Description

Technical Field

[0001] The invention relates to the field of cable laying, and in particular to a device for cable laying. Background Art

[0002] Drag chain cable, also known as tank chain cable or dragging cable, is a highly flexible cable designed for use in drag chains. Drag chains are devices used to protect and manage cables, wires, air tubes and other linear components. They are often used in environments that require frequent linear or curved movements, such as automated production lines, robot arms, CNC machine tools, logistics systems, etc., and drag chain cables usually need to be laid on drag chain tracks for use.

[0003] At present, the drag chain cable is usually laid on the drag chain track manually. The specific operation is as follows: First, the operator needs to place the drag chain cable that has been neatly rolled up in advance at the starting point of the drag chain track. Then, the drag chain cable is manually unfolded and gradually pushed along the track until the cable is completely laid on the track to achieve the correct installation and positioning of the cable. However, this traditional method has significant defects. Due to the large weight of the drag chain cable itself, manual unfolding and pushing is not only time-consuming and labor-intensive, but also increases the physical burden of the operator, especially under long-term operation, which is easy to cause physical fatigue and affect work efficiency. What is more serious is that during the operation, the operator's hands are easily scratched by the edge of the cable or the gap between the tracks, which poses a high safety risk.

[0036] When the device is needed to lay the drag chain cable, first push the device to the designated drag chain track, and start the lifting mechanism 1 to rise according to the height of the drag chain track, drive the sliding base 2 to move upward to a height matching the drag chain track, and then close the lifting mechanism 1, and then pull the block 125 upward to release the lock on the cover plate 6, and then rotate the cover plate 6 to disengage it from the winding shaft 5, and then put the rolled drag chain cable on the winding shaft 5, and insert the end of the drag chain cable close to the winding shaft 5 into the through hole 51, and turn the worm 155 with the hexagonal wrench, the worm 155 drives the worm wheel 154 to rotate, and the bidirectional screw 152 rotates accordingly to drive the clamping plates 153 on both sides to move toward each other to clamp the drag chain cable. After fixing, people put the cover plate 6 on the winding shaft again. The shaft 5 is on the upper part and rotates in the opposite direction, so that the cover plate 6 moves backward and resets, and then the clamping block 125 moves downward and resets to clamp the cover plate 6 again. At this time, the electric push rod 11 can be started to control the telescopic rod of the electric push rod 11 to move forward and extend, driving the slider 111 to move forward. The forward movement of the slider 111 drives the inner housing 10, the winding shaft 5 and the cylindrical gear 8 to move forward, and the telescopic rod is extended, so that the inner housing 10 moves to the top of the drag chain track and is aligned with it. At the same time, the forward movement of the inner housing 10 will also drive the cover plate 6 to move forward. The forward movement of the cover plate 6 drives the clamping block 125 and the connecting block 124 to move forward, and the connecting ring 122 is pulled forward by the guide rod 126. The connecting ring 122 moves forward and drives the support rod 127 clockwise through the pull rope 128. Rotate, the support rod 127 rotates clockwise through the two bevel gears 129 to drive the first gear 120 to rotate clockwise, the reset member 1201 is deformed, and the first gear 120 rotates clockwise to drive the gear ring 121 and the rotating plate 7 to rotate counterclockwise, and the rotating plate 7 rotates to drive the inner shell 10 to rotate counterclockwise through the telescopic rod, so that the cutout on the upper part of the inner shell 10 rotates to a downward state and is located directly above the drag chain track, and the drag chain cable sleeved on the winding shaft 5 will naturally fall onto the drag chain track through the cutout on the inner shell 10, and then the electric push rod 11 is closed, and the electric gear 9 is started again. The rotation of the electric gear 9 drives the cylindrical gear 8 to rotate, and the rotation of the cylindrical gear 8 will drive the winding shaft 5 to rotate, so that the drag chain cable sleeved on the winding shaft 5 can be slowly The drag chain cable is evenly laid on the drag chain track to achieve the purpose of automatic laying. When the drag chain cable is about to be laid, the electric gear 9 is turned off, and the worm 155 is rotated in the opposite direction by a hexagonal wrench. The worm 155 drives the worm wheel 154 to rotate, and the bidirectional screw 152 rotates accordingly to drive the clamping plates 153 on both sides to move away from the drag chain cable in opposite directions. After the drag chain cable is loosened, it automatically slides onto the drag chain track to complete the laying operation of the chain cable. Then the electric push rod 11 is started to control its telescopic rod to move backward and shorten, driving the cover plate 6, the inner shell 10 and the winding shaft 5 to move backward and reset. At the same time, under the rebound action of the reset member 1201, it can drive the first gear 120, the bevel gear 129 and the support rod 127 to rotate and reset, so that the pull rope 128 is rewound around the support rod 127.The connecting ring 122 moves backward to reset, the guide rod 126, the connecting block 124 and the clamping block 125 move backward to reset, and finally the electric push rod 11 is closed.

The limiting wheel 135 can limit the drag chain cable to prevent the drag chain cable from arching upward during laying.

[0038] When the gear ring 121 rotates counterclockwise, it will drive the second gear 133 to rotate clockwise, and the clockwise rotation of the second gear 133 will drive the first screw 132 to rotate clockwise. The clockwise rotation of the first screw 132 will drive the propulsion rod 134 and the limiting wheel 135 to move forward, so that the limiting wheel 135 moves to the top of the drag chain track. When the cable laying device moves to the right, the drag chain cable is laid on the drag chain track, and the drag chain cable is located between the drag chain track and the limiting wheel 135. The drag chain cable is limited by the limiting wheel 135 to prevent the drag chain cable from arching upward during laying.

The second screw rod 142 is threadedly connected to the sliding base 2. The rotation of the second screw 142 can drive the sliding base 2 to move forward to adjust the distance between the drag chain track and the device. A rotating disk 143 is welded on the rear end of the second screw 142, and a handle is welded on the rear side of the rotating disk 143.

[0040] When the distance between the drag chain track and the device is large, people rotate the rotating disk 143, and the rotation of the rotating disk 143 drives the second screw 142 to rotate. The rotation of the second screw 142 can drive the sliding base 2 to move forward, and the guide rod 141 plays a guiding role, so that the distance between the drag chain track and the device can be adjusted. The design of this mechanism allows the distance to be quickly adjusted under special circumstances, enhances the adaptability of the laying device to different usage environments, and improves its practicality in a variety of application scenarios.
