[0020] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0021] like Figure 1-Figure 4 As shown, a cableway safety transport platform for dangerous rock management primarily consists of a feeding platform A, a discharge platform B, a main cable C, a pulley carrier D, a drive device E, a moving rope F, and a lifting frame G. The main cable C and feeding platform A are positioned between the discharge platform B. The pulley carrier D is mounted on the main cable C. The feeding platform A is also equipped with a drive device E, which is connected to the pulley carrier D via a moving rope F. The drive device E can move the pulley carrier D along the main cable C between the feeding platform A and the discharge platform B. A lifting frame G is mounted on the feeding platform A to raise the main cable C. During use, both the feeding platform A and the discharge platform B are positioned on dangerous rock, with a container containing materials or tools used for dangerous rock management hoisted below the pulley carrier D. It is important to note that the distance between the feeding platform and the discharge platform is kept at approximately 100 meters to avoid excessive spans that could affect access.

[0022] Both feeding platform A and unloading platform B are constructed from a safety scaffolding. The scaffolding structure is conventional, consisting of several vertically arranged platform posts in a rectangular configuration. The lower end of each post is mounted on platform anchor bars, which are anchored in the ground. Since the anchor bars require cement pouring, to ensure they do not become a tripping hazard after disassembly of feeding platform A and unloading platform B, the anchor bars are elevated at a height of no less than 0.5 m above the ground. To facilitate standing, crisscrossing horizontal bars are placed at the upper ends of the posts, and bamboo planks are laid on top of the bars. To prevent movement, the planks are tied to the bars. To further ensure the safety and support of the platforms, guardrails are installed around the bars. A crisscrossing bottom horizontal bar is placed at the middle and lower ends of the posts, with platform scissor braces or diagonal braces placed between the bottom horizontal bars and the horizontal bars. In this embodiment, the guardrails are no less than 1.2 m high.

[0023] To ensure the stability of the platform anchor bars, it is necessary to ensure that the soil layer depth of the platform anchor bars is not less than 1.5m, and the rock layer depth is not less than 0.5m. In order to build the platform conveniently and quickly, the platform anchor bars are made of threaded steel, and the platform vertical poles, platform bottom horizontal poles and platform horizontal poles are all made of steel pipes. The platform anchor bars and platform vertical poles are connected by threads, and the platform vertical poles and platform horizontal poles, as well as the platform vertical poles and platform bottom horizontal poles are all connected by rotating fasteners.

[0024] The lifting frame G is set in the middle of the feeding platform. The lifting frame adopts a scaffolding-built derrick. The specific structure includes lifting uprights arranged in a rectangular shape. The lower end of each lifting upright is mounted on the lifting anchor bar, and the lifting anchor bar is anchored in the ground. Since the platform anchor bar needs to be poured with cement, in order to ensure that the platform anchor bar will not cause stumbling after the feeding platform A and the unloading platform B are dismantled, the height of the lifting anchor bar exposed to the ground is not less than 0.5m. Since the lifting frame is used to lift the main cable, the height of the lifting frame is relatively high, so the lifting frame requires higher strength. The lifting uprights are sequentially arranged from bottom to top with crisscross sweeping rods, at least one layer of lifting cross bars spaced up and down, and ceiling rods. The front and rear sides of the lifting frame are both provided with platform scissor braces, and the left and right sides of the lifting frame G are provided with platform diagonal braces. At the same time, lifting tension ropes are provided at the four inflection points of the lifting frame G, and the other ends of the lifting tension ropes are provided on the lifting ground anchors. Preferably, the lifting anchor adopts a concrete anchor pier made of multiple layers of protective net anchors. The protective net anchor is a mesh structure formed by crisscrossing steel wire ropes, and the length and width of the concrete anchor pier are not less than 3m.

[0025] To ensure the stability of the lifting anchor bars, it is necessary to ensure that the soil layer depth of the lifting anchor bars is not less than 1.5m, and the rock layer depth is not less than 0.5m. The lifting anchor bars and the lifting vertical poles are connected by threads, and the lifting vertical poles and the sweeping poles, the lifting vertical poles and the lifting cross poles, and the lifting vertical poles and the ceiling poles are all connected by rotating fasteners.

