Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a foundation pit engineering support device that can be monitored in real time for safety. Background Technology

[0002] In fields such as building construction and municipal engineering, foundation pit excavation is a key step in foundation construction. Its depth and scope must be strictly determined according to the engineering design. After the foundation pit is excavated, the original mechanical balance of the soil in the pit wall is broken, which can easily lead to serious safety accidents such as collapse and landslide. Therefore, foundation pit support devices have become the core guarantee for maintaining construction safety and ensuring the stability of the pit wall. They are directly related to the life safety of construction workers, the progress of project construction, and the safety of surrounding buildings and facilities. As the scale of engineering construction continues to expand and the depth of foundation pit excavation continues to increase, the geological conditions and the size of foundation pits are becoming increasingly complex and diverse. This places higher demands on the adaptability, safety and monitoring capabilities of support devices. However, existing foundation pit engineering support devices have obvious defects in practical applications, among which the timely warning when the support angle changes and the flexible adjustment of the support structure fulcrum are particularly prominent. On the one hand, most existing support devices lack real-time monitoring and early warning mechanisms for changes in support angle. When the soil on the sidewall of the foundation pit experiences uneven stress or local deformation, the support angle of the support device will change accordingly. If this is not detected in time, it may lead to the overall instability of the support structure. On the other hand, the support structure of existing support devices is mostly fixed, making it difficult to adapt to different geological conditions and changes in the shape of the foundation pit. In actual construction, the geological conditions around the foundation pit are complex and varied, and the bearing capacity of the soil in different areas of the same foundation pit varies. The support structure with fixed support points cannot flexibly adjust the support position and strength according to the actual stress situation, which can easily lead to problems such as excessive local stress or insufficient support, reducing the stability and reliability of the support structure. In summary, existing foundation pit engineering support devices have significant shortcomings in terms of warning of changes in support angle and adjustment of support points, making it difficult to meet the requirements of modern foundation pit engineering for efficient adaptation, real-time early warning, and safety and reliability. Therefore, developing a foundation pit engineering support device that can provide timely warnings when the support angle changes and allows for flexible adjustment of the support points has become an important technical problem that urgently needs to be solved in the field of foundation pit construction. Utility Model Content

[0003] The purpose of this utility model is to provide a foundation pit engineering support device that can be monitored in real time to solve the problems mentioned in the background art, such as the lack of a real-time monitoring and early warning mechanism for changes in support angle, and the fixed support structure support points, which make it difficult to flexibly adjust the support position and force according to the actual stress conditions, resulting in insufficient stability and reliability of the support structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit engineering support device capable of real-time safety monitoring, comprising a support beam, a rotating connecting piece installed on the outer surface of the support beam, and a rotating support plate installed at the lower end of the rotating connecting piece, a groove opened on the outer surface of the support plate, a sliding slider installed inside the groove, and a rotating sliding rod and a sliding cylinder respectively installed at the ends of the two sliders facing outward from the groove, a limit hole opened on the outer surface of the sliding rod, and a pin inserted into the outer surface of the sliding cylinder; A functional plate is fixedly installed on the lower surface of the support beam, and an abutment block is fixedly installed on the outer surface of the functional plate facing the support plate. A rotating extrusion plate and an abutment plate are installed on the outer surface of the upper end of the support plate, and a contact switch is fixedly installed on the outer surface of the extrusion plate facing the abutment plate. An extrusion rod is installed on the upper end of the support plate, and a battery and a warning light are fixedly installed on the outer surface of the upper end of the support plate.

[0005] Preferably, both the slide groove and the slider are T-shaped, and two adjacent slide grooves are V-shaped.

[0006] Using the above technical solution, the T-shaped design of the slide groove and slider can prevent the slider from falling out of the slide groove and ensure the stability of the connection. The two adjacent slide grooves are designed in a figure-eight shape, which makes it easy for the slider to drive the support plate to unfold or retract when sliding in the slide groove, so as to adapt to different support requirements.

[0007] Preferably, one end of the slide rod is located inside the slide cylinder, and the slide rod and the slide cylinder are slidably connected, and the slide cylinder is engaged with the limiting hole by a pin.

