Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention 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 pressing to produce braking force.Ratchet 10 arranges mounting hole, and brake disc 20 and mounting hole coordinate to install and be connected.In the axial direction, arrange brake facing between brake disc 20 and mounting hole, brake facing brake disc 20 of both having got along well bonds, and ratchet 10 of also getting along well bonds.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 then adopt Q235-A.In radial directions, arrange friction lining between brake disc 20 and mounting hole, friction lining brake disc 20 of both having got along well bonds, and ratchet 10 of also getting along well, braking platen 30 bond.One side end face of ratchet 10 is close to each other with braking platen 30, opposite side end face is provided with sealed card stop ring sheet 110; Sealed card stop ring sheet 110 connects with brake disc 20, and the brake facing be arranged between ratchet 10 and brake disc 20 is engaged, prevent moving axially of brake facing, because sealed card stop ring sheet 110 achieves the sealing completely to the gap between ratchet 10 and brake disc 20, therefore it can also prevent outside lubricating oil engaging friction sheet.
Brake disc 20 comprises disk body, the radially-outer surface of disk body is provided with bulge loop, bulge loop and disk body forming station scalariform, two side end faces of bulge loop all arrange friction lining, two side end faces of bulge loop are also provided with backing block, and backing block prevents friction lining and brake disc from producing relative sliding.In the present embodiment, friction lining is made up of two semi-rings, and it is between the two across backing block.Ratchet 10 arranges mounting hole, and the inwall of mounting hole is step-like, comprises first step and second step, and mounting hole is corresponding with brake disc 20.First step comprises the first radial face and the first axial vane surface, and second step comprises the second radial face and the second axial vane surface.Disk body and the first radial face offset, and arrange first brake sheet 410 between disk body and the first radial face; First side end face and first axial vane surface of bulge loop offset, and it arranges the first friction lining 210 between the two; Outer diameter face and second radial face of bulge loop offset, and it arranges the second brake facing 420 between the two; Braking platen 30 is arranged on the second axial vane surface and with the second side end face of bulge loop and offsets, and it arranges the second friction lining 220 between the two.Braking platen 30 is connected with ratchet 10 by pretension bolt 310, pretension bolt 310 is arranged with disk spring 320.Several alignment pin is also provided with between braking platen 30 and ratchet 10.
The Novel slide device integral installation of additional brake is prepared, after adjusting braking force, then by 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 runs, ladder sprocket wheel 50 drives brake disc 20 synchronous axial system, simultaneously under the effect of static friction force, and braking platen 30 and ratchet 10 and brake disc 20 synchronous axial system.Therefore when escalator normal (moving sidewalk) works, Novel slide device entirety and ladder sprocket wheel 50 synchronous axial system of additional brake.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 gear brake) 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, speed discrepancy is produced between braking platen 30 and brake disc 20, 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 embodiment of the present invention or principle are described.
1, the Novel slide device of additional brake independent that is relative and additional brake designs, exactly carriage is assembled separately, and after adjusting braking force, then its integral installation gone to ladder sprocket wheel 50, the difficulty of processing effectively reducing part improves efficiency of assembling simultaneously.
2, when the additional brake of escalator (moving sidewalk) is braked, ratchet carries out promptly 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, brake facing can effectively buffer-braking time ratchet 10 radial impact that is subject to, avoid ratchet 10 and with brake disc 20 radial fit place because impacting the burr produced, extend the 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 the burr harmful to friction lining when brake facing and brake disc 20, ratchet 10 relative sliding, can not be produced.
4, the both sides of the bulge loop of brake disc 20 arrange friction lining and backing block, and friction lining is made up of two semi-rings, and it is provided with backing block between the two.Backing block prevents friction lining and brake disc from producing relative sliding, improves brake efficiency.
5, in the Novel slide device of the present embodiment additional brake, have employed double-brake sheet and the combination of two friction lining, effectively improve brake efficiency.
6, in the Novel slide device of the present embodiment additional brake, have employed disk spring 320 to carry out pretension, disk spring 320 will brake platen 30 to ratchet 10 pressing.Disk spring 320 position that takes up room is little, makes the Novel slide device structure of whole additional brake simpler, compact.Simultaneously, in the measurement of braking force, just indirectly can be determined the size of braking force by the amount of compression measuring disk spring 320, when engineering site is safeguarded, the adjustment that step just can carry out braking force can not be dismantled, effectively improve the efficiency of engineering maintenance guarantee.
7, positioned by several alignment pin between brake disc 20 and ratchet 10, meanwhile, alignment pin is circumferentially square to be evenly arranged, to reduce ratchet 10, to brake the shearing force to the pretension bolt 310 of fixing disk spring 320 when platen 30 rotates together.
8, sealed card stop ring sheet 110 is adopted to engage the brake facing be arranged between ratchet 10 and brake disc 20, cover completely because space between sealed card stop ring sheet 110 pairs of ratchets 10 and brake disc 20 achieves and seal, 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 only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
