Description

Technical Field

[0001] The invention relates to the technical field of HDPE water supply pipe connection equipment, in particular to energy-saving HDPE water supply pipe rapid cooling equipment. Background Art

[0002] Energy-saving HDPE water pipes can resist the erosion of various chemical media and will not rust or corrode as easily as metal pipes, greatly extending their service life. When conveying fluids containing corrosive substances, no additional anti-corrosion measures are required, reducing maintenance costs. At the same time, HDPE has a tight molecular structure and high wear resistance, and can withstand the friction of particles carried in the water flow. It is suitable for fields such as mud transportation, reducing pipe wear and replacement frequency.

[0003] However, when two sections of HDPE water pipes are hot-melt connected, curling is likely to occur on the inner wall of the pipe, which not only reduces the inner diameter of the inner wall of the pipe, but may also form a funnel-shaped water plug at the curling edge, which will block the water flow channel. While reducing the drainage flow, the water flow may produce unstable flow states such as eddy currents and turbulence, increase water flow resistance, and cause the water delivery capacity of the pipe to decrease. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an energy-saving HDPE water supply pipe rapid cooling device, comprising a table top, a fixed plate is fixedly connected to the top of the table top, a fixed block 1 is fixedly connected to the side of the top of the table top close to the fixed plate, a spring auxiliary roller is arranged above the fixed block 1, the number of the spring auxiliary rollers is two, the two spring auxiliary rollers are symmetrically arranged with the fixed cylinder 1, the front of the fixed block 1 is fixedly connected to the fixed cylinder 1, the top of the fixed block 1 is fixedly connected to the side of the fixed cylinder 1, and the right side of the fixed rod is rotatably connected to a clamping auxiliary wheel; The cooling assembly includes a motor, the output end on the right side of the motor is fixedly connected to an auger through a coupling, the outer surface of the auger is fixedly connected to a pulley 1, the outer surface of the pulley 1 is transmission-connected to a belt, a rotating hole is opened on the right side of the fixed block 1, the inner wall of the rotating hole is rotationally connected to a water inlet pipe, the outer surface of the water inlet pipe is fixedly connected to a pulley 2, and the pulley 2 is transmission-connected to the pulley 1 through a belt; The smoothing component includes a limit column, the outer surface of the limit column is rotatably connected with a spring telescopic cylinder 1, the front of the spring telescopic cylinder 1 is rotatably connected with a rotating plate, the side of the spring telescopic cylinder 1 away from the rotating plate is rotatably connected with a hydraulic cylinder 1, the right side of the hydraulic cylinder 1 is fixedly connected with a hydraulic cylinder 2, and the front of the hydraulic cylinder 2 is fixedly connected with a smoothing plate. The movement of the pipeline will cause the rotating plate to enter the interior of the pipeline. Since the outer side of the rotating plate is larger than the inner diameter of the pipeline, the rotating plate will rotate when entering the pipeline, so that the rotating plate fits with the inner wall of the pipeline. The fitted rotating plate will continue to move in the pipeline. During the movement, the two spring expansion cylinders 1 rotate around the limit column. The continuous rotation of the spring expansion cylinder 1 will transport the liquid in the hydraulic cylinder 1 to the hydraulic cylinder 2. Due to the increase in the volume of the liquid in the hydraulic cylinder 2, the two smoothing plates will move outward and contact the curled edge of the inner wall of the pipe to smooth it, thereby preventing the curled edge from cooling down without being smoothed, which will cause the inner diameter of the pipe to become smaller in subsequent use, and a funnel-shaped water plug may be formed at the curled edge, which will cause the water flow rate inside the pipe to decrease, increase the water flow resistance, and allow the pipe to be used normally after hot-melt connection.

[0005] Preferably, a fixing block 2 is provided on the right side of the clamping auxiliary wheel, and a spring auxiliary wheel is fixedly connected to the top of the fixing block 2. There are several spring auxiliary wheels, and the several spring auxiliary wheels are arranged in a circular array. The arrangement of several spring auxiliary wheels can also play an auxiliary smoothing effect.

