Lifting equipment based on combination of triangular support and ratchet wheel

Abstract

The invention discloses hoisting equipment based on combination of a triangular support and a ratchet wheel. The hoisting equipment based on combination of the triangular support and the ratchet wheel comprises a bearing disc, a positioning telescopic rod and a framework suspension clamp, a hanging ring is fixedly installed in the center of the bottom of the bearing disc, the top of the bearing disc is trisected in the axial direction, ratchet wheels are arranged at the equally-divided positions, and positioning telescopic rods are installed through the ratchet wheels. One end of the positioning telescopic rod is rotationally connected with the bearing disc through a ratchet wheel in the mode that the rotation angle can be adjusted, and a framework hanging clamp is installed at the other end of the positioning telescopic rod. The hoisting equipment based on the combination of the triangular support and the ratchet wheel can be used as a safety belt hanging point for high-place operation and can also be used as a triangular support; the hoisting equipment based on the combination of the triangular support and the ratchet wheel can be mounted in any terrain in the complex field terrain and during high-altitude operation, provides support for hanging a safety belt, bears the force generated by falling of a human body, avoids the risk of falling from a high place, and achieves the purpose of safe and efficient operation.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a hoisting equipment based on the combination of a triangular support and a ratchet. Background technique [0002] The current work on the equipment structure in the substation often faces a difficulty, that is, the safety belt safety rope cannot be hung at a stable position higher than the work interface when working at heights, which neither meets the requirements of relevant safety regulations, but also causes problems in the work. hidden dangers. In response to this problem, the main solution at present is to erect an insulating rod on the ground, and the bottom of the insulating rod is fixed to the ground with a rectangular plane, or the bottom is fixed with a fork to make a high-point suspension safety belt. There are two major problems in this method. One is that the operating height of the equipment involved currently ranges from 2m to 5m, and the length of the insulati...

Problems solved by technology

There are two major problems in this method. One is that the working height of the equipment involved currently ranges from 2m to 5m, and the length of the insulating pole is limited, which cannot meet the requirements. If a long pole is used, it will be more difficult to carry

Second, at present, the support point of the upright insulation pole is mainly in the rectangular plane or clamping fork structure at the bottom of the insulation pole. If the risk of falling from a height does occur, this structure is difficult to bear the force generated by the human body falling, and there are potential safety hazards
