[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Refer to Figures 1 - 5The utility model provides an embodiment: a safety anti-falling device for ordinary high-rise residential construction, comprising a hollow column 1 and an adjusting box 2, the outer wall of the hollow column 1 is fixedly connected with a bracket 3, the front outer wall of the bracket 3 is rotatably connected with a main shaft 4, the outer wall of the main shaft 4 is fixedly connected with a spiral turntable 5, the rear outer wall of the spiral turntable 5 is meshedly connected with a tooth column 6, the outer wall of the tooth column 6 is slidably connected to the inner wall of the hollow column 1, the upper surface of the tooth column 6 is fixedly connected with a guardrail 7, the outer wall of the guardrail 7 is slidably connected with a fixed column 8, the front outer wall of the main shaft 4 is rotatably connected with a crank 9, the upper outer wall of the crank 9 is rotatably connected with a rocker 10, the outer wall of the rocker 10 is fixedly connected with a shifting block 11, the middle outer wall of the main shaft 4 is fixedly connected with a gear 12, the lower surface of the shifting block 11 is arranged on the upper outer wall of the gear 12, and the outer wall of the adjusting box 2 is fixedly connected with a restraining component.
[0027] Specifically, Figure 2 The front-to-back sequence is that the crank handle 9 is in front and the gear 12 is in the back. The gear 12 and the spiral turntable 5 rotate together through the main shaft 4. The gear 12 is on the front side of the spiral turntable 5, and the back side of the main shaft 4 rotates on the front side of the bracket 3. The bracket 3 supports the main shaft 4 to rotate. When it is necessary to lift or lower, press the crank handle 9 downward to drive the rocker 10 to rotate. The rotation of the rocker 10 will pull the shift block 11, and the shift block 11 shifts the gear 12 to rotate. The gear 12 drives the main shaft 4 to rotate, and the main shaft 4 drives the spiral turntable 5 to rotate. The spiral turntable 5 drives the gear column 6 to lift through the threaded protrusion on the rear side, and then lift the crank handle 9 upward, and push the shift block 11 back to its original position, and press the crank handle 9 down again to lift it. The device has a braking function to prevent the gear column 6 from falling. When it needs to descend, push the shift block 11 and the rocker 10 to another direction, and the gear column 6 is lowered by repeatedly lifting the crank handle 9 upward.
[0028] Reference Figure 1 and Figure 2 The outer wall of the adjustment box 2 is fixedly connected with a waist belt 13 , the lower surface of the waist belt 13 is fixedly connected with a leg belt 14 , and the upper surface of the leg belt 14 is fixedly connected to the lower surface of the adjustment box 2 .
[0029] Specifically, the waist belt 13 is put on the waist of the construction worker, and then the leg belt 14 is put on the thigh of the construction worker and tightened. The fixed connection between the leg belt 14 and the waist belt 13 can make both of them evenly stressed. The leg belt 14 and the waist belt 13 are fixed to the outer wall of the adjustment box 2, and the adjustment box 2 is located in front of the construction worker for easy use.
[0030] Reference Figure 2 , Figure 6 and Figure 7, a transmission shaft 15 is rotatably connected inside the adjustment box 2. One end of the transmission shaft 15 is fixedly connected to a knob 16, and the other end of the transmission shaft 15 is fixedly connected to a ratchet wheel 17. The outer wall of the ratchet wheel 17 is meshed with a pawl 19. The outer wall of the pawl 19 is rotatably connected to a rotating shaft 25. The outer wall of the rotating shaft 25 is fixedly connected to a fixing plate 20. The upper surface of the fixing plate 20 is fixedly connected to the inner top wall of the adjustment box 2. The lower outer wall of the pawl 19 is fixedly connected to a connecting rod 21. The outer wall of the connecting rod 21 is fixedly connected to a pull rod 22. The outer wall of the pull rod 22 is slidably connected inside the adjustment box 2. The upper surface of the pull rod 22 is fixedly connected to a pull ring 23. The lower surface of the pull ring 23 is fixedly connected to a tension spring 24. The lower surface of the tension spring 24 is fixedly connected to the upper surface of the adjustment box 2. A safety rope 18 is slidably connected inside the adjustment box 2. One end of the safety rope 18 is fixedly connected to the outer wall of the transmission shaft 15, and the other end of the safety rope 18 is fixedly connected to the outer wall of the fixed column 8.
[0031] Specifically, after the construction workers put on the waist belt 13 and the leg strap 14, they rotate the knobs 16 on both sides of the adjustment box 2 to make the transmission shaft 15 rotate. The rotation of the transmission shaft 15 causes the safety rope 18 to be retracted and wound around the outer wall of the transmission shaft 15. At the same time, the transmission shaft 15 drives the ratchet wheel 17 to rotate. The ratchet wheel 17 can only rotate in one direction restricted by the pawl 19, ensuring that the length of the safety rope 18 is fixed, so that the safety rope 18 pulls the body of the construction worker to prevent falling. When the construction worker needs to extend the length of the safety rope 18, they pull up the pull ring 23 to drive the connecting rod 21 to move upward. The connecting rod 21 is fixed at a position close to the tip of the pawl 19. The connecting rod 21 drives the tip of the pawl 19 to lift upward. The pawl 19 rotates around the rotating shaft 25. The rotating shaft 25 is fixed by the fixing plate 20, and the fixing plate 20 is fixed to the inner top wall of the adjustment box 2. At this time, the transmission shaft 15 can rotate in the reverse direction to release the restriction on the safety rope 18. As long as the construction worker releases the pull ring 23 to make the tension spring 24 rebound, the pull rod 22 drives the connecting rod 21 to descend, making the pawl 19 re-engage with the ratchet wheel 17, and the safety rope 18 will be locked again.
[0032] Working principle: When using this device, first press down the crank 9 to drive the rocker 10 to rotate. The rocker 10 drives the gear 12 to rotate through the block 11. The gear 12 drives the spiral turntable 5 to rotate through the main shaft 4. The rotation of the spiral turntable 5 drives the tooth column 6 to rise, and the guardrail 7 can be raised. When it is necessary to lower the guardrail 7, turn the block 11 in the reverse direction, and then lift the crank 9 to lower the height of the guardrail 7. When the worker starts working, put on the waist belt 13 and the leg belt 14 and tighten them around the body. Then fix the safety rope 18 on the fixed column 8. Rotate the knob 16 to drive the transmission shaft 15 to rotate. While the transmission shaft 15 drives the ratchet 17 to rotate, the safety rope 18 is wound around the outer wall of the transmission shaft 15. The pawl 19 prevents the safety rope 18 from loosening, so as to hold the body of the construction worker. When the construction worker needs to move, pull the pull ring 23 to drive the connecting rod 21 to move upward through the pull rod 22. The connecting rod 21 drives the pawl 19 to disengage from the ratchet 17. At this time, the transmission shaft 15 can rotate in the reverse direction and the safety rope 18 can be lengthened. This device can not only lift and lower the guardrail 7 to facilitate construction while ensuring the protection effect, but also further protect personnel with the safety rope 18.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
