Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to an auxiliary bracket for cable laying in coal mine transformation. Background Technique

[0002] During the power supply process of coal mines, cables need to be laid. Cables are usually similar to ropes formed by twisting several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The whole is wrapped with a highly insulating covering layer. Cables have the characteristics of internal power conduction and external insulation. During the cable laying process, brackets are generally needed for auxiliary support.

[0003] However, during the use of existing auxiliary brackets, it is very easy for the cable to rub against the bracket due to the staff dragging the cable, resulting in cable damage. And since the cable laying direction generally changes according to the situation in the tunnel during cable laying, and the existing cable brackets are generally perpendicular to the tunnel wall after installation. At the same time, after the cable brackets are installed, the angle of the brackets cannot be adjusted, which greatly increases the construction difficulty of cable laying. Summary of the Invention

[0004] The purpose of the utility model is to provide an auxiliary bracket for cable laying in coal mine transformation to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An auxiliary bracket for cable laying in coal mine transformation, including a mounting plate, multiple groups of first connecting plates are clamped on the mounting plate. One end of the first connecting plate is fixedly connected with a first connecting shaft. The end of the first connecting shaft far away from the first connecting plate is fixedly connected with a connecting sleeve. A number of limiting circular grooves are arranged on the outer wall of the connecting sleeve. One end of the connecting sleeve far away from the first connecting shaft is slidably connected with an adjusting column. An indentation groove is arranged on the outer wall of the adjusting column. A clamping button is fixedly connected inside the indentation groove through a telescopic spring. One end of the adjusting column far away from the connecting sleeve is fixedly connected with a first rotating shaft. The end of the first rotating shaft far away from the adjusting column is fixedly connected with a second connecting plate.

One end of the second gear is fixedly connected with a third rotating shaft. The third rotating shaft is fixedly connected with a support plate. The support plate is fixedly connected with a movable plate. The movable plate is fixedly connected with the second rotating shaft.

[0006] Preferably, multiple groups of mounting seats are fixedly connected to the support plate. Pulleys are symmetrically and fixedly connected in the sliding grooves of the mounting seats.

[0009] Preferably, a limiting plate is clamped at the upper end of the mounting plate, and the first connecting plate is evenly clamped with the limiting plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The cable is placed in the chute of the mounting base and contacts the pulley. When the cable is pulled, the pulley drives the cable to move, thus converting the traditional hard friction into rolling friction, thereby avoiding damage to the cable outer skin. After the cable is placed, the first gear is rotated to engage with the second gear, so that the movable plate rotates in the second connecting plate through the second rotating shaft, so that the support plate can be adjusted up and down in angle.
