Description

Technical Field

[0001] The present disclosure relates to the technical field of pipeline installation, and in particular to a docking device for pipeline installation. Background Art

[0002] The economizer is a device installed at the bottom of the flue at the rear of the boiler to recover the waste heat of the exhaust gas. It heats the boiler feed water to a saturated water heating surface under drum pressure. Since it absorbs the heat of the high-temperature flue gas, it reduces the exhaust temperature of the flue gas and saves energy. However, during the use of the economizer, coal ash will accumulate. The accumulated coal ash needs to be continuously transported and discharged by an air pump, which must be achieved through the ash conveying and air supply pipeline. In the actual coal ash conveying process, the ash conveying and air supply pipeline is often installed in sections. The existing pipe docking method is not labor-saving enough and is not convenient for quickly assisting the docking flange. Manual operation is time-consuming and labor-intensive, and there are also safety hazards. It is easy to cause the pipe to deform into an arc, and it is not convenient to control the pipe support and measure it in time. As a result, it is difficult to install bolts when docking the pipe flanges. Utility Model Content

DETAILED DESCRIPTION

[0037] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0038] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" are defined with respect to the actual arrangement direction of the docking device for pipe installation during use, and directional terms such as "inner" and "outer" are defined with respect to the outlines of the corresponding components. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise indicated, identical reference numerals in different drawings denote identical or similar elements.

[0039] According to one embodiment of the present disclosure, Figures 1 to 6 As shown, a docking device for pipeline installation is provided, comprising two oppositely arranged bases 1, two rotating members 2, an adjusting portion 3 and a supporting portion 4. The two rotating members 2 can be rotatably arranged on the bases 1, and the rotating members 2 are used to support the pipeline and can rotate relative to the pipeline. The adjusting portion 3 can be passed through the two bases 1, and the adjusting portion 3 is respectively connected to the two bases 1 to adjust the distance between the two bases 1. The two ends of the supporting portion 4 are respectively connected to a base 1, and the supporting portion 4 includes a hydraulic cylinder 41, and the output end of the hydraulic cylinder 41 is used to support the pipeline.

[0040] Through the above technical solution, a support portion 4 is connected between the two bases 1 to support the middle section of the pipeline, reducing pipeline deformation, facilitating docking of the flange at the end of the pipeline, and ensuring that the cross section of the pipeline flange is vertically connected to the flange of the adjacent pipeline, effectively ensuring the flange connection seal and preventing dust from entering the pipeline. The rotating member 2 can support the pipeline and rotate at the same time, which can also make the pipeline rotation adjustment easier. Combined with the support of the hydraulic cylinder 41 in the support portion 4 in the middle section, it can save installation time and physical effort, and can save effort and quickly install the pipeline. In addition, an adjustment portion 3 is provided between the two bases 1 to adjust the distance between the two bases 1, so that the docking device can adapt to pipeline sections of various lengths, thereby improving the versatility of the docking device.

[0041] It should be noted that one docking device is mounted on a pipe. When two pipes are docked, a docking device is positioned below each pipe to provide support. Furthermore, the docking device may include multiple rollers 5, which may be spaced apart below the base 1. This allows the docking device to be moved to any position, facilitating docking operations for pipes at different locations. Multiple rollers 5 may be positioned at the corners of the base 1 to provide enhanced support for the base 1.

[0042] Furthermore, if Figures 1 to 5 As shown, a sleeve 10 is connected to one of the bases 1, and the support portion 4 may include a mounting tube 42, a threaded rod 43, and a slider 44. One end of the mounting tube 42 is movably inserted into the sleeve 10, and the other end is fixedly connected to the other base 1. The mounting tube 42 is provided with an opening 421 extending along the extension direction of the mounting tube 42. The threaded rod 43 is rotatably disposed in the mounting tube 42. One end of the slider 44 is matingly connected to the threaded rod 43, and the other end is connected to the hydraulic cylinder 41 through the opening 421. The base 1 with the sleeve 10 can be moved along the mounting tube 42 to adjust the relative position between the two bases 1. By rotating the threaded rod 43, the matching slider 44 can be driven to move along the extension direction of the opening 421, thereby adjusting the position of the hydraulic cylinder 41 on the slider 44. Here, the opening 421 can be opened on the top wall or side wall of the mounting tube 42, and this is not limited in the present disclosure. When the opening 421 is provided on the top wall of the mounting tube 42, the slider 44 may be an inverted L-shaped structure, with the horizontal end of the inverted L-shaped structure connected to the hydraulic cylinder 41 and the vertical end connected to the threaded rod 43. Here, the end of the threaded rod 43 may be provided with an adjustment handle to facilitate rotation of the threaded rod 43 within the mounting tube 42. Alternatively, an auxiliary rotating member connected to the threaded rod 43 may be provided at the opening 421, but this disclosure is not limited thereto.

[0043] Furthermore, if Figure 1 、 Figure 3 and Figure 4 As shown, the hydraulic cylinder 41 may include a cylinder body 411 and a piston rod 412. The cylinder body 411 may be connected to a slider 44, and the piston rod 412 is disposed in the cylinder body 411 for reciprocal movement. The end of the piston rod 412, away from the cylinder body 411, passes through the slider 44 and is used to support the pipeline. The piston rod 412 may contact the pipeline to support the middle section of the pipeline.

