Description

Technical Field

[0001] The present invention relates to the technical field of water infiltration pipes, and particularly to a device for sleeving a cloth sleeve on a plastic water infiltration pipe and its working method. Background Art

[0002] A water infiltration pipe is a pipe specifically used for drainage and water infiltration functions, and is widely used in fields such as construction, gardening, and agriculture. Its main materials are plastics such as PE and PVC. The main function of the water infiltration pipe is to enable water to smoothly seep out from the surrounding soil and flow into the pipe at the occasion where drainage or water infiltration is required, so as to achieve the purpose of drainage.

[0003] As Figure 1 shown, in order to filter sediment, it is often necessary to wrap a geotextile sleeve 21 on the outer side of the plastic water infiltration pipe. At present, the geotextile sleeve 21 is often manually sleeved on the plastic water infiltration pipe on a platform. The length specifications of the plastic water infiltration pipe are generally 4 meters or 6 meters. Even for an ordinary round pipe, the process of sleeving the geotextile sleeve 21 is rather laborious. Especially when using a plastic corrugated pipe 20, this kind of plastic pipe with corrugated rings has a large resistance on the outer wall and is even more difficult to sleeve the geotextile sleeve 21. Two skilled workers can at most sleeve 300 4-meter plastic corrugated pipes 20 per day. This sleeving process is a production bottleneck of such products. Currently, it severely restricts the production efficiency of the water infiltration pipe.

[0004] In order to overcome the above problems, a device for sleeving a cloth sleeve on a plastic water infiltration pipe and its working method are needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for sleeving a cloth sleeve on a plastic water infiltration pipe and its working method, which mechanizes the sleeving of the geotextile sleeve onto the plastic corrugated pipe, greatly improves the production efficiency, and reduces the labor intensity of workers.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A device for sleeving a cloth sleeve on a plastic water infiltration pipe of the present invention includes:

[0008] A frame, which is welded into a rectangular parallelepiped-shaped frame structure by using steel profiles. Side wall plates are symmetrically welded inside the two vertical arms, and linear guide rails are horizontally installed on the side wall plates;

[0009] A cantilever pipe, whose root is fixedly connected to one end of the frame. The cantilever pipe is parallel to the linear guide rail and is centrally arranged between the two side wall plates. The plastic corrugated pipe that needs to be sleeved with the geotextile sleeve can be sleeved on the cantilever end of the cantilever pipe;

[0010] The cloth sleeve fixture is connected to the linear guide rail in a guiding and sliding manner. A round tube sleeve is arranged in the middle of the cloth sleeve fixture. The round tube sleeve is coaxially arranged with the cantilever tube and the inner diameter is larger than the outer diameter of the plastic corrugated tube. The end of the geotextile sleeve is folded and pressed against the round tube sleeve.

[0011] Furthermore, the cloth sleeve fixture also includes a clamping assembly, a slide plate and a slider. The outer periphery of the circular tube sleeve is connected to the slide plate through a vertical plate, and the slide plate is connected to the linear guide rail through the slider. Two sets of the clamping assemblies are symmetrically arranged on the outside of the circular tube sleeve. The clamping assembly is installed on the vertical plate and the clamping assembly is facing the working end of the circular tube sleeve to press the end of the geotextile sleeve folded on the circular tube sleeve.

[0012] Furthermore, the clamping assembly includes a cylinder support, a clamping cylinder and a clamping half ring. The front end flange of the clamping cylinder is installed on the vertical plate through the cylinder support. The piston rod end of the clamping cylinder is installed with the clamping half ring. The clamping half ring can press the end of the geotextile sleeve onto the outer wall of the circular tube sleeve.

[0013] Furthermore, it also includes a driving component, which is arranged on the frame and below the cantilever tube, and the driving component drives the cloth cover fixture to slide back and forth along the linear guide rail.

[0014] Furthermore, the driving assembly includes a reduction motor, a driving sprocket, a driven sprocket and a chain. The reduction motor is installed below the root of the cantilever tube through a vertical plate seat, the driving sprocket is installed on the reduction motor output shaft, and the driven sprocket is supported below the cantilever end of the cantilever tube through a sprocket support. The chain transmission connects the driving sprocket and the driven sprocket, and the upper and lower sections of the chain are parallel to the linear guide rail; a chain clamp is provided at the bottom of the vertical plate, and the chain clamp is connected to a link of the upper section of the chain.

