Hydraulic mine safety door

Abstract

The invention discloses a hydraulic mine safety door and belongs to the technical field of safety doors. The hydraulic mine safety door comprises a base, door columns, a hydraulic cylinder, a hydraulic controller, a hydraulic rod, a supporting rod and a door body. The bottom faces of the door columns and the hydraulic cylinder are arranged on the base, rising and falling of the hydraulic rod are controlled through the hydraulic controller, and the upper end face of the hydraulic rod is in rigid connection with the supporting rod. The door body is arranged between the two door columns, and thesupporting rod and the door body are arranged into a whole. By adoption of the hydraulic mine safety door, the hydraulic safety door is opened in an up-down mode, thus the needed operation space is very small, a dual insurance mechanism is further arranged, the safety accidents can be effectively reduced, and the hydraulic mine safety door is simple in structure, convenient to repair and rapid inrepair so that the later-period maintenance cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of safety doors, in particular to a hydraulic mine safety door. Background technique [0002] The mine is a very important channel for transporting personnel and materials. In the process of transportation, in order to ensure safety, it is necessary to install a wellhead safety door at the wellhead. In the past, the wellhead safety door used a split-type safety door, and often closed asymmetrically, or the bearing broke and so on. , can not achieve the effect of protecting the mine mouth, because the way of opening the door needs to provide a large safety door operating space, because the damage rate of the mine mouth safety door is high during the use process, the maintenance cost is high, and the production is seriously affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic mine safety door which is safe and convenient to use at ...
