Problems solved by technology

[0005] However, one side of the walking device is only driven by one driving wheel assembly, which is likely to cause insufficient power, and when one side of the track is damaged, the running device cannot move at all.

Embodiment 1

[0064] Embodiment 1, in order to solve the technical problem of increasing the force-bearing area of ​​the chassis of the traveling device to improve its stability, as figure 1 As shown, the following technical solutions are provided:

[0065] The first truss A1 can move horizontally on both sides of the running frame A.

[0066] Specifically, the first truss A1 can move horizontally on both sides of the walking frame A, that is, the distance between the first truss A1 and the second truss A2 can be controlled, that is, when the distance between the first truss A1 and the second truss A2 is enlarged, When the distance between the first truss A1 and the second truss A2 is reduced, the fire truck can run stably in the woodland in order to increase the force-bearing area of ​​the vehicle body. driving on the road;

[0067] By being able to move the first truss A1 in the horizontal direction relative to the second truss A2, the force bearing area of ​​the fire truck can be incre...

Embodiment 2

[0073] Embodiment 2, in order to solve the technical problem of increasing the stress-bearing area of ​​the chassis of the traveling device to improve its stability, such as Figure 9 As shown, the following technical solutions are provided:

[0074] The second truss A2 can move horizontally on both sides of the running frame A.

[0075] Specifically, the second truss A2 can move horizontally on both sides of the walking frame A, that is, the distance between the first truss A1 and the second truss A2 can be controlled, that is, when the distance between the first truss A1 and the second truss A2 is enlarged, When the distance between the first truss A1 and the second truss A2 is reduced, the fire truck can run stably in the woodland in order to increase the force-bearing area of ​​the vehicle body. driving on the road;

[0076] By being able to move the second truss A2 in the horizontal direction relative to the first truss A1, the stress-bearing area of ​​the fire truck ca...

Abstract

The present invention relates to the technical field of vehicle walking, in particular to an anti-overturning walking device for a woodland fire truck, including a walking frame, a driving pulley, a tensioning pulley, an elastic suspension, a load-bearing pulley, a crawler belt and Drive assembly; the first truss and the second truss are arranged on the opposite side of the walking frame body; the driving pulley and the tension pulley are arranged on the first truss and the second truss; the elastic suspension is arranged on the first truss and the second truss The bottom end, the bottom end of the driving pulley includes a plurality of elastic rollers, and the load-bearing pulley rotates on the elastic rollers; the crawler is ring-shaped and sleeved on the driving pulley, tension pulley and load-bearing pulley; the drive assembly is set On the walking frame body and its output end is connected with a single driving pulley. The present invention uses the first truss and the second truss to make four independently rotating crawler belts on both sides of the walking frame body, thereby improving the mobility and at the same time passing The elastic suspension ensures that the fire body is subjected to less vibration force due to ground obstacles, thereby effectively preventing the body from tipping over.

Description

technical field [0001] The invention relates to the technical field of vehicle walking, in particular to an anti-overturning walking device for a woodland fire truck. Background technique [0002] Fires can seriously threaten people's lives, and forest fires are even more destructive catastrophes. However, due to the overgrown shrubs and undulating terrain in the forest, it is difficult for existing various fire-fighting vehicles to travel therein, and they often cannot reach the fire-extinguishing place in time, and effective fire-extinguishing measures are taken to control the fire. Therefore, a crawler fire truck has appeared; [0003] Based on the current structural analysis of tracked vehicles, it can be seen that there are large dynamic loads and power losses between the main components of the running gear, which greatly limits the maneuverability of the vehicle. Through the study of the performance of the tracked vehicle running gear affected by layout space, weight...
