Description

Technical Field

[0001] The present application relates to the field of pipeline installation auxiliary equipment, and in particular to a pipeline installation bracket device. Background Art

[0002] Indoor piping installations are often performed at a relatively high altitude, requiring the pipes to be hoisted to a higher level before connecting the two sections. To facilitate the lifting and position adjustment of the pipes indoors, a bracket device is required to stably lift and adjust the pipes.

[0003] For example, there is a liftable bracket for pipe prefabrication with announcement number CN205290268U. The pipe is placed on the bracket, and then the lifting shaft is rotated. The bracket is raised by relying on the threaded connection between the lifting shaft and the lifting seat. When the pipe is raised to a suitable height, the threaded adjustment rod is rotated to move the bracket along the horizontal radial direction of the pipe to adjust the horizontal position of the pipe.

[0004] Regarding the related technologies mentioned above, the pipe to be installed sometimes has a corner pipe with a curved portion at one end. Therefore, before installing the pipe, the pipe to be installed needs to be rotated around its own axis close to the end of the installed pipe, so that the pipe to be installed is rotated to a suitable position away from the end of the installed pipe. The contact between the pipe and the bracket makes the pipe susceptible to greater friction during rotation, making it difficult to carry out the pipe installation work smoothly and quickly. Summary of the Invention

[0005] In order to carry out pipeline installation work smoothly and quickly, the present application provides a pipeline installation bracket device.

[0006] The present application provides a pipe mounting bracket device that adopts the following technical solution.

[0007] A pipe installation bracket device includes a bracket for placing the pipe to be installed, an upper seat for the bracket to move horizontally and radially along the pipe, and a height portion provided on the upper seat for adjusting the height of the bracket. The upper portion of the bracket is formed with an arc surface with the same axial direction as the axial direction of the pipe. A wheel mouth is opened around the axis of the arc surface at a position close to the arc surface. The wheel mouth is detachably connected and rotatably connected to a pipe wheel that is rollingly connected to the outer wall of the pipe. The axis of the pipe wheel and the axis of the arc surface are in the same direction.

[0008] By adopting the above technical solution, the pipe to be installed placed on the pipe wheel can be rotated according to the required installation state, so that when installing a pipe with a bent part, the pipe can be adjusted more conveniently, thereby speeding up the installation of the pipe.

[0009] Optionally, a frame groove is formed on the arc surface, and two wheel inner plates are provided on the inner wall of the frame groove. The two wheel inner plates correspond one to one to the two arc-shaped sides close to the arc surface, and there is a group of pipe wheels between each wheel inner plate and the adjacent arc surface.

[0010] By adopting the above technical solution, the length of the pipe wheel is not too long, so that the mechanism inside the bracket can be maintained, and the two sets of pipe wheels can support the pipeline better and more stably.

[0011] Optionally, the lower part of the bracket is rotatably connected to two sets of frame wheels that are rollingly connected to the upper seat, the bracket is fixedly connected to a bracket rack, the upper seat is rotatably connected to a seat gear that engages with the bracket rack, the outside of the upper seat is rotatably connected to a radial shift turntable that is coaxially fixedly connected to the seat gear, the upper seat is fixedly connected to a seat screw, a bracket waist groove is opened in the bracket for the seat screw to pass through, and the seat screw is threadedly connected to a seat inner nut.

[0012] By adopting the above technical solution, the bracket can move stably along the horizontal radial direction of the pipe to be installed, and the bracket and the upper seat can be separated by unscrewing the nut in the seat, so that they can be assembled when in use and disassembled when not in use, saving storage space.

[0013] Optionally, the height portion includes a movable tube connected to the upper seat, a plug tube inserted into the end of the movable tube away from the upper seat, a jack arranged in the plug tube and driving the movable tube to move, a movable tube waist groove opened in the movable tube along the moving direction of the movable tube, and a plug tube bolt threadedly connected to the plug tube and passed through the movable tube waist groove.

[0014] By adopting the above technical solution, the height of the pipe to be installed can be adjusted, and the insert pipe bolts can be removed, so that the insert pipe and the moving pipe can be separated to facilitate the maintenance and storage of the jack.

