Description

Technical Field

[0001] This utility model belongs to the field of large equipment transportation, specifically relating to a large vertical cylindrical section transportation reinforcement system. Background Technology

[0002] With the increasing scale of chemical equipment, many reactors in the chemical and oil refining fields weigh over 1,000 tons, with the heaviest exceeding 3,000 tons. These large reactors are often manufactured in factories as multi-section cylindrical units, which are then transported to the delivery site for assembly by welding. These sections range in weight from tens to hundreds of tons and have large diameters, typically 4 to 7 meters. During transport, they are often transported vertically (with the section's axis perpendicular to the ground) to avoid exceeding height limits after loading and to prevent the dangers of the cylindrical sections rolling during transport. However, due to the large weight of the sections, hydraulic trailers are typically used for loading, but reinforcing the sections remains a challenge. Firstly, there are no reinforcement points on the sections, making it difficult to use common rigging. Secondly, the end faces of the sections are machined with weld bevels, which are easily damaged by chains and wire ropes, while flexible rigging such as synthetic fibers is easily cut by the sharp edges of the bevels.

[0003] Currently, the common solution to the problem of securing vertically mounted cylindrical sections during transport is to directly weld steel blocks onto the platform of the transport vehicle. Specifically, workers weld multiple blocks to corresponding positions on the platform based on the diameter of the cylindrical section and its position during transport. These blocks form a circumferential barrier at the bottom of the cylindrical section, preventing horizontal movement. While this method solves the problem of horizontal movement of the cylindrical section during transport without the need for rigging, it also has the following drawbacks:

[0004] Firstly, each cylindrical section needs to be reinforced by welding on-site before transportation, and the reinforcement blocks need to be cut off after transportation. The entire reinforcement and removal process is time-consuming, resulting in low work efficiency.

[0005] Secondly, repeated welding and cutting operations on vehicle panels will severely damage the anti-corrosion layer and base material of the vehicle panels, shorten the service life of the vehicle, and increase maintenance costs.

[0006] Third, each reinforcement requires the consumption of materials such as welding rods and gas, as well as electricity. Furthermore, the block itself needs to be replaced after multiple uses due to cutting wear, which increases the cost of consumables and labor, resulting in poor economic efficiency.

[0007] Fourth, the welding position is fixed. For cylinder sections of different diameters, the welding position needs to be recalculated and selected, which lacks flexibility. Utility Model Content

[0008] The purpose of this invention is to address the problems of low work efficiency, easy damage to vehicles, and poor economy of the existing technology of reinforcement by welding blocks. It provides a large vertical cylindrical transport reinforcement system. This tooling can achieve fast and reliable reinforcement and removal without welding to the vehicle, effectively protecting the vehicle's surface, improving work efficiency, and reducing operating costs.

[0009] The technical solution adopted by this utility model is: a large vertical cylindrical section transportation and reinforcement system, including two sets of radial limiting fixtures used in combination with the vehicle load-bearing frame; the vehicle load-bearing frame includes crossbeams and longitudinal beams, and the crossbeams and longitudinal beams are arranged in a crisscross pattern to form multiple gaps; the side closer to the front of the vehicle along the longitudinal direction is the front side, and the side closer to the rear of the vehicle is the rear side.

[0010] Each set of radial limiting fixtures includes at least a first radial limiting fixture and a second radial limiting fixture used side by side; the first radial limiting fixture and the second radial limiting fixture each include: a connecting base plate, a first stop structure disposed on the bottom surface of the connecting base plate for fitting into the gap of the vehicle load-bearing frame, and a baffle disposed on the top surface of the connecting base plate for limiting the radial displacement of the cylindrical section; when any set of the first radial limiting fixture and the second radial limiting fixture are installed side by side in the transverse direction on the vehicle load-bearing frame, the baffles of both are arranged on the same circumference and symmetrically arranged about the longitudinal centerline of the load-bearing surface of the vehicle load-bearing frame.

[0011] Furthermore, a sleeve is fixed to the back of the baffle, and a circular support column perpendicular to it is provided on the connecting base plate. The bottom end of the circular support column is fixed to the top surface of the connecting base plate, and the sleeve is fitted onto the circular support column and moves around the circular support column axially.

[0012] Furthermore, a reinforcing plate is provided on the back of the baffle, and the reinforcing plate is fixed perpendicularly to the baffle between the baffle and the connecting base plate.

