Description

An auxiliary tool for fastening screws of transmission towers

Technical field:

The invention relates to an auxiliary tool for fastening screws of transmission poles and towers, which belongs to the field of power system transmission line maintenance.

Background technique:

The assembly and maintenance of transmission line towers require repetitive screw fastening work. In the process of screw fastening, it often occurs that the bolt of the screw rotates together with the nut and cannot continue to be tightened. During the erection and maintenance of transmission line poles and towers, the screws on the main bars of the poles and towers are arranged in two or more rows in a regular shape, and the number of screws on a single main connection part can reach 40-50, which is labor-intensive and takes a long time. At present, generally adopt two wrenches to realize the fastening of screws, one wrench fixes the head of the bolt, and the other wrench tightens the nut, which is very inconvenient for workers working at heights.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a device with reasonable structure, convenient operation, time-saving and labor-saving, fast and effective screw fastening, which reduces the risk of high-altitude operations, improves work efficiency, and improves the reliability of power supply. Auxiliary tool for fastening screws of transmission towers.

The purpose of the present invention can be achieved through the following measures: an auxiliary tool for fastening the screws of transmission towers, which is characterized in that it includes a connecting rod rotating sleeve, and the connecting rod rotating sleeve is composed of a first connecting sleeve rod and a second connecting sleeve rod , the first connecting rod is composed of the first connecting rod body) and the plum blossom sleeve fixed connection, the plum blossom sleeve is a hollow cylinder with a double hexagon inside, and the second connecting rod is composed of the second connecting rod body and the double ring sleeve , the double-ring sleeve is a cylindrical sleeve whose outer wall is partially cut off from 1/3 height to 2/3 height of the 300° side wall. The inside of the cylinder can be rotated freely. The ends of the first connecting rod body and the second connecting rod body are provided with threads, respectively connected to the first threaded sleeve and the second threaded sleeve, and the first threaded sleeve is threadedly connected to one end of the first connecting rod. , the second threaded sleeve is threadedly connected to one end of the second connecting rod, the other end of the first connecting rod and the other end of the second connecting rod are respectively connected to a connecting rod collar, and each connecting rod collar is provided with a positive Inverting the switching controller, each connecting rod collar is embedded with a ratchet, and the thread direction at the end of the first connecting rod body and the second connecting rod body is opposite to the thread direction at one end of the first connecting rod and the second connecting rod.

Compared with the prior art, the present invention can produce the following positive effects: the present invention is developed for utilizing the characteristics that the connecting screws of the main material of the transmission line pole and tower are mostly double-row staggered arrangement, and can be fastened by the screw of the transmission line iron tower with more effective means. The bolts are fixed during the process, so that the screw fastening work can be completed in the shortest time. The invention adopts the design of adjustable length and adjustable angle for multiple parts, which can adapt to the fastening of screws in different parts of the iron tower, and the thickness of the sleeve wall is thin and there is no handle. It can realize the fixing of bolts, which solves the problem that the wrench cannot fix the bolts when the distance between the screws and the tower material is close. The number of fixing bolts is large, and at most three bolts can be fixed at the same time, which avoids the trouble of constant adjustment with the wrench. The three-point fixing method can make the bolts bear mutual force during the fastening process, and does not need to be fixed manually. With the help of the invention, the operator can use only one hand to force, which is convenient for the adjustment of the working posture in the high altitude, and is convenient for the operator. Maintain a comfortable working posture, reduce the risk of working at heights, improve the safety of operators working at heights, and have good stability. Improved work efficiency.

Due to the application of the present invention, it has played a great role in promoting the work efficiency of tower erection and maintenance of transmission lines, shortened the time of tower erection and maintenance, greatly reduced the construction period and power failure time, and improved the reliability of power supply sex. The present invention shortens the average time for fastening a screw from 90 seconds to 60 seconds. According to the calculation of 1000 screws in a base iron tower, the time saved in the screw tightening work of a base iron tower is:

1000pcs * (90 seconds - 60 seconds) = 30000 seconds ≈ 8.3 hours

Calculated on the basis of 50 towers for a transmission line, the construction period of a transmission line will be shortened:

8.3 hours * 50 basis ÷ 24 hours/day ≈ 17.2 days

Therefore, the present invention is reasonable in structure, easy to operate, saves physical strength, has strong practicability, objective safety benefits and economic benefits, and is suitable for large-scale use in the erection and maintenance of transmission line poles and towers. At the same time, it can be extended to other fields that require screw fastening and face the same problem.
