Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, specifically, it relates to an asphalt surface core sampling and pollution prevention device. Background Technology

[0002] In the quality inspection of asphalt pavement in road engineering, coring is widely used because it can directly obtain key parameters such as compaction degree, thickness, and interlayer bonding state. However, the high temperature generated by the high-speed rotation of the sampling drill bit during traditional coring requires water cooling, which leads to the splashing of mud containing asphalt debris, polluting the road surface and affecting traffic and environmental hygiene.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN221764920U discloses an asphalt surface coring pollution prevention device. This device connects a drain branch pipe to a liquid-filling tray via a connecting sleeve. During use, it utilizes gravity to divert cooling water and mud into a container for centralized treatment, thus preventing mud containing asphalt debris from splashing and polluting the road surface. However, this device still has the following problems during use: asphalt particles and aggregate debris in the mud easily deposit on the inner wall of the drain branch pipe, especially at low temperatures where asphalt adhesion increases, causing the pipe's flow cross-section to gradually shrink. If not cleaned in time, this may lead to a decrease in drainage efficiency or even complete blockage, causing liquid pressure buildup inside the sleeve, affecting the cooling effect of the sampling drill bit and increasing the risk of mud overflow. Simultaneously, frequent manual cleaning or replacement of the drain pipe (requiring machine shutdown for disassembly) reduces testing efficiency, especially prominent in continuous highway testing operations.

[0004] Based on this, the present invention provides a novel anti-pollution device for core sampling of asphalt surface layers to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main objective of this utility model is to provide an anti-pollution device for asphalt surface coring, so as to solve the problems of high risk of blockage of drainage branch pipe and high maintenance cost of traditional asphalt surface coring anti-pollution devices.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A pollution prevention device for asphalt surface core sampling includes:

[0008] A splash guard is installed on the upper side of the support plate and directly above the movable hole of the support plate. An inclined drain pipe is provided on one side of the splash guard and a drainage mechanism is provided on the other side.

[0009] The support plate has a closed pad at the bottom, and both the support plate and the closed pad have through holes that match the splash guard.

[0010] The liquid receiving tray is located on one side of the support plate and below the drain pipe.

[0011] In a preferred embodiment, the unblocking mechanism includes an unblocking rod, one end of which matches a through hole provided on one side of the splash guard, and the other end is connected to a mounting rod, and a connecting seat is also provided at the other end of the mounting rod.

[0012] In a preferred embodiment, the drain rod is inclinedly disposed on the outside of the splash guard and slidably connected to a through hole disposed on the splash guard, and the outer diameter of the drain rod is the same as the inner diameter of the drain pipe.

[0013] In a preferred embodiment, a first mounting plate and a second mounting plate are further provided above the support plate. The first mounting plate has an inclined guide groove, and a guide rod is slidably connected in the guide groove. The guide rod is connected to the mounting rod. The second mounting plate has an inclined connecting groove on one side, and the connecting seat is slidably connected to the connecting groove.

[0014] In a preferred embodiment, the first mounting plate and the second mounting plate are arranged symmetrically.

[0015] In a preferred embodiment, a movable groove is provided on one side of the connecting seat, and a limiting block is slidably connected in the movable groove, the limiting block matching the limiting slot opening on the connecting groove.

[0016] In a preferred embodiment, a spring is also provided in the inner wall of one side of the movable groove, and one end of the spring is connected to the outer wall of one side of the limiting block.

[0017] In a preferred embodiment, a movable opening is provided on one side of the connecting seat, and a connecting plate is slidably disposed within the movable opening.

[0018] In a preferred embodiment, the connecting plate is disposed on one outer wall of the limiting block.

[0019] In a preferred embodiment, the second mounting plate is provided with a limiting hole that matches a limiting block.

[0020] Compared with the prior art, this utility model provides a device for preventing pollution during core sampling of asphalt surface layers, which has the following beneficial effects:

[0021] 1. The splash guard ensures that the wastewater generated during the coring process is collected inside the splash guard and discharged into the receiving tray through the drain pipe, preventing the wastewater from flowing onto the road surface outside the splash guard and achieving the effect of pollution prevention.

[0022] 2. Through the design of the unblocking mechanism, after core sampling is completed, the connecting seat is moved. This, along with the guide groove and guide rod, allows the connecting seat to move the mounting rod, which in turn moves the unblocking rod until it reaches the inside of the drain pipe and moves along its inner wall. This unblocks the drain pipe, preventing blockages during drainage. This solves the problems of high risk of blockage in the drain branch pipe and high maintenance costs associated with traditional asphalt surface core sampling and pollution prevention devices.

[0039] As per the instruction manual Figures 1-8 As shown, this utility model provides a technical solution:

[0040] A pollution prevention device for asphalt surface coring includes a splash guard 1, a support plate 2, and a drip tray 3; wherein:

[0041] The splash guard 1 is installed on the upper side of the support plate 2 and is located directly above the movable hole of the support plate 2. An inclined drain pipe 4 is also fixedly installed on one side of the splash guard 1, and a dredging mechanism is provided on the other side.

[0042] The bottom of the support plate 2 is fixedly installed with a sealing pad 12, and both the support plate 2 and the sealing pad 12 are provided with through-holes that match the splash-proof cylinder 1.

[0043] The liquid receiving tray 3 is located on one side of the support plate 2 and below the drain pipe 4.

