Description

A cable pulley for passing through pipes

technical field

The invention relates to a tool in the field of electric power, in particular to a pulley for passing cables through pipes.

Background technique

The laying method of 10kV power cables is basically pipe laying, and the material of the cable pipes is hard PVC and PE pipes.

In the current construction of power cable laying, the laying of cables in the well is completely dependent on manpower. The laying of 10kV power cables mainly has problems such as low construction quality, more labor, and long time consumption. major factor in progress. In addition, when the cable enters the pipe, the cable is in direct contact with the cable pipe, and the cable is prone to wear around the pipe opening, which will damage the surface of the cable and affect the construction quality.

Contents of the invention

The technical task of the present invention is to provide a cable pulley for threading pipes in order to address the above-mentioned technical deficiencies.

The technical solution adopted by the present invention to solve the technical problem is a pulley for cable passage, including a pulley, a pulley bracket and a lifting operating rod, the pulley is mounted on the pulley bracket through bolts and bearings; the pulley bracket is provided with a cable slideway and an arc-shaped splint, the arc-shaped clamp is located below the cable slideway, and the center point of the inner diameter of the cable slideway is on the same straight line as the center point of the upper slope surface of the pulley; the lifting rod includes an upper rod, a lower rod and The latch, the upper rod and the lower rod are mutually socketed, and are provided with a plurality of sockets, the top of the upper rod is provided with fastening bolts, and is connected with the pulley bracket through the fastening bolts, and the lower end of the lower rod is provided with With base.

Preferably, the cable slideway is in a semi-cylindrical shape, and the center of the cross section of the cable slideway coincides with the center of circle of the same cross section of the arc splint.

The beneficial effects brought by the invention are: it can avoid the jamming of the cable in the cable duct, improve the work efficiency, reduce the abrasion of the cable at the mouth of the tube, and prolong the service life of the cable.

detailed description

Below in conjunction with accompanying drawing, the present invention is described in detail below.

As shown in Fig. 1 and Fig. 2, the present invention discloses a cable pulley for threading pipes, including a pulley 1, a pulley bracket 2 and a lifting operation rod, and the pulley 1 is installed on the pulley bracket 2 through bolts 5 and bearings.

The pulley bracket 2 is provided with a cable slideway 3 and an arc splint 4, the arc clamp is located below the cable slideway 3, and the cable slideway 3 is in a semi-cylindrical shape, the cross section of the cable slideway 3 The center of circle coincides with the center of circle of the same cross section of the arc splint 4; the center point of the inner diameter of the cable slideway 3 is on the same straight line as the center point of the upper end slope of the pulley 1.

The lifting rod includes an upper rod 8, a lower rod 9 and a latch, the upper rod 8 and the lower rod 9 are mutually socketed, and each is provided with a plurality of sockets, the top of the upper rod 8 is provided with a fastening bolt 5, And it is connected with the pulley bracket 2 through fastening bolts 5 , and the lower end of the lower rod 9 is provided with a base 10 .

In the process of using the present invention, the user first adjusts the height of the lifting rod to a suitable position, and fixes the upper rod 8 and the lower rod 9 through the latch and the socket. Then, the user fixes the pulley 1 on the pulley 1 fixing frame through the fastening bolt 5, thus completing the assembly of the whole device.

When threading cables, the user first embeds the pipe wall at the nozzle of the cable conduit between the cable slideway 3 and the arc splint 4, so that the nozzle of the cable conduit faces the pulley 1 and fixes it on the pulley bracket 2. When the user pushes the cable to the cable duct, with the assistance of the pulley 1 and the cable slideway 3, the cable can enter the cable duct steadily, which not only avoids the jamming of the cable in the cable duct, improves the work efficiency, but also reduces the The wear of the cable at the nozzle prolongs the service life of the cable.

To sum up, the present invention can avoid the jamming of the cable in the cable duct, improve the work efficiency, reduce the abrasion of the cable at the mouth of the duct, and prolong the service life of the cable, which is worthy of popularization.

The above descriptions are only preferred implementations of the present invention, and the scope of protection of the present invention is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present invention belong to the scope of protection of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
