Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology for building engineering, and in particular to a retractable horizontal protection device for openings. Background Technology

[0002] During construction, various openings in floor slabs are often reserved in building structures for subsequent material transportation, equipment hoisting, or pipeline laying. To prevent workers from falling or materials from accidentally dropping, these openings need to be effectively protected. Existing methods of opening protection mostly involve simple coverings or fixed railings, which, while providing some protection, suffer from problems such as high structural rigidity, inconvenience in use, and inability to open and close quickly.

[0003] Especially in the construction of high-rise buildings, openings need to be opened and closed frequently to meet the needs of material transportation. Traditional fixed protective devices often require manual disassembly or relocation, which is labor-intensive and poses significant safety hazards. In addition, although some telescopic devices have opening and closing functions, they mostly rely on manual operation, resulting in low efficiency, poor synchronization, and unstable operation, making it difficult to meet the dual requirements of efficiency and safety in modern construction.

[0004] For example, patent number CN209907983U describes a horizontal opening protection device, including several opposing brackets arranged on both sides of the horizontal opening. Each bracket includes an L-shaped mounting portion for fixed installation on the horizontal opening. A grooved receiving portion is fixedly installed on one side plate of the mounting portion, and bolt mounting holes are provided on the side plate. The brackets are fixedly installed on both sides of the horizontal opening by bolts. A support rod is installed above the receiving portion of each opposing bracket, and a cover plate covering the horizontal opening is supported on the support rod. This utility model eliminates the need for steel pipe scaffolding and timber paving, significantly reducing the utilization rate of steel pipes. Moreover, the horizontal opening installation of this device is independent of the floor height, reducing installation costs. This utility model is applicable to the field of building engineering safety equipment technology. While the above technical solution can protect the opening, it cannot enable the vertical transport of materials through the opening, failing to meet the needs of material transportation. To meet transportation requirements, the protective device needs to be manually removed to realize the function of transporting materials through the opening, which is extremely inconvenient to use.

[0005] To address the aforementioned problems, this utility model provides a retractable horizontal protection device for openings that is structurally stable, easy to operate, and electrically driven. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a retractable horizontal protection device for openings.

[0007] The purpose of this utility model is achieved as follows: a retractable horizontal protective device for openings includes a protective net, with sliding rods symmetrically arranged on the left and right sides of the protective net, and multiple sliding rings that can slide back and forth on the sliding rods. The sliding rings are evenly connected to the left and right sides of the protective net, and a sliding block is provided at the front of each sliding rod. The sliding block can move back and forth along the sliding rod, and the sliding block is fixedly connected to the sliding ring on the front side. The sliding block drives the sliding ring on the front side to move back and forth.

[0008] Furthermore, the last slip ring at the rear of the slide rod is fixedly connected to the slide rod.

[0009] Furthermore, a support frame is provided at both the front and rear ends of the slide rod, and a support plate is provided at the bottom of the support frame, which is fixed to the ground.

[0010] Furthermore, the sliding block is connected to a driving mechanism, which drives the sliding block to move back and forth along the slide rod.

[0011] Beneficial effects: This utility model has the following technical effects when used:

[0012] 1. Scalability: Through the cooperation of sliding rod and sliding ring structure, the protective net can be extended and retracted along the sliding rod direction, and the opening size can be flexibly adjusted according to construction needs, which not only ensures the flexibility of operation, but also meets the protection needs under different working conditions; that is, the material is conveniently hoisted up and down, and the horizontal protection of the opening can be opened and restored.

[0013] 2. High degree of automation: The drive motor drives the rotating rod, and the rollers and transmission belt realize the synchronous movement of the sliding block, thereby driving the protective net to unfold or retract. The operation is convenient and quick, improving construction efficiency and suitable for occasions that require frequent opening and closing of openings.

[0014] 3. Stable structure and safe use: The sliding rod is equipped with fixed support frames and support plates at the front and rear, and the overall structure is firmly fixed and suitable for different types of building openings; the connecting rod is set to separate the protective net from the sliding ring, avoiding material damage or structural failure caused by direct friction, thus improving service life and safety; the horizontal protection can be opened and closed without people entering the facade protection, which solves the risk of falling from height when people enter the open opening.

[0015] In summary, this device has good adaptability, safety and practicality, and is particularly suitable for edge protection and opening protection in high-rise building construction, and has broad prospects for promotion and application. Attached Figure Description

[0020] Example 1, such as Figure 1-2 As shown, the purpose of this utility model is achieved as follows: A retractable horizontal protective device for openings includes a protective net 2. Sliding rods 8 are symmetrically arranged on the left and right sides of the protective net 2. Multiple sliding rings 9 are mounted on the sliding rods 8 and are evenly connected to the left and right sides of the protective net 2. A sliding block 10 is provided at the front of each sliding rod 8. The sliding block 10 can move back and forth along the sliding rod 8 and is fixedly connected to the sliding ring 9 on the front side. The sliding block 10 drives the sliding ring 9 on the front side to move back and forth. A connecting rod 13 is fixedly provided on the outer side of the sliding ring 9, and the outer end of the connecting rod 13 is connected to the protective net 2.

[0021] The last slip ring 9 at the rear of the slide rod 8 is fixedly connected to the slide rod 8. Support frames 11 are provided at both the front and rear ends of the slide rod 8, and support plates 12 are provided at the bottom of the support frames 11, with the support plates 12 fixed to the ground. The sliding block 10 is connected to a drive mechanism, which drives the sliding block 10 to move back and forth along the slide rod 8. The drive mechanism includes two parallel rotating rods 1, which can rotate. Rollers 3 are symmetrically fixed on both sides of each rotating rod 1. A transmission belt 7 is provided on each of the front and rear rollers 3 corresponding to the front and rear rotating rods 1, and the sliding block 10 is fixed to the transmission belt 7.

[0022] The rotating rod 1 has rotatable support frames 5 at both ends. Support plates 4 are fixed to the bottom of the support frames 5 and are fixed to the ground. A drive motor 6 is installed at the left end of the rotating rod 1 on the front side. The drive motor 6 drives the rotating rod 1 to rotate and is fixed to the support frame 5.

[0023] In use, the protective net 2 of this device is placed above the building opening, and the support plate 12 and the support plate 4 are fixed at the four corners of the building opening. When it is necessary to open the building opening to load or unload building materials, the drive motor 6 is controlled to rotate. The drive motor 6 drives the rotating rod 1 to rotate, and then the roller 3 rotates. When the roller 3 rotates, it drives the transmission belts 7 on the left and right sides to rotate, and at the same time, it drives the sliding block 10 to move back and forth along the sliding rod 8. That is, when it is necessary to open the protective net 2, the sliding block 10 moves backward, driving the front sliding ring 9 to move backward along the sliding rod 8. During the backward movement of the sliding ring 9, it drives the rear sliding ring 9 to move backward along the sliding rod 8 through compression, thereby driving the protective net 2 to retract backward and opening the building opening.

[0024] When it is necessary to close the building opening, the drive motor 6 is controlled to rotate the transmission belt 7, which in turn resets the sliding block 10. A connecting rod 13 is provided to prevent the protective net 2 from being directly connected to the slip ring 9 via ropes, which would cause the slip ring 9 to become rough inside, leading to friction between the sliding rod 8 and the slip ring 9 during relative movement, potentially causing breakage at the connection and creating a safety hazard. The drive motor 6 in this application is prior art and only needs to achieve the required function; it will not be described in detail here.
