Description

Technical Field

[0001] The present invention relates to the technical field of cable laying equipment, and particularly to an auxiliary conveying device for laying electric wires and cables. Background Technique

[0002] With the continuous development of China's electric power infrastructure construction, there are more and more long-distance cable lines. During the laying process of cable lines, cable conveyors are required for laying. The cable conveyor is an automated processing device for long-distance cable laying. Along the cable laying path, a cable tractor needs to be arranged at intervals. At the cable laying terminal, the cable conveyor is used in cooperation with the cable tractor to achieve long-distance cable laying.

[0003] However, before connecting the cable to the cable conveyor, since there is a long distance between the cable reel and the cable conveyor, generally, one end of a rope that is easy to retract and extend is used to connect to the cable, and the cable conveyor is used to pull the other end of the rope until the cable end is pulled out to the position of the cable conveyor. Then, the equipment is stopped. Subsequently, the equipment is adjusted to remove the rope, and then the cable end is connected to the cable conveyor. After starting the machine again, the cable can be conveyed. The whole operation process is relatively cumbersome. The invention patent with the publication number of CN117383347A discloses a conveying device for laying power cables, which improves the conveying efficiency by automatically cutting the rope. This method causes greater damage to the rope. At the same time, directly bundling the cable with one end of the rope has a low operation efficiency, and it is easy to fall off during the pulling process. Summary of the Invention

One end of the swing rod 6 is conical. The connecting mechanism 4 can drive the swing rod 6 to insert and connect to the surface of the cable 40 by inserting one end of the cable 40 into the sleeve 5 during the process of pulling the pulling rope 2, improving the fixing efficiency. The pulling mechanism 7 is installed on the base 1 and is used to drive the pulling rope 2 to wind. When the sleeve 5 reaches the set position, the connection state between the swing rod 6 and the cable 40 is automatically released. The conveying unit 8 is installed on the base 1 and is used to control the two side conveyors 3 to maintain a set distance during the pulling stage, so that the sleeve 5 can pass through between the two side conveyors 3. When the connecting mechanism 4 releases the connection state with the cable 40, it controls the two side conveyors 3 to automatically close to complete the clamping and conveying of both sides of the cable 40.

[0031] The control member 13 includes a control rod 14 slidably connected to the inner wall of the device slot 10. Both sides of the end of the control rod 14 close to the stopper 11 are chamfered. An inclined surface 15 slidably fitted with one end of the control rod 14 is formed on the stopper 11. A tension spring 16 fixedly connected to the device slot 10 is fixedly connected to the end of the control rod 14 away from the stopper 11.

The sliding ring 18 is slidably connected to the inner wall of the storage cavity 19. A second spring 20 fixedly connected to the storage cavity 19 is fixedly connected to the sliding ring 18. A plurality of communication pipes 21 for communicating the storage cavity 19 with the device slot 10 are formed in the sleeve 5. Hydraulic oil is stored in the storage cavity 19.

[0033] The pulling mechanism 7 includes a first bracket 22 fixedly installed on the base 1. A winding shaft 23 is rotatably connected to the first bracket 22. A driving motor 24 is fixedly connected to the first bracket 22. The model of the driving motor 24 is preferably YYHS-40. The output end of the driving motor 24 is fixedly connected to one end of the winding shaft 23. One end of the pulling rope 2 is fixedly connected to the outer wall of the winding shaft 23. A guiding member 25 for guiding the pulling rope 2 and the cable 40 is provided on the base 1. The guiding member 25 includes a second bracket 38 fixedly installed on the base 1. Two guiding wheels 39 are respectively provided on the first bracket 22 and the second bracket 38. A releasing member 26 for pushing the position of the sliding ring 18 is provided on the first bracket 22.

[0034] The releasing member 26 includes a lifting frame 27 slidably connected to the side surface of the first bracket 22 in the vertical direction. A fixed cylinder 28 is fixedly connected to the lifting frame 27. The pulling rope 2 passes through the fixed cylinder 28 and is movably sleeved with the inner wall of the fixed cylinder 28. A limiting block 29 is slidably connected to the base 1 in the horizontal direction. The width of the limiting block 29 is the same as the diameter of the sleeve 5. A third spring 30 fixedly connected to the base 1 is fixedly connected to the limiting block 29. A connecting rope 31 fixedly connected to the limiting block 29 is fixedly connected to the bottom of the lifting frame 27.

[0035] The conveying unit 8 includes a sliding frame 32 fixedly installed at the bottom of the conveyor 3. The sliding frame 32 is slidably connected to the inner wall of the base 1 in the horizontal direction. Two groups of electric telescopic rods 33 are fixedly connected to the base 1. The output end of the electric telescopic rod 33 is fixedly connected to a pushing plate 34 slidably connected to the inner wall of the base 1. A fourth spring 35 fixedly connected to the sliding frame 32 is fixedly connected to the pushing plate 34. A limiting plate 37 is fixedly connected to the sliding frame 32. Both sides of the limiting block 29 can be slidably attached to the outer walls of the two limiting plates 37 in the horizontal direction respectively.

[0036] Working principle: Pass the sleeve 5 through the position between the guide wheels 39, drive the pull rope 2 to the required position, so that the pull rope 2 on the winding shaft 23 is gradually loosened. Insert one end of the cable 40 into the sleeve 5. In the initial state, the clockwork rotating shaft 9 drives the swing rod 6 to rotate to one side of the inclined sliding ring 18, and the included angle between the swing rod 6 and the vertical direction is 45°. At this time, it is convenient to insert one end of the cable 40 to the innermost side of the sleeve 5. When inserting the cable 40, the outer wall of the cable 40 will push the swing rod 6 to swing around. After the insertion is completed, pull the cable 40 outwards. The outer wall of the cable 40 drives the swing rod 6 to swing in the reverse direction. At this time, the tip of the swing rod 6 will be inserted and fixed to the surface of the cable 40. Until the swing rod 6 rotates to the vertical state, at this time, the side of the swing rod 6 is blocked by the stopper 11 and cannot swing any further, then the fixation between the sleeve 5 and the cable 40 can be completed. The cable 40 cannot be directly pulled out of the sleeve 5 hereafter. This fixing operation is fast and stable.

