Technical field
The invention belongs to mechanical manufacturing field, relate to a kind of electric threaded shaft bay-lift, particularly relate to a kind of electric threaded shaft bay-lift with vertically-guided and Stroke Control.
Background technology
Bay-lift is the elevator machinery of a kind of vertical shipper or material resources, is also the equipment carrying out vertical transport in the logistics system such as factory, automated warehouse, and as the connecting device of differing heights travel line.
In the production enterprise such as automobile, trac., according to processing, the assembly technology requirement of part, the travel line adopted adopts upper and lower double-layer structure form usually, wherein, upper strata is mainly used in the conveying of consigning utensil (as pallet, supporting plate, consignment trolley) and upper material (as part, parts, assembly) thereof, lower floor is mainly used in consigning the sky of utensil and returns and send, and a kind of self-raising platform is all configured with in two terminations of travel line, as the connecting device of differing heights (upper strata and lower floor) travel line, with meet two-layer up and down between material transfer demand.
With regard to the self-raising platform of its above-mentioned double-deck travel line two ends configuration, mostly select following two types at present:
1, the driving self-raising platform of hydraulic ram.As, " electric lifting platform " (application number: the utility model patent of 201,220 35696 7.X, Authorization Notice No.: CN202717550U).Such lifting table is characterised in that: chassis is provided with two " X " type fork arms side by side, propelling rod is connected with between two fork arms, two fork arms are provided with some hydraulic rams that can promote fork arm oscilaltion, namely utilize hydraulic efficiency pressure system to provide enough power for lifting process, realize the lifting of (fork arm formula) lifting table.
2, the driving self-raising platform of electric threaded shaft.As, " a kind of electric lifting platform " (application number: the patent of invention of 201210164063.1, Authorization Notice No.: CN202609865U).Such lifting table is characterised in that: screw mechanism is made up of motor, drop-gear box, leading screw and slide block, and slide block screws on leading screw, in addition, the upper underarm of two " scissor arms " is side by side provided with and takes turns corresponding arc-shaped guide rail with drawing high; When leading screw is driven by motor through drop-gear box, pull skid, and the slip of slide block on leading screw can be changed into the at the uniform velocity lifting of bench board, namely can regulate the folding angle of " scissor arm " under the control drawing high wheel, then realize the lifting of (scissor arm) lifting table.
The bay-lift of above-mentioned two types, state processing thereon, the application aspect of assembling travel line, all can there be its some positive beneficial effects, some material transfers between upper and lower two layer heights of travel line can be met, but the application scenario of some particular requirements is had at it, but be also difficult to meet application, as, delivery tracks (as adopted V-way or circular guideway) are configured for some and needs to implement for the travel line of accurate conveying, smooth and easy for guaranteeing the material transfer at travel line two ends, often the docking location of bay-lift after lifting to two ends configuration is needed, the requirement of some particularities is proposed, specifically, often following 2 requirements are had:
1, require that its bay-lift has good straight line elevating function, namely the rectilinearity of vertical lift should be accurately and reliably, and duplicability will be got well, can not be suddenly left, suddenly right, the fashion time difference, to guarantee that accurate after lifting of the delivery track configured and the delivery track that travel line configures is docked thereon, avoid occurring lateral excursion inconsistent phenomenon namely have comparatively strict precise docked position requirement in the horizontal direction.
2, require that its bay-lift has good lifting travel and controls, namely the height of vertical lift should be accurately and reliably, and duplicability will be got well, can not be fluctuated, the fashion time difference, the same, with guarantee the delivery track of the two its upper configuration be elevated after accurate docking, avoid occurring that height offsets inconsistent phenomenon, namely have comparatively strict precise docked position requirement in vertical direction equally, then promote the actual transhipment effect of material between the upper and lower two-layer termination of travel line.
