Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: an anti-derailment mechanism for coal conveying vehicle, comprising a transport plate 1, two fixed seats 2 are installed on both sides of the bottom of the transport plate 1, rollers 3 are rotatably installed inside the fixed seats 2, tracks 4 adapted to the rollers 3 are arranged on both sides of the bottom of the transport plate 1, a mounting frame 5 is arranged at the bottom of the transport plate 1 through a mounting assembly 9, and anti-derailment components 6 are arranged on both sides of the mounting frame 5;

[0021] The anti-slip assembly 6 includes a support seat 61, an adjusting column 62, a movable plate 63 and a limit piece 64. Threaded plates are slidably installed on both sides of the bottom of the mounting frame 5. Two support seats 61 are fixedly installed on the bottom of the mounting frame 5. Adjustment columns 62 are rotatably installed inside the two support seats 61, and the surfaces of the adjustment columns 62 are threadedly installed with the internal threads of the movable plate 63. One end of the adjustment column 62 is set inside the track 4, and limit pieces 64 for fixing the roller 3 are set on both sides of the mounting frame 5.

[0022] The limiting member 64 includes a threaded rod 641, a first adjusting nut 642 and a friction block 643. The threaded rods 641 are threadedly installed on both sides of the mounting frame 5. The first adjusting nut 642 is fixedly installed on the adjacent ends of the two threaded rods 641. The friction block 643 used to fit with the roller 3 is installed on the end of the threaded rod 641 away from the first adjusting nut 642.

[0023] In this embodiment, the length of the anti-slip component 6 is adjusted according to the distance between different rails 4, and the movable plate 63 is driven to slide by rotating the adjusting column 62. The movable plate 63 moves in the mounting frame 5 close to the side groove of the rail 4, so that the movement of the transport plate 1 has a better anti-rollover effect. When the transport plate 1 needs to be fixed, the first adjusting nut 642 is rotated to drive the threaded rod 641 to rotate, and the threaded rod 641 is installed with the internal thread of the mounting frame 5, thereby driving the friction block 643 to fit with the roller 3, which can achieve a limiting effect.

[0024] The movable plate 63 further comprises a sliding member 7, which comprises a groove 71, a shock absorber 72, a floating block 73 and a pulley 74. The top of the movable plate 63 is provided with a groove 71 for the floating block 73 to slide.

The pulley 74 will drive the floating block 73 to move in the groove 71, and the shock absorber 72 is set for rebound, thereby enhancing the sliding property.

[0026] The surfaces of the two adjustment columns 62 are integrally machined with second adjustment nuts 8;

The mounting frame 5 is slidably provided with a mounting bolt 94, and the surface of the insertion rail 93 is provided with a mounting hole 92 adapted to the mounting bolt 94.

[0029] It is worth noting that the insertion rail 93 at the top of the mounting frame 5 is snap-fitted with the insertion groove 91 at the bottom of the transport plate 1, and the mounting bolts 94 are threadedly installed through the mounting holes 92 on the top of the mounting plate and the surface of the insertion rail 93, so that the mounting frame 5 can be loaded and unloaded, which is convenient for disassembly and maintenance of the anti-derail mechanism.

[0030] This device adjusts the length of the anti-slip component 6 according to the distance between different rails 4, and drives the moving plate 63 to slide by rotating the adjusting column 62. The moving plate 63 moves in the mounting frame 5 close to the side groove of the rail 4, so that the movement of the transport plate 1 can better prevent rollover. When the transport plate 1 needs to be fixed, the first adjusting nut 642 is rotated to drive the threaded rod 641 to rotate, and the threaded rod 641 is installed with the internal thread of the mounting frame 5, thereby driving the friction block 643 to fit with the roller 3, which can achieve a limiting effect. When the transport plate 1 tilts, the pulley 74 slides on the surface of the rail 4 to prevent the moving plate 63 from directly contacting the rail 4. The pulley 74 will drive the floating block 73 to move in the groove body 71, and the shock absorber 72 is set to rebound, thereby enhancing the sliding property.
