Description

Technical Field

[0001] The present invention relates to the technical field of water supply, and in particular to supporting equipment and a construction method for hot-melt pipe processing. Background Art

[0002] Currently, urban water pipes are often made of corrosion-resistant, high-strength polyethylene materials such as PE / PPR, which offer low cost, long service life, and easy construction. Water pipes typically consist of several pipe sections, with adjacent sections sealed and fixed using hot-melt connections.

[0003] Pipe hot melt is a key and difficult point in the construction process. The quality of pipe hot melt directly affects the success of tap water construction. At present, the construction process of tap water pipelines has the following shortcomings: (1) Before welding the pipes, at least two workers are required to prepare the two pipe heads at the joint in advance to facilitate the butt-jointing of the pipes to be hot-melted and ensure that the pipes on both sides fit tightly together. In the process of grinding the pipe heads, because the water pipes are often long, manual grinding is more difficult, and there are no fixed measures for grinding construction at this stage, resulting in uneven grinding quality, which affects the quality of hot-melt welding after the butt-jointing is completed; (2) During the pipe welding process, because there are no fixed measures on the hot melt machine and its two sides, it is necessary for a worker to stand on each side to hold the pipes on both sides, and a worker to operate the hot melt machine to perform the hot melting operation, which seriously affects the construction progress and consumes manpower and is inefficient; (3) After the hot melt is completed, the temperature of the PE / PPR pipe at the interface is high and the hardness is low, so the two welded pipes need to be cooled. During the cooling process, the pipe body can be immediately corrected, but rotation is strictly prohibited. At this stage of construction, there is no pipe cooling limit equipment, which cannot solve the problem of pipe twisting, bending, and deformation caused by uneven placement area or external force. Summary of the Invention

[0004] In order to overcome the problem in the above-mentioned background technology that "the lack of limiting support equipment during the pipe hot melting process will lead to increased manpower requirements, cumbersome operating steps, reduced construction efficiency and reduced construction quality", the present invention provides a support equipment and construction method for hot-melt pipe processing.

[0007] As a further optimization scheme of the present invention, a first slide groove with an open top surface is provided in the first crossbeam, the cross-section of the first slide groove is convex, and the first slide groove is arranged along the length direction of the first crossbeam; a first slider is provided at the bottom end of the column, and the column and the first slider are fixedly connected in a ⊥ shape; the first slider is arranged in the first slide groove and can slide back and forth along the length direction of the first slide groove.

[0008] As a further optimization solution of the present invention, the top surface, side wall and bottom surface of the first sliding block are respectively provided with rotatable first rollers, and the first rollers are adapted and press-fitted with the inner wall of the first sliding groove.

[0009] As a further optimization solution of the present invention, the bottom end of the column is inserted into the top position of the inner cavity of the first chute.

[0010] As a further optimization scheme of the present invention, the first support seat includes a beam group and a connecting beam, the beam group is provided with two and is arranged parallel to each other, and the connecting beam is provided with two and is arranged parallel to each other; the beam group and the connecting beam are fixedly connected in a U-shape.

[0011] As a further optimization scheme of the present invention, a single beam group includes a supporting beam and two limiting beams; a sleeve is provided at the bottom end of the column, and the column and the sleeve are fixedly connected in a ⊥ shape; the sleeve is sleeved on the surface of the limiting beam and can slide along the length direction of the limiting beam; each of the bottom ends of the columns is connected to one of the sleeves, and each of the limiting beam surfaces is sleeved with at least one of the sleeves.

[0012] As a further optimization solution of the present invention, the top surface, side wall and bottom surface of the inner cavity of the sleeve are respectively provided with second rotatable rollers, and the second rollers are adapted to be press-fitted with the limiting beam.

[0013] As a further optimization scheme of the present invention, a detachable replacement sleeve is installed in the top plate of the sleeve, and a height-adjustable limit bolt is provided in the replacement sleeve; the bottom end of the limit bolt can be pressed against the top surface of the limit beam to limit the sleeve and the column.

