Description

Technical Field

[0001] This utility model is a device for detecting the amount of asphalt spread, belonging to the field of asphalt spread quantity detection. Background Technology

[0002] For the construction of tack coat, primer coat, and seal coat on highway pavements, asphalt is sprayed using an asphalt distributor. According to the E60-2008 specification, the test of the asphalt spreading amount during asphalt spraying is to place two sample pans with an area of ​​not less than 0.1 m2 at any position within the spreading width. After the distributor has spread the asphalt, the sample pans containing asphalt are removed from the road surface to weigh and calculate the weight. Then, the blank space left by the sample pans is manually filled in the original position. This testing method is implemented in accordance with the E60-2008 specification.

[0003] In a device for detecting the amount of asphalt spread, patent number CN201220250423.5, there is a detection method that uses this procedure. When asphalt is sprayed onto the sample plate, it will cause splashing, which will lead to the detection result being too small. Therefore, the patent proposes to collect the asphalt evenly sprayed from one of the nozzles while the vehicle is in motion, and then calculate the square asphalt spread amount using a formula.

[0004] However, the collection method described in the patent does not specify the installation structure of the sample receiving dish, that is, it does not describe the nozzle and sample receiving dish during vehicle movement, which makes it impossible to reliably ensure that the nozzle and sample receiving dish are connected together to complete the final asphalt collection. Therefore, this application proposes a device for detecting the amount of asphalt spread that facilitates fixing the sample receiving dish. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for detecting the amount of asphalt spread.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A device for detecting the amount of asphalt spread includes an asphalt spreader truck and a collection cylinder. The rear of the asphalt spreader truck is connected to a detection nozzle via a pipe. Detection nozzles are evenly arranged at the bottom end of the detection nozzle, with one of the detection nozzles corresponding to the collection cylinder. A first fixed plate and a second fixed plate, arranged symmetrically, are fixed on the detection nozzle. A double-axis screw is provided between the first fixed plate and the second fixed plate. Two threaded clamps are threaded onto the double-axis screw. The collection cylinder is clamped between the threaded clamps. Ground is provided below the asphalt spreader truck.

[0008] Furthermore, an arc-shaped clamping plate is fixedly provided on the inner side of each threaded clamping plate, one end of the dual-axis lead screw passes through the first fixed plate, and a circular plate is fixedly provided at the through end of the dual-axis lead screw. A circular rod is fixedly provided on the circular plate, and the circular plate and the circular rod form a manual turntable.

[0009] Furthermore, a bearing is fitted at the other end of the dual-axis lead screw, the bearing is fixed on the inner side of the second fixed plate, a traction rod is fixed between the first fixed plate and the second fixed plate, and the threaded clamp is slidably fitted on the traction rod.

[0010] Furthermore, a bottom support assembly is fixedly provided at the bottom end of the detection nozzle. The bottom support assembly includes a deflector rod fixed at the bottom end of the detection nozzle, and a support base plate is fixedly provided at the bottom end of the deflector rod. The collecting cylinder is supported at the bottom end of the support base plate.

[0012] Furthermore, multiple mounting plates are fixedly provided on the annular plate, and the mounting plates are fixed to the inner side of the collecting cylinder with screws.

[0013] The beneficial effects of this utility model are:

[0014] First, the outermost nozzle is the corresponding collection cylinder for the detection nozzle. The collection cylinder is clamped by a designed threaded clamp to ensure that the asphalt sprayed from the detection nozzle is collected more stably inside the collection cylinder.

[0015] Adjust the flow rate of all the testing nozzles on the asphalt spreader to be consistent to ensure uniform spreading. As the asphalt spreader travels on the ground at a constant speed, all the asphalt sprayed from the testing nozzles is collected in the collection cylinder. The asphalt sprayed from the other nozzles is evenly spread on the road surface. The area of ​​the road surface that was not sprayed with asphalt is calculated, and the amount of unsprayed asphalt in that area is the amount of asphalt collected in the collection cylinder.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a device for detecting the amount of asphalt spread, including an asphalt spreader 1 and a collection cylinder 4. The rear of the asphalt spreader 1 is connected to a detection nozzle 2 via a pipe. The bottom end of the detection nozzle 2 is uniformly provided with detection nozzles 3, one of which corresponds to the collection cylinder 4. A first fixing plate 5 and a second fixing plate 6 are fixedly arranged symmetrically on the detection nozzle 2. A double-axis screw 7 is provided between the first fixing plate 5 and the second fixing plate 6. Two threaded clamps 8 are threaded on the double-axis screw 7. The collection cylinder 4 is clamped between the threaded clamps 8. A ground 18 is provided below the asphalt spreader 1.

