[0001] This invention belongs to the field of water supply and drainage engineering technology, and in particular relates to a corrugated pipe traction connection hot melt device and its usage method. Background Technology
[0002] Currently, corrugated pipes are connected by manual installation by construction workers. During installation, workers need to apply heat-shrink tape to the corrugated pipes, then manually push the two sections of corrugated pipes to pull and align them. After alignment, a blowtorch is used to heat-seal the heat-shrink tape. This construction method is time-consuming, labor-intensive, and inefficient. Summary of the Invention
[0003] The main objective of this invention is to provide a corrugated pipe traction connection hot-melt device and its usage method, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A corrugated pipe traction connection hot-melt device, comprising:
[0006] The large and small hot-melt heating coils, made of elastic material, can be electrically heated and are used to tighten the connection between two sections of corrugated pipe.
[0007] Heat shrink tape is clamped and placed between the small heat-melting heating coil and the corresponding corrugated tube, and extends out of the corrugated tube;
[0008] At least one traction device is used to pull the large and small hot melt heating coils closer together, the traction device comprising:
[0009] The first support is fixed on the large hot melt heating coil;
[0010] The second support is fixed on the small hot melt heating coil;
[0011] A hollow threaded cylinder passes through the first support base and the second support base, is fixedly connected to the first support base, and is slidably connected to the second support base;
[0012] A threaded rotating shaft is located inside the hollow threaded cylinder and is threadedly connected to the hollow threaded cylinder;
[0013] One end of the traction rope is fixedly connected to the second support base, and the other end is fixedly connected to the threaded rotating shaft.
[0014] Preferably, the large and small hot melt heating coils have a snap-fit structure.
[0015] Preferably, the buckle structure has an inwardly facing eagle beak buckle at one end of its interface, and a plurality of buckle interfaces on the outer wall of the other end that cooperate with the eagle beak buckle.
[0016] Preferably, there are two traction devices arranged symmetrically.
[0017] Preferably, the outer surfaces of the large and small hot melt heating coils are provided with a heat insulation layer.
[0018] Preferably, the insulation layer is a mica insulation board.
[0019] Preferably, the large and small hot melt heating coils are provided with power interfaces for connecting to an external power source.
[0020] Preferably, the end of the threaded rotating shaft away from the second support has a rotating handle extending out of the hollow threaded cylinder.
[0021] Preferably, the traction rope is fixedly connected to the rotating handle or fixedly connected to the threaded rotating shaft by opening a hole in the hollow threaded cylinder.
[0022] A method for using a corrugated pipe traction connection hot-melt device includes the following steps:
[0023] S1: Lay out the lines in advance according to the design specifications and construction requirements, and excavate the trench for placing the corrugated pipe;
[0024] S2: Hoist the two corrugated pipe sections into the trench and adjust them to the appropriate distance;
[0025] S3: Install this device on two corrugated pipe sections. Use the large and small hot melt heating rings to tighten the connection between the two corrugated pipe sections. At the same time, place the pre-prepared heat shrink tape between the small hot melt heating ring and the corresponding corrugated pipe and extend it out of the corrugated pipe.
[0026] S4: Rotate the threaded rotating shaft inside the hollow threaded cylinder, and pull the first support seat and the second support seat closer together through the traction rope, thereby pulling the large hot melt heating ring and the small hot melt heating ring closer together. Then, the two corrugated pipe sections are brought closer together for connection and alignment. During connection, one end of the heat shrink tape is embedded in the large hot melt heating ring. The heat shrink tape seals the interface of the two corrugated pipe sections, while the large hot melt heating ring and the small hot melt heating ring cover the heat shrink tape.
[0027] S5: Power on the large and small hot melt heating coils. The large and small hot melt heating coils convert electrical energy into heat energy to heat the heat shrink tape as a whole. After being heated, the heat shrink tape shrinks and deforms, tightly adhering to the interface of the two corrugated pipes to achieve a sealing connection.
[0028] S6: After the joint between the two corrugated pipes is completely sealed, stop heating and allow the heat shrink tape to cool naturally. Then remove the device. The corrugated pipe connection is now complete.