[0015] Optionally, a bottom plate is provided at the side of the height portion away from the upper seat, and limiting plates that can be mounted on the surrounding guardrails of the lifting vehicle are fitted on both opposite sides of the bottom plate perpendicular to the axis of the arc surface. Both the limiting plate and the bottom plate are provided with plate waist grooves, and a bottom plate member is provided between the two corresponding plate waist grooves of the limiting plate and the bottom plate to make the bottom plate and the limiting plate tightly attached to each other.

[0016] By adopting the above technical solution, the entire device is placed on a lifting vehicle, two limit plates are mounted on the side panels of the lifting vehicle, and then the limit plates and the bottom plate are connected, so that the pipe to be installed is placed on the bracket and the lifting vehicle is then lifted to a greater height. Even if there is a certain amount of shaking, the entire device is not likely to fall over.

[0017] Optionally, the upper seat includes a swivel seat for the bracket to move, a fixed seat connected to the height part and rotatably connected to the swivel seat, the swivel seat is coaxially fixedly connected to a swivel seat worm gear located inside the fixed seat, the fixed seat is rotatably connected to a fixed seat worm engaged with the swivel seat worm gear, and the fixed seat is externally rotatably connected to a rotating turntable coaxially fixedly connected to the fixed seat worm gear.

[0018] By adopting the above technical solution, the pipeline to be installed can be rotated in the horizontal plane after the height is adjusted, so that the end of the pipeline to be installed and the end of the installed pipeline can be better aligned, so that the pipeline installation work can be carried out quickly.

[0019] Optionally, the wheel mouth is arc-shaped and its axis is consistent with the axis of the arc surface. The pipe wheel includes a wheel body that is rollingly connected to the pipe to be installed, an axle that is coaxially connected to the wheel body, and the axle is slidingly connected to the arc-shaped inner wall of the wheel mouth. An adjustment mechanism that can control the spacing between the axles of the same group of pipe wheels is provided in the bracket.

[0020] By adopting the above technical solution, the distance between the two wheel bodies can be adjusted to a certain extent according to the diameter of the pipe to be installed, so that pipes of different specifications can be placed on the pipe wheel more stably.

[0021] Optionally, the adjustment mechanism includes an adjustment rod rotatably connected to the wheel axle, a vertical movement rod hinged to the adjustment rod, a screw barrel rotatably connected to the bracket and threadedly connected to the adjustment rod, a screw barrel worm gear coaxially fixedly connected to the screw barrel, a worm in the frame rotatably connected to the bracket and meshed with the screw barrel worm gear, and a pipe diameter turntable rotatably connected to the outside of the bracket and coaxially fixedly connected to the worm in the frame.

[0022] By adopting the above technical solution, the two pipe wheels in the same group can move synchronously while maintaining the same height, and it is less likely that the two rollers in the same group will have inconsistent heights, so that the pipe to be installed can be placed on the pipe wheel to maintain good stability.

[0023] Optionally, the bracket is rotatably connected to a clamping rod, which is provided with a rotation-limiting block that can fit against the outer wall of the pipe to be installed. A clamping rod worm gear is coaxially fixedly connected to the rotation point of the clamping rod, and the clamping rod worm gear is engaged with a side worm gear rotatably connected to the bracket. The outside of the bracket is rotatably connected to a rotation-limiting turntable coaxially fixedly connected to the side worm gear.

[0024] By adopting the above technical solution, when the pipe to be installed is rotated around the axis of one end of itself and adjusted to a suitable state, the rotation limit block is pressed tightly against the outer wall of the pipe to be installed, so that when the pipe is connected, the position of the pipe to be installed is not easily changed, and the pipe after installation is not easily changed, which helps to improve the quality of pipe installation.

[0025] Optionally, the limiting block is slidably connected to the clamping rod, the clamping rod is provided with a spring rod passing through the clamping rod, the spring rod is provided with a rod end block that can abut against the side of the clamping rod away from the limiting block at one end away from the limiting block, and the clamping rod is passed through a compression spring that forces the limiting block to move away from the clamping rod.

