Description

Technical Field

[0001] This application relates to the field of construction safety protection technology, and in particular to a retractable edge protection. Background Technology

[0002] Construction site edge protection refers to safety measures implemented during building construction to prevent personnel or objects from falling from unsealed, open areas. In related technologies, construction site edge protection typically consists of steel pipe and coupler-type railings. These railings include uprights, horizontal bars, couplers, toe boards, and safety nets. Workers usually need to assemble the uprights and horizontal bars on-site using couplers before installing and securing the toe boards and safety nets. To reduce the risk of movement, these edge protection measures are typically fixed to the building structure surface using expansion bolts. The inventors believe that the aforementioned construction site edge protection methods suffer from low installation efficiency and inconvenient disassembly / reassembly. Utility Model Content

[0003] To address the issues of low installation efficiency and inconvenient disassembly / reassembly of edge protection at construction sites, this application provides a retractable edge protection system.

[0004] The retractable edge protection provided in this application adopts the following technical solution:

[0005] A retractable edge protection device includes an edge protection body and two fixing devices installed at both ends of the edge protection body. The fixing devices include a first clamping member fixed at one end to the edge protection body, a second clamping member slidably arranged on the first clamping member, and a locking member for locking the first clamping member and the second clamping member to both sides of a wall. The first clamping member includes a fixing part and a first clamping part vertically connected to one end of the fixing part. The other end of the fixing part has an insertion groove along the length direction of the fixing part for sliding arrangement of the second clamping member. The second clamping member includes a movable part inserted into the insertion groove at one end and a second clamping part vertically connected to the other end of the movable part and facing the first clamping part.

[0006] By adopting the above technical solution, when setting up edge protection at the construction site, the operator fixes the two fixing devices located at both ends of the edge protection body to the wall. The first and second clamping parts of the fixing devices can be locked to both sides of the wall by locking parts, which helps to improve the problem of low installation efficiency and inconvenient disassembly of edge protection at the construction site. A plug-in groove is set in the fixing part of the first clamping part, and the movable part of the second clamping part is slidably arranged in the plug-in groove. The distance between the first and second clamping parts can be adjusted by locking parts, which helps to improve the adaptability of the fixing device to different wall thicknesses and the convenience of installation.

[0007] Optionally, the fixing part, the first clamping part, and the second clamping part all have protective rubber pads on their surfaces facing the wall.

[0008] By adopting the above technical solution, the protective rubber pads on the surfaces of the fixing part, the first clamping part, and the second clamping part facing the wall help to reduce damage to the wall surface, while increasing the friction between them and the wall surface, making the first clamping part and the second clamping part clamp more securely.

[0009] Optionally, the locking component includes a first screw fixed at one end to the movable part and a locking nut installed on the first screw. The fixing part has a first through hole at the bottom of the insertion groove for the first screw to pass through, and the edge protection body has a second through hole for the first screw to pass through.

[0010] By adopting the above technical solution, the first screw passes through the first through hole of the fixing part and the second through hole of the edge protection body, and is locked with a locking nut, thus realizing the stable locking of the first clamping part and the second clamping part on both sides of the wall. This helps to improve the problem of inconvenient disassembly and assembly of edge protection on the construction site. At the same time, it makes the edge protection body and the fixing device tightly connected, improving the installation stability of the entire retractable edge protection.

[0011] Optionally, the end of the fixing part is welded to the edge protection body.

[0012] By adopting the above technical solution, the end of the fixing part is welded to the edge protection body, so that the fixing part is firmly connected to the edge protection body, ensuring the installation stability of the first clamping part.

[0013] Optionally, the fixing part has a locking screw hole that penetrates the inner and outer surfaces of the fixing part on the side of the insertion groove away from the protective rubber pad. The locking member includes a second screw threaded into the locking screw hole for locking the movable part and the fixing part, and a bolt head connected to the outer end of the second screw. The movable part has an abutting surface that abuts against the side wall of the insertion groove on the side opposite to the locking member.

[0014] By adopting the above technical solution, the second screw is installed in the locking screw hole of the fixed part using the bolt head, and the end of the second screw abuts against the surface of the movable part. The abutting surface of the movable part abuts against the side wall of the insertion groove, thereby realizing the locking member to lock the movable part and the fixed part, which helps to improve the stability of the fixing device installed on the wall.

