[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0023] A typical embodiment of the present utility model is as Figure 1As shown in the figure, a loading locomotive frame structure includes a front frame 1 and a rear frame 2. The front frame 1 and the rear frame 2 are connected by a hinge structure 3. A front drive axle is arranged at the bottom of the front frame 1, and a rear drive axle is arranged at the bottom of the rear frame 2. The distance from the front drive axle to the hinge structure 3 is equal to the distance from the rear drive axle to the hinge structure 3. This structure can reduce the turning radius, thus meeting the operation requirements within a small space range.
[0024] As Figure 2 shown in the figure, the rear frame 2 includes side plates 21 and a connecting plate 22. There are two side plates 21, and the two side plates 21 are arranged in parallel. A plurality of cross beams 23 are connected between the two side plates 21 to ensure the strength of the overall structure. The connecting plate 22 is arranged on the front side of the two side plates 21 and is fixedly connected to the two side plates 21. The connecting plate 22 is rotatably connected to the front frame 1 through the hinge structure 3.
[0025] A cab 4 is arranged above the rear frame 2. A gearbox 5 and an engine 6 are arranged at the bottom of the cab 4. Both the gearbox 5 and the engine 6 are located between the two side plates 21, and the engine 6 is located behind the gearbox 5. A counterweight 7 is fixedly connected to the rear sides of the two side plates 21.
[0026] By arranging the gearbox 5 and the engine 6 at the bottom of the cab 4 and fixing the counterweight 7 to the rear sides of the two side plates 21, the center of gravity height is reduced and the center of gravity is shifted backward, improving the stability of the loader during driving and loading.
[0027] As Figure 3 shown in the figure, the hinge structure 3 includes an upper hinge mechanism and a lower hinge mechanism. The upper hinge mechanism is located directly above the lower hinge mechanism, and the upper hinge mechanism and the lower hinge mechanism are arranged side by side. The upper hinge mechanism includes a first hinge seat 31, a second hinge seat 32, and a hinge plate 33. The first hinge seat 31 is fixed to the upper part of one end of the front frame 1 close to the rear frame 2. The second hinge seat 32 is fixed to the upper part of the connecting plate 22. Hinge holes are provided at both ends of the hinge plate 33 and are rotatably connected to the first hinge seat 31 and the second hinge seat 32 through a rotating shaft.
[0028] The lower hinge mechanism includes a third hinge seat 34 and a fourth hinge seat 35. The third hinge seat 34 is fixed to the lower part of one end of the front frame 1 close to the rear frame 2, below the first hinge seat 31. The fourth hinge seat 35 is fixed to the lower part of the connecting plate 22, below the second hinge seat 32. Hinge holes are provided on both the third hinge seat 34 and the fourth hinge seat 35, so as to realize the rotational connection between the third hinge seat 34 and the fourth hinge seat 35 through a rotating shaft.
[0029] By setting the first hinge mechanism and the second hinge mechanism, the load-bearing capacity and reliability of the hinge structure can be improved.
[0030] The front side of the front frame 1 is connected to the bucket 8 and the loader working device 9 through a bushing structure, so that the relative movement between the bucket 8 and the loader working device 9 is realized by using the front frame 1.
[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
