Embodiment 1

[0023] Such as figure 1 As shown, the multi-purpose insulating pull rod includes a rod body 1 and a pull rod head 2. One end of the rod body 1 is an insulating handle, and the other end of the rod body 1 is provided with a groove 3. The groove 3 is a through groove, and an elastic gasket is arranged in the groove 3. , the connecting end of the tie rod head 2 is provided with a protrusion 5 corresponding to the groove, the protrusion is inserted into the groove, the width of the protrusion is smaller than the width of the groove, the installation combination length of the groove and the protrusion is 100mm, and the pin 4 wears The rod body and the rod head are fixed through grooves and protrusions.

Embodiment 2

[0025] Such as figure 2 As shown, the protrusion is inserted into the groove, and the width of the protrusion is greater than the width of the groove. Other structure embodiment 1.

[0026] The drawbar head includes a variety of operation ends such as hacksaw head, standard head, blade head, clip head and nuclear phase head.

[0027] Practical application test demonstration: through the field operation test, each tie rod head is strong and practical, meets the requirements of the field, and meets the provisions of "personnel, trees, ropes and wires should be kept in line with the provisions of Table 5-1" stipulated in the "Safety Work Regulations for Power Lines". The safety requirements of "safe distance" eliminate the potential safety hazard of personal electric shock.

Abstract

The invention relates to a multipurpose insulation pull bar including a bar body and pull bar heads, one end of the bar body is provided with an insulation handle, the other end of the bar body is provided with a groove, the connecting end of each pull bar head is provided with a protrusion corresponding to the groove, the protrusion is inserted into the groove, and a pin penetrates through the groove and the protrusion to fix the bar body and the corresponding pull bar head. By means of the insertion structure of the groove and the protrusion and the movable connection of the pin, different pull bar heads can be replaced based on different place and uses, and one operation rod is provided with a plurality of pull bar heads, the cost is saved, and the carrying is convenient.

Description

technical field [0001] The invention relates to a power line safety tool, in particular to a multi-purpose insulating pull rod, which is suitable for 0.4-10kv lines, has multiple purposes, can realize convenient and quick replacement of working parts, and is suitable for different line operation functions. Background technique [0002] In the process of 10kV-0.4KV power line operation, the insulating pull rod is an indispensable safety tool, and it is a necessary tool for pulling and closing the line switchgear to ensure the personal safety of the operator. There are strict regulations on the use requirements of insulating tie rods. On the one hand, the insulation performance, strength and protection performance of the pull rod itself should meet the safety equipment test standards. On the other hand, the operation process complies with the provisions of the "Power Line Safety Work Regulations". During the inspection and operation of the 10kV power distribution overhead lin...
