Description

Technical Field

[0001] The invention relates to the technical field of coring machines, and in particular to a vehicle-mounted coring machine. Background Art

[0002] After the highway construction is completed, the condition of the highway needs to be inspected. Therefore, it is necessary to use a road coring machine to take samples of the solidified highway, so as to conduct quality inspections on the various layers inside the highway. The coring process is generally divided into two stages: the first step is the drilling stage. In this stage, the coring machine drives the coring drill to rotate. The coring drill is a hollow cylindrical structure. The lower edge of the coring drill is provided with cutting teeth. Through the contact and friction between the cutting teeth and the road surface, the coring drill is drilled vertically into the asphalt pavement; the second step is the coring stage. In this stage, the coring drill is pulled out of the road surface, and then the core sample is taken out of the coring drill. Ordinary coring machines are not convenient to transport. They need to be loaded onto transport vehicles by manpower or small machinery, and the process is relatively cumbersome.

[0003] At the same time, the existing coring machine has two defects: the first is that after the cutting is completed and the drill tube is lifted, the core sample still remains in the road hole and cannot rise synchronously with the drill tube. It is still necessary to manually clamp the core sample with pliers and then take it out, which affects the sampling efficiency; the second is that the core sample can rise synchronously with the drill tube, but the core sample is likely to be stuck inside the drill tube. In order to remove the core sample, the staff usually uses a small hammer to knock on the outer wall of the coring drill. This knocking method will seriously affect the accuracy of the drill tube itself on the one hand, and on the other hand, it will cause the core sample to break during the removal process;

[0004] In the prior art, a patent document with publication number CN108360975B discloses a coring drill and a coring machine suitable for asphalt pavement, and also discloses that the drill body includes a cylindrical liner, and the liner is composed of at least two strip drill pieces with arc-shaped cross-sections. However, the liner of the prior art needs to be assembled and disassembled before and after drilling, which is troublesome to operate. Accordingly, since the drill tube needs to be cooled by water during the drilling process, the sealing of this spliced ​​liner is poor, and water leakage may occur. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] In the present invention, when it is necessary to take out the core sample from the drill barrel, the plug is driven by the adjustment module to rotate 90 degrees, so that the water delivery hole and the water delivery channel are misaligned, thereby achieving the blocking of the water delivery channel. As the water delivery module continues to deliver water into the water delivery cavity, the pressure in the water delivery cavity increases, thereby pushing the sealing disk to move in a direction away from the drill handle, so as to push the core sample in the drill barrel downward for a distance. Finally, it is only necessary to pull the core sample out of the drill barrel, which is very convenient to operate. The present invention does not need to use knocking or disassembly to take out the core sample, and can effectively protect the coring machine and the core sample, thereby improving the accuracy of subsequent core sample detection.

When sampling, the drill tube can be lifted and lowered through the through slot, and there is no need to use lifting equipment to lift the coring machine, so the transportation is more convenient.

[0026] The rotation of the plug in the present invention can not only control the opening or closing of the water conveyance channel, but also after the drilling is completed, before the drill tube rises, the adjusting ring is driven to descend by the lifting part, and the adjusting ring drives the rack to descend in the reserved groove through the adjusting rod, and the rack can drive the plug to rotate in the through hole by cooperating with the gear. During the rotation, the plug can be synchronously translated toward the axial direction of the drill tube until the spiral cone head drills to a certain depth on the surface of the core sample, and then drives the drill tube to rise. The drill tube can stably drive the core sample to rise, so as to avoid the phenomenon that the core sample cannot rise synchronously when the drill tube rises. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figure 1-Figure 4 As shown, the present invention is a vehicle-mounted coring machine, comprising a transport vehicle 1 and a drill barrel 3 fixedly arranged on the transport vehicle 1, a drill shank 302 is fixedly arranged on the drill barrel 3, the drill shank 302 is connected to a rotating module that drives it to rotate, and a plurality of groups of cutting teeth 301 are fixedly arranged in a circumferential direction on one end of the drill barrel 3 away from the drill shank 302; in this embodiment, the cutting teeth 301 are used to follow the drill barrel 3 to perform a circular motion to cut the road surface; specifically, when sampling, the drill shank 302 is driven to rotate by the rotating module, and the drill shank 302 synchronously drives the drill barrel 3 to rotate.

