In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] In addition, the term "same" and the like do not mean that the components must be absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between the components is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0026] Please refer to Figures 1-4 The utility model provides a technical scheme: a new energy mine truck portal frame, including two symmetrical distribution's support board 1, two support board 1 one end is connected with the mine truck's frame, the other end extends upwards, install the connecting frame 2 between two support board 1, the outer surface opposite sides of connecting frame 2 are all installed with the connecting plate 3, and the opposite ends of connecting plate 3 are connected with the top of two support board 1 respectively, and the elastic support structure 4 is installed between the opposite ends of two connecting plate 3 and two support board 1, and the elastic support structure 4 is used to slow down the vibration of the rear suspension of the cab.

[0027] The technical scheme; support board 1 is inverted L type, and connecting frame 2 and connecting plate 3 are inverted U type, and the ends of connecting plate 3 contact with the horizontal plates of two support board 1.

[0028] When the cab of the mine truck is in the falling state, the connecting frame 2 and the connecting plate 3 provide additional support for the rear suspension of the cab, and when the mine truck changes due to load or drives on rough road, the rear suspension of the cab will produce excessive vibration and displacement during driving, and the connecting frame 2 and the connecting plate 3 can disperse and withstand the impact and vibration from the road. In addition, the connecting frame 2 and the connecting plate 3 are usually made of high-strength steel or alloy steel, which has good corrosion resistance, strong wear resistance and certain elastic deformation capacity, and the connecting frame 2 and the connecting plate 3 are inverted U type, which can absorb and consume vibration energy to a certain extent. This buffering effect helps to further reduce the vibration and displacement of the rear suspension of the cab, and the elastic support structure 4 is installed between the opposite ends of the two connecting plates 3 and the two support plates 1, and the vibration generated by the rear suspension of the cab can be damped through the elastic support structure 4.

[0029] Wherein, the rear overhang of the cab is provided with additional support by the connecting frame 2 and the connecting plate 3, and the connecting frame 2 and the connecting plate 3 are usually made of high-strength steel or alloy steel and have a certain elastic deformation capacity, and the connecting frame 2 and the connecting plate 3 are both inverted U-shaped and can absorb and consume vibration energy to a certain extent, which helps to reduce the vibration and displacement of the rear overhang of the cab, and the elastic support structure 4 is installed between the two ends of the two connecting plates 3 and the two support plates 1, which can reduce the vibration of the rear overhang of the cab, thereby improving the driving experience and safety of the driver.

[0030] In the embodiment, the elastic support structure 4 includes two connecting blocks 41, a connecting rod 42, two movable plates 43, a mounting frame 44, and two damping members 45. The two connecting blocks 41 are respectively installed on the opposite surfaces of the two connecting plates 3. The connecting rod 42 is connected to the opposite surfaces of the two connecting blocks 41 at both ends. One end of each of the two movable plates 43 is sleeved on the opposite ends of the connecting rod 42. The two damping members 45 are symmetrically installed on the top surface of the support plate 1. One end of the damping member 45 is connected to the top surface of the support plate 1, and the other end extends upward. The mounting frame 44 is connected to the top end of the damping member 45 at both ends. The other end of each of the two movable plates 43 is connected to the mounting frame 44.

[0031] When the rear overhang of the cab encounters excessive vibration, the vibration will be transmitted along the structure, first affecting the connecting frame 2 and the connecting plate 3 connected thereto, and then the vibration continues to be conducted to the two movable plates 43. The movable plate 43 acts as an intermediary to further transmit vibration energy to the mounting frame 44 and the two damping members 45. The two damping members 45 can effectively absorb and weaken the transmitted vibration, thereby significantly reducing the vibration amplitude of the rear overhang of the cab and ensuring the stability of the cab and the comfort of the ride.

[0032] In the embodiment, the damping member 45 includes a mounting cylinder 451, a pressure pipe 452, a damping spring 453, and a limiting block 454. The closed end of the mounting cylinder 451 is connected to the mounting frame 44, and the open end extends downward. The upper end of the pressure pipe 452 is located in the mounting cylinder 451 and connected to the top surface of the inner wall of the mounting cylinder 451. The lower end of the pressure pipe 452 extends outward. The limiting block 454 is sleeved on the middle lower end of the pressure pipe 452. The damping spring 453 is connected to the top surface of the inner wall of the mounting cylinder 451 and the top surface of the limiting block 454 at both ends.

[0033] When the vibration acts on the damping member 45, the pressure tube 452 drives the mounting cylinder 451 to contract inwardly, at the same time, the damping spring 453 also contracts, and in the process, the two movable plates 43 and the mounting frame 44 connected thereto synchronously descend around the connecting rod 42 as the rotation center. Once the damping member 45 effectively absorbs the vibration energy, the damping spring 453 and the pressure tube 452 will cooperate to reset the mounting cylinder 451, the two movable plates 43 and the mounting frame 44 to the initial state.

[0034] In the embodiment, the upper hanging ring 5 is arranged on the top surface of the closed end of the mounting cylinder 451, the lower hanging ring 6 is arranged on the lower end of the pressure tube 452, the connecting cylinder 7 is arranged on the outer side of each of the two connecting plates 3, the fixed seat 8 is arranged on the top surface of the support plate 1 on the opposite sides, the lower hanging ring 6 is located between the connecting cylinder 7 and the fixed seat 8, and the upper hanging ring 5, the mounting frame 44, the lower hanging ring 6, the connecting cylinder 7 and the fixed seat 8 are connected by bolts.

[0035] When the damping member 45 is damaged, the bolt can be rotated to remove the damping member 45 for maintenance or replacement.

[0036] In the embodiment, the stress plate 9 is arranged between the two movable plates 43, and the stress plate 9 is used to disperse the pressure of the cab.

[0037] The rear suspension of the cab is in contact with the stress plate 9, and when the rear suspension of the cab vibrates or displaces, the vibration is transmitted to the stress plate 9, so as to disperse the vibration of the cab.

[0038] In the embodiment, the first threaded hole 10 is arranged on each of the two movable plates 43, the second threaded hole 11 matched with the first threaded hole 10 is arranged on the opposite sides of the stress plate 9, and the threaded rod is screwed in the first threaded hole 10 and the second threaded hole 11.

[0039] When the rear suspension of the cab displaces during driving, the stress plate 9 is subjected to wear. With the increase of the use time of the stress plate 9, the degree of wear is gradually increased. The damaged stress plate 9 is removed by the threaded rod, so as to be replaced by a new part. After replacement, the new stress plate 9 is reinstalled in place by the threaded rod.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
