Lifting cage safety protection door for material elevator

Abstract

The invention discloses a lifting cage safety protection door for a material elevator. The protection door comprises a lifting frame, a lifting cage body, a large front door and a small front door; the lifting frame is arranged behind the lifting cage body, the lifting cage body is of a rectangular box body structure without the upper surface and the front side surface, the lifting cage body is lifted to the rectangular box body structure without the upper surface and the front side surface, the large front door is arranged on the front side surface of the lifting cage body in a sealed manner,a top seal plate is sealed on the upper surface of the lifting cage body, the length and the width of the top seal plate are larger than the length and the width of the bottom face of the lifting cage body, the bottom faces of the two ends of the top seal plate are supported through supporting foot frames on supporting rods, the height of the supporting rods is two times that of the lifting cagebody, when the lifting cage body falls to the ground, the supporting foot frames on the supporting rods support the top seal plate and the large front door to be automatically opened, and when a protection door of the lifting cage body is on the bottom plate, opening is more convenient.

Description

technical field [0001] The invention relates to the technical field of material hoists, in particular to a safety protection door for a hanging cage for a material hoist. Background technique [0002] The material hoist is a mechanical conveying device with a fixed device. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It is equipped with broken rope protection safety devices, parking safety devices, buffer devices, upper and lower heights and limit limits However, it still has the following disadvantages in actual use: [0003] 1. In the existing technology, the protective door of the material hoist is often inconvenient to use during actual use, and the safety protection is low; [0004] 2. In the prior art, the protective door of the material hoist is often opened by manual or manual control, which is inconvenient to use and low in efficiency. [0005] For this reason, we have proposed a kind of cage safety prot...
