[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. At the same time, it can be understood as power transmission and transformation expansion engineering. In the process of power engineering construction, the laying of cables and wires is indispensable. When laying the wires, in order to tighten the cables and wires, a tightening device for power engineering construction, namely a tightener, is required.
[0003] The existing tightening device for power engineering construction usually has a ratchet on one side that cooperates with the hand lever to rotate to tighten the traction belt. There is a problem in this. If the ratchet diameter is set too small, the personnel need to rotate the hand lever multiple times to tighten the traction belt, which is troublesome to operate and has low work efficiency. If the ratchet is set too large, as the traction belt becomes tighter and tighter, the force required for the personnel to hold the hand lever to rotate will become greater and greater. For personnel with insufficient strength, they may not be able to completely tighten the cables and wires. Therefore, they cannot quickly, efficiently and labor-savingly tighten the cables and wires. In view of this, we propose a tightening device for power engineering construction. Utility Model Content

At this time, the fourth roller stops rotating and drives the first roller to stop rotating. At this time, the released length of the traction webbing is also consistent with the length released before the limiting webbing, so the relaxation of the tightened cable and wire can be accurately controlled.

At this time, the fourth roller 905 will also rotate accordingly, and the limiting webbing 11 will be retracted during the rotation process until the limiting webbing 11 is in a taut state. At this time, the fourth roller 905 stops rotating and drives the first roller 2 to stop rotating. At this time, the release length of the traction webbing 4 is also consistent with the length of the limiting webbing 11 released before, so it can be In order to achieve precise control of the relaxation of the cable and wire after tightening; specifically, two groups of symmetrical limit disks 906 are arranged on the fourth roller 905, and the limit webbing 11 is located between the two groups of limit disks 906, and the limit disks 906 have a limiting effect on the limit webbing 11 to avoid deviation when the limit webbing 11 is wound and stacked; further, a Velcro thorn surface is arranged at the bottom of the free end of the limit webbing 11, and a Velcro fur surface is arranged on the top surface of the free end of the limit webbing 11, and the Velcro thorn surface and the Velcro fur surface are arranged laterally separately.

This structure is the same as the speed change structure, which can achieve the effect of labor saving, and the larger the diameter of the large toothed disc 901 and the smaller the diameter of the small toothed disc 903, the more labor saving, so it can be ensured that the personnel can complete the tightening of the traction webbing 4 without using too much force, that is, the tightening operation of the cable wire can be completed;
[0031] Finally, if the cables and wires are over-tightened and need to be loosened to a certain extent, the limiting webbing 11 can be directly released to an appropriate length, and the released length of the limiting webbing 11 can be controlled by a scale. Then, the hanging hole at the free end of the limiting webbing 11 is buckled with the third anti-detachment hook 12. After the personnel releases the hand lever 7, the traction webbing 4 will be automatically pulled out under the action of the gravity of the cables and wires. At this time, the fourth roller 905 will also rotate accordingly, and the limiting webbing 11 will be reeled in during the rotation until the limiting webbing 11 is in a taut state. At this time, the fourth roller 905 stops rotating and drives the first roller 2 to stop rotating.
