Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and particularly relates to a simple road detector. Background Technique

[0002] After the road is paved, various indicators need to be detected during daily maintenance, such as road surface flatness, road surface damage, ruts, cracks, etc. For some hidden dangers that are invisible to the naked eye, it is also necessary to detect the asphalt thickness. The detection of asphalt thickness is to select multiple sampling points on the target road section and measure the thickness of the asphalt pavement in turn.

[0003] Among them, the workload of large-area sampling of asphalt pavement is very large, and generally the drilling method is selected. The available drilling tools include steel cones, hand drills, electric drills, steel nails, etc. The staff uses the drilling tools to vertically drill holes in the asphalt pavement for detection.

[0004] After drilling holes in the asphalt pavement, a long rod with scale lines is generally inserted, and the thickness of the asphalt pavement is judged by the adhered soil. However, the viscosity of the soil is affected by humidity, and the shallow soil is relatively dry and difficult to adhere to the surface of the long rod, making it difficult to position the lower surface of the drilled hole with the long rod, resulting in deviation of the depth of the asphalt pavement. For this reason, we propose a simple road detector. Content of the Utility Model

[0005] The purpose of the utility model is to provide a simple road detector, which can clearly find the lower surface of the asphalt pavement, measure the true depths of several detection points, and reduce the deviation of the detection results of the asphalt pavement depth.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A simple road inspection machine comprises a pistol drill, the drill head of the pistol drill is arranged downward, and also comprises a mounting rail slidably connected to one side of the pistol drill, a nylon rope is fixed on the side of the mounting rail away from the pistol drill, a steel ruler is fixed on the end of the nylon rope away from the mounting rail, the width of the steel ruler is smaller than the outer diameter of the drill head of the pistol drill, a cutter head is vertically fixed on the lower edge of the steel ruler, and the end of the cutter head away from the steel ruler is pointed. When inspecting an asphalt road, the drill head of the pistol drill is directed downward to a detection point, and then the mounting rail is vertically grounded, the pistol drill is started, a hole is vertically drilled at the detection point, and then , lift the pistol drill to the upper end of the installation slide rail and hang it in the air. Holding the upper end of the steel ruler, insert the lower end of the steel ruler and the cutter head downward into the drilled hole. After touching the bottom, move the steel ruler horizontally to drive the cutter head into the soil layer. The cutter head is completely immersed in the soil layer and pulled upward. It stops when the cutter head touches the lower surface of the asphalt pavement. The lower surface of the asphalt pavement can be clearly found, and the current hole depth can be read with the blade of the cutter head as the reference. Finally, pull out the cutter head and measure the depth of multiple holes in different directions and take the average value as the true depth of the current hole. Then take out the steel ruler and cutter head. In this way, the true depth of several detection points can be measured to reduce the deviation of the asphalt pavement depth detection results.

[0008] A seat ring is vertically fixed at the lower end of the installation slide rail, and the seat ring is vertically staggered with the pistol drill bit. When the installation slide rail is lowered, the seat ring can be grounded to increase the supporting surface so that the entire detection machine can be stably seated on the road surface.

[0009] A handle is fixed at the upper end of the steel ruler. The upper end of the handle is ring-shaped and the ring is fastened by one end of a nylon rope. The handle has a certain diameter, which is convenient for staff to hold and move the steel ruler.

[0010] A cursor is sleeved on the outside of the steel ruler above the cutter head. The length of the cursor is larger than the outer diameter of the pistol drill bit. The cursor can freely fall onto the upper surface of the asphalt pavement, and the current hole depth is read with the lower edge of the cursor aligned to prevent the line of sight from being disturbed by the uneven surface of the asphalt pavement.

[0011] The upper end of the pistol drill is hinged with a movable ring, and the upper end of the steel ruler is concave. After drilling is completed, the pistol drill is lifted to the upper end of the mounting slide rail and suspended in the air, and the forward rotating movable ring hangs on the concave part of the upper end of the steel ruler to support the pistol drill, and there is no need to hold the pistol drill all the time.

[0012] A rubber sleeve is also fixed on the side of the mounting rail away from the pistol drill. The upper surface of the rubber sleeve is an open structure. When storing, the lower end of the moving steel ruler and the cutter head are inserted into the rubber sleeve. The rubber sleeve is used as a cutter sleeve to prevent the cutter head from hurting people, thereby improving the safety of the detection machine.

[0013] The technical effects achieved by the utility model are:

