Description

Technical Field

[0001] This utility model relates to the field of foundation pit construction technology, specifically to a foundation pit construction safety protection device. Background Technology

[0002] In the construction process, foundation pits are a common part of basic engineering. Due to the significant safety risks around foundation pits, such as accidental falls by personnel or objects falling into the pit, effective safety protection devices are required. However, some existing protective devices have poor stability and are difficult to meet the diverse safety protection needs of modern construction.

[0003] A search revealed a mobile foundation pit protection device with authorization announcement number CN220336619U, which includes a fixed base with its bottom wall in contact with the ground; a protective net installed above the fixed base; a fixing component for connecting the protective net and the fixed base; and a connecting mechanism installed on the fixed base for connecting adjacent fixed bases.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: Although the existing foundation pit protection device can improve the stability of the protection device, the two adjacent protection devices are connected by direct fixing, which is inconvenient to disassemble and assemble, affecting construction efficiency, and is not conducive to flexibly adjusting the protection range according to the foundation pit construction progress. Therefore, it is urgent to design a foundation pit construction safety protection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a safety protection device for foundation pit construction in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The foundation pit construction safety protection device includes multiple interconnected protection units. Each protection unit includes a frame, and a reinforcement component is provided at the middle of one side of the frame. Wire mesh is installed on the frame, and a disassembly and assembly component for fixing the wire mesh is also provided on the frame. A connecting seat is fixed to the top of one end of the frame, and the cross-section of the connecting seat is designed to be cross-shaped. A connecting frame is fixed to the other end of the frame, and connecting grooves are opened on the top of all four sides of the connecting frame. The inner walls of the connecting grooves and the inner walls of the connecting frame are adapted to the outer walls of the connecting seat. A positioning component is provided at the bottom of the connecting frame.

[0008] Furthermore, the reinforcement component includes a fixed frame that is fixedly installed in the middle of one side of the frame, and movable grooves are provided on both sides of the bottom of the fixed frame. A lifting plate is inserted into the inner wall of the movable groove. First ground plugs are fixedly installed at both ends of the bottom of the lifting plate. A threaded rod is rotatably connected to the middle of the fixed frame, and a threaded hole that matches the outer wall of the threaded rod is provided in the middle of the lifting plate. A knob is fixed to the top of the threaded rod.

[0009] Furthermore, a support plate is fixedly installed on one side of the bottom of the frame, and a first through hole is provided on the support plate for the first grounding plug to pass through.

[0010] Furthermore, the disassembly and assembly assembly includes a slot formed on one side of the inner wall of the frame, and a wire mesh is placed in the slot. A square card holder is attached to the inner wall of the slot, and mounting plates are fixed to the top and bottom inner walls of the square card holder. The mounting plates are fixedly connected to one side of the fixed frame by screws.

[0011] Furthermore, both one side of the square card holder and one side of the slot are provided with equally spaced, crisscrossing card slots, and the wire mesh is attached to the card slots.

[0012] Furthermore, the positioning component includes a movable frame movably disposed within the connecting frame, and a fixed seat passing through the interior of the movable frame is fixed to the inner wall of the connecting frame. A spring is fixedly installed on the top of the fixed seat and the top inner wall of the movable frame. A second grounding plug is fixedly installed on the bottom of the movable frame, and a second through hole is opened at the bottom of the connecting frame for the second grounding plug to pass through.

[0013] Furthermore, a reflective strip is provided on the other side of the fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, adjacent protective units are spliced ​​together by a "cross-shaped connecting seat and a connecting frame with a connecting groove". The connecting seat is compatible with the inner wall of the connecting frame and the connecting groove, enabling quick assembly and disassembly. Compared with the traditional direct fixing connection method, this greatly simplifies the splicing and disassembly process and improves construction efficiency. At the same time, this splicing structure makes it easy to flexibly adjust the protection range according to the progress of the foundation pit construction. Protective units can be added or reduced at any time to meet the protection needs of different stages, enhancing the practicality and adaptability of the device.

[0016] In this invention, when two adjacent protective units are joined together in the positioning component, the connecting seat presses down the movable frame and the second grounding plug, causing the second grounding plug to penetrate deep into the ground, thus enhancing the stability of the connection between adjacent protective units. In the reinforcement component, the lifting plate and the first grounding plug are raised and lowered by rotating the threaded rod, causing the first grounding plug to penetrate deep into the ground. Combined with the supporting effect of the support plate, the stability of a single protective unit is effectively improved, thereby ensuring that the overall protective structure is more stable in the construction environment and reducing the risk of tipping over.

