Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a pipeline laying traction device for water conservancy construction. Background Art

[0002] During the construction of water conservancy projects, it is necessary to control and allocate natural water resources, so it is necessary to lay pipelines to transport water resources. During the pipeline laying process, since the pipelines are large in size and need to be laid continuously, in order to reduce the labor intensity of the staff, external traction equipment is required.

[0003] The patent with the patent announcement number CN216582289U discloses a traction device for laying water conservancy pipelines, which belongs to the field of water conservancy engineering technology, and includes a support plate, a roller and a conveying frame. The roller is rotatably mounted at the bottom of the support plate, and the conveying frame is arranged above the support plate. The conveying frame is rotatably connected to a conveying roller, and the conveying frame is provided with an adjustment mechanism for adjusting the tilt angle. The patent can reduce the friction between the water conservancy pipeline and the conveying frame by arranging the conveying roller, so that the water conservancy pipeline can be easily unloaded from the transportation tool, thereby improving the efficiency of laying the water conservancy pipeline.

[0004] However, this device still has shortcomings: this device can reduce the friction between the water conservancy pipeline and the transportation tool, but when the water conservancy pipeline is made of materials such as cast steel or concrete, due to the large overall mass of the pipeline, the impact force generated during the pulling process of the pipeline is large, which can easily cause a large impact on the unloading part of the equipment, and then easily lead to insufficient buffering force, thereby increasing the possibility of uncontrollable risks when pulling the pipeline. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a pipeline laying traction device for water conservancy construction, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a pipeline laying traction device for water conservancy construction, including a conveying platform, a hollow platform is arranged on the right side of the top of the conveying platform, a buffer pad is arranged inside the hollow platform through a spring, a discharge plate is arranged on the right side of the hollow platform, a hydraulic rod is arranged on the left side of the top of the conveying platform, a slider is arranged on the top of the telescopic end of the hydraulic rod, a feeding platform is arranged on the top of the slider, the right side of the feeding platform is hinged to the left side of the hollow platform, and a conveying roller is arranged inside the feeding platform; A deceleration device is symmetrically arranged on the left side of the top of the conveying platform, a centering device is arranged on the right side of the deceleration device, and an auxiliary device is arranged on the periphery of the centering device; The speed reduction device includes two fixed plates, the bottoms of the two fixed plates are symmetrical and fixedly installed on the left side of the top of the conveying platform, a transmission rod is rotatably installed on the fixed plate close to the axis of the conveying platform, the outer wall of the reciprocating spiral groove of the transmission rod passes through and a baffle is movably installed, the bottom of the baffle is slidably installed at the top edge of the conveying platform, the baffle is hinged with an elastic telescopic plate on the side close to the axis of the conveying platform through a torsion spring, the top of the telescopic end of the elastic telescopic plate is hinged with a supporting ladder plate, a telescopic arc plate is fixedly installed on the top of one end of the baffle close to the axis of the conveying platform, a hollow arc frame is fixedly installed on the telescopic end of the telescopic arc plate close to the axis of the conveying platform, and a plurality of arc surface blocks are slidably installed inside the hollow arc frame through springs.

