下面通过具体的实施例并结合附图对本发明做进一步的详细描述。The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

参见图1和图2,本实施例提供的输送车,转动凸轮轴500时,第一凸轮300和第二凸轮400能够与凸轮轴500同步转动,第一凸轮300转动时,第一凸轮300的回转面能够推动第一摆臂600绕摆臂轴800摆动,以利用第一摆臂600驱动第一轮轴100相对支撑架升降;第二凸轮400转动时,第二凸轮400的回转面能够推动第二摆臂700绕摆臂轴800摆动,以利用第二摆臂700驱动第二轮轴200相对支撑架升降。当转动凸轮轴500,使得第一轮轴100相对支撑架上升时,第二轮轴200维持当前高度或下降;当转动凸轮轴500,使得第二轮轴200相对支撑架下降时,第二轮轴200维持当前高度或上升,从而,通过转动凸轮轴500,便可选择第一轮轴100着地,还是第二轮轴200着地。Referring to FIGS. 1 and 2 , in the transport vehicle provided in this embodiment, when the camshaft 500 is rotated, the first cam 300 and the second cam 400 can rotate synchronously with the camshaft 500 , and when the first cam 300 rotates, the first cam 300 rotates The revolving surface can push the first swing arm 600 to swing around the swing arm shaft 800, so as to use the first swing arm 600 to drive the first axle 100 to move up and down relative to the support frame; when the second cam 400 rotates, the revolving surface of the second cam 400 can push the first axle 100 to move up and down. The second swing arm 700 swings around the swing arm shaft 800 to drive the second axle 200 to move up and down relative to the support frame by the second swing arm 700 . When the camshaft 500 is rotated to make the first axle 100 rise relative to the support frame, the second axle 200 maintains the current height or descends; when the camshaft 500 is rotated to make the second axle 200 descend relative to the support frame, the second axle 200 maintains the current height height or rise, so that by rotating the camshaft 500, it is possible to select whether the first axle 100 or the second axle 200 touches the ground.

当输送车的第一轮轴100上的滚轮着地时,若需要换向,则可转动凸轮轴500,使第一轮轴100相对支撑架上升或使第二轮轴200相对支撑架下降,直到第一轮轴100上的滚轮离地,且第二轮轴200上的滚轮着地为止,如此,输送车的输送方便就会有垂直于第一轮轴100的方向,转换为垂直于第二轮轴200的方向;同样,当输送车的第二轮轴200上的滚轮着地时,若需要换向,则可转动凸轮轴500,使第一轮轴100相对支撑架下降或使第二轮轴200相对支撑架上升,直到第二轮轴200上的滚轮离地,且第一轮轴100上的滚轮着地为止,如此,输送车的输送方便就会有垂直于第二轮轴200的方向,转换为垂直于第一轮轴100的方向。When the roller on the first axle 100 of the conveying vehicle touches the ground, if the direction needs to be reversed, the camshaft 500 can be rotated to make the first axle 100 rise relative to the support frame or make the second axle 200 descend relative to the support frame until the first wheel axle The roller on the 100 lifts off the ground, and the roller on the second axle 200 touches the ground. In this way, the transportation of the conveying vehicle will be in a direction perpendicular to the first axle 100 and converted to a direction perpendicular to the second axle 200; similarly, When the roller on the second axle 200 of the conveying vehicle touches the ground, if the direction needs to be reversed, the camshaft 500 can be rotated to make the first axle 100 descend relative to the support frame or make the second axle 200 rise relative to the support frame until the second axle The roller on the 200 lifts off the ground and the roller on the first axle 100 touches the ground. In this way, the conveying vehicle will have a direction perpendicular to the second axle 200 and be converted to a direction perpendicular to the first axle 100.

因此,本实施例提供的输送车,结构简单,成本较低,而且仅需转动凸轮轴500便可实现换向功能,操作简单,耗时较短,从而,运输货物的效率较高。Therefore, the conveying vehicle provided in this embodiment has a simple structure and low cost, and only needs to rotate the camshaft 500 to realize the reversing function, which is easy to operate and takes less time, so that the efficiency of transporting goods is high.

例如,凸轮轴500在初始位置时,第二轮轴200上的滚轮着地,第一轮轴100上的滚轮离地;凸轮轴500沿特定方向(将该方向定义为正向)从初始位置转动到相对初始位置偏角α的过程中,第一摆臂600和第二摆臂700均维持当前现状,第一轮轴100和第二轮轴200均维持在当前高度;凸轮轴500沿正向从相对初始位置从偏角α转动到偏角β的过程中,第一摆臂600摆动,带动第一轮轴100下降,同时,第二摆臂700维持现状,使得第二轮轴200维持在当前高度;当凸轮轴500转动到相对初始位置偏角β的位置时,第一轮轴100上的滚轮着地,此时,第二轮轴200上的滚轮也处于着地状态;当凸轮轴500沿正向从相对初始位置从偏角β转动到偏角γ的过程中,第一摆臂600和第二摆臂700均维持现状,第一轮轴100和第二轮轴200均维持在当前高度;当凸轮轴500沿正向从相对初始位置偏角γ转动到δ的过程中,第一摆臂600维持现状,第二摆臂700摆动,带动第二轮轴200上升;当凸轮轴500转动到相对初始位置偏角δ的位置时,第二轮轴200上的滚轮离地,此时,第一轮轴100上的滚轮维持着地状态,如此,便实现了输送车的换向。For example, when the camshaft 500 is in the initial position, the roller on the second axle 200 touches the ground, and the roller on the first axle 100 leaves the ground; the camshaft 500 rotates in a specific direction (defined as the positive direction) from the initial position to the opposite During the process of the initial position declination α, the first swing arm 600 and the second swing arm 700 both maintain the current status, the first axle 100 and the second axle 200 are both maintained at the current height; In the process of rotating from the declination angle α to the declination angle β, the first swing arm 600 swings, driving the first axle 100 to descend, and at the same time, the second swing arm 700 maintains the status quo, so that the second axle 200 is maintained at the current height; when the camshaft When the camshaft 500 rotates to a position relative to the initial position of the deflection angle β, the roller on the first axle 100 touches the ground, and at this time, the roller on the second axle 200 is also in the grounding state; During the rotation from the angle β to the declination angle γ, the first swing arm 600 and the second swing arm 700 both maintain the current status, and the first axle 100 and the second axle 200 are both maintained at the current height; When the initial position declination γ rotates to δ, the first swing arm 600 maintains the status quo, and the second swing arm 700 swings, driving the second axle 200 to rise; when the camshaft 500 rotates to a position relative to the initial position declination δ, The rollers on the second axle 200 are off the ground, and at this time, the rollers on the first axle 100 are kept on the ground, so that the reversing of the conveying vehicle is realized.