[0042] See also Figure 4-Figure 6 , a plurality of groups of water outlets 306 are arranged in a circumferential array at the bottom of the drill tube 3, each of the water outlets 306 is connected to a water delivery channel 706 arranged on the wall of the drill tube 3, a sealing disc 7 is slidably arranged on the side of the drill handle 302 in the drill tube 3, the outer edge of the sealing disc 7 is slidably fitted with the wall of the tube, and the side of the sealing disc 7 close to the drill handle 302 is connected to the elastic module arranged in the drill tube 3; specifically, eight groups of water outlets 306 are arranged in this embodiment;

[0043] Among them, the sealing disk 7 and the wall of the drill barrel 3 are enclosed to form a water delivery chamber 701, and the water delivery chamber 701 is connected to a water delivery module for delivering water into the chamber, and the end of the water delivery channel 706 away from the water outlet 306 is connected to the water delivery chamber 701 through the water inlet hole 705; in this embodiment, when drilling holes for sampling the road, as the drill barrel 3 rotates, water is delivered to the water delivery chamber 701 through the water delivery module, and the water is delivered to the water delivery channel 706 through the water inlet hole 705, and finally discharged through the water outlet 306, which can simultaneously cool the wall of the drill barrel 3 and the cutting teeth 301.

[0044] Furthermore, each group of water outlets 306 is respectively arranged between two adjacent groups of cutting teeth 301, thereby ensuring that each group of cutting teeth 301 can obtain effective heat dissipation.

[0045] It should be noted that during the normal sampling process, even if the sealing disk 7 is slidably set in the drill barrel 3, based on the setting of the elastic module, when the water supply module delivers water to the water supply chamber 701, the water pressure is not sufficient to drive the elastic module to deform, and the position of the sealing disk 7 in the drill barrel 3 will not change.

[0046] See also Figure 6-Figure 7 The wall of the drill tube 3 is also provided with a plurality of through holes 807 corresponding to the water delivery channel 706, the through holes 807 are perpendicular to the axial direction of the water delivery channel 706, a plug 8 is rotatably arranged in the through hole 807, a water delivery hole 804 for communicating with the water delivery channel 706 is provided on the plug 8, and the plug 8 is connected to an adjustment module for driving the rotation thereof; specifically, in this embodiment, the inner diameter of the through hole 807 is larger than the inner diameter of the water delivery channel 706, and the plug 8 is a cylindrical structure, which is slidably fitted with the inner wall of the through hole 807;

[0047] It can be explained that, during the sampling process, in order to dissipate heat from the drill tube 3 and the cutting teeth 301, the water delivery hole 804 opened on the plug 8 is in a normal communication state with the water delivery channel 706 (see Figure 8 ), water can flow through the water delivery channel 706 and through the water delivery hole 804 to the water outlet 306. After the sampling is completed, when the core sample needs to be taken out of the drill tube 3, the plug 8 is driven by the adjustment module to rotate 90 degrees so that the water delivery hole 804 is misaligned with the water delivery channel 706 (see Fig.10 ), thereby achieving the blocking of the water delivery channel 706. As the water delivery module continues to deliver water to the water delivery chamber 701, the pressure in the water delivery chamber 701 increases, thereby pushing the sealing disk 7 to move in a direction away from the drill handle 302, so as to push the core sample in the drill barrel 3 downward for a distance. Finally, it is only necessary to pull the core sample out of the drill barrel 3, which is very convenient to operate. This embodiment does not require the use of knocking or disassembly to remove the core sample, and can effectively protect the coring machine and the core sample, thereby improving the accuracy of subsequent core sample detection.

[0048] Example 2

[0049] Based on Example 1, please refer to Figure 1 The transport vehicle 1 includes a frame 101, and a plurality of rollers 103 are arranged at the bottom of the frame 101 to drive the frame 101 to move. A trailer hook 102 is fixedly arranged at the front end of the frame 101 for connecting with the traveling vehicle, wherein a through slot 104 is provided at a position corresponding to the drill tube 3 on the frame 101 for lifting and lowering the drill tube 3; it can be explained that in this embodiment, the coring machine only needs to be fixed on the transport vehicle 1. When sampling of the road is required, the frame 101 is connected to the traveling vehicle through the trailer hook 102, and it can be transported to the road to be sampled. When sampling, the drill tube 3 can be lifted and lowered through the through slot 104, and there is no need to use lifting equipment to lift the coring machine, so the transportation is more convenient;

[0050] In this embodiment, the opening diameter of the through slot 104 can be set accordingly based on the diameter of the drill tube 3, and this embodiment is not limited to this.

