Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline support technology, and in particular to a pipeline support frame for water conservancy and hydropower construction. Background Technology

[0002] Water conservancy projects require pipelines to transport water during the water conveyance process. Pipeline supports are the frames used for pipeline installation and support, mainly for the installation and fixing of pipelines.

[0003] Because the ground conditions are varied during pipe installation, it is necessary to level the two pipes to ensure that the two adjacent pipes are in a horizontal state. For smaller pipes, which are lighter in weight, leveling can also be done by personnel.

[0004] When dealing with large-diameter, heavy pipes, the difficulty and uncertainty of manual leveling increase significantly. These types of pipes often require specialized hoisting equipment for handling and positioning, and the leveling work is even more complex. Manual leveling is not only inefficient, but may also cause the pipe to sway or shift during the leveling process due to uneven force distribution and complex ground conditions, further increasing the risk of connection deviation. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0006] A pipe support frame for water conservancy and hydropower construction includes a base, the inner cavity of the upper end of the base is engaged with the outer wall of the lifting plate, the inner cavity of the lifting plate is threadedly connected to the outer wall of the lifting and fixing mechanism, and the upper end of the lifting plate is fixedly connected to the pipe fixing mechanism.

[0007] The lifting and fixing mechanism includes a rotating shaft, a first bevel gear, a second screw, a sliding groove, a fixed rod, a third screw, and a pushing block. The outer wall of the rotating shaft is rotatably connected to one end of the base. One end of the first bevel gear is fixedly connected to one end of the rotating shaft. The outer wall of the lower end of the second screw is rotatably connected to the inner cavity of the upper end of the base. The outer wall of the upper end of the second screw is threadedly connected to the inner cavity of the lifting plate. The upper end of the second bevel gear is fixedly connected to the lower end of the second screw, and one end of the second bevel gear meshes with one end of the first bevel gear. The sliding groove is formed in the inner cavity of the rotating shaft. The outer wall of the fixed rod is engaged with the inner cavity of the sliding groove, and the opposite ends of the fixed rod are engaged with a through hole at one end of the rotating shaft. The outer wall of the third screw is threadedly connected to the inner cavity of the rotating shaft. One end of the pushing block is fixedly connected to one end of the third screw.

[0008] As an improvement to the above technical solution, one end of the push block is tapered, and a ball bearing is installed on the outer wall of one end of the push block.

[0009] As an improvement to the above technical solution, the lifting and fixing mechanism includes springs, with one end of the springs that is far apart from each other being fixedly connected to one end of the springs that is far apart from each other in the inner cavity of the slide groove, and the other end of the springs that is close to each other being fixedly connected to one end of the fixing rod that is close to each other.

[0010] As an improvement to the above technical solution, the inner wall of the base is threaded with a support mechanism;

[0011] The support mechanism includes a first screw, a stabilizing plate, and a balance bar. The outer wall of the first screw is threadedly connected to the inner wall of the base. The upper end of the stabilizing plate is rotatably connected to the lower end of the first screw, and a piercing rod is installed on the lower end face of the stabilizing plate. The outer wall of the balance bar is engaged with the inner cavity of the base, and the lower end of the balance bar is fixedly connected to the upper end face of the stabilizing plate.

[0012] As an improvement to the above technical solution, the pipe fixing mechanism includes a support plate, a fourth screw, and a clamping plate. The lower end of the support plate is fixedly connected to the upper end of the lifting plate. The outer wall of the fourth screw is threadedly connected to the inner wall of the upper end of the support plate. The upper end of the clamping plate is rotatably connected to the lower end of the fourth screw. A limit rod is installed on the upper end of the clamping plate, and the outer wall of the limit rod is engaged with the inner cavity of the upper end of the support plate.

[0013] As an improvement to the above technical solution, a cushioning pad is installed at the lower end of the inner wall of the support plate, and a cushioning pad is installed at the lower end of the clamping plate.

[0014] The beneficial effects of this utility model are:

[0015] Rotating the shaft causes the first bevel gear to rotate, which in turn causes the second bevel gear and the second screw to rotate, thereby driving the lifting plate and the pipe fixing mechanism to move up and down, which in turn drives the pipe to move up and down, thus horizontally connecting adjacent pipes. Then, rotating the third screw causes the push block to move to one side and contact the fixing rod. As the push block continues to move to one side, the fixing rod moves away from the shaft and engages with the inner cavity on one side of the base, thus fixing the shaft and preventing the second screw from reversing due to gravity. This increases the stability of pipe leveling, facilitates pipe leveling by personnel, and ensures the accuracy of connecting adjacent pipes. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a pipe support frame for water conservancy and hydropower construction, including a base 1, the inner cavity of the upper end of the base 1 is engaged with the outer wall of the lifting plate 3, the inner cavity of the lifting plate 3 is threadedly connected to the outer wall of the lifting fixing mechanism 4, and the upper end of the lifting plate 3 is fixedly connected to the pipe fixing mechanism 5.

