[0027] Figure 1 A structural schematic diagram of a mine dump truck platform ladder hanging device 100 provided by the embodiments of the application is shown in FIG. 1. As shown in FIG. 1, the embodiments of the application provide a mine dump truck platform ladder hanging device 100, which comprises a connecting seat 10, a flexible side plate 20, a step 30, and a handrail 40. Figure 1

[0028] The connecting seat 10 is the installation basis of other components and is used to connect with the frame platform 1 of the mine dump truck. The connecting seat 10 comprises a first connecting part 11 and two second connecting parts 12. The first connecting part 11 is used to connect with the frame platform 1, and the two second connecting parts 12 are respectively connected on both sides of the first connecting part 11, for installing other components.

[0029] As an example, the connecting seat 10 is composed of a plate body of metal material which is bent. The middle part of the plate body is the first connecting part 11, and the two end parts of the plate body are bent by 90° to the same side of the first connecting part 11, forming the two second connecting parts 12.

[0030] Further, in order to reduce the weight, the connecting seat 10 can be provided with a weight reduction structure.

[0031] As an example, the weight reduction structure comprises a weight reduction gap 111 provided on the first connecting part 11.

[0032] ​The flexible side plates 20 are used to set the steps 30, and the number of the flexible side plates 20 is at least one pair, and each pair of the flexible side plates 20 includes two flexible side plates 20. When the number is one pair, the upper ends of the two flexible side plates 20 in the pair of the flexible side plates 20 are respectively connected with the two second connecting portions 12 of the connecting seat 10. When the number is more than one pair, the upper ends of the two flexible side plates 20 in the first pair of the flexible side plates 20 are respectively connected with the two second connecting portions 12 of the connecting seat 10, and the lower ends of the two flexible side plates 20 are respectively connected with the upper ends of the two flexible side plates 20 in the second pair of the flexible side plates 20, and so on, and the lower ends of the two flexible side plates 20 in each pair of the flexible side plates 20 are respectively connected with the upper ends of the two flexible side plates 20 in another pair of the flexible side plates 20 which is immediately below.

[0033] The flexible side plates 20 are made of rubber, rubber plastic or other materials with good elasticity, so that the mine dump truck platform ladder hanging device 100 has a certain flexibility, and rigid deformation will not occur when it is subjected to impact and the like, thereby reducing the maintenance cost in the later period. In addition, compared with a chain which also has a certain flexibility but is easy to sway, the flexible side plates 20 can ensure the stability of the mine dump truck platform ladder hanging device 100 when it is used.

[0034] As an example, the number of the flexible side plates 20 is one pair, and the two flexible side plates 20 are both rubber plates, and the upper ends of the two flexible side plates 20 are respectively connected with the two second connecting portions 12 of the connecting seat 10 through fasteners. The connection mode of the fasteners is convenient for maintenance and replacement.

[0035] The flexible side plates 20 can be arranged in a direction inclined to the ground or in a direction perpendicular to the ground.

[0036] As an example, the flexible side plates 20 are arranged in a direction inclined to the ground, so that after the steps 30 are set, the mine dump truck platform ladder hanging device 100 becomes a diagonal ladder, and it is easier for a person to climb up and down the truck platform 1.

[0037] The number of the steps 30 is multiple, and the multiple steps 30 are distributed in the up-down direction, the uppermost step 30 is connected between the two second connecting portions 12 of the connecting seat 10, and the remaining steps 30 are connected between the two flexible side plates 20 on the two sides.

[0038] As an example, the number of the steps 30 is three, including a first step 31 and two second steps 32. The first step 31 is the uppermost step and is connected between the two second connecting portions 12 of the connecting seat 10 by welding. The two second steps 32 are the lower two steps, and the two ends of each second step 32 are respectively connected with the two flexible side plates 20 through fasteners.

[0039] It can be understood that the first pedal 31 can also be connected between the two second connecting parts 12 by fasteners.

[0040] Further, in order to prevent slipping, the surface of the pedal 30 can be provided with an anti-skid structure.

[0041] As an example, the upper surface of the first pedal 31 is provided with a plurality of anti-skid protrusions 311 arranged in an array, and the upper surface of the second pedal 32 is provided with a plurality of rows of anti-skid teeth arranged in positive and negative oblique directions with respect to the length direction.

[0042] Further, in order to reduce the weight, the pedal 30 can be a hollow structure.

[0043] As an example, the first pedal 31 is provided with a plurality of weight-reducing holes corresponding to the plurality of anti-skid protrusions 311. The second pedal 32 includes a rectangular outer frame 321 and a plurality of tooth-shaped grating plates 322 arranged in the outer frame 321, the plurality of tooth-shaped grating plates 322 are arranged in positive and negative oblique directions with respect to the length direction in the outer frame 321, so that the second pedal 32 becomes a hollow structure, and the tooth-shaped edges of each tooth-shaped grating plate 322 constitute anti-skid teeth. The second pedal 32 of the structure not only ensures the stability of the structure, but also reduces the weight and increases the anti-skid performance.

[0044] The number of handrails 40 is at least one, and the handrails 40 can be arranged on the connecting seat 10 or on the flexible side plate 20.

[0045] As an example, the number of handrails 40 is two, each handrail 40 is formed by bending a circular pipe and sealing the two ends with end caps, and the two handrails 40 are connected to the two second connecting parts 12 of the connecting seat 10 by welding.

[0046] The application also provides a mine dump truck, which comprises a vehicle frame platform 1 and the mine dump truck platform ladder hanging device 100.

[0047] As an example, Figure 2 The structure diagram of the mine dump truck platform ladder hanging device 100 provided by the application is connected with the vehicle frame platform 1, as shown in Figure 2 The first connecting part 11 of the connecting seat 10 is connected with the side surface of the vehicle frame platform 1 by fasteners.

[0048] It should be noted that the fasteners in the application can be bolts and nuts or other fastenable structures, which are convenient for maintenance and replacement.

[0049] In summary, the mining dump truck platform ladder hanging device and the mining dump truck provided by the embodiments of the present application have a certain flexibility due to the use of the flexible side plates, rigid deformation does not occur when the mining dump truck platform ladder hanging device is subjected to collision or the like, and the maintenance cost in the later period is reduced; the connection seat, the flexible side plates and the pedal are detachably connected, which facilitates the maintenance and replacement in the later period.

[0050] The above merely provides specific implementation manners of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, and these should be covered in the protection scope of the present application.