[0014] A construction method for support equipment for hot-melt pipe processing, which uses the support equipment for hot-melt pipe processing to support and limit the pipe, and the steps include: S1, taking a number of the support equipment for hot-melt pipe processing, and placing the first pipe section and the second pipe section in the pipe on the second support seat respectively; S2, moving the first pipe section and the second pipe section to a coaxial state with their ends abutting each other; S3, moving the column so that the column clamps the first pipe section from both sides; S4, moving the column so that the column clamps the second pipe section from both sides; S5, fixing the mutually abutting parts of the first pipe section and the second pipe section by hot-melt welding.

[0015] In summary, the present invention has at least one of the following advantages: (1) The present invention has a simple structure and reliable functions. The pipe clamp assembly includes a plurality of columns, which abut against the pipe laterally and apply pressure to the pipe, thereby replacing manpower to limit the position of the pipe, thereby keeping the first pipe section and the second pipe fitting in the pipe aligned, thereby reducing the number of workers required, simplifying the operation steps, and improving construction efficiency and quality.

Then the minimum vertical spacing between the two columns is 0, so that pipes with smaller outer diameters can be clamped, avoiding the problem that the two first sliders abut against each other and can only clamp pipes with an outer diameter ≥ 2a.

[0020] (6) The sleeve is mounted on the outer periphery of the limiting beam, and the second roller is pressed against the plane of the surface of the limiting beam. It has higher environmental adaptability and can prevent impurities (such as dust, mud spots, etc.) from falling into the first slide groove and causing the first slider to be stuck. The outer surface of the limiting beam is rectangular and has no groove structure, so it is more convenient to wash away impurities adhering to the outer surface of the limiting beam with water or wind, thereby avoiding the problem of the sleeve being stuck.

[0023] Based on the above structural features of the present application, the implementation methods of the present application are further described: Reference Figures 1 and 2This embodiment provides a support device for hot-melt pipe processing, including a first support base 1, a second support base 2, a pipe clamp assembly 3 and a height adjustment assembly 4; the height adjustment assembly 4 is arranged longitudinally, and the bottom end of the height adjustment assembly 4 is connected to the first support base 1 and the top end is connected to the second support base 2. The height adjustment assembly 4 can drive the second support base 2 to move longitudinally, so that the height of the second support base 2 adapts to the position of the pipe 5, and then the second support base 2 can adaptably and stably support the pipe 5.

[0024] Reference Figures 1 to 3 、 Figure 7 and Figure 16 The pipe clamp assembly 3 includes several columns 31 for retaining the pipe 5. The bottom ends of the columns 31 are slidably connected to the first support base 1. The columns 31 can move laterally and abut the pipe 5 from the side. The columns 31 abut the pipe 5 from the side and apply pressure to the pipe 5, thereby retaining the pipe 5 and aligning the first pipe section 51 and the second pipe fitting within the pipe 5, facilitating subsequent welding operations. The columns 31 are straight rod-shaped.

[0025] Reference Figure 3 The first support base 1 includes a first crossbeam 21 and a second crossbeam 22. Two first crossbeams 21 are provided and arranged parallel to each other, and two second crossbeams 22 are provided and arranged parallel to each other. The first crossbeams 21 and the second crossbeams 22 are fixedly connected in an L-shape. Adjacent ends of the first crossbeam 21 and the second crossbeam 22 are fixedly connected in an L-shape (for example, by bolts, an integral fixed connection, or welding). Both the first crossbeam 21 and the second crossbeam 22 are straight rod-shaped structures.

[0026] Reference Figures 3 to 6 The first slide 211 is provided with a first slide groove 211 with an opening on the top surface in the first crossbeam 21, and the first slide groove 211 is a straight groove; the cross-section of the first slide groove 211 is convex, and the length direction of the first slide groove 211 is arranged along the length direction of the first crossbeam 21; the bottom end of the column 31 is provided with a first slider 32, and the outer wall of the first slider 32 is adapted to the inner wall of the lower portion of the first slide groove 211; the column 31 and the first slider 32 are fixedly connected in a ⊥ shape (for example, by bolts, welding or integrated fixed connection), and the bottom end of the column 31 is located at the center position of the length direction of the top surface of the first slider 32; the first slider 32 is arranged in the first slide groove 211 and can slide back and forth along the length direction of the first slide groove 211, and the column 31 and the first slider 32 slide back and forth synchronously along the length direction of the first slide groove 211, thereby adjusting the distance between two adjacent columns 31, so that the two columns 31 can adapt to clamp the tube body from both sides.

