Abstract
The utility model discloses a damping unit for an elevator. The damping unit comprises a base (5) which is provided with a hollow pillar, the body of the hollow pillar is provided with a line trough, and a closed coil (4) is installed inside the line trough; a permanent magnet (2) is installed inside the hollow pillar, and the upper end of the permanent magnet (2) is fixed below a top board (1); and in addition, a supporting spring (6) used for supporting the top board (1) is sleeved outside the body of the hollow pillar. According to the damping unit, the closed coil and the permanent magnet are installed between the base and the top board, force which constantly resists movement of the top board relative to the base is provided through the lenz law, and the force constantly changes along with the speed of the relative movement of the top board. When the damping unit is applied to an elevator car, buffering power which is matched in real time can be provided for passengers inside the elevator car, buffering effects of the damping unit is much higher than that of spring damping, and comfort of the passengers is greatly improved.
Description
Technical field
The utility model relates to a kind of elevator, particularly the damping shock absorption unit used of a kind of elevator.
Background technique
Elevator cab is the directly elevator components of contact of passenger, in order to improve passenger's ride quality, usually can use control device to make the running speed of lift machine control to such an extent that comparatively relax, to suppress the overweight and weightless discomfort of bringing to the passenger.But because elevator floor generally only has 3 to 4 meters, deceleration and accelerating travel are shorter, and be overweight and weightless very difficult effectively controlled.Therefore at present, a lot of elevator manufacturer all arranges the buffer device such as spring to alleviate overweight and weightless concussion between elevator cab and car underframe, number be the utility model patent of CN 202116141 U as notice of authorization, it discloses a kind of damping frame for elevator car.Comprise car body, limit frame, underframe, damping spring; Described limit frame is arranged in the both sides of car body, and underframe is arranged between the below, dual-side frame of car body, arranges damping spring between car body and underframe.The terraced car dynamic mount that the utility model provides utilizes the limit frame to absorb the vibrations of elevator both sides, and the bottom vibrations are absorbed by the damping spring of bottom, and the vibrations that car is subject to reduce to minimum.Increased the comfort level when taking.But this mode damping effect is regulated and is realized by spring, and the elastic force of spring and spring are compressed or the distance dependent of elongation, in the situation that passengers quantity is different, the compressed degree varies sample of spring causes the effect of damping effectively not bring into play.
The model utility content
The purpose of this utility model is, the damping shock absorption unit that provides a kind of elevator to use.The utility model can be used for elevator cab, can play cushioning effect in elevator cab, promotes comfort of passenger thereby greatly improve.
The technical solution of the utility model: the damping shock absorption unit that a kind of elevator is used is characterized in: comprise base, base is provided with hollow posts, also is provided with wire casing on the cylinder of hollow posts, is provided with closing coil in wire casing; Be provided with permanent magnet in hollow posts, the upper end of permanent magnet is fixed under top board; And hollow cylinder is arranged with the supported spring for roof supporting outward.When top board was subject to moving upward, the damping shock absorption unit provided the power of stubbornly resisting upwards, and this power of stubbornly resisting is relevant with the speed of related movement of top board, and the speed of related movement of top board is larger, and the power of stubbornly resisting is larger; When top board was subject to moving downward, the damping shock absorption unit provided the downward power of stubbornly resisting, and this power of stubbornly resisting is relevant with the speed of related movement of top board, and the speed of related movement of top board is larger, and the power of stubbornly resisting is larger; Make the motion of top board be in all the time the damped motion state.Its basic principle is: when moving near closing coil due to permanent magnet, under the effect of Lenz's law, closing coil can produce a magnetic field of resisting all the time the permanent magnet motion, and this magnetic field is relevant to the movement velocity of permanent magnet, speed is faster, and magnetic intensity is larger.
In the damping shock absorption unit that above-mentioned elevator is used, described top board has spring seat, is used for the fixed support spring.
Compared with prior art, the utility model utilizes Lenz's theorem by closing coil and permanent magnet are set between a base and top board, provides a moment to resist the power of the relative base motion of top board, and this power changes constantly with the speed of related movement of top board.The utility model is applied to elevator cab the cushion effect of real-time matching can be provided for the passenger in elevator cab, also spring shock absorption is high a lot of relatively for its cushioning effect, and passenger's comfort level also greatly is improved.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-top board, 2-permanent magnet, 3-spring seat, 4-closing coil, 5-base, 6-supported spring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The damping shock absorption unit that a kind of elevator is used as shown in Figure 1, comprises base 5, and base 5 is provided with hollow posts, also is provided with wire casing on the cylinder of hollow posts, is provided with closing coil 4 in wire casing; Be provided with permanent magnet 2 in hollow posts, the upper end of permanent magnet 2 is fixed on top board 1 time; And hollow cylinder is arranged with the supported spring 6 for roof supporting 1 outward.Described top board 1 has spring seat 3.
Working principle of the present utility model: during use, base of the present utility model is fixed on the bottom surface of elevator cab, then laying floor on top board of the present utility model can evenly arrange a plurality of damping shock absorptions of the present utility model unit between elevator cab bottom surface and floor.At this moment, when being subject to moving upward on the floor, damping shock absorption of the present utility model unit provides the power of stubbornly resisting upwards, and this power of stubbornly resisting is relevant with the speed of related movement of top board, and the speed of related movement on floor is larger, and the power of stubbornly resisting is larger; When the floor was subject to moving downward, the damping shock absorption unit provided the downward power of stubbornly resisting, and this power of stubbornly resisting is relevant with the speed of related movement of top board, and the speed of related movement on floor is larger, and the power of stubbornly resisting is larger; Make the motion on floor be in all the time the damped motion state.Thereby the vibrations of the passenger on the floor have been weakened.
Claims (2)
1. damping shock absorption unit that elevator is used, it is characterized in that: comprise base (5), base (5) is provided with hollow posts, also is provided with wire casing on the cylinder of hollow posts, is provided with closing coil (4) in wire casing; Be provided with permanent magnet (2) in hollow posts, the upper end of permanent magnet (2) is fixed under top board (1); And hollow cylinder is arranged with outward for the supported spring of roof supporting (1) (6).