[0015] Furthermore, it also includes a guide cap, which is in the form of a cone cap and is threadedly connected to the cantilever end of the cantilever tube.

[0016] Furthermore, it also includes an air blowing component, which blows compressed air into the cantilever tube; a plurality of air outlet holes are opened on the outer wall of the cantilever tube.

[0017] Furthermore, a plurality of grooves are evenly distributed on the circumference of the outer wall of the cantilever tube, and a plurality of the air outlet holes are arranged at equal intervals along the grooves; the positions of the grooves correspond to the water-permeable holes on the plastic corrugated tube.

[0018] Further, the air-blowing assembly includes a piston member, a pull rope, an air pipe, and a compression spring. The piston member is slidably guided in the inner hole of the cantilever pipe. The inner ends of the pull rope and the air pipe are both connected to the piston member. The air pipe blows compressed air into the cavity between the piston member and the guide cap through the air jet joint on the piston member. The compression spring is coaxially arranged in the inner hole of the cantilever pipe, and both ends of the compression spring respectively abut between the rear end wall of the cantilever pipe and the piston member. The outer end of the air pipe is connected to an air source, and the pull rope is connected to a traction mechanism.

[0019] The present invention also discloses a working method for a plastic water-permeable pipe sleeve cloth sleeve device, which uses the plastic water-permeable pipe sleeve cloth sleeve device described in any one of the above to perform the operation of sleeving a geotextile sleeve on a plastic corrugated pipe.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are:

[0021] For the plastic water-permeable pipe sleeve cloth sleeve device of the present invention, by sleeving the plastic corrugated pipe on the cantilever end of the cantilever pipe for fixation, the plastic corrugated pipe is suspended all around, and the geotextile sleeve can be sleeved without flipping. By driving the open end of the geotextile sleeve to slide along the linear guide rail with the cloth sleeve fixture, the geotextile sleeve can be completely sleeved on the plastic corrugated pipe throughout its length. The plastic water-permeable pipe sleeve cloth sleeve device of the present invention mechanizes the sleeving of the geotextile sleeve on the plastic corrugated pipe, greatly improving the production efficiency and reducing the labor intensity of workers.

[0022] In addition, slide plates are respectively arranged at both ends of the cloth sleeve fixture. Each slide plate is slidably connected to a linear guide through four sliders, enabling the cloth sleeve fixture to reciprocate smoothly along the axial direction of the cantilever pipe, ensuring the uniformity of the spacing gap between the outer wall of the circular pipe sleeve and the plastic corrugated pipe over the entire circumference. The clamping cylinder is used to push and pull the half-ring clamp to press the end of the geotextile sleeve onto the outer wall of the circular pipe sleeve or release it, achieving rapid clamping. Rubber pads and pointed protrusion structures are added to the opposite surfaces of the circular pipe sleeve and the half-ring clamp to prevent the geotextile sleeve from falling off during dragging. By adding the drive assembly below the cantilever pipe to replace manual driving of the cloth sleeve fixture, the labor intensity of workers is reduced. By adopting a chain and sprocket drive method for the cloth sleeve fixture, the structure is compact, the equipment cost is low, and it is also easy to implement. By adding a guide cap in the form of a cone cap to the cantilever end of the cantilever pipe, the geotextile sleeve being conveyed backward is continuously pushed open in the center, facilitating sleeving. By adding a sealing ring, on the one hand, it can form a seal for the radial gap at the end of the plastic corrugated pipe, and on the other hand, it can also fix the plastic corrugated pipe circumferentially and axially using the tensioning effect of the sealing ring to prevent the plastic corrugated pipe from rotating or moving during the process of sleeving the geotextile sleeve. By adding the air-blowing assembly to the fixed end of the cantilever pipe, during the movement of the cloth sleeve fixture, the air-blowing assembly blows compressed air into the cantilever pipe. The dissipated compressed air blows the geotextile sleeve into a circular shape, ensuring that the geotextile sleeve and the outer wall of the plastic corrugated pipe are separated by the dissipated compressed air. The pneumatic friction resistance is much smaller than the friction resistance of direct contact, ensuring the rapid sleeving of the geotextile sleeve. By making the position of the groove correspond to the position of the water-permeable hole on the plastic corrugated pipe, it is ensured that the air discharged from the air outlet can smoothly escape through the water-permeable hole, reducing the air outlet resistance. By adding a sliding piston part that can be guided in the middle hole of the cantilever pipe, when starting the sleeving operation, only compressed air needs to be blown from the cantilever end of the cantilever pipe, avoiding waste and reducing the consumption of compressed air. Through the setting of the pull rope and the compression spring, the traction mechanism can pull the pull rope to move the piston part backward, increasing the air outlet length on the cantilever pipe. The compression spring can reset the piston part, facilitating the next sleeving operation. By adding a fixed pulley to deflect the pull rope and directly installing it on the chain, one set of drive can simultaneously drive the piston part and the cloth sleeve fixture, and at the same time ensure their synchronous movement, achieving a good effect of blowing and sleeving. By adding an air pipe reel, the loose air pipe can be promptly wound up and concentrated, eliminating the need for manual winding and avoiding the air pipe from winding around the pull rope, making the equipment operation more stable and reliable.

