A shrapnel type iron tower climbing safety hook

Abstract

The invention discloses an elastic trip type iron tower climbing safety hook, which is characterized by comprising a left supporting arm and a right supporting arm, wherein the left supporting arm and the right supporting arm are distributed in a eudipleural manner; both the left supporting arm and the right supporting arm consist of vertical inner sections and vertical outer sections, of which the upper ends are connected together; two outer sections are connected into a whole through a transverse beam; the opposite surfaces of the two inner sections are connected with stop blocks, which extrude towards opposite sides, respectively; the stop blocks are connected with starting elastic trips; the lower ends of the stop blocks are provided with cushion blocks pressed on the inner sides of the starting elastic trips; the outer ends of the two cushion blocks are connected with transmission arms respectively; the outer ends of the two transmission arms are connected through an outer connecting beam; the middle parts of the two transmission arms are connected through a middle connecting beam; the middle part of the middle connecting beam is provided with a vertical arm; the upper end of the vertical arm is connected with the transverse beam in a hinging manner; joints among the upper ends of the inner sections and the outer sections are connected with lifting lugs. By using the elastic trip type iron tower climbing safety hook, a hanging-connection position is replaced without taking off the hook; a replacement gap is also defended; the real-time protection can be achieved; safety accidents caused when falling off occurs are reduced; the position is replaced with a small movement range; falling-off risks are lower.

Description

technical field [0001] The invention relates to safety protection equipment for climbers when climbing an iron tower, in particular to a shrapnel type iron tower climbing safety hook. Background technique [0002] my country has a vast territory, dense power transmission lines and high-level mobile communication networks, and power towers and mobile communication towers can be seen everywhere. One end of the safety rope should be hung on a fixed place on the iron tower, and the other end should be connected with the high-altitude workers to ensure the safety of the operation. This is only a safety protection after climbing the iron tower. The moving safety rope cannot be fixed at a fixed position, and the hook needs to be removed frequently to replace the mounting position. There is no protection in the replacement gap, and if it falls, it will cause a safety accident, and there is a height difference between the two positions before and after the replacement. Large up and dow...

[0002] my country has a vast territory, dense power transmission lines and high-level mobile communication networks, and power towers and mobile communication towers can be seen everywhere. One end of the safety rope should be hung on a fixed place on the iron tower, and the other end should be connected with the high-altitude workers to ensure the safety of the operation. This is only a safety protection after climbing the iron tower. The moving safety rope cannot be fixed at a fixed position, and the hook needs to be removed frequently to replace the mounting position. There is no protection in the replacement gap, and if it falls, it will cause a safety accident, and there is a height difference between the two positions before and after the replacement. Large up and down movements are also prone to accidents, especially when the operator is carrying accessories, the movements are more clumsy and the risk is higher. As an iron tower manufacturer, we have not had a good way to solve it before, and we need to further innovate to solve it
