Automatic track exchanging trolley

Abstract

The invention discloses an automatic track exchanging trolley. The automatic track exchanging trolley comprises a trolley frame, tracks, traveling wheels and a driving device, wherein the tracks comprise main tracks, auxiliary tracks, movable auxiliary tracks and secondary tracks; the auxiliary tracks are positioned on the inner sides of the two main tracks and arranged in parallel with the main tracks; the secondary tracks are perpendicular to the two main rails; the movable auxiliary tracks are perpendicularly arranged on the two auxiliary tracks; the traveling wheels comprise main rail rollers and secondary track rollers, which are arranged to match the main tracks and the secondary tracks respectively, and driven by a main rail roller driving component and a secondary track roller driving component respectively; the upper part of the trolley frame is further provided with a lifting tool and a lifting drive which is connected with the lifting tool; the lower part of the lifting tool is further provided with a lever; one end of the lever is connected with the trolley frame, while the other end is in pin joint with a fixed piece on the lower part of the lifting tool; and the lever is connected with the secondary track roller at a pivot of the lever by a pin. The automatic track exchanging trolley has the advantages of highly realizing automation, improving working efficiency along with simple structure, low manufacturing cost and extremely easy operation.

Description

technical field [0001] The invention relates to a trolley that can run along a track, in particular to a trolley that can automatically change tracks, and belongs to the technical field of transportation devices. Background technique [0002] Rail Guide Vehicle (Rail Guide Vehicle) is a means of transportation that walks along rails. It can be used for handling and transportation. It has the characteristics of relatively fast acceleration and moving speed. It is suitable for transporting heavy workpieces. Because the guide rails are fixed, it runs smoothly and stops. The location is relatively accurate, the control system is simple, reliable, low manufacturing cost, and easy to popularize and apply. However, we know that the traveling route of the trolley sometimes needs to be changed. It is impossible to have only one track operation mode. According to actual needs, there are The trolleys need to run in different directions, which brings about the problem that the trolleys ...

[0002] Rail Guide Vehicle (Rail Guide Vehicle) is a means of transportation that walks along rails. It can be used for handling and transportation. It has the characteristics of relatively fast acceleration and moving speed. It is suitable for transporting heavy workpieces. Because the guide rails are fixed, it runs smoothly and stops. The location is relatively accurate, the control system is simple, reliable, low manufacturing cost, and easy to popularize and apply. However, we know that the traveling route of the trolley sometimes needs to be changed. It is impossible to have only one track operation mode. According to actual needs, there are The trolleys need to run in different directions, which brings about the problem that the trolleys need to change between the tracks in different directions. Currently, in the market, the trolleys usually use the way of changing tracks by trains. That is to say, the way of switching rails is used to change rails. In this way, the angle of rail switching is very small. If the angle of switching is relatively large, it is necessary to set up a lot of switches on the ground, and the route to be operated to reach the destination is relatively large. It is long and complicated, takes up space, and has a lot of consumables. In addition, at present, there are also two-car ways to change the track, that is, the auxiliary car sits on the main car, the main car is equipped with tracks, and the auxiliary car track There is a big gap with the track of the main car. When the track is changed, the main car stays on the track of the main car, and the auxiliary car moves from the main car to the auxiliary track. This method requires digging holes on the ground, resulting in the partition of the factory building and increasing cost of production