[0044] In the above description, the diameter of the movable hole is slightly larger than the diameter of the splash guard 1, which facilitates the embedding and fixing of the splash guard 1. In use, the support plate 2 is placed at the road surface core sampling position through the sealing pad 12 (used to enhance friction and ensure the stability of the support plate 2 during use). After it is placed firmly, the sampling drill bit is inserted into the splash guard 1 to core the road surface. The wastewater generated during the core sampling process collects in the splash guard 1 and is discharged into the receiving tray 3 through the drain pipe 4, so that the wastewater will not flow onto the road surface outside the splash guard 1, thus achieving the effect of pollution prevention.

[0045] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the unblocking mechanism includes an unblocking rod 13. One end of the unblocking rod 13 matches a through hole provided on one side of the splash guard 1, and the other end is connected to the mounting rod 7. The other end of the mounting rod 7 is also fixedly connected to a connecting seat 9.

[0046] In the above description, during use, the connecting seat 9 can drive the mounting rod 7 to move, and the mounting rod 7 drives the unblocking rod 13 to move until the unblocking rod 13 moves to the inside of the drain pipe 4 and moves along the inner wall of the drain pipe 4, thereby unblocking the drain pipe 4 and preventing the drain pipe 4 from becoming blocked during use.

[0047] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the unblocking rod 13 is inclinedly arranged on the outside of the splash guard 1 and slidably connected to the through hole provided on the splash guard 1. The position of the through hole corresponds to the position of the drain pipe 4, and the outer diameter of the unblocking rod 13 is the same as the inner diameter of the drain pipe 4.

[0048] In the above description, the inclined setting of the unblocking rod 13 and the structural arrangement of the unblocking rod 13 and the drain pipe 4 make it easy for the unblocking rod 13 to move in the drain pipe 4 during use, so as to unblock the drain pipe 4.

[0049] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first mounting plate 5 and a second mounting plate 6 are symmetrically arranged above the support plate 2. An inclined guide groove 10 is provided on the first mounting plate 5. A guide rod 11 is slidably connected in the guide groove 10. The end of the guide rod 11 is fixedly connected to the outer wall of one side of the mounting rod 7. An inclined connecting groove 8 is provided on one side of the second mounting plate 6. The connecting seat 9 is slidably connected in the connecting groove 8.

[0050] As described above, the mounting rod 7 can be installed at an angle by setting the first mounting plate 5 and the second mounting plate 6, and the position of the connecting groove 8 and the guide groove 10 can be used to facilitate the adjustment of the connecting seat 9 between the first mounting plate 5 and the second mounting plate 6.

[0051] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, a movable groove 14 is provided on one side of the connecting seat 9, and a limiting block 15 is slidably connected in the movable groove 14. The limiting block 15 matches the limiting slot 16 opened on the connecting groove 8. A spring 17 is also installed in the inner wall of one side of the movable groove 14, and one end of the spring 17 is connected to the outer wall of one side of the limiting block 15. A movable opening 18 is also provided on one side of the connecting seat 9, and a connecting plate 19 is slidably arranged in the movable opening 18. The connecting plate 19 is fixedly connected to the outer wall of one side of the limiting block 15.

[0052] In the above description, after the core sampling is completed, the sampling drill bit is removed from the splash guard 1, and then the connecting plate 19 is pulled to move. The connecting plate 19 drives the limiting block 15 to move, so that the limiting block 15 moves out of the limiting slot 16. After the limiting block 15 moves out of the limiting slot 16, the connecting seat 9 is pushed to move through the connecting groove 8. With the help of the guide groove 10 and the guide rod 11, the connecting seat 9 can drive the mounting rod 7 to move. The mounting rod 7 drives the unblocking rod 13 to move until the unblocking rod 13 moves to the inside of the drain pipe 4 and moves along the inner wall of the drain pipe 4, thereby unblocking the drain pipe 4.

[0053] Specifically, such as Figure 8 As shown, due to the setting of spring 17, when spring 17 is in normal state, the limiting block 15 can pass through the limiting hole on the second mounting plate 6, which plays the role of limiting the position of the connecting seat 9.

[0054] The implementation principle of the asphalt surface coring and pollution prevention device described in this embodiment is as follows:

[0055] In practical use, the support plate 2 is placed at the road surface core sampling location via the sealing pad 12. After it is placed securely, the sampling drill bit 20 is inserted into the splash guard 1 to perform core sampling on the road surface. Wastewater generated during the core sampling process collects inside the splash guard 1 and is discharged into the receiving tray 3 through the drain pipe 4, preventing wastewater from flowing onto the road surface outside the splash guard 1. This solves the problem of wastewater flowing onto the road surface and causing pollution when core sampling is performed on the asphalt surface layer 21, achieving a pollution prevention effect. After the core sampling is completed, the sampling drill bit is removed from the splash guard 1, and then the connecting plate 19 is pulled to move it. When the connecting plate 19 moves, it drives the limiting block 15 to move, so that the limiting block 15 moves out of the limiting slot 16. After the limiting block 15 moves out of the limiting slot 16, it pushes the connecting seat 9 to move through the connecting groove 8. With the help of the guide groove 10 and guide rod 11, the connecting seat 9 can drive the mounting rod 7 to move. The mounting rod 7 drives the unblocking rod 13 to move until the unblocking rod 13 moves to the inside of the drain pipe 4 and moves along the inner wall of the drain pipe 4, thereby unblocking the drain pipe 4 and preventing blockage during drainage.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
