[0002] In the construction industry, construction workers usually need to wear safety belts and other safety devices to ensure their personal safety when working on edges. However, during the project construction process, especially in the secondary structure and decoration stage, due to considerations of construction progress, site conditions and cost control, workers are often faced with the situation of working without external scaffolding. In this case, workers often lack a reliable safety belt hanging fixed position when working at height, and there is a great risk of falling.

[0003] As disclosed in the patent document with the publication number CN202121211512.4, the utility model provides a safety belt hanging device for high-altitude edge operations, including a cylindrical tube and a baffle, the cylindrical tube is open at both ends, a hanging ring for hanging a safety belt is provided at one end of the opening of the cylindrical tube, the baffle is connected to the cylindrical tube through an axle rod, the two ends of the axle rod are fixedly connected to the cylindrical tube, the baffle can rotate around the axle rod, a pull rod for controlling the opening and closing of the baffle is hinged on the baffle, the baffle is controlled to rotate to close the baffle with the wall by controlling the operating end of the pull rod, the protective bolt is locked with the wall thickness according to the different thickness of the shear wall, after the protective bolt is taken out, the pull rod is pulled to retract the baffle, and it is quickly separated from the wall, and then the safety belt hanging device is taken out from the reserved hole. The utility model has a simple structure and low manufacturing cost, and the installation of the safety belt hanging device is realized on a single side of the wall, which is convenient for installation and disassembly, convenient to carry, and firmly connected to the wall, and has high safety. However, the tube body of the device cannot be adjusted according to the actual wall thickness on site. After processing and forming, if the outer rod body is too long, it is easy to form a cantilever end, which increases the risk of rod damage and makes the rod inconvenient to transport. In addition, the inner and outer devices of the device are integrated on the wall. If the safety device is partially damaged, the entire device will face replacement, which greatly increases the cost. Summary of the invention

[0007] The hollow steel pipes of the components are connected to form an integral safety device through the inner lining thread and the outer convex thread. The overall length of the device can be flexibly adjusted through the second hollow steel pipes of different modules to adapt to different wall thicknesses, and the modular design facilitates the rapid replacement of damaged components.

[0008] By inserting the built-in insertion rod into the hollow steel pipe of the safety device on the inner side of the wall, applying pressure at the end, squeezing the squeezing hammer to push the squeezing rod with gear patterns to generate displacement transmission, thereby driving the rotating steel plate to rotate and be fixed on the outer wall through the gear, thereby realizing a single-sided installation and fixing of the safety device.

[0010] Furthermore, a hollow steel pipe blocking plate is provided at the end of the first hollow steel pipe, and a return spring base and an extrusion rod passing hole for the extrusion rod with the gear pattern to pass through are respectively provided at diagonal positions thereof.

[0011] Furthermore, a return spring is installed on the return spring base, and the other end of the return spring is connected to the extrusion hammer for bearing the pressure of the built-in insertion rod.

[0013] Furthermore, one end of the rotating steel plate is circular and the other end is rectangular, the width is the same as the diameter of the first hollow steel pipe, and the thickness is 1 / 4 to 1 / 3 of the diameter of the first hollow steel pipe.

[0014] Furthermore, a steel plate clamp ring for internally attaching to the wall is welded at the end of the third hollow steel plate.

[0015] Furthermore, the built-in insertion rod also includes an insertion rod whose diameter is smaller than the inner diameter of the hollow steel pipe.

[0016] Furthermore, a suspension ring for hanging a safety belt or a steel wire rope is welded to the end of the insertion rod.

[0017] According to another aspect of the present invention, the present invention provides a method for using a combined edge working safety device, which is implemented by applying the above-mentioned combined edge working safety device, and the specific implementation steps are as follows:

[0018] S100: Preliminary preparation: Process the safety device components into corresponding size specifications according to the drawings and modular standards, and transport the processed components to the site;

[0019] S200: On-site assembly and installation: According to the thickness of the on-site wall, connect the second hollow steel with different moduli into the required length of the through-wall component, and assemble the three major components of the wall outer side fixing component, the through-wall component, and the wall inner side fixing component into an integral device through the bolt thread; pass the assembled safety device through the reserved hole in the wall, ensure that the steel plate clamp ring on the wall inner side fixing component is attached to the inside of the wall, and fixed inside the wall;

[0020] S300: Fixing on the outside of the wall: insert the built-in plug rod into the hollow steel tube of the wall penetration safety device, apply pressure to the other end of the built-in plug rod, and rotate the built-in plug rod to clamp the nail on the built-in plug rod into the L-shaped card slot of the fixing component on the inside of the wall.

[0023] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0024] 1. The wall-penetrating rod of the combined edge operation safety device of the present invention is modularly designed by a step of 50 mm thickness of the building wall, and can be produced in lengths of 50 mm, 100 mm, 200 mm, etc. It is processed in a factory and can be spliced ​​according to the actual situation on site when in use, so that the products of the manufacturer or rental manufacturer have multiple applicability in the construction industry, and the flexibility and applicability of the device are improved;

[0025] 2.

