[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example: Figures 1-4 As shown, this embodiment provides a coal mine chute lifting device, including a first lifting tool 1 and a second lifting tool 2. The first lifting tool 1 is used to lift one end of the coal mine chute 6; the second lifting tool 2 is used to lift the opposite end of the coal mine chute 6. The first lifting tool 1 and the second lifting tool 2 are connected by an anti-detachment component 3. This configuration connects the opposite ends of the coal mine chute 6 via the first lifting tool 1 and the second lifting tool 2, enabling lifting and transport. The structure is simple, transport is convenient, and efficiency is high. The anti-detachment component 3 prevents the lifting tools from detaching from the coal mine chute 6 during lifting and transport, improving the stability and efficiency of the transport.

[0028] In a coal mine chute lifting device according to this embodiment, the first lifting device 1 includes a first positioning plate 11 and a first U-shaped hook 12. The bottom end of the first positioning plate 11 is in contact with the upper part of the coal mine chute 6, and the upper part of the first positioning plate 11 is used to connect the first lifting hook 4. One end of the first U-shaped hook 12 is fixedly connected to the first positioning plate 11, and the first U-shaped hook 12 is used to engage and position one side end of the coal mine chute 6. With this arrangement, the bottom of the first positioning plate 11 is in contact with the upper part of the coal mine chute 6, and in conjunction with the first U-shaped hook 12, the connection stability between the first lifting device 1 and the coal mine chute 6 is improved.

[0029] In a coal mine chute lifting device according to this embodiment, the second lifting device 2 includes a second positioning plate 21 and a second U-shaped hook 22. The bottom end of the second positioning plate 21 is attached to the upper part of the coal mine chute 6, and the upper part of the second positioning plate 21 is used to connect the second lifting hook 5. One end of the second U-shaped hook 22 is fixedly connected to the second positioning plate 21, and the second U-shaped hook 22 is used to engage and position one side of the coal mine chute 6. With this arrangement, the bottom of the second positioning plate 21 is attached and abuts against the upper part of the coal mine chute 6, and in conjunction with the second U-shaped hook 22, the connection stability between the second lifting device 2 and the coal mine chute 6 is improved.

[0030] In this embodiment of a coal mine chute lifting device, the first positioning plate 11 and the second positioning plate 21 have the same shape, and the first positioning plate 11 and the second positioning plate 21 are symmetrically located at opposite ends of the coal mine chute 6. This arrangement results in more balanced force distribution, making the lifting and transportation process more stable and efficient.

[0031] In a coal mine chute lifting device according to this embodiment, a first through hole 13 is provided on the first positioning plate 11 for the first lifting hook 4 to pass through. The first through hole 13 is located near one side of the first positioning plate 11. A second through hole 23 is provided on the second positioning plate 21 for the second lifting hook 5 to pass through. The second through hole 23 is located near one side of the second positioning plate 21. The first through hole 13 and the second through hole 23 are aligned. This arrangement is simple in structure and facilitates the connection and disassembly of the first lifting hook 4 and the first positioning plate 11, as well as the connection and disassembly of the second lifting hook 5 and the second positioning plate 21. Since the first through hole 13 and the second through hole 23 are both located on the same side, the coal mine chute 6 can be transported in an inclined state during the lifting process, saving space. Due to the protruding structure on both sides of the coal mine chute 6, the first U-shaped hook 12 and the second U-shaped hook 22 are limited, ensuring that the first U-shaped hook 12 and the second U-shaped hook 22 will not detach from the coal mine chute 6 during the inclined transport process.

[0032] In a coal mine chute lifting device according to this embodiment, the height of the side with the first through hole 13 on the first positioning plate 11 is higher than the height of the opposite side, and the height of the side with the second through hole 23 on the second positioning plate 21 is higher than the height of the opposite side. This arrangement helps to reduce the weight of the lifting device and lower transportation costs.

[0033] In this embodiment of a coal mine chute lifting device, there are several first U-shaped hooks 12, evenly distributed along the length of the first positioning plate 11; and several second U-shaped hooks 22, evenly distributed along the length of the second positioning plate 21. This arrangement improves the connection stability between the lifting device and the coal mine chute 6, thereby making the lifting and conveying of the coal mine chute 6 more efficient and stable.

[0034] In this embodiment of a coal mine chute lifting device, the anti-detachment component 3 is an anti-detachment metal chain. The structure is simple, preventing the lifting device from separating from the coal mine chute 6 during lifting, and also facilitating the assembly and disassembly of the lifting device from the coal mine chute 6.

[0035] In this embodiment of a coal mine chute lifting device, the upper part of the first positioning plate 11 and the upper part of the second positioning plate 21 are both curved. This avoids damage to other parts during lifting, making it safer to use.

[0036] Benefit calculation:

[0037] Direct labor cost = 45 workers * 350 yuan / worker * 2 days = 31,500 yuan.

[0038] Indirect costs = 0.5 million yuan / day * 2 days = 10,000 yuan.

[0039] The use of this device saves 41,500 yuan in costs during the dismantling, installation and hoisting of scraper conveyors in each coal mining face, and has good social safety benefits, mainly by increasing the operational safety factor by 25%.
