Description

Technical Field

[0001] The utility model relates to the technical field of elevator inspection and detection equipment, in particular to an elevator door opening clearance measuring instrument. Background Art

[0002] Elevator landing doors are an important component of ensuring the safe use of elevators. According to the special equipment safety technical specifications "TSGT7001-2023 Elevator Supervision Inspection and Periodic Inspection Rules" and "TSG T7008-2023 Elevator Self-Test Rules", the following requirements are required: in the opening direction of the fastest door leaf of horizontal sliding and folding landing doors, a force of 150N is applied at the most unfavorable point. For side-opening doors, the gap between the door leaf and the column shall not exceed 30mm; for center-opening doors, the total gap between the door leaves shall not exceed 45mm.

[0003] The current common inspection method involves two people working together, one applying a 150N force with a dynamometer, while the other measures the gap with a vernier caliper or ruler. Because the "worst-case point" is often close to the ground, and metal doors lack a mechanism to secure the dynamometer hook, the measurement team typically has to squat on the ground to apply the force horizontally. This process is time-consuming and labor-intensive, and the measured data is not very accurate.

[0004] The invention patent publication number is: CN113280719 A discloses an elevator door gap measuring ruler that can be operated by one person. However, the device is heavy and occupies a large space, which is not conducive to carrying and storing. In addition, its second clip and first clip are rotatably connected by a hinge. When taking and placing the device, the two clips are easy to rotate, which can easily pinch or bump the operator. Utility Model Content

A connecting shaft 14 passes through the circular ring. The front and rear ends of the connecting shaft 14 are fixedly connected to the first slider 10;

[0047] A gap scale 15 is fixed to the front side of the second slider 9, and a force scale 16 is provided on the front side of the first slider 10. The force scale 16 has a slide groove 17, and a first bolt 18 is provided in the slide groove 17. The first bolt 18 passes through the slide groove 17 and is fixed to the first slider 10; the left end of the force scale 16 is fixed to the left end of the slide plate 11 via a second bolt 19.

[0048] A first vertical slot 20 is defined at the right end of the front side of the first slider 10, corresponding to the scale on the gap scale 15. A second vertical slot 21 is defined on the force scale 16. A third vertical slot 22 is defined at the left end of the front side of the first slider 10, corresponding to the second vertical slot 21. Leftward movement of the slide 11 causes the force scale 16 to move leftward as well. When the second vertical slot 21 aligns with the third vertical slot 22, the tension of the second spring 13 reaches a preset value (150N in the figure), causing the first latch 3 to overcome the resistance of the elevator door and move leftward. When the elevator door opens, the first vertical slot 20 points to the scale on the gap scale 15, allowing the door opening clearance to be read.

[0049] Insert the first and second claws 3 and 4 into the gap between the elevator doors. Grip the first and second handles 1 and 2 and squeeze them inward, causing the second slider 9 to apply a rightward force to the elevator door. Simultaneously, move the upper end of the first handle 1 to the left, thereby driving the slider 11 to the left. At this point, the force scale 16 also moves leftward. Simultaneously, the leftward movement of the slider 11 stretches the second spring 13, thereby pulling the connecting shaft 14 and driving the first slider 10 to apply a leftward force to the elevator door. As the force increases, when the tension of the second spring 13 reaches a preset value, the force applied by the first and second claws 3 and 4 to the elevator door overcomes the resistance of the elevator door. At this point, the first and second claws 3 and 4 move in opposite directions, and the elevator door opens. The elevator door opening gap can be determined by reading the distance between the first and second claws 3 and 4 at this point.

[0050] like Figure 1 As shown, based on the previous embodiment, the utility model provides a ninth embodiment, in which the number of the second claws 4 is two and the width is equal, and the width ratio of the second claw 4 to the first claw 3 of any one of the two second claws 4 is 1:2, so as to ensure that when the measuring instrument applies force to the elevator door, the two ends are evenly stressed and not easily damaged.

[0051] The tour guide telescopic rod and the gap scale in the present invention are both prior arts, which are clearly understood by those skilled in the art and will not be described in detail here.

[0052] The above description is only a preferred embodiment of the present invention and should not be understood as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
