Abstract

A goods fork mechanism for a stacking machine comprises a base, an upper fork plate, a middle fork plate and a lower fork plate. Adjacent fork plates are connected with each other through drawing-inserting type structures and horizontally-guiding sliding guide rails are arranged between the adjacent fork plates so that the fork plates can slide relatively in a horizontal direction. Simultaneously, and a driving chain wheel group and a transmission chain wheel group are further arranged among the three fork plates. a gear and rack mechanism is installed between the lower fork plate and the base, a gear arranged on the gear and rack mechanism is connected to a motor through a transmission shaft, power is supplied by the motor which is located in a movable motor box arranged on the base so that the motor can perform synchronous advancing along with an upper rack, and accordingly a larger stroke space is further reserved. The goods fork mechanism for the stacking machine is simple in process, convenient to process, favorable for the improvement of working efficiency of the stacking machine and convenient to maintain.

Description

A kind of fork mechanism of stacker

Technical field

The utility model belongs to the warehousing management field, is specially a kind of fork mechanism of stacker that is used for cargo storage and extraction.

Background technology

Fork mechanism is the actuating unit of piler access goods, is installed on the loading platform of piler, is used for bearing goods and goes up and down, and can in the shelf of piler both sides, stretch out pallet fork, to remove or to put into goods.In order to reduce the width in tunnel; And have enough flexible strokes,, adopt multipole differential formula retractable fork mechanism usually according to the shape of pallet, the dimension and weight of unit goods etc.; Wherein, comparatively commonly used is secondary or three grades of straight line differential formula retractable fork mechanisms.

The employed piler pallet fork of present automatic stereowarehouse, because its unreasonable structure causes pallet fork from great, volume is big, and stock utilization is low, and the process-cycle is long.Therefore, the existing piler pallet fork flexible use in some middle-size and small-size warehouses that do not suit.

The utility model content

The technical matters that the utility model solved is to provide a kind of fork mechanism of stacker; Through the bi-directional expansion motion of driving chain wheels and messenger chain group control pallet fork is set; Simultaneously; The bottom adopts the cooperation of rack-and-gear to realize transmission and braking, in order to solve the technological deficiency that exists in the prior art.

The technical matters that the utility model solved adopts following technical scheme to realize:

A kind of fork mechanism of stacker is a symmetrical structure, is installed on the loading platform of piler; Can slide with respect to the bi-directional expansion that crane carry out on the horizontal direction, specifically comprise pedestal, on pitch plate, middle fork plate and lower fork plate; Link to each other through the draw and insert-type structure between the adjacent tine plate; And be provided with the slide rail of horizontally-guided, make the fork plate can carry out the slide relative of horizontal direction, simultaneously; Between three fork plates, also be provided with driving chain wheels and messenger chain wheels, fork plate and lower fork plate during said driving chain wheels connect through sprocket wheel; The messenger chain wheels then connect through sprocket wheel goes up fork plate and middle fork plate.

In the utility model, the stroke of messenger chain wheels is the twice of driving chain wheels stroke, is always the twice of lower fork plate with respect to the stroke of pedestal to guarantee the fork plate with respect to the stroke of pedestal.

In the utility model, the pinion and rack of a symmetry also is installed between lower fork plate and the pedestal, the upper rack end is installed in lower fork plate bottom; Upper rack is installed on the pedestal; Gear is positioned at the centre of upper and lower tooth bar, is connected to motor through transmission shaft, and motor is positioned on the pedestal a movably motor box; Make motor to advance synchronously, and then keep bigger stroke space with upper rack.

In the utility model, equipment provides power by the motor in the motor box, and said motor is preferably either-rotation motor.

In the utility model, the mode of motion of driving chain wheels and messenger chain wheels is interlock.

Beneficial effect: the utility model technology is simple, easy to process, can guarantee fork fork body can before and after bidirectional-movement; And length variations is flexible; Driving efficiency obviously improves when assurance fork body has enough strokes; Own wt also obviously alleviates, thereby, help improving the piler work efficiency.

Description of drawings

Fig. 1 is the scheme drawing of the preferred embodiment of the utility model;

Fig. 2 pitches the single-side structural detail view behind the plate for the utility model removes;

Fig. 3 is the pinion and rack scheme drawing in the utility model preferred embodiment.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

In the preferred embodiment referring to a kind of fork mechanism of stacker of Fig. 1; Between the fork plate is stepped construction, and three layers of fork plate are formed fork plate assembly 3 jointly, and left-right symmetric distributes; The front end of fork plate assembly 3 is provided with front end gear device 1 and rear end gear device 6; Driver train is a two-way motor 4, and motor 4 is positioned on the motor cabinet 2, and type of drive is that motor 4 carries out transmission through finishing bevel gear cuter 5 drive drive links 7.

For the inner structure of present embodiment is more clear; In the single-side structural detail view of the fork plate assembly 3 that removes present embodiment shown in Figure 2; Motor 4 drives drive link 7 through finishing bevel gear cuter 5 and carries out transmission; And moment of torsion outputed to transmission gear 12, transmission gear 12 is fixed on the lower fork plate on the chain 11 through 11 transmissions of ingear tooth bar; Lower fork plate and middle fork plate and going up between the fork plate is connected through two chains 10, wherein, through pulley 5 also transmissions of reinforcing, support through slide block 9 between middle fork plate and the last fork plate and pitch plate, and it is spacing to utilize slideway 14 to carry out between middle fork plate and the lower fork plate.

In the pinion and rack scheme drawing in the utility model preferred embodiment shown in Figure 3; Following tooth bar 1102 is fixed on the pedestal, upper rack 1101 is installed on the lower fork plate; Transmission gear 12 is positioned in the middle of upper rack 1101 and the following tooth bar 1102; When making drive of motor, motor cabinet 2 together moves with the lower fork plate through ingear tooth bar 11.

In the present embodiment,, reduce friction therebetween simultaneously, also be equipped with insurance bar 13 for guaranteeing that between the fork plate be tolerance clearance.

More than show and described the advantage of groundwork, principal character and the utility model of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