[0023] The working method of the plastic water-permeable pipe sleeve cloth sleeve device of the present invention is that the cantilever pipe of the cantilever type holds the plastic corrugated pipe, without obstruction, facilitating the sleeving of the geotextile sleeve. By using the method of blowing compressed air to isolate the plastic corrugated pipe and the geotextile sleeve and then sleeving, the contact resistance is reduced, enabling the sleeving operation to proceed smoothly.

[0033] The core of the present invention is to provide a cloth sleeve device for plastic water seepage pipe and its working method, which mechanizes the sleeving of geotextile sleeve onto the plastic corrugated pipe, greatly improving the production efficiency and reducing the labor intensity of workers.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] Referring to the accompanying drawings, Figure 1 is a schematic diagram of the existing plastic water infiltration pipe sleeve cloth sleeve; Figure 2 is a schematic diagram of the main sectional structure of the plastic water infiltration pipe sleeve cloth sleeve device of the present invention; Figure 3 is a schematic diagram of the top view structure of the plastic water infiltration pipe sleeve cloth sleeve device of the present invention; Figure 4 is a schematic diagram of the main view structure of the cloth sleeve fixture in the present invention; Figure 5 is Figure 4 a schematic diagram of the upward view structure; Figure 6 is a schematic diagram of the main sectional structure of the cantilever pipe in the present invention; Figure 7 is Figure 6 a partial enlarged structure diagram of the installation position of the guide cap in

[0037] In a specific embodiment, as Figures 1 - 7 shown, the plastic water infiltration pipe sleeve cloth sleeve device of the present invention includes:

[0038] A frame 1, which is welded into a rectangular parallelepiped-shaped frame structure using profiled steel square pipes, and vertical arms are provided on both sides of the top opening. Side wall plates 101 are symmetrically welded inside the two vertical arms. The side wall plates 101 are vertically arranged, and linear guide rails 102 are horizontally installed on the inner side walls of the side wall plates 101. Two linear guide rails 102 are arranged in parallel on each side wall plate 101.

[0039] The cantilever pipe 2 is a circular pipe and its root is fixedly connected to one end of the frame 1. A support auxiliary frame is provided at one end of the frame 1. The support auxiliary frame includes two layers of horizontally arranged square pipe crossbeams. The root of the cantilever pipe 2 is fixedly inserted between the two layers of square pipe crossbeams and is welded to the support auxiliary frame through a rear flange plate 203 and a front flange plate 204. In order to offset the sag of the cantilever end of the cantilever pipe 2, angle stiffeners are welded between the root of the cantilever pipe 2 and the support auxiliary frame. The cantilever pipe 2 is parallel to the linear guide rail 102 and is centrally arranged between two side wall plates 101. The plastic corrugated pipe 20 that needs to be sleeved with the geotextile sleeve 21 can be fitted and sleeved on the cantilever end of the cantilever pipe 2. That is to say, the bottom diameter of the plastic corrugated pipe 20 is adapted to the outer diameter of the cantilever pipe 2.

