Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, in particular to a pipeline laying device for electric power construction. Background Art

[0002] Pipeline laying devices for power construction are usually used for laying wires or cables over longer distances. The purpose is to carry out efficient power construction and save labor costs.

[0003] The patent with patent announcement number CN221759147U relates to the field of wire laying technology, including a main board, and a limiting transport mechanism is provided on the upper part of the main board. The limiting transport mechanism includes two symmetrical first support plates fixedly connected to the upper surface of the main board. This patent can be achieved by setting a servo motor. The servo motor can better drive the mechanism components to operate, so that the threaded rod has a threaded relationship with the slip ring when rotating, thereby driving the slip ring to move back and forth horizontally, making it convenient to limit the movement of the wire through the wire baffle, so that the wire can move synchronously with the position of the winding wheel to convey the wire, thereby effectively avoiding the risk of wire entanglement during laying, and also improving the stability during wire laying, avoiding wire entanglement affecting the wire laying process.

[0004] The above patent solves the problem of wire entanglement during the laying process of the device, which can effectively improve the overall construction efficiency during laying. However, during the laying process, as the cables are used less and less, to a certain extent, the shaft speeds in the front and rear pillars may become out of sync, causing tensile stress to accumulate inside the cables. At the same time, the cable replacement and wiring operations after the cables are used up are complicated. Summary of the Invention

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a pipeline laying device for power construction, including a base, a pillar 1 is fixedly installed on the front of the top of the base, a pillar 2 is fixedly installed on the back of the top of the base, a cable shaft is rotatably passed through the side of the pillar 2, a motor is fixedly installed on the top of the base, a double-layer pulley is fixedly installed on the output end of the motor, a pulley 2 is fixedly installed on the side of the cable shaft, a pulley 3 is rotatably installed on the side of the pillar 1, a wire outlet device is provided between the pillars 1, the wire outlet device includes a wire pressing slider, a conical roller, an arc roller 1 and a sliding rod, the conical roller is rotatably installed between the pillars 1, The sliding rod is fixedly installed between the pillars, the wire pressing slider is slidably installed on the circumferential surface of the sliding rod, the arc roller is rotatably installed at the bottom of the wire pressing slider, a telescopic top rod is fixedly installed on the top of the base, an arc support is fixedly installed on the top of the free end of the telescopic top rod, a pulley group is provided on the top of the base, a thin steel wire rope is fixedly installed on the bottom of the arc support, and one end of the thin steel wire rope away from the arc support is fixedly installed on the side of the wire pressing slider, thereby realizing the synchronization of the rotation speed between the cable shaft and the wire outlet device under different conditions, avoiding the accumulation of tensile stress inside the cable due to the lack of synchronization between the rotation speed of the wire outlet device and the cable on the cable shaft, thereby reducing the risk of cable breakage.

[0007] According to the above technical solution, the wire-out device also includes an arc roller 2, a roller bracket, a sliding card rod, a button switch, a guide rail slot and a limit slot. The roller bracket is fixedly installed at the bottom of the wire-pressing slider, the arc roller 2 is slidably installed in the middle of the roller bracket, the guide rail slot is fixedly installed on the top of the roller bracket, the limit slot is fixedly installed on one side of the arc roller, the sliding card rod is slidably installed on the bottom inside the wire-pressing slider, and the button switch is fixedly installed on the bottom inside the wire-pressing slider. When the device is in operation, when the cable is out of contact with the arc roller 2, the tightening spring drives it to tighten toward the middle and squeeze the rear end of the sliding card rod. After the rear end of the sliding card rod is squeezed, its front end moves forward to squeeze the button switch and jam the limit slot, thereby realizing the emergency stop of the device when the cable is exhausted, avoiding the continuous operation of the device after the cable is exhausted, resulting in the falling of the wire end, and facilitating the wiring work in subsequent work.

[0008] According to the above technical solution, a limited length groove is opened in the middle of the wire-pressing slider, the sliding rod slides through the wire-pressing slider, a reset spring is arranged between the wire-pressing slider and the sliding rod, the button switch is electrically connected to the motor, and the sliding rod slides through the wire-pressing slider so that it can slide left and right along the sliding rod, thereby realizing that the cable can slide left and right along the conical surface of the conical drum when the cable is discharged.

[0009] According to the above technical solution, a push rod is fixedly installed on the back of the top of the base, a universal wheel is fixedly installed on the bottom of the base, and a spring is arranged inside the telescopic top rod. The push rod and the universal wheel can make the device move more flexibly during use, so that it can adapt to construction work on various road surfaces. The elastic force exerted by the spring can make the arc-shaped support fixedly installed on the top of the free end of the telescopic top rod always in contact with the cable on the cable shaft, realizing real-time monitoring of the remaining length of the cable.

