Description

Technical Field

[0001] This invention relates to the field of auxiliary connections for PCCP pipe joints, and specifically to an auxiliary structure for PCCP pipe joint installation and its usage method. Background Technology

[0002] In the construction of PCCP pipelines, the connection installation typically employs a combination of "internal pull" and "external pull" methods: a gantry crane is used to lift the pre-installed pipeline off the ground; a load-bearing beam slightly shorter than the pipeline diameter is placed inside the first installed pipeline section and erected at the pipeline spigot end; a crossbeam with a diameter larger than the pipeline is erected at the outer end of the pre-installed pipeline socket; the two beams are connected using wire ropes and a hand-operated hoist, and the distance between the two beams is brought closer by the hand-operated hoist, thus achieving pipeline installation. Since pipelines of different diameters have different diameters and weights, a single load-bearing beam cannot accommodate the installation of multiple diameter pipelines. Furthermore, even pipelines of the same size can have different weights during connection, necessitating leveling. However, current leveling methods mostly require manual adjustment, affecting connection efficiency. Therefore, an auxiliary structure for PCCP pipeline joint installation is proposed to address these issues. Summary of the Invention

[0003] To address the problems of existing technologies, this invention provides an auxiliary structure for PCCP pipe joint installation and its usage method, which has the advantage of adapting to different pipe diameters and solves the problem that existing technologies cannot adapt to different pipe diameters.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A PCCP pipe joint installation auxiliary structure includes an installation box, movable wheels, a circular through hole, a support component, a monitoring component, and a storage cavity. The top of the movable wheels is fixedly connected to the bottom of the installation box. The circular through hole is opened inside the installation box. The storage cavity is opened inside the installation box. The support component is located inside the storage cavity. The monitoring component is located inside the installation box.

[0006] The support assembly includes two support plates located inside the storage cavity. Movable rods are movably connected to the left and right sides of the bottom of each support plate. The ends of the two movable rods furthest from the support plates are slidably connected to the bottom of the inner wall of the storage cavity. Each support plate has a strip-shaped groove on its top. Two movable blocks are slidably connected inside each of the two strip-shaped grooves. Compression springs are fixedly installed at opposite ends of each of the four movable blocks. The ends of the four compression springs furthest from the movable blocks are fixedly connected to the inner wall of the strip-shaped grooves. Support rods are fixedly installed on the tops of each of the four movable blocks. Semi-circular locking blocks are fixedly installed on the tops of each of the four support rods. The four semi-circular locking blocks are located inside circular through holes. Tension springs are fixedly installed between each pair of the four movable rods.

[0007] The monitoring component includes two monitoring probes, two connecting wires, a processor, and a display screen. The two monitoring probes are respectively installed at the top and bottom of the inner wall of the circular through-hole. The processor is fixedly installed inside the mounting box. One end of each of the two connecting wires is electrically connected to the monitoring probe, and the end of the two connecting wires away from the monitoring probe is electrically connected to the processor. One end of the processor is electrically connected to a transmission wire. The left side of the display screen is detachably connected to the right side of the mounting box. The processor and the display screen work together through the transmission wire.

[0008] Two strip grooves are formed at the bottom of the inner wall of the storage cavity, and the outer surfaces of the four moving rods are slidably connected to the inner walls of the two strip grooves.

[0009] The inside of the circular through hole is provided with an arc-shaped groove. The bottom of the arc-shaped groove is connected to the inside of the storage cavity, and the inner wall of the arc-shaped groove is slidably connected to the outer surface of the support rod.

[0010] A leveling mechanism is installed between the two support plates. This mechanism includes a level and two telescopic support blocks. The level is positioned between the two support plates, and signal transmitters are attached to both ends of the level. The two telescopic support blocks are installed at the bottom of the support plates, with their bottoms fitting against the bottom of the inner wall of the storage cavity. Each telescopic support block has a built-in signal receiver, which works in conjunction with the signal transmitter. The signal transmitter uses a 433MHz wireless radio frequency module to transmit the horizontal deviation signal via pulse coding. When the level detects a tilt angle exceeding ±0.5°, it triggers a signal transmission. After receiving the signal, the signal receiver uses its built-in MCU to analyze the deviation direction and angle, controlling the telescopic support blocks to use electric push rods for stepless telescopic movement within a range of 0-50mm. Mechanical limit blocks are also included to prevent excessive telescopic movement. The level is rigidly fixed to the connecting beam between the two support plates with bolts, ensuring that the detection benchmark is synchronized with the support plates. When the support assembly adjusts the pipe position, causing the support plates to tilt, the level monitors this in real time and initiates leveling within 0.3 seconds, with leveling accuracy controlled within ±0.2°. The system is also equipped with a buzzer alarm, which will automatically sound an alarm when the signal transmission is interrupted or the travel of the telescopic support block exceeds the threshold, and will display the fault code on the display screen.