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figures 1-5As shown, a simple road inspection machine includes a pistol drill 1. The pistol drill 1 can be a Deli series electric drill and can be equipped with a battery box. No plug board or socket is required. The drill head of the pistol drill 1 is set downward. It also includes a mounting rail 2 that is slidably connected to one side of the pistol drill 1. A nylon rope 3 is fixed to the side of the mounting rail 2 away from the pistol drill 1. A steel ruler 4 is fixed to the end of the nylon rope 3 away from the mounting rail 2. The width of the steel ruler 4 is smaller than the outer diameter of the drill head of the pistol drill 1. A cutter head 5 is vertically fixed to the lower edge of the steel ruler 4. The vertical sides of the steel ruler 4 close to the cutter head 5 are all provided with scale lines. This technical solution is a prior art and is not drawn in the figure. The end of the cutter head 5 away from the steel ruler 4 is pointed. When the pistol drill 1 is fully charged and several battery boxes are prepared, several inspection points are selected on the designated road section, the drill head of the pistol drill 1 is pointed downward to a inspection point, and then the mounting rail 2 is vertically fixed to the lower edge of the steel ruler 4. Directly, it is used to horizontally support the pistol drill 1, start the pistol drill 1, and drill vertically at the detection point until the obstruction is significantly reduced and the soil layer is clearly penetrated to a certain depth. Then, the pistol drill 1 is lifted to the upper end of the mounting slide rail 2 and suspended in the air. The upper end of the steel ruler 4 is held, and the lower end of the steel ruler 4 and the cutter head 5 are inserted downward into the drilled hole. After touching the bottom, the steel ruler 4 is moved horizontally to drive the cutter head 5 to insert into the soil layer. The nylon rope 3 is long enough to be unwound. The cutter head 5 is completely immersed in the soil layer and pulled upward. It stops when the cutter head 5 supports the lower surface of the asphalt pavement. The lower surface of the asphalt pavement can be clearly found, and the current hole depth can be read with the blade of the cutter head 5 as the reference. Finally, the cutter head 5 is pulled out to measure the depths of multiple holes in different directions and take the average value as the true depth of the current hole. The steel ruler 4 and the cutter head 5 are then taken out. In this way, the true depths of several detection points are measured to reduce the deviation of the asphalt pavement depth detection results.

[0024] The upper surface of the cutter head 5 has a cutting edge, which can easily break the soil layer, and the influence of soil moisture can be ignored. The overall width of the steel ruler 4 and the cutter head 5 is small, and can be easily inserted into the punched hole. The installation rail 2 and the traverse steel ruler 4 can be made of light alloy steel, which will not cause a significant increase in the weight of the pistol drill 1. The weight of the nylon rope 3 and the cutter head 5 can be ignored, making the entire detection machine simpler, lighter and easier to carry.

[0025] like Figure 1 and Figure 2 As shown, a seat ring 6 is vertically fixed to the lower end of the mounting slide rail 2, and the seat ring 6 is vertically offset from the drill bit of the pistol drill 1. When the mounting slide rail 2 is lowered, the seat ring 6 can be grounded to increase the supporting surface so that the entire detection machine can be stably located on the road surface.

[0026] like Figure 1 and Figure 3 As shown, a handle 7 is fixed to the upper end of the steel ruler 4. The upper end of the handle 7 is ring-shaped and the ring is fastened by one end of the nylon rope 3. The handle 7 has a certain diameter, which is convenient for the staff to hold and move the steel ruler 4.

[0027] likeFigure 1 and Figure 3 As shown, a vernier 8 is sleeved outside the steel ruler 4 at a position above the tool bit 5. The dimension of the length of the vernier 8 is larger than the dimension of the outer diameter of the drill bit of the pistol drill 1. The vernier 8 can freely fall onto the upper surface of the asphalt road surface. Aligning with the lower edge of the vernier 8, the current hole depth can be read out to prevent the line of sight from being interfered by the uneven surface of the asphalt road surface.

[0028] As Figure 1 and Figure 2 As shown, a movable ring 9 is hinged to the upper end of the pistol drill 1. The upper end of the steel ruler 4 is concave. After the drilling is completed, the pistol drill 1 is lifted to the upper end of the installation slide rail 2 to be suspended in the air. The movable ring 9 is rotated forward to hook the concave part at the upper end of the steel ruler 4 to support the pistol drill 1, so that the pistol drill 1 does not need to be held by hand all the time.

[0029] As Figure 1 , Figure 4 and Figure 5 As shown, a rubber sleeve 10 is further fixed to the side of the installation slide rail 2 away from the pistol drill 1. The upper surface of the rubber sleeve 10 is of an open structure. When storing, the lower end of the steel ruler 4 and the tool bit 5 are moved and inserted into the rubber sleeve 10. Taking the rubber sleeve 10 as a tool sheath can prevent the tool bit 5 from hurting people and improve the safety of the detector.

[0030] The working principle of the present utility model is as follows: When detecting an asphalt road, several detection points are selected at a specified section. The drill bit of the pistol drill 1 is directed downward towards a detection point, and then the installation slide rail 2 is vertically grounded to horizontally support the pistol drill 1. The pistol drill 1 is started to vertically drill a hole at the detection point until the resistance received is significantly reduced, indicating that it has penetrated into the soil layer to a certain depth.

[0031] Then, the pistol drill 1 is lifted to the upper end of the installation slide rail 2 to be suspended in the air. Hold the upper end of the steel ruler 4 by hand, and lower the lower end of the steel ruler 4 and the tool bit 5 into the drilled hole. After reaching the bottom, horizontally move the steel ruler 4 to drive the tool bit 5 to insert into the soil layer. The tool bit 5 is completely immersed in the soil layer and pulled upward. Stop when the tool bit 5 abuts against the lower surface of the asphalt road surface, so as to accurately find the lower surface of the asphalt road surface. Read the current hole depth based on the cutting edge of the tool bit 5.

[0032] Finally, the tool bit 5 is pulled out at different orientations, the depths of multiple holes are measured and averaged as the true depth of the current hole, and then the steel ruler 4 and the tool bit 5 are taken out. In this way, the true depths of several detection points are measured, reducing the deviation of the detection results of the depth of the asphalt road surface.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
