Abstract
The utility model relates to a buffer-stop for elevators, which comprises metal connecting plates which are fixedly installed at the bottom of an elevator and a counterweight car. The buffer-stop for elevators is characterized in that polyurethane bumping blocks are fixedly installed on the metal connecting plates. The utility model uses polyurethane as the bumping blocks. Because a plurality of micro pores filled with air exist in the polyurethane combined chemically by macromolecules, each micro pore is equal to a small air sac. When the elevator is impinged, huge kinetic energy is absorbed by the air sac air bags; therefore, better damping effect is generated. The utility model has the advantages of long service life and no need of maintenance.
Description
The utility model is a kind of safety device of elevator, particularly a kind of buffer of elevator.
The energy disperser that is applied to elevator now has only spring and two kinds of structures of hydraulic pressure, and the absorption Impact energy of spring bumper is poor, and bounce is big, fractures easily.Though and the water bumper good absorbing effect, complex structure costs an arm and a leg, and needs periodical maintenance, and safeguard and maintenance all very inconvenient.
The purpose of this utility model provides a kind of later-model buffer of elevator, and it can overcome existing shortcoming in the prior art, has buffering effect and long service life preferably, does not need periodical maintenance simultaneously.
The purpose of this utility model is achieved in that it includes the metallic interconnect of the bottom that is fixedly mounted on elevator and counterweight cab, is characterized in that being installed with on the metallic interconnect polyurethane buffering piece.
The utility model adopts polyurethane as bump rubber, owing to have the numerous micropore that is full of air in the polyurethane body that Polymer chemical combination forms, and each micropore just equals a ballonet, when it was subjected to clashing into, bump rubber produced the change of contracting, and huge kinetic energy is absorbed by air bag, being converted to potential energy discharges with its exhaust, so produce buffering effect preferably, and long service life, need not maintenance.
Below 1 in conjunction with the embodiments and accompanying drawing the utility model is described in further detail.
Fig. 1 is a structure cutaway view of the present utility model.
Fig. 2 is the upward view of Fig. 1.
As shown in the figure, the 1st, advance to belong to connecting panel, have connecting bore around it, be fixed on screw on the channel-section steel of elevator and counterweight cab bottom, polyurethane buffering piece 2 is fixedly mounted on the metallic interconnect, and metallic interconnect is provided with skeleton 3, is used for and being fastenedly connected of polyurethane buffering piece.
