[0002] Dump trucks for mining are widely used in large mines for transporting earth and stone materials. In view of the topographical features of some mining areas, sometimes it is necessary for the mining trucks to drive along specific routes. The kinetic energy recovery of new energy mining trucks under the working conditions of going uphill and downhill can reduce energy consumption. Therefore, new energy dump trucks are more and more widely used. At the same time, based on the consideration of environmental protection and energy conservation, various new energy vehicles such as new energy trucks and new energy excavators are also widely used.

[0003] Pantographs are widely used in electrified railway systems, and their function is to supply power to trains. The traditional pantograph mainly consists of a pantograph support and a pantograph power supply system.

The pantograph power supply system is also electrically connected to the power supply line and continuously contacts the power supply line during the running of the vehicle body, so as to transmit the power provided by the power supply line to the vehicle body. At present, many mining enterprises apply the technology of electrified railway systems to new energy vehicles. In a new energy dump truck for mining, the pantograph is installed on the new energy dump truck for mining through a pantograph support, and the pantograph and the pantograph support continuously transmit the power of the power supply line to the new energy dump truck for mining. At present, the pantograph support of new energy mining dump trucks is mainly welded by high-strength alloy steel pipes to ensure its stability and durability under the harsh working conditions in mining areas.

[0031] Specifically, at the connection between the column 113 and the bottom beam 111, a second reinforcing plate 115 is provided which is respectively connected to the column 113 and the bottom beam 111.

[0035] In this embodiment, the support main body 11 further includes an intermediate diagonal brace 124. The intermediate diagonal brace 124 is inclined relative to the column 113, and both ends of the intermediate diagonal brace 124 are respectively connected to two spaced columns 113. Specifically in this embodiment, there are two intermediate diagonal braces 124. It can be understood that the corresponding number of intermediate diagonal braces 124 can be set according to the number of columns 113. Specifically in this embodiment, the intermediate diagonal brace 124 is connected to the column 113 by welding.

[0036] Specifically, the first reinforcing plate 110 is also connected to one end of the intermediate diagonal brace 124 close to the upper support 13, and the third reinforcing plate 121 is also connected to one end of the intermediate diagonal brace 124 close to the bottom beam 111.

[0037] In this embodiment, there are two support crossbeams 131, bottom beams 111, first connecting crossbeams 117, second connecting crossbeams 118, third connecting crossbeams 119, and intermediate diagonal braces 124, and four columns 113. The four columns 113 are arranged in a rectangle to form a frame structure. One end of two columns 113 is connected to one bottom beam 111, and the other ends are respectively connected to two support crossbeams 131. One end of the other two columns 113 is connected to the other bottom beam 111, and the other ends are respectively connected to two support crossbeams 131. The two columns 113 connected to one support crossbeam 131 are also connected to both ends of a first connecting crossbeam 117, and the two columns 113 connected to the other support crossbeam 131 are also connected to both ends of another first connecting crossbeam 117. The two columns 113 connected to one bottom beam 111 are also connected to both ends of a second connecting crossbeam 118 and both ends of a third connecting crossbeam 119, and the two columns 113 connected to the other bottom beam 111 are also connected to both ends of another second connecting crossbeam 118 and both ends of another third connecting crossbeam 119. The two columns 113 connected to one support crossbeam 131 are also connected to both ends of an intermediate diagonal brace 124, and the two columns 113 connected to the other support crossbeam 131 are also connected to both ends of another intermediate diagonal brace 124.

[0038] In this embodiment, one end of the bottom beam 111 extends out of the outside of the column 113. The support body 11 further includes a side diagonal brace 126. The side diagonal brace 126 is inclined relative to the column 113, and one end of the side diagonal brace 126 is connected to the part of the bottom beam 111 that extends out of the outside of the column 113, and the other end is connected to the middle part of the column 113. Specifically, in this embodiment, there are two side diagonal braces 126 only on one side of the support body 11. Specifically, in this embodiment, the side diagonal brace 126 is connected to the column 113 and the bottom beam 111 by welding.

