Description

Technical Field

[0001] This invention relates to the field of safety railing technology, specifically a device for quickly installing and removing safety railings for hoisting openings. Background Technology

[0002] Safety railings are standardized safety protection facilities specifically designed for hoisting openings in building construction, and can be quickly installed and dismantled.

[0003] Chinese patent CN222822907U discloses a protective safety railing for construction projects, comprising several railing bodies. Each railing body has a connector, which includes several mounting blocks, inserts, and hinges. Several hinges are respectively installed on both sides of the railing body, several mounting blocks are located on one side of the railing body, and several inserts are located on the other side of the railing body. The mounting blocks and inserts are fixedly connected to their respective adjacent hinges. The mounting blocks engage with inserts on another railing body. This patent allows for the quick assembly or disassembly of two railing bodies without the need for tools, facilitating the modification of the protective safety railing's shape according to actual needs.

[0004] However, the above-mentioned patent has the following shortcomings: In order to ensure safety, when no hoisting operation is being carried out, the edges of these openings are usually protected by fixed welded railings; the fixed welded railings need to be destructively removed by cutting tools during hoisting operations, and then re-welded and installed after the operation. This method is time-consuming, labor-intensive, costly, and has poor reusability.

[0005] Therefore, the present invention provides a device for quick installation and removal of safety railings for hoisting openings. Summary of the Invention

[0006] The purpose of this invention is to provide a quick-installation and dismantling safety railing device for hoisting openings, in order to solve the problems mentioned in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a quick-installation and dismantling safety railing device for hoisting openings, including a ground, on which the opening wall is fixedly installed, and also including a pre-embedded installation mechanism, a railing mechanism and a connecting mechanism;

[0008] Multiple sets of pre-embedded installation mechanisms are provided on the ground. Each pre-embedded installation mechanism includes a snap-fit ​​component provided on the ground and an elastic support component provided on the snap-fit ​​component.

[0009] The railing mechanism is mounted on the snap-fit ​​assembly. The railing mechanism includes a guardrail assembly mounted on the snap-fit ​​assembly. The guardrail assembly is provided with an adjustment assembly and multiple sets of moving assemblies.

[0010] Each set of guardrail components is provided with multiple sets of connection mechanisms.

[0011] Furthermore, the snap-fit ​​assembly includes two pre-embedded stainless steel pipes fixedly installed on the ground. Two connecting brackets are symmetrically fixedly installed on each pre-embedded stainless steel pipe. A side shell is fixedly installed on each connecting bracket. Two first springs are connected to the inner wall of the side shell. The ends of the two first springs are connected to a telescopic block that is slidably connected to the side shell. A snap-fit ​​sleeve is fixedly installed on the telescopic block.

[0012] Furthermore, the elastic support assembly includes two symmetrically fixed sleeves mounted on a pre-embedded stainless steel pipe. Each fixed sleeve has a second spring connected to its inner wall, and the end of the second spring is connected to a telescopic rod that is slidably connected to the fixed sleeve.

[0013] Furthermore, a limiting ring shell is fixedly installed on the telescopic rod, and a threaded sleeve is rotatably installed between the two limiting ring shells.

[0014] Furthermore, each of the telescopic blocks is fixedly installed with a threaded plate that is threadedly connected to the threaded sleeve.

[0015] Furthermore, the guardrail assembly includes two stainless steel tube sleeves that are rotatably mounted on two sets of snap-fit ​​sleeves, and an adjustable guardrail is slidably mounted between the two stainless steel tube sleeves.

[0016] Furthermore, the adjustment assembly includes two sets of positioning holes opened on the adjustment railing, and each of the stainless steel tube sleeves is threaded with a positioning bolt that matches the positioning hole.

[0017] Furthermore, the movable component includes two housings that are slidably mounted on two stainless steel tube sleeves, and a connecting rod is fixedly mounted between the two housings.

[0018] Furthermore, each of the housings has two sliding sleeves symmetrically slidably installed, and a clamping piece adapted to the stainless steel tube sleeve and the adjusting rail is fixedly installed between the two sliding sleeves. A compression bolt that is rotatably connected to the clamping piece is threaded onto the housing.

[0019] Furthermore, the connecting mechanism includes two symmetrically slidingly mounted connecting pieces between two stainless steel sleeves, and fastening screws and nuts are slidably mounted on both connecting pieces.

