Description

Technical Field

[0001] This application relates to the field of steel pipe assembly, and in particular to a temporary assembly structure for steel pipe trial operation equipment. Background Technology

[0002] Steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is commonly used as a pipeline for transporting fluids such as oil, natural gas, coal gas, water, and certain solid materials.

[0003] After steel pipes are processed and formed, they need to be temporarily installed on certain equipment for trial operation to test their operating parameters. If a fixed installation method is used, such as drilling holes with bolts, although the installation strength of the steel pipe can be guaranteed, the drilling will cause structural damage to the steel pipe itself. Therefore, it can only be used as a substandard product or spare material, which is obviously insufficient. Summary of the Invention

[0004] To address the issue of damage to steel pipes caused by traditional fixed installation methods, this application provides a temporary assembly structure for steel pipe trial operation equipment.

[0005] The temporary assembly structure for a steel pipe trial operation equipment provided in this application adopts the following technical solution: A temporary assembly structure for a steel pipe trial operation equipment includes a mounting frame detachably connected to the trial operation equipment, wherein the mounting frame is circumferentially arranged with a plurality of clamping elements for abutting against the inner wall of the steel pipe.

[0006] By adopting the above technical solution, during installation, workers insert multiple clamping parts into the end of the steel pipe. The multiple clamping parts cooperate to clamp the inner wall of the steel pipe. Afterwards, the workers assemble the mounting frame onto the trial operation equipment. The assembly structure is stable and will not damage the steel pipe.

[0007] Optionally, the clamping element includes a fan-shaped abutment arranged on the mounting bracket, the arc surface of which abuts against the inner wall of the steel pipe.

[0008] By adopting the above technical solution, the contact area between the fan-shaped abutment block and the inner wall of the steel pipe is relatively large, which is beneficial to improving the firmness of the steel pipe assembly.

[0009] Optionally, the abutment is made of copper.

[0010] By adopting the above technical solution, the copper phase is softer than the steel pipe, which reduces the possibility of damage to the steel pipe caused by rigid contact between the block and the steel pipe.

[0011] Optionally, the abutting component includes a telescopic plate seat arranged on the mounting frame and pressure plates hinged to the mounting frame and located on both sides of the telescopic plate seat. The telescopic plate seat has telescopic holes, and telescopic abutting rods for abutting against the inner wall of the steel pipe are slidably fitted into the telescopic holes. The telescopic holes are filled with filler. Turnover grooves communicating with the telescopic holes are opened on both sides of the telescopic plate seat. The pressure plates are provided with protruding pressure strips extending into the turnover grooves and slidingly fitted therewith. Two coaxially arranged spur gears are rotatably mounted in the mounting frame. Multiple pressure plates with opposite positions of the abutting components correspond to the same spur gear and are provided with ring teeth that mesh with the corresponding spur gear. Transmission helical gears are also arranged on opposite sides of the two spur gears. A linkage helical gear meshing between the two transmission helical gears is rotatably arranged in the mounting frame. The mounting frame is also provided with a locking component for locking the linkage helical gear.

[0012] By employing the above technical solution, workers manually rotate two pressure plates in the same group, bringing them closer together. The pressure plates cause the convex pressure strip to rotate within the turnover groove, squeezing the filler. The filler pushes the telescopic abutment rods out of the telescopic holes and against the inner wall of the steel pipe. Spur gears, transmission helical gears, and linkage helical gears work together to link multiple sets of abutment components. Thus, when a worker manually operates one set of abutment components, the others move accordingly. Once all telescopic abutment rods are pressed against the inner wall of the steel pipe, the worker locks the linkage gears, ensuring the abutment components remain pressed against the inner wall of the steel pipe.

[0013] Optionally, the locking element includes a pivot pin that is rotatably mounted on the mounting frame. One end of the pivot pin extends into the mounting frame and a linkage helical gear is fixedly sleeved on the pivot pin. The other end extends out of the mounting frame and is provided with a locking plate. The locking plate is threadedly connected with a locking bolt for abutting against the outer wall of the mounting frame.

[0014] By adopting the above technical solution, after the telescopic rod is pressed against the inner wall of the steel pipe, the worker manually tightens the locking bolt, thereby pressing the locking bolt against the outer wall of the mounting frame, thus realizing the locking of the linkage helical gear, which is convenient to operate.

[0015] Optionally, an arc-shaped elastic abutment is arranged at the end of the telescopic abutment away from the axis of the mounting frame. A sliding groove is opened on the circumferential side wall of the telescopic plate seat, and a slider slides in the sliding groove. A top support rod is hinged between the arc end of the elastic abutment and the slider. A threaded top rod is also hinged on the slider. A rotating seat is hinged on the pressure plate, and a top support nut that abuts against the rotating seat is threaded onto the threaded top rod.

[0016] By adopting the above technical solution, after the telescopic abutment pushes the elastic abutment against the inner wall of the steel pipe, the worker then tightens the top support nut. Under the action of the threaded engagement, the threaded top rod rotates and pushes the slider away from the mounting frame. The top support rod rotates under force and pushes the elastic abutment to deform until the elastic abutment near the end also presses against the inner wall of the steel pipe. This increases the contact area between the abutment and the steel pipe and improves the stability of the steel pipe assembly.

