Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, and in particular to a crack detector for old houses. Background Technology

[0002] Crack detection in old buildings is an important part of assessing the structural safety and durability of buildings. It mainly involves checking the shape, distribution and development trend of cracks in parts such as walls, beams, columns and floors to determine whether there are any safety hazards in the building.

[0003] In conventional crack detection, specialized equipment is required, commonly ultrasonic testing or camera testing. Ultrasonic testing aims to determine internal defects by measuring the speed of sound wave propagation, while camera testing aims to observe the morphological characteristics and surface details of the crack to identify its type.

[0004] During the inspection, the testing equipment requires two people to operate, one to operate the equipment and the other to operate the testing equipment, which is quite inconvenient. In addition, cracks in houses are not all located in low places; some cracks are located in high places, requiring operators to stand on a platform to inspect the cracks, which poses certain safety hazards. Therefore, we urgently need a crack detector for old houses to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of existing technologies that require two people to perform the inspection, and the safety hazards of operators when inspecting at heights. Therefore, this invention proposes a crack detector for old buildings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crack detector for old buildings includes a handle and a telescopic rod fixedly mounted on the handle. A bracket is fixedly mounted on the starting section of the telescopic rod, and a mounting frame is inserted into the bracket. An operation screen is provided inside the mounting frame. A guide rail is fixedly mounted on the end section of the telescopic rod, and mounting frames are symmetrically arranged on the guide rail. A sleeve is fixedly mounted on the mounting frame, and a detection head is inserted into the sleeve. When the two mounting frames move, the two sets of sleeves move closer to or further away from each other. A clamping component is provided at the top of the telescopic rod.

[0008] For clamping the camera, preferably, the clamping member includes a rectangular plate with symmetrically opened grooves on the rectangular plate. A plug-in plate is slidably connected in the groove, and a spring is also provided in the groove, with the two ends of the spring abutting against the plug-in plate and the inner wall of the groove, respectively.

[0009] In order for the camera to be usable, a camera is further connected to the plug-in board, and the camera is electrically connected to the operation panel via a wiring harness.

[0010] To make the detection head usable, the detection head is further electrically connected to the operation panel via a connecting cable.

[0011] In order to enable the grip to rotate, preferably, the grip consists of an upper grip and a lower grip, wherein the upper grip and the lower grip are hinged at the connection point, and the telescopic rod is fixedly installed on the upper grip.

[0012] To reduce the risk of slipping, it is preferable that both the upper and lower grips are covered with anti-slip pads.

[0013] To accommodate different floor heights, the telescopic rod is preferably telescopic in length between 1.5 and 3 meters.

[0014] Compared with the prior art, this utility model provides a crack detector for old houses, which has the following advantages:

[0015] This crack detector for old buildings features a hinged design between the lower and upper handles, allowing the upper handle to move at an angle. Combined with the telescopic rod, the detection head and camera can be moved to the required detection position. The operation screen is used to detect cracks, making it suitable for detecting cracks in buildings from low to high. It also allows for single-person inspection, effectively improving inspection efficiency and reducing safety hazards caused by climbing to higher locations.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention improves detection efficiency and reduces safety hazards caused by climbing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figures 1-4 A crack detector for old houses includes a handle 1, which consists of an upper handle and a lower handle, wherein the upper handle and the lower handle are hinged together, and both the upper handle and the lower handle are covered with anti-slip pads 15.

[0026] When handle 1 is perpendicular to the wall, the instrument cannot fit tightly against the wall. Therefore, the hinge between the lower and upper handles is used to allow the upper handle to shift at an angle. It should be noted that the hinge between the upper and lower handles is damped, which can provide a certain support effect and ensure that the upper and lower handles will not shift after rotation.

[0027] Telescopic rod 2 is fixedly installed on handle 1. The telescopic rod 2 has a telescopic length range of 1.5-3 meters. The starting section of telescopic rod 2 is fixedly installed with bracket 3, and mounting frame 4 is inserted into bracket 3. An operation panel 5 is set inside mounting frame 4. Guide rail 6 is fixedly installed on the end section of telescopic rod 2. Mounting bracket 7 is symmetrically arranged on guide rail 6. Sleeve 8 is fixedly installed on mounting bracket 7. Detection head 9 is inserted into sleeve 8. When the two mounting brackets 7 move, the two sets of sleeves 8 move closer or further apart.

[0028] The detection head 9 uses ultrasonic testing. When in use, two detection heads 9 are inserted into the sleeve 8. Because the sleeve 8 is equipped with a silicone pad, the detection head 9 can be limited. The detection head 9 is connected to the operation screen 5 through a wire harness, so that the detection head 9 can be operated to detect cracks through the operation screen 5.

[0029] The top of the telescopic rod 2 is provided with a clamping component, which includes a rectangular plate 10. The rectangular plate 10 has symmetrically opened sliding grooves 11. A plug-in plate 12 is slidably connected in the sliding groove 11. A spring 13 is also provided in the sliding groove 11, and the two ends of the spring 13 abut against the inner wall of the plug-in plate 12 and the sliding groove 11, respectively. A camera 14 is plugged into the plug-in plate 12, and the camera 14 is electrically connected to the operation screen 5 through a wiring harness.

[0030] The camera 14 can be directly plugged into the connector board 12 and connected to the operation panel 5 via a wiring harness. During the ultrasonic testing process, the camera 14 can be used to observe the cracks, or only the detection head 9 or the camera 14 can be installed for single-item testing.

[0031] In this invention, the operator installs the operating screen 5 inside the mounting frame 4, and inserts the detection head 9 and camera 14 into the sleeve 8 and the plug plate 12 respectively. The detection head 9 and camera 14 are connected to the operating screen 5 using a wiring harness. The operator then adjusts the detection head 9 and camera 14 through the operating screen 5. After adjustment, the telescopic rod 2 is extended to the corresponding height, and the handle 1 is adjusted so that the detection head 9 and camera 14 simultaneously contact the crack in the wall for detection. Since the two detection heads 9 need to detect three positions during ultrasonic testing, with spacing of 100cm, 150cm, and 200cm respectively, the operator defines the detection positions through the mounting bracket 7 on the sliding guide rail 6, effectively improving the detection efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
