Description
Technical Field
[0001] This application relates to the technical field of asphalt pavements, and particularly to an asphalt pavement thickness detection device. Background Art
[0002] An asphalt pavement refers to various types of pavements paved by incorporating road asphalt materials into mineral materials. The asphalt binder improves the ability of the granular materials used for paving to resist damage to the pavement caused by traffic and natural factors, making the pavement smooth, less dusty, waterproof, and durable. Therefore, asphalt pavements are a type of high-grade pavement most widely used in road construction.
[0003] The pavement thickness is an important indicator for measuring the paving quality of asphalt pavements and is also an important indicator during the acceptance of asphalt pavements. Therefore, it is necessary to detect the thickness of asphalt pavements during construction. Currently, there are various thickness detection devices on the market, and most of their structures involve inserting a rod, shaft, or other components (detection components) with scales into the unhardened asphalt pavement to achieve the detection of the asphalt pavement thickness.
[0004] However, this detection method will cause asphalt to adhere to the detection components. The asphalt will block the scales, making it inconvenient to read the scales at the next measurement point. Therefore, it is necessary to clean the asphalt on the detection components at the site before detecting the next measurement point, which affects the detection efficiency. Based on this, this application proposes an asphalt pavement thickness detection device. Summary of the Invention
[0005] This application provides an asphalt pavement thickness detection device. The insertion shaft is inserted into the asphalt, while the pointer and the scale are both located above the asphalt pavement. The detection process will not cause the pointer and the scale to adhere to asphalt, will not affect the reading of the scale, reduce the number of times of cleaning asphalt, and improve the detection efficiency.
[0006] To solve the above technical problems, this application adopts the following technical solutions:
[0007] An asphalt pavement thickness detection device, comprising a bracket, a mounting plate, an insertion shaft, a pointer and a connecting rope. The bracket includes two columns and a cross beam. The two columns are connected to both ends of the cross beam. The bottom end of the column is provided with a support plate. The mounting plate is vertically connected to the lower surface of the cross beam. The mounting plate is provided with a vertical guide cylinder and a vertical chute. The notch of the vertical chute is provided with scales along the vertical direction. The top of the vertical guide cylinder and the vertical chute are both provided with guide pulleys. The insertion shaft is slidably connected in the vertical guide cylinder. The bottom end of the insertion shaft forms a tip. The pointer is slidably connected in the vertical chute through a slider. The first end of the connecting rope is connected to the top end of the insertion shaft, and the second end of the connecting rope is connected to the top end of the pointer. The connecting rope cooperates with the two guide pulleys. The first end and the second end of the connecting rope are both in a vertical state. When the bottom end of the insertion shaft is flush with the lower surface of the support plate, the pointer points to the lowest end of the scale.
[0008] During use, the insertion shaft slides in the vertical guide cylinder, the pointer slides in the vertical chute, and the two are connected by a connecting rope. When the insertion shaft is inserted downward into the asphalt pavement, the pointer is driven to rise. Since the first end and the second end of the connecting rope are both in a vertical state, the distance that the insertion shaft moves downward is equal to the distance that the pointer rises. Then, the thickness of the detected asphalt pavement can be read through the scale indicated by the pointer.
[0009] Compared with the prior art, the insertion shaft of the asphalt pavement thickness detection device is inserted into the asphalt, while the pointer and the scale are both above the asphalt pavement. During the detection process, the pointer and the scale will not stick to the asphalt, which will not affect the reading of the scale, reduce the number of times of cleaning the asphalt, and improve the detection efficiency.
[0010] In an embodiment of the present application, the vertical guide cylinder is provided with a vertical operation groove, and the insertion shaft is provided with an operation plate, and the operation plate is slidably connected in the vertical operation groove.
[0011] In an embodiment of the present application, a return spring is provided on the mounting plate. The return spring is arranged at the top end of the vertical guide cylinder, and the lower end of the return spring is connected to the operation plate.
[0012] In an embodiment of the present application, a scraping ring plate is provided at the lower end opening of the vertical guide cylinder, and the scraping ring plate abuts against the circumferential wall of the insertion shaft.
[0013] In an embodiment of the present application, the vertical chute is a T-shaped groove, the slider is a T-shaped slider, and the T-shaped slider cooperates with the T-shaped groove.
[0014] In an embodiment of the present application, the bottom end of the vertical chute is open and is connected with a plugging plate through a bolt. Brief Description of the Drawings

[0028] An embodiment of the present application provides an asphalt pavement thickness detection device, as Figure 1 , Figure 2 and Figure 3 shown, including a bracket 100, a mounting plate 200, an insertion shaft 300, a pointer 400, and a connecting rope 500. Among them, the bracket 100 is the main support component of the entire device, the mounting plate 200 is the structure for mounting other components, the insertion shaft 300 is the component inserted into the asphalt pavement, the pointer 400 is the component indicating the scale, and the connecting rope 500 is the component connecting the insertion shaft 300 and the pointer 400.
