Embodiment Construction
[0012] The structure of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] see Figure 1-5 As shown, the handrail protection device on the escalator or moving walk includes a switch 2, which is used to send a signal to stop the escalator or moving walk when the handrail 7 is broken. The switch 2 includes a switch seat 5, The first contact and the second contact that are arranged on the switch base 5, the switch arm 6 that is rotatably arranged on the switch base 5 between the first contact and the second contact, the switch arm 6 and the switch base 5 An elastic member for providing an elastic restoring force of the switch arm 6 is arranged between them, and the conditions for triggering the elevator stop are controlled by the rotation of the switch arm 6. Specifically, the handrail belt 7 has a normal state and a broken belt state. When the handrail belt 7 When in a normal state, the armrest band 7 is pressed against...

The invention discloses a handrail strap protective device on an escalator or a moving sidewalk. When a handrail strap is in a normal state, the handrail strap is pressed at the head of a switch arm, the switch arm is not in contact with a first contact and a second contact, thus ensuring the normal operation of the handrail strap; when the handrail strap is in a broken state, if the broken position of the handrail strap is close to a switch, the switch arm resets elastically, the switch arm is in contact with the first contact, the switch sends a signal to cause the escalator or the moving sidewalk to stop, thus ensuring the safety of passengers; and if the broken position of the handrail strap is far away from the switch, the broken handrail strap can press down the switch arm, so that the switch arm rotates and is in contact with the second contact, and the switch also sends a signal to cause the escalator or the moving sidewalk to stop, thus ensuring the safety of the passengers, and improving the safety performance of the escalator or the moving sidewalk.
Description
technical field [0001] The invention relates to a protection device for handrails on escalators or moving walks. Background technique [0002] During the process of transporting passengers on the escalator or moving walk, the handrail may break. If the escalator or moving walk does not stop in time, it may cause injury to passengers and reduce the safety of the escalator or moving walk. Contents of the invention [0003] The object of the present invention is to provide a handrail protection device which can stop the operation of the escalator or moving walk when the handrail is broken by setting a switch. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a handrail protection device on an escalator or a moving walk, and the handrail protection device includes a signal that can stop the escalator or the moving walk when the handrail is broken. The switch of the running signal, the switch is set in the handrail tensi...
