A cable pay-off device that changes resistance based on coil mass

Abstract

The invention discloses a cable paying-off device capable of changing the resistance based on coil mass. The structure of the cable paying-off device capable of changing the resistance based on the coil mass comprises a cable paying-off reel, a resistance adjusting device, a moving wheel and a paying-off reel supporting frame. The cable paying-off device is provided with the resistance adjusting device, when the cable paying-off device is in use, along with reduction of the cable on the paying-off reel, mass detecting devices push paying-off reel linkage structures to move upwards, resistanceof rotation, on a linkage shaft fixing frame, of the paying-off reel linkage structures is increased at the same time, under the action of magnetic induction structures, the rotation resistance is slowly increased through attraction; and in this way, the situation that after the quantity of the cable on the cable paying-off reel is reduced, the friction force is reduced, under the action of inertia, the cable is thrown away, fall onto the ground and makes friction with the ground, so that the cable is worn or a cable core is exposed is effectively avoided, the service life of the cable is prolonged, and the safety of cable installation is improved.

Description

technical field [0001] The invention relates to the field of a cable conveying device, in particular to a cable pay-off device that changes resistance based on the mass of a coil. Background technique [0002] The main work of the power system is to erect or lay various power supply lines and ensure the normal power supply of each power supply line. With the rapid development of the national power grid, during the existing cable construction process, when the cable is laid into the pipeline, the cable will be removed from the pay-off device. It is pulled up and laid in the installation groove one by one, but the current technical considerations are not perfect, and it has the following disadvantages: when the existing pay-off device draws out the cable, at the beginning, there are many cable rolls and the quality is large, so the cable is pulled when pulling. The friction of the pay-off reel is relatively large, so the speed of cable extraction is slow. When the cable on the...

[0002] The main work of the power system is to erect or lay various power supply lines and ensure the normal power supply of each power supply line. With the rapid development of the national power grid, during the existing cable construction process, when the cable is laid into the pipeline, the cable will be removed from the pay-off device. It is pulled up and laid in the installation groove one by one, but the current technical considerations are not perfect, and it has the following disadvantages: when the existing pay-off device draws out the cable, at the beginning, there are many cable rolls and the quality is large, so the cable is pulled when pulling. The friction of the pay-off reel is relatively large, so the speed of cable extraction is slow. When the cable on the pay-off reel is drawn less and less, the cable volume becomes less, and the quality also decreases. The friction force decreases and the extraction speed becomes smaller. At the same time, under the action of inertia, the pay-off reel will continue to rotate after the extraction stops, causing the cable to be thrown out and fall to the ground. During the process of pulling and laying the cable, the surface of the cable will rub against the rough ground, causing the insulation protection layer to be worn. , shorten the service life of the cable, and in severe cases, the insulation layer will be worn out and the wire core will be exposed, which will pose a greater safety hazard after power-on
