High-sensitivity weight-limit induction passenger elevator with machine room

Abstract

The invention relates to a high-sensitivity weight-limit induction passenger elevator with a machine room. The high-sensitivity weight-limit induction passenger elevator comprises a passenger elevator cage, a bottom arranged below the cage, and a driving device used for driving the cage to move up and down, wherein the bottom comprises a cage support fixedly connected with the cage, a platform arranged above the support, a plurality of vertical buffers arranged between the support and the platform, and a weight-limit induction device arranged below the platform, the weight-limit induction device comprises a magnetic relay for sending an alarm when an elevator overloads and cutting off a door circuit, and a trigger block fixed at the bottom of the platform and positioned on the opposite location of the magnetic relay trigger switch, and the magnetic relay is fixed on the upper end surface of the support. The high-sensitivity weight-limit induction passenger elevator with the machine room has high sensitivity, and is longer in service life since the magnetic relay is adopted.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a high-sensitivity weight-limiting sensor organic room passenger elevator. Background technique [0002] The existing weight-limiting sensing device of the passenger elevator in the organic room triggers the alarm through the spring installed on the bottom of the car, but due to long-term use, the elasticity of the spring will weaken, and the response of the weight-limiting sensing device will become slow, and even the overweight cannot issue an alarm , cannot guarantee the safe operation of the elevator. Contents of the invention [0003] The object of the present invention is to provide a high-sensitivity weight-limiting induction organic room passenger elevator [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a high-sensitivity weight-limiting induction organic room passenger elevator, which includes a passenger elevator ca...
