Description

Technical Field

[0001] The invention relates to the field of pipeline alignment, in particular to a PE pipeline alignment circle clamping device. Background Art

[0002] During the construction of existing PE pipes, the ends of the two pipes need to be fixed. Depending on actual needs, it is sometimes necessary to fuse and seal the pipe joints, and add three-way or four-way pipes at the joints to meet construction requirements.

[0003] However, the pipes need to be clamped when connected, and the clamped pipes need to be aligned. However, due to the large mass of the pipes when clamped, the pipes can easily slide relative to the clamping device. Sometimes the pipes are heavy and the soil on the construction site is slippery, and the pipes will drive the bracket to move, affecting the construction accuracy. The pipes also need to be heated after clamping. Since the pipes are round, the installation process of the heating equipment on the outer pipe and the pipe is more troublesome, and relative movement may occur between the casing and the pipe during the heating process. After the heating equipment is installed, the outer pipe and the pipe cannot be heated and positioned. When relative movement occurs between the outer pipe and the pipe, the heating efficiency of the casing and the pipe is low, affecting the construction. Summary of the invention

[0032] The fastening mechanism 2 is provided to clamp the pipes that need to be aligned. While the fastening mechanism 2 fixes the pipes, the fastening mechanism 2 will push the stabilizing mechanism 6 provided inside the bracket 1 into the soil through the connecting mechanism 5, so that the bracket 1 is stabilized on the construction site; the sleeve can be clamped on the surface of the pipe by the clamping mechanism 3, and while the clamping mechanism 3 is fastening, the heating mechanism 4 is combined and energized to heat the sleeve and the pipe. Since steel wire is provided inside the pipe, the heating mechanism 4 can heat the sleeve and the pipe to a hot-melt state and squeeze them together, thereby realizing the connection between the sleeve and the pipe and improving the fusion efficiency of the pipe.

[0033] The clamping mechanism 3 includes a lower support plate 24 with an opening facing upward, which is arranged on the bracket 1; an upper support plate 25 with an opening facing downward is arranged above the lower support plate 24; the upper support plate 25 and the lower support plate 24 are engaged with each other; inner washers 26 are arranged on the upper support plate 25 and the lower support plate 24; upper connecting plates 22 are arranged on both side walls of the upper support plate 25; lower connecting plates 23 corresponding to the upper connecting plates 22 are arranged on both side walls of the lower support plate 24; the upper connecting plate 22 and the lower connecting plate 23 are connected by fastening bolts 21.

[0034] Align the pipes that need to be fastened, and put the outer pipe on the connection of the two pipes. The outer pipe can be a two-way pipe, a three-way pipe or a four-way pipe. The pipes that need to be connected can be fastened by the upper support plate 25 and the lower support plate 24, so that the outer diameter of the pipe is fixed. The upper connecting plate and the lower connecting plate are interlocked with each other, and the fastening bolt 21 passes through the upper connecting plate and the lower connecting plate, and then the fastening bolt 21 is tightened. Since the fastening bolt 21 and the upper connecting plate and the lower connecting plate are threadedly matched, the upper support plate 25 and the lower support plate 24 will be clamped when the fastening bolt 21 is tightened, thereby fastening the two pipes and aligning the two pipes with each other.