[0039] Specifically, the fourth reinforcing plate 122 is also connected to one end of the side diagonal brace 126.

[0040] For the pantograph support of this embodiment, the connection strength is increased by the first reinforcing plate 110, the second reinforcing plate 115, the third reinforcing plate 121, and the fourth reinforcing plate 122, which can enhance the overall structural strength of the pantograph support. In this way, the structural strength of the pantograph support can be ensured even when the structure of the support body 111 is relatively simple. At the same time, the structure can be simplified, the material used can be reduced, and the cost can be lowered.

[0041] In this embodiment, the support body 11 further includes a backing plate 128, and the backing plate 128 is arranged on the side of the bottom beam 111 away from the column 113. Since the mounting parts of the support body 11 on the vehicle body are not in the same plane, setting the backing plate 128 can facilitate the installation. Specifically, the backing plate 128 can be connected to the bottom beam 111 by welding.

[0042] It can be understood that some or all of the joints of the pantograph support in this embodiment can also be connected by other methods than welding, such as threaded connection, riveting, etc.

[0043] The present utility model also provides a new energy vehicle. Please refer to Figure 2 , a new energy vehicle in an embodiment includes a vehicle body, a pantograph assembly, and the above pantograph support. The pantograph assembly is installed on the upper support 13 of the pantograph support, and the support body 11 is installed on the vehicle body. In this way, during operation, the hand pantograph system is electrically connected to the external power supply line, and the power of the external power supply line can be transmitted to the vehicle body through the pantograph support, enabling the new energy vehicle to continuously operate. In an embodiment, the new energy vehicle can be a new energy dump truck.

[0044] In this embodiment, the vehicle body includes a chassis and a frame 51 connected to the chassis. The bottom beam 111 of the support body 11 of the pantograph support is fixedly connected to the frame 51. More specifically, the bottom beam 111 is connected to the longitudinal beam of the frame 51. By installing the pantograph support on the frame 51, the installation position of the pantograph support can be lowered. On the one hand, the hoisting difficulty can be reduced when installing the pantograph assembly, and the pantograph system can be hoisted onto the installation platform without using large-scale aerial hoisting equipment, facilitating the installation and maintenance of the pantograph assembly; on the other hand, the center of gravity of the whole vehicle can be reduced to balance the center of mass of the whole vehicle. Specifically, in this new energy vehicle, the pantograph assembly is basically side by side with the cab in the height direction, so that the operator can walk from the cab to the pantograph support to repair the pantograph assembly, which is very convenient.

[0045] Specifically, the pantograph support is installed at the front end of the frame 51, which is also convenient for the installation and maintenance of the pantograph support. More specifically, the side diagonal brace 126 is located on one side of the front end of the frame 51. The front end of the frame 51 refers to the side close to the front end of the new energy vehicle.

[0046] Specifically, one end of the bottom beam 111 facing the front end of the frame 51 extends out of the outside of the column 113 of the support body 11.

The side diagonal brace 126 is inclined relative to the column 113 of the support body 11, and one end of the side diagonal brace 126 is connected to the part of the bottom beam 111 extending out of the outside of the column 113 of the support body 11, and the other end is connected to the middle of the column 113 of the support body 11.

[0047] In this embodiment, the pantograph assembly includes a chassis 61, a moving frame 63, a guide rod 65, and a bow head 67. The chassis 61 is fixedly connected to the support cross beam 131 of the upper support 13. The moving frame 63 is movably disposed on the chassis 61. One end of the guide rod 65 is connected to a damper 631 on the moving frame 63, and the other end is connected to the bow head 67. The bow head 67 is used for sliding contact with an external power supply line. When the new energy vehicle is running, it drags the bow head 67 to slide along the external power supply line. The power of the external power supply line is transmitted to the vehicle body through the bow head 67, the guide rod 65, and the conductive wire supported by the moving frame 63, the upper support 13, and the support body 11, enabling the vehicle body to continuously operate.

[0048] Specifically, a guide rail 611 is provided on the chassis 61, and the moving frame 63 is movably engaged with the guide rail 611.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
