Description

Technical Field

[0001] The present application relates to the technical field of limit devices, and more specifically, to a pipeline limit device and a use method thereof. Background Art

[0002] Water and gas are an indispensable part of our lives. The transmission of these objects depends on pipelines, so the installation of pipelines is an important step to ensure a healthy and safe life; especially during the original distance transportation process, the pipeline needs to be erected to ensure the long-term safe operation of the pipeline.

[0003] In the related art, when an outdoor pressure pipeline is suspended, it is necessary to pre-embed the bracket in the reverse direction of the pipeline laying in advance, and then connect and assemble the pipeline and the bracket, but it is not convenient to connect the pipeline connection component to the pre-embedded bracket during assembly; in order to make the pipeline installation more convenient, for example, the document with the prior art publication number CN113374939B provides an outdoor thermal pipeline bracket limit device, which aligns the card block with the guide groove on the limit block. When pressing down, the inclined surface of the card block is squeezed by the limit block, and the card block moves toward the inside of the deep groove. Continue to press down. When the card block drops to the horizontal plane of the slide groove, the card block enters the slide groove under the action of the micro spring. At this time, the guide bracket no longer moves in the vertical direction. At this time, the guide bracket can be connected to the pre-embedded bracket by screws.

[0004] Although the above-mentioned prior art solution can achieve the effect of vertically installing the guide bracket by pushing the card block through the spring, the top of the guide bracket is in a fixed state. When the embedded bracket deviates, the pipe located on the top of the guide bracket cannot be connected normally, and it is not convenient to move and adjust the height of the placed pipe, which brings inconvenience to various fine-tuning operations in actual work.

[0005] In view of this, we propose a pipeline limiting device and a use method. Summary of the invention

[0008] 2. Technical solution

[0009] The present application provides a pipeline limiting device, comprising:

[0010] A pipe support, wherein arc-shaped grooves for supporting the pipe are provided on both sides of the top of the pipe support, a box body is fixedly provided at the bottom of the pipe support, and an annular seat is fixedly provided at the bottom of the box body;

[0011] A bearing seat, the bearing seat is slidably arranged on the inner side of the pipe support, and rollers are symmetrically arranged on both sides of the bearing seat near the arc groove;

[0012] A limit plate, the limit plate is symmetrically slidably arranged on the inner side of the pipeline support, and the limit plate is located between the two symmetrically arranged rollers;

[0013] A hand plate, the hand plate is rotatably arranged on the outside of the box body, and the hand plate synchronously drives the bearing seat and the limit plate to operate when the hand plate rotates continuously;

[0014] A disc, the disc is located inside the annular seat, and the disc rises and falls under the drive of the hand disc;

[0015] A base, wherein a bearing groove is provided on the inner side of the base, and a disc is rotatably arranged on the inner side of the bearing groove;

[0016] An inserting plate, the inserting plate is slidably arranged inside the base, and the inserting plate moves toward the outside of the base under the driving of the hand plate;

[0017] The embedded seat is located on the outside of the base, and a slot is provided on the inside of the embedded seat corresponding to the plug board.

[0018] By adopting the above technical solution, the base is placed on the inner side of the embedded seat, and then the pipe is placed on the top of the pipe support. At this time, the rollers on both sides of the bearing seat are located on the top of the pipe support, and the limit plate between the rollers is away from the pipe. The direction of the pipe support is adjusted according to the connection direction of the pipe. When adjusting, the box is directly rotated to make the box drive the disc to rotate on the inner side of the base, and then the pipe is pushed axially according to the connection distance of the pipe, so that the pipe moves through the rollers to facilitate the connection of two adjacent pipes, and then the hand plate is continuously rotated to drive the bearing seat to move downward, and at the same time the limit plate slowly approaches the pipe. When the roller is located inside the pipe support, the pipe is supported through the arc groove. At this time, according to the laying height of the pipe The height of the arc groove can be adjusted by degrees. During adjustment, the box can be driven to rise and fall on the top of the disc by reciprocating the hand plate. Due to the reciprocating rotation of the hand plate, when the hand plate synchronously drives the bearing seat and the limit plate to move, the bearing seat and the limit plate can be reciprocated to prevent the bearing seat and the limit plate from being continuously driven and displaced. When the hand plate stops reciprocating, the bearing seat and the limit plate are located at the position before adjustment. After the height is adjusted, the hand plate is continuously rotated to drive the limit plate to continue to clamp the pipe. At the same time, the hand plate drives the plug plate inside the base to move outward. When the limit plate clamps the pipe, the hand plate cannot be rotated. At this time, one end of the plug plate is inserted into the inner side of the embedded seat for locking, so as to automatically connect the base and the embedded seat.

