Description

Technical Field

[0001] The invention belongs to the technical field of winches, in particular to a laying winch capable of tension compensation. Background Art

[0002] During the operation of the winch, if there is no tension detection and compensation mechanism, the cable may become loose or too large, resulting in poor rope arrangement and tangled ropes. In addition, the lack of tension adjustment will cause the winch to operate unstably, and vibration or shaking may occur, affecting the normal use of the winch and the service life and safety of the cable.

[0003] Although the current workshop has designs for tension adjustment, it is not possible to automatically adjust the tension in real time according to the cable release speed or tension requirements.

[0004] Therefore, there is an urgent need to design a tension-compensating laying winch. Summary of the invention

[0005] The purpose of the present invention is to provide a tension-compensated laying winch with high flexibility. The tension of the cable during the cable laying or cable reeling process is detected by a tension detection mechanism, and insufficient or excessive tension of the cable is discovered in time, thereby avoiding equipment damage due to insufficient tension or safety accidents caused by excessive tension, ensuring the safety of the winch working process. When insufficient or excessive tension is detected, the tension compensation mechanism automatically adjusts the tension according to the tension demand of the cable, solving the problem of poor rope laying effect caused by the current cable being loose or too large, improving the service life and safety of the cable, and ensuring the stability and safety of the winch during use.

[0006] In order to solve the above-mentioned technical problems, the present invention provides a tension-compensated laying winch, including a winch body, the winch body including a base, a winch frame, a drum, a cable, a tension compensation mechanism and a tension detection mechanism, the winch frame is slidably arranged on the base, the drum is arranged on the winch frame, one end of the cable is wound around the drum, and the other end extends out of the drum, and is connected to an external bearing device through the tension compensation mechanism and the tension detection mechanism in sequence.

[0007] Preferably, the tension compensation mechanism comprises a mounting seat, a movable pulley mounting frame, a movable pulley and a telescopic cylinder, the mounting seat is mounted on the outside of the base, a fixed pulley is mounted on one side of the mounting seat, and the movable pulley mounting frame is rotatably mounted on the other side, the movable pulley is mounted on the movable pulley mounting frame, the telescopic cylinder is mounted on the movable pulley mounting frame, and its output end is fixed to the mounting seat.

[0009] Preferably, a sliding seat is provided under the winch frame, and the sliding seat is slidably set on the base through a sliding mechanism. The sliding mechanism includes a sliding rail, a sliding block and a rope-arranging hydraulic cylinder. The sliding rail has a pair and is symmetrically arranged on the base.

[0016] 4. The present invention can improve the efficiency and accuracy of rope arrangement through the design of the rope arrangement hydraulic cylinder, ensure work safety, adapt to various working environments, and improve the reliability and maintainability of the winch body during operation.

[0028] The present invention detects the tension of the cable during the process of releasing or reeling in the cable through the tension detection mechanism 16, and promptly discovers the situation that the cable tension is insufficient or too high, thereby avoiding equipment damage caused by insufficient tension or safety accidents caused by excessive tension, ensuring the safety of the winch working process. When insufficient or excessive tension is detected during the specific operation process, the tension compensation mechanism 15 automatically adjusts the tension according to the tension demand of the cable, solving the problem of poor rope arrangement effect caused by the current cable being loose or too large, thereby improving the service life and safety of the cable, and ensuring the stability and safety of the winch during use.

[0029] The tension-compensated laying winch of the present invention can meet applications with different tension requirements, and in the process of laying out or reeling in the cable, appropriate tension adjustment is performed through the tension compensation mechanism 15, thereby reducing the vibration and jitter of the winch and improving the stability of the winch during operation; and here, the design of the winch frame 12 being slidably arranged on the base 11 can enable the winch frame 12 to remain stable during operation, reduce damage caused by factors such as vibration and impact, and help improve the working efficiency and service life of the winch.