[0010] According to the above technical solution, a braking device is provided on the top of the base, a slotted gasket is rotatably installed on the circumferential surface of the telescopic top rod, a bracket lever is fixedly installed on the top of the base, a hydraulic cylinder is fixedly installed inside the base, piston rod one is slidably installed on one side of the hydraulic cylinder, and piston rod two is slidably installed on the other side of the hydraulic cylinder, a rotatable tripod is rotatably installed on the bottom of the base, and a curved top block is fixedly installed on the rear part of the piston rod two.

[0011] According to the above technical solution, one end of the bracket lever contacts the slotted gasket, the other end of the bracket lever contacts the top of the piston rod, a rubber pad is fixedly installed at the bottom of the rotatable tripod, a block is fixedly installed at the bottom of the base, and a return spring is arranged between the rotatable tripod and the base. The return spring can make the device return to the working state more conveniently and quickly after being supported by the rotatable tripod, and at the same time prevent the rotatable tripod from supporting the device after contacting the ground during normal operation.

[0012] According to the above technical solution, a tightening spring is arranged between the rotating shafts of the arc-shaped roller 2, the top of the rotating shaft of the arc-shaped roller 2 is slidably connected to the inside of the guide rail groove, the top of the rotating shaft of the arc-shaped roller 2 is fixedly connected to the two ends of the rear part of the sliding card rod, and a reciprocating rotating shaft is arranged in the middle of the sliding card rod. The guide rail groove makes the movement of the arc-shaped roller 2 smoother after being squeezed to prevent its movement trajectory from deviating. The reciprocating rotating shaft enables the sliding card rod to move its front end forward when it is squeezed at its rear.

[0013] According to the above technical solution, the pulley two is connected to the double-layer pulley through the belt one, and the pulley three is connected to the double-layer pulley through the belt two. One of the pillars is provided with a roll-changing chute, and the roll-changing chute is slidably installed with an anti-slip protective shell on the side close to the cable shaft. When the cables are all used up and the wire roll needs to be replaced, the anti-slip protective shell is removed from the side and the cable shaft is taken out along the roll-changing chute. Subsequently, the new wire roll is installed on the device along the roll-changing chute and the anti-slip protective shell is buckled on the side. The operation of directly changing the roll after the cable is used up greatly improves the continuous construction efficiency.

[0014] The present invention provides a pipeline laying device for electric power construction, which has the following beneficial effects: (1) This invention, when working continuously, uses an arc-shaped support and a thin steel wire rope to drag the wire pressing slider to the right, and the cross-sectional diameter of the cable in contact with the conical drum gradually decreases, that is, the linear speed of the conical drum decreases, thereby reducing the speed at which the outlet device releases the cable, thereby achieving synchronization of the rotation speeds of the cable shaft and the outlet device under different conditions, avoiding the accumulation of tensile stress inside the cable due to the lack of synchronization between the rotation speed of the cable shaft and the outlet device when the cable is used up, thereby reducing the risk of cable breakage.

[0015] (2) In this invention, when the cable is separated from the arc drum, the tightening spring drives the arc drum to shrink toward the middle and squeeze the sliding card rod. After the rear part of the sliding card rod is squeezed, its front end moves forward to squeeze the button switch and jam the limit card slot, thus realizing emergency braking when the cable is about to run out during operation, avoiding the cable end being separated due to the device still running after the cable is used up, thereby facilitating the replacement of the wire reel during construction and the wiring work after the replacement.

[0016] (3) In this invention, when the cable on the cable shaft is about to run out after the device has been working continuously, the telescopic top rod is extended to the longest position, driving the front end of the bracket lever to move downward, thereby causing the second piston rod to extend and contact the rotatable tripod to prop up the entire device. This enables the device to stop working when the cable is exhausted, and at the same time props up the rear of the device to facilitate the replacement of the wire reel during subsequent work.

The wire outlet device includes a wire pressing slider 1401, a conical roller 1402, an arc roller 1403 and a sliding rod 1410. The conical roller 1402 is rotatably installed between the pillars 1 2, and the sliding rod 1410 is fixedly installed between the pillars 1 2. 1401 is slidably installed on the circumferential surface of the sliding rod 1410, and the arc-shaped roller 1403 is rotatably installed at the bottom of the wire-pressing slider 1401. A telescopic top rod 1101 is fixedly installed on the top of the base 1, and an arc-shaped support platform 1102 is fixedly installed on the top of the free end of the telescopic top rod 1101.

The end of the thin steel wire rope 13 away from the arc support platform 1102 is fixedly installed on the side of the wire-pressing slider 1401, realizing the synchronization of the rotation speed between the cable shaft 4 and the wire-out device under different conditions, avoiding the accumulation of tensile stress inside the cable due to the asynchronous rotation speed of the wire-out device when the cable on the cable shaft 4 is used less and less, thereby reducing the risk of cable breakage.