[0019] As an optional solution to the technical solution of the present application document, a support plate is fixedly provided at the bottom of the bearing seat, and a screw A is threadedly provided on the inner side of the support plate.

[0020] By adopting the above technical solution, when the screw rod A rotates, the screw rod A drives the outer support plate to rise and fall, so that the support plate drives the roller to rise and fall on the inner side of the pipe support, and the roller is stored in the inside of the box through the support plate. At the same time, the screw rod A drives the limit plate to clamp the pipe by driving the clamping assembly.

[0021] As an optional solution to the technical solution of the present application document, the clamping assembly includes a worm, which is fixedly arranged on the top of the screw A, a bearing frame is rotatably arranged on the bottom of the worm, a worm wheel is symmetrically meshedly arranged on the outer side of the worm, the worm wheel is rotatably arranged on the inner side of the bearing frame, a screw B is fixedly arranged on the inner side of the worm wheel, the screw B is rotatably arranged inside the pipe support, the screw B is threadedly arranged on the bottom of the limit plate, the limit plates are approached to each other under the drive of the screw B, and a gasket is fixedly arranged on the side where the limit plates are close to each other.

[0022] By adopting the above technical solution, the worm is driven to rotate by the screw A, so that the worm drives the outer worm wheel to rotate at the same time, and the worm wheel drives the inner screw B to rotate. The limit plates are driven by the screw B to approach each other to clamp the pipeline. When the arc groove supports a pipeline with a smaller diameter, the arc groove supports the pipeline more stably.

[0023] As an optional solution to the technical solution of the present application document, the screw rod A rotates under the drive of the hand plate, a connecting shaft is fixedly arranged on the inner side of the hand plate, the connecting shaft is rotatably arranged on one side of the box body, a driving bevel gear is fixedly arranged on one end of the connecting shaft located inside the box body, a driven bevel gear is meshed with the bottom of the driving bevel gear, a gear A is fixedly arranged on the bottom of the driven bevel gear, the gear A is rotatably arranged at the bottom of the box body, a gear B is meshed with the outer side of the gear A, and the gear B is fixedly arranged on the outer side of the screw rod A.

[0024] By adopting the above technical solution, the connecting shaft is driven to rotate by the hand plate, so that the connecting shaft drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear to rotate, so that the driven bevel gear drives the bottom gear A to rotate, and the gear A drives the gear B outside the screw rod A to rotate, so that the hand plate drives the screw rod A to rotate and drive the bearing seat to rise and fall.

[0025] As an optional scheme of the technical scheme of the present application document, a shaft sleeve is rotatably provided on the outer side of the connecting shaft, and the shaft sleeve is rotatably provided on one side of the box body, and a gear C is fixedly provided on one end of the shaft sleeve located on the outer side of the box body, and a connecting plate is rotatably provided on the side of the hand plate close to the gear C, and a tooth block is fixedly provided on the other end of the connecting plate, and the tooth block is engaged with the outer side of the gear C, and a handle is fixedly provided on the outer side of the hand plate corresponding to the rotating end of the connecting plate, and a latch is inserted into the inner side of the handle, and a pin hole is opened on the side of the connecting plate close to the hand plate, and when the connecting plate is parallel to the handle, the pin hole and the latch are coaxial, and the hand plate drives the gear C to rotate through the connecting plate, and when the gear C rotates, it drives the box to rise and fall on the top of the disc.

