Abstract
The invention discloses a hydraulic grab bucket. In the hydraulic grab bucket, two rotating shafts sequentially penetrate through axial holes at one side of a gear frame; when the rotating shafts are arranged, rotating arm positioning keys and sector gear positioning keys are arranged in corresponding key grooves of the rotating shafts; rotating arms and sector gears are arranged inside the gear frame, so that the axial holes of the rotating arms and the sector gears are aligned to the axes of the rotating shafts; the rotating shafts sequentially penetrate through the axial holes at one side of the gear frame, the axial holes of the rotating arms, the axial holes of the sector gears and axial holes at the other side of the gear frame; for ensuring that two sector gears are mutually symmetrical and are meshed and two rotating arms are kept in parallel, a cylinder body of the hydraulic cylinder and a piston rod are hinged at one ends of two force arms by using pin rolls; and two sides of the two grab buckets are fixedly arranged on the rotating shafts at two sides of the gear frame through grab bucket positioning keys.
Description
Technical field
The present invention relates to a kind of grab bucket, particularly a kind of hydraulic grab belongs to the weight-hauling equipment technical field.
Background technology
At the harbour, harbour, building site, factory and other place, often to load and unload powdery or granular substance.At present, being used for above-mentioned place to the grab bucket that powdery or granular substance load and unload, is to utilize lever principle basically on structure and principle, and the arm of force of lever is rotated under the effect of lifting self gravitation, realize the switching of grab bucket, thereby realize loading and unloading goods.The grab bucket of this principle and structure can't realize control according to specific circumstances owing to realize the action that opens and closes, and in the course of the work, often can not work better effectively, has the insecure shortcoming of work.
Summary of the invention
The objective of the invention is to: a kind of hydraulic grab is provided, and this grab bucket is in when work, do not rely on the gravity of self lifting, and it is existing to overcome existing grab bucket better: can not effectively work, have the insecure defective of work.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of hydraulic grab, it is by grab bucket, gear frame, rotating shaft, pivoted arm, bearing pin, quadrant gear, hydraulic actuating cylinder, the pivoted arm positioning key, the quadrant gear positioning key, the grab bucket positioning key is formed, it is characterized in that: described gear frame is rectangular structure, be installed in shaft parallel biography support above, described quadrant gear is by two identical forming, two quadrant gears are fixed on above the rotating shaft of gear frame in-to-in by the quadrant gear positioning key, form meshing relation between two quadrant gears, described pivoted arm is made up of two of equal length parameters, two arm of forces are fixed on above the rotating shaft of gear frame in-to-in by arm of force positioning key, simultaneously, the axis of two arm of forces is parastate, the cylinder body of described hydraulic actuating cylinder and piston rod are hinged on an end of two arm of forces respectively by bearing pin, simultaneously, make the axis of hydraulic actuating cylinder perpendicular with the axis of rotating shaft all the time in the space; Described grab bucket is by two identical forming, and the both sides of two grab buckets are fixed on above the rotating shaft of gear frame both sides by the grab bucket positioning key.
Principle of work of the present invention is: by hydraulic pressure when hydraulic cylinder piston rod inwardly shrinks, two pivoted arms inwardly rotate, pivoted arm drives two rotating shafts by the pivoted arm positioning key and does corresponding rotation, owing to have meshing relation between two quadrant gears, and two quadrant gears install and fix together with two rotating shafts respectively, so, the rotation of synchronously opposite both direction is done in two rotating shafts, so, rotating shaft just drives two grab buckets to synchronous the separating in both sides by the grab bucket positioning key, when the piston yearning of hydraulic actuating cylinder was stretched out, above-mentioned action was just in time opposite.
Beneficial effect: a kind of hydraulic grab of the present invention, the switching of its grab bucket do not rely on and conduct oneself with dignity and the strength that hoists, and open and close and be in synchronous regime, so, can realize effectively, work reliably.

The specific embodiment
Two rotating shafts (3) are passed from the axis hole of a side of gear frame (2) successively, when rotating shaft (3) is installed, pivoted arm positioning key (8) in advance, quadrant gear positioning key (9) is installed in the corresponding keyway of rotating shaft (2), simultaneously, with pivoted arm (4), the inside that is placed in gear frame (2) of quadrant gear (6), and make pivoted arm (4), the axis hole of quadrant gear (6) is aimed at rotating shaft (3) axis, with rotating shaft (3) successively from the axis hole of a side of gear frame (2), pivoted arm (4) axis hole, pass in the axis hole of an other side of the axis hole of quadrant gear (6) and gear frame (2), when above-mentioned installation, guarantee that two quadrant gears (6) are symmetrical, and keep ingear to concern, two pivoted arms (4) keeping parallelism, an end that respectively cylinder body and the piston rod of hydraulic actuating cylinder (7) is hinged on two arm of forces (4) with bearing pin (5) is fixed on the both sides of two grab buckets (1) above the rotating shaft (3) of gear frame (2) both sides by grab bucket positioning key (10).
Claims (3)
1. hydraulic grab, it is made up of grab bucket, gear frame, rotating shaft, pivoted arm, bearing pin, quadrant gear, hydraulic actuating cylinder, pivoted arm positioning key, quadrant gear positioning key, grab bucket positioning key, it is characterized in that: gear frame (2) is rectangular structure, rotating shaft (3) be installed in abreast transmission bracket (2) above, two quadrant gears (6) are fixed on above the rotating shaft (3) of (2) portion in the gear frame by quadrant gear positioning key (9), form meshing relation between two quadrant gears (6).
2. according to claims 1 described a kind of hydraulic grab, it is characterized in that: two arm of forces (4) are fixed on above gear frame (2) the in-to-in rotating shaft (3) by arm of force positioning key (8); The end that bearing pin (5) is hinged on two arm of forces (4) with the cylinder body and the piston rod of hydraulic actuating cylinder (7) respectively.
3. according to claims 2 described a kind of hydraulic grabs, it is characterized in that: the both sides of two grab buckets (1) are fixed on above the rotating shaft (3) of gear frame (2) both sides symmetrically by grab bucket positioning key (10).
