Problems solved by technology

At present, the opening and closing of the wellhead safety doors of metal mines in my country is mostly manual operation, which is not conducive to safe production
[0003] The traditional safety door is an electric wire rope traction type safety door that moves up and down. It is manually operated and has the following disadvantages in the process of use: the wire rope is seriously worn and needs to be replaced frequently; the safety door is easy to tilt and get stuck during operation, causing overall deformation and affecting the use and appearance; Manual operation of opening and closing the door is prone to errors; when the door is opened and closed in place, it will produce a large impact, which shortens the service life of the safety door; moreover, when transporting long materials or large-scale equipment, it is necessary to remove the safety door to complete the transportation. work brings great inconvenience

Embodiment Construction

[0020] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 , figure 2 and image 3 As shown, the safety door includes two square door bodies 1 that cooperate to open and close. The door body 1 is hinged on the door post 2 through four bearings 4. The door body 1 is provided with two buffer blocks 3. After the door body 1 is closed, The buffer block 3 can buffer the impact force when the door body 1 is closed, protect the door body 1, and reduce wear; the buffer pad and the buffer pad plate are combined into the buffer block 3 by hexagon socket bolts; A hydraulic system controlled by a PLC module. The hydraulic system includes a rack cylinder 6 that controls the opening and closing of the door body 1. The rack cylinder 6 is connected to the door body 1 through a coupling 8, wherein the rack cylinder 6 and the coupling 8 A transition shaft 7 is provided, and the hydraulic system is fi...

Abstract

The invention discloses a safety gate and belongs to the technical field of mine caging. The safety gate comprises two gate bodies which are matched with each other in opening and closing. The gate bodies are respectively hinged on a gate post through bearings. Each bearing comprises a bearing block and a bearing block base which are matched in use. A hydraulic system controlling the gate bodies to be opened and closed is respectively arranged between each gate body and the corresponding gate post. Each hydraulic system controlled by a programmable logic controller (PLC) module comprises a rack oil cylinder and a coupler which are mutually connected and each coupler is connected with the corresponding gate body. The safety gate is reasonable and compact in structure, easy to maintain and repair, capable of achieving automatic control operation, avoiding fault caused by manual operation, facilitating transportation of materials and devices large in length or size, shortening a transporting cycle and improving transporting capability and suitable for being popularized and used in production operation.

Description

technical field [0001] The invention belongs to the technical field of mine cages, and in particular relates to a safety door. Background technique [0002] In my country's mine production, the protection function of the auxiliary wellhead safety door is very important. At present, the opening and closing of the wellhead safety doors of metal mines in my country is mostly manual operation, which is not conducive to safe production. [0003] The traditional safety door is an electric wire rope traction type safety door that moves up and down. It is manually operated and has the following disadvantages in the process of use: the wire rope is seriously worn and needs to be replaced frequently; the safety door is easy to tilt and get stuck during operation, causing overall deformation and affecting the use and appearance; Manual operation of opening and closing the door is prone to errors; when the door is opened and closed in place, it will produce a large impact, which shorte...
