Description

Technical Field

[0001] This application relates to the technical field of elevators, and in particular to a bottom cage for a high-rise elevator. Background Technology

[0002] The hoist base cage, also known as the outer cage, is an important component of the construction hoist. It serves as the supporting foundation for the guide rail frame, bearing the entire weight of the guide rail frame, the cage, and the personnel and materials carried. It is firmly connected to the foundation through anchor bolts or embedded parts to ensure the overall structural stability of the hoist.

[0003] A search revealed Chinese Patent Publication No. CN221027068U, which discloses an adjustable cage bottom structure for a hoist. The structure includes a cage bottom plate, connecting plates on opposite sides of the bottom plate, and an adjustment device on adjacent sides of the connecting plates. A main body device is fixedly connected to the upper ends of the two connecting plates. The two connecting plates can extend movably into the interior of the cage bottom plate. Mounting grooves are provided on opposite sides of the two connecting plates. The two connecting plates can move in adjacent directions or in opposite directions, thereby driving the main body device above. This device increases the space of the cage bottom plate by adjusting the position of the two connecting plates, reducing the impact on the workers' working space due to insufficient space. Furthermore, the lateral area of ​​the entire device can be changed by adjusting the two connecting plates, allowing it to adapt to a wider range of hoistways with varying widths.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: the existing technology lacks a sealing mechanism, making it difficult to protect the interior of the bottom cage. This allows debris or personnel to easily enter the bottom cage, affecting the normal operation of the elevator and potentially causing safety accidents. To address the deficiency of the existing technology in lacking a sealing mechanism, this application achieves the sealing of the interior of the bottom cage by using a rack and pinion mechanism and a drive bar to open and close the protective door via a support rod. This effectively prevents debris or personnel from entering the bottom cage. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-6 The figure provides a further detailed description of this application.

[0024] This application discloses a base cage for a high-rise elevator. For example... Figure 1 , 2As shown in Figures 3 and 4, a high-rise elevator base cage includes a base 1. An outer cage 2 is fixedly connected to the upper surface of the base 1. A steel cable lifting device is installed inside the outer cage 2. A slide rail is fixedly installed inside the outer cage 2. A base plate 16 is provided inside the outer cage 2. Two protective doors 3 are hinged to the front of the outer cage 2. The protective doors 3 are symmetrically installed. Each protective door 3 is rotatably connected to two support rods 4. Two drive bars 5 are slidably connected inside the outer cage 2. The drive bars 5 are symmetrically installed. Both ends of each drive bar 5 are rotatably connected to the corresponding support rod 4. A first rack 6 is fixedly connected to each drive bar 5. The first rack 6 are symmetrically installed. Each first rack 6 is slidably connected to the interior of the outer cage 2. Two gears 7 are rotatably connected inside the outer cage 2. The gears 7 are symmetrically installed. Two locking pieces 12 are rotatably connected inside the outer cage 2. Each locking piece 12 corresponds to one gear 7. Each gear 7 corresponds to one gear 7. The first rack 6 is engaged with the outer cage 2. The outer cage 2 is equipped with a hanging cage 8. The hanging cage 8 is slidably connected to the slide rail inside the outer cage 2. The hanging cage 8 is connected to the lifting device inside the outer cage 2, so that the lifting device can drive the hanging cage 8 to move vertically inside the outer cage 2. Two second racks 9 are fixedly connected to the outer surface of the hanging cage 8. The second racks 9 are symmetrically installed. Each second rack 9 corresponds to a gear 7. When the hanging cage 8 moves downward, the hanging cage 8 drives the second racks 9 to move downward, so that the second racks 9 and gears 7 are engaged. The second racks 9 drive the gears 7 to rotate. The gears 7 drive the first rack 6 to slide. The first rack 6 drives the drive bar 5 to slide. The drive bar 5 drives the protective door 3 to rotate and open through the support rod 4. When the hanging cage 8 moves upward, the second racks 9 drive the gears 7 to reverse. The gears 7 drive the first rack 6 and drive bar 5 to slide in opposite directions, so that the drive bar 5 drives the protective door 3 to rotate and close through the support rod 4.

