Description

Technical Field

[0001] The invention relates to the technical field of pipe unwinding devices, and in particular to a mobile unwinding device for subway water supply, drainage and fire protection pipes. Background Art

[0002] The pipe unwinding device is a structure for retracting and extending the pipe. During the use of the pipe, the flexible retraction and extension of the pipe facilitates the flexible use of longer pipes, and the rewinding of the pipe after use facilitates the later carrying of the pipe.

[0003] The Chinese patent with the patent number "CN208199965U" discloses a "subway water supply, drainage and fire protection pipe unwinding device", which records "a workbench, multiple groups of unwinding mechanisms, a limit assembly, a push rod mechanism and an electric control mechanism; multiple groups of unwinding mechanisms are arranged in parallel on the workbench, each group of unwinding mechanisms includes an unwinding disc, a connecting shaft, an unwinding bracket, and a rotating motor; the middle part of the outer side of the unwinding disc is connected to the output shaft of the rotating motor through a connecting shaft, and three unwinding brackets are arranged around the shaft wall of the connecting shaft. The angle between each two adjacent unwinding brackets is 120 degrees, and each unwinding bracket is provided with a clamping groove; weight-reducing holes are provided on the outer and inner sides of the unwinding disc, and the weight-reducing holes are blind holes, and the weight-reducing holes on the inner and outer sides of the unwinding disc are staggered. The utility model reasonably arranges the positions of the necessary components, thereby improving the overall space utilization, and the multiple groups of unwinding discs placed on the workbench also meet the requirements of releasing the water supply and drainage pipes at the same time."

[0004] However, this device has the following disadvantages when in use: in the actual unwinding process of the pipe, multiple pipes usually need to be reeled in simultaneously through the drive of the motor, and the pipes have different lengths. After the pipe on one reel is reeled in, continuing to drive the reeling roller to rotate can easily cause the reeled pipe to become loose.

[0005] To this end, we propose a mobile unwinding device for subway water supply, drainage and fire protection pipes. Summary of the Invention

[0006] The purpose of the present invention is to provide a mobile subway water supply, drainage and fire protection pipe unwinding device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a mobile subway water supply, drainage and fire protection pipe unwinding device, comprising a base plate, an upper surface of the base plate is provided with a squeezing mechanism, and further comprising: a winding mechanism respectively arranged on the base plate for flexibly retracting and unwinding the pipe, the winding mechanism comprising a first limit plate and a second limit plate fixedly mounted on the base plate, a rotating shaft being rotatably mounted inside the first limit plate and the second limit plate, a motor being fixedly mounted on the surface of the second limit plate, an output end of the motor and an end side of the rotating shaft being fixedly connected, and further comprising a winding roller for winding the pipe, and an auxiliary strip for flexibly controlling the rotation of the winding roller; a cleaning device respectively arranged on the base plate for cleaning particulate impurities adhered to the pipe, the cleaning device comprising two rows of hard bristles with a bent structure, the two rows of hard bristles being bent in opposite directions; a collecting device respectively arranged under the hard bristles for collecting and centrally processing the impurities after cleaning, the collecting device comprising a collecting bag with a collecting and processing function, an elastic ring being sewn with needle and thread at the port of the collecting bag.

[0008] The effects achieved by the above components are: by setting up the winding mechanism, the flexible driving and rotation control of the winding roller on the same rotating shaft is facilitated, and the loosening of the pipe on the winding roller after winding is completed during the simultaneous driving of multiple winding rollers is reduced, which improves the winding efficiency of the pipe on the winding roller to a certain extent. By setting up the cleaning device, the cleaning of particulate impurities adhering to the side wall of the pipe is facilitated, and the situation where hard particulate impurities adhere to the side wall of the pipe are directly squeezed by the extrusion mechanism is reduced, which easily causes particulate impurities to penetrate into the inside of the pipe, thereby improving the safety of the pipe winding project. By setting up the collecting device and supporting the collecting bag, the centralized processing of the collected particulate impurities using the collecting bag is facilitated, and the situation of secondary adhesion of particulate impurities to the pipe after winding is reduced.

[0009] Preferably, the winding mechanism also includes three fixed cylinders fixedly mounted on the side walls of the rotating shaft, the winding roller is sleeved on the side walls of the fixed cylinder, and several auxiliary strips are evenly fixed on the side walls of the fixed cylinder. The longitudinal section of the auxiliary strips is a right-angled trapezoid, and a guide groove is provided on the inner side of the winding roller.

