Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to an anti-sway device for mining truck beds. Background Technology

[0002] Mining trucks are core transportation equipment in open-pit mines and large-scale engineering projects. Mine roads are rugged and steep, and uneven material loading (such as differences in block size or off-center loading) can cause the truck bed to sway up and down during operation. The rigid connection between the truck bed and the frame, such as welding, can lead to breakage and damage at the weld points, posing a safety hazard. Therefore, anti-sway devices are needed between the truck bed and the frame to buffer the impact force on the connection points. However, current conventional anti-sway devices use elastic mechanisms in the lateral direction of the truck bed to buffer the kinetic energy of the vertical sway. But these elastic mechanisms on both sides of the truck bed can only buffer the impact force from the swaying; they cannot quickly reduce the amplitude of the sway. When the amplitude of the sway is large, the risk of the mining truck tipping over still exists. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0042] This application provides an anti-sway device for mining truck beds. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 as well as Figure 3 , Figure 1 The anti-sway device for mining truck beds provided in the embodiments of this application, Figure 2 for Figure 1 Cross-sectional view at point CC. Figure 3 This is a schematic diagram of the connection between the frame mounting plate 2 and the anti-sway mechanism 3 provided in the embodiments of this application. Figure 4 This is a schematic diagram of the structure of the carriage mounting plate 1 provided in the embodiment of this application. The anti-sway device includes: carriage mounting plate 1, frame mounting plate 2, anti-sway mechanism 3, and multiple connecting parts 4.

[0043] In this embodiment, the car body mounting plate 1 is used to connect the car body, and the frame mounting plate 2 is used to connect the frame. That is, the anti-sway device for mining truck cars provided in this application embodiment is installed between the car body and the frame of the mining truck.

[0044] The anti-sway mechanism 3 includes a set of lateral anti-sway components 31 symmetrically arranged in the horizontal direction, a set of vertical anti-sway components 32 symmetrically arranged in the vertical direction, and multiple transmission rods 33. The two ends of each transmission rod 33 are rotatably connected to a lateral anti-sway component 31 and a vertical anti-sway component 32, respectively.

[0045] The upper end of each connector 4 is rotatably connected to the carriage mounting plate 1, and the lower end is rotatably connected to a lateral anti-sway component 31;

[0046] Both the lateral anti-sway component 31 and the vertical anti-sway component 32 include sliding members capable of elastic sliding. The connecting member 4 is used to transfer the kinetic energy of the truck bed's vertical swing into the lateral movement of the sliding member in the lateral anti-sway component 31, and to drive the vertical movement of the sliding member in the vertical anti-sway component 32 through multiple transmission rods 33, so that the swaying kinetic energy of the truck bed is jointly canceled and dissipated by the lateral anti-sway component 31 and the vertical anti-sway component 32.

[0047] When the mining truck bed sways, the connecting piece 4 transfers the kinetic energy of the bed's vertical swaying to the sliding piece in the lateral anti-sway assembly 31, causing it to move laterally. Simultaneously, the motion is linked to the sliding piece in the vertical anti-sway assembly 32 via the transmission rod 33, causing it to move vertically. During this movement, kinetic energy is absorbed and dissipated through elastic deformation. This process converts the multi-directional swaying of the bed into the mechanical motion of the anti-sway assembly, and the energy is dispersed through elastic elements, thus jointly counteracting the swaying. This improves vehicle stability and safety, reduces the swaying amplitude of the bed during driving or loading / unloading, prevents material spillage, reduces vehicle structural stress, extends the service life of the bed and frame, and enhances driver comfort and operational safety.

[0048] Please see Figure 3 and Figure 4 In some embodiments, the four corners of the cargo box mounting plate 1 are elastically connected to the frame mounting plate 2 via first elastic members 5. This ensures that the first elastic members 5 are evenly distributed at the four corners. When the cargo box swings, multiple first elastic members 5 undergo compression or stretching deformation, absorbing and dispersing the impact energy generated by the swing. Furthermore, this uniform arrangement ensures that the connection points between the cargo box and the frame are subjected to uniform force, avoiding localized stress concentration and effectively counteracting multi-directional swing. It also enhances the buffering capacity and stability of the anti-sway device, further suppressing cargo box swing; it also improves the durability of the connection parts, reduces the risk of metal fatigue, ensures that the device maintains reliable performance under harsh operating conditions, and reduces maintenance frequency and costs.

