Description

Technical Field

[0001] This utility model belongs to the field of tower equipment technology, specifically a protective device for the pipe leading out from the lower end cap during tower transportation. Background Technology

[0002] In recent years, with the development of the chemical industry, the quality requirements for tower equipment have gradually increased, making the manufacturing and transportation processes of tower equipment crucial for producing high-quality products. One end of the outlet pipe on the lower end cap of the tower is welded to the lower end cap, while the other end is led to the outside of the skirt support through a channel pipe. Considering the thermal expansion generated during actual operation, the design reserves sufficient clearance between the outer circumference of the outlet pipe and the channel pipe (refer to section 5.2.7 of HG / T 20652-1998 "Technical Specifications for Tower Design"), resulting in the outlet pipe being suspended inside the tower equipment. Furthermore, considering that tower equipment will experience bumps, vibrations, swaying, and impacts during transportation, leading to deformation, paint peeling, weld cracking, and even malfunctions, the tower equipment may fail to operate normally. Utility Model Content

[0003] To avoid damage to tower equipment during transportation, the purpose of this utility model is to provide a protective device for the outlet pipe on the lower end cap during tower transportation.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model includes telescopic outriggers, a support plate, an adjusting pad, wing plates, and two protective covers. Each protective cover is semi-circular, with wing plates on both sides. The two protective covers sandwich the outlet pipe between them. The support plate is located below the two protective covers. The distance between the wing plates of the two protective covers and between the support plate and the wing plate of the lower protective cover is adjustable and remains relatively fixed after adjustment. Each protective cover is connected to an adjusting pad, one end of which abuts against the outlet pipe, and the other end of which is movable relative to the protective cover and remains relatively fixed after being moved into position. Two sets of telescopic outriggers are connected to the support plate. Each set of telescopic outriggers includes a base, a threaded rod, and two internally threaded reinforcing tubes. The two ends of the threaded rod are threaded to one end of each of the two internally threaded reinforcing tubes. The other end of one internally threaded reinforcing tube is fixed to the support plate, and the other end of the other internally threaded reinforcing tube is connected to a base for contacting the inner wall of the skirt during transportation.

[0006] Wherein: the wing plates of the two protective covers and the support plate are connected by multiple sets of long studs and hexagonal head nuts B. One end of each set of long studs passes through the support plate and is fixed on the upper and lower sides of the support plate by two hexagonal head nuts B connected by threads; the other end of each set of long studs passes through the wing plates of the two protective covers and is clamped by the two hexagonal head nuts B connected by threads, thereby securing the lead-out pipe.

[0007] Each of the protective covers is connected to a set of two adjusting pads, which are connected to the protective cover via hexagonal head nuts C and double-ended studs. One end of the double-ended stud is connected to the two adjusting pads, and the other end of the double-ended stud protrudes from the protective cover. Two hexagonal head nuts C are threaded onto the double-ended stud, which is located on the inner and outer sides of the protective cover, respectively. The double-ended stud drives the adjusting pads to move relative to the protective cover, thereby accommodating lead-out pipes of different diameters. After adjustment, the protective cover is clamped with the two hexagonal head nuts C.

[0008] The adjusting pad is fan-shaped, and a notch is provided on the side of the adjusting pad away from the outlet pipe to facilitate tightening the hexagonal head nut C.

[0009] An arc-shaped asbestos-free rubber sheet is provided between the adjusting pad and the outlet pipe.

[0010] A large hexagonal head nut is fixed to the threaded round rod to facilitate tightening the threaded round rod.

[0011] The base includes a base plate and a connecting plate. One end of the connecting plate is connected to the other end of another internally threaded reinforcing tube via a hexagonal head stud and a hexagonal head nut A. The other end of the connecting plate is fixedly connected to the base plate.

[0012] The base plate is an arc-shaped plate. When the skirt seat is cylindrical, the base plate is separated from the inner wall of the skirt seat by an asbestos-free rubber sheet. When the skirt seat is conical, the base plate is welded to the inner wall of the skirt seat.

[0013] The advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model has a simple structure. It fixes the pipe leading out from the lower end cap of the tower, absorbs the energy generated by bumps and vibrations during equipment transportation, and avoids scratches on the base material and cracks in the weld.

[0015] 2. This utility model adopts a multi-bolt connection structure, which avoids on-site hot work on the tower equipment and allows the protective device to be completely removed from the tower equipment without using flame cutting.