[0010] The effect achieved by the above components is: the winding roller on the sliding fixed drum is adsorbed on the side close to the baffle. At this time, the motor is started and the casing drives the winding roller to rotate. The setting of the inclined structure auxiliary strip improves the efficiency of positioning the winding roller on the side close to the baffle.

[0011] Preferably, a baffle is fixedly installed on the end side of the fixed cylinder, four first magnetic blocks are evenly fixedly installed on the surface of the baffle, and four second magnetic blocks are evenly fixedly installed on the surface of the winding roller, and the first magnetic blocks and the second magnetic blocks are attracted to each other.

[0012] The effect achieved by the above components is: the winding roller will be affected by the magnetic force of the first magnetic block and the second magnetic block to move toward the direction close to the baffle, and the winding roller on the fixed cylinder will be easily twisted. When the guide groove on the inside of the winding roller is flipped to the position corresponding to the auxiliary strip, the winding roller will be affected by the magnetic force of the first magnetic block and the second magnetic block to move toward the direction close to the baffle.

[0013] Preferably, the side walls of the winding roller are evenly provided with a number of slots, and three limit cylinders are evenly fixedly installed on the upper surface of the base plate. The inner sliding connection of the limit cylinder is connected to the limit rod, and the upper ends of the three limit rods are fixedly installed with a limit strip. The surface of the limit rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the limit cylinder and the limit strip. A card block is fixedly installed on the upper side of the limit strip, and two sets of inclined surfaces are dug on the upper side of the card block.

[0014] The effect achieved by the above components is: the limit strip will be driven by the elastic force of the first spring on the limit cylinder to drive the limit strip and the clamping block to be sleeved on the inner wall of the clamping slot, which can restrain the rotation of the winding roller, thereby preventing the winding roller from continuing to rotate out and becoming loose. By setting two sets of inclined surfaces, the limiting efficiency between the clamping block, the clamping slot and the winding roller is improved.

[0015] Preferably, fixed blocks are fixedly mounted on the surfaces of the first limiting plate and the second limiting plate, and rotating blocks are rotatably mounted on the surfaces of the fixed blocks.

[0016] The effect achieved by the above components is: by rotating the rotating block on the fixed block, the rotating block will block the limit bar, thereby avoiding the limit bar from being lifted.

[0017] Preferably, the cleaning device also includes two fixed rods fixedly mounted on the side walls of the base plate, a limit frame fixedly mounted on the end sides of the two fixed rods, two groups of connecting pins in pairs fixedly mounted on the surface of the limit frame, a pressure plate fixedly mounted on the end faces of the two connecting pins, and the two rows of hard bristles are fixedly mounted on the surface of the pressure plate.

[0018] The effect achieved by the above components is: by putting the pipe on the inner side of the rectangular ring, the preliminary limiting work of the pipe can be achieved. The setting of the roller reduces the friction between the rectangular ring and the pipe, and improves the stability of the pipe operation. During the pumping of the pipe, the pipe will move relative to the two rows of hard bristles set on the pressure plate. The tip of the first row of hard bristles faces the side wall of the pipe, which can realize the cleaning of granular impurities such as stones adhering to the side wall of the pipe, and the side wall of the second row of hard bristles is used to clean the side wall of the pipe, which facilitates the stable cleaning of impurities adhering to the side wall of the pipe.

[0019] Preferably, two sliding pins are provided for sliding inside the limit frame, and an arc strip is fixedly installed on the ends of the two sliding pins that are close to each other, and a fixing plate is fixedly installed on the ends of the two sliding pins that are away from each other. Four second springs are fixedly installed on the side where the fixing plate and the limit frame are close to each other, and two plates are fixedly installed on the side wall of the limit frame, and rectangular rings are fixedly installed on the end sides of the two plates, and a number of rollers are evenly rotated and installed on the side wall of the rectangular ring.

[0020] The effect achieved by the above components is that both sliding pins will be pressed against the surface of the pipe by the elastic force of the second spring on the fixed plate, which can achieve deep scraping of impurities adhering to the side wall of the pipe, further improving the cleaning efficiency of impurities adhering to the side wall of the pipe.