[0027] Reference Figures 4 and 5The top surface, side wall and bottom surface of the first slider 32 are respectively provided with a plurality of rotatable first rollers 321 (a rotating shaft is inserted in the middle of the first roller 321, and both ends of the rotating shaft are connected to the first slider 32 through a shaft seat; a bearing is installed between the rotating shaft and the first rollers 321), and the first rollers 321 are adapted and pressed against the inner wall of the first slide groove 211; when the first slider 32 moves in the first slide groove 211, the first rollers 321 are pressed against the inner wall of the first slide groove 211 and roll, thereby reducing the friction between the first slider 32 and the first slide groove 211, thereby improving the smoothness of movement of the first slider 32, and improving the smoothness and convenience of the user in pushing the column 31 to move.

[0028] Reference Figures 4 and 5 The bottom end of the column 31 is inserted into the top position of the inner cavity of the first slide groove 211. The width of the column 31 is smaller than the width of the top of the first slide groove 211, avoiding the problem that the bottom end of the column 31 is stuck in the first slide groove 211.

[0029] Reference Figure 7 , take four hot melt pipe processing support devices, two of which are used to support the two ends of the first pipe section 51, and the other two are used to support the two ends of the second pipe section 52; the column 31 is used to clamp the first pipe section 51 and the second pipe section 52 from both sides, so as to limit the position of the first pipe section 51 and the second pipe fitting after they are aligned, so as to facilitate the later welding of the first pipe section 51 and the second pipe section 52.

[0030] Reference Figure 8 Since the column 31 and the first slider 32 are fixedly connected in a ⊥ shape, this embodiment can clamp the pipe 5 / first pipe section 51 / second pipe section 52 with an outer diameter of not less than 2a (the vertical distance between the side wall of the column 31 and the end face of the first slider 32 on the same side is a).

[0031] Reference Figure 9 and Figure 10 The first support seat 1 includes a beam group 23 and a connecting beam 24. There are two beam groups 23 and they are arranged parallel to each other. There are two connecting beams 24 and they are arranged parallel to each other. The beam group 23 and the connecting beam 24 are fixedly connected in a U-shaped manner (for example, by welding, bolts or an integrated fixed connection).

[0032] Reference Figure 9 and Figure 10A single beam assembly 23 includes a supporting beam 231 and two limiting beams 232. The two limiting beams 232 are disposed on either side of the supporting beam 231 and are arranged parallel to each other. The supporting beam 231 is vertically fixedly connected to the two connecting beams 24 at both ends (e.g., by welding, bolting, or an integral connection). The limiting beam 232 is vertically fixedly connected to the two connecting beams 24 at both ends (e.g., by welding, bolting, or an integral connection).

[0033] Reference Figures 10 to 13 A sleeve 33 is provided at the bottom end of the column 31. The sleeve 33 is straight and has a rectangular cross-section. The column 31 and sleeve 33 are fixedly connected in a V-shape (e.g., by welding, bolting, or an integral connection). The bottom end of the column 31 is located at the center of the top surface of the sleeve 33. The sleeve 33 is mounted on the surface of the limiting beam 232 and can slide along the length of the limiting beam 232. The inner wall of the sleeve 33 adapts to the outer wall of the limiting beam 232, ensuring smooth sliding of the sleeve 33.

[0034] Reference Figure 10 and Figure 16 The bottom end of each column 31 is connected to a sleeve 33, and the surface of each limiting beam 232 is at least provided with a sleeve 33.

[0035] Reference Figure 10 、 Figure 11 and Figure 16 The two limiting beams 232 in the same beam group 23 are each connected to at least one column 31, that is, the same beam group 23 is provided with at least two columns 31, and the two sleeves 33 corresponding to the two columns 31 are respectively connected to different limiting beams 232, that is, the two sleeves 33 are not collinear and can be staggered to achieve gaps, then the minimum vertical spacing L between the two columns 31 is 0, so that the pipe 5 / first pipe section 51 / second pipe section 52 with a smaller outer diameter can be clamped (there is no restriction on the minimum outer diameter limit of 2a).