[0007] According to the above technical solution, reciprocating spiral grooves are symmetrically provided at both ends of the transmission rod, the top of the supporting ladder plate is located on the motion trajectory of the bottom of the feed table, and a number of the arc blocks are equidistantly distributed inside the hollow arc frame, and the pipeline is placed horizontally on the conveying roller of the feed table, and then the telescopic end of the hydraulic rod moves upward to push the slider, and the slider pushes the feed table to move synchronously, and the feed table limits the slider through the position of the feed table, so that the hinge shaft of the telescopic end of the hydraulic rod starts to rotate, and at this time the hinge shaft between the right end of the feed table and the hollow table starts to rotate, and at this time the feed table flips upward in an arc-shaped trajectory with the hinge shaft as the axis until it tilts to Figure 1 The displayed posture stops, and when the feeding table flips, it drives the conveying roller to move synchronously. The conveying roller conveys the pipe on its outer wall in an inclined posture to slide close to the buffer pad. When the pipe slides to the top of the buffer pad, it relies on the spring and the elasticity of the buffer pad to buffer. At the same time, the unloading plate flips downward with the hinge shaft as the axis to contact the ground, which is convenient for unloading the pipe. At the same time, before pulling the pipe, the transmission rod is started, and the transmission rod is kept stationary by the fixed plate limit. When the transmission rod rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the baffle, driving the baffle to slide along the top edge of the conveying table close to its axis. When the baffle slides horizontally, it drives the elastic telescopic plate to move synchronously, and the telescopic end of the elastic telescopic plate drives the supporting ladder plate to move synchronously. The limit causes the hinge shaft at the top of the telescopic end of the elastic telescopic plate to start rotating. At this time, the elastic telescopic plate will push the supporting ladder plate to move upward; when the baffle moves toward the center of the conveyor platform, it drives the telescopic arc plate to move synchronously, the telescopic arc plate drives the hollow arc frame to move synchronously, and the hollow arc frame drives the arc surface block to move synchronously. The arc surface of the arc surface block will contact the outer wall of the pipe falling from the surface of the conveying roller to generate a resistance force. At this time, the arc surface block slides into the hollow arc frame. When the openings at both ends of the pipe pass through the arc surface block, the arc surface block is reset by the spring until the inner walls of the openings at both ends of the pipe contact the arc surface block again to generate a resistance force. At the same time, when the length of the pipe is long, when the arc surface block slides to the limit inside the hollow arc frame, the hollow arc frame will push the telescopic end of the telescopic arc plate to contract for size adjustment.

[0008] According to the above technical solution, the centering device includes a sliding plate, a through plate and a single-sided arc plate. The left end of the sliding plate is fixedly installed on the right side of the fixed end of the telescopic arc plate. The outer wall of the through plate penetrates and is slidably installed inside the sliding plate. The single-sided arc plate is fixedly installed on the outer wall of the through plate close to one side of the sliding plate.

[0009] According to the above technical scheme, the bottom of the sliding plate is slidably installed at the top edge of the conveying platform, and a U-shaped groove is opened at the center of the bottom end of the sliding plate, a spring is arranged between the outer wall of the through plate and the inside of the sliding plate, and the angle of the outer wall of the single-sided arc plate gradually increases from left to right. When the fixed end of the telescopic arc plate slides toward the center of the conveying platform, the fixed end of the telescopic arc plate drives the sliding plate to move synchronously along the conveying platform, the sliding plate drives the through plate to move synchronously, and the through plate drives the single-sided arc plate to move synchronously. When the single-sided arc plate moves toward the center of the buffer pad, it will contact the outer walls of both ends of the pipe that is pulled down, and the arc surface of the single-sided arc plate contacts the outer walls of both ends of the pipe to generate a resistance force. At this time, when the single-sided arc plate pushes the through plate to move away from the center of the buffer pad, it is limited by the spring, and the single-sided arc plates on both sides move synchronously to clamp the pipe, and at the same time, the single-sided arc plate limits the pipe away from the feeding platform.

[0010] The L-shaped telescopic impact plate is fixedly mounted on the outer wall of the sliding plate near the side of the single-sided arc plate, and a square groove is provided at the telescopic end of the L-shaped telescopic impact plate. Both ends of the cross bar are fixedly mounted inside the square groove at the telescopic end of the L-shaped telescopic impact plate. The inside of the flip plate is penetrated by a torsion spring and hinged at the outer wall of the cross bar. The vertical bar is fixedly mounted between the top of the telescopic end of the L-shaped telescopic impact plate and the bottom of the single-sided arc plate. Several friction wheels are symmetrically and rotatably mounted inside the U-shaped groove of the sliding plate. The outer wall of the friction wheel is When the sliding plate contacts the top of the conveyor platform, it drives the friction wheel to move synchronously along the top of the conveyor platform when it moves toward the center of the buffer pad, and the friction wheel starts to rotate due to the friction force during movement, and the sliding plate drives the L-shaped telescopic impact plate to move synchronously when it slides, and the L-shaped telescopic impact plate drives the cross bar to move synchronously, and the cross bar drives the flip plate to move synchronously, and the telescopic end of the L-shaped telescopic impact plate synchronizes with the vertical rod and the single-sided arc plate to achieve synchronous movement, and the outer wall of the top of the flip plate contacts the pipeline before the telescopic end of the L-shaped telescopic impact plate, which will generate resistance force, and the flip plate starts to flip along the outer wall of the cross bar due to the resistance force, and the flip plate is limited by the torsion spring to generate reverse thrust to reset.