[0026] By adopting the above technical scheme, when the hand plate rotates continuously, the bearing seat, the limit plate and the plug plate can be driven to move at the same time. At this time, the handle on the outside of the hand plate is engaged with the connecting plate through the latch, and the hand plate rotates on the outside of the box body through the connecting shaft, and the bearing seat, the limit plate and the plug plate are driven to move through the connecting shaft. When the hand plate rotates back and forth, the latch is pulled out from the inside of the pin hole, and the connecting plate is rotated to one side of the handle, so that the tooth block at the other end of the connecting plate is automatically stuck on the outside of the gear C. When the hand plate is rotated, the gear C is pulled to rotate through the connecting plate. When the gear C rotates a certain angle, the hand plate is directly reversed so that the connecting plate pushes the tooth block to move toward the origin and engages with the gear C again. At this time, the gear C rotates in the same direction to drive the box body to rise and fall, and the hand plate drives the connecting shaft back to the origin to drive the bearing seat and the limit plate to reset, and so on. The adjustment work of the device is completed by controlling the different rotations of the hand plate.

[0027] As an optional solution to the technical solution of the present application document, tooth plates are symmetrically fixed on the top of the disc, spiral tooth plates are meshed on the outer sides of the tooth plates, gears D are fixed on the outer sides of the spiral tooth plates, gears E are meshed between two adjacent gears D on one side, and gears E are fixed at the other end of the shaft sleeve. When the hand plate drives the gears E to rotate, it simultaneously drives the plug plate at the bottom of the disc to move.

[0028] By adopting the above technical solution, when the hand plate drives gear C to rotate, gear C drives gear E to rotate, and gear E simultaneously drives the outer gear D to rotate, so that gear D drives the spiral toothed disc on one side to rotate, and the spiral toothed disc drives the toothed plate to rise and fall. When the spiral toothed disc stops rotating, the toothed plate generates vertical pressure on the spiral toothed disc. At this time, the spiral toothed disc will not rotate under force, and thus has a self-locking effect, so that the box body remains stable directly after being raised or lowered.

[0029] As an optional solution to the technical solution of the present application document, two plug plates are symmetrically arranged, and the plug plates are slidably arranged at the bottom of the base through guide rails. A gear F is meshed between the two plug plates, and a sliding hole is provided on the outer side of the base corresponding to the plug plates. The plug plates are driven by the gear F and pass through the sliding hole to be inserted into the inner side of the slot. The slot is provided on the inner side of the embedded seat, and a transmission shaft is fixedly arranged on the top of the gear F, and a transmission block is fixedly arranged on the top of the transmission shaft. The transmission block is rotatably arranged at the bottom of the disc, and a telescopic shaft A is fixedly arranged on the top of the transmission block, and the telescopic shaft A is slidably arranged on the inner side of the screw rod A.

[0030] By adopting the above technical solution, when the screw rod A rotates, it drives the internal telescopic shaft A to rotate, so that the telescopic shaft A drives the transmission block at the bottom of the disc to rotate, and the transmission block drives the transmission shaft to rotate, so that the transmission shaft drives the gear F to rotate, and the gear F drives the plug plate to be inserted into the inner side of the slot along the guide rail, and the base and the embedded seat are locked by the plug plate.

[0031] As an optional solution to the technical solution of the present application document, bolts are evenly distributed on the top of the embedded seat, and the bolts are located on the inner side of the arc-shaped waist hole, and the arc-shaped waist hole is opened on the outer side of the annular seat, and a bottom nut is fixedly provided at the bottom of the annular seat on the outer side of the bolt, and a top nut is fixedly provided at the top of the annular seat.

