Utility model content

The utility model is intended to address the above problem, a kind of doffer dolly is provided, it has overcome dolly easily stuck problem and problem of using existing doffer with dolly, the flatness of guide rail to be had relatively high expectations in running for existing doffer, and its technical scheme adopting is as follows:

A doffer dolly, is characterized in that, comprising:

Car body,

Driving wheel, it is connected with motor by rotating shaft and the power train that is built in car body, and the circumferential surface of described driving wheel fits on the upper surface of upper rail;

Directive wheel on first, it is rotationally connected with the connector being fixed on car body, and the circumferential surface of directive wheel fits on the right surface of upper rail on described first;

Lower directive wheel, itself and car body are rotationally connected and its circumferential surface fits on the left surface of lower guideway, and described lower directive wheel is at least two;

And with first on directive wheel, lower directive wheel acting in conjunction make car body be equilibrated on upper rail and lower guideway and the driven pulley assembly that can slide along upper rail.

Optionally, described driven pulley assembly is mainly comprised of directive wheel, connector and driven pulley on second, described connector is fixed on car body, on described second, directive wheel and connector are rotationally connected, on described second, the circumferential surface of directive wheel fits on the right surface of upper rail, and directive wheel is at least one on described second.

Optionally, described driven pulley assembly is mainly comprised of driven pulley and baffle plate, and described baffle plate is connected in the right side of driven pulley.

On technique scheme basis, described driving wheel is made by Polyurethane or rubber.

On technique scheme basis, on directive wheel, second, directive wheel and lower directive wheel are bearing on described first.

On technique scheme basis, described driven pulley is hard wheel, and hard wheel specifically refers to that the face of rolling is the wheel of stiff dough, as the wheel of being made by materials such as iron or steel.

The utlity model has following advantage: simple in structure, overcome dolly easily stuck problem and problem of using existing doffer with dolly, the flatness of guide rail to be had relatively high expectations in running for existing doffer, move smooth-going.

The specific embodiment

Embodiment 1

Here it should be noted that, in literary composition, upper and lower, the left and right of the noun of locality is all that to take the view shown in Fig. 4 be benchmark definition, should be appreciated that the use of the described noun of locality should not limit the protection domain that the application asks.Hereinafter described the upper and lower noun of locality, all as benchmark, repeats no more.

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As shown in Figure 3, a kind of doffer dolly, is characterized in that, comprising:

Car body 1,

Driving wheel 5, it is connected with motor by rotating shaft and the power train that is built in car body 1, and the circumferential surface of described driving wheel 5 fits on the upper surface of upper rail 2;

On first, directive wheel 6, and it is rotationally connected with the connector 4 being fixed on car body 1, and the circumferential surface of directive wheel 6 fits on the right surface of upper rail 2 on described first;

Lower directive wheel 10, itself and car body 1 are rotationally connected and its circumferential surface fits on the left surface of lower guideway 3, and described lower directive wheel 10 is two;

And with first on directive wheel 6,10 actings in conjunction of lower directive wheel make car body 1 be equilibrated on upper rail 2 and lower guideway 3 and the driven pulley assembly that can slide along upper rail 2.

Described driven pulley assembly is mainly comprised of driven pulley 7 and baffle plate 9, and described baffle plate 9 is connected in the right side of driven pulley 7.

Preferably, described driving wheel 5 is made by Polyurethane or rubber.

Preferably, described driven pulley 7 is hard wheel, and hard wheel specifically refers to that the face of rolling is the wheel of stiff dough, as the wheel of being made by materials such as iron or steel.

Embodiment 2

As shown in Figure 4 and Figure 5, a kind of doffer dolly, is characterized in that, comprising:
