Description

Technical Field

[0001] The utility model relates to the technical field of working condition equipment, in particular to a frame structure of an underground vehicle and a working condition vehicle. Background Art

[0002] When a tunnel and underground vehicle enters a mine cave, due to limited space and terrain, the vehicle frame often needs to be disassembled into multiple parts and then assembled after entering the mine. Currently, the rear outriggers of most vehicles are directly installed on the side of the frame weldment, resulting in a large distance between the rear outriggers and the frame welding joint. During the operation, this structure makes it difficult for the load at the frame welding joint to be quickly transmitted to the ground, leading to easy fatigue damage at this part and reducing the service life.

[0003] In addition, even if the frame is disassembled into multiple parts, the frame weldments of existing vehicles and many tooling devices are still integrally welded, with a relatively large overall size. When the entrance of the cave is too small to pass through, it is necessary to disassemble multiple components including the engine, and then assemble and weld them after entering the cave. Since the engine is relatively heavy, this disassembly and reassembly process consumes a lot of time and manpower, significantly increasing the construction cost. Summary of the Utility Model

[0037] Embodiment 1

[0038] Such as Figure 1 、 Figure 2Shown is a frame structure of an underground vehicle disclosed in this embodiment, which mainly includes a front frame 1 and a rear frame. The rear frame includes a first welded part 2 and a second welded part 3. Specifically, a front leg mounting seat 4 is provided at the first end of the front frame 1 for mounting a front oil cylinder leg. The second end of the front frame 1 is hinged to the first end of the first welded part 2 to form a bogie. A first connecting plate 201 is provided at the second end of the first welded part 2, and a second connecting plate 301 is provided at the first end of the second welded part 3. The first connecting plate 201 and the second connecting plate 301 are detachably connected by a plurality of groups of bolts. At the same time, rear leg mounting seats 5 are welded on both sides of the first connecting plate 201 for mounting rear oil cylinder legs. Among them, both the first connecting plate 201 and the second connecting plate 301 are U-shaped structures to make way for the tooling on the frame structure.

[0039] In this embodiment, by splitting the rear frame into a first welded part 2 and a second welded part 3, the entire frame structure can be split into three parts, and the first welded part 2 and the second welded part 3 are detachably assembled by using the first connecting plate 201 and the second connecting plate 301 in cooperation with a plurality of groups of bolts, which can be quickly disassembled and assembled, making the frame structure have the advantage of fewer disassembly and assembly steps, and can effectively adapt to narrow environments such as underground mines and tunnels. At the same time, the rear leg mounting seats 5 are arranged on both sides of the first connecting plate 201, so that the distance between the connection of the rear legs and the frame welded parts is basically 0, so that the load at the connection of the frame welded parts can be quickly transmitted to the ground, improving the overall service life of the frame structure.

[0040] In the specific implementation process, the second welded part 3 further includes a tail seat 302, a first side plate 303 and a second side plate 304. The overall structures of the first side plate 303 and the second side plate 304 are basically the same and symmetric to each other. The first ends of the first side plate 303 and the second side plate 304 are fixedly connected to the second connecting plate 301 by welding, and the second ends of the first side plate 303 and the second side plate 304 are fixedly connected to the tail seat 302 by welding.

[0041] Further specifically, radiator supports 6 are connected to the inner walls of the first side plate 303 and the second side plate 304 near the tailstock 302, and the radiator supports 6 are connected to the tailstock 302. Engine supports 7 are provided on the inner walls of the first side plate 303 and the second side plate 304 near the second connecting plate 301 for mounting the engine 15. The radiator supports 6 and the engine supports 7 are integrally located at the top position of the second welded part 3. When the radiator 21 and the engine 15 are assembled on the second welded part 3, they only occupy a certain space in the height direction of the second welded part 3, but do not occupy space in the width direction (the width direction of the whole vehicle). Therefore, in the specific application process, even if the radiator 21 and the engine 15 on the second welded part 3 are not disassembled, it can smoothly pass through some narrow mine tunnels or tunnels, which can save the disassembly and assembly of the engine 15 and the radiator 21, greatly reducing the disassembly and assembly cost and installation time, and improving work efficiency.

[0042] Reference Figures 3 to 5 , an oil tank assembly station 8 is provided on the outer wall of the first side plate 303, and a post-treatment component assembly station 9 is provided on the outer wall of the second side plate 304. Among them, the oil tank assembly station 8 is specifically an installation hole provided on the first side plate 303, so that the oil tank 16 can be detachably installed on the first side plate 303 by bolts. The post-treatment component assembly station 9 is also an installation hole provided on the second side plate 304, so that the post-treatment component 17 can be detachably installed on the first side plate 303 by bolts.

[0043] As a preferred embodiment, a first cover 10 is connected to the outer wall of the second side plate 304 by bolts. The first cover 10 is integrally in a hood-like structure, so that the first cover 10 can cover the post-treatment component assembly station 9. At the same time, an air storage tank assembly station 11 is provided at the top of the first cover 10, specifically an installation hole or a support seat provided at the top of the first cover 10. During assembly, first install the post-treatment component 17 on the second side plate 304, and then install the first cover 10 so that the first cover 10 covers the post-treatment component 17 for protection. Finally, install the air storage tank 18 on the top of the first cover 10 by bolts and other fasteners, so that the first cover 10 simultaneously serves the functions of protection and installation support.

[0044] Considering that the heights of the post-processing component 17 and the gas storage tank 18 are relatively low after installation, there is still a certain amount of remaining space on the corresponding side of the frame structure at the second side plate 304. Therefore, in this embodiment, preferably, a second covering member 12 is fixedly connected to the tailstock 302 by bolts to protect the tail of the frame structure. At the same time, an air filter mounting bracket 13 is connected to the side of the second covering member 12 corresponding to the second side plate 304. The air filter mounting bracket 13 is located above the gas storage tank assembly station 11, so that the air filter 19 can be installed above the gas storage tank 18, which can not only facilitate the connection between the air filter 19 and the gas storage tank 18, but also make full use of the remaining space on the side of the frame structure, and at the same time enable the second covering member 12 to also serve the functions of protection and installation support.

[0045] Similarly, after the fuel tank 16 is installed on the first side plate 303, there is also a certain amount of remaining space on the corresponding side of the frame structure at the first side plate 303. Therefore, in this embodiment, preferably, a cable reel assembly station 14 is provided at the end of the tailstock 302 close to the first side plate 303, specifically a hinge hole, so that the cable reel 20 can be hinged to the tailstock 302 and can be rotated to a position above the fuel tank 16, thereby making full use of the remaining space on the side of the frame structure.

[0046] Generally speaking, in this embodiment, a series of installation stations are arranged on the side plates of the second welded part 3 and the tailstock 302, so that the tooling equipment such as the fuel tank 16, the post-processing component 17, the gas storage tank 18, the air filter 19, and the cable reel 20 on the working condition vehicle can all be removable fittings on the second welded part 3. This enables the engine 15 and the radiator frame on the second weld to pass through a smaller hole without being disassembled, eliminating the disassembly and assembly process of the engine 15, greatly saving the disassembly and assembly cost, improving the work efficiency, and at the same time improving the environmental adaptability of the frame structure.