[0040] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a combined edge operation safety device, including a wall outer side fixing component, a wall penetrating component, a wall inner side fixing component and a built-in plug rod, the wall outer side fixing component includes a rotating steel plate 1, a gear 2 fixed thereon, an extrusion rod 3 with a gear pattern and a first hollow steel pipe 4 with an external convex thread opening 5 at the end; the wall penetrating component is a second hollow steel pipe 14 with a different module, the tail of which is made into an inner lining thread opening 15, and the end is made into an external convex thread opening 5; the wall inner side fixing component includes a third hollow steel plate 21 with an L-shaped slot 17 cut out at the end.

[0042] The first hollow steel pipe 4 of the wall outer side fixing component, the second hollow steel pipe 14 of different modulus of the wall-penetrating rod, and the third hollow steel plate 21 with L-shaped slot 17 of the wall inner side fixing component are assembled into an integral device through the threaded buckle, and the overall length of the device is controlled by the hollow steel pipe 14 of different modulus of the wall-penetrating rod to adapt to different wall thicknesses. The length of the device can be flexibly adjusted to adapt to shear walls of different thicknesses, thereby improving the applicability and flexibility of the device, and the damaged segment hollow steel plate can be replaced, reducing construction costs. By inserting the built-in plug rod into the device on the inner side of the wall and applying pressure, the extrusion rod 3 with gear pattern pushes the gear 2 on the rotating steel plate 1 to rotate, thereby driving the rotating steel plate 1 to rotate and be fixed on the outer wall, thereby realizing the single-sided installation and fixing of the safety device, avoiding the installation of the safety device on the air side, and reducing the risk of operators.

[0043] Furthermore, if Figure 1-4As shown, the outer wall fixing component includes a rotating steel plate 1 on which a gear 2 is fixed, an extrusion rod 3 with a gear pattern matching the gear 2, a first hollow steel pipe 4 with an outer convex thread mouth 5 made at one end, a fixing anchor 6, a return spring 7, a return spring 8, a hollow steel pipe blocking plate 9, an extrusion hammer 10, a return spring base 11, an extrusion rod through hole 12 and a fixing plate 13; the other end of the first hollow steel pipe 4 is welded with the fixing plate 13, and the fixing plate 13 is a rectangular parallelepiped steel plate, the width of which is the same as the diameter of the hollow steel pipe 4, and the thickness is 1 / 4 to 1 / 3 of the diameter of the first hollow steel pipe 4. , which is vertically welded to the center of the first hollow steel tube 4, with the short side parallel to the plane of the end of the first hollow steel tube 4, and the long side perpendicular to the plane of the end of the first hollow steel tube 4. The hollow steel tube blocking plate 9 is arranged at the bottom of the first hollow steel tube 4, and the diagonal positions of the return spring base 11 for installing the return spring 8 and the extrusion rod through hole 12 for facilitating the extrusion rod 3 with gear pattern to pass through are respectively arranged on it. The other end of the return spring 8 is fixedly connected to the extrusion hammer 10, and the extrusion hammer 10 is welded with an extrusion rod 3 with gear pattern that engages with the gear 2 fixed on the rotating steel plate 1;

[0044] The rotating steel plate 1 is fixed to the fixed plate 13 by the fixing anchors 6 or bolts. A rotating steel plate 1 is arranged on each side of the fixed plate 13. The return spring 7 is arranged when the rotating steel plate 1 is fixed. The rotating steel plate 1 is parallel to the fixed plate 13 in the initial state. The return spring 7 has the characteristics of deforming under the action of external force and being able to restore to its original state after the external force is removed. In the safety device, when the built-in plug is pulled out and the squeezing force of the squeezing hammer 10 on the squeezing rod 3 disappears, the restoring force of the return spring 7 will cause the rotating steel plate 1 to change from a vertical state back to a state parallel to the fixed plate 13. This reset function ensures that the safety device can be quickly restored to its initial state after disassembly, which is convenient for the next use and turnover.

[0045] During installation, the return spring 7 should be controlled to make the rotating steel plate 1 parallel to the fixed plate 13. When the extrusion hammer 10 is not subjected to force, the rotating steel plate 1 is parallel to the fixed plate 13. When the extrusion hammer 10 is squeezed by external force, the displacement of the extrusion rod 3 with gear pattern is transmitted to drive the gear 2 to rotate, so that the rotating steel plates 1 on both sides become perpendicular to the fixed plate 13. When the force on the extrusion hammer 10 disappears, the rotating steel plate 1 and the fixed plate 13 continue to remain parallel through the recovery of the return spring 7.

[0046] like Figure 5As shown, the wall-penetrating component is formed by connecting multiple sections of the second hollow steel pipe 14, one end of which is made into an inner lining thread 15, and the other end is made into an outer convex thread 5, which is convenient for connecting the second hollow steel pipes 14 of different modules. Since the thickness of the building wall is mostly 50mm per step, the wall-penetrating component can be made into 50, 100, 200mm and other module lengths by the factory, and after being transported to the site, it can be connected to the required length on site by the thread according to the actual wall thickness on site.

