Description

TECHNICAL FIELD

[0001] The utility model relates to road surface detection technical field, specifically point road engineering with thickness detection device. BACKGROUND

[0002] Representative points are selected on the road, a core sample is drilled from the road structure layer by a drilling machine, and the thickness of the structure layer is determined by measuring the length of the core sample.

[0003] When the drill bit and the road material (such as asphalt, concrete, etc.) rub against each other, a large amount of heat energy is generated. In order to protect the drill bit and ensure the drilling quality, water needs to be poured onto the drill bit to cool it down when it is working.

[0004] After cooling down during core drilling, the sewage will spread and flow on the road surface, polluting the road surface. Therefore, after each drilling is completed, the sewage on the road surface needs to be cleaned up with a towel or other water-absorbing materials.

[0005] The applicant improves the existing drilling machine to make it more suitable for use in road core drilling. By setting up a special sewage blocking structure, the sewage is limited within a certain area to prevent it from spreading freely. SUMMARY

[0012] The sewage blocking fence is installed on the vertical rod and located below the drilling machine, and the sewage blocking fence surrounds the drill bit and the bottom port is placed on the ground;

[0013] The inner diameter of the sewage blocking fence is greater than the diameter of the drill bit, so that the sewage can be limited in a smaller area, facilitating subsequent cleaning of the sewage.

[0014] Preferred technical solution one: a pressing member is arranged on the bottom frame, the bottom of the pressing member is in contact with the top of the sewage blocking fence, and the pressing member is used to press down the sewage blocking fence.

[0015] The preferred technical solution two: two groups of protrusions are extended forwardly at the left and right sides of the trash barrier in the front part of the chassis, and a group of vertical shafts are fixed at the positions of each group of protrusions close to the trash barrier. The pressing member is composed of a movable handle rotatably installed at the top end of the vertical shaft and a bolt installed in the threaded hole at the other end of the movable handle. A pad is fixed at the bottom end of the threaded hole. When the trash barrier contacts the ground, the pressing member is located on the upper side of the trash barrier for pressing down the trash barrier.

[0016] The preferred technical solution three: a handle is rotatably connected to the vertical shaft at the middle and lower part of the vertical shaft, and the distance between the other end of the handle and the vertical shaft is greater than the distance between the side wall of the trash barrier and the vertical shaft.

[0017] The preferred technical solution four: after the core sampling is completed, the drill bit is moved upward and reset, and the trash barrier held by the handle is just wrapped around the outside of the bottom end of the drill bit.

[0018] The preferred technical solution five: in order to improve the stability of the handle in supporting the trash barrier, a horizontal groove is formed in the middle and lower part of the outer wall of the trash barrier close to the vertical shaft. When the trash barrier is lifted up and the horizontal groove moves to the height of the handle, the end of the handle can be slid into the horizontal groove by rotating the handle. The tail end of the horizontal groove extends upwardly by a vertical groove, and the end of the handle can be clamped into the vertical groove.

[0019] (Three) Technical effects

[0020] The above structure makes the present solution have the following beneficial effects:

[0021] 1. The addition of the trash barrier can effectively intercept the cooling sewage generated during the core sampling process, avoid the sewage from flowing in a large area, and concentrate it in a smaller area, which is convenient for subsequent dipping or removing.

[0022] 2. When not in use, the upwardly moved trash barrier is just wrapped around the side of the drill bit, which can realize the protection of the used drill bit and avoid the collision and damage of the drill bit during transfer.

[0023] 3. The setting of the pressing member and the handle can provide help for efficient interception of sewage during use of the trash barrier and lifting and placing after use. The overall structure is simple, convenient to maintain, and low in modification cost.

[0024] 4. The trash barrier tightly pressed on the ground can also provide strong support for the detection device during use. The frictional resistance between the trash barrier and the road surface can avoid the displacement of the drilling machine during work. BRIEF DESCRIPTION OF DRAWINGS

[0034] When the drilling machine 2 moves downwards to be close to the road surface, the motor is started to drive the drill bit 24 to drill core sampling on the road surface;

[0035] The pollution blocking fence 3 is in a cylindrical structure with an upper and lower opening, is slidably installed on the vertical rod 13 and is located below the drilling machine 2, surrounds the drill bit 24 and is placed on the ground at the bottom end, the pollution blocking fence 3 is sleeved with the annular soft gasket 33 at the bottom side, and the annular soft gasket 33 is preferably made of a material with good toughness and waterproof performance;

[0036] In use, the vehicle frame 1 is parked at a point on the road surface which is previously calibrated, the pollution blocking fence 3 surrounds the point, the annular soft gasket 33 is tightly connected with the road surface, the drilling machine 2 moves downwards to make the drill bit 24 contact the road surface and move into the core, cooling water is added to the direction of the drill bit 24 in the pollution blocking fence, and the water is intercepted in the inner ring of the pollution blocking fence 3, so that the sewage is effectively prevented from spreading everywhere.