[0006] Preferably, a water delivery pipe is fixedly connected to the top of the water inlet pipe, a water outlet nozzle is fixedly connected to the bottom of the water delivery pipe, a toothed belt 1 is meshedly connected to the bottom of the auger, the inner wall of the toothed belt 1 contacts a rotating wheel, a rotating column is fixedly connected to the front of the rotating wheel, a moving rod 1 is rotatably connected to the front of the rotating column, a water tank is fixedly connected to the right side of the moving rod 1, a one-way valve is fixedly connected to the left side of the water tank, an annular nozzle is fixedly connected to the right side of the water tank, and the right side of the water outlet nozzle is fixedly connected to the left side of the fixed block 2. Before use, the water pipe is first connected to the water inlet pipe and the one-way valve, and then the auger is rotated by starting the motor. The rotation of the auger will cause the pulley 1 and the belt to drive the water inlet pipe to rotate, and the water in the water inlet pipe will flow through The water is sprayed out from the water outlet nozzle through the water delivery pipe, so as to cool down the inner wall of the pipe after the hot-melt connection is smoothed. At the same time, the rotation of the auger will move the toothed belt one, and the movement of the toothed belt one will drive the rotating wheel to move synchronously. The movement of the rotating wheel will cause the rotating column to drive the moving rod one to reciprocate. When the moving rod one pushes the water tank, the water in the water tank will be squeezed and sprayed out from the annular nozzle to cool the hot-melt connection on the outer surface of the pipe, so that the inner and outer walls of the pipe are cooled at the same time. Compared with the previous single outer wall cooling, the simultaneous cooling of the inner and outer walls will make the cooling efficiency of the inner and outer walls the same, so as to avoid bending or even cracking of pipes with different cooling efficiencies.

[0007] Preferably, a fixed cylinder 2 is fixedly connected to the right side of the water inlet pipe, a rotating groove is opened on the front side of the fixed cylinder 2, a limiting column is fixedly connected to the inner wall of the rotating groove, a fixed hole is opened on the right side of the fixed cylinder 2, the inner wall of the fixed hole is fixedly connected to the outer surface of the water pipe, the number of spring telescopic cylinders 1 is two, the two spring telescopic cylinders 1 are symmetrically arranged with the hydraulic cylinder 1 as the center, a spring is sleeved on the outer surface of the hydraulic cylinder 1, the number of hydraulic cylinders 2 is two, the two hydraulic cylinders 2 are symmetrically arranged with the water pipe as the center.

[0008] Preferably, a conveying assembly is provided on the right side of the hydraulic cylinder two, and the conveying assembly includes a fixed block three, a conveying groove is opened on the top of the fixed block three, and the inner wall of the conveying groove is rotatably connected to a toothed conveyor belt through a rotating shaft, and the bottom of the toothed conveyor belt is meshed and connected with the top of the auger, and a connecting block is fixedly connected to the right side of the fixed block three.

[0009] Preferably, a rotating rod is rotatably connected to the back of the connecting block through a pin shaft, and there are two rotating rods. The two rotating rods are symmetrically arranged with the connecting block as the center, and the front side of the rotating rod located at the back is rotatably connected to a conveying auxiliary wheel, so that the pipe after hot-melt connection is placed on the toothed conveyor belt. Since the conveying auxiliary wheel is affected by gravity, the rotating rod drives it to rotate so that it is level with the toothed conveyor belt, and then the auger is rotated under the start of the motor. Since the toothed conveyor belt and the auger are meshingly connected, the toothed conveyor belt will move, driving the pipe to move, and the conveying auxiliary wheel can also play an auxiliary transportation effect. At the same time, the rotating roller will also shrink when the rotating rod rotates to avoid affecting the moving pipe. Subsequently, the conveyed pipe will contact the spring auxiliary roller and the clamping auxiliary wheel. Compared with the previous manual assembly, the automatically conveyed pipe can not only simplify the assembly process, but also make the assembly faster, avoiding the problem of slow assembly and gradual hardening of the curling edge of the inner wall of the pipe after hot-melt connection.

