Description

Technical Field

[0001] This application relates to the field of guardrail technology, and in particular to a modular guardrail for foundation pit protection. Background Technology

[0002] In civil engineering construction, the excavation of foundation pits is essential; however, the edges of these pits pose safety risks such as collapse and falling debris. Currently, commonly used foundation pit protection facilities include fixed guardrails and movable guardrails, which play a crucial role in ensuring construction safety.

[0003] Currently, to address the issue of foundation pit protection, fixed or movable guardrails are typically constructed using methods such as welding and bolting. While these guardrails offer some protection, their fixed structure prevents flexible adjustments based on actual needs, and they present numerous inconveniences during installation, dismantling, and transportation. Utility Model Content

[0004] To address the problem of inconvenient disassembly and assembly of existing foundation pit protection railings, this application provides a modular protection railing for foundation pit protection.

[0005] This application provides a modular guardrail for foundation pit protection, including two support mechanisms and a guardrail assembly installed between the two support mechanisms. The guardrail assembly includes a guardrail frame, and L-shaped rods are fixedly connected to both outer walls of the guardrail frame. Two symmetrically arranged rectangular openings are opened on one outer wall of the guardrail frame. Sliding blocks are slidably connected to the inner walls of the two rectangular openings, and the same mounting frame is fixedly connected to the two sliding blocks. A protective net is fixedly connected to the inner wall of the mounting frame.

[0006] By adopting the above structure, the guardrail of the foundation pit is formed by directly combining two support mechanisms and guardrail components. The four L-shaped bars on the protective frame of the guardrail component facilitate the quick installation of the guardrail. The cooperation between the protective frame and the adjustable mounting frame makes it easy to adjust the overall width of the guardrail.

[0007] Both sliding blocks have threaded grooves on one side of their outer walls, and the inner walls of both threaded grooves are screwed with locking bolts with a T-shaped cross section. Multiple fixing posts are fixedly connected to the inner walls of both sides of the protective frame.

[0008] By adopting the above structure, the sliding block facilitates the sliding of the mounting frame onto the protective frame, the locking bolts facilitate the fixing of the mounting frame onto the protective frame, and the T-shaped locking bolts assist in fixing the mounting frame.

[0009] The support mechanism includes a base, and a column is fixedly connected to the top outer wall of the base.

[0010] By adopting the above structure, the support mechanism can be easily fixed on the ground by setting the base, and the column is installed on the base.

[0011] The column has slots on both outer walls, and four symmetrically arranged adjustment components are slidably installed on the inner walls of the two slots.

[0012] By adopting the above structure, the adjustment components can be easily slidably installed through the slot on the column.

[0013] The adjustment assembly includes an adjustment seat that is slidably connected to the inner wall of the strip-shaped opening, and the cross-section of the adjustment seat is a T-shaped structure.

[0014] By adopting the above structure, and by using a T-shaped adjustment seat, the adjustment seat can be effectively prevented from detaching from the post, thus improving the stability of the guardrail assembly.

[0015] An installation plate is fixedly connected to the top outer wall of the adjustment seat, and a circular opening is provided on the top outer wall of the installation plate, with an L-shaped rod inserted into the inner wall of the circular opening.

[0016] By adopting the above structure, the mounting plate can be easily installed and fixed by the setting of the adjustment seat. When the L-shaped rod is inserted into the circular hole, the guardrail assembly can be quickly installed onto the support mechanism.

[0017] The adjusting seat has an internal mounting cavity, and rectangular openings are provided on both sides of the inner wall of the mounting cavity. T-shaped clamping seats are slidably connected to the inner walls of the two rectangular openings. Two symmetrically arranged fixing brackets are fixedly connected to the inner wall of the mounting cavity, and screws are rotatably connected to the outer wall of one side of the two fixing brackets.

[0018] By adopting the above structure, the mounting cavity in the adjusting seat facilitates the installation of the clamping seat, and the setting of the fixing bracket facilitates the rotational installation of the screw.

[0019] Both of the two clamping seats have threaded grooves on their opposite outer walls. The two screws are screwed onto the inner walls of the two threaded grooves. The same worm gear is fixedly connected between the two screws. The same worm is rotatably connected to the inner walls of both sides of the mounting cavity. The worm and the worm gear mesh with each other, and a rotating part is fixedly connected to one end of the worm.

[0020] By adopting the above structure, the rotating part drives the worm to rotate, the worm to rotate directly drives the worm wheel to rotate, the worm wheel to rotate directly drives the two screws to rotate, and the screws to rotate directly drives the two clamping seats to move towards or away from each other. When the clamping seats move away from each other, they directly press against the inner wall of the strip opening, thus facilitating the fixing of the adjusting seat.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. This application forms a foundation pit protection railing by combining two support structures and guardrail components. Multiple adjustment components are set on the support structure. The setting of adjustment components facilitates the installation of the guardrail components and also facilitates the quick installation of the guardrail components, thus solving the problem of the inconvenience of quick disassembly and assembly of existing foundation pit guardrails.

