Abstract
The utility model relates to a dish spring damping rubber buffer, which is used for the buffer devices of door base type cranes and large hoisting machines. The defect of the shock absorbing performance reduction caused by the oil leak in work of the original technology of a butterfly spring hydraulic buffer can be overcome. An original disk spring group is changed into a combination formed by a cylindrical and sulfiding disk spring of damping rubber and the apposition of the disk spring, the same magnitude of force can be borne, and the sufficient displacement can be provided to realize good damping property. The utility model has the advantages of simple structure, high capability, the damping effect of bidirectional damping rubber, long service life, easy maintenance, etc. The utility model can bear bidirectional carrying capacity of pull and press.
Description
The utility model is mainly used in the dish spring damping rubber buffer of gantry crane tooth bar luffing buffering.
The dish spring hydraulic bjuffer of being formed by cylinder barrel, guide sleeve, piston rod, dish spring group, piston, cylinder pedestal, piston end cap, gland nut etc. that in known high pedestal jib crane (being designated hereinafter simply as a machine) tooth bar jib lubbing mechanism, adopts, owing to adopt the buffer of oil pressure structure more easily to produce oil leakage phenomenon at work, thereby make damping property descend greatly, also shorten working life thereupon.
To be that design is a kind of adopt dish spring group that dish spring and sulfuration damping rubber dish spring combine as elastic element to the purpose of this utility model, it is big to have bearing capacity, simple in structure, can bear the tension compression bidirectional load force, and two-way all have a damping rubber cushioning effect, and the dish spring damping rubber buffer of advantage such as the long service life maintaining is easy.
Technical solution of the present utility model is: a kind of dish spring damping rubber buffer that is used for high pedestal jib crane and large scale hoisting machinery damping device, it is made of cylinder barrel (1), guide sleeve (2), piston rod (3), dish spring group (4), piston (5), piston (6), cylinder bottom seat (7), piston end cap (8), gland nut (9) etc., it is characterized in that: dish spring group (4) is to be combined by sulfuration damping rubber dish spring (49) and the involutory form of dish spring (50).
Sulfuration damping rubber dish spring of the present utility model (49) respectively on dish spring bi-side conical surface body (51) and following conical surface body (52) sulfuration damping rubber that it is become is cylindrical.Thereby realize that the dish spring bears outer load force, the sulfuration damping rubber plays the damping buffering effect.
Because the utility model adopts sulfuration damping rubber dish spring (49) and the involutory formation dish of dish spring (50) spring group, is bearing the size of same power, guarantee enough displacement amounts realizing good shock absorbing characteristics, and have the advantages that bearing capacity is big, size is little.Thereby overcome the shortcoming that known dish spring hydraulic bjuffer easily produces leakage of oil and decreases damping performance.
Routine accompanying drawing has been described an embodiment of the present utility model down.
Accompanying drawing is a general assembly sectional drawing of the present utility model.
With reference to accompanying drawing, dish spring damping rubber buffer is that piston rod (3) is housed in cylinder barrel (1), dish spring group (4), dish spring group (4) is to adopt involutory form to place by sulfuration damping rubber dish spring (49) and dish spring (50), piston (5), piston (6), gland nut (9), cylinder barrel (1) one end is by cylinder bottom seat (7) sealing, and same bolt (10) is fastening, there is a circular groove (12) that has Sealing (11) in the outer garden of cylinder bottom seat (7), the guide pin bushing (14) by jump ring (13) location is equipped with in interior garden, and the interior garden of cylinder bottom seat (7) and end cap (15) constitute the circular groove (17) that has a Sealing (16).The other end of cylinder barrel (1) is by piston end cap (8) sealing, there is the circular groove (19) that has a Sealing (18) in the outer garden of piston end cap (8), interior garden is by the guide sleeve (21) of jump ring (20) location, the interior garden of piston end cap (8) and end cap (22) constitute the circular groove (24) that has a Sealing (23), piston rod (3) includes the piston head (25) of a convex shoulder, pass the guide sleeve (21) of piston end cap (8), the outer garden of bar (26) of piston rod (3) has the circular groove (28) of a Sealing (27), guide sleeve (2) is screwed into the threaded end (30) of piston rod (3) by screw thread (29), and the guide sleeve (13) by piston base (7), clamping piston (6) is locking by nut (31).Locking nut (9) has precompressed transformation amount for dish spring group (4) by piston (6).The casing wall (32) of cylinder barrel (1), the hole (33) of the piston head (25) of piston rod (3) and bar (26), piston (5) constitutes a cavity (35) with the shoulder (34) of piston end cap (8) and guide sleeve (21).The shoulder (36) of the casing wall (32) of cylinder barrel (1), the bar (26) of piston (3), guide sleeve (2), cylinder bottom seat (7), the hole (37) of piston (6) constitute cavity (38).The casing wall (32) of cylinder barrel (1), the bar (26) of piston (3), piston (5), piston (6) constitute cavity (39).Tapped hole (40), (41) are arranged at cylinder barrel (1) top, and two bolts (42), (43) are housed, and a pad (44), (45) sealing are respectively arranged.The engaging lug (46) of piston rod (3) links to each other with the external structure central shaft.Bolt hole (47) on the flange of cylinder barrel (1), cylinder bottom seat (7) upper bolt hole (48) links to each other with door machine rack structure and fixing by bolt (10).
When outside the utility model is subjected to, loading pulling force, its process acts on the engaging lug (46) of piston rod (3) for the external structure central shaft, the guide sleeve (2) that threaded end (30) by piston rod (3) is screwed into, compression piston (6), dish spring group (4), piston (5) are pressed to piston end cap (8) and are passed to cylinder barrel (1), up to the rack structure that links to each other with cylinder barrel (1).
The utility model is owing to guarantee the outer diameter D 1 of guide sleeve (2) and outer diameter D 2 consistent size of the piston head (25) of piston rod (3): D1=D2 on when design structure, the volume V2 that the volume V1 that the space of cavity (38) increases and the space of cavity (35) increase, by cavity (39) compression space volume V3, hole (33), (37) make the unlikely formation vacuum of compression volume, because D1=D2, so V3=V1+V2, thereby dish spring damping rubber cushioning effect when realizing tensile load.
Outside the utility model is subjected to during load pressure, its process is: central shaft is by engaging lug (46), piston head (25) compression piston (5) by piston rod (3), dish spring group (4), piston (6), arrive cylinder barrel (1) by gland nut (9), up to the rack structure that links to each other with cylinder barrel, the volume V2 ' of the volume V1 ' that cavity (35) space increases and the increase of the space of cavity (38) is by cavity (39) compression space volume V3 ', and hole (33), (37) are used for making the unlikely formation vacuum of compression volume.Thereby dish spring damping rubber cushioning effect when realizing pressure load.