[0035] The clamping mechanism 3 includes two support rods 33 connected to two brackets 1, and a stabilizing ring 32 and a rotating ring are connected to the support rod 33. A movable ring 31 is rotatably connected to the stabilizing ring 32. A plurality of clamping assemblies 37 are provided on the stabilizing ring 32 and the movable ring 31. The plurality of clamping assemblies 37 are used to clamp the outer sleeve on the outer wall of the pipeline. The stabilizing ring 32 and the movable ring 31 are both provided with a locking assembly 34. The locking assembly 34 is used to close and lock the stabilizing ring 32 and the movable ring 31. An adjusting assembly 30 is provided at the connection between the stabilizing ring 32 and the movable ring 31. The adjusting assembly 30 is used to adjust The unfolding angle between the stabilizing ring 32 and the movable ring 31 is adjusted, and guide grooves 374 are provided inside the movable ring 31 and the stabilizing ring 32, and guide plates 310 corresponding to the guide grooves 374 are provided inside the guide grooves 374, and the guide plates 310 slide inside the guide grooves 374; an opening groove 38 is provided on the stabilizing ring 32, and a plurality of second buckles 39 are provided on the outer wall of the guide plate 310, and a gear 35 meshing with the second buckle 39 is provided on one side of the second buckle 39, and the gear 35 is connected to the motor, and the motor is arranged inside the sleeve 36, and the sleeve 36 is slidably arranged on the bracket 1 for adjusting the position of the motor.

[0036] The clamping assembly 37 includes a clamping block 371 slidably arranged on the movable ring 31 and the stabilizing ring 32, a slide plate 372 is arranged at the end of the clamping block 371, and a guide column 373 is arranged on the slide plate 372; a guide groove 374 is provided on the guide plate 310 for the guide column 373 to pass through, and the guide groove 374 is moved to squeeze the guide column 373, and the guide column 373 moves close to or away from the center of the pipe; a slider 375 is provided on the outer wall of the guide plate 310, and an inner groove 311 is provided on the movable ring 31 and the stabilizing ring 32, and a slide groove 376 connected thereto is provided on the inner groove 311, and the slider 375 slides inside the slide groove 376.

[0037] The locking assembly 34 includes a buckle plate 347 arranged on the guide plate 310, and a first buckle 346 is arranged on the movable ring 31 and the stabilizing ring 32. The first buckle 346 and the buckle plate 347 are buckled together. A pull rod 342 is arranged on the first buckle 346, and a pull buckle 341 is arranged on the top of the pull rod 342. An elastic member 344 is sleeved on the pull rod 342, and the elastic member 344 is used to push the first buckle 346 to reset.

[0038] The adjustment assembly 30 includes a first connecting ring 301 arranged on the end of the movable ring 31, and a second connecting ring 303 is arranged at the end of the stabilizing ring 32. The first connecting ring 301 and the second connecting ring 303 cooperate with each other. An outwardly protruding plug plate 302 is arranged at the end of the movable ring 31, and an inwardly recessed card slot 304 is arranged at the end of the stabilizing ring 32. The plug plate 302 and the card slot 304 are plugged into each other.

