Description

Downhole cable laying device

technical field

The utility model relates to an underground cable laying device, which belongs to the field of electric equipment.

Background technique

In the prior art, when laying cables downhole, the cables are usually placed manually down the well. This operation causes the cables to fail to fall accurately to the bottom of the well, which is not conducive to saving the length of the cables, and the cables are directly put into the well for long-term use. , susceptible to erosion by rain and foreign objects. Concrete is used to seal around the wellhead, and the height is generally relatively low, which can easily lead to water ingress in the cable well. In addition, the speed of the guide wheel needs to be controlled. If the control is not good, the wire rope is placed too slowly, which will affect the work efficiency. affect the progress of work.

Utility model content

According to the deficiencies in the prior art above, the technical problem to be solved by the utility model is: to provide an underground cable laying device which saves the cable length, increases the service life of the cable and is easy to operate.

The technical scheme that the utility model solves its technical problem adopts is:

The downhole cable laying device includes a cable rack, a support base is set at the bottom of the cable rack, a wellhead bracket is set on one side of the cable rack, a guide wheel is arranged on the wellhead bracket, a steel wire rope is wound on the guide wheel, the guide wheel is connected with the governor, and the steel wire rope is connected with the governor. The cables are connected together by clamps under the guide wheels. A cable well is installed on the ground below the wellhead support. Steel pipes are added inside the cable wells. The steel pipes are 1.1-1.5m above the ground. The surroundings of the steel pipes are sealed with concrete and the upper part of the steel pipes is covered.

The steel pipe is preferably 1.2m higher than the ground, coupled with the concrete seal, rainwater and foreign objects will not enter the cable shaft, which increases the service life of the cable.

When working, first determine the depth of the cable well, so as to determine the length of the wire rope, then wind the wire rope on the guide wheel for laying, fix the cable with the wire rope with a clamp, adjust the governor, and slowly lower the cable, while Put the cable on one side and install the fixture until the cable is put into the bottom of the well.

The beneficial effects that the utility model has are:

The guide wheel of the utility model is equipped with a governor, and the speed is controlled evenly, which is convenient for operation; the utility model has a simple structure, saves the length of the cable, prevents rainwater and foreign objects from entering the cable well, and increases the service life of the cable.

Detailed ways

Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

As shown in Figure 1, the underground cable laying device includes a cable rack 1, a support base 2 is arranged at the bottom of the cable rack 1, a wellhead bracket 8 is arranged on one side of the cable rack 1, and a guide wheel 10 is arranged on the wellhead bracket 8, and the guide wheel 10 The steel wire rope 12 is wound on the top, the guide wheel 10 is connected with the governor 9, the steel wire rope 12 and the cable 11 are connected together by the fixture 4 under the guide wheel 10, and the cable well 3 is set on the ground at the lower part of the wellhead support 8, and the inside of the cable well 3 is added. The steel pipe 5 is 1.1-1.5m higher than the ground, the surroundings of the steel pipe 5 are sealed with concrete 6 , and the upper part of the steel pipe 5 is provided with a manhole cover 7 .

The steel pipe 5 is preferably 1.2m higher than the ground, and with the sealing of the concrete 6, rainwater and foreign objects will not enter the cable shaft 3, which increases the service life of the cable 11.

When working, first determine the depth of the cable well 3, thereby determining the length of the steel wire rope 12, then wind the steel wire rope 12 on the guide wheel 10 for laying, fix the cable 11 with the clamp 4 and the steel wire rope 12, and adjust the governor 9. Lower the cable 11 slowly, and install the fixture 4 while putting the cable 11 down until the cable 11 is put into the bottom of the well.
