[0002] An elevator is a mechanical and electrical device that is powered and runs along rigid guide rails or fixed steps to transport people or goods vertically or horizontally.
[0003] During elevator installation, the car needs to be sent into the elevator shaft through a protective device. Existing technology uses a moving plate to transport the car horizontally. However, due to the height difference between the bottom of the elevator shaft and the installation ground, the center of gravity of the moving plate will dynamically shift with the car's displacement when the car enters the elevator shaft, resulting in a decrease in the overall stability of the device and a risk of tipping over.
[0004] This paper proposes a protective safety device for elevator installation. Utility Model Content

[0020] 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.
[0021] Example 1: The top of the base 1 has a mounting groove 101. A first lead screw 102 is mounted inside the mounting groove 101 via a bearing. A slider 13 is fixed to one side of the bottom of the translation plate 8. The slider 13 is sleeved on the outside of the first lead screw 102. A limiting slide block 14 is welded to both sides of the bottom of the translation plate 8. A limiting slide groove 103 is opened on both sides of the top of the base 1. The limiting slide block 14 is slidably installed inside the limiting slide groove 103. A protective component 2 is welded to both sides of the top of the translation plate 8. A support frame 6 is welded to one side of the top of the translation plate 8. A second motor 3 is fixed to the top of the support frame 6 via bolts. A second lead screw 4 is mounted to the bottom of the support frame 6 via a bearing. A sliding plate 5 is sleeved on the outside of the second lead screw 4 via thread engagement. A support rod 9 is welded to both sides of the bottom of the sliding plate 5. A support roller 10 is fixed to the bottom of the support rod 9. A second limiting tooth 15 is welded to both sides of the sliding plate 5. A limiting component 7 is installed on both sides of the support frame 6. A first motor 104 is fixed to one side of the base 1 via bolts.
[0022] A pull rod 12 is fixed on one side of the base 1, and the output end of the first motor 104 extends into the mounting groove 101 and is fixedly connected to one end of the first lead screw 102.
[0023] Four pulleys 11 are fixed to the bottom of the base 1 by bolts, and the four pulleys 11 are located at the four corners of the bottom of the base 1.
[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when installing the elevator car, the car is placed above the sliding plate 8. Then, the entire device is moved to one side of the elevator shaft using the pull rod 12 and pulley 11. The rotation of the output end of the first motor 104 drives the first lead screw 102 to rotate. Since the outer side of the first lead screw 102 is fitted with a slider 13 via a threaded engagement, and the slider 13 is fixed to the bottom of the sliding plate 8, the rotation of the first lead screw 102 controls the sliding plate 8 to slide along the installation direction of the first lead screw 102. Because the limiting slide seats 14 of the welding machine on both sides of the bottom of the sliding plate 8 are slidably installed inside the limiting slide grooves 103, the stability of the sliding plate 8 during sliding is ensured. When one end of the sliding plate 8 moves into the elevator shaft, the operation of the first motor 104 is stopped. The rotation of the output end of the second motor 3 drives the second lead screw 4 to rotate. The sliding plate 5 slides downwards along the installation direction of the second lead screw 4, thereby causing the support roller 10 installed at the bottom of the support rod 9 to contact the bottom surface of the elevator shaft. When the sliding plate 5 slides downwards, the second limiting teeth 15 installed on both sides of the sliding plate 5 will cooperate with the limiting component 7 to limit the sliding plate 5, improve the load-bearing capacity of the sliding plate 5, improve the overall load-bearing capacity of the translation plate 8, and prevent the center of gravity of the device from shifting. At this time, the first motor 104 is turned on again to continue to control the translation plate 8 to move into the interior of the elevator shaft. During the movement of the translation plate 8, the support roller 10 will roll on the bottom surface of the elevator shaft, thereby providing stable support for the translation plate 8. Through this device, the car can be stably transported into the interior of the elevator shaft for installation, regardless of the height difference between the bottom of the elevator shaft and the installation ground, which improves the overall stability of the device and prevents the device from tipping over.
