Description

Technical Field

[0001] The present application relates to the field of pipeline engineering construction and maintenance, and in particular to a pipeline elevation adjustment auxiliary device. Background Art

[0002] During subway construction, the construction of internal pipelines is very important, so during construction, the requirements for the pipeline axis elevation are very strict. Therefore, when installing pipelines, elevation adjusters are usually used to adjust the elevation of the pipelines during installation.

[0003] A related height adjuster includes a support device with a base at one end and an arc-shaped support at the other end, away from the base. During subway pipeline construction, the required pipeline installation height is first measured. A height adjuster of appropriate specifications is then selected. The base is placed on a relatively flat surface, and the pipeline is secured on the arc-shaped support. Installation can then proceed.

[0004] However, during pipeline installation, gravity or other factors often cause some parts of the installation process to not meet the required elevation, causing problems with the overall installation elevation of the pipeline. In this case, height adjustment is impossible, which in turn affects the stability and safety of the pipeline. Utility Model Content

[0005] In order to reduce the problem of overall error in pipeline elevation but inability to adjust the height, the present application provides a pipeline elevation adjustment auxiliary device.

[0006] This application provides a pipeline elevation adjustment auxiliary device, which adopts the following technical solutions:

[0007] A pipeline elevation adjustment auxiliary device, comprising:

[0008] A support column, the support column is set on the ground, and the support column is vertically provided with a sliding cavity;

[0009] a lifting column, the lifting column being slidably disposed in the sliding cavity via a height adjustment assembly;

[0010] The height adjustment assembly comprises:

[0011] A fixing member, which is sleeved on the outside of the support column and is used to fix the lifting column;

[0012] An operating member is rotatably disposed on the fixing member and is used to drive the lifting column to slide.

[0013] By adopting the above technical solution, the setting of the support column and the sliding cavity can support the lifting movement of the lifting column. The setting of the fixing part can adjust the operating part to abut or disengage with the lifting column, so that the operating part controls the lifting column to rise or fall, thereby reducing the overall error in the elevation of the pipeline, but the problem of being unable to adjust the height.

[0014] Optionally, the fixing member includes:

[0015] An adjusting block, wherein the adjusting block is sleeved on the outside of the supporting column, and one end of the adjusting block is rotatably connected to the supporting column via a rotating shaft;

[0016] A fixing rod is rotatably arranged on an end of the adjusting block away from the rotating shaft.

[0017] By adopting the above technical solution, the arrangement of the adjusting block and the fixing rod enables, when the fixing rod is pulled in a direction away from the lifting column, the operating member contacts the lifting column, thereby adjusting the lifting column to rise or fall; when the fixing rod is pulled in a direction close to the lifting column, the operating member disengages from the lifting column, and the lifting column descends under the action of gravity, thereby realizing the lifting or lowering of the lifting column conveniently and quickly.

[0018] Optionally, a groove is vertically provided on a side of the support column away from the fixing rod, and the operating member includes:

[0019] a guide wheel, the guide wheel being rotatably arranged on a side of the adjustment block away from the fixing rod;

[0020] A rack, the rack being fixedly arranged on a side of the lifting column close to the guide wheel;

[0021] an operating handle, the operating handle being fixedly arranged on a side of the guide wheel away from the rack;

[0022] Wherein, a spiral guide plate is provided at one end of the guide wheel close to the rack, the spiral guide plate is engaged with the rack, and the rotation axis of the guide wheel is perpendicular to the axis of the support column.

[0023] By adopting the above technical solution, since the operating handle and the guide wheel are fixedly arranged, when the operating handle is rotated, the guide wheel rotates along with the rotation of the operating handle, and the spiral guide plate is arranged on the guide wheel, and the spiral guide plate engages with the rack through a groove. Therefore, when the guide wheel rotates, it drives the spiral guide plate to rotate, and then the spiral guide plate drives the rack to perform linear motion, wherein the running track of the rack is perpendicular to the ground, so as to reduce the phenomenon that the auxiliary device cannot be height adjusted when there is an error in the pipeline elevation.

[0024] Optionally, a pipe bracket is fixedly provided on one end of the lifting column away from the supporting column.

[0025] By adopting the above technical solution, when the lifting column is adjusted to the elevation position, the pipe support is used to support the pipe to be installed, which facilitates the subsequent installation of the pipe.

[0026] Optionally, a tube cover is buckled on the upper end of the tube support, and the tube cover is fixedly connected to the tube support via a positioning piece.

[0027] By adopting the above technical solution, after the pipe support supports the pipe to be installed, the setting of the pipe cover can further limit the range of movement of the pipe, reduce the shaking amplitude of the pipe during the installation process, and better stabilize the pipe.

[0028] Optionally, positioning holes are provided at both ends of the tube support and the tube cover in one-to-one correspondence, and the positioning member is a threaded column, which passes through the positioning holes of the tube cover and the tube support in sequence, and the threaded column is threadedly connected to the positioning holes.

