Abstract

The invention provides an elevator pit box, comprising a top plate, a left side plate, a right side plate, a left bottom plate and a right bottom plate, the left side plate is vertically connected to the left end of the top plate, and the left bottom plate is vertically connected to the bottom end of the left side plate, The right side plate and the left side plate are left and right symmetrical about the central axis of the top plate, and the right bottom plate and the left bottom plate are left and right symmetrical about the central axis of the top plate; There are several screw holes around the installation hole, the inspection socket installation hole and the emergency stop button installation hole. There are cable connector installation seat holes on the left side plate. Have a first fixing screw hole, and have a second fixing screw hole on the right bottom plate. The beneficial effect is that the utility model has a simple overall structure, is easy to assemble, can be installed with an alarm, and ensures safety, and is coated with a protective metal layer on the surface, is not easy to be affected by moisture, and has a long service life.

Description

technical field [0001] The invention belongs to the field of elevator pit inspection box devices, and in particular relates to an elevator pit box. Background technique [0002] The pit inspection box is a device used by maintenance personnel to enter the bottom of the elevator shaft to inspect the elevator. It is usually installed on the side wall of the elevator pit and connected to the elevator control system through a cable connection. When the elevator is inspected, the maintenance Personnel can control the operation and stop of the elevator through the emergency stop button arranged on the box body. The traditional pit inspection box is composed of a separate box body and a cover, which need to be assembled separately, the installation is complicated, and screws need to be fastened in multiple places; the existing pit inspection box does not have an alarm installation hole, and it is difficult to install the alarm , there are potential safety hazards; the surface of t...
