[0018] Embodiment
[0019] As Figures 1-3As shown, in this embodiment, a mining flatbed truck is mainly disclosed, including a frame 1, a traveling mechanism 2 is arranged below the frame 1, the traveling mechanism 2 includes a first wheel group 21 for rolling on the ground, a second wheel group 22 for rolling on the track and a hydraulic device 23, the first wheel group 21 is connected to the second wheel group 22 through a connecting frame 20, the connecting frame 20 is swingably connected to the lower end of the frame 1, one end of the hydraulic device 23 is fixed to the lower end of the frame 1, and the other end of the hydraulic device 23 is hinged to the first wheel group 21 or the second wheel group 22, or , the other ends of the different hydraulic devices 23 are respectively hinged with the first wheel group 21 and the second wheel group 22; specifically, the frame 1 is a welded box structure with an opening at the bottom, and most of the walking mechanism 2 is covered in the box. The first wheel group 21 and the second wheel group 22 are connected to the two ends of the same connecting frame 20, and there is no interference between the first wheel group 21 and the second wheel group 22. The first wheel group 21, the connecting frame 20 and the second wheel group 22 form a lever-like structure. A support 13 for swinging the connecting frame 20 is welded at the lower end of the frame 1; hydraulic The device 23 acts on at least one of the first wheel group 21 and the second wheel group 22, and is used to change the wheel group for switching walking. If two different hydraulic devices 23 act on the first wheel group 21 and the second wheel group 22 respectively, the two different hydraulic devices 23 work together, that is, one hydraulic device 23 is lifted, and the other hydraulic device 23 is lowered. When the flatbed truck needs to be transported to the bottom of the tunnel through the track in the inclined tunnel, the hydraulic device 23 lifts the first wheel group 21, that is, lowers the second wheel group 22, so that the second wheel group 22 is placed on the track, and slides smoothly to the smooth surface at the bottom of the tunnel through the traction rope, the second wheel group 22 is lifted by the hydraulic device 23, that is, lowers the first wheel group 21, so that the first wheel group 21 contacts the ground for mobile transportation, thereby realizing quick switching of the flatbed truck in different working environments and improving the flexibility and adaptability of the flatbed truck. It should be noted that the walking mechanism 2 can be used in conjunction with auxiliary wheels shared by the ground and the track, and the first wheel group 21 can be combined with existing technologies, such as by adding a universal joint to achieve directional movement.
[0020] Furthermore, in a specific implementation, the first wheel group 21 provided in the embodiment of the utility model is staggered outwardly relative to the second wheel group 22 on a horizontal plane. According to actual working conditions, the first wheel group 21 can be placed on the ground while the second wheel group 22 is placed on the track, thereby effectively dispersing the center of gravity of the vehicle body, reducing the risk of rollover, and improving the stability of the flatbed truck.
[0021] Furthermore, in a specific implementation, a limit block 11 is provided on the frame 1 provided in the embodiment of the utility model for abutting and limiting the lifting of the first wheel group 21 or the second wheel group 22; it effectively prevents the first wheel group 21 or the second wheel group 22 from being lifted too high, avoids possible damage and accidents, and at the same time reduces the load on the hydraulic device 23 to a certain extent, thereby enhancing the reliability of the entire device.
[0022] Furthermore, in specific implementation, multiple sets of traveling mechanisms 2 are provided at the lower end of the above-mentioned frame 1 provided in the embodiment of the present invention; preferably, the multiple sets of traveling mechanisms 2 are symmetrically arranged on the plane of the frame 1, and the first wheel set 21 is arranged at a position close to the outer side of the frame 1, and the second wheel set 22 is arranged at a position close to the inner side of the frame 1, ensuring uniform load distribution during the use of the vehicle and reducing the possibility of the flatbed truck tipping over.
[0023] Furthermore, in specific implementation, a connection seat 12 for connecting a towing rope is provided on the side of the above-mentioned frame 1 provided in the embodiment of the present invention. Specifically, the connection seat 12 is arranged on the front and rear sides in the traveling direction of the flatbed truck.
[0024] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
