The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.
The Novel slide device of additional brake as shown in Figures 1 to 4, comprises ratchet 10, brake disc 20 and braking platen 30, and brake disc 20 is arranged between ratchet 10 and braking platen 20, braking platen 30 by brake disc 20 with ratchet 10 pressings with generation braking force.Ratchet 10 arranges mounting hole, and brake disc 20 coordinates to install with mounting hole and is connected.In the axial direction, between brake disc 20 and mounting hole, brake facing is set, the brake facing brake disc 20 of both having got along well is bonding, and the ratchet 10 of also getting along well is bonding.Ratchet 10 carries out radial location by brake facing and brake disc 20, and in the present embodiment, brake facing adopts aluminum alloy materials, and brake disc 20 and ratchet 10 adopt Q235-A.In the radial direction, between brake disc 20 and mounting hole, friction lining is set, the friction lining brake disc 20 of both having got along well is bonding, and the ratchet 10 of also getting along well, braking platen 30 are bonding.One side end face of ratchet 10 is mutually close with braking platen 30, is provided with sealed card stop ring sheet 110 on opposite side end face; Sealed card stop ring sheet 110 joins with brake disc 20, and the brake facing being arranged between ratchet 10 and brake disc 20 is locked, prevent moving axially of brake facing, because sealed card stop ring sheet 110 has been realized the sealing completely to the gap between ratchet 10 and brake disc 20, therefore it can also prevent outside lubricating oil engaging friction sheet.
The Novel slide device integral installation of additional brake is prepared, after adjusting braking force, then the non-drive side that the Novel slide device integral installation of additional brake is assembled in top sprocket wheel.Brake disc 20 is mutually permanently connected by bolt and ladder sprocket wheel 50.
When escalator (moving sidewalk) normally moves, ladder sprocket wheel 50 drives brake discs 20 synchronously to rotate, simultaneously under the effect of static friction force, brakes platen 30 and ratchet 10 and synchronizes rotation with brake disc 20.Therefore when escalator normal (moving sidewalk) work, the Novel slide device of additional brake is whole synchronizes rotation with ladder sprocket wheel 50.When the additional brake of escalator (moving sidewalk) is braked, braking force contrary with ratchet 10 hand of rotation (be generally ratchet tighten up make ratchet braking) acts on ratchet 10, ratchet 10 stops operating gradually under the effect of this braking force, because ratchet 10 is fixedly connected with braking platen 30, so time ratchet 10, between braking platen 30 and brake disc 20, produce speed discrepancy, static friction force between them becomes the force of sliding friction that brake disc 20 is stopped operating, ladder sprocket wheel 50 slowly stops operating under the effect of this force of sliding friction, complete braking procedure.
Below the advantage of the utility model embodiment or principle are described.
1, the Novel slide device of additional brake independent relative and additional brake designs, exactly carriage is assembled separately, and after adjusting braking force, then its integral installation is gone to ladder sprocket wheel 50, the difficulty of processing that effectively reduces part has improved efficiency of assembling simultaneously.
2, when the additional brake of escalator (moving sidewalk) is braked, ratchet is firmly grasped ratchet 10, and ratchet 10 is subject to huge radial impact power.And between brake disc 20 and ratchet 10, adopt brake facing to carry out radial location, the brake facing radial impact that effectively ratchet 10 is subject to during buffer-braking, avoid ratchet 10 and with the burr of brake disc 20 radial fit places because impact producing, extended life-span of Novel slide device.
3, simultaneously, because brake facing is all not identical with the material of brake disc 20, ratchet 10.Therefore can not produce the burr harmful to friction lining when brake facing and brake disc 20, ratchet 10 relative sliding.
4, the both sides of the bulge loop of brake disc 20 arrange friction lining and backing block, and friction lining is comprised of two semi-rings, and it is provided with backing block between the two.Backing block prevents that friction lining and brake disc from producing relative sliding, improves brake efficiency.
5, in the Novel slide device of the present embodiment additional brake, adopt double-brake sheet and the combination of two friction lining, effectively improved brake efficiency.
6, in the Novel slide device of the present embodiment additional brake, adopted disk spring 320 to carry out pretension, disk spring 320 will be braked platen 30 to ratchet 10 pressings.Disk spring 320 position that takes up room is little, makes the Novel slide device structure of whole additional brake simpler, compact.Simultaneously, aspect braking force measurement, can just the size of braking force can be determined indirectly by measuring the amount of compression of disk spring 320, when engineering site is safeguarded, can not dismantle step and just can carry out the adjustment of braking force, effectively improve the efficiency of engineering maintenance guarantee.
7, between brake disc 20 and ratchet 10, by several alignment pin, position, meanwhile, alignment pin is evenly arranged along circumference is square, with reduce ratchet 10, braking platen 30 while rotating together to the fixing shearing force of the pretension bolt 310 of disk spring 320.
8, adopt 110 pairs of brake facings that are arranged between ratchet 10 and brake disc 20 of sealed card stop ring sheet to lock, owing to having realized and cover completely and seal in space between 110 pairs of ratchets 10 of sealed card stop ring sheet and brake disc 20, sealed card stop ring sheet 110 can prevent moving axially of brake facing on the one hand, sealed card stop ring sheet 110 can prevent external lubrication oil engaging friction sheet on the other hand, reduces friction efficiency.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
