DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0025] The following will describe an auxiliary support device for coal mine roadway tunneling according to an embodiment of the present utility model with reference to the accompanying drawings.

[0026] As Figures 1 - 4 shown, an auxiliary support device for coal mine roadway tunneling according to an embodiment of the present utility model includes a bottom plate 1, a mounting plate 2, a lifting device 3, and a support device 4. Among them, the mounting plate 2 is disposed on one side of the bottom plate 1. The lifting device 3 includes a driving component 31 and a connecting component 32. Among them, the driving component 31 is disposed on the bottom plate 1, and the connecting component 32 is slidably disposed on the mounting plate 2 and is connected to the driving component 31. The support device 4 includes a support plate 41 and a support component 42. Among them, the support plate 41 is disposed on the connecting component 32, and the support component 42 is disposed on the support plate 41.

[0027] It can be understood that the driving component 31 rotates to drive the connecting component 32 to slide up and down on the mounting plate 2. When the connecting component 32 slides on the mounting plate 2, it synchronously drives the support plate 41 and the support component 42 to slide up and down. Therefore, it is possible to quickly and stably adjust the height, greatly improving the operation efficiency and flexibility. At the same time, a buffer component is provided in the support component 42, which not only ensures the stability during the support process but also effectively reduces the impact and vibration of the device under complex geological conditions, thereby extending the service life of the equipment.

[0028] In an embodiment of the present utility model, as Figure 4As shown in the figure, the driving component 31 includes a driving motor 311, a base 312, a connecting rod 313, a rotating shaft 314, two bearing seats 315, a sliding frame 316, a threaded rod 317, and two first racks 318. Among them, the driving motor 311 is arranged on the bottom plate 1, the base 312 is arranged on the bottom plate 1, and the base 312 is connected to the bottom of the driving motor 311. The connecting rod 313 is connected to the output end of the driving motor 311. The rotating shaft 314 is connected to one end of the connecting rod 313. The two bearing seats 315 are arranged on the bottom plate 1, and the rotating shaft 314 is rotatably arranged between the two bearing seats 315. The sliding frame 316 is arranged on the bottom plate 1. The threaded rod 317 is rotatably arranged in the sliding frame 316, and the threaded rod 317 is threadedly connected to the side wall of the sliding frame 316. The two first racks 318 are slidably arranged on both sides of the sliding frame 316 in opposite directions, and one of the two first racks 318 is respectively connected to the threaded rod 317.

[0029] It can be understood that the driving motor 311 rotates to drive the connecting rod 313 to rotate. When the connecting rod 313 rotates, it drives the rotating shaft 314 to rotate in the two bearing seats 315. When the rotating shaft 314 rotates, it drives the threaded rod 317 to rotate synchronously. When the threaded rod 317 rotates, the threaded rod 317 slides in the sliding frame 316. When the threaded rod 317 slides, it drives one of the two first racks 318 to slide outwards synchronously.

[0030] It should be noted that the driving motor 311 described in this embodiment is a bidirectional motor. Therefore, it can drive the rotating shaft 314 to rotate in different directions, and at the same time, the threaded rod 317 can perform threaded sliding in different directions on the sliding frame 316.

[0031] In an embodiment of the present invention, as Figure 2 shown, the connecting component 32 includes a connecting plate 321, a gear plate 322, two second racks 323, four gears 324, and four connecting rods 325. Among them, the connecting plate 321 is slidably arranged on one side of the mounting plate 2, and the connecting plate 321 is connected to the support plate 41. The gear plate 322 is arranged on one side of the connecting plate 321. The two second racks 323 are respectively arranged at both ends of the gear plate 322 in opposite directions. The four gears 324 are respectively meshed with the two first racks 318 and the two second racks 323. The four connecting rods 325 are connected in pairs and movably, and the other ends of the four connecting rods 325 are respectively connected to the four gears 324.

[0032] It can be understood that when one of the two first racks 318 slides outwards, it will drive one of the four gears 324 to rotate on the rack, and at the same time drive two of the four link rods 325 that are movably connected to move. Therefore, it can drive the four gears 324 to slide on the two first racks 318 and the two second racks 323. When the two gears 324 located below slide inwards synchronously on the two first racks 318, it will drive the two gears 324 located above to slide outwards synchronously on the two second racks 323. Therefore, it can drive the four link rods 325 to gradually rise, and at the same time drive the connecting plate 321 to slide on the mounting plate 2. Therefore, the lifting function can be realized.

[0033] In an embodiment of the present invention, as Figure 1 shown, the support assembly 42 includes three support columns 421, a first arc-shaped support plate 422, multiple groups of buffer springs 423, and a second arc-shaped support plate 424. Among them, the three support columns 421 are arranged on the top of the support plate 41, the first arc-shaped support plate 422 is arranged on the top of the three support columns 421, multiple groups of buffer springs 423 are respectively equidistantly distributed on the top of the first arc-shaped support plate 422, and the second arc-shaped support plate 424 is arranged on the top of the multiple groups of buffer springs 423.

[0034] It can be understood that the second arc-shaped support plate 424 is in contact with the top of the coal mine roadway, and the multiple groups of buffer springs 423 can buffer the pressure received. At the same time, a first arc-shaped support plate 422 is arranged at the lower end of the multiple groups of buffer springs 423, which can play a double-layer support insurance to ensure safety during the support process.

[0035] In an embodiment of the present invention, as Figure 2 shown, a protective plate 11 is arranged on the bottom plate 1, and the protective plate 11 is arranged directly above the sliding frame 316.

[0036] It can be understood that the arrangement of the protective plate 11 can provide safety protection for the driving part of the device and ensure the smoothness of the support operation.

[0037] Specifically, during the actual execution process, the driving motor 311 rotates to drive the connecting rod 313 to rotate. When the connecting rod 313 rotates, it drives the rotating shaft 314 to rotate in the two bearing seats 315. When the rotating shaft 314 rotates, it drives the threaded rod 317 to rotate synchronously. When the threaded rod 317 rotates, the threaded rod 317 slides in the sliding frame 316. When the threaded rod 317 slides, it drives one of the two first racks 318 to slide outwards synchronously.

[0038] When one of the two first racks 318 slides outward, it will drive one of the four gears 324 to rotate on the rack, and at the same time drive two of the four link rods 325 that are movably connected to move. Therefore, it can drive the four gears 324 to slide on the two first racks 318 and the two second racks 323. When the two gears 324 located below slide inward synchronously on the two first racks 318, it will drive the two gears 324 located above to slide outward synchronously on the two second racks 323. Therefore, it can drive the four link rods 325 to gradually rise, and at the same time drive the connecting plate 321 to slide on the mounting plate 2. Therefore, the lifting function can be realized.

[0039] By contacting the top of the coal mine roadway through the second arc-shaped support plate 424, the pressure received can be buffered by multiple groups of buffer springs 423. At the same time, a first arc-shaped support plate 422 is provided at the lower end of the multiple groups of buffer springs 423, which can play a double-layer support insurance to ensure safety during the support process.

[0040] In summary, an auxiliary support device for coal mine roadway tunneling in the embodiment of the present utility model is provided with a lifting device, which can accurately respond to the requirements of different roadway heights, realize rapid and stable height adjustment, greatly improve the operation efficiency and flexibility. At the same time, it is also provided with a buffer support device, which not only ensures the stability during the support process, but also effectively reduces the impact and vibration of the device under complex geological conditions, thereby extending the service life of the equipment and maximizing the protection of the safety of the device itself and its surrounding environment.