[0020] The beneficial effects of this invention are:

[0021] (1) This invention moves the stainless steel pipe sleeve between two snap-fit ​​sleeves, and moves the two snap-fit ​​sleeves to snap into the stainless steel pipe sleeve. The snap-fit ​​sleeve can drive the telescopic block to pull the first spring. By moving upward, the threaded sleeve is screwed. The threaded sleeve pulls the second spring through the limiting ring shell and the telescopic rod, so that the threaded sleeve is fixed on the threaded plate by the thread action, so as to complete the installation of the stainless steel pipe sleeve. The adjacent stainless steel pipe sleeves are fixed by the connecting plate and the fastening screw nut. By screwing the threaded sleeve out of the outside of the threaded plate, the second spring can use its own elastic force to drive the threaded sleeve to move downward through the telescopic rod and the limiting ring shell, so that the first spring can use its own elastic force to drive the snap-fit ​​sleeve to reset through the telescopic block, so as to facilitate the disassembly of the stainless steel pipe sleeve. Then the connecting plate and the fastening screw nut are disassembled. When no hoisting operation is performed, it can be used as a protective railing for the edge opening. When hoisting operation is performed, it can be easily disassembled and quickly restored after hoisting is completed.

[0022] (2) In this invention, a suitable number of connecting rods are installed between two stainless steel pipe sleeves by using a casing. Then, an adjusting rail is inserted between the two stainless steel pipe sleeves. By moving the adjusting rail upward, the adjusting rail can be moved to a suitable height along the stainless steel pipe sleeve. The positioning bolt is screwed into the positioning hole at the appropriate position to fix the adjusting rail. The casing is moved to a suitable position by moving the connecting rod. By turning the compression bolt, the compression bolt drives the clamping plate to move under the action of the casing thread. The clamping plate drives the sliding sleeve to move along the casing, so that the clamping plate can cooperate with the casing to clamp the stainless steel pipe sleeve or the adjusting rail and fix the connecting rod. Thus, the height of the device can be adjusted according to the opening, thereby improving the protective effect. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1-8 As shown, the present invention discloses a quick-installation and dismantling safety railing device for hoisting openings, comprising a ground 1, on which an opening wall 2 is fixedly installed, and further comprising a pre-embedded installation mechanism, a railing mechanism, and a connecting mechanism. Multiple sets of pre-embedded installation mechanisms are provided on the ground 1. Each pre-embedded installation mechanism includes a snap-fit ​​component disposed on the ground 1, and an elastic support component is disposed on the snap-fit ​​component. Multiple sets of connecting mechanisms are provided between each set of railing components. The snap-fit ​​component includes two pre-embedded stainless steel pipes 3 fixedly installed on the ground 1. Two connecting frames 6 are symmetrically fixedly installed on each pre-embedded stainless steel pipe 3. A side shell 7 is fixedly installed on each connecting frame 6. Two first springs 8 are connected to the inner wall of the side shell 7, and the ends of the two first springs 8 are connected together. There is a telescopic block 9 that is slidably connected to the side shell 7. A snap-fit ​​sleeve 10 is fixedly installed on the telescopic block 9. The elastic support assembly includes two fixed sleeves 11 that are symmetrically fixedly installed on the pre-embedded stainless steel pipe 3. A second spring 12 is connected to the inner wall of each fixed sleeve 11. The end of the second spring 12 is connected to a telescopic rod 13 that is slidably connected to the fixed sleeve 11. A limit ring shell 14 is fixedly installed on the telescopic rod 13. A threaded sleeve 15 is rotatably installed between the two limit ring shells 14. A threaded piece 16 that is threadedly connected to the threaded sleeve 15 is fixedly installed on each telescopic block 9. The connecting mechanism includes two connecting pieces 24 that are symmetrically slidably installed between the two stainless steel pipe sleeves 4. A fastening screw nut 25 is slidably installed on the two connecting pieces 24.

[0035] Specifically, by moving the stainless steel pipe sleeve 4 between the two snap-fit ​​sleeves 10, the two snap-fit ​​sleeves 10 are moved to snap into the stainless steel pipe sleeve 4. The snap-fit ​​sleeves 10 can drive the telescopic block 9 to pull the first spring 8. By moving upward, the threaded sleeve 15 is screwed. The threaded sleeve 15 pulls the second spring 12 through the limiting ring shell 14 and the telescopic rod 13, so that the threaded sleeve 15 is fixed on the threaded plate 16 by the thread action, thus completing the installation of the stainless steel pipe sleeve 4. The first spring 8 and the second spring 12 can prevent the installation of the device from becoming loose. The adjacent connecting plate 24 and the fastening screw nut 25 are used to secure the device. The stainless steel pipe sleeve 4 is fixed; by unscrewing the threaded sleeve 15 out of the threaded plate 16, the second spring 12 can use its own elastic force to drive the threaded sleeve 15 downward through the telescopic rod 13 and the limiting ring shell 14, so that the first spring 8 can use its own elastic force to drive the snap-fit ​​sleeve 10 to reset through the telescopic block 9, so as to facilitate the disassembly of the stainless steel pipe sleeve 4. Then the connecting plate 24 and the fastening screw nut 25 are disassembled. When no hoisting operation is performed, it can be used as a protective railing for the edge opening. When hoisting operation is performed, it can be easily disassembled and quickly restored after hoisting is completed.