[0011] The ferrule slide plate is an L-shaped slide plate with a plurality of movable parts, and the movable part is an L-shaped slide plate with a plurality of movable parts.

[0012] According to the above technical scheme, the auxiliary device also includes a contact plate, an L-shaped arc panel, a U-shaped frame, a friction frame and an arc block. The contact plate is fixedly installed on the outer wall of the ring slide plate close to the side of the penetration plate, and the L-shaped arc panel is slidably installed on the outer wall of the sliding plate close to the side of the penetration plate through a spring. The outer wall of the bottom end of the U-shaped frame penetrates and is hinged inside the L-shaped arc panel. Both ends of the friction frame are hinged to the inside of the top of the U-shaped frame through torsion springs, and the outer wall of the arc block is slidably installed inside the friction frame through a longitudinal spring.

[0013] The L-shaped arc panel is connected to the upper and lower surfaces of the L-shaped arc panel, and the upper and lower surfaces of the L-shaped arc panel are connected to each other.

[0014] The present invention provides a pipeline laying traction device for water conservancy construction, which has the following beneficial effects: (1) The present invention sets a deceleration device, and cooperates with a fixed plate, a transmission rod, a baffle, an elastic telescopic plate, a support ladder plate, a telescopic arc plate, a hollow arc frame and an arc surface block. The friction between the pipeline and the equipment is effectively reduced by the conveying roller and the buffer pad, thereby reducing the probability of wear. At the same time, the support ladder plate is used to support the bottom of the feed table in an inclined posture. When the pipeline is heavy and causes the telescopic end of the hydraulic rod to shrink downward or be damaged, the support ladder plate is used to support the feed table, and the elastic end of the elastic telescopic plate is used to reduce the speed of the fall through the spring force built into the telescopic end of the elastic telescopic plate, so that the telescopic end of the hydraulic rod can be slowly reset to reduce pipeline fluctuations, thereby effectively preventing the pipeline from falling directly during the traction process; at the same time, the arc surface block is used to reciprocate and retract and reset to achieve continuous deceleration of the pipeline falling speed, thereby avoiding the pipeline from generating a large impact force during the traction process due to its large overall mass, reducing the impact of the pipeline on the unloading plate, thereby improving the protection effect of the unloading plate, and reducing the risk generated when traction is performed on the pipeline.

[0015] (2) The present invention sets a centering device, and cooperates with telescopic arc plates, sliding plates, through plates, single-sided arc plates, L-shaped telescopic impact plates, cross bars, flip plates, vertical bars and friction wheels. The single-sided arc plates clamp the pipeline to ensure that it is always in a relatively central position when it falls to the top of the buffer pad, thereby preventing the pipeline from being in an inclined position after falling, thereby increasing the difficulty of unloading and the length of time required for laying. At the same time, the non-arc side of the single-sided arc plate limits the two ends of the pipeline to prevent the pipeline from rolling toward the feed table after falling; and the flipping process of the flip plate enables the outer wall of the flip plate to fit tightly against the outer wall of the two ends of the pipeline, thereby increasing the friction force when the telescopic end of the L-shaped telescopic impact plate contacts the pipeline, and improving the centering pushing effect of the L-shaped telescopic impact plate on the pipeline. At the same time, the telescopic end of the L-shaped telescopic impact plate moves synchronously with the single-sided arc plate, which will not hinder the traction work of the pipeline while achieving efficient centering pushing, thereby further optimizing the pipeline laying efficiency.

