Description

Technical Field

[0001] This invention relates to the field of coal mine tunneling support equipment technology, specifically a multi-functional support equipment for the roof of a re-mining tunnel. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is usually stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mine tunneling machines are machines used to excavate tunnels in flat ground. Coal mine tunneling is a relatively dangerous job. During coal mine tunneling, support devices are needed to protect workers and prevent objects from falling and causing injury.

[0003] There are many types of support devices on the market today, which can basically meet people's needs. However, there are still some shortcomings. The existing support devices are generally not easy to adjust in height during use, which makes it difficult for the devices to adapt to coal mines of different heights and has certain limitations. Therefore, it is urgent to improve them. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional roof support equipment for a mining tunnel, comprising a lower support column, an upper support column, a crossbeam, a T-beam, and a protective plate. The upper support column is positioned above the lower support column. A drive groove is provided at the top of the lower support column, and a telescopic drive component is installed inside the drive groove. The output end of the telescopic drive component is fixedly connected to the bottom end of the upper support column. Positioning cylinders are fixed on both sides of the lower support column, and guide rods are provided inside the positioning cylinders. The guide rods are slidably connected to the positioning cylinders, and the top ends of the guide rods extend above the positioning cylinders and are fixedly connected to the bottom end of the upper support column. The crossbeam is welded to the top of the upper support column, and the T-beam is welded to the center position at the top of the crossbeam. The protective plate is positioned on both sides of the T-beam, and the top end of the protective plate is welded to the T-beam. The bottom end of the protective plate is welded to the upper support column. A guide plate is fixed on one side of the top of the upper support column, and a positioning mechanism is provided on one side of the bottom end of the lower support column.

[0006] Preferably, the bottom end of the lower support column is equipped with casters to facilitate the movement of the device.

[0007] Preferably, diagonal bracing is provided between the crossbeam and the protective plate, and the top and bottom ends of the diagonal bracing are connected to the protective plate and the crossbeam by positioning bolts. Furthermore, support rods are welded inside the diagonal bracing to provide diagonal support for the protective plate. The diagonal bracing and support rods work together to form a triangular structure, which enhances the load-bearing capacity of the protective plate.

[0008] Preferably, the upper surface of the T-beam is adhered with rubber strips, and the protective plates on both sides of the T-beam are adhered with rubber pads, which can buffer falling objects, reduce impact force and noise.

[0009] Preferably, the positioning mechanism is provided with a horizontal plate, a threaded hole, a threaded post, a handle, and a positioning support foot in sequence inside. A horizontal plate is fixed on the outer wall of the bottom of the lower support, and the horizontal plate is provided with a threaded hole inside to facilitate the fixing of the threaded post.

[0010] Preferably, the threaded hole is provided with a threaded post inside, the threaded post is threadedly connected to the threaded hole, and the top end of the threaded post extends to the top of the horizontal plate and is equipped with a handle, and the bottom end of the threaded post extends to the bottom of the horizontal plate and is fixed with a positioning support foot, so as to facilitate the positioning of the device.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the multi-functional roof support equipment for re-mining roadways not only facilitates height adjustment of the device to adapt to coal mine tunneling operations at different heights, improving pressure resistance and device stability, but also facilitates movement, increasing flexibility during use; specifically, it also includes the following: This technical solution includes a drive groove, a telescopic drive component, a guide rod, and a positioning cylinder. Activating the telescopic drive component causes the upper support column to move upwards, raising the entire device. During this upward movement, the upper support column drives the guide rod to move synchronously upwards within the positioning cylinder. The cooperation between the guide rod and the positioning cylinder makes the height adjustment of the device more stable, thus facilitating height adjustment to adapt to coal mine tunneling operations at different heights.

[0012] This technical solution incorporates a crossbeam, a T-beam, diagonal braces, support rods, and positioning bolts. The crossbeam and T-beam support the overall structure of the device, while the diagonal braces provide diagonal support for the protective plate. The diagonal braces and support rods work together to form a triangular structure, enhancing the load-bearing capacity of the protective plate and thus improving its pressure resistance and the stability of the device.