[0032] By adopting the above technical scheme, when the base is placed inside the embedded seat, the bolts are inserted into the inner side of the arc-shaped waist hole. When the pipe support is fine-tuning the angle, the pipe support drives the annular seat to rotate. At this time, the arc-shaped waist hole rotates with the bolt, and when the pipe support adjusts the height, the annular seat moves up and down on the outside of the bolt. After the height and angle of the pipe support are adjusted, the base is fixed to the embedded seat. At this time, the bottom nut on the outside of the bolt is rotated to approach the bottom of the annular seat, and the annular seat is supported by the bottom nut, and then the top nut is tightened to the top of the arc-shaped waist hole. Under the action of the bottom nut and the top nut, the force of the pipe support is directly transferred to the top of the embedded seat, and the box body is fixed to prevent the box body from rotating at will on the top of the disc.

[0033] The present application provides a method for using the above pipeline limiting device, comprising the following steps:

[0034] S1. Place the base inside the embedded seat, and then place the pipe on the top of the pipe support. At this time, the rollers on both sides of the bearing seat are located on the top of the pipe support, and the limit plate between the rollers is away from the pipe;

[0035] S2. Adjust the direction of the pipe support according to the connection direction of the pipe. When adjusting, directly rotate the box so that the box drives the disc to rotate on the inner side of the base;

[0036] S3, axially pushing the pipeline according to the connection distance of the pipeline, so that the pipeline moves through the roller, so as to connect two adjacent pipelines;

[0037] S4. Continuously rotate the hand plate to drive the bearing seat to move downward, and at the same time, the limit plate slowly approaches the pipe. When the roller is located inside the pipe support, the pipe is supported through the arc groove.

[0038] S5. At this time, the box body is driven to rise and fall on the top of the disc by reciprocating the hand plate, so as to adjust the height of the arc groove according to the laying height of the pipeline. As the hand plate reciprocates, when the hand plate synchronously drives the bearing seat and the limit plate to move, the bearing seat and the limit plate can be reciprocated to prevent the bearing seat and the limit plate from being displaced due to continuous driving;

[0039] S6. After the height is adjusted, the hand plate is rotated continuously to make the hand plate drive the limit plate to continue to clamp the pipe. At the same time, the hand plate drives the plug plate inside the base to move outward. When the limit plate clamps the pipe, the hand plate cannot be rotated. At this time, one end of the plug plate is inserted into the inner side of the embedded seat for locking, so as to automatically connect the base and the embedded seat.

[0040] S7. Finally, fix the annular seat by the bottom nut and the top nut on the outside of the bolt.

[0043] (1) The present application uses a hand plate to drive the box to adjust the height of the pipe support, and a roller is arranged on the inner side of the pipe support to facilitate the movement of the pipe. Therefore, it effectively solves the problem that when the embedded bracket deviates, the pipe located on the top of the guide bracket cannot be connected normally, and it is inconvenient to move and adjust the height of the placed pipe, which brings inconvenience to various fine-tuning operations in actual work. Furthermore, when the embedded seat deviates, the embedded seat and the base are locked, the height of the pipe support can be adjusted by the hand plate, and the direction of the pipe can be adjusted by rotating the pipe support. At the same time, the roller facilitates the movement of the pipe and the connection, which brings many conveniences to the fine-tuning work during pipeline installation.

[0044] (2) The present application sets a limit plate on the inner side of the pipe support. The limit plate is driven by the hand plate to clamp the pipe. At the same time, the hand plate drives the roller to move downward to release the support for the pipe. The two are synchronously linked to fix the pipe on the inner side of the arc groove.

[0045] (3) The present application sets a plug plate inside the base. When the hand lever drives the limit plate to move, the plug plate is simultaneously driven to move inside the base, so that the plug plate is inserted into the inner side of the embedded seat, so that the base and the embedded seat are automatically locked when the pipeline is fixed.

[0046] (4) The present application provides a hand lever on the outside of the box body, and the device can be driven differently by controlling the different rotation modes of the hand lever, making the device more convenient to operate during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] The present application is further described in detail below in conjunction with the accompanying drawings.