[0023] 2. This application provides two adjustable clamping seats in the adjustment assembly. The two clamping seats facilitate fixing the adjustment seat in the slot. The cooperation between the two screws, worm gear and worm in the clamping seat facilitates direct drive of the screw to rotate and drive the clamping seat to move. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] Please see Figure 1-3A modular protective fence for foundation pit protection is proposed. Foundation pits pose safety risks such as collapse and falling objects at their edges. To prevent accidents, protective fences are typically used to enclose the pit. Fixed or movable fences are constructed using welding, bolting, or other methods. However, these methods are inconvenient for quick assembly and disassembly, directly impacting on-site installation efficiency. Therefore, a quickly detachable protective fence is proposed, comprising two support mechanisms 1 and a fence assembly 2 installed between the two support mechanisms 1. The fence assembly 2 is mounted on the two support mechanisms 1 to form the fence. The fence assembly 2 includes a protective frame 3. Furthermore, L-shaped rods 4 are fixedly connected to both outer walls of the protective frame 3. The L-shaped rods 4 on the outer wall of the protective frame 3 facilitate direct installation of the protective frame 3. Two symmetrically arranged rectangular openings 7 are opened on one outer wall of the protective frame 3. Sliding blocks 9 are slidably connected to the inner walls of the two rectangular openings 7, and the same mounting frame 6 is fixedly connected to the two sliding blocks 9. When the sliding blocks 9 slide in the rectangular openings 7, it is convenient to directly drive the mounting frame 6 to adjust its position. A protective net 8 is fixedly connected to the inner wall of the mounting frame 6. The protective net 8 is designed to protect the foundation pit and prevent debris from the top of the foundation pit from passing through the mounting frame 6 and falling into the foundation pit.

[0033] In use, the guardrail of the foundation pit is formed by directly combining two support mechanisms 1 and guardrail assembly 2. The four L-shaped rods 4 on the protective frame 3 of the guardrail assembly 2 facilitate the quick installation of the guardrail. The cooperation between the protective frame 3 and the adjustable mounting frame 6 makes it easy to adjust the overall width of the guardrail. When the guardrail assembly 2 is raised, the distance between the protective frame 3 and the ground will increase. The mounting frame 6 can make up for the space between the protective frame 3 and the ground.

[0034] Reference Figure 2-3 Both sliding blocks 9 have threaded grooves on one outer wall, and both threaded grooves have T-shaped locking bolts 10 screwed into their inner walls. When the T-shaped locking bolts 10 are screwed into the sliding blocks 9, it is convenient to directly press and fix the sliding blocks 9 onto the protective frame 3. Both inner walls of the protective frame 3 are fixedly connected with multiple fixing posts 5. The multiple fixing posts 5 are designed to prevent personnel from falling into the pit through the protective frame 3. The sliding blocks 9 are designed to allow the mounting frame 6 to slide onto the protective frame 3. The locking bolts 10 are designed to allow the mounting frame 6 to be fixed onto the protective frame 3. The T-shaped locking bolts 10 are designed to assist in fixing the mounting frame 6.

[0035] Reference Figure 4 The support mechanism 1 includes a base 11, in which a counterweight is provided to increase the stability of the support mechanism 1. At the same time, a round hole is provided on the base 11 to facilitate the passage of fixing bolts. A column 12 is fixedly connected to the top outer wall of the base 11. The setting of the column 12 facilitates the installation of the guardrail. The support mechanism 1 can be easily fixed to the ground by the setting of the base 11, and the column 12 is installed on the base 11.

[0036] Reference Figure 4 The outer walls on both sides of the column 12 are provided with strip-shaped openings 13. The two strip-shaped openings 13 are symmetrically arranged, and four symmetrically arranged adjustment components 14 are slidably installed on the inner walls of the two strip-shaped openings 13. The setting of the strip-shaped openings 13 facilitates the installation of the adjustment components 14. The opening of the strip-shaped openings 13 on the column 12 facilitates the sliding installation of the adjustment components 14. The four adjustment components 14 on the column 12 are symmetrically arranged, which facilitates the assembly of multiple guardrail components 2 through the column 12. In actual operation, the guardrail components 2 and the support mechanism 1 are assembled as needed.

