Description

Technical Field

[0001] This application relates to the field of foundation pit support technology, and in particular to a foundation pit support early warning device. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Excavation pit support is a set of measures to support, reinforce and protect the sidewalls and surrounding environment of the excavation pit in order to ensure the safety of underground structure construction and the surrounding environment.

[0003] However, traditional support plates are mostly made of different plates or steel pipes fixed with bolts. When in use, the angle of the pit wall is not fixed, which makes it inconvenient to adjust. At the same time, existing pit support monitoring usually relies on manual periodic inspections and simple measuring instruments. This method has problems such as untimely monitoring and low accuracy, making it difficult to issue early warnings when dangerous situations occur in the pit. This may lead to serious accidents such as pit collapse, causing huge economic losses and casualties. Utility Model Content

[0004] In view of the above problems, this application provides a foundation pit support early warning device to solve the problem that traditional support plates are mostly made of different plates or steel pipes and fixed with bolts. When in use, the angle of the foundation pit wall is not fixed, which makes it inconvenient to adjust. At the same time, existing foundation pit support monitoring usually relies on manual periodic inspections and simple measuring instruments. This method has problems such as untimely monitoring and low accuracy, making it difficult to issue early warnings in time when dangerous situations occur in the foundation pit. This may lead to serious accidents such as foundation pit collapse, causing huge economic losses and casualties.

[0005] This application provides an early warning device for foundation pit support. The early warning device includes a base, a support plate movably connected to one end of the base, an adjustment component at the bottom of the base, and a buzzer fixedly installed on the upper surface of the base. An adjustment mechanism is provided on the back of the support plate, and a linkage mechanism is provided on one side of the buzzer.

[0006] In some embodiments, a fixing plate is fixedly installed on one side surface of the support plate, and a hook is fixedly connected to the surface of the fixing plate. The adjustment assembly includes an adjustment screw rotatably connected inside the base. A positioning cone is fixedly installed at the bottom end of the adjustment screw, and an adjustment handle is fixedly installed at the top end of the adjustment screw.

[0007] In some embodiments, the adjustment mechanism includes a fixed base one fixedly mounted on the upper surface of the base, a threaded rod rotatably connected inside the fixed base one, and a handwheel fixedly mounted at the front end of the threaded rod.

[0008] In some embodiments, a slider is movably mounted on the surface of the threaded rod. The slider is slidably mounted inside the fixed seat. Fixed shafts are fixedly connected to both sides of the slider. A support rod is movably mounted on the surface of the fixed shaft. Fixed blocks are movably connected to both sides of the support rod. The fixed blocks are fixedly mounted on the back of the support plate.

[0009] In some embodiments, the linkage mechanism includes a fixed base two fixedly installed on the upper surface of the base, a slider two slidably installed inside the fixed base two, one side surface of the slider two being fixedly connected to one end of the fixed shaft, and an elastic push rod being fixedly connected to the back side of the slider two.

[0010] In some embodiments, one end of the elastic push rod is fixedly connected to a connecting block, one side surface of the connecting block is fixedly connected to an impact rod, one end of the impact rod is provided with a switch seat, the switch seat is fixedly installed on the inner surface of the fixed seat two, and the switch seat is electrically connected to the buzzer.

[0011] Through the above-described scheme, the angle of the support plate can be easily adjusted by coordinating the handwheel, threaded rod, and slider in the adjustment mechanism. This allows the equipment to adapt to foundation pits of different shapes and working conditions, improving its versatility and applicability, and enhancing the support effect on the foundation pit. The linkage mechanism can sensitively detect changes in the angle of the support plate. When the support plate undergoes a large angle change due to abnormal conditions such as foundation pit deformation, it will drive the slider to slide, ultimately causing the impact rod to strike the switch seat and triggering the buzzer to issue a warning signal. This design can promptly alert relevant personnel to potential dangers in the foundation pit so that appropriate measures can be taken to ensure construction safety.

[0024] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application provides an early warning device for foundation pit support. Figure 1 This is an isometric schematic diagram of the support plate in some embodiments of this application. Figure 2 This is a perspective view of the support plate in some embodiments of this application. For example... Figure 1 , Figure 2 As shown, the foundation pit support early warning device includes a base 1, with a support plate 2 movably connected to one end of the base 1. An adjustment component 3 is provided at the bottom of the base 1, and a buzzer 4 is fixedly installed on the upper surface of the base 1. An adjustment mechanism 5 is provided on the back of the support plate 2. A linkage mechanism 6 is provided on one side of the buzzer 4. A fixing plate 21 is fixedly installed on one side of the support plate 2. A hook 22 is fixedly connected to the surface of the fixing plate 21. The adjustment component 3 includes an adjustment screw 31 rotatably connected inside the base 1. A positioning cone 32 is fixedly installed at the bottom end of the adjustment screw 31, and an adjustment handle 33 is fixedly installed at the top end of the adjustment screw 31.

[0026] In the technical solution of this application embodiment, the base serves as a support platform. By rotating the adjustment handle 33, the adjustment screw 31 is rotated, so that the positioning cone 32 at the bottom is fixed to the ground. The support plate 2 is connected to the base through a hinge, and a fixing plate 21 and a hook 22 are provided on its side to temporarily lock the side wall of the foundation pit and enhance the stability of the support.

[0027] According to other embodiments of this application, such as Figure 3 As shown, the adjustment mechanism 5 includes a fixed seat 51 fixedly installed on the upper surface of the base 1. A threaded rod 52 is rotatably connected inside the fixed seat 51. A handwheel 53 is fixedly installed at the front end of the threaded rod 52. A slider 54 is movably installed on the surface of the threaded rod 52. The slider 54 is slidably installed inside the fixed seat 51. Fixed shafts 55 are fixedly connected to the two sides of the slider 54. A support rod 56 is movably installed on the surface of the fixed shaft 55. Fixed blocks 57 are movably connected to the two sides of the support rod 56. The fixed blocks 57 are fixedly installed on the back of the support plate 2.

[0028] In the technical solution of this embodiment, by rotating the handwheel 53, the threaded rod 52 is rotated, which drives the slider 54 to slide up and down in the fixed seat 51, so that the slider 54 moves horizontally. The support rod 56 pushes and pulls the support plate 2 to adjust the tilt angle, ensuring that it fits tightly with the pit wall.

[0029] According to other embodiments of this application, such as Figure 4 As shown, the linkage mechanism 6 includes a fixed base 61 fixedly installed on the upper surface of the base 1. A slider 62 is slidably installed inside the fixed base 61. One side surface of the slider 62 is fixedly connected to one end of the fixed shaft 55. An elastic push rod 63 is fixedly connected to the back of the slider 62. One end of the elastic push rod 63 is fixedly connected to a connecting block 64. One side surface of the connecting block 64 is fixedly connected to an impact rod 65. One end of the impact rod 65 is provided with a switch seat 66. The switch seat 66 is fixedly installed on the inner surface of the fixed base 61 and is electrically connected to the buzzer 4.

[0030] In the technical solution of this embodiment, when the deformation of the pit sidewall causes the support plate 2 to shift, the support rod 56 drives the fixed shaft 55 to move, pushes the slider 62 to slide, the elastic push rod 63 drives the impact rod 65 to trigger the switch seat 66, and the buzzer 4 immediately sounds an alarm.
