Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar diameter measurement, and in particular relates to a construction steel bar diameter measuring device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is mainly circular. In construction, in order to ensure the quality of the rebar, it is necessary to measure the diameter of the rebar to ensure the quality of the finished product.

[0003] When the existing measuring device detects the diameter of steel bars, once there are impurities on the surface of the steel bars, the detection effect will be inaccurate. The current treatment method is to manually remove the impurities on the surface of the steel bars, but due to factors such as the length and number of the steel bars themselves, the cleaning efficiency of the steel bars is low. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0006] Preferably, the connecting member is a mounting bracket, and an adjustment slot for vertical movement of the adjusting rod is provided on the top of the mounting bracket; the cleaning part is a wire sleeve mounted on the adjusting rod and the fixed rod, wherein at least two wire sleeves are provided on the adjusting rod and the fixed rod, and when a single wire sleeve becomes ineffective due to long-term use, another wire sleeve can be replaced to continue cleaning.

[0007] Preferably, the guide member includes a guide wheel installed on both sides of the machine body, the inner side of the top of which is connected to the guide wheel, wherein the top section of the guide wheel is flush with the top section of the fixing rod.

[0008] Preferably, the length of a single steel wire sleeve is equal to the length of the guide wheel, thereby ensuring that each steel wire sleeve can clean the steel bars.

[0009] Preferably, a screw hole is provided on the top surface of the mounting frame, and an adjusting bolt is screwed into the screw hole. The adjusting bolt is against the adjusting rod, and a spring is also provided between the inner bottom end surface of the adjusting groove and the adjusting rod. When it is necessary to increase the spacing between the adjusting rod and the fixing rod according to the diameter of the steel bar, the adjusting bolt is rotated toward the outside of the mounting frame, and the spring rebounds at this time to lift the adjusting rod. Conversely, the adjusting bolt is rotated toward the adjusting rod to squeeze the adjusting rod and the spring.

[0010] Preferably, an integrated limiting plate is formed at both ends of the guide wheel, and the diameter of the limiting plate is larger than the diameter of the guide wheel, so as to prevent the steel bars from falling, and the guide wheel is rotatably connected to the guide wheel through an axis.

[0011] Preferably, a test head is installed on the side wall of the upper groove of the body, and a laser is emitted by the test head to detect the diameter of the steel bars passing through the groove. This technology is existing technology and will not be further described here. A support is also installed on the bottom end surface of the body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the designed cleaning component, impurities on the surface of the steel bar can be scraped off to ensure the accuracy of the steel bar diameter detection. At the same time, the cleaning component can make corresponding adjustments according to steel bars of different diameters to meet different cleaning needs. It has high practicality as a whole and improves the shortcomings of existing measuring devices in use. BRIEF DESCRIPTION OF THE DRAWINGS
