Technical Field

[0001] This invention relates to the technical field of load transfer of longitudinal beams in mining dump trucks, and more particularly to a load transfer mechanism for longitudinal beams in dump trucks. Background Technology

[0002] Mining dump trucks are a type of off-highway dump truck, used in off-highway field locations such as large open-pit mines and water conservancy projects to transport coal and sand. In civil engineering, they are often used in conjunction with excavators, loaders, belt conveyors, and other construction machinery to form loading, transporting, and unloading production lines for earthwork, sand, gravel, and bulk materials.

[0003] Because the cargo box of mining dump trucks is heavy, and when fully loaded, the lower longitudinal beam of the cargo box and the longitudinal beam of the frame cannot be completely fitted due to manufacturing issues. When the vehicle is running, the bumpy conditions cause uneven stress on the longitudinal beam of the frame. The huge load can cause problems such as cracking at the connection of the longitudinal beam of the frame. Summary of the Invention

[0043] Example 1

[0044] Reference Figures 1-5 A schematic diagram of the overall structure of a longitudinal beam load transfer mechanism for a dump truck is provided, including a main component 100, comprising a frame assembly 101, a contact component 102 that abuts against the frame assembly 101, and a conversion component 103 connected to the contact component 102; and a transmission component 200, comprising a drive component 201 connected to the conversion component 103 and a receiving component 202 connected to the drive component 201. The frame assembly 101 presses against the contact component 102, while the conversion component 103 converts the force of the contact component 102 into a rotational force, which is then transmitted to the receiving component 202 by the drive component 201, and finally transmitted outward through the receiving component 202.

[0045] Specifically, the frame assembly 101 includes a frame cargo box 101a, a frame longitudinal beam 101b disposed under the frame cargo box 101a, and a limiting groove beam 101c connected to the frame longitudinal beam 101b. The abutment assembly 102 includes an abutment plate 102a that abuts against the inclined surface of the frame cargo box 101a, an output component 102b connected to the abutment plate 102a, and a toggle component 102c connected to the output component 102b. Frame longitudinal beams 101b are provided on both sides of the bottom end of the frame cargo box 101a. One side of the rod of the frame longitudinal beam 101b is rotatably connected to the frame cargo box 101a through a shaft. The inclined surface of the frame cargo box 101a abuts against the inclined surface of the abutment plate 102a. By continuously placing materials inside the frame cargo box 101a, the mass of the frame cargo box 101a can be increased while the inclined surface squeezes the abutment plate 102a.

[0046] Furthermore, the output component 102b includes an L-shaped connecting rod 102b-1 connected to the contact plate 102a, a movable groove 102b-2 formed under the L-shaped connecting rod 102b-1, and a rotating rod 102b-3 disposed within the movable groove 102b-2. The actuating component 102c includes an actuating rod 102c-1 disposed outside the rotating rod 102b-3, and an output block 102c-2 connected to the end of the actuating rod 102c-1. The output block 102c-2 slides inside the limiting groove beam 101c. An L-shaped connecting rod 102b-1 is fixedly connected to one side of the contact plate 102a. Movable grooves 102b-2 are formed on both sides of the bottom end of the L-shaped connecting rod 102b-1. A rotating rod 102b-3 is fixedly connected inside each of the two movable grooves 102b-2. A lever 102c-1 is rotatably connected to the outer side of the lever 102b-3. Output blocks 102c-2 are rotatably connected to the ends of the levers 102c-1 on both sides. The output blocks 102c-2 on both sides are slidably connected to the inside of the limiting groove beam 101c. When the contact plate 102a descends, it also drives the L-shaped connecting rod 102b-1 to descend. In addition, by limiting the output blocks 102c-2 with the limiting groove beam 101c, the L-shaped connecting rod 102b-1 descends and drives the levers 102c-1 on both sides to separate to both sides. This causes the output blocks 102c-2 on both sides to move to both sides and abut against the side of the longitudinal beams 101b on both sides of the frame. This achieves the conversion of part of the vertical load of the cargo box 101a on the longitudinal beams 101b of the frame into a lateral load.

[0047] Operation process: By continuously placing materials inside the cargo box 101a, the weight of the cargo box 101a increases, and its inclined end tilts. This tilting causes the contact plate 102a to be pressed against the inclined surface. As the contact plate 102a descends, the L-shaped connecting rod 102b-1 also descends. In addition, the output block 102c-2 is limited by the limiting groove beam 101c, which causes the L-shaped connecting rod 102b-1 to descend. At the same time, the two actuating rods 102c-1 on both sides will separate to the sides, thereby causing the two output blocks 102c-2 on both sides to move to the sides and abut against the side of the longitudinal beams 101b on both sides. This achieves the conversion of part of the vertical load of the cargo box 101a on the longitudinal beams 101b of the frame into a lateral load.

