Description

Technical Field

[0001] This invention relates to the field of elevator door testing technology, and in particular to an elevator door strength testing device. Background Technology

[0002] Elevators, as an indispensable vertical transportation tool in modern buildings, are directly related to the safety of passengers' lives and property. The elevator door system, as the direct barrier between passengers and the elevator car and shaft, is a key factor in ensuring the safe operation of the elevator due to its mechanical strength. With the increasing prevalence of high-rise buildings and the continuous increase in elevator usage frequency, elevator doors face higher usage intensity and more complex operating conditions, making their strength testing technology particularly important.

[0003] Elevator doors are subjected to various external forces during daily use, including frequent opening and closing during peak hours, unintentional collisions when passengers are carrying heavy objects, and accidental impacts from children playing. These external forces may cause elevator doors to deform, crack, or even fall off, leading to safety accidents.

[0004] Currently, elevator door strength testing mainly employs two methods: static pressure testing and impact testing, to simulate various stress conditions that may occur during actual use. However, existing testing technologies and equipment have the following problems: current elevator door strength testing equipment is often limited to a single mode of testing; conducting tests in different modes requires the purchase of additional equipment, increasing testing costs. For example, impact testing and static pressure testing typically require different devices, resulting in low testing efficiency; and accurate measurements cannot be conveniently and promptly performed after testing. Summary of the Invention

[0016] The beneficial effects of this invention are as follows: 1. This invention, by setting up an elevator door movement control mechanism, can first fix one side of the door frame by the clamping component of the moving seat, and fix the other side of the door frame by the clamping component of the upper frame. Under the operation of the transport component, the elevator door is moved to a position that matches the stamping mechanism, thereby completing the stamping.

[0019] 4. By incorporating structures such as movable balls, this invention enables the detection control unit to control the detection frame to descend to a specified height when the elevator door moves to the detection position. The movable balls then contact the elevator door surface, and based on the reaction force, the detection spring compresses the wireless pressure sensor, which statically collects information. During dynamic data collection, after the detection frame descends to the specified height and the movable balls contact the elevator door, the movement control motor operates, driving the moving seat to move, allowing the elevator door to smoothly pass through each movable ball. Throughout this process, the wireless pressure sensor collects data in real time. The use of movable balls avoids structural jamming. Attached Figure Description

One end of the guide frame 21 is fixed to the upper end frame 27. The slide seat 20 and the guide frame 21 are connected by the slide seat spring 26. The upper end frame 27 and the movable seat 17 are both equipped with clamping components for fixing the door frame 10 through shafts. The elevator door 11 to be tested is set inside the door frame 10. The transport assembly is used to transport the slide 20, thereby changing the posture of the door frame 10 and the elevator door 11; The stamping mechanism is located above the bottom track 1, and its position is adapted to the position of the elevator door 11. The testing mechanism is located above the bottom track 1 and is used to test the elevator door 11 after it has been stamped by the stamping mechanism. By setting up an elevator door movement control mechanism, one side of the door frame 10 can be fixed by the clamping component of the moving seat 17, and the other side of the door frame 10 can be fixed by the clamping component of the upper frame 27. Under the operation of the transport component, the elevator door 11 is moved to a position that matches the stamping mechanism, thereby completing the stamping. Finally, the strength of the elevator door is tested by the testing mechanism, realizing the automated testing of the elevator door strength.

[0025] To facilitate adjusting the posture of elevator door 11; such as Figure 1 , Figure 3 , Figure 4 As shown, a positioning plate 19 is mounted on one side of the slide 20, and the positioning plate 19 has a plurality of evenly distributed positioning holes 30; the conveying assembly includes: Adjustment frame 22, one end of which is rotatably mounted with a rotating disk 32; Positioning pin 31 is fixed to the outer wall of one side of the rotating disk 32, and the positioning pin 31 is adapted to the positioning hole 30; Rotation control unit, the rotation control unit is used to control the rotation of the rotating disk 32; The telescopic control unit is used to control the movement of the adjustment frame 22 toward the positioning plate 19 or away from the positioning plate 19, so that the positioning pin 31 can be inserted into the positioning hole 30 or leave the positioning hole 30. The lifting control unit is used to control the lifting of the adjusting frame 22. The translation control unit is used to control the movement of the adjustment frame 22 along the bottom track 1.

[0026] To facilitate control of the rotation of the positioning plate 19; such as Figure 4 As shown, the rotation control unit includes a rotation control motor 25, which is mounted on the outer wall of one side of the adjustment frame 22. A drive gear 34 is mounted on the output end of the rotation control motor 25, and a driven gear 33 is mounted on the outer wall of one side of the rotating disk 32.

A track moving motor 4 for controlling the rotation of the transverse screw is installed on one side of the support frame 7. By setting up structures such as a translation control unit, when it is necessary to adjust the posture of the elevator door 11, the translation control unit and the lifting control unit work to move the rotating disk 32 to one side of the positioning disk 19. The telescopic control unit works to insert the positioning pin 31 into the positioning hole 30 of the positioning disk 19. With the cooperation of the translation control unit, the lifting control unit and the rotation control unit, the axis of the clamping component is deflected, and the slide block 20 is lifted from the first slide rail 3, so that the elevator door 11 moves to a suitable angle for detection. When the elevator door 11 needs to be transported horizontally, the slide 20 is placed on the first slide rail 3. Based on the operation of the motion control motor 2, the moving seat 17 is controlled to move, thereby driving the entire structure to move horizontally.

[0030] like Figure 4 As shown, the clamping assembly includes: Clamping frame 18, one end of clamping frame 18 is hinged to upper frame 27; Clamping frame 28 is slidably connected to the inner wall of one side of clamping frame 18; Adjusting screw 29 is threadedly connected to the inner wall of clamping frame 18, and one end of adjusting screw 29 is rotatably mounted on clamping frame 28.

A detection hammer 15 is detachably mounted on the output end of the first telescopic cylinder 13. By setting up structures such as the second telescopic cylinder 35, the first telescopic cylinder 13, and the detection hammer 15, the position of the detection hammer 15 can be adjusted according to requirements. During testing, based on the operation of the first telescopic cylinder 13, the detection hammer 15 is used to perform a stamping test on the elevator door 11. Since the angle of the elevator door 11 is adjustable, it can simulate stamping in different directions.

[0032] For ease of detection; such as Figure 1 , Figure 6 As shown, the testing mechanism includes: Inspection frame 41 is located above the bottom track 1; The detection cylinder 16 is detachably mounted on the detection frame 41, and multiple detection cylinders 16 are arranged in an array.

After the movable ball 44 contacts the elevator door 11, the movement control motor 2 operates, driving the moving seat 17 to move, so that the elevator door 11 smoothly passes through each movable ball 44. During the process, the wireless pressure sensor 45 collects data in real time. Because movable balls 44 are used, structural jamming is avoided.