[0013] Furthermore, a threaded rod is threadedly connected to the baffle, and a small baffle is provided at one end of the threaded rod adjacent to the baffle limiting surface. The back of the small baffle is hinged to the threaded rod, and during operation, its front side is in contact with the side wall of the cylinder section.

[0014] Furthermore, the baffle on the connecting base plate includes an outer baffle. After the cylindrical section is supported on the connecting base plate, the limiting surface of the outer baffle is in contact with or clearance fits the outer wall of the cylindrical section.

[0015] Furthermore, the baffle on the connecting base plate also includes an inner baffle. After the cylindrical section is supported on the connecting base plate, the limiting surface of the inner baffle is in contact with or clearance fits the inner wall of the cylindrical section.

[0016] Furthermore, each set of radial limiting fixtures also includes a third radial limiting fixture, which includes: a support plate with the same thickness as the connecting base plate, and a second stop structure disposed on the bottom surface of the support plate for fitting into the gap of the vehicle load-bearing frame.

[0017] Furthermore, the first stop structure includes a set of outer stop blocks located on the outer side and a set of inner stop blocks located on the inner side; the lateral spacing between the outer stop blocks and the inner stop blocks is adapted to the width of the longitudinal beam of the vehicle load-bearing frame; the longitudinal spacing between the outer stop blocks and the inner stop blocks is adapted to the width of the cross beam of the vehicle load-bearing frame.

[0018] Furthermore, it also includes multiple sets of axial limiting fixtures arranged circumferentially around the cylindrical section. Each set of axial limiting fixtures includes a hook, an adjusting screw, and a connecting plate. One end of the adjusting screw is hinged to the hook, and the other end is hinged to the connecting plate. The hook is inserted into the top of the cylindrical section, and the connecting plate is bolted to the side bolt holes of the vehicle's load-bearing frame.

[0019] Furthermore, a rubber buffer layer is provided between the hook and the cylindrical section.

[0020] The beneficial effects of this utility model are:

[0021] 1. By using a detachable radial limiting fixture to fit into the gap structure of the vehicle's load-bearing frame, the traditional welding reinforcement method is completely eliminated. The fixture is easy to install and disassemble, achieving "install and use immediately, unload and go immediately," reducing single-operation time by more than 70% and greatly improving transportation efficiency. It avoids repeated welding and cutting operations on the vehicle's surface, effectively protecting the anti-corrosion layer and base material of the vehicle's load-bearing frame, eliminating damage to the vehicle caused by reinforcement operations, significantly extending vehicle lifespan, and reducing maintenance costs. It achieves efficient and repeatable welding-free reinforcement, fundamentally solving the problems of low operation efficiency and vehicle damage.

[0022] 2. This system eliminates the need for consumables such as welding rods and gas, as well as electricity, with each transport operation. It also avoids frequent replacement of stops due to cutting wear. Over long-term use, this system saves significant material and energy costs. The tooling itself is reusable, allowing a single investment to serve multiple transport tasks of varying specifications, thus reducing the cost per use and achieving cost reduction and efficiency improvement. It significantly lowers overall operating costs, demonstrating outstanding economic advantages.

[0023] 3. By adjusting the lateral installation position of the first and second radial limiting fixtures within the gaps in the vehicle's load-bearing frame, the diameter of the limiting area enclosed by the baffles can be easily changed, thus adapting to cylinder sections of different diameters. This modular and adjustable design solves the shortcomings of traditional welded baffles, which have fixed positions and insufficient flexibility. Practical verification has shown that this system is stably applicable to various large vertical cylinder sections with diameters of 3-7 meters and weights of 100-200 tons, requiring no vehicle modifications, demonstrating strong versatility and high value for widespread application.

[0024] 4. Utilizing symmetrically arranged radial limiting fixtures, the cylinder section is automatically guided to center during lowering, achieving precise alignment between the cylinder section's axis and the vehicle's longitudinal centerline (positioning deviation ≤ 5mm). This effectively avoids transportation risks caused by center of gravity shift, ensuring accurate positioning. The dual displacement restriction formed by the radial limiting fixture (limiting horizontal movement) and the axial limiting fixture (limiting overturning and jumping), further secured by wedge-shaped wooden blocks inserted in the gaps, ensures that the radial displacement of the cylinder section during transportation is ≤ 2mm and the axial displacement is ≤ 1mm, significantly improving safety and reliability. The hinged design and buffer layer of the axial limiting fixture effectively absorb transportation vibrations, preventing damage to the cylinder section's bevel from rigid impacts.

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0039] In this specification, unless otherwise stated, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the appendix. Figure 6 The orientation or positional relationship shown is for the purpose of describing the present invention only, 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 the present invention.