A limiting plate 3 for clamping the pipeline is symmetrically provided between the symmetrically provided rollers 21 on the inner side of the pipeline support 1, and a box body 12 is fixedly provided on the bottom of the pipeline support 1, and a roller 21 for clamping the pipeline is symmetrically provided on the outer side of the box body 12. The hand plate 4 drives the bearing seat 2 to descend, and at the same time, the hand plate 4 drives the limit plate 3 to clamp the pipe. An annular seat 13 is fixedly provided at the bottom of the box body 12, and a disc 5 is provided inside the annular seat 13. The disc 5 is rotatably provided on the inner side of the bearing groove 61, and the bearing groove 61 is opened on the inner side of the base 6. The box body 12 rises and falls on the top of the base 6 when the hand plate 4 reciprocates, and the hand plate 4 continuously rotates, driving the plug plate 7 inside the base 6 to engage with the embedded seat 8, and the base 6 is engaged with the inner side of the embedded seat 8 through the plug plate 7.

[0057] During installation, place the base 6 on the inner side of the embedded seat 8, and then place the pipe on the top of the pipe support 1. At this time, the rollers 21 on both sides of the bearing seat 2 are located on the top of the pipe support 1, and the limit plate 3 between the rollers 21 is away from the pipe. The direction of the pipe support 1 is adjusted according to the connection direction of the pipe. When adjusting, directly rotate the box 12 to make the box 12 drive the disc 5 to rotate on the inner side of the base 6, and then push the pipe axially according to the connection distance of the pipe, so that the pipe moves through the roller 21 to facilitate the connection of two adjacent pipes, and then continuously rotate the hand plate 4 to drive the bearing seat 2 to move downward, and at the same time, the limit plate 3 slowly approaches the pipe. When the roller 21 is located inside the pipe support 1, the pipe is supported through the arc groove 11. At this time, the arc groove 11 is adjusted according to the laying height of the pipe. The height of the groove 11 can be adjusted. During adjustment, the box 12 can be driven to rise and fall on the top of the disc 5 by reciprocating the hand plate 4. Due to the reciprocating rotation of the hand plate 4, when the hand plate 4 synchronously drives the bearing seat 2 and the limit plate 3 to move, the bearing seat 2 and the limit plate 3 can be reciprocated to prevent the bearing seat 2 and the limit plate 3 from being continuously driven and displaced. When the hand plate 4 stops reciprocating, the bearing seat 2 and the limit plate 3 are located in the position before adjustment. After the height is adjusted, the hand plate 4 is continuously rotated to make the hand plate 4 drive the limit plate 3 to continue to clamp the pipeline. At the same time, the hand plate 4 drives the plug plate 7 inside the base 6 to move outward. When the limit plate 3 clamps the pipeline, the hand plate 4 cannot rotate. At this time, one end of the plug plate 7 is inserted into the inner side of the embedded seat 8 for locking, so as to automatically connect the base 6 and the embedded seat 8.

The screw B94 drives the limit plates 3 to approach each other to clamp the pipeline. When the arc groove 11 supports a pipeline with a smaller diameter, the arc groove 11 supports the pipeline more stably.

A gear C47 is fixedly provided on one end of the shaft sleeve 46 located on the outer side of the box body 12. A connecting plate 48 is rotatably provided on the side of the hand plate 4 close to the gear C47. A tooth block 49 is fixedly provided on the other end of the connecting plate 48. The tooth block 49 is engaged with the outer side of the gear C47. A handle 410 is fixedly provided on the rotating end of the outer side of the hand plate 4 corresponding to the connecting plate 48. A latch 411 is inserted on the inner side of the handle 410. A pin hole 412 is opened on the side of the connecting plate 48 close to the hand plate 4. When the connecting plate 48 is parallel to the handle 410, the pin hole 412 and the latch 411 are coaxial. The hand plate 4 drives the gear C47 to rotate through the connecting plate 48. When the gear C47 rotates, it drives the box body 12 to rise and fall on the top of the disc 5.