[0026] By adopting the above technical solution, when the rotation limit block is in contact with the surface of the pipe to be installed and the clamping rod continues to rotate, the compression spring is compressed, causing the spring rod and the rod end block to move. At this time, the rotation of the clamping rod can be stopped, so that the surface of the pipe to be installed is not easily subjected to the large pressure from the rotation limit block.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. When installing pipes with bent parts, it is also more convenient to adjust the pipes to speed up the installation of the pipes;

[0029] 2. According to the diameter of the pipe to be installed, the distance between the two wheels can be adjusted to a certain extent, so that pipes of different specifications can be placed on the pipe wheel more stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Reference Figure 1 The upper surfaces of the two opposite sides of the bottom plate 47 perpendicular to the axis of the arc surface 4 are both fitted with limit plates 48, and the part of the limit plate 48 away from the bottom plate 47 is approximately U-shaped, so that the limit plate 48 can be tightly fitted on the railing of the lifting vehicle in the vertical direction. Each limit plate 48 fitted with the surface of the bottom plate 47 is penetrated by two plate waist grooves 49, and the bottom plate 47 corresponding to each plate waist groove 49 of the limit plate 48 is also penetrated by a plate waist groove 49. The length direction of the plate waist groove 49 is the same as the axis direction of the arc surface 4. A bottom plate part 32 is provided between the two aligned plate waist grooves 49, and the bottom plate part 32 can be a combination of bolts and nuts, so that the limit plate 48 and the bottom plate 47 are tightly fitted, and the setting of the plate waist grooves 49 on the limit plate 48 and the bottom plate 47 makes it possible to make corresponding adjustments between the limit plate 48 and the bottom plate 47 when the distance between the two surrounding panels of different lifting vehicles changes.

[0040] Reference Figure 1The height portion 3 includes a plug 43 fixedly connected to the center of the upper surface of the bottom plate 47. The plug 43 is vertical and the horizontal cross-section of the plug 43 is U-shaped. The plug 43 is tightly connected with the movable tube 42 along the vertical direction. A pipe opening 17 is provided at the side of the vertical opening of the plug 43 corresponding to the bottom end of the movable tube 42. A jack 44 is installed in the plug 43. The jack 44 can be a manual hydraulic jack. The upper end of the power rod of the jack 44 abuts against the inside of the movable tube 42 so that the operator can operate the jack 44 through the pipe opening 17 to lift the movable tube 42. A group of moving tube waist grooves 45 are provided on the two vertical side surfaces relative to each other at the bottom of the moving tube 42. Two moving tube waist grooves 45 are provided in each group along the vertical direction. The length direction of the moving tube waist groove 45 is vertical. The side of the moving tube 42 where the moving tube waist groove 45 is provided is adjacent to the side of the moving tube 42 where the pipe mouth 17 is provided. The insert tube 43 is threadedly connected to a horizontal insert tube bolt 46 corresponding to each moving tube waist groove 45. The insert tube bolt 46 is passed through the corresponding moving tube waist groove 45, so that the moving tube 42 is not easily separated from the insert tube 43.

[0041] Reference Figure 1 and Figure 2 The upper seat 2 is fixedly connected to the upper end of the movable pipe 42. A seat gear 56 is rotatably connected to the center of the upper surface of the upper seat 2. A radial shifting disc 57 is rotatably connected to the vertical outer wall of the upper seat 2 and is coaxially fixed to the seat gear 56. The bottom surface of the upper seat 2 is fixedly connected to a bracket rack 55 that meshes with the seat gear 56. The length of the bracket rack 55 is perpendicular to the axis of the arc surface 4, allowing the bracket 1 to move horizontally and radially along the pipeline to be installed. The lower surface of the bracket 1 is rotatably connected to the four corners corresponding to the bracket wheels 54, which are rollingly connected to the upper surface of the upper seat 2.

[0042] Reference Figure 2 A frame groove 52 is provided inside the bracket 1 and passes through the arc surface 4. The bottom surface of the frame groove 52 is provided with two bracket waist grooves 59 that pass through the bottom surface of the bracket 1. The length direction of the bracket waist groove 59 is consistent with the length direction of the bracket rack 55. Two vertical seat screws 58 are fixedly connected to the upper surface of the upper seat 2. The two seat screws 58 are respectively arranged in the two bracket waist grooves 59. The seat screw 58 is located in the frame groove 52 and one end is threadedly connected to the seat inner nut 41, so that the bracket 1 is not easily separated from the upper seat 2 during movement.