[0040] The large vertical cylindrical section transportation and reinforcement system disclosed in this utility model, such as Figure 1 As shown, it includes two sets of radial limiting fixtures 3 used in conjunction with the vehicle load-bearing frame 1. The transport vehicle used is usually a hydraulic axle vehicle, and the vehicle load-bearing surface is the top surface of the vehicle load-bearing frame 1 supporting the cylindrical section 2. Unlike other flat plate-like structures, the vehicle load-bearing frame 1 is a hollow frame structure. The vehicle load-bearing frame 1 includes crossbeams 11 and longitudinal beams 12, which are arranged in a staggered pattern to form multiple gaps 13. Side bolt holes 14 are provided on both sides of the vehicle load-bearing frame 1 along the transverse direction. For ease of subsequent description, the side closer to the front of the vehicle along the longitudinal direction is referred to as the front side, and the side closer to the rear of the vehicle is referred to as the rear side. The intersection of the crossbeams 11 and the longitudinal beams 12 is called the intersection.

[0041] Each set of radial limiting fixtures 3 includes at least a first radial limiting fixture 31 and a second radial limiting fixture 32 used side by side; such as Figure 7 and Figure 8 As shown, the first radial limiting fixture 31 and the second radial limiting fixture 32 each include: a connecting base plate 311, a first stop structure 312 disposed on the bottom surface of the connecting base plate 311 for fitting into the gap 13 of the vehicle bearing frame 1, and a baffle 313 disposed on the top surface of the connecting base plate 311 for limiting the radial displacement of the cylindrical section 2; when any one of the first radial limiting fixtures 31 and the second radial limiting fixture 32 is installed side by side in the transverse direction on the vehicle bearing frame 1, the baffles 313 of the two are arranged on the same circumference and symmetrically arranged about the longitudinal centerline of the bearing surface of the vehicle bearing frame 1.

[0042] The first stop structure 312 is fitted into the gap 13 of the vehicle support frame 1. This means that the first stop structure 312 is inserted into the gap 13 of the vehicle support frame 1, and after being inserted into the gap 13, the first stop structure 312 contacts the side wall of the gap 13. Through the cooperation between the gap 13 and the first stop structure 312, the connecting base plate 311 becomes a kind of pad to support the cylinder section 2.

[0043] The baffle 313 on the connecting base plate 311 serves to radially limit the movement of the cylinder section 2. Specifically:

[0044] When the baffle 313 is the outer baffle 3131, after the cylindrical section 2 is supported by the connecting base plate 311, the limiting surface of the outer baffle 3131 is in contact with or has a clearance fit with the outer wall of the cylindrical section 2. Wedge-shaped wooden blocks or the like are inserted into the gap between the limiting surface of the outer baffle 3131 and the outer wall of the cylindrical section 2 to clamp the cylindrical section 2 and the radial limiting fixture 3, so that there will be no relative movement between the cylindrical section 2 and the radial limiting fixture 3.

[0045] When the baffle 313 is the inner baffle 3132, after the cylindrical section 2 is supported by the connecting base plate 311, the limiting surface of the inner baffle 3132 is in contact with or has a clearance fit with the inner wall of the cylindrical section 2. Wedge-shaped wooden blocks or the like are inserted into the gap between the limiting surface of the inner baffle 3132 and the inner wall of the cylindrical section 2 to clamp the cylindrical section 2 and the radial limiting fixture 3, so that there will be no relative movement between the cylindrical section 2 and the radial limiting fixture 3.

[0046] Both of the above radial limiting methods are acceptable, but the use of the inner baffle 3132 requires the operator to enter the inside of the cylinder section 2 for operation, which is inconvenient. Therefore, the outer baffle 3131 is preferred for radial limiting.

[0047] Because the relative position between the cylinder section 2 and the radial limiting fixture 3 is fixed, and the radial limiting fixture 3 is fitted into the gap 13 of the vehicle load-bearing frame 1, its relative position is fixed after installation on the vehicle load-bearing frame 1, thus determining the relative position between the cylinder section 2 and the vehicle load-bearing frame 1. Compared with traditional methods, this avoids repeated welding and cutting operations on the vehicle panel, achieving rapid and reliable reinforcement and removal without welding to the vehicle, effectively protecting the vehicle panel, improving work efficiency, and reducing operating costs.

