Description

Technical Field

[0001] This utility model relates to the field of building surface crack detection technology, and in particular to a high-level observation device for building wall cracks. Background Technology

[0002] In the construction industry, cracks appearing on concrete structures, roads, walls, etc., need to be detected and data collected in a timely manner so that they can be repaired as soon as possible.

[0003] Common instruments and equipment used for detecting and observing cracks are usually handheld or cart-type. They are fine for inspecting cracks near the surface, but when it is necessary to inspect cracks on high walls, it is often necessary to manually climb up and observe them with the help of ladders or other tools. Due to the limitations of the site and equipment, such inspection process is relatively troublesome, and manual climbing poses a significant risk. Therefore, it is necessary to design a simple and easy-to-use auxiliary device to help observe cracks at high levels. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-level observation device for building wall cracks in order to overcome the shortcomings of the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-level observation device for cracks in building walls, including a tripod base, on which a telescopic rod assembly is installed, the telescopic rod assembly including a bottom tube rod, a middle section rod and a top tube rod, and a first arc-shaped guide rod and a second arc-shaped guide rod respectively provided on the top tube rod and the bottom tube rod;

[0006] The first arc-shaped guide rod and the second arc-shaped guide rod are both provided with sliding grooves on their upper and lower end faces. A first slider is slidably connected to the sliding groove of the first arc-shaped guide rod, and a second slider is slidably connected to the sliding groove of the second arc-shaped guide rod.

[0007] A wireless camera is connected to the first slider and the inner side of the first arc-shaped guide rod by a bolt connector, and an elastic steel wire rope is connected to the lower end of the first slider by a terminal block.

[0008] The upper end of the second slider is provided with a locking ring for connecting the elastic steel wire rope.

[0009] Furthermore, the lower end of the elastic steel wire rope described in this utility model is provided with a hook, which facilitates connection and tensioning with the locking ring below.

[0010] Furthermore, the first arc-shaped guide rod and the second arc-shaped guide rod of this utility model are respectively installed on the corresponding top end rod and bottom tube rod on the same side through connecting columns.

[0011] Furthermore, the first and second arc-shaped guide rods of this invention are provided with limit protrusions at both ends to effectively prevent the corresponding sliders from slipping off.

[0012] Furthermore, the top of the top rod of this utility model is provided with an anti-detachment block, and the upper end of the anti-detachment block is also provided with a positioning light. The positioning light can help the operator below to find the lifting position as soon as possible during the overlapping process, and quickly and accurately move the camera to the observation point of the corresponding crack.

[0013] The beneficial effects of this utility model are: the high-level observation device for building wall cracks of this utility model adopts the combination of telescopic rod and two sets of arc-shaped guide rods, which can not only realize high-level observation by camera, but also achieve comprehensive observation of the crack observation point within a range of nearly 180° without any complicated electric transmission structure. It is convenient and quick to use and eliminates the safety hazards of conventional high-altitude observation. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-2 The high-level observation device for building wall cracks shown includes a tripod base 1, on which a telescopic rod assembly is installed. The telescopic rod assembly includes a bottom tube rod 2, a middle section rod 3 and a top rod 4. A first arc-shaped guide rod 5 and a second arc-shaped guide rod 6 with corresponding positions are respectively provided on the top rod 4 and the bottom tube rod 2.

[0020] The first arc-shaped guide rod 5 and the second arc-shaped guide rod 6 are both provided with sliding grooves 7 on their upper and lower end faces. A first slider 8 is slidably connected to the sliding groove 7 of the first arc-shaped guide rod 5, and a second slider 9 is slidably connected to the sliding groove 7 of the second arc-shaped guide rod 6.

[0021] A wireless camera 11 is connected to the first slider 8 and the inner side of the first arc-shaped guide rod 5 via a bolt connector 10. The lower end of the first slider 8 is connected to an elastic steel wire rope 13 via a terminal block 12.

[0022] The upper end of the second slider 9 is provided with a locking ring 14 for connecting the elastic steel wire rope 13.

[0023] The lower end of the elastic steel wire rope 13 is provided with a hook 15. The first arc-shaped guide rod 5 and the second arc-shaped guide rod 6 are respectively installed on the corresponding top rod 4 and bottom tube rod 2 on the same side via connecting post 16.

[0024] Limiting protrusions 17 are provided at both ends of the first arc-shaped guide rod 5 and the second arc-shaped guide rod 6.

[0025] The top of the top rod 4 is provided with an anti-detachment block 18, and the upper end of the anti-detachment block 18 is also provided with a positioning light 19.

[0026] Working principle:

[0027] When conducting high-level observation, first set up the device on the ground below the observation point. The tripod base serves to stabilize the chassis. Install the wireless camera and lift the telescopic rod assembly upward so that the top rod is near the high-level crack observation point (the position can be determined by the top positioning light).

[0028] Slide the second slider on the second arc-shaped guide rod to the position corresponding to the first slider above (or determine the position based on the falling position of the pre-installed elastic steel wire rope). Then connect the elastic steel wire rope to the locking ring on the second arc-shaped guide rod. At this time, the rope is taut. Since the positions of the upper and lower sliders are corresponding, the operator only needs to move the taut elastic steel wire rope to easily drive the first slider, the wireless camera, and the second slider to move synchronously within the corresponding arc range. At this time, the camera can conduct a comprehensive observation of the crack at the observation point within a range of nearly 180°.