[0021] The wire outlet device also includes an arc roller 1404, a roller bracket 1405, a sliding card rod 1406, a button switch 1407, a guide groove 1408 and a limit card slot 1409. The roller bracket 1405 is fixedly installed at the bottom of the wire pressing slider 1401, the arc roller 1404 is slidably installed in the middle of the roller bracket 1405, the guide groove 1408 is fixedly installed on the top of the roller bracket 1405, the limit card slot 1409 is fixedly installed on the side of the arc roller 1403, and the sliding card rod 1406 is slidably installed on the wire pressing slider 1401. At the bottom of the interior, the button switch 1407 is fixedly installed at the bottom of the wire pressing slider 1401.

After the rear of the sliding card rod 1406 is squeezed, its front end moves forward to squeeze the button switch 1407 and jam the limit card slot 1409, realizing the emergency stop of the device when the cable is exhausted, avoiding the continuous operation of the device after the cable is exhausted, causing the wire end to fall off, and facilitating the wiring work in subsequent work.

[0022] A limited length slot is provided in the middle of the wire-pressing slider 1401, and the sliding rod 1410 slides through the wire-pressing slider 1401. A reset spring is provided between the wire-pressing slider 1401 and the sliding rod 1410. The button switch 1407 is electrically connected to the motor 6. The sliding rod 1410 slides through the wire-pressing slider 1401 so that it can slide left and right along the sliding rod 1410, thereby enabling the cable to slide left and right along the conical surface of the conical roller 1402 when the cable is discharged.

[0023] A push rod 5 is fixedly installed on the back of the top of the base 1, a universal wheel 10 is fixedly installed on the bottom of the base 1, and a spring is provided inside the telescopic top rod 1101. The push rod 5 and the universal wheel 10 can make the device move more flexibly during use, making it adaptable to construction work on various road surfaces. The elastic force exerted by the spring can make the arc-shaped support 1102 fixedly installed on the top of the free end of the telescopic top rod 1101 always in contact with the cable on the cable shaft 4, realizing real-time monitoring of the remaining length of the cable.

[0024] A braking device is provided on the top of the base 1, and a slotted gasket 1103 is rotatably installed on the circumferential surface of the telescopic top rod 1101. A bracket lever 1104 is fixedly installed on the top of the base 1, and a hydraulic cylinder 1107 is fixedly installed inside the base 1. Piston rod 1 1105 is slidably installed on one side of the hydraulic cylinder 1107, and piston rod 2 1106 is slidably installed on the other side of the hydraulic cylinder 1107. A rotatable tripod 1108 is rotatably installed on the bottom of the base 1, and a curved top block is fixedly installed on the rear of piston rod 2 1106. The braking device enables the device to stop working when the cable is exhausted, and at the same time props up the rear of the device to facilitate the replacement of the wire reel during subsequent work.

[0025] One end of the bracket lever 1104 contacts the slotted gasket 1103, and the other end of the bracket lever 1104 contacts the top of the piston rod 1105. A rubber pad is fixedly installed at the bottom of the rotatable tripod 1108, and a block is fixedly installed at the bottom of the base 1. A return spring is arranged between the rotatable tripod 1108 and the base 1. The return spring can make the device return to the working state more conveniently and quickly after being supported by the rotatable tripod 1108, and at the same time prevent the rotatable tripod 1108 from supporting the device after contacting the ground during normal operation.

[0026] A tightening spring is arranged between the rotating shafts of the arc roller 2 1404, and the top of the rotating shaft of the arc roller 2 1404 is slidably connected to the inside of the guide groove 1408. The top of the rotating shaft of the arc roller 2 1404 is fixedly connected to the two ends of the rear part of the sliding card rod 1406. A reciprocating rotating shaft is arranged in the middle of the sliding card rod 1406. The guide groove 1408 makes the movement of the arc roller 2 1404 smoother after being squeezed to prevent its movement trajectory from deviating. The reciprocating rotating shaft enables the sliding card rod 1406 to move its front end forward when it is squeezed at its rear.

[0027] The pulley 2 8 is connected to the double-layer pulley 7 through the belt 1 transmission, and the pulley 3 9 is connected to the double-layer pulley 7 through the belt 2 transmission. One of the pillars 1 2 is provided with a roll-changing chute, and the roll-changing chute is slidably installed with an anti-slip protective shell on the side close to the cable shaft 4. When the cable is completely used up and the wire roll needs to be replaced, the anti-slip protective shell is removed from the side and the cable shaft 4 is taken out along the roll-changing chute, and then the new wire roll is installed on the device along the roll-changing chute and the anti-slip protective shell is buckled from the side. The operation of directly changing the roll after the cable is used up greatly improves the continuous construction efficiency.

