Description

Technical Field

[0001] The present invention relates to the technical field of component testing, and more particularly to an elevator door testing device. Background Art

[0002] The mechanical stress strength test device for elevator door components plays an important role in the safety and reliability assessment of elevator door components. It mainly simulates various mechanical stress impact force tests that elevator door components may encounter in actual use, so that the test device can verify whether the mechanical strength of elevator door components meets safety requirements. This helps to ensure that elevator door components will not be deformed, cracked or damaged when subjected to external forces, thereby ensuring the safety of passengers.

[0003] Among the existing public technical documents, the Chinese patent announcement number CN217211834U discloses a test device for elevator door panel impact. This technology mainly uses the pendulum rod to have magnetic force on the pendulum, which can control the release and absorption of the pendulum. When the elevator door panel needs to be impacted, the electromagnet is powered off, and the suction force on the pendulum is lost, so that the pendulum falls naturally and completes the impact on the elevator door panel. When the pendulum needs to impact the elevator door panel again, the electromagnet is powered on, and the winding mechanism controls the pendulum rod to swing downward, so that the electromagnet absorbs the pendulum again, and the winding mechanism drives the pendulum rod to reset the pendulum to its initial position before release. However, there are still the following defects when testing elevator door parts.

[0035] The method of using the elevator door testing device of the present invention is as follows: First, when the present invention performs a synchronous tilt test on components, the mounting plate 19 is fixed to the test table by bolts, the mounting plate 19 supports the positioning slot frame 17, the positioning slot frame 17 supports two support blocks 32, so that the two support blocks 32 are stably supported and used, and the positioning slot frame 17 also provides a stable supporting force for the slot column 1. At the same time, the positioning slot frame 17 positions and supports two elevator door components 18, and the two elevator door components 18 are placed on the inner wall of the positioning slot frame 17 for testing.

[0036] At the same time, the controller 20 starts the reduction motor 5, and the reduction motor 5 drives the linkage screw 2 to rotate. The linkage screw 2 rotates inside the slot column 1. At the same time, the linkage screw 2 drives the sleeve block 3 to move backward under the action of the thread, and the sleeve block 3 makes the connecting ring 4 move backward, and the connecting ring 4 slides backward along the outer wall of the slot column 1, and the connecting ring 4 drives the two hinge blocks 6 to move backward, and the hinge block 6 drives the connecting shaft 7 to move backward, and the connecting shaft 7 drives the bottom end of the sleeve rod 8 to move backward, and the sleeve rod 8 drives the push shaft 9 to tilt upward, and the push shaft 9 drives the concave block 10 to tilt upward, and the concave block 10 makes the impact cylinder 11 tilt upward, and the impact cylinder 11 drives the impact rod 12 to tilt upward, and the impact rod 12 makes the sleeve 14 tilt upward along the inner wall of the tilt frame 16.

[0037] At the same time, the sleeve 14 drives the two limit rings 15 to move upwards, and the two limit rings 15 move upwards along the tilting frame 16, so that the impact rod 12 drives the front test ball 13 to move upwards. At the same time, the impact rod 12 drives the sliding frame 21 to move upwards, and the impact rod 12 slides to the left along the inner wall of the sliding frame 21, and the other impact rod 12 slides to the right along the inner wall of the other sliding frame 21. At the same time, the controller 20 starts the two impact electric cylinders 11, and the impact electric cylinder 11 pushes the impact rod 12 to move backwards, and the impact rod 12 drives the front test ball 13 to move backwards, and the front test ball 13 impacts the elevator door component 18, and then the impact electric cylinder 11 drives the impact rod 12 to retract forward, and the impact rod 12 drives the front test ball 13 away from the elevator door component 18. In this way, as the impact electric cylinder 11 continuously drives the impact rod 12 to move back and forth, the front test ball 13 will also continuously perform strength tests on the elevator door component 18, so that the front of the elevator door component 18 can be tested for tilted synchronous displacement.

[0038] At the same time, when the present invention performs lateral synchronous testing of parts, when the impact rod 12 moves upward, it will drive the slide frame 21 to move upward synchronously, and the slide frame 21 drives the linkage bar 22 to move upward. The linkage bar 22 enables the support frame 23 to stably realize the upward operation, and at the same time, the linkage bar 22 moves upward along the inner wall of the guide column 31, and the positioning groove frame 17 supports the two support blocks 32, and the support blocks 32 provide stable support force for the guide column 31.

As the driving motor 25 continuously switches back and forth, the two lateral test balls 30 respectively perform synchronous strength test on the sides of the two elevator door components 18.

[0040] At the same time, when the present invention performs a synchronous test on the top of a component, the transmission motor 35 is started through the controller 20, the transmission motor 35 drives the moving screw 34 to rotate, the moving screw 34 drives the articulated sleeve 36 to move left under the action of the thread, the articulated sleeve 36 drives the reciprocating motor 38 to move left, the reciprocating motor 38 causes the rotating rod 37 to move left, the rotating rod 37 causes the sleeve strip 39 to move left, and the sleeve strip 39 drives the vertical test ball 40 to move left.

The sleeve strip 39 makes the vertical test ball 40 rotate counterclockwise, and the vertical test ball 40 performs a strength test on the top of the elevator door component 18 counterclockwise. Then the reciprocating motor 38 is started to drive the rotating rod 37 to rotate clockwise, and the rotating rod 37 drives the sleeve strip 39 to rotate clockwise, and the sleeve strip 39 drives the vertical test ball 40 to rotate clockwise for reset. As the reciprocating motor 38 continues to rotate back and forth, the vertical test ball 40 can perform a moving strength test on the top of the elevator door component 18.

[0042] Finally, when the present invention checks the test records, after the elevator door components 18 are tested, the depression status of the two elevator door components 18 can be checked. If no depression problem occurs, the quality of the elevator door components 18 is qualified. If there is a large depression position, the quality of the elevator door components 18 is unqualified.
