Machine-room-less elevator maintenance device

Abstract

The invention relates to an elevator maintenance device, belonging to the technical field of elevators, and in particular relates to a machine-room-less elevator maintenance device. The machine-room-less elevator maintenance device is provided with an upper girder component and a maintenance box fixedly installed together with the upper girder component; the upper girder component is connected with a guide rail by a bolt; the maintenance box is internally connected with a pin shaft passing through the maintenance box; a safety switch which is in contact with the pin shaft and can be triggered during maintenance is arranged above one end of the pin shaft; a pin shaft locating plate used for locating the pin shaft is fixedly connected with the left side of the pin shaft; a fixed clamping groove used for preventing the pin shaft from accidentally deviating is formed in the locating plate. The machine-room-less elevator maintenance device has the advantages that the device is capable of fixing in multiple ways, and is simple in structure, convenient to install and locate and safe in elevator locking; the maintenance device is installed under the upper girder component of a lift car, the cost is reduced, and the safety of maintenance is effectively improved.

Description

Technical field: [0001] The invention relates to an elevator maintenance device, belonging to the technical field of elevators, in particular to a machine room-less elevator maintenance device. Background technique: [0002] When the elevator adopts machine room-less, the current technology is usually to add a bracket on the car frame, a slidable bolt rod is arranged on the bracket, a fixed plate is installed on the guide rail, and the bolt hole is opened on the fixed plate. When the elevator needs to be repaired or During maintenance, in order to avoid the accidental movement of the elevator, the staff needs to insert the latch rod into the latch hole to fix the car and the guide rail. There is no relatively safe fixing device on the latch rod. injury to staff. Invention content: [0003] The purpose of the present invention is to provide a machine room-less elevator maintenance device which enables the car to be positioned reliably during inspection or maintenance, and ...
