Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and specifically to an auxiliary device and method for pipeline installation in prefabricated modular buildings. Background Technology

[0002] Prefabricated modular buildings are a new type of building based on industrialized production methods. Their main characteristic is that some or all of the building's structural components are prefabricated in a factory and then transported to the construction site for assembly and connection to form a complete building system.

[0003] In prefabricated modular buildings, pipe installation, as a key concealed project, has undergone improvements and optimizations compared to traditional construction. These improvements are mainly reflected in prefabrication and integration, standardized interfaces, intelligent positioning, and modular components. Therefore, for prefabricated modular buildings, the installation of concealed functions such as pipes primarily focuses on standardized interfaces and positioning. In actual installation, quick installation can be achieved simply by accurately positioning the standardized interfaces.

[0004] However, since concealed works such as pipelines are often hidden in the main building structure, the positioning of standardized interfaces cannot be directly observed due to their concealed structure. Therefore, installation often requires multiple attempts. This is especially true for high-precision pipeline installation, where conventional multiple attempts are insufficient and auxiliary tools are needed.

[0005] The existing auxiliary tools are mainly used for the horizontal installation of pipes. The specific structure consists of a fixed clamp and a movable clamp. The fixed clamp is held on the outer surface of the fixed pipe, while the movable clamp is held on the outer surface of the pipe to be installed. Then, by moving the movable clamp closer to the fixed clamp, the pipe to be installed is moved closer to the fixed pipe, thereby assisting in the alignment of the pipe to be installed with the fixed pipe.

[0006] Since the pipes to be installed come in various diameters, while the fixed and movable clamps are of a fixed type, although both can hold pipes of different diameters, during the clamping process, there is a possibility that the central axis of the clamp and the central axis of the pipe are not on the same straight line. This will cause the central axis of the fixed pipe held by the fixed clamp to be misaligned with the central axis of the pipe to be installed held by the movable clamp, resulting in the pipe to be installed and the fixed pipe being misaligned.

[0007] Especially for vertical pipe installations, the misalignment of pipes caused by the misalignment of the central axis of the clamp and the central axis of the pipe is a serious problem. Summary of the Invention

[0008] The purpose of this invention is to provide an auxiliary device and method for pipe installation in prefabricated modular buildings, so as to solve the technical problem that existing pipe installation methods and devices cannot be used for indoor vertical pipe installation.

[0009] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: In a first aspect of the present invention, a pipe installation auxiliary device for prefabricated modular buildings is provided, including a column, a first fixing clamp fixedly connected to one side of the column, and at least one second fixing clamp provided on the top of the first fixing clamp. The second fixing clamp is slidably connected to the column, so that the second fixing clamp clamping the pipe to be installed slides downward and the bottom cross section of the pipe to be installed matches the top cross section of the fixed pipe clamped by the first fixing clamp to complete the pipe installation. A positioning structure is provided on the side of the column near the fixed pipe. The side of the positioning structure near the fixed pipe is on the same vertical plane, and the positioning structure slides horizontally inside the column. After the second fixing clamp holds the pipe to be installed, the side of the positioning structure near the pipe to be installed slides horizontally to limit the horizontal position of the first fixing clamp and the second fixing clamp. This makes the distance from the central axis of the fixed pipe and the pipe to be installed to the positioning structure equal, and makes the central axis of the fixed pipe held by the first fixing clamp and the central axis of the pipe to be installed held by the second fixing clamp on the same straight line.

[0010] Furthermore, the positioning structure includes a first limiting plate and at least one second limiting plate. The first limiting plate and the second limiting plate slide horizontally on the column, and the first limiting plate is disposed at the bottom of the second limiting plate. The sides of the first limiting plate and the second limiting plate away from the column are on the same vertical plane. A connecting plate parallel to the column is provided on the side of the column away from the first fixing clamp. The first limiting plate and the second limiting plate are both fixedly connected to the connecting plate, and the first limiting plate and the second limiting plate are moved simultaneously by moving the connecting plate in the horizontal direction.

[0011] Furthermore, a threaded rod is rotatably connected to the connecting plate via a bearing. A threaded hole is provided on one side of the column, and the threaded rod is threaded into the threaded hole. By rotating the threaded rod, the threaded rod moves left and right relative to the column, thereby driving the first limiting plate and the second limiting plate to move left and right relative to the column.