[0013] This technical solution includes a moving wheel, a horizontal plate, a threaded hole, a threaded column, a handle, and a positioning foot. The device is moved by the moving wheel, which can adjust the placement of the device. Then, by rotating the threaded column with the handle, it rotates and moves downward in the threaded hole inside the horizontal plate. The threaded column drives the positioning foot to move down to the ground, thus positioning the device. This makes the device easy to move and improves the flexibility of use.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 The present invention provides an embodiment of a multi-functional support equipment for the roof of a mining tunnel, comprising a lower support column 1, an upper support column 3, a crossbeam 4, a T-beam 5, and a protective plate 7. The upper support column 3 is positioned above the lower support column 1. A drive groove 11 is provided at the top of the lower support column 1, and a telescopic drive component 12 is installed inside the drive groove 11. The output end of the telescopic drive component 12 is fixedly connected to the bottom end of the upper support column 3. Positioning cylinders 14 are fixed on both sides of the lower support column 1, and guide rods 13 are provided inside the positioning cylinders 14. The guide rods 13 are slidably connected to the positioning cylinders 14, and the top end of the guide rods 13 extends above the positioning cylinders 14 and is fixedly connected to the bottom end of the upper support column 3. A movable wheel 2 is installed at the bottom end of the lower support column 1 to facilitate the movement of the device.

[0021] The crossbeam 4 is welded to the top of the upper support column 3; the T-beam 5 is welded to the center of the top of the crossbeam 4; the protective plate 7 is set on both sides of the T-beam 5, and the top of the protective plate 7 is welded to the T-beam 5, and the bottom of the protective plate 7 is welded to the upper support column 3.

[0022] A diagonal brace 15 is provided between the crossbeam 4 and the protective plate 7. The top and bottom ends of the diagonal brace 15 are connected to the protective plate 7 and the crossbeam 4 by positioning bolts 17. A support rod 16 is welded inside the diagonal brace 15 to provide diagonal support for the protective plate 7. The diagonal brace 15 and the support rod 16 cooperate to form a triangular structure, which enhances the load-bearing capacity of the protective plate 7.

[0023] Rubber strips 6 are glued to the upper surface of the T-beam 5, and rubber pads 8 are glued to the surface of the protective plates 7 on both sides of the T-beam 5, which can buffer falling objects, reduce impact force and noise; a guide plate 9 is fixed to one side of the top of the upper support 3; a positioning mechanism 10 is provided on one side of the bottom of the lower support 1.

[0024] The positioning mechanism 10 is provided with a horizontal plate 1001, a threaded hole 1002, a threaded post 1003, a handle 1004, and a positioning support 1005 in sequence. The horizontal plate 1001 is fixed on the outer wall of the bottom of the lower support column 1, and the threaded hole 1002 is provided inside the horizontal plate 1001.

[0025] A threaded post 1003 is provided inside the threaded hole 1002. The threaded post 1003 is threadedly connected to the threaded hole 1002. The top end of the threaded post 1003 extends to the top of the horizontal plate 1001 and is equipped with a handle 1004. The bottom end of the threaded post 1003 extends to the bottom of the horizontal plate 1001 and is fixed with a positioning foot 1005. By rotating the threaded post 1003 with the handle 1004, it rotates and moves downward in the threaded hole 1002 inside the horizontal plate 1001. The threaded post 1003 drives the positioning foot 1005 to move down to the ground, thereby positioning the device.

[0026] When this equipment is in use, the telescopic drive component 12 is activated first to drive the upper support column 3 to move upward. The upward movement of the upper support column 3 raises the entire device. During the upward movement of the upper support column 3, the guide rod 13 is driven to move upward synchronously inside the positioning cylinder 14. The cooperation between the guide rod 13 and the positioning cylinder 14 makes the height adjustment of the device more stable, thus facilitating the height adjustment of the device to adapt to coal mine tunneling work at different heights.

[0027] During coal mine tunneling, the protective plate 7 blocks falling objects, which are then discharged through the guide plate 9. The rubber strips 6 and rubber pads 8 cushion the falling objects, reducing impact force and noise. The crossbeams 4 and T-beams 5 support the overall structure of the device, while the diagonal bracing 15 provides diagonal support for the protective plate 7. The diagonal bracing 15 and the support rods 16 work together to form a triangular structure, enhancing the load-bearing capacity of the protective plate 7 and thus improving its pressure resistance and the stability of the device.

[0028] The pusher moves the device under the action of the moving wheel 2, which can adjust the placement of the device. Then, the threaded column 1003 is rotated by the handle 1004 so that it rotates and moves down in the threaded hole 1002 inside the horizontal plate 1001. The threaded column 1003 drives the positioning support 1005 to move down to the ground, which can position the device, making it easy to move and improving the flexibility of use, thus completing the work of multi-functional support equipment for the roof of the mining tunnel.
