Abstract
The utility model relates to an elevator mechanically prevents device down, including connecting rod fixing seat, link mechanism, its characterized in that: the last link mechanism that installs of connecting rod fixing seat, link mechanism links to each other with the steel wire cable, and the action of steel wire cable control link mechanism makes link mechanism be in fold condition to it is down to prevent the electricity to be passed, and resets through automatic the drawing in in of compression spring. Its advantage lies in: 1. It is little to adopt link mechanism occupation space, 2. Steel wire cable fixing base is fixed and is done the position that personnel easily are close to the check man. The console switch mounted position is unrestricted.
Description
Technical field
The utility model belongs to elevator components, is specifically related to a kind of elevator down mechanical holdout device.
Background technology
During overhauling elevator, overhauling elevator personnel generally will enter the on site maintenance that the top layer of hoistway or pit carry out elevator, and period ensures particularly important to service personnel personal safety.Elevator down mechanical holdout device is elevator pit height not being met to GB/T7588-5.7.3.3 safety requirements, the elevator down mechanical holdout device arranged during maintenance, the safety of protection pit overhaul personnel.
At present, existing elevator down mechanical holdout device structure is comparatively complicated, thus take up room comparatively large, and operating switch installation site is restricted, is not easy to operated by personnel.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of elevator down mechanical holdout device that is less, convenient operation that takes up room, the safety of protection pit overhaul personnel.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of elevator down mechanical holdout device, comprise connecting rod permanent seat, connecting rod mechanism, it is characterized in that: installing connecting rods mechanism on connecting rod permanent seat, connecting rod mechanism is connected with wire digging line, wire digging line control link mechanism action, connecting rod mechanism is made to be in folded state, descending to stop electricity to be passed, and automatically draw reset in by Compress Spring.
Described connecting rod mechanism comprises first connecting rod, second connecting rod and third connecting rod, first connecting rod, second connecting rod, third connecting rod are articulated successively, first connecting rod can move up and down along cage guide direction, during first connecting rod action, connecting rod mechanism is in folded state, now second connecting rod crosses out guide rail, descending to stop electricity to be passed.
Described wire digging line one end is connected with first connecting rod, and the other end is fixed on through wire digging line sleeve pipe and triggers on spanner.
It is provided with wire digging line permanent seat in addition, and wire digging line permanent seat is provided with and triggers spanner snap close.
Described wire digging line permanent seat is fixed on the position that service work personnel are easy to close.
Described connecting rod fixed seating is provided with electrical contact switch in the top position place of first connecting rod.
The utility model compared with prior art has following beneficial effect:
1. adopt connecting rod mechanism to take up room little; 2. wire digging line permanent seat is fixed on the position that service work personnel are easy to close.Operating switch installation site is unrestricted.