[0040] The cloth sleeve fixture 4 is guided and slidably connected to the linear guide rail 102. A circular pipe sleeve 401 is provided in the middle of the cloth sleeve fixture 4. The circular pipe sleeve 401 is coaxially arranged with the cantilever pipe 2 and its inner diameter is larger than the outer diameter of the plastic corrugated pipe 20. The open end of the geotextile sleeve 21 is turned over and pressed against the circular pipe sleeve 401.

[0041] By fixing the plastic corrugated pipe 20 by sleeving it on the cantilever end of the cantilever pipe 2, the plastic corrugated pipe 20 is suspended all around, and the geotextile sleeve 21 can be sleeved without flipping; by driving the open end of the geotextile sleeve 21 to slide along the linear guide rail 102 through the cloth sleeve fixture 4, the geotextile sleeve 21 can be completely sleeved on the plastic corrugated pipe 20 throughout its length. The plastic water seepage pipe sleeve cloth sleeve device of the present invention mechanizes the sleeving of the geotextile sleeve onto the plastic corrugated pipe, greatly improving the production efficiency and reducing the labor intensity of workers.

[0042] In a specific embodiment of the present invention, as Figures 2 - 5 shown, the cloth sleeve fixture 4 further includes a clamping assembly, a slide plate 405 and a slider 406. Vertical plates are welded around the circular pipe sleeve 401, and circular holes with the same diameter are opened in the inner circle of the circular pipe sleeve 401. The two ends of the vertical plates are welded to the slide plate 405. The slide plate 405 is connected to the linear guide rail 102 through the slider 406. Each slide plate 405 is equipped with four sliders 406, and two sliders 406 are guided and slid on one linear guide rail 102. Two sets of the clamping assemblies are symmetrically arranged outside the circular pipe sleeve 401. The clamping assemblies are installed on the vertical plates and the working ends of the clamping assemblies facing the circular pipe sleeve 401 can press the end of the geotextile sleeve 21 folded on the circular pipe sleeve 401.

[0043] Specifically, as Figure 4 and Figure 5As shown, the clamping assembly includes a cylinder support 402, a clamping cylinder 403, and a clamping semi-ring 404. The front flange of the clamping cylinder 403 is installed on the vertical plate through the cylinder support 402. The end of the piston rod of the clamping cylinder 403 is installed with the clamping semi-ring 404, and the clamping semi-ring 404 can press the end of the geotextile sleeve 21 against the outer wall of the round pipe sleeve 401.

[0044] Specifically, an anti-slip rubber pad is compounded on the outer wall of the round pipe sleeve 401, and a multi-point pointed structure is provided on the inner wall of the clamping semi-ring 404. When the clamping semi-ring 404 presses the end of the geotextile sleeve 21, it can firmly fix the end of the geotextile sleeve 21 to prevent it from falling off during the dragging process.

[0045] Obviously, the clamping assembly can also be replaced with a quick clamp or a binding rope. By using a clamp pressed by multiple circumferentially evenly distributed toggling rear struts, the end of the geotextile sleeve 21 can also be multi-point pressed against the outer wall of the round pipe sleeve 401. Using a binding rope to directly tie the end of the geotextile sleeve 21 to the outer wall of the round pipe sleeve 401 can also play a role in temporary fixation. Similar simple replacement methods all fall within the protection scope of the present invention.

[0046] By respectively arranging sliding plates 405 at both ends of the cloth sleeve clamp 4, each sliding plate 405 is slidably connected with the linear guide rail 102 through four sliders 406. The cloth sleeve clamp 4 can move smoothly back and forth along the axial direction of the cantilever pipe 2, ensuring the uniformity of the spacing gap between the outer walls of the round pipe sleeve 401 and the plastic corrugated pipe 20 within the entire circumferential range; by pushing and pulling the clamping semi-ring 404 through the clamping cylinder 403, the end of the geotextile sleeve 21 is pressed against the outer wall of the round pipe sleeve 401 or released, realizing rapid clamping. By adding a rubber pad and a pointed structure on the opposite surfaces of the round pipe sleeve 401 and the clamping semi-ring 404, it is prevented that the fixed geotextile sleeve 21 falls off during the dragging process.

