When the winding drum is rotated to wind up the rope, the bristles on the inner side of the four arc-shaped clamps clean the dust and debris adhering to the outside of the rope. This solves the problem of time-consuming and labor-intensive cleaning of the rope during winding up in existing oilfield derrick rope fixing devices, which affects winding efficiency.
