Study on Counterweight Structure with Buffer Device

Abstract At present, a buffer device is installed at the bottom of the elevator shaft to buffer the falling counterweight. When the elevator hits the buffer, the buffer absorbs or consumes the kinetic energy and potential energy of the elevator, so as to make the elevator or counterweight slow down safely until it stops. The corresponding counterweight is fixedly installed at the bottom of the elevator shaft. However, the counterweight installed at the bottom of the elevator shaft has certain disadvantages. In order to overcome the defects of the above existing technology, a counterweight structure with buffer device is studied in this paper. Compared with the prior art, the structure has the advantages of reducing construction time, high safety, simple structure, etc., and has universal popularization significance.
