Abstract
Description
Technical Field
[0001] This utility model relates to the field of MPP cable protection pipe production technology, and in particular to an automated traction device for MPP cable protection pipes. Background Technology
[0002] MPP uses modified polypropylene as its main raw material, enabling trenchless power conduit installation in special locations such as roads, railways, buildings, and riverbeds without extensive dredging, excavation, or road surface damage. Compared to the traditional trenching method, trenchless power conduit installation is more environmentally friendly, eliminating the dust, traffic congestion, and other nuisances caused by traditional construction. This technology can also be used to lay pipelines in areas where excavation is not feasible, such as historical sites, urban areas, crop and farmland protection zones, highways, and rivers.
[0003] Existing MPP power cable protection pipe traction devices can only provide simple traction for the protection pipe. Because impurities easily adhere to the surface of the protection pipe during the production process, these impurities remain on the conveying mechanism as the protection pipe passes through it. As the impurities accumulate, they affect the subsequent traction of the protection pipe and may even cause wear. The lack of a structure to remove impurities from the surface of the protection pipe in advance makes it impractical. Furthermore, the pipe is prone to wear during the traction process. Utility Model Content

[0007] Preferably, the air outlet of the air guide ring is located on the side of the air guide ring away from the adjustment mechanism.
[0008] Preferably, the adjustment mechanism includes two servo motors, two threaded connecting seats, two lead screws, four limit rods, and upper and lower limit seats.

[0009] Preferably, the auxiliary mechanism includes a limiting sleeve, a horizontal plate, an auxiliary wheel, and a spring. The limiting sleeve is slidably connected to the outer periphery of the limiting rod in the middle. The limiting sleeve is disposed between two sets of limiting seats. One end of the horizontal plate is rotatably connected to the outer periphery of the limiting sleeve through a torsion spring. The spring is sleeved on the outer periphery of the limiting rod and is disposed between the horizontal plate and the limiting seat. The auxiliary wheel is disposed at the other end of the horizontal plate in the middle.
[0010] Preferably, the traction mechanism includes a vertical plate, pulleys, a belt, a reduction motor, and a tensioning assembly. The front and rear ends of the pulleys are rotatably connected to the left and right ends of the vertical plate. The reduction motor is installed at one end of the vertical plate, and the output end of the reduction motor passes through the vertical plate and is fixedly connected to the middle of one of the pulleys. The tensioning assembly is installed in the middle of the vertical plate, and the belt is internally disposed around the two pulleys and the tensioning assembly.
[0011] Preferably, the tensioning assembly includes a support plate, a threaded rod, an internally threaded sleeve, a servo motor, a crossbar, a side plate, an adjusting wheel, and a vertical rod. The outer periphery of the support plate is disposed in the middle of the vertical plate. The lower end of the threaded rod is rotatably connected to the upper middle part of the support plate. The servo motor is installed in the lower middle part of the support plate. The upper output end of the servo motor passes through the support plate and is fixedly connected to the lower end of the threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. Drive the air pump, filter the air through the air filter, and then deliver high-pressure air into the air guide ring through the rigid riser. Then, spray it out through the annular nozzle to clean the surface of the MPP cable protection pipe body, preventing dust and impurities from adhering to the surface of the MPP cable protection pipe body and affecting the traction effect.
[0014] 2. By using a limit rod and a limit seat in conjunction, the traction mechanism cannot rotate. This drives the second servo motor, causing the lead screw to rotate. This, in turn, moves the upper traction mechanism up and down via the threaded connection seat, thus adjusting the distance between the two traction mechanisms to accommodate different sizes of MPP cable protection pipe bodies.
[0015] 3. The upper and lower springs make the limiting sleeve located in the middle of the two traction mechanisms, so that the auxiliary wheel clamps the MPP cable protection pipe body in the middle through the torsion spring, preventing the MPP cable protection pipe body from shifting during the movement.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1-5 As shown, an automated traction device for MPP cable protection pipes includes a base plate 1, a column 2 at the bottom of the base plate 1, a cleaning mechanism 4 on one side of the upper part of the base plate 1, an adjustment mechanism 6 in the middle of the base plate 1, two traction mechanisms 5 and four auxiliary mechanisms 7 in the middle of the adjustment mechanism 6, an MPP cable protection pipe body 3 inside the cleaning mechanism 4, and the MPP cable protection pipe body 3 is located between the traction mechanism 5 and the auxiliary mechanisms 7.
[0024] The cleaning mechanism 4 includes an air pump 401, a rigid riser 402, an air guide ring 403, and an air filter. The air pump 401 is installed on the lower left side of the base plate 1. The lower end of the rigid riser 402 passes through the base plate 1 and is fixedly connected to the output end of the air pump 401. The upper end of the rigid riser 402 is fixedly connected to the lower part of the air guide ring 403. The air filter is installed at the input end of the air pump 401. The air pump 401 is driven, and the air is filtered through the air filter. Then, high-pressure air is delivered into the air guide ring 403 through the rigid riser 402 and then sprayed out through the annular nozzle, thereby cleaning the surface of the MPP cable protection pipe body 3 and preventing dust and impurities from adhering to the surface of the MPP cable protection pipe body 3 and affecting the traction effect.
[0025] The air outlet of the air guide ring 403 is located on the side of the air guide ring 403 away from the adjustment mechanism 6. The direction of the gas ejection is opposite to the direction of movement of the MPP cable protection pipe body 3, so that the cleaned part of the MPP cable protection pipe body 3 is pulled by the traction mechanism 5.
[0026] The adjusting mechanism 6 includes two servo motors 601, two threaded connecting seats 602, two lead screws 603, four limit rods 604, and two sets of upper and lower limit seats 605. The two threaded connecting seats 602 are fixedly connected to the middle of the front and rear sides of the upper traction mechanism 5 on their adjacent sides. The outer circumference of the lead screw 603 is threadedly connected to the middle of the threaded connecting seat 602. The lower end of the lead screw 603 is rotatably connected to the front and rear sides of the middle of the base plate 1. The lower end of the limit rod 604 is fixedly connected to the upper part of the base plate 1. The upper limit seat 605 is slidably connected to... The upper side of the limiting rod 604 and the lower side limiting seat 605 are fixedly connected to the lower side of the limiting rod 604. The limiting seat 605 is installed on the outside of the traction mechanism 5. The limiting rod 604 and the limiting seat 605 cooperate with each other to prevent the traction mechanism 5 from rotating. The servo motor 601 is driven to rotate the lead screw 603, which in turn drives the upper traction mechanism 5 to move up and down through the threaded connection seat 602, thereby adjusting the distance between the two traction mechanisms 5 so that it can adapt to the MPP cable protection pipe body 3 of different sizes.
[0027] The auxiliary mechanism 7 includes a limiting sleeve 701, a horizontal plate 702, an auxiliary wheel 703, and a spring 704.