[0065] When the hand plate 4 rotates continuously, the bearing seat 2, the limit plate 3 and the plug plate 7 can be driven to move at the same time. At this time, the handle 410 on the outside of the hand plate 4 is engaged with the connecting plate 48 through the latch 411. The hand plate 4 rotates on the outside of the box body 12 through the connecting shaft 41, and the bearing seat 2, the limit plate 3 and the plug plate 7 are driven to move through the connecting shaft 41. When the hand plate 4 rotates back and forth, the latch 411 is pulled out from the inner side of the pin hole 412, and the connecting plate 48 is rotated to one side of the handle 410, so that the tooth block 410 at the other end of the connecting plate 48 9 is automatically stuck on the outside of gear C47. When the hand plate 4 is turned, the gear C47 is pulled to rotate through the connecting plate 48. When the gear C47 rotates a certain angle, the hand plate 4 is directly reversed to make the connecting plate 48 push the tooth block 49 to move toward the origin and engage the gear C47 again. At this time, the gear C47 rotates in the same direction to drive the box 12 to rise and fall, and the hand plate 4 drives the connecting shaft 41 back to the origin to drive the bearing seat 2 and the limit plate 3 to reset. By analogy, the adjustment work of the device is completed by controlling the different rotations of the hand plate 4.

[0066] Reference Figure 2 and Figure 5 A toothed plate 51 is symmetrically fixed on the top of the disc 5, and a spiral toothed plate 52 is meshed on the outer side of the toothed plate 51. A gear D53 is fixed on the outer side of the spiral toothed plate 52. A gear E54 is meshed between two adjacent gears D53 on one side. The gear E54 is fixed on the other end of the shaft sleeve 46. When the gear E54 rotates, the hand plate 4 synchronously drives the plug plate 7 at the bottom of the disc 5 to move.

[0067] When the hand plate 4 drives the gear C47 to rotate, the gear C47 drives the gear E54 to rotate, and the gear E54 drives the outer gear D53 to rotate at the same time, so that the gear D53 drives the spiral toothed disc 52 on one side to rotate, and the spiral toothed disc 52 drives the toothed plate 51 to rise and fall. When the spiral toothed disc 52 stops rotating, the toothed plate 51 generates vertical pressure on the spiral toothed disc 52. At this time, the spiral toothed disc 52 will not rotate under force, and thus has a self-locking effect, so that the box body 12 can remain stable directly after being raised and lowered.

[0068] Reference Figure 6 and Figure 7 Two plug plates 7 are symmetrically arranged, and the plug plates 7 are slidably arranged at the bottom of the base 6 through a guide rail 71. A gear F72 is meshed between the two plug plates 7. A sliding hole 73 is opened on the outer side of the base 6 corresponding to the plug plate 7. Driven by the gear F72, the plug plate 7 passes through the sliding hole 73 and is inserted into the inner side of the slot 81. The slot 81 is opened on the inner side of the embedded seat 8. A transmission shaft 26 is fixedly arranged on the top of the gear F72, and a transmission block 25 is fixedly arranged on the top of the transmission shaft 26. The transmission block 25 is rotatably arranged at the bottom of the disc 5. A telescopic shaft A24 is fixedly arranged on the top of the transmission block 25, and the telescopic shaft A24 is slidably arranged on the inner side of the screw rod A23.

[0069] When the screw rod A23 rotates, it drives the internal telescopic shaft A24 to rotate, so that the telescopic shaft A24 drives the transmission block 25 at the bottom of the disc 5 to rotate, and the transmission block 25 drives the transmission shaft 26 to rotate, so that the transmission shaft 26 drives the gear F72 to rotate, and the gear F72 drives the plug plate 7 to be inserted into the inner side of the slot 81 along the guide rail 71, and the base 6 and the embedded seat 8 are locked through the plug plate 7.

