Embodiment Construction
[0009] The structure of the present invention will be further described below in conjunction with the accompanying drawings.
[0010] see figure 1 and figure 2 As shown, a safety device for an escalator or moving walkway includes a motor flywheel 1, a motor brake chassis 2 arranged below the motor flywheel 1, a lock 3, a safety switch 4 arranged on the motor brake chassis 2, and a motor The rotation of the flywheel 1 can provide the power of the escalator or the moving walkway, and the braking of the motor flywheel 1 can stop the escalator or the moving walkway. The corresponding position is provided with a second lock hole 6, and the safety device has a working state and a non-working state. When the safety device is in a working state, such as figure 2 As shown, the locking piece 3 is inserted in the first locking hole 5 and the second locking hole 6, and by braking the motor flywheel 1, the escalator or moving walkway can be prevented from starting, and the locking piec...

The invention discloses a safety device of an escalator or a moving walkway. The safety device comprises a motor flywheel, an electric brake chassis arranged below the motor flywheel, a locking piece and a safety switch which is arranged on the electric brake chassis, wherein the motor flywheel is provided with a first locking hole; and a position, which corresponds to the first locking hole, on the electric brake chassis is provided with a second locking hole. When the safety device is in the working state, the locking piece is inserted into the first locking hole and the second locking hole, the motor flywheel can be braked, the escalator or the moving walkway can be prevented from being started, the locking piece triggers the safety switch and the power supply of the escalator or the moving walkway can be cut off, so that safety hidden trouble caused when the power supply of the escalator or the moving walkway is forgotten to be cut off carelessly is eliminated and the safety of maintenance personnel is fully guaranteed; and when the safety device is in the non-working state, the locking piece is separated from the first locking hole, the second locking hole and the safety switch, and the escalator or the moving walkway can be restarted.
Description
technical field [0001] The invention relates to a safety device for an escalator or a moving walkway. Background technique [0002] Escalators or moving walks are widely used in shopping malls, airports and railway stations. Escalators or moving walks need to be maintained regularly. During the maintenance period, the escalators or moving walks need to be powered off to protect maintenance personnel. Personal safety, but sometimes carelessness may lead to forgetting to turn off the power supply of the escalator or moving walk, and there are potential safety hazards, so the safety device created by the present invention was born. Contents of the invention [0003] The purpose of the present invention is to provide a safety device on an escalator or moving walk that can fully ensure the safety of maintenance personnel. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a safety device for an escalator or moving walk, c...
