Specific embodiment
To keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention is implemented with reference to the accompanying drawing
Mode is described in further detail.
As shown in Figure 1 and Figure 2, the present invention provides a kind of grab buckets of new Type of Hydraulic, including fuel tank 1, hydraulic pump 2, hydraulic pump
It stands 3, support frame, 4, two pieces of jaws being mutually twisted 5, as shown in figure 5, the plate point of two pieces of jaws 5 is in upper plate respectively in the embodiment
Point 20 and lower plate point 21, upper plate point 20 and lower plate point 21 are usually integrally cast with jaw 5 in the embodiment, upper plate point 20
The thickness of thickness and lower plate point 21 is respectively the half of 5 thickness of jaw, and when two pieces of jaws 5 are engaged, upper plate point 20 and lower plate
Point 21 fits, and the thickness and the sum of the thickness of lower plate point 21 of upper plate point 20 are equal with the thickness of jaw 5, in this way when grab bucket is being grabbed
Material can be effectively avoided to let out from the gap of two pieces of jaws 5 during taking the materials such as powder or particulate material.
Further include the hanger 6 that 3 top of hydraulic power unit is set, lifting lug 7 is equipped among the upper end of hanger 6, between hanger 6 and support frame 4
It is fixedly connected with the hydraulic cylinder 8 of vertically symmetrical setting, is conducive to grab bucket and keeps entire grab bucket during crawl and release
Stability, between hydraulic pump 2 and hydraulic cylinder 8 be equipped with oil inlet pipe 14 and oil return pipe 15.As shown in figure 4, the downside of support frame 4
Rotation axis 9 is respectively equipped between both ends and the both ends of two pieces of jaws 5, fixing sleeve is equipped with gear 10 in each rotation axis 9, ipsilateral
Two gears 10 in two rotation axis 9 are meshed, and have been respectively fixedly connected between the both ends of two pieces of jaws 5 horizontally disposed solid
Dead axle 11, fixing sleeve is set there are two spaced otic placode 12 in fixing axle 11, the company of being hinged between each otic placode 12 and hanger 6
The upper end of extension bar 13, connecting rod 13 is hinged with hanger 6 by pin shaft 16, and the lower end of connecting rod 13 and otic placode 12 are also by pin shaft
16 are hinged.Axle sleeve 17 is equipped between hanger 6 and pin shaft 16, axle sleeve 17 and pin shaft 16 are rotatablely connected, and axle sleeve 17 and hanger 6 are fixed
Connection, as shown in figure 3, offering mounting hole 18 on 17 inner wall of axle sleeve, is equipped with granular graphite 19, pin shaft 16 is in axis in mounting hole 18
Granular graphite 19 can be ground into powder during rotation in set 17, and graphite powder can play the role of lubrication to pin shaft 16, can begin
Two pieces of integralities jaw 5 closure and opened are kept eventually.
In use, when needing to grab material, the tailpiece of the piston rod of hydraulic cylinder 8 stretches out, and drives hanger 6 to moving up
Dynamic, hanger 6 drives two pieces of jaws 5 to open by connecting rod 13, grabs material, and then the tailpiece of the piston rod of hydraulic cylinder 8 retracts, band
Dynamic hanger 6 moves down, and hanger 6 drives two pieces of jaws 5 to be closed by connecting rod 13, hoisting mechanism and movement by crane
Material is transported to when the region of discharging by mechanism, is opened jaw 5 and is unloaded material.During use, in axle sleeve 17
The setting of granular graphite 19 can play lubricating action to pin shaft 16, this ensures that hinged between connecting rod 13 and hanger 6
It remains than smoothly, and can guarantee that two pieces of jaws 5 are engaged by the engagement of 9 gear 10 of rotation axis, upper plate point
20 and fitting for lower plate point 21 can effectively avoid grabbing bucket the shedding of when lifting by crane material material, guarantee the rule of Work places
It is whole, and then do not need to expend a large amount of manpower and financial resources and Work places are cleared up.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
