Abstract

The invention provides an operation safety device of an elevator. The operation safety device can be simply arranged when an operator descends to an elevator pit. The operation safety device of the elevator comprises a handle part which is composed of a front surface part and a pair of side surface parts, the front surface part extends in the left-right direction of an elevator hall entrance and has the width smaller than the width of the elevator hall entrance in the left-right direction, the side surface parts are arranged at the two end parts of the front surface part, and the hands of an operator can be put on the handle part during operation. The elevator waiting hall entrance and exit extends in the depth direction of the elevator waiting hall entrance and exit; the pair of clamping parts are arranged at opposite positions across the handle part, extend from the two end parts of the handle part to the left and right direction of the entrance and exit of the elevator waiting hall, and can be clamped on a three-face frame arranged at the entrance and exit of the elevator waiting hall; and the base part is at least partially fixed on the elevator waiting hall floor side of the handle part in order to form a gap between the handle part and the elevator waiting hall floor.

Description

technical field [0001] The present invention relates to an operation safety device of an elevator. Background technique [0002] In an elevator installed in a building, for example, an elevator, a car on which a user rides is raised and lowered in a hoistway installed in the building. A machine room is provided in the upper part in the vertical direction of the lift passage, and the machine room is provided with a motor that drives a sling connected to the car. In addition, a balance weight connected to a sling is arranged in the lift passage, and an elevator pit is provided in the lower part in the vertical direction of the lift passage, and a buffer for the car and the balance weight is provided in the lift pit. Furthermore, in the elevator pit, a ladder for allowing an operator to enter and exit the elevator pit is attached to the wall surface. [0003] As for the maintenance work of the elevator, it is necessary to carry out work in many places such as the machine room...
