Abstract
The invention provides a fixed type drive lead screw lifting platform which is simple in structure and capable of satisfying special work requirements, enabling the lifting platform to function to the largest extent, and obtaining an optimal using effect. The fixed type drive lead screw lifting platform comprises a base seat, a top plate and a scissor fork which comprises an outer fork and an inner fork. The inner fork and the outer fork are connected through a bearing. The end portion of one end of the outer fork is connected to the end portion of a lifting connecting rod in a sleeved mode through a lower bearing. The lifting connecting rod is fixed on the base seat. The other end of the outer fork is fixed on an upper bearing seat of one end of the top plate. One end of the inner fork is fixed on a lower bearing seat through a lower bearing, and the other end of the inner fork is fixed on the other end of the top plate through an upper bearing. The fixed type drive lead screw lifting platform further comprises a lead screw structure. A lead screw nut is arranged in the middle of the lifting connecting rod. The lead screw structure comprises a lead screw and a motor which penetrates through one end of the lead screw and is locked through a locking nut. The other end of the lead screw is matched with the lead screw nut.
Description
Technical field
The present invention relates to the elevator technology field, be specially a kind of fixed type and drive the leading screw bay-lift.
Background technology
Bay-lift is the elevator machinery of a kind of vertical shipper or material resources, mainly for the production of goods handling between the conveyor line diff-H, bay-lift is equipped with various planes load transfer device toward contact, and the connecting device as the differing heights travel line is widely used in the operations such as high-level installation, maintenance.Lifting table commonly used is all to adopt hydraulic-driven at present, hydraulic-driven has the advantages that to drive great efforts, also can satisfy in the ordinary course of things the requirement of long-time pressurize, but still can not satisfy operating needs under some specific environment, as require to remain on for a long time a certain height, this is because can there be certain leakage in hydraulic efficiency pressure system in the situation that remain on for a long time a certain state, causes pressure to reduce, and causes the height of lifting table work top to reduce.
Summary of the invention
For the problems referred to above, the invention provides a kind of fixed type and drive the leading screw bay-lift, it is simple in structure, can satisfy special work requirements, and can bring into play to greatest extent the function of lifting table, obtains best result of use.
the present invention realizes by following proposal: it comprises base, top board, cut fork, the described fork of cutting comprises outer fork, interior fork, described outer fork, connect by bearing between interior fork, described outer fork one end end is connected to the lifting linking member end by lower bearing sleeve, described lifting linking member is fixed on described base, the described outer fork other end is fixed on the top chock of described top board one end, described interior fork one end is fixed on step by described lower bearing, the described interior fork other end is fixed in the described top board other end by head bearing, it is characterized in that: it also comprises screw structure, be provided with feed screw nut in the middle of described lifting linking member, described screw structure comprises leading screw, motor, described motor passes described leading screw one end and locks by lock nut, the described leading screw other end coordinates with described feed screw nut.
The invention has the beneficial effects as follows; whole elevating function is to complete under the driving of motor; electric machine rotation drives the leading screw rotation; and the moving lifting connecting rod will cut the fork close up or open; thereby rise or fall top board; can be long-term make lifting table remain on the certain level state not change, obtain best result of use.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
as Fig. 1, shown in Figure 2, the present invention includes base 1, top board 2, cut fork, cut fork and comprise outer fork 3, interior fork 4, outer fork 3, connect by bearing 5 between interior fork 4, outer fork 3 one end ends are socketed on lifting linking member 7 ends by lower bearing 6, lifting linking member 7 is fixed on base 1, outer fork 3 other ends are fixed on the top chock 8 of top board 2 one ends, interior fork 4 one ends are fixed on step 9 by lower bearing 6, interior fork 4 other ends are fixed in top board 2 other ends by head bearing 10, it also comprises screw structure, be provided with feed screw nut 11 in the middle of lifting linking member 7, screw structure comprises leading screw 12, motor 13, motor 13 passes leading screw 12 1 ends and locks by lock nut 14, leading screw 12 other ends coordinate with feed screw nut 11.
Working process of the present invention is: during motor 13 forward, drive leading screw 12 rotations, leading screw 12 drives feed screw nut 11 and carries out right straight-line motion, makes lifting linking member 7 toward moving right, and will cut fork and close up, thereby top board 2 is risen; During motor 13 counter-rotating, drive leading screw 12 counter-rotatings, leading screw 12 drives feed screw nuts 11 traveling priority of turning left, and will cut fork and open, thereby top board 2 is fallen.
