Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, in particular to a tool for rapid elevator maintenance and fault warning. Background Art

[0002] As a modern mechanical means of transportation, lifts have become one of the indispensable equipment in people's daily lives and are widely used in shopping malls, high-rise office buildings and high-rise residential buildings. However, as a means of transportation, elevators travel between high-rise buildings and the ground, which is inherently dangerous. Therefore, they need to be regularly inspected and maintained to ensure the normal operation of the elevator and the safety of passengers and goods carried. Among them, traction elevators drive the car through traction ropes, fixed pulleys and movable pulleys. Usually, the traction ropes are in groups of multiple ropes, and the traction ropes will rust after working for a period of time. In order to ensure the safety of elevator operation, elevators need to be inspected more frequently.

[0003] The invention patent with authorization announcement number CN109704173A discloses an elevator traction rope maintenance tool and its maintenance process. The invention includes a driving motor, a rotating shaft, a take-up reel, a pay-off reel, and a detection line. A fixed seat is provided on the driving motor, and the driving motor drives the rotating shaft to rotate. The take-up reel and the pay-off reel are both fixed on the rotating shaft. One end of the detection line is wound and fixed on the take-up reel, and the other end of the detection line is reversely wound and fixed on the pay-off reel. The detection line is wound on the pay-off reel and has the advantage of being rusted by friction between the detection line and the traction rope, making it easy for people to quickly distinguish whether the traction rope is rusted.

[0004] Although the above invention can make it easier for people to distinguish whether rust has occurred, in actual use, the device is installed inside the elevator shaft, and the lighting conditions are poor, so it is still inconvenient to distinguish through the detection line. In view of this, we propose an elevator rapid maintenance and fault warning tool. Utility Model Content

Through the above mechanism, the resolution if rust is found during the inspection process is increased, so that the staff can more conveniently and quickly distinguish whether rust is present.

[0028] It should be added that a rust indicator is placed in the reagent box 352, and the lower end of the groove wheel 343 is located below the rust indicator liquid level. The detection line in the detection mechanism 2 is unwound from the pay-off reel, passes through the detection box 35, and then returns to the take-up reel, and the detection line passes through the groove wheel 343.

[0029] Furthermore, upper grooves 341 are provided on both sides of the upper surface of the upper cover 34, a support rod 342 is welded in the middle of the lower surface of the upper cover 34, and a groove wheel 343 is installed at the lower end of the support rod 342, through which the detection line is pressed into the rust indicator.

[0030] Furthermore, card slots 351 are provided on the upper surfaces of the front and rear sides of the detection box 35, and a reagent box 352 is slidably connected inside the detection box 35. Card blocks 354 are provided on the upper ends of the front and rear surfaces of the reagent box 352, and lower grooves 353 are provided on the top ends of the left and right surfaces of the reagent box 352 to facilitate the removal of the reagent box 352.

[0031] In this embodiment, a through groove is provided on the upper surface of the support column 31 for the sliding connection of the moving rod 32 , and the lower end of the limiting bolt 33 is in close contact with the upper surface of the moving rod 32 , and the limiting bolt 33 can limit the sliding of the moving rod 32 in the support column 31 .

[0032] In this embodiment, a mounting base is provided at the lower side of the driving motor 1 , and the warning mechanism 3 is welded to the front right side of the upper surface of the mounting base. The warning mechanism 3 is located in front of the detection mechanism 2 as a whole.

[0033] In this embodiment, the detection box 35 is made of transparent plastic, and the reagent box 352 is made of transparent plastic, which is convenient for observing the color of the internal rust indicator.

Then, the upper cover 34 is opened, and the detection line is taken out from the pay-off reel, and after passing through the traction rope to be detected, it is attached to the groove wheel 343 to prevent and pass through the upper groove 341 on the upper cover 34, and then sent into the take-up reel, and then the upper cover 34 is covered, and the position of the detection line is adjusted to ensure that the detection line is located in the upper groove 341 and the lower groove 353 to prevent the detection line from affecting the closing of the upper cover 34, and then the drive motor 1 is started, and the detection mechanism 2 is used to detect whether there is rust on the outer surface of the traction rope. The rust enters the detection box 35 along with the traction rope and reacts with the rust indicator;

[0038] After the rust indicator is used, the upper cover 34 is opened, and the reagent kit 352 is taken out to replace the rust indicator.
