The fixed driving screw lifting platform is simple in structure and can meet special working requirements, the function of a lifting platform can be realized to the maximum, and the optimal using effect is achieved. The fixed driving screw lifting platform comprises a base, a top plate, a shearing fork and a screw structure, wherein the shearing fork comprises an outer fork and an inner fork; the outer fork is connected with the inner fork through a bearing; one end of the outer fork is sleeved on the end of a lifting connection rod through a lower bearing; the lifting connection rod is fixed on the base; the other end of the outer fork is fixed on an upper bearing seat at one end of a top plate; one end of the inner fork is fixed on a lower bearing seat through a lower bearing; the other end of the inner fork is fixed at the other end of the top plate through an upper bearing; a screw nut is arranged in the middle of the lifting connection rod; the screw structure comprises a screw and a motor, the motor penetrates through one end of the screw and is locked through a locking nut, and the other end of the screw is matched with the screw nut.
Description
Technical field
The utility model relates to the elevator technology field, is specially fixed type and drives 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 all is 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 under some specific environment, still can not satisfy operating needs, as require to remain on for a long time a certain height, this is because how many hydraulic efficiency pressure systems can exist certain leakage in the situation that remains 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 utility model provides fixed type to drive the leading screw bay-lift, and 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 utility model is realized 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 the 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 the 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 the 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 the described lifting linking member, described screw structure comprises leading screw, motor, described motor passes described leading screw one end and by lock nut locking, the described leading screw other end cooperates with described feed screw nut.
The beneficial effects of the utility model are; whole elevating function is to finish under the driving of motor; electric machine rotation drives the leading screw rotation; and the moving lifting connecting rod will be cut fork and close up or open; thereby rise or fall top board; can be long-term so that lifting table remains on the certain level state does not change, obtain best result of use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Such as Fig. 1, shown in Figure 2, the utility model comprises 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 the 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 the 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 the 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 the lifting linking member 7, screw structure comprises leading screw 12, motor 13, motor 13 pass leading screw 12 1 ends and by lock nut 14 lockings, leading screw 12 other ends cooperate with feed screw nut 11.
Working process of the present utility model 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, closes up so that lifting linking member 7, will be cut fork toward moving right, 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.
