Embodiment Construction

[0011] Such as figure 1 and figure 2 Shown: an escalator rear plate anti-lifting safety device related to the present invention, including a rear plate, a baffle plate 2 is arranged under the rear plate 1, a guide rod 3 is fixedly connected to the baffle plate 2, and the middle end of the guide rod 3 is clamped Connect a pressing plate 4, below the pressing plate 4, there is a pop-up baffle plate 2 and a spring assembly 5 of the pressing plate 4 that are sleeved on the guide bar 3, and a safety switch 6 is mechanically connected to the side of the pressing plate 4, and the safety switch 6 is directly connected to the control power supply 7 of the escalator. The spring assembly 5 is in a compressed state when the back plate 1 is covered, and is in an open state when the back plate 1 is lifted. The elasticity of the spring can be utilized to control the safety switch 6 to ensure safety. The pressure plate 4 and the guide rod 3 are fixedly connected by the fixing bolt 8, which ...

Abstract

The invention relates to an anti-lifting safety device for a rear plate of an escalator, and belongs to the field of elevator safety. The anti-lifting safety device comprises the rear plate. A baffle is arranged below the rear plate. A guide rod is fixedly connected to the baffle. A pressing plate is connected with the middle end of the guide rod in a clamping manner. A spring assembly which is arranged on the guide rod in a sleeving manner and used for bouncing the baffle and the pressing plate is arranged below the pressing plate. A safety switch is mechanically connected to the side face of the pressing plate and is directly connected with an escalator control power supply. During normal installation, the rear plate can press the baffle when closed, the baffle transmits downward pressure to the guide rod, the guide rod drives the safety switch connected with the pressing plate so that the safety switch can be switched on, and the escalator normally runs; and once the rear plate is lifted up, the pressing plate can be lifted up under the influence of elasticity of the spring assembly, the safety switch is mechanically switched off, and accidental situations can be effectively prevented. The anti-lifting safety device has the beneficial effect that a purely-electric type rear plate anti-lifting safety device which is generally used and does not meet the national standard requirement is replaced. The acting force is exerted through springs so that switch contacts can be forcedly and mechanically disconnected. The anti-lifting safety device is small and exquisite in structure, convenient to install and adjust and capable of effectively preventing the accidental situations.

Description

Technical field: [0001] The invention relates to an anti-lifting safety device for the rear plate of an escalator, which belongs to the field of elevator safety. Background technique: [0002] "5.12.1.2.2 Safety Switch" in "GB16899-2011 Safety Code for Installation of Escalators and Moving Walks" stipulates that "the action of the safety switch should make the contact point mechanically disconnected, and even the two contacts should be welded together. Mechanical disconnection of the ground.” Nowadays, the anti-lifting safety device of the rear plate of the escalator generally uses the safety switch contact to directly contact the escalator rear plate. The action of the switch contact depends on the automatic reset of the switch itself, and no mandatory mechanical structure is used. . This commonly used device does not meet the requirements of the new national standard. Invention content: [0003] In order to solve the above technical problems, the present invention rela...
