Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a cable towing rope operating device. Background Art

[0002] Cable tow ropes are a tool used to pull or drag heavy objects and are widely used in power systems. When selecting the right cable tow rope, there are several factors to consider, including load capacity, durability, environmental conditions, cable length, as well as flexibility and ease of use. When using a cable tow rope, it must be regularly inspected and maintained to ensure its safety and reliability.

[0003] The opening of the cable tow rope can be radially opened by axial compression, and the opened cable tow rope puts the cable inside, and then the opening of the cable tow rope is closed again. The more the user pulls the net sleeve, the more the net sleeve contracts radially and firmly fixes the cable. However, the cable tow rope in the prior art has the following problems: since the cable tow rope is made of steel cable, it is very labor-intensive to press the tow rope to keep it radially opened, so it is necessary to design a tow rope operating device that can keep the cable opening radially opened. Summary of the invention

The tightening device also includes a driving gear sleeved on the tightening circular shaft and connected to the driven gear, and a transmission cross bar arranged on the inner wall of the driving gear and plugged into the transmission through hole; The one-way lock includes a small-diameter through hole arranged at the upper end of the tightening socket, a one-way circular cavity arranged above the small-diameter through hole, a one-way roller rotatably arranged in the one-way circular cavity, a transmission socket arranged at the lower end of the one-way roller and coordinated with the transmission cross bar, and ratchet slots circumferentially evenly distributed on the outer wall of the transmission socket. The one-way lock also includes a spring slot arranged on the side of the one-way circular cavity, a locking compression spring arranged at the bottom of the spring slot, and a one-way ratchet slidably arranged in the spring slot and abutting against the locking compression spring. The one-way ratchet is plugged into the ratchet slot to realize the one-way rotation of the one-way roller.

[0005] The adjusting cylinder is rotatably arranged in the upper circular cavity and located at the inner edge of the inner ring of the upper cavity. The lower half of the outer wall of the adjusting cylinder is provided with an adjusting gear. One end of the reset torsion spring is connected to the plane threaded disk and the other end is fixedly connected to the inner wall of the adjusting cylinder.

The tightening device also cooperates with the one-way lock to realize one-way rotation, so as to prevent the telescopic clamp from automatically moving outward and resetting before it moves inward into position.
