Description
Technical Field
[0001] The utility model relates to the technical field of engineering equipment, in particular to a sleeve type asphalt loose paving thickness detection device. Background Art
[0002] When paving the road surface in the field of road construction, it is often necessary to measure the loose paving thickness of asphalt. The loose paving thickness of asphalt refers to the thickness of the uncompacted asphalt concrete surface layer when paving the asphalt concrete road surface. On the one hand, by detecting the loose paving thickness of asphalt, the compaction degree, flatness and strength of the road can be accurately determined, avoiding problems such as cracking, rutting and potholes during the use of the road, improving the service life of the road, and reducing the risk of bumps and out-of-control during vehicle driving. On the other hand, by detecting the loose paving thickness of asphalt, problems in construction can be found and adjusted in time, providing an accurate reference basis for subsequent paving, compaction and other processes.
[0003] At present, on the construction site, a measuring rod with scales is often directly used to detect the loose paving thickness of asphalt. The scales are set on the side of the measuring rod inserted into the asphalt. The measuring rod is directly inserted into the asphalt, and the corresponding reading is taken.
[0004] The above traditional method for detecting the asphalt paving thickness has the following problems: on the one hand, the scale lines are set at one end of the measuring rod inserted into the asphalt, and the scale lines will become blurred due to long-term friction, affecting subsequent use. On the other hand, to accurately measure the loose paving thickness of asphalt, it is necessary to ensure that the measuring rod is vertically inserted into the asphalt. However, when directly inserting the measuring rod into the asphalt by hand, it is very difficult to ensure the verticality, resulting in inaccurate measurement results. Summary of the Utility Model
[0005] An object of the utility model is to solve the problems that the scale lines of the measuring rod in the traditional detection of the loose paving thickness of asphalt become blurred due to long-term friction, and it is difficult to ensure the verticality of the measuring rod inserted into the asphalt when the measuring rod is held by hand.
[0006] In particular, the embodiment of the present application provides a sleeve type asphalt loose paving thickness detection device, including:
[0007] A measuring rod, one end of the measuring rod inserted into the asphalt is a tip, and the other end is provided with a handle. A scale line is arranged on the part of the measuring rod close to the handle along the length direction of the measuring rod, and the reading of the scale line gradually increases from the tip to the handle direction;
[0008] A sleeve, the tip of the probe rod is inserted into the sleeve from the first end of the sleeve. A first through hole for passing a stopper is provided on the sleeve, so as to block one end of the probe rod by the stopper when the thickness detection device is not in use. A plurality of sets of pulley combinations are sequentially arranged along the length direction of the sleeve inside the sleeve. Each set of the pulley combinations includes two directional pulleys symmetrically arranged along the radial direction of the sleeve, and the probe rod is inserted between the two directional pulleys; and
[0009] An anti-sinking base, including a second through hole for passing the sleeve. The sleeve is inserted into the second through hole from the second end opposite to the first end. The anti-sinking base has a working surface in contact with the asphalt surface to be detected. The axial direction of the sleeve and the second through hole are both perpendicular to the working surface. When the tip of the probe rod is flush with the working surface, the reading of the scale line indicates 0.
[0010] Further, each of the directional pulleys is provided with a groove for accommodating the probe rod.
[0011] Further, a first buffer pad is provided at a portion of each of the directional pulleys in contact with the probe rod.
[0012] Further, two sets of pulley combinations are arranged along the length direction of the sleeve.
[0013] Further, a fitting portion that fits with the outer surface of the probe rod is provided on a side of the stopper close to the probe rod.
[0014] Further, a second buffer pad is provided on a side of the fitting portion close to the probe rod.
[0015] Further, a horizontal calibrator provided on the sleeve-type asphalt loose paving thickness detection device is also included.
[0016] Further, a heat insulation pad is circumferentially provided on the outer side surface of the sleeve.
[0017] Further, a filter ring is also included. When the probe rod passes through the filter ring, the filter ring tightly wraps the probe rod.
[0018] Further, the material of the filter ring is high-temperature resistant rubber.
[0019] The beneficial effects of the present utility model are:
[0020] 1. After inserting the sleeve into the anti-sinking base, the sleeve is perpendicular to the working surface of the anti-sinking base. When the probe rod is inserted into the sleeve, ensure that the probe rod is vertically inserted into the asphalt. At the same time, a pulley combination is arranged in the sleeve. When the inner diameter of the sleeve is relatively large, under the limiting effect of the directional pulley, the moving direction of the probe rod in the sleeve is parallel to the axis direction of the sleeve, further ensuring the perpendicularity of the probe rod after it is inserted into the asphalt. At the same time, the scale line is set on the side of the probe rod close to the handle, avoiding the situation that the scale line is worn after the probe rod is inserted into the asphalt in the traditional measuring device.
