[0020] Embodiment 1: An embodiment of the present invention provides a multi-level anti-collision mine trackless rubber-tyred vehicle, which includes a vehicle chassis 1. A cockpit 2 and a cargo compartment 3 are arranged on the upper surface of the vehicle chassis 1. A set of impact deceleration devices are arranged on both the left and right sides of the vehicle chassis 1. The impact deceleration devices are used to decelerate the trackless rubber-tyred vehicle after a collision occurs. A first protection plate 4 is arranged on both the front and rear sides of the vehicle chassis 1. A number of first buffer rods 5 are fixedly connected to the front and rear side walls of the vehicle chassis 1. The first protection plate 4 is fixedly connected to the movable ends of the first buffer rods 5. An installation substrate 6 is fixedly connected to the lower surface of the vehicle chassis 1. A number of groups of impact support devices 7 are installed on the lower surface of the installation substrate 6. The impact support devices 7 are evenly distributed in the front and rear parts of the installation substrate 6. A number of trigger rods 8 are fixedly connected to the side wall of the first protection plate 4 close to the vehicle chassis 1. The trigger rods 8 connected to the front first protection plate 4 are arranged corresponding to the impact support devices 7 located at the rear of the installation substrate 6. The trigger rods 8 connected to the rear first protection plate 4 are arranged corresponding to the impact support devices 7 located at the front of the installation substrate 6. The trigger rods 8 slide through the outer side walls of the corresponding impact support devices 7 in the front-rear direction.

[0021] The principle and beneficial effects of the above technical solution are as follows: Through the setting of the impact deceleration device, when the trackless rubber-tyred vehicle collides on the front side and the rear side, while reducing the impact on the vehicle body (vehicle chassis 1, cockpit 2 and cargo compartment 3) and thus reducing the deformation of the vehicle body, the vehicle is decelerated to avoid a secondary collision and cause secondary injury to the personnel in the vehicle, improving the safety during the use of the trackless rubber-tyred vehicle.

[0022] Through the provision of the first protection plate 4 and several sets of impact support devices 7, when the trackless rubber-tyred vehicle is impacted from the side of the vehicle, first, several buffer rods one 5 reduce the impact on the vehicle body, reducing the degree of damage to the vehicle body and simultaneously reducing the probability of the vehicle rolling over. At the same time, through the transmission of the trigger rod 8, the impact support devices 7 located on the opposite side of the impact (for example, if the front side of the vehicle is collided, the opposite side of the impact is the rear side of the vehicle) are triggered to assist in supporting the vehicle chassis 1, thereby improving the stability of the vehicle and further reducing the probability of the vehicle rolling over when a collision occurs on the side of the vehicle, and improving the safety of the trackless rubber-tyred vehicle when it is collided.

[0023] Embodiment 2: On the basis of Embodiment 1, a first control cavity 9 is provided inside the vehicle chassis 1. A number of buffer rods two 10 are fixedly connected to the left and right side walls of the vehicle chassis 1. The impact deceleration device includes a second protection plate 11. The second protection plate 11 is fixedly connected to the movable ends of the buffer rods two 10. A number of groups of parallel connecting rods 12 are also fixedly connected to the side wall of the second protection plate 11 close to the vehicle chassis 1. The connecting rods 12 slide through the side wall of the first control cavity 9 in the left and right directions. One end of the connecting rod 12 far from the protection plate 11 is fixedly connected to a first control block 13. The first control block 13 is slidably connected in the first control cavity 9 in the left and right directions. A first spring 14 is fixedly connected between the side wall of the first control block 13 on the side far from the connecting rod 12 and the inner wall of the first control cavity 9. An installation groove 15 communicating with the outside is provided on the lower bottom surface of the first control cavity 9. An auxiliary deceleration assembly that moves in the up and down direction is installed in the installation groove 15. The first control block 13 is used to control the lifting of the auxiliary deceleration assembly, and the auxiliary deceleration assembly is used to decelerate the trackless rubber-tyred vehicle after a collision occurs.

[0024] Preferably, a first inclined surface 16 is provided on the lower bottom surface of the first control block 13 on the side far from the connecting rod 12. The height of the first inclined surface 16 on the side far from the connecting rod 12 is higher than the height of the first inclined surface 16 on the side close to the connecting rod 12. The installation groove 15 includes a first stepped section 151 and a second stepped section 152. The first stepped section 151 is located above the second stepped section 152. The cross-sectional area of the first stepped section 151 is larger than the cross-sectional area of the second stepped section 152. The auxiliary deceleration assembly includes a second control block 17. A second inclined surface 18 that cooperates with the first inclined surface 16 is provided on the upper surface of the second control block 17. A second spring 19 is fixedly connected between the second control block 17 and the upper top surface of the second stepped section 152. A connecting column 20 is fixedly connected to the lower end of the second control block 17. A force transmission block 21 is fixedly connected to the lower end of the connecting column 20. A bulldozer blade 22 is fixedly connected to the lower end of the force transmission block 21.