[0048] The baffle 313 can be installed in various ways, such as Figure 7 The first embodiment of the radial limiting fixture 31 shown and Figure 8 The first embodiment of the second radial limiting fixture 32 shown illustrates the movable installation configuration of the baffle 313: a sleeve 314 is fixed to the back of the baffle 313, and a circular support column 315 perpendicular to the connecting base plate 311 is provided on the connecting base plate 311. The bottom end of the circular support column 315 is fixed to the top surface of the connecting base plate 311, and the sleeve 314 is fitted onto the circular support column 315 and movably engages with the circular support column 315 around its axial direction. Thus, the tilt angle of the baffle 313 relative to the longitudinal centerline of the vehicle's load-bearing frame 1 can be adjusted by rotating the sleeve 314 around the circular support column 315, thereby accommodating various diameter cylinder sections 2.

[0049] Figure 10 The second embodiment of the first radial limiting fixture 31 shown illustrates a fixed installation of the baffle 313. Of course, the second radial limiting fixture 32 can also adopt the same structure. This installation method involves a reinforcing plate 316 on the back of the baffle 313. The reinforcing plate 316 is fixed perpendicularly to the baffle 313 between the baffle 313 and the connecting base plate 311. This fixes the relative position of the baffle 313 on the connecting base plate 311, and the reinforcing plate 316 improves the strength of the baffle 313.

[0050] After the cylindrical section 2 is installed in place, the side wall of the cylindrical section 2 and the baffle 313 may fit perfectly. Of course, there may also be a gap between the side wall of the cylindrical section 2 and the baffle 313. In this case, wedge-shaped wooden blocks or rubber pads need to be filled between the cylindrical section 2 and the baffle 313 to eliminate the gap.

[0051] Of course, there are other structural forms that can replace the padding. For example... Figure 11The diagram shows the baffle structure of the first radial limiting fixture and the third embodiment of the second radial limiting fixture. A threaded rod 318 is threadedly connected to the outer baffle 3131. A small baffle 317 is provided at one end of the threaded rod 318 adjacent to the limiting surface of the outer baffle 3131. The back of the small baffle 317 is hinged to the threaded rod 318, and its front side fits against the outer wall of the cylindrical section 2, improving its adaptability to the arc surface of the cylindrical section 2. Furthermore, by adjusting the threaded rod 318, the small baffle 317 can be driven to contact the side wall of the cylindrical section 2, achieving the purpose of actively eliminating the gap between the cylindrical section 2 and the radial limiting fixture. Figure 11 The baffle structure shown can be applied to Figure 7 and Figure 8 In the first embodiment shown, the baffle 313 is installed in a movable form using a sleeve 314 and a circular support 315, while a small baffle 317 is installed on the baffle 313 via a threaded rod 318. Figure 11 The baffle structure shown can also be applied to Figure 10 In the second embodiment shown, the baffle 313 is fixedly installed using a reinforcing plate 316, and a small baffle 317 is installed on the baffle 313 via a threaded rod 318.

[0052] Among them, the back of the baffle 313 is relative to the front, and its front is also the limiting surface, which is the side facing the limiting area (also the cylinder placement area).

[0053] To increase the contact area with the bottom of the cylindrical section 2 and reduce the overhang area at the bottom of the cylindrical section 2, each set of radial limiting fixtures 3 also includes a third radial limiting fixture 33. In use, the third radial limiting fixture 33 is located between the first radial limiting fixture 31 and the second radial limiting fixture 32 in the same set. Figure 9 As shown, the third radial limiting fixture 33 includes: a support plate 330 with the same thickness as the connecting base plate 311, and a second stop structure 331 disposed on the bottom surface of the support plate 330 for fitting into the gap 13 of the vehicle support frame 1. Of course, to enhance the radial limiting effect on the cylinder 2, such as... Figure 12 As shown, multiple threaded holes 333 can be machined on the front side of the support plate 330 of the third radial limiting fixture 33, and the limiting block 332 can be installed on the front side of the support plate 330 by bolts to play a radial limiting role on the cylinder section 2.

[0054] The first stop structure 312 can be an insert or similar component adapted to the gap 13. In this embodiment, the first stop structure 312 includes a set of outer stop blocks 3121 located on the outer side and a set of inner stop blocks 3122 located on the inner side; the lateral distance between the outer stop blocks 3121 and the inner stop blocks 3122 is adapted to the width of the longitudinal beam 12 of the vehicle load-bearing frame 1; the longitudinal distance between the outer stop blocks 3121 and the inner stop blocks 3122 is adapted to the width of the cross beam 11 of the vehicle load-bearing frame 1. In use, it can be fitted into the gap 13 by straddling the longitudinal beam 12 or the cross beam 11, which is more conducive to limiting the relative position between the radial limiting fixture 3 and the vehicle load-bearing frame 1.

