Abstract
A synchronous hydraulic multi-petal grab bucket features that a telescopic hydraulic cylinder is connected between upper and lower bearing beams, and all petals are synchronously opened or closed by changing the distance between upper and lower bearing beams. Its advantages are simple structure, more retional close/open manners, and lower cost.
Description
Type of the present invention belongs to loading-unload machine, also is applicable to automation and construction machinery and equipment.It is a kind of multi flap synchronous hydraulic grab bucket that utilizes telescopic oil cylinder for hydraulic actuator.
In the prior art, mechanical type can reach synchronous requirement, but it needs closed rope and a whole set of hoisting system, and the many lobes electric hydraulic bucket that utilizes telescopic oil cylinder to make can not be synchronous, and advertisement that 9 years second, third periodicals such as grade of " handling machinery " published as Beijing handling machinery research institute of Ministry of Machine-Building Industry are stepped on and Shanghai are played this Kate of sail and worn and receive the product introduction of mechanical Co., Ltd.
The purpose of type of the present invention is: overcome weak point of the prior art, provide a kind of structure simpler, method for opening and closing is more reasonable, and each lobe multi flap synchronous hydraulic grab bucket that can open and close synchronously.Because structural reason, the extracting ability of this grab bucket is stronger, is applicable to that hydraulic automobile hangs mobile operation, changes the shape of lobe, can improve the extracting ability to different blocks, improves its efficient.
The purpose of type of the present invention realizes in the following manner, a kind of multi flap synchronous hydraulic grab bucket, by deck beam (1), through beam (2), telescopic oil cylinder (3), lobe (4) and strut (5) are formed, its thing is levied and is: because the up-and-down movement of oil cylinder (3), changed the distance between last through beam, strut (5) will drive lobe (4) and rotate, thereby its each lobe is opened and closed synchronously, realized synchronous extracting to goods, what be worth proposition is that the present invention has essential distinction with my another multi flap synchronous hydraulic grab bucket of invention, has been to utilize different hydraulic actuators.
Purpose of the present invention further realizes in the following manner, when not having high-pressure and hydraulic oil source, multi flap synchronous hydraulic grab bucket, it is characterized in that: on through beam, set up the high-pressure and hydraulic oil input telescopic oil cylinder that pumping plant (6) produces pumping plant, by changing the spacing that goes up through beam, also can realize synchronous extracting to goods.
Multi flap synchronous hydraulic grab bucket is characterized in that the quantity of telescopic oil cylinder can have different quantity, but has importantly changed distance between last through beam by it.
Multi flap synchronous hydraulic grab bucket is characterized in that: for more effective extracting piece stone class block, the length of each lobe is lacked relatively every one, and the purpose of so doing is more effective extracting block.According to the size of block, can select the lobe of varying number.In addition, the closure means of arrogating to oneself formula of also can taking to shake realizes above-mentioned purpose.
Type of the present invention compared with prior art has following advantage:
1, makes many lobes synchronous mode grab bucket hydrofication.
2, structure is simpler, and method of closing is more reasonable.
3, Applicable scope is wider, and this grab bucket is not only applicable to wheel crane, mix pumping plant after, be applicable to any electrodynamic type crane.
4, each lobe is synchronous.
5, this grab bucket overload capacity is strong, and overload protection is safe and reliable.
6, this grab bucket cost is low.
Description of drawings: Fig. 1 is the multi flap synchronous hydraulic grab bucket that does not carry the high pressure liquid forced oil device.Fig. 2 is the multi flap synchronous hydraulic grab bucket that is equipped with pumping plant on the through beam.Below among each figure 1---deck beam; 2---through beam; 3---telescopic oil cylinder; 4---lobe; 5---strut; 6---pumping plant.
The present invention is described in further detail in conjunction with the accompanying drawings: the best way that realizes this invention is to link to each other with telescopic oil cylinder between last through beam, by the strut effect on the deck beam, each lobe is opened and closed synchronously, and test session can utilize hydraulic automobile to hang or hydraulic power source such as loader is finished.
Claims (3)
1, a kind of multi flap synchronous hydraulic grab bucket, form by deck beam 1, through beam 2, telescopic oil cylinder 3, lobe 4, strut 5 etc., it is characterized in that linking with telescopic oil cylinder between through beam, by the variation of last through beam spacing, under the effect of strut, each lobe is opened and closed synchronously, thereby realize extracting to goods, it is to be noted that the quantity of oil cylinder can select different quantity according to different article, the quantity of lobe is also like this in addition, the important point be if the bigger adjacent length of block however with.Moreover difformity such as that last through beam can be done is circular, oval, oblong, thereby difform multi flap synchronous hydraulic grab bucket is arranged.
2, according to right 1 described a kind of multi flap synchronous hydraulic grab bucket, it is characterized in that being equipped with on the through beam pumping plant, when not having the high pressure liquid potential source, the high-pressure and hydraulic oil that can utilize the pumping plant in the grab bucket to produce is realized the switching of grabbing bucket.
3, Zhua Dou switching can be made into intermittent mode according to the shape of grabbing object and opens and closes, so that to the bigger more effective extracting of block.
