Abstract

A high-altitude human body protection tracking block, the invention relates to the field of block machinery, which mainly includes: a pulley frame (1), a small pulley (2) and a large pulley (7); the middle part of the pulley frame (1) is fixed with a recovery device ( 6). The beneficial effects of the present invention are: when carrying out high-altitude operations, with the cooperation of the staff under the tower, especially when the number of broken wires is unknown, the use of high-altitude human body protection tracking tackle can reduce the load-bearing of the wires, and prevent the occurrence of problems caused by the staff and the carrying tools. Excessive weight will cause aggravated wire damage and breakage.

Description

A high-altitude human body protection tracking tackle

1. Technical field

The invention relates to the field of tackle machinery, in particular to a high-altitude human protection tracking tackle.

2. Background technology

Because transmission line equipment is often affected by severe weather such as strong winds, rain, snow, and lightning strikes during operation, there will be pollution flashover and zero-value damage of insulators, broken strands of wires, hanging foreign objects, and the separation and damage of multi-split wire spacers. and other problems; and when repairing the defects on the above-mentioned wires, the maintenance personnel can only use simple safety belt protection. Leading to high-altitude fall; as large-scale machinery violates regulations and collides with wires, the number of accidents such as fault tripping, wire breakage, and loose strands increases, and the repair tasks for repairing wires increase accordingly; on the other hand, when installing accessories on new lines, large It is difficult for some construction workers to move and work on the single-split conductor, and their balance ability is also poor, and it is easy for the seat belt to "hang upside down" on the conductor;

In the new employee skill assessment project "750kV Transmission Line Alignment", most of the new employees showed strong fear. The high-altitude human body protection tracking tackle can eliminate the fear of high altitude and play a great role in preventing the staff from falling. It is a device that protects and tracks movement at all times by taking advantage of the overhead ground wire's "high residence".

3. Contents of the invention

In view of the above problems, the present invention provides a high-altitude human body protection tracking block, which is characterized in that: the upper part of the pulley frame (1) is provided with a shaft A (16), the inner side of the small pulley (2) is provided with a bearing A (4), and the small pulley (2) and the bearing A (4) are sleeved on the shaft A (16), and the small pulley (2) on one side of the bearing A (4) is also provided with a bearing cover (3), and the two sides of the bearing A (4) Shaft A (16) is provided with shaft sleeve A (5); the lower part of the pulley frame (1) is provided with shaft B (10), and the inner side of the large pulley (7) is provided with bearing B (8), and the large pulley (7) The bearing B (8) is sleeved on the shaft B (10), and a bearing cover is also provided on the large pulley (7) on one side of the bearing (8), and a bearing cover is provided on the shaft B (10) on both sides of the bearing B (8). Axle sleeve B (9) is arranged, and the small pulley (2) and the large pulley (7) on one side of the pulley frame (1) are also provided with hanging wire openings, and the lower end of the connecting plate (13) is passed through a flat head screw (11) and a nut (12) is fixedly connected with the lower end of the wire hanging port, and the upper end of the connecting plate (13) is fixedly connected with the upper end of the wire hanging port through a screw (14) and a washer (15); device (6), the recovering device (6) is rectangular, and one end is provided with a round hole.

The beneficial effects of the present invention are: the high-altitude human body protection tracking block is another reliable safety protection measure in addition to the safety belt and the backup protection rope, and is mainly used for the high-altitude transposition of the workers; the high-altitude human body protection tracking block is controlled by the ground cooperation personnel. , always keep the rope under force, and protect the operators at all times. When the ground coordinators find problems that the high-altitude workers have not discovered, the ground coordinators can remind the high-altitude workers by applying force to the rope; the high-altitude human body protection tracking tackle is installed on the overhead ground The pulleys on the line are light and flexible, and can move with the operators. They are located above the operators to improve the safety of protection; when performing high-altitude operations, use high-altitude human body protection with the cooperation of the staff under the tower, especially when the number of broken strands of the wire is unknown. The tracking block can reduce the load-bearing of the wire, and prevent the damage and breakage of the aggravated wire due to the overweight of the staff and the carrying tool.