[0016] (3) The present invention sets an auxiliary device, and cooperates with the friction wheel, reciprocating screw, ring slide plate, vibration plate, contact plate, L-shaped arc plate, U-shaped frame, friction frame and arc block to make the L-shaped telescopic impact plate carry slight vibration and contact with the two ends of the pipeline. Similarly, the flip plate can increase the friction between itself and the two ends of the pipeline with slight vibration, further improving the centering pushing effect of the L-shaped telescopic impact plate on the pipeline on the original basis, and preventing the L-shaped telescopic impact plate from misaligning due to uneven force during the process of pushing the pipeline, thereby causing the pipeline to tilt in one direction; at the same time, the outer wall of the through-plate is actively scraped by the friction frame and the arc block to ensure the cleanliness of the bottom of the through-plate, and to avoid the through-plate from reducing the sliding smoothness inside the sliding plate due to dirt attached to the outer wall. When the through-plate is retracted by the pipeline, the friction frame and the arc block are in passive friction with the bottom of the through-plate, and the reciprocating movement makes the through-plate slide undisturbed, and prevents the through-plate from being blocked from slightly tilting due to the contraction, thereby reducing the centering pushing effect on the pipeline.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 9 One embodiment of the present invention is: a pipeline laying traction device for water conservancy construction, including a conveying platform 1, a hollow platform 2 is arranged on the right side of the top of the conveying platform 1, a buffer pad 21 is arranged inside the hollow platform 2 through a spring, a discharge plate 22 is arranged on the right side of the hollow platform 2, a hydraulic rod 3 is arranged on the left side of the top of the conveying platform 1, a slider is arranged on the top of the telescopic end of the hydraulic rod 3, a feed platform 31 is arranged on the top of the slider, the right side of the feed platform 31 is hinged to the left side of the hollow platform 2, and a conveying roller 32 is arranged inside the feed platform 31; A deceleration device 4 is symmetrically arranged on the left side of the top of the conveying platform 1, a centering device 5 is arranged on the right side of the deceleration device 4, and an auxiliary device 6 is arranged on the periphery of the centering device 5; The deceleration device 4 includes two fixed plates 41, the bottoms of the two fixed plates 41 are symmetrical and fixedly installed on the left side of the top of the conveyor platform 1, a transmission rod 42 is rotatably installed on the fixed plate 41 near the axis of the conveyor platform 1, and a baffle 43 is movably installed on the outer wall of the reciprocating spiral groove of the transmission rod 42, and the bottom of the baffle 43 is slidably installed at the top edge of the conveyor platform 1, and an elastic telescopic plate 44 is hingedly connected to the baffle 43 near the axis of the conveyor platform 1 through a torsion spring, and a support ladder plate 45 is hingedly connected to the top of the telescopic end of the elastic telescopic plate 44, a telescopic arc plate 46 is fixedly installed on the top end of the baffle 43 near the axis of the conveyor platform 1, and a hollow arc frame 47 is fixedly installed on the telescopic end of the telescopic arc plate 46 near the axis of the conveyor platform 1, and a plurality of arc surface blocks 48 are slidably installed inside the hollow arc frame 47 through springs.