[0010] Preferably, an auxiliary rotating assembly is provided on the front side of the rotating rod, and the auxiliary rotating assembly includes a rotating block, the back side of the rotating block is rotatably connected to the front side of the rotating rod through a pin shaft, the left side of the rotating block is fixedly connected to a moving rod 2, the back side of the moving rod 2 is fixedly connected to a limiting block 1, the back side of the limiting block 1 contacts the limiting block 2, and the back side of the limiting block 2 is fixedly connected to a rotating roller.

[0011] Preferably, a spring telescopic cylinder three is fixedly connected to the side of the back side of the rotating roller close to the limit block two, and the front side of the rotating rod located at the front is rotatably connected to the spring telescopic cylinder two, and an assembly groove is opened on the right side of the fixed block three, and the inner wall of the assembly groove is fixedly connected to the side of the spring telescopic cylinder two away from the rotating rod. When the tail of the pipeline leaves the conveying auxiliary wheel, the rotating rod can be reset to its original state under the action of the spring telescopic cylinder two, and the movement of the rotating rod will cause the rotating block to drive the moving rod two to move, and the movement of the moving rod two will cause the limit block one to lift the limit block two, so that the rotating roller moves toward the pipeline. At the same time, the spring telescopic cylinder three will also be deformed under the movement of the limit block one, and the contact between the rotating roller and the pipeline will assist the rotation of the pipeline, thereby avoiding excessive speed difference between the two sections of the pipe, cracking at the hot-melt connection, and also avoiding the problem of bending of the pipeline when it is cooled.

[0012] The present invention has the following beneficial effects: (1) The present invention causes the rotating plate to enter the interior of the pipeline through the movement of the pipeline. Since the outer side of the rotating plate is larger than the inner diameter of the pipeline, the rotating plate will rotate when entering the interior of the pipeline, so that the rotating plate fits against the inner wall of the pipeline. The fitted rotating plate will cause the two spring telescopic cylinders 1 to rotate around the limit column as the pipeline continues to move. The continuous rotation of the spring telescopic cylinder 1 will transport the liquid in the hydraulic cylinder 1 to the hydraulic cylinder 2. Due to the increase in the volume of the liquid in the hydraulic cylinder 2, the two smoothing plates will move outward and contact the curling edge of the inner wall of the pipeline to smooth it, thereby preventing the curling edge from cooling without being smoothed, thereby causing the inner diameter of the pipeline to become smaller in subsequent use, and a funnel-shaped water plug may be formed at the curling edge, thereby causing the flow rate of water in the pipeline to decrease, increasing the water flow resistance, and allowing the pipeline to be used normally after hot-melt connection.

[0013] (2) Before use, the present invention connects the water pipe to the water inlet pipe and the one-way valve, and then starts the motor to rotate the auger. The rotation of the auger causes the pulley 1 and the belt to drive the water inlet pipe to rotate, and the water in the water inlet pipe is sprayed out from the water outlet nozzle through the water pipe, so as to cool down the inner wall of the pipe after the hot-melt connection is smoothed. At the same time, the rotation of the auger causes the toothed belt 1 to move, and the movement of the toothed belt 1 drives the rotating wheel to move synchronously. The movement of the rotating wheel causes the rotating column to drive the moving rod 1 to reciprocate. When the moving rod 1 pushes the water tank, it squeezes the water in the water tank and sprays it out from the annular nozzle, cooling the hot-melt connection on the outer surface of the pipe, so that the inner and outer walls of the pipe are cooled at the same time. Compared with the previous single outer wall cooling, the simultaneous cooling of the inner and outer walls makes the cooling efficiency of the inner and outer walls the same, avoiding the bending or even cracking of pipes with different cooling efficiencies.

