Abstract
The utility model discloses a tray platform lifting mechanism which comprises a chassis, a tray platform, a lifting device and a drive air cylinder. The tray platform lifting mechanism is characterized in that the lifting device comprises a pair of cross levers, one end of one lever and one end of the other lever of the pair of cross levers are respectively hinged with the chassis and the tray platform, idler wheels at the other ends of the pair of cross levers are respectively arranged in a chassis guide groove and a tray platform guide groove. A connecting rod is arranged between idler wheels in the chassis guide groove, the drive air cylinder is horizontally installed on the outer side of the lifting device, and an output shaft of the drive air cylinder is connected with the connecting rod in a perpendicular mode. Due to the facts that a drive mechanism is arranged on the chassis, the lifting device is arranged below a tray, the gravity center of power equipment is low, and operation is stable. The tray platform lifting mechanism has the advantages of being simple in structure, low in manufacturing cost of equipment, and capable of greatly reducing warehouse energy consumption of trays (pallets).
Description
Technical field
The present invention relates to elevator and palletizing mechanical technical field, specifically a kind of tray platform lifting mechanism.
Background technology
Piler is that a kind of work piece as prescribed pattern with packed or case dress is piled up neatly the automation equipment of operation at the dull and stereotyped enterprising windrow that rises and falls.The tray platform lifting mechanism is the critical component of piler, and it is mainly used in carrying material buttress or pallet in piler, and presses needs traction material buttress or the pallet fast lifting of job procedure, realizes the operations such as stacking.Traditional tray platform lifting mechanism mainly contains three kinds of work structuring modes: a kind of is the dull and stereotyped cylinder jacking mode that overhangs, another kind is the dull and stereotyped circumversion chain type of drive that overhangs, their common ground is that flat board overhangs, monolateral driving, without the pouring weight balance, but their complex structure is difficult in maintenance, and the energy consumption in practical application is higher; Also has a kind of mode, exactly dynamical axis is arranged on a side at main machine frame top, driven shaft is arranged on the opposite side at main machine frame top, motor is arranged on main machine frame, its output shaft is connected with dynamical axis and drives dynamical axis, and this structure lifting power device is arranged on the top of lifting rack, although can realize fast lifting, but whole device center of gravity is high, volume is large, poor stability.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tray platform lifting mechanism of simple in structure, good stability is provided.
Purpose of the present invention realizes by following technical scheme: a kind of tray platform lifting mechanism, comprise chassis, tray platform, lifting device, driving cylinder, it is characterized in that, described lifting device comprises the pair of cross lever, the right end of lever that intersects is hinged with chassis and tray platform respectively, and the roller of the other end is separately positioned in chassis guide groove and tray platform guide groove; Be provided with connecting rod between roller in the guide groove of chassis; Described driving cylinder level is arranged on the outside of lifting device, and the output shaft that drives cylinder is connected with connecting rod is vertical.
Further, four of the chassis angles are provided with highly identical spacing.
The beneficial effects of the utility model are: drive cylinder promotion lifting device and do horizontal balance, the horizontal balance of lifting device is converted into the perpendicular movement of tray platform.When pallet weight is lighter, can control and heighten the actuating speed that drives cylinder, lifting device operates in high-speed region, can realize fast lifting.When pallet weight is heavier, can control and turn down the actuating speed that drives cylinder, it is regional that lifting device operates in the large hoisting force of low hoisting speed.This device is arranged on driver train on the chassis, and lifting device is positioned at the below of pallet, and the center of gravity of power plant is low, moves more steady.This apparatus structure is simple, and the device fabrication cost is low, uses this device can significantly reduce pallet (pallet) storehouse energy consumption.

The specific embodiment
Below in conjunction with accompanying drawing, concrete enforcement of the present invention is described further.
A kind of tray platform lifting mechanism, comprise chassis 1, tray platform 2, lifting device 3, drive cylinder 4, it is characterized in that, described lifting device 3 comprises pair of cross lever 5, the right end of lever that intersects is hinged with chassis 1 and tray platform 2 respectively, and the roller 9 of the other end is separately positioned in chassis guide groove and tray platform guide groove; Be provided with connecting rod 6 between roller in the guide groove of chassis; Described driving cylinder 4 levels are arranged on the outside of lifting device 3, and the output shaft 7 that drives cylinder 4 is connected with connecting rod 6 is vertical.Four angles on chassis 1 are provided with highly identical spacing 8.
During operation, place some pallets or pallet on tray platform, drive the output shaft drivening rod horizontal reciprocating movement of cylinder, connecting rod drives roller horizontal reciprocating movement in chassis guide groove and tray platform guide groove, intersect lever to rotating around point of crossing, realize the tray platform up-and-down motion, realize the lifting of pallet or pallet, for next step crawl pallet or pallet are got ready.Identical spacing of the height that arranges on four angles on chassis can be controlled the tray platform falling head, prevents because of the too low damage that may cause lifting device of lowering position.
Claims (2)
1. tray platform lifting mechanism, comprise chassis, tray platform, lifting device, driving cylinder, it is characterized in that: described lifting device comprises the pair of cross lever, the right end of lever that intersects is hinged with chassis and tray platform respectively, and the roller of the other end is separately positioned in chassis guide groove and tray platform guide groove; Be provided with connecting rod between roller in the guide groove of chassis; Described driving cylinder level is arranged on the outside of lifting device, and the output shaft that drives cylinder is connected with connecting rod is vertical.
