Description

Technical Field

[0001] The utility model relates to the technical field of measuring the pavement false paving thickness, in particular to a digital display type pavement false paving thickness rapid measuring instrument. Background Art

[0002] The literal meaning of highway is a public road or a public transportation road. Cars, bicycles, rickshaws, horse-drawn carriages and other vehicles and pedestrians can use it. Of course, different highways have different restrictions. It is also called a road in the folk. Nowadays, highway construction generally requires the use of asphalt, crushed stone and other materials to pave the road. When paving the road, the thickness and flatness of the paving need to be tested. Therefore, when constructing the road, its thickness and flatness need to be measured.

[0003] When testing the paving thickness of existing roads, the tester needs to squat to observe the loose paving thickness. Since the newly laid asphalt material has not yet solidified, there will be strong irritating gas emissions. Because it is necessary to test multiple sections of the road, long-term testing will cause certain harm to the health of the testers, and it is not easy to observe the flatness of the road surface during the test.

[0004] Therefore, we proposed a digital display type pavement loose paving thickness rapid determination instrument, in order to solve the above-mentioned problems. Summary of the invention

[0005] The utility model provides a digital display type road surface loose paving thickness rapid measuring instrument, which solves the problem that when detecting the paving thickness of existing roads mentioned in the above background technology, a measuring worker needs to half squat to observe the loose paving thickness. Since the newly laid asphalt material has not yet solidified and fixed, there will be strong irritating gas emission. Since it is necessary to detect multiple sections of the road, long-term detection will cause certain harm to the health of the detection personnel, and it is not easy to observe the flatness of the road surface during detection.

[0006] The utility model provides the following technical solutions: a digital display type road surface false paving thickness rapid measuring instrument, comprising a fixed block and a vertical measuring rod fixedly installed at the lower end of the fixed block, a horizontal measuring rod slidably connected to the vertical measuring rod, connecting rod one is fixedly installed on the lower walls on both sides of the fixed block, a connecting plate is commonly fixedly installed on one end of the two connecting rods one, the vertical measuring rod is fixedly installed on the connecting plate, connecting rod two is fixedly installed on the upper walls on both sides of the horizontal measuring rod, the two connecting rods two are slidably connected to the connecting plate, a level bubble is fixedly installed on the upper end of the fixed block, a digital display displacement sensor is fixedly installed on the upper end of the fixed block, and a measuring component is installed on the side wall of the fixed block.

[0007] As an optional solution described in the utility model, wherein: a connecting block is fixedly installed on the side wall of the fixed block, and the measuring component includes a ruler fixedly installed on the side of the connecting block, and a reader is slidably connected to the ruler.

[0008] As an optional solution described in the utility model, wherein: a connecting piece is fixedly installed at the connection between the connecting plate and the connecting rod 1 and the vertical measuring rod, and a limiting sleeve is fixedly installed at the upper end of the connecting piece of the vertical measuring rod.

[0009] As an optional solution described in the utility model, wherein: the side wall of the connecting plate is provided with an opening, and the reader is movably connected in the opening.

[0010] As an optional solution described in the utility model, a conical probe is fixedly installed on the lower end of the vertical measuring rod, and a limiting ring is fixedly installed on the side wall of the conical probe.

[0011] As an optional solution described in the utility model, wherein: a hand ring is fixedly installed on the upper end of the fixed block, the two connecting rods 1 have the same length, and the two connecting rods 2 have the same length.

[0012] The utility model has the following beneficial effects:

[0013] When measuring the loose pavement thickness, insert the conical probe at the front end of the vertical measuring rod into the loose pavement mixture, ensure that the instrument is in a horizontal state by observing the level bubble, and slide the transverse measuring rod upward along the vertical measuring rod. When the front end of the vertical measuring rod is inserted to the top surface of the lower supporting layer, the transverse measuring rod is located at the top of the loose pavement layer. The distance moved by the transverse measuring rod is displayed by the digital displacement sensor. After use, the transverse measuring rod returns to the upper end of the limit ring of the conical probe under the action of gravity to complete the detection. Compared with the traditional measuring rod detection, the digital pavement loose pavement thickness rapid measuring instrument does not require the inspector to half-squat to observe the loose pavement thickness, which reduces the harm of the irritating odor of asphalt paving, enhances the technical personnel's willingness to detect, and improves the qualified rate of pavement thickness and flatness.

[0014] It can measure data of different loose paving thicknesses, not limited to the fixed thickness required by the fixed loose paving coefficient summarized in the test section. For example, the cross slope of the bridge deck in some projects is different, but the cross slope of the asphalt layer must be unified, so there is a difference in the virtual paving thickness of the paver on both sides of the variable cross-section of the bridge deck cross slope. This digital display virtual paving thickness meter is movable, which solves this problem well and improves the paving effect.

[0015] The side rod of the inspection tool is equipped with a level bubble, and the vertical perpendicularity of the paving surface is adjusted according to the level bubble. This solves the error of whether the drill is perpendicular to the paving surface caused by human factors in traditional drill insertion and improves the measurement accuracy.
