Description

Technical Field

[0001] This utility model belongs to the field of protective device technology, specifically relating to a novel pressure pipeline protective sleeve. Background Technology

[0002] Pressure pipelines are a type of pipeline system, consisting of pipeline components, pipeline supports, safety protection devices, and auxiliary facilities. Pressure pipelines are subjected to pressure, either internally or externally, and the medium they transport is "gas, liquefied gas, and steam" or "liquids that may cause combustion, explosion, poisoning, or corrosion."

[0003] Currently, the transportation industry has begun to protect and improve pressure pipelines, and many protective devices for pressure pipelines have been put into widespread use. However, there are still many shortcomings that need to be improved. For example, the height of the protective sleeve is fixed. Due to the different installation positions of pressure pipelines, there may be a certain height difference between different positions, but the height of the protective sleeve cannot be adjusted according to the actual use needs, which affects the connection between multiple pressure pipelines and affects the installation efficiency of pressure pipelines. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of pressure pipeline protective sleeve to solve the problem mentioned in the background art where the height of the protective sleeve is fixed. Since the installation positions of pressure pipelines are different, there may be a certain height difference between different positions, but the height of the protective sleeve cannot be adjusted according to actual use needs, thereby affecting the connection between multiple pressure pipelines and affecting the installation efficiency of pressure pipelines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel pressure pipeline protective sleeve, comprising a base and a fixed box movably connected to the surface of the base, wherein a through hole is provided on one side of the outer wall of the base, and an adjusting shaft is rotatably connected to the through hole on one side of the base, and a driving bevel gear is fixed to the end face of the adjusting shaft, and a rotating column fixedly connected to the fixed box is rotatably connected to the bottom wall of the inner cavity of the base, and a driven bevel gear meshing with the driving bevel gear is fixed to the outer wall of the rotating column;

[0006] The top of the fixed box has a rotating hole, and a connecting shaft is rotatably connected to the rotating hole at the top of the fixed box. A driving gear is fixed to the outer wall of the connecting shaft. A lifting screw is rotatably connected to the bottom wall of the inner cavity of the fixed box, and a driven gear that meshes with the driving gear is fixed to the lower half of the outer wall of the lifting screw. A connecting sleeve is threaded to the outer wall of the lifting screw. A buffer box is fixed to the top of the connecting sleeve. Multiple damping buffers are installed on the bottom wall of the inner cavity of the buffer box, and a limit plate is installed on the surface of the damping buffer. A lower protective sleeve is fixed to the surface of the limit plate, and an upper protective sleeve is movably connected to the surface of the lower protective sleeve.

[0007] In a further embodiment, the bottom wall of the inner cavity of the buffer box is fixed with a plurality of fixed sleeves, and the fixed sleeves are provided with buffer springs, and the top of the buffer springs is provided with connecting pins that are fixedly connected to the limiting plate.

[0008] In a further embodiment, a turntable is fixed to the end face of the adjusting shaft located outside the base, and a support block that is rotatably connected to the adjusting shaft is fixed to the bottom wall of the inner cavity of the base.

[0009] In a further embodiment, a turntable is fixed to the end face of the connecting shaft located outside the fixed box. Two limiting holes are symmetrically opened on the top of the fixed box, and a limiting pin that is fixedly connected to the buffer box is movably connected in the limiting hole on the top of the fixed box.

[0010] In a further embodiment, a turntable is fixed to the end face of the connecting shaft located outside the fixed box. Two limiting holes are symmetrically opened on the top of the fixed box, and a limiting pin that is fixedly connected to the buffer box is movably connected in the limiting hole on the top of the fixed box.

[0011] In a further embodiment, the outer wall of the fixing bolt is threaded with a nut, and the inner walls of both the lower protective sleeve and the upper protective sleeve are fixed with protective pads.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This new type of pressure pipeline protective sleeve places the pressure pipeline between the lower protective sleeve and the upper protective sleeve. The rotating disc drives the connecting shaft and the drive gear to rotate. The drive gear drives the lifting screw to rotate through the driven gear, thereby driving the connecting sleeve and the buffer box to rise and fall. The height of the pressure pipeline can be flexibly adjusted according to the installation requirements of multiple pressure pipelines.

[0014] The turntable drives the adjusting shaft and the driving bevel gear to rotate, which in turn drives the driven bevel gear and the rotating column to rotate, thereby adjusting the angle of the fixed box. Based on the installation position of multiple pressure pipelines, the pressure pipelines are adjusted to the appropriate angle to avoid the installation of pressure pipelines being affected by multiple pressure pipelines not being on the same straight line.

[0015] By using a fixed sleeve, buffer spring, and connecting pin, along with a damping buffer, vibrations generated during the pressure pipeline transportation process can be absorbed, ensuring the stability of the pressure pipeline during operation. At the same time, the lower protective sleeve, upper protective sleeve, and protective pad can effectively protect the pressure pipeline. This new type of pressure pipeline protective sleeve can flexibly adjust its height and angle according to the installation position of the pressure pipeline, facilitating the connection between multiple pressure pipelines. It also has a good buffering function, ensuring the stability of the pressure pipeline during operation. Attached Figure Description

[0025] Please see Figure 1-5This utility model provides a novel pressure pipeline protective sleeve, including a base 1 and a fixed box 8 movably connected to the surface of the base 1. A through hole is opened on one side of the outer wall of the base 1, and an adjusting shaft 2 is rotatably connected to the through hole on one side of the base 1 through a welded bearing. A turntable 3 is welded to the end face of the adjusting shaft 2 outside the base 1, and a driving bevel gear 4 is welded to the end face of the adjusting shaft 2. A support block 5 is welded to the bottom wall of the inner cavity of the base 1 and rotatably connected to the adjusting shaft 2.

