Anti-panic rope ascender / descender equipment

Abstract

The invention discloses anti-panic rope ascender / descender equipment. The anti-panic rope ascender / descender equipment comprises a body, a movable cam and a releasing and clamping mechanism, wherein a lockhole is formed in one end of the body, one end of the movable cam stretches into the end, deviating from the lockhole, of the body, the end of the body is hinged with the movable cam, and a first rope threading gap is formed between the end of the movable cam and the body; the releasing and clamping mechanism comprises a handle, a first friction element and a second friction element, andthe first friction element and the second friction element are arranged on the handle; one end of the handle is hinged with the end, deviating from the body, of the movable cam; and a second rope threading gap is formed between the first friction element and the second friction element. The anti-panic rope ascender / descender equipment is simple in structure, by arranging the first rope threadinggap, the second rope threading gap and the movable cam, the anti-panic rope ascender / descender equipment is smooth when a rope ascends and is locked automatically within a very short travel when the rope is loaded, and self-locking can be achieved during descending when a user instinctively clenches the handle due to panic caused by rapid falling.

Description

technical field [0001] The invention relates to an anti-panic rope ascender / descender device, which is suitable for outdoor expansion, high-altitude rescue, aerial work and other fields requiring climbing. Background technique [0002] Rope is often used as one of the most common and easiest escape tools, and it is widely used in outdoor climbing, high-altitude operations, high-altitude rescue, and high-rise escape. However, the disadvantage of the rope is that it has a very large potential safety hazard. If there are no other safety measures during use, most people dare not use it at high altitudes, and there is a very high possibility of secondary injury. Therefore, when the rope is used at high altitude, it is usually used in conjunction with other safety protection mechanisms.

However, the disadvantage of the rope is that it has a very large potential safety hazard. If there are no other safety measures when using it, most people dare not use it at high altitude, and there is a very high possibility of secondary injury.

[0003] The Chinese invention prior patent with the application number 201110238172.9 discloses an ascender / descender device for climbing and descending on a rope, which includes a main body with an attachment device connected with a harness on the user's body, and a The clamping device that releases when the time comes, the prior patent is to design a metal link chain formed by a series of friction elements on the clamping device, which has many elements and complex structure, and in the process of locking the rope, the rope needs to pass through multiple friction elements In order to be locked, it must slide on the rope for a long distance. In the rope locked area, it will cause a certain degree of panic to the user.

[0004] In addition, the Chinese invention patent with the application number 201610806762.X discloses a lifting integrated device used on the rope, which uses the clamping of the moving lock piece and the fixed lock piece to the rope when the load is used to fix the bottom plate and the cover plate. Tighten to lock the rope. When released, the handle makes the moving lock piece leave the fixed lock piece through the principle of leverage to relax the clamping force on the rope. At the same time, the direction of the force of the lever also straightens the originally curved rope, which also causes extreme Big safety hazard, in case the user feels panic when using it, instinctively press down on the handle, it will fall at the speed of free fall, resulting in dangerous consequences