[0028] During operation: When the device is started, the motor 6 is started, and the output end of the motor 6 drives the double-layer pulley 7 to rotate clockwise when viewed from the left. The double-layer pulley 7 drives the pulley 2 8 to rotate through the belt, and the rotation of the pulley 2 8 drives the cable shaft 4 to rotate. The rotation of the cable shaft 4 drives the cable installed on its circumferential surface to rotate and output the wire.

[0029] The cable, which is drawn from cable shaft 4, contacts the curved surface of curved roller 2 1404, exerting a thrust that spreads outward from the center of the two rollers. This stretches the take-up spring on the rotating shaft of curved roller 2 1404, causing it to pass through curved roller 2 1404 and then contact the curved surface of curved roller 1 1403 and the conical surface of conical roller 1402. Double-layer pulley 7 rotates pulley 3 9 via a belt, which in turn rotates conical roller 1402. The friction generated by the contact between the cable and the pulley drives the cable forward and out.

[0030] When the device is under continuous construction, less and less cable is used, that is, the diameter of the cable wound on the cable shaft 4 will become smaller and smaller. When the cable is about to be laid, the telescopic top rod 1101 moves linearly upward due to the elastic force generated by the compression of the internal spring. The movement of the telescopic top rod 1101 drives the arc support 1102 to move upward. The arc support 1102 contacts the cable. The movement of the telescopic top rod 1101 drives the slotted gasket 1103 to move upward. When the slotted gasket 1103 moves, it drives it to move upward by contacting the rear end of the bracket lever 1104. At the same time, the front end of the bracket lever 1104 moves downward. The front end of the bracket lever 1104 moves downward and drives the piston rod 1105 to move downward by contact. When the piston rod 1105 moves downward, it squeezes The hydraulic oil in the hydraulic cylinder 1107 drives the piston rod 2 1106 to extend and move backward. The movement of the piston rod 2 1106 drives the curved top block to move. The curved top block drives it to rotate downward by contacting the rotatable tripod 1108. When the bottom of the rotatable tripod 1108 touches the ground, the entire device is pushed forward. The friction caused by the contact between the rotatable tripod 1108 and the ground causes it to rotate further until it contacts the block, thereby supporting the rear of the base 1. The two universal wheels 10 at the rear of the base 1 are out of contact with the ground, so that the device stops working in time when the cable is about to run out during the laying process. At the same time, the rotatable tripod 1108 supports the base 1, which facilitates the subsequent line changing process and improves the overall work efficiency and user experience of the device.

[0031] When the arc-shaped support platform 1102 moves upward, it will drive one end of the thin steel wire rope 13 to move upward, and the thin steel wire rope 13 will pass around the pulley group 12, and the other end of the wire rope will drive the wire pressing slider 1401 to move toward the right. The wire pressing slider 1401 moves toward the right, driving the arc roller 1403 to move toward the right. The arc roller 1403 drives the cable to move toward the right by contacting the cable. When the cable moves toward the right, the diameter of the cross-section of the contact point with the conical roller 1402 becomes smaller and smaller, and the line produced by the conical roller 1402 rotating one circle becomes shorter and shorter, which is synchronized with the fact that the cable on the cable shaft 4 is used less and less, and the line produced by rotating one circle becomes shorter and shorter. In this way, the synchronization of line output under different conditions is achieved, and the accumulated tensile stress inside the cable caused by the asynchronous line output is avoided, which leads to cable breakage, thereby improving the safety of construction workers during construction.

[0032] When all the cables are used up during the laying process, that is, the cables are out of contact with the arc roller 2 1404, the tightening springs between the rotating shafts of the arc roller 2 1404 are tightened, driving the rear ends of the sliding card rod 1406 to tighten toward the middle, thereby driving the front part of the sliding card rod 1406 to move forward. When it moves forward, the bottom contacts the button switch 1407 and is pressed. The button switch 1407 connects to the motor 6 and stops the motor 6. At the same time, the front end of the sliding card rod 1406 contacts the limit slot 1409 to jam it. The limit slot 1409 is jammed to stop the arc roller 1 1403 from rotating, realizing an emergency stop of the device after all the cables are used up, preventing the cable from being detached from the device due to the device not stopping in time, thereby optimizing the wiring operation during subsequent construction.

[0033] The device continues to work until the cable is completely used up, the anti-slip protective cover is removed from the side and the cable shaft 4 is slid out along the roll-changing chute, and then the new wire roll is installed on the device along the roll-changing chute and the anti-slip protective cover is buckled from the side, and the wire end of the new wire roll is guided through the arc roller 2 1404 and passes between the conical roller 1402 and the arc roller 1 1403 to realize the cable connection after the roll change.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