[0026] The specific structure of the rotating fastener includes a first fastener and a second fastener, wherein the first fastener includes a first buckle plate 1 and a second buckle plate 2 that are spaced apart and arranged opposite to each other, and the left and right ends of the first buckle plate 1 and the second buckle plate 2 are connected by a first connecting bolt 3, and a first lining plate 4 is arranged in the second buckle plate 2, and the first lining plate 4 extends vertically downward and is provided with a first connecting rod 5 that passes through the second buckle plate 2, and the first connecting rod 5 is provided with a ball joint 6 after passing through the second buckle plate 2, and the outer cover of the ball joint 6 is provided with a ball joint seat 7.

[0027] The second fastener includes a third buckle plate 8 and a fourth buckle plate 9 that are spaced apart and arranged opposite to each other, and the left and right ends of the third buckle plate 8 and the fourth buckle plate 9 are connected by a second connecting bolt 10. A second lining plate 11 is provided in the third buckle plate 8, and the second lining plate 11 extends vertically upward to provide a second connecting rod 12 that passes through the third buckle plate 8. After passing through the third buckle plate 8, the second connecting rod 12 is provided with a tightening nut 13 that can be tightened on the ball joint seat 7.

[0028] To achieve rotation of the ball joint, a ball joint hole 7a for accommodating the ball joint 6 is provided within the ball joint seat 7. Two ball sockets 14 are disposed in the ball joint hole 7a, which are positioned opposite each other. A compression spring 15 is disposed within the compression nut 13. A support washer 16 is disposed between the compression spring 15 and the lower end of the ball socket 14. A corner sealing gasket 17 is also disposed between the ball joint seat 7 and the third gusset plate 8 to prevent rainwater from entering. In this embodiment, a backing plate is also disposed between the first gusset plate 1 and the fourth gusset plate 9.

[0029] The rotating fastener of the above structure is used to connect the first fastener and the second fastener through a ball joint so that it can achieve 360° rotation, thereby realizing the fastening between the vertical pole and the horizontal pole, between the vertical pole and the scissors brace or diagonal brace, and between the horizontal pole and the scissors brace or diagonal brace.

[0030] To ensure the stability of the connection and the height of the main cable, the main cable C is located at one end of the feeding platform A and supported by the lifting frame G, and both ends of the main cable C are set on the cable ground anchor located on the outside B of the feeding platform A or the unloading platform. The cable ground anchor uses a concrete anchor pier made of a protective net anchor.

[0031] The specific structure of the pulley carrier D includes a fixed pulley 18, and the fixed pulley 18 is set on a "U"-shaped fixed pulley seat 20 through a fixed pulley shaft 19. A cable groove 18a is provided on the fixed pulley 18, and the width of the cable groove 18a matches the diameter of the main cable C. The depth of the cable groove 18a is not less than the radius of the main cable C. The main cable C is located between the fixed pulley seat 20 and the cable groove 18a. The lower end of the fixed pulley seat 20 is provided with a hook 21 for lifting materials.

[0032] In order to prevent the hook from rotating, thereby causing the material to shake and then cause the material to fall off, an anti-rotation structure is provided between the hook 21 and the fixed pulley seat 20 to prevent the hook 21 from rotating. The anti-rotation structure specifically includes an anti-rotation seat 22 correspondingly arranged above the hook 21, and a threaded rod 23 is vertically extended from the upper end of the anti-rotation seat 22. The lower end of the fixed pulley seat 20 is provided with a threaded hole for the threaded rod 23 to pass through. After the threaded rod 23 passes through the threaded hole, a limit plate 25 is provided. The threaded rod 23 after passing through the threaded hole is covered with a compression spring 24, and the maximum compression height of the compression spring 24 is greater than the maximum height difference between the limit plate 25 and the lower inner side of the movable pulley seat, and the minimum distance between the limit plate 25 and the cable groove 18a is greater than the diameter of the main cable C; the lower end of the anti-rotation seat 22 is provided with a mounting groove 22a for mounting the hook, and a mounting rod 26 is provided in the mounting groove. The upper end of the hook is provided with a through hole for the mounting rod 26 to pass through, and the width of the upper end of the hook 21 matches the width of the mounting groove 22a.
