Description

Technical Field

[0001] The present invention relates to the technical field of elevator performance testing, and in particular to an elevator vibration testing device. Background Art

[0002] During the operation of an elevator, the vibrations it generates mostly come from the shaking and jumping of passengers. Excessive vibration is detrimental to the operation of the elevator, affecting not only the riding experience of passengers but also the safety of the elevator operation. For this reason, a suppression device needs to be added to the elevator system to suppress the vibration of the elevator. However, the suppression device needs to be configured according to the vibration characteristics of the elevator. In the existing technology, manual or equipment simulation of passenger vibration is usually used to collect the vibration characteristics of the elevator. However, manual simulation may be dangerous to people when extreme situations are involved, and the test equipment in the existing technology cannot fully simulate the various forces applied by passengers to the elevator.

[0045] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0046] like Figures 1 to 5As shown, an embodiment of the present invention discloses an elevator vibration test device, which is used to be set in the car 100 of the elevator system. The elevator vibration test device includes: a base plate seat 41, a lifting plate seat 42, a translation plate seat 43, a first drive mechanism 10, a second drive mechanism 20, a third drive mechanism 30, a swing mechanism 50 and a vibrating mechanism 60.

[0047] The first drive mechanism 10 includes a ground rail 12, a first servo motor 11, a first commutator 14, and running wheels 13. Two ground rails 12 are arranged along the width of the car 100. The running wheels 13 are mounted at the bottom of the four corners of the base plate base 41 and rest on the ground rails 12, allowing the base plate base 41 to move along the ground rails 12 in the width direction of the car 100. The first servo motor 11 is mounted on one side of the base plate base 41, and a first commutator 14 is provided on one side of each running wheel 13. The first servo motor 11 connects all the first commutators 14 via a rotating rod. When the first servo motor 11 is running, it drives the first commutator 14 to rotate, thereby driving the running wheels 13 to move on the ground rail 12, thereby adjusting the position of the base plate base 41 in the width direction. When the first servo motor 11 stops running, it inhibits the running wheels 13 from rotating, thereby maintaining the adjusted position of the base plate base 41.

[0048] The lifting plate seat 42 is disposed above the base plate seat 41 . The second driving mechanism 20 includes a second servo motor 21 , a screw 22 , a second commutator 25 and a nut sleeve 23 . A screw rod 22 is vertically fixed above the top corner position of each base plate seat 41, and a nut sleeve 23 is installed at the bottom of the top corner of the lifting plate corresponding to the screw rod 22. The screw rod 22 passes through the nut sleeve 23 and forms a spiral transmission with the nut sleeve 23. A second commutator 25 meshing with the nut sleeve 23 is provided on one side of each nut sleeve 23. The second servo motor 21 is fixed to the bottom of the lifting plate seat 42 and is connected to the four second commutators 25 through the connecting rod 24, thereby driving the four second commutators 25 to rotate synchronously. The four second commutators 25 drive the nut sleeve 23 to rotate synchronously, so that the lifting plate seat 42 can be raised and lowered, thereby adjusting the height of the lifting plate seat 42. When the second servo motor 21 stops running, the second servo motor 21 has a suppressive effect on the lifting plate seat 42 so that the lifting plate seat 42 can be maintained at the adjusted height.

[0049] The translation plate seat 43 is arranged above the lifting plate seat 42, and the third driving mechanism 30 includes: a third servo motor 31, a lead screw 32, a nut 33, a slide rail 34 and a slider 35; the lead screw 32 is arranged below the translation plate seat 43 along the depth direction of the car 100, the third servo motor 31 is installed on the lifting plate seat 42 and is used to drive the lead screw 32 to rotate, the nut 33 is installed at the bottom of the translation plate seat 43, the lead screw 32 passes through the nut 33 and forms a spiral transmission with the nut 33, the slide rail 34 is arranged on the lifting plate seat 42 and arranged along the depth direction of the car 100, the slider 35 is installed at the bottom of the translation plate seat 43 and slides with the slide rail 34. In this way, the third servo motor 31 runs to drive the lead screw 32 to rotate, and the lead screw 32 drives the translation plate seat 43 to move along the depth direction of the car 100 by cooperating with the nut 33, so that the position of the translation plate seat 43 in the depth direction can be adjusted.

[0050] Based on the above, it can be known that through the cooperation of the three driving mechanisms and the three seat plates, the translation plate seat 43 can be adjusted to any spatial position within a certain spatial range in the car 100.

[0051] The swing mechanism 50 and the vibrating mechanism 60 are both arranged on the translation plate seat 43. The swing mechanism 50 is used to provide impact in the horizontal direction to simulate the shaking of the passenger, and the vibrating mechanism 60 is used to provide impact in the vertical direction to simulate the jumping of the passenger.

[0052] The swing mechanism 50 specifically includes two, each comprising: a bidirectional cylinder 51, a counterweight mounting frame 52, a counterweight plate 533, a bracket 54, and a guide rod 55. The bracket 54 is located on either side of the bidirectional cylinder 51 in the axial direction, with two guide rods 55 disposed between the two brackets 54. The counterweight mounting frame 52 includes a rear plate 521 and a core shaft 522 disposed on the rear front plate surface. The heads of the two piston rods 511 of the bidirectional cylinder 51 are both connected to the counterweight mounting frame 52 and the rear plate 521. The guide rods 55 pass through the rear plate 521 to form a sliding fit with the counterweight mounting frame 52. There are multiple counterweight plates 533, which can be selectively mounted on the core shaft 522. In this way, the operation of the bidirectional cylinder 51 causes the piston rods 511 on both sides to move synchronously, thereby driving the counterweight plates 533 to produce horizontal impacts.

[0053] like Figure 5 As shown, the two swing mechanisms 50 are arranged perpendicular to each other, and one of the swing mechanisms 50 is located at the symmetrical center in the width direction of the car 100. In this way, the two swing mechanisms 50 operate separately to provide impacts in the width direction and the depth direction respectively. By controlling the operating speed and stroke of the counterweight plates 533 of the two swing mechanisms 50, it is possible to provide impacts in any horizontal direction, thereby simulating the shaking of passengers in any direction.

[0054] The vibrating mechanism 60 includes a vibrating motor 61, a vibrating mounting frame 62, and multiple vibrating discs 63. The output shaft of the vibrating motor 61 is eccentrically connected to the vibrating mounting frame 62. The vibrating mounting frame 62 has a splined shaft, and multiple vibrating discs 63 are selectively mounted on the splined shaft. The vibrating motor 61 drives the vibrating discs 63 to rotate, thereby impacting the car 100 vertically, thereby simulating the bouncing of passengers. Preferably, the vibrating mechanism 60 is arranged symmetrically across the width of the translation plate base 43.

[0055] Based on the above, it can be seen that adjusting the spatial position of the translation plate seat 43 is equivalent to simulating the adjustment of the center of gravity of the passenger; adjusting the impact stroke and impact frequency of the swing mechanism 50 and the vibration mechanism 60 is equivalent to simulating the amplitude and frequency of the shaking and jumping of the passenger; adjusting the weight of the configuration plate of the swing mechanism 50 and the weight of the vibration plate 63 of the vibration mechanism 60 is equivalent to simulating the car 100 carrying passengers of different total weights.

[0056] The key advantages of the elevator vibration test device provided by the present invention are:

[0057] The elevator vibration test device can more comprehensively simulate the impact exerted by passengers on the car 100, thereby making the collected vibration parameters of the car 100 more comprehensive, which is conducive to guiding the configuration of a more reasonable vibration suppression device.
