Description

Technical Field

[0001] This utility model relates to the field of mining hydraulic press technology, and in particular to a combined and fixed support type mining hydraulic support structure. Background Technology

[0002] On a mining hydraulic press, a support plate is installed to support objects used in mining construction. Generally, the support plate is located on the top of the hydraulic press. This support structure is the support plate assembled on the top of the hydraulic press.

[0003] The top support plate of a mining hydraulic press generally has a simple structure, being a rectangular plate with a fixed support area and fixed support node positions. When providing support, the support range is limited and cannot adapt to different environments or uneven support components, making it difficult to meet different support and load-bearing requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a combined and solidified hydraulic support structure for mining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The combined support type hydraulic support structure for mining includes a rectangular support plate. The support plate has a pair of openings near the top side wall, and a pair of concave-shaped connecting frames are movably connected within the openings.

[0007] Preferably, the end wall of the connecting frame is threaded with a screw rod, and the end wall of the screw rod is intermittently fixed with five rectangular blocks.

[0008] Preferably, the end wall of the solid block is provided with a screw hole, and a vertical rod is threaded into the screw hole.

[0009] Preferably, the end wall of the upright rod is threaded with a screw seat, and the top wall of the upright rod is fixed with a disc-shaped top plate.

[0010] Preferably, the support plate has a threaded hole near the edge end wall, and a screw that is threadedly connected to the connecting frame is threaded into the threaded hole.

[0011] Preferably, the support plate has screw holes equidistantly provided on both the left and right walls.

[0012] This utility model has at least the following beneficial effects:

[0013] At the two sides of the support plate, a pair of connecting frames are movably connected. The connecting frames can move laterally and change position, extending out from the side of the support plate. At this time, the top of the connecting frames can also be used to support objects, increasing the support range of the entire structure. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a combined and solidified hydraulic support structure for mines:

[0022] like Figure 1-4 As shown, the combined support type mining hydraulic support structure includes a rectangular support plate 1. The support plate 1 has a pair of side openings 2 near the top side wall. A pair of concave-shaped connecting frames 4 are movably connected inside the side openings 2.

[0023] The end wall of the connecting frame 4 is threaded with a screw rod 5, and the end wall of the screw rod 5 is intermittently fixed with five rectangular blocks 6. The end wall of the blocks 6 is provided with a screw assembly hole 7, and the screw assembly hole 7 is threaded with a vertical rod 8.

[0024] The end wall of the upright rod 8 is threaded with a screw seat 9, and the top wall of the upright rod 8 is fixed with a disc-shaped top plate 10. The support plate 1 has a threaded hole 3 near the end wall of the edge 2. The threaded hole 3 is threaded with a screw 11 that is threaded with the connecting frame 4. The left and right walls of the support plate 1 are equally spaced with screw holes 12.

[0025] Working principle:

[0026] Support plate 1 is set on the top of the mining hydraulic press and connected to the hydraulic cylinder. It moves upward by transmission and is used to support objects in mining construction.

[0027] At the two side openings 2 of the support plate 1, a pair of connecting frames 4 are movably connected. The connecting frames 4 can move laterally and change their position, extending out from the side of the support plate 1. At this time, the top of the connecting frames 4 can also be used to support objects, increasing the support range of the entire structure.

[0028] Four screws 5 are connected to the connecting frame 4. The screws 5 rotate and move laterally to change their position. At this time, the upright rods 8, which are connected to the fixed blocks 6 intermittently set on the screws 5 through the screw holes 7, change their height when they rotate. The top plate 10 on the top wall of the upright rod 8 is used to support small support components. The position of the top plate 10 is controllable and adjustable to adapt to different support requirements. The screw seat 9 rotates and moves along the vertical direction of the upright rod 8. After the screw seat 9 moves down, its lower wall is connected to the upper wall of the fixed block 6 to form a support, making the upright rod 8 more resistant to load.

[0029] Tighten screw 11 and insert it into threaded hole 3 to lock and limit the position of connecting frame 4 after adjustment;

[0030] The screw 5 rotates and passes into the screw hole 12 on the side wall of the support plate 1, so that the screw 5, the support plate 1, and the connecting frame 4 are firmly connected together to form an integrated and stable support structure.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
