Upper layer side at truss 12 is provided with Machine Room 20, is provided with as motor 22, the speed reduction gearing 24 of the drive source of escalator 10 and the driving steamboat 26 that is arranged on the outgoing side of speed reduction gearing 24 in these 20 inside, Machine Room.In addition, be provided with the step chains 28 of ring-type for a plurality of steps 14 are moved, 20 inside are provided with step wheels 30 in the Machine Room in order to drive this step chains 28.On the other hand, also be provided with step wheels 34 in 32 inside, Machine Room of lower layer side, set up above-mentioned step chains 28 between this step wheels 30 and step wheels 34.
Be provided with coaxially with step wheels 30 and drive bull wheel 36, set up driving chain 38 between driving bull wheel 36 and driving steamboat 26.In the situation that this driving chain 38 has occured to cut off etc. is abnormal, this situation detected and emergency braking device 40 that the rotation of step wheels 30 is stopped, be arranged on 20 inside, Machine Room of upper layer side.For this emergency braking device 40 in following detailed description.
(2) structure of emergency braking device 40
Then, according to Fig. 2 ~ Fig. 4, the structure of emergency braking device 40 is described.
As shown in Figure 2, as described above, be provided with motor 22, speed reduction gearing 24 in 20 inside, Machine Room of upper layer side, be equipped with on speed reduction gearing 24 and drive steamboat 26.Be provided with coaxially with step wheels 30 and drive bull wheel 36 and ratchet 42.
As shown in Figure 2, in the framework 44 of the truss 12 of the Machine Room 20 that consists of upper layer side, be provided with ratchet beam 46 on the left and right directions on Machine Room 20.This ratchet beam 46 is securely fixed on framework 44.
As shown in Figure 3, be provided with freely connection shaft 48 along 46 rotations of ratchet beam.In the suspention of the left side of this connection shaft 48, ratchet bar 50 is arranged, this ratchet bar 50 rotates centered by connection shaft 48, its front end and ratchet 42 engagements.
As shown in Figure 3, in the suspention of the right side of connection shaft 48, brake shoe bar 52 is arranged, be provided with pressing component (brake shoe) 54 in the bottom of this brake shoe bar 52.Pressing component 54 puts on driving chain 38, and has coupling plate 56.This coupling plate 56 is that as shown in Figure 4, its left part bends upward, and rotates via pin 58 bottom that is suspended in freely brake shoe bar 52 along the long rectangular sheet material of the fore-and-aft direction of driving chain 38.Be provided with rectangular-shaped slide plate 60 below coupling plate 56.Be provided with groove 62 on below this slide plate 60 on fore-and-aft direction, as shown in Figure 4, except the part of this groove 62, the following mode with contact of slide plate 60 puts on driving chain 38.As the material of this slide plate 60, be for example rubber or synthetic resin.
As shown in Figure 4, oil cover 64 is installed on coupling plate 56.This oil cover 64 is bent into anti-L word shape, and top 66 of oil cover 64 is fixed on coupling plate 56, and the side plate 68 that bends is positioned at the outside of driving chain 38.This side plate 68 is not arranged on the inboard of Machine Room 20, and is arranged on the outside (building side).In the inboard of side plate 68, be fixed with tabular oil suction part 70 by screw 72.The length of the fore-and-aft direction of oil cover 64, all long than slide plate 60 in front and back, in addition, side plate 68 extensions are set to than the contact surface between slide plate 60 and driving chain 38 more on the lower.Material as oil suction part 70 is paper, cloth etc.
(3) action of emergency braking device 40
Operating state to emergency braking device 40 describes.
When driving chain 38 cut off for a certain reason or extends, pressing component 54 moved downwards, and meanwhile brake shoe bar 52 rotates (with reference to Fig. 2).When brake shoe bar 52 rotated, ratchet bar 50 rotated similarly via connection shaft 48, and the front end of ratchet bar 50 and ratchet 42 engagements stop the rotation of step wheels 30, escalator 10 emergent stoppings.Thus, can guarantee the user's of escalator 10 safety.
(4) effect
According to above-mentioned embodiment, when driving chain 38 moves, cover top, the outside of driving chains 38 by oil cover 64, therefore can prevent from the oil that splashes from driving chain 38 from especially can preventing the oil that splashes to the building side from truss 12.In addition, side plate 68 extends and is set to than the contact surface between slide plate 60 and driving chain 38 more on the lower, so can prevent splashing of the oil that splashes from this contact portion.Therefore, even the moving velocity of driving chain 38 improves, oil can not splash outside truss 12 yet.
Because the oil that splashes is absorbed by oil suction part 70, so oil can not cover 64 from oil and hangs.Therefore this oil suction part 70 fixes by screw 72, when take off screw 72, oil suction part 70 can be pulled down from oil cover 64, in a certain amount of situation, can be replaced by simply new oil suction part 70 in the amount of the oil that is absorbed by oil suction part 70 in upkeep operation.
Modification
In the above-described embodiment, be illustrated with escalator 10, but also can be applied to moving sidewalk.
Above, an embodiment of the present utility model has been described, but this embodiment is to propose as an example, is not intended to limit scope of invention.These new embodiments can be implemented with other variety of way, can carry out various omissions, displacement and change in the scope that does not break away from inventive concept.These embodiments and distortion thereof are included in scope of invention and purport, and are included in the invention of putting down in writing with the scope of the claims requisition and in the scope that is equal to it.
