[0035] (1) The present application needs to adapt to the ups and downs of the terrain when laying in the field, at this time the cable will produce a height difference, the emergence of this height difference in the field changes the stress state of the cable, the cable needs to overcome its own gravity along the slope of the force in the upward direction, the greater this height difference, the greater this component, at this time the motor in the device may be overheated because of too large load, resulting in motor trip even burnout, at the same time it will also cause the wear and tear of the transmission belt and damage the cable sheath, by rotating the rotating rod, the torsional spring in the rotating rod and the slider will accumulate potential energy at this time, the rotating turntable drives the connecting rod to pull the clamping block away from the inside of the clamping groove, so that the staff adjusts the roller, the roller takes the convex block and the slider up and down, when adjusted to the appropriate position, the staff releases the rotating rod, the torsional spring in the rotating rod and the slider will release the elastic potential energy when the staff releases his hand, so that the rotating rod rotates again, the rotating rod will make the turntable start to rotate, at this time the rotation of the turntable is over, the connecting rod will return to the horizontal state, the clamping block will enter the inside of the clamping groove again to lock, through this way, the position of the front and rear rollers can be adjusted up and down, which can actively create a smooth vertical bending path for the cable, so that its path is lifted and guided, which reduces the resistance during laying and reduces the energy consumption of the equipment.

[0036] (2) When the cable is close to the push rod, it will make the push rod produce transverse displacement, the convex block at the bottom of the transverse displacement push rod will make the rotating bar rotate, the rotating bar will push the sliding rod, the sliding rod will move upward along the slot on the convex block, so that the positioning rod is inclined, which will actively guide the cable to be inclined upward when it needs to make a horizontal turn, forming a natural vertical curve, providing a supporting force for the cable in the bending state, preventing the bending of the cable from being aggravated during transportation, causing great damage to the cable body. After the laying is completed, there is no cable on the roller, at this time the push rod will not be subjected to pressure again, so that the push rod is reset by the potential energy accumulated in the spring inside the compressed positioning bar.

[0037] (3) The present application provides a rotating bar that is rotated by the pressure of the cable, which pushes the sliding rod, so that the positioning rod is inclined, and the positioning rod in the inclined state will make the roller fit the curved part of the cable, which will change the sliding friction of the cable in the curved state into rolling friction, which reduces the resistance during laying of the cable, and also prevents the cable in the curved state from scratching the two sides of the sliding column and the fixed column, causing damage to the protective layer on the outer wall of the cable.

[0038] (4) The staff first rotates the rotating rod, so that the turntable rotates, the rotating turntable will drive the connecting rod to stretch the clamping block, the stretched convex block will be separated from the inside of the clamping groove, so that the staff can adjust the position of the front and rear rollers up and down, which can speed up the adjustment speed of the staff, save the setting time, and fundamentally eliminate the problem of thread jamming caused by mud and rust, reduce the maintenance difficulty.

[0071] The outer wall of the protruding block 321 is provided with three notches, four baffles, and the same inclined notches are formed on the middle two baffles, and the sliding rod 323 slides in the inclined notches on the protruding block 321.

[0072] The thrust mechanism 4 comprises:

[0073] Pushing assembly 41, pushing assembly 41 is rotationally connected at the outer wall of the protrusion 321;

[0074] Telescopic assembly 42, telescopic assembly 42 is slidingly connected at the outer wall of the protrusion 321, after the laying is completed, there is no cable on the roller 324, at this time the push rod 411 will not be under pressure, then the potential energy accumulated by the spring inside the compression positioning strip 421 through the stretching block 422, the push rod 411 resets.

[0075] Rotary assembly 21 includes rotary wheel 213 rotationally connected at the outer wall of the sliding block 212, provides 411 under the pressure of the cable so that the rotating strip 412 rotates, the rotating rotating strip 412 pushes the sliding rod 323, and the positioning rod 322 is inclined, the inclined positioning rod 322 is in contact with the curved part of the cable, which changes the sliding friction of the cable in the curved state into rolling friction, which reduces the resistance when laying the cable, and prevents the cable in the curved state from scratching the two sides of the sliding column 13 and the fixed column 15, so that the protective layer on the outer wall of the cable is damaged.