[0047] In a specific embodiment of the present invention, as Figure 2 and Figure 3 shown, the plastic drainage pipe sleeve cloth sleeve device of the present invention further includes a driving assembly. The driving assembly is arranged on the frame 1 and is located below the cantilever pipe 2, and the driving assembly drives the cloth sleeve clamp 4 to slide back and forth along the linear guide rail 102.

[0048] Specifically, as Figure 2 and Figure 3As shown, the drive assembly includes a reduction motor 5, a driving sprocket 6, a driven sprocket 7, and a chain 8. The reduction motor 5 is installed below the root of the cantilever tube 2 through a vertical plate seat, and the reduction motor 5 is electrically connected to the electric control box of the equipment. The driving sprocket 6 is installed on the output shaft of the reduction motor 5, and the driven sprocket 7 is supported below the cantilever end of the cantilever tube 2 through a sprocket support. The chain 8 is drivingly connected to the driving sprocket 6 and the driven sprocket 7, and the upper and lower sections of the chain 8 are both parallel to the linear guide 102. A chain chuck 407 is provided at the bottom of the vertical plate of the cloth sleeve fixture 4, and the chain chuck 407 is directly welded to a link of the upper section of the chain 8.

[0049] Obviously, the drive assembly can also be replaced by a hydraulic cylinder with a long stroke. However, the cost of a long-stroke hydraulic cylinder is relatively high. Similar simple replacement methods all fall within the protection scope of the present invention.

[0050] By adding the drive assembly below the cantilever tube 2 to replace the manual drive of the cloth sleeve fixture 4, the labor intensity of workers is reduced; by adopting the chain and sprocket method to drive the cloth sleeve fixture 4, the structure is compact, the equipment cost is low, and it is also easy to implement.

[0051] In a specific embodiment of the present invention, as Figure 6 and Figure 7 shown, the plastic permeable water pipe cloth sleeve device of the present invention further includes a guide cap 3. The guide cap 3 is in the form of a conical cap, and the guide cap 3 is threadedly connected to the cantilever end of the cantilever tube 2. The guide cap 3 can be made of metal or plastic, and a wrench hole is provided on the outer wall of the guide cap 3.

[0052] Specifically, as Figure 7 shown, a sealing ring 301 is also sleeved on the root of the threaded section of the guide cap 3. During operation, the sealing ring 301 is pressed against the end face of the cantilever tube 2 by the rear step of the guide cap 3. The sealing ring 301 bulges outwards, and the outer wall of the sealing ring 301 contacts the inner wall of the bottom of the corrugation of the plastic corrugated pipe 20 to form an end seal.

[0053] By adding a conical cap-shaped guide cap 3 to the cantilever end of the cantilever tube 2, the geotextile sleeve 21 conveyed backward is continuously centered and pushed open, facilitating the threading; by adding the sealing ring 301, on the one hand, it can form a seal for the radial gap at the end of the plastic corrugated pipe 20, and on the other hand, it can also use the tensioning effect of the sealing ring 301 to circumferentially and axially fix the plastic corrugated pipe 20 to prevent the plastic corrugated pipe 20 from rotating or moving during the process of threading the geotextile sleeve 21.

[0054] In a specific embodiment of the present invention, as Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown in the figure, the plastic permeable pipe sleeve device of the present invention further includes a gas blowing component, which is arranged at the fixed end of the cantilever pipe 2, and the gas blowing component blows compressed air into the cantilever pipe 2. A plurality of air outlet holes 201 are formed on the outer wall of the cantilever pipe 2. The air blown out from the air outlet holes 201 escapes outward through the water permeable holes 2001 on the plastic corrugated pipe 20, and the escaped compressed air blows the geotextile sleeve 21 into a circular shape.

[0055] Specifically, as Figure 2 and Figure 3 shown, a plurality of strip grooves 202 are evenly distributed in the circumferential direction on the outer wall of the cantilever pipe 2, and a plurality of air outlet holes 201 are arranged at equal intervals along the strip grooves 202. When installing the plastic corrugated pipe 20, pay attention to the position of the strip grooves 202 corresponding to the water permeable holes 2001 on the plastic corrugated pipe 20.