[0021] Preferably, a connecting strip is fixedly installed on the surface of the pressure plate, the cross-section of the connecting strip is "U"-shaped, a scraper rod is slidably passed through the interior of the connecting strip, the cross-section of the scraper rod is diamond-shaped, a third spring is fixedly installed on the side where the scraper rod and the connecting strip are close to each other, and a steel ball is rotatably installed inside the scraper rod.

[0022] The effect achieved by the above components is: the scraper strip will be driven by the elastic force of the third spring to drive the steel ball to stick to the outside of the pipe, and the side wall of the scraper block can scrape away hard particles adhering to the side wall of the pipe, thereby improving the cleaning efficiency of impurities adhering to the side wall of the pipe. The setting of the steel ball reduces the friction between the scraper block and the pipe, thereby improving the safety of the scraper block.

[0023] Preferably, the collecting device also includes two rectangular pieces fixedly mounted on the side walls of the substrate, the side walls of the two rectangular pieces are fixedly mounted with arc frames, both sides of the arc frames are fixedly mounted with limit frames with a "U"-shaped cross section, the side walls of the two limit frames are rotatably mounted with drive plates, the upper side cross section of the drive plate is "U"-shaped, and the side walls of the arc frames are evenly fixed with several support frames.

[0024] The effect achieved by the above components is: stretch out the elastic ring, and put the collection bag with the elastic ring on the outside of the two driving plates. At this time, press the upper position to drive the driving plate, and the driving plate will drive the elastic ring to roll into the upper inner wall of the driving plate. At this time, the bag opening of the collection bag can be stretched out, and the elastic ring shrinks, which improves the stability of the bag opening of the collection bag on the outside of the arc frame. At this time, impurities will fall into the inner wall of the collection bag along the groove frame, thereby facilitating the centralized processing of impurities in the process of handling. Press the two driving plates that are raised at the lower position to quickly remove the collection bags on the two driving plates.

[0025] Preferably, two connecting ropes are fixedly mounted on the side wall of the driving plate, and gravity balls are fixedly mounted on the ends of the two connecting ropes.

[0026] The effect achieved by the above components is: the driving plate will be driven by the gravity of the gravity ball on the connecting rope to rotate on the surface of the limit frame. At this time, the two limit frames will form an inverted "eight" structure, which facilitates the efficiency of expanding the collection bag in the later stage.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention facilitates the flexible driving and rotation control of the winding roller on the same rotating shaft by setting a winding mechanism, reduces the loosening of the pipe on the winding roller after winding is completed during the simultaneous driving of multiple winding rollers, and improves the winding efficiency of the pipe on the winding roller to a certain extent.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] See also Figure 1-10The present invention provides a technical solution: a mobile subway water supply and drainage fire protection pipe unwinding device, comprising a base plate 1, an upper surface of the base plate 1 is provided with a squeezing mechanism 2, and further comprising: a reeling mechanism 3 respectively provided on the base plate 1 for flexibly retracting and unreeling the pipe, the reeling mechanism 3 comprising a first limiting plate 301 and a second limiting plate 302 fixedly mounted on the base plate 1, a rotating shaft 308 being rotatably mounted inside the first limiting plate 301 and the second limiting plate 302, a motor 303 being fixedly mounted on the surface of the second limiting plate 302, an output end of the motor 303 being fixed to an end side of the rotating shaft 308 The connection also includes a winding roller 304 for winding the pipe, and an auxiliary strip 313 for flexibly controlling the rotation of the winding roller 304; cleaning devices 4 are respectively arranged on the substrate 1 for cleaning particulate impurities adhering to the pipe, and the cleaning device 4 includes two rows of hard bristles 407 with a bent structure, and the two rows of hard bristles 407 are bent in opposite directions; collecting devices 5 are respectively arranged under the hard bristles 407 for collecting and centrally processing the impurities after cleaning, and the collecting device 5 includes a collecting bag 53 with a collecting and processing function, and an elastic ring 59 is sewn at the port of the collecting bag 53 with needle and thread. By setting up the winding mechanism 3, the flexible driving and rotation control of the winding roller 304 on the same rotating shaft 308 is facilitated, and the looseness of the pipe on the winding roller 304 after winding is completed during the simultaneous driving of multiple winding rollers 304 is reduced, which improves the winding efficiency of the pipe on the winding roller 304 to a certain extent. By setting up the cleaning device 4, the cleaning of particulate impurities adhered to the side wall of the pipe is facilitated, and the situation that hard particulate impurities adhere to the side wall of the pipe are directly squeezed by the extrusion mechanism 2 is reduced, which easily causes particulate impurities to penetrate into the inside of the pipe, thereby improving the safety of the pipe winding project. By setting up the collecting device 5 and supporting the collecting bag 53, the centralized processing of the collected particulate impurities by the collecting bag 53 is facilitated, and the situation of secondary adhesion of particulate impurities to the pipe after winding is reduced.

