A rope tensioner with a braking device

Abstract

The invention discloses a rope tensioner with a brake device, which comprises two movable pulleys hinged inside the upper and lower ends of the box body; also includes brake bolts, brake nuts and brake wheels; between the two movable pulleys The front and rear panels of the box body are provided with clutch sliding slot holes, the lower part of the brake bolt is provided with a shoulder, the circumference of the brake wheel is provided with arc grooves, and the inner wall of the vertical plate on the left side of the box body is There is a hoisting rope chute on the top, the brake bolt passes through the hole of the clutch slide slot, the brake wheel is located in the inner cavity of the box and is coaxially fixed with the brake bolt, and the outer diameter of the brake nut is larger than the clutch slide slot The width of the hole, the brake nut is on the front panel of the box body and connected with the brake bolt through threads. The invention can quickly brake the hoisting rope, avoid manual tying or dismantling of the rope buckle, has obvious braking effect, strong operability, can save time, labor and labor, improve work efficiency, ensure safe production, and successfully complete the hoisting work.

Description

technical field [0001] The invention relates to the technical field of hoisting tools, in particular to a rope tensioner with a braking device. Background technique [0002] In the erection of power tower poles, the hoisting of transformers, the overhaul of generator sets, etc., heavy lifting will use lifting point swing ropes to prevent the lifting objects from overturning. The four positioning swing ropes need to frequently adjust the tightness and angle of the ropes. In the prior art, it is usually necessary to brake the rope at the lifting point for hoisting heavy objects, and the tail end of the rope at the lifting point is tied manually. The operation of dismantling the rope buckle requires a lot of people to pull the rope, which requires a lot of human arm strength and hurts the opponent. Sometimes the rope is forced to be cut off and causes waste. Time-consuming and labor-intensive, and the hoisting work efficiency is low. Contents of the invention [0003] The t...

Problems solved by technology

In the prior art, it is usually necessary to brake the rope at the lifting point for hoisting heavy objects, and the tail end of the rope at the lifting point is tied manually. The operation of dismantling the rope buckle requires multiple people to pull the rope, which requires a lot of human arm strength and will hurt the opponent. Sometimes the rope is forced to be cut off and causes waste. Time-consuming and labor-intensive, and the hoisting work efficiency is low
