Embodiment Construction

[0029] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0030] Such as figure 1 , 2 , Shown in 3, a kind of elevator hoistway bottom pit maintenance platform, it comprises:

[0031] A telescopic ladder 1, the top of which is hinged on the wall of the bottom pit 3 near the landing door;

[0032] The bearing part 2, the bearing part 2 is fixed on the wall opposite to the landing door side of the bottom pit 3, after the telescopic ladder 1 is rotated around its hinge point with the wall to a horizontal state and stretched, the telescopic ladder 1 The bottom of the bottom is placed on the carrying part 2 to support the telescopic ladder 1 through the carrying part 2.

[0033] Specifically, the telescopic ladder 1 is normally in a vertical state, and the operator uses the telescopic ladder 1 as a tool for...

Abstract

The invention discloses an elevator shaft pit overhauling platform. The elevator shaft pit overhauling platform comprises an extension ladder and a bearing part, and the top of the extension ladder ishinged to the wall of the side, close to the landing door, of a pit; and the bearing part is fixed to the wall opposite to the side, close to the landing door, of the pit, after the extension ladderrotates to the horizontal state around the hinged point of the extension ladder and the wall and extends, the bottom of the extension ladder is placed on the bearing part so as to support the extension ladder through the bearing part. The ladder can be used as a tool for going in and out of the pit, and can also be used climbing a maintenance ladder, so that an operator can conveniently inspect and maintain parts in the pit.

Description

technical field [0001] The invention relates to an elevator shaft bottom pit maintenance platform. Background technique [0002] It is essential for elevator operators to enter the pit of the elevator shaft for installation, maintenance and inspection, because there are many elevator components in the pit, such as: hall door combination, tensioner, buffer, counterweight, Various electrical switches such as compensation chains, various detection switches, limit limit emergency stops, etc. Secondly, the depth of the pit provides a sufficient safety distance for the car, counterweight and maintenance personnel. [0003] The general pit depth of low-speed elevators is about 1.5 meters, and the depth of high-speed elevators will be even deeper. In order to ensure that the operators can safely enter the bottom pit and avoid injury to the maximum extent during construction, it is necessary to set up climbing ladders. The definition of the traditional ladder: it is fixed on the w...
