The transformer is usually set on a higher tower, and the maintenance work on the transformer belongs to the category of high-altitude operations. In the safety regulations for high-altitude operations in power systems, safety belts or safety ropes are required for all high-altitude operations that are 2m and above from the falling height datum to protect the operating safety of operators; safety ropes or safety belts are used It should be hung on a solid object or on a steel frame or wire rope specially used for seat belts, and should not be hung low or high.

The current patent name is a safety rope suspension device for transformers (patent number: 201320598361.1). Prevent the occurrence of illegal operations with low hanging and high use. However, in actual use, the connection between the support rod and the connecting seat is not firm, and problems such as rollover and rotation of the support rod often occur.

Utility model content

The technical problem to be solved by the utility model is to provide a suspension device that is applied to the transformer and is used for hanging the safety rope, and the support rod and the connecting seat are firmly connected, which can not only effectively ensure the safety of the workers, but also prevent low-hanging Occurrence of violations of rules and regulations.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The safety rope suspension device for transformers includes an insulating support rod and a pull ring for fixing the safety rope arranged on the upper part of the insulating support rod, and the bottom end of the insulating support rod is arranged on the transformer ring through a connecting seat; the connecting seat includes The square tube connecting piece made of thick square tube, the inner cavity of the square tube connecting piece is larger than the outer contour of the transformer ring, and the two side walls of the square tube connecting piece corresponding to the center hole of the lifting ring are relatively provided with holes for the bolts passing through the fixing ring. hole, and the opposite side walls of the other two sides of the square tube connector are respectively provided with a tightening mechanism for tightening the transformer ring; the wall thickness of the square tube connector is 120mm, and the top of the square tube connector is closed with a steel plate. The bottom end of the insulating support rod is fixedly connected on the steel plate, and it includes a diagonal support 5, and the two ends of the diagonal support 5 are respectively fixed on the support rod 1 and the connecting seat 3.

Several pull rings are evenly distributed from top to bottom on the upper part of the insulating support rod.

The pull ring is suspended on the insulating support rod through a hoop sleeved on the insulating support rod, and the hoop is riveted on the insulating support rod through screws.

The tightening mechanism includes a stud and an internal thread hole arranged on the side wall of the square tube connector to fit the stud.

Compared with prior art, the technological progress that the utility model obtains is:

The utility model has a simple structure, and when in use, the oblique support, the support rod and the connection seat form a triangle, so that the connection between the support rod and the connection seat is more fixed, and problems such as rollover and rotation of the support rod do not occur. The application of the utility model provides a fixed support for the suspension of the safety rope, which can not only effectively ensure the safety of the operators, avoid the phenomenon of falling from high altitudes, but also prevent the occurrence of illegal operations for low-hanging and high-level use.

Detailed ways

A safety rope suspension device for a transformer, its structure is shown in Figure 1, including an insulating support rod 1, the upper part of the insulating support rod is provided with a pull ring 2 for fixing the safety rope, and the bottom end of the insulating support rod 1 passes through the connecting seat 3 Set on the transformer lifting ring. An oblique support 5 is fixed between the insulating support rod 1 and the connecting base 3 .

The bottom view of the utility model connection seat 3 is as shown in Figure 2.

The connection seat includes a square tube connector 31 made of a thick square tube. The inner cavity of the square tube connector is larger than the outer contour of the transformer ring, so it is advisable to completely enclose the transformer ring. The two side walls of the square tube connector corresponding to the central hole of the suspension ring are provided with through holes 32 oppositely, which are used to pass through the bolts for fixing the suspension ring during use. The opposite side walls of the other two sides of the square tube connector 31 are respectively provided with a jacking mechanism, and the jacking mechanism includes a stud 34 and an internally threaded hole arranged on the side wall of the square tube connector to match the stud; It is used to tighten the outer wall of the transformer ring, so that the connecting seat is firmly positioned on the transformer ring and the top wall of the transformer box where the transformer ring is located. The top of the square tube connector adopts a steel plate 33 to seal the setting, and the bottom end of the insulating support rod 1 is fixedly connected to the steel plate 33. The wall thickness of the square pipe connector of the utility model is selected as 120mm to ensure that it has sufficient supporting force.

The upper part of the insulating support rod is evenly distributed with several pull rings from top to bottom. The pull ring 2 is suspended on the insulating support rod 1 through the hoop 4 set on the insulating support rod, and the hoop is riveted on the insulating support rod by screws, which is convenient for multiple people to work at the same time.

When the utility model is in use, first insert the lower opening of the square tube connector vertically into the transformer ring, then insert the bolt into the side wall of the square tube connector of the connecting seat, pass through the center hole of the ring, and insert the bolt from the square tube connector protrude from the opposite side wall of the square tube and fix it with nuts; secondly, tighten the studs 34 on the other two side walls of the square tube connector until the outer wall of the transformer lifting ring is tightened; finally, tie the safety rope of the operator to the pull ring Go to work. When multiple people are working, different safety ropes can be tied to different pull rings.