A rotating column 6 is rotatably connected to the bottom wall of the inner cavity of the base 1 through the welded bearing and fixedly connected to the fixed box 8, and a driven bevel gear 7 meshing with the driving bevel gear 4 is welded to the outer wall of the rotating column 6.

[0026] The top of the fixed box 8 has a rotating hole, and a connecting shaft 9 is rotatably connected to the rotating hole at the top of the fixed box 8 via a welded bearing. A turntable 10 is welded to the end face of the connecting shaft 9 located outside the fixed box 8. A drive gear 11 is welded to the outer wall of the connecting shaft 9. A lifting screw 12 is rotatably connected to the bottom wall of the inner cavity of the fixed box 8 via a welded bearing. A driven gear 13 that meshes with the drive gear 11 is welded to the lower half of the outer wall of the lifting screw 12. A connecting sleeve 14 is threaded to the outer wall of the lifting screw 12. A buffer box 16 is welded to the top of the connecting sleeve 14. 6 is movably connected to the fixed box 8. The top of the fixed box 8 has two symmetrical limit holes, and the limit holes on the top of the fixed box 8 are movably connected to the limit pins 15 that are welded and fixed to the buffer box 16. The limit pins 15 can restrict the movement path of the buffer box 16 when the lifting screw 12 rotates, so as to ensure that the buffer box 16 rises and falls vertically above the fixed box 8. Both the turntable 3 and the turntable 2 are provided with threaded holes, and positioning bolts are threaded into the threaded holes of the turntable 3 and the turntable 2. Tightening the positioning bolts can fix the position of the turntable 3 and the turntable 2.

[0027] Multiple damping buffers 20 are bolted to the bottom wall of the inner cavity of the buffer box 16. Limiting plates 21, movably connected to the buffer box 16, are mounted on the surface of each damping buffer 20. Multiple fixing sleeves 17 are bolted to the bottom wall of the inner cavity of the buffer box 16. Buffer springs 18 are installed inside each fixing sleeve 17, and connecting pins 19, which are fixedly connected to the limiting plates 21, are provided at the top of each buffer spring 18. A lower protective sleeve 22 is welded to the surface of the limiting plate 21. An upper protective sleeve 23 is movably connected to the surface of the lower protective sleeve 22. Protective pads 24 are fixed to the inner walls of both the lower and upper protective sleeves 22. Fixing blocks 25 are welded to both outer walls of the protective sleeve 23. Fixing holes are provided on the fixing blocks 25, and fixing bolts 26 are inserted into the fixing holes of the fixing blocks 25. Nuts are threaded onto the outer wall of the fixing bolts 26. The pressure pipe is placed between the lower protective sleeve 22 and the upper protective sleeve 23. The turntable 3 drives the adjusting shaft 2 and the driving bevel gear 4 to rotate, thereby driving the driven bevel gear 7 and the rotating column 6 to rotate, thereby adjusting the angle of the fixing box 8. According to the installation position of multiple pressure pipes, the pressure pipes are adjusted to a suitable angle to avoid the installation of pressure pipes being affected by multiple pressure pipes not being on the same straight line.

[0028] The turntable 10 drives the connecting shaft 9 and the drive gear 11 to rotate. The drive gear 11 drives the lifting screw 12 to rotate through the driven gear 13, thereby driving the connecting sleeve 14 and the buffer box 16 to rise and fall. According to the installation requirements of multiple pressure pipelines, the height of the pressure pipeline can be flexibly adjusted. With the setting of the fixed sleeve 17, buffer spring 18 and connecting pin 19, and in conjunction with the damping buffer 20, vibration can be absorbed when vibration occurs during the pressure pipeline transportation process, ensuring the stability of the pressure pipeline during operation. At the same time, the lower protective sleeve 22, the upper protective sleeve 23 and the protective pad 24 can effectively protect the pressure pipeline.

[0030] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Working principle:

[0032] When using this new type of pressure pipeline protective sleeve, unscrew the fixing bolt 26, remove the upper protective sleeve 23 from the surface of the lower protective sleeve 22, place the pressure pipeline inside the lower protective sleeve 22, place the upper protective sleeve 23 on the surface of the lower protective sleeve 22, insert the fixing bolt 26 into the fixing block 25, and then tighten the nut onto the fixing bolt 26 to fix the position of the pressure pipeline. The pressure pipeline is effectively protected by the lower protective sleeve 22, the upper protective sleeve 23, and the protective pad 24.

[0033] When multiple pressure pipelines are connected, the turntable 3 drives the adjusting shaft 2 and the driving bevel gear 4 to rotate, which in turn drives the driven bevel gear 7 and the rotating column 6 to rotate, thereby adjusting the angle of the fixed box 8. According to the installation position of multiple pressure pipelines, the pressure pipelines are adjusted to a suitable angle to avoid the installation of pressure pipelines being affected by multiple pressure pipelines not being on the same straight line.

[0034] The turntable 10 drives the connecting shaft 9 and the drive gear 11 to rotate. The drive gear 11 drives the lifting screw 12 to rotate through the driven gear 13, thereby driving the connecting sleeve 14 and the buffer box 16 to rise and fall. According to the installation requirements of multiple pressure pipelines, the height of the pressure pipeline can be flexibly adjusted. By setting the fixed sleeve 17, buffer spring 18 and connecting pin 19, and cooperating with the damping buffer 20, vibration is absorbed when vibration occurs during the pressure pipeline transportation process, ensuring the stability of the pressure pipeline during operation.
