Description

Technical Field

[0001] The utility model relates to the technical field of concrete monitoring, in particular to a concrete crack monitoring device. Background Art

[0002] Concrete is an engineering composite material made of cementitious materials, aggregates such as sand and stone, water and possible admixtures and additives in a certain proportion. It is widely used in construction and civil engineering to construct the main structure of buildings or to pave the ground.

[0003] Concrete cracks are physical structural changes caused by internal and external factors in concrete structures, and cracks are the main reason for the reduction of bearing capacity, durability and waterproofness of concrete structures. Some cracks may continue to crack, which will have a serious impact on the quality of the project. Therefore, it is necessary to monitor the development of cracks through concrete crack monitoring devices and take timely remedial measures.

[0004] Current crack monitoring devices mostly use visual observation in conjunction with measuring instruments or electronic instruments for monitoring, which require manual operation and can generally only detect concrete at low locations. When located on high walls, manual operation will be more troublesome and prone to safety accidents, greatly reducing its practicality. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] As attached Figure 1 and attached Figure 2 As shown, a concrete crack monitoring device includes a display host 1 and a connected measuring probe 2, wherein the display host 1 includes a display screen, a control panel and a power supply, and the measuring probe 2 is electrically connected to the display host 1 through a wire, and a rectangular block 3 is provided on the side wall of one end of the wire close to the measuring probe 2, and a detachable connecting mechanism 4 is sleeved on the outer side of the wire at the rectangular block 3, and a connecting rod 5 is provided at the lower end of the connecting mechanism 4, and a rotating drum 6 is rotatably sleeved on the side wall of the connecting rod 5, and an extension rod 7 is connected to the outer side wall of the rotating drum 6.

[0028] Through the above structure, the connection mechanism 4 can be installed on the wire on one side of the measuring probe 2, and the position of the measuring probe 2 can be changed by holding the extension rod 7 to detect concrete cracks at high places without climbing, which is highly safe.

[0029] Embodiment 2

[0030] Based on Example 1, please refer to the attached Figure 3 and attached Figure 4

[0031] The connecting mechanism 4 includes relative arc plates 8 sleeved outside the wire, and the side walls of the arc plates 8 facing the wire are provided with slots 9 that cooperate with the rectangular block 3. The outer walls at both ends of the arc plates 8 are provided with extension plates 10, and screws 11 are inserted between the relative extension plates 10. Nuts 12 are threadedly sleeved at both ends of the screws 11.

[0032] Through the above structure, the connection mechanism 4 is sleeved on the outside of the wire by tightening the nut 12. Since the arc plate 8 of the connection mechanism 4 cooperates with the rectangular block 3 on the wire, the position of the connection mechanism 4 after installation is fixed to avoid rotation.

[0033] One of the arc-shaped plates 8 has a front and rear connecting plate 13 at its lower end, the connecting rod 5 is fixedly arranged between the connecting plates 13, the side wall of the connecting plate 13 is evenly provided with a plurality of notches along the circumferential direction, and the inner wall of the rotating drum 6 is evenly provided with a plurality of protrusions matching the notches along the circumferential direction; the protrusions are made of rubber material, and the size of the protrusions is smaller than the notches.

[0034] Through the above structure, the rotating drum 6 can be rotated outside the connecting rod 5 by external force and the angle can be fixed, so that the angle of the measuring probe 2 can be adjusted, which is convenient for detecting concrete surfaces with different inclination angles.

[0035] The extension rod 7 is a telescopic rod structure composed of a plurality of connecting rods that are sleeved in sequence; the maximum length of the extension rod 7 is the same as the length of the wire, and the lower end is a convex curved structure.

[0036] The above structure facilitates storage, and the extension rod 7 can be pulled out to a corresponding length as needed without scratching the user.

[0037] Through the above structure,

[0038] It is worth noting that the display host 1, measuring probe 2 and their supporting power supplies and control switches mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art without further elaboration.

[0039] The specific method of use is as follows: when monitoring concrete cracks at a low location, it is only necessary to hold the wire at the measuring probe 2 and use it to transmit the crack information detected by the measuring probe 2 to the display host 1. When detecting concrete cracks at a high location, first sleeve the arc plate 8 of the connecting mechanism 4 on the outside of the wire corresponding to the rectangular block 3, tighten the nut 12 to fix the position of the arc plate 8. Since the slot 9 in the arc plate 8 of the connecting mechanism 4 cooperates with the rectangular block 3 on the wire, the position of the connecting mechanism 4 after installation is fixed to avoid rotation. The rotating drum 6 is rotated by manpower to change the angle formed by the extension rod 7 and the arc plate 8, that is, when holding the extension rod, the end of the measuring probe 2 can be parallel to the concrete surface to be measured. The extension rod 7 can be pulled out to a corresponding length as needed to detect cracks on the concrete surface to be measured. There is no need to climb to a high place, and the safety is high. It can monitor whether the cracks in the concrete within the corresponding range are in a safe state.
