[0002] A mine is the collective term for the shafts, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Inclined shafts, vertical shafts, and horizontal tunnels in underground mine development are sometimes also referred to as mines. Existing vertical shaft mining typically uses a mining bucket, which often requires lifting. To address this issue, we propose a rotary lifting device for a mining bucket used in vertical shaft mining.

[0003] The Chinese patent with the announcement number CN221759344U discloses a rotary adjustment lifting device for a mining bucket for vertical shaft mining, comprising: a support frame, a winding drum is provided on the support frame, a steel wire rope is wound on the winding drum, a hook 2 is fixedly provided at the bottom end of the steel wire rope, and a protective component is hung on the hook 2; the protective component comprises a hanging ring, a protective frame is fixedly provided at the bottom of the hanging ring, a plurality of rotating sleeves are rotatably provided on the protective ring of the protective frame, and a hook 1 is fixedly provided in the protective frame. During use, the friction and collision between the rotating sleeve and the well wall prevent the frame barrel on the hook 1 from directly colliding with the well wall, thereby avoiding wear of the frame barrel and being able to provide multi-directional protection for the barrel body of the ore bucket. The rotating sleeve rotates up and down, which can reduce the downward resistance generated by collision and friction with the well wall, so that the ore bucket rises more smoothly.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Example 1

[0034] like Figure 1-Figure 5 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a rotary adjustment and lifting device for a mining bucket for vertical shaft mining, including a base 1 and a support bracket 2 connected to the top thereof, a support plate 3 connected to the top of the support bracket 2, a rotating motor 4 connected to the top of the support plate 3, and a lifting threaded rod 5 connected to the bottom output end of the rotating motor 4 through the support plate 3, and the lifting threaded rod 5 is threadedly connected to the lifting plate 6 on the outer arc surface of the lifting threaded rod 5. The side of the lifting plate 6 is slidably connected to the support bracket 2, and the top of the lifting plate 6 is rotatably connected to the threaded rod 8, and the bottom of the threaded rod 8 is connected through a connecting shaft 9, and the other end of the connecting shaft 9 is connected to a docking component 10.

[0035] A through hole is provided on the top of the support plate 3 , and the threaded rod 8 passes through the through hole. The support plate 3 is provided with a threaded sleeve 7 , and the threaded sleeve 7 is threadedly connected to the threaded rod 8 .

[0036] The docking component 10 includes a rotating shell 1001 connected to the bottom of the connecting shaft 9, the bottom of the outer arc surface of the rotating shell 1001 is connected to a rotating limiter 1002, the inner arc surface of the rotating limiter 1002 is rotatably connected to a rotating disk 1003, the bottom of the rotating disk 1003 is connected to a connecting column 1004, and the end of the connecting column 1004 away from the rotating disk 1003 is connected to a docking component 1005.

[0037] The rotating disk 1003 is provided with a transmission groove 1009 , and a sliding column 1007 is slidably connected to the inner wall of the transmission groove 1009 . The bottom of the sliding column 1007 is connected to a protective member 1006 , and the protective member 1006 faces the outer arc surface of the rotating disk 1003 .

[0038] The inner wall of the rotating shell 1001 is connected to a rotating base 1010 . The rotating base 1010 is provided with a guide groove 1011 . The inner wall of the guide groove 1011 is slidably connected to the sliding post 1007 .

[0039] The specific working principle is: the protective member 1006 extending outward through this device can protect the mining bucket when the outer diameter of the outer end of the protective member 1006 is larger than the outer diameter of the mining bucket, thereby avoiding problems such as collision of the mining bucket during the rising process. Compared with traditional devices, this device adopts a slidable and adjustable protective structure that can effectively adapt to mining buckets of different sizes and mining holes of different sizes.

[0040] When the device is in use, the support bracket 2 and the support plate 3 can facilitate the installation of the device on the top of the mine. The combination of the rotating motor 4 and the lifting threaded rod 5 can drive the lifting plate 6 to slide vertically linearly on the side of the support bracket 2. The combination of the threaded rod 8 and the threaded sleeve 7 can drive the connecting shaft 9 to rotate during the vertical linear sliding of the lifting plate 6, thereby achieving the effect of rotating and rising the mining bucket and the protective member 1006, so that the outer end surface of the protective member 1006 wears more evenly during use.

[0041] The docking piece 1005 can be used to connect the device to the mining bucket, and the threaded knob 1008 can be unlocked at the same time. At this time, the rotating disk 1003 can rotate freely. By rotating the rotating disk 1003, the combination of the transmission groove 1009 and the guide groove 1011 can be used to rotate the rotating disk 1003 and simultaneously drive multiple groups of sliding columns 1007 to slide, thereby achieving the effect of simultaneously controlling multiple protective members 1006. When the rotating disk 1003 is rotated to the appropriate position, rotating the threaded knob 1008 can lock the current rotation angle of the rotating disk 1003, thereby preventing the protective member 1006 from sliding abnormally, thereby ensuring the stability of the device.

[0042] Example 2

[0043] like Figure 1-Figure 5 As shown, in order to solve the existing problems, in this embodiment, based on the same concept as the above-mentioned embodiment 1, the mining bucket rotation and lifting device for vertical shaft mining also includes: a plurality of corresponding guide grooves 1011 and transmission grooves 1009 are provided on the rotating disk 1003 and the rotating base 1010, and the rotating disk 1003 is provided with a plurality of sliding columns 1007, and the sliding columns 1007 correspond to the guide grooves 1011 and the transmission grooves 1009 one by one.

[0044] The protective member 1006 is semicircular, and the outer end surface of the protective member 1006 is provided with a wear-resistant layer. The bottom of the rotating disk 1003 is threadedly connected to a threaded knob 1008, and the top of the threaded knob 1008 is in contact and extruded with the rotating base 1010.

[0045] The inner wall of the rotation limiter 1002 is provided with an annular groove, which is slidably connected to the outer arc surface of the rotating disk 1003. The top of the sliding column 1007 is provided with a magnet. The inner wall of the guide groove 1011 provided on the rotating base 1010 is provided with a metal piece. The sliding column 1007 is magnetically connected to the bottom of the inner wall of the guide groove 1011.

[0046] The specific working principle is: this device can use a magnetic connection method to prevent the protective part 1006 from being dislocated and losing its protective effect due to the falling off of the sliding column 1007 during use. At the same time, this device uses a combination of magnetic connection structures to avoid the sliding column 1007 and the protective part 1006 from breaking when a sudden impact occurs by disengaging the sliding column 1007 from the inner wall of the guide groove 1011, thereby facilitating subsequent reinstallation and use, reducing the risk of damage to the device.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
