[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] A safety protection device for elevator inspection includes two first protective plates 1 and two second protective plates 2. Each of the surfaces of the two second protective plates 2 is provided with a limit mechanism 4, and the number of limit mechanisms 4 is four. A connecting mechanism 5 is provided between the tops of the two first protective plates 1.
[0030] The limiting mechanism 4 includes a suction cup 401, a pull ring 402, a rotating block 403, a rotating shaft 404, and a rotating frame 405. The pull ring 402 is fixedly connected to the suction cup 401 on the side near the suction cup 401. The rotating block 403 is fixedly connected to the suction cup 401 on the side near the suction cup 401. The rotating shaft 404 is rotatably connected to the inside of the rotating block 403. The rotating shaft 404 is rotatably connected to the inside of the rotating frame 405. The rotating frame 405 is fixedly connected to the second protective plate 2 on the side near the second protective plate 2.
[0031] In this embodiment: the operator holds the top handle 6 of the first protective plate 1, and using the rotation characteristics of the connecting block 8 and the rotating column 9, unfolds the first protective plate 1 and the second protective plate 2 to a suitable angle and moves them to the elevator car entrance. The bottom support leg 3 of the second protective plate 2 is unfolded. The connecting shaft 10 and the rotation of the support leg 3 have damping to maintain stable support. The nitrile rubber suction cup 401 is pressed against the elevator car frame. The rotating block 403, rotating shaft 404 and rotating frame 405 allow the suction cup 401 to flexibly adjust its angle and use negative pressure adsorption to fix it. After the inspection personnel enter the car between the two first protective plates 1, they insert the insertion column 502 into the insertion hole 504. The positioning plate 503 contacts the first protective plate 1, making the two first protective plates 1 in a straight line and separating the car. After the inspection is completed inside and outside the elevator car, pull out the insert 502, pull the pull ring 402 to disengage the suction cup 401, hold the handle 6 and rotate to open the first protective plate 1. The bottom ball bearing 12 reduces friction. Finally, fold the first protective plate 1 and the second protective plate 2 in a Z-shape, rotate the support leg 3, and the magnetic strip 7 to make the equipment compact and easy to store and transport. This solves the problem in the existing patent that when the protective device body is placed at the elevator entrance, it is inconvenient to fix the position of the protective device body. When one elevator car is not in use for inspection, the flow of people in the other elevator car will increase. When people walk around a lot, they are likely to accidentally bump into the protective device body, which will cause the protective device body to tilt or shift, affecting the safety protection.
[0032] Specifically, such as Figure 4 As shown, a connecting block 8 is provided between the top of the first protective plate 1 and the second protective plate 2. A rotating post 9 is provided on both sides of the top of the connecting block 8. The bottom of the two rotating posts 9 passes through the connecting block 8 and is fixedly connected to the top of the first protective plate 1 and the second protective plate 2 respectively. The surface of the rotating post 9 is movably connected to the interior of the connecting block 8.
[0033] Specifically, such as Figure 1 and Figure 5As shown, the bottom of the second protective plate 2 is provided with two support legs 3. The bottom of the support leg 3 is provided with a connecting shaft 10. The top of the connecting shaft 10 passes through the support leg 3 and is fixedly connected to the bottom of the second protective plate 2. The surface of the connecting shaft 10 is movably connected to the inside of the support leg 3. There is damping at the rotational connection between the connecting shaft 10 and the support leg 3.
[0034] Specifically, such as Figure 3 As shown, magnetic strips 7 are embedded inside both the first protective plate 1 and the second protective plate 2.
[0035] In this embodiment: the first protective plate 1 and the second protective plate 2 are rotatably connected by a connecting plate 501 and a rotating column 9, so that the first protective plate 1 and the second protective plate 2 can be folded. The support leg 3 is rotatably connected to the second protective plate 2 by a connecting shaft 10, so that the support leg 3 can be folded and unfolded, and can be limited to any position by damping. After the first protective plate 1 and the second protective plate 2 are folded, they are limited by magnetic attraction between them by magnetic strips 7.
[0036] Specifically, such as Figure 3 As shown, the connecting mechanism 5 includes a connecting plate 501, two inserts 502, two positioning plates 503, and two insertion holes 504. The top of the inserts 502 is fixedly connected to the bottom of the connecting plate 501. The side of the positioning plate 503 near the connecting plate 501 is fixedly connected to the connecting plate 501. The inserts 502 are movably inserted into the inside of the insertion holes 504. The surface of the positioning plate 503 is in contact with the surface of the first protective plate 1.