[0051] See also Figure 3-Figure 5 The water delivery module includes a water delivery cylinder 406 rotatably connected to the drill handle 302. The drill handle 302 is set to a hollow structure, one end of which is connected to the water delivery cavity 701, and the other end is connected to the water delivery cylinder 406. It should be noted that when the rotating module drives the drill handle 302 to rotate, the water delivery cylinder 406 will not rotate synchronously. When the water delivery module delivers water to the water delivery cylinder 406, the water can still be delivered to the water delivery cavity 701 through the inner cavity of the drill handle 302, and the water delivery stability is higher.

[0052] In this embodiment, please refer to Figure 2 , a support frame 2 is fixedly arranged on the frame 101, two groups of limit frames 201 are symmetrically fixedly arranged on the support frame 2, the other end of the limit frame 201 is fixed to the limit plate 203, and a water storage barrel 4 is fixedly arranged on the limit plate 203. The bottom of the water storage barrel 4 is connected to the water pump 402 through a water outlet pipe 401, and the other end of the water pump 402 is connected to the water delivery pipe 404 through a telescopic hose 403, and the other end of the water delivery pipe 404 is connected to the water delivery cylinder 406 through a plurality of groups of branch pipes 405; specifically, the branch pipes 405 of this embodiment are provided with four groups, which can be explained that before sampling, water can be pre-stored in the water storage barrel 4, and when delivering water, the water pump 402 is started, and the water pump 402 first draws out the water in the water storage barrel 4 through the water outlet pipe 401, and then delivers the water to the water delivery pipe 404 through the telescopic hose 403, and finally delivers the water to the water delivery cavity 701 through the branch pipe 405;

[0053] It should be noted that in this embodiment, a liquid level sensor can be set in the water storage barrel 4 to monitor the water level in the barrel in real time. When the water level is insufficient, it can be replenished in time. This part is the existing technology and will not be elaborated on.

[0054] As a further solution of this embodiment, please refer to Figure 2 , guide rods 202 are fixedly arranged on both sides of the supporting base frame 2, the ends of the two groups of guide rods 202 are fixed to the positioning plate 504, and a screw rod 501 is rotatably arranged between the two groups of guide rods 202. A lifting motor 5 is fixedly arranged on the positioning plate 504, and the output end of the lifting motor 5 is fixed to the screw rod 501. A nut 502 is spirally sleeved on the screw rod 501, and the outer side of the nut 502 is fixed to the lifting seat 503. The two ends of the lifting seat 503 are slidably connected with the guide rods 202, and the water pipe 404 is fixed in the lifting seat 503; it can be explained that during the sampling process, the lifting motor 5 is started to drive the screw rod 501 to rotate, and the nut 502 can synchronously drive the lifting seat 503 to descend during the movement of the screw rod 501, and the lifting seat 503 can drive the drill tube 3 to descend through the water pipe 404 to drill the road.

[0055] It should be noted that the lifting motor 5 of the present embodiment can also be replaced by a hand wheel or a handle, and when sampling, the hand wheel or the handle can be manually rotated.

[0056] See also Figure 2 and Figure 3 The rotating module includes a lifting plate 601 fixedly arranged on one side of the lifting seat 503, a servo motor 6 is fixedly arranged on the lifting plate 601, an output end of the servo motor 6 is fixed to a driving wheel 602, a driven wheel 604 is fixedly arranged on the drill handle 302, and the driving wheel 602 and the driven wheel 604 are connected through a belt 603 or a chain transmission; it can be explained that when drilling, the servo motor 6 is started to drive the driving wheel 602 to rotate, the driving wheel 602 drives the driven wheel 604 to rotate through the belt 603 or the chain, and the driven wheel 604 can drive the drill barrel 3 to rotate synchronously through the drill handle 302.

