Description

Technical Field

[0001] This utility model belongs to the technical field of building inspection equipment, and in particular relates to a portable crack and deformation detector for engineering structures. Background Technology

[0002] The portable engineering structure crack and deformation detector is a lightweight testing device designed specifically for safety monitoring of engineering structures such as bridges, buildings, tunnels, and dams. It integrates core technologies such as optical imaging, laser ranging, strain sensing, and GPS / BeiDou positioning. It can quickly collect key parameters such as crack width / length / depth, structural displacement, settlement, and strain. Features include compact size, long battery life, easy operation (supporting touchscreen operation and wireless data transmission), and accuracy meeting engineering testing standards. It enables real-time on-site monitoring, automatic data storage and analysis, and intuitive presentation of structural damage evolution trends. This provides accurate data support for structural safety assessment, defect diagnosis, and repair and reinforcement decisions, and is widely applicable to engineering inspections, final acceptance, and long-term health monitoring.

[0003] Because the probes of existing portable engineering structure crack and deformation detectors need to be held by hand while bending over or squatting, continuous bending can easily injure the user's back, and continuous squatting consumes a lot of physical strength, resulting in the relatively low practicality of conventional portable engineering structure crack and deformation detectors.

[0004] To address these issues, we propose a portable crack and deformation detector for engineering structures. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low practicality of conventional portable crack and deformation detectors for engineering structures, and to propose a portable crack and deformation detector for engineering structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A portable crack and deformation detector for engineering structures includes a probe head. A movable sleeve is slidably mounted on the outside of the probe head. A portal frame is fixedly connected to the outside of the movable sleeve. A first roller is rotatably mounted on the lower end of the portal frame. A movable column is fixedly connected to the upper end of the probe head, and the movable column slides through the portal frame. An operating lever is fixedly connected to the upper end of the movable column. Holding the operating lever upwards forces the movable column, which in turn forces the probe head upwards. The probe head then forces the portal frame and the movable sleeve upwards, aligning the probe head with a target ground crack. During this process, the first roller rolls along the ground to protect the probe head and prevent wear. Releasing the operating lever lowers the movable sleeve, bringing the probe head closer to the crack for detection. Holding the operating lever by hand avoids bending over to inspect the ground target.

[0007] Preferably, a booster spring is fitted around the movable column. The booster spring is sleeved on the outside of the movable column, with its upper end fixedly connected to the movable column and its lower end fixedly connected to the gantry frame. The spring force acts upwards on the probe, reducing unnecessary pressure on the ground and thus minimizing pressure damage from stones, thereby protecting the probe.

[0008] Preferably, the probe head includes a probe body, and a second roller is symmetrically and rotatably mounted on the lower part of the probe body. The second roller provides rolling support for the probe body, preventing ground wear on the probe body.

[0009] Preferably, the movable sleeve includes a sleeve body, a connecting plate is fixedly connected to the side of the sleeve body, and the sleeve body is slidably fitted onto the probe body. The probe body guides the sleeve body to slide.

[0010] Preferably, the gantry frame includes a frame body, with a bearing seat fixedly connected to the lower end of the frame body. The first roller is rotatably connected to the bearing seat, and the sleeve is fixedly connected to the frame body. The bearing seat guides the rotation of the first roller, and the frame body guides the lifting and lowering of the movable column.

[0011] Preferably, the movable column includes a column body that slides through the frame. The lower end of the column body is fixedly connected to the probe body. The assist spring is movably sleeved on the outside of the column body. A connecting plate is fixedly connected to the upper end of the column body. The lower end of the operating rod is fixedly connected to the upper end of the connecting plate. The upper end of the assist spring is fixedly connected to the connecting plate, and the lower end of the assist spring is fixedly connected to the frame body. The lower end of the operating rod is fixedly connected to the connecting plate. When the operating rod is lifted upward, it acts upward on the connecting plate, which in turn acts upward on the column body. This causes the column body to act upward on the probe body, causing the frame body to slide down the column body to return to its original position.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Hold the operating lever upwards to apply force to the movable column, which in turn applies force upwards to the probe head. The probe head then applies force upwards to the gantry frame and movable sleeve, aligning the probe head with the target ground crack. During this process, the first roller rolls along the ground to protect the probe head and prevent it from wearing down. Release the operating lever to lower the movable sleeve, bringing the probe head closer to the crack for detection. Holding the operating lever by hand avoids bending over to inspect the ground target.