[0056] By adding the gas blowing component at the fixed end of the cantilever pipe 2, during the movement of the sleeve fixture 4, the gas blowing component blows compressed air into the cantilever pipe 2, and the escaped compressed air blows the geotextile sleeve 21 into a circular shape, ensuring that the geotextile sleeve 21 and the outer wall of the plastic corrugated pipe 20 are separated by the escaped compressed air. The pneumatic frictional resistance is much smaller than the frictional resistance of direct contact, ensuring the rapid sleeving of the geotextile sleeve 21. By setting the position of the groove 202 corresponding to the position of the water permeable hole 2001 on the plastic corrugated pipe 20, it is ensured that the air blown out from the air outlet hole 201 escapes smoothly through the water permeable hole 2001 outward, reducing the air outlet resistance.

[0057] Specifically, as Figure 2 、 Figure 3 、 Figure 6 and Figure 7 shown, the gas blowing component includes a piston member 9, a pull rope 10, an air pipe 12 and a compression spring 14. The piston member 9 is slidably guided in the middle hole of the cantilever pipe 2, and the outer wall of the piston member 9 contacts the hole wall of the cantilever pipe 2 through a whole - circle feather layer 903. The use of the feather layer 903 is similar to an old - fashioned hand - operated bellows. On the one hand, it can effectively seal, and on the other hand, the frictional resistance is small, which is convenient for sliding. The inner ends of the pull rope 10 and the air pipe 12 are both connected to the piston member 9, and the air pipe 12 blows compressed air into the cavity between the piston member 9 and the guide cap 3 through the air jet joint 902 on the piston member 9. The compression spring 14 is coaxially arranged in the middle hole of the cantilever pipe 2, and the two ends of the compression spring 14 respectively abut between the rear end wall of the cantilever pipe 2 and the piston member 9, and the compression spring 14 resets the piston member 9 forward. The outer end of the air pipe 12 is connected to a source of dry and clean compressed air, and the pull rope 10 is connected to a traction mechanism.

[0058] By adding a component that can guide the sliding piston member 9 inside the hole of the cantilever tube 2, when starting the sleeving operation, it only requires blowing compressed air from the cantilever end of the cantilever tube 2, thus avoiding waste and reducing the consumption of compressed air. Through the arrangement of the pull rope 10 and the compression spring 14, the traction mechanism can pull the pull rope 10 to move the piston member 9 backward, increasing the air outlet length on the cantilever tube 2; the compression spring 14 can reset the piston member 9, facilitating the next sleeving operation.

[0059] Specifically, as Figure 2 shown, the traction mechanism includes a fixed pulley 11. The fixed pulley 11 is installed behind the root of the cantilever tube 2 through a support plate. The pull rope 10 passes around the fixed pulley 11 and is installed on a link of the lower chain 8 through a rope chuck 801.

[0060] By adding the fixed pulley 11 to redirect the pull rope 10 and directly installing it on the chain 8, a set of drive can simultaneously drive the piston member 9 and the cloth sleeve fixture 4, and also ensure their synchronous movement, resulting in a good air-blowing sleeving effect.

[0061] Specifically, as Figure 2 shown, the air-blowing assembly further includes an air pipe reel 13. The air pipe reel 13 is installed above and behind the fixed pulley 11 through the rear top plate 103 at the top. The front end of the rear top plate 103 is welded to the middle position at the top of the support auxiliary frame; the air pipe reel 13 winds and unwinds the air pipe 12. The rotating shaft of the air pipe reel 13 is a perforated rotating shaft and is connected to the output pipeline of the air source through a rotary joint 1301 at the protruding end of the rotating shaft.

[0062] Specifically, the air pipe reel 13 can be an electric reel or a reel driven by a spring, which can timely wind and collect the loosened air pipe 12 to avoid entanglement with the pull rope 10.

[0063] By adding the air pipe reel 13, the loosened air pipe 12 can be timely wound and collected, eliminating the need for manual winding and avoiding the air pipe 12 from being entangled with the pull rope 10, making the equipment operation more stable and reliable.