[0014] (3) The present invention places the pipe after hot-melt connection on the toothed conveyor belt. Since the conveying auxiliary wheel is affected by gravity, the rotating rod drives it to rotate so that it is level with the toothed conveyor belt. Then, the auger is rotated under the start of the motor. Since the toothed conveyor belt and the auger are meshingly connected, the toothed conveyor belt will move, driving the pipe to move. The conveying auxiliary wheel can also play an auxiliary transportation effect. At the same time, the rotating roller will also shrink when the rotating rod rotates to avoid affecting the moving pipe. Then, the conveyed pipe will contact the spring auxiliary roller and the clamping auxiliary wheel. Compared with the previous manual assembly, the automatically conveyed pipe can not only simplify the assembly process, but also make the assembly faster, avoiding the problem of slow assembly and gradual hardening of the curled edge of the inner wall of the pipe after hot-melt connection.

[0015] (4) In the present invention, when the tail of the pipeline leaves the auxiliary conveying wheel, the rotating rod can be reset to its original state under the action of the spring telescopic cylinder 2. The movement of the rotating rod will cause the rotating block to drive the moving rod 2 to move. The movement of the moving rod 2 will cause the limit block 1 to lift the limit block 2, so that the rotating roller moves toward the pipeline. At the same time, the spring telescopic cylinder 3 will also be deformed under the movement of the limit block 1. The contact between the rotating roller and the pipeline will assist the rotation of the pipeline, thereby avoiding a large speed difference between the two sections of the pipe and cracking at the hot melt connection. At the same time, it also avoids the problem of bending of the pipeline when it is cooled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

The movement of the pipeline will cause the rotating plate 421 to enter the interior of the pipeline. Since the outer side of the rotating plate 421 is larger than the inner diameter of the pipeline, the rotating plate 421 will rotate when entering the pipeline, so that the rotating plate 421 fits against the inner wall of the pipeline. The rotating plate 421 at the rear will cause the two spring telescopic cylinders 42 to rotate around the limit column 411 during the continuous movement of the pipeline. The continuous rotation of the spring telescopic cylinder 42 will transport the liquid in the hydraulic cylinder 43 to the hydraulic cylinder 2 44. The increase in the liquid volume in the hydraulic cylinder 2 44 will cause the two smoothing plates 441 to move outward and contact the curled edge of the inner wall of the pipeline to smooth it, thereby preventing the curled edge from cooling without being smoothed, which will cause the inner diameter of the pipeline to become smaller during subsequent use, and a funnel-shaped water plug may be formed at the curled edge, thereby reducing the flow rate of water inside the pipeline and increasing the water flow resistance, so that the pipeline connected by hot melt can be used normally.

When the pipe 32 rotates, the water in the water inlet pipe 32 will be sprayed out from the water outlet nozzle 323 through the water delivery pipe 322, so as to cool down the inner wall of the pipe after the hot-melt connection is smoothed. At the same time, the rotation of the auger 311 will move the toothed belt 33, and the movement of the toothed belt 33 will drive the rotating wheel 331 to move synchronously. The movement of the rotating wheel 331 will cause the rotating column 332 to drive the moving rod 34 to reciprocate. When the moving rod 34 pushes the water tank 35, the water in the water tank 35 will be squeezed and sprayed out from the annular nozzle 352 to cool the hot-melt connection on the outer surface of the pipe, so that the inner and outer walls of the pipe are cooled at the same time. Compared with the previous single outer wall cooling, the simultaneous cooling of the inner and outer walls will make the cooling efficiency of the inner and outer walls the same, so as to avoid bending or even cracking of pipes with different cooling efficiencies.

[0023] A fixed cylinder 2 41 is fixedly connected to the right side of the water inlet pipe 32, a rotating groove is opened on the front side of the fixed cylinder 2 41, a limiting column 411 is fixedly connected to the inner wall of the rotating groove, a fixing hole is opened on the right side of the fixed cylinder 2 41, the inner wall of the fixing hole is fixedly connected to the outer surface of the water pipe 322, there are two spring telescopic cylinders 1 42, the two spring telescopic cylinders 1 42 are symmetrically arranged with the hydraulic cylinder 1 43 as the center, a spring 431 is sleeved on the outer surface of the hydraulic cylinder 1 43, there are two hydraulic cylinders 2 44, the two hydraulic cylinders 2 44 are symmetrically arranged with the water pipe 322 as the center.