[0055] This utility model employs an independent first radial limiting fixture 31 and a second radial limiting fixture 32 for coordinated use. Each radial limiting fixture occupies a small area, making it easy to store and lighter, thus facilitating handling by operators. To further facilitate handling, lifting rings 34 are provided on the outer periphery of the connecting base plate 311 and the outer periphery of the support plate 330.

[0056] To limit the movement of the cylinder section 2 along the axial direction, this system also includes an axial limiting fixture 4, such as... Figure 6 As shown, the axial limiting fixture 4 includes a hook 41, an adjusting screw 42 and a connecting plate 43. One end of the adjusting screw 42 is hinged to the hook 41 and the other end is hinged to the connecting plate 43. The hook 41 is inserted into the top of the cylindrical section 2, and the connecting plate 43 is bolted to the side bolt hole 14 of the vehicle load-bearing frame 1.

[0057] The entire process of loading, positioning, and securing the cylindrical sections using the aforementioned large vertical cylindrical section transportation and reinforcement system is as follows:

[0058] First, we collected the structural parameters of the hydraulic axle vehicle and designed the reinforcement tooling:

[0059] 1) Parameter acquisition of hydraulic axle vehicle: The collected parameters include: the number of gaps 13 in the vehicle bearing frame 1, the length L1, width W1, and depth H1 of each gap 13; the height H2 and width W2 of the edge structure step of the bearing surface; the number, hole spacing p, and hole diameter d of the bolt holes 14 on the side of the vehicle; and the total length L and total width W of the bearing surface of the hydraulic axle vehicle.

[0060] 2) Reinforcement tooling design: Based on the collected structural parameters and the outer diameter D, height H and weight G of the large vertical cylindrical section to be transported, design the above two sets of radial limiting tooling 3 and four sets of axial limiting tooling 4 used in combination with the vehicle bearing frame 1.

[0061] Next, the reinforcement fixtures are processed and installed. This includes the following steps:

[0062] Step 1: Install radial limit fixture 3. Figures 1-3 A schematic diagram showing the installation of cylindrical sections 2 of different diameters onto the vehicle's load-bearing frame 1 via radial limiting fixture 3 is provided.

[0063] First, the first radial limiting fixture 31 and the second radial limiting fixture 32 of one set of radial limiting fixtures 3 are respectively fitted into the left and right gaps 13 on the front side of the vehicle load-bearing frame 1 through the first stop structure 312 at their bottom. Specifically, as follows... Figure 1 and Figure 4 As shown: The first radial limiting fixture 31, located on the front side, is installed at the leftmost intersection of the crossbeam 11 and the longitudinal beam 12; the second radial limiting fixture 32, also located on the front side, is installed at the rightmost intersection of the crossbeam 11 and the longitudinal beam 12; and the third radial limiting fixture 33, located on the front side, is installed between the first and second radial limiting fixtures 31 and 32. This arrangement, firstly, prevents movement of the radial limiting fixtures 3 on the bearing surface by limiting them at the intersection, thus ensuring the position of each radial limiting fixture 3 on the front side is determined. Secondly, with the position of the front radial limiting fixtures 3 determined, and given the diameter of the cylinder section 2, the installation position of the rear radial limiting fixtures 3 can be quickly determined, improving installation efficiency. Thirdly, the first radial limiting fixture 31 of the front radial limiting fixture 3 is installed at the leftmost intersection, and the second radial limiting fixture 32 is installed at the rightmost intersection. The installation span of the two fixtures is large enough along the transverse direction of the vehicle body to facilitate the bearing of the cylinder section 2. Furthermore, the positions of the left and right intersections on the front side are symmetrical with respect to the longitudinal centerline. This ensures that the installation positions of the two radial limiting fixtures are symmetrical with respect to the longitudinal centerline, which is beneficial for the cylinder section 2 to be centered on the bearing surface after positioning.

[0064] Next, the first radial limiting fixture 31 and the second radial limiting fixture 32 of another set of radial limiting fixtures 3 are respectively fitted into the left and right gaps 13 on the rear side of the vehicle carrier frame 1 via the first stop structure 312 at their bottom. This set of radial limiting fixtures 3 is positioned on the rear side of the vehicle carrier frame 1 relative to the previous set. The first radial limiting fixture 31 and the second radial limiting fixture 32 are arranged side-by-side, with the first radial limiting fixture 31 on the right and the second radial limiting fixture 32 on the left. It can be... Figure 3 As shown, it can be installed at the intersection, or as... Figure 2 and Figure 5 The longitudinal beam 12 straddles only the vehicle's load-bearing frame 1, and its specific diameter is determined according to the diameter of the cylindrical section 2. The third radial limiting fixture 33, located on the rear side, is installed between the first radial limiting fixture 31 and the second radial limiting fixture 32.