[0012] Furthermore, both the first and second limiting plates are slidably connected to the adhesive plates on the side away from the column. A suction cup is fixedly connected to the adhesive plate on the side away from the column, so that when the second fixing clamp moves the pipe to be installed downward, it simultaneously moves the adhesive plate downward, causing the pipe to be installed to move relative to the second limiting plate.

[0013] Furthermore, a positioning block is fixedly connected to the top of the first fixing clamp, a positioning hole is provided on the top of the positioning block, and a positioning rod is fixedly connected to the bottom of the second fixing clamp, so that the positioning rod matches the positioning hole and the positioning rod is inserted into the positioning hole. As the second fixing clamp moves the pipe to be installed downwards, the positioning rod is inserted into the positioning hole, and the positioning rod slides downwards inside the positioning hole until the bottom of the pipe to be installed contacts the top of the fixing pipe.

[0014] Furthermore, a guide groove is provided at the top of the positioning hole, and the top diameter of the guide groove is larger than its bottom diameter; The depth of the positioning hole is greater than the length of the positioning rod.

[0015] Furthermore, multiple universal ball bearings are fixedly installed on the inner wall of the guide groove. During the downward movement of the positioning rod, the downward movement path of the positioning rod is corrected under the guidance of the universal ball bearings.

[0016] In a second aspect of the present invention, a method for assisting pipe installation in prefabricated modular buildings is provided, employing the aforementioned auxiliary device for pipe installation in prefabricated modular buildings, comprising the following steps: This ensures that the pipe to be installed is parallel to the column and is clamped and fixed by the second fixing clamp; Move the column with the pipe to be installed to the side of the fixed pipe and clamp the fixed pipe with the first fixing clamp. This causes the second fixing clamp to move the pipe to be installed down until it matches the fixed pipe.

[0017] Furthermore, during the process of moving the column clamping the pipe to be installed to the side of the fixed pipe, the positioning structure ensures that the central axis of the fixed pipe and the central axis of the pipe to be installed are on the same straight line.

[0018] Furthermore, during the process of the second fixing clamp moving the pipe to be installed downwards, the corresponding limiting structures on the second fixing clamp and the first fixing clamp limit the downward movement path of the pipe to be installed.

[0019] Compared with the prior art, the present invention has the following advantages: 1. The installation auxiliary device provided by the present invention has a positioning structure. After the second fixing clamp holds and fixes the pipe to be installed, the positioning structure limits the position of the central axis of the fixed pipe and the pipe to be installed. This avoids the problem that the central axis of the first fixing clamp and the central axis of the fixed pipe are deviated due to the first fixing clamp when installing pipes of different diameters. This ensures that the central axis of the fixed pipe held by the first fixing clamp and the central axis of the pipe to be installed held by the second fixing clamp are always on the same straight line. This allows the device to quickly align the pipe to be installed with the fixed pipe, and is not affected by the pipe diameter or the fixing clamp structure.

[0020] 2. The installation assistance method provided by the present invention moves the column with the pipe to be installed to the side of the fixed pipe and clamps the fixed pipe with the first fixing clamp; the second fixing clamp drives the pipe to be installed to move down until it matches the fixed pipe to complete the pipe installation, and the positioning structure makes the central axis of the fixed pipe and the central axis of the pipe to be installed on the same straight line, which can quickly align the pipe to be installed with the fixed pipe and is not affected by the pipe diameter and the fixing clamp structure.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention provides a pipe installation auxiliary device in prefabricated modular buildings, including a column 1, a first fixing clamp 2 fixedly connected to one side of the column 1, and at least one second fixing clamp 3 provided on the top of the first fixing clamp 2. The second fixing clamp 3 is slidably connected to the column 1, so that the second fixing clamp 3 clamping the pipe to be installed slides downward and the bottom cross section of the pipe to be installed matches the top cross section of the fixed pipe clamped by the first fixing clamp 2 to complete the pipe installation. A positioning structure is provided on the side of the column 1 near the fixed pipe. The side of the positioning structure near the fixed pipe is on the same vertical plane, and the positioning structure slides horizontally inside the column 1. After the second fixing clamp 3 clamps the pipe to be installed, the side of the positioning structure near the pipe to be installed slides horizontally to limit the horizontal position of the first fixing clamp 2 and the second fixing clamp 3. This makes the distance from the central axis of the fixed pipe and the pipe to be installed to the positioning structure equal, and makes the central axis of the fixed pipe clamped by the first fixing clamp 2 and the central axis of the pipe to be installed clamped by the second fixing clamp 3 on the same straight line.