[0070] Reference Figure 1 and Figure 7 Bolts 82 are evenly distributed on the top of the embedded seat 8. The bolts 82 are located on the inner side of the arc-shaped waist hole 14. The arc-shaped waist hole 14 is opened on the outer side of the annular seat 13. A bottom nut 83 is fixedly provided at the bottom of the annular seat 13 on the outer side of the bolts 82, and a top nut 84 is fixedly provided at the top of the annular seat 13.

[0071] When the base 6 is placed inside the embedded seat 8, the bolts 82 are inserted into the inner side of the arc-shaped waist hole 14. When the pipe support 1 is fine-tuning the angle, the pipe support 1 drives the annular seat 13 to rotate. At this time, the arc-shaped waist hole 14 rotates with the bolt 82, and when the pipe support 1 adjusts the height, the annular seat 13 moves up and down on the outside of the bolt 82. After the height and angle of the pipe support 1 are adjusted, the base 6 is fixed to the embedded seat 8. At this time, the bottom nut 83 on the outside of the rotating bolt 82 is moved close to the bottom of the annular seat 13, and the annular seat 13 is supported by the bottom nut 83, and then the top nut 84 is fastened to the top of the arc-shaped waist hole 14. Under the action of the bottom nut 83 and the top nut 84, the force of the pipe support 1 is directly transferred to the top of the embedded seat 8, and the box body 12 is fixed to prevent the box body 12 from rotating at will on the top of the disc 5.

[0072] Reference Figure 1-7 The present application also discloses a method for using the above pipeline limiting device, comprising the following steps:

[0073] S1. Place the base 6 on the inner side of the embedded seat 8, and then place the pipe on the top of the pipe support 1. At this time, the rollers 21 on both sides of the bearing seat 2 are located on the top of the pipe support 1, and the limit plates 3 between the rollers 21 are away from the pipe;

[0074] S2. Adjust the direction of the pipe support 1 according to the connection direction of the pipe. When adjusting, directly rotate the box 12 so that the box 12 drives the disc 5 to rotate on the inner side of the base 6;

[0075] S3, axially pushing the pipeline according to the connection distance of the pipeline, so that the pipeline moves through the roller 21, so as to connect two adjacent pipelines;

[0076] S4, continuously rotating the hand plate 4 drives the bearing seat 2 to move downward, and at the same time, the limit plate 3 slowly approaches the pipeline, and when the roller 21 is located inside the pipeline support 1, the pipeline is supported through the arc groove 11;

[0077] S5. At this time, the box body 12 is driven to rise and fall on the top of the disc 5 by reciprocating the hand plate 4, so as to adjust the height of the arc groove 11 according to the laying height of the pipeline. As the hand plate 4 reciprocates, when the hand plate 4 synchronously drives the bearing seat 2 and the limit plate 3 to move, the bearing seat 2 and the limit plate 3 can be reciprocated to prevent the bearing seat 2 and the limit plate 3 from being displaced by continuous driving.

[0078] S6. After the height is adjusted, the hand plate 4 is continuously rotated to make the hand plate 4 drive the limit plate 3 to continue to clamp the pipe. At the same time, the hand plate 4 drives the plug plate 7 inside the base 6 to move outward. When the limit plate 3 clamps the pipe, the hand plate 4 cannot be rotated. At this time, one end of the plug plate 7 is inserted into the inner side of the embedded seat 8 for locking, so as to automatically connect the base 6 and the embedded seat 8.

[0079] S7. Finally, the annular seat 13 is fixed by the bottom nut 83 and the top nut 84 on the outside of the bolt 82.

