Detailed Implementation

[0031] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figure 1 ,Figure 2 and Figure 7 As shown in the drawings, the variable-diameter adjustable pipeline support device comprises:

[0033] a base 10;

[0034] a support frame 12 movably mounted on the base 10, the support frame 12 having a platform 121 at the top thereof, and the support frame 12 being capable of moving up and down along the vertical direction;

[0035] a mounting plate 21 vertically fixed on the platform 121, the mounting plate 21 movably having an inner ring 22 embedded in the middle portion thereof, and a through hole 222 for a pipeline (not shown in the drawings) to pass through being provided in the middle portion of the inner ring 22, and two pressing rollers 30 being provided on the two sides of the mounting plate 21 respectively, one end of each pressing roller 30 being rotatably connected with the mounting plate 21, and the other end being movably connected with the inner ring 22, and the inner ring 22 being capable of driving each pressing roller 30 to rotate until each pressing roller 30 abuts against the pipeline, and each pressing roller 30 forming a parallelogram structure in the vertical plane.

[0036] Most of the existing pipeline support devices are designed for pipelines of specific materials, and can only support pipelines of specific sizes, and cannot adapt to pipelines of various diameters, and are difficult to adjust according to the actual situation on site, and setting up devices of multiple sizes will increase the cost; at the same time, most of these devices occupy a large space, have a complex structure, are inconvenient to store and transport, and are difficult to maintain and repair in the later period. In addition, the existing pipeline support devices have limited carrying capacity, and cannot meet the support requirements of some heavy pipelines, and are not convenient to use in complex pipeline networks.

[0037] Therefore, the utility model provides a variable-diameter adjustable pipeline support device, through the cooperation of the mounting plate 21, the inner ring 22 and each pressing roller 30, the pressing roller 30 is driven to rotate to stably clamp the pipeline, and the correct position of the pipeline is ensured; and by changing the rotation amplitude of the pressing roller 30, pipelines of various diameters can be clamped, and diversified pipeline requirements can be met; at the same time, the support frame 12 can move up and down according to actual needs, so that the clamping height is adjusted, and the utility is good. According to the specific length of the pipeline, the device of the utility model can be set up in multiple combinations for use, the supporting force is improved, the pipeline is stably supported, and the work risk is reduced.

[0038] Specifically, through the setting of the base 10 and the support frame 12, a stable foundation is provided for the support and clamping of the pipeline, and the up and down movement of the support frame 12 facilitates the adjustment of the specific clamping height, and the appropriate height position can be adjusted according to the actual use needs, so that the pipeline is better supported and clamped.

[0039] In actual use, the support frame 12 is adjusted to a suitable height, the pipeline to be supported is passed through the corresponding through hole 222 on the inner ring 22, the inner ring 22 is rotated, thereby driving the respective compression rollers 30 to rotate until the compression rollers 30 are tangent to the surface of the pipeline, at which time the pipeline is preferably coaxially arranged with the through hole 222.

[0040] The mounting plate 21 is preferably fixedly connected with the platform 121 (the support frame 12) through the support plate 28, and a reinforcing rib 29 is arranged at the back of the support plate 28, which is beneficial to the stability of the mounting plate 21, and facilitates the disassembly and assembly of the mounting plate 21, and different specifications of the mounting plate 21 can be replaced according to actual needs.

[0041] The two (a group) compression rollers 30 located on one side of the mounting plate 21 are symmetrically and parallel arranged on both sides of the pipeline to clamp the pipeline; the two (a group) compression rollers 30 on the other side of the mounting plate 21 are clamped to the pipeline in the same state, and it is worth mentioning that the two groups of compression rollers 30 on both sides of the mounting plate 21 clamp the pipeline in two directions, and actually four compression rollers 30 can be considered to form a parallelogram structure in a vertical plane, thereby realizing stable clamping of the pipeline.

[0042] As shown in Figure 4 and Figure 5 , preferably, a plurality of outer fixed columns 211 corresponding to the respective roller shafts 31 are uniformly distributed around the inner ring 22 on the mounting plate 21, and a plurality of inner fixed columns 221 corresponding to the respective roller shafts 31 are uniformly distributed on the inner ring 22.

[0043] In this embodiment, four outer fixed columns 211 and four inner fixed columns 221 are preferably arranged according to the number of compression rollers 30, and since the compression rollers 30 are actually arranged in two groups on both sides of the mounting plate 21, the outer fixed columns 211 and the inner fixed columns 221 are also arranged in two groups on both sides of the mounting plate 21 and on both sides of the inner ring 22.