[0064] Working principle of the cloth sleeve device for the plastic permeable water pipe of the present invention: Insert the plastic corrugated pipe 20 to which the cloth sleeve needs to be sleeved into the cantilever end of the cantilever pipe 2. Note that the end positions of the plastic corrugated pipe 20 and the cantilever pipe 2 are approximately aligned, and the position of the groove 202 is also approximately aligned with the position of the water permeable holes 2001 on the plastic corrugated pipe 20. Install the guiding cap 3. The guiding cap 3 is screwed onto the internal threaded end of the cantilever pipe 2. The rear step of the guiding cap 3 presses the sealing ring 301 against the end face of the cantilever pipe 2. The outer wall of the tightened sealing ring 301 contacts the inner wall of the corrugated bottom of the plastic corrugated pipe 20 to form end sealing and at the same time slightly circumferentially and axially fix the plastic corrugated pipe 20. Operate the operation panel of the equipment electric control box, start the reduction motor 5, the driving sprocket 6 drives the chain 8, and then drives the cloth sleeve fixture 4 to reset to the end position of the cantilever pipe 2 along the linear guide rail 102 and stop. The operator manually leads out the end of the whole roll of geotextile sleeve 21, passes it through the guiding cap 3 and the inner hole of the round pipe sleeve 401, and manually folds the opening of the end of the geotextile sleeve 21 so that the folded edge is flipped onto the outer wall of the round pipe sleeve 401. Operate the operation panel of the equipment electric control box, the clamping cylinder 403 extends, and the clamping half ring 404 presses the folded edge of the end of the geotextile sleeve 21 against the outer wall of the round pipe sleeve 401 to form clamping and fixing. Operate the operation panel of the equipment electric control box, start the reduction motor 5, the driving sprocket 6 drives the chain 8, and then drives the cloth sleeve fixture 4 to slowly move backward along the linear guide rail 102. At the same time, the control valve of the compressed air source is opened, and dry and clean compressed air is blown into the cavity between the piston part 9 and the guiding cap 3 through the air pipe 12 and the air jet pipe joint 902. The air discharged from the air outlet 201 escapes outward through the water permeable holes 2001 on the plastic corrugated pipe 20, and the escaping compressed air blows the geotextile sleeve 21 into a circular shape. The geotextile sleeve 21 and the outer wall of the plastic corrugated pipe 20 are separated by the escaping compressed air, reducing the frictional resistance at the cloth sleeve fixture 4 part and the part of the geotextile sleeve 21 that has been sleeved, so that the cloth sleeve fixture 4 can quickly sleeve the geotextile sleeve 21 without much effort. At the same time, the rope chuck 801 of the lower section of the chain 8 pulls the pull rope 10, and the pull rope 10 pulls the piston part 9 backward, continuously expanding the length of the blowing cavity, and the flow valve on the corresponding compressed air supply pipeline is gradually opened to ensure sufficient air volume. When the cloth sleeve fixture 4 moves to the other end of the plastic corrugated pipe 20, close the control valve on the compressed air pipeline to stop the air supply; Operate the operation panel of the equipment electric control box, the clamping cylinder 403 retracts, the clamping half ring 404 releases the end of the geotextile sleeve 21, and manually flip it off the round pipe sleeve 401. Cut the geotextile sleeve 21 at one end of the guiding cap 3, use a hook wrench to disassemble the guiding cap 3, and pull the plastic corrugated pipe 20 together with the sleeved geotextile sleeve 21 off the cantilever pipe 2 and centrally place it in the finished product area. Load the next plastic corrugated pipe 20 again and repeat the above steps.