[0043] Reference Figure 2Two wheel inner plates 53 are fixedly connected within the frame groove 52. The operator can tighten or loosen the seat inner nut 41 between the two wheel inner plates 53. The upper surfaces of the two wheel inner plates 53 are shaped like the curved surface 4. Each wheel inner plate 53 and the inner wall of the adjacent frame groove 52 are penetrated by a wheel opening 5. A pipe pulley 51 is rotatably connected between the two corresponding wheel openings 5 ​​on the inner wall of the wheel inner plate 53 and the inner wall of the frame groove 52. A set of pipe pulleys 51 is provided on opposite sides of the two wheel inner plates 53. Each set of pipe pulleys 51 has two pipe pulleys 51 of the same height. The pipe pulleys 51 are rotatably connected to the outer wall of the pipe to be installed, allowing the pipe to rotate around its own axis. Several wheel openings 5 ​​are evenly distributed around the axis of the curved surface 4, allowing the pipe pulleys 51 to be installed in different wheel openings 5 ​​according to pipe diameters.

[0044] The implementation principle of the pipe installation bracket device of the first embodiment of the present application is as follows: the bottom plate 47 is placed on the lifting vehicle, and then the limit plate 48 is mounted on the corresponding wall of the lifting vehicle, and the limit plate 48 and the bottom plate 47 are fastened using the bottom plate member 32. The movable pipe 42 is then mounted on the corresponding insertion pipe 43, and the insertion pipe bolt 46 is passed through the corresponding movable pipe waist groove 45 and threadedly connected to the insertion pipe 43. The bracket 1 is then placed on the upper base 2, so that the bracket waist groove 59 is mounted on the base screw 58, and the base inner nut 41 is then threadedly connected to the base screw 58 through the bracket groove 52.

[0045] Then the pipe to be installed is placed on the two sets of pipe wheels 51 of the bracket 1, and then the lifting vehicle moves the entire device and the pipe to be installed upward over a large range. When the pipe to be installed and the pipe to be connected are close in height, the lifting vehicle stops lifting, and the jack 44 is manually controlled to lift the pipe to be installed. When the pipe height adjustment is completed, the radial shift turntable 57 is rotated to move the pipe to be installed along the horizontal radial direction of one end placed on the bracket 1, so that the end of the pipe to be installed and the end of the pipe to be connected are aligned. Then, the pipe to be installed is rotated around the axis of the end of the pipe to be installed placed on the bracket 1, so that the curved part of the pipe to be installed is adjusted into place, and finally the connection and installation work between the pipes is carried out.

[0046] Example 2:

[0047] The second embodiment of the present application discloses a pipe mounting bracket device, referring to Figure 3The difference from the first embodiment is that the upper seat 2 includes a fixed seat 34 fixedly connected to the upper end of the movable tube 42. The upper surface of the fixed seat 34 is rotatably connected to the rotating seat 33. The rotating axis of the rotating seat 33 is vertical. A rotating seat worm gear 35 is rotatably connected to the fixed seat 34 and coaxially fixed to the rotating point of the rotating seat 33. A fixed seat worm 36 is rotatably connected to the fixed seat 34 and meshes with the rotating seat worm gear 35. A rotating turntable 37 is rotatably connected to the vertical outer wall of the fixed seat 34 near the radial displacement turntable 57, which is coaxially fixed to the fixed seat worm 36. This allows for corresponding adjustment when a small angle exists between the end of the pipe to be installed and the end of the pipe to be connected. Corresponding rollers or balls can be provided on the lower surface of the rotating seat 33, and corresponding tracks can be provided on the upper surface of the fixed seat 34 to ensure stable rotation of the rotating seat 33.