[0021] Reciprocating spiral grooves are symmetrically provided at both ends of the transmission rod 42, the top of the support ladder plate 45 is located on the motion trajectory of the bottom of the feed platform 31, and a number of arc blocks 48 are equidistantly distributed inside the hollow arc frame 47. Through the above cooperation, the conveying roller 32 and the buffer pad 21 are effectively used to reduce the friction between the pipeline and the equipment, and the wear probability is reduced. At the same time, the support ladder plate 45 is used to support the bottom of the feed platform 31 in an inclined posture. When the pipeline is heavy and causes the telescopic end of the hydraulic rod 3 to shrink downward or be damaged, the support ladder plate 45 supports the feed platform 31, and the elastic elastic plate 44 is used to reduce the speed of the telescopic end of the elastic telescopic plate 44. The elastic end of the hydraulic rod 3 can be slowly reset to reduce pipeline fluctuations and effectively prevent the pipeline from falling directly during traction. Through the above cooperation, the arc block 48 is reciprocated to shrink and reset, so as to achieve continuous deceleration of the pipeline falling speed, avoid the pipeline from generating a large impact force during traction due to its large overall mass, reduce the impact of the pipeline on the unloading plate 22, thereby improving the protection effect of the unloading plate 22 and reducing the risk generated when traction of the pipeline.

[0022] When in use, the pipe is placed horizontally on the conveying roller 32 of the feed table 31, and then the telescopic end of the hydraulic rod 3 moves upward to push the slider, and the slider pushes the feed table 31 to move synchronously. The feed table 31 limits the slider, causing the hinge shaft of the telescopic end of the hydraulic rod 3 to start rotating. At this time, the hinge shaft between the right end of the feed table 31 and the hollow table 2 starts to rotate. At this time, the feed table 31 turns upward in an arc trajectory with the hinge shaft as the axis until it tilts to Figure 1The posture shown stops, and the feeding platform 31 drives the conveying roller 32 to move synchronously when it turns over. The conveying roller 32 conveys the pipe on its outer wall in an inclined posture to slide towards the buffer pad 21. When the pipe slides to the top of the buffer pad 21, it relies on the spring and the elasticity of the buffer pad 21 to buffer. At the same time, the unloading plate 22 turns downward with the hinge axis as the axis to contact the ground, which is convenient for unloading the pipe. At the same time, before pulling the pipe, the transmission rod 42 is started, and the transmission rod 42 is limited by the fixed plate 41 to remain stationary. When the transmission rod 42 rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the baffle 43, driving the baffle 43 along the top edge of the conveying platform 1 to When sliding near its axial direction, the baffle plate 43 slides horizontally, driving the elastic telescopic plate 44 to move synchronously, and the telescopic end of the elastic telescopic plate 44 drives the supporting ladder plate 45 to move synchronously, and the limit of the supporting ladder plate 45 causes the hinge shaft at the top of the telescopic end of the elastic telescopic plate 44 to start to rotate. At this time, the elastic telescopic plate 44 will push the supporting ladder plate 45 to move upward. Through the above cooperation, the conveying roller 32 and the buffer pad 21 are used to effectively reduce the friction between the pipeline and the equipment, reduce the probability of wear, and rely on the supporting ladder plate 45 to support the bottom of the feed table 31 in an inclined posture. When the pipeline is heavy and causes the telescopic end of the hydraulic rod 3 to shrink downward or be damaged, the support The ladder plate 45 supports the feed platform 31, and the elastic plate 44 is decelerated by the built-in spring force at the telescopic end to make it fall, so that the telescopic end of the hydraulic rod 3 can be slowly reset to reduce pipeline fluctuations, effectively preventing the pipeline from falling directly during traction; when the baffle plate 43 moves toward the center of the conveying platform 1, it drives the telescopic arc plate 46 to move synchronously, and the telescopic arc plate 46 drives the hollow arc frame 47 to move synchronously, and the hollow arc frame 47 drives the arc surface block 48 to move synchronously, and the arc surface of the arc surface block 48 will contact the outer wall of the pipeline falling from the surface of the conveying roller 32 to generate a resistance force. At this time, the arc surface block 48 slides into the hollow arc frame 47. When the openings at both ends of the pipeline pass through the arc surface block 48, the arc block 48 is reset by the spring until the inner walls of the openings at both ends of the pipeline contact the arc block 48 again to generate resistance. At the same time, when the pipeline is long, when the arc block 48 slides to the limit inside the hollow arc frame 47, the hollow arc frame 47 will push the telescopic end of the telescopic arc plate 46 to shrink for size adjustment. Through the above cooperation, the arc block 48 reciprocates and resetting, so as to realize the continuous deceleration of the falling speed of the pipeline, avoid the pipeline from generating a large impact force during the traction process due to the large overall mass, reduce the impact of the pipeline on the unloading plate 22, thereby improving the protection effect of the unloading plate 22, and reducing the risk generated when traction of the pipeline.