[0025] See Figure 1-3The inner sides of the threaded clamping plates 8 are all fixed with arc-shaped clamping plates 9. One end of the dual-axis screw 7 passes through the first fixed plate 5, and a circular plate 19 is fixed at the through end of the dual-axis screw 7. A circular rod 20 is fixed on the circular plate 19. The circular plate 19 and the circular rod 20 form a manual turntable 10. The other end of the dual-axis screw 7 is fitted with a bearing 11, which is fixed to the inner side of the second fixed plate 6. A traction rod 12 is fixed between the first fixed plate 5 and the second fixed plate 6. The threaded clamping plates 8 are slidably fitted on the traction rod 12. Manually rotating the manual turntable 10 drives the dual-axis screw 7 to rotate, which in turn drives the two threaded clamping plates 8 on the dual-axis screw 7 to move away from or towards each other, driving the two arc-shaped clamping plates 9 to move away from or towards each other. The arc-shaped clamping plates 9 clamp the sides of the collecting cylinder 4, completing the fixation of the collecting cylinder 4 and ensuring stability during collection. The designed bearing ensures the rotational stability of the corresponding designed components, and the designed traction rod ensures that the designed threaded clamping plates 8 can move horizontally relative to each other normally.

[0026] See Figure 2 The bottom end of the detection nozzle 2 is fixedly provided with a bottom support assembly. The bottom support assembly includes a deflector rod 13 fixed to the bottom end of the detection nozzle 2. The bottom end of the deflector rod 13 is fixedly provided with a support base plate 14. The collection cylinder 4 is supported at the bottom end of the support base plate 14. Before the collection cylinder 4 is clamped on the side, it is necessary for personnel to manually support the collection cylinder 4 on the support base plate 14. Therefore, the stability of the support base plate 14 is further increased when collecting asphalt.

[0027] See Figure 3-4 The inner side of the collection cylinder 4 is provided with a circular ring plate 15. A soft rubber sealing ring 16 is attached to the inner side of the circular ring plate 15. Multiple mounting pieces 17 are fixed on the circular ring plate 15. The mounting pieces 17 are fixed to the inner side of the collection cylinder 4 with screws. Finally, the detection nozzle 3 is inserted into the inner side of the circular ring plate 15. The soft rubber sealing ring 16 is designed on the inner side of the circular ring plate 15. The soft rubber sealing ring 16 seals and wraps the outer surface of the detection nozzle 3, ensuring more comprehensive collection of asphalt and preventing asphalt from splashing to the outside of the collection cylinder 4 during collection. The circular ring plate 15 can be removed later for easy cleaning of the asphalt inside the collection cylinder 4.

[0028] In practice, the outermost nozzle (detection nozzle 3) corresponds to the collection cylinder 4. The collection cylinder 4 is clamped using a designed threaded clamp 8 to ensure that the asphalt sprayed from the detection nozzle 3 is collected more stably inside the collection cylinder 4. The flow rate of all detection nozzles 3 on the asphalt spreader 1 is adjusted to be consistent to ensure uniform spreading. The asphalt spreader 1 travels on the ground 18. During the uniform speed travel of the asphalt spreader 1, all the asphalt sprayed from the detection nozzles 3 is collected by the collection cylinder 4. The asphalt sprayed from the other nozzles is evenly spread on the road surface. The area of ​​the road surface that has not been sprayed with asphalt is calculated, and the amount of unsprayed asphalt in that area is obtained, which is the amount of asphalt collected in the collection cylinder 4. The area of ​​the road surface that has not been sprayed with asphalt is calculated by multiplying the length of the vehicle traveled by the width of the unsprayed road surface. This facilitates the calculation of the amount of asphalt spread. The method for calculating the amount of asphalt spread is a publicly available method and will not be explained in detail here.

[0029] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