[0029] This invention provides a corrugated pipe traction connection hot-melt device and its usage method, which has the following beneficial effects;
[0030] 1. The present invention rotates the threaded rotating shaft inside the hollow threaded cylinder, and pulls the first support seat and the second support seat closer together by the traction rope, thereby pulling the large hot melt heating ring and the small hot melt heating ring closer together, and then the two corrugated pipe sections are brought closer together for connection and alignment. This is more convenient and labor-saving than manually pushing the two corrugated pipe sections for traction and alignment connection.
[0031] 2. When connecting corrugated pipes, the protruding end of the heat shrink tape is embedded in the large heat fusion heating coil. The heat shrink tape seals the interface between the two sections of corrugated pipe, while the large and small heat fusion heating coils cover the heat shrink tape. The heat shrink tape is then heated as a whole by energizing the large and small heat fusion heating coils. This method is more efficient than using a blowtorch to heat-melt the heat shrink tape in different parts.
[0032] 3. This invention integrates corrugated pipe traction connection and hot-melt, which not only makes operation convenient, but also improves the overall construction efficiency of corrugated pipe connection and speeds up the construction progress. Attached Figure Description

[0044] Examples, such as Figure 1-6 As shown, a corrugated pipe 100 traction connection hot melt device includes a large hot melt heating coil 1, a small hot melt heating coil 2, a heat shrinkable tape 3, and at least one traction device 4; the large hot melt heating coil 1 and the small hot melt heating coil 2 are made of elastic material and can be electrically heated, and are used to clamp the connection of two sections of corrugated pipe 100 respectively; the heat shrinkable tape 3 is clamped and placed between the small hot melt heating coil 2 and the corresponding corrugated pipe 100 and extends out of the corrugated pipe 100; the traction device 4 is used to pull the large hot melt heating coil 1 and the small hot melt heating coil 2 closer to each other.
[0045] The traction device 4 includes a first support base 41, a second support base 42, a hollow threaded cylinder 43, a threaded rotating shaft 44, and a traction rope 45. The first support base 41 is fixed on the large-sized hot melt heating ring 1. The second support base 42 is fixed on the small-sized hot melt heating ring 2. The hollow threaded cylinder 43 passes through the first support base 41 and the second support base 42, is fixedly connected to the first support base 41, and is slidably connected to the second support base 42. The threaded rotating shaft 44 is located inside the hollow threaded cylinder 43 and is threadedly connected to the hollow threaded cylinder 43. One end of the traction rope 45 is fixedly connected to the second support base 42, and the other end is fixedly connected to the threaded rotating shaft 44.
[0046] In one specific embodiment, the large hot melt heating ring 1 and the small hot melt heating ring 2 are snap-fit structures, which facilitates the clamping of the two corrugated pipe sections 100 and also facilitates the removal of the device after the two corrugated pipe sections 100 are connected.
[0047] Specifically, the buckle structure has an inward-facing beak buckle 5 at one end of its interface, and several buckle interfaces 6 on the outer wall of the other end that cooperate with the beak buckle 5. The beak buckle 5 can be connected by selecting different buckle interfaces 6 according to different corrugated pipe diameters 100.
[0048] In one specific embodiment, there are two traction devices 4, arranged symmetrically, specifically front and back symmetrically, which simultaneously pull the large hot melt heating coil 1 and the small hot melt heating coil 2 closer to each other, improving stability and the accuracy of the corrugated pipe 100 docking.
[0049] In one specific embodiment, the outer surfaces of the large-sized hot-melt heating ring 1 and the small-sized hot-melt heating ring 2 are provided with an insulation layer to prevent burns to construction workers. Specifically, the insulation layer is a mica insulation board.
[0050] In one specific embodiment, the large hot melt heating coil 1 and the small hot melt heating coil 2 are provided with power interfaces 7 for connecting to an external power source.
[0051] In one specific embodiment, the end of the threaded rotating shaft 44 away from the second support 42 has a rotating handle 8 extending out of the hollow threaded cylinder 43, which facilitates the rotation of the threaded rotating shaft 44.