[0023] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a centering device 5; The centering device 5 includes a sliding plate 51, a through plate 52 and a single-sided arc plate 53. The left end of the sliding plate 51 is fixedly installed on the right side of the fixed end of the telescopic arc plate 46. The outer wall of the through plate 52 penetrates and is slidably installed inside the sliding plate 51. The single-sided arc plate 53 is fixedly installed on the outer wall of the through plate 52 close to one side of the sliding plate 51.

[0024] The bottom of the sliding plate 51 is slidably installed on the top edge of the conveyor platform 1, and a U-shaped groove is opened at the center of the bottom end of the sliding plate 51. A spring is arranged between the outer wall of the through plate 52 and the inside of the sliding plate 51. The outer wall angle of the single-sided arc plate 53 gradually increases from left to right. Through the above coordination, the pipe is clamped by the single-sided arc plate 53 to ensure that it is always in a relatively central position when it falls to the top of the buffer pad 21, so as to avoid the pipe from being tilted after falling, thereby increasing the difficulty of unloading and the length of laying time. At the same time, the non-arc side of the single-sided arc plate 53 limits the two ends of the pipe to prevent the pipe from rolling toward the feed platform 31 after falling.

[0025] The centering device 5 also includes an L-shaped telescopic impact plate 54, a cross bar 55, a flip plate 56, a vertical bar 57 and a plurality of friction wheels 58. The L-shaped telescopic impact plate 54 is fixedly installed on the outer wall of the sliding plate 51 near the side of the single-sided arc plate 53. A square groove is provided at the telescopic end of the L-shaped telescopic impact plate 54. Both ends of the cross bar 55 are fixedly installed inside the square groove at the telescopic end of the L-shaped telescopic impact plate 54. The flip plate 56 is penetrated by a torsion spring and is hinged at the outer wall of the cross bar 55. The vertical bar 57 is fixedly installed between the top of the telescopic end of the L-shaped telescopic impact plate 54 and the bottom of the single-sided arc plate 53. The plurality of friction wheels 58 are 8 are symmetrically and rotatably installed inside the U-shaped groove of the sliding plate 51, and the outer wall of the friction wheel 58 is in contact with the top of the conveying platform 1. Through the above cooperation, the outer wall of the flip plate 56 can be closely fitted to the outer walls of the two ends of the pipeline by relying on the flipping process of the flip plate 56, thereby increasing the friction force when the telescopic end of the L-shaped telescopic impact plate 54 hits the pipeline, and improving the centering pushing effect of the L-shaped telescopic impact plate 54 on the pipeline. At the same time, the telescopic end of the L-shaped telescopic impact plate 54 moves synchronously with the single-sided arc plate 53, which will not hinder the traction work of the pipeline on the basis of achieving efficient centering pushing, thereby further optimizing the pipeline laying efficiency.

