DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown, the utility model relates to a mechanical anti-fall safety device for high-altitude operations, comprising a hanging basket 1, with protective mechanisms 2 provided on both sides of the hanging basket 1.

[0022] Specifically, such as Figures 1 to 3As shown, the protective mechanism 2 includes a steel cable 201 and a mounting box 202. The steel cable 201 is arranged on the side of the hanging basket 1, and a retaining ring 203 is fixedly sleeved at equal intervals on the surface of the steel cable 201. The outer wall of one side of the mounting box 202 is fixedly connected to the side of the hanging basket 1. A through hole 2021 is provided in the mounting box 202, which passes through the mounting box 202. The steel cable 201 is passed through the through hole 2021, and the side of the retaining ring 203 is connected to the inner wall of the through hole 2021. The mounting box 202 is provided with a mounting groove 2022 along the inner wall of the through hole 2021, and a U-shaped plug rod 204 is provided in the mounting groove 2022. The mounting groove 2022 is provided along one side of the hanging basket 1. A circular hole 2023 is provided to connect the mounting groove 2022 with the outside, a mounting hole 2024 is provided along the middle of the circular hole 2023 of the mounting box 202, a guide rod 205 is provided in the circular hole 2023, one end of the guide rod 205 is rotatably connected to the closed end of the U-shaped plug rod 204, and the other end of the guide rod 205 extends to the outside of the mounting box 202, and a limiting ring 206 is fixedly provided along one end of the mounting hole 2024 of the guide rod 205, and a spring 207 is provided along the limiting ring 206 of the guide rod 205, and one end of the spring 207 is fixedly connected to the inside of the other end of the mounting hole 2024, and a slider 2061 is provided at the top and bottom of the limiting ring 206. The bottom is provided with a slide groove 2025 adapted to the slider 2061, and the slide groove 2025 is provided with an annular groove 2026 connected to the slide groove 2025 and adapted to the slider 2061 near one end of the spring 207. The guide rod 205 extends to the outside of the installation box 202 and is fixedly connected to the pull rod 208 at one end. Before the hanging basket 1 rises or falls, the guide rod 205 is pulled by the pull rod 208, so that the guide rod 205 drives the slider 2061 on the limiting ring 206 along the slide groove 2025 to the annular groove 2026, driving the U-shaped plug 204 to move from the through hole 2021 to the installation groove 2022, and at the same time, the spring 2 07 is compressed in the mounting hole 2024, and the guide rod 205 is rotated by the pull rod 208 to drive the slider 2061 to be stuck in the annular groove 2026. After the hanging basket 1 rises or falls to the specified height, the guide rod 205 is rotated in the opposite direction by the pull rod 208 to drive the slider 2061 to rotate from the annular groove 2026 to the slide groove 2025. The spring 207 drives the ends on both sides of the open end of the U-shaped rod 204 into the mounting grooves 2022 on both sides of the through hole 2021, so that the two sides of the open end of the U-shaped rod 204 are stuck on the top of the retaining ring 203 on the surface of the steel cable 201, thereby preventing the hanging basket 1 from falling. Among them, the two ends of the steel cable 201 should first be fixed to the ground and the roof of the building respectively.

[0023] Further, such as Figure 4As shown, the top diameter of the retaining ring 203 is smaller than the bottom diameter of the retaining ring 203, and a guide surface A2031 is provided on the outside of the retaining ring 203. The top length of the ends on both sides of the open end of the U-shaped plug 204 is greater than the bottom length of the ends on both sides of the open end of the U-shaped plug 204, and an open guide surface B2041 is provided on both sides of the open end of the U-shaped plug 204.

[0024] In further, as Figure 4 As shown, the guide surface A2031 is an arc surface that gradually bends from the top of the outer side of the retaining ring 203 to the bottom of the outer side of the retaining ring 203 and is concave toward the center of the retaining ring 203, and the guide surface B2041 is an arc surface that gradually bends from the top of the open end of the U-shaped rod 204 to the bottom of the open end of the U-shaped rod 204 and is convex toward the outer side of the open end of the U-shaped rod 204. When the guide surface A2031 and the guide surface B2041 are opposite to each other, the two arc surfaces are connected to facilitate the U-shaped rod 204 to slide to the top of the retaining ring 203, preventing the side of the retaining ring 203 from being opposite to the open end of the U-shaped rod 204, so that the U-shaped rod 204 is supported by the side of the retaining ring 203.

[0025] Furthermore, if Figure 2 As shown, the length of the installation box 202 is greater than the distance between the opposite ends of two adjacent retaining rings 203, so as to prevent the installation box 202 from being stuck between the two adjacent retaining rings 203 and affecting the movement of the hanging basket 1.

[0026] It is worth noting that Figure 3 As shown, the distance between the opposite ends of the open end of the U-shaped rod 204 is smaller than the top diameter of the retaining ring 203, which is convenient for locking, and the two side surfaces of the U-shaped rod 204 are slidably connected to the inner walls of the mounting groove 2022 to prevent the U-shaped rod 204 from shaking.

[0027] Working principle: This embodiment provides a mechanical anti-fall safety device for aerial work. When in use, before the hanging basket 1 rises or falls, the guide rod 205 is pulled by the pull rod 208, so that the guide rod 205 drives the slider 2061 on the limit ring 206 along the circular hole 2023 to slide along the slide groove 2025 to the ring groove 2026, driving the U-shaped insertion rod 204 from the through hole 2021 to the installation groove 2022, and at the same time, the spring 207 is compressed in the installation hole 2024, and the guide rod 205 is pulled down. 8 The rotating guide rod 205 drives the slider 2061 to be stuck in the annular groove 2026. After the hanging basket 1 rises or falls to the specified height, the guide rod 205 is rotated in the opposite direction by the pull rod 208 to drive the slider 2061 to rotate from the annular groove 2026 to the slide groove 2025. The spring 207 drives the ends on both sides of the open end of the U-shaped rod 204 to enter the mounting grooves 2022 on both sides of the through hole 2021, so that the two sides of the open end of the U-shaped rod 204 are stuck on the top of the retaining ring 203 on the surface of the steel cable 201, thereby preventing the hanging basket 1 from falling.

[0028] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
