Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] Such as figure 1 , figure 2 As mentioned above, a cable retracting device includes a wire storage box 100 , a traction wheel 200 and a cable 400 . A number of pulleys A110 arranged in a straight line are fixedly arranged in the wire storage box 100, a slide plate 130 is slidably arranged in the wire storage box 100, and a number of pulleys B120 arranged in a straight line are fixedly arranged on one side of the slide plate 130. The A110 is opposite to the pulley B120, and the skateboard 130 can drive the pulley B120 to move closer to or away from the pulley A110. The traction wheel 200 is arranged on one side of the wire storage box 100 , the side of the wire storage box 100 close to the traction wheel 200 is provided with a threa...

Abstract

The invention discloses a cable take-up and pay-off device, and relates to the technical field of equipment power supply. The device comprises a storage box, a traction wheel and a cable, wherein a plurality of pulleys A are fixedly arranged in the storage box, a sliding plate is slidably arranged in the storage box, a plurality of pulleys B are fixedly arranged on the sliding plate, the pulleys A and the pulleys B are oppositely arranged, and the sliding plate can drive the pulleys B to move close to or away from the pulleys A; the traction wheel is arranged on one side of the storage box, and a threading hole A and a threading hole B are formed in the storage box; and the cable is wound on the traction wheel by one circle, one end of the cable penetrates through the threading hole A, bypasses the pulleys A and the pulleys B alternately and then penetrates out of the threading hole B, and the cable can freely slide in the threading hole A and is fixedly connected with the storage box at the threading hole B. The device can directly supply power by adopting the whole cable with good insulativity, so that the power supply safety is ensured; and during take-up and pay-off, the position of the end, connected with an external power source, of the cable can keep unchanged, so that the problems of cable disorder and mutual winding are avoided.

Description

technical field [0001] The invention relates to the technical field of equipment power supply, in particular to a retractable cable device. Background technique [0002] Affected by complex terrain conditions and harsh natural environment, it is inevitable to build a large number of tunnels when building high-altitude railways and highways. Influenced by special construction conditions such as complex geological conditions and fragile ecological environment, its construction is extremely difficult. At present, the drilling and blasting method is usually used to excavate tunnels. However, in high-altitude environments, internal combustion engine equipment is likely to suffer from insufficient fuel combustion, resulting in a sharp drop in equipment power, increased fuel consumption, and a large increase in toxic and harmful substances in the exhaust gas emitted by the equipment. The rise has greatly affected the efficiency, quality and safety of the overall construction of th...