[0049] In some embodiments, the side of the frame mounting plate 2 facing the carriage mounting plate 1 may be provided with a first mounting cavity 21, and the first mounting cavity 21 is provided with a plurality of first mounting blocks 22, each of the first mounting blocks 22 being provided with a first mounting hole 221, and each of the first mounting holes 221 being provided with a first guide post 222.

[0050] The side of the carriage mounting plate 1 facing the frame mounting plate 2 is provided with a second mounting cavity 11. The second mounting cavity 11 is provided with a second mounting block 12 that corresponds one-to-one with the first mounting block 22. Each second mounting block 12 is provided with a second mounting hole 121 and each second mounting hole 121 is provided with a second guide post 122.

[0051] The lower end of the first elastic member 5 extends into the first mounting hole 221 and is sleeved on the first guide post 222 in the first mounting hole 221; its upper end extends into the second mounting hole 121 and is sleeved on the second guide post 122 in the second mounting hole 121.

[0052] In this way, the first guide post 121 and the second guide post 122 are respectively embedded in the first mounting hole 22 and the second mounting hole 121, providing linear guidance for the first elastic element 5, preventing the first elastic element 5 from deflecting or twisting during compression or rebound, ensuring that the first elastic element 5 always moves in the preset direction, and optimizing energy absorption efficiency. The structural design of the first mounting cavity 21, the second mounting cavity 11, the first mounting block 22 and the second mounting block 12 also enhances the overall rigidity, reduces additional vibration, extends the service life of the first elastic element 5, maintains the consistency of the anti-sway device performance, and improves the vehicle's adaptability to rough road conditions.

[0053] In some embodiments, each first sliding member 311 has a first hinge seat at its upper end, and the top wall of the second mounting cavity 11 has two second hinge seats. The lower end of each connector 4 is hinged to the first hinge seat, and the upper end is hinged to the second hinge seat.

[0054] In this way, by hinged the upper and lower ends of the connector 4 to the second hinge seat and the first hinge seat respectively, a revolute joint is formed, allowing the connector 4 to rotate freely when the truck bed swings. This smoothly converts the up-and-down swing of the truck bed into the lateral movement of the lateral anti-sway component 31, reducing energy loss due to motion resistance. The hinged design also compensates for installation errors, ensuring smooth transmission; achieves flexible and efficient power transmission to adapt to complex swing angles of the truck bed; and has high kinetic energy conversion efficiency, enabling the lateral anti-sway component 31 and the vertical anti-sway component 32 to respond promptly to swing changes, enhancing the overall anti-sway effect; at the same time, it reduces wear on the connectors and improves the reliability of the device.

[0055] In some embodiments, a central block 23 is provided at the center of the first mounting cavity 21, and a corresponding block 13 is provided at the center of the second mounting cavity 11. The central block 23 is elastically connected to the corresponding block 13 via an auxiliary elastic member 6. This elastic connection between the corresponding block 13 and the central block 23 strengthens the connection between the cargo box mounting plate 1 and the frame mounting plate 2. The auxiliary elastic member 6 connects the central block 23 and the corresponding block 13. When the cargo box swings, the auxiliary elastic member 6 works in conjunction with the first elastic members 5 at the four corners to absorb the swing kinetic energy in the central area, preventing stress concentration at the corners and dissipating energy more evenly. The auxiliary elastic member 6 between the central block 23 and the corresponding block 13 provides additional elastic support, enhancing the overall rigidity and buffering capacity of the device and balancing the force on the central area. The central block 23 also serves as the anchor point for the lateral anti-sway component 31 and the vertical anti-sway component 32, optimizing the power transmission path, preventing excessive deformation of the device's center, improving fatigue resistance, ensuring the cargo box remains stable under heavy loads, and reducing the risk of overall structural deformation.

[0056] Please continue reading. Figure 3 In some embodiments, the lateral anti-sway component 31 includes a left anti-sway component 31a and a right anti-sway component 31b symmetrically arranged, and respectively located on the left and right sides of the central block 23; the vertical anti-sway component 32 includes a front anti-sway component 32a and a rear anti-sway component 32b symmetrically arranged, and respectively located on the front and right sides of the central block 23.

[0057] In this way, the left anti-sway assembly 31a and the right anti-sway assembly 31b handle lateral swaying, while the front anti-sway assembly 32a and the rear anti-sway assembly 32a handle vertical swaying. This symmetrical layout can respond promptly to the swaying of the truck bed, achieving all-round coverage of the swaying direction, improving the uniformity and efficiency of anti-swaying, enhancing the stability of the vehicle when turning, accelerating, or braking, reducing the risk of rollover, and improving operational efficiency. The transmission rod 33 links the lateral and vertical movements, enabling efficient transfer and dissipation of energy among the left anti-sway assembly 31a, the right anti-sway assembly 31b, the front anti-sway assembly 32a, and the rear anti-sway assembly 32b.

