[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Refer to Figure 1 , Figure 2 and Figure 6 As shown in [relevant figures], an embodiment provided by the present invention: A numerically controlled lifting feed door applied to a construction hoist, including a feed door 1. The feed door 1 is the main structure of the entire lifting feed door 1, which is used to play a role in lifting and protecting internal equipment on the construction hoist. A plurality of ventilation holes 2 are opened inside the feed door 1. The function of the ventilation holes 2 is to promote the internal air circulation to ensure the normal operation of the internal equipment, so that the wind can penetrate the ventilation holes 2 to prevent the wind from making large-area contact with the feed door 1 and causing the feed door 1 to be blown. Both the left and right sides of the feed door 1 are fixedly connected with cages 3. The cages 3 are slidably connected with a lifting platform 25 on the left and right. Through the lifting platform 25, the cages 3 can move up and down. The rear end of the cages 3 is fixedly connected with a control module 16. Through the control module 16, the feed door 1 can be lifted and lowered. A hole 24 is opened on the right side of the feed door 1. The hole 24 is prepared for clamping subsequent workpieces. The cages 3 are usually the loading areas of the construction hoist, which are used to carry and transport workers, equipment and materials to various heights at the construction site. Both the left and right sides of the front end of the feed door 1 are fixedly connected with fixed plates 4. The adjacent ends of the two fixed plates 4 are slidably connected with a baffle 5. The function of the fixed plates 4 is to enhance the structural stability of the feed door 1 and serve as the sliding support for the baffle 5;
[0036] Refer to Figure 5, sliding components for moving the baffle 5 are fixedly connected to both the left and right sides of the baffle 5. The sliding components include two sliders 15. The sliders 15 are workpieces that can move the baffle 5. The adjacent ends of the two sliders 15 are respectively fixedly connected to the left and right sides of the baffle 5. Chutes 14 are respectively opened inside the adjacent ends of the two fixing plates 4. The outside of the slider 15 is slidably connected inside the chute 14. This design enables the baffle 5 to move smoothly on the fixing plate 4 and prevents the baffle 5 from shifting up and down while moving;
[0037] Refer to Figure 3 and Figure 4 , a support rod 6 is fixedly connected to the adjacent ends of the two fixing plates 4. The support rod 6 is designed so that subsequent workpieces can be placed outside. Fixed sleeves 8 are respectively fixedly connected to the outside of the left and right sides of the support rod 6. The fixed sleeves 8 are designed to place the moving range of subsequent workpieces. Springs 9 are respectively sleeved on the outside of the left and right sides of the support rod 6. The springs 9 can absorb the impact force of subsequent workpieces. Sliding sleeves 7 are respectively slidably connected to the outside of the left and right sides of the support rod 6. One end of the spring 9 is fixedly connected to one side of the sliding sleeve 7. The sliding sleeve 7 can squeeze the spring 9 to achieve the effect of absorbing the impact force. The other end of the spring 9 is fixedly connected to one side of the fixed sleeve 8. When the spring 9 is stressed, the force received can be transmitted to the fixed sleeve 8 to achieve the effect of unloading the force. The front end of the sliding sleeve 7 is rotatably connected to a linkage rod 10. The force received can be transmitted to the sliding sleeve 7 through the linkage rod 10. The front ends of the two linkage rods 10 are rotatably connected to a damper 11. When the damper 11 is stressed, it will move backward to drag the linkage rod 10. The front end of the damper 11 is fixedly connected to a fixed disk 12. Linkage rods 13 are respectively fixedly connected to the outer periphery of the fixed disk 12. The fixed disk 12 and the linkage rods 13 are designed to support the baffle 5. The front end of the fixed disk 12 is fixedly connected to the rear end of the baffle 5. The front ends of multiple linkage rods 13 are fixedly connected to the rear end of the baffle 5. At the same time, the fixed disk 12 and the linkage rods 13 can absorb the impact force received by the baffle 5 and transmit it backward.
[0038] Refer to Figure 6 - Figure 8, a limiting component for restricting the feeding door 1 is slidably connected to the rear end of the feeding door 1. The limiting component includes a handle 17, and the outside of the handle 17 is slidably connected to the inside of the rear end of the feeding door 1. The handle 17 can be inserted into the inside of the feeding door 1 for movement. A lever 18 is rotatably connected to the front end of the handle 17. The handle 17 can control the lever 18 to push the subsequent workpiece. A stabilizing plate 19 is fixedly connected to the inside of the hole 24. The stabilizing plate 19 can provide a fixing effect for the subsequent workpiece. Limiting blocks 20 are fixedly connected to both the left and right sides of the rear end of the stabilizing plate 19. A bolt 22 is slidably connected to the inside of the two limiting blocks 20. The limiting blocks 20 can limit the up-and-down swing of the bolt 22 and at the same time allow the bolt 22 to slide inside it. Two passive rods 21 are fixedly connected to the rear end of the bolt 22. By rotating the lever 18 rotatably connected to the handle 17, the lever 18 can rotate to push the passive rod 21, so that the bolt 22 can move to one side. A limiting groove 23 is opened on the right side of the cage 3. The outside of the right side of the bolt 22 is engaged with the limiting groove 23. When the bolt 22 moves, one end of it can be engaged inside the limiting groove 23, achieving the restriction of not being able to lift or lower the cage 3. The outside of the lever 18 is in contact with the outside of the passive rod 21. The lever 18 can toggle the passive rod 21. When the lever 18 is pulled out, the lever 18 and the handle 17 will be in a straight line and then go out through the small hole opened at the rear end of the feeding door 1.
[0039] Working principle: When the baffle 5 is impacted, the baffle 5 can transmit the received force to the fixed disk 12 and the connecting rod 13 to move backward. The chute 14 and the slider 15 are designed to prevent the baffle 5 from shifting up and down when moving. When the fixed disk 12 and the connecting rod 13 are impacted, the force will be transmitted to the damper 11 for buffering and then move backward. Secondly, when the damper 11 moves, the two linkage rods 10 can be offset to the left and right sides to drive the sliding sleeve 7 to move. When the sliding sleeve 7 moves, it can squeeze the first spring 9 to relieve pressure, so that the object hitting the baffle 5 is blocked, thus achieving the effect of protecting the feeding door 1.
[0040] By inserting the handle 17 and the lever 18, due to the rotational relationship of the lever 18, the lever 18 can be inserted into the inside of the hole 24 in a straight line form. At this time, by rotating the handle 17 to toggle one of the passive rods 21 to move, and then operating repeatedly until the bolt 22 is inserted into the inside of the limiting groove 23 for engagement. Conversely, when separation is required, reverse the handle 17. The limiting block 20 is a workpiece that can allow the bolt 22 to slide inside it.
[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
