Description

Technical Field

[0001] This utility model relates to the field of precision goods transportation technology, and in particular to an anti-collision structure for large cargo transportation equipment. Background Technology

[0002] "Special ultra-heavy and precision items" typically refer to critical equipment or components that are extremely heavy (hundreds to thousands of tons or even tens of thousands of tons), oversized, structurally precise, valuable, and irreplaceable or difficult to repair. The transportation, installation, and maintenance of such items involve extremely high technical difficulty and risks, requiring the support of specialized technical systems.

[0003] Existing transport equipment is mostly fixed and cannot be adapted to equipment of different sizes, especially lacking the flexibility to handle ultra-wide equipment. Height adjustment relies on simple jacks or pads, which are inaccurate, cumbersome to operate, and cannot maintain dynamic stability during transport. Therefore, we propose an anti-collision structure for large cargo transport equipment. Utility Model Content

[0004] The main objective of this invention is to provide an anti-collision structure for large cargo transport equipment, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A collision avoidance structure for large cargo transport includes a trailer. Several air springs are symmetrically arranged on the upper surface of the trailer. Several hydraulic buffers are arranged between the air springs on the upper surface of the trailer. Guide holes are opened at the four corners of the upper surface of the trailer. A damping rubber pad is arranged at the bottom of the guide hole. A base plate is arranged at the top of the air springs and the hydraulic buffers. Guide posts are arranged at the four corners of the bottom surface of the base plate.

[0006] Preferably, the guide post is shaped and sized to fit the guide hole, the guide post is disposed inside the guide hole and slides and extends with the guide hole, and the tops of the several air springs and several hydraulic dampers are fixedly connected to the bottom surface of the base plate.

[0007] By adopting the above technical solutions: air springs can withstand greater loads and provide more stable support; through air pressure regulation, various adjustments to pressure and hardness can be achieved; at the same time, hydraulic dampers effectively absorb the impact energy in mechanical motion through the flow resistance of hydraulic oil, reducing equipment wear, extending service life, reducing mechanical vibration and impact; fewer parts are required, maintenance is relatively simple, and maintenance costs are reduced.

[0008] Preferably, two sets of linear guide rails are symmetrically arranged on the upper surface of the base plate. Two sets of guide rail sliders are slidably connected to the upper surfaces of the two sets of linear guide rails. A movable plate is arranged on the upper surface of the two sets of guide rail sliders. A hydraulic cylinder is arranged at each of the four corners of the upper surface of the movable plate. A top plate is arranged at the top of each hydraulic cylinder. Two sets of fixing blocks are symmetrically arranged on the upper surface of the top plate. A threaded rod is rotatably connected between the two sets of fixing blocks. A bevel gear is arranged at one end of the threaded rod. A slide rail is arranged on both sides of the threaded rod on the upper surface of the top plate. A sliding block is arranged on the upper surface of each of the two sets of slide rails. A threaded sleeve is inserted through the periphery of the threaded rod. A base plate is arranged on the upper surface of the threaded sleeve and the sliding block. A contour block is arranged on the upper surface of the base plate.

[0009] Preferably, a servo motor is provided on the bottom surface of the top plate, and a bevel gear is provided at the output end of the servo motor. The bevel gear meshes with the bevel gear. The threaded rod is threadedly engaged with the threaded sleeve. A drive assembly matching the linear guide rail and the guide rail slider is provided on the bottom surface of the movable plate.

