Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unmanned elevator protection technology, specifically a protective device for elevator inlet and outlet. Background Technology
[0002] In modern construction, construction elevators are core equipment for vertical transportation, widely used for the efficient transport of materials and personnel. However, the design of the inlet and outlet areas of traditional construction elevators has significant shortcomings, mainly manifested in poor structural stability, inaccurate height, and inadequate protection. In existing technologies, the inlet and outlet are often constructed using simple support frames or temporary materials, leading to height mismatches, uneven surfaces, and large gaps when docking with the elevator car. This not only affects the smooth entry and exit of material carts and personnel but may also cause safety hazards such as tipping over or jamming. Furthermore, the lack of effective protective devices and safe anti-slip platforms poses a risk of falls or collisions to construction workers during operation.
[0003] Meanwhile, with the gradual promotion of driverless construction elevator technology, higher adaptation requirements are placed on the material inlet and outlet areas, including structural stability, precise height adjustment, a flat transition platform, and effective protective measures. This requires the outlet device to achieve seamless connection between the elevator car and the floor slab, providing sufficient structural strength and load-bearing capacity to ensure no displacement or deformation under long-term vibration and heavy load. Furthermore, the external safety gate must work synchronously with the elevator system to ensure smooth opening and closing of the safety gate, eliminate jamming, and guarantee the normal operation of the system. Utility Model Content
[0004] To address the issues of poor structural stability, inaccurate height, and inadequate protection at the feed and discharge ports of existing construction elevators, which fail to meet the requirements for efficient operation and safety protection of unmanned construction elevators, this utility model provides a protective device for the feed and discharge ports of elevators.
[0005] This utility model is achieved through the following technical solution:
[0006] A protective device for the feed inlet and outlet of an elevator includes a basement floor slab, a basement floor top slab, a safety door for the outer perimeter fence of the construction elevator on the ground floor, and an elevator car. The basement floor slab and the basement floor top slab are arranged opposite to each other. A positioning channel steel is provided on the basement floor top slab, the positioning channel steel including a first channel steel, a second channel steel, and a third channel steel. The first channel steel is fixed to the basement floor top slab with bolts, the second channel steel and the third channel steel are arranged on the first channel steel, and a gap is provided between the second channel steel and the third channel steel for the passage of the safety door for the outer perimeter fence of the construction elevator on the ground floor. The first channel steel is fixed to the basement floor top slab with bolts. A concrete layer of the same height as the positioning channel steel is provided on the upper part of the positioning channel steel. A checkered steel plate that matches the feed inlet of the elevator car is provided on the concrete layer.
[0007] A further improvement of this utility model is that it also includes a protective net around the construction elevator, the bottom of which is connected to the basement floor slab, and the two sides of which are respectively connected to the safety door of the outer fence of the construction elevator on the ground floor and the elevator car.
[0008] A further improvement of this utility model includes a standardized column, which is installed on the working surface via a concrete column pier. Standardized construction elevator safety doors and standardized guardrails are provided on both sides of the standardized column. The standardized construction elevator safety doors and standardized guardrails are connected to the standardized column via fixed pins.
[0009] A further improvement of this utility model is that a walkway plate is also provided inside the elevator car, and the walkway plate is connected to the elevator car by a screw.
[0010] A further improvement of this utility model is that the patterned steel has a length of 6 meters, a width of 1 meter, and a thickness of 2.5 millimeters.
[0011] A further improvement of this utility model is that the height of the concrete layer is 7cm.
[0012] A further improvement of this utility model is that the second channel steel and the third channel steel are welded to the first channel steel on three sides.
[0013] A further improvement of this utility model is that the cross-sectional height of the first channel steel is 160mm; the cross-sectional height of the second channel steel is 140mm; and the cross-sectional height of the third channel steel is 100mm.
