Abstract

The invention provides a skip bucket vertical shaft wellhead sealing maintenance platform. The skip bucket vertical shaft wellhead sealing maintenance platform comprises a main support, and further comprises two bottom sealing platforms, two middle sealing platforms and two top sealing platforms which are sequentially installed on the main support from bottom to top; and each bottom sealing platform comprises two bottom layer platform supports and two bottom layer sealing plates. According to the skip bucket vertical shaft wellhead sealing maintenance platform, a hydraulic oil cylinder can push a plurality of main platform sealing plates to oppositely move on a main platform track so that the four main platform sealing plates can be all pushed to the position above a wellhead, effective sealing protection is formed on the wellhead, foreign matters are prevented from entering the wellhead, an inner side sealing plate and an outer side sealing plate are moved to be close to a skip bucket, then positioning pins are used for fixing the inner side sealing plate and the outer side sealing plate so that a worker can stand on the inner side sealing plate and the outer side sealing plate to check and maintain the skip bucket, and the maintenance becomes simple and convenient.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a sealing maintenance platform for a skip shaft wellhead. Background technique [0002] The vertical lifting of the skip shaft is a common process mode in pit mining. With the development of technology and the continuous improvement of mining depth, in order to ensure production efficiency, the operation speed of equipment is getting faster and faster. Because the ore lifting and conveying process is a key process in the entire production process, the maintenance requirements for the skips in the main and auxiliary bucket gates are getting higher and higher, and the spot inspection of each shift is essential according to the safety management standards of mining equipment. Therefore, close inspection and quick replacement of parts are the basic conditions to ensure safe production. However, due to the limitations of the operating conditions of the skip, whether in the wellbo...
