[0021] Example 1:

[0022] See Figures 1-4This utility model discloses an elevator testing platform for conducting pendulum impact tests on elevator doors. It includes a testing platform 1, a fixing part 11 for securing the elevator door, and a testing mechanism for conducting the pendulum test. The testing mechanism includes a pendulum 2, a sling 4 connected to the pendulum 2, and a pendulum support 5. A platform support 12 is provided on the testing platform 1. The upper end of the pendulum support 5 is hinged to the platform support 12 via a hinge. The sling 4 is connected to one end of the pendulum support 5 near the hinge. A pendulum clamping device is provided at the end of the pendulum support 5 away from the hinge for cooperating with the pendulum 2, thereby fixing and releasing the pendulum 2.

[0023] See Figure 1 , Figure 3 and Figure 4 A flipping drive cylinder 8 is provided between the pendulum support 5 and the platform support 12 for driving the pendulum support 5 to flip around the hinge. The two ends of the flipping drive cylinder 8 are respectively hinged to the pendulum support 5 and the platform support 12. The pendulum support 5 is designed to be flip-up, facilitating the retrieval of the test pendulum 2. When releasing the pendulum, the flip-up drive cylinder 8 controls the pendulum support 5 to flip upwards, placing the test pendulum 2 at a certain height. Then, the test pendulum 2 is released through the pendulum clamping device. Under the influence of gravity, the test pendulum 2 impacts the elevator door, thus conducting a pendulum impact test on the elevator door. When it is necessary to retrieve the test pendulum 2, the flip-up drive cylinder 8 drives the pendulum support 5 to flip towards the test pendulum 2 until the pendulum clamping device contacts the test pendulum 2. The pendulum clamping device then clamps and fixes the test pendulum 2 again. Finally, the flip-up drive cylinder 8 controls the pendulum support 5 to flip upwards again, thus completing the automatic retrieval of the test pendulum 2. This embodiment facilitates pendulum impact tests on elevator doors, enabling automatic release and retrieval of the test pendulum 2. It has a high degree of automation, reduces errors caused by manual operation during the test, and improves test safety.

[0024] Specifically, the pendulum clamping device includes a block 6 mounted on the pendulum support 5. A receiving cavity 61 adapted to the detection pendulum 2 is provided on the side of the block 6 near the detection pendulum 2. Both sides of the receiving cavity 61 are provided with top blocks 62 for engaging with the side walls of the detection pendulum 2, and a linear actuator for driving the top blocks 62 to move. When the top blocks 62 extend, they engage with the detection pendulum 2, thereby clamping and fixing the detection pendulum 2. When the top blocks 62 retract, the detection pendulum 2 loses the constraint of the top blocks 62 and can fall freely, thus performing the pendulum test.

[0025] Example 2:

[0026] See Figure 3 , Figure 4 Based on Embodiment 1, a winch 7 is provided on the pendulum support 5, and one end of the sling 4 is connected to the winch 7. The extension length of the sling 4 can be adjusted by the winch 7, thereby adjusting the swing amplitude of the detection pendulum 2 to meet various detection needs.

[0027] Correspondingly, see Figure 3 , Figure 4 The pendulum support 5 includes support bars 51 on both sides and a connecting support 52 between the support bars 51 on both sides. The block 6 is slidably connected to the support bars 51 on both sides. Each support bar 51 is provided with a rack 511 arranged along its length. The block 6 is provided with a gear 63 that meshes with the rack 511 and a gear motor 64 for driving the gear 63 to rotate. In this embodiment, the block 6 is slidably mounted on the support bars 51, and the gear motor 64 meshes with the rack 511 to achieve automatic control of the position of the block 6, realizing automatic adjustment, making it more convenient to use and more accurate.

[0028] The working process of this utility model:

[0029] In the operation of this elevator testing platform, when the pendulum is released, the flipping drive cylinder 8 controls the pendulum support 5 to flip upwards, so that the testing pendulum 2 is at a certain height. Then, the testing pendulum 2 is released through the pendulum clamping device. The testing pendulum 2 impacts the elevator door under the action of gravity, thereby conducting a pendulum impact test on the elevator door. When it is necessary to retrieve the testing pendulum 2, the flipping drive cylinder 8 can drive the pendulum support 5 to flip in the direction of the testing pendulum 2 until the pendulum clamping device contacts the testing pendulum 2. The pendulum clamping device clamps and fixes the testing pendulum 2 again. Then, the flipping drive cylinder 8 controls the pendulum support 5 to flip upwards again, thus completing the automatic retrieval of the testing pendulum 2.