[0016] 3. The protective cover of this utility model has a built-in asbestos-free rubber sheet. The asbestos-free rubber sheet has good buffering and pressure resistance, which isolates the protective device from the lead-out pipe on the lower end cap of the tower, preventing the paint on the lead-out pipe from peeling off and avoiding equipment corrosion that would affect its service life.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] like Figures 1-4As shown, this utility model includes telescopic outriggers, a support plate 10, an adjusting pad 11, wing plates 12, and two protective covers 13. Each protective cover 13 is semi-circular, with wing plates 12 welded to both sides. The two protective covers 13 are interlocked, clamping the outlet pipe 18 in the middle. The support plate 10 is located below the two protective covers 13. The distance between the wing plates 12 of the two protective covers 13 and between the support plate 10 and the wing plate 12 of the lower protective cover 13 are adjustable and remain relatively fixed after adjustment. For outlet pipes 18 of different diameters on the lower end cap 19 of the tower, each protective cover 13 is connected to... An adjusting pad 11 is attached, one end of which abuts against the lead-out pipe 18, and the other end of which can be relatively moved to connect with the protective cover 13 and remain relatively fixed to the protective cover 13 after being moved into place. Two sets of telescopic legs are connected to the support plate 10. Each set of telescopic legs includes a base, a threaded round rod 7 and two internally threaded reinforcing tubes 5. The two ends of the threaded round rod 7 are respectively threaded to one end of the two internally threaded reinforcing tubes 5. The other end of one internally threaded reinforcing tube 5 is fixed to the support plate 10, and the other end of the other internally threaded reinforcing tube 5 is connected to a base for contacting the inner wall of the skirt 17 during transportation.

[0026] In this embodiment, the wing plates 12 of the two protective covers 13 and the support plate 10 are connected by multiple sets of long studs 9 and hexagonal head nuts B8. One end of each set of long studs 9 passes through the support plate 10 and is fixed on the upper and lower surfaces of the support plate 10 by two hexagonal head nuts B8 connected by threads. The other end of each set of long studs 9 passes through the wing plates 12 of the two protective covers 13 and is clamped by two hexagonal head nuts B8 connected by threads, thereby securing the lead-out pipe 18.

[0027] In this embodiment, each protective cover 13 is connected to a set of two adjusting pads 11, which are connected to the protective cover 13 via hexagonal head nuts C14 and double-ended studs 15. One end of the double-ended stud 15 is welded to the two adjusting pads 11, and the other end of the double-ended stud 15 protrudes from the protective cover 13. Two hexagonal head nuts C14 are threaded onto the double-ended stud 15, and the two hexagonal head nuts C14 are located on the inner and outer sides of the protective cover 13, respectively. By adjusting the double-ended stud 15, the double-ended stud 15 drives the adjusting pads 11 to move relative to the protective cover 13, thereby adapting to lead-out pipes 18 of different diameters. After adjustment, the protective cover 13 is clamped with the two hexagonal head nuts C14. In this embodiment, the adjusting pads 11 are fan-shaped, and a notch 20 is provided on the side of the adjusting pad 11 away from the lead-out pipe 18 to facilitate tightening the hexagonal head nuts C14.

[0028] In this embodiment, an arc-shaped asbestos-free rubber plate 16 is provided between the adjusting pad 11 and the outlet pipe 18. The asbestos-free rubber plate 16 has good buffering and pressure resistance, which isolates the protective device from the outlet pipe 18, prevents the paint on the surface of the outlet pipe 18 from peeling off, and avoids equipment corrosion that affects its service life.

[0029] In this embodiment, a large hexagonal head nut 6 is welded onto the threaded round rod 7. The large hexagonal head nut 6 acts as a wrench, making it easy to tighten the threaded round rod 7. The lead-out pipe 18 on the lower end cap 19 of the tower should be subjected to uniform force during transportation. In this embodiment, the other end of the internally threaded reinforcing pipe 5 of one of the two sets of telescopic legs is fixed and the opening angle is adjusted before being welded to the support plate 10.

[0030] The base in this embodiment includes a base plate 1 and a connecting upright plate 2. One end of the connecting upright plate 2 is connected to the other end of another internally threaded reinforcing tube 5 via a hexagonal head stud 4 and a hexagonal head nut A3. The other end of the internally threaded reinforcing tube 5 has a through hole through which the hexagonal head stud 4 passes, and is then threadedly connected to the hexagonal head nut A3 for fixation. The other end of the connecting upright plate 2 is fixedly connected to the base plate 1. In this embodiment, the base plate 1 is an arc-shaped plate. When the skirt 17 is cylindrical, the internal structure of the cylindrical skirt 17 is relatively stable, and the base plate 1 and the inner wall of the skirt 17 are in stable contact. The base plate 1 and the inner wall of the skirt 17 are separated by a non-asbestos rubber sheet. Figure 5 As shown; when the skirt 17 is conical, the internal structure of the conical skirt 17 is relatively steep and has no supporting fixing surface. Therefore, the base plate 1 needs to be welded to the inner wall of the skirt 17 for fixation before the tower equipment is transported to the user's site. Figure 6 As shown.

[0031] Based on the structural characteristics of the lead-out pipe 18 on the lower end cap 19 of the tower equipment, this utility model installs a protective device before packaging the tower equipment, which plays an important role in ensuring the quality of the tower equipment.