[0058] Specifically, both the left anti-sway component 31a and the right anti-sway component 31b of the lateral anti-sway assembly 31 include: a horizontal shaft 312, a first sliding member 311, and a second elastic member 313. The horizontal shaft 312 is fixed within the first mounting cavity 21. The first sliding member 311 is slidably mounted on the horizontal shaft 312. The second elastic member 313 is mounted on the horizontal shaft 312 and located on both sides of the first sliding member 311.

[0059] Among them, one end of the horizontal axis 312 of the left anti-sway component 31a is connected to the left wall of the first mounting cavity 21, and the other end is connected to the left side of the center block 23; one end of the horizontal axis 312 of the right anti-sway component 31b is connected to the right wall of the first mounting cavity 21, and the other end is connected to the right side of the center block 23.

[0060] In this way, the first sliding member 311 is fitted onto the horizontal axis 312 and can slide, while the second elastic members 313 on both sides provide restoring force. When the connecting member 4 transmits kinetic energy, the first sliding member 311 moves laterally to compress the second elastic members 313, converting the oscillating kinetic energy into elastic potential energy and dissipating it. The horizontal axis 312 acts as a guide rail, ensuring smooth movement of the first sliding member 311 and preventing jamming. The lateral anti-sway component 31 uses the horizontal axis 312, the first sliding member 311, and the second elastic members 313 to achieve efficient lateral kinetic energy absorption.

[0061] Both the front anti-sway assembly 32a and the rear anti-sway assembly 32b include: a vertical shaft 322, a second sliding member 321, and a third elastic member 323. The vertical shaft 322 is fixed within the first mounting cavity 21; the second sliding member 321 is slidably sleeved on the vertical shaft 322; and the third elastic member 323 is sleeved on the vertical shaft 322 and located on both sides of the second sliding member 321.

[0062] One end of the vertical shaft 322 of the front anti-sway assembly 32a is connected to the front wall of the first mounting cavity 21, and the other end is connected to the front side of the center block 23. One end of the vertical shaft 322 of the rear anti-sway assembly 32b is connected to the rear wall of the first mounting cavity 21, and the other end is connected to the rear side of the center block 23.

[0063] The second sliding member 321 slides on the vertical shaft 322, and the third elastic member 323 is located on both sides of it. When the transmission rod 33 drives the second sliding member 321 to move vertically, the third elastic member 323 is compressed or stretched to absorb vertical kinetic energy. The vertical shaft 322 ensures accurate guidance of vertical movement. By linking with the lateral anti-sway component 31, multi-directional kinetic energy dissipation is achieved, reducing the up-and-down bumping of the truck bed, protecting the on-board equipment from impact, and improving driver comfort.

[0064] Each first sliding member 311 is rotatably connected to each second sliding member 321 via a transmission rod 33, thereby coupling the movements of the lateral anti-sway component 31 and the vertical anti-sway component 32. Specifically, there can be four transmission rods 33. The front side of the first sliding member 311 on the left anti-sway component 31a is hinged to the left side of the front anti-sway component 32a via a transmission rod 33, and the rear side is hinged to the left side of the rear anti-sway component 32b via a transmission rod 33. The front side of the first sliding member 311 on the right anti-sway component 31b is hinged to the right side of the front anti-sway component 32b via a transmission rod 33, and the rear side is hinged to the right side of the rear anti-sway component 32b via a transmission rod 33.

[0065] When the mining truck passes through a bumpy section, the truck bed swings up and down. The kinetic energy of the swing is transmitted to the two first sliding members 311 of the transverse anti-sway assembly 31 through the connecting member 4, forcing the two first sliding members 311 to slide away from each other along the transverse axis 312. That is, the first sliding member 311 on the left anti-sway assembly 31a slides to the left, and the first sliding member 311 on the right anti-sway assembly 31b slides to the right. In addition, the first sliding member 311 on the left anti-sway assembly 31a compresses the second elastic member 313 on its left side, and the first sliding member 311 on the right anti-sway assembly 31b compresses the second elastic member 313 on its right side. This pair of opposite lateral movements are immediately transmitted through the transmission rod 33 to the two second sliding members 321 of the vertical anti-sway assembly 32, forcing the two second sliding members 321 to slide closer to each other along the vertical axis. That is, the second sliding member 321 on the front anti-sway assembly 32a slides backward, and the second sliding member 321 on the rear anti-sway assembly 32b slides forward. The second sliding member 321 on the front anti-sway assembly 32a compresses the third elastic member 323 on its rear side, and the second sliding member 321 on the rear anti-sway assembly 32a compresses the third elastic member 323 on its front side.

