Description

A kind of screw fastening tool for iron tower of transmission line

Technical field:

The utility model relates to a screw fastening tool for an iron tower of a power transmission line, which belongs to the field of power system transmission line maintenance.

Background technique:

In the process of assembling and overhauling transmission line iron towers, a lot of repetitive screw fastening work is required. In the process of screw fastening, it often occurs that the bolt rotates with the nut, and the head of the bolt needs to be fixed before continuing to tighten. At present, it is generally adopted to fix the head of the bolt and the nut with a wrench respectively, which uses many tools and requires both hands to operate. At the same time, due to the limited working space on the tower, it causes serious inconvenience to the work, reduces work efficiency, and increases the risk factor of operators. The position of the hole relative to the tower material may hinder the operation of the wrench, so that the wrench cannot fix the bolt head.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a flexible, simple operation, shorten the time of screw fastening, improve the efficiency of pole tower assembly, improve the safety of high-altitude operations, and save the physical strength of operators. , A power transmission line iron tower screw fastening tool that reduces the number of tools carried by operators.

The purpose of this utility model can be achieved through the following measures: a power transmission line iron tower screw fastening tool, which is characterized in that it includes a stop wrench, the stop wrench is connected to the connecting plate through a connecting rod, and a locking wrench is nested on the connecting plate , the locking wrench is nested in the connecting plate through the slot on the upper part of the connecting plate, the locking wrench is connected with the ratchet wrench, and both the anti-rotation wrench and the locking wrench use a ring wrench.

In order to further realize the purpose of the utility model, the distance between the anti-rotation wrench and the clamping groove is 100mm.

Compared with the prior art, the utility model can produce the following positive effects: the utility model can improve the convenience of screw fastening, shorten the time of screw fastening, further shorten the time of tower erection and maintenance, and improve the efficiency of pole tower erection . The utility model only uses one tool to realize the fastening of screws, reduces the number of tools that operators need to carry when climbing poles and towers, simplifies the operation steps of operators for high-altitude operations, and reduces the risk of operators for high-altitude operations to a certain extent. During the fastening process, the operator maintains a comfortable working posture, improves the safety of high-altitude operations, and saves the physical strength of the operator. Compared with the realization of screw fastening by using two spanners, the utility model has the characteristics of good flexibility and simple operation.

The application of the utility model greatly promotes the work efficiency of tower erection and maintenance of transmission lines, shortens the time of tower erection and maintenance, greatly reduces the construction period and power failure time, and improves the reliability of power supply sex. The utility model shortens the average time of fastening a screw from 90 seconds to 50 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 - 65 seconds) = 25000 seconds ≈ 6.94 hours

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

6.94 hours * 50 basis ÷ 24 hours/day ≈ 14.46 days

Therefore, the novel transmission line iron tower screw fastening tool with reasonable structure, convenient operation and energy saving 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.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

FIG. 2 is a side view of position A in FIG. 1 .

The specific embodiment: the specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing:

Embodiment: A power transmission line iron tower screw fastening tool (see Fig. 1, Fig. 2), which includes a stop wrench 1 to prevent the bolt from rotating when the screw is fastened. The anti-rotation wrench 1 is connected with the connecting plate 4 through the connecting rod 5, and the bolt 6 is used to lock the anti-rotating wrench 1 and the connecting rod 5; Riveted to secure. The upper part of the connecting plate 4 is nested with a locking wrench 2, and the locking wrench 2 is nested in the connecting plate 4 through the slot 8 on the upper part of the connecting plate 4. The locking wrench 2 can rotate and move left and right, so that the stop wrench can be adjusted at will. 1. The distance between the locking wrench and 2. The purpose of screw tightening. The distance between the anti-rotation wrench 1 and the slot 8 is 100mm, that is, the moving distance of the locking wrench 2 can reach 100mm, which is greater than the screw length of all tower bolts. The locking wrench 2 is connected to the ratchet wrench 3, and the locking wrench 2 and the ratchet wrench 3 are welded and fixed by the third connection part 9, and the ratchet wrench 3 can be adjusted to realize forward rotation and reverse rotation. Both the anti-rotation wrench 1 and the lock wrench 2 use a torx socket wrench, as shown in Figure 2, which can ensure that they can be tightly fastened on the hexagonal bolt or hexagonal nut from all angles, so that the tool can be easily clamped on the screw rod. By adjusting the lock Tighten the position of the wrench 2 so that the anti-rotation wrench 1 fits on the head of the bolt, and the locking wrench 2 fits closely on the nut. Turn the ratchet wrench 3, and the locking wrench 2 drives the nut to move continuously on the screw rod. , when the screw is tightened, move to the direction of the anti-rotation wrench 1, and when it is loose, move to the direction of the card slot 8, and finally complete the screw tightening and loosening work.
