[0033] Working Principle: During operation, the elevator enters frame 2, which is integrally formed by the bottom frame plate 41, side frame plate 42, and top frame plate 43, providing a stable installation benchmark for each protective component. It integrates the first protective device 3, the first sealing device 4, the second sealing device 5, the second protective device 6, and the side splicing protection devices to construct a comprehensive protection system. Specifically, the first protective device 3 drives the sliding door device 9 along the first sliding rail 10 and the second sliding rail 11 via an electric push rod 12, achieving automated opening and closing of the rear protection. Its integrally formed sliding door structure and precise guide rails ensure stable driving and smooth sliding, effectively improving the convenience and stability of the rear protection. The second protective device 6 drives the rotating pedal 27 to rotate via a rotary motor 29, and in conjunction with the anti-slip groove 32 and rubber buffer pad 31, achieves flexible switching between internal protection and passage, while simultaneously improving... To enhance the safety of personnel stepping on the elevator, the first sealing device 4 and the second sealing device 5 are driven by the door opening motor 36 to rotate the rotating door frame 35. Combined with the cross-shaped reinforcing frame 38 and the magnetic attraction structure, the front-end sealing is tight and the structure is strong, eliminating the front-end protection loopholes. The side splicing protection devices are fixed by the first connecting block 47 and the connecting device 44 of the elevator entry frame 2. They can be flexibly spliced ​​and expanded. Combined with the weight reduction holes 49 of the main protective plate 46, the side protection is maintained while achieving lightweighting. All components work together to achieve fully enclosed protection when the elevator has not arrived, synchronous opening for passage when it arrives, and automatic closing after passage. Ultimately, this achieves the technical effects of filling protection blind spots, improving operation convenience, enhancing protection stability and safety, and adapting to different elevator specifications, comprehensively solving the core pain points of existing building elevator protection.

[0035] First protective device 3: Installed at the rear end of the elevator entrance frame 2, responsible for rear-end protection, it consists of a sliding door device 9, a first sliding rail 10, a second sliding rail 11, an electric push rod 12, and a fixing hoop 13; the electric push rod 12 is fixed to the top frame plate 43 through the bottom push rod seat 19 and seat hole 20, and the drive end is connected to the sliding door device 9 through the fixing hoop 13, driving it to slide along the first sliding rail 10 and the second sliding rail 11 to realize the automatic opening and closing of the rear-end protection; the first sliding rail 10 and the second sliding rail 11 are both U-shaped, integrally formed by the first block 21, the second block 22, and the third block 23, and the surface fixing hole 24 is used for fixed installation; in the sliding door device 9, the door frame body 14, the first side slider 15, the second side slider 16, and the drive block 17 are integrally formed, the door mesh 18 realizes protection and isolation, and the slider and the guide rail cooperate to ensure smooth sliding.

[0036] The first sealing device 4 and the second sealing device 5 are symmetrically installed on the left and right sides of the front end of the elevator entry frame 2, with completely identical structures, and are responsible for front-end sealing and protection. They consist of a first rotating block 33, a second rotating block 34, a rotating door frame 35, a door opening motor 36, a door hinge 37, a reinforcing frame 38, and a protective net 39. The first rotating block 33 and the second rotating block 34 are welded to the front end of the elevator entry frame 2. The door opening motor 36 drives the door hinge 37 to rotate, which in turn drives the rotating door frame 35 to rotate, thus realizing the opening and closing of the front end. The reinforcing frame 38 is cross-shaped to enhance the strength of the rotating door frame 35. The protective net 39 provides isolation and protection. The positive magnetic block 40 on the inner side of the rotating door frame 35 cooperates with the negative magnetic block 45 of the elevator entry frame 2 to ensure a tight seal.

[0037] The second protective device 6 is installed inside the rear end of the elevator entrance frame 2 and is responsible for switching between internal protection and passage. It consists of a first rotating block 25, a second rotating block 26, a rotating pedal 27, a rotating shaft 28, and a rotating motor 29. The first rotating block 25 and the second rotating block 26 are distributed horizontally at equal intervals, and the inner side is equipped with a mounting block 30 and a fixing hole 24 for fixing the device. The rotating motor 29 drives the rotating shaft 28 to rotate, which causes the rotating pedal 27 to flip, realizing the switching between protection and passage. The surface of the rotating pedal 27 is provided with anti-slip grooves 32, and a rubber buffer pad 31 is installed at the bottom to improve the safety of use.