[0044] Further, the roller shaft 31 is arranged to pass through the compression roller 30, and one end of the roller shaft 31 is rotatably connected with the corresponding outer fixed column 211, and the other end is rotatably connected with the corresponding inner fixed column 221 through the connecting rod 32.

[0045] The compression roller 30 is actually connected with the mounting plate 21 and the inner ring 22 through the roller shaft 31, in order to facilitate the rotation of the compression roller 30 with the inner ring 22, one end of the roller shaft 31 is rotatably connected with the outer fixed column 211, and the other end is rotatably connected with the inner fixed column 221 through the connecting rod 32, wherein the connecting rod 32 is rotatably connected with the roller shaft 31 and the inner fixed column 221.

[0046] In the initial state, the connecting rod 32 and the roller shaft 31 form a certain angle, when the inner ring 22 rotates, the connecting rod 32 drives the roller shaft 31 to rotate with the inner ring 22, at this time, the angle between the connecting rod 32 and the roller shaft 31 gradually increases, and the connecting rod 32 can be considered to increase the linear displacement of the roller shaft 31; at the same time, since the roller shaft 31 is rotatably connected with the outer fixed column 211, the connecting rod 32 also provides an additional degree of freedom for the roller shaft 31, so that the roller shaft 31 can rotate with the compression roller 30 to approach the pipe for clamping.

[0047] When the clamping work is completed, the inner ring 22 is rotated to drive the connecting rod 32 and the roller shaft 31 to return to the initial state.

[0048] Preferably, two bearings 33 are sleeved on each roller shaft 31, and the two bearings 33 are respectively embedded in the corresponding compression roller 30. The compression roller 30 is actually sleeved on the roller shaft 31, and the compression roller 30 is connected with the roller shaft 31 through the bearings 33, so that the compression roller 30 can rotate around its own axis. Such a structure facilitates the movement of the pipe in the axial direction when the pipe is clamped in the circumferential direction.

[0049] Therefore, the support device can also transport the pipe when supporting and clamping the pipe, realizing multiple applications of supporting, clamping and transporting the pipe, and having good use effect.

[0050] Further, the rocker 23 is fixedly installed on one side of the inner ring 22, and the limiting screw 24 corresponding to the rocker 23 is arranged on the mounting plate 21. The rocker 23 facilitates the rotation of the inner ring 22 by the operator, and when the supporting and clamping work is completed, the inner ring 22 is rotated to the initial position. Since each compression roller 30, roller shaft 31 and connecting rod 32 has a certain weight, the limiting screw 24 is arranged here to limit the relative position of the rocker 23, so as to control the compression roller 30, roller shaft 31 and connecting rod 32 and other components to be in the initial state.

[0051] Preferably, an arc-shaped groove 25 is formed around the outer circumferential side of the inner ring 22, and a guide column 26 corresponding to the arc-shaped groove 25 is respectively arranged on the two side walls of the mounting plate 21.

[0052] In the utility model, the cooperation between the arc-shaped groove 25 and the guide column 26 is used to realize the rotation of the inner ring 22 relative to the mounting plate 21. When the inner ring 22 rotates, the guide column 26 on the mounting plate 21 slides along the arc-shaped groove 25, providing a guide function for the rotation of the inner ring 22.

[0053] As Figure 5As shown, two arc-shaped grooves 25 are arranged in the preferred embodiment one, and the length of the arc-shaped grooves 25 can limit the sliding distance of the guide posts 26. When clamping pipes with different diameters, the rotating distance of the compression rollers 30 is different, that is, the rotating angle of the inner ring 22 is different, and the sliding distance of the guide posts 26 is different. Here, the length of the arc-shaped grooves 25 can meet the clamping requirements of most pipes.

[0054] As shown in the preferred embodiment one, Figure 6 As shown in the preferred embodiment two, the arc-shaped grooves 25 can be arranged as annular grooves around the inner ring 22, and two guide posts 26 can slide along the annular grooves. In actual work, considering the influence of the compression rollers 30, the clamped pipes and other structures, the actual rotating angle of the inner ring 22 is within a certain range, and the sliding distance of the guide posts 26 in the arc-shaped grooves 25 is also limited, but it does not affect the normal clamping of the pipes.

[0055] Further, a notch 212 is vertically arranged on the top of the mounting plate 21, a tightening handle 27 is arranged on the mounting plate 21 near the notch 212, and the tightening handle 27 horizontally crosses the notch 212.