[0065] In summary, for the plastic permeable pipe sleeve device of the present invention, the plastic corrugated pipe 20 is fixed by sleeving it on the cantilever end of the cantilever pipe 2, so that the plastic corrugated pipe 20 is suspended all around, and the geotextile sleeve 21 can be sleeved without flipping; the open end of the geotextile sleeve 21 is driven by the sleeve fixture 4 to slide along the linear guide rail 102, so as to realize that the geotextile sleeve 21 is completely sleeved on the plastic corrugated pipe 20 throughout the length. The plastic permeable pipe sleeve device of the present invention mechanizes the sleeving of the geotextile sleeve onto the plastic corrugated pipe, greatly improving the production efficiency and reducing the labor intensity of workers. In addition, by respectively arranging sliding plates 405 at both ends of the sleeve fixture 4, each sliding plate 405 is slidably connected to the linear guide rail 102 through four sliders 406, and the sleeve fixture 4 can move smoothly back and forth along the axial direction of the cantilever pipe 2, ensuring the uniformity of the spacing gap between the outer wall of the circular pipe sleeve 401 and the plastic corrugated pipe 20 within the entire circumferential range; by pushing and pulling the clamping semi-ring 404 with the clamping air cylinder 403, the end of the geotextile sleeve 21 is pressed onto the outer wall of the circular pipe sleeve 401 or released, realizing quick clamping. Rubber pads and pointed protrusion structures are added on the opposite surfaces of the circular pipe sleeve 401 and the clamping semi-ring 404 to prevent the geotextile sleeve 21 from falling off during dragging. By adding the driving component below the cantilever pipe 2 to replace manual driving of the sleeve fixture 4, the labor intensity of workers is reduced; by adopting the chain and sprocket method to drive the sleeve fixture 4, the structure is compact, the equipment cost is low, and it is also easy to implement. By adding a guiding cap 3 in the form of a cone cap at the cantilever end of the cantilever pipe 2, the geotextile sleeve 21 conveyed backward is continuously centered and pushed open, facilitating the sleeving; by adding a sealing ring 301, on the one hand, it can form a seal for the radial gap at the end of the plastic corrugated pipe 20, and on the other hand, it can also axially and circumferentially fix the plastic corrugated pipe 20 by the tightening effect of the sealing ring 301 to prevent the plastic corrugated pipe 20 from rotating or moving during the sleeving of the geotextile sleeve 21. By adding the air-blowing component at the fixed end of the cantilever pipe 2, during the movement of the sleeve fixture 4, the air-blowing component blows compressed air into the cantilever pipe 2, and the dissipated compressed air blows the geotextile sleeve 21 into a circular shape, ensuring that the geotextile sleeve 21 and the outer wall of the plastic corrugated pipe 20 are separated by the dissipated compressed air, and the pneumatic friction resistance is much smaller than the friction resistance of direct contact, ensuring the quick sleeving of the geotextile sleeve 21. By setting the position of the groove 202 corresponding to the position of the water-permeable holes 2001 on the plastic corrugated pipe 20, it is ensured that the air outlet of the air outlet hole 201 can smoothly escape through the water-permeable holes 2001, reducing the air outlet resistance. By adding a guiding sliding piston part 9 that can be guided in the middle hole of the cantilever pipe 2, when starting the sleeving work, only the compressed air needs to be blown out at the cantilever end of the cantilever pipe 2, avoiding waste and reducing the consumption of compressed air. Through the setting of the pull rope 10 and the compression spring 14, the traction mechanism can pull the pull rope 10 to move the piston part 9 backward, increasing the air outlet length on the cantilever pipe 2; the compression spring 14 can reset the piston part 9, facilitating the next sleeving.By adding a fixed pulley 11 to deflect the pulling rope 10 and directly installing it on the chain 8, a set of driving mechanisms can drive the piston member 9 and the cloth sleeve fixture 4 simultaneously, ensuring their synchronous movement and achieving a good effect of blowing and sleeving. By adding an air pipe reel 13, the loose air pipe 12 can be promptly wound up and collected, eliminating the need for manual winding and preventing the air pipe 12 from winding around the pulling rope 10, making the equipment operation more stable and reliable.

[0066] The present invention also discloses a working method for a plastic infiltration water pipe cloth sleeve device, which uses the plastic infiltration water pipe cloth sleeve device in any of the above embodiments to perform the operation of sleeving the geotextile sleeve 21 on the plastic corrugated pipe 20.

[0067] The cantilevered cantilever pipe 2 holds the plastic corrugated pipe 20 without obstruction for 360 degrees, facilitating the sleeving of the geotextile sleeve 21. By using the method of blowing compressed air to isolate the plastic corrugated pipe 20 and the geotextile sleeve 21 before sleeving, the contact resistance is reduced, enabling the sleeving work to proceed smoothly.