[0025] Please see Figure 3 , 4 Each locking piece 12 has a tooth 13 fixedly connected to one end, and each tooth 13 meshes with the corresponding gear 7. The locking piece 12 hinders the rotation of the gear 7 through the tooth 13, thereby limiting the movement of components such as the first rack 6.

[0026] Please see Figure 3 , 4 The outer cage 2 has two fixed connections inside, with the blocks 10 installed symmetrically. Each block 10 corresponds to a locking piece 12. The outer cage 2 also has two fixed connections inside, with the blocks 11 installed symmetrically. Each locking piece 11 corresponds to a locking piece 12. The blocks 10 and locking pieces 12 limit the rotation of the locking pieces 12.

[0027] Please see Figure 2 , 34. Two baffles 19 are fixedly connected to the outer surface of the cage 8. Each baffle 19 corresponds to a clamp 12. The baffles 19 are installed symmetrically. When the cage 8 moves downward, the cage 8 drives the clamp 12 to rotate through the baffles 19, so that the teeth 13 disengage from the gear 7.

[0028] Please see Figure 3 , 4 Each clip 12 has an arc-shaped rod 14 fixedly connected to its outer surface. The center of the arc of the arc rod 14 is located on the rotation axis of the clip 12. The other end of each arc rod 14 is located inside the corresponding positioning block 11. A first spring 15 is sleeved on the outer surface of each arc rod 14. One end of the first spring 15 is in contact with the outer surface of the clip 12, and the other end of the first spring 15 is in contact with the outer surface of the positioning block 11.

[0029] Please see Figure 2 , 5 6. Several damping rods are fixedly connected to the lower surface of the base plate 16. The damping rods are used to buffer and reduce the impact force generated by the descent of the cage 8. A second spring 20 is sleeved on the outer surface of each damping rod. The top of each second spring 20 is in contact with the lower surface of the base plate 16, and the bottom of each second spring 20 is in contact with the inner bottom wall of the base 1.

[0030] Please see Figure 2 , 5 6. Four support bars 17 are rotatably connected to the lower surface of the base plate 16. Each support bar 17 is rotatably connected to a slider 18 at the other end. Each slider 18 is slidably connected to the inner bottom wall of the base 1. The support bars 17 and sliders 18 provide auxiliary support for the base plate 16.

[0031] The implementation principle of the bottom cage of a high-rise elevator according to an embodiment of this application is as follows: When the cage 8 descends, the cage 8 drives the stop bar 19 and the second rack 9 to move downwards. The stop bar 19 drives the locking piece 12 to rotate, the first spring 15 is compressed, and the teeth 13 disengage from the gear 7. Subsequently, the second rack 9 meshes with the gear 7 and drives the gear 7 to rotate. The gear 7 drives the first rack 6 to slide, and the first rack 6 drives the drive bar 5 to slide. The drive bar 5 drives the protective door 3 to rotate and open through the support rod 4. When the bottom of the cage 8 falls to the upper surface of the bottom plate 16, the support... The bar 17 drives the slider 18 to slide, the damping rod retracts, and the second spring 20 is compressed, thereby reducing the shock on the base plate 16 and the cage 8. When the cage 8 rises, the cage 8 drives the second rack 9 and the stop bar 19 to move upward. The second rack 9 drives the gear 7 to reverse, the gear 7 drives the first rack 6 to slide in the opposite direction, the first rack 6 drives the drive bar 5 to slide, and the drive bar 5 drives the protective door 3 to rotate and close through the support rod 4. Then the stop bar 19 disengages from the locking piece 12, the first spring 15 pushes the locking piece 12 to reset, so that the teeth 13 and the gear 7 resume meshing.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
