A kind of two column belt elevators reprinted that derail
Technical field
The present invention relates to mechanical automation transportation art, particularly relate to a kind of two column belt elevators that can realize the automatic derailing switching of ground transport line and aerial conveying line for self-propelled cart system.
Background technology
At present, common elevator is distinguished according to type of drive, has chain elevator and belt elevator two kinds; And distinguish according to structure, there are again four posts and the comparatively common version of two kinds, two post elevators.
Traditional automatic carriage elevator, by the impact of conveying weight, if do not have the restriction of installing space, the general four upright type lifting machines that adopt of heavy duty are comparatively reliable, but four post elevator integral structures are comparatively complicated heavy, make and cost of installation all higher.And two upright type lifting machine compact conformations, can effectively utilize limited hall space.Four post elevators are arranged on the both sides perpendicular to line running body direction, belt arrangement is bilateral formula, by telescopic hold-down arm, workpiece can be departed from delivery track from previous load transfer device to reprint, but two post belt elevators arrange online body side, together must reprint with track, by track and workpiece synchronization lifting, realize the orbital docking conveying between ground transport line and aerial conveying line.This transporting pattern needs on balladeur train, connect C type and hangs pin, and C type hangs the automatic carriage track of pin connecting aluminum alloy.Sliding framework structure is complicated, and orbital docking is poor, and precision is not high, and processing and fabricating cost is high.Reprint if two column belt elevators will realize derailing, must be furnished with the function that telescopic fork realizes similar four post elevator telescopic booms, but telescopic fork price costly, cost of manufacture can significantly improve.
Summary of the invention
The object of the present invention is to provide a kind of two column belt elevators reprinted that derail, with an improved the structure of common two column belt elevators, make it can arrange four belts simultaneously, realize the balladeur train form identical with four column belt elevators thus can realize derailing reprinting, remain the advantage of two post elevator compact overall structure, to solve in prior art at belt elevator Problems existing simultaneously.
For reaching this object, the present invention by the following technical solutions:
A kind of two column belt elevators reprinted that derail, it comprises elevator base, two root posts, elevator upper frame and balladeur train, described column bottom is connected with elevator base, described elevator upper frame is connected to the top of column, described balladeur train can slide up and down and is assemblied on column, wherein, described elevator upper frame is installed driving roller assembly and turnabout roller assembly, described driving roller assembly connects drive motor, article four, drive one end of belt to be connected with balance weight assembly, the other end is walked around driving roller assembly respectively and is connected with two balladeur train ends with turnabout roller assembly.
Especially, track laid by described column, described balladeur train has the guide wheel can embracing track and travelling wheel, balladeur train is held railway limit tightly by guide wheel and is walked on column track.
Especially, described balance weight assembly is hidden in the column that is arranged at and installs driving roller side, and it on, installation travelling wheel is spacing and be elevated on two column madial walls.
Especially, described column is made up of the opposed cloth connection gusset that adds of bending part.
Beneficial effect of the present invention is, compared with prior art the column of the described two column belt elevators reprinted that can derail adds the form that cloth connects gusset substitute conventional rectangular tube or H profile steel with bending part is opposed, increase the width in the non-track installation face of column, enough arrange that four belts are connected with both sides balladeur train respectively.Column is the carrying column of whole elevator, is again the orbit of balladeur train and counterweight, eliminates independently track, and structure is simple, easy to process.Belt is connected with two balladeur trains respectively, realizes the lifting of two ends balladeur train with a balance weight assembly.Not only compact conformation, take up room little, integral module is spirally connected assembled, is easy to in-site installation; The online body both sides of balladeur train are arranged, four point positioning, and the steady derailing that can realize workpiece is reprinted; And equipment runs hourly velocity soon, noise is low, is easy to care and maintenance, is conducive to user's speed production beat, improves production capacity.

Fig. 1 is the front view of two column belt elevators of the derailed reprinting that the specific embodiment of the invention 1 provides;
Fig. 2 is the lateral plan of two column belt elevators of the derailed reprinting that the specific embodiment of the invention 1 provides.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, in the present embodiment, a kind of two column belt elevators reprinted that derail comprise two root posts 2, described column 2 is made up of the opposed cloth connection gusset that adds of bending part, add the width in the non-track installation face of wide column, all be connected with elevator base 1 bottom it, and the top of described column 2 connects elevator upper frame 4, balladeur train 3 can slide up and down and is assemblied on column 2, track 10 laid by described column 2, described balladeur train 3 is installed guide wheel and the travelling wheel that can embrace track 10, it is spacing and walk on the track of column 2 that balladeur train 3 holds track 10 tightly by guide wheel, described elevator upper frame 4 is installed driving roller assembly 5 and turnabout roller assembly 6, described driving roller assembly 5 connects drive motor, article four, drive one end of belt 9 to be connected with balance weight assembly 7, the other end is walked around driving roller assembly 5 respectively and is connected with two balladeur train 3 ends with turnabout roller assembly 6, in the hiding column being arranged at installation driving roller side of described balance weight assembly 7, it is installed travelling wheel spacing and be elevated on two column 2 madial walls.
The above-mentioned two column belt elevators not only compact conformation reprinted that derails, take up room little, integral module is spirally connected assembled, is easy to in-site installation; The online body both sides of balladeur train are arranged, four point positioning, and the steady derailing that can realize workpiece is reprinted; And equipment runs hourly velocity soon, noise is low, is easy to care and maintenance, is conducive to user's speed production beat, improves production capacity.
