Abstract
The utility model discloses a buffer device, and in particular relates to a buffer device for a hydraulic cylinder. The buffer device comprises a hammer body, a connector and a hydraulic cylinder, and is characterized in that one end of the connector is fixedly connected with the hammer body; the other end of the connector is provided with a mounting groove; the hydraulic cylinder is provided with a piston rod which extends to the mounting groove; a retainer ring is arranged at one end, which extends to the mounting groove, of the piston rod; the end part of the mounting groove of the connector is matched with the piston rod through a gland; and a buffer piece is arranged between the retainer ring and the gland. The buffer device is reasonable in design, and the service life of the hydraulic cylinder can be effectively prolonged.
Description
Technical field
The utility model relates to a kind of damping device, particularly relates to a kind of hydraulic oil cylinder cushion.
Background technique
Hydraulic jack one end of hydraulic hammer kind equipments such as present domestic hydraulic pile driver is installed on the frame; The other end connects with flange plate or hammer body; Its shortcoming is a hammer body when impacting, and impacts with bounce-back acting directly on the hydraulic cylinder piston rod, and the complete machine vibrations are big; Noise is big, thereby causes reduce the working life of hydraulic jack.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of impact and noise can reduce hammering the time, thus a kind of hydraulic oil cylinder cushion that prolongs the working life of hydraulic jack.
A kind of hydraulic oil cylinder cushion of the utility model; Comprise hammer body, connector and hydraulic jack, an end of said connector is fixedly connected with hammer body, and the other end of connector is provided with mounting groove; Said hydraulic jack is provided with the piston rod that extends to said mounting groove; The end that said piston rod extends to mounting groove is provided with back-up ring, and matching through gland with piston rod in the mounting groove end of said connector, is provided with shock absorber between said back-up ring and the gland.
A kind of hydraulic oil cylinder cushion of the utility model, said shock absorber is processed for the rubber material.
A kind of hydraulic oil cylinder cushion of the utility model, said connector is fixed through locating stud and said hammer body.
Compared with prior art the beneficial effect of the utility model is: because an end of connector is fixedly connected with hammer body; The other end of connector is provided with mounting groove; Hydraulic jack is provided with the piston rod that extends to mounting groove; The end that piston rod extends to mounting groove is provided with back-up ring, and matching through gland with piston rod in the mounting groove end of connector, is provided with shock absorber between back-up ring and the gland; The reaction force that when the hammering operation, produces of hammer body acts on the shock absorber through connector, back-up ring like this; Alleviating the back through shock absorber is being transmitted on the piston rod; Bounce-back campaign, vibration and the noise of reaction force, hammer body are all significantly subdued; The utility model is reasonable in design, can effectively prolong the working life of hydraulic jack.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Referring to Fig. 1, a kind of hydraulic oil cylinder cushion of the utility model comprises hammer body 1, connector 2 and hydraulic jack 3, and connector 2 is fixing with hammer body 1 through locating stud 9.The other end of connector 1 is provided with mounting groove 4; Hydraulic jack 3 is provided with the piston rod 5 that extends to mounting groove 4; The end that piston rod 5 extends to mounting groove 4 is provided with back-up ring 6, and matching through gland 7 with piston rod 5 in mounting groove 4 ends of connector 2, is provided with shock absorber 8 between back-up ring 6 and the gland 7; Shock absorber 8 is processed for the rubber material
The utility model embodiment is owing to an end of connector 2 is fixedly connected with hammer body 1; The other end of connector 2 is provided with mounting groove 4; Hydraulic jack 3 is provided with the piston rod 5 that extends to mounting groove 4; The end that piston rod 5 extends to mounting groove 4 is provided with back-up ring 6, and matching through gland 7 with piston rod 5 in mounting groove 4 ends of connector 2, is provided with shock absorber 8 between back-up ring 6 and the gland 7; The reaction force that when the hammering operation, produces of hammer body 1 acts on the shock absorber 8 through connector 2, back-up ring 6 like this; Alleviating the back through shock absorber 8 is being transmitted on the piston rod 5; Bounce-back campaign, vibration and the noise of reaction force, hammer body 1 are all significantly subdued; The utility model is reasonable in design, can effectively prolong the working life of hydraulic jack.
From the above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
