Description

Technical Field

[0001] This invention relates to elevators, and more particularly to a protective panel structure for elevators. Background Technology

[0002] In the past, construction site elevators were used to transport building materials, equipment, and personnel. The elevators were then built into the shafts as construction neared completion, increasing both building completion time and material costs. The duplex elevator technology, designed to address these issues, was developed to address these problems. During construction, as the building progresses through its floors, elevator cars are gradually added to the shafts via temporary machine rooms, expanding the elevator's service range. Once the building reaches its top floor, only final adjustments are needed to complete the elevator construction, significantly reducing completion time and saving materials. Furthermore, construction site elevators are typically slow, while duplex elevators can be 4-6 times faster, resulting in a substantial improvement in construction efficiency.

[0003] The elevators were installed in the early stages of construction (when the civil engineering was still at the lower floors) and were temporarily put into use as equipment to transport construction workers (and construction materials). As the civil engineering construction continued and the building height gradually increased, the elevator machine room was raised to a higher position to increase the maximum number of floors it could serve, allowing it to serve more floors.

[0004] The elevator, based on a steel platform, has its temporary machine room and highest service floor located on the steel platform, with the highest service floor being the top of the steel platform. As construction progresses and the building height gradually increases, the elevator's machine room and highest service floor will be raised to a higher position along with the steel platform, increasing the height of the highest service floor and the number of floors that can be served.

[0005] like Figure 1 As shown, a duplex elevator based on a steel platform typically includes an elevator machine room 11 located on the steel platform 8, machine room guide rails fixed in the space at the bottom of the elevator machine room, guide rails installed in the completed shaft, guide rail supports, a car 15, a counterweight 21, protective plates, and a traction wire rope sheave system. When the building is raised, the steel platform 8 first moves the elevator machine room 11 upwards, and the corresponding flexible components (including cables, wire ropes, etc.) extend. Then, the telescopic platform located on top of the car 15 is used as an installation platform to install the guide rails, guide rail supports, and other shaft components.

[0006] A key characteristic of escalator elevators based on steel platforms is that they serve not only the floors corresponding to the shaft but also the space at the bottom of the elevator machine room 11 on the steel platform 8. In escalator elevators, there is often a gap between the top of the building shaft and the bottom of the elevator machine room on the steel platform—an open opening at the top of the shaft. While this opening can usually be closed through engineering means, it inevitably cannot be closed during certain operations (such as escalation). After the escalation, operators sometimes need to operate from the top of the car 15, and the presence of this open opening poses a safety risk to them. Furthermore, to prevent objects from falling and damaging critical elevator components, a protective plate should be installed between the traditional shaft (building shaft) and the steel platform to protect property and lives. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0062] The front car side partition 4 includes a front car partition 4a and a front car partition drive unit 4b.

[0063] The front car partition 4a is pivotally connected to the hoistway wall via left and right forward car partition pivots, and the car guide rail 13a corresponds to the rear of the front car partition 4a when it is laid flat.

[0064] The rear car side partition 3 includes a rear car partition 3a and a rear car partition drive unit 3b.

[0071] The protective plate structure of the elevator in Embodiment 1 is installed at the top of the elevator shaft (between the highest and second-highest service floors). Depending on the arrangement of the elevator components, the counterweight partition 2a of the counterweight-side partition block 2, the rear car partition 3a of the rear car-side partition block 3, and the front car partition 4a of the front car-side partition block 4 are vertically opened or horizontally closed via rotational movement. The control unit is related to the elevator's operation. Before the elevator car or counterweight and other moving parts pass through the protective plate structure, the control unit controls the counterweight partition 2a, the rear car partition 3a, and the front car partition 4a to open, opening the movement channel for the elevator car and counterweight and other moving parts.

The protective plate structure of the elevator in Embodiment 1 facilitates flexible control of the opening and closing of the movement channels of the elevator car and counterweight and other moving parts. While ensuring the normal operation of the moving parts of the elevator, it reduces the impact of foreign objects falling into the shaft on the elevator, and better protects the important parts of the elevator and the operators in harsh engineering environments.

[0085] The rear car partition 3a protrudes from the edge away from its axis of rotation. The protruding block overlaps with the fixed partition block away from its axis of rotation. Under the action of the protruding block, the rear car partition 3a cannot rotate downward from the closed state.

[0086] In the protective plate structure of the elevator in Embodiment 3, a stop member is formed directly below the far axis of the horizontally placed rear car partition 3a, the horizontally placed counterweight partition 2a, and the horizontally placed front car partition 4a, so that the partition cannot rotate downwards, thereby preventing the partition from rotating excessively and preventing the impact on the drive unit motor when heavy objects fall on the partition.