[0076] Control assembly 22 includes positioning column 223 fixedly connected at the outer wall of the clamping block 312, the outer wall of the positioning column 223 is rotationally connected with the inner wall of the connecting rod 222,

[0077] Among them, when the staff rotates the rotating rod 211, the rotating disc 221 rotates, the rotating rotating disc 221 pulls the clamping block 312 to retract, so that the device is unlocked, so that the staff can move the positioning mechanism 2 and the locking mechanism 3 up and down, when adjusted to the appropriate position, the staff releases the rotating rod 211, the torsional spring inside the rotating rod 211 and the sliding block 212 releases the elastic potential energy when the staff releases his hand, so that the rotating rod 211 rotates again, the rotating rotating rod 211 makes the rotating disc 221 also start to rotate, at this time the rotation of the rotating disc 221 is completed, the connecting rod 222 returns to the horizontal state, and the clamping block 312 reenters the clamping slot 313 for locking.

[0078] Locking assembly 31 includes a plurality of clamping slots 313 opened in the inner wall of the sliding column 13;

[0079] Wherein, in the initial state, the card block 312 is clamped into the card slot 313, so that the device is in the locked state, rotating the rotating rod 211 makes the card block 312 disengage from the card slot 313, so that the device is in the unlocked state, so that the positioning mechanism 2 and the locking mechanism 3 can move up and down. When 411 is subjected to cable pressure, thereby rotating the rotating bar 412, allowing the rotating rotating bar 412 to push the slide rod 323, so that the positioning rod 322 is inclined, and the positioning rod 322 in the inclined state will make the roller 324 adhere to the curved part of the cable, which will make the sliding friction of the cable in the curved state change into rolling friction, which reduces the resistance when laying the cable, and prevents the cable in the curved state from scratching the two sides of the sliding column 13 and the fixed column 15, so that the protective layer on the outer wall of the cable is damaged

[0080] The rolling assembly 32 comprises a protrusion 321 slidingly connected to the outer wall of the fixed column 15, and two slide rods 323 are fixedly connected to the outer wall of the fixed column 15.

[0081] Wherein, the rolling assembly 32, the contact piece and the thrust mechanism 4 on the protrusion 321 on the outer wall of the fixed column 15 are connected in the same way as the protrusion 321 on the sliding column 13.

[0082] The pushing assembly 41 comprises two rotating bars 412 rotatably connected to the outer wall of the protrusion 321, and two push rods 411 are slidingly connected to the outer wall of the protrusion 321, and a plurality of rollers 413 are rotatably connected to the outer wall of the push rod 411.

[0083] Wherein, the positions of the pushing assembly 41 on the protrusion 321 are symmetrical to each other, when the push rod 411 is subjected to extrusion, the protrusion at the bottom of the push rod 411 will make the rotating bar 412 rotate, and the rotating rotating bar 412 will make the slide rod 323 move along the sliding groove on the protrusion 321, so that the positioning rod 322 is inclined, and at this time, the roller 324 will also be inclined to support the curved cable

[0084] The telescopic assembly 42 comprises a positioning bar 421 fixedly connected to the inner wall of the protrusion 321, and a stretching block 422 is slidingly connected to the inner wall of the positioning bar 421, and the push rod 411 is fixedly connected to the end of the stretching block 422 away from the positioning bar 421.

[0085] Wherein, a spring is fixedly connected inside the positioning bar 421, and the other end of the spring is fixedly connected with the stretching block 422, when the push rod 411 is subjected to pressure movement, the stretching block 422 will compress the spring inside the positioning bar 421, and the spring inside the positioning bar 421 will accumulate potential energy, when there is no cable on the roller 324, the potential energy accumulated by the positioning bar 421 will make the 411 reset.