[0048] Example 2

[0049] Reference Figures 1-6 This embodiment differs from the first embodiment in that: the conversion assembly 103 includes a conversion rod 103a connected to the output block 102c-2, and a spiral groove 103b formed outside the conversion rod 103a; wherein, the conversion rod 103a slides within the body of the frame longitudinal beam 101b, and the drive assembly 201 includes a sleeve 201a connected to the conversion rod 103a, and a limiting rod 201b disposed within the sleeve 201a; wherein, the limiting rod 201b matches the spiral groove 103b, and the ends of the output blocks 102c-2 that are separated are all fixedly connected to the conversion rod 103a, and spiral grooves 103b are formed on the outer sides of both ends of the conversion rods 103a, and the two conversion rods 103a on both sides are slidably connected to the two sides of the frame longitudinal beam 101b. Inside beam 101b, sleeves 201a are rotatably connected to the side of the longitudinal beams 101b on both sides of the frame that are separated from each other, located at the position of conversion rod 103a. Limiting rods 201b are fixedly connected inside sleeves 201a. Limiting rods 201b match spiral grooves 103b. When the output block 102c-2 moves to both sides, it also drives the rotating rods 102b-3 on both sides to move outward and pass through the longitudinal beams 101b on both sides of the frame. During its movement, the spiral grooves 103b on the outside of conversion rods 103a guide the limiting rods 201b, so that sleeves 201a and limiting rods 201b rotate along the trajectory of spiral grooves 103b, thereby achieving the purpose of converting translational force.

[0050] Furthermore, the receiving component 202 includes a pressing rod 202a connected to the sleeve 201a, and an adapter groove 202b formed on the pressing rod 202a; wherein, the adapter groove 202b matches the rotating rod 102b-3, the sleeve 201a is connected to the longitudinal beam 101b of the frame, and the pressing rod 202a is fixedly connected to one end of each sleeve 201a. The adapter groove 202b is formed on the surface of the pressing rod 202a at the sleeve 201a. The adapter groove 202b matches the rotating rod 102b-3. When the sleeve 201a rotates, it will also drive the pressing rod 202a to rotate. In addition, the adapter groove 202b on the pressing rod 202a allows the conversion rod 103a to pass through the pressing rod 202a, and achieves the purpose of not affecting the rotation of the pressing rod 202a.

[0051] Specifically, it also includes a pressing component 300; the pressing component 300 includes a positioning component 301 connected to the receiving component 202, and a buffer component 302 connected to the positioning component 301; the buffer component 302 abuts against the side of the frame assembly 101, the positioning component 301 is for supporting the buffer component 302, and the buffer component 302 is for fixing the frame assembly 101.

[0052] Furthermore, the positioning component 301 includes a slide rod 301a and a baffle 301b disposed at the end of the slide rod 301a; the buffer component 302 includes an output spring 302a disposed outside the slide rod 301a and a compression plate 302b connected to the output spring 302a; wherein, the output spring 302a is connected to the compression rod 202a, the compression plate 302b is connected to the slide rod 301a, the upper sides of the compression rods 202a on both sides are slidably connected to the slide rod 301a, the ends of the slide rods 301a on both sides are fixedly connected to the baffle 301b, the ends of the slide rods 301a on both sides are fixedly connected to the compression plate 302b, the compression plates 302b on both sides abut against the cargo box 101a of the vehicle frame, and the slide rods 301a on both sides are fixedly connected to the baffle 301b. An output spring 302a is sleeved on the outer side of 01a between the extrusion plate 302b and the extrusion rod 202a. When the extrusion rod 202a moves, it drives the extrusion plates 302b on both sides to abut against the chassis cargo box 101a. The curved side of the extrusion plate 302b can be easily pushed by the chassis cargo box 101a, thereby causing the extrusion plate 302b and the sliding rod 301a to slide on the extrusion rod 202a. At the same time, the extrusion plate 302b will also compress the output spring 302a. Meanwhile, the rebound force of the output spring 302a will also push the extrusion plate 302b to fix the sides of the chassis cargo box 101a, thereby achieving the purpose of making the chassis cargo box 101a more stable during the movement of the dump truck.

[0053] The rest of the structure is the same as in Example 1.

