[0029] The upper portion of support sliding seat 425 is provided with support arm 426, and the outer wall of support sliding seat 425 and support arm 426 is hingedly connected by hinge mechanism 427; The inner side wall of support arm 426 is fixedly installed with connecting block 428 by rotating rod.

[0030] The outer wall of installation L type guard 421 is provided with guide arc sliding hole 429, and the inside of guide arc sliding hole 429 is slidably connected with connecting sliding rod 4210, and the other end of connecting sliding rod 4210 is fixedly connected to the outer wall of connecting block 428.

[0031] One side of installation L type guard 421 is provided with hook type support plate 4211, and hook type support plate 4211 is welded to the bottom of dump truck support side frame 1; The bottom of hook type support plate 4211 is fixedly installed with fixing bolt, and extends to the inside of dump truck support side frame 1; The inner wall bottom of hook type support plate 4211 is fixedly installed with adjusting hydraulic cylinder 4212 by connecting seat, the top of adjusting hydraulic cylinder 4212 is fixedly installed with fixed connection steel plate 4213 by mounting column seat, and fixed connection steel plate 4213 is welded to the outer wall of dump truck hopper, and fixed connection steel plate 4213 is welded to the outer wall of dump truck hopper, the other end of support arm 426 is fixedly connected to the outer wall of fixed connection steel plate 4213, the outer wall of fixed connection steel plate 4213 is fixedly installed with fixing bolt, which is arranged on the outer side of support arm 426, for reinforcing the connection between fixed connection steel plate 4213 and the hopper.

[0032] Further, the hinge mechanism 427, the connecting sliding rod 4210 and the guide arc sliding hole 429 are provided, the flexible adjustment of the support arm 426 is realized, the operator can adjust the angle and position of the support arm 426 according to the actual position of the dump truck hopper and the support demand, so that the support arm 426 can better fit the hopper and provide effective support, which can meet the support demand of different models and sizes of dump truck hoppers, and the adjusting hydraulic cylinder 4212 pushes the fixed connection steel plate 4213 to move upward, so that the fixed connection steel plate 4213 closely fits the outer wall of the dump truck hopper, and the fixing bolt is used for reinforcement, which enhances the stability of the support, prevents the hopper from tilting or shaking during maintenance, and reduces the risk of accidents during maintenance.

[0033] In use, first, the trapezoidal fixed shell 2 is set on the outer wall of the dump truck support side frame 1, and the trapezoidal fixed shell 2 is preliminarily fixed on the dump truck support side frame 1 through the cooperation of the threaded hole and the fixed screw 3, and then the fixed nut 31 is sleeved for further reinforcement, so as to ensure that the trapezoidal fixed shell 2 remains stable during maintenance. At the same time, a control switch is arranged on one side of the trapezoidal fixed shell 2 for controlling the work of each component in the buffer support assembly 4.

[0034] Further, when the dump truck hopper needs to be repaired and maintained and is placed on the supporting device, the gravity of the hopper first acts on the buffer support part 41. The hopper is placed on the non-slip pad 418, and the non-slip convex points 419 on the top of the non-slip pad 418 increase the friction with the bottom of the hopper, preventing the hopper from sliding. At this time, the gravity of the hopper is transmitted to the support column 414 in turn through the non-slip pad 418, the fixed top plate 417, the damper 416 and the fixed bottom plate 415. If the hopper is impacted by external force during placement or maintenance, the damper 416 will play its buffering and damping role, absorbing and dispersing the impact force and reducing the damage to the hopper and the maintenance equipment. At the same time, the telescopic hydraulic rod 413 will adjust the extension according to the gravity and impact force of the hopper, and the support column 414 is movably penetrated and extended to the inside of the bottom of the U-shaped support plate 411, providing stable support force for the hopper. When the impact force is large, the telescopic hydraulic rod 413 further extends, increasing the extension length of the support column 414, thereby enhancing the support ability of the hopper.

[0035] Further, on the basis of the preliminary support provided by the buffer support part 41 to the vehicle hopper, the support part 42 further supports and reinforces the vehicle hopper, ensuring the stability of the vehicle hopper during the maintenance process. The operator controls the working of the adjusting hydraulic cylinder 4212 through the control switch, and the extension and retraction of the adjusting hydraulic cylinder 4212 drives the fixed connection steel plate 4213 to move up and down. Since the fixed connection steel plate 4213 is welded to the outer wall of the vehicle hopper of the dump truck and is fixedly connected to the other end of the support arm 426, the movement of the fixed connection steel plate 4213 will drive the support arm 426 to rotate around the hinge mechanism 427, thereby adjusting the angle of the support arm 426 so that it can better fit the outer wall of the vehicle hopper and provide effective support. After the angle of the support arm 426 is adjusted, the connecting block 428 is fixed to the inner side wall of the support arm 426 through the rotating rod, and the sliding rod 4210 slides in the guide arc sliding hole 429 to provide stable support and guidance for the support arm 426. At the same time, the support sliding seat 425 slides in the sliding groove 424 of the limiting sliding seat 423, further ensuring the stability and flexibility of the support arm 426 during the angle adjustment process. The triangular support plate 422 is fixedly installed at the bottom of the L-shaped guard plate 421 and the outer wall of the trapezoidal fixed shell 2, enhancing the overall stability of the support part 42 and preventing the support arm 426 from shaking or tilting during the support process. The outer wall of the fixed connection steel plate 4213 is fixedly installed with a fixed bolt, which is arranged outside the support arm 426 and used to reinforce the connection between the fixed connection steel plate 4213 and the vehicle hopper, ensuring the firm connection between the support part 42 and the vehicle hopper and improving the reliability of the support, thereby supporting the vehicle hopper and preventing the vehicle hopper from tilting or shaking during the maintenance process.

[0036] Through the control switch arranged on one side of the trapezoidal fixed shell 2, the operator can conveniently control the working of the telescopic hydraulic rod 413, the adjusting hydraulic cylinder 4212 and other components, realizing accurate control over the buffer support and support process.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features.