[0029] By adopting the above technical solution, the setting of the positioning holes and the threaded columns can connect the pipe cover and the pipe support, further limiting the activity space of the pipe, increasing the stability of the pipe during installation, and preventing the pipe from falling.

[0030] Optionally, a base plate is provided at the lower end of the support column, and a universal wheel is fixedly provided at the lower end of the base plate.

[0031] By adopting the above technical solution, the arrangement of the base plate and the universal wheels is used to move the auxiliary device to the installation position, thereby improving the convenience of the auxiliary device.

[0032] Optionally, an anti-slip pad is fixedly provided on the ends of the pipe cover and the pipe support that are in contact with the pipe.

[0033] By adopting the above technical solution, the provision of the anti-slip pad is used to increase the friction between the pipe cover, the pipe support and the pipe, thereby reducing the movement of the pipe during the installation process.

[0034] Optionally, a guide column is provided at the upper end of the base plate, a threaded hole is provided at the lower end of the support column, and the support column is threadedly connected to the guide column.

[0035] By adopting the above technical solution, the arrangement of the guide columns and the threaded holes facilitates the fixing and disassembly between the base plate and the support columns.

[0036] In summary, the present invention provides a pipeline elevation adjustment auxiliary device, which has at least one of the following beneficial technical effects:

[0037] 1. The setting of the support column and the sliding cavity can support the lifting movement of the lifting column. The setting of the fixing part can adjust the operating part to abut or disengage with the lifting column, so that the operating part controls the lifting column to rise or fall, thereby reducing the overall error in the elevation of the pipeline, but the problem of being unable to adjust the height.

[0038] 2. The arrangement of the adjustment block and the fixed rod ensures that when the fixed rod is pulled away from the lifting column, the operating member contacts the lifting column, thereby adjusting the lifting column to rise or fall. When the fixed rod is pulled toward the lifting column, the operating member disengages from the lifting column, and the lifting column descends under the action of gravity, thereby realizing the lifting or lowering of the lifting column conveniently and quickly.

[0044] The following is combined with Figure 1-3 This application is described in further detail.

[0045] Combine Figure 1 and Figure 2 The present application discloses an auxiliary device for adjusting the elevation of a pipeline, comprising a support column 11, a lifting column 12, and a height adjustment assembly 2. The support column 11 is mounted on the ground and has a vertically disposed sliding cavity 14. A vertical groove 10 is disposed on the side of the support column 11 away from the fixing rod 212. The lifting column 12 is slidably disposed within the sliding cavity 14 via the height adjustment assembly 2. The height adjustment assembly 2 includes a fixing member 21 and an operating member 22. The fixing member 21 is sleeved on the outside of the support column 11 and is used to fix the lifting column 12. The operating member 22 is rotatably disposed on the fixing member 21 and is used to drive the lifting column 12 to slide.

[0046] In the embodiment of the present application, both the support column 11 and the lifting column 12 are rectangular in shape, and the sliding cavity 14 is also rectangular in shape. It should be noted that the diameter of the lifting column 12 is sufficient to slide within the sliding cavity 14. The configuration of the groove 10 allows the lifting column 12 to abut against the operating member 22, thereby enabling the operating member 22 to control the raising and lowering of the lifting column 12.

[0047] During use, the fixing member 21 is pulled toward the end away from the lifting column 12, causing the operating member 22 to abut against the lifting column 12. Rotating the operating member 22 adjusts the height of the lifting column 12, bringing the lifting column 12 to the correct elevation of the pipeline. When the pipeline is no longer needed for support, the fixing member 21 is pulled toward the end closer to the lifting column 12, disengaging the operating member 22 and allowing the lifting column 12 to descend to its initial position. This reduces the problem of errors in the overall elevation of the pipeline, while preventing height adjustment.

[0048] Specifically, the fixing member 21 includes an adjustment block 211 and a fixing rod 212. The adjustment block 211 is sleeved on the outside of the support column 11. One end of the adjustment block 211 is rotatably connected to the support column 11 via a rotating shaft 15. The fixing rod 212 is rotatably disposed at the end of the adjustment block 211 away from the rotating shaft 15. The operating member 22 includes a guide wheel 221, a rack 222, and an operating handle 223. The guide wheel 221 is rotatably disposed on the side of the adjustment block 211 away from the fixing rod 212. The rack 222 is fixedly disposed on the side of the lifting column 12 near the guide wheel 221. The operating handle 223 is fixedly disposed on the side of the guide wheel 221 away from the rack 222. A spiral guide plate 13 is disposed on the end of the guide wheel 221 near the rack 222. The spiral guide plate 13 meshes with the rack 222. The rotation axis of the guide wheel 221 is perpendicular to the axis of the support column 11.

[0049] In the embodiment of the present application, the fixed rod 212 moves in a circular motion with the end of the adjustment block 211 away from the rotating shaft 15 as the center and the fixed rod 212's own length as the radius. This allows the fixed rod 212 to be adjusted upward or downward, thereby achieving abutment and disengagement between the operating member 22 and the lifting column 12. The width of the thread on the spiral guide plate 13 is sufficient to fit between two adjacent teeth of the rack 222, thereby allowing the spiral guide plate 13 and the rack 222 to mesh. When the spiral guide plate 13 rotates, it can drive the rack 222 to move linearly, thereby achieving the raising and lowering of the lifting column 12.

