Description
Technical Field
The utility model relates to an elevator technical field especially relates to a damping device at bottom of high-speed elevator sedan-chair.
Background
The car is a box-shaped space used by elevators to carry and transport people and materials. The elevator car is generally composed of main components such as a car bottom, a car wall, a car roof, a car door and the like, and is a car body component for carrying passengers, goods and other loads. The faster the elevator runs, the larger the vibration amplitude is when the elevator runs and levels, and the more easily the riding comfort of passengers in the elevator car is influenced, so how to reasonably arrange the damping device in the elevator structure is very important.
At present, the damping effect of the car bottom of the high-speed elevator produced by each elevator manufacturer is generally not ideal. Most manufacturers only use rubber shock absorption or only use springs for shock absorption. And the installation mode of spring shock absorption is adopted, so that the later-stage replacement difficulty is high, and the installation and maintenance are not easy.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems existing in the prior art and providing a damping device at the bottom of a high-speed elevator car.
The technical scheme is as follows: the utility model provides a damping device at bottom of high-speed elevator sedan-chair, includes at the bottom of the elevator sedan-chair and at the bottom of the bracket of elevator sedan-chair, there is a damping device at the bottom of the elevator sedan-chair and between the bracket of elevator sedan-chair bottom through the bolted lock, damping device includes the screw rod and follows the coated damping spring of screw rod length direction, screw rod length direction's both ends all are provided with a yielding rubber, the yielding rubber is cylindric setting, damping spring is located in the middle of two yielding rubbers.
Preferably, the top of the damping device is locked with an upper fixing base plate on the elevator car bottom through bolts.
Preferably, the bottom of the damping device is locked with a lower fixing base plate on the elevator car bottom bracket through bolts.
Preferably, every four damping devices of the elevator car bottom are arranged in one group, and the elevator car bottom is provided with a plurality of groups of damping devices.
Preferably, the straight line of the length direction of the screw is parallel to the straight line of the height direction of the elevator car bottom.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. the utility model discloses a match at the bottom of the elevator sedan-chair, damping device and elevator sedan-chair bottom bracket, damping device installs at the bottom of the elevator sedan-chair in the middle of with elevator sedan-chair bottom bracket, damping spring and yielding rubber among the damping device pass through screw rod realization integral structure, make damping spring and yielding rubber carry out the shock attenuation to the bottom of the elevator sedan-chair simultaneously, improve elevator absorbing efficiency, this structure also is convenient for install and dismantle the change.

in the figure: 1. an elevator car bottom; 2. a damping device; 21. a damping spring; 22. damping rubber; 23. a screw; 3. an elevator car bottom bracket; 4. fixing a base plate; 5. a lower fixed base plate; 6. and (4) bolts.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1 to 2, a high-speed elevator car bottom damping device comprises an elevator car bottom 1 and an elevator car bottom bracket 3, wherein a damping device 2 is locked between the elevator car bottom 1 and the elevator car bottom bracket 3 through a bolt 6, and the damping device 2 is fixed with the elevator car bottom 1 and the elevator car bottom bracket 3 through the bolt 6, so that the damping device 2 can most effectively damp the elevator car bottom 1, and the damping efficiency is improved; damping device 2 includes screw rod 23 and follows the coated damping spring 21 of screw rod 23 length direction, the both ends of screw rod 23 length direction all are provided with a damping rubber 22, damping rubber 22 is cylindric setting, damping spring 21 is located in the middle of two damping rubber 22, makes damping rubber 22 and damping spring 21 integration, and when the elevator vibrations, damping spring 21 and damping rubber 22 homoenergetic can effectually be cushioned, and bolt 6 lock attaches fixedly also be convenient for subsequent installation and dismantlement change.
The top of the damping device 2 is locked with an upper fixing backing plate 4 on the elevator car bottom 1 through a bolt 6, so that the damping device 2 and the elevator car bottom 1 are completely fixed.
The bottom of the damping device 2 is locked with a lower fixing base plate 5 on the elevator car bottom bracket 3 through a bolt 6, so that the damping device 2 and the elevator car bottom bracket 3 are completely fixed, and the damping effect is ensured.
Every four damping device 2 of elevator sedan-chair bottom 1 are a set of, just elevator sedan-chair bottom 1 is provided with a plurality of groups damping device 2, improves damping device 2 and carries out absorbing work efficiency.
The straight line of the screw 23 in the length direction is parallel to the straight line of the elevator car bottom 1 in the height direction.
The utility model discloses a theory of operation: through set up damping device 2 between elevator sedan-chair bottom 1 and elevator sedan-chair bottom bracket 3, through the both ends installation yielding rubber 22 at damping spring 21 improve the damped efficiency of elevator sedan-chair bottom 1, damping spring 21 and yielding rubber 22's simple installation simultaneously, the subsequent dismantlement of being convenient for is changed.