[0039] The first connecting ring 301 and the second connecting ring 303 are arranged at intervals, and the first connecting ring 301 and the second connecting ring 303 are sleeved on the support rod 33, the first connecting ring 301 can rotate around the support rod 33, and the second connecting ring 303 can move on the support rod 33 along the direction of the support rod 33. Since the first connecting ring 301 and the second connecting ring 303 can rotate relative to each other, it is convenient for the pipeline to enter between the first connecting ring 301 and the second connecting ring 303, and the outer tube sleeved on the pipeline is clamped by the first connecting ring 301 and the second connecting ring 303; when the pipeline is clamped, the heating mechanism 4 circuit is connected, and then the power of the heating mechanism 4 is turned on, and the heating mechanism 4 can heat the steel wire inside the pipeline, thereby achieving the effect of melting the pipeline and allowing the two pipeline walls to fuse together. When the first connecting ring 301 and the second connecting ring 303 are sleeved on the pipe, since the radius size of the first connecting ring 301 and the second connecting ring 303 is larger than the radius size of the upper support plate 25 and the lower support plate 24, when the two first connecting rings 301 and the second connecting rings 303 are closed, at this time, the sleeve and the inner pipe are not fixed, and the sleeve is slid on the pipe, and the position of the sleeve on the pipe is adjusted so that the sleeve is located in the middle of the connection between the two pipe ends; in order to adapt to the heating mechanism 4 to ensure that the connection of the two-way pipe, the three-way pipe or the four-way pipe is heated during heating, it is necessary to adjust the heating position of the heating mechanism 4 at the pipe connection. When the spacing between the two sleeve shells 36 is adjusted, the position of the heating mechanism 4 on the support rod 33 can be adjusted to ensure that the motor can always engage with the second buckle 39; then start the two motors, the two motors are synchronous motors, and the rotation of the two motors drives the gear 35 to rotate The gear 35 rotates to drive the second buckle 39 to rotate, and the second buckle 39 drives the guide plate 310 to rotate. The guide plate 310 rotates inside the inner groove 311. When the guide plate 310 rotates, the guide plate 310 drives the guide groove 374 inside it to rotate. The guide groove 374 is an arc-shaped structure. The guide groove 374 rotates to push the clamping block 371 set inside it to move until the clamping block 371 can only move along the center direction of the pipe under the limiting action of the first connecting ring 301 and the second connecting ring 303. Therefore, when the guide groove 374 rotates, it will push the clamping block 371 to clamp on the outer wall of the sleeve. When the clamping is stable, the motor stops rotating, so that the two guide plates 310 are fixed. Here, the driving gear 35 rotates to achieve the fixing of the second buckle 39. Bolt fastening or other fastening methods can be used. It is not limited to the method of only using the motor to limit the rotation of the gear 35.When the guide plate 310 rotates, the buckle plate 347 arranged on it will be driven to move. During the movement of the buckle plate 347, the bottom of the first buckle 346 will be squeezed. The cross-sections of the first buckle 346 and the buckle plate 347 are both inclined surfaces. When the buckle plate 347 slides over the bottom of the first buckle 346, the buckle plate 347 squeezes the first buckle 346, and the first buckle 346 is stored in the groove 345 matched with the first buckle plate 347. The first buckle 346 squeezes the elastic member 344 and compresses the elastic member 344. When the buckle plate 347 slides under the first buckle 346, the elastic member 344 pushes the first buckle 346 to reset, and the first buckle 346 is locked. On one side of the buckle plate 347, the first buckle 346 limits the buckle plate 347 so that the buckle plate 347 does not move. When the first buckle 346 needs to be removed, the pull buckle 341 is pulled to move the pull rod 342 upward from the inside of the through hole 343; when the guide plate 310 is pushed by the second buckle 39, the guide plate 310 will push the other guide plate 310 to move, so that the two guide plates 310 are located inside the first connecting ring 301 and the second connecting ring 303. When the gear 35 is fixed and does not rotate, the first connecting ring 301 and the second connecting ring 303 are locked, so that the clamping block 371 can be stably clamped on the pipe.

[0040] The heating mechanism 4 includes a first heating plate 41 arranged on the movable ring 31 and a second heating plate 42 arranged on the stabilizing ring 32. The first heating plate 41 and the second heating plate 42 are provided with a spirally wound conductive ring 45 inside. A clamping plate 43 is provided at one end of the conductive ring 45, and a stop block 44 is provided at the other end. The clamping plate 43 and the stop block 44 are in contact with each other. When the movable ring 31 and the stabilizing ring 32 are closed, the clamping plate 43 and the stop block 44 are electrically connected. When the movable ring 31 and the stabilizing ring 32 are separated, the clamping plate 43 and the stop block 44 are separated.

[0041] When the first heating plate 41 and the second heating plate 42 are fitted together, since the clamping plate 43 is a structure of an elastic expansion plate with a certain elasticity, it will be pressed against the end of the stop block 44, so that the multiple conductive circles 45 form a closed ring loop. When an appropriate current is passed through the conductive circle 45, inductive heating will be generated, which will directly heat the pipe containing the steel wire inside, causing the pipe to melt. Under the action of the clamping block 371, the pipe can be better fitted after the heat melting.