[0037] Reference Figure 5 and Figure 6 The adjustment component 14 includes an adjustment seat 15 that is slidably connected to the inner wall of the strip opening 13. The cross-section of the adjustment seat 15 is a T-shaped structure. The T-shaped structure of the adjustment seat 15 effectively prevents the adjustment seat 15 from detaching from the strip opening 13, thereby ensuring the stable installation of the guardrail component 2. By making the adjustment seat 15 a T-shaped structure, it is possible to effectively prevent the adjustment seat 15 from detaching from the post 12, thus improving the stability of the guardrail component 2.

[0038] Reference Figure 5 An installation plate 17 is fixedly connected to the top outer wall of the adjusting seat 15, and a circular opening 18 is provided on the top outer wall of the installation plate 17. The L-shaped rod 4 is inserted into the inner wall of the circular opening 18. When installing the guardrail, the L-shaped rod 4 can be directly inserted into the circular opening 18 on the installation plate 17, thereby realizing the quick installation of the guardrail. The setting of the adjusting seat 15 facilitates the installation and fixing of the installation plate 17. When the L-shaped rod 4 is inserted into the circular opening 18, the guardrail assembly 2 can be quickly installed onto the support mechanism 1.

[0039] Reference Figure 5 The adjusting seat 15 has an internal mounting cavity 20, and rectangular openings are provided on both inner walls of the mounting cavity 20. T-shaped clamping seats 16 are slidably connected to the inner walls of the two rectangular openings. The mounting cavity 20 facilitates the sliding installation of the two clamping seats 16. When the clamping seats 16 are extended, they directly press against the inner wall of the strip opening 13, thus facilitating the fixing of the adjusting seat 15 to the column 12. Two symmetrically arranged fixing brackets are fixedly connected to the inner wall of the mounting cavity 20, and screws 21 are rotatably connected to one outer wall of each fixing bracket. The two fixing brackets facilitate the rotation of the two screws 21. The mounting cavity 20 in the adjusting seat 15 facilitates the installation of the clamping seats 16, and the fixing brackets facilitate the rotation installation of the screws 21.

[0040] Reference Figure 6Both clamping seats 16 have threaded grooves on their opposite outer walls. Rubber pads are adhered to the sides of both clamping seats 16 near the inner wall of the slot 13. These rubber pads increase the friction between the clamping seats 16 and the inner wall of the slot 13, thus ensuring the stability of the adjusting seat 15. Two screws 21 are screwed onto the inner walls of the two threaded grooves. The clamping seats 16 are screwed onto the outer walls of the screws 21, and driving the screws 21 to rotate directly drives the clamping seats 16. A worm gear 22 is fixedly connected between the two screws 21. The worm gear 22 facilitates direct synchronous rotation of the two screws 21, ensuring synchronous movement of the two clamping seats 16. A worm gear 23 is rotatably connected to the inner walls of both sides of the mounting cavity 20. The worm gear 23 and... The worm gears 22 mesh with each other, and the worm 23 is designed to directly drive the worm gears 22 to rotate. One end of the worm 23 is fixedly connected to a rotating part 19, which has a regular hexagonal cross-section. This allows the rotating part 19 to be rotated using a socket wrench. When the rotating part 19 rotates, it directly drives the worm 23 to rotate, thus facilitating the adjustment of the positions of the two clamping seats 16. The rotation of the rotating part 19 drives the worm 23 to rotate, which in turn drives the worm gears 22 to rotate. When the worm gears 22 rotate, they directly drive the two screws 21 to rotate. When the screws 21 rotate, they directly drive the two clamping seats 16 to move towards or away from each other. When the clamping seats 16 move away from each other, they directly press against the inner wall of the slot 13, thus facilitating the fixing of the adjusting seat 15.

[0041] The implementation principle of this application is as follows: When it is necessary to protect the foundation pit, firstly, the two support mechanisms 1 are installed on the ground through the base 11. Then, the protective frame 3 is inserted into the circular opening 18 on the mounting plate 17 of the adjustment component 14 through four L-shaped rods 4. After the protective frame 3 is installed, the height of the protective frame 3 is adjusted according to the actual situation. When the position of the protective frame 3 is adjusted, the rotating part 19 is rotated. When the rotating part 19 rotates, it directly drives the worm wheel 22 to rotate through the worm 23. When the worm wheel 22 rotates, it directly drives the two screws 21 to rotate. When the screws 21 rotate, they directly drive the pressing seat 16 to slide in the mounting cavity 20. When the two pressing seats 16 extend, they press against the inner wall of the strip opening 13, which makes it convenient to fix the adjusting seat 15 on the column 12, thus making it convenient to adjust the height of the guardrail. When the protective frame 3 rises to the highest position, the two locking bolts 10 are loosened to allow the mounting frame 6 to slide down to the lowest position.

[0042] 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.
