A kind of two column belt elevators that derail and reprint
Technical field
The present invention relates to the mechanical automation transportation art, relate in particular to a kind of two column belt elevators that self-propelled cart system can be realized the automatic derailing switching of ground travel line and aerial travel line that are used for.
Background technology
At present, common elevator is distinguished according to type of drive, and two kinds on chain elevator and belt elevator arranged; And distinguish according to structure, four posts and two kinds of comparatively common versions of two post elevators are arranged again.
Traditional automatic carriage elevator is carried the influence of weight, if there is not the restriction of installing space, heavy duty generally adopts four column elevators comparatively reliable, but four post elevator integral structures are comparatively complicated heavy, and making and cost of installation are all than higher.And two column elevator structures are compact, can effectively utilize limited factory building space.Four post elevators are installed in the both sides perpendicular to line running body direction; Belt arrangement is the bilateral formula; Can workpiece be broken away from delivery track from previous load transfer device through the retracted support arm and reprint, but two post belt elevators are arranged online body one side, must be with track together to reprint; With track and workpiece synchronization lifting, realize that the orbital docking between ground travel line and the aerial travel line is carried.This transporting pattern need connect the C type and hang pin on balladeur train, the C type hangs the automatic carriage track that pin connects aluminum alloy.The balladeur train complex structure, orbital docking property is poor, and precision is not high, and the processing and fabricating cost is high.If two column belt elevators will be realized derailing and reprint then must be furnished with the function that telescopic fork is realized similar four post elevator telescopic booms, but the telescopic fork price is comparatively expensive, 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 that derail and reprint; It has improved the structure of common two column belt elevators; Make it can arrange four belts simultaneously; Thereby realize to realize the derailing reprinting, kept the advantage of two post elevator compact overall structure simultaneously, to solve the problem that exists at the belt elevator in the prior art with the identical balladeur train form of four column belt elevators.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of two column belt elevators that derail and reprint; It comprises elevator base, two root posts, elevator upper frame and balladeur train, and said column bottom is connected with the elevator base, and said elevator upper frame is connected in the top of column; Said balladeur train can slide up and down and is assemblied on the column; Wherein, installing drive roller component and changed course roller component on the said elevator upper frame, said driving roller assembly connects drive motor; Article four, an end of driving belt links to each other with balance weight assembly, and the other end is walked around the driving roller assembly respectively and linked to each other with two balladeur train ends with the changed course roller component.
Especially, lay track on the said column, guide wheel and the travelling wheel that can embrace track are arranged on the said balladeur train, it is spacing and on the column track, walk that balladeur train is held track tightly through guide wheel.
Especially, said balance weight assembly is hidden and to be arranged in the column of installing drive roller one side, and the installation travelling wheel is spacing and on two column madial walls, go up and down it on.
Especially, said column is made up of the opposed cloth connection gusset that adds of bending part.
Beneficial effect of the present invention does; The column of two column belt elevators of the compared with prior art said reprinting of derailing substitutes rectangular tube or H shaped steel commonly used with the opposed form that adds cloth connection gusset of bending part; Increased the width of the non-track attachment face of column, arranged that enough four belts are connected with the both sides balladeur train respectively.Column is the carrying column of whole elevator, is again the orbit of balladeur train and counterweight, has saved independently track, and is simple in structure, easy to process.Belt is connected with two balladeur trains respectively, realizes the up-down of two ends balladeur train with a balance weight assembly.Compact conformation not only, it is little to take up room, and the integral moduleization assembly unit that is spirally connected is easy to on-site installation; The online body of balladeur train both sides are arranged, four point locations can realize that the steady derailing of workpiece is reprinted; And speed is fast during equipment operation, and noise is low, is easy to care and maintenance, helps user's speed production beat, improves production capacity.
Description of drawings
Fig. 1 is the front view of two column belt elevators of the derailed reprinting that provides of the specific embodiment of the invention 1;
Fig. 2 is the lateral plan of two column belt elevators of the derailed reprinting that provides of the specific embodiment of the invention 1.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
See also shown in Figure 1ly, in the present embodiment, a kind of two column belt elevators of reprinting that derail comprise two root posts 2; Said column 2 is made up of the opposed cloth connection gusset that adds of bending part, adds the width of the non-track attachment face of wide column, and its bottom all is connected with elevator base 1; And the top of said column 2 connects elevator upper frame 4, and balladeur train 3 can slide up and down and is assemblied on the column 2, lays track 10 on the said column 2; Guide wheel and the travelling wheel that can embrace track 10 is installed on the said balladeur train 3; It is spacing and on the track of column 2, walk that balladeur train 3 is held track 10 tightly through guide wheel, installing drive roller component 5 and changed course roller component 6 on the said elevator upper frame 4, and said driving roller assembly 5 connects drive motor; Article four, an end of driving belt 9 links to each other with balance weight assembly 7; The other end is walked around driving roller assembly 5 respectively and is linked to each other with two balladeur trains, 3 ends with changed course roller component 6, and said balance weight assembly 7 is hidden and is arranged in the column of installing drive roller one side, and installation travelling wheel is spacing and on two columns, 2 madial walls, go up and down on it.
The above-mentioned not only compact conformation of the two column belt elevators reprinted that derails, it is little to take up room, and the integral moduleization assembly unit that is spirally connected is easy to on-site installation; The online body of balladeur train both sides are arranged, four point locations can realize that the steady derailing of workpiece is reprinted; And speed is fast during equipment operation, and noise is low, is easy to care and maintenance, helps user's speed production beat, improves production capacity.