[0044] Furthermore, if Figure 4As shown, the piston rod 412 can be provided with multiple scale lines, and the slider 44 is provided with a marking frame 441 that can correspond to the scale lines. In this way, the positions of the marking frame 441 corresponding to multiple points on newly manufactured pipes of different sizes can be recorded as reference data. When the pipes need to be docked and installed, after the pipes are placed on the docking device, the position of the piston rod 412 is adjusted to support the pipes. At this time, the positions of the scale lines corresponding to the marking frame 441 are recorded, and then compared with the reference data of pipes of the same specifications to determine whether the pipes have sunk and deformed. Based on the data of the sinking deformation, the original data of the pipe can be restored through the deformation data to facilitate the alignment of the flanges at the pipe ends. At the same time, the obtained sinking deformation data can also be used to determine whether the pipe to be replaced meets the qualification standards.

[0045] According to one embodiment of the present disclosure, Figure 1 、 Figure 3 and Figure 6 As shown, the adjustment part 3 may include a screw rod 31 that passes through the two bases 1 in sequence. The screw rod 31 is rotatably arranged in the base 1 for adjusting the position of the base 1 relative to the screw rod 31. An adjustment handle 311 is provided at one end of the screw rod 31. The adjustment handle 311 is provided on the outside of one of the bases 1 and can abut against the corresponding base 1. The adjusting handle 311 can facilitate the rotation of the screw rod 31. Here, the through hole of the screw rod 31 in the base 1 near the side of the adjusting handle 311 can be a smooth through hole, that is, the screw rod 31 can only rotate relative to the base 1 and cannot move horizontally relative to the base 1. At the same time, a limiter can also be provided on the screw rod 31, which is provided at the position where the screw rod 31 passes through the base 1 near the side of the adjusting handle 311, so as to limit the base 1 near the side of the adjusting handle 311 between the limiter and the adjusting handle 311. A threaded hole that cooperates with the screw rod 31 is provided in the base 1 away from the adjusting handle 311, so that when the screw rod 31 is rotated, the depth of the screw rod 31 penetrating into the base 1 away from the adjusting handle 311 can be adjusted, thereby adjusting the distance between the two bases 1. Of course, both bases 1 can also be provided with threaded holes that cooperate with the screw rod 31, and this disclosure is not limited to this.

[0046] Furthermore, if Figure 1 The adjustment portion 3 may further include a sliding shaft 32. A corresponding slide groove 11 is provided on the base 1 to match the sliding shaft 32. Both the sliding shaft 32 and the slide groove 11 are spaced apart from the screw rod 31. Two sliding shafts 32 may be provided, one on each side of the screw rod 31, to enhance the strength of the adjustment portion 3 and reduce the possibility of breakage of the screw rod 31. This also allows for more stable movement of the bases 1 when adjusting the distance between the two bases 1. The sliding shaft 32 may be a square shaft or square tube, or a round shaft or round tube.

[0047] According to one embodiment of the present disclosure, Figure 1 and Figure 3 As shown, the base 1 may include a base plate 12, a sleeve rod 13, and a core rod 14. The base plate 12 may be inserted into the adjustment portion 3. One end of the sleeve rod 13 is fixed to the base plate 12, while the other end extends in the height direction. The core rod 14 is reciprocally mounted within the sleeve rod 13, and the rotatable member 2 is disposed at the end of the core rod 14 away from the sleeve rod 13. This allows the height of the rotatable member 2 to be adjusted, and the height of the corresponding pipe placement can also be adjusted, thereby improving the versatility of the docking device. The core rod 14 may be a hollow structure, with a driver 141 disposed within it to drive the core rod 14 up and down within the sleeve rod 13. The driver 141 may be a hydraulic cylinder or a pneumatic cylinder. Alternatively, the core rod 14 and sleeve rod 13 may be pneumatic telescopic rods. The core rod 14 and sleeve rod 13 may be equipped with self-locking devices, such as multiple through-holes in the sleeve rod 13 along the height direction and a push-button on the core rod 14 that engages with the through-holes. This is not limited in this disclosure.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, the rotating member 2 may include two support rollers 21 spaced apart on the core rod 14. The two support rollers 21 may be positioned at the bottom of the pipe. The two support rollers 21 support the pipe from both sides of the bottom. When the pipe is rotated, rolling friction occurs between the pipe and the support rollers 21 due to their ability to rotate, which reduces effort during pipe rotation.

[0049] Furthermore, if Figure 1 and Figure 2 As shown, a curved plate 15 may also be provided at the end of the core rod 14 away from the sleeve rod 13. The middle region of the curved plate 15 is connected to the core rod 14, and the curved plate 15 is recessed toward the side closer to the core rod 14. Two support rollers 21 are respectively provided at either end of the curved plate 15. When a small circular pipe is supported on the two support rollers 21, the bottom of the curved surface of the pipe will be lower than the center of the support rollers 21. Therefore, the plate connecting the two support rollers 21 is the curved plate 15. Because the curved plate 15 protrudes away from the pipe, it can effectively avoid the pipe, preventing contact with the pipe that affects the pipe's rotation and adjustment.

[0050] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0052] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