[0013] 2. The upward force of the assist spring is used to reduce the unnecessary pressure of the probe on the ground, thereby reducing the pressure damage to the probe caused by stones on the ground and facilitating the protection of the probe. Attached Figure Description

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

[0017] like Figure 1 As shown, a portable engineering structure crack and deformation detector includes a probe head 2, a movable sleeve 3 slidably mounted on the outside of the probe head 2, a portal frame 4 fixedly connected to the outside of the movable sleeve 3, a first roller 7 rotatably mounted on the lower end of the portal frame 4, and a movable column 5 fixedly connected to the upper end of the probe head 2. The movable column 5 slides through the portal frame 4, and an operating lever 1 is fixedly connected to the upper end of the movable column 5. Holding the operating lever 1 upwards acts on the movable column 5, which in turn acts upwards on the probe head 2, which in turn acts upwards on the portal frame 4 and the movable sleeve 3, aligning the probe head 2 with the target ground crack. During this process, the first roller 7 rolls along the ground to protect the probe head 2 and prevent wear between the probe head 2 and the ground. Releasing the operating lever 1 lowers the movable sleeve 3, bringing the probe head 2 closer to the crack for detection.

[0018] like Figure 1 As shown, a booster spring 6 is fitted around the outside of the movable column 5. The upper end of the booster spring 6 is fixedly connected to the movable column 5, and the lower end of the booster spring 6 is fixedly connected to the gantry frame 4. The elastic force of the booster spring 6 acts upward on the probe head 2, reducing unnecessary pressure on the ground from the probe head 2, thereby reducing the pressure damage to the probe head 2 caused by stones on the ground.

[0019] like Figure 1 and 2 As shown, the probe head 2 includes a probe body 21, and a second roller 22 is symmetrically and rotatably mounted on the lower part of the probe body 21. The second roller 22 provides rolling support for the probe body 21, preventing ground wear on the probe body 21.

[0020] like Figure 1 , 2 As shown in Figure 3, the movable sleeve 3 includes a sleeve body 31, with a connecting plate 32 fixedly connected to the side of the sleeve body 31. The sleeve body 31 is slidably sleeved on the outside of the probe body 21. The probe body 21 guides the sleeve body 31 to slide.

[0021] like Figure 1 , 3 As shown in Figure 4, the portal frame 4 includes a frame body 41, with a bearing seat 42 fixedly connected to the lower end of the frame body 41. The first roller 7 is rotatably connected to the bearing seat 42, and the sleeve 31 is fixedly connected to the frame body 41. The bearing seat 42 guides the first roller 7 to rotate, and the frame body 41 guides the movable column 5 to rise and fall.

[0022] like Figure 1 , 2 As shown in Figures 4 and 5, the movable column 5 includes a column body 51 that slides through the frame 41. The lower end of the column body 51 is fixedly connected to the probe body 21. A support spring 6 is movably sleeved on the outside of the column body 51. A connecting plate 52 is fixedly connected to the upper end of the column body 51. The lower end of the operating lever 1 is fixedly connected to the upper end of the connecting plate 52. The upper end of the support spring 6 is fixedly connected to the connecting plate 52, and the lower end of the support spring 6 is fixedly connected to the frame 41. The lower end of the operating lever 1 is fixedly connected to the connecting plate 52. When the operating lever 1 is lifted upward, it acts upward on the connecting plate 52, which in turn acts upward on the column body 51. This causes the column body 51 to act upward on the probe body 21, causing the frame 41 to slide down along the column body 51 to return to its original position.

[0023] Working principle: The hand-held operating lever 1 acts upward on the movable column 5, which in turn acts upward on the probe head 2. The probe head 2 then acts upward on the gantry frame 4 and the movable sleeve 3, aligning the probe head 2 with the target ground crack. During this process, the first roller 7 rolls along the ground to protect the probe head 2 and prevent it from wearing down. Releasing the operating lever 1 lowers the movable sleeve 3, allowing the probe head 2 to approach the crack for detection.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0025] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