[0026] Since the pipes to be installed come in various diameters, while the first clamp 2 and the second clamp 3 are of fixed sizes, although both the first clamp 2 and the second clamp 3 can clamp pipes of different diameters, during the clamping process, there is a possibility that the central axis of the clamp and the central axis of the pipe are not on the same straight line. This will cause the central axis of the fixed pipe clamped by the first clamp 2 to be not on the same straight line as the central axis of the pipe to be installed clamped by the second clamp 3, thus causing the pipe to be installed and the fixed pipe to be misaligned.

[0027] Especially for vertical pipe installations, the misalignment of pipes caused by the misalignment between the central axis of the clamp and the central axis of the pipe is a serious problem. Therefore, it is necessary to develop a pipe installation auxiliary device.

[0028] This embodiment incorporates a positioning structure. After the second clamp holds and fixes the pipe to be installed, the positioning structure limits the position of the central axis of the fixed pipe and the pipe to be installed. This avoids the problem of deviation between the central axis of the first clamp and the central axis of the fixed pipe due to the first clamp when installing pipes of different diameters. It ensures that the central axis of the fixed pipe held by the first clamp and the central axis of the pipe to be installed held by the second clamp are always on the same straight line. This allows the device to quickly align the pipe to be installed with the fixed pipe, regardless of the pipe diameter or the clamp structure.

[0029] In actual use, 1. the pipe to be installed is set parallel to the column 1, and the pipe to be installed is clamped and fixed by the second fixing clamp 3. The positioning structure is made to be in close contact with the surface of the pipe to be installed by the horizontal moving positioning structure. 2. Move the column 1 with the pipe to be installed to the side of the fixed pipe, and make the positioning structure close to the surface of the fixed pipe. Then, clamp the fixed pipe with the first fixing clamp 2. At this time, the positioning structure limits the fixed pipe, and the central axes of the two pipes are on the same straight line. 3. This causes the second fixing clamp 3 to move the pipe to be installed downwards until it matches the fixed pipe, thus completing the pipe installation.

[0030] The following is a detailed analysis of the specific structure of the positioning structure, such as... Figure 2 As shown, the positioning structure includes a first limiting plate 8 and at least one second limiting plate 9. The first limiting plate 8 and the second limiting plate 9 slide horizontally on the column 1, and the first limiting plate 8 is disposed at the bottom of the second limiting plate 9. The sides of the first limiting plate 8 and the second limiting plate 9 away from the column 1 are on the same vertical plane. A connecting plate 10 parallel to the column 1 is provided on the side of the column 1 away from the first fixing clamp 2. The first limiting plate 8 and the second limiting plate 9 are both fixedly connected to the connecting plate 10, and the first limiting plate 8 and the second limiting plate 9 can be moved simultaneously by moving the connecting plate 10 in the horizontal direction.

[0031] By providing a first limiting plate 8 and a second limiting plate 9 that can move left and right simultaneously, and with the side of the first limiting plate 8 and the second limiting plate 9 away from the column 1 on the same vertical plane, after the second fixing clamp 3 clamps the pipe to be installed, by moving the second limiting plate 9, the second limiting plate 9 is brought into contact with the outer surface of the pipe to be installed. At this time, the first limiting plate 8 also moves synchronously. When the column 1 with the pipe to be installed clamped is moved to the side of the fixed pipe, it is only necessary to bring the first limiting plate 8 into contact with the fixed pipe to limit the position of the column 1, thereby limiting the first fixing clamp 2. Then, the first fixing clamp 2 is clamped with the fixed pipe, which can greatly reduce the error caused by the first fixing clamp 2.

[0032] Preferably, the specific structure for synchronously moving the first limiting plate 8 and the second limiting plate 9 is as follows: a threaded rod 11 is rotatably connected to the connecting plate 10 via a bearing; a threaded hole 12 is provided on one side of the column 1; the threaded rod 11 is threadedly connected to the threaded hole 12; by rotating the threaded rod 11, the threaded rod 11 moves left and right relative to the column 1, thereby causing the first limiting plate 8 and the second limiting plate 9 to move left and right relative to the column 1. The first limiting plate 8 and the second limiting plate 9 move synchronously by rotating the threaded rod 11.

