Abstract
Provided is a high -efficient damping device at bottom of elevator sedan -chair with double shock absorption effect, its characterized in that: including pneumatic cylinder (1), lower bolster (2) is connected to pneumatic cylinder (1) bottom, is provided with piston (3) in pneumatic cylinder (1), be connected with push -and -pull rod (4) on piston (3), the cover is gone up in push -and -pull rod (4) has spring (5), and cover rubber sleeve (6) is gone up in spring (5), spring (5) link to each other with upper padding plate (8) through baffle (7). The utility model discloses install at the bottom of the elevator sedan -chair, set up the pneumatic cylinder between upper and lower backing plate. When the elevator starts, drive piston quick up -and -down motion in the pneumatic cylinder through the push -and -pull rod, the kinetic energy of elevator is fallen in quick consumption, and it is steady to make the elevator start. Additionally, the utility model discloses still set up the spring on the push -and -pull rod, set up the rubber sleeve on the spring, avoided the spring surface to rust, prolonged practical life. When the elevator falls because pneumatic cylinder and spring component double shock absorption, great improvement the security of shock attenuation effect and elevator. (B, )
Description
Technical field
the utility model relates to a kind of shock absorption device, particularly a kind of shock absorption device being arranged on elevator car bottom.
Background technology
in recent years, along with the fast development of elevator industry, people are also more and more higher for the requirement of elevator shock-absorbing effect.Therefore, need that shock absorption device is installed bottom lift car and damping is carried out to elevator.Existing elevator generally adopts rubber shock-absorbing device or spring vibration damper.Adopt the elevator of rubber shock-absorbing device, because rubber is easily torn under heavy lift impacts, and the easy aging cracking of rubber, so damping effect is undesirable, service life is shorter.Adopt the elevator of spring vibration damper, elevator starts not steady, and spring surface gets rusty easily, and service life is shorter.In addition, elevator meet accident fall time, it is comparatively slow that rubber or spring vertical tremor consume elevator kinetic energy, and safety performance is undesirable.Therefore, there is the problem that damping effect is undesirable, startup is steady, service life is shorter, the consumption of elevator kinetic energy is comparatively slow and safety performance is undesirable in existing elevator shock-absorbing device.
Utility model content
the purpose of this utility model is, provides a kind of efficient shock absorption device of elevator car bottom with dual shock absorption effect.The utility model improves shock absorption device, has good damping effect, starts steadily, long service life, the consumption of elevator kinetic energy is fast and safety is high advantage.
the technical solution of the utility model: a kind of efficient shock absorption device of elevator car bottom with dual shock absorption effect, comprises hydraulic actuating cylinder, connect lower bolster bottom hydraulic actuating cylinder, be provided with piston in hydraulic actuating cylinder; Piston is connected with pull bar, and on pull bar, cover has spring, and spring overlaps rubber sleeve; Spring is connected with upper padding plate by baffle plate.
aforesaid have in the efficient shock absorption device of elevator car bottom of dual shock absorption effect, and one end of described spring is fixed on baffle plate, and the other end is fixed on hydraulic actuating cylinder upper surface.
aforesaid have in the efficient shock absorption device of elevator car bottom of dual shock absorption effect, and described baffle plate is connected to pull bar top, and is connected with upper padding plate.
compared with prior art, the utility model is arranged on the bottom of lift car by upper padding plate 8, between upper and lower backing plate, be provided with hydraulic actuating cylinder.When elevator starts, drive piston fast speed up-and-down movement in hydraulic actuating cylinder by pull bar, fast speed consumes the kinetic energy of elevator, and elevator is started steadily.In addition, the utility model is also provided with spring on pull bar, and spring is provided with rubber coating, avoids spring surface to get rusty, extends service life.When used during elevator falling, due to hydraulic actuating cylinder and spring composition dual shock absorption, improve the safety of damping effect and elevator greatly.Therefore the utility model there is good damping effect, start steadily, long service life, the consumption of elevator kinetic energy is fast and safety is high advantage.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-hydraulic actuating cylinder, 2-lower bolster, 3-piston, 4-pull bar, 5-spring, 6-rubber coating, 7-baffle plate, 8-upper padding plate.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.There is the efficient shock absorption device of elevator car bottom of dual shock absorption effect, form as shown in Figure 1, comprise hydraulic actuating cylinder 1, bottom hydraulic actuating cylinder 1, connect lower bolster 2, in hydraulic actuating cylinder 1, be provided with piston 3; Piston 3 is connected with pull bar 4, on pull bar 4, cover has spring 5, spring 5 overlaps rubber sleeve 6; Spring 5 is connected with upper padding plate 8 by baffle plate 7.Be connected with the bottom of lift car by upper padding plate 8.
one end of described spring 5 is fixed on baffle plate 7, and the other end is fixed on hydraulic actuating cylinder 1 upper surface.Described baffle plate 7 is connected to pull bar 4 top, and is connected with upper padding plate 8.
the novel bottom being arranged on lift car by upper padding plate 8 of this use, when elevator startup or when falling, upper padding plate 8 relatively lower bolster 2 moves downward, and drives baffle plate 7 to move downward.Because spring 5 is fixed between baffle plate 7 and hydraulic actuating cylinder 1, therefore when baffle plate 7 moves downward, spring 5 starts compression, consumes elevator kinetic energy.Pull bar 4 promotes downwards along with the motion of baffle plate 7 simultaneously, piston 3 is moved downward, the liquid in compression hydraulic cylinder 1, consumes elevator kinetic energy.Thus the dual shock absorption realized elevator.