[0052] In one specific embodiment, the traction rope 45 is fixedly connected to the rotating handle or fixedly connected to the threaded rotating shaft 44 through a hole in the hollow threaded cylinder 43.
[0053] The present invention also provides a method for using a corrugated pipe 100 traction connection hot-melt device, comprising the following steps:
[0054] S1: Lay out the lines in advance according to the design specifications and construction requirements, and excavate the trench for placing the corrugated pipe 100. After the excavation is completed, ensure that the trench is flat and free of foreign objects.
[0055] S2: Hoist the two 100mm corrugated pipe sections into the trench and adjust them to the appropriate distance;
[0056] S3: Install this device on two corrugated pipes 100. The large hot melt heating ring 1 and the small hot melt heating ring 2 are respectively tightened at the connection of the two corrugated pipes 100. At the same time, place the pre-prepared heat shrink tape 3 between the small hot melt heating ring 2 and the corresponding corrugated pipe 100 and extend it out of the corrugated pipe 100. The heat shrink tape 3 is clamped by the small hot melt heating ring 2 so that it is tightly attached to the corrugated pipe 100.
[0057] S4: Rotate the threaded rotating shaft 44 inside the hollow threaded cylinder 43, and pull the first support seat 41 and the second support seat 42 closer together through the traction rope 45, thereby pulling the large hot melt heating ring 1 and the small hot melt heating ring 2 closer together, and then the two corrugated pipes 100 are brought closer together for connection and alignment. During connection, one end of the heat shrink tape 3 is embedded in the large hot melt heating ring 1, and the heat shrink tape 3 seals the interface of the two corrugated pipes 100, while the large hot melt heating ring 1 and the small hot melt heating ring 2 cover the heat shrink tape 3.
[0058] Since both the large and small heat-melting heating rings 1 and 2 are made of elastic material, they can be connected by compression. One end of the heat-shrinkable tape 3 can be compressed and embedded into the large heat-melting heating ring 1. Alternatively, a notch can be provided at the bottom of the large heat-melting heating ring 1, allowing the extended end of the heat-shrinkable tape 3 to be directly embedded into the notch. When rotating the threaded shaft 44, the operator must rotate it at a uniform speed, avoiding excessive speed to prevent stripping of the internal threads and malfunction of the rotating device.
[0059] S5: Power on the large hot melt heating coil 1 and the small hot melt heating coil 2. The large hot melt heating coil 1 and the small hot melt heating coil 2 convert electrical energy into heat energy to heat the heat shrink tape 3 as a whole. After being heated, the heat shrink tape 3 shrinks and deforms, and tightly adheres to the interface of the two corrugated pipes 100 to achieve the function of sealing connection.
[0060] S6: After the joint of the two corrugated pipes 100 is completely sealed, stop heating and allow the heat shrink tape 3 to cool naturally. Then remove the device. The connection of the corrugated pipes 100 is now complete.
[0061] This invention rotates the threaded rotating shaft 44 inside the hollow threaded cylinder 43, pulling the first support seat 41 and the second support seat 42 closer together via the traction rope 45. This, in turn, pulls the large heat-melting ring 1 and the small heat-melting ring 2 closer together, thereby connecting and aligning the two sections of corrugated pipe 100. This is more convenient and labor-saving than manually pushing the two sections of corrugated pipe 100 for connection and alignment. When connecting the corrugated pipe 100, one end of the heat-shrinkable tape 3 is embedded in the large heat-melting ring 1, sealing the interface between the two sections of corrugated pipe 100. The large heat-melting ring 1 and the small heat-melting ring 2 then cover the heat-shrinkable tape 3. By energizing the large heat-melting ring 1 and the small heat-melting ring 2, the heat-shrinkable tape 3 is heated as a whole. This is more efficient than using a blowtorch to heat-melt the heat-shrinkable tape 3 at different points. This invention integrates the traction connection and hot-melt of the corrugated pipe 100, which not only makes operation convenient but also improves the overall construction efficiency of the corrugated pipe 100 connection and speeds up the construction progress.
[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
