Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a support device for mechanized coal mining. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by mankind since the 18th century. Since the beginning of the 21st century, coal has remained an indispensable energy source for human production and life.

[0003] During coal mining, a mine tunnel is formed, and the support device for the mine tunnel is an important guarantee for the safety of workers. Existing support devices usually have a fixed cone at the bottom that is inserted into the ground in order to make the base firm and reduce slippage. However, the ground of the mine tunnel is usually hard rock, and when it is necessary to move the support device, the fixed cone is difficult to remove after being inserted. In order to address the above problems, this application designs a support device for mechanized coal mining. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a support device for mechanized coal mining.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a support device for mechanized coal mining, comprising a support structure and two base structures. The base structure includes a fixed chassis, on which four reinforcing cones are slidably connected. The four reinforcing cones are evenly distributed, and a top block is fixed to the top of each reinforcing cone. A pulling mechanism is provided on the fixed chassis at the position of each reinforcing cone. The pulling mechanism includes a U-shaped frame and two bottom blocks. The two bottom blocks are fixed to the top of the fixed chassis and located on both sides of the reinforcing cone. The U-shaped frame is rotatably connected between the two bottom blocks. A screw is threadedly connected to the middle position of the U-shaped frame. A connecting block is fixed to one end of the screw on one side of the opening of the U-shaped frame. A rotating block is rotatably connected to the bottom end of the connecting block. Both ends of the rotating block are rotatably connected to locking blocks. The other end of the screw passes through the U-shaped frame and is fixed with a hexagonal slotted rotating head. A locking mechanism is provided at the top of the fixed chassis at the position of each reinforcing cone.

[0008] Furthermore, the present invention is improved in that the support structure includes a top frame and two cylinder lifting columns, the two cylinder lifting columns are respectively fixed to the top of two fixed chassis, the top of the cylinder lifting columns is fixed with a mounting block, and the top frame is fixed to the two mounting blocks by bolts.

[0009] To prevent loosening between the reinforcing cone and the fixed base, this utility model improves upon the following: the locking mechanism includes a locking cover and two defective pipe walls. The central axes of the two defective pipe walls coincide, and the two defective pipe walls are fixed to the top of the fixed base and located on both sides of the reinforcing cone. The radius of the defective pipe wall is the same as the radius of the reinforcing cone. The outer wall of the defective pipe wall is provided with threads, and the locking cover is threadedly connected to the two defective pipe walls.

[0010] To prevent slippage during rotation, the present invention is improved by providing an anti-slip groove on the outer wall of the locking cover.

[0011] To prevent the locking blocks from disengaging, this invention includes an improvement where a spring is fixed between the two locking blocks.

[0012] In order to ensure that the U-shaped frame can be in a vertical state, the present invention is improved by fixing a blocking plate on one side of the base block.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a support device for mechanized coal mining, which has the following beneficial effects:

[0015] This mechanized coal mining support device features a reinforcing cone that slides between itself and a fixed chassis. When the fixed chassis is anchored to a hard surface, the reinforcing cone is hammered with a tool to secure it firmly, effectively preventing damage to the chassis. A pulling mechanism, through the coordinated action of a locking block, a rotating block, a connecting block, and a screw, engages the locking block with the top block at the tip of the reinforcing cone. The screw then allows the reinforcing cone to be easily pulled out. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A mechanized coal mining support device includes a support structure and two base structures. The base structure includes a fixed base 1, on which four reinforcing cones 2 are slidably connected and evenly distributed. A top block 3 is fixed to the top of each reinforcing cone 2. A pulling mechanism is provided on the fixed base 1 at each position of the reinforcing cone 2. The pulling mechanism includes a U-shaped frame 4 and two bottom blocks 5. The two bottom blocks 5 are fixed to the top of the fixed base 1 and located on both sides of the reinforcing cone 2. The U-shaped frame 4 is rotatably connected between the two bottom blocks 5. A screw 6 is threadedly connected to the middle position of the U-shaped frame 4. A connecting block 7 is fixed to one end of the screw 6 on the opening side of the U-shaped frame 4. A rotating block 8 is rotatably connected to the bottom end of the connecting block 7. Both ends of the rotating block 8 are rotatably connected to locking blocks 9. The other end of the screw 6 passes through the U-shaped frame 4 and is fixed with a hexagonal slotted rotating head 10. A locking mechanism is provided at the top of the fixed base 1 at each position of the reinforcing cone 2.

