In existing rotary grab bucket, exist and can't be exactly accurately control the gyrobearing and the speed of grab bucket body, grasp force is little, and efficient is low, and the rotation process stationarity is poor, installs, defective such as during replacement cost.
Summary of the invention
The purpose of this utility model is: overcome the defective that exists in the above-mentioned rotary grab bucket, provide a kind of for supporting uses of engineering machinery such as crane, monobucket hydraulic crawler excavators, but complete cycle rotates, and can accurately control the anglec of rotation and speed exactly, grasp force is big, and stability of rotation is installed and changed hydraulic rotary grab bucket easily, operating efficiency during with the raising operation alleviates operator's working strength.
Technical solution of the present utility model is: the rotary grab bucket of a kind of engineering machinery, it is characterized in that: an energy is housed under the link makes the pivoting support that complete cycle rotates around it, the brace summer that connects a flanged dish below the pivoting support, the brace summer bilateral symmetry is installed two hydraulic cylinders, hydraulic cylinder is connected with the grab bucket body again, the grab bucket body is supported by brace summer, at the link upper offset driving pivoting support is installed and is made the drive unit that complete cycle rotates, described drive unit has two kinds of type of drive: fluid motor-driven and motor-driven, a measurement mechanism of measuring the pivoting support angle of revolution is installed on the described link, so that operating personnel etc. can control exactly to the grab bucket body, realize in 360 °, turning round at any angle.
Measurement mechanism described in the utility model is made up of encoder, shaft coupling, output shaft three parts, and the encoder of measuring corner is connected in output shaft on the flange by shaft coupling.
Drive unit fluid motor-driven described in the utility model and Motor Drive mode.Hydraulic cylinder adopts single hydraulic circuit to drive or two control modes that hydraulic circuit drives.
Compared with prior art, the utility model has following advantage:
1. simple in structure, applied widely, only need to change the design that connects otic placode and just can carry out operation in engineering machinery such as monobucket hydraulic crawler excavator, cranes, be applicable to that also the harbour unloading is peculiar to vessel.
2. be somebody's turn to do the highly versatile of grab bucket, difference according to manipulating object, only need the grab bucket body is designed, two grab bucket bodies can be just the same, also can be designed to difformity, other positions can be carried out similar Design according to this utility model and be got final product, and the resulting grab bucket scope of application is wider, alleviate designer's working strength in addition, thereby shortened the research and development design cycle of product greatly.
3. should grab bucket adopt double hydraulic cylinder to drive the switching of grab bucket, when adopting single drive circuit, (be fit to the identical occasion of grab bucket shape), synchronism is good, grasp force is big, and flexible movements (are fit to grab bucket shape occasion inequality) when adopting two loops to drive, the extracting scope is big, be fit to the several work object, grasp force is big, easy operation.
4. the encoder of measuring corner has been installed on the link of this grab bucket, thereby operating personnel can control grab bucket revolution at any angle in 360 ° of scopes, accurate positioning.
5. the drive unit of this rotation grab bucket is installed in the edge of link, can reduce to rotate the size of whole physical dimension, particularly vertical direction of grab bucket effectively, adopt the pivoting support of band external tooth type, compact conformation, speed reducing ratio is big, impact force is little, and is more steady during rotation.
