Description

An insulator nut tightener

technical field

The utility model relates to the field of electric power transmission construction engineering, in particular to a nut fastening device in a high-voltage power grid. the

Background technique

Slanted or column insulators on high-voltage lines are generally fixed by high-voltage nuts. Due to the long-term use process, the high-voltage nut is easy to loosen, causing the insulator bottle to be skewed. If it is not handled in time, the insulator will fall off and cause line failure.

At present, there are many cases in the distribution network that the insulator bottle body is skewed due to the loosening of the high-voltage nut. The measures taken are to carry out rectification in combination with the power outage. Due to the limitation of the power outage range, this measure can only complete the adjustment of the bottle body within the power outage range. The amount is small and it cannot be guaranteed that all rectifications will be completed within one overhaul cycle. The second measure is to use the insulated arm truck to carry out live work to adjust the insulator bottle body. Due to the heavy workload of each operation, the labor time is more; due to the actual geographical location, the insulated arm truck cannot be close to the high-voltage line in many cases. Unable to complete task.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the utility model comprises a sleeve 1, several insulating rods and a ratchet wrench 3 connected in sequence. The sleeve 1 is a hollow structure, and the shape inside the sleeve 1 corresponds to the bottom nut of the insulator. One end of the upper insulating rod 21 connected with the sleeve 1 is a protruding part 4, and the shape of the protruding part 4 corresponds to the shape inside the sleeve. The two insulating rods are connected through the plug-in part 5 provided at one end of the insulating rod. The plug-in part 5 is cylindrical, and semicircular protrusions are respectively provided on both sides corresponding to the curved surface for fixing the two insulating rods. pole. There is a groove corresponding to the ratchet wrench 3 at the bottom of the lower insulating rod 22 of the last joint. The lower insulating rod 22 is connected with the ratchet wrench 3 by inserting. The bottom nut of the insulator is put on the sleeve 1, the upper insulating rod 21 is inserted into the sleeve 1, and the ratchet wrench 3 rotates left and right to drive the insulating rod, the sleeve 1 and the insulator nut to tighten and loosen.

The sleeve 1 can be set into different models according to the size of the insulator nut. The number of the insulating rods is generally 4-5 sections, and the length of each insulating rod is 1.5m.

The ratchet wrench 3 has a rotating pointer, which rotates to the left to loosen the nut, and rotates to the right to tighten the nut.

The working process of the present utility model is described further below:

During construction, select the sleeve 1 corresponding to the nut to be installed on the front end of the upper insulating rod 21, select different numbers of insulating rods according to the site conditions, and install the ratchet wrench 3 on the end of the bottom section of the insulating rod. Align the sleeve 1 with the loose nut (if the nut is lost, put the nut to be installed in the sleeve and align it with the screw on the insulator). When operating by one person: the operator holds the insulating rod with one hand and turns the ratchet wrench with the other until the nut is tightened. When the pole tower is very high and the number of insulating rods used is large, two people are required to operate, one person holds the insulating rod at an appropriate position, and the other rotates the ratchet wrench until the nut is tightened.