[0025] The principle and beneficial effects of the above technical solution are as follows: When a collision occurs on the front side and the rear side of the trackless rubber-tyred vehicle, first, the impact force on the second protection plate 11 is buffered by the buffer rod two 10. At the same time, under the action of the impact force, the second protection plate 11 moves towards the direction close to the vehicle chassis 1, so that the control block one 13 compresses the spring one 14. Through the cooperation of the inclined plane one 16 and the inclined plane two 18, the control block two 17 moves downward in the installation groove 15, so that the bulldozer blade 22 contacts the ground. As the vehicle body continues to move, soil gradually accumulates in the bulldozer blade 22. Through the cooperation of the force transmission block 21 and the second step section 152, the deceleration of the vehicle body is realized, the braking distance of the vehicle body after the collision occurs is shortened, and the probability of a secondary collision is reduced.

[0026] When the severity of the collision accident is relatively low (without causing damage to the vehicle body sufficient to affect its mobility and ensuring that the vehicle body has sufficient safety performance), the staff manually cleans the soil in the bulldozer blade 22, and at the same time releases enough space for the second protection plate 11 to rebound. Under the action of the spring one 14 and the spring two 19, the impact deceleration device can be automatically reset, so that the trackless rubber-tyred vehicle only needs simple treatment by the personnel in the vehicle to restore its independent mobility, and then it is convenient to drive the trackless rubber-tyred vehicle to the maintenance area for maintenance by itself without waiting for the maintenance personnel to arrive at the accident site for maintenance, thus improving the handling efficiency after the collision accident occurs and saving maintenance resources.

[0030] Preferably, a first limiting block 44 is fixedly connected to the upper end of the support column 25. A conical surface 45 is arranged on the outer edge of the first limiting block 44. The control assembly includes a control box 46, which is fixedly connected to the inner top surface of the protective housing 23. A release hole 47 is arranged on the lower side wall of the control box 46. A second control cavity 48 is arranged inside the lower side wall of the control box 46.

[0031] Preferably, a third limiting block 60 is also fixedly connected to the lower part of the support column 25.

A threaded block 63 is threadedly connected to the threaded rod 62. The threaded block 63 is located below the third limiting block 60.

[0032] The principle and beneficial effects of the above technical solution are as follows: When the side of the trackless rubber-tyred vehicle is collided, first, the first buffer rod 5 buffers the impact received by the first protection plate 4. As the first protection plate 4 moves towards the vehicle chassis 1, the trigger rod 8 squeezes the starting rod 50, and then pushes the trigger block 49 to move towards the support column 25. Through the cooperation of the fourth inclined surface 53 and the fifth inclined surface 56, the two sliding blocks 55 move away from each other, and then the second limiting block 58 moves away from below the first limiting block 44. Under the action of the third spring 27, the support column 25 moves downward until the support block 26 contacts the ground, providing support for the vehicle, thereby offsetting the tendency of the vehicle to roll over after being impacted, improving the attitude stability of the vehicle after being impacted on the side, and reducing the probability of the vehicle rolling over.

[0033] As the support column 25 moves downward, under the action of the linkage assembly, the control rod 36 moves toward the direction close to the support column 25, so that under the action of the limit rod 38, the auxiliary support frame 30 moves toward the direction close to the support column 25. Finally, the auxiliary support frame 30, the support column 25 and the ground form a plurality of triangular support structures, which further improves the support stability of the auxiliary support assembly, so that the auxiliary support assembly can maintain the posture stability of the trackless rubber-tyred vehicle under greater impact force.

[0034] As the support column 25 moves downward, the rack 39 drives the gear 1 40 to rotate, and the gear 1 40 drives the gear 2 41 to rotate, so that the second locking rod 43 rotates toward the first locking rod 42, and finally achieves the effect of the first locking rod 42 and the second locking rod 43 engaging with each other, thereby achieving the fixation of the control rod 36 in the front and rear directions, and at the same time improving the connection rigidity between the support column 25 and the control rod 36, thereby improving the supporting stability of the auxiliary support frame 30.

[0035] When the severity of the collision accident is low, the threaded rod 62 is driven to rotate by starting the driving motor 61, so that the threaded block 63 moves upward, and the limit block three 60 is lifted by the threaded block 63, thereby realizing the recovery action of the support column 25. Through the cooperation of the conical surface 45 and the inclined surface three 59, when the limit block one 44 passes between the two limit blocks two 58 from bottom to top, the two limit blocks two 58 can automatically move away from each other, so that the limit block one 44 passes between the two limit blocks two 58 smoothly. After the limit block one 44 completely reaches the top of the limit block two 58, under the action of the spring five 57, the two limit blocks two 58 approach each other, and the limiting effect on the limit block one 44 is realized again, thereby realizing the effect of automatically resetting the auxiliary support assembly by only starting the driving motor 61. The control is simple and convenient for personnel on the trackless rubber-tyred vehicle to operate.
