Description

Technical Field

[0001] The invention belongs to the technical field of mining engineering, and in particular relates to a safety protection frame for supporting a cave wall of an underground mining engineering operation. Background Art

[0002] The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. It refers to the method of extracting ores from the mining area, which includes three tasks: mining, cutting and recovery. The mining work is arranged according to the size of the constituent elements of the ore block, and solves the problems of pedestrians, ore transportation, equipment and material transportation, ventilation and communication for the recovery of the ore block. Cutting creates the necessary free surface and ore falling space for recovery. After these two tasks are completed, large-scale recovery can be carried out directly. These three tasks are all carried out within a certain time and space. These three tasks are linked together and organically coordinated in time and space in turn. Due to the very complex occurrence conditions of metal ore deposits, the properties of ore and surrounding rock are changing, and with the development of science and technology, new equipment and materials are constantly emerging, new processes are becoming more and more perfect, and some old mining methods with low efficiency and high labor intensity are gradually being eliminated.

[0003] The currently used safety protection frame drives the screw to rotate by turning the knob to adjust the distance between the top plate and the column, then slides the guide block to adjust the horizontal position of the column, uses the arc-shaped plug rod to fix the guide block, then rotates the column to adjust the direction of the mounting plate, and uses the locking rod to fix the column. The limit block is set to prevent the screw from falling off the threaded sleeve.

[0050] In one example of the present invention, when the longitudinal column 13 is subjected to the force of the top plate 2, the longitudinal columns 13 at multiple positions slide along the annular base 14, and the longitudinal columns 13 at the corresponding positions push the inner rocker rod 15 to make a plane swing in the annular base 14, and the bottom end of the rocker rod 15 slides along the groove opened on the annular base 14 and applies a force to the corresponding elastic support member 3 16, and the elastic support member 3 16 undergoes elastic deformation under the force.

At the same time, the bolt 24 uses a self-locking nut to facilitate the arc plate 21 to slide along the top plate 2, the annular base 14 and the horizontal plate 26 when subjected to external force. In the process of moving with the longitudinal column 22, the bolt 24 applies a force to the elastic support members 25 on both sides, and the elastic support members 25 at the corresponding position are elastically deformed under the force.

At this time, the elastic support member 12 installed in the bracket 9 is elastically deformed and matched with a damper to offset the force on the side. When the top of the cave wall in the mining industry has an arc, the arc plate 21 and the longitudinal column 22 are inserted downward along the top plate 2. When the bottom end of the longitudinal column 22 is between the annular base 14 and the horizontal plate 26, the bolt 24 is screwed on the threaded portion 23, and elastic support members 25 are arranged on both sides of the bolt 24. At the same time, the bolt 24 uses a self-locking nut to facilitate the arc plate 21 to move along the top when it is subjected to external force.
