Problems solved by technology

[0003] However, there is a potential safety hazard in the maintenance device on the car at present.
Due to insufficient space on the top floor of the elevator and the car, the staff cannot turn around, and maintenance personnel or passengers may accidentally touch the button switch, resulting in changes in the working status of the elevator and even accidents.
There is no protective cover around the button or switch on the surface of the existing maintenance device, and because the changeover switch or emergency stop button of the above structure is adopted, sometimes due to human error or misoperation of the changeover switch, emergency stop button, etc., it is easy to cause safety hazards. accident, the personal safety of elevator maintenance personnel and passengers cannot be guaranteed

Embodiment 1

[0030] Such as figure 1 As shown, the present invention provides an elevator car roof inspection safety protection device, which includes a support rod 12 and a base 1, the support rod 12 is rotatably arranged on the base 1, and the support rod 12 is provided with a contact 5, The base 1 is provided with a contact seat 2;

[0031] Also refer to figure 2 , when the support rod 12 is rotated to the horizontal position, the contact 5 is connected to the contact seat 2, the circuit for controlling the operation of the elevator is connected, and the elevator is in a normal running state; when the support rod 12 is rotated to the vertical position, the contact Point 5 leaves the contact block 2, the circuit controlling the operation of the elevator is disconnected, the brake works, and the elevator is in the maintenance state. When the elevator does not need to be overhauled, the support bar 12 is in the horizontal position, the elevator can run normally, and the up, down and war...

Embodiment 2

[0041]This embodiment provides an elevator car top maintenance safety protection device, the technical solution of which is the same as that of Embodiment 1, the difference is that the positioning device also includes a return spring 9, and the return spring 9 is installed on the button pin 10 away from the One end of the button 7 and the other end of the return spring 9 lean against the support rod; The extension action of the button 7 is realized by the return spring 9 .

Abstract

The invention relates to elevator car roof maintenance devices, in particular to an elevator car roof maintenance safety protecting device which comprises a supporting rod and a base. The supporting rod is rotatably arranged on the base, a contact is arranged on the supporting rod, and a contact seat is arranged on the base; when the rotating rod rotates to a horizontal position, the contact is connected with the contact seat, a circuit which controls running of an elevator is on, and the elevator is in a normal running state; the supporting rod rotates to a vertical position, the contact leaves the contact seat, the circuit which controls running of the elevator is off, a band-type brake works, and the elevator is in a safety maintenance state. The contact on the supporting rod is connected with or separated from the contact seat on the base to switch states of the elevator by changing states of the supporting rod, and the contact is in the normal running state when the contact is connected with the contact seat and is in the safety maintenance state when the contact is separated from the contact seat.

Description

technical field [0001] The invention relates to an elevator car top maintenance device, in particular to an elevator car top maintenance safety protection device. Background technique [0002] With the continuous progress and development of society, the number of high-rise buildings continues to increase, and elevators have become an indispensable means of transportation between buildings. In order to ensure the safe operation of the elevator, a car top elevator maintenance device needs to be installed. The car top inspection device is usually installed and fixed on the outer top of the car. [0003] But there is potential safety hazard in the overhaul device on the car at present. Due to the lack of space on the top floor of the elevator and the car, the staff cannot turn around, and maintenance personnel or passengers may accidentally touch the button switch, resulting in changes in the working status of the elevator, and even accidents. There is no protective cover aro...
