Boots are arranged in layer door guide rail and move up and down in layer door guide rail, arrange the door crosspiece below lower floor's door-plate between the guide rails；
Pulley yoke and the pulley being arranged on pulley yoke, wirerope one end are fixedly attached to upper strata door-plate, and the other end bypasses cunning
Wheel is connected to hall door and hangs on wall；
The rubber blanket and the weightening pad for balance for buffering is provided with lower floor's door.
In above-mentioned technical proposal, the hall door hangs the both sides that wall is separately fixed at lower floor's door-plate.
In above-mentioned technical proposal, the hall door is hung.
In above-mentioned technical proposal, one end of wirerope is fixedly attached to upper strata door-plate, and the other end bypasses pulley and is connected to the Room
On the pull bar of gantry crane wall.
In above-mentioned technical proposal, the wirerope is not contacted with Room gate guide shoe and layer door guide rail.
In above-mentioned technical proposal, the inner surface setting of lower floor's door-plate has weightening pad.
In above-mentioned technical proposal, the outer surface lower end of lower floor's door-plate increases rubber blanket.
In above-mentioned technical proposal, the rubber blanket includes several, is evenly distributed on the same horizontal line of lower floor's door-plate
On.
Compared with prior art, the invention has the beneficial effects as follows：This programme simple structure, it is easy to operate, can be effective
Prevent wirerope from occurring the fracture of one or multiply, steel wire rope in running and beat torsion, rope stretch or diameter reduction etc.
Problem.If avoiding steel wire rope by jam between guide rail and the gap for leading boots, there is also layer door and cannot open or cannot close
The problem closed, so that the safety coefficient of layer door is reduced, it is easier to potential safety hazard occur.

Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, described pulley is fixed on pulley yoke, one end of steel wire rope is fixed on the door-plate of upper strata, steel wire
Rope is fixed on hall door arm through the pulley other end, carrys out key-course door by the door handle pulled on dynamic on door-plate during use
Open and close, due to the guide effect of layer door guide rail so that layer door is moved on layer door guide rail using Room gate guide shoe, due to weight
The effect of power so that layer door maintains the original state after pulling, pulls door handle that layer door is closed after using and finishing again.
Most of sundry elevators are when civil engineering is built as pit is than shallower, after layer door is fully opened to layer door lower floor's door
Plate distance is relatively limited, as long as thus ensure that the layer door of lower end can extend downwardly into the upper of lower floor's door-plate completely in design
End face can be all turned on state with exterior decoration planes align can both ensure layer door.As the case may be referring to sometimes for guarantor
The door enabling of card layer is highly larger, but in the case that pit depth is relatively limited again, the height of upper strata door-plate can be set by we
The height more than lower floor's door-plate of meter, and in order to keep both weight balancings, can increase in the inner surface of lower floor's door-plate
Weightening pad is as shown in Figure 2.Most sundry elevators are highly larger in order to allow layer door to open the door, but the again relatively more limited feelings of low hole depth
Under condition, the lower surface hypotelorism of the position of lower end door crosspiece away from lower floor's door-plate, through prolonged use, sundry elevator is in handling
When goods, lower floor's door-plate upper surface also suffers from the extruding of goods, so that the steel wire rope of upper end is also subjected to larger drawing
Power and there is loosening phenomenon, after causing every sublevel door to be opened, the layer door board lower surface of hypomere will be occurred with door crosspiece
Collision phenomenon, it is if long-time severe crash can also cause layer door directly to spin off from layer door guide rail, more so as to occur
Potential safety hazard.In view of under these unstable factors I in this improvement lower floor's door-plate lower surface two ends increase
Rubber blanket so that good cushioning effect can be played when there is collision, the dynamics of collision is reduced, be the safety of layer door
With the protecting function for serving.
As shown in Figure 3, Figure 4, hall door arm is increased in current improvement secondly, the effect of the device is made from upper end
The steel wire rope that pulley is drawn directly is not connected with lower floor door-plate, but hall door arm is fixed on the both sides of lower floor's door-plate, then by
It is fixed on the steel wire rope that the pull bar that hall door hung on wall bypasses pulley with early stage to be connected, advantage of this is that makes layer door directly not hold
By the pulling force of steel wire rope, and steel wire rope not directly with Room gate guide shoe or layer door guide rail contact, prevent the switching process in layer door
In, the steel wire rope contact with Room gate guide shoe and increasing friction force with layer door guide rail or steel wire rope so that one occurs in steel wire rope
Or torsion is played in multiply fracture, steel wire rope, the problems such as rope stretch or diameter reduce.If steel wire rope by jam guide rail with
Lead between the gap of boots, there is also the problem that layer door cannot be opened or cannot be closed, so that the safety coefficient drop of layer door
It is low, it is easier to potential safety hazard occur.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
