Abstract
The utility model relates to a hydraulic grab bucket which is provided with asymmetric special-shaped jaw plates and can be used for grabbing cargoes in water, which belongs to cranes. The utility model is used for load hanging elements or devices of the cranes, winches, hoisters or tackles. The utility model is characterized in that one side of the grab bucket is composed of bow-shaped jaw plates, and each group of the bow-shaped jaw plates are parallelly and equidistantly installed on short steel pipes by toothed plates and form a bow-shaped comb net; an oil cylinder is controlled and driven synchronously by an electromagnetic valve; the other side of the grab bucket is composed of straight jaw plates, and each group of the bow-shaped jaw plates are parallelly and equidistantly installed on guide tubes by the straight toothed plates; the guide tubes are installed on the tube bases of guide bars, and the oil cylinder is controlled and driven synchronously by another electromagnetic valve; guide wheels which lead the grab bucket to slide along the wall are also installed on one side of the grab bucket. The utility model solves the problem that garbage is difficult to clean in a water tank of which the width is small, the garbage on the wall of the water tank can also be cleared by the utility model and water can leak from the spacing. The utility model can improve the efficiency that the grab bucket grabs sundries in the water tank of which the width is small, and particularly, the effect is remarkable when the utility model is used for clearing away the sundries, such as a dirt obstructing groove of a water reservoir, etc.
Description
Technical field
The utility model relates to a kind ofly can grasp the hydraulic grab that goods has asymmetric special-shaped jaw in water, belong to hoisting crane; The load suspension member or the device that are used for hoisting crane, capstan engine, winch or coaster.
Background technology
In known technology, the jaw of grab bucket is generally two jaws, the two pawls of bending or with many jaws of ball center's symmetry etc.The grab bucket of its weak point opens that to grasp the shared horizontal area of goods too big and can not be the refuse cleaning on dam wall groove or the ditch wall, example: grab rubbish in the dirty groove (grid) blocking of the less reservoir of width, general grab bucket is difficult to put in the groove (grid), and can not remove the rubbish foreign material that are attached on groove (grid) wall, the unpowered grab bucket of normal use can not be satisfied need of work.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and hydraulic grab that a kind of asymmetric special-shaped jaw is provided, this grab bucket is opened grasp the shared horizontal area of goods more half as large approximately than similar grab bucket; The side of grabbing bucket is arc multiple tooth jaw, and opposite side is the multiple tooth jaw of straight shape, and is furnished with leading sheave, and two side jaws can be used hydraulic-driven respectively, and grabbing between cog has the spacing space to have the sluicing function, fully satisfies need of work.
The purpose of this utility model can reach by following measure:
One side of grab bucket is made up of 6 groups of arc multiple tooth jaws, and every group forms arc comb net by 5 equidistant being installed in parallel in of arc tooth plate on the steel pipe, and it is by 6 oil cylinder driven in synchronism of 1 solenoid control; The opposite side of grab bucket is made up of 2 groups of multiple tooth jaws of straight shape, and every group by 9 equidistant being installed in parallel on the guide pipe of straight shape tooth plate, and guide pipe is installed on the base that leads, and it is by 2 oil cylinder driven in synchronism of other 1 solenoid control; Opposite side in grab bucket is also installed 4 leading sheaves, and grab bucket can be slided along straight wall.
The utility model is compared with original technology has following advantage: it is more half as large approximately than similar grab bucket that the shared horizontal area of extracting goods is opened in this grab bucket, in less the blocking in the sump (grid) of width, this grab bucket can be removed the rubbish on tank (grid) wall, and extracting rubbish, water can leak from tooth plate spacing space.This novel structure, easy to use of grabbing bucket has solved a difficult problem that removes rubbish in less tank of width or ditch, improved service efficiency, and remarkable result is arranged when removing groove (grid) foreign material in narrow and small river course especially.

The specific embodiment
Describe in detail according to the concrete scheme that the utility model proposes below in conjunction with legend:
Multiple tooth jaw 9 inside lugs of hydraulic grab 6 arc multiple tooth jaw 7 guiding base 8 straight shapes 10 arc jaw electromagnetic valve 11 straight shape jaw electromagnetic valve 12 short steel pipes 13 arc tooth plate 14 straight shape jaw oil cylinder 15 guide pipes 16 straight tooth plates 17 of track adjusting wheel 1 outside lug 2 main frames 3 motors 4 arc jaw oil cylinder 5 asymmetric special-shaped jaws
In accompanying drawing 1, the hydraulic grab of asymmetric special-shaped jaw (6) is closed condition, it is made up of main frame (3), motor (4), track adjusting wheel (1), arc jaw oil cylinder (5), arc multiple tooth jaw (7), the straight multiple tooth jaw of shape (9) etc., and the upper end of main frame (3) is installed with outside lug (2).Track adjusting wheel (1) be installed in pairs main frame (3) homonymy both sides and with the multiple tooth jaw of straight shape (9) at homonymy, two ends of arc jaw oil cylinder (5) are hinged with main frame (3) and arc multiple tooth jaw (7) respectively, and straight shape jaw oil cylinder (15), guiding base (8) and the straight multiple tooth jaw of shape (9) and main frame (3) are hinged.
In accompanying drawing 2, the hydraulic grab of asymmetric special-shaped jaw (6) when its track adjusting wheel (1) can move downward with crane rope, rolls downwards along groove (grid) wall in opened condition.
In accompanying drawing 3, motor (4) and arc jaw electromagnetic valve (11), straight shape jaw electromagnetic valve (12) are installed in the main frame (3).The upper end of main frame (3) also is installed with (10) 2 of inside lugs.Arc jaw electromagnetic valve (11) is by the synchronized operation of 6 arc jaw oil cylinders (5) control, 6 groups of arc multiple tooth jaws (7), its every group arc multiple tooth jaw (7) be by the equidistant parallel installation of 5 arc tooth plates (14), and be connected into arc comb net with short steel pipes (13).