[0048] Reference Figure 4 The wheel mouth 5 is provided on the inner wall of the corresponding frame groove 52 and the wheel inner plate 53, and the wheel mouth 5 is in an arc shape with the axis and the axis of the arc surface 4 being the same. The pipe wheel 51 includes a wheel body 38 that is rollingly connected to the outer wall of the pipeline circumference. The wheel body 38 is coaxially connected to the wheel axle 39. The two ends of the wheel axle 39 are respectively slidably connected to the inner walls of two adjacent wheel mouths 5, so that the wheel body 38 can rotate around the axis of the arc surface 4. An adjusting mechanism 21 is provided in the bracket 1, which can control the spacing between the wheel axles 39 of the same group of pipe wheels 51. The adjusting mechanism 21 includes an adjusting rod 22 rotatably connected to the wheel axle 39. The two adjusting rods 22 corresponding to the two pipe wheels 51 in the same group are a group. The two adjusting rods 22 in the same group are hinged to the same vertical shift rod 23 at one end. The bottom end of the vertical shift rod 23 is threadedly connected to a vertical screw barrel 24. The bottom end of the screw barrel 24 is rotatably connected to the bottom surface of the frame groove 52. The outer circumference of the bottom end of the two screw barrels 24 is coaxially fixed with a screw barrel worm gear 25. Two internal worm gears 26 fixed with the same axis are rotatably connected in the frame groove 52. The two internal worm gears 26 are meshed with the two screw barrel worm gears 25 one by one. The vertical outer wall of the bracket 1 away from the radial shift disc 57 is rotatably connected to a pipe diameter disc 27 coaxially fixedly connected to the internal worm gear 26, so that the two pipe wheels 51 in the same group can be adjusted to the same height synchronously.

[0049] Reference Figure 5 The bracket 1 is rotatably connected to a clamping rod 28 at both ends of the arc surface 4. The direction of the clamping rod 28's rotation axis is the same as the direction of the arc surface 4's axis. The end surface of the clamping rod 28 away from the bracket 1 is slidably connected to a limited rotation block 29. The limited rotation block 29 can fit the upper portion of the circumferential outer wall of the pipe to be installed. The clamping rod 28's rotation point is coaxially fixedly connected to a clamping rod worm gear 11. The clamping rod worm gear 11 meshes with a horizontal side worm gear 12 that is rotatably connected to the inner wall of the bracket groove 52. The outer wall of the bracket 1 is rotatably connected to a limited rotation disk 13 that is coaxially fixedly connected to the side worm gear 12. After the pipe to be installed rotates around its own end axis and completes adjustment, the limited rotation block 29 can fit the outer wall of the pipe to prevent the pipe from rotating easily.

[0050] Reference Figure 5 The side of the rotation limit block 29 facing the clamping rod 28 is fixedly connected to a spring rod 14, and the spring rod 14 is passed through the clamping rod 28. The end of the spring rod 14 away from the rotation limit block 29 is fixedly connected to a rod end block 15. The rod end block 15 can abut against the side of the clamping rod 28 away from the rotation limit block 29. At the same time, the spring rod 14 is passed through a compression spring 16, whose two ends respectively abut against the clamping rod 28 and the rotation limit block 29. The compression spring 16 forces the rotation limit block 29 to move away from the clamping rod 28, so that when the rotation limit block 29 is pressed tightly against the pipe surface, the pipe surface is not easily subjected to large pressure.

[0051] The implementation principle of a pipe installation bracket device in the second embodiment of the present application is: rotating the rotating turntable 37 causes the pipe to be installed to rotate in the horizontal plane, so that adjustment can be performed when a small angle between two pipes is required.

[0052] By rotating the pipe diameter dial 27, the distance between two pipe wheels 51 in the same group can be adjusted, so that the height of the pipe wheels 51 can be changed to adapt to pipes with different diameters.

[0053] When the work of rotating the pipe to be installed along the axis of one end placed on the bracket 1 is adjusted to the right position, the rotation limit turntable 13 can be rotated to move the rotation limit block 29 toward the outer wall of the pipe until the rotation limit block 29 fits the pipe. At this time, the rotation of the clamping rod 28 is maintained to make the rod end block 15 away from the clamping rod 28, and then the rotation of the rotation limit turntable 13 is stopped.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