[0056] The notch 212 on the top of the mounting plate 21 is actually communicated with the space where the inner ring 22 is located. By adjusting the tightening handle 27, the tightness between the mounting plate 21 and the inner ring 22 can be adjusted.

[0057] In actual work, when the inner ring 22 needs to be rotated, the tightening handle 27 can be loosened to facilitate the flexible rotation of the inner ring 22. After each compression roller 30 clamps a pipe, the tightening handle 27 is tightened. At this time, there is no relative movement between the guide post 26 and the corresponding arc-shaped groove 25, which ensures that the inner ring 22 and the mounting plate 21 are in a relatively tight state, thereby facilitating the stable clamping of the pipe.

[0058] As shown in the preferred embodiment one, Figures 1 to 3 As shown in the preferred embodiment two, the arc-shaped grooves 25 can be arranged as annular grooves around the inner ring 22, and two guide posts 26 can slide along the annular grooves. In actual work, considering the influence of the compression rollers 30, the clamped pipes and other structures, the actual rotating angle of the inner ring 22 is within a certain range, and the sliding distance of the guide posts 26 in the arc-shaped grooves 25 is also limited, but it does not affect the normal clamping of the pipes.

[0059] In the present example, the support frame 12 is connected to the base 10 through the sleeve 11, wherein the support frame 12 is embedded in the sleeve 11, and a worm gear mechanism is arranged in the sleeve 11 to drive the support frame 12 to move up and down. The support frame 12 actually moves up and down along the sleeve 11. Here, the hand wheel 16 is arranged outside the sleeve 11, and the worm gear mechanism is driven to work through the transmission rod 15, thereby realizing the up and down movement of the support frame 12.

[0060] The sleeve 11 provides support for the support frame 12, facilitates installation of the worm gear mechanism, and protects these parts from the external environment.

[0061] Further, the sleeve 11 is symmetrically provided with openings 111 on both sides, and a bottom plate 112 is arranged across between the two openings 111. The worm gear mechanism is fixed to the bottom plate 112. The openings 111 facilitate installation of the bottom plate 112, further facilitate installation of the worm gear mechanism, and facilitate up and down movement of the support frame 12.

[0062] Preferably, two installation grooves 113 are symmetrically provided on the sleeve 11, each installation groove 113 is covered with a cover plate 114, and the hand wheel 16 penetrates through one of the cover plates 114. Preferably, the installation grooves 113 are located on the sides adjacent to the openings 111, the two installation grooves 113 are oppositely arranged, the installation grooves 113 correspond to the worm gear mechanism, and the cover plates 114 are preferably arranged on the installation grooves 113 to facilitate the operator to open the cover plates 114 and maintain and repair the worm gear mechanism.

[0063] Further, a plurality of set screws 115 are arranged around the top of the sleeve 11. When the support frame 12 is moved to the appropriate position, the support frame 12 is locked by the set screws 115, further ensuring that the support frame 12 is in a stable state, which is conducive to stable clamping and supporting of the pipe.

[0064] It is worth mentioning that in the utility model, the pipe is clamped by rotating the pressure roller 30. In the clamped state, the axis of the pipe is in the same straight line as the axis of the through hole 222, that is, the pipe and the through hole 222 remain coaxial. When the pipe needs to be supported, clamped or conveyed at different heights, the height of the support frame 12 can be adjusted, which is convenient to adjust. When the working height is determined, if the pipe of other diameters needs to be replaced, the height does not need to be adjusted again, and the axis of the pipe always remains at the position of the axis of the through hole 222, thereby greatly improving the working efficiency.

[0065] The pipe supporting device has a reasonable structure. The installation plate 21, the inner ring 22 and the pressure rollers 30 are cooperatively arranged to drive the pressure rollers 30 to rotate and stably clamp the pipe, and ensure that the pipe is in the correct position. Changing the rotation amplitude of the pressure rollers 30 can clamp pipes of various diameters, meeting diversified pipe requirements. The support frame 12 can move up and down according to actual needs, thereby adjusting the clamping and supporting height, which is good in practicability. In addition, the pressure roller 30 is cooperatively arranged with the roller shaft 31 through the bearing 33, which facilitates rotation of the pressure roller 30 around itself, is conducive to continuous conveying of the pipe when the pipe is clamped and supported, and is convenient for actual use.

[0066] The preferred embodiments described herein are merely preferred embodiments of the utility model, but the protection scope of the utility model is not limited to this. The modification or supplement of the described specific embodiments or the adoption of similar ways of replacement by the person skilled in the art to which the utility model belongs should be covered in the protection scope of the utility model.