[0047] like Figure 6 As shown, the inner wall fixing component is welded by a third hollow steel tube 21 and a steel plate clamping ring 16. The tail of the third hollow steel tube 21 is made into an inner lining thread 15, and an L-shaped clamping groove 17 is cut at the end portion to fix the built-in plug rod. The steel plate clamping ring 16 is attached to the inside of the wall to fix the inside of the wall.

[0048] like Figure 7 As shown, the built-in insertion rod includes an insertion rod 18 with a diameter smaller than the inner diameter of the hollow steel pipe, and a safety device hanging ring 20 is welded at the end thereof, on which a safety belt can be hung or a steel wire rope can be hung between two devices, so that multiple people can work safely. A nail 19 that can be stuck in the L-shaped groove 17 is also welded thereon. When the built-in insertion rod is inserted into the core of the wall-penetrating rod, the nail 19 can be stuck in the L-shaped groove 17 of the fixing component on the inner side of the wall, so that the built-in insertion rod is fixed in the wall-penetrating rod.

[0049] like Figure 8 As shown in the figure, the device of the present invention is installed and fixed in the reserved hole of the wall. In the embodiment of the present invention, the three major parts of the wall outer fixing part, the wall penetrating part and the wall inner fixing part are assembled by bolt threads (see the attached figure). Figure 5 ), the length of the safety device is controlled by the wall-penetrating component, the safety device is passed through the reserved wall hole or screw hole 22 inside the concrete wall 23, the steel plate clamp ring 16 on the inner side of the wall fixing component is attached to the inside of the wall, the built-in plug rod is inserted into the hollow steel plate of the wall-penetrating safety device, and pressure is applied to the other end of the built-in plug rod. The built-in plug rod squeezes the extrusion hammer 10, and the extrusion hammer 10 is displaced through the connected extrusion rod 3 with gear pattern, driving the gear 2 to rotate, so that the rotating steel plate 1 rotates from a state parallel to the fixed plate 13 to a state perpendicular to it, and is clamped to the outer wall for fixing, so that the safety device is fixed at both ends to achieve the effect of hanging the safety device. In order to ensure that the extrusion hammer 10 is always under pressure during use, the built-in plug rod is rotated to clamp the nail 19 on the built-in plug rod into the L-shaped slot 17 on the component 3 (attached Figure 6). After the construction is completed, rotate the built-in plug rod to disengage the staple 19 from the L-shaped slot 17, and then pull out the built-in plug rod. Under the restoring force of the return spring 7, the rotating steel plate 1 becomes parallel to the fixed plate 13, and the safety device can be quickly pulled out and used in the next scene. During the construction process of the embodiment of the present invention, since all components are modularly constructed, if any component is damaged, it can be quickly replaced on site to improve the overall recovery rate.

[0050] Combination Figure 1-7 ,like Fig. 9 As shown, an embodiment of the present invention provides a method for using a combined edge operation safety device, which specifically includes the following steps:

[0051] S100: Preliminary preparation: According to the architectural design drawings, the safety device components of the required size and specifications are accurately processed according to the modular standards. These components include but are not limited to the wall outside fixing components, wall-penetrating components, wall inside fixing components and built-in plug rods. After processing, all components are quality inspected to ensure that they meet safety standards. After that, these processed components are properly packaged and transported to the construction site to prepare for the subsequent installation work;

[0052] S200: On-site assembly and installation: According to the thickness of the on-site wall, connect the second hollow steel with different moduli into the required length of the through-wall component, and assemble the three major components of the wall outer side fixing component, the through-wall component, and the wall inner side fixing component into an integral device through the bolt thread; pass the assembled safety device through the reserved hole in the wall, ensure that the steel plate clamp ring on the wall inner side fixing component is attached to the inside of the wall, and fixed inside the wall;

[0053] S300: Single-sided installation and fixation: insert the built-in plug rod into the hollow steel tube of the wall-penetrating safety device, apply pressure to the other end of the built-in plug rod, and rotate the built-in plug rod to clamp the pin on the built-in plug rod into the L-shaped card slot of the fixing component on the inner side of the wall. The built-in plug rod squeezes the extrusion hammer, and the extrusion hammer is displaced through the connected extrusion rod with gear pattern, thereby driving the gear to rotate. As the gear rotates, the rotating steel plates on both sides of the fixing plate gradually change from being parallel to the fixing plate to being perpendicular to it, and finally clamped to the outer wall for fixation. This single-sided installation and fixation method not only simplifies the installation process, but also improves installation efficiency;

[0054] S400: Safe hanging and construction work: After ensuring that both ends of the safety device are stable, you can hang a safety belt or wire rope to provide safety protection for construction workers and carry out high-altitude construction work such as exterior wall maintenance and cleaning;

[0055] S500: Disassembly and turnover: After the construction is completed, rotate the built-in rod to disengage the pin from the L-shaped slot, pull out the built-in rod, and under the restoring force of the return spring, the rotating steel plate becomes parallel to the fixed plate. At this time, the safety device can be quickly pulled out and properly stored or turned over to the next construction scene for continued use.

[0056] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