[0011] An arc-shaped protective block is fixedly installed inside the semi-circular card block, and the arc-shaped protective block has evenly distributed arc-shaped grooves inside.

[0012] The top of the movable rod is movably connected to a hinge seat, and the top of the hinge seat is fixedly connected to the bottom of the support plate.

[0013] A hanging block is fixedly installed on the right side of the mounting box, and a hanging slot is opened on the left side of the display screen. The inside of the hanging slot is used in conjunction with the outer surface of the hanging block.

[0014] A method for using a PCCP pipe joint installation auxiliary structure, wherein the PCCP pipe joint installation auxiliary structure is any one of the PCCP pipe joint installation auxiliary structures described above, the method of use includes the following steps:

[0015] S1: Insert the pipes that need to be installed together from both ends of the circular through hole;

[0016] S2: Use support components to support the two pipes;

[0017] S3: Use a leveling mechanism to check whether the two pipes are on the same horizontal plane, so that the two pipes are on the same horizontal plane;

[0018] S4: When connecting pipes, use monitoring components to view the interior in real time.

[0019] Compared with the prior art, the beneficial effects of the invention are: (1) The present invention achieves support by setting up an installation box, moving wheels, circular through holes, support components, monitoring components, storage cavity and horizontal mechanism in combination. At the same time, the two pipes are made horizontal by using a level, which makes the connection effect better and solves the problem that the existing technology cannot adapt to different diameters. The PCCP pipe joint installation auxiliary structure has the advantage of adapting to different diameters.

[0020] (2) By setting a strip groove and using the inside to cooperate with the outer surface of the moving rod, the present invention can not only restrict the moving rod, but also make the movement trajectory of the moving rod more stable.

[0021] (3) By setting an arc-shaped groove and using the inside to cooperate with the outer surface of the support rod, the present invention can not only make the movement of the support rod better, but also restrict the position of the support rod.

[0022] (4) This invention uses a level to sense whether the two support plates are at the same horizontal position. The level is rigidly fixed to the connecting beam between the two support plates by bolts to ensure that the detection benchmark is synchronized with the support plates. The signal transmitters at both ends use 433MHz wireless radio frequency modules. This module utilizes high-frequency radio frequency technology and has the characteristics of short range, low complexity, low power consumption, low data rate and low cost. When the tilt angle of the support plate is detected to exceed ±0.5°, the signal transmitter sends a deviation signal to the signal receiver in the corresponding telescopic support block through pulse coding. The signal receiver has a built-in MCU. After parsing the signal, it controls the telescopic support block to use electric push rod drive to achieve stepless telescopic extension within the range of 0-50mm. At the same time, mechanical limit blocks are set to prevent excessive extension. During the leveling process, the level monitors in real time and starts adjustment within 0.3 seconds, and finally controls the tilt error within the range of ±0.2°. The system is also equipped with a buzzer alarm. When the signal transmission is interrupted or the travel of the telescopic support block exceeds the threshold, an alarm is automatically triggered and the fault code is displayed on the screen to ensure construction safety and connection accuracy.

[0033] The present invention will be further described in detail below through embodiments. These embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides an auxiliary structure for installing PCCP pipe joints, including an installation box 1, casters 2, a circular through hole 3, a support assembly 4, a monitoring assembly 5, and a storage cavity 6. The top of the casters 2 is fixedly connected to the bottom of the installation box 1. The circular through hole 3 and the storage cavity 6 are both located inside the installation box 1. The support assembly 4 is disposed within the storage cavity 6, and the monitoring assembly 5 is disposed within the installation box 1.

[0035] The support assembly 4 includes two support plates 41, both located inside the storage cavity 6. Movable rods 42 are movably connected to the left and right sides of the bottom of each support plate 41. The ends of these moving rods 42 away from the support plate 41 are slidably connected to the bottom of the inner wall of the storage cavity 6. A strip groove 43 is formed at the top of the support plate 41, and two moving blocks 44 are slidably connected within the strip groove 43. Compression springs 45 are fixed to the opposite ends of each of the four moving blocks 44, and the other ends of the compression springs 45 are fixedly connected to the inner wall of the strip groove 43. Support rods 46 are fixed to the top of the moving blocks 44, and semi-circular locking blocks 47 are fixed to the top of the support rods 46. These semi-circular locking blocks 47 are located inside the circular through holes 3. Tension springs 48 are fixed between each pair of the four moving rods 42. Supporting inclined blocks are also fitted onto the outer surface of the moving rods 42, with their bottoms fitting against the top of the support plate 41, thereby increasing the vertical support force of the moving rods 42. At the same time, it can enhance the support force on both sides of the moving rod 42 and improve the support effect. The diameter of the circular through hole 3 is larger than the diameter of the semi-circular clamping block 47, so that it can better adapt when encountering pipes of different diameters. Adaptive diameter mechanism: When the pipe is inserted into the circular through hole, it squeezes the semi-circular clamping block 47, and pushes the moving block 44 through the support rod 46 to compress the squeezing spring 45, so as to achieve clamping of pipes of different diameters.

