Description

Technical Field

[0001] The present application relates to the technical field of pipeline fixing, and particularly relates to a fixing device for the internal pipelines of a cold box. Background Art

[0002] Inside the cold box, pipeline fixing is an important link. Existing pipeline fixing devices usually adopt simple structures such as metal clamps or plastic ties. Although these devices can play a certain role in fixing, in a low-temperature environment, due to the thermal expansion and contraction effect of materials, they often become loose or fail, posing a hidden danger to the normal operation of the cold box.

[0003] Currently, a common solution is to adopt an elastic metal clamp, and the elastic deformation of the clamp is used to adapt to the thermal expansion and contraction of the pipeline. However, after long-term use, the elasticity of this clamp gradually weakens, resulting in a decline in the fixing effect. Another solution is to use plastic ties. Although the cost is relatively low, the plastic is prone to becoming brittle at low temperatures, and the ties are prone to breaking, and there are also problems with unstable fixing. Utility Model Content

[0004] In order to improve the problems of unstable fixing, easy loosening or failure of the pipeline fixing device in a low-temperature environment, the present application provides a fixing device for the internal pipelines of a cold box.

[0005] The present application provides a fixing device for the internal pipelines of a cold box, including a mounting base and two fixture components arranged on the mounting base. An opening is provided on one outer wall of the mounting base, and a cover plate is fixedly connected to the inner wall of the opening. Four symmetrically arranged rectangular openings are provided on one outer wall of the cover plate. The two fixture components are slidably arranged in the four rectangular openings. The fixture component includes a connecting frame slidably connected to the inner walls of the two rectangular openings, and the same fixture seat is fixedly connected to the outer walls of the two connecting frames. An arc-shaped groove is provided on the bottom outer wall of the fixture seat, and an arc-shaped seat is arranged in the arc-shaped groove.

[0006] With the above structure, through the two adjustable fixture components on the mounting base, it is convenient to clamp and fix the pipelines in the cold box. The detachable cover plate is provided to facilitate the disassembly and maintenance of the parts in the mounting base. The connecting frame is provided to facilitate the installation and fixation of the arc-shaped seat, and the arc-shaped seat is provided to facilitate the pressing of the pipeline.

[0007] A connecting seat is fixedly connected to the top inner wall of the fixture seat, and a circular opening is provided on one outer wall of the connecting seat. A mounting rod is fixedly connected to the inner wall of the circular opening, and both ends of the mounting rod are fixedly connected to the inner wall of the fixture seat.

[0008] With the above structure, the adjustable arc-shaped seat on the fixture seat directly contacts the pipeline.

[0009] The outer wall of the installation rod is slidably connected with two symmetrically arranged sliding sleeves, and the outer walls of the two sliding sleeves are rotatably connected with connecting plates, and one end of the two connecting plates is rotatably connected to the arc-shaped seat.

[0010] With the above structure, by sliding the sliding sleeve on the installation rod, when the sliding sleeve moves, it directly drives the connecting plate to move.

[0011] The outer wall of the installation rod is slidably connected with two symmetrically arranged adjusting rings, and two springs are sleeved on the outer wall of the installation rod, and the springs are located between the adjusting rings and the sliding sleeves.

[0012] With the above structure, the arrangement of the adjusting ring facilitates sliding on the installation rod. When the adjusting ring moves towards the sliding sleeve, it directly adjusts the elastic force of the spring.

[0013] The two inner side walls of the fixture seat are rotatably connected with the same two-way screw rod II, and the outer wall of the two-way screw rod II is screwed with two symmetrically arranged adjusting plates, and the adjusting plates are fixedly connected to the adjusting rings. One outer wall of the fixture seat is rotatably connected with an adjusting knob, and one end of the adjusting knob is fixedly connected to the two-way screw rod II.

[0014] With the above structure, by driving the two-way screw rod II to rotate through the adjusting knob, when the two-way screw rod II rotates, it drives the two adjusting plates to move towards or away from each other. When the adjusting plates move, they directly adjust the position of the adjusting rings.

[0015] The two inner side walls of the installation seat are rotatably connected with the same two-way screw rod I, and the outer wall of the two-way screw rod I is screwed with two symmetrically arranged driving seats.

[0016] With the above structure, when the two-way screw rod I rotates, it directly adjusts the two driving seats to move towards or away from each other. When the driving seats move, they drive the fixture assembly to move.

[0017] The four connecting frames are respectively fixedly connected to the two driving seats. A partition is fixedly connected to the midline of the inner wall of the installation seat, and the two-way screw rod I passes through and is installed on the partition.

[0018] With the above structure, the arrangement of the partition facilitates the support of the two-way screw rod I and at the same time separates the two driving seats.

[0019] One outer wall of the installation seat is rotatably connected with a rotating part connected to the two-way screw rod I, and four symmetrically arranged round openings are formed in one outer wall of the installation seat.

[0020] With the above structure, the arrangement of the rotating part facilitates driving the two-way screw rod I to rotate, and the arrangement of the round openings facilitates the fixed installation of the installation seat.

[0021] To sum up, the beneficial effects of the present application are as follows:

[0022] 1. This application clamps the pipes inside the cold box by setting two fixture components on the mounting base. The cooperation between the adjustable arc plate, spring and sliding sleeve connecting plate in the clamping component facilitates the clamping of the pipes inside the cold box. Also, by setting the bidirectional screw two, adjusting plate and adjusting ring in the fixture base, it is convenient to adjust the spring force on the mounting rod, thus avoiding the problem that the arc plate cannot clamp the pipes due to the attenuation of the spring force.

