Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a device for quickly detecting internal defects of concrete. Background Art
[0002] When the existing handheld concrete defect detection device is performing concrete defect detection, the signal line end and the connecting line end of the detection device body will first be plugged and docked with each other, and then the signal detection terminal and the concrete surface will be ultrasonically detected. The signal line at the end of the signal detection terminal will be dragged on the ground. If the signal line is caught and entangled with external objects, it is easy to cause tearing or deformation and damage between the signal line end and the connecting line end when the signal line is pulled, resulting in damage to the equipment and unusability. For this reason, we propose a rapid detection device for internal defects of concrete. Utility Model Content
[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a device for quickly detecting internal defects of concrete.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rapid detection device for internal defects of concrete, including a detection device, a winding shaft, a signal line and a detection end. A wire box for storing the signal line is installed on one side of the detection device, and circular grooves are provided on the corresponding two sides of the interior of the wire box. One end of the winding shaft is rotatably matched with the inner walls of one group of circular grooves through a movable bearing, and the other end of the winding shaft is connected and matched with the inner wall support of another group of the circular grooves through a torsion spring. The signal line passes through the detection device through a wire hole and is connected and matched with the outer periphery of the winding shaft.
[0005] Preferably, when one end of the signal wire outside the wire taking-up box is stretched outward, the winding shaft inside the wire taking-up box is in a rotating state, and the signal wire inside the wire taking-up box is in a downward conveying and unwinding state. When the signal wire is released, the winding shaft inside the wire taking-up box can reel in and store the signal wire outside the wire taking-up box through a torsion spring.
[0006] Preferably, a fixed wire clamp capable of clamping and fixing the periphery of the signal wire is arranged on the top of the wire receiving box, and a support shaft connected to the top support of the wire receiving box is installed at the bottom of the hinge mechanism of the fixed wire clamp itself.
[0007] Preferably, a hidden groove is provided on one side of the detection device, a connecting wire end integrally formed with the detection device is installed inside the hidden groove, and an installation wire end which plugs into and cooperates with the connecting wire end is installed at one end of the signal wire corresponding to the connecting wire end.
[0008] Preferably, the connecting wire end and the installing wire end are located inside the hidden groove and are in a hidden state.
[0009] Beneficial Effects
[0010] The utility model provides a device for rapid detection of internal defects of concrete, which has the following beneficial effects:
[0011] (1) A rapid detection device for internal defects of concrete. In this solution, the signal line is stored in a wire box when not in use. When the signal line and the detection end are in use, the signal line inside the wire box can be stretched outward through the detection end. When the signal line is extended to an appropriate length, the outer periphery of the signal line can be clamped and fixed by a fixed wire clamp. This can avoid the dragging and dropping of the traditional signal line and avoid sliding and cutting caused by contact with external objects, thereby achieving the effect of adjusting the signal line to an appropriate length and fixing it according to the use environment, avoiding subsequent damage caused by dragging and dropping, avoiding damage to the detection device, and ensuring the normal use of the detection device.
[0012] (2) A rapid detection device for internal defects of concrete. After use, the fixed wire clamp can be pressed to open. When the torsion spring on the winding shaft inside the wire take-up box is not squeezed and bound by the signal wire outside, the winding shaft can use the torsion spring to wind the signal wire outside the wire take-up box and recycle it into the wire take-up box for storage. The detection end can be placed on the fixed wire clamp. At this time, the fixed wire clamp is loosened to re-fix and store the signal wire. In this way, the entire signal wire can be stored in the wire take-up box. The installation wire end at the other end of the signal wire is installed with the connecting wire end inside the hidden groove. The connecting wire end and the installation wire end are hidden inside the hidden groove and will not protrude outward. In this way, the entire assembly of the detection device can be easily transported and carried, thereby reducing the external space occupancy rate. BRIEF DESCRIPTION OF THE DRAWINGS