[0037] Specifically, such as Figure 3 As shown, a handle 6 is fixedly connected to the top of the first protective plate 1.
[0038] In this embodiment: by inserting the insertion post 502 into the insertion hole 504, the positioning plate 503 contacts the first protective plate 1, and the two first protective plates 1 can be kept in a straight line. The first protective plate 1 can be easily pulled by holding the handle 6.
[0039] Specifically, such as Figure 1 and Figure 6 As shown, a support column 11 is fixedly connected to the bottom of the first protective plate 1, and a ball bearing 12 is rotatably connected inside the support column 11.
[0040] Specifically, such as Figure 1 As shown, the first protective plate 1 and the second protective plate 2 are both made of polycarbonate, and the suction cup 401 is made of nitrile rubber.
[0041] In this embodiment: the first protective plate 1 is rotated and supported by the ball bearing 12, which makes the rotation and opening of the first protective plate 1 smoother. Since the first protective plate 1 and the second protective plate 2 are both made of polycarbonate, the first protective plate 1 and the second protective plate 2 have good strength and light weight. The suction cup 401 is made of nitrile rubber, which has good flexibility and adsorption performance and can adapt to the uneven surface that may exist on the elevator car frame.
[0042] Working principle: The first protective plate 1 and the second protective plate 2 are rotatably connected by the connecting block 8 and the rotating column 9, allowing them to be flexibly unfolded. The operator can hold the handle 6 at the top of the first protective plate 1 and use the rotational characteristics of the connecting block 8 and the rotating column 9 to unfold the first protective plate 1 and the second protective plate 2 to a suitable angle for deployment at the elevator inspection site. The first protective plate 1 and the second protective plate 2 are moved to the entrance of the electric car and unfolded. The second protective plate 2 is provided with a support leg 3 at the bottom. The support leg 3 is rotatably connected to the second protective plate 2 by the connecting shaft 10, and there is damping at the rotational connection between the connecting shaft 10 and the support leg 3. The support leg 3 is unfolded so that it remains stable after unfolding. The support angle is adjusted, and then the suction cup 401 is pressed onto the elevator car frame. The negative pressure between the suction cup 401 and the elevator car frame achieves adhesion and fixation. The rotating block 403, rotating shaft 404, and rotating frame 405 allow the suction cup 401 to be flexibly adjusted to better fit the elevator car frame and ensure adhesion. The suction cup 401 is made of nitrile rubber, which has good flexibility and adhesion performance, and can adapt to uneven surfaces that may exist on the elevator car frame. At this point, the first protective plate 1 and the second protective plate 2 can be fixed in position. Then, the inspection personnel enter the elevator car from between the two first protective plates 1, and then the insertion post 502 is movably inserted into the insertion hole 504. The surface of the positioning plate 503 is flush with the first protective plate 1. Surface contact ensures the connection of the two first protective plates 1, and the positioning plate 503 contacts the first protective plate 1, keeping the two first protective plates 1 in a straight line. This isolates the inside of the elevator car from the outside, preventing unauthorized personnel from entering the elevator car being inspected, thus avoiding inspection interruptions or unnecessary safety accidents. This also solves the problem in existing patents where the protective device body is inconvenient to fix at the elevator entrance. Furthermore, when one elevator car is not in use for inspection, the increased passenger flow in the adjacent elevator car can easily cause accidental collisions with the protective device body, leading to tilting or displacement. To address safety concerns, when the inspector exits the elevator car, pulling the connecting plate 501 upwards disengages the insert 502 from the socket 504. The first protective plate 1 can then be rotated open by holding the handle 6. A ball bearing 12 is rotatably connected inside the support column 11 at the bottom of the first protective plate 1. As the first protective plate 1 rotates, the ball bearing 12 reduces friction with the ground, facilitating its opening. After the elevator inspection is complete, the insert 502 on the connecting plate 501 is pulled out of the socket 504, and then the pull ring 402 is pulled to break the negative pressure between the suction cup 401 and the elevator car frame, causing the suction cup 401 to detach from its adsorption state. Since the first protective plate 1 and the second protective plate 2 are rotatably connected by the connecting block 8 and the rotating column 9...The operator can fold the first protective plate 1 and the second protective plate 2 in a Z-shape, and then rotate the support leg 3 to be parallel to the first protective plate 1. After folding, the magnetic strips 7 embedded inside the first and second protective plates 1 and 2 magnetically attract each other during the folding process, keeping the folded equipment compact and easy to store and transport.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
