Description

Technical Field

[0001] This utility model relates to the field of support testing technology, specifically a support stress testing device. Background Technology

[0002] As core auxiliary equipment in fields such as building construction, power maintenance, and municipal maintenance, scaffolding needs to bear the weight of workers and tools for extended periods. Its stress stability and structural safety are directly related to the safety of workers. Before being put into use and during regular maintenance, the load-bearing capacity of scaffolding must be verified through stress testing to prevent breakage due to excessive stress caused by material fatigue, welding defects, corrosion, etc., which could lead to falls.

[0003] In traditional methods of stress detection for support structures, the pressure sensors are mostly surface-mounted. These sensors are prone to poor contact, interrupted or distorted data acquisition, and loss of accuracy due to support structure slippage. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a support force detection device to solve the problem mentioned in the background art that the support is prone to poor contact with the attached pressure sensor due to slippage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support force detection device, comprising a double ladder support and a detection component, wherein positioning components are sleeved on the bottom of both sides of the double ladder support; The positioning component includes two base plates respectively located at the bottom of both sides of the double ladder support, and two front-to-back limiting frames are installed on the top surface of the base plates. The detection assembly includes a pressure sensor installed within the positioning assembly, a hydraulic jack for applying pressure to the double ladder support, a miniature camera located on one side of the double ladder support, and a display electrically connected to the miniature camera, the hydraulic jack, and the pressure sensor.

[0006] Preferably, the limiting frames are arranged in an "[" shape, and the openings of the limiting frames on the two base plates are arranged opposite to each other.

[0007] Preferably, slope plates are installed on opposite sides of both base plates, and the slope plates have a triangular cross-section.

[0008] Preferably, the inner wall of the limiting frame is provided with a groove, the surface of the limiting frame is fitted with a threaded sleeve, and an adjusting rod is inserted into the two threaded sleeves arranged at the front and rear. A pressing structure is provided along the groove inside the limiting frame, and the pressing structure extends outward and is rotatably fitted onto the surface of the adjusting rod.

[0009] Preferably, the pressing structure includes an extension plate rotatably sleeved on the surface of the adjusting rod, a pressing plate is provided inside the groove, and a solid column is installed at the end of the extension plate. The solid column extends into the groove along the surface of the limiting frame and is fixed to the pressing plate.

[0010] Preferably, a limiting block is integrally connected to the end of the pressure plate, the thickness of the limiting block is the same as the depth of the groove, and the thickness of the pressure plate is half the depth of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model embeds the pressure sensor into the base plate, forming an integral part with the base plate. Then, a limiting frame is used to cover the bottom of the double ladder support frame. This can prevent the double ladder support frame from detaching from the base plate when it is subjected to force and its opening angle increases, thereby ensuring uninterrupted data acquisition.

[0012] 2. This utility model uses a pressure sensor to collect the force data of the double ladder support 1 in real time, and uses a miniature camera to capture the dynamics of the double ladder support. All data and images are transmitted to the display at the same time. The staff can observe the force changes and structural stability of the double ladder support 1 at the same time or later through the display, which is faster and more accurate than visual observation.

[0013] 3. By rotating the adjusting rod in the set direction, the pressure-retaining structure is driven to apply pressure and limit the bottom side of the double ladder support, which can fix ladders of different widths and ensure stability during force testing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figures 1-4 This utility model proposes a support structure stress testing device, which aims to detect the load-bearing capacity and stress stability of the support structure, and avoid safety accidents caused by excessive stress or structural defects in the support structure. This support structure stress testing device includes three parts: a double-ladder support 1, a positioning component 2, and a testing component 3. The double-ladder support 1 is the target support to be tested. During testing, its bottom sides need to be engaged with the positioning component 2 to ensure that the double-ladder support 1 is fixed in position and stable under stress during the testing process. The positioning component 2 is used to fix the bottom position of the double-ladder support 1, providing a stable stress testing benchmark for the testing component 3. The basic structure of the positioning component 2 includes two base plates 201 and two front-to-back limiting frames 202 fixedly installed on the top surface of each base plate 201. The two base plates 201 correspond to the bottom sides of the double ladder support 1 respectively. The limiting frame 202 is arranged in a [ shape, and the inner wall of the limiting frame 202 is adapted to the side wall of the ladder frame at the bottom of the double ladder support 1. It can be fitted on the bottom of the ladder frame and limit its movement. This can effectively prevent the double ladder support 1 from sliding to both sides due to force during the actual testing stage, which would cause the opening angle to increase and lead to the separation from the testing component 3.