[0044] The following describes in detail the specific configuration and functions of the winding mechanism 3, the cleaning device 4 and the collecting device 5.

[0045] Reference Figures 1-6 As shown, in this embodiment, the winding mechanism 3 further includes three fixed cylinders 309 fixedly mounted on the side walls of the rotating shaft 308. The winding roller 304 is sleeved on the side walls of the fixed cylinders 309. A plurality of auxiliary strips 313 are evenly fixedly mounted on the side walls of the fixed cylinders 309. The longitudinal section of the auxiliary strips 313 is a right-angled trapezoid. A guide groove 318 is formed on the inner side of the winding roller 304. The winding roller 304 is slid onto the fixed cylinders 309 and is adsorbed on the side near the baffle 314. At this time, starting the motor 303 can drive the winding roller 304 to rotate. The provision of the inclined auxiliary strips 313 improves the efficiency of positioning the winding roller 304 near the baffle 314.

[0046] A baffle 314 is fixedly mounted on the end of the fixed cylinder 309. Four first magnets 315 are evenly fixedly mounted on the surface of the baffle 314. Four second magnets 316 are evenly fixedly mounted on the surface of the winding roller 304. The first magnets 315 and the second magnets 316 attract each other. The winding roller 304 is influenced by the magnetic forces of the first and second magnets 315 and 316, moving toward the baffle 314. This allows the winding roller 304 to be easily twisted on the fixed cylinder 309. When the guide groove 318 inside the winding roller 304 flips to a position corresponding to the auxiliary strip 313, the winding roller 304 is magnetically attracted to the baffle 314 by the first and second magnets 315 and 316.

[0047] The side walls of the winding roller 304 are evenly provided with a number of slots 317, and three limiting cylinders 305 are evenly fixedly installed on the upper surface of the base plate 1. The limiting cylinders 305 are internally slidably connected to the limiting rods 306, and the upper ends of the three limiting rods 306 are fixedly installed with limiting strips 310. The surface of the limiting rods 306 is covered with a first spring 307, and the two ends of the first spring 307 are respectively fixedly connected to the limiting cylinder 305 and the limiting strip 310, and a card block 319 is fixedly installed on the upper side of the limiting strip 310, and two sets of inclined surfaces are dug on the upper side of the card block 319. The limiting strip 310 is driven by the elastic force of the first spring 307 on the limiting cylinder 305 to move the limiting strip 310 and the clamping block 319 around the inner wall of the clamping slot 317, thereby restraining the rotation of the winding roller 304 and preventing the winding roller 304 from continuing to rotate and becoming loose. The provision of two sets of inclined surfaces improves the limiting efficiency between the clamping block 319, the clamping slot 317, and the winding roller 304. A fixed block 311 is fixedly mounted on the surface of each of the first limiting plate 301 and the second limiting plate 302. A rotating block 312 is rotatably mounted on the surface of the fixed block 311. Rotating the rotating block 312 on the fixed block 311 will block the limiting strip 310, preventing the limiting strip 310 from lifting.

[0048] Reference Figure 1 and Figure 2 as well as Figure 7-Figure 8As shown, the cleaning device 4 further includes two fixed rods 403 fixedly mounted on the side walls of the base plate 1. A limit frame 401 is fixedly mounted on the ends of the two fixed rods 403. Two groups of connecting pins 409, each in pairs, are fixedly mounted on the surface of the limit frame 401. A pressure plate 402 is fixedly mounted on the end faces of the two connecting pins 409. Two rows of hard bristles 407 are fixedly mounted on the surface of the pressure plate 402. The pipe is placed inside the rectangular ring 410 to achieve preliminary position limiting of the pipe. The provision of the roller 411 reduces the friction between the rectangular ring 410 and the pipe, thereby improving the stability of the pipe operation. During the pumping process of the pipe, the pipe moves relative to the two rows of hard bristles 407 provided on the pressure plate 402. The tips of the first row of hard bristles 407 face the pipe sidewall, thereby removing granular impurities such as stones adhering to the pipe sidewall. The sidewalls of the pipe sidewall are cleaned by the sidewalls of the second row of hard bristles 407, facilitating the stable cleaning of impurities adhering to the pipe sidewall.