[0021] 2. By arranging two directional pulleys in the sleeve, when the inner diameter of the sleeve is relatively large, under the limiting effect of the directional pulley, the probe rod is vertically inserted into the asphalt.
[0022] 3. By setting a filter ring, avoid the asphalt adhered to the probe rod from blocking the sleeve or the second through hole. Description of the Drawings

[0028] To make the above objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed embodiments of the present application in conjunction with the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application are shown in the drawings rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0029] The term "comprising" and "having" in this application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.
[0030] Reference to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appearing in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0031] As Figure 1 shown, in one embodiment of the utility model, the sleeve-type asphalt loose paving thickness detection device 100 includes a probe rod 1, a sleeve 2, and an anti-sinking base 3. As Figure 3 shown, one end of the probe rod 1 inserted into the asphalt is set as a tip, and the other end is a handle 4. Anti-slip threads are provided on the handle 4. Scale lines 5 are provided on the part of the probe rod 1 close to the handle 4 and are distributed along the length direction of the probe rod 1. As Figure 2 shown, the readings of the scale lines 5 gradually increase from the tip to the handle 4 direction. The tip of the probe rod 1 is inserted into the sleeve 2 from the first end of the sleeve 2. As Figure 4 shown, a first through hole for passing through a stopper 6 is provided on the sleeve 2. When the sleeve-type asphalt loose paving thickness detection 100 device of the utility model is not in use, one end of the probe rod 1 is blocked by the stopper 6 to prevent the probe rod 1 from moving within the sleeve 2. In one embodiment, the first through hole is a threaded hole and the stopper 6 is a bolt.
[0032] A pulley assembly 11 is provided inside the sleeve 2 along the length direction of the sleeve 2. Each pulley assembly 11 includes two symmetrically arranged directional pulleys 7. When the probe rod 1 is inserted between the two directional pulleys 7 and moves along the length direction of the sleeve 2, it drives the two directional pulleys 7 to rotate. When the cross-sectional diameter of the probe rod 1 is small and the cross-sectional diameter of the sleeve 2 is large, the probe rod 1 may deviate when inserted into the sleeve 2, such that the movement direction of the probe rod 1 is not parallel to the axis direction of the sleeve 2. By providing the pulley assembly 11, the probe rod 1 can move along the axis direction of the sleeve 2 within the sleeve 2.
[0033] The anti-sinking base 3 includes a second through hole for passing through the sleeve 2. The sleeve 2 is inserted into the second through hole from the second end opposite to the first end. The anti-sinking base 3 has a working surface that abuts against the asphalt surface to be detected. The axial direction of the sleeve 2 and the second through hole are both perpendicular to the working surface. When the tip of the probe rod 1 is flush with the working surface, the reading of the scale line indicates 0.
[0034] In the sleeve-type asphalt loose paving thickness detection device of the present utility model, after the sleeve 2 is inserted onto the anti-sinking base 3, the sleeve 2 is perpendicular to the working surface of the anti-sinking base 3. When the probe rod 1 is inserted into the sleeve 2, it is ensured that the probe rod 1 is vertically inserted into the asphalt. At the same time, a pulley combination 11 is arranged inside the sleeve 2. When the inner diameter of the sleeve 2 is relatively large, under the limiting action of the directional pulley 7, the moving direction of the probe rod 1 inside the sleeve 2 is parallel to the axial direction of the sleeve 2, further ensuring the perpendicularity of the probe rod 1 after it is inserted into the asphalt. At the same time, the scale line 5 is arranged on the side of the probe rod 1 close to the handle 4, avoiding the situation where the scale line 5 is worn after the probe rod 1 is inserted into the asphalt in the traditional measuring device.
[0035] In one embodiment, an internal thread is provided in the second through hole, and an external thread is provided on the outer side wall of the sleeve 2. The sleeve 2 is threadedly connected to the second through hole. In another embodiment, the second through hole is a polygonal hole, and the outer side wall of the sleeve 2 is a polygon adapted to the second through hole. The sleeve 2 is fixed in the second through hole by the engagement between the polygons. In other embodiments, the sleeve 2 and the anti-sinking base 3 can be an integral body.
