[0002] Mining vehicles, such as large-scale mining dump trucks and ore transporters, are key equipment in mining and transportation operations. They usually have the characteristics of strong load-bearing capacity, large size, and complex structure, especially the engine, which is the core of its power. Moreover, mining vehicles have extremely high requirements for reliability and durability due to long-term high-load operation in harsh environments. The engines of mining vehicles need to be inspected regularly. In order to conduct a comprehensive inspection of the engine, the traditional engine inspection platform usually installs the engine on a rotatable bracket for inspection, which is convenient for adjusting the angle of the engine to fully expose all parts of the engine.

[0003] Traditional engines usually use rigid starting and braking when adjusting the engine maintenance angle. Since the engine of a mining vehicle is large in size and heavy in weight, it is easy to cause impact on the engine and the maintenance platform, increasing the difficulty of maintenance and potential safety risks. Therefore, in order to enable the maintenance angle and braking to be flexibly adjusted during the maintenance of the mining vehicle engine, an engine maintenance platform for a mining vehicle is proposed.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] (1) In order to solve the problem that the engine maintenance platform cannot smoothly adjust the angle when repairing the mining vehicle engine, resulting in additional impact on the engine and the maintenance platform, the present invention can transmit the torque transmitted by the drive motor to the main shaft in a flexible manner by setting a drive component and a brake component, and can apply a flexible braking force to the main shaft, thereby realizing flexible starting and braking of the main shaft, effectively avoiding the problem of easy impact in traditional engine maintenance;

[0017] (2) wherein, by setting a driving assembly, during driving, the driving disc presses the driving friction disc against the driven friction disc through a transmission spring, and the driving force of the driving motor is transmitted to the main shaft through the friction force between the driving friction disc and the driven friction disc for transmission. During the pressing process, the friction force between the driving friction disc and the friction surface gradually increases, and then the torque transmitted by the driving friction disc to the main shaft gradually increases, and the driving main shaft slowly starts to rotate, thereby realizing the flexible start of the main shaft;

[0018] (3) wherein, by providing a brake assembly, during braking, the brake block gradually clamps the driven friction disc from both sides of the driven friction disc, the friction force between the brake groove and the friction ring gradually increases, the main shaft is braked by the friction force between the brake groove and the friction ring, the rotation speed of the main shaft is slowly and gradually reduced, and flexible braking of the main shaft is achieved;

[0019] (4) In addition, when switching between driving and braking, the driving assembly and the braking assembly are connected by a connecting plate. The two moving directions of the connecting plate realize the switching between braking and driving. When the connecting plate moves, it drives the movement of the reversing gear, thereby driving the movement of the push plate and the pressing plate. The driving friction disc and the driven friction disc are pressed tightly together while the brake block and the driven friction disc are loosened. The brake block clamps the driven friction disc and disconnects the driving friction disc from the driven friction disc, thereby realizing the separate control of the driving assembly and the braking assembly.

When the brake block 413 is disconnected from the driven friction disk 502, the pressing plate 409 moves toward the driven friction disk 502 under the elastic force of the brake spring 410. In order to avoid the interference of the brake block 413 on the driven friction disk 502, the pulling block 412 can limit the extension distance of the brake block 413 under the elastic force of the brake spring 410, thereby ensuring that the brake block 413 is completely disconnected from the driven friction disk 502. The brake block 413 is fixedly connected to the pressing plate 409, and a brake groove 414 is provided on the brake block 413.

[0041] In addition, the driven structure 5 includes a main shaft 501 and a driven friction disc 502. The main shaft 501 is rotatably connected to the adjustment box 2, and the driven friction disc 502 is fixedly connected to the main shaft 501.

Torque can be transmitted between the transmission friction disc 306 and the driven friction disc 502 through friction force. A friction ring 504 is provided on the circumference of the driven friction disc 502. Brake blocks 413 are located on both sides of the driven friction disc 502. When the brake blocks 413 clamp the driven friction disc 502 from both sides, the driven friction disc 502 can no longer rotate, thereby fixing the main shaft 501 in the adjusted position.

