Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a cable traction device used in power construction. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals. It typically consists of an outer insulating protective shell and multiple sets of conductors inside. During cable laying operations, due to the significant weight of the cable, a traction device is required to pull the cable to the designated installation location, thereby facilitating subsequent cable installation.

[0003] Traditional cable traction devices use two drive tracks to pull and transport the cable. The two drive tracks first clamp the cable, and then pull and transport the cable by rotating relative to each other. This makes the cable's stress point relatively singular (only on the left and right sides), which can easily cause the cable to be squeezed and deformed, resulting in damage and affecting the cable's service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a cable traction device for power construction, which has more uniform force distribution and avoids damage to the cable during traction.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cable traction device for power construction, including a base, a traction box fixedly connected to the base, an inlet and an outlet at both ends of the traction box, a fixed frame arranged on both sides fixedly connected inside the traction box, a conductor tube arranged coaxially with the inlet and outlet fixedly connected between the two fixed frames, an adjustment hole arranged in a circular array on the conductor tube, a traction swing arm rotatably connected to each adjustment hole, a centering adjustment mechanism for driving the traction swing arm to swing synchronously inside the traction box, a U-shaped frame fixedly connected to one end of the traction swing arm, a conductor wheel rotatably connected inside the U-shaped frame, a motor for driving the conductor wheel to rotate fixedly connected to the U-shaped frame, a cavity inside the conductor wheel, and suction holes evenly arranged and communicating with the cavity on the outer wall of the conductor wheel, and a high-pressure suction mechanism that cooperates with the cavity on the U-shaped frame.

[0006] As an improvement, the centering adjustment mechanism includes an adjustment ring that is slidably sleeved on the outer wall of the guide tube, a gear that is rotatably connected inside the adjustment hole, a traction swing arm that is fixedly connected to one side of the gear, a rack that meshes with the gear that is fixedly connected to one side of the adjustment ring, and a hydraulic cylinder that drives the adjustment ring to slide that is fixedly connected to one side of the fixed frame.

[0007] As an improvement, the high-pressure suction mechanism includes a high-pressure suction pump fixedly connected to one side of the U-shaped frame. The input end of the high-pressure suction pump is fixedly connected to a suction pipe arranged coaxially with the guide wheel. A connection socket that mates with the suction pipe is provided on one side of the guide wheel. The suction pipe is rotatably connected to the connection socket.

[0008] As an improvement, the traction box is fixedly connected with multiple movable sleeves arranged around the inlet. Each movable sleeve has a centering clamp block slidably inserted into it at the end near the inlet. A centering spring that cooperates with the centering clamp block is fixedly connected inside the movable sleeve.

[0009] As an improvement, one end of the centering clamp is rotatably connected to the centering pulley.

[0010] As an improvement, a rubber suction nozzle is fixedly connected to one end of the air intake hole.

[0011] As an improvement, a limiting slide rod is fixedly connected between the two fixed frames, and the adjusting ring is provided with a sliding hole that cooperates with the limiting slide rod.

[0012] The advantages of this utility model compared with the prior art are as follows: After inserting one end of the cable to be pulled into the through-conductor cylinder through the inlet, it extends out from the outlet. The centering adjustment mechanism is activated to drive the traction swing arm to swing synchronously toward the cable, pushing the cable to a position coaxial with the through-conductor cylinder. At the same time, multiple guide wheels simultaneously press against the outer wall of the cable, making the cable more evenly stressed and avoiding damage to the cable during the traction process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, a cable pulling device for power construction includes a base, on which a pulling box 1 is fixedly connected. The pulling box 1 has an inlet 19 and an outlet 20 at its two ends. Fixed frames 2 are fixedly connected inside the pulling box 1, arranged on both sides. A conductor tube 3, coaxially arranged with the inlet 19 and outlet 20, is fixedly connected between the two fixed frames 2. The conductor tube 3 has adjusting holes 4 arranged in a circular array. A pulling arm 5 is rotatably connected to each adjusting hole 4. The pulling box 1 contains a mechanism for synchronously driving the pulling arms 5. The centering adjustment mechanism includes an adjustment ring 13 that is slidably sleeved on the outer wall of the guide tube 3. A limiting slide rod 12 is fixedly connected between the two fixed frames 2. The adjustment ring 13 is provided with a sliding hole that cooperates with the limiting slide rod 12. A gear 6 is rotatably connected in the adjustment hole 4. The traction swing arm 5 is fixedly connected to one side of the gear 6. A rack 14 that meshes with the gear 6 is fixedly connected to one side of the adjustment ring 13. A hydraulic cylinder 15 that drives the adjustment ring 13 to slide is fixedly connected to one side of the fixed frame 2.

[0020] One end of the traction swing arm 5 is fixedly connected to a U-shaped frame 21. A guide wheel 7 is rotatably connected inside the U-shaped frame 21. A motor 8 that drives the guide wheel 7 to rotate is fixedly connected to the U-shaped frame 21. The guide wheel 7 has a cavity inside. The outer wall of the guide wheel 7 has evenly arranged air intake holes communicating with the cavity. A rubber air intake nozzle 9 is fixedly connected to one end of the air intake hole. The U-shaped frame 21 is provided with a high-pressure air extraction mechanism that cooperates with the cavity. The high-pressure air extraction mechanism includes a high-pressure air pump 10 fixedly connected to one side of the U-shaped frame. The input end of the high-pressure air pump 10 is fixedly connected to an air extraction pipe 11 arranged coaxially with the guide wheel 7. One side of the guide wheel 7 is provided with a connection insertion hole that cooperates with the air extraction pipe 11. The air extraction pipe 11 is rotatably connected to the connection insertion hole.

[0021] The traction box 1 is fixedly connected to a plurality of movable sleeves arranged around the inlet 19. Each movable sleeve has a centering clamp 16 slidably inserted into one end near the inlet 19. A centering spring 17 that cooperates with the centering clamp 16 is fixedly connected inside the movable sleeve. One end of the centering clamp 16 is rotatably connected to a centering pulley 18.

[0022] In practical use, one end of the cable is inserted into the inlet 19. The centering pulley 18 is pressed, causing the centering clamp 16 to slide synchronously into the movable housing. This compresses the centering spring 17, causing it to deform. Through the centering clamp 16 and the centering pulley 18, the cable enters more stably. After passing through the conductor tube 3, the cable extends from the outlet 20. The hydraulic cylinder 15 is activated, driving the adjusting ring 13 to slide the limiting slide rod 12. The adjusting ring 13 drives the rack 14 to slide, which in turn drives the gear 6 to rotate synchronously. The gear 6 then drives the traction swing arm 5 to swing synchronously, causing the conductor... Wheel 7 rests against the outer wall of the cable. The motor 8 is started to drive the guide wheel 7 to rotate. The guide wheel 7 drives the cable to be pulled and transported, so that the cable continuously extends out from the outlet 20. The high-pressure air pump 10 is started to continuously pump air from the cavity inside the guide wheel 7, so that the airflow continuously enters through the rubber air nozzle 9. When the rubber air nozzle 9 contacts the outer wall of the cable, it further adsorbs the cable, improves the adhesion between the guide wheel 7 and the outer wall of the cable, and the rubber air nozzle 9 also further improves the friction between the outer wall of the cable and the guide wheel 7, preventing the outer wall of the cable from slipping.
