Abstract
A full hydraulic control gripping device used on an excavator includes a connecting bracket, an assembled bearing seat, a gripping jaw, a hydraulic rotary motor, a hydraulic cylinder, a connecting plate and lugs, wherein the connecting bracket is connected to the upper part of a housing of the assembled bearing seat; a rotary core shaft of the hydraulic rotary motor is connected with a flange at the upper part of a core shaft of the assembled bearing seat through a bolt; a housing of the hydraulic rotary motor is fixed on the connecting bracket; the gripping jaw is hinged on the connecting plate at the lower part of the assembled bearing seat through an articulated shaft; and one end of the hydraulic cylinder is hinged to the connecting plate, while the other end thereof is hinged to the two lugs of the gripping jaw. When the connecting bracket of the device is lifted and overturned through the tail end of a bucket arm of the excavator, the weight and the bending moment of the whole gripping jaw are borne by the assembled bearing seat and the connecting bracket, the hydraulic rotary motor only controls the rotation of the whole mechanism without bearing any gravity and bending moment, therefore the hydraulic rotary motor is prevented from being damaged by the bending moment, and the strength and the rigidity of the whole gripping device are greatly improved.
Description
Technical field
The utility model belongs to the small engineering machinery field, relates to a kind of grabbing device that is used for all-hydraulic control on the excavator.
Background technology:
At present, the equipped annex that is applied to domestic small engineering machinery multi-function operation is a lot, for example: when many places utilize stalk shape material such as excavator shipment timber, sugarcane, need on excavator, be equipped with grabbing device, this device generally all will connect with the dipper of excavator is terminal by the shell of hydraulic gyration motor, the mandrel of rotary motor is connected with the claw of grabbing device, the upset of the flexible realization entire mechanism by the excavator boom upper cylinder.Though this structure is simple and practical, installing/dismounting is also more convenient, and the moment of flexure that the weight of grabbing device and material and when upset thereof form in practical operation is born by the hydraulic gyration motor entirely, and it is very fast to make hydraulic motor damage.Therefore, develop a kind of rational in infrastructure, functional performance good, and the hydraulic gyration motor on the excavator avoids bearing the grabbing device of gravity and moment of flexure, will be subjected to user's favor.
The utility model content:
The purpose of this utility model is to overcome the shortcoming of above-mentioned existence, provide a kind of rational in infrastructure, functional performance good, slew gear can adopt hydraulic motor also can adopt the grabbing device that is used for all-hydraulic control on the excavator of hydraulic oil cylinder driving.
The utility model can achieve the above object by the following technical programs: be used for the grabbing device of all-hydraulic control on the excavator, comprise link, assembling bearing support, gripper, hydraulic gyration motor, hydraulic jack, junction plate, journal stirrup; Link is connected assembling bearing support shell upper, the revolution mandrel of hydraulic gyration motor is connected with bolt with the mandrel upper flange of assembling bearing support, the shell of hydraulic gyration motor is fixed on the link, gripper is hinged on the junction plate of assembling bearing support bottom by jointed shaft, hydraulic jack one end is hinged on the junction plate, and the other end is hinged on the journal stirrup of two grippers.
Being connected to of gripper and journal stirrup is affixed.The mandrel center of gripper, hydraulic jack, journal stirrup and assembling bearing support is for hinged symmetrically.
The utility model adopts the good effect that produces after the technique scheme to be: link promotes and during upset by the dipper of excavator is terminal, the weight of whole gripper and moment of flexure are born by assembling bearing support and link, the hydraulic gyration motor is only controlled the revolution of entire mechanism, and does not bear any gravity and moment of flexure.Thereby protection hydraulic gyration motor is avoided moment of flexure and is destroyed, and has also improved the intensity and the rigidity of whole grabbing device.
Description of drawings:
Accompanying drawing is the structural representation that the utility model is used for the grabbing device of all-hydraulic control on the excavator.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as shown in the figure, be used for the grabbing device of all-hydraulic control on the excavator, comprise link 1, assembling bearing support 2, gripper 3, hydraulic gyration motor 4, hydraulic jack 5, junction plate 6, journal stirrup 7; Link 1 usefulness bolt is connected assembling bearing support 2 shell upper, the revolution mandrel of hydraulic gyration motor 4 is connected with bolt with the mandrel upper flange of assembling bearing support 2, the shell of hydraulic gyration motor 4 is fixed on the link 1, gripper 3 is hinged on the junction plate 6 of assembling bearing support 2 bottoms by jointed shaft, hydraulic jack 5 one ends are hinged on the junction plate 6, and the other end is hinged on and is connected with on 7 two grippers 3 of journal stirrup.The mandrel center of gripper 3, hydraulic jack 5, journal stirrup 7 and assembling bearing support 2 is for hinged symmetrically.
During work, link 1 is installed in the excavator boom end, by the control of the oil cylinder on excavator boom upset; promote by dipper; lifting force and tilting force are born by assembling bearing support 2 and link 1, and hydraulic gyration motor 4 does not bear any gravity and moment of flexure, thereby has protected rotary motor 4.During action, at first under rotary motor 4 drove, link 1 bottom junction plate 6 can be realized 360 ° of revolutions, and the contraction of two hydraulic jacks 5 with stretch out, can drive two grippers 3 by journal stirrup 7 opens and closes up, the relieving when realizing grabbing thing with pick up.
