Abstract
The utility model relates to a cushioning device of the hydraulic cylinder of hydraulic hammer class equipment such as a hydraulic pile driver and a hydraulic rammer compactor. The cushioning device comprises a hammer body (11), a connector (12), a cushioning piece (13), a gland (14) and a hydraulic cylinder (15), etc., wherein, the connector (12) is connected with the hammer body (11) through a pin shaft (22) or a flanged disc; the gland (14) is fixed at the end of the connector (12) provided with a connecting hole (19); the piston rod (18) of the hydraulic cylinder (15) is provided with a retainer ring (16); the cushioning piece (13) is arranged between the retainer ring (16) arranged on the piston rod (18) and the gland (14), and is positioned inside the connecting hole (19) of the connector (12); moreover, the cushioning piece (13) is made of rubber, nylon or other elastic materials. Because the utility model is provided with the cushioning piece which has cushioning effect, the utility model has the characteristics of compact structure, remarkable reduction in the impact and noise generated during hammering and the prolonged service life of the hydraulic cylinder, etc.
Description
One, technical field:
The utility model relates to a kind of hydraulic pressure cylinder cushion that is used for hydraulic hammer kind equipments such as hydraulic pile driver, hydraulic pressure beater, hydraulic hammer kind equipments such as specifically a kind of hydraulic pile driver, hydraulic pressure beater reduce noise and alleviate the suffered impact of hydraulic cylinder when hammering, prolong the hydraulic cylinder cylinder cushion device in application life.
Two, background technology:
Hydraulic cylinder one end of hydraulic hammer kind equipments such as present domestic hydraulic pile driver, hydraulic pressure beater is installed on the frame, the other end connects with hammer body with flange or hinge pin, its shortcoming is that hammer body is when impacting, impact with bounce-back and act directly on the hydraulic cylinder piston rod, the complete machine vibrations are big, noise is big, and hydraulic cylinder is short application life.
Three, summary of the invention:
The purpose of this utility model is that the hydraulic cylinder for hydraulic hammer kind equipments such as hydraulic pile driver, hydraulic pressure beaters provides a kind of buffer, its compact conformation, and impact and noise in the time of can significantly reducing hammering prolong application life of hydraulic cylinder.
For achieving the above object, the technical scheme that the present invention takes is: include hammer body, coupling, bolster, gland, hydraulic cylinder etc.One end of coupling is provided with connection holes, the other end that bolster is installed and connects with hammer body by bearing pin or flange, gland is fixed on coupling and is provided with on the end of connection holes, its end that stretches out hydraulic cylinder of the piston rod of hydraulic cylinder is provided with back-up ring, and bolster is contained between back-up ring on the piston rod of hydraulic cylinder and the gland and packs in the connection holes of coupling by gland.
The material of bolster is rubber or nylon or other elastomeric material.
Because the utility model is provided with bolster, the reaction force that hammer body produces when the hammering operation acts on the bolster by coupling, back-up ring, be transmitted on the piston rod after bolster is alleviated, bounce-back campaign, vibration and the noise of reaction force, hammer body all obtained cutting down significantly again.When hammer body promoted, piston rod shrank, and by back-up ring compression bolster, promoted hammer body by gland, coupling again, the moment impact in the time of can reducing the lifting conversion.Therefore, the utlity model has compact conformation, impact and noise in the time of can significantly reducing hammering, the characteristics such as application life that prolong hydraulic cylinder.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
Five, the specific embodiment
Accompanying drawing is an embodiment of the present utility model, includes hammer body (11), coupling (12), bolster (13), gland (14), hydraulic cylinder (15) etc.One end of coupling (12) is provided with the installation bolster
(13) connection holes (19), the other end connect with hammer body (11) by bearing pin (22) or flange, and present embodiment is to connect with hammer body (11) by bearing pin (22); Gland (14) is fixed on coupling (12) and is provided with on the end of connection holes (19), frame (21) hinge-coupled of one end of hydraulic cylinder (15) and hydraulic hammer kind equipment, its end that stretches out hydraulic cylinder (12) of the piston rod (18) of hydraulic cylinder (15) is provided with back-up ring (16), and bolster (13) is contained between the back-up ring (16) and gland (14) on the piston rod (18), and pack in the connection holes (19) of coupling (12) by gland (14).
In order to prolong the application life of bolster (13), can between bolster (13) and gland (14), packing ring (17) be set.
Bolster (13) is the product or the composite member of rubber or nylon or other elastomeric material.Present embodiment is a rubber part.
The reaction force that hammer body (11) produces when impact or tamping operation acts on the bolster (13) by coupling (12), back-up ring (16), be transmitted on the piston rod (18) after bolster (13) is alleviated, bounce-back campaign, vibration and the noise of reaction force, hammer body (11) all obtained cutting down significantly again.When hammer body (11) promoted, piston rod (18) shrank, and by back-up ring (16) compression bolster (13), promoted hammer body (11) by gland (14), coupling (12) again, the moment impact in the time of can reducing the lifting conversion.Therefore, the utlity model has compact conformation, impact and noise in the time of can significantly reducing hammering, the characteristics such as application life that prolong hydraulic cylinder.
Claims (2)
1. cylinder cushion device, include hammer body (11), coupling (12), gland (14), hydraulic cylinder (15), its feature also includes bolster (13), one end of coupling (12) is provided with the connection holes (19) that bolster (13) is installed, the other end by bearing pin (22)/or flange connect with hammer body (11), gland (14) is fixed on coupling (12) and is provided with on the end of connection holes (19), its end that stretches out hydraulic cylinder (15) of the piston rod (18) of hydraulic cylinder (15) is provided with back-up ring (16), and bolster (13) is contained between the back-up ring (16) and gland (14) on the piston rod (18) of hydraulic cylinder (15), and pack in the connection holes (19) of coupling (12) by gland (14).