[0049] Two sliding pins 405 are slidably mounted within the limit frame 401. A curved bar 408 is fixedly mounted on the ends of the two sliding pins 405 that are positioned closer to each other, and a fixed plate 404 is fixedly mounted on the ends of the two sliding pins 405 that are positioned farther away from each other. Four second springs 406 are fixedly mounted on the side where the fixed plate 404 and the limit frame 401 are positioned closer to each other. Two plates are fixedly mounted on the sidewalls of the limit frame 401, each of which has a rectangular ring 410 fixedly mounted on its end. Several rollers 411 are uniformly mounted on the sidewalls of the rectangular rings 410 for uniform rotation. The two sliding pins 405 are pressed against the surface of the pipe by the elastic force of the second springs 406 on the fixed plate 404, enabling deep scraping of impurities adhering to the pipe sidewalls, further improving the efficiency of cleaning impurities adhering to the pipe sidewalls. A connecting strip 415 is fixedly mounted on the surface of the pressure plate 402. The connecting strip 415 has a "U"-shaped cross section, and a scraper rod 412 is slidably inserted into the interior of the connecting strip 415. The scraper rod 412 has a diamond-shaped cross section. A third spring 414 is fixedly mounted on the side where the scraper rod 412 and the connecting strip 415 are close to each other, and a steel ball 413 is rotatably mounted inside the scraper rod 412. The elastic force of the third spring 414 drives the steel ball 413 against the outside of the pipe. The sidewall of the scraper can scrape away hard particles adhering to the pipe sidewall, improving the efficiency of cleaning impurities adhering to the pipe sidewall. The provision of the steel ball 413 reduces friction between the scraper and the pipe, improving the safety of the scraper.

[0050] Reference Figure 1 and Figure 2 as well as Figure 9-10As shown, specifically, the collecting device 5 also includes two rectangular pieces 51 fixedly mounted on the side walls of the substrate 1, and the side walls of the two rectangular pieces 51 are fixedly mounted with an arc frame 52, and both sides of the arc frame 52 are fixedly mounted with a limit frame 55 with a "U"-shaped cross section, and the side walls of the two limit frames 55 are rotatably mounted with a drive plate 56, and the upper side cross section of the drive plate 56 is "U"-shaped, and the side walls of the arc frame 52 are evenly fixedly mounted with a number of support frames 54. Stretch out the elastic ring 59 and put the collection bag 53 with the elastic ring 59 on the outside of the two driving plates 56. At this time, press the upper position to drive the driving plate 56. The driving plate 56 will drive the elastic ring 59 to roll into the upper inner wall of the driving plate 56. At this time, the bag opening of the collection bag 53 can be stretched out, and the elastic ring 59 shrinks, which improves the stability of the bag opening of the collection bag 53 on the outside of the arc frame 52. At this time, impurities will fall into the inner wall of the collection bag 53 along the groove frame, thereby facilitating the centralized processing of impurities in the process of processing. Press the two driving plates 56 that are tilted up at the lower position to quickly remove the collection bag 53 on the two driving plates 56.

[0051] Two connecting ropes 57 are fixedly mounted on the side walls of the drive plate 56. A gravity ball 58 is fixedly mounted on the end of each connecting rope 57. The gravity of the gravity balls 58 on the connecting ropes 57 drives the drive plate 56 to rotate on the surface of the limiting frame 55. At this time, the two limiting frames 55 form an inverted "eight" structure, which facilitates the efficient expansion of the collection bag 53 later.