[0023] 2. This application sets a bidirectional screw one in the mounting base. The setting of the bidirectional screw one facilitates directly driving the movement of two driving seats. When the two driving seats move, it is convenient to directly drive the two fixture components to press the pipes of the cold box, thereby avoiding excessive gaps between the two fixture components and loosening of the pipes of the cold box, and improving the stability of pipe clamping.

An opening is provided on the outer wall of one side of the mounting base 1, and a cover plate 4 is fixedly connected to the inner wall of the opening. Four symmetrically arranged rectangular openings 6 are provided on the outer wall of one side of the cover plate 4. Two fixture components 5 are slidably arranged in the four rectangular openings 6. The fixture component 5 includes a connecting frame 10 slidably connected to the inner walls of the two rectangular openings 6, and the outer walls of the two connecting frames 10 are fixedly connected to the same fixture base 11. An arc groove is provided on the bottom outer wall of the fixture base 11, and an arc seat 12 is arranged in the arc groove.

[0031] During use, two adjustable fixture components 5 on the mounting base 1 facilitate clamping and fixing the pipes in the cold box. The detachable cover plate 4 is provided to facilitate disassembly and maintenance of the parts in the mounting base 1. The connecting frame 10 is provided to facilitate the installation and fixing of the arc-shaped seat 12, and the arc-shaped seat 12 is provided to facilitate pressing the pipes.

[0032] Refer to Figure 4 , a connecting seat 14 is fixedly connected to the inner wall of the top of the fixture seat 11, and a circular opening is provided on the outer wall of one side of the connecting seat 14. An installation rod 15 is fixedly connected to the inner wall of the circular opening, and both ends of the installation rod 15 are fixedly connected to the inner wall of the fixture seat 11. The adjustable arc-shaped seat 12 on the fixture seat 11 is in direct contact with the pipe.

[0033] Refer to Figure 4 , two symmetrically arranged sliding sleeves 16 are slidably connected to the outer wall of the installation rod 15, and connecting plates 19 are rotatably connected to the outer walls of both sliding sleeves 16. One end of both connecting plates 19 is rotatably connected to the arc-shaped seat 12. When the sliding sleeve 16 slides on the installation rod 15, the sliding sleeve 16 directly drives the connecting plate 19 to move when it moves.

[0034] Refer to Figure 4 , two symmetrically arranged adjusting rings 18 are slidably connected to the outer wall of the installation rod 15. Two springs 17 are sleeved on the outer wall of the installation rod 15, and the springs 17 are located between the adjusting ring 18 and the sliding sleeve 16. The provision of the adjusting ring 18 facilitates sliding on the installation rod 15. When the adjusting ring 18 moves towards the sliding sleeve 16, the elastic force of the spring 17 is directly adjusted.

[0035] Refer to Figure 4 , the same two-way screw rod two 20 is rotatably connected to the inner walls of both sides of the fixture seat 11, and two symmetrically arranged adjusting plates 21 are screwed to the outer wall of the two-way screw rod two 20. The adjusting plate 21 is fixedly connected to the adjusting ring 18. An adjusting knob 13 is rotatably connected to the outer wall of one side of the fixture seat 11, and one end of the adjusting knob 13 is fixedly connected to the two-way screw rod two 20. When the adjusting knob 13 drives the two-way screw rod two 20 to rotate, the two-way screw rod two 20 drives the two adjusting plates 21 to move towards or away from each other. When the adjusting plate 21 moves, the position of the adjusting ring 18 is directly adjusted.

[0036] Refer to Figure 2 , the same two-way screw rod one 8 is rotatably connected to the inner walls of both sides of the mounting base 1, and two symmetrically arranged driving seats 9 are screwed to the outer wall of the two-way screw rod one 8. When the two-way screw rod one 8 rotates, it directly adjusts the two driving seats 9 to move towards or away from each other. When the driving seat 9 moves, it drives the fixture component 5 to move.

[0037] Refer to Figure 2, four connecting frames 10 are respectively fixedly connected to two driving seats 9. A partition plate 7 is fixedly connected to the midline of the inner wall of the mounting seat 1. A first bidirectional screw 8 is installed through the partition plate 7. The setting of the partition plate 7 facilitates the support of the first bidirectional screw 8 and separates the two driving seats 9 at the same time.

[0038] Refer to Figures 1-2 , a rotating part 3 connected to the first bidirectional screw 8 is rotatably connected to the outer wall of one side of the mounting seat 1. Four symmetrically arranged circular openings 2 are formed in the outer wall of one side of the mounting seat 1. The setting of the rotating part 3 facilitates driving the first bidirectional screw 8 to rotate, and the setting of the circular openings 2 facilitates the fixed installation of the mounting seat 1.

[0039] The implementation principle of this application is as follows: When in use, first fix the mounting seat 1 on the inner wall of the cold box through the circular openings 2. When it is necessary to clamp the pipeline, first place the pipeline on one of the fixture assemblies 5, and then manually rotate the rotating part 3. When the rotating part 3 rotates, it directly drives the first bidirectional screw 8 to rotate. When the first bidirectional screw 8 rotates, it directly drives the two driving seats 9 to move towards or away from each other. When the two driving seats 9 move towards each other, they directly clamp the pipeline in the cold box. The two springs 17 in the fixture seat 11 facilitate pushing the two sliding sleeves 16 to move towards each other. When the sliding sleeves 16 move towards each other, they directly drive the arc-shaped seat 12 to press tightly on the pipeline through the connecting plate 19. When the elastic force of the spring 17 decays, the adjusting knob can be rotated to drive the second bidirectional screw 20 to rotate, driving the adjusting plate 21 to push the adjusting ring 18 to press the spring 17 tightly.

[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
