Abstract
The utility model discloses a novel hydraulic grab which comprises a hydraulic grab bucket body and a driving device. The driving device comprises a hydraulic rotary motor and a rotary transmission mechanism, a mounting plate for mounting the rotary transmission mechanism is arranged on the top of the hydraulic grab bucket body, the hydraulic rotary motor is in transmission connection with the rotary transmission mechanism, and the rotary transmission mechanism is a worm and gear transmission mechanism. The rotary transmission mechanism of the novel hydraulic grab is the worm and gear transmission mechanism with a characteristic of reverse self-locking, and a high reduction ratio can be obtained in a transmission process. Compared with the prior art, the novel hydraulic grab has the advantages of high working stability and safety coefficient, a speed reducer for increasing the reduction ratio is not required to be purchased during large engineering operation, and accordingly the service cost and the machine failure rate can be greatly reduced.
Description
Technical field
The utility model relates to a kind of engineering machinery, particularly a kind of hydraulic gripping apparatus.
Background technology
Hydraulic gripping apparatus, it is a kind of handling instrument with hydraulically powered gripper formula, use matches with multiple small engineering machineries such as hydraulic crawler excavator, hydraulic loader, hydraulic crane and hydraulic excavators, be widely used in stevedoring, the loading of foundation ditch excavation, dell excavation and the mud of building lot, sand, coal, rubble.
In known technology, hydraulic gripping apparatus generally comprises hydraulic grab body and drive unit, this drive unit comprises hydraulic rotating motor and rotating actuator, this hydraulic rotating motor is controlled the opening and closing of hydraulic grab body on the one hand, control on the other hand the rotation of hydraulic grab body by rotating actuator, this rotating actuator is gear drive.The hydraulic gripping apparatus of this kind structure, because rotating actuator is gear drive, and gear drive easily causes the job stability of hydraulic grab body and safety factor all lower without the reverse self-locking characteristic; Simultaneously, gear drive resulting deceleration when transmission is smaller, and the user need purchase in addition a reductor and improves speed reducing ratio in the large-engineering operation, has greatly increased user's use cost, and has increased the mechanical disorder generation rate.
In view of this, the inventor conducts in-depth research the defects of hydraulic gripping apparatus, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of novel hydraulic gripping apparatus, and it can improve job stability and safety factor greatly, and can reduce use cost and the mechanical disorder generation rate of user in the large-engineering operation.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of novel hydraulic gripping apparatus, comprise hydraulic grab body and drive unit, this drive unit comprises hydraulic rotating motor and rotating actuator, and the top of this hydraulic grab body is provided with the installing plate of installing for rotating actuator, and this hydraulic rotating motor and this rotating actuator are in transmission connection; Above-mentioned rotating actuator is Worm and worm-wheel gearing.
Above-mentioned Worm and worm-wheel gearing is horizontal one pole Worm and worm-wheel gearing.
The worm gear of above-mentioned Worm and worm-wheel gearing fixedly is stacked on the above-mentioned installing plate, and the worm screw of above-mentioned Worm and worm-wheel gearing is fixedly connected with the output shaft of above-mentioned hydraulic rotating motor.
A kind of novel hydraulic gripping apparatus of the present utility model, because rotating actuator is Worm and worm-wheel gearing, Worm and worm-wheel gearing has the reverse self-locking characteristics, and can obtain relatively large speed reducing ratio in transmission process; Compared with prior art, hydraulic gripping apparatus of the present utility model has job stability and the high characteristics of safety factor, need not to purchase in addition one simultaneously and improve the reductor that speed reducing ratio is used in the large-engineering operation, can greatly reduce use cost and mechanical disorder generation rate.

Installing plate 3
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
A kind of novel hydraulic gripping apparatus of the present utility model, as shown in Figure 1, comprise hydraulic grab body 1 and drive unit, this drive unit comprises hydraulic rotating motor (not shown) and rotating actuator 2, the top of this hydraulic grab body 1 is provided with the installing plate 3 of installing for rotating actuator 2, this hydraulic rotating motor and this rotating actuator 2 are in transmission connection, this hydraulic rotating motor is controlled the opening and closing of hydraulic grab body 1 on the one hand, controls on the other hand the rotation of hydraulic grab body 1 by rotating actuator 2.Operating principle and the installation site of the hydraulic rotating motor of hydraulic gripping apparatus are identical in the operating principle of hydraulic rotating motor of the present utility model and installation site and the prior art, and the inventor is not repeated at this.
Improvements of the present utility model are: described rotating actuator 2 is Worm and worm-wheel gearing, this Worm and worm-wheel gearing is horizontal one pole Worm and worm-wheel gearing, and the worm gear 21 of this Worm and worm-wheel gearing fixedly is stacked on the installing plate 3, and the worm screw 22 of Worm and worm-wheel gearing is fixedly connected with the output shaft of hydraulic rotating motor.
A kind of novel hydraulic gripping apparatus of the present utility model, because rotating actuator 2 is Worm and worm-wheel gearing, Worm and worm-wheel gearing has the reverse self-locking characteristics, and can obtain relatively large speed reducing ratio in transmission process; Compared with prior art, hydraulic gripping apparatus of the present utility model has job stability and the high characteristics of safety factor, need not to purchase in addition one simultaneously and improve the reductor that speed reducing ratio is used in the large-engineering operation, can greatly reduce use cost and mechanical disorder generation rate.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
