DETAILED DESCRIPTION
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0022] The utility model embodiment provides a concrete strength detector, such as Figure 1-4 As shown, the concrete strength detector includes: a base 1; a concrete strength detector body 2 installed on the top of the base 1 for analyzing the strength data of the concrete test block body 5, and an ultrasonic generator 3 and an ultrasonic receiver 4 are installed on the concrete strength detector body 2; an electric telescopic rod 9 slidably installed on the bottom of the base 1 for adjusting the height of the base 1, and the electric telescopic rod 9 is fixedly connected to the ultrasonic generator 3 and the ultrasonic receiver 4; and a fixing component arranged on the electric telescopic rod 9 for stabilizing the ultrasonic generator 3 and the ultrasonic receiver 4.
[0023] It should be noted that when using the existing concrete ultrasonic detector, the ultrasonic transmitter and receiver need to be attached to the concrete test block. This process requires the staff to hold the ultrasonic transmitter and receiver, which is quite laborious. At the same time, the ultrasonic transmitter and receiver need to be maintained on the same horizontal line during the process to ensure the accuracy of the test results. Close manual observation of whether the ultrasonic transmitter and receiver are on the same horizontal line is likely to produce large errors.
[0024] In the present device, when in use, the base 1 is first placed on the concrete test block body 5, the electric telescopic rod 9 is turned on to make the support rod of the electric telescopic rod 9 extend out of the support base 1, and the electric telescopic rod 9 is moved to make the two electric telescopic rods 9 close to each other. At this time, the ultrasonic generator 3 and the ultrasonic receiver 4 are both in contact with the concrete test block body 5, thereby stabilizing the ultrasonic generator 3 and the ultrasonic receiver 4, and the staff does not need to hold the ultrasonic generator 3 and the ultrasonic receiver 4, which saves manpower.
[0025] In a further preferred embodiment of the utility model, the fixing assembly includes a fixing plate 11 fixed on the electric telescopic rod 9; a threaded rod 12 threadedly mounted on the fixing plate 11; a resistance plate 13 rotatably mounted on the threaded rod 12, and a plurality of fixed pointed cones are provided on the top of the resistance plate 13; and a mesh groove 14 arranged at the bottom of the base 1, and the resistance plate 13 can contact the mesh groove 14.
[0026] In this embodiment, when the ultrasonic generator 3 and the ultrasonic receiver 4 contact the concrete test block body 5, screwing the threaded rod 12 can make the resistance plate 13 rise. At this time, the fixed pointed cone inserted into the mesh groove 14 can stabilize the left and right directions of the electric telescopic rod 9, so that the ultrasonic generator 3 and the ultrasonic receiver 4 keep in contact with the concrete test block body 5. The use of the fixed pointed cone in combination with the mesh groove 14 has higher stability than using only friction to stabilize the resistance plate 13.
[0027] In a further preferred embodiment of the utility model, a clamping block 16 is provided at the bottom of the threaded rod 12, a movable sleeve outside the clamping block 16 is provided with a limiting cylinder 17, a connecting shaft 18 is installed at the bottom of the limiting cylinder 17, an adjusting block 19 is fixed on the connecting shaft 18, and a plurality of anti-slip grooves are provided on the adjusting block 19.
[0028] In this embodiment, when the threaded rod 12 needs to be rotated, rotating the adjustment block 19 can drive the limiting cylinder 17 to rotate. At this time, the adjustment block 19 follows the limiting cylinder 17 to rotate and drives the threaded rod 12 to rotate. Compared with the person directly twisting the threaded rod 12, the comfort of the person's fingers can be increased. The anti-slip grooves can increase the friction between the person's fingers and the adjustment block 19, which facilitates the rotation of the adjustment block 19.
[0029] In a further preferred embodiment of the utility model, a slide groove 15 is provided at the bottom of the base 1, and two sliders 8 are slidably installed in the slide groove 15, and the two sliders 8 are fixedly connected to the two electric telescopic rods 9 respectively.
[0030] In this embodiment, the electric telescopic rod 9 can be stabilized by cooperating with the slide block 8 through the slide groove 15 to prevent the electric telescopic rod 9 from easily falling off the base 1. At the same time, moving the slide block 8 can adjust the distance between the two electric telescopic rods 9 so that the ultrasonic generator 3 and the ultrasonic receiver 4 can contact the concrete test block body 5 of different thicknesses.
[0031] In a further preferred embodiment of the utility model, a plurality of connecting ropes are installed at the bottom of the base 1, and a counterweight block 7 is installed at the bottom of each of the connecting ropes. An elastic pad 6 in contact with the top of the concrete test block body 5 is installed at the bottom of the base 1.
[0032] In this embodiment, the elastic pad 6 can buffer the force of the base 1 contacting the concrete test block body 5, and the counterweight block 7 can increase the weight of the base 1, thereby increasing the stability of the base 1 placed on the concrete test block body 5.
[0033] In a further preferred embodiment of the utility model, a plurality of clamping rings 20 are installed on the two electric telescopic rods 9, and the plurality of clamping rings 20 are rotatably sleeved on the two limiting cylinders 17 and the two connecting shafts 18 respectively.
[0034] In this embodiment, the clamping ring 20 can increase the stability of the limiting cylinder 17 and the connecting shaft 18 during rotation, while having little influence on the rotation of the limiting cylinder 17 and the connecting shaft 18 .
[0035] In a further preferred embodiment of the utility model, a winding shaft is rotatably installed on one side of the concrete strength detector body 2, and electric wires are installed on the ultrasonic generator 3 and the ultrasonic receiver 4, both of the electric wires are connected to the concrete strength detector body 2, and both of the electric wires are wound on the winding shaft, and a hand wheel is installed on the winding shaft.
[0036] In this embodiment, a longer electric wire can be rolled up and stored by a winding shaft, and the winding shaft can be more easily rotated by a hand wheel. Winding up a longer electric wire can prevent the electric wire from being entangled. Connecting the ultrasonic generator 3 and the ultrasonic receiver 4 by electric wire makes it easier to adjust the distance between the ultrasonic generator 3 and the ultrasonic receiver 4, thereby facilitating the detection of concrete test block bodies 5 of different thicknesses.
[0037] In a further preferred embodiment of the utility model, the output rods of the two electric telescopic rods 9 are both provided with universal wheels 10, the two universal wheels 10 are both provided with self-locking structures, and the block 16 is provided with a plurality of cut surfaces for limiting.
[0038] In this embodiment, the universal wheel 10 can more easily move the electric telescopic rod 9 to adjust the distance between the two electric telescopic rods 9, and the stability of the universal wheel 10 can be increased by the self-locking structure.
[0039] In summary, the device can detect concrete test blocks of different thicknesses, and has high stability, and does not require staff to hold a probe to detect the concrete test block detector, thus saving manpower.
[0040] Compared with the related art, the present device can be mounted outside the concrete test block body 5 by providing a base 1 and an electric telescopic rod 9, thereby stabilizing the ultrasonic generator 3 and the ultrasonic receiver 4. No manual stabilization is required, which saves manpower. By providing a fixed component, the stability of the ultrasonic generator 3 and the ultrasonic receiver 4 when they contact the concrete test block body 5 can be increased.