[0038] First side splicing protection device 7 and second side splicing protection device 8: symmetrically installed at the left and right ends of the elevator entry frame 2, with completely identical structures, responsible for side protection and expansion, consisting of main protective plate 46, first connecting block 47, and second connecting block 48; the first connecting block 47 is inserted into the connecting device 44 of the elevator entry frame 2 and fixed by bolts, and the second connecting block 48 is used for splicing and expansion of multiple sets of devices; weight reduction holes 49 are opened on the surface of the main protective plate 46 to balance protection strength and lightweight, and fixing holes 24 on the surface of the first connecting block 47 and the second connecting block 48 are used for fixed installation.

[0039] The core logic of the two schemes With "full-coverage protection + automated linkage" as its core, the elevator entry frame 2 integrates various labeled components to form a comprehensive protection layout of "front end + rear end + interior + sides". Electric push rods 12, door opening motors 36 and rotary motors 29 drive the corresponding protective components to achieve automated and coordinated operation of each device without manual operation. Through the integrated molding structure, magnetic attraction, and splicable design, the protection stability, sealing tightness and adaptability are ensured, completely solving the pain points of existing protection.

[0040] II. Technical Effects of Implementing this Solution After implementation, this solution will comprehensively optimize the floor protection effect of elevators in building construction, taking into account safety, convenience, and adaptability. The specific technical effects are as follows: 1. Fill in protection blind spots and achieve all-dimensional security protection. Through the coordinated operation of various components, a fully enclosed protection system is constructed: the elevator entry frame 2 serves as the basic framework, the first protective device 3 covers the rear end, the first sealing device 4 and the second sealing device 5 cover the front end, the second protective device 6 covers the internal rear end, and the first side splicing protection device 7 and the second side splicing protection device 8 cover both sides. This precisely fills the common blind spots in existing protection systems, such as the sides, front and rear ends of the elevator entry frame, eliminating safety hazards such as personnel falling and debris falling, and achieving full-dimensional, all-around safety protection.

[0041] 2. Achieve automated linkage to improve operational convenience and efficiency. By eliminating the manual operation mode of existing protective devices, the electric push rod 12 drives the moving door device 9, the door opening motor 36 drives the rotating door frame 35, and the rotating motor 29 drives the rotating pedal 27, realizing the automated operation of each protective component. When the elevator has not arrived, all devices close synchronously to form a fully enclosed protection. After the elevator arrives, all devices open synchronously to ensure smooth passage. After passage, they automatically close and reset without manual intervention, greatly improving the convenience of operation, reducing labor input, and improving construction efficiency.

[0042] 3. Enhanced protection stability and safety of use Structural stability: Multiple core components adopt an integrated molding design, such as the bottom frame plate 41, side frame plate 42, and top frame plate 43 of the elevator entry frame 2; and the door frame body 14 of the sliding door device 9. These components have high structural strength, are not easily deformed or loosened, and extend the service life of the equipment. Each component is fixed with bolts and magnetically attached to the positive magnetic block 40 and the negative magnetic block 45, ensuring a firm and tight installation and preventing the protective components from shifting or falling off.

[0043] Safety in use: The anti-slip groove 32 of the rotating pedal 27 increases friction, and the rubber buffer pad 31 acts as a buffer, reducing the impact and risk of slipping when people step on it; the protective nets 18 and 39 adopt an isolation design, which does not affect the view and can effectively prevent debris from falling and people from accidentally entering; the electric push rod 12, the door opening motor 36, and the rotary motor 29 of each drive component operate stably, avoiding problems such as jamming and malfunction, and ensuring safety in use.

[0044] 4. Improve adaptability and flexibility, balancing practicality and lightweight design. The first side splicing protection device 7 and the second side splicing protection device 8 can be flexibly spliced ​​with the elevator entry frame 2 through the first connecting block 47 and the connecting device 44. The protection range can be expanded according to the specifications of the construction elevator and the floor protection requirements, and can be adapted to different scenarios. The weight reduction hole 49 design of the main protective plate 46 reduces the weight of the components while ensuring the protection strength, making it easy to transport, install and debug, reducing the labor intensity of construction personnel, and taking into account both practicality and lightweight requirements.

[0045] 5. Comprehensively address existing technological pain points It completely solves the three core pain points of existing building elevator protection: First, it solves the problem of many blind spots through a fully enclosed layout; second, it solves the problems of inconvenient manual operation and poor linkage through an automated linkage design; and third, it solves the problems of insufficient protection stability and poor adaptability through a one-piece molding, magnetic attraction, and splicable structural design, comprehensively optimizing the user experience of building construction elevator floor protection and providing reliable protection for construction safety.