[0050] During operation, the fixed rod 212 is pulled toward the end away from the lifting column 12, causing the guide wheel 221 to engage with the rack 222. The guide wheel 221 is rotated, causing the rack 222 to move linearly, thereby raising or lowering the lifting column 12. Once the lifting column 12 is adjusted to the desired height, the operating handle 223 is released. When pipe support is no longer needed, the fixed rod 212 is pulled toward the end closer to the lifting column 12, causing the guide wheel 221 to move away from the rack 222, and the lifting column 12 to descend under the action of gravity.

[0051] Specifically, a pipe support 3 is fixedly mounted on the end of the lifting column 12 away from the support column 11. A pipe cover 4 is fastened to the upper end of the pipe support 3 and fixedly connected to the pipe support 3 via a positioning member 5. Both the pipe cover 4 and the end of the pipe support 3 that contacts the pipe are fixedly mounted with anti-slip pads. Positioning holes 6 are provided at both ends of the pipe support 3 and the pipe cover 4, respectively. The positioning member 5 is a single threaded column that passes through the positioning holes 6 of the pipe cover 4 and the pipe support 3 in sequence, and is threadedly connected to the positioning holes 6.

[0052] In the embodiment of the present application, the size, shape, and material of the pipe holder 3 and the pipe cover 4 are identical. The shape of the pipe holder 3 and the pipe cover 4 are both semi-arc-shaped, which can better fit the shape of the pipeline and play a role in stabilizing the pipeline. The material of the pipe holder 3 and the pipe cover 4 is rigid material, which increases the load-bearing capacity. The provision of an anti-slip pad can increase the friction between the pipe cover 4, the pipe holder 3, and the pipeline, and better play the role of fixing the pipeline. Positioning holes 6 are provided at both ends of the pipe holder 3 and the pipe cover 4. It should be noted that the number, position, and size of the positioning holes 6 on the pipe holder 3 and the pipe cover 4 are correspondingly set.

[0053] During use, the pipe to be installed is placed horizontally on the pipe support 3, that is, the axis of the pipe is aligned with the axis of the pipe support 3. The pipe cover 4 is buckled onto the pipe, and the threaded stud is passed through the positioning holes 6 of the pipe cover 4 and the pipe support 3 in sequence, and the pipe cover 4 and the pipe support 3 are fixed, thereby improving the stability of the pipe placement.

[0054] Specifically, the lower end of the support column 11 is provided with a base plate 7, and the lower end of the base plate 7 is fixedly provided with a universal wheel 8. The upper end of the base plate 7 is provided with a guide column 9, and the lower end of the support column 11 is provided with a threaded hole 16, and the support column 11 is threadedly connected to the guide column 9.

[0055] In the embodiment of the present application, the base plate 7 is square, the guide post 9 is cylindrical, and the surface of the guide post 9 is provided with threads for fixing the guide post 9 to the support post 11. Four universal wheels 8 are provided, fixed at four right angles on the side of the base plate 7 close to the ground, to enable the auxiliary device to move on the ground and enhance the convenience of use.

[0056] During use, the guide column 9 is placed in the threaded hole 16 of the support column 11 for quick positioning, and the support column 11 is then rotated to fix the base plate 7 and the support column 11, thereby increasing stability. The provision of the universal wheel 8 allows the auxiliary device to be moved to the target position according to the installation requirements, which is convenient and quick.

[0057] The implementation principle of the present embodiment is as follows: First, guide column 9 is positioned within threaded hole 16 of support column 11. Support column 11 is then rotated to secure base plate 7 and support column 11. The auxiliary device is then moved to the installation position using universal wheel 8. The pipeline elevation data is then determined based on the installation requirements. The fixing rod 212 is pulled toward the end away from the lifting column 12. The guide wheel 221 engages with the rack 222. The guide wheel 221 is rotated, causing the guide wheel 221 to drive the rack 222 in linear motion, thereby raising or lowering the lifting column 12. Once the lifting column 12 is adjusted to the desired elevation, the operating handle 223 is released. The pipeline to be installed is then placed horizontally on the pipe support 3, with the axis of the pipeline aligned with the axis of the pipe support 3. The pipe cover 4 is then snapped onto the corresponding portion of the pipeline. The threaded column is then inserted through the positioning holes 6 of the pipe cover 4 and the pipe support 3, and the pipe cover 4 and the pipe support 3 are secured. Pipe installation can then begin.

[0058] When the pipe support is no longer needed, the threaded stud is unscrewed from the positioning hole 6 of the pipe cover 4 and the pipe bracket 3, the pipe cover 4 fastened to the pipe is removed, and the fixing rod 212 is pulled toward the end closest to the lifting column 12. The guide wheel 221 moves away from the rack 222, and the lifting column 12 descends under the action of gravity. The auxiliary device is pushed and moved to the storage area via the universal wheels 8.

[0059] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