[0036] Reference Figure 12 , the top surface height of the supporting crossbeam 231 is not lower than the top surface height of the sleeve 33, so that the pipe 5 / first pipe section 51 / second pipe section 52 can be stably pressed against the upper surface of the supporting crossbeam 231, avoiding the problem of the top sharp corner of the end face of the sleeve 33 squeezing the surface of the pipe 5 / first pipe section 51 / second pipe section 52 (the top sharp corner squeezing the pipe 5 / first pipe section 51 / second pipe section 52 will cause scratches on their outer surfaces and may even cause concentrated force and structural damage, such as penetrating damage to the side wall).

[0037] Reference Figure 13、 Figure 14 and Figure 15 Rotatable second rollers 331 are mounted on the top, sidewalls, and bottom of the inner cavity of the sleeve 33. A rotating shaft is inserted into the middle of the second roller 331, and its ends are connected to the sleeve 33 via shaft seats or bolts; the second roller 331 and the rotating shaft are connected via bearings. The second rollers 331 are press-fitted against the limiting beam 232. When the sleeve 33 slides, the second rollers 331 press-fit against the limiting beam 232 and roll, thereby reducing the sliding friction between the sleeve 33 and the limiting beam 232 and improving the smoothness of movement of the sleeve 33 and the column 31.

[0038] Reference Figure 13 and Figure 14 A removable replacement sleeve 334 is installed within the top plate of sleeve 33. A height-adjustable stopper bolt is located within the stopper bolt 334. The bottom end of the stopper bolt can press against the top surface of the stopper beam 232, thereby securing the sleeve 33 and the column 31 and thereby ensuring a stable clamping of the pipe body. A longitudinally arranged first screw hole is provided within the interior of sleeve 33. The stopper bolt is inserted into the first screw hole and threadedly connected. When the user rotates the stopper bolt, its height can be adjusted, thereby achieving pressurization and disengagement between the stopper bolt and the stopper beam 232.

[0039] Reference Figure 13 and Figure 14 The limiting bolt is an eyebolt 332 or a hexagonal bolt 333. The user manually grabs the eye of the eyebolt 332 to quickly rotate the eyebolt 332; the user inserts a crowbar into the eye to rotate the eyebolt 332, thereby tightening or loosening the eyebolt 332 and the limiting beam 232. The user manually grabs the stud of the hexagonal bolt 333 to quickly rotate the hexagonal bolt 333; the user uses a wrench (manual wrench or electric wrench) to rotate the hexagonal bolt 333, thereby tightening or loosening the hexagonal bolt 333 and the limiting beam 232. The user also uses a wrench (manual wrench or electric wrench) to quickly rotate the hexagonal bolt 333.

[0040] Reference Figure 13 and Figure 14 The top plate of sleeve 33 has a through-hole countersunk hole. Replacement sleeve 334 is inserted into the countersunk hole. An annular fin (e.g., bolted) is provided on the top of the outer wall of replacement sleeve 334 and fits over the upper portion of the countersunk hole. The annular fin is detachably connected to sleeve 33 (e.g., bolted). Because the stop bolt requires frequent rotation, if the first threaded hole in replacement sleeve 334 wears out, the user can replace it with a new replacement sleeve 334 and a new stop bolt.

[0041] Reference Figure 16, take four hot melt pipe processing support devices, two of which are used to support the two ends of the first pipe section 51, and the other two are used to support the two ends of the second pipe section 52; the column 31 is used to clamp the first pipe section 51 and the second pipe section 52 from both sides, so as to limit the position of the first pipe section 51 and the second pipe fitting after they are aligned, so as to facilitate the later welding of the first pipe section 51 and the second pipe section 52.

[0042] Reference Figure 17 and Figure 20 , the height adjustment component 4 is divided into automatic adjustment and manual adjustment.

[0043] Reference Figure 17 and Figure 18 The height adjustment assembly 4 includes a scissor-type telescopic structure and a connecting rod 42.

