Problems solved by technology

[0002] When someone falls into a deep well with a diameter of less than 50cm, it is difficult to rely on others to enter the well for rescue. Often the only thing to do is to dig out the deposits on the periphery of the well wall to reach the trapped person and then break through the wall to rescue the trapped person. This is laborious and time-consuming. Delayed the best time for rescue

Abstract

The invention discloses a lever linkage pull rod hook for small-bore deep well rescue. The lever linkage pull rod hook for small-bore deep well rescue is composed of a top control frame, a brake rod,a pull rod and a strain hook frame; a component for connecting the brake rod with the pull rod is arranged in the top control frame, a supporting rod for hooking dual armpits of a person falling a well is arranged in the strain hook frame, the brake rod and the pull rod are connected to the needed length one by one according to the depth of the person falling in the deep well in a well hole, the supporting rod in the strain hook frame is changed by the brake rod through a lever and a falchion-shaped component in the strain hook frame, when the supporting rod is not moved to the lower portionsof the armpits of the person falling the well, the supporting rod is in the hanging state, when the supporting rod reaches the needed position, through brake of a control frame lock buckle on the topcontrol frame, the brake rod descends to promote the supporting rod to be rotated to be in the horizontal state, the armpits of the person falling in the well are hooked, the lifting rescue can be implemented, the backward means that a person must go into the well for rescue or the well wall is dug for rescue is omitted, and the great convenience is created for related rescue work.

Description

Technical field: [0001] The invention relates to a pull-type hook, in particular to a lever-linked pull-rod hook for small-caliber deep well rescue. Background technique: [0002] When someone falls into a deep well with a diameter of less than 50cm, it is difficult to rely on others to enter the well for rescue. Often the only thing to do is to dig out the deposits on the periphery of the well wall to reach the trapped person and then break through the wall to rescue the trapped person.