[0046] Regarding the application embodiment 1 of this solution: Another embodiment of the present invention has the same basic structure as the basic embodiment, except that: in the first protective device 3, the original electric push rod 12 and fixed hoop 13 driving structure is cancelled, and a servo motor, transmission gear and rack assembly are used as equivalent driving components. The servo motor is fixed to the top rear side of the top frame plate 43 of the elevator entry frame 2 by bolts. The rack is horizontally fixed along the top of the door frame 14 of the sliding door device 9. The transmission gear is keyed to the drive end of the servo motor and meshes with the rack. The forward and reverse rotation of the servo motor drives the gear and rack transmission to realize the automatic opening and closing of the sliding door device 9 along the first sliding rail 10 and the second sliding rail 11; in the second protective device 6, the original single-drive structure of single-sided rotating motor 29 and rotating shaft 28 is cancelled, and a double-drive electric hinge is used as equivalent driving component. The two sets of electric hinges are respectively installed on the inner side of the first rotating block 25 and the second rotating block 26, and the rotating pedal 27 is rotated. Both ends are fixedly connected to the rotating ends of two sets of electric hinges, and the dual drive components operate synchronously to realize the flipping and opening of the rotating pedal 27. At the same time, the anti-slip groove 32 on the surface of the rotating pedal 27 is replaced with an anti-slip texture integrally pressed from a patterned steel plate, and the rubber buffer pad 31 at the bottom is replaced with a polyurethane buffer pad. In the first sealing device 4 and the second sealing device 5, the positive magnetic block 40 on the inner side of the rotating door frame 35 and the negative magnetic block 45 on the elevator entry frame 2 are replaced with an electromagnetic lock assembly as an equivalent locking component. The electromagnetic lock body is installed on the front side of the bottom frame plate 41 and the top frame plate 43 of the elevator entry frame 2, and the latch is correspondingly installed on the inner side of the rotating door frame 35. In the closed state, the rotating door frame 35 is limited and fixed by electronic locking. The above-mentioned modified solutions do not deviate from the core inventive concept of the all-encompassing protection system and the automated collaborative linkage of multiple components of this invention, and can achieve the same all-dimensional protection effect as the basic embodiment, and all fall within the protection scope of this invention.

[0047] Regarding the application embodiment 2 of this solution: Another embodiment of the present invention, whose basic structure is consistent with the basic embodiment, the difference is that: in the elevator entry frame 2, the original integrally formed bottom frame plate 41, side frame plate 42, and top frame plate 43 are replaced with a segmented bolt-jointed modular structure. The bottom frame plate 41, side frame plate 42, and top frame plate 43 are all divided into 2-3 standard segments. Each segment end is provided with a connecting ear plate. Adjacent segments are fixedly joined by connecting ear plates and high-strength bolts. The overall size of the elevator entry frame 2 can be flexibly adjusted according to the width and height of the elevator opening on each floor. In the first side splicing protection device 7 and the second side splicing protection device 8, the original single-plate main protective plate 46 is replaced with a laterally telescopic sleeve-type protective plate structure. The main protective plate 46 is divided into an inner sleeve plate and an outer sleeve plate that are embedded in each other. The inner sleeve plate can slide laterally along the inner cavity of the outer sleeve plate to adjust the overall protective width. The first connecting block 47 is fixed to the outer end of the inner sleeve plate, and the second connecting block 48 is fixed to the outer end of the inner sleeve plate. Fixed to the outer end of the outer sleeve plate, the weight-reducing holes 49 are correspondingly opened on the surfaces of the inner sleeve plate and the outer sleeve plate; the electric push rod 12 of the first protective device 3 is replaced with a small electric cylinder with high thrust, the door opening motor 36 of the first sealing device 4 and the second sealing device 5 is replaced with a decelerated stepper motor, and the rotary motor 29 of the second protective device 6 is replaced with a forward and reverse decelerated motor. All driving components are adapted to the low-voltage DC power supply mode of the construction site. The above-mentioned modified schemes do not deviate from the core inventive concept of the fully enclosed protection system and the automated collaborative linkage of multiple components of this invention, and can achieve the same all-dimensional protection effect as the basic embodiment, and all fall within the protection scope of this invention.