[0036] The monitoring component 5 includes two monitoring probes 51, two connecting wires 52, a processor 53, and a display screen 54. The two monitoring probes 51 are respectively installed at the top and bottom of the inner wall of the circular through hole 3. The processor 53 is fixedly installed inside the mounting box 1. One end of each of the two connecting wires 52 is electrically connected to the monitoring probe 51, and the end of each connecting wire 52 away from the monitoring probe 51 is electrically connected to the processor 53. One end of the processor 53 is electrically connected to a transmission wire 55. The left side of the display screen 54 is detachably connected to the right side of the mounting box 1. The processor 53 and the display screen 54 are used together through the transmission wire 55.

[0037] refer to Figure 6 Two strip grooves 43 are provided at the bottom of the inner wall of the storage cavity 6, and the outer surfaces of the four moving rods 42 are slidably connected to the inner walls of the two strip grooves 43.

[0038] The above solution involves setting a strip groove 43, which works in conjunction with the outer surface of the moving rod 42. This not only restricts the moving rod 42 but also makes its movement trajectory more stable.

[0039] refer to Figure 6 An arc-shaped groove 8 is provided inside the circular through hole 3. The bottom of the arc-shaped groove 8 is connected to the inside of the storage cavity 6. The inner wall of the arc-shaped groove 8 is slidably connected to the outer surface of the support rod 46.

[0040] The above solution involves setting an arc-shaped groove 8, which fits into the outer surface of the support rod 46. This not only improves the movement of the support rod 46 but also restricts its position.

[0041] refer to Figure 8 A horizontal mechanism 9 is provided between the two support plates 41. The horizontal mechanism 9 includes a level 91 and two telescopic support blocks 92. The level 91 is rigidly fixed to the connecting beam between the two support plates 41 by bolts. A 433MHz wireless radio frequency signal transmitter 93 is used at both ends of the level 91. The two telescopic support blocks 92 are respectively installed at the bottom of the support plates 41. They are driven by electric push rods and have a signal receiver 94 and a mechanical limit block embedded inside. The bottom of the two telescopic support blocks 92 fits against the bottom of the inner wall of the storage cavity 6. The signal receiver 94 has a built-in MCU and works with the signal transmitter 93 to realize signal analysis and motion control.

[0042] The above scheme employs a level 91 that continuously senses the horizontal state of the two support plates 41. When the detected tilt angle exceeds ±0.5°, the corresponding signal transmitter 93 sends a pulse-coded signal. The signal receiver 94 receives this signal and controls the telescopic support block 92 to extend and retract steplessly within a range of 0-50mm. Leveling is initiated within 0.3 seconds, and the error is controlled within ±0.2°. The system is equipped with a buzzer alarm that automatically sounds when the signal is interrupted or the extension / retraction stroke exceeds the threshold. Simultaneously, the display screen 54 shows the fault code, ensuring pipe connection accuracy and construction safety.

[0043] refer to Figure 9 An arc-shaped protective block 10 is fixedly installed inside the semi-circular locking block 47, and the arc-shaped protective block 10 has evenly distributed arc-shaped grooves 11 inside.

[0044] The above solution employs an arc-shaped protective block 10, whose arc design allows it to conform to the outer surface of the pipe, preventing direct contact between the metal support components and the pipe, thus reducing surface scratches or concrete layer damage caused by rigid compression. The arc-shaped protective block 10 has an arc-shaped groove 11 inside, which increases the friction with the pipe surface, preventing collisions caused by sliding during connection, and also avoiding localized pressure concentration on the outer wall of the pipe from the support components.

[0045] refer to Figure 6 The top of the movable rod 42 is movably connected to a hinge seat 12, and the top of the hinge seat 12 is fixedly connected to the bottom of the support plate 41.

[0046] The above solution is adopted: by setting the hinge seat 12, the moving rod 42 can be moved more conveniently, and there will be no jamming when resetting.

[0047] refer to Figure 4 A hanging block 13 is fixedly installed on the right side of the mounting box 1, and a hanging groove 14 is provided on the left side of the display screen 54. The interior of the hanging groove 14 is used in conjunction with the outer surface of the hanging block 13.

[0048] By adopting the above solution: by setting the hanging block 13 and the hanging slot 14 in cooperation, the display screen 54 can be made detachable. (7) The present invention enables the display screen to be detachable by setting the hanging block and the hanging slot in cooperation.

[0050] (1) Insert the pipes that need to be installed together into the two ends of the circular through hole 3;

[0051] (2) Use support component 4 to support the two pipes;

[0052] (3) Use the horizontal mechanism 9 to check whether the two pipes are on the same horizontal plane, so that the two pipes are on the same horizontal plane;

[0053] (4) When connecting pipes, use monitoring component 5 to monitor the interior in real time.