[0037] The inner diameter of the pollution blocking fence 3 is greater than the diameter of the drill bit 24, so that the sewage can be limited in a smaller area, after the core is completed, a towel is thrown into the pollution blocking fence 3 or a suction tool is used to clean the sewage, and after the cleaning is completed, the detection device is removed, and the core sample is taken out by a tool for thickness measurement. Embodiment

[0038] On the basis of the embodiment 1, please refer to Figures 3-4 The bottom frame 11 is provided with the pressing member 4, the bottom of the pressing member 4 is in contact with the top of the pollution blocking fence 3, is used for pressing the pollution blocking fence 3 downwards, improves the contact pressure of the annular soft gasket 33 with the road surface, and promotes the interception effect of the sewage;

[0039] Two groups of convex frames 18 are extended forward at the left and right sides of the pollution blocking fence 3 at the front of the bottom frame 11, a group of vertical shafts 19 are fixed at positions close to the pollution blocking fence 3 of each group of convex frames 18, the pressing member 4 is composed of the movable handle 41 rotatably installed at the top end of the vertical shaft 19 and the bolt 42 installed in the threaded hole at the other end of the movable handle 41, and a pad 43 is fixed at the bottom end of the bolt 42 passing through the threaded hole;

[0040] When the trash barrier 3 is in contact with the ground, the pressing part 4 is located on the upper side of the trash barrier 3. At this time, rotating the movable handle 41 makes the end of the movable handle 41, which is provided with a bolt 42, move from the side away from the trash barrier 3 to the top of the trash barrier 3. At this time, the pad plate 43 is located above the top end face of the trash barrier 3. By screwing the bolt 42, the pad plate 43 is lowered to press and contact the top end face of the trash barrier 3, that is, the trash barrier 3 is pressed and forced.

[0041] After the sewage is cleaned, the bolt 42 is screwed to make the pad plate 43 move upward away from the top end face of the trash barrier 3, and then the movable handle 41 is rotated to move the bolt 42 outward away from the top of the trash barrier 3, so as to avoid affecting the subsequent upward movement of the trash barrier 3. Embodiment

[0042] Based on Embodiment 1 or 2, please refer to Figures 3-4 The vertical shaft 19 further has a to handle 5 at the middle and lower part of the vertical shaft 19, and the other end of the to handle 5 is rotatably connected with the vertical shaft 19. The distance between the other end of the to handle 5 and the vertical shaft 19 is greater than the distance between the side wall of the trash barrier 3 and the vertical shaft 19. Therefore, after sampling and sewage discharge are completed, the trash barrier 3 can be lifted to the upper side of the to handle 5 by holding the handle fixed on the trash barrier 3, and then the movable end of the to handle 5 is rotated around the vertical shaft 19 to the lower side of the trash barrier 3. The end of the to handle 5 extending to the lower side of the trash barrier 3 supports the trash barrier 3, so that the trash barrier 3 can be kept away from the ground, and the overall movement of the detection device is facilitated.

[0043] In order to improve the stability of the to handle 5 supporting the trash barrier 3, a horizontal groove 31 can be formed on the outer side wall of the trash barrier 3 near the middle and lower part of the vertical shaft 19. When the trash barrier 3 is lifted to the height of the to handle 5, the end of the to handle 5 can be slid into the horizontal groove 31 by rotating the to handle 5. The tail end of the horizontal groove 31 extends upward by a vertical groove 32. When the to handle 5 slides to the tail end of the horizontal groove 31, the trash barrier 3 moves downward along the to handle 5 under the action of gravity, so that the end of the to handle 5 is clamped into the vertical groove 32. The to handle 5 clamped into the vertical groove 32 cannot be further rotated, which can improve the stability of the to handle 5 supporting the trash barrier 3 and avoid the to handle 5 easily separating from the trash barrier 3 during movement.

[0044] The distance between the vertical groove 32 and the vertical shaft 19 is the minimum distance between the trash barrier 3 and the vertical shaft 19.

[0045] After core sampling is completed, the drill bit 24 is lifted to reset. At this time, the trash barrier 3 supported by the to handle 5 is just around the outside of the bottom end of the drill bit 24, which protects the bottom blade of the drill bit 24.

[0046] The power supply problem of the product can be solved by using a mobile power supply. If a mobile power supply is used for separate power supply, a ground position for placing the mobile power supply is needed, and the mobile power supply needs to be charged in time.

[0047] It is worth mentioning that the drilling machine 2 mentioned in the embodiment, and its matching power supply and control switch can also be provided by the manufacturer, and the circuits and electronic components and modules are all prior art, and those skilled in the art can realize them without further description.

[0048] The undisclosed parts in the utility model are all prior art, and the specific structure and working principle will not be described again.

[0049] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