[0008] By adopting the above technical solution, the sliding connection between the slide rod and the slide cylinder can adjust the length of the slide rod extending out of the slide cylinder, thereby changing the support range of the support plate. The slide cylinder is connected to the limiting hole by a pin, which can fix the relative position of the slide rod and the slide cylinder and ensure the stability of the opening angle of the support plate.

[0009] Preferably, a spring is connected between the extrusion plate and the contact plate, and the contact plate is positioned directly opposite the contact block.

[0010] Using the above technical solution, the spring between the pressing plate and the contact plate can reset the contact plate when it is not pressed by the contact block, and the contact plate is set directly opposite the contact block to ensure that when the support angle of the support plate changes, the contact block can accurately press the contact plate and trigger the contact switch to realize the early warning.

[0011] Preferably, one end of the extrusion rod penetrates the outer surface of the support plate, and the end of the extrusion rod penetrating the outer surface of the support plate is a hemispherical design.

[0012] With the above technical solution, the end of the extrusion rod that passes through the support plate is designed in a hemispherical shape, which can reduce friction with the outer surface of the extrusion plate, making the extrusion rod rotate more smoothly. The hemispherical design can also transmit the extrusion force evenly, ensuring the adjustment effect on the extrusion plate.

[0013] Preferably, the extrusion rod is threadedly connected to the support plate, and one end of the extrusion rod with a hemispherical design is in contact with the outer surface of the extrusion plate.

[0014] Using the above technical solution, the extrusion rod is threadedly connected to the support plate. By rotating the extrusion rod, its length extending into the support plate can be adjusted, thereby changing the initial position of the extrusion plate and adjusting the trigger sensitivity of the contact switch to adapt to different monitoring needs.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the foundation pit engineering support device that can monitor safety in real time: 1. When the uneven stress on the soil of the foundation pit sidewall causes the support angle of the support plate to change, the relative position of the contact block and the contact plate changes. The contact plate is pressed close to the squeezing plate and triggers the contact switch. The contact switch forms a circuit connection with the battery and the warning light, thereby illuminating the warning light and promptly reminding the construction personnel that the support angle of the support device has changed. This enables real-time safety monitoring and early warning, effectively avoiding the problem of overall instability of the support structure caused by the failure to detect changes in the support angle in time. 2. In actual construction, depending on different geological conditions and the shape of the foundation pit, the opening angle between the two support plates can be changed by rotating the support plates, so that the contact position between the support plates and the ground can be changed to adapt to different support requirements. At the same time, by using the engagement of the pin with different limit holes, the length of the sliding rod extending out of the sliding cylinder can be adjusted, thereby flexibly adjusting the limit of the support plates, ensuring the stability of the opening angle of the support plates during the support process, improving the stability and reliability of the support structure, and adapting to complex and ever-changing construction environments.

The slide cylinder 8 is engaged with the limiting hole 7 through the pin 9. The support beam 1 is connected to the support plate 3 via the rotating connector 2. During construction, the support plate 3 can be rotated according to the shape of the foundation pit to change its contact position with the ground. The two adjacent sliding grooves 4 are designed in a figure-eight shape, so that when the slider 5 slides in the sliding groove 4, it can drive the support plate 3 to open or close. The slider 5 drives the sliding rod 6 and the sliding cylinder 8 to move in the sliding groove 4. The sliding rod 6 can be inserted into the sliding cylinder 8 to slide. According to the actual support requirements, the length of the sliding rod 6 extending out of the sliding cylinder 8 can be adjusted to change the support range of the support plate 3. The limiting hole 7 on the outer surface of the sliding rod 6 engages with the pin 9 on the outer surface of the sliding cylinder 8. When the sliding rod 6 is adjusted to the appropriate position, the pin 9 is inserted, passes through the sliding cylinder 8, and engages with the corresponding limiting hole 7 to fix the relative position of the sliding rod 6 and the sliding cylinder 8, ensuring the stability of the opening angle of the support plate 3.
