AI Technical Summary

Technical Problem

When simulating the flexible installation of shipborne equipment, how can we ensure that the impact point of the base remains consistent with each impact so that the load frame can reliably vibrate at a certain frequency? Especially when the weight of the load frame and the base is large, how can we ensure the accuracy and repeatability of the impact point during lifting and releasing?

Method used

A lifting mechanism was designed, including a frame, a drive source, a first boom, and a release device. The drive source is connected by a pull rope. The first boom and the second boom are arranged in parallel to ensure that the release device and the load frame move along the same arc trajectory. Combined with the elastic pull rope and the buffer block, reliable vibration of the load frame is achieved.

Benefits of technology

It achieves the accuracy and reliability of the impact point and frequency of the load frame in each impact, simplifies the operation process, reduces the testing cost, and realistically simulates the impact response and tolerance of shipborne equipment in the impact environment.

Abstract

This application relates to a lifting mechanism and an impact testing device. The impact testing device includes a load frame and a lifting mechanism. The lifting mechanism includes a frame, a drive source, and a lifting assembly. The drive source is mounted on the frame. The lifting assembly includes a first boom and a release device connected to one end of the first boom. The end of the first boom away from the release device is rotatably connected to the frame. The release device is connected to the drive source. The lifting mechanism also includes a second boom, one end of which is rotatably connected to the frame, and the other end of which is rotatably connected to the load frame. The first boom and the second boom are arranged in parallel. This allows the release device and the load frame to move together along the same arc trajectory. After the release device disengages from the load frame, the load frame continues to fall along the aforementioned arc trajectory under the traction of the second boom. This ensures that the base, elastically connected to the load frame, maintains a consistent impact point each time it is impacted, thus realistically simulating the inherent characteristics of a ship's deck.
