Description

Device for judging rotation direction of elevator traction machine

Technical Field

The utility model relates to an elevator technical field specifically is a judge device of elevator hauler direction of rotation.

Background

With the continuous development of elevator technology, the safety performance of an elevator is also continuously improved, but when the elevator without a machine room is subjected to rescue remotely, the rescue direction is generally judged by observing the running direction of a steel wire rope through an observation hole, so that the elevator is quite inconvenient and cannot be clearly seen in dark light, a searchlight needs to be added, or the rescue direction is judged by a control cabinet nixie tube according to some specific methods of the nixie tube provided by a control system, so that the elevator has the requirement of strong professional performance and is not intuitive; or the direction of the steel wire rope or the rotating direction of the traction sheave is observed by a camera arranged in the shaft to judge the rescue running direction of the elevator, but equipment such as the camera needs to be added, and the manufacturing cost is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a judge device of elevator hauler direction of rotation, simple direct observation elevator rescue more can solve elevator direction when the rescue among the prior art and judge directly perceived inadequately, and professional skill judges to require highly, the not strong problem of general commonality.

In order to achieve the above object, the utility model provides a following technical scheme:

a device for judging the rotation direction of an elevator tractor comprises the tractor, a traction sheave, a fixed support a, a fixed support b, a sensor, a magnet, a display and an emergency power supply, wherein the magnet is adsorbed on the traction sheave of a moving part of the tractor, the fixed support a and the fixed support b are fixed on the tractor, the sensor is fixedly arranged on the fixed support a and the fixed support b, the sensor is electrically connected with the display, and the display is connected with the emergency power supply.

Furthermore, the sensor is a bidirectional positive and negative detection-Hall sensor and is provided with two paths of sensing signals, and the phase difference of the two paths of sensing signals is in the period of 1/8-3/8.

Further, the display receives signals of the A/B channels of the sensor.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses an arrow point about the display, and then the traffic direction of elevator when knowing the rescue directly perceivedly has improved the ageing and the security of rescue greatly.

2. The bidirectional positive and negative detection Hall sensor is adopted to judge the rotating direction of the traction sheave, so that the traction sheave has the advantages of simple structure, low cost and stable performance.

3. The utility model discloses have general commonality, observe the difference of the method of elevator direction when having avoided the rescue of different producer designs, reduced the requirement to the professional skill level of rescue personnel, it is more simple and convenient to the direction of elevator rescue, and be independent of elevator control system, have the supplementary effect of verifying the judgement.

Drawings

Fig. 1 is a schematic diagram of an electrical control circuit according to the present invention.

In the figure: 1. a traction machine; 2. a traction sheave; 3. a fixed bracket a; 4. a fixed bracket b; 5. a sensor; 6. a magnet; 7. a display; 8. an emergency power supply.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the device for judging the rotation direction of the elevator traction machine comprises a traction machine 1, a traction sheave 2, a fixed support a3, a fixed support b4, a sensor 5, a magnet 6, a display 7 and an emergency power supply 8, wherein the magnet 6 is adsorbed on the traction sheave 2 which is a moving part of the traction machine 1, the fixed support a3 and the fixed support b4 are fixed on the traction machine 1, the sensor 5 is fixedly arranged on the fixed support a3 and the fixed support b4, the sensor 5 is electrically connected with the display 7, and the display 7 is connected with the emergency power supply 8. An emergency power supply 8 supplies power to the sensor 5 and the display 7 and outputs power at all times whether there is a power failure, such as the example DC12V, and this emergency power supply 8 uses an intercom UPS power supply that is associated with the elevator. The emergency power supply 8 supplies power to the sensor 5 and the display 7, the sensor 5 fixed on the traction machine 1 detects a trigger signal of the magnet 6 arranged on the traction sheave 2, the sensor 5 transmits a rotation signal of the traction sheave 2 to the display 7 in the control cabinet, and the running direction of the elevator is displayed by an up-down arrow.

The sensor 5 is a bidirectional positive and negative detection Hall sensor and is provided with two paths of sensing signals, the phase difference of the two paths of signals is within 1/8-3/8 periods, the magnet 6 triggers the sensor 5, the sensor 5 transmits the A/B signals to the display 7 of the control cabinet, and the display 7 receives the A/B signals of the sensor 5 and displays the uplink or downlink direction through an arrow. When the arrow direction of the display 7 is opposite to the running direction of the elevator rescue, the exchanging sensor 5 is connected to A, B signals of the display, and the running direction of the elevator is ensured to be consistent with the arrow direction of the display 7.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