[0029] As Figure 1As shown, the bracket 100 includes two columns 110 and a crossbeam 120. The two columns 110 are connected to both ends of the crossbeam 120, forming a gantry structure. A support plate 130 is provided at the bottom end of the column 110. The area of the support plate 130 is larger than the bottom area of the column 110, playing a supporting role.
[0030] As Figure 2 shown, the mounting plate 200 is vertically connected to the lower surface of the crossbeam 120. The mounting plate 200 is provided with a vertical guiding cylinder 210 and a vertical sliding groove 220, providing two paths for vertical sliding. The notch of the vertical sliding groove 220 is provided with scales along the vertical direction, and the moving distance can be displayed through the scales. Guide pulleys 230 are provided at the tops of both the vertical guiding cylinder 210 and the vertical sliding groove 220, and the guide pulleys 230 can guide the rope.
[0031] As Figure 2 shown, the insertion shaft 300 is slidably connected within the vertical guiding cylinder 210. The bottom end of the insertion shaft 300 forms a tip, which is convenient for inserting into the asphalt.
[0032] As Figure 2 shown, the pointer 400 is slidably connected within the vertical sliding groove 220 through a slider 410. The pointer 400 can indicate the scale, facilitating reading.
[0033] As Figure 2 shown, the first end of the connecting rope 500 is connected to the top end of the insertion shaft 300, and the second end of the connecting rope 500 is connected to the top end of the pointer 400. The two guide pulleys 230 can be arranged on the side where the vertical guiding cylinder 210 and the vertical sliding groove 220 are close to each other. The connecting rope 500 cooperates with the two guide pulleys 230, making both the first end and the second end of the connecting rope 500 in a vertical state. In this way, when the insertion shaft 300 and the pointer 400 move, there will be no situation where the moving distances of the two are unequal due to the skewness of the connecting rope 500, so that the descending distance of the insertion shaft 300 is equal to the ascending distance of the pointer 400. In implementation, the connecting rope 500 is a steel wire rope or other ropes with very low extensibility, thereby reducing the error caused by the extension of the rope.
[0034] Initially, the bottom end of the insertion shaft 300 is flush with the lower surface of the support plate 130 (i.e., the upper surface of the asphalt road surface), and the pointer 400 points to the lowest end of the scale, and the scale can be displayed as 0, facilitating directly reading the distance indicated by the pointer 400.
[0035] When in use, the insertion shaft 300 slides within the vertical guiding cylinder 210, the pointer 400 slides within the vertical sliding groove 220, and the two are connected by the connecting rope 500. As Figure 2 and Figure 3As shown, when the insertion shaft 300 is inserted downward into the asphalt pavement, the pointer 400 is driven to rise. Since both the first end and the second end of the connecting rope 500 are in a vertical state, the distance that the insertion shaft 300 moves downward is equal to the distance that the pointer 400 rises. Then, the thickness of the detected asphalt pavement can be read through the scale indicated by the pointer 400.
[0036] Compared with the prior art, the insertion shaft 300 of the asphalt pavement thickness detection device is inserted into the asphalt, while the pointer 400 and the scale are both above the asphalt pavement. During the detection process, the pointer 400 and the scale will not be adhered to by the asphalt, which will not affect the reading of the scale, reduce the number of times of cleaning the asphalt, and improve the detection efficiency.
[0037] In some embodiments, as Figure 2 and Figure 4 shown, the vertical guide cylinder 210 is provided with a vertical operation groove 211, and the insertion shaft 300 is provided with an operation plate 310. The operation plate 310 is slidably connected in the vertical operation groove 211. The tester can insert the insertion shaft 300 into the asphalt pavement by pressing down the operation plate 310, which is convenient for operation.
[0038] In some embodiments, as Figure 2 and Figure 4 shown, a return spring 600 is provided on the mounting plate 200. The return spring 600 is arranged at the top end of the vertical guide cylinder 210, and the lower end of the return spring 600 can be connected to the operation plate 310 through a connecting plate. When the insertion shaft 300 moves downward, the return spring 600 is stretched. After the detection is completed, the insertion shaft 300 can be reset under the joint action of the tester and the return spring 600, and the return spring 600 can pull the insertion shaft 300 so that the bottom end of the insertion shaft 300 can be flush with the lower surface of the support plate 130 initially.
[0039] In some embodiments, a scraping ring plate (not shown in the figure) is provided at the lower end opening of the vertical guide cylinder 210. The scraping ring plate abuts against the circumferential wall of the insertion shaft 300. When the insertion shaft 300 is inserted into the asphalt pavement, some asphalt will be adhered. The asphalt can be scraped off through the scraping of the scraping ring plate, reducing the adhesion of the asphalt and facilitating the next detection.
[0040] In some embodiments, as Figure 5 shown, the vertical chute 220 is a T-shaped groove, and the slider 410 is a T-shaped slider. The T-shaped slider cooperates with the T-shaped groove, which can prevent the slider 410 from sliding out of the vertical chute 220 and ensure the smooth sliding of the slider 410.
[0041] In some embodiments, the bottom end of the vertical chute 220 is open and is connected with a plugging plate through bolts. The T-shaped slider 410 can be installed into the vertical chute 220 through the opening, and then the plugging plate is installed at the opening to achieve plugging.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