[0015] Optionally, the edge protection body includes multiple vertically arranged protective columns and a scissor frame assembly for connecting two adjacent protective columns; two adjacent scissor frame assemblies are hinged together; each scissor frame assembly includes a first connecting rod and a second connecting rod arranged in a cross configuration, and a connecting pin installed at the intersection of the first connecting rod and the second connecting rod; each protective column has a sliding groove along its length for the scissor frame assembly to slide; one end of the first connecting rod is fixed to the end of the sliding groove, and the other end of the first connecting rod is slidably arranged in the sliding groove; one end of the second connecting rod is fixed to the end of the sliding groove, and the other end of the second connecting rod is slidably arranged in the sliding groove.

[0016] By adopting the above technical solution, the specific structure of the edge protection body is disclosed. Multiple protective columns and scissor frame components constitute the edge protection body. The first and second connecting rods of the scissor frame components intersect and are connected by connecting pins. At the same time, the movable ends of both slide in the arrangement grooves of the protective columns. Adjacent scissor frame components are hinged, realizing the telescopic function of the edge protection body. This allows the edge protection body to adapt to different edge size requirements, improving the flexibility and adaptability of the protection structure.

[0017] Optionally, the movable ends of the first connecting rod and the second connecting rod each have a sliding support that is slidably arranged in the arrangement groove; the end of the sliding support has a gear structure, and the protective column is provided with a spur rack on the side wall of the arrangement groove for meshing with the gear structure.

[0018] By adopting the above technical solution, the gear structure at the end of the sliding support meshes with the straight toothed rack on the side wall of the slide groove of the protective column, making the sliding of the movable ends of the first and second links in the slide groove more stable, thus improving the smoothness and reliability of the extension and retraction process of the edge protection body.

[0019] Optionally, the number of scissor bracket assemblies between two adjacent protective columns is two sets, which are respectively slidably arranged on the upper and lower edges of the arrangement groove.

[0020] By adopting the above technical solution, two sets of scissor brackets are installed between adjacent protective columns and slid along the upper and lower edges of the slide grooves, which helps to enhance the stability and expansion coordination of the edge protection body, thereby further improving the protective performance.

[0021] Optionally, the edge protection body further includes a baffle assembly disposed at the lower end of the protective column and connected between adjacent protective columns.

[0022] By adopting the above technical solution, the baffle assembly can form a protective barrier at the lower end of the protective column, which helps to enhance the integrity and safety of edge protection and reduce the risk of objects falling from below.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A retractable edge protection device, comprising an edge protection body and two fixing devices installed at both ends of the edge protection body; when setting up the edge protection device at the construction site, the operator fixes the two fixing devices located at both ends of the edge protection body to the wall respectively, and the first clamping part and the second clamping part of the fixing device can be locked to both sides of the wall by locking parts, which helps to improve the problem of low installation efficiency and inconvenient disassembly of edge protection devices at the construction site;

[0025] 2. By setting protective rubber pads, damage to the wall surface is reduced, while the friction between the pads and the wall surface is increased, making the first and second clamping parts clamp more securely.

[0026] 3. By setting a gear structure that meshes with the spur rack on the side wall of the protective column arrangement groove, the sliding of the moving ends of the first and second connecting rods in the arrangement groove is more stable, which improves the smoothness and reliability of the extension and retraction process of the edge protection body.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a retractable edge protection system.

[0037] Example 1

[0038] Reference Figure 1 The retractable edge protection includes an edge protection body 1 and two fixing devices 2 installed at both ends of the edge protection body 1. The edge protection body 1 includes multiple vertically arranged protective columns 11, scissor frame assemblies 12 for connecting two adjacent protective columns 11, and baffle assemblies 13 arranged at the lower end of the protective columns 11 for connecting adjacent protective columns 11. The protective columns 11 have arrangement grooves 111 along their length for the scissor frame assemblies 12 to slide. The number of scissor frame assemblies 12 between adjacent protective columns 11 is two sets, which are respectively slidably arranged at the upper and lower edges of the arrangement grooves 111.