[0033] During the downward installation process, the pipe to be installed will experience relative displacement with the first limiting plate 8 and the second limiting plate 9, affecting the limiting effect of the pipe. To solve this problem, both the first limiting plate 8 and the second limiting plate 9 are slidably connected to the side away from the column 1 with a fitting plate 13. A suction cup 14 is fixedly connected to the side of the fitting plate 13 away from the column 1, so that when the second fixing clamp 3 moves the pipe to be installed downward, it simultaneously moves the fitting plate 13 downward, causing relative displacement between the pipe to be installed and the second limiting plate 9. During the downward installation process, the positions of the first limiting plate 8 and the second limiting plate 9 will not change, and the fitting plate 13 moves downward synchronously, without affecting the limiting effect of the pipe to be installed.

[0034] Although a positioning structure is used to limit the center axis of the fixed pipe and the pipe to be installed, a slight misalignment occurs between the pipe to be installed and the fixed pipe after the second fixing clamp 3 moves the pipe to be installed downwards. To solve this problem, such as... Figure 3 As shown, a positioning block 4 is fixedly connected to the top of the first fixing clamp 2, and a positioning hole 5 is provided on the top of the positioning block 4. A positioning rod 6 is fixedly connected to the bottom of the second fixing clamp 3, so that the positioning rod 6 matches the positioning hole 5 and the positioning rod 6 is inserted into the positioning hole 5. As the second fixing clamp 3 moves the pipe to be installed downwards, the positioning rod 6 is inserted into the positioning hole 5, and the positioning rod 6 slides downwards inside the positioning hole 5 until the bottom of the pipe to be installed contacts the top of the fixing pipe.

[0035] The top of the positioning hole 5 is provided with a guide groove 7, and the top diameter of the guide groove 7 is larger than its bottom diameter; The depth of the positioning hole 5 is greater than the length of the positioning rod 6.

[0036] Multiple universal ball bearings are fixedly installed on the inner wall of the guide groove 7. During the downward movement of the positioning rod 6, the downward movement path of the positioning rod 6 is corrected under the guidance of the universal ball bearings.

[0037] As the second fixing clamp 3 moves the pipe to be installed downwards, the positioning rod 6 is first inserted into the guide groove 7, and then into the positioning hole 5. During this process, the universal ball guides the positioning rod 6 and corrects its position, thereby correcting the left and right offset of the pipe to be installed. This ensures that when the second fixing clamp 3 moves the pipe to be installed downwards, the central axes of the two pipes are on the same straight line, and the two pipes can be aligned when they are in contact.

[0038] For pipes that are large in size or heavy in weight, the bottom of the column 1 is provided with a base 15, and the bottom of the column 1 and the base 15 are rotatably connected by a rotating shaft, so that the column 1 can rotate relative to the horizontal plane, and the column 1 and the base 15 are fixedly connected by bolts. First, rotate the column 1 so that the column 1 is parallel to the ground, which makes it easier to clamp and fix the pipe to be installed by the second fixing clamp 3, and also makes it easier to attach the second bonding plate 13 to the pipe to be installed. Then, rotate the column 1 so that the column 1 is perpendicular to the ground.

[0039] The following describes a method for assisting in the installation of pipes in prefabricated modular buildings, based on the aforementioned auxiliary device for pipe installation. The method includes the following steps: setting the pipe to be installed parallel to the column 1 and clamping it in place with the second fixing clamp 3. Move the column 1, which clamps the pipe to be installed, to the side of the fixed pipe, and clamp the fixed pipe with the first fixing clamp 2. This causes the second fixing clamp 3 to move the pipe to be installed down until it matches the fixed pipe.

[0040] During the process of moving the column 1, which clamps the pipe to be installed, to the side of the fixed pipe, the positioning structure ensures that the central axis of the fixed pipe and the central axis of the pipe to be installed are on the same straight line.

[0041] During the downward movement of the pipe to be installed by the second fixing clamp 3, the corresponding limiting structures on the second fixing clamp 3 and the first fixing clamp 2 limit the downward movement path of the pipe to be installed.

[0042] The installation assistance method provided by this invention moves the column clamping the pipe to be installed to the side of the fixed pipe, and clamps the fixed pipe with the first fixing clamp; the second fixing clamp drives the pipe to be installed to move down until it matches the fixed pipe to complete the pipe installation, and the positioning structure makes the central axis of the fixed pipe and the central axis of the pipe to be installed on the same straight line, which can quickly align the pipe to be installed with the fixed pipe, and is not affected by the pipe diameter and the fixing clamp structure.

[0043] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