[0010] By adopting the above technical solution, two sets of parallel linear guides are fixed to the upper surface of the base plate, providing a high-precision, high-rigidity guiding reference. The guide rail slider precisely matches the linear guide, ensuring smooth, low-friction movement of the moving plate along the guide direction. The drive assembly provides power and precisely controls the position of the moving plate. This allows for a wide range of adjustment of the distance between the two sets of moving plates, thus flexibly adapting to precision equipment bases of different widths. Preferably, a contour plate is provided on the left side of the upper surface of the base plate, and hydraulic cylinders are provided at the four corners of the upper surface of the contour plate. A top plate is provided at the top of each hydraulic cylinder. Two sets of slide rails are symmetrically arranged on the upper surface of the top plate. Two sets of fixing blocks are provided on the upper surface of the top plate between the two sets of slide rails. A screw is rotatably connected between the two sets of fixing blocks. A bevel gear is provided at one end of the screw. Sliding blocks are provided on the upper surfaces of the two sets of slide rails. Threaded sleeves are inserted into the circumferential side of the screw. A servo motor is provided on the bottom surface of the top plate. A bevel gear is provided at the output end of the servo motor. A base plate is provided on the upper surface of the threaded sleeve and the two sets of sliding blocks. A contour block is provided on the upper surface of the base plate. A baffle is provided on one side of the contour block.

[0011] Preferably, the fourth bevel gear meshes with the third bevel gear, the screw is threaded into the second threaded sleeve, and the sides of the second profile block, the baffle, and the first profile block are all provided with damping rubber pads.

[0012] By adopting the above technical solution: when the equipment comes into contact with the side of the molding block or the baffle due to vibration, impact or inertial force, or even slight collision, the damping rubber pad, as a flexible medium, can effectively absorb the impact energy. The rubber material has a high coefficient of friction, which can increase the static friction between the equipment and the support / limiting surface, further suppressing the extremely small relative sliding that may occur on the support surface. The baffle is made of rigid material.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Air springs provide high load-bearing capacity and low-frequency foundation vibration isolation, while hydraulic buffers efficiently absorb mid-to-high-frequency impact energy, forming a synergistic vibration reduction mechanism. A precision guiding system with guide columns, guide holes, and damping rubber pads ensures that the vibration reduction process is strictly limited to the vertical direction, eliminating the risk of horizontal swaying and torsion, and significantly improving transportation stability. This combination significantly reduces the vibration and impact experienced by heavy-duty precision equipment under complex road conditions, especially suppressing low-frequency vibrations and instantaneous strong impacts, effectively preventing damage to the internal precision structures of the equipment during transportation. Based on the design of linear guides, guide sliders, drive components, and moving plates, the spacing between the two sets of support units can be infinitely adjusted, flexibly adapting to equipment bases of different widths. Hydraulic cylinders one and two, distributed at the four corners, provide high-thrust vertical lifting and rigid self-locking support, meeting the needs for coarse height adjustment, static stability support, and overall leveling. The first and second profile blocks are precisely matched with the shape of the equipment support structure, maximizing the contact area, significantly reducing local pressure, and avoiding equipment deformation or damage caused by stress concentration. The rigid baffle design located on the left side of the second profile block provides strong lateral restraint, effectively resisting the inertial and centrifugal forces generated during transportation, such as turning, ramps, and starting and stopping, completely preventing the overall lateral slippage of the equipment and ensuring absolute safety under extreme working conditions.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-4 This utility model provides a technical solution: A collision avoidance structure for large cargo transport includes a trailer 1. Several air springs 10 are symmetrically arranged on the upper surface of the trailer 1. Several hydraulic buffers 101 are arranged between the air springs 10 on the upper surface of the trailer 1. Guide holes 102 are opened at the four corners of the upper surface of the trailer 1. Damping rubber pads 103 are arranged at the bottom of the guide holes 102. A base plate 2 is arranged at the top of the air springs 10 and the hydraulic buffers 101. Guide posts 20 are arranged at the four corners of the bottom surface of the base plate 2.

[0020] In this embodiment, the shape and size of the guide post 20 are adapted to the guide hole 102. The guide post 20 is set inside the guide hole 102 and slides and extends with the guide hole 102. The tops of several air springs 10 and several hydraulic buffers 101 are fixedly connected to the bottom surface of the base plate 2.