[0017] Optionally, a limiting groove is provided radially on the telescopic abutment relative to the axis of the mounting frame, and a limiting bracket is arranged on the telescopic plate seat extending into the limiting groove and slidingly engaging with it. The limiting bracket is also provided with two limiting protrusions for limiting the maximum included angle between two pressure plates in the same group, and the two pressure plates in the same group are located between the corresponding two limiting protrusions.

[0018] By adopting the above technical solution, the limiting straight groove and the limiting bracket work together to limit the maximum extension length of the telescopic abutment. The two limiting protrusions work together to limit the maximum included angle between the two pressure plates in the same group, reducing the possibility that the pressure plate rotation angle is too large, causing the convex pressure strip to rotate out of the turnover groove and the packing to leak.

[0019] Optionally, the telescopic abutment is coated with polytetrafluoroethylene.

[0020] By adopting the above technical solution, polytetrafluoroethylene has a low coefficient of friction, which helps to improve the smoothness of the sliding of the telescopic rod within the telescopic hole.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During installation, workers insert multiple clamping parts into the end of the steel pipe. The multiple clamping parts cooperate to clamp the inner wall of the steel pipe. Afterwards, the workers assemble the mounting frame onto the trial operation equipment. The assembly structure is stable and will not damage the steel pipe. 2. The worker manually rotates two pressure plates in the same group, bringing them closer together. The pressure plates drive the convex pressure strip to rotate within the turnover groove, squeezing the packing material. The packing material pushes the telescopic abutment rods out of the telescopic holes and against the inner wall of the steel pipe. Spur gears, transmission helical gears, and linkage helical gears work together to link multiple sets of abutment components. Thus, when the worker manually operates one set of abutment components, the rest move accordingly. After all the telescopic abutment rods are against the inner wall of the steel pipe, the worker locks the linkage gears to maintain the abutment components against the inner wall of the steel pipe. 3. After the telescopic rod is pressed against the inner wall of the steel pipe, the worker manually tightens the locking bolt, so that the locking bolt is pressed against the outer wall of the mounting frame, thereby realizing the locking of the linkage helical gear, which is easy to operate; 4. After the telescopic abutment pushes the elastic abutment against the inner wall of the steel pipe, the worker then tightens the top support nut. Under the action of the threaded engagement, the threaded top rod rotates and pushes the slider away from the mounting bracket. The top support rod rotates under force and pushes the elastic abutment to deform until the elastic abutment near its end also presses against the inner wall of the steel pipe. This increases the contact area between the abutment and the steel pipe and improves the stability of the steel pipe assembly. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a temporary assembly structure for a steel pipe trial operation equipment.

[0029] Example 1 Reference Figure 1 The temporary assembly structure of the steel pipe trial operation equipment includes a mounting frame 1 bolted to the trial operation equipment. The mounting frame 1 has multiple clamping parts evenly arranged circumferentially to clamp the inner wall of the steel pipe.

[0030] Reference Figure 1 The clamping component includes a fan-shaped clamping block 2 that is bolted to the mounting bracket 1. The arc surface of the clamping block 2 is pressed against the inner wall of the steel pipe. The clamping block 2 is made of copper.

[0031] Reference Figure 1In actual use, in order to facilitate disassembly and assembly, the mounting bracket 1 can be designed as an integral unit or as a separate unit. Each separate unit corresponds to at least one abutment block 2.

[0032] The implementation principle of Example 1 is as follows: During installation, workers insert multiple abutment blocks 2 into the end of the steel pipe. The arc surfaces of the multiple abutment blocks 2 fit together to press against the inner wall of the steel pipe. Then, the workers bolt the installation to the trial operation equipment. The assembly structure is stable and will not damage the steel pipe.

[0033] Example 2 Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the clamping member includes a telescopic plate seat 30 welded to the mounting frame 1 and a pressure plate 31 hinged to the mounting frame 1 and located on both sides of the telescopic plate seat 30 in the circumferential direction.

[0034] The telescopic plate base 30 has a telescopic hole 301 radially opened relative to the axis of the mounting frame 1. The telescopic hole 301 is closed at one end near the axis of the mounting frame 1 and open at the other end. The telescopic hole 301 is slidably fitted with a telescopic abutment rod 32. The telescopic abutment rod 32 is coated with polytetrafluoroethylene. The telescopic hole 301 is filled with a filler 33, which is made of fine sand or gel-like material in the prior art.

[0035] Reference Figure 2 and Figure 3 Both sides of the telescopic plate seat 30 are provided with turnover grooves 302 that communicate with the telescopic hole 301. The pressure plate 31 has an integrally formed protruding pressure strip 34 that extends into the turnover groove 302 and slides with it.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The mounting frame 1 has a mounting cavity 101. Two coaxial spur gears 4 are rotatably mounted on the side wall of the mounting frame 1 relative to the mounting cavity 101. Multiple pressure plates 31 with opposite positions of the clamping parts correspond to the same spur gear 4. The end of the pressure plate 31 extends into the mounting cavity 101 and is integrally formed with ring teeth 5 for meshing with the spur gear 4.

