For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0020] See also Figures 1 to 11 In an embodiment of the present invention, a walking mechanism of a mining loader includes a chassis 1, two front wheels 6 and two rear wheels 9. Two first mounting seats 5 and two second mounting seats 8 are arranged below the chassis 1. A first hydraulic motor 7 is installed at one end of the first mounting seat 5. The first hydraulic motor 7 is used to drive the front wheels 6 to rotate. A second hydraulic motor 10 is installed at one end of the second mounting seat 8. The second hydraulic motor 10 is used to drive the rear wheels 9 to rotate. The top ends of the two second mounting seats 8 are fixedly connected with a connecting frame 11. Two cross bars 13 are fixedly connected to the outer wall of the chassis 1. The top end of the connecting frame 11 is rotatably connected with a mounting frame 12. The mounting frame 12 is installed on the chassis 1 through the mounting unit 2. The first mounting seat 5 is installed on the chassis 1 through the connecting unit 3.

[0021] In this embodiment, the chassis 1 is driven by four independent tires, and the hydraulic motors are directly connected to the tires. Turning is achieved by the asynchronous rotation of the left and right hydraulic motors.

[0022] Please refer to Figures 1 to 4The mounting unit 2 includes a rotating disk 201, which is rotatably connected to the top of the mounting frame 12, and a first bevel gear 202 is fixedly connected to the bottom end of the rotating disk 201. The interior of the mounting frame 12 is symmetrically slidably connected to a fixed block 205 extending to the outer wall of the mounting frame 12, and the interior of the mounting frame 12 is rotatably connected to a first threaded rod 204 extending to the interior of the fixed block 205, and the outer wall of the first threaded rod 204 is fixedly connected to a second bevel gear 203. The first bevel gear 202 is in contact with the second bevel gear 203. A fixing groove 206 is provided between the two cross bars 13, and the inner wall of the base frame 1 is located on one side of the cross bar 13 and is rotatably connected to a first support frame 207. A groove 208 is provided on the outer wall of the first support frame 207. A slider 209 extending from the cross bar 13 is slidably connected to the interior of the cross bar 13, and a first spring 210 is connected between the slider 209 and the cross bar 13. A positioning rod 211 is fixedly connected to the top of the slider 209.

[0023] In this embodiment: when the rear wheel 9 is replaced, the first support frame 207 is rotated to a vertical state. At this time, the bottom end of the first support frame 207 is in contact with the ground for support. At the same time, the first support frame 207 rotates to drive the groove 208 to contact the slider 209. The slider 209 is displaced into the groove 208 by the elastic force of the first spring 210. The displacement of the slider 209 drives the positioning rod 211 to be displaced and separated from the rotating disk 201. At this time, the rotating disk 201 can be rotated, and the rotation of the rotating disk 201 drives the first bevel gear 202 to rotate. The rotation of the first bevel gear 202 drives the second bevel gear 203 to rotate. The rotation of the second bevel gear 203 drives the first threaded rod 204 to rotate. The rotation of the first threaded rod 204 drives the fixing block 205 to displace.

Then, the first support frame 207 is rotated to reset. When the first support frame 207 is rotated and reset, the slider 209 moves out of the groove 208. The displacement of the slider 209 squeezes the first spring 210. The displacement of the slider 209 drives the positioning rod 211 to move and engage with the rotating disk 201, thereby reinforcing the mounting frame 12 to prevent the mounting frame 12 from loosening, which is convenient for replacing the rear wheel 9. During replacement, the first support frame 207 is used for support, and before the first support frame 207 is used for support, the mounting frame 12 is prevented from loosening.
