Description

Large bearing capacity scissor-type lifting platform

Technical field

The utility model relates to elevator field, more precisely a kind of scissor-type lifting platform.

Background technology

Because most of producer or individual are in order to improve the degree of utilization in place, more have selected tier building, also needing a kind of device to come expediently to descend cargo lifting thus.The development of current lifting mechanism is being in a peak state, scissor-type lifting platform leans on the expansion of scissor bearing support and folded the lifting of upper mounting plate, thus reaching the object of lifting goods or aloft work, its power is promoted the expansion of scissors by the flexible of linear motion unit (as hydraulic actuating cylinder etc.) and folded.It makes aloft work efficiency higher, and safety more ensures.

In scissor-type lifting platform common traditionally, one end of scissors mechanism is fixing, if this aspect ratio just causing lifting table to rise is higher, two support the side that force can lean against upper mounting plate, upper mounting plate is in state that one is similar to " cantilever beam ", the integral rigidity of such lifting table significantly reduces, and running stability reduces, the lifting of heavy goods cannot be completed, otherwise, if in order to the bearing capacity improving elevator, avoid the state occurring above-mentioned " cantilever beam ", lifting table two strong point distances need be made as far as possible far away, this just causes the adjustable height of lifting table very limited.

Utility model content

The purpose of this utility model is the problem overcoming traditional scissors mechanism lifting table bearing capacity inequality, the lifting table of traditional type is fixing owing to there being one end, the other end slides, have rise after acting point asymmetric, platform unbalance stress, to platform and folding rod rigidity requirement higher, the defect such as the limited and adjustable height of bearing capacity is inadequate, seek one and make platform stress equalization, bearing capacity is large, and structure is simply easy to the mechanical device realized.

For achieving the above object, the forming primarily of bottom parts, drive part, lifting mechanism and upper mounting plate part of this large bearing capacity scissor-type lifting platform.

Base plate: be made up of floor body (1), base plate pipe link fixed mount (3) and base plate chute (17);

Lifting mechanism: be made up of connecting rod (8), scissor folding rod (7), the short pipe link of base plate (16), the short pipe link of upper mounting plate (15), base plate hinged axle (2), upper mounting plate jointed shaft (13), the short jointed shaft of base plate scissor (4), the short jointed shaft of upper mounting plate scissor (14) scissors rod adapter shaft (9), roller (5);

Upper mounting plate part: be made up of upper mounting plate main body (11), upper mounting plate pipe link fixed mount (12) and upper mounting plate chute (10);

Drive part: drive part is linear electric motors (6), is arranged on floor body (1).

Lifting mechanism the superiors scissor folding rod and the short pipe link of upper mounting plate (15) supports upper mounting plate part and junction is hinged, and scissor folding rod and upper mounting plate to be rolled with the cooperation of upper mounting plate chute (10) by roller (5) and be connected, lifting mechanism is identical with the connection mode of upper mounting plate part with lifting mechanism with the connection mode of bottom parts; Drive part is made up of linear electric motors (6), is arranged on floor body (1).

This device is compared to its advantage of common scissors mechanism: two scissor folding rods of (1) symmetry all can be slided in chute by roller, and rise the same Distance Shortened stroke of drive part like this; (2) be connected in floor body and upper mounting plate main body by the short pipe link of base plate (16) and the short pipe link of upper mounting plate (15) in the middle of, ensure that lifting mechanism can vertical lift; (3) for upper mounting plate, the support suffered by it is about centrosymmetric all the time, which enhances the rigidity of upper mounting plate, improves the load-carrying capacity of upper mounting plate simultaneously; (4) for lifting mechanism, symmetrical scissor folding rod and link work full symmetric, this also increases the rigidity of junction, there will not be because motionless the caused stuck situation in side is moved in side.

Detailed description of the invention

By bottom parts, lifting mechanism, upper mounting plate part and drive part assemble respectively, bottom parts is fixed, two short pipe links of base plate (16) are hinged with the base plate pipe link fixed mount (3) on base plate by base plate hinged axle (2), the roller (5) of the scissor folding rod end of the lifting mechanism of both sides is placed in base plate chute (17), in like manner upper mounting plate also uses two short pipe links of upper mounting plate (15) hinged by upper mounting plate jointed shaft (13) and upper mounting plate pipe link fixed mount (12), the roller (5) of the scissor folding rod end of both sides is placed in upper mounting plate chute (10), drive part is arranged on base plate body (1).

Then linear electric motors (6) are utilized to drive, because the base plate pipe link fixed mount (3) on the short pipe link of base plate (16) and base plate is hinged, so the scissor folding rod of bottom utilizes base plate chute (17) bilateral symmetry of the roller (5) of head on base plate to slide, angle between two scissor folding rods is diminished, thus upper mounting plate main body (11) is risen, in like manner, in upper mounting plate part, because the short pipe link of upper mounting plate (15) and upper mounting plate pipe link fixed mount (12) are with hinged, so the connecting rod on top can only utilize the roller (5) of head bilateral symmetry in upper mounting plate chute (10) to slide, while such upper mounting plate bears a heavy burden and rises, its strong point has three, a centre-lock, two other strong point is about centrosymmetric all the time.

Because load force is about centrosymmetric all the time, substantially increase the heavy burden ability of upper mounting plate like this; Due to lifting mechanism both sides full symmetric, stressed is also balanced, there is not the stressed little situation in stressed large one side, improves the rigidity of lifting mechanism so equally, also can not cause stuck phenomenon; In addition on the one hand, because the scissor folding rod of both sides is symmetrical all the time, and whole device bearing capacity is large, and the stroke that such lifting table can be elevated is comparatively large, makes whole lifting table be provided with the distinguishing feature of Long Distances, large bearing capacity.
