Abstract

The utility model discloses an anti-falling safe hook, which comprises a U-shaped hook body (2) with a gate (1), wherein one end of the gate (1) is movably connected with the tail end of the hook body (2) through a rotating pin (3), and a return spring (4) is arranged on the rotating pin (3). The anti-falling safe hook is characterized in that: the tail end of the hook body (2) is provided with a hollow operating rod (5) fixedly connected with the tail end, and the joint of the hollow operating rod (5) and the tail end of the hook body (2) is provided with a connecting ring (6). The anti-falling safe hook has the advantages of simple structure and simple and convenient operation; meanwhile, an ultrahigh-voltage iron tower can be climbed by adopting the hook; and in the hook, only the opening size of the hook body is increased, the length of the hook body is prolonged and a gear of the body is increased, so the weight of the hook body is reduced.

Description

Anti-fall safety hook

technical field

The utility model relates to maintenance and climbing equipment for a grid iron tower, in particular to a safety hook for preventing falling. the

Background technique

At present, the anti-falling safety hook used on the power grid transmission line iron tower includes a hook body and a gate. One end of the gate is movably connected with the tail end of the hook body through a rotating pin, and a return torsion spring is arranged on the rotating pin. Maintenance personnel rely on the anti-fall safety hook to climb the iron tower. However, due to the limited length of the hook body and the excessive distance between the upper and lower tower sections of the existing UHV iron tower, maintenance personnel are climbing. The first person who went up the tower and the last person who went down the tower failed to use the hook to arrange the main rope, resulting in the ineffective use of the anti-fall safety hook. The opening diameter of the fall safety hook is too small, usually 11.5cm, which prevents the fall safety hook from hanging on the steel bar. In order to solve this problem, the technician proposes to increase the size of the fall safety hook, but the result is that the fall safety The weight of the hook is relatively large, and the operation is more inconvenient. the

Utility model content

The purpose of the utility model is to provide an anti-falling safety hook capable of climbing UHV iron towers. the

The purpose of this utility model is achieved through such a technical solution. A safety hook for anti-falling includes a U-shaped hook body with a gate. A return torsion spring is arranged on the pin, a hollow operating rod fixedly connected with the tail end is provided at the tail end of the hook body, and a connecting ring is arranged at the joint between the hollow operating rod and the tail end of the hook body. the

A pull rope passing through the hollow operating rod is arranged inside the hollow operating rod, one end of the pulling rope is fixedly connected with a pin arranged on the tail end of the gate, and the other end of the pulling rope is close to the tail end of the hollow operating rod. Set the limit block. the

In order to facilitate the quick return of the gate, a return tension spring integrated with the stay cord is arranged on the stay cord. the

In order to hang the hook body on the steel bar of the UHV iron tower, the opening of the hook body is 16cm-18cm. the

In order to make the length of the hook body long enough for climbers to climb conveniently, the length of the hollow operating rod is 1.8m-2.3m. the

Due to the adoption of the above technical solution, the utility model has the advantages of simple structure and easy operation. At the same time, the hook can not only climb the UHV iron tower, but also the hook only increases the opening size of the hook body and extends the length of the hook. The length of the body without increasing the size of the body makes the weight of the hook body lighter. the

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail, but the utility model is not limited to these implementation modes, and any improvement or substitution on the basic spirit of this embodiment still belongs to the claims of the utility model Scope of protection claimed. the

Embodiment 1: As shown in Figure 1, a safety hook for anti-falling includes a U-shaped hook body 2 with a gate 1, and one end of the gate 1 is connected to the rear end of the hook body 2 through a rotating pin 3. The turning pin 3 is provided with a return torsion spring 4, and the tail end of the hook body 2 is provided with a hollow operating rod 5 fixedly connected with the tail end, and a connecting ring is arranged at the connection between the hollow operating rod 5 and the tail end of the hook body 2. 6. the

Inside the hollow operating rod 5 is provided with a stay cord 7 passing through the hollow operating rod 5, one end of the stay cord 7 is fixedly connected with a pin 8 arranged on the tail end of the gate 1, and the other end of the stay cord 7 is A limit block 9 is arranged near the tail end of the hollow operating rod 5 . The return tension spring 10 integrated with the stay cord 7 is arranged on the stay cord 7 . Wherein, the opening of the hook body 2 is 16cm-18cm, and the length of the hollow operating rod 5 is 1.8m-2.3m. the

The utility model is used in this way: firstly tie the main rope on the connecting ring 6, then pull the stay rope 7, the stay rope 7 drives the pin 8 to open the gate 1, and then push the limit block 9 on the hollow operating rod 5 Tail end, make gate 1 be in open state all the time, hook body 2 is hung on the angle steel of pole tower again, unclamp stop block 9, under the effect of return extension spring 10, gate 1 is closed, just can climb like this. When climbing to the hanging position of the hook body 2, first put on the safety belt, take off the hook body 2 and then hang it upwards, and then take off the safety belt after hanging it, and then continue climbing to reach the operation point, and put the anti-falling The safety hook can be hung on the firm and reliable components of the iron tower at the operation point. The lower tower operation is the same as the upper tower operation, and will not be repeated here. the

The size of the opening of the hook body 2 and the length of the hollow operating rod 5 can also be set according to actual needs. the