[0017] In this invention, the assembly and disassembly components fix the wire mesh through the cooperation of slots, square brackets and slots, and the square brackets are connected to the fixing frame screws through the mounting plate, which makes the installation, disassembly and replacement of the wire mesh simple and quick. When the wire mesh is damaged, there is no need to replace the entire protective device, only to repair or replace the wire mesh, which reduces maintenance costs and workload.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 In this embodiment of the utility model, the safety protection device for foundation pit construction includes multiple interconnected protection units 1. Each protection unit 1 includes a frame 2, and a reinforcing component 4 is provided at the middle position of one side of the frame 2. The reinforcing component 4 includes a fixed frame 41 fixedly installed at the middle position of one side of the frame 2, and movable grooves 42 are opened at the bottom of both sides of the fixed frame 41. A lifting plate 45 is inserted into the inner wall of the movable groove 42. First ground plugs 46 are fixedly installed at both ends of the bottom of the lifting plate 45. A threaded rod 44 is rotatably connected to the middle position of the fixed frame 41, and a threaded hole adapted to the outer wall of the threaded rod 44 is opened at the middle position of the lifting plate 45. A knob 43 is fixed at the top of the threaded rod 44. By rotating the threaded rod 44, the lifting plate 45 and the first ground plug 46 are raised and lowered, so that the first ground plug 46 penetrates into the ground, effectively... The stability of a single protective unit 1 is improved. A wire mesh 3 is installed on the frame 2, and a disassembly and assembly component for fixing the wire mesh 3 is also provided on the frame 2. A connecting seat 5 is fixed to the top of one end of the frame 2, and the cross section of the connecting seat 5 is designed to be cross-shaped. A connecting frame 9 is fixed to the other end of the frame 2, and a connecting groove 11 is opened on the top of all four sides of the connecting frame 9. The inner wall of the connecting groove 11 and the inner wall of the connecting frame 9 are adapted to the outer wall of the connecting seat 5. A positioning component is provided at the bottom of the connecting frame 9. Two adjacent protective units 1 are spliced ​​together through the connecting seat 5, the connecting frame 9 and the connecting groove 11, which can achieve the effect of quick disassembly and assembly. At the same time, it is convenient to flexibly adjust the protection range according to the construction progress of the foundation pit, and the protective units 1 can be added or removed at any time to meet the protection needs of different stages, thereby enhancing the practicality and adaptability of the device.

[0027] Specifically, a support plate 7 is fixedly installed on one side bottom of the frame 2, and a first through hole 47 is provided on the support plate 7 for the first grounding plug 46 to pass through, thereby further increasing the stability of the entire protective device.

[0028] Specifically, the assembly and disassembly components include slots 17 on one side of the inner wall of the frame 2, with wire mesh 3 placed inside the slots 17. A square bracket 6 is attached to the inner wall of the slots 17, and mounting plates 16 are fixed to the top and bottom inner walls of the square bracket 6. The mounting plates 16 are fixedly connected to one side of the fixed frame 41 by screws. Both one side of the square bracket 6 and one side of the slots 17 have equally spaced, crisscrossing slots 18, and the wire mesh 3 is snapped into the slots 18. The wire mesh 3 is fixed by the cooperation of the slots 17, the square bracket 6, and the slots 18 in the assembly and disassembly components. The square bracket 6 is connected to the fixed frame 41 by screws through the mounting plate 16, making the installation, disassembly, and replacement of the wire mesh 3 simple and quick.

[0029] Specifically, the positioning component includes a movable frame 10 movably disposed within the connecting frame 9, and a fixed seat 13 passing through the interior of the movable frame 10 is fixed to the inner wall of the connecting frame 9. A spring 12 is fixedly installed on the top of the fixed seat 13 and the top inner wall of the movable frame 10. A second grounding plug 14 is fixedly installed on the bottom of the movable frame 10, and a second through hole 15 is opened at the bottom of the connecting frame 9 for the second grounding plug 14 to pass through. When two adjacent protective units 1 are spliced, the connecting seat 5 presses the movable frame 10 and the second grounding plug 14 downward, so that the second grounding plug 14 penetrates into the ground, thereby enhancing the stability of the connection part of the adjacent protective units 1.

[0030] Specifically, a reflective strip 8 is provided on the other side of the fixed frame 41 to serve as a safety warning by reflecting light.

[0031] The working principle of this utility model is as follows: multiple protective units 1 are spliced ​​together with the connecting frame 9 through the connecting seat 5 to form an overall protective structure. When splicing, the connecting seat 5 of one protective unit 1 is inserted into the connecting frame 9 of another. The connecting seat 5 is adapted to the inner wall of the connecting frame 9 and the connecting groove 11 to achieve initial positioning. At the same time, the second ground plug 14 at the bottom of the movable frame 10 in the positioning component is inserted into the ground through the second through hole 15 under the pressure of gravity of the connecting seat 5, which strengthens the stability of the connection part.

[0032] In a single protective unit 1, the frame 2 is the main structure, and the wire mesh 3 is fixed by a disassembly and assembly assembly. That is, the wire mesh 3 is placed in the slot 17 of the frame 2, the square card holder 6 fits against the inner wall of the slot 17, and the mounting plates 16 at the top and bottom are connected to the fixing frame 41 by screws. The wire mesh 3 is fixed by being snapped into the card slot 18, which facilitates disassembly and replacement.

[0033] Next, the overall stability is improved by reinforcing component 4, that is, rotating knob 43 drives threaded rod 44 to rotate, causing lifting plate 45 to rise and fall along movable groove 42, and first ground plug 46 passes through first through hole 47 of support plate 7 and is inserted into the ground to enhance the connection between the device and the ground.

[0034] Finally, the reflective strip 8 on the other side of the fixed frame 41 serves as a safety warning by reflecting light.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
