Detailed Description
Embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the anti-bouncing device for the ultra-high-speed elevator comprises 2 buffer supports 1, a buffer disc spring assembly 2, a buffer pressure spring assembly 3, 2 safety systems 4 and a top cover plate 5;
the 2 buffer brackets 1 are symmetrically fixed at two sides of the compensation device and embedded in the fixing device together with the compensation device;
the top cover plate 5 is arranged right above the 2 buffering supports 1, and the top cover plate 5 and the 2 buffering supports 1 are connected through the buffering disc spring combination 2 and the buffering spring combination 3;
the 2 safety systems 4 are symmetrically arranged on two sides of the top cover plate 5 and fixed on the fixing device;
when the compensation device bounces, the buffer disc spring combination 2 and the buffer spring combination 3 are compressed, the buffer disc spring combination 2 and the buffer spring combination 3 act after being compressed to a specified stroke, the safety system 4 acts to provide a certain buffer distance for the buffer disc spring combination 2 and the buffer spring combination 3, and the buffer disc spring combination 2 and the buffer spring combination 3 disperse and absorb energy generated by bouncing of the compensation device.
In the embodiment, two ends of each buffer bracket 1 are respectively provided with a buffer disc spring combination 2 and two buffer pressure spring combinations 3;
the springs arranged at the two ends of each buffer bracket 1 are symmetrical to each other.
In the embodiment, 2 safety systems 4 are symmetrically arranged on two sides of the center line of the top cover plate 5.
In the embodiment, the 2 buffer supports 1 and the compensation device are fixed through bolts; the buffering disc spring combination 2 and the buffering pressure spring combination 3 are both arranged on the buffering support 1 through screws and nuts.
Referring to fig. 3, in the embodiment, the safety system 4 includes a base, a fixing plate, a safety gear and a safety gear lifting rod;

The working principle of the invention is as follows: when the compensation device bounces upwards rapidly, the buffer support 1 bounces upwards along with the compensation device, in the process that the buffer support 1 bounces upwards, spring assemblies in 8 buffer pressure spring assemblies 3 and 4 buffer disc spring assemblies 2 are compressed simultaneously, energy generated by the bouncing of the compensation device is dispersed and absorbed, and after the springs are compressed to a specified stroke, a safety gear lifting rod on the safety system 4 pulls a wedge block in the safety gear to clamp a guide rail on the fixing device so as to stop, and the springs are prevented from being compressed and moving upwards continuously. After the spring stops compressing, the absorbed energy of the spring can be slowly dispersed and released, thereby achieving the effects of vibration reduction, buffering and jumping weakening.
