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.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a 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. A powerful auxiliary tool for fastening the screws of transmission towers.

The purpose of this utility model can be achieved through the following measures: an auxiliary tool for fastening the screws of transmission poles and towers, which is characterized in that it includes a connecting rod rotating sleeve, and the connecting rod rotating sleeve is composed of the first connecting sleeve rod and the second connecting sleeve rod The first connecting rod is composed of the first connecting rod body) and the plum blossom sleeve fixedly connected, the plum blossom sleeve is a hollow cylinder with a double hexagon inside, and the second connecting rod is connected by the second connecting rod body and the double ring sleeve Composition, 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 double-ring sleeve is fixedly connected with the second connecting rod, and the plum blossom sleeve is set on the double ring The sleeve is inside and can rotate 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 the first connecting rod. One end, 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 Forward and reverse switching controller, a ratchet is embedded in each connecting rod collar, the thread direction of the ends of the first connecting rod body and the second connecting rod body is opposite to the thread direction of one end of the first connecting rod and the second connecting rod.

Compared with the prior art, the utility model can produce the following positive effects: the utility model is developed for utilizing the characteristics that the connecting screws of the main material of the transmission line tower are mostly double-row staggered arrangement, and the transmission line iron tower screw is tightened by more effective means. The bolts are fixed during the fastening process, so that the fastening of the screws can be completed in the shortest time. The utility model 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, there is no handle, and the distance between the head of the bolt and the tower material is close It can also 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. There are a large number of fixing bolts, and a maximum of three bolts can be fixed at the same time, avoiding 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 utility model, the operator can use only one hand to force, which is convenient for the adjustment of the working posture in the high altitude and convenient for the operation. Personnel maintain a comfortable working posture, which reduces the risk of high-altitude operations, improves the safety of operators for high-altitude operations, and has good stability. Improved work efficiency.

Due to the application of the utility model, it has played a great role in promoting the efficiency of the erection and maintenance of transmission line towers, shortened the time for erection and maintenance of poles and towers, greatly reduced the construction period and power failure time, and improved the efficiency of power supply. reliability. The utility model shortens the average time of 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 fastening 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 utility model 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.