[0024] The lifting and fixing mechanism 4 includes a rotating shaft 41, a first bevel gear 42, a second screw 43, a second bevel gear 44, a slide groove 45, a fixing rod 47, a third screw 48, and a pushing block 49. The outer wall of the rotating shaft 41 is rotatably connected to one end of the base 1. One end of the first bevel gear 42 is fixedly connected to one end of the rotating shaft 41. The outer wall of the lower end of the second screw 43 is rotatably connected to the inner cavity of the upper end of the base 1. The outer wall of the upper end of the second screw 43 is threadedly connected to the inner cavity of the lifting plate 3. The upper end of the bevel gear 44 is fixedly connected to the lower end of the second screw 43, and one end of the second bevel gear 44 is meshed with one end of the first bevel gear 42. The slide groove 45 is opened in the inner cavity of the rotating shaft 41. The outer wall of the fixing rod 47 is engaged with the inner cavity of the slide groove 45, and the ends of the fixing rod 47 that are far apart from each other are engaged with the through hole at one end of the rotating shaft 41. The outer wall of the third screw 48 is threadedly connected to the inner cavity of the rotating shaft 41. One end of the pushing block 49 is fixedly connected to one end of the third screw 48.

[0025] Rotating the shaft 41 causes the first bevel gear 42 to rotate, which in turn causes the second bevel gear 44 and the second screw 43 to rotate, thereby driving the lifting plate 3 and the pipe fixing mechanism 5 to move up and down, and in turn driving the pipe to move up and down, thus horizontally connecting adjacent pipes. Then, rotating the third screw 48 causes the pushing block 49 to move to one side and contact the fixing rod 47. When the pushing block 49 continues to move to one side, the fixing rod 47 moves away from the shaft 41 and engages with the inner cavity on one side of the base 1, thereby fixing the shaft 41 and preventing the second screw 43 from reversing due to gravity. This increases the stability of pipe leveling, facilitates pipe leveling by personnel, and ensures the accuracy of connecting adjacent pipes.

[0026] Specifically, one end of the push block 49 is conical, and a ball bearing is installed on the outer wall of one end of the push block 49.

[0027] The friction generated when the push block 49 contacts the fixed rod 47 by the ball bearing installed on the surface of the push block 49 can be reduced, thus making it easier for personnel to rotate the shaft 41. Moreover, one end of the push block 49 is tapered, making it easier for the push block 49 to push the fixed rod 47.

[0028] Specifically, the lifting and fixing mechanism 4 includes a spring 46. The ends of the springs 46 that are far apart from each other are fixedly connected to the ends of the slide groove 45 that are far apart from each other, and the ends of the springs 46 that are close to each other are fixedly connected to the ends of the fixing rod 47 that are close to each other.

[0029] When the rotating shaft 41 needs to be rotated, the third screw 48 reverses to move the push block 49 to the left, thereby causing the push block 49 to lose contact with the fixed rod 47. The spring force of the spring 46 is used to bring the fixed rods 47 closer together, causing the fixed rods 47 to lose their fixation to the rotating shaft 41, thus increasing its automaticity.

[0030] Specifically, the inner wall of the base 1 is threaded with a support mechanism 2;

[0031] The support mechanism 2 includes a first screw 21, a stabilizing plate 22, and a balance bar 23. The outer wall of the first screw 21 is threadedly connected to the inner wall of the base 1. The upper end of the stabilizing plate 22 is rotatably connected to the lower end of the first screw 21, and a piercing rod is installed on the lower end face of the stabilizing plate 22. The outer wall of the balance bar 23 is snapped into the inner cavity of the base 1, and the lower end of the balance bar 23 is fixedly connected to the upper end face of the stabilizing plate 22.

[0032] By rotating the first screw 21, the stabilizing plate 22 moves downward under the limit of the balance bar 23. The first screw 21, the stabilizing plate 22 and the balance bar 23 are four groups, and each group can move up and down independently, so that the support mechanism 2 can adapt to different terrains and provide better support for the base 1.

[0033] Specifically, the pipe fixing mechanism 5 includes a support plate 51, a fourth screw 52, ​​and a clamping plate 53. The lower end of the support plate 51 is fixedly connected to the upper end of the lifting plate 3. The outer wall of the fourth screw 52 is threadedly connected to the inner wall of the upper end of the support plate 51. The upper end of the clamping plate 53 is rotatably connected to the lower end of the fourth screw 52. A limit rod is installed on the upper end of the clamping plate 53, and the outer wall of the limit rod is engaged with the inner cavity of the upper end of the support plate 51.

[0034] By rotating the fourth screw 52, ​​the clamping plate 53 can be moved up and down, thereby allowing the support plate 51 to fix pipes of different sizes, thus increasing the flexibility of the device in supporting the pipes.

[0035] Specifically, a cushioning pad is installed at the lower end of the inner wall of the support plate 51, and a cushioning pad is installed at the lower end of the clamping plate 53.

[0036] The installed cushioning pads can be used to softly clamp and fix the pipes, further protecting them.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