[0026] When in use, when the fixed end of the telescopic arc plate 46 slides toward the center of the conveyor platform 1, the fixed end of the telescopic arc plate 46 drives the sliding plate 51 to move synchronously along the conveyor platform 1, the sliding plate 51 drives the through plate 52 to move synchronously, and the through plate 52 drives the single-sided arc plate 53 to move synchronously. When the single-sided arc plate 53 moves toward the center of the buffer pad 21, it will contact the outer walls of the two ends of the pipe that are pulled down. The arc surface of the single-sided arc plate 53 contacts the outer walls of the two ends of the pipe to generate a resistance force. At this time, the single-sided arc plate 53 pushes the through plate 52 to move away from the center of the buffer pad 21. Driven by the limiting spring, the single-sided arc plates 53 on both sides move synchronously to clamp the pipeline, and at the same time, the single-sided arc plates 53 limit the pipeline away from the side of the feed platform 31. Through the above cooperation, the clamping of the single-sided arc plates 53 makes the pipeline always in a relatively central position when it falls to the top of the buffer pad 21, avoiding the pipeline from being tilted after falling, thereby increasing the difficulty of unloading and the length of laying time. At the same time, the non-arc side of the single-sided arc plate 53 limits the two ends of the pipeline to prevent the pipeline from rolling toward the feed platform 31 after falling; the sliding plate 51 moves toward the center of the buffer pad 21 When the sliding plate 51 slides, it drives the friction wheel 58 to move synchronously along the top of the conveyor platform 1, and the friction wheel 58 starts to rotate due to the friction force during the movement. When the sliding plate 51 slides, it drives the L-shaped telescopic impact plate 54 to move synchronously, and the L-shaped telescopic impact plate 54 drives the cross bar 55 to move synchronously, and the cross bar 55 drives the flip plate 56 to move synchronously, and the telescopic end of the L-shaped telescopic impact plate 54 synchronizes the vertical rod 57 with the single-sided arc plate 53 to achieve synchronous movement. When the outer wall of the top of the flip plate 56 contacts the pipeline before the telescopic end of the L-shaped telescopic impact plate 54, a resistance force will be generated, and the flip plate 56 starts to move due to the resistance force. By flipping along the outer wall of the cross bar 55, the flip plate 56 is limited by the torsion spring to generate reverse thrust for reset. Through the above cooperation, the flipping process of the flip plate 56 enables the outer wall of the flip plate 56 to fit tightly against the outer walls of both ends of the pipeline, thereby increasing the friction force when the telescopic end of the L-shaped telescopic impact plate 54 hits the pipeline, and improving the centering pushing effect of the L-shaped telescopic impact plate 54 on the pipeline. At the same time, the telescopic end of the L-shaped telescopic impact plate 54 moves synchronously with the single-sided arc plate 53, which will not hinder the traction work of the pipeline on the basis of achieving efficient centering pushing, thereby further optimizing the pipeline laying efficiency.

[0027] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an auxiliary device 6; The auxiliary device 6 includes a reciprocating screw 61, a ring slide 62 and a vibration plate 63. Both ends of the reciprocating screw 61 are fixedly mounted on the side of the friction wheel 58 close to the center of the sliding plate 51. The ring slide 62 penetrates inside and is movably mounted on the outer wall of the reciprocating screw 61. The ring slide 62 is slidably mounted on the outer wall of the sliding plate 51 close to the side of the reciprocating screw 61. The top of the vibration plate 63 is fixedly mounted on the bottom of the fixed end of the L-shaped telescopic impact plate 54, and the bottom end of the vibration plate 63 is located on the movement trajectory of the top of the ring slide 62. Through the above cooperation, the L-shaped telescopic impact plate 54 is caused to carry a slight vibration and contact with the two ends of the pipeline. Similarly, the flip plate 56 can increase the friction between itself and the two ends of the pipeline with a slight vibration, and further enhance the centering pushing effect of the L-shaped telescopic impact plate 54 on the pipeline on the original basis, so as to prevent the L-shaped telescopic impact plate 54 from misaligning due to uneven force during the process of pushing the pipeline, thereby causing the pipeline to tilt in one direction.

[0028] The auxiliary device 6 also includes a contact plate 64, an L-shaped arc panel 65, a U-shaped frame 66, a friction frame 67 and an arc block 68. The contact plate 64 is fixedly installed on the outer wall of the ring slide plate 62 near the side of the penetration plate 52, and the L-shaped arc panel 65 is slidably installed on the outer wall of the sliding plate 51 near the side of the penetration plate 52 through a spring. The outer wall of the bottom end of the U-shaped frame 66 penetrates and is hinged inside the L-shaped arc panel 65. Both ends of the friction frame 67 are hinged inside the top of the U-shaped frame 66 through a torsion spring, and the outer wall of the arc block 68 is slidably installed inside the friction frame 67 through a longitudinal spring.