[0014] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: By setting positioning channel steel on the top slab of the first basement level and pouring a concrete layer of the same height above the channel steel, and simultaneously laying patterned steel that matches the elevator car inlet on the concrete layer, a stable, flat, and non-slip discharge outlet transition platform is formed. A gap is provided between the second and third channel steels for the passage of the safety door of the construction elevator's outer perimeter fence on the ground floor. This ensures smooth passage of the safety door when opening and closing, effectively avoiding jamming caused by structural interference, ensuring the safety and stability of the construction elevator during operation, and improving the efficiency of materials and personnel entering and exiting the elevator car.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0025] like Figure 1-7As shown, this utility model discloses a protective device for the material inlet and outlet of an elevator. The elevator inlet protective device can be used when the elevator foundation is located below the basement floor. The outlet protective device is suitable for unmanned elevators. The elevator inlet protective device includes a basement floor 1, a basement floor top 2, a safety door 3 for the outer perimeter of the ground floor construction elevator, and an elevator car 4. The basement floor 1 and the basement floor top 2 are arranged opposite each other. In use, the basement floor 1 and the basement floor top 2 form the load-bearing space for the elevator outlet. Together with the safety door 3 for the outer perimeter of the ground floor construction elevator and the elevator car 4, they ensure the safe entry and exit of materials and personnel at the inlet and outlet, while also meeting the normal operation requirements of the unmanned construction elevator. Positioning channel steel is provided on the basement floor top 2, including a first channel steel 5, a second channel steel 6, and a third channel steel 7. The first channel steel 5 is fixed to the basement floor top 2 with bolts, and the second channel steel 6 and the third channel steel 7... The first channel steel 5 is mounted on the first channel steel 5, and a gap is provided between the second channel steel 6 and the third channel steel 7 for the passage of the safety door 3 of the outer fence of the construction elevator on the ground floor. The first channel steel 5 is fixed to the top plate 2 of the first basement floor with bolts to form a basic frame. The second channel steel 6 and the third channel steel 7 are located above the first channel steel 5 to provide structural reinforcement and height adjustment for the discharge port area, ensuring the stability and accuracy of the connection between the elevator car 4 and the discharge port of the floor slab. At the same time, the gap design between the second channel steel 6 and the third channel steel 7 allows for the smooth opening and closing of the safety door 3 of the outer fence of the construction elevator on the ground floor, ensuring the free movement of the elevator cage and the door body and avoiding jamming. A concrete layer with the same height as the positioning channel steel is provided on the upper part of the positioning channel steel. A checkered steel 8 that matches the feed port of the elevator car 4 is provided on the concrete layer. A concrete layer of the same height is poured above the positioning channel steel to make the surface of the discharge port flat and stable, preventing structural unevenness caused by the exposure of the positioning channel steel. The patterned steel 8, in conjunction with the feed inlet of the elevator car 4, forms a non-slip, flat transition platform, ensuring that material carts and personnel can safely and smoothly enter and exit the elevator car 4. The protective device at the discharge port is installed on one side of the construction building. The width of the protective device is determined based on the distance between the driverless elevator car and the construction building. The protective device can use template materials or steel mesh and is fixed to the building with expansion bolts.
[0026] It also includes a protective netting 9 around the construction elevator. The bottom of the protective netting 9 is connected to the basement floor 1, and the two sides of the protective netting 9 are respectively connected to the safety door 3 of the outer fence of the construction elevator on the ground floor and the elevator car 4. The protective netting 9 provides all-round protection for the elevator discharge area. The bottom is fixed to the basement floor 1 to ensure the stability of the protective netting 9. The two sides are connected to the safety door 3 of the outer fence of the construction elevator on the ground floor and the elevator car 4 to form a closed protective space to prevent personnel and materials from falling or accidentally colliding, thereby improving the safety of elevator operation and the construction site.
[0027] It also includes a standardized column 10, which is installed on the working surface (indoor balcony) via concrete column bases 11. Standardized construction elevator safety doors 12 and standardized guardrails 13 are provided on both sides of the standardized column 10. The standardized construction elevator safety doors 12 and standardized guardrails 13 are connected to the standardized column 10 via fixing pins 14. The standardized column 10 is stably supported on the working surface by the concrete column bases 11, providing a vertical support point. The standardized construction elevator safety doors 12 and standardized guardrails 13 installed on both sides are connected to the column via fixing pins 14, ensuring that the safety doors and guardrails can be quickly installed and disassembled, and effectively sealing the discharge port when the elevator is not stopped to prevent accidental falls.
[0028] The elevator car 4 is also equipped with a walkway 15, which is connected to the elevator car 4 by a screw 16. The walkway 15 is securely connected to the elevator car 4 by the screw 16. When the elevator car 4 stops, the walkway 15 can be flipped down to be flush with the checkered steel 8, filling the gap between the car and the discharge port, forming a safe and continuous passage, which facilitates the safe passage of material vehicles and personnel.
[0029] The patterned steel 8 is 6 meters long, 1 meter wide, and 2.5 millimeters thick, providing a non-slip, wear-resistant, and flat working surface in the discharge area, enhancing the safety and stability of materials and personnel entering and exiting.
[0030] The concrete layer is 7cm high, which effectively improves the overall strength and durability of the discharge port area.
[0031] The second channel steel 6 and the third channel steel 7 are welded to the first channel steel 5 on three sides. By welding on three sides, the second channel steel 6 and the third channel steel 7 are firmly connected to the first channel steel 5, ensuring the overall structural stability between the channel steels, increasing the load-bearing capacity of the discharge port area, and preventing vibration or displacement.
[0032] The first channel steel has a cross-sectional height of 160mm; the second channel steel has a cross-sectional height of 140mm; and the third channel steel has a cross-sectional height of 100mm. The first, second, and third channel steels with different cross-sectional heights form a stepped reinforcement frame, providing load-bearing requirements and height matching for different parts, and meeting the structural stability and height docking requirements of the construction elevator discharge port area.