The telescopic structure includes a first rod body 411 and a second rod body 412. There are a plurality of first rod bodies 411 and arranged parallel to each other, and a plurality of second rod bodies 412 and arranged parallel to each other. The first rod bodies 411 and the second rod bodies 412 of the same height are arranged in an X-shape and are rotatably connected. The middle portion of the first rod body 411 and the middle portion of the second rod body 412 of the same height are rotatably connected via a rotating shaft. The end portions of the first rod body 411 and the end portions of the second rod body 412 that are adjacent to each other are rotatably connected (for example, via a rotating shaft). The first rod body 411 and the second rod body 412 form a telescopic diamond structure that can be extended and retracted, namely, a scissor-type telescopic structure. The two telescopic structures are connected by a plurality of connecting rods 42. The ends of the connecting rods 42 are rotatably connected to the connection position of the end portions of the first rod body 411 and the end portions of the second rod body 412. A support tube 421 is inserted and fixed to the end of the connecting rod 42 (e.g., via a bolted connection). A stop ring 4211 is fixedly mounted on the end of the support tube 421 away from the connecting rod 42 (e.g., via an integral fixed connection). The ends of the first rod 411 and the second rod 412 are each provided with a socket for accommodating the support tube 421. The first and second rod 411, 412 ends are each sleeved onto the outer wall of the support tube 421 and positioned between the connecting rod 42 and the stop ring 4211. The first rod 411 can rotate about the support tube 421, and the second rod 412 can rotate about the support tube 421. The support tube 421, stop ring 4211, and connecting rod 42 are coaxially arranged.

[0044] A bearing is provided between the support tube 421 and the first rod body 411 , and a bearing is provided between the support tube 421 and the second rod body 412 , thereby improving the telescopic smoothness of the telescopic structure.

[0045] Reference Figure 19The two connecting rods 42 at the same height are connected by a pulling screw 43. One end of the pulling screw 43 is annularly clamped with one of the connecting rods 42, and the other end is connected to the other connecting rod 42 through a thread. When the pulling screw 43 rotates, it can drive the two connecting rods 42 to move closer or farther away from each other, thereby realizing the height adjustment of the telescopic structure, that is, realizing the height adjustment of the height adjustment component 4.

[0046] Reference Figure 19 The two connecting rods 42 located at the same height are connecting rod a42a and connecting rod b42b respectively; the connecting rod a42a, connecting rod b42b and the tension screw 43 are connected in a stem shape. The left end of the tension screw 43 is fixedly sleeved with two stop ring bodies 431 (for example, fixedly connected by bolts), and the right end is provided with an external thread. A socket is provided in the middle of the connecting rod a42a, and the left end of the tension screw 43 is inserted into the socket. The two stop ring bodies 431 are respectively provided on both sides of the connecting rod a42a, and the tension screw 43 can rotate in the socket and avoid falling out of the socket. A second screw hole is provided in the middle of the connecting rod b42b, and the right end of the tension screw 43 is inserted into the second screw hole and connected by threads. A crank handle 44 is fixedly installed at the right end surface of the pulling screw 43 (for example, fixedly connected by a bolt). The user grasps and turns the crank handle 44 to drive the pulling screw 43 to rotate, and then drives the connecting rod a42a and the connecting rod b42b to move closer to or away from each other, thereby achieving height adjustment of the height adjustment component 4, that is, manual adjustment of the height adjustment component 4.

[0047] Reference Figure 20 The two connecting rods 42 at different heights are connected by a hydraulic cylinder 45 (the two connecting rods 42 are connected to different first connecting rods; the two connecting rods 42 are connected to different second connecting rods). The two connecting rods 42 are respectively inserted into the shaft sleeves at both ends of the hydraulic cylinder 45 to realize rotational connection; during the extension and retraction process of the hydraulic cylinder 45, the telescopic structure is driven to realize height adjustment, that is, the height adjustment of the height adjustment component 4 is realized.

[0048] Hydraulic cylinder 45 is connected to an oil pump via a plurality of first oil pipes, which in turn are connected to an oil tank via a plurality of second oil pipes. Both the oil pump and oil tank are bolted securely to a housing on the top surface of first support base 1. The housing is bolted to one end of first support base 1, thereby allowing the telescopic structure to move freely. The oil pump is connected to an external power supply via wires.

[0049] Reference Figure 17The first rod 411 and the second rod 412 rotate crosswise to achieve height adjustment. During this process, the distance between the top of the first rod 411 and the top of the second rod 412 changes, and the distance between the bottom of the first rod 411 and the bottom of the second rod 412 changes. The first support base 1 includes two first crossbars 11 and two second crossbars 22. There are two first crossbars 11 and they are arranged parallel to each other. There are two second crossbars 12 and they are arranged parallel to each other. The two first crossbars 11 and the two second crossbars 12 are fixedly connected in a U-shaped manner (for example, by bolts, welding, or integrated fixed connection).