[0023] In use, the device is placed inside the mine tunnel, and the top frame 11 is fixed to two mounting blocks 13 with bolts. The cylinder lifting column 12 is activated to raise the top frame 11. The cylinder lifting column 12 is a mature existing technology, using a cylinder to push the top frame 11 upwards. At this point, the fixed base 1 contacts the hard ground, and the tip of the reinforcing cone 2 contacts the ground. The top block 3 is positioned at a certain height above the fixed base 1. Using a tool, the top block 3 is hammered to move the reinforcing cone 2 downwards, inserting it into the ground. The radius of the top block 3 is larger than the radius of the reinforcing cone 2. The top block 3 contacts the tops of the two damaged pipe walls 15. After hammering, the locking cover 14 is threaded onto the damaged pipe wall 15, so that the top of the top block 3 contacts the inner top wall of the locking cover 14 to prevent loosening. When it is necessary to remove the reinforcing cone 2, the locking cover 14 is removed. In the initial state, the U-shaped frame 4 lies flat on the fixed base 1. When it is necessary to remove the reinforcing cone 2, rotate the U-shaped frame 4 to make it vertical. Use an external tool to rotate the hexagonal slot head 10, which drives the screw 6 to rotate. The screw 6 is threadedly connected to the U-shaped frame 4, so the screw 6 drives the connecting block 7 and the rotating block 8 to move up and down, so that the locking block 9 on the rotating block 8 approaches the top block 3. There is a stepped surface between the top block 3 and the reinforcing cone 2, and the locking block 9 can engage with this stepped surface. At the same time, the spring 16 restricts the two locking blocks 9 to prevent them from loosening and disengaging from the top block 3. Then, use an external tool to rotate the hexagonal slot head 10 to make the screw 6 rotate, so that the connecting block 7 drives the rotating block 8 to move upward. At this time, the two rotate relative to each other. The rotating block 8 drives the locking block 9, the top block 3 and the reinforcing cone 2 to move upward, lift them off the ground, and complete the removal of the reinforcing cone 2.

[0024] In actual use, it was found that, further, in this embodiment, the support structure includes a top frame 11 and two cylinder lifting columns 12. The two cylinder lifting columns 12 are respectively fixed to the top of the two fixed base plates 1. The top of the cylinder lifting column 12 is fixed with a mounting block 13. The top frame 11 is fixed to the two mounting blocks 13 by bolts.

[0025] In actual use, it was found that the reinforcing cone 2 may become loose from the fixed base 1, resulting in the inability to firmly fix the fixed base 1. In order to solve the above problem, in this embodiment, the locking mechanism includes a locking cover 14 and two defective tube walls 15. The central axes of the two defective tube walls 15 coincide. The two defective tube walls 15 are fixed to the top of the fixed base 1 and are located on both sides of the reinforcing cone 2. The radius of the defective tube wall 15 is the same as the radius of the reinforcing cone 2. The outer wall of the defective tube wall 15 is provided with threads. The locking cover 14 is threadedly connected to the two defective tube walls 15.

[0026] In actual use, it was found that slippage occurs when operating the locking cover 14. To avoid the above problem, in this embodiment, an anti-slip groove is provided on the outer wall of the locking cover 14.

[0027] In actual use, it was found that the locking block 9 may wobble and detach from the top block 3. To avoid the above problem, in this embodiment, a spring 16 is fixed between the two locking blocks 9.

[0028] In actual use, it was found that when the U-shaped frame 4 is not perpendicular to the fixed base 1, the friction between the reinforcing cone 2 and the side wall of the ground will make it difficult to pull out the reinforcing cone 2. In order to solve the above problem, in this embodiment, a blocking plate 17 is fixed on one side of the base block 5.