[0037] Pre-adjust the distance between the two conveyors 3 according to the diameter of the cable 40 in advance. Start the electric telescopic rods 33 on both sides to push the pushing plate 34 to compress the fourth spring 35, so that the two sliding frames 32 move closer to the middle synchronously until the side of the limiting plate 37 abuts against the limiting block 29. After that, the sliding frame 32 cannot be closed any further, and the fourth spring 35 is compressed, thus ensuring that the distance between the two conveyors 3 is slightly larger than the diameter length of the sleeve 5, so that the pull rope 2 can freely drive the sleeve 5 and the cable 40 to pass through between the two conveyors 3. At the same time, the distance between the upper and lower guide wheels 39 also needs to be larger than the diameter of the sleeve 5. Start the drive motor 24 to drive the winding shaft 23 to wind up the pull rope 2. The pull rope 2 is bent and guided under the guidance of the fixed cylinder 28 and the guide wheels 39, driving the sleeve 5 and the cable 40 to be gradually conveyed to the position between the two conveyors 3. After the sleeve 5 passes through the guide wheels 39 and the conveyor 3, it turns at the position of the guide wheels 39 on the first bracket 22.

[0038] The pull rope 2 drives the sleeve 5 to move vertically upward until one side of the sliding ring 18 abuts against the bottom of the fixed cylinder 28. The bottom end area of the fixed cylinder 28 is small enough to just push the sliding ring 18 to slide in the storage cavity 19. While compressing the second spring 20, the hydraulic oil in the storage cavity 19 is delivered to the communicating pipe 21 and the device slot 10, pushing the control rod 14 to slide. The tip of the control rod 14 pushes the inclined surface 15 on the stop block 11, causing the stop blocks 11 on both sides to slide to both sides respectively, compressing the first spring 12. The side surface of the stop block 11 gradually releases the abutment against the swing rod 6. After that, the swing rod 6 can continue to swing towards the opening side of the sleeve 5, so as to release the plugging and fixing state of the tip of the swing rod 6 against the outer wall of the cable 40.

[0039] After the sliding ring 18 slides to the maximum displacement, the upward movement of the sleeve 5 will push the fixed cylinder 28 and the lifting frame 27 to move upward. The lifting frame 27 drives the connecting rope 31 to pull the limit block 29 to slide, compressing the third spring 30. The limit block 29 gradually withdraws from between the limit plates 37 on both sides. After that, under the push of the fourth springs 35 on both sides, the sliding frame 32 quickly moves closer to the middle, driving the conveyor 3 above to clamp both sides of the cable 40. At this time, the cable 40 is just between the two guide wheels 39 on the first bracket 22 and the two guide wheels 39 on the second bracket 38. The middle part is clamped and conveyed by the conveyor 3, and a stable guiding and conveying function can be realized. At this time, the middle part of the cable 40 is pushed to one side of the first bracket 22, driving one end of the cable 40 to gradually slide out downward from the sleeve 5. At this time, the swing rod 6 swings downward until the cable 40 completely disengages from the sleeve 5. The swing rod 6 is driven by the spring winding shaft 9 to reset to the initial inclined state again. After that, the cable 40 can be directly pulled and conveyed by the conveyor 3.

[0040] It should be noted that: the clamping distance between the two conveyors 3 is directly related to the pushing distance of the electric telescopic rod 33. The elastic force of the fourth spring 35 is large. During the conveying process of the cable 40, it can always push the conveyor 3 to maintain the clamping relationship with the outer wall of the cable 40, improving the conveying stability. The elastic force of the third spring 30 is large, which can prevent the limit block 29 from sliding significantly during the process of the pull rope 2 rubbing and pulling the inner wall of the fixed cylinder 28. Only after the sleeve 5 directly abuts against the fixed cylinder 28, can the continuous operation of the driving motor 24 drive the limit block 29 to slide significantly, releasing the limit blocking state of the two limit plates 37. The bottom of the fixed cylinder 28 can adopt a magnetic structure to magnetically fix the sleeve 5 and the sliding ring 18, preventing the sleeve 5 from moving downward from the fixed cylinder 28 after the driving motor 24 stops running.

[0041] After the conveying is completed, the cable 40 is taken out of the conveyor 3. The electric telescopic rods 33 on both sides are controlled to drive the pushing plates 34 to slide to both sides, so as to pull the sliding frame 32 and the conveyor 3 to move through the fourth spring 35. The conveyor 3 opens to both sides. At this time, under the push of the third spring 30, the limiting block 29 moves again between the limiting plates 37 on both sides, which is convenient for initially limiting the distance between the conveyors 3 during the closing process of the conveyor 3. The sleeve 5 is passed through between the guide wheels 39 and the conveyors 3 on both sides, and the cable 40 can be fixed and pulled for conveying operation again.

[0042] The operation of this device is convenient, which is convenient for stably fixing the cable 40. At the same time, it can automatically release the connection state between the pulling rope 2 and the cable 40 after the cable 40 is conveyed to the position between the conveyors 3, and the switching of the cable 40 conveying can be completed without manual operation, greatly improving the operation efficiency of the cable 40 conveying.