[0025] Example 2: The protective component 2 includes a protective frame 205, and a sliding groove 206 is provided inside the protective frame 205. A side plate 203 is slidably installed inside the sliding groove 206. A limit hole 202 is provided inside the side plate 203. A limit bolt 201 is connected inside the protective frame 205 by thread engagement. The limiting component 7 includes a cylinder 701, and the cylinder 701 is fixed to one side of the support frame 6 by bolts. A control plate 702 is fixed to the output end of the cylinder 701. A support slide rod 703 is welded to one side of the control plate 702. One end of each of the two support slide rods 703 slides into the support frame 6. A movable plate 707 is fixed to one end of each of the two support slide rods 703. A spring slide rod 704 is slidably installed inside the movable plate 707. A fixed plate 706 is welded to one end of the spring slide rod 704. A plurality of first limit teeth 705 are fixed at equal intervals on one side of the fixed plate 706.
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the side plate 203 can be pulled out from between the two protective frames 205 by sliding the side plate 203, thus leaving sufficient space to move the elevator car above the sliding plate 8. Then, the side plate 203 is inserted between the two protective frames 205. By rotating the limiting bolt 201, one end of the limiting bolt 201 is inserted into the limiting hole 202. When the slide plate 5 slides down, the second limiting teeth 15 fixed on both sides of the slide plate 5 will squeeze one side of the fixed plate 706, so that the second limiting teeth 15 are constantly between the two first limiting teeth 705. The cooperation between the second limiting teeth 15 and the first limiting teeth 705 can improve the support force of the slide plate 5 and prevent the slide plate 5 from having a loose thread between the second lead screw 4. By controlling the extension of the output end of the cylinder 701, the movable plate 707 can be moved outward, so that the second limiting teeth 15 are disengaged from between the two first limiting teeth 705. At this time, the slide plate 5 can be raised.
[0027] Working principle: In use, the side plate 203 can be pulled out from between the two protective frames 205 by sliding the side plate 203, thus leaving sufficient space to move the elevator car above the sliding plate 8. Then, the side plate 203 is inserted between the two protective frames 205. By rotating the limiting bolt 201, one end of the limiting bolt 201 is inserted into the limiting hole 202. Then, the entire device is moved to one side of the elevator shaft by the pull rod 12 and the pulley 11. Then, by controlling the rotation of the output end of the first motor 104, the first lead screw 102 is driven to rotate. Since the outer side of the first lead screw 102 is fitted with a slider 13 through thread engagement, and the slider 13 is fixed to the bottom of the sliding plate 8, the rotation of the first lead screw 102 can control the sliding plate 8 to slide along the installation direction of the first lead screw 102. Since the limiting slide seats 14 of the welding machine on both sides of the bottom of the sliding plate 8 are respectively slidably installed inside the limiting slide groove 103, the sliding plate 8 is guaranteed to move in the direction of the welding machine. To ensure stability during the sliding process, once one end of the sliding plate 8 moves into the elevator shaft, the first motor 104 stops operating. The second motor 3 is controlled to rotate, causing the second lead screw 4 to rotate. The rotation of the second lead screw 4 causes the sliding plate 5 to slide downwards along the installation direction of the second lead screw 4, thereby causing the support roller 10 installed at the bottom of the support rod 9 to contact the bottom surface of the elevator shaft. When the sliding plate 5 slides downwards, the second limiting teeth 15 installed on both sides of the sliding plate 5 will cooperate with the limiting component 7 to limit the sliding plate 5, improve the load-bearing capacity of the sliding plate 5, improve the overall load-bearing capacity of the sliding plate 8, and prevent the center of gravity of the device from shifting. At this time, the first motor 104 is turned on again to continue controlling the sliding plate 8 to move into the interior of the elevator shaft. During the movement of the sliding plate 8, the support roller 10 will roll on the bottom surface of the elevator shaft, thereby providing stable support for the sliding plate 8 and stably transporting the car into the interior of the elevator shaft for installation.
