Abstract

The lock control device of elevator circuit breaker of the utility model is formed by a lock arranged above a circuit breaker, and a sliding bar fixed on the central shaft of the back face of the lock core of the lock; the sliding bar can be rotated 90 degrees following the lock core; when the sliding bar is in vertically downward position, the end of the sliding bar is pressed on an operating rod at the time when the circuit breaker is switched off; the lock is arranged on a fixed frame by which the lock is fixed to a frame arranged on the wall. When the key is rotated and the sliding bar is rotated to the vertically downward position following the lock, the circuit breaker is locked at a fixed-position in a switched off state; inversely, when the key is rotated to the negative direction, and the sliding bar is rotated to horizontal position, the circuit breaker can be switched on newly. The utility model has the advantages of simple structure and easy installation, and provides dependable assurance for the elevator maintenance and safe operation.

Description

Ladder circuit breaker lock control device

Technical field

The utility model relates to the lock control devices of low-voltage circuit breaker, especially a kind of lock control devices that is used to stop elevator supply circuit breaker combined floodgate.

Background technology

Existing elevator supply circuit breaker does not all have lock control devices, and when elevator needed repairing, the maintenance personal was left behind the breaker operator bar in the switch-box, and the elevator outage can not be moved.When other people when mistakenly circuit breaker being closed, great human casualty accident may take place because of ignorant, so how can be the problem of pendulum in face of the elevator industry scientific and technical personnel with the fixed position of lock for circuit breaker due to outage.The patent No. is " 01815144.2 ", " locking device of plug in circuit breaker ", " 00106479.7 ", " circuit breaker handle locking device ", " 93107180.1 ", " flap type locking device that is used for circuit breaker " all is to adopt complicated structure that the control crank of circuit breaker is locked in the fixed position, because the complex structure of these devices, so manufacture difficulty is big, cost is high.

Summary of the invention

The purpose of this utility model be to overcome above-mentioned the deficiencies in the prior art and defective for elevator industry provide a kind of simple in structure, be easy to service-strong elevator circuit breaker lock control device is installed.

The technical scheme that the utility model adopted in order to achieve the above object is: tapered end is equipped with in the top that this elevator circuit breaker lock control device is included in circuit breaker, be installed with the slide bar that to do 90 degree rotations with lock core on the lock core central shaft of tapered end, slide bar is vertically downward the time, action bars when its end disconnects with circuit breaker is pressed mutually, makes the position of breaker operator rod lock when disconnecting; Fixed mount is equipped with at the tapered end back side, and by fixed mount tapered end and the framework that is installed on the body of wall is fixed; The tapered end back side is provided with spacing prominent point, and the upper end of slide bar is provided with restriction protrusion, and slide bar is vertically downward the time, and this projection and projection offset.

The utility model compared with prior art simplifies the structure greatly, installs easily, has reduced manufacturing cost, and the fixed position when it can make the circuit breaker manipulation handle lock fix on disconnection is to reach the purpose of safe handling elevator.

Embodiment

As shown in the figure, circuit breaker 5 is housed in the elevator source box, tapered end 1 is positioned at the circuit breaker top, fixed mount 3 is equipped with at tapered end 1 back side, and the lock core central shaft that slide bar 2 passes on fixed mount 3 centre bores and the tapered end 1 is fixed, and this slide bar can be done 90 degree rotations with tapered end, slide bar 2 is vertically downward the time, press mutually with circuit breaker 5 action bars 9 its end, can write eye-catching " No switching on " poster on slide bar 2, to prevent other people misoperation.The tapered end back side is provided with spacing prominent point 7, and the upper end of slide bar is provided with restriction protrusion 8, and slide bar is vertically downward the time, and this projection offsets with prominent point, rotates with restriction slide bar 2 again.Fixed mount 3 is installed on the framework 4, and this lock control devices is installed on the body of wall with framework 4.

During use, key 6 inserts tapered end 1 and turns clockwise, and the joystick 9 when drive slide bar 2 disconnects the end vertically downward with circuit breaker 5 is pressed mutually, and lock for circuit breaker is fixed on the open position, and this moment, key can just take out from tapered end.Be rotated counterclockwise 90 when spending when inserting key, slide bar 3 is horizontal, and the joystick of circuit breaker can be pushed to again, makes breaker closing.

Claims

1, a kind of lock control devices of elevator circuit breaker, it is characterized in that tapered end (1) being housed in described circuit breaker (5) top, be installed with the slide bar (2) that to do 90 degree rotations with lock core on the central shaft of tapered end, slide bar is vertically downward the time, action bars (9) when its end disconnects with circuit breaker is pressed mutually, makes the position of breaker operator rod lock when disconnecting.

2, the lock control devices of elevator circuit breaker according to claim 1 is characterized in that the described tapered end back side is provided with spacing prominent point (7), and the upper end of slide bar is provided with restriction protrusion (8), and slide bar is vertically downward the time, and this projection offsets with prominent point.

3, the lock control devices of elevator circuit breaker according to claim 1 and 2 is characterized in that the described tapered end back side is equipped with fixed mount (3), and fixed mount is positioned at the top of circuit breaker.

4, the lock control devices of elevator circuit breaker according to claim 3, the framework (4) on it is characterized in that described fixed mount and being installed in body of wall is connected.
