Abstract

The utility model provides a transmission line iron tower falling prevention device. A steel strand(2) is up and down and from left to right fixedly arranged on the body of the iron tower(1) of the utility model. Crimping is used for one end of the steel strand, a connection of UT cable clamp(3) is used for the other end and the distance between the steel strand the tower body is fixed by using an angle steel(4) and a U-shaped bolt(5) in the middle. The utility model overcomes the deficiency of no safety protection for the climbing of the iron tower in the repairing and maintenance of the existing transmission line, which can prevent the falling of the staff and protect the safety of the working staff in the occurrences of the accidents of empty treading and slip down etc in the climbing of the tower and process of mobility.

Description

The iron tower of power transmission line falling proof device

Technical field: the utility model belongs to iron tower of power transmission line and steps on tower safety guard technical field.

Background technology: in existing transmission line of electricity operation maintenance, service work; climb iron tower and carry out the groundwork that service work is the line work personnel; extension along with transmission line of electricity; the quantity of iron tower is more and more; aging circuit makes that to step on the tower service work more frequent, but at present in climbing the iron tower process, the staff is without any safety precautions; rely on the careful climbing of climbing personnel oneself fully, this situation has very big potential safety hazard.

Summary of the invention: the purpose of this utility model is climbed the defective that iron tower does not have safeguard protection in order to overcome to have now in the Maintenance of Electric Transmission Line maintenance just; when the operation personnel are climbing sky, sliding when fortuitous event such as falling appears stepping on and provide a kind of in iron tower and the moving process; prevention personnel tenesmus, the iron tower of power transmission line falling proof device of safeguard work personal security.

The purpose of this utility model is achieved by the following technical solution.

The iron tower of power transmission line falling proof device is set with steel strand wires from the bottom to top from left to right on iron tower, one of its steel strand wires adopt crimping, and the other end adopts the UT wire clamp to connect, the middle fixedly spacing of steel strand wires and body of the tower of angle steel and U-bolt that adopts.

The utility model crimp head is connected with iron tower with U-bolt by angle steel, and the UT wire clamp is connected with iron tower by angle steel, is fixed on the firm parts of iron tower.

Because this device is by being used with the speed difference protector that is connected on staff's health; in the process that the staff moves on Deng Ta and tower; when sky or sliding when fortuitous event such as falling appears stepping in the operator; the speed difference protector that is connected on the iron tower steel strand wires produces non-return effect when gliding; by speed difference protector fixing on the iron tower steel strand wires rapidly, reach the purpose of protection operating personnel personal safety.The simple and reliable practicality of the utility model apparatus structure, easy to operate, flexible, easily allow the operating personnel grasp use, have good safe value, economize, install easily, have versatility with material.

Further set forth the utility model content below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the utility model structural representation;

Fig. 2 is U type spiral shell and iron tower connection diagram;

Fig. 3 is that steel strand wires are by U-bolt and iron tower connection diagram;

Fig. 4 passes through UT wire clamp and U-bolt and iron tower connection diagram for steel strand wires.

The specific embodiment: from the bottom to top, be set with steel strand wires 2 from left to right on iron tower 1 body of the tower, one of its steel strand wires adopt crimping, and the other end adopts UT wire clamp 3 to connect, the middle fixedly spacing of steel strand wires and body of the tower of angle steel 4 and U-bolt 5 that adopts; Crimp head is connected with iron tower 1 with U-bolt 5 by angle steel, and the UT wire clamp is connected with iron tower by angle steel, is fixed on the firm parts of iron tower.

Steel strand wires 2 and being connected according to Fig. 1 mode of iron tower 1 are arranged connection, whole iron tower 1 body of the tower steel strand wires 2 from left to right, from the bottom to top around a circle, different local steel strand wires are adopted different connected modes with body of the tower, a is illustrated as according to Fig. 2 connected mode and connects among Fig. 1, b is illustrated as the connected mode that connects according to Fig. 3 connected mode among Fig. 1, and c is illustrated as the connected mode that connects according to Fig. 4 connected mode among Fig. 1.The utility model allows to be stepped on tower protection rope and climbs stroke in the iron tower to prolong the back fixing along stepping on the tower operating personnel, becomes the permanent tower protection rope of stepping on, to guarantee to step on tower operating personnel's safety.The utility model is through security evaluation, and this device is installed the back does not have other significantly newly-increased dangerous matter sources.
