DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0021] As shown in Figures 1-4 The present embodiment provides a truck walking aid wheel, which comprises a walking aid mechanism 1, and the walking aid mechanism 1 comprises a support frame 2 and a walking roller 4. The lower surface of the support frame 2 is provided with reinforcing ribs 8. The support frame 2 and the reinforcing ribs 8 are both Q235 material components. The reinforcing ribs 8 are fixedly connected with the support frame 2 by welding. A roller shaft 7 is connected between the walking roller 4 and the support frame 2. The walking roller 4 is rotatably connected with the support frame 2 through the roller shaft 7. A wheel groove 6 is formed in the upper portion of the support frame 2. Limiting mechanisms 5 are arranged on the upper surface of the support frame 2 at both sides of the wheel groove 6. Each limiting mechanism 5 comprises an upper limiting plate 501 and a lower limiting plate 502. Both the upper limiting plate 501 and the lower limiting plate 502 are L-shaped structural components. A shaft 504 is arranged in one end of each of the upper limiting plate 501 and the lower limiting plate 502. A limiting sliding block 505 is arranged at the lower end of the shaft 504. The upper limiting plate 501 and the lower limiting plate 502 are rotatably connected with the limiting sliding block 505 through the shaft 504. An installation groove 9 is formed in the inner portion of the support frame 2 at the outer side of the limiting sliding block 505. The limiting sliding block 505 is limitingly and slidably connected with the installation groove 9.

[0022] As shown in Figures 2-3 In the present embodiment, a fixed clamping tooth 901 is arranged in the inner portion of the installation groove 9. A taking-out notch 902 is formed in one end of the installation groove 9. An elastic clamping tooth 506 is arranged at the outer side of the limiting sliding block 505. The limiting sliding block 505 is clamped with the fixed clamping tooth 901 through the elastic clamping tooth 506. A positioning insertion hole 503 is formed in the inner portion of one end of the upper limiting plate 501 and the lower limiting plate 502, which is away from the shaft 504. A handle 3 is arranged at both ends of the walking aid mechanism 1. The handle 3 is fixedly connected with the support frame 2.

[0023] The working principle of the utility model is: when vehicle breakdown is encountered, the rear wheel end of the vehicle is lifted by the lifting mechanism, the whole walking aid mechanism 1 is placed on the tire position, the tire is correspondingly placed on the position of the wheel groove 6 opened on the support frame 2, after the whole support frame 2 is adjusted to be below the tire position, the two limiting mechanisms 5 above the support frame 2 are opened, the installation positions of the upper limiting plate 501 and the lower limiting plate 502 inside the two limiting mechanisms 5 are oppositely arranged, therefore the upper limiting plate 501 inside one limiting mechanism 5 will correspond to the lower limiting plate 502 inside the other limiting mechanism 5, the limiting pin is inserted into the inside of the positioning hole 503, therefore the two groups of upper limiting plate 501 and lower limiting plate 502 after butt joint will correspond to the two side positions of the tire respectively, the limiting sliding block 505 is pushed in the inside of the installation slot 9 towards the direction of the taking-out gap 902, therefore the elastic clamping tooth 506 will be unidirectionally limited with the fixed clamping tooth 901, the distance between the upper limiting plate 501 and the lower limiting plate 502 to the side position can be adjusted, therefore the whole walking aid mechanism 1 can be prevented from being separated from the side position of the tire in use, after the whole walking aid mechanism 1 is installed, the lifting of the vehicle is disconnected, the tire of the vehicle will be pressed above the support frame 2, when the vehicle is towed, the walking roller 4 inside the support frame 2 can be assisted to rotate to temporarily provide the rolling of the vehicle.
