Abstract

A carrying cart for a storage shelf consists of a cart body 19, a cart cover 26, a travelling mechanism and a lifting mechanism, wherein the cart travels on the storage shelf in a control manner under the drive of a drive motor, hinges 10, 11 and 12 form a cross hinge group, a lifting motor 8 pulls a small hinge 25 through an eccentric link 3 for changing the opening angle of the hinge group, and pulls the hinge group through a shaft lever 20 to be inserted into one end of a chute 28, so the opening angle of the two groups of hinge arms is changed for realizing the lifting purpose. The carrying cart for the storage shelf has the advantages that the eccentric link pulls the large and the small hinge arm to change the opening angle of the large and small hinges so that the lifting purpose is realized; and the carrying cart for the storage shelf has a simple structure, and is simple in manufacturing process, convenient to assemble and simple to operate.

Description

Be used for the delivery dolly in the storage rack

Technical field

The present invention relates to a kind of storage facilities, particularly a kind of delivery dolly that is used in the storage rack.

Background technology

In the logistics progress of goods; Place, reasonable use warehouse is an important link that reduces logistics cost; Used modern up-to-date technology in a large number in the modern warehousing management; Wherein in goods is stacked, adopt shelf to concentrate and place, the means of delivery of goods in the shelf of special use delivers and is deposited on the storage rack, thereby not only practices thrift the place but also raise the efficiency.The means of delivery of the special use in service of the logistics equipment that is absolutely necessary in modern times.Thereby, the quality of the lifting mechanism of means of delivery influences the delivery efficient of warehoused cargo and the degree of utilization of storage rack and directly affecting the work efficiency of this means of delivery; See from the situation of existing private carrier or vehicle, roughly can be divided into following several types:

One. with eccentric bushing and eccentric shaft is the transport trolley of lifting mechanism form, like the Chinese invention patent application number: 200710159923.1.The adjustable height that its lifting structure form adopts eccentric bushing and eccentric shaft to realize that eccentric throw provides behind the circular movement is poor, but owing to the height of this up-down receives the restriction of eccentric throw, is under the situation of hypermutation or uneven load in carrying especially; Stressed member and strut member deform or produce when spending, and this type of transport trolley adjustable height will move interference, and walking and up-down are restricted; Be difficult to meet the requirements of height; In addition, the lifting process of transport trolley is higher to the precision prescribed of the machine up of cam, and the synchronism of going up and down in front and back is also comparatively strict; So just make the manufacturing cost of cam drive lifting mechanism higher, the requirement of Installation and Debugging is also comparatively complicated.

Two. combine the transport trolley of lever form with eccentric wheel, like the Chinese invention patent application number: 200380102575.4 as lifting mechanism.Because the restriction of working environment, the length of throw of lever is placed restrictions on, and needs a plurality of lever combination links to realize that motion process will produce the component of power, influences the efficient of work, and simultaneously, its stability is also relatively poor.

Summary of the invention

The objective of the invention is to the defective that exists in the prior art, a kind of delivery dolly that is used in the storage rack is provided.The present invention spurs big or small hinge arms reaches up-down with the folding angle that changes big small hinge purpose through eccentric link; The folding angle of big small hinge is interrelated and restriction; The maximum angle of release of small hinge is less than 180 °; Be the condition of controlling and adjustment is provided convenience; The brachium of size hinge arms the present invention includes through regulating the adjustable height that can improve transport trolley: be used to deliver dolly traveling gear that on the storage rack slide rail, moves and the lifting mechanism that is used to deliver the dolly up-down, traveling gear comprises drive motor 2, sprocket wheel 1, flower wheel 14, drive wheel 14a; Lifting mechanism comprises: lifting motor 8,

hinge

10,11,12, small hinge 25, eccentric link 3, key axle axle sleeve 5, key axle 6, locating support 7, chain-wheel mechanism 9, axostylus axostyle 20, support 27, chute 28, locating support 29; Drive motor 2 is through sprocket wheel 1, drive wheel 14a, flower wheel 14, and driving car body 19 by drive wheel 14a has control to go through control convenience on storage rack, it is characterized in that said

hinge

10,11,12 compositions one intersection hinge set; The delivery dolly is made up of two groups of hinge set; One end of hinge set is separately fixed on car body 19 and the car bonnet 26 through support 27, and the other end of hinge set inserts respectively in the chute 28 that is provided with on car body 19 and the car bonnet 26, and lifting motor 8 drives eccentric links 3 through chain-wheel mechanism 9 and key axle 6; The other end of eccentric link 3 is connected with small hinge 25; Pulling small hinge 25 changes the hinge set folding angle that hinge 10,11,12 is formed, and lifting motor 8 inserts an end of chute 28 simultaneously through axostylus axostyle 20 pulling hinge set, make 25 liang of groups of

hinge

10,11,12 and small hinge hinge arms change the folding angle.

The end of said eccentric link 3 and small hinge 25 center-point hinges, eccentric link 3 rotate a circle and drive small hinge 25 and make primary water square to moving back and forth.The center-point of

hinge

10,11,12 is directed mobile through locating support 7 and locating support 29 front and back, and locating support 7, locating support 29 are the directed moving structures in front and back.Said eccentric link 3, chain-wheel mechanism 9, be fixed on the key axle 6 by locking plate 4, the center-point of

hinge

10,11,12 also is fixed on the key axle 6 through key axle axle sleeve 5, and front and back are connected on two locating supports 7,29 and form an integral structure.

Advantage of the present invention spurs the purpose that big or small hinge arms reaches up-down through eccentric link, and the folding angle that changes big small hinge reaches the purpose of up-down, features simple structure of the present invention, and manufacture craft is simple, and is easy to assembly, simple to operate.
