Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement.

[0029] Example 1: The embodiment of the present invention provides a multi-level anti-collision trackless rubber-wheeled vehicle for mining, comprising a vehicle chassis 1, a driver's cabin 2 and a cargo hold 3 are provided on the upper surface of the vehicle chassis 1, a set of impact deceleration devices are provided on the left and right sides of the vehicle chassis 1, and the impact deceleration devices are used to decelerate the trackless rubber-wheeled vehicle after a collision occurs, a first protective plate 4 is provided on the front and rear sides of the vehicle chassis 1, a plurality of buffer rods 5 are fixedly connected to the front and rear side walls of the vehicle chassis 1, the first protective plate 4 is fixedly connected to the movable end of the buffer rod 5, and a mounting is fixedly connected to the lower surface of the vehicle chassis 1. The base plate 6 has several groups of impact support devices 7 installed on the lower surface of the mounting base plate 6. The impact support devices 7 are evenly distributed on the front and rear of the mounting base plate 6. The first protective plate 4 is fixedly connected to the side wall of the vehicle chassis 1 with several trigger rods 8. The trigger rod 8 connected to the first protective plate 4 on the front side is corresponding to the impact support device 7 located at the rear of the mounting base plate 6. The trigger rod 8 connected to the first protective plate 4 on the rear side is corresponding to the impact support device 7 located at the front of the mounting base plate 6. The trigger rod 8 slides along the front and rear directions through the outer side wall of the corresponding impact support device 7.

[0030] The principles and beneficial effects of the above technical solution are:

[0031] By setting up the impact deceleration device, when the rubber-tyred trackless vehicle collides on the front side or the rear side, the impact on the vehicle body (vehicle chassis 1, driver's cabin 2 and cargo compartment 3) is reduced, thereby reducing the deformation of the vehicle body, and at the same time, the vehicle is decelerated to avoid secondary collision and secondary injury to the people in the vehicle, thereby improving the safety of the trackless rubber-tyred vehicle during use.

[0032] By disposing the first protection plate 4 and the plurality of groups of impact support devices 7, when the rubber-tyred trackless vehicle is impacted from the side of the vehicle, the plurality of groups of buffer rods 5 are first used to reduce the impact on the vehicle body, thereby reducing the degree of damage to the vehicle body and reducing the probability of the vehicle rolling over. At the same time, through the transmission action of the trigger rod 8, the impact support device 7 located on the opposite side of the impact (for example, if the front side of the vehicle is impacted, the opposite side of the impact is the rear side of the vehicle) is triggered to provide auxiliary support to the vehicle chassis 1, thereby improving the stability of the vehicle, further reducing the probability of the vehicle rolling over in the event of a side collision accident, and improving the safety of the rubber-tyred trackless vehicle when it is impacted.

[0033] Example 2: On the basis of Example 1, a control cavity 9 is provided inside the vehicle chassis 1, and a plurality of buffer rods 2 10 are fixedly connected to the left and right side walls of the vehicle chassis 1. The impact deceleration device includes a second protective plate 11, which is fixedly connected to the movable end of the buffer rod 2 10. The second protective plate 11 is also fixedly connected to a plurality of groups of parallel connecting rods 12 on the side wall of the second protective plate 11 close to the vehicle chassis 1. The connecting rod 12 slides through the side wall of the control cavity 9 in the left and right directions. The end of the connecting rod 12 away from the second protective plate 11 is fixedly connected to a control block 13. The control block 13 is slidably connected in the control cavity 9 in the left and right directions. A spring 14 is fixedly connected between the side wall of the control block 13 away from the connecting rod 12 and the inner wall of the control cavity 9. The lower bottom surface of the control cavity 9 is provided with a mounting groove 15 connected to the outside world. An auxiliary deceleration component moving in the up and down direction is installed in the mounting groove 15. The control block 13 is used to control the lifting and lowering of the auxiliary deceleration component. The auxiliary deceleration component is used to decelerate the trackless rubber-tyred vehicle after a collision occurs.

[0034] Preferably, a slope 16 is provided on the side of the lower bottom surface of the control block 13 away from the connecting rod 12, and the height of the slope 16 away from the connecting rod 12 is higher than the height of the slope 16 close to the connecting rod 12. The mounting groove 15 includes a first step section 151 and a second step section 152. The first step section 151 is located above the second step section 152, and the cross-sectional area of the first step section 151 is larger than the cross-sectional area of the second step section 152. The auxiliary deceleration assembly includes a control block 17. A slope 18 matching the slope 16 is provided on the upper surface of the control block 17. A spring 19 is fixedly connected between the control block 17 and the upper top surface of the second step section 152. The lower end of the control block 17 is fixedly connected to a connecting column 20, the lower end of the connecting column 20 is fixedly connected to a force transmission block 21, and the lower end of the force transmission block 21 is fixedly connected to a bulldozer 22.

[0035] The principles and beneficial effects of the above technical solution are:

[0036] When the rubber-tyred trackless vehicle collides at the front and rear sides, the impact force on the second protection plate 11 is first buffered by the buffer rod 2 10. At the same time, the second protection plate 11 moves toward the vehicle chassis 1 under the action of the impact force, so that the control block 13 compresses the spring 14. Through the cooperation of the inclined surface 16 and the inclined surface 2 18, the control block 2 17 moves downward in the mounting groove 15, so that the bulldozer 22 contacts the ground. As the vehicle body continues to move, soil gradually accumulates in the bulldozer 22. Through the cooperation of the force transmission block 21 and the second step section 152, the vehicle body is decelerated, the braking distance of the vehicle body after the collision is shortened, and the probability of a secondary collision is reduced.

[0037] When the severity of the collision accident is relatively low (no damage is caused to the vehicle body that is sufficient to affect its mobility and the vehicle body is ensured to have sufficient safety performance), the staff manually cleans the soil in the bulldozer 22, and at the same time releases enough space for the second protective plate 11 to rebound. Under the action of spring 14 and spring 2 19, the impact deceleration device can automatically reset, so that the trackless rubber-tyred vehicle can recover its autonomous mobility after only simple treatment by the personnel on the vehicle, thereby facilitating the trackless rubber-tyred vehicle to be driven to the maintenance area for inspection and maintenance by itself, without having to wait for maintenance personnel to arrive at the accident site for maintenance, thereby improving the handling efficiency after the collision accident occurs and saving maintenance resources.

[0043] The principles and beneficial effects of the above technical solution are:

[0044] When the side of the rubber-tyred trackless vehicle is hit, the impact on the first protection plate 4 is first buffered by the buffer rod 1 5. As the first protection plate 4 moves toward the vehicle chassis 1, the trigger rod 8 squeezes the starting rod 50, thereby pushing the trigger block 49 to move toward the support column 25. Through the cooperation of the inclined surface 4 53 and the inclined surface 56, the two sliding blocks 55 are moved away from each other, thereby causing the limit block 2 58 to leave the bottom of the limit block 1 44. Under the action of the spring 3 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 hit, improving the posture stability of the vehicle after being hit from the side, and reducing the probability of the vehicle rolling over.

[0045] 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 multiple 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.

[0046] As the support column 25 moves downward, the rack 39 drives the gear 1 40 to rotate, and at the same time, 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, realizing 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 support stability of the auxiliary support frame 30.

[0047] When the severity of the collision accident is low, the threaded rod 62 is driven to rotate by starting the driving motor 61, thereby causing the threaded block 63 to move 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, the two limit blocks two 58 are moved closer to each other under the action of the spring five 57, 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 a single action of starting the driving motor 61. The control is simple and convenient for operation by personnel on the trackless rubber-tyred vehicle.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