[0021] The above scheme uses the air spring 10 and the hydraulic damper 101 to form a synergistic shock absorption mechanism. The guide column 20, guide hole 102 and damping rubber pad 103 ensure that the shock absorption process is strictly limited to the vertical direction, eliminating the risk of horizontal swaying and torsion, and effectively preventing damage to the internal precision structure of the equipment during transportation.

[0022] In this embodiment, two sets of linear guide rails 201 are symmetrically arranged on the upper surface of the base plate 2. Two sets of guide rail sliders 202 are slidably connected to the upper surfaces of the two sets of linear guide rails 201. A movable plate 203 is arranged on the upper surface of the two sets of guide rail sliders 202. Hydraulic cylinders 204 are arranged at the four corners of the upper surface of the movable plate 203. A top plate 205 is arranged at the top of the hydraulic cylinders 204. Two sets of fixing blocks 206 are symmetrically arranged on the upper surface of the top plate 205. A threaded rod 207 is rotatably connected between the two sets of fixing blocks 206. A bevel gear 208 is arranged at one end of the threaded rod 207. Sliding rods are arranged on both sides of the threaded rod 207 on the upper surface of the top plate 205. The upper surface of each of the two sets of slide rails 209 is provided with a sliding block 210. The threaded rod 207 has a threaded sleeve 211 inserted through its circumference. The upper surface of the threaded sleeve 211 and the sliding block 210 is provided with a base plate 21. The upper surface of the base plate 21 is provided with a contour block 22. The bottom surface of the top plate 205 is provided with a servo motor 23. The output end of the servo motor 23 is provided with a bevel gear 230, which meshes with the bevel gear 208. The threaded rod 207 is threadedly engaged with the threaded sleeve 211. The bottom surface of the moving plate 203 is provided with a drive assembly that matches the linear guide rail 201 and the guide rail slider 202.

[0023] Through the above scheme: the bevel gear 230 at the output end of the servo motor 23 meshes with the bevel gear 208, thereby driving the threaded rod 207 to rotate, which causes the base plate 21 and the top profile block 22 to move, so that it can be adjusted and fixed according to the size of the equipment. The rigid baffle 321 located on the side of the left profile block 320 provides strong lateral constraint force, effectively resisting the inertia generated by turning, ramps, and starting and stopping during transportation.

[0024] It should be noted that by first adjusting the guide rail slider 202 and the linear guide rail 201 through the drive assembly, the moving plate 203 is ensured to move smoothly and with low friction along the guide rail direction, and the position of the moving plate 203 is precisely controlled. This enables a wide range of adjustment of the distance between the two sets of moving plates 203, thereby flexibly adapting to precision equipment bases of different widths. The bevel gear 230 at the output end of the servo motor 23 meshes with the bevel gear 208, thereby driving the threaded rod 207 to rotate, which causes the base plate 21 and the top contour block 22 to move, thus allowing for adjustment and fixation according to the size of the equipment. When the equipment comes into contact with the side of the contour block 320, the baffle 321, and the damping rubber pad 220 on one side of the contour block 220 due to vibration, impact, or inertial force, or even slight collision, the damping rubber pad, as a flexible medium, can effectively absorb the impact energy. The rubber material has a high coefficient of friction, which can increase the static friction between the equipment and the support / limiting surface. Simultaneously, hydraulic cylinders 204 and 30 provide high-thrust vertical lifting and rigid self-locking support, meeting the needs of coarse height adjustment, static stability support, and overall leveling. Air spring 10 provides high load-bearing capacity and low-frequency foundation vibration isolation, which, combined with hydraulic buffer 101, efficiently absorbs medium- and high-frequency impact energy, forming a synergistic vibration reduction mechanism. The precision guiding system, including guide column 20, guide hole 102, and damping rubber pad 103, ensures that the vibration reduction process is strictly limited to the vertical direction, eliminating the risk of horizontal swaying and torsion, and significantly improving transportation stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
