Vehicle winch drawing device

Abstract

The invention discloses a vehicle winch drawing device. The vehicle winch drawing device is characterized in that a positioning hole is formed in the front end of a support arm, a rope hole is formedin the bottom of the positioning hole, a connection hole is formed in the front end of a cantilever, a positioning block falling in the positioning hole is arranged at a front hanging part and provided with a sleeve, matched threads are formed outside the sleeve and in the inner wall of the connecting hole, the sleeve is provided with a prism bottom, a bottom hole opposite to the rope hole is formed in the bottom, and a pipe hoop is arranged in the sleeve, wherein a gap is formed between the pipe hoop and the inner wall of the sleeve; an adduction annular boss is arranged at the lower potion of the pipe hoop, expanding slices are distributed in the circumferential direction in the pipe hoop, reverse slant corners are arranged on the outer edges of the inner ends of the expanding slices, athrough hole which penetrates through front and back and is used for containing a drawing rope to penetrate through is formed in the center of a longitudinal column, a front-section notch and a back-section notch which are connected with the rope hole and the through hole are arranged on a slant arm, the front-section notch is opened towards the left portion, the back-section notch is opened towards the right portion, and both the front section of the bottom of the front-section notch and the back section of the bottom of the back-section notch are curved surfaces; unhooking can be avoided during loosing, bending deformation and friction of the drawing rope are small, and dead bending is not prone to generation.

Description

technical field [0001] The invention relates to a vehicle-mounted winch component for self-rescue of an automobile, in particular to a vehicle winch traction device. Background technique [0002] At present, there are a huge number of cars in our country. Some cars with special needs are equipped with winches at the front of the frame, such as off-road vehicles. Form a snare on the traction rope, and then start the winch to retract the traction rope to drive the vehicle out of trouble. Since the traction rope is composed of multiple strands of steel wire, the traction rope bends at the hook and causes friction and sliding. A dead bend occurs, which still needs to be solved technically. Contents of the invention [0003] In order to solve the above problems, the present invention provides a vehicle winch traction device. [0004] The technical solution adopted in the present invention is: a vehicle winch traction device, which is characterized in that it includes a main s...
