Technical field
The utility model relates to a kind of elevator shock-absorbing device, particularly a kind of damping device of lift machine.
Background technique
In existing elevator, the general elevating movement by hoist machine traction elevator car.In the working procedure of lift machine, particularly draw car and carry out in the process of fast lifting, lift machine often produces vibrations, thus affects elevator traveling comfort.In order to address this problem, now generally at elevator hoisting motor spindle, Rubber shock-absorbing pad or damping spring are installed and carry out damping; But the bearing power of Rubber shock-absorbing pad is more weak, cannot be used for the damping of the larger hoist machine of weight, Applicable scope is less; Damping spring is self meeting to-and-fro motion (beating) when damping, and damping effect is undesirable, and the inefficacy and damping spring gets rusty easily, working life is shorter.And, when the elevator of high speed operation needs to carry out emergency braking, due to the tractive force of the self gravitation of traction sheave on hoist machine and the larger of wire rope, easily cause hoist machine to be tumbled, affect the safety in operation of hoist machine.Therefore, existing damping device also exists the problem that bearing power is more weak, Applicable scope is less, damping effect is undesirable, working life is shorter and hoist machine is easily tumbled.
Model utility content
The purpose of this utility model is, provides a kind of damping device of lift machine.The utility model not only has that bearing power is strong, applied widely, the advantage of good damping effect and long service life, can also prevent hoist machine from tumbling.
The technical solution of the utility model: the damping device of lift machine, comprises base plate, the top of base plate is provided with mounting plate, is provided with some Rubber shock-absorbing pads between base plate and mounting plate; Be provided with telescopic shock absorber between adjacent two pieces of Rubber shock-absorbing pads, outside telescopic shock absorber, be arranged with damping spring; The upper surface of described base plate and the lower surface of mounting plate are equipped with some draw rings, draw ring is connected with extension spring.
In the damping device of aforesaid lift machine, the draw ring on one end connecting bottom board of described extension spring, the draw ring on the other end connection plate of extension spring.
In the damping device of aforesaid lift machine, the left side of described mounting plate, right side and rear side are provided with some fasteners, and be provided with buffer layer between the top of fastener and mounting plate, the top of fastener is provided with limiting board, and fastener is bolted base plate.
In the damping device of aforesaid lift machine, described base plate and mounting plate are all also provided with some location pieces, and location piece is all positioned at the outside of Rubber shock-absorbing pad, and described telescopic shock absorber is vibration damper conventional in automobile suspension system.
Compared with prior art, the utility model improves the structure of lift machine damping device.The utility model installs hoist machine by mounting plate, arranges Rubber shock-absorbing pad, telescopic shock absorber and damping spring to realize the damping of lift machine between mounting plate and base plate; Play main cushioning effect by damping spring, and suppress beating of damping spring by telescopic shock absorber, improve damping effect; And the stroke of the piston rod of telescopic shock absorber has upper and lower bound, spring-compressed can be prevented excessive, mounting plate can also be held by piston rod, prevent hoist machine from tumbling; Play auxiliary damping by Rubber shock-absorbing pad, and protect damping spring, prevent damping spring to get rusty inefficacy, improve working life; Played the effect of auxiliary damping by the buffer layer on fastener, improve damping effect further.When hoist machine is tumbled, the extension spring tension mounting plate of side of tumbling, plays the effect preventing from tumbling; Meanwhile, the limiting board on fastener can limit the highest shock position of mounting plate, prevents hoist machine from tumbling.Therefore, the utility model not only has that bearing power is strong, applied widely, the advantage of good damping effect and long service life, can also prevent hoist machine from tumbling.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.The damping device of lift machine, form as shown in Figure 1, 2, comprise base plate 1, the top of base plate 1 is provided with mounting plate 2, is provided with some Rubber shock-absorbing pads 3 between base plate 1 and mounting plate 2; Be provided with telescopic shock absorber 4 between adjacent two pieces of Rubber shock-absorbing pads 3, telescopic shock absorber 4 is vibration damper conventional in automobile suspension system, is arranged with damping spring 5 outside telescopic shock absorber 4; The upper surface of described base plate 1 and the lower surface of mounting plate 2 are equipped with some draw rings 6, and draw ring 6 is connected with extension spring 7, the position at mounting plate 2 four angles is strained in extension spring 7.
Draw ring 6 on one end connecting bottom board 1 of described extension spring 7, the draw ring 6 on the other end connection plate 2 of extension spring 7; The left side of described mounting plate 2, right side and rear side are provided with some fasteners 8, every side is provided with 2 fasteners 8, buffer layer 9 is provided with between the top of fastener 8 and mounting plate 2, buffer layer 9 can carry out auxiliary damping when mounting plate 2 upwards shakes, the top of fastener 8 is provided with limiting board 10, limiting board 10 can prevent mounting plate 2 from tumbling, and fastener 8 is bolted base plate 1; Described base plate 1 and mounting plate 2 are all also provided with some location pieces 11, and location piece 11 is all positioned at the outside of Rubber shock-absorbing pad 3, and the position of restriction Rubber shock-absorbing pad 3, prevents Rubber shock-absorbing pad 3 in shock absorbing process from offseting.
During installation, the bottom of lift machine is installed and is connected on mounting plate 2.During work, hoist machine vibrations drive mounting plate 2 vertical tremor, and damping spring 5, Rubber shock-absorbing pad 3, buffer layer 9 and telescopic shock absorber 4 carry out damping work simultaneously.Telescopic shock absorber 4 adopts vibration damper conventional in automobile suspension system, during work, piston rod in telescopic shock absorber 4 drives piston repeatedly to move up and down in work cylinder barrel, the fluid in work cylinder barrel is made just to flow in another chamber from a chamber through different holes repeatedly, by the friction between hole wall and fluid and fluid intermolecular interior friction, damping force is formed to vibrations, make vibration energy be converted into fluid heat energy, carry out damping, suppress beating of damping spring 5.And the stroke of the piston rod of telescopic shock absorber 4 has upper and lower bound: the upper limit is that piston is moved upward to work cylinder barrel top, work cylinder barrel top is blocked in the continuation of piston limited piston bar and is moved; Lower limit is that piston is moved downward to bottom work cylinder barrel, blocks piston limited piston bar and continue to move down bottom work cylinder barrel.Spring-compressed can be prevented so excessive, mounting plate can also be held by piston rod, prevent hoist machine from tumbling.
When hoist machine is tumbled, hoist machine can drive mounting plate 2 to tumble, and draw ring 6 on mounting plate is strained in the extension spring 7 of side of tumbling, thus tension mounting plate 2, play the effect preventing from tumbling; Meanwhile, the limiting board 10 on fastener 8 can limit the highest shock position of mounting plate 2, prevents mounting plate 2 and hoist machine from tumbling further.