[0054] Operation process: As the output block 102c-2 moves to both sides, it also drives the rotating rods 102b-3 on both sides to move outward and pass through the longitudinal beams 101b of the frame on both sides. During its movement, the spiral groove 103b on the outer side of the conversion rod 103a guides the limiting rod 201b, allowing the sleeve 201a and the limiting rod 201b to rotate along the trajectory of the spiral groove 103b. As the sleeve 201a rotates, it also drives the extrusion rod 202a to rotate. Then, using the fitting groove 202b on the extrusion rod 202a, the conversion rod 103a can pass through the extrusion rod 202a, achieving the effect of not... The purpose of influencing the rotation of the extrusion rod 202a is to cause the extrusion plates 302b on both sides to come into contact with the cargo box 101a while the extrusion rod 202a moves. The curved sides of the extrusion plates 302b can be easily pushed by the cargo box 101a, causing the extrusion plates 302b and the slide rod 301a to slide on the extrusion rod 202a. At the same time, the extrusion plates 302b will also compress the output spring 302a. The rebound force of the output spring 302a will also push the extrusion plates 302b to fix the sides of the cargo box 101a, thereby achieving the purpose of making the cargo box 101a more stable during the movement of the dump truck.

[0055] Example 3

[0056] Reference Figures 1-7 This embodiment differs from the above embodiments in that it also includes a reset component 400. The reset component 400 includes a pressing component 401 disposed under the abutting component 102 and a lifting component 402 connected to the pressing component 401. The pressing component 401 is used to provide power to the lifting component 402, and at the same time, the pressing component 401 can also drive the abutting component 102 to reset.

[0057] Specifically, the pressing assembly 401 includes a pressing plate 401a, a pressing rod 401b connected to the pressing plate 401a, and a return spring 401c disposed outside the pressing rod 401b. The pressing rod 401b slides in the middle of the limiting groove beam 101c. The bottom end of the pressing plate 401a is fixedly connected to the pressing rod 401b, which slides in the middle of the limiting groove beam 101c. The return spring 401c is sleeved on the outer side of the pressing rod 401b. Under the aforementioned L-shaped connecting rod 102b-1... As the load is lowered, the pressing plate 401a is also pressed. At the same time, the pressing plate 401a drives the pressing rod 401b to lower, which in turn squeezes the return spring 401c. When the load inside the cargo box 101a is unloaded, the return force of the return spring 401c will reset. During the reset process, the pressing plate 401a and the pressing rod 401b will reset, and then the pressing plate 401a will drive the L-shaped connecting rod 102b-1 to reset, thereby achieving the purpose of resetting the aforementioned abutment component 102.

[0058] Furthermore, the lifting assembly 402 includes a rocker arm 402a connected to the pressing rod 401b, a support rod 402b connected to the rocker arm 402a, and a support plate 402c connected to the end of the support rod 402b; wherein, the support plate 402c is connected to the longitudinal beam 101b of the frame, the bottom end of the pressing rod 401b is rotatably connected to the rocker arm 402a, one side of the rocker arm 402a is fixedly connected to the support rod 402b, and both ends of the support rod 402b are rotatably connected to the support plate 402c, and both ends support... The top of the support plate 402c is fixedly connected to the bottom of the longitudinal beams 101b on both sides of the frame. When the pressing rod 401b descends, it also presses one end of the rocker arm 402a. At the same time, the support rod 402b and the support plate 402c support the middle side of the rocker arm 402a, thus forming a lever principle. This makes it easier for the rocker arm 402a to be pressed up by the pressing rod 401b to support the cargo box 101a of the frame, thereby further reducing the vertical load on the longitudinal beams 101b of the frame.

[0059] The rest of the structure is the same as in Example 2.

[0060] Operation process: As the L-shaped connecting rod 102b-1 descends, it also presses the pressing plate 401a. Simultaneously, the pressing plate 401a, while driving the pressing rod 401b downwards, also compresses the return spring 401c. As the pressing rod 401b descends, it also presses one end of the rocker arm 402a. At the same time, the support rod 402b and the support plate 402c support the middle side of the rocker arm 402a, thus forming a lever principle, allowing the rocker arm 402a to... When 02a is pressed up by the pressing rod 401b to support the chassis cargo box 101a, it is easier to use. When the load inside the chassis cargo box 101a is unloaded, the return force of the return spring 401c will reset. During the reset process, the pressing plate 401a and the pressing rod 401b will reset, and then the L-shaped connecting rod 102b-1 will reset through the pressing plate 401a. This achieves the reset of the above-mentioned abutting component 102 and reduces the vertical load on the chassis longitudinal beam 101b.
