[0002] Mining engineering is primarily the engineering and technological science used to guide the safe, efficient, and environmentally friendly mining of mineral resources, as well as the effective processing and utilization of mineral resources. During underground operations, safety is paramount. To prevent mine collapses during construction, workers install support frames to reinforce the mine walls.

[0003] Most existing support frames are made of wood. Wooden support frames are inconvenient to adjust, making it difficult to support different parts of the cave wall. In addition, wooden support frames are inconvenient to assemble and disassemble, making them inconvenient to use.

[0004] Therefore, there is an urgent need for a support frame for underground mining operations to solve the problem of inconvenient adjustment of the support frame. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a support frame for underground mining operations, which has the advantage of facilitating support at different locations on the tunnel wall and solves the problem of inconvenient adjustment of the support frame.

[0006] To achieve the above objectives, this application provides the following technical solution: a support frame for underground mining operations, comprising a support sleeve, a bracket, and a fixing plate, wherein the bracket is slidably connected to the top of the support sleeve, the fixing plate is disposed at the bottom of the support sleeve, an adjustment mechanism is provided on the bracket, and fixing mechanisms are provided on both sides of the support sleeve;

[0007] The adjustment mechanism includes a connecting sleeve, a support rod, a pressure block, and a second fixing plate. The connecting sleeve is slidably connected to the end of the bracket away from the support sleeve. The support rod is located on one side of the bracket. The pressure block is threaded to the outer surface of the support rod. The second fixing plate is welded to both sides of the connecting sleeve.

[0008] By adjusting the height and length of the support frame, it can be easily supported at different positions inside the underground working tunnel wall when installed in mining engineering. By supporting different positions of the underground working tunnel wall with the support frame, the strength of the underground working tunnel wall is improved.

[0009] Preferably, one side of the connecting sleeve has a sliding groove adapted to the support rod.

[0010] Preferably, a bolt body is installed on the inner side of the support sleeve, and several sets of insertion holes are opened on the inner side of the bracket at positions corresponding to the bolt body.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-4 A support frame for underground mining operations includes a support sleeve 1, a bracket 2, and a fixing plate 3. The bracket 2 is slidably connected to the top of the support sleeve 1, and one end of the bracket 2 is inserted into a slot at the top of the support sleeve 1. The bracket 2 can slide in a slot on the inner side of the support sleeve 1. The fixing plate 3 is located at the bottom of the support sleeve 1 and the fixing plate 3 fixes the support sleeve 1 to the ground by bolts. The bracket 2 is provided with an adjustment mechanism, and the support sleeve 1 is provided with fixing mechanisms on both sides.

[0024] Specifically, the adjustment mechanism includes a connecting sleeve 111, a support rod 112, a pressure block 113, and a fixing plate 115. The connecting sleeve 111 is slidably connected to the end of the bracket 2 away from the support sleeve 1. The support rod 112 is located on one side of the bracket 2. The pressure block 113 is threaded to the outer surface of the support rod 112. The fixing plate 115 is welded to both sides of the connecting sleeve 111. A sliding groove 114 adapted to the support rod 112 is opened on one side of the connecting sleeve 111. A connecting block 118 is welded between the two sets of connecting sleeves 111. A bolt body 116 is installed inside the support sleeve 1. Several sets of insertion holes 117 are opened inside the bracket 2 at positions corresponding to the bolt body 116.

[0025] Through the above technical solution, during the assembly of the support frame, one end of the bracket 2 is inserted into the top of the support sleeve 1. The bracket 2 is pulled to a suitable position, thus adjusting the height of the support frame. The worker passes the bolt body 116 through the support sleeve 1 and connects it to the insertion hole 117, thereby fixing the bracket 2. At the same time, the worker pulls the bracket 2, and the bracket 2 slides inside the connecting sleeve 111. When the bracket 2 moves to a suitable position inside the connecting sleeve 111, the worker rotates the pressure block 113. When the pressure block 113 moves on the outer surface of the support rod 112, it presses against one side of the connecting sleeve 111, thereby fixing the position of the bracket 2. By adjusting the position of the bracket 2, the width of the support frame can be changed. By adjusting the height and length of the support frame, when the support frame is installed inside the underground working hole wall of the mining project, it can be conveniently supported at different positions inside the underground working hole wall. By supporting different positions of the underground working hole wall with the support frame, the strength of the underground working hole wall is improved, making the use of the underground working hole wall safer.

[0026] The fixing piece 115 is fixed to the top of the hole wall by bolts. When disassembling the support frame, the workers remove the bolt body 116 and pull the bracket 2 out of the support sleeve 1, thereby separating the support sleeve 1 from the bracket 2 and making the support frame easy to disassemble.

[0027] Specifically, the fixing mechanism includes a fixing plate 211, a fixing rod 212, a baffle 213, and a card 214. The fixing plate 211 is welded to both sides of the support sleeve 1. The fixing rod 212 passes through the fixing plate 211 and is inserted into the hole wall. The baffle 213 is welded to the outer surface of one end of the fixing rod 212. The card 214 is welded to the outer surface of the fixing rod 212. A pressure groove 215 is provided on the outer surface of the fixing rod 212 at the position corresponding to the card 214.

[0028] Through the above technical solution, when the support sleeve 1 is fixed to the tunnel wall, the fixing rod 212 passes through the fixing plate 211 and is fixed to the tunnel wall, and the clip 214 is stuck inside the tunnel wall, so that the support sleeve 1 can be stably fixed to the tunnel wall, so that the support frame can be stably installed and the overall stability of the support frame can be improved.

[0029] When the fixing rod 212 passes through the fixing plate 211, the card 214 is pressed into the pressure groove 215, allowing the fixing rod 212 to pass through the fixing plate 211 easily. The card 214 has a certain degree of elasticity.

[0030] When in use, the height and length of the support frame can be adjusted so that when the support frame is installed inside the tunnel wall of the mining project, it can be easily supported at different positions inside the tunnel wall. By supporting different positions of the tunnel wall, the strength of the tunnel wall is improved, making the use of the tunnel wall safer.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