[0036] Particularly, each directional pulley 7 is provided with a groove that can accommodate the probe rod 1. When the probe rod 1 passes through the directional pulley 7, under the limiting action of the groove, the probe rod 1 can move in a direction parallel to the axis of the sleeve 2, avoiding the deviation of the moving direction. At the same time, a first buffer pad is arranged at the part where each directional pulley 7 contacts the probe rod 1. Preventing the long-term contact friction between the probe rod 1 and the directional pulley 7 from causing friction damage to both, and extending the overall service life of the sleeve-type asphalt loose paving thickness detection device 100 of the present utility model.
[0037] In order to further ensure that the probe rod 1 can move along the axial direction of the sleeve 2, two groups of pulley combinations 11 are arranged along the length direction of the sleeve 2. Two points for restricting the moving direction of the probe rod 1 are arranged in the length direction of the probe rod 1. While maximizing the moving direction of the probe rod 1, the overall cost of the device is also the lowest. In other embodiments, three or more groups of pulley combinations 11 can also be arranged along the length direction of the sleeve 2. Although the device cost increases, the limiting effect on the moving direction of the probe rod 1 is stronger, and it can be selected according to the actual situation. There is no limitation here, and all belong to the protection scope of the present utility model.
[0038] To ensure that the probe rod 1 moves along the axial direction of the sleeve 2 within the sleeve 2, two limiting plates perpendicular to the axial direction of the sleeve 2 can also be arranged along the length direction of the sleeve 2 within the sleeve 2. Corresponding limiting holes are provided on the two limiting plates, and the diameters of the two limiting holes are slightly larger than the cross-sectional diameter of the probe rod 1. When the probe rod 1 moves in the two limiting holes simultaneously, the moving direction of the probe rod 1 is parallel to the axial direction of the sleeve 2. The number of limiting plates can be two or more, and can be flexibly selected according to the situation.
[0039] On one side of the stopper 6 close to the probe rod 1, a mating portion 8 that mates with the outer surface of the probe rod 1 is provided. When the outer side wall of the probe rod 1 is cylindrical, the mating portion 8 includes a U-shaped groove that mates with the cylindrical outer side wall. In one embodiment, the mating portion 8 is a U-shaped plate including the above U-shaped groove. In another embodiment, the mating portion 8 is a square block including the above U-shaped groove. By providing the mating portion 8, the stopper 6 can better fit the probe rod 1, improving the stopping effect of the stopper 6. To prevent the stopper 6 from damaging the probe rod 1, a second buffer pad is provided on the side of the mating portion 8 close to the probe rod 1.
[0040] The asphalt loose paving thickness detection device of the present utility model further includes a level calibrator 9 provided on the sleeve 2 or the anti-sinking base 3. For the convenience of simplifying the horizontal calibration, in one embodiment, a circular bubble level calibrator 9 is attached to the base. When the bubble in the calibrator is located at the center position of the circular calibrator, the anti-sinking base 3 is in a horizontal state. By providing the level calibrator 9, when the surface of the asphalt is slightly uneven, the anti-sinking base 3 is also uneven when placed on the asphalt. Through the calibration of the level calibrator 9, it is ensured that the probe rod 1 is vertically inserted into the asphalt, improving the accuracy of the detection.
[0041] After the asphalt is loosely paved on the road surface, the temperature of the asphalt surface is relatively high. When the temperature of the asphalt is conducted to the sleeve 2 by heat conduction, in order to avoid temperature scalding, a heat insulation pad is circumferentially arranged on the outer side surface of the sleeve 2.
[0042] The asphalt loose paving thickness detection device of the present utility model further includes a filter ring 10. Since the viscosity of the asphalt is relatively high after melting, when the probe rod 1 is inserted into the asphalt and then pulled out, a lot of asphalt will adhere to the probe rod 1. When the asphalt adhering to the probe rod 1 enters the sleeve 2 or the second through hole, it may cause blockage inside the sleeve 2 or the second through hole. By providing the filter ring 10, when the probe rod 1 is pulled out from the asphalt, it will first pass through the filter ring 10. Since the filter ring 10 tightly wraps the probe rod 1, the asphalt adhering to the probe rod 1 is filtered out, avoiding blockage. In one embodiment, the filter ring 10 is arranged at the second end of the sleeve 2. As Figure 3 shown, in another embodiment, the filter ring 10 is arranged on the side of the second through hole close to the sleeve 2. Since the temperature of the asphalt is relatively high, the material of the filter ring 10 can be made of high-temperature resistant rubber.
[0043] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