[0052] Working principle: When the pipe needs to be reeled in, the limit strip 310 is pressed downwards. When the block 319 slides out from the inner wall of the slot 317 on the reeling roller 304, the rotating block 312 on the fixed block 311 can be rotated. The rotating block 312 will block the limit strip 310, thereby preventing the limit strip 310 from being lifted. At this time, the reeling roller 304 on the sliding fixed cylinder 309 can be subjected to the magnetic force of the first magnetic block 315 and the second magnetic block 316. The winding roller 304 on the fixed cylinder 309 is easily twisted. When the guide groove 318 on the inner side of the winding roller 304 is flipped to the position corresponding to the auxiliary strip 313, the winding roller 304 is moved towards the direction close to the baffle 314 by the magnetic force of the first magnetic block 315 and the second magnetic block 316. The winding roller 304 is adsorbed on the side close to the baffle 314. At this time, the motor 303 is started to realize the winding roller 304. 4, the setting of the auxiliary strip 313 of the inclined structure improves the efficiency of positioning the winding roller 304 on the side close to the baffle 314. After the winding roller 304 is retracted to the smooth side of the fixed cylinder 309, the rotating block 312 located on the limiting strip 310 is rotated out. The limiting strip 310 is driven by the elastic force of the first spring 307 on the limiting cylinder 305 to drive the limiting strip 310 and the clamping block 319 to be sleeved on the inner wall of the clamping groove 317, which can restrain the rotation of the winding roller 304, thereby avoiding the winding roller 304 from rotating. The winding roller 304 continues to rotate and becomes loose. By setting two sets of inclined surfaces, the limiting efficiency between the block 319, the card slot 317 and the winding roller 304 is improved. By setting the winding mechanism 3, the flexible driving and rotation control of the winding roller 304 on the same rotating shaft 308 is facilitated, and the situation of the pipe on the winding roller 304 becoming loose after winding is completed during the simultaneous driving of multiple winding rollers 304 is reduced, thereby improving the winding efficiency of the pipe on the winding roller 304 to a certain extent.

[0053] The pipe is put on the inner side of the rectangular ring 410 to achieve the initial limiting work of the pipe. The setting of the roller 411 reduces the friction between the rectangular ring 410 and the pipe, and improves the stability of the pipe operation. In the process of pumping the pipe, the pipe will move relative to the two rows of hard bristles 407 set on the pressure plate 402. The tip of the first row of hard bristles 407 faces the side wall of the pipe, which can achieve the cleaning of granular impurities such as stones adhering to the side wall of the pipe, and the side wall of the second row of hard bristles 407 is used to clean the side wall of the pipe, which facilitates the stable cleaning of impurities adhering to the side wall of the pipe. The two sliding pins 405 will be pressed against the surface of the pipe by the elastic force of the second spring 406 on the fixed plate 404, which can achieve the purpose of pipe cleaning. The deep scraping of impurities adhering to the side wall of the pipe further improves the cleaning efficiency of impurities adhering to the side wall of the pipe, and the scraping strip will be driven by the elastic force of the third spring 414 to drive the steel ball 413 to stick to the outside of the pipe, and the side wall of the scraper block can realize the scraping of hard particles adhering to the side wall of the pipe, thereby improving the cleaning efficiency of impurities adhering to the side wall of the pipe. The setting of the steel ball 413 reduces the friction between the scraper block and the pipe, and improves the safety of the scraper block. By setting the cleaning device 4, the cleaning work of the granular impurities adhering to the side wall of the pipe is facilitated, and the situation that the hard granular impurities adhering to the side wall of the pipe are directly squeezed by the extrusion mechanism 2 is reduced, which easily causes the granular impurities to penetrate into the inside of the pipe, thereby improving the safety of the pipe winding project.

[0054] The driving plate 56 will be driven by the gravity of the gravity ball 58 on the connecting rope 57 to rotate on the surface of the limit frame 55. At this time, the two limit frames 55 will form an inverted "eight" structure, which is convenient for the later opening efficiency of the collection bag 53. The elastic ring 59 is opened and the collection bag 53 with the elastic ring 59 is put on the outside of the two driving plates 56. At this time, the upper position is pressed to drive the driving plate 56. The driving plate 56 will drive the elastic ring 59 to roll into the upper inner wall of the driving plate 56. At this time, the opening of the bag mouth of the collection bag 53 can be opened. The elastic ring 59 The bag 53 is contracted to improve the stability of the bag mouth of the collecting bag 53 on the outside of the arc frame 52. At this time, the impurities will fall into the inner wall of the collecting bag 53 along the groove frame, thereby facilitating the centralized treatment of the impurities. By pressing the two driving plates 56 that are tilted at the lower side, the collecting bag 53 on the two driving plates 56 can be quickly removed. By setting the collecting device 5 and supporting the collecting bag 53, the centralized treatment of the collected particulate impurities using the collecting bag 53 is facilitated, and the situation of secondary adhesion of particulate impurities to the pipeline after winding is reduced.