[0024] For example 2, please refer to Figure 6-Figure 8 The present invention is an energy-saving HDPE water supply pipe rapid cooling device. On the basis of the first embodiment, a conveying assembly 5 is arranged on the right side of the hydraulic cylinder 44, and the conveying assembly 5 includes a fixed block 3 51. A conveying groove is opened on the top of the fixed block 3 51. The inner wall of the conveying groove is rotatably connected with a toothed conveyor belt 511 through a rotating shaft. The bottom of the toothed conveyor belt 511 is meshed and connected with the top of the auger 311. A connecting block 52 is fixedly connected to the right side of the fixed block 3 51.

[0025] The back of the connecting block 52 is rotatably connected to a rotating rod 521 through a pin shaft. There are two rotating rods 521, which are symmetrically arranged with the connecting block 52 as the center. The front of the rotating rod 521 located at the back is rotatably connected to a conveying auxiliary wheel 522. The pipe connected by hot melt is placed on the toothed conveyor belt 511. Since the conveying auxiliary wheel 522 is affected by gravity, the rotating rod 521 drives it to rotate so that it is level with the toothed conveyor belt 511. Then, the auger 311 is rotated under the start of the motor 31. Since the toothed conveyor belt 511 and the auger 311 are aligned with each other, the conveyor belt 511 and the conveyor belt 511 are connected to each other. 311 is a meshing connection, which will cause the toothed conveyor belt 511 to move, driving the pipeline to move, and the conveying auxiliary wheel 522 can also assist in transportation. At the same time, the rotating roller 63 will also shrink when the rotating rod 521 rotates, avoiding affecting the moving pipeline. The pipeline that has been transported will then contact the spring auxiliary roller 121 and the clamping auxiliary wheel 13. Compared with the previous manual assembly, the automatically transported pipeline can not only simplify the assembly process, but also make the assembly faster, avoiding the problem of slow assembly and gradual hardening of the curled edge of the inner wall of the pipeline after hot-melt connection.

[0026] An auxiliary rotating assembly 6 is arranged on the front of the rotating rod 521, and the auxiliary rotating assembly 6 includes a rotating block 61. The back of the rotating block 61 is rotatably connected to the front of the rotating rod 521 through a pin shaft. A moving rod 2 611 is fixedly connected to the left side of the rotating block 61. A limiting block 1 612 is fixedly connected to the back of the moving rod 2 611. The back of the limiting block 1 612 contacts the limiting block 2 632. A rotating roller 63 is fixedly connected to the back of the limiting block 2 632.

[0027] The back side of the rotating roller 63 near the limit block 2 632 is fixedly connected with a spring telescopic cylinder 3 631, and the front side of the rotating rod 521 located at the front is rotatably connected with the spring telescopic cylinder 2 62. A mounting groove is provided on the right side of the fixed block 3 51, and the inner wall of the mounting groove is fixedly connected with the side of the spring telescopic cylinder 2 62 away from the rotating rod 521. When the tail of the pipeline leaves the conveying auxiliary wheel 522, the rotating rod 521 can be reset under the action of the spring telescopic cylinder 2 62 to return to its original state, and the movement of the rotating rod 521 is The rotating block 61 will drive the moving rod 2 611 to move, and the movement of the moving rod 2 611 will cause the limit block 1 612 to lift the limit block 2 632, so that the rotating roller 63 moves toward the pipeline direction. At the same time, the spring telescopic cylinder 3 631 will also be deformed under the movement of the limit block 1 612. The contact between the rotating roller 63 and the pipeline will assist the rotation of the pipeline, avoiding a large speed difference between the two sections of the pipe, cracking at the hot melt connection, and also avoiding the problem of bending of the pipeline when cooling.

