Abstract

The invention relates to a lift car for a dredger with a buffering device, and belongs to the technical field of lifts. The lift car for the dredger with the buffering device is simple in structure. When in use, the pressure borne by the inner box of a lift is transmitted to an elastic medium layer through a supporting plate, the supporting plate slides upwards or downwards in a cabinet body, andthe elastic medium layer is stressed with pressure to form elastic potential used as buffering power so as to reduce the pressure stressed by the inner box. When the supporting plate goes down to theposition of a cam, the inner box is prevented from going on to move downwards. It can be effectively avoided that passengers panic because the inner box goes down for too much. Also, it is reduced that because an inner box goes down for too much, the inner box cannot return to the original position in time after a lift stops, and unwanted safety accidents are caused further after the door of the lift opens.

Description

technical field [0001] The invention relates to an elevator car for a dredger with a buffer device, and belongs to the technical field of elevators. Background technique [0002] Some high-end dredgers are equipped with elevators. When the elevator goes up, people are overweight, which will greatly increase the damage to the bottom of the inner box and cause discomfort to the passengers. [0003] A cushioning device for an elevator car disclosed in the application number 201620219746.6, including a guide sleeve upper seat, a buffer pad, a guide sleeve, a guide post, a guide post base, a spring, a support plate, an inner box, a sound insulation board, a shock pad and a box body. The column base is installed on the inner bottom of the box. The bottom surface of the guide column is installed on the upper surface of the guide column base. The spring is slidingly connected with the guide column. The guide column is slidingly connected with the guide sleeve. The bottom surface of...