[0037] Reference Figure 2 , Figure 3 and Figure 4 Two spur gears 4 are respectively welded to opposite sides of the transmission helical gears 6. The mounting bracket 1 is rotatably mounted on the side wall of the mounting cavity 101, and a linkage helical gear 7 meshing between the two transmission helical gears 6 is arranged on the mounting bracket 1. A locking element for locking the linkage helical gear 7 is also arranged on the mounting bracket 1.

[0038] Reference Figure 2 , Figure 3 and Figure 4The locking component includes a pivot pin 81 that is rotatably mounted on the mounting bracket 1. One end of the pivot pin 81 extends into the mounting bracket 1 and a linkage helical gear 7 is fixedly sleeved on the pivot pin 81. The other end extends out of the mounting bracket 1 and is integrally formed with a locking plate 82. Multiple locking bolts 83 that abut against the outer wall of the mounting bracket 1 are threaded onto the locking plate 82.

[0039] Reference Figure 2 , Figure 3 and Figure 4 During installation, the worker manually rotates the two pressure plates 31 in the same group to bring them closer together. The pressure plates 31 drive the convex pressure strip 34 to rotate in the turnover groove 302 and squeeze the filler 33. The filler 33 pushes the telescopic abutment rod 32 to slide out of the telescopic hole 301 and abut against the inner wall of the steel pipe.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The ring gear 5, spur gear 4, transmission helical gear 6 and linkage helical gear 7 link the various clamping parts together, so that when the worker operates any clamping part, the other clamping parts will also move accordingly, and the telescopic rods 32 of the multiple clamping parts press against the inner wall of the steel pipe.

[0041] At this time, the worker turns each locking bolt 83 in turn, so that each locking bolt 83 is pressed against the outer wall of the mounting bracket 1, thereby locking the pivot pin 81 and reducing the possibility of the linkage helical gear 7 reversing and causing the pressing state to loosen.

[0042] Reference Figure 3 An arc-shaped elastic abutment 9 is welded to one end of the telescopic abutment rod 32 away from the axis of the mounting frame 1. A sliding groove 303 is opened on the circumferential side wall of the telescopic plate seat 30, and a slider 10 slides in the sliding groove 303.

[0043] A top support rod 11 is hinged between the arc-shaped end of the elastic abutment 9 and the slider 10, and a threaded top rod 12 is also hinged to the slider 10. A rotating seat 13 is hinged to the pressure plate 31, and a top support nut 14 that abuts against the rotating seat 13 is threaded onto the threaded top rod 12.

[0044] Reference Figure 3 The worker tightens the top support nut 14. Under the action of the threaded engagement, the threaded top rod 12 rotates and pushes the slider 10 away from the mounting bracket 1. The top support rod 11 rotates under force and pushes the elastic abutment 9 to deform until the elastic abutment 9 is also pressed against the inner wall of the steel pipe near its end. This increases the contact area between the abutment and the steel pipe and improves the stability of the steel pipe assembly.

[0045] Reference Figure 2A limiting groove 304 is radially formed on the telescopic abutment 32 relative to the axis of the mounting bracket 1. A limiting bracket 15 is bolted to the telescopic plate seat 30, and the limiting bracket 15 extends into the limiting groove 304 and slides with it. The limiting groove 304 and the limiting bracket 15 cooperate to limit the maximum extension length of the telescopic abutment 32.

[0046] Reference Figure 2 The limiting bracket 15 also has two integrally formed limiting protrusions 16, and the two pressure plates 31 in the same group are located between the corresponding two limiting protrusions 16. The two limiting protrusions 16 cooperate to limit the maximum included angle between the two pressure plates 31 in the same group, reducing the possibility that the pressure plate 31 rotates too much, causing the convex pressure strip 34 to rotate out of the turnover groove 302 and the packing 33 to leak.

[0047] The implementation principle of Example 2 is as follows: During installation, the worker manually rotates the two pressure plates 31 in the same group to bring them closer together. The pressure plates 31 drive the convex pressure strip 34 to rotate in the turnover groove 302 and squeeze the filler 33. The filler 33 pushes the telescopic rod 32 to slide out of the telescopic hole 301.

[0048] Ring gear 5, spur gear 4, transmission helical gear 6 and linkage helical gear 7 link the various clamping parts together, so that when the worker operates any clamping part, the other clamping parts will also move accordingly, and the telescopic rods 32 of multiple clamping parts extend simultaneously.

[0049] After the elastic abutment 9 is pressed against the inner wall of the steel pipe, the worker tightens each locking bolt 83 so that each locking bolt 83 is pressed against the outer wall of the mounting bracket 1. Then the worker tightens the top support nut 14. Under the action of the threaded engagement, the threaded top rod 12 rotates and pushes the slider 10 away from the mounting bracket 1. The top support rod 11 is subjected to force and rotates, pushing the elastic abutment 9 to deform until the elastic abutment 9 is also pressed against the inner wall of the steel pipe near its end. This achieves the non-destructive assembly of the steel pipe on the trial operation equipment.

[0050] 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.