[0042] The stabilizing mechanism 6 includes a stabilizing rod 61 arranged on the bracket 1. A through groove 63 is arranged inside the bracket 1. The stabilizing rod 61 passes through the through groove 63 and is inserted into the soil. An internal thread 67 is arranged in the through groove 63. An external thread 62 is arranged on the upper outer circumference of the stabilizing rod 61. The external thread 62 and the internal thread 67 are spirally matched. A spiral plate 65 is arranged on the stabilizing rod 61, and a mud discharge hole 64 is opened on the side wall of the bracket 1.

[0043] The connecting mechanism 5 includes an insertion rod 51 arranged on the fastening bolt 21, a rotating block 52 is arranged on the outer circumference of the insertion rod 51, a slot 54 is opened on the top of the stabilizing rod 61, a driven block 53 is arranged on the inner wall of the slot 54, the insertion rod 51 is plugged into and matched with the slot 54, and the rotating block 52 drives the driven block 53 to rotate synchronously.

[0044] When the fastening bolt 21 is screwed, the fastening bolt 21 drives the insertion rod 51 to rotate, and the rotating block 52 on the insertion rod 51 drives the matched driven block 53 to rotate, and the rotation of the driven block 53 will drive the stabilizing rod 61 to rotate synchronously. When the stabilizing rod 61 rotates, it rotates downward through the cooperation of the set internal thread 67 and the external thread 62. The stabilizing rod 61 rotates downward and moves downward from the inside of the through groove 63. The stabilizing rod 61 drives the spiral plate 65 to enter the inside of the soil. When the spiral plate 65 moves downward, the soil is discharged upward from the inside of the mud discharge hole 64, so that the spiral plate 65 is stabilized inside the soil. Since the stabilizing plate is set on the stabilizing rod 61, the stabilizing rod 61 can play the role of stabilizing the bracket 1, so that when the pipeline is docked, the bracket 1 will not move on the soil.

[0045] When the present invention is in use, the pipes to be fastened are aligned, and the outer pipe is sleeved at the connection of the two pipes. The outer pipe can be a two-way pipe, a three-way pipe or a four-way pipe. The pipes to be connected can be fastened by the upper support plate 25 and the lower support plate 24, so that the outer diameter of the pipe is fixed. The fastening bolt 21 passes through the upper connecting plate and the lower connecting plate through the mutual engagement between the upper connecting plate and the lower connecting plate, and then the fastening bolt 21 is tightened. Since the fastening bolt 21 and the upper connecting plate and the lower connecting plate are threadedly matched, the upper support plate 25 and the lower support plate 24 will be clamped when the fastening bolt 21 is tightened, so as to fasten the two pipes and align the two pipes with each other; when the fastening bolt 21 drives the insertion rod 51 to rotate The rotating block 52 on the insertion rod 51 drives the matched driven block 53 to rotate, and the rotation of the driven block 53 drives the stabilizing rod 61 to rotate synchronously. When the stabilizing rod 61 rotates, it rotates downward through the cooperation of the set internal thread 67 and the external thread 62. The stabilizing rod 61 rotates downward and moves downward from the inside of the through groove 63. The stabilizing rod 61 drives the spiral plate 65 to enter the inside of the soil. When the spiral plate 65 moves downward, the soil is discharged upward from the inside of the mud discharge hole 64, so that the spiral plate 65 is stabilized inside the soil. Since the stabilizing plate is set on the stabilizing rod 61, the stabilizing rod 61 can play a role in stabilizing the bracket 1, so that when the pipeline is docked, the bracket 1 will not move on the soil. Then the first connecting ring 301 and the second connecting ring 303 are used to clamp the outer tube sleeved on the pipeline; when the outer tube and the pipeline are clamped by the clamping block 371, the circuit of the heating mechanism 4 is connected, and then the power of the heating mechanism 4 is turned on. The heating mechanism 4 can heat the steel wire inside the pipeline, thereby melting the pipeline and allowing the two pipeline walls to fuse together. After the heating is completed, the first connecting ring 301 is unfolded from the second connecting ring 303, and the upper support plate 25 and the lower support plate 24 are separated.
