Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The present invention will be described below with reference to fig. 1 to 3.

A plastic track thickness detector comprises a base 1, wherein the base 1 is rectangular in shape, at least 12 points need to be measured in each field when the thickness of the plastic track is measured, and the average thickness is obtained by taking an average value. Measuring hole 2 has been seted up to base 1's center department, and measuring hole 2's shape is circular, and base 1 upper surface is kept away from center department and is provided with a plurality of pouring weights 3, and a plurality of pouring weights 3 set up around measuring hole 2, and screw and base 1 fixed connection are passed through to pouring weight 3's lower extreme, and measuring stick 6 inserts the in-process of plastic course, and base 1's stability can be guaranteed to pouring weight 3, prevents that base 1 position from taking place the skew or the condition of whole slope.

The upper end of base 1 is provided with support 4, and the upper end of support 4 is provided with fixation nut 5, and fixation nut 5 level sets up and through welding and support 4 fixed connection. Fixing nut 5 is located directly over measuring hole 2, and threaded connection has measuring stick 6 in fixing nut 5, and measuring hole 2 is passed to the lower extreme of measuring stick 6, and the outer wall of measuring stick 6 and the inner wall laminating of measuring hole 2, and measuring stick 6 carries out downstream in fixing nut 5 and measuring hole 2, and fixing nut 5's center and measuring hole 2's center are in same vertical line. Under the condition that the base 1 does not move or incline, the measuring rod 6 can vertically downwards insert into the plastic runway, thereby ensuring the accuracy of the measured data. The lower end part of the measuring rod 6 is provided with a spine part 7, and the outer wall of the spine part 7 is provided with a drilling thread 12. The spine part 7 enables the measuring rod 6 to be inserted into the plastic track more conveniently, and when the spine part 7 of the measuring rod 6 rotates in the plastic track, the drilling thread 12 enables the measuring rod 6 to slowly move downwards until the bottom end of the spine part 7 contacts the base layer.

The upper end of support 4 is provided with measuring plate 9, and measuring plate 9 is located the rear side of measuring stick 6, and measures one side that plate 9 is close to measuring stick 6 and has painted scale 10, and the measuring range of scale 10 is 0~50mm, and the top is scale 100, and the lower extreme is scale 1050. The measuring rod 6 is drawn with a measuring red line 11 on the rod body at the position of the measuring plate 9. When the bottom of 6 lower extreme spine portions 7 of measuring stick and the lower surface parallel and level of base 1, the measurement red line 11 on the measuring stick 6 just in time aligns the scale 100 on the measuring board 9, and measuring stick 6 rotates and moves down, stops measuring stick 6 when the bottom contact basal layer of spine portion 7 and continues the downstream, and the distance that measuring stick 6 moved down is the thickness of plastic course promptly, reads the scale 10 on the measuring board 9 that the measurement red line 11 on the measuring stick 6 corresponds this moment and is the thickness of plastic course promptly.

The upper end fixedly connected with hand wheel 8 of measuring stick 6, surveyor conveniently controls measuring stick 6 through hand wheel 8 and rotates, inserts it in the plastic course.
