Abstract
The utility model discloses a safety switch device for a building hoist. The safety switch device comprises a switch body arranged on the upper portion inside a cage box, a switch arm controlling the working state of a switch is arranged on the switch body, a slop protrusion is arranged on the inner face of a door of the cage box, when the door of the cage box is closed, the slope protrusion is in contact with the switch arm, the switch is in a power-on state, and when the door of the cage box is not closed, the slope protrusion is arranged above the switch arm, and the switch is in a power-off state. The safety switch device for the building hoist is reasonable in structure, and when the door of the cage box of the hoist is not closed well, a system is powered off within a safe stroke range, a response can be made immediately, and the safety of personnel and cargo in the hoist at high attitudes is guaranteed.
Description
Technical field
The utility model relates to a kind of building hoist safety switching apparatus.
Background technology
Traditional building hoist is used contact switch, cuts off the power supply and closes electricity and have retardance, insensitive, unreliable to the safety of operation.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the elevator cage chamber door is when shutting, and system cut-off in the safety travel scope, can make a response at once, guarantees lifting staff on board and the goods building hoist safety switching apparatus at high-altitude safe.
Technical solution of the present utility model is:
A kind of building hoist safety switching apparatus, it is characterized in that: comprise the switch body that is loaded on cage case internal upper part, the switch arm of dress master cock mode of operation on switch body, at cage chamber door inner face, the slope projection is set, when the cage chamber door is closed, the slope projection contacts with switch arm, switch is in "on" position, and when the cage chamber door is closed, the slope projection is not positioned at the switch arm top, and switch is in off-position.
The utility model is rational in infrastructure, and when the elevator cage chamber door does not shut, system cut-off in the safety travel scope, can make a response at once, guarantees that lifting staff on board and goods are at high-altitude safe.