[0066] While the second elastic element 313 and the third elastic element 323 are compressed, the first sliding element 311 on the left anti-sway assembly 31a receives a rightward reaction force from the second elastic element 313 on its left, and the first sliding element 311 on the right anti-sway assembly 31b receives a leftward reaction force from the second elastic element 313 on its right. Furthermore, the lateral kinetic energy of the truck bed's vertical swaying is absorbed by the second elastic element 313 in a compressed manner. Similarly, the second sliding element 321 on the front anti-sway assembly 32a receives a rightward reaction force from the second elastic element 313 on its left, and the first sliding element 311 on the right anti-sway assembly 31b receives a leftward reaction force from the second elastic element 313 on its right. The vertical kinetic energy of the truck bed's vertical swaying is absorbed by the second elastic element 313 in a compressed manner.

[0067] Ultimately, the opposing forces exerted by the second elastic element 313 on the two first sliding elements 311, and the reaction force exerted by the third elastic element 323 on the two second sliding elements 321, can quickly reduce the amplitude of the truck bed's up-and-down swaying.

[0068] In this way, on the one hand, the kinetic energy of a single up-and-down swing is converted into mechanical motion in two orthogonal directions, namely lateral and longitudinal motion. This allows multiple second elastic elements 313 and third elastic elements 323 to work together to dissipate the kinetic energy of the up-and-down swing, thereby improving the efficiency of energy dissipation. On the other hand, dissipating the up-and-down swing "spread out" within a plane increases the damping path and anti-sway efficiency, reduces the amplitude of the truck bed's swing, improves driving stability and comfort, and reduces the impact on the vehicle structure and the loaded materials.

[0069] In some embodiments, the first elastic element 5, the second elastic element 313, the third elastic element 323, and the auxiliary elastic element 6 can all be springs (e.g., coil springs). As standard elastic elements, springs provide linear elastic force, and their characteristics are easily predictable and controllable. In anti-sway devices, springs absorb kinetic energy through compression or stretching and quickly rebound to release energy, achieving efficient energy dissipation. The versatility of springs simplifies component manufacturing and assembly, reducing customization costs. This improves the economy and maintainability of the anti-sway device and extends its overall service life.

[0070] Please combine Figures 1 to 4 The following is an example illustrating the overall working process of the anti-sway device.

[0071] Initial state: The truck bed is kept horizontal, the first elastic element 5, the second elastic element 313 and the third elastic element 323 are in an uncompressed state, and the first sliding element 311 and the second sliding element 321 are in a stationary state.

[0072] Oscillation Occurs: When the mining truck travels on a bumpy road, the truck bed oscillates laterally or vertically, transmitting the kinetic energy of the oscillation to the first elastic member 5 and the connecting member 4 via the truck bed mounting plate 1. The first elastic member 5 is compressed by the oscillation force and then rebounds, with the reaction force of the first elastic member 5 on the truck bed mounting plate 1 offsetting part of the oscillation kinetic energy. Simultaneously, the connecting member 4 transmits the oscillation force to the two first sliding members 311 of the lateral anti-sway assembly 31, forcing the first sliding member 311 on the left anti-sway assembly 31a to move to the left on the horizontal axis 312 and compress the second elastic member 313 on the left side; at the same time, the first sliding member 311 on the right anti-sway assembly 31b moves to the right, compressing the second elastic member 313 on its right side.

[0073] The two first sliding members 311 slide, which in turn, through the four transmission rods 33, pulls the second sliding members 321 on the front anti-sway assembly 32b and the rear anti-sway assembly 32b to move closer to each other. Therefore, the kinetic energy of the car's vertical sway is effectively converted into the elastic potential energy of the second elastic member 313 and the third elastic member 323. The reaction force generated by the compression of the second elastic member 313 and the third elastic member 323 is transmitted back to the car mounting plate 1 through the entire anti-sway mechanism 3 and the connecting member 4, resisting its vertical swaying tendency and thus quickly suppressing the sway.

[0074] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
