Description

Cable Pulling Device

technical field

The utility model belongs to the field of electric equipment manufacturing, in particular to a cable pulling device for laying cables.

Background technique

With the development of society, people's demand for electricity is increasing, and at the same time, they also put forward higher requirements for the beauty of the environment. Due to the high reliability of cable power supply, less impact on the city environment, and the large capacitance, which can improve line power and other advantages, it is used more and more in power system lines. However, in the traditional cable laying process, construction personnel are required to use manpower to drag the cable. Because the cable is quite heavy and heavy, there is a lot of friction with the cable tube or the ground during the dragging process, so the cable dragging efficiency It is very low, and when the construction environment in some places is harsh and the site for cable laying is complicated, such as soil slopes, muddy ground, bushes, etc., the construction workers cannot carry the cables at all, which affects the construction progress and sometimes affects the personal safety of the construction workers. Safety.

Therefore, if a device is manufactured that can replace the problem of construction workers dragging the cable by manpower during the cable laying process, it can greatly facilitate the cable laying work, improve production efficiency and construction quality, and ensure construction safety.

Utility model content

The technical problem to be solved by the utility model is how to replace the construction personnel to drag the cable by manpower during the cable laying process, and provide a cable pulling device that can pull the cable during the cable laying process.

In order to solve the above-mentioned technical problems, the utility model provides a cable pulling device, which includes a generator and a motor. The generator can supply power to the motor at any time in the workplace. During the process, the cable was forced to drag because it got stuck in the middle, so that the cable was dragged and damaged. The torque motor is connected with the torque motor controller, and the torque motor controller can be used to achieve stepless speed regulation, and the speed can be adjusted freely, so that the range and precision can be controlled. The torque motor is connected by a chain to the drum. The drum is made of iron wire rope drum, which can increase the number of wire rope winding circles, which is enough to meet various construction scopes. The wire rope is wound on the drum, and the wire rope passes through the pulley and one end of the cable. To connect, pull the cable through the wire rope.

The above-mentioned torque motors are set to two, and the two torque motors increase the power and are used for dragging the cables.

The above-mentioned steel wire rope is a double-twisted multi-strand round steel wire rope, and the double-twisted multi-strand round steel wire rope can prevent a large rebound when the steel wire rope suddenly breaks, preventing damage to construction personnel and protecting the safety of construction personnel.

The above-mentioned pulleys include horizontally arranged pulleys and longitudinally arranged pulleys, and there are two horizontally arranged pulleys, and the longitudinally arranged pulleys are arranged in the middle of the two horizontally arranged pulleys. The above-mentioned laterally arranged pulleys are set to be concave in the middle, and their diameters gradually increase from the middle to both sides, and the above-mentioned vertically arranged pulleys are set to be in the shape of an inverted cone. Utilize the pulley, can protect the cable from being worn when dragging on the ground or in some corners.

The beneficial effect of this utility model is:

(1) Instead of manually dragging and hanging cables, it greatly reduces the labor intensity of construction workers, shortens cable laying time, improves construction efficiency, and ensures the safety of construction workers;

(2) The cable is retracted in time, avoiding extrusion and collision, and prolonging the service life of the cable;

(3) Solve the problem of cable laying in various harsh environments;

(4) Increase the drag power, extend the wire rope, and expand the drag range of the cable;

(5) Simple operation and convenient use.

Detailed ways

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

As shown in Fig. 1 and Fig. 2, the cable pulling device described in the utility model includes a generator (1) and a motor, and the generator (1) can supply power for the motor at any time in the workplace, and the motor uses a torque motor (2) , because the torque motor (2) is used, when the drag torque is greater than its rated value, the torque motor (2) will automatically stop, which can avoid forced dragging due to the cable being stuck in the middle of the dragging process , so that the cable is dragged and damaged. The torque motor (2) is connected to the torque motor controller (3), and the torque motor controller (3) is used. There are ten gears for output adjustment, and stepless speed regulation can be achieved. The dragging speed can be very slow or very fast. The speed can be adjusted freely, so that the range and precision can be controlled. The torque motor controller (3) only has a knob and a switch button, which is simple and easy to control and convenient to use. The torque motor (2) is connected with the rotating bucket (5) by a chain (4). The rotating bucket (5) adopts an iron wire rope rotating bucket (5), which can increase the number of turns of the wire rope (6), so that the The wound steel wire rope (6) reaches hundreds of meters, which is enough to meet various construction scopes. When the cable is wound, the diameter of the drum (5) gradually increases. It is very important to keep the tension of the cable constant during the whole process, because too much tension can cause damage to the cable, while too little tension can cause winding slack. Therefore, the torque motor (2) is connected to the rotary barrel (5), so that when the diameter of the cable wound on the rotary barrel (5) increases, the output torque of the motor driving the rotary barrel (5) also increases, so that The tension of the cable remains unchanged, so that the winding speed of the cable remains unchanged. The steel wire rope (6) is wound on the drum (5), and the steel wire rope (6) is connected to the cable through the pulley block (7). Using the pulley block (7), the The friction between the cable and the ground improves work efficiency. As a new embodiment, there are two torque motors (2), which can enhance the power and be used for dragging the cables. The steel wire rope (6) is a double-twisted multi-strand round steel wire rope. The double-twisted multi-strand round steel wire rope can prevent a large rebound when the steel wire rope (6) suddenly breaks, preventing damage to construction personnel and protecting the construction site. personnel safety.

As shown in Figure 2, the pulley block (7) includes a horizontal pulley (7a) and a vertical pulley (7b). The horizontal pulley (7a) is connected to the tripod (8) through a shaft (9). The tripod (8) Fixed on the bracket base (10), the vertical pulley (7b) is connected to the tripod (8) through the shaft (9), the tripod (8) is fixed on the bracket base (10), and the horizontally set There are two pulleys (7a), and the longitudinally arranged pulley (7b) is arranged in the middle of the two transversely arranged pulleys (7a). The horizontal pulley (7a) is set to be concave in the middle, and its diameter gradually increases from the middle to both sides, which can prevent the cable from slipping to both sides during the dragging process, and the vertical pulley (7b) is set to be inverted conical , so that even at the corner position, the cable can be protected from wear and tear. When using it, a pulley block (7) can be added, which can reduce manpower and protect the cable. Pull for easy access.

The embodiment of the utility model has been described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiment, and for those of ordinary skill in the art, some modifications and improvements can be made without departing from the premise of the utility model , these should also be regarded as belonging to the protection scope of the present utility model.