[0039] Reference Figure 2 and Figure 3 The scissor frame assembly 12 includes a first connecting rod 121 and a second connecting rod 122 arranged in a cross configuration, and a connecting pin 123 installed at the intersection of the first connecting rod 121 and the second connecting rod 122. The fixed ends of the first connecting rod 121 and the second connecting rod 122 are both fixed to the end of the arrangement groove 111 by screws, and the movable ends of the first connecting rod 121 and the second connecting rod 122 each have a sliding support 124 that is slidably arranged in the arrangement groove 111. The ends of two adjacent scissor frame assemblies 12 located on the upper edge of the arrangement groove 111 are hinged together, and the ends of two adjacent scissor frame assemblies 12 located on the lower edge of the arrangement groove 111 are also hinged together.

[0040] Reference Figure 3The sliding support 124 includes a sliding rod 1241 connected to the movable end of the first connecting rod 121 or the second connecting rod 122, and a gear structure 1242 rotatably mounted on the end of the sliding rod 1241. The protective column 11 has a spur rack 112 on the side wall of the arrangement groove 111 for meshing with the gear structure 1242. By utilizing the meshing of the gear structure 1242 at the end of the sliding support 124 with the spur rack 112 on the side wall of the arrangement groove 111 of the protective column 11, the sliding of the movable ends of the first connecting rod 121 and the second connecting rod 122 within the arrangement groove 111 becomes more stable.

[0041] Reference Figure 4 The fixing device 2 includes a first clamping member 21 fixed at one end to the upper end of the protective column 11, a second clamping member 22 slidably arranged on the first clamping member 21, and a locking member 23 for engaging and locking the first clamping member 21 and the second clamping member 22 to both sides of the wall. In this embodiment, both the first clamping member 21 and the second clamping member 22 are L-shaped square tubes.

[0042] Reference Figure 4 and Figure 5 The first clamping member 21 includes a fixing part 211 and a first clamping part 212 perpendicularly connected to one end of the fixing part 211. The other end of the fixing part 211 has an insertion groove 2111 along its length for sliding arrangement of the second clamping member 22. The second clamping member 22 includes a movable part 221 with one end inserted into the insertion groove 2111 and a second clamping part 222 perpendicularly connected to the other end of the movable part 221 and directly opposite the first clamping part 212. The fixing part 211, the first clamping part 212, and the second clamping part 222 all have protective rubber pads 24 on their wall-facing surfaces. The protective rubber pads 24 are multiple strip-shaped rubber pads evenly spaced.

[0043] Reference Figure 5 The locking component 23 includes a first screw 231 fixed at one end to the movable part 221 and a locking nut 232 threaded onto the first screw 231. The bottom of the fixing part 211 and the insertion groove 2111 has a first through hole 2112 for the first screw 231 to pass through. The upper end of the protective post 11 has a second through hole 113 penetrating the inner and outer surfaces for the first screw 231 to pass through.

[0044] The implementation principle of Example 1 is as follows: When setting up edge protection at the construction site, the operator first fixes the fixing device 2 located on one side of the edge guardrail body to the wall, then unfolds the edge guardrail body, and finally fixes the fixing device 2 located on the other side of the edge protection body 1 to another wall, thereby realizing the installation of edge protection on the wall; the first clamping part 21 and the second clamping part 22 of the fixing device 2 can be locked to both sides of the wall by the locking part 23, which helps to improve the problem of low installation efficiency and inconvenient disassembly of edge protection at the construction site; the edge protection body 1 adopts a telescopic structure. By stretching outward the two outermost protective columns 11, the movable end of the scissor frame assembly 12 slides along the arranged slide groove 111, which can realize the unfolding of the edge protection body 1, which helps to improve the installation efficiency of edge protection.

[0045] Example 2

[0046] The retractable edge protection in this application is identical to that in Embodiment 1 except for the locking method of the fixing device 2.

[0047] Reference Figure 6 and Figure 7 The end of the fixing part 211 is welded to the upper end of the edge protection body 1. The fixing part 211 has a locking screw hole 2113 extending through the inner and outer surfaces of the fixing part 211 on the side of the insertion groove 2111 away from the protective rubber pad 24. The locking member 23 includes a second screw 233 threaded into the locking screw hole 2113 for locking the movable part 221 to the locking part, and a bolt head 234 connected to the outer end of the second screw 233. The movable part 221 has an abutting surface 2211 on the side facing away from the locking member 23, which abuts against the side wall of the insertion groove 2111. When the end of the second screw 233 abuts against the movable part 221, the abutting surface 2211 abuts against the side wall of the insertion groove 2111, thereby locking the movable part 221 within the insertion groove 2111 of the fixing part 211.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
