Description

Hang some shedding staple bolt for split pin

Technical Field

The utility model belongs to the technical field of mechanical connectors, and particularly relates to an anti-falling hoop for a hanging point split pin.

Background

The split pin is used for preventing looseness of threaded connection. After the nut is screwed down, the cotter pin is inserted into the nut groove and the bolt tail hole, and the cotter pin tail is pulled open to prevent the relative rotation of the nut and the bolt. The cotter pin is a metal hardware, commonly known as a spring pin. In the electric power circuit, the existence of the split pin plays a key role in preventing the hanging point link hardware from falling off. In the daily construction maintenance and the inspection and overhaul work of the power line, the inspection of the opening pin of the hanging point is very important. Due to the fact that the types and the shapes of the split pins are different, the daily overhauling and maintenance difficulty is high. Once the cotter pin of the hanging point falls off, the overhead line is disconnected, and accidents such as line brake adjustment, fire, personal electric shock and the like are caused. The wire is more prevented from falling off when the wire is used for power transmission lines crossing railways, highways, rivers, valleys, forests and farming, livestock raising and densely populated areas.

The staple bolt is the metal connecting piece that prevents the split pin and drop, and the split pin of a model matches the staple bolt of a structure. Currently, the hanging point split pin used on the upper portion of the insulated terminal is a pin mounted inside the recess of the hanging head.

At present, the electric power circuit hanging point cotter pin has the following defects: 1. the types of the opening pins are different, and the daily inspection and maintenance difficulty is high; 2. the split pin is easy to fall off due to structural design defects; 3. the protection function is not provided, and personal and equipment accidents such as wire falling are easy to happen.

Taking actual engineering as a case, at present, a power supply company in Ling-hill county currently has 1271 base of 35KV power transmission lines, wherein the 1271 base spans 42 bases of forests, 18 bases of railways, 7 bases of rivers, 92 bases of highways and 84 bases of houses and densely populated areas. The 10KV distribution line 13252 foundation, wherein the foundation spans forest 274, railway 22, river 49, road 150, house and densely populated area 1846 and the foundation of 380V rural power grid line 27359, wherein the foundation spans forest 46, road 223, river 68 and house and densely populated area 5846. The base number of the electric pole 8767 base needs to be installed on the circuit, and 52602 sets are needed for the whole circuit according to calculation that 6 sets of cotter pins and hoops need to be installed on one base electric pole.

2445 base of power supply company line transformation, 61 station transformation and rectification, 824 damaged open pins of various types of hanging points in Ling-Tu county in 2020; indirectly connected with economic loss 94681 yuan. The hanging point opening pin is small but brings huge economic loss.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model provides the anti-falling hoop for the cotter pin at the hanging point, which solves the problems that the prior cotter pin is difficult to inspect and maintain and is easy to fall off to cause accidents.

The utility model is realized in this way, a hang some shedding pin with anti-drop staple bolt, its characteristic is: including left hoop body and right hoop body, the both ends of left side hoop body are equipped with left handle and hole, the centre inboard of left side hoop body is equipped with the end cap, the both ends of right side hoop body be equipped with left handle and hole one-to-one the right handle close the hole, the middle part of right side hoop body is equipped with the perforation that combines with the split pin, left side hoop body and right hoop body are through lining up the bolt and nut subassembly in left side handle close hole and right handle and hole is fixed.

In the above technical solution, preferably, the left hoop body is a linear metal plate, and the right hoop body is an arc metal plate.

The utility model has the advantages and technical effects that:

1. the universality is strong, and the daily inspection and maintenance are convenient. The hoop structure in the utility model is optimized. Compared with the traditional hoop structure, the left hoop body in the hoop is provided with the plug which is in clearance combination with the end part of the cotter pin, the right solid body is provided with the through hole which is in combination with the end part of the cotter pin pulling pin, and the hoop is not limited by the shape of the cotter pin and can be suitable for cotter pins with various shapes. Aiming at the current non-uniform opening pin models, the corresponding anchor ear is required to be selected according to the pins of different models during installation, and a large amount of manpower and financial resources are wasted. In the investigation in earlier stage, the model of reply current opening pin carries out redesign and reforms transform the structure of staple bolt, according to the staple bolt with hang some opening pin's internal clearance, the anticreep function of adjustment end cap to further adjustment overall modeling lets it make beautifully and practical and combine together.

2. The installation effectiveness is high, and staple bolt end cap combines with the tip clearance of split pin, and through promoting left hoop body, the volume realizes that split pin tip opens the locking fast. The quick mounting operation of one second without any auxiliary tool is realized.

3. Anti-drop, the security is high, avoids because of the accident that the split pin drops and causes. When the plug of the left hoop body is installed in place, the split pin is tightly combined with the connecting hardware fitting, and meanwhile, the left hoop body and the right hoop body are combined together through the bolt and nut assembly, so that the anti-falling function is achieved.
