Abstract

The utility model discloses an elevator cushioning device, comprising a buffer (3) arranged on the pit of a elevator hoistway. The buffer (3) is arranged on the vertical projection of the elevator car. The utility model also comprises a cushion structure which is paved on the pit and arranged around the buffer. A cushion structure is arranged on the pit of the elevator hoistway, and the cushion structure can effectively ensure the safety of the person from slipping down by the mechanical energy absorbed by the cushion structure from the person falling into the hoistway.

Description

A kind of elevator buffer device
Technical field
The utility model relates to a kind of elevator buffer device, is specifically related to the elevator buffer device of being made up of cushion rubber and energy disperser.
Background technology
The degenerate accident of hoistway of some personnel can take place in the use of elevator unavoidably, and this degeneration generally can be divided into two kinds of situations: a kind of is layer door degeneration from elevator, and at this moment because layer is opened, elevator can not move; Another is the car degeneration from elevator, may degenerate from the top of car or from the gate of elevator, and at this moment elevator can move.During pit in the people degenerates elevator hoistways, parts in the pit and floor all can cause serious injury personnel.
Now the shock absorber in the elevator hoistways perhaps is called as energy disperser, is cylindrical rigid construction, and its effect is to prevent lift car or counterweight is out of control car or counterweight is carried out buffer protection when rushing at pit and pit collision on the ground.But, can't protect for the personnel of the degeneration hoistway of slipping.
Japan publication spy drives the shock absorber that 2007-197138 discloses a kind of elevator; when car is out of control when rushing at pit; car be contained in a protrusion member on the flat board and bump against; the size of this flat board is suitable with the area of pit; then; the buffer body that flat board moves downward two sides about compression plays buffer action, with the safety of protection car.The purpose of this shock absorber is in order to reduce the degree of depth of pit; The same with existing elevator buffer device, can't protect the personnel that from hoistway, degenerate.
Summary of the invention
For solving the problem that prior art exists, the utility model provides a kind of elevator buffer device that can effectively protect degeneration personnel from hoistway.
The utility model adopts following technical scheme to realize above-mentioned purpose: a kind of elevator buffer device, comprise the energy disperser that is arranged on the elevator hoistways pit, and energy disperser is positioned on the vertical projection of car; Also be provided with pad body structure, this pad body structure is laid on the pit, and be positioned at energy disperser around.
Above-mentioned pad body structure comprises cushion, following cushion and plurality of support columns, and some pillar stiffeners are arranged between cushion and the following cushion.
Be provided with step switch in the above-mentioned pad body structure, when the pad body structure pressurized, the closing of contact of step switch, elevator is out of service.
A contact of above-mentioned step switch is arranged on the lower surface of cushion, and another contact is arranged on down the upper surface of cushion.
In the above-mentioned elevator buffer device, also be provided with another energy disperser, this energy disperser is positioned on the vertical projection of counterweight.
The lateral circle surface of above-mentioned upper and lower cushion is provided with reinforced rib.
Pad body structure is set on elevator pit, utilizes pad body structure to absorb the mechanical energy of degeneration personnel in the hoistway, provide safety guard-safeguard to the degeneration personnel that slip effectively.In addition, also be provided with step switch in the pad body structure, when the people degenerated hoistway, the closing of contact of step switch was cut off the power supply of elevator, thereby made elevator at once out of service, had further strengthened the safety guard-safeguard to the degeneration personnel that slip.

The specific embodiment
The utility model comprises energy disperser 3, the pad body structure that is arranged on the elevator hoistways pit, wherein pad body structure be positioned at energy disperser around, thereby when the unexpected degeneration of car, pad body structure can not influence the buffer action of energy disperser to car.Pad body structure comprise down cushion 2 ', go up cushion 2, between two block buffering pads, also be provided with plurality of support columns 1.In addition, for further strengthening the protection of the utility model to the degeneration personnel, also be provided with step switch between upper and lower cushion, when the people degenerated, step switch 4 started, and closes the power supply of elevator, makes elevator out of service.
To whether comprise that step switch respectively for an embodiment, further specifies the utility model to the utility model below:
Embodiment 1
As shown in Figure 1 to Figure 3, energy disperser 3 of the present utility model is arranged on the pit of elevator hoistways, and is positioned on the vertical projection of car, and energy disperser 3 can be an accumulating type, also can be energy-dissipating type.The bottom face 31 of the following cushion 2 of pad body structure ' alignment energy disperser 3, last cushion 2 are then a little more than the top end face 32 of energy disperser 3.Plurality of support columns 1 is arranged between the upper and lower cushion.In the present embodiment, pillar stiffener 1 has 12, is distributing eight around pad body structure, is distributing four in pad body structure.Shown in Fig. 2,3, last cushion 2 comprises cushion rubber face 21, and is arranged in the reinforced rib 22 of cushion rubber face 21; Last cushion 2, down cushion 2 ' and the material of reinforced rib 22 can be foam, or rubber, or Nomex, or nylon.Following cushion 2 ' identical with the structure and the material of last cushion 2, comprise cushion rubber face 21 ', and be arranged in cushion rubber face 21 ' reinforced rib 22 '.
Embodiment 2
Extremely shown in Figure 6 as Fig. 4, the structure of present embodiment is similar to Example 1, different places are: added step switch 4 between upper and lower cushion, a contact 41 of step switch 4 is arranged on the lower surface of cushion, and another contact 42 is arranged on down the upper surface of cushion.Added another energy disperser 5 in addition on the vertical projection of Elevator weight sensor, energy disperser 5 structures are between upper and lower cushion.
When the people degenerates, the contact 41 and contact 42 closures of step switch 4, the power supply of cut-out elevator, elevator is at once out of service.
