Abstract
Counterweight buffer board, it is related to elevator technology field, metal connecting plate including being fixedly mounted on counterweight bottom, buffering channel-section steel is fixedly connected with the metal connecting plate, some buffer stoppers are embedded with the middle part of the metal connecting plate, the second buffer board is fixed with the top of the buffer stopper, the metal connecting plate is parallel with second buffer board and is in close contact.The utility model make it that can enters row buffering to counterweight to it when to focusing on up-downgoing per se with buffer unit.
Description
Technical field
Elevator technology field is the utility model is related to, more particularly, to counterweight buffer board.
Background technology
It is generally necessary to Buffer for elevator does not stop at the bottom as safety device for elevator when car or to focusing on
In the case of when pouring melt pit, the device, which has using about below 1G average retardation rate, stops the performance of elevator as ensuring to pacify
Full shock-absorbing capacity, it is also necessary to which buffer prevents the acceleration more than 2.5G to be continued above 0.04 second.That is, it needs to buffer has
Remain stable and prevent the excessive excellent shock-absorbing capacity of acceleration.
The buffer applied to elevator is usually two kinds of structures of spring and hydraulic pressure now, the absorption impact energy of spring buffer
Amount is poor, and bounce is big, easily snaps off；Although and hydraulic bjuffer good absorbing effect, it is complicated, it is expensive, it is necessary to
Periodic maintenance, and safeguard and overhaul and be all inconvenient.But counterweight is but not provided with buffer in itself, it is impossible to counterweight vibrations or
Person buffers when whereabouts.
Presently disclosed number is that a kind of Buffer for elevator is disclosed in CN202186808U open file, including fixed peace
Mounted in elevator and the metal connecting plate of counterweight cage bottom, the first buffer board is fixedly connected with the metal connecting plate, it is described
Buffer stopper is vertically and fixedly provided with the middle part of first buffer board, the second buffer board, first buffering are fixed with the top of the buffer stopper
Plate is parallel with the second buffer board.
Above-mentioned prior art is also provided in shaft bottom, can only enter row buffering to counterweight when counterweight is fallen down, and
Bradyseism can not be carried out when counterweight up-downgoing vibrations or other modes shake.
The content of the invention
The utility model purpose is so that counterweight per se with buffer unit, the can pair when to focusing on up-downgoing
It enters row buffering.
Above-mentioned technical purpose of the present utility model technical scheme is that：Counterweight buffer board, including
It is fixedly mounted on the metal connecting plate of counterweight bottom, it is characterised in that buffering channel-section steel is fixedly connected with the metal connecting plate,
Some buffer stoppers are embedded with the middle part of the metal connecting plate, the second buffer board, the metal are fixed with the top of the buffer stopper
Connecting plate is parallel with second buffer board and is in close contact.
It can match somebody with somebody when giving counterweight one buffering when ensuring to focusing on compensated chain stress, and counterweight is fallen
Close the additional buffering of buffer.
Preferably, the metal connecting plate has hard metal layer and a soft metal layer, second buffer board with it is described soft
Metal level is in close contact.Absorption affinity between the two is a soft contact, and there is one preferably to be delayed when being given a shock
Punching.
Preferably, the buffering channel-section steel has substrate, the length of the substrate is more than the length of the metal connecting plate.
Preferably, the width of the substrate is less than the width of the metal connecting plate.
The structural strength that aforesaid substrate can preferably realize the buffering of counterweight and be connected with the length and width configuration of metal connecting plate.
Preferably, the channel-section steel inner surface that buffers is into a cambered surface.Strengthen the structural strength of buffering channel-section steel.
Advantageous effects of the present utility model are：
The whole buffering of counterweight and compensated chain is realized, can be delayed when up-downgoing and when dropping to hole bottom
Punching so that the service life increase of counterweight, buffered the vibrations of counterweight and compensated chain in hoistway, ensure that in whole hoistway
It is quiet and steady.
Brief description of the drawings
Fig. 1 is top view of the present utility model；
Fig. 2 is sectional view of the present utility model；
In fig. 1 and 2,1- metals connecting plate, 2- buffering channel-section steels, 3- buffer stoppers, the buffer boards of 4- second.
Embodiment
Counterweight buffer board as depicted in figs. 1 and 2, including the metal connecting plate 1 of counterweight bottom is fixedly mounted on, metal connects
Buffering channel-section steel 2 is welded with fishplate bar 1, the middle part of metal connecting plate 1 is embedded to be welded with four block buffering blocks 3, and the fixation of the top of buffer stopper 3 is set
There is the second buffer board 4, the second buffer board 4 is formed in one with buffer stopper 3, and metal connecting plate 1 and the second buffer board 4 are parallel and tight
Contiguity is touched, and is welded to connect between the buffer board 4 of metal connecting plate 1 and second.Metal connecting plate 1 has hard metal layer and soft metal
Layer, the second buffer board 4 are in close contact with soft metal layer.Buffering channel-section steel 2 has substrate, and the length of substrate is more than metal connecting plate 1
Length.The width of substrate is less than the width of metal connecting plate 1.
The inner surface of channel-section steel 2 is buffered into a cambered surface.
Bolt bore can also be opened up on metal connecting plate 1 and on substrate, setting bolt is realized on metal connecting plate 1 and base
The bolt connection of plate.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art can make various corresponding changes and deformation, but these phases according to the utility model
The change and deformation answered should all belong to the protection domain of the utility model claims.
