Description

An anti-drop protection device for utility poles

technical field

The invention relates to an anti-fall protection device for electric poles.

Background technique

During the reconstruction of low-voltage lines, it was found that there are basically no reliable anchorage points for safety belts on the poles, especially in the erection of insulated wires. "Regulations: Any operation carried out at a height of 2 meters or more from the height datum shall be regarded as high-altitude operation. Safety belts must be used when working at heights. The use of safety belts must first follow the principle of "high hanging low use", that is, the suspension point of the safety belt should be higher than the personnel's working position, so as to play a protective role. The suspension of the safety belt must have a reliable anchor point, and it must be erected. When the cables are parallel, the cables are not easy to hang.

Contents of the invention

The purpose of the present invention is to provide an anti-drop protection device for utility poles, which can effectively solve the problem that there is no reliable safety belt suspension point for operation on the existing poles, and the problems that the cables are inconvenient to hang when erecting parallel cables.

In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical solutions: an electric pole fall protection device, including a left hoop and a right hoop, one side of the left hoop and one side of the right hoop rotate connection, the other side of the left hoop is provided with a left connecting plate, and the left groove is opened on the left connecting plate, and the other side of the right hoop is provided with a right connecting plate, and the right The connecting plate is rotatably connected with a rotating shaft, and a connecting rod whose outer end is inserted into the left groove is fixed on the rotating shaft. The connecting rod is provided with an external thread, and a nut is sleeved on the connecting rod. A hanging ring is fixed on the outer wall, a butterfly porcelain bottle is fixed on the outer wall of the right hoop, a fixing rod is arranged on the outer circumference of the right hoop, and the butterfly porcelain bottle is set on the fixing rod. The head of the fixed rod is provided with a locking ring for locking the butterfly porcelain bottle.

Preferably, two rotating rings on the same axis are fixed on the surface of the right connecting plate away from the left connecting plate. The right groove snaps into the left groove; it is convenient for the rotating shaft to rotate, and at the same time, it is convenient for the fastening and fixing of the connecting rod.

Preferably, one side of the left hoop and one side of the right hoop are rotatably connected through a hinge, which facilitates the rotational connection of the left and right hoops.

Preferably, the inner side walls of the left and right hoops are provided with non-slip linen; anti-slip treatment is performed to further ensure the safety of use.

Compared with the prior art, the advantages of the present invention are: the structure of the device is simple, easy to use, the operator can meet the operating specifications, and the personal safety of the operator can be ensured. The nut on the rod can be easily adjusted to eliminate the gap between the left and right hoops. The hanging ring is convenient for the operator to hang the safety rope. The butterfly porcelain bottle can be used to hang the cable when laying parallel cables, realizing multiple purposes.

Detailed ways

Referring to Fig. 1, it is an embodiment of an anti-drop protection device for utility poles of the present invention, a kind of anti-fall protection device for utility poles, comprising a left hoop 1 and a right hoop 2, one side of the left hoop 1 and the right hoop One side of the hoop 2 is rotationally connected by a hinge 13, and the inner sidewalls of the left hoop 1 and the right hoop 2 are provided with non-slip linen 14, and the linen 14 is used instead of rubber, mainly because the anti-skid effect of the linen 14 is good and The wear-resistant life is long, and the fixing of the linen 14 and the hoop is simpler than that of rubber. The other side of the left hoop 1 is provided with a left connecting plate 3, and the left connecting plate 3 is provided with an upward opening. The left groove 4, the other side of the right hoop 2 is provided with a right connecting plate 5, and a rotating shaft 6 is connected to the right connecting plate, and the outer end of the rotating shaft 6 is fixed to be inserted into the left groove 4. Connecting rod 7, two swivels 11 on the same axis are fixed on the surface of the right connecting plate 5 away from the left connecting plate 3, the two ends of the rotating shaft 6 are respectively located in a swivel 11, and the right connecting plate There is a right groove 12 on the top to facilitate the connecting rod 7 to snap into the left groove 4. The connecting rod 7 is provided with external threads, and the connecting rod 7 is covered with a nut 8. The outer wall of the left hoop 1 A hanging ring 9 is fixed on the top, a butterfly porcelain vase 10 is fixed on the outer wall of the right hoop 2, a fixed rod 15 is provided on the outer circumference of the right hoop 2, and the butterfly porcelain vase 10 is set on a fixed On the rod 15, the head of the fixed rod 15 is provided with a locking ring 16 for locking the butterfly porcelain bottle 10.

As shown in Figure 2, when using the device, clamp the device on the utility pole, make the left hoop 1 and the right hoop 2 hold the utility pole tightly, flip the connecting rod 7 into the left groove 4 and right groove 12, adjust The nut 8 on the connecting rod 7 reaches a suitable position, so that the left hoop 1 and the right hoop 2 can clamp the utility pole, and the safety belt of the operator can be hung on the hanging ring 9 of the left hoop 1, and the butterfly porcelain bottle 10 can replace the original pulley for parallel cable laying.