A threaded rod 13 is rotatably connected inside the adjusting box 2, and a driven bevel gear 14 is fixedly connected to the threaded rod 13. The driven bevel gear 14 is meshingly connected to the driving bevel gear 12.

[0043] The connecting plate 311 is fixedly connected with a threaded sleeve 313 , and the threaded sleeve 313 is threadedly connected to the threaded rod 13 .

[0045] A secondary shaft 16 is rotatably connected to the secondary support 15 , and a fixing frame 17 is fixedly connected between the secondary shaft 16 and the main shaft 501 .

[0046] In specific use, when the mining vehicle is inspected and repaired, the engine is fixed on the fixing frame 17, and the output end of the adjusting motor 10 drives the rotating shaft 11 and the active bevel gear 12 to rotate, thereby driving the driven bevel gear 14 and the threaded rod 13 to rotate, and the threaded rod 13 drives the threaded sleeve 313 and the connecting plate 311 to move along the flower axis 302, and the connecting plate 311 moves in a direction away from the driven structure 5, and the guide sleeve 312 moves along the limiting guide rod 401 with the connecting plate 311, thereby driving the movement of the moving plate 418, and then driving the slider 1 403 to move in a direction away from the slider 2 404, and the movement of the slider 1 403 is in the active The rack 415, the driven rack 416 and the reversing gear 417 drive the slider 2 404 to move, so that the slider 2 404 and the slider 1 403 move away from each other. The L-shaped connecting rod 406 and the push plate 407 move along the guide column 408 under the action of the connecting rod 405. The push plate 407 pushes the pressing plate 409 through the brake spring 410, thereby driving the brake block 413 to clamp the driven friction disc 502 from both sides of the driven friction disc 502. Under the friction force of the brake groove 414 and the friction ring 504, the driven friction disc 502 is locked and fixed, thereby fixing the engine at a certain position for maintenance work.

[0047] When it is necessary to inspect other parts of the engine, the engine is rotated at a certain angle, and the driving motor 6 is started. The output end of the driving motor 6 drives the driving wheel 7 to rotate, and the driving wheel 7 drives the driven wheel 8 to rotate through the belt 9, thereby driving the driving shaft 301 to rotate, and the sleeve 303 rotates with the driving shaft 301. The adjusting motor 10 is started in the reverse direction, and the output end of the adjusting motor 10 drives the threaded sleeve 313 to move along the flower shaft 302 in the opposite direction through the rotating shaft 11 and the threaded rod 13, thereby driving the brake block 413 to move toward both sides of the driven friction disk 502, so that the brake block 413 releases the driven friction disk 502, and the driven friction disk 502 can rotate. At the same time, the connecting plate 311 The sleeve 303 and the push plate 305 are driven to move along the flower axis 302, and the push plate 305 moves toward the direction close to the driven structure 5. The push plate 305 pushes the transmission friction plate 306 through the transmission spring 308, so that the transmission friction plate 306 gradually sticks to the driven friction plate 502. During the sticking process, the friction force between the transmission friction plate 306 and the friction surface 503 gradually increases, so that the torque transmitted to the driving main shaft 501 by the driving shaft 301 gradually increases, so that the driving main shaft 501 slowly starts to rotate. After the friction force between the transmission friction plate 306 and the driven friction plate 502 increases to a certain extent, the driving shaft 301 and the main shaft 501 rotate synchronously, thereby realizing the flexible start of the main shaft 501;

[0048] When it is necessary to stop the rotation, the output end of the adjustment motor 10 rotates in the opposite direction, thereby driving the transmission friction disc 306 to disengage from the driven friction disc 502, and the transmission of the drive shaft 301 no longer drives the driven friction disc 502 to rotate through the transmission friction disc 306. At the same time, the brake block 413 gradually clamps the driven friction disc 502 from both sides of the driven friction disc 502. During the clamping process, the friction force between the brake groove 414 and the friction ring 504 gradually increases, thereby driving the main shaft 501 to brake slowly. After the friction force between the brake block 413 and the driven friction disc 502 increases to a certain extent, the friction force between the brake groove 414 and the friction ring 504 locks the driven friction disc 502, so that the main shaft 501 is fixed, thereby fixing the engine at the adjusted angle, thereby achieving flexible braking of the main shaft 501.
