Abstract

The utility model provides a rail transportation trolley which comprises a first trolley part (1) and a second trolley part (2). The first trolley part (1) and the second trolley part (2) are respectively provided with a pair of wheels which are distributed on the two sides. The first trolley part (1) and the second trolley part (2) are connected in a rotatable mode through an articulated mechanism. According to the rail transportation trolley, the first trolley part (1) and the second trolley part (2) are connected in the rotatable mode through the articulated mechanism, the first trolley part (1) and the second trolley part (2) twist relative to each other so that the four wheels of the whole trolley can make contact with the rails all the time when the rail transportation trolley runs on two uneven rails or runs into unexpected sundries on the rails, and therefore the rail transportation trolley is prevented from getting off the rails.

Description

A kind of rail guided transport trolley

Technical field

The utility model relates to material handling machinery technical field, especially relates to a kind of rail guided transport trolley.

Background technology

Under the environment such as workshop, often have the conveying of material and product, rail guided transport trolley is that frequency of utilization is higher, use more a kind of load transfer device.Rail guided transport trolley is generally at least equipped with four wheels, and four wheels lay respectively at both sides, needs two tracks are installed, and installing and using in process, two tracks of rail guided transport trolley require to install smooth, and accuracy requirement is higher.But in practice process, affected by the factor such as technology and cost, the installation planeness of two tracks may out of reach requirement, in operational process, also can be subject to the factor impacts such as the foreign material that accidentally exist on land subsidence, track wearing and tearing, track.As shown in Figure 1, in prior art, in the time that overall four-wheel transport trolley operates on uneven track, wherein just take turns and can not contact track, very easily cause dolly to be overstepped the limit, dolly can increase labour intensity after overstepping the limit, reduce production efficiency, and the loss that likely brings goods.

Utility model content

The problem existing in order to solve prior art, the utility model provides a kind of rail guided transport trolley, has and operates steadily, and is difficult for derailed feature.

In order to solve the problems of the technologies described above, the rail guided transport trolley that the utility model provides, comprise dolly Part I, dolly Part II, described dolly Part I and Part II respectively have the pair of wheels that is distributed in both sides, and described dolly Part I is connected by linkwork rotationally with Part II.

As one of preferred version: the rail guided transport trolley that the utility model provides, described linkwork comprises the first crossbeam that is positioned at dolly Part I junction and the second cross beam that is positioned at Part II junction; Be positioned at the coaxial through-hole of the hinged place of described first crossbeam and second cross beam; Be positioned at the plain bearing of described through hole; Pass the hinge of the endoporus of described plain bearing; Be positioned at the first surface bearing and second surface bearing in outside, described plain bearing two ends; Be positioned at the first jam nut and the second jam nut that the outside of described the first surface bearing and the second surface bearing is threaded with described hinge.

On the basis of above-mentioned preferred version, further improvement of the utility model scheme: the rail guided transport trolley that the utility model provides, described first crossbeam has the bottom groove concordant with described plain bearing end face with second cross beam, the diameter of described groove is greater than the external diameter of described plain bearing, and described the first surface bearing and the second surface bearing are arranged at respectively in the groove of first crossbeam and second cross beam.

The beneficial effects of the utility model are: the rail guided transport trolley that the utility model provides, dolly Part I is connected by linkwork rotationally with Part II, in the time travelling at two tracks of injustice or run into the foreign material that accidentally exist in orbit, dolly Part I and Part II are under the effect of gravity, produce and reverse each other, make four wheels of whole dolly contact all the time track, thereby avoid the derailed phenomenon of transport trolley.

In preferred version, linkwork arranges plain bearing and surface bearing, and the friction force can reduce dolly Part I and Part II and mutually rotate time has further improved the adaptive capacity of rail guided transport trolley.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the structure of prior art rail guided transport trolley and operates in the schematic diagram on uneven track;

Fig. 2 is the structural representation of embodiment rail guided transport trolley;

Fig. 3 is that the A-A of Fig. 2 is to structural representation;

Fig. 4 is that embodiment rail guided transport trolley operates in the schematic diagram on uneven track.

The specific embodiment

Rail guided transport trolley as shown in Figure 2 and Figure 3, comprise dolly Part I 1, dolly Part II 2, described dolly Part I 1 and Part II 2 respectively have the pair of wheels that lays respectively at both sides, the junction of dolly Part I 1 has first crossbeam, and the junction of Part II 2 has second cross beam, the hinged place of described first crossbeam and second cross beam has coaxial through hole, plain bearing 7 is positioned at described through hole, hinge 6 is through the endoporus of described plain bearing 7, described first crossbeam has the bottom groove concordant with described plain bearing 7 end faces with second cross beam, the diameter of described groove is greater than the external diameter of described plain bearing 7, the first surface bearing 8 and the second surface bearing 5 are arranged at respectively in the groove of first crossbeam and second cross beam, and be positioned at the outside at described plain bearing 7 two ends, the first jam nut 3 is positioned at the outside of described the first surface bearing 8 and is threaded with described hinge 6, the second jam nut 4 is positioned at the outside of described the second surface bearing 5 and is threaded with described hinge 6.As shown in Figure 4, dolly Part I 1 is connected by linkwork rotationally with Part II 2, in the time travelling at two tracks of injustice or run into the foreign material that accidentally exist in orbit, dolly Part I 1 and Part II 2 are under the effect of gravity, produce and reverse each other, make four wheels of whole dolly contact all the time track, thereby avoid derailed phenomenon.

In other embodiments, the replaceable one-tenth of linkwork other can make dolly Part I 1 and Part II 2 under the effect of gravity, produce each other the mechanism of reversing, as hinge etc., also can realize design of the present utility model, solve identical technical matters, and there is identical or close technique effect.

Obviously, the utility model is not limited to above preferred implementation, also can be in the spirit of the utility model claim and specification sheets restriction, carry out conversion and the improvement of various ways, can solve same technical matters, and obtain the technique effect of expection, therefore do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit limiting in claim, also belong to protection domain of the present utility model.
