[0016] based on Figure 1 to Figure 4 The escalator 1 of 1st Embodiment is demonstrated.
[0017] First, based on figure 1 , figure 2 The structure of the escalator 1 is demonstrated.
[0018] The escalator 1 has a truss 51 which is installed astride between the upper floor and the lower floor of the installation structure on which the escalator 1 is installed. A pair of railings 52 and 52 are provided on the left and right sides above the truss 51 , and handrails 53 are respectively hung around the railing 52 .
[0019] A main rotation shaft 54 , a pair of left and right sprockets 55 a and 55 b connected to the main rotation shaft 54 , and a drive device 56 including a drive motor, a reduction gear, and the like are arranged on the upper layer side in the truss 51 .
[0020] A main rotation shaft 57 and a pair of left and right sprockets 58 and 58 connected to the main rotation shaft 57 are arranged on the lower layer side in the truss 51 . A pair of left and right ...

[0049] Next, based on Figure 5 The escalator 1 of 2nd Embodiment is demonstrated.
[0050] This embodiment differs from the first embodiment in the structure of the auxiliary brake device 10 .
[0051] like Figure 5 As shown, in the present embodiment, the stopper 49 that supports the claw portion 30 of the brake claw 26 from below is supported by a support rod 70 that protrudes and contracts from the base 20 freely. The support rod 70 is always urged upward by the coil-shaped spring 72, and the stopper 49 always urges the base of the claw portion 30 upward.
[0052] When inactive, the support portion 36 supports the actuation portion 32 of the brake pawl 26 , and the pawl portion 30 is fixed at the retracted position in the downward direction against the biasing force of the spring 72 .
[0053] During the operation, the disconnection of the driving force transmission chain 68 is detected, and the support portion 36 moves from the left side of the groove 34 to the right ...

Abstract
PROBLEM TO BE SOLVED: To provide a passenger conveyor that can quickly stop the rotation of a sprocket thanks to the fact that a brake pawl securely engages a tooth portion of the sprocket. SOLUTION: The passenger conveyor has: the brake pawl 26 prepared on a part of a truss 51 located below a brake plate 12, the brake pawl 26 moving by turning between an engagement position where the brake pawl 26 engages the tooth portion 28 and a retreated position where the brake pawl 26 retreats from the engagement position; and a stopper 49 which supports the brake pawl 26 from its underneath to prevent a tip of the brake pawl 26 from being repelled from the tooth portion 28 upon rising of the tip of the brake pawl 26 from the retreat position to the engagement position.

Description
[0001] This application is based on Japanese Patent Application No. 2010-184736 (filing date: 8 / 20 / 2010), and enjoys the priority of this application. This application contains the entire contents of this application by reference to this application. technical field [0002] Embodiments of the invention relate to a passenger conveyor. Background technique [0003] In a passenger conveyor, for example, an escalator, an endless conveyor chain that connects steps and moves cyclically is moved by a sprocket that is rotated by a driving force transmission chain. Therefore, in the escalator, it is assumed that the auxiliary braking device is attached when the driving force transmission chain is disconnected. [0004] In this auxiliary brake device, when it is detected that the driving force transmission chain is disconnected, the brake pawl is moved, and the distal end of the moved brake pawl meshes with the tooth portion of the sprocket. As a result, the rotation of the sprocke...
