Description

Technical Field

[0001] The utility model relates to the technical field of safety protection of building material transfer openings, in particular to a material transfer opening protection device used in building construction. Background Art

[0002] In housing construction, material transfer ports are often used in the construction of complex structures such as high-rise buildings and large commercial complexes. Through the material transfer ports, construction workers can quickly transport heavy materials such as steel bars and concrete to each floor, greatly improving construction efficiency and safety. In addition, the material transfer ports can also be used for equipment installation and maintenance to ensure smooth construction. However, due to the long construction period of high-rise buildings, the upper and lower floors need to be worked on simultaneously. Therefore, the material transfer ports need to be blocked in a timely manner to prevent debris and other construction debris generated during upper-level construction from falling through the material transfer ports and endangering the safety of people and equipment on the lower floors.

[0003] For example, the utility model patent with the authorization announcement date of 2024.05.17 and the authorization announcement number CN 220978918 U discloses a material transfer port hole protection device, which relates to the field of construction equipment. The technical solution is that it includes two parallel mounting parts and a cover plate rotatably connected to the two mounting parts respectively. The mounting part includes a screw rod, a lower clamping arm is slidably set on the thread of the screw rod, a fixing frame is fixedly set on one side of the screw rod, an adjuster is rotatably set on the upper part of the fixing frame, an upper clamping arm is rotatably set on the upper end of the screw rod, the middle part of the upper clamping arm is rotatably connected to the screw rod, and the side of the upper clamping arm facing away from the fixing frame is rotatably connected to the cover plate; the cover plate is rectangular, and a slide rail is fixedly set on one side of the cover plate, and two sliders are slidably set on the slide rail, and each slider is rotatably connected to one of the mounting parts through a hinge.

[0004] The feed port hole protection device provided by the aforementioned utility model patent can replace traditional wooden and steel covers, is easy to disassemble and recycle, and can be used in combination to protect feed ports of different lengths. However, there are still some shortcomings. First, it is only suitable for feed ports of a single width. If the feed port width is larger, arranging multiple feed port hole protection devices side by side cannot ensure the safety of passage. Second, the structure is complex and requires multiple clamping arms for clamping. The clamping arms are composed of a screw, a nut, a sleeve fixing frame, an adjuster guide groove, and other structures.

[0005] In summary, there is an urgent need to design a material transfer port protection device that is simple in structure and suitable for various sizes.

[0006] It should be noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or suggestion in any form that the above technical information constitutes prior art already known to those skilled in the art. Utility Model Content

[0011] Based on the above technical solution, as a preferred technical solution, the protective plate is rectangular or square, and at least two sleeves are spaced apart on each of the four sides of the protective plate, with the spacing between adjacent sleeves being greater than the length of the sleeve. This technical solution provides a further preferred structural design, designing the protective plate into a square or rectangular shape. By increasing the number of sleeves and optimizing the positional and assembly relationships between the sleeves, the convenience of splicing and expansion is further improved, the reliability of shielding and sealing the joints is enhanced, and the modular structural design and application effects are further enhanced.

[0013] Based on the above technical solution, as a preferred technical solution, at least one end of the grabbing pin is provided with a pin hole, to which a safety pin is connected. This technical solution improves the reliability of the positioning structure, and the use of the safety pin to lock the grabbing pin effectively prevents accidental disengagement of the grabbing pin. Furthermore, this technical solution provides two alternative technical solutions: one is to equip the grabbing pin with a safety pin only at one end, which facilitates disassembly; the other is to equip the grabbing pin with a safety pin at both ends, which provides higher reliability.

[0014] Based on the above technical solution, as a preferred technical solution, the safety pin is an O-type safety pin, a D-type safety pin, or a ball-end quick-release pin. This technical solution provides a variety of preferred safety pins. While locking the grabbing nail and preventing it from falling off the protective plate, the O-type safety pin, the D-type safety pin, and the ball-end quick-release pin can also prevent themselves from falling off. In addition, other types of safety pins or ordinary pins can also be used.

[0034] A material transfer port protection device for building construction, such as Figures 1 to 3As shown, it includes several protective plates 1, and adjacent protective plates 1 are connected by hinge structures 2 at the edges. Positioning structures 3 are also provided between adjacent protective plates 1. When adjacent protective plates 1 are spread out above the material transfer port 0, the positioning structures 3 are used to prevent the adjacent protective plates 1 from continuing to flip over. The number of protective plates 1 in this embodiment can be flexibly selected according to the on-site size of the material transfer port 0. Each protective plate 1 can be expanded in both the width direction and the length direction, and the expansion method and connection structure are very simple. One is hinged, and the other is locked. This embodiment not only expands the application through the hinge structure 2, but also is used to limit the freedom of the protective plate 1 perpendicular to the seam direction, and the positioning structure 3 is used to limit the rotation direction and the freedom parallel to the seam direction of the hinge structure 2. It is convenient for assembly and expansion to expand the scope of application, and it is also convenient for assembly, disassembly and turnover use, and it is convenient and reliable for positioning.