[0080] In summary, when the pipeline limiting device disclosed in the embodiment of the present application is used, first the base 6 is placed on the inner side of the embedded seat 8, and the bolts 82 are inserted into the inner side of the arc-shaped waist hole 14 during placement. Then the pipeline is placed on the top of the pipeline support 1. At this time, the rollers 21 on both sides of the bearing seat 2 are located on the top of the pipeline support 1, and the limiting plate 3 between the rollers 21 is away from the pipeline. The direction of the pipeline support 1 is adjusted according to the connection direction of the pipeline. When adjusting, the box body 12 is directly rotated to make the box body 12 drive the disc 5 to rotate on the inner side of the base 6. At this time, the arc-shaped waist hole 14 rotates with the bolt 82, and then the pipeline is pushed axially according to the connection distance of the pipeline, so that the pipeline is moved through the roller 21, so as to facilitate the connection of two adjacent pipelines. Then the hand plate 4 is continuously rotated to connect the two adjacent pipelines. The disk 4 drives the connecting shaft 41 to rotate, so that the connecting shaft 41 drives the active bevel gear 42 to rotate, and the active bevel gear 42 drives the driven bevel gear 43 to rotate, so that the driven bevel gear 43 drives the bottom gear A44 to rotate, and the gear B45 on the outside of the screw rod A23 is driven to rotate through the gear A44, so that the screw rod A23 drives the outer support plate 22 to descend. When the roller 21 is located inside the pipeline support 1, the pipeline is supported through the arc groove 11. At this time, the height of the arc groove 11 is adjusted according to the laying height of the pipeline. When adjusting, the pin 411 is pulled out from the inside of the pin hole 412, and the connecting plate 48 is rotated to one side of the handle 410, so that the tooth block 49 at the other end of the connecting plate 48 is automatically stuck on the outside of the gear C47. When the hand disk 4 is rotated, the connecting plate 48 is pulled The movable gear C47 rotates. When the gear C47 rotates a certain angle, the hand plate 4 is directly reversed to make the connecting plate 48 push the tooth block 49 to move toward the origin and engage the gear C47 again. At this time, the gear C47 rotates in the same direction to drive the box body 12 to rise and fall, and the hand plate 4 drives the connecting shaft 41 back to the origin to drive the bearing seat 2 and the limit plate 3 to reset. By analogy, when the gear C47 rotates, it drives the gear E54 to rotate, and the gear E54 drives the outer gear D53 to rotate at the same time, so that the gear D53 drives the spiral toothed disc 52 on one side to rotate, and the spiral toothed disc 52 drives the toothed plate 51 to rise and fall. When the spiral toothed disc 52 stops rotating, the toothed plate 51 generates vertical pressure on the spiral toothed disc 52. At this time, the spiral toothed disc 52 will not rotate under force, thereby having a self-locking effect, so that The box body 12 remains stable directly after being raised or lowered. After the height of the pipe support 1 is adjusted, the connecting plate 48 is locked with the handle 410 through the latch 411, and the hand plate 4 is continuously rotated to store the bearing seat 2 into the box body 12. At the same time, the screw rod A23 drives the worm 91 to rotate, so that the worm 91 drives the outer worm wheel 93 to rotate at the same time, so that the worm wheel 93 drives the inner screw rod B94 to rotate, and the screw rod B94 drives the limit plates 3 to approach each other to clamp the pipe. When the arc groove 11 supports a pipe with a smaller diameter, the arc groove 11 supports the pipe more stably, and when the screw rod A23 rotates, it drives the internal telescopic shaft A24 to rotate, so that the telescopic shaft A24 drives the transmission block 25 at the bottom of the disc 5 to rotate, and the transmission shaft 26 is driven to rotate through the transmission block 25.The transmission shaft 26 drives the gear F72 to rotate, and the gear F72 drives the plug plate 7 to be inserted into the inner side of the slot 81 along the guide rail 71, and the base 6 and the embedded seat 8 are locked by the plug plate 7. Finally, the bottom nut 83 on the outside of the bolt 82 is rotated to approach the bottom of the annular seat 13, and the annular seat 13 is supported by the bottom nut 83, and then the top nut 84 is fastened to the top of the arc waist hole 14. Under the action of the bottom nut 83 and the top nut 84, the force of the pipe support 1 is directly transferred to the top of the embedded seat 8, and the box body 12 is fixed to prevent the box body 12 from rotating at will on the top of the disc 5.