One end of the horizontal plate 702 is rotatably connected to the outer periphery of the limiting sleeve 701 through a torsion spring. The spring 704 is sleeved on the outer periphery of the limiting rod 604 and is located between the horizontal plate 702 and the limiting seat 605. The auxiliary wheel 703 is located at the other end of the horizontal plate 702 in the middle. Through the two springs 704, the limiting sleeve 701 is located in the middle of the two traction mechanisms 5. Thus, the torsion spring causes the auxiliary wheel 703 to clamp the MPP cable protection pipe body 3 in the middle, preventing the MPP cable protection pipe body 3 from shifting during movement.
[0028] The traction mechanism 5 includes a vertical plate 501, pulleys 502, belt 503, a geared motor 504, and a tensioning assembly 505. The front and rear ends of the pulleys 502 are rotatably connected to the left and right ends of the vertical plate 501. The geared motor 504 is installed at one end of the vertical plate 501. The output end of the geared motor 504 passes through the vertical plate 501 and is fixedly connected to the middle of one of the pulleys 502. The tensioning assembly 505 is installed in the middle of the vertical plate 501. The belt 503 is disposed inside the two pulleys 502 and the outer periphery of the tensioning assembly 505. The geared motor 504 drives the pulley 502 connected to it to rotate, thereby causing the belt 503 to rotate through the other pulley 502, thus pulling the MPP cable protection pipe body 3 to move.
[0029] The tensioning assembly 505 includes a support plate 5051, a threaded rod 5052, an internally threaded sleeve 5053, a servo motor 5054, a crossbar 5055, a side plate 5056, an adjusting wheel 5057, and a vertical rod 5058. The support plate 5051 is located on the outer periphery of the vertical plate 5051 in the middle. The lower end of the threaded rod 5052 is rotatably connected to the upper middle part of the support plate 5051. The servo motor 5054 is installed on the lower middle part of the support plate 5051, and the upper output end of the servo motor 5054 passes through the support plate. Plate 5051 is fixedly connected to the lower end of threaded rod 5052. The middle part of internal threaded sleeve 5053 is threadedly connected to the outer periphery of threaded rod 5052. The upper end of internal threaded sleeve 5053 is fixedly connected to the middle part of crossbar 5055. The outer periphery of crossbar 5055 is fixedly connected to the middle part of side plate 5056. The middle part of adjusting wheel 5057 is rotatably connected to the left and right ends of side plate 5056. The lower end of upright rod 5058 is fixedly connected to the outside of upright plate 501. The outside of side plate 5056 is slidably connected to the outer periphery of upright rod 5058.
[0030] Working principle:
[0031] The air pump 401 is driven to filter air through an air filter. High-pressure air is then delivered into the air guide ring 403 through a rigid riser 402 and sprayed out through an annular nozzle, thereby cleaning the surface of the MPP cable protection pipe body 3 and preventing dust and impurities from adhering to the surface of the MPP cable protection pipe body 3 and affecting the traction effect. The limiting rod 604 and the limiting seat 605 cooperate with each other to prevent the traction mechanism 5 from rotating. The servo motor 601 is driven to rotate the lead screw 603, which drives the upper traction mechanism 5 to move up and down through the threaded connection seat 602, thereby adjusting the distance between the two traction mechanisms 5 to adapt to different sizes of MPP cable protection pipe bodies 3. The upper and lower springs 704 keep the limiting sleeve 701 in the middle of the two traction mechanisms 5, and the torsion spring causes the auxiliary wheel 703 to clamp the MPP cable protection pipe body 3 in the middle, preventing the MPP cable protection pipe body 3 from deviating during the movement.