[0018] The detection component 3 is the core component for force detection, including a pressure sensor 301, a hydraulic jack 302, a miniature camera 303, and a display 304. The pressure sensor 301 can be optionally embedded in the base plate 201 of the positioning component 2, with its sensing surface in contact with the bottom of the double ladder support 1, for real-time acquisition of the pressure value transmitted from the double ladder support 1 to the base plate 201; the hydraulic jack 302 can be optionally fixedly installed on the ground or auxiliary support on one side of the double ladder support 1, with its output end facing the ladder frame body of the double ladder support 1, for applying a set amount of pressure to the double ladder support 1 to simulate the load-bearing capacity of the double ladder support 1 in actual use; the miniature camera 303 can be optionally fixed to one side of the double ladder support 1 through an auxiliary support, with its lens facing the overall structure of the double ladder support 1, for capturing dynamic changes of the double ladder support 1 during the detection process, such as ladder frame deformation and displacement at the connection points; the display 304 is electrically connected to the pressure sensor 301, the hydraulic jack 302, and the miniature camera 303 through wires or a wireless module, and can display the pressure data collected by the pressure sensor 301 and the output pressure parameters of the hydraulic jack 302 in real time, while receiving and playing the images captured by the miniature camera 303, and must also have data storage function for subsequent analysis of the detection results.

[0019] Following the above, during the actual testing of the double ladder support 1, the bottom sides of the double ladder support 1 are fitted into the limiting frame 202 of the positioning component 2 and stabilized with other structures of the positioning component 2. After that, the hydraulic jack 302 is activated to apply pressure to the double ladder support 1. The pressure sensor 301 collects the force data of the double ladder support 1 in real time and captures the dynamics of the double ladder support 1 with the miniature camera 303. All data and images are transmitted synchronously to the display 304. The staff can observe the force changes and structural stability of the double ladder support 1 synchronously or later through the display 304 to determine whether it meets the standard.

[0020] By embedding the pressure sensor 301 within the positioning component 2, problems such as poor sensor contact, data acquisition terminal issues, or distortion caused by the sliding of the double ladder bracket 1 can be effectively avoided. This ensures that the pressure sensor 301 is stably attached to the bottom of the double ladder bracket 1, enabling reliable real-time force data acquisition.

[0021] To effectively improve the stability of the bottom of the double ladder support 1 fitting within the limiting frame 202, such as... Figures 1-3 As shown, a groove 2021 is provided on the inner wall of each limiting frame 202, and a threaded sleeve 2022 is installed on the surface of the limiting frame 202, with the axes of the two threaded sleeves 2022 being collinear; an adjusting rod 204 is inserted into the two threaded sleeves 2022 arranged in the front and rear, and the surface of the adjusting rod 204 is provided with external threads that are adapted to the internal threads of the threaded sleeve 2022. By rotating the adjusting rod 204, its axial movement along the threaded sleeve 2022 can be controlled. A pressing structure 205 is provided along the groove 2021 inside the limiting frame 202. The pressing structure 205 extends outward and is rotatably sleeved on the surface of the adjusting rod 204. The pressing structure 205 includes an extension plate 2051 rotatably sleeved on the surface of the adjusting rod 204. A pressing plate 2052 is provided inside the groove 2021. A solid column 2053 is installed at the end of the extension plate 2051. The solid column 2053 extends along the surface of the limiting frame 202 into the groove 2021 and is fixed to the pressing plate 2052. The pressing plate 2052... The end is integrally connected with a limiting block 2054. The thickness of the limiting block 2054 is the same as the depth of the groove 2021. The thickness of the pressure plate 2052 is half the depth of the groove 2021. When the bottom of the double ladder bracket 1 is not fitted onto the limiting frame 202, the limiting block 2054 is completely embedded inside the groove 2021. The side of the pressure plate 2052 near the solid column 2053 is in contact with the inner wall of the groove 2021, ensuring that the pressure structure 205 does not protrude from the inner wall of the limiting frame 202 in the initial state and does not affect the bottom of the ladder bracket from being fitted.

[0022] After the bottom ladder frame of the double ladder support 1 is fitted into the limiting frame 202, the adjusting rod 204 is rotated in the set direction, causing the threaded sleeve 2022 to move axially. During this process, the extension plate 2051 moves accordingly, and the solid column 2053 moves the pressure plate 2052 towards the side wall of the ladder frame until the pressure plate 2052 is tightly fitted against the side wall of the ladder frame. This achieves the pressing and fixing of the bottom side wall of the ladder frame of the double ladder support 1. In addition, as the pressure plate 2052 moves towards the side wall of the ladder frame, the limiting block 2054 moves accordingly. The limiting block 2054 can limit the ladder frame in the opening direction of the limiting frame 202, preventing the double ladder support 1 from detaching from the limiting frame 202 without cause.

[0023] Before the limiting frame 202 is fitted onto the bottom of the double ladder bracket 1, the limiting block 2054 is completely embedded inside the groove 2021, while the side of the pressure plate 2052 near the solid column 2053 is in contact with the inner wall of the groove 2021.

[0024] Slope plates 203 are installed on opposite sides of the two base plates 201. The cross-section of the slope plates 203 is arranged in a triangular shape, which facilitates the transfer of the bottom of the double ladder support 1 along the bottom surface to the limiting frame 202 on the base plate 201.