[0036] In this embodiment, the railing mechanism is mounted on the snap-fit ​​assembly. The railing mechanism includes a guardrail assembly mounted on the snap-fit ​​assembly, an adjustment assembly mounted on the guardrail assembly, and multiple sets of moving assemblies mounted on the guardrail assembly. The guardrail assembly includes two stainless steel tube sleeves 4 that are rotatably mounted on two sets of snap-fit ​​sleeves 10 respectively. An adjustment railing 5 is slidably mounted between the two stainless steel tube sleeves 4. The adjustment assembly includes two sets of positioning holes 17 opened on the adjustment railing 5. Each stainless steel tube sleeve 4 is threaded with a positioning bolt 18 that is adapted to the positioning hole 17. The moving assemblies include two housings 19 that are slidably mounted on the two stainless steel tube sleeves 4 respectively. A connecting rod 20 is fixedly mounted between the two housings 19. Two sliding sleeves 21 are symmetrically slidably mounted on each housing 19. A clamping piece 22 adapted to the stainless steel tube sleeve 4 and the adjustment railing 5 is fixedly mounted between the two sliding sleeves 21. A compression bolt 23 that is rotatably connected to the clamping piece 22 is threadedly mounted on the housing 19.

[0037] Specifically, a suitable number of connecting rods 20 are installed between two stainless steel pipe sleeves 4 using the housing 19. Then, the adjusting rail 5 is inserted between the two stainless steel pipe sleeves 4. By moving the adjusting rail 5 upward, it can be moved to a suitable height along the stainless steel pipe sleeve 4. The positioning bolt 18 is screwed into the positioning hole 17 in the appropriate position to fix the adjusting rail 5. The housing 19 is moved to a suitable position by moving the connecting rods 20. By turning the clamping bolt 23, the clamping bolt 23 drives the clamping plate 22 to move under the action of the thread of the housing 19. The clamping plate 22 drives the sliding sleeve 21 to move along the housing 19, so that the clamping plate 22 can cooperate with the housing 19 to clamp the stainless steel pipe sleeve 4 or the adjusting rail 5, and fix the connecting rod 20. Thus, the height of the device can be adjusted according to the opening, improving the protective effect.

[0038] Working principle: During the main structure construction phase, pre-embedded stainless steel pipes 3 are installed in advance. The stainless steel pipe sleeve 4 is moved between two snap-fit ​​sleeves 10, and the two snap-fit ​​sleeves 10 are moved to snap into the stainless steel pipe sleeve 4. The snap-fit ​​sleeves 10 can drive the telescopic block 9 to pull the first spring 8. By moving upwards, the threaded sleeve 15 is screwed. The threaded sleeve 15, through the limiting ring shell 14 and the telescopic rod 13, pulls the second spring 12, so that the threaded sleeve 15 is fixed to the threaded plate 16 by the thread action, thus completing the installation of the stainless steel pipe sleeve 4. A suitable number of connecting rods 20 are installed between the two stainless steel pipe sleeves 4 through the sleeve shell 19. Finally, the adjusting railing 5 is inserted between the two stainless steel pipe sleeves 4. In between, by moving the adjusting railing 5 upward, the adjusting railing 5 can be moved upward along the stainless steel tube sleeve 4 to a suitable height. The positioning bolt 18 is screwed into the positioning hole 17 in the appropriate position to fix the adjusting railing 5. The sleeve 19 is moved to a suitable position by moving the connecting rod 20. By turning the clamping bolt 23, the clamping bolt 23 drives the clamping plate 22 to move under the action of the thread of the sleeve 19. The clamping plate 22 drives the sliding sleeve 21 to move along the sleeve 19, so that the clamping plate 22 can cooperate with the sleeve 19 to clamp the stainless steel tube sleeve 4 or the adjusting railing 5, and fix the connecting rod 20. The adjacent stainless steel tube sleeve 4 is fixed by the connecting piece 24 and the fastening screw nut 25.
