technical field

The utility model belongs to line erection accessories, in particular to a cable fixing device.

Background technique

The power substation in the factory area of industrial and mining enterprises uses GIS combined electrical appliances. Due to the limitation of the site conditions of the factory area, the cable inlet and outlet are used. After the cable is drawn out from the power substation, it is laid along the iron frame of the iron tower to the 110KV transmission line at the top of the tower. Therefore, the stability of the connection between the cable and the tower transmission line becomes the key to the safe operation of the equipment. At present, a U-shaped card simple fixing device is used between the cable and the iron frame of the iron tower, and the cable is fixed on the iron frame by the U-shaped card. The existing problem is that the iron frame of the iron tower is made of angle steel. When fixing the U-shaped card, the operation is cumbersome, time-consuming, and the work efficiency is low; and the force of the U-shaped card is uneven. When the cable shakes, it is easy to cause the cable to loosen. The shape card slips, and the joints of the cables and the transmission lines are disconnected under force; at the same time, due to the limited number of iron frames of the iron tower, when multiple cables are erected, only a certain number of cables can be fixed on the iron frames, and other cables cannot be fixed. Between the iron tower and the power substation, the joints of cables and transmission lines are easily disconnected under force. The above two situations will lead to power interruption, affect the normal operation of power equipment, affect normal production, and even equipment damage, spare parts and spare parts The consumption is large, the maintenance cost increases, and when the cable falls off seriously, it will cause electric shock, and there are potential safety hazards.

The fixing device for the T-connection cable of the iron tower includes the cable and the iron tower. The iron tower is composed of an iron frame. It is characterized in that the device is composed of a fixing seat, a crosspiece and a U-shaped card. The two ends of the gear are respectively connected and fixed by fixing seats, and multiple cables drawn from the power transformer are respectively fixed on the crosspiece by U-shaped clips.

The utility model is further improved. The fixed seat is composed of a splint, a support and a cover plate. A connection hole, a support plate and a clamp are provided on the splint, and a connection hole is provided on the cover; the support is made of I-shaped steel. Two supporting rods are symmetrically arranged on the upper end surface, and through holes are set on the upper end surface and the lower end surface of the support respectively corresponding to the connecting holes of the splint and the connecting hole of the cover plate. It leans against the iron frame, the splint and the support are docked on both sides of the iron frame, and are fastened by bolts; the cover plate and the support are connected by bolts, and the crosspiece is set in the gap formed by the two support rods.

The utility model is further improved, the crosspiece is made of channel steel, the length of the channel steel is greater than the distance between the two fixed seats, and a through hole is opened in the channel steel channel, the diameter of the through hole is equivalent to the diameter of the U-shaped card, and the crosspiece The opening is facing inward, which is convenient for U-shaped card fixing.

The utility model is further improved, the length of the clamp is consistent with the width of the iron frame, the clamp forms a U shape, and the iron frame made of angle steel is inserted in the clamp.

The utility model is further improved. The length of the support rod is consistent with the width of the crosspiece. When installing, the crosspiece can be placed on the support rod to facilitate fixing the cover plate by bolts.

Compared with the existing technology, the advantage is that the concept is novel, the structure is simple and reasonable; the device adopts the fixed seat and the crosspiece, the operator can install and fix it conveniently and quickly, and the work efficiency is high; the cable is directly fixed on the horizontal crosspiece by the U-shaped card On the top, the force of the bolts at both ends of the U-shaped card is balanced on the crosspiece, so that the U-shaped card is not easy to slip, ensuring that multiple cables drawn from the power substation are safely and reliably fixed on the iron frame, and the power supply is stable and normal. Equipment damage is reduced, maintenance frequency is reduced, maintenance costs are reduced, and hidden dangers of electric shock that endanger people are eliminated.
