Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a high-altitude operation fall prevention device, including a rectangular box 1. A partition 2 is fixedly installed between the inner walls of the rectangular box 1 near the middle position. A control mechanism 3 is provided inside the rectangular box 1. A drive mechanism 4 is fixedly installed on the partition 2. The drive mechanism 4 is fixedly connected to a winding roller 5. The winding roller 5 is fixedly installed between the right side wall of the rectangular box 1 and a mounting frame 7 through a first bearing assembly 6. The mounting frame 7 is fixedly installed on the right side of the rectangular box 1. A braking mechanism 8 is provided on the drive mechanism 4. The braking mechanism 8 is installed on the lower inner wall of the rectangular box 1. A first clamping mechanism 9 is fixedly installed on the left side of the rectangular box 1. A pull rope 10 is provided on the winding roller 5. A guide mechanism 11 is provided on the pull rope 10. A second clamping mechanism 12 is fixedly installed on the left side of the guide mechanism 11. A lifting ring 13 is fixedly installed on the upper end of the pull rope 10.

[0024] like Figure 2 As shown, in some embodiments, the control mechanism 3 includes a controller 301, a Bluetooth receiver module 302, and a battery 303. The controller 301 is fixedly installed on the upper inner wall of the rectangular box 1, the Bluetooth receiver module 302 is installed on the rectangular box 1 corresponding to the controller 301, and the battery 303 is installed on the lower inner wall of the rectangular box 1.

[0025] In this embodiment, the Bluetooth receiving module 302 is wirelessly connected to an external Bluetooth remote control. The external Bluetooth remote control sends instructions to the controller 301 through the Bluetooth receiving module 302. The controller 301 controls the winding of the drive mechanism 4 to achieve the effect of winding and unwinding the pull rope 10. At the same time, the controller 301 controls the opening and closing of the brake mechanism 8.

[0026] like Figure 2 As shown, in some embodiments, the drive mechanism 4 includes a motor 401 and a transmission rod 402. The motor 401 is fixedly installed on the left side of the partition 2, and the transmission rod 402 is fixedly installed on the right side of the output shaft of the motor 401. The right side of the transmission rod 402 is fixedly connected to the left side of the take-up roller 5.

[0027] In this embodiment, the output shaft of the motor 401 drives the transmission rod 402 to rotate, which in turn drives the take-up roller 5 to rotate. By adjusting the forward and reverse rotation of the motor 401, the pull rope 10 can be wound up and unwound.

[0028] like Figure 2 As shown, in some embodiments, the braking mechanism 8 includes a brake disc 801, an electric telescopic rod 802, a connecting rod 803, and brake pads 804. The brake disc 801 is fixedly installed on the transmission rod 402. The electric telescopic rod 802 is mirror-installed on the inner wall of the lower side of the rectangular box 1 corresponding to the brake disc 801. The output shaft of the electric telescopic rod 802 is connected to the connecting rod 803, and brake pads 804 are fixedly installed on the facing sides of the left and right connecting rods 803.

[0029] In this embodiment, the output shaft of the left and right electric telescopic rods 802 drives the brake pads 804 on the connecting rod 803 away from the brake disc 801, thereby enabling the transmission rod 402 on the brake disc 801 to rotate. When the left and right electric telescopic rods 802 are closed, the output shaft of the left and right electric telescopic rods 802 drives the brake pads 804 on the connecting rod 803 to move toward the brake disc 801, so that the left and right brake pads 804 clamp and fix the brake disc 801, thereby preventing the transmission rod 402 on the brake disc 801 from rotating.

[0030] like Figure 2 As shown, in some embodiments, the first clamping mechanism 9 includes a rectangular frame 901, a bolt rod 902, a second bearing assembly 903, and a clamping plate 904. The rectangular frame 901 is fixedly installed on the left side of the rectangular box 1. The bolt rod 902 is threadedly installed on the upper surface of the rectangular frame 901, and the clamping plate 904 is fixedly installed on the lower surface of the bolt rod 902 through the second bearing assembly 903.

[0031] In this embodiment, the bolt rod 902 moves spirally downward on the rectangular frame 901, causing the bolt rod 902 to drive the clamping plate 904 downward through the second bearing assembly 903, so that the clamping plate 904 is clamped to the lower side wall of the rectangular frame 901 on the fixed object.

[0032] like Figure 2 As shown, in some embodiments, the right side of the clamping plate 904 is movably fitted with the right inner wall of the rectangular frame 901, and the second clamping mechanism 12 has the same structure as the first clamping mechanism 9.

[0033] In this embodiment, the clamping plate 904 moves up and down along the inner wall of the rectangular frame 901, so that the clamping plate 904 moves up and down stably, and the second clamping mechanism 12 can install and fix the guide mechanism 11.

[0034] like Figure 3 As shown, in some embodiments, the guiding mechanism 11 includes a fixed frame 111 and V-shaped guide rollers 112. V-shaped guide rollers 112 are installed between the front and rear side walls of the fixed frame 111 near the left and right positions, and the left and right V-shaped guide rollers 112 are installed on the left and right sides of the pull rope 10.

[0035] In this embodiment, the fixing frame 111 is used to fix the left and right V-shaped guide rollers 112, and the V-shaped guide rollers 112 guide the pull rope 10.

[0036] In use, the bolt rod 902 in the first clamping mechanism 9 spirals downward on the rectangular frame 901, causing the bolt rod 902 to drive the clamping plate 904 downward through the second bearing assembly 903. This clamps the clamping plate 904 against the lower side wall of the rectangular frame 901, achieving the effect of clamping and fixing the rectangular box 1. The user moves the box by carrying the lifting ring 13 and the pull rope 10. At this time, the Bluetooth receiving module 302 in the control mechanism 3 needs to be wirelessly connected to the external Bluetooth remote control. The external Bluetooth remote control sends a command to the controller 301 through the Bluetooth receiving module 302. The controller 301 causes the output shaft of the left and right electric telescopic rods 802 in the braking mechanism 8 to drive the brake pads 804 on the connecting rod 803 away from the brake disc 801, thereby enabling the transmission rod 402 on the brake disc 801 to rotate. The controller 301 then causes the output shaft of the motor 401 in the drive mechanism 4 to drive the transmission rod 402 to rotate. The transmission rod 402 rotates, causing the take-up roller 5 to rotate. The take-up roller 5 then drives the pull rope 10 to unload the line. After reaching a certain height, the second clamping mechanism 12 fixes the fixed frame 111 in the guide mechanism 11. The left and right V-shaped guide rollers 112 in the fixed frame 111 guide and limit the pull rope 10. Multiple sets of guide mechanisms 11 can be used. When the pull rope 10 does not need to be loosened, the output shaft of the left and right electric telescopic rods 802 drives the brake pads 804 on the connecting rod 803 to move towards the brake disc 801, so that the left and right brake pads 804 clamp and fix the brake disc 801, thereby preventing the transmission rod 402 on the brake disc 801 from rotating, achieving the effect of limiting the pull rope 10. The operator can adjust the length of the pull rope 10 himself, making the range of motion of the fall protection device wider. Therefore, there is no need to remove the fall protection device, greatly increasing safety and making operation more convenient, which can meet the needs of various high-altitude operations.

[0037] In summary, this high-altitude operation fall protection device, by allowing for self-adjustment of the length of the pull rope 10, has a wider range of motion and does not require disengagement during operation, greatly increasing safety and making operation more convenient.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