[0065] Finally, adjust the positions of all radial limiting fixtures 3 so that the longitudinal centerline of the limiting area enclosed by the baffles 313 of each radial limiting fixture 3 coincides with the longitudinal centerline of the bearing surface of the vehicle bearing frame 1. Thus, when the outer wall of the cylindrical section 2 simultaneously contacts the limiting surface of the baffles 313 of one set of radial limiting fixtures 3, the center of the cylindrical section 2 automatically coincides with the longitudinal centerline of the vehicle bearing frame 1, achieving precise centering positioning that is simple and convenient.

[0066] Step 2, Loading the cylinder sections:

[0067] First, hoist section 2 onto the vehicle's load-bearing frame 1 and slowly lower it into the limiting area until the bottom surface of section 2 is below the top of baffle 313. During the hoisting process, a large crane (with a lifting capacity ≥ 1.2 times the weight of the section) is used to vertically lift the section to be transported. The section's posture is controlled by guy ropes during hoisting to ensure the section's axis remains vertical (verticality deviation ≤ 0.5°). During this process, it is necessary to initially align the section's axis with the longitudinal centerline of the load-bearing surface (alignment deviation ≤ 50mm).

[0068] Next, the position of the cylinder section 2 is finely adjusted so that its outer circle is in uniform contact with the limiting surfaces of the two baffles 313 of the front radial limiting fixture 3 (contact gap ≤ 5mm); at this time, the cylinder section axis coincides with the longitudinal center line of the bearing surface, achieving precise centering positioning.

[0069] Then, continue lowering the cylinder section 2 until its bottom is stably placed on the connecting base plate of the radial limiting fixture 3, thus completing the loading and positioning.

[0070] Step 3: Reinforcement of the cylinder section.

[0071] The reinforcement of the cylindrical section includes radial reinforcement and axial reinforcement. Radial reinforcement involves filling the gap between the cylindrical section 2 and the baffle 313 with wedge-shaped wooden blocks or rubber pads. Alternatively, a threaded rod 318 can be threaded onto the outer baffle 3131. A small baffle 317 is provided at one end of the threaded rod 318 adjacent to the limiting surface of the outer baffle 3131. The back of the small baffle 317 is hinged to the threaded rod 318. By turning the threaded rod 318, the front of the small baffle 317 is made to fit against the outer wall of the cylindrical section 2.

[0072] Axial reinforcement is achieved by using an axial limiting fixture 4 to reinforce the cylindrical section 2. The axial limiting fixture 4 includes a hook 41, an adjusting screw 42, and a connecting plate 43. One end of the adjusting screw 42 is hinged to the hook 41, and the other end is hinged to the connecting plate 43. Four sets of the axial limiting fixture 4 are arranged circumferentially around the cylindrical section 2. Two sets are arranged on one side of the longitudinal centerline of the vehicle load-bearing frame 1, with one set positioned relatively along the longitudinal centerline towards the front of the cylindrical section 2 and the other set positioned relatively behind the vehicle load-bearing frame 1. The other two sets are arranged on the other side of the longitudinal centerline of the vehicle load-bearing frame 1, with one set relatively along the longitudinal centerline towards the front of the cylindrical section 2 and the other set positioned relatively behind the vehicle load-bearing frame 1. Each set of axial limiting fixtures 4 has hooks 41 that are attached to the top of the cylindrical section 2, i.e., the top of the cylindrical section 2 is inserted into the groove of the hook 41. A rubber buffer layer is provided on the inner surface of the groove of the hook 41, which can effectively absorb vibration and impact during transportation and avoid damage caused by rigid collision between the cylindrical section 2 and the axial limiting fixture 4. The connecting plate 43 is bolted to the bolt hole 14 on the side of the vehicle bearing frame 1. The adjusting screw 42 is a structure consisting of at least two connecting rods connected in series by a threaded connection, and its length can be adjusted as needed by threaded engagement. The axial limiting fixture 4 ensures that the axial displacement of the cylindrical section 2 during transportation is controlled within 1mm, further ensuring transportation stability and reliability.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