[0029] The bottom of the L-shaped arc panel 65 is located on the arc motion trajectory of the top of the resistance plate 64. A torsion spring is arranged between the U-shaped frame 66 and the inside of the L-shaped arc panel 65. The top of the arc block 68 contacts the bottom of the through-plate 52. Through the above cooperation, the outer wall of the through-plate 52 is actively scraped by the friction frame 67 and the arc block 68 to ensure the cleanliness of the bottom of the through-plate 52 and avoid the through-plate 52 from reducing the sliding smoothness inside the sliding plate 51 due to dirt attached to the outer wall. When the through-plate 52 shrinks through the resistance of the pipeline, the friction frame 67 and the arc block 68 are in passive friction with the bottom of the through-plate 52, and the reciprocating movement ensures that the through-plate 52 is not disturbed during the sliding process, prevents the shrinkage from being blocked and causes the through-plate 52 to be slightly tilted, thereby reducing the centering push effect on the pipeline.

[0030] When in use, the friction wheel 58 rotates and drives the reciprocating screw 61 to rotate. When the reciprocating screw 61 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the ring slide 62, so that the ring slide 62 can slide back and forth horizontally and reset along the outer wall of the sliding plate 51. During the horizontal movement of the ring slide 62, it will contact the bottom end of the vibration plate 63 at the bottom of the fixed end of the L-shaped telescopic collision plate 54, causing the bottom end of the vibration plate 63 to deform due to the resistance force and thus bend. As the ring slide 62 continues to move, it will pass over the bottom end of the vibration plate 63 in the bent posture. At this time, the vibration plate 63 passes through During the process of self-toughness reset, it will swing back and forth to generate vibration, and the L-shaped telescopic impact plate 54 will be caused to vibrate synchronously through the transmission of force. Through the above cooperation, the L-shaped telescopic impact plate 54 will carry slight vibration and contact the two ends of the pipeline. Similarly, the flip plate 56 can increase the friction between itself and the two ends of the pipeline with slight vibration, and further improve the centering pushing effect of the L-shaped telescopic impact plate 54 on the pipeline on the original basis, so as to prevent the L-shaped telescopic impact plate 54 from misaligning due to uneven force during the process of pushing the pipeline, thereby causing the pipeline to tilt in one direction; the ring slide plate 62 slides and resets, driving the impact plate 54 to contact the two ends of the pipeline. The contact plate 64 moves synchronously. During the horizontal movement of the contact plate 64, it will contact the arc surface at the bottom end of the L-shaped arc panel 65, and push the L-shaped arc panel 65 to slide upward along the outer wall of the sliding plate 51. The L-shaped arc panel 65 drives the U-shaped frame 66 to move synchronously. When the U-shaped frame 66 moves upward, it drives the friction frame 67 to move synchronously along the bottom of the through plate 52. At this time, the hinge axis between the friction frame 67 and the U-shaped frame 66 starts to rotate, and pushes the friction frame 67 to drive the arc block 68 to slide along the L-shaped arc panel 65 away from the sliding plate 51. At the same time, the arc block 68 is limited by the spring to push itself up The part can always be in close contact with the bottom of the L-shaped arc panel 65. Through the above cooperation, the friction frame 67 and the arc block 68 are used to actively scrape the outer wall of the through-plate 52 to ensure the cleanliness of the bottom of the through-plate 52 and avoid the through-plate 52 from reducing the sliding smoothness inside the sliding plate 51 due to dirt attached to the outer wall. When the through-plate 52 shrinks through the resistance of the pipeline, the friction frame 67 and the arc block 68 passively rub against the bottom of the through-plate 52, and the reciprocating movement ensures that the through-plate 52 is not disturbed during the sliding process, prevents the shrinkage from being blocked and causes the through-plate 52 to be slightly tilted, thereby reducing the centering push effect on the pipeline.