[0035] Based on the above embodiment, as a preferred embodiment, the hinge structure 2 includes a plurality of sleeves 2-1 spaced around the perimeter of the protective plate 1. The sleeves 2-1 between adjacent protective plates 1 are connected by a pin 2-2. This embodiment provides an optimized structural design for the hinge structure. The sleeves 2-1 are easy to source and weld to the protective plate 1, and can also fill and conceal the seams between adjacent protective plates 1.

[0036] Based on the above embodiment, as a preferred embodiment, the protective plate 1 is rectangular or square, with at least two sleeves 2-1 spaced apart on each of the four sides of the protective plate 1, and the spacing between adjacent sleeves 2-1 is greater than the length of the sleeve 2-1. This embodiment provides a further preferred structural design, designing the protective plate 1 into a square or rectangular shape. By increasing the number of sleeves 2-1 and optimizing the positional and assembly relationships between sleeves 2-1, the convenience of splicing and expansion is further improved, the reliability of shielding and sealing the joints is enhanced, and the modular structural design and application effects are further enhanced.

[0037] Based on the above embodiment, as a preferred embodiment, the positioning structure 3 comprises positioning holes 3-1 defined in the protective plates 1. Positioning holes 3-1 in adjacent protective plates 1 are connected by U-shaped pins 3-2. This embodiment utilizes the pins 3-2, which engage with the positioning holes 3-1, as the positioning structure 3 to lock and position adjacent protective plates 1. This structure is simple and versatile, further enhancing ease of use, assembly, and disassembly.

[0038] Based on the above embodiment, as a preferred embodiment, at least one end of the gripping pin 3-2 is provided with a pin hole 3-3, to which a safety pin 3-4 is connected. This embodiment improves the reliability of the positioning structure 3. The use of the safety pin 3-4 to lock the gripping pin 3-2 effectively prevents accidental disengagement of the gripping pin 3-2. Furthermore, this embodiment provides two alternative embodiments: one in which the safety pin 3-4 is installed on only one end of the gripping pin 3-2, which facilitates easy disassembly; the other in which the safety pin 3-4 is installed on both ends of the gripping pin 3-2, which offers greater reliability.

[0039] Based on the above embodiment, as a preferred embodiment, the safety pin 3-4 is an O-type safety pin, a D-type safety pin, or a ball-end quick-release pin. This embodiment provides a variety of preferred safety pins 3-4. While locking the catch pin 3-2 and preventing it from falling off the protective plate 1, the O-type safety pin, the D-type safety pin, and the ball-end quick-release pin can also prevent themselves from falling off. Other types of safety pins or ordinary pins may also be used.

[0040] On the basis of the above embodiment, as a preferred embodiment, the positioning structure 3 includes a stop block 3-5 provided on the edge of the protective plate 1. When adjacent protective plates 1 are connected by the hinge structure 2 and spread out flat, the stop block 3-5 abuts between the adjacent protective plates 1. On the basis of the above embodiment, this embodiment adds a stop block 3-5, which can work together with the gripping pin 3-2 to fully ensure the reliability of the unfolding and laying of the protective plate 1. Among them, the gripping pin 3-2 is plugged into the positioning hole 3-1, which is an active positioning structural design and a positioning design that requires manual operation; while the positioning method of the stop block 3-5 is a passive locking positioning, and is used to assist the reliability of the positioning of the gripping pin 3-2.

[0041] Without the stopper 3-5, the gripping pin 3-2 and the protective plate 1 are not perpendicular, but may be at a certain angle. The rotational stability between adjacent protective plates 1 depends entirely on the insertion position and structural strength of the gripping pin 3-2. The gripping pin 3-2 is subject not only to shear forces but also significant torsional forces. This can lead to two significant problems: first, stress fatigue in the gripping pin 3-2, affecting its reliability; and second, bending deformation in the gripping pin 3-2, preventing it from fitting into the positioning hole 3-1. Therefore, the coupling of the stopper 3-5 and the gripping pin 3-2 fully ensures the reliability of the protection and extends the service life of the gripping pin 3-2.

[0042] On the basis of the above-mentioned embodiments, as a preferred embodiment, the cross section of the stop block 3-5 is a right-angled trapezoid, the right angle of the right-angled trapezoid is attached to the outer edge of the guard plate 1, and the oblique side is directed to the adjacent guard plate 1. The technical scheme adopted in this embodiment is that one side of the stop block 3-5 is directly connected with the guard plate 1, preferably by welding, and the other side of the stop block 3-5 is directly in contact with the top of the stop block 3-5 on the adjacent guard plate 1.

[0043] On the basis of the above-mentioned embodiments, as a preferred embodiment, the stop block 3-5 on one of the guard plates 1 is arranged in a spaced manner with the stop block 3-5 on the other guard plate 1 in the length direction of the guard plate 1 between the adjacent guard plates 1.

[0044] On the basis of the above-mentioned embodiments, as another preferred embodiment, the stop block 3-5 on one of the guard plates 1 is arranged in a spaced manner with the stop block 3-5 on the other guard plate 1 in the length direction of the guard plate 1 between the adjacent guard plates 1. The technical scheme adopted in this embodiment is that one side of the stop block 3-5 is directly connected with the guard plate 1, preferably by welding, and the other side of the stop block 3-5 is directly in contact with the top of the stop block 3-5 on the adjacent guard plate 1.

[0045] The above shows and describes the basic principle, main features and beneficial effects of the present application. The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
