The purpose of the embodiment of body, it is not intended that in limitation the application.
Referring to shown in Fig. 1, Fig. 2, Fig. 8, a kind of additional brake of staircase, comprising:
The ratchet 1 being rotatably installed on staircase and girder 5；
The braking sprocket wheel 4 for rotating with ratchet 1 and being matched with step chain 6；
It is rotatably arranged on staircase and girder 5 and cooperates the pawl 2 to brake staircase with ratchet 1；
The driving mechanism that staircase control system signal is received to drive pawl 2 to act.
Staircase described herein includes escalator and moving sidewalk.
Additional brake provided by the present application is mounted on the tilting section or horizontal segment of staircase and girder 5, is preferably mounted at and is helped
On the tilting section of terraced truss 5, additional brake is not directly placed on the main driving of staircase, reduces the intensity requirement to main driving,
Special reinforcement is not needed to the staircase and girder 5 of installation position simultaneously.
Step chain 6 is matched with braking sprocket wheel 4, is referred to and is meshed between step chain 6 and braking sprocket wheel 4 and carries out chain biography
Dynamic cooperation, i.e. step chain 6 and braking sprocket wheel 4 move synchronously, one of them stop motion, then another one, that is, stop motion,
Brake force is passed into step chain 6 by braking sprocket wheel 4.
In staircase normal course of operation, step chain 6 drives braking sprocket wheel 4 to rotate, and braking sprocket wheel 4 drives ratchet 1 to rotate,
When needing stop, the rotation of stop ratchet 1 is acted by pawl 2, braking sprocket wheel 4 stops operating with ratchet 1, and then stop step
The stop of staircase is realized in the movement of chain 6.
The Braking of the additional brake is on step chain 6, by the movement of stop step chain 6, in turn
Prevent the operation of staircase.
Referring to shaft 7 shown in Fig. 7, Fig. 9, Figure 11, is fixed on staircase and girder 5, the rotation of ratchet 1 is set in shaft 7.Turn

Friction plate 8 is two panels, is located between interconnecting piece 10 and the first pressing plate 121 and interconnecting piece 10 and second is pressed
Between plate 122, it can guarantee that enough frictional force exports by two sides friction plate 8, improve braking efficiency, guarantee the reliable of braking
Property.
The two sides of pressure spring 125 compress nut 124 and adjacent the first pressing plate 121 or the second pressing plate 122 respectively, by adjusting
Cooperation position of the nut 124 on screw rod 123, the decrement of adjustable pressure spring 125, and then adjust friction plate 8 and adjacent portions
The frictional force of part, namely the size of adjustment brake force.
Pressure spring 125 can be controlled brake force by disc spring, be made additional brake using the disc spring being set on screw rod 123
More compact structure, it is convenient for safeguarding.
First pressing plate 121 and the second pressing plate 122 are annular, and are arranged around terminal pad 11, shown in Figure 10, spiral shell
Bar 123 has more, and more 123 twisted rotary shafts 7 of screw rod are arranged, is combined with pressure spring 125 and nut 124 on every screw rod 123.
First pressing plate 121 or the second pressing plate 122 are equipped with the accommodation groove for accommodating pressure spring 125, are also arranged on screw rod 123
Seat 126 is compressed, the axial side and nut 124 for compressing seat 126 offset, and the other side offsets with pressure spring 125.
First pressing plate 121 and the second pressing plate 122 are equipped with the mounting hole of perforation, and screw rod 123 is threaded through in mounting hole, compresses
The axial side of seat 126, which is equipped with, extends into axially extending section of mounting hole, and mounting hole position corresponding with axially extending section has
The limited step matched with axially extending section prevents pressure spring 125 to be overly compressed by limited step.
Referring to shown in Figure 11, Figure 12, the surface and corresponding side of the first pressing plate 121 and the second pressing plate 122 away from interconnecting piece 10
The surface flush of terminal pad 11.
Braking sprocket wheel 4 is fixedly connected with terminal pad 11, and the two rotates synchronously, and referring to shown in Figure 10, Figure 11, brakes sprocket wheel 4
It is detachably connected with terminal pad 11.It is fixedly connected between braking sprocket wheel 4 and terminal pad 11 by more bolts of annular arrangement, spiral shell
Bolt uses hinged bolts, effectively to transmit brake force.
Referring to shown in Fig. 1, Fig. 3, Fig. 5, disclosed herein as well is a kind of staircase, the additional brake is installed, it is attached
Add brake at least a pair of, each pair of additional brake is arranged along staircase traffic direction, belongs to a pair of additional brake distribution
In the two sides of staircase width direction, the braking sprocket wheel 4 of additional brake is matched with adjacent step chain 6.
The quantity of additional brake determines that additional brake is located at ladder according to the different braking power demand of different hoisting depths
The two sides of grade chain 6, and close on main driving setting.
Driving mechanism can be respectively set in each additional brake, a driving machine can also only be arranged in the ipsilateral of staircase
Structure drives all pawls 2 to move by driving member.Referring to fig. 2, shown in Fig. 4, Fig. 6, staircase in one of the embodiments,
