As a necessary facility for pumping operations, wire ropes with a diameter of 16mm and a length of about 2500m are selected on site. During the pumping operation, it is wound on the drum of the well-draining machine, and the power of the well-draining machine is used to complete the up and down movement of the wire rope in the wellbore. After the pumping operation is completed, the pumping wire rope must be poured down from the well-draining machine drum and stored on the ground drum. Whether it is pouring the pumping wire rope from the well-draining machine drum to the ground drum, or vice versa, there is a problem, that is, when the drum is wound with wire ropes, it cannot be arranged neatly, and it is easy for the wire ropes to collapse after concentrated accumulation. During the handling process, the wire ropes suddenly bounce off and mechanical injuries occur. During the rope rewinding operation, two workers often use brown ropes to pull on both sides of the moving wire rope to change the winding track of the wire rope, so as to make the wire rope be arranged neatly on the drum. The bouncing wire rope may cut, pull down or even get drawn into the drum by the workers at any time, posing a very risky operation. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] The present invention discloses a roller device for winding and aligning a pumping wire rope. The device comprises a rope aligner bracket, a rope aligner sliding frame, a screw rod and a rope aligner. A slideway is arranged at the upper end of the rope aligner bracket, and the rope aligner sliding frame is arranged on the slideway of the rope aligner bracket through a roller.

It can ensure that when the drum is fully wrapped with a layer of pumping wire rope, the rope guide can realize automatic steering. No manual adjustment is required in the whole process, which reduces the difficulty of screw control and does not require forward and reverse rotation of the screw.

[0023] A method for winding and aligning a pumping wire rope drum utilizes the above-mentioned device to wind and align the pumping wire rope drum, thereby avoiding workers from contacting the pumping wire rope, improving the rope arranging efficiency and reducing the operation risk, effectively protecting the safety of the operators, and at the same time driving the drum body and the screw rod to rotate, so that within the time taken for the drum body to rotate one circle, the screw rod rotates and drives the rope arranging device to move a distance equal to the diameter of the pumping wire rope to be wound, which can ensure that the pumping wire rope to be wound around the drum body will not be piled up during the winding process.

[0024] Furthermore, during the winding process, the drum body to be wound and the screw rotate at the same angular velocity, and the pitch of the screw is equal to the diameter of the wire rope to be wound, ensuring that the wire rope to be wound can be tightly arranged during the winding process, thereby increasing the rope arrangement density of the drum body to be wound.
