Description

Positioning auxiliary device used during maintenance of elevator car

Technical Field

The utility model belongs to the technical field of the elevator and specifically relates to a location auxiliary device for when elevator car overhauls has been related to.

Background

The car is an important component of a traction elevator and is generally used for carrying people or objects.

The elevator needs regular maintenance, during the maintenance, a maintainer is required to go up to the top of the car to check well parts (such as a hall door, a counterweight, a steel wire rope, a traveling cable and the like), and in the process, the elevator car needs to be stopped to a proper position first and then is subjected to overhauling operation by going up to the top of the car by the maintainer. At present, due to the existence of the floor height between floors, after the elevator car normally stops, the top of the elevator car is a certain distance away from the door opening of the landing door on the previous floor, for example, the elevator normally stops at floor 1, the landing door of floor 2 is generally a distance of 0.5-3m away from the top of the elevator car, the distance depends on the floor height of the floor, and if the floor height of some commercial buildings or the raised floors is larger, the distance can reach 3m. The inspection personnel can go down to the top of the elevator car from the landing door opening on the upper floor (for example, the elevator normally stops at floor 1, and goes down from the landing door on floor 2 to the top of the elevator car), so that the inspection personnel is dangerous and inconvenient to climb up and down.

The mode that adopts at present generally is that the control elevator stops at the position that car top exceeds hall door gate 30cm height, makes things convenient for maintainer upper and lower car top like this. However, this method has problems: on one hand, as the landing door is closed (the elevator system has use safety limitation, even if the elevator system is in an open state during no-load maintenance, the elevator cannot run), a maintainer cannot visually observe the position of the elevator car, can only control the elevator to manually open the landing door to check after stopping, and stops again and repeats the operation after the landing door is required to be closed again and the elevator is controlled to run if the stopping position is not suitable, until the position of the elevator car is suitable for the maintainer to go up and down, the use is very inconvenient; on the other hand, the brake operation of the elevator at the abnormal stopping position is realized through an emergency brake system of the elevator, and belongs to the operation category of emergency brake.

Disclosure of Invention

In order to solve the problem that exists among the background art, the utility model provides a location auxiliary device when being used for elevator car to overhaul.

The utility model provides a location auxiliary device for when elevator car overhauls, includes casing, detecting element, warning unit and interim fixed unit, detecting element with it sets up respectively to remind the unit in the casing, interim fixed unit sets up the casing outside, correspond on the casing detecting element is provided with the detection mouth and corresponds it is provided with and reminds the mouth to remind the unit.

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 of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, a positioning auxiliary device for elevator car maintenance comprises a housing 1, a detection unit, a reminding unit and a temporary fixing unit, wherein the detection unit and the reminding unit are respectively arranged in the housing 1, the temporary fixing unit is arranged outside the housing 1, a detection port 2 is arranged on the housing 1 corresponding to the detection unit, and a reminding port 3 is arranged on the housing corresponding to the reminding unit.

In the embodiment, the thickness of the positioning auxiliary device is smaller than the distance between the car and the hall door, and the up-down movement of the elevator car is not influenced when the positioning auxiliary device is fixed on the inner side of the hall door. When the elevator is stopped, a landing door of a certain floor such as the 5 th floor is manually opened (at the moment, the elevator car does not stop at the 5 th floor, and the car should stop at any floor below an operation floor in the embodiment), the shell is temporarily fixed at a proper position on the inner side wall of the landing door through the temporary fixing unit, for example, a position 30cm away from the landing door sill, the landing door is manually closed after the shell is fixed, the elevator is controlled to run, at the moment, the elevator car ascends from the certain floor below the 5 th floor, when the top of the car runs to the shell, the detection unit detects the position of the top of the car, the warning unit is controlled to give an alarm, at the moment, a maintainer controls the elevator to brake, and then the landing door is manually opened and the positioning auxiliary device is taken down. At this moment, the distance between the top of the elevator car and the operation floor is about 30cm like a sill of the 5 th floor, namely the corridor ground distance of the 5 th floor, the height is convenient for a maintainer to go up and down the top of the elevator car, the elevator car can be braked and stopped to a required position only by once control, the operation is safe and convenient, and the damage is small.

In practice, a battery cavity 4 is further arranged in the shell, a switch is further arranged on the shell, and the detection unit and the reminding unit are communicated with the battery cavity 4 through the switch. The battery cavity is a conventional battery cavity for placing a battery to provide power. The switch is used for controlling the connection and disconnection of the detection unit, the reminding unit and the battery. When in use, the switch is closed, and the switch is opened after use.

In this embodiment, the reminding unit is a buzzer, and the temporary fixing unit is a magnet 5. In reality, the hall door leaves of the elevator are all decorated by stainless steel or sprayed with powder, and the internal materials are still iron, so that the temporary magnetic attraction of the shell can be easily fixed at the required position of the hall door through the magnet 5.

Specifically, the detection unit is a diffuse reflection sensor, and a transmitting and receiving signal end of the diffuse reflection sensor is arranged at the detection port. In this embodiment, the diffuse reflection sensor is an NPN type diffuse reflection photoelectric switch, and the model is E3Z-D61. Under normal conditions, the NPN diffuse reflection photoelectric switch U1 is normally closed, the connection is carried out after a signal is detected, the buzzer F1 is communicated with the battery M1 through the NPN diffuse reflection photoelectric switch U1 and the button-type switch K1 on the shell, the switch K1 on the shell is opened during use, the connection is carried out after the NPN diffuse reflection photoelectric switch U1 detects an object, the buzzer F1 is connected with the battery M1 to carry out buzzing reminding, the switch K1 on the shell is disconnected or the NPN diffuse reflection photoelectric switch U1 cannot detect the object, and the buzzer F1 is disconnected with the battery M1.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
