Problems solved by technology

Due to the large number of electrical equipment in the cable shaft, when the two cables are conveyed underground at the same time, they will encounter different resistances. When the resistance of one cable increases, the tension of the cable will increase, resulting in damage to the cable insulation layer and threatening the safety of electricity use.

Embodiment 1

[0035] Such as figure 1 , image 3 with Figure 4 As shown, a cable tractor suitable for uneven areas of the present invention includes two clamping members 2, a first transmission mechanism 3, a second transmission mechanism 4, and a motor 5; the two clamping members 2 are arranged in parallel , And two clamping members 2 respectively clamp a cable 1; the motor 5, the second transmission mechanism 4 and the first transmission mechanism 3 are connected in sequence, and the second transmission mechanism 4 and the first transmission mechanism 3 connect the motor 5 The power is transmitted to the two clamping members 2, the two clamping members 2 drive the movement of the cable; the second transmission mechanism 4 includes a liquid tank 41, a turbine 42, a through hole 43, an input shaft 44, and a runner 45 And the output shaft 46; the liquid tank 41 is provided with liquid; the turbine 42 and the runner 45 are arranged oppositely in the liquid tank 41, and one end of the input sh...

Embodiment 2

[0038] Such as figure 2 As shown, this embodiment is based on Embodiment 1, and the liquid provided in the liquid tank 41 is engine oil. The clamping member 2 includes a driving wheel 21, a first crawler 22, a first driven wheel 23, a second driven wheel 24, a second crawler 25, and a third driven wheel 26; the first crawler 22 is arranged on the driving wheel 21 And the outer edge of the first driven wheel 23; the second track 25 is provided on the second driven wheel 24 and the third driven wheel 26; the driving wheel 21 is connected to the first transmission mechanism 3 and receives power.

[0039] In the implementation of this embodiment, since the compression ratio of the oil is very low, the oil is arranged in the liquid tank 41 to avoid waste of power output. By providing the above device, the cable 1 can be tightly clamped by the clamping member 2.

Embodiment 3

[0041] In this embodiment, on the basis of Embodiment 1, the diameter of the through hole 43 provided on the turbine 42 is 10-15% of the diameter of the turbine 42. The height of the blades of the runner 45 is 15-20% of the diameter of the runner 45. The blades of the turbine 42 use 10-15% of the diameter of the turbine 42.

[0042] During the implementation of this embodiment, the inventor found that when the diameter of the through hole 43 is 10-15% of the diameter of the turbine 42, it can effectively prevent the power output of the runner 45 from being too large, and it can also avoid the rotation of the runner 45 from being too low. . The height of the blades of the runner 45 is 15-20% of the diameter of the runner 45, so that the runner 45 is more sensitive to the flow of liquid, and the sensitivity of the entire device is improved. The blades of the turbine 42 use 10-15% of the diameter of the turbine 42, so that when the turbine 42 drives the liquid to rotate, the energ...

Abstract

The invention discloses a cable retractor applicable for uneven areas. A cable is clamped by two clamping pieces respectively; a first transmission mechanism and a second transmission mechanism are used for conveying power of a motor to the two clamping pieces, and the two clamping pieces drive the cable to move; a turbine and a runner are arranged inside a liquid box oppositely, one end of an input shaft is connected to the turbine, the other end of the input shaft is connected to the output end of the motor; one end of an output shaft is connected to the runner, and the other end of the output shaft is connected to the first transmission mechanism; a through hole running through the turbine is formed in the turbine; the axle of a first helical gear is connected to the clamping pieces and is used for outputting the power, a fifth helical gear is engaged with a side gear, and the axle of the fifth helical gear is connected to the output shaft and is used for receiving the power. According to the cable retractor applicable for the uneven areas disclosed by the invention, through interaction of the first transmission mechanism and the second transmission mechanism, continuous two-stage speed reduction for the cable receiving resistance through mechanical mechanisms is realized, so that the tension on the cable is reduced, the safety of electricity utilization is improved, and the reliability is high.

Description

Technical field [0001] The present invention relates to the field of electric power engineering, in particular to a cable tractor suitable for uneven areas. Background technique [0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station outgoing lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across the river. In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels, various insulated power cables. The use of power cables has a history of more than 100 years. In 1879, American inventor T.A. Edison wrapped jute on a copper rod and threaded it into an iron pipe, and then filled it with asphalt mixture to make a cable. He laid this cable in New...