[0028] A specific application of this embodiment is: before using the device, first connect the two water pipes to the water inlet pipe 32 and the one-way valve 351 respectively, then place the pipe connected by hot melt on the toothed conveyor belt 511, and because the conveying auxiliary wheel 522 is affected by gravity, the rotating rod 521 drives it to rotate so that it is level with the toothed conveyor belt 511, and then the auger 311 is rotated under the start of the motor 31. Since the toothed conveyor belt 511 and the auger 311 are meshed and connected, the toothed conveyor belt 511 will move, driving the pipe to move. Movement, the conveying auxiliary wheel 522 can also assist in transportation, and at the same time, the rotating roller 63 will shrink when the rotating rod 521 rotates, so as to avoid affecting the moving pipe. Then, the pipe completed by conveying will contact with the spring auxiliary roller 121 and the clamping auxiliary wheel 13. Compared with the previous manual assembly, the automatically conveyed pipe can not only simplify the assembly process, but also make the assembly faster, avoiding the problem of slow assembly and gradual hardening of the curling edge of the inner wall of the pipe after hot-melt connection. The setting of several spring auxiliary wheels 21 can also assist in smoothing.

[0029] When the tail of the pipeline leaves the auxiliary conveying wheel 522, the rotating rod 521 can be reset to its original state under the action of the spring telescopic cylinder 2 62. The movement of the rotating rod 521 will cause the rotating block 61 to drive the moving rod 2 611 to move. The movement of the moving rod 2 611 will cause the limit block 1 612 to lift the limit block 2 632, so that the rotating roller 63 moves toward the pipeline direction. At the same time, the spring telescopic cylinder 3 631 will also be deformed under the movement of the limit block 1 612. The setting of the spring telescopic cylinder 3 631 makes it easier to reset the rotating roller 63. The contact between the rotating roller 63 and the pipeline will assist the rotation of the pipeline, thereby avoiding a large speed difference between the two sections of the pipe and cracking at the hot-melt connection. At the same time, it also avoids the problem of bending of the pipeline when it is cooled.

[0030] When the pipeline is moving, the rotating plate 421 will enter the pipeline. Since the outer side of the rotating plate 421 is larger than the inner diameter of the pipeline, the rotating plate 421 will rotate when entering the pipeline, so that the rotating plate 421 fits against the inner wall of the pipeline. The fitted rotating plate 421 will cause the two spring telescopic cylinders 42 to rotate around the limit column 411 during the continuous movement of the pipeline. The continuous rotation of the spring telescopic cylinder 42 will transport the liquid in the hydraulic cylinder 43 to the hydraulic cylinder 44. Due to the increase in the volume of the liquid in the hydraulic cylinder 44, the two smoothing plates 441 will move outward and contact the curling edge of the inner wall of the pipeline to smooth it, so as to avoid the curling edge from cooling without being smoothed, thereby causing the inner diameter of the pipeline to become smaller in subsequent use, and a funnel-shaped water plug may be formed at the curling edge, which will cause the flow rate of water in the pipeline to decrease, increase the water flow resistance, and enable the pipeline to be used normally after hot-melt connection.

[0031] The auger 311 is rotated by starting the motor 31. The rotation of the auger 311 causes the pulley 312 and the belt 313 to drive the water inlet pipe 32 to rotate. The water in the water inlet pipe 32 is sprayed out from the water outlet nozzle 323 through the water delivery pipe 322, so as to cool the inner wall of the pipe after the hot-melt connection is smoothed. The rotation of the pipe driven by the device will also cause the water inside the pipe to evenly cool the inside of the pipe. At the same time, the rotation of the auger 311 will cause the toothed belt 33 to move, and the movement of the toothed belt 33 will drive the rotary The moving wheel 331 moves synchronously. The movement of the rotating wheel 331 causes the rotating column 332 to drive the moving rod 34 to reciprocate. When the moving rod 34 pushes the water tank 35, the water in the water tank 35 is squeezed and sprayed out from the annular nozzle 352 to cool the hot melt connection on the outer surface of the pipeline, so that the inner and outer walls of the pipeline are cooled at the same time. Compared with the previous single outer wall cooling, the simultaneous cooling of the inner and outer walls makes the cooling efficiency of the inner and outer walls the same, thereby avoiding bending or even cracking of pipelines with different cooling efficiencies.