[0086] One specific application of the embodiment is: when preparing, the staff first rotates the rotating rod 211, so that the rotating disc 221 rotates. The rotating rotating disc 221 will drive the connecting rod 222 to stretch the clamping block 312. The stretched protrusion 321 will be separated from the inside of the clamping groove 313. In this way, the staff can adjust the position of the front and rear rollers 324 up and down, which can speed up the adjustment speed of the staff, save the setting time, and fundamentally eliminate the problem of thread jamming caused by silt and rust, and reduce the maintenance difficulty.

[0087] After the staff adjusts the distance of the rollers 324, the cable can be placed on the outer wall of the rollers 324. Then, the staff rotates the rocker 18, so that the transmission belts 16 on both sides contact the surface of the cable. When the adjustment is completed, the staff can start the motor 17, so that the transmission belts 16 on both sides begin to rotate and transport the cable.

[0088] When laying in the field, the terrain needs to adapt to the ups and downs. At this time, the cable will have a height difference. The appearance of this height difference in the field changes the stress state of the cable. The cable needs to overcome its own gravity along the component force in the upward direction of the slope. The greater this height difference is, the greater this component force is. At this time, the motor 17 in the device may overheat due to excessive load, causing the motor 17 to trip or even burn out. At the same time, it will also cause wear and tear of the transmission belt 16 and damage to the cable sheath. By rotating the rotating rod 211, the torsional spring between the rotating rod 211 and the slider 212 will accumulate potential energy at this time. The rotating rotating disc 221 drives the connecting rod 222 to pull the clamping block 312 away from the inside of the clamping groove 313, so that the staff adjusts the rollers 324, and the rollers 324 move up and down with the protrusions 321 and the sliders 212. When adjusted to the appropriate position, the staff releases the rotating rod 211. The torsional spring between the rotating rod 211 and the slider 212 will release the elastic potential energy when the staff releases his hand, so that the rotating rod 211 rotates again. The rotating rotating rod 211 will make the rotating disc 221 also start to rotate. At this time, the rotation of the rotating disc 221 is completed, and the connecting rod 222 will return to the horizontal state. The clamping block 312 will re-enter the clamping groove 313 to be locked. By adjusting the front and rear rollers 324 up and down in this way, a smooth vertical bending path for the cable can be created, so that its path is lifted and guided. This reduces the resistance during laying, reduces the energy consumption of the equipment, and greatly reduces the risk of slipping of the conveyor caused by excessive resistance.

[0089] When the cable is close to the push rod 411, it will cause the push rod 411 to produce a lateral displacement, the bottom bump of the lateral displacement push rod 411 will cause the rotating bar 412 to rotate, the rotating rotating bar 412 will push the sliding rod 323, the pushed sliding rod 323 will move upwards along the notch on the bump 321, causing the positioning rod 322 to tilt, which will actively guide the cable to be inclined upwards when a horizontal turn is needed, forming a natural vertical bend, providing a support force for the cable in the curved state, preventing the bending of the cable from being aggravated during transportation, causing great damage to the cable body. After the laying is completed, there is no cable on the roller 324, at this time the push rod 411 will not be under pressure, then through the stretching block 422, the potential energy accumulated in the compression positioning bar 421 internal spring will reset the push rod 411.

[0090] When 411 is under the pressure of the cable, the rotating bar 412 is rotated, the rotating rotating bar 412 pushes the sliding rod 323, the positioning rod 322 is tilted, and the tilted positioning rod 322 will make the roller 324 adhere to the curved part of the cable, which will change the sliding friction of the cable in the curved state into rolling friction, which reduces the resistance when laying the cable, and prevents the cable in the curved state from scratching the two sides of the sliding column 13 and the fixed column 15, causing the protective layer on the outer wall of the cable to be damaged.
