Abstract
The utility model discloses a step-climbing dolly, which comprises a frame, drive wheels, satellite wheels, and rear wheels. The satellite wheels are mounted on the two sides of the front end of the frame, the rear wheels are mounted on the two sides of the back end of the frame, and the drive wheels are mounted on the two sides of the frame between the satellite wheels and the rear wheels, wherein the drive wheels and the satellite wheels on the same side of the frame are connected through belt transmission. A tensioner connected with the belt is also arranged on the frame. Each satellite wheel consists of a cross-shaped frame and a belt wheel connected on the outer end thereof. The step-climbing dolly can travel on the ground just as a regular vehicle wheel, automatically change the mode of motion when starting to climb steps, and automatically shift to the ground traveling mode after climbing the last step. Therefore, the step-climbing dolly is reasonable in structure, convenient to use and labor-saving.
Description
Technical field
The utility model discloses a kind of dolly of climbing step, belongs to travelling bogie class technical field.
Background technology
The motor-bug of common handling goods can't chin, like this when goods when upstairs carrying, having to wastes time and energy with manually carrying on the building, very heavy goods also quite bothers.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of reasonable in design, easy to use, dolly of climbing step of saving labor.
The utility model is achieved through the following technical solutions:
The utility model comprises vehicle frame, drive wheel, satellite wheel and rear wheel, the satellite wheel is installed in the both sides of vehicle frame front end, rear wheel is installed in the both sides of vehicle frame rear end, drive wheel is installed the both sides of the vehicle frame between satellite wheel and the rear wheel, wherein, the drive wheel of vehicle frame homonymy is connected by strap drive with the satellite wheel.
Also be equipped with and be with the bonded assembly tension wheel on the described vehicle frame.
Described satellite wheel is that cross bar and the belt wheel that is connected the cross bar outer end are formed.
The utility model tension wheel can be under the effect of spring elastic movement up and down, when the device stair climbing, band can not broken because of falling short of synchronously like this.Used band is to be with synchronously, and rear wheel is also formed for cross bar and the roller that is connected the cross bar outer end.During the level land, the front and back cross bar is motionless, and drive wheel band synchronously moves ahead the satellite wheel; When running into step, be with driven satellite wheel to be stuck synchronously and stop to roll, the cross bar of satellite wheel begins to rotate under the driving of band synchronously, transfers the step state of climbing to by the level land rolling condition.This device can be used for the self-propelled vehicle of handling goods, also can be used for motorized wheel chair, and its advantage has: can walk on the ground as usual wheel for motor vehicle on the level land; When step, this device changes mode of motion automatically and begins to climb step; When having climbed last step, be automatically converted to the level walking state again, have rational in infrastructure, easy to use, advantage such as save labor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The scheme drawing of band rotation synchronously when Fig. 2 climbs step for the utility model;
The scheme drawing of band rotation synchronously when Fig. 3 is the utility model level land.
Wherein, 1, vehicle frame, 2, drive wheel, 3, the satellite wheel, 4, rear wheel, 5, tension wheel, 6, band.
The specific embodiment
Embodiment: structure as shown in Figure 1, the utility model comprises vehicle frame 1, drive wheel 2, satellite wheel 3 and rear wheel 4, satellite wheel 3 is installed in the both sides of vehicle frame front end, rear wheel 4 is installed in the both sides of vehicle frame rear end, drive wheel 2 is installed the both sides of the vehicle frame 1 between satellite wheel and the rear wheel, wherein, the drive wheel of vehicle frame 1 homonymy and satellite wheel is by being with 6 to be in transmission connection.Also be equipped with and be with bonded assembly tension wheel 5 on the vehicle frame.Satellite wheel 3 is that cross bar and the belt wheel that is connected the cross bar outer end are formed.
Show that as Fig. 3 during the level land, the front and back cross bar is motionless, drive wheel 2 drives to be with synchronously the satellite wheel is moved ahead; Show as Fig. 2, when running into step, be with driven satellite wheel to be stuck synchronously and stop to roll that the cross bar of satellite wheel 3 begins to rotate under the driving of band synchronously, thus climb steps easily.When having climbed last step, be automatically converted to the level walking state again.