[0057] For further information, see Figure 3 as well as Figure 5-Figure 7The adjustment module includes a reserved groove 801 provided on the wall of the drill tube 3, the reserved groove 801 is arranged on one side of the through hole 807 and is connected, a gear 806 is fixedly arranged at one end of the plug 8 close to the reserved groove 801, a rack 802 is slidably arranged in the reserved groove 801, wherein a plurality of groups of adjustment channels 307 are correspondingly provided in the circumferential direction in the wall of the drill tube 3, the adjustment channels 307 are connected with the reserved groove 801, an adjustment rod 305 is slidably arranged in the adjustment channel 307, one end of each adjustment rod 305 is fixed to the rack 802, and the other end is fixed to the adjustment ring 304, The bottom sides of the driven wheel 604 are respectively provided with lifting parts 303, which are fixed to the adjusting ring 304 to drive the adjusting ring 304 to rise and fall; it can be explained that when the plug 8 needs to be driven to rotate in the through hole 807, the adjusting ring 304 is driven to rise by the lifting part 303, and the adjusting ring 304 drives the rack 802 to rise in the reserved groove 801 through the adjusting rod 305, and the rack 802 can drive the plug 8 to rotate in the through hole 807 by cooperating with the gear 806, so as to realize the opening and closing of the water delivery channel 706 (see Fig.10 ).

[0058] In addition, the lifting part 303 in this embodiment can adopt an electric cylinder or a hydraulic cylinder to drive the adjustment ring 304 to move up and down in the vertical direction, and this embodiment is not limited to this.

[0059] When the drilling is completed, in order to ensure that the core sample can rise synchronously with the drill tube 3, in this embodiment, refer to Figure 5-Figure 7 , an external thread 805 is provided on the side of the plug 8 close to the reserved groove 801, and an internal thread is provided on the groove wall of the reserved groove 801 close to the water delivery channel 706. The plug 8 is spirally connected to the groove wall through the external thread 805 and the internal thread, wherein a spiral cone head 803 is fixedly arranged on the end of the plug 8 away from the gear 806; it can be explained that after the drilling is completed, before the drill tube 3 rises, the lifting part 303 drives the adjusting ring 304 to descend, and the adjusting ring 304 drives the rack 802 to descend in the reserved groove 801 through the adjusting rod 305, and the rack 802 can drive the plug 8 to rotate in the through hole 807 by cooperating with the gear 806. During the rotation process, the plug 8 can be synchronously translated toward the axial direction of the drill tube 3 until the spiral cone head 803 drills to a certain depth on the surface of the core sample (see Fig. 9 ), and then drive the drill tube 3 to rise, and the drill tube 3 can stably drive the core sample to rise.

[0060] It should be noted that, when the plug 8 rotates to block the water supply channel 706, the plug 8 will translate a distance in the direction away from the axis of the drill tube 3. Therefore, in this embodiment, the width of the rack 802 needs to be smaller than the axial length of the gear 806 to avoid interference between the plug 8 and the rack 802. Accordingly, when the plug 8 translates, its spiral cone head 803 will not move to the water supply channel 706 to avoid water leakage from the gap of the spiral cone head 803. In this embodiment, the axial length of the plug 8 can be set accordingly based on its translation distance.

[0061] See also Figure 3-Figure 4 The elastic module includes a telescopic rod 702 fixed to the sealing disk 7, a sleeve 704 slidably plugged with the telescopic rod 702 is rotatably arranged in the water delivery cylinder 406, and a telescopic spring 703 is provided on the telescopic rod 702; specifically, one end of the telescopic spring 703 is fixed to the sealing disk 7, and the other end is fixed to the sleeve 704; it can be explained that when the sealing disk 7 descends, the telescopic rod 702 can be synchronously driven to move, so as to drive the telescopic spring 703 to stretch and generate elastic force, which is used for subsequently driving the sealing disk 7 to reset.

See Figure 5-Figure 7After the sampling is completed, the lifting part 303 drives the adjusting ring 304 to descend, and the adjusting ring 304 drives the rack 802 to descend in the reserved groove 801 through the adjusting rod 305. The rack 802 drives the plug 8 to rotate in the through hole 807 by cooperating with the gear 806. The plug 8 moves horizontally toward the axis of the drill tube 3 until the spiral cone head 803 drills to a certain depth on the surface of the core sample (see Fig. 9 );

[0068] S6, the movable drill tube 3 rises, and after the drill tube 3 drives the core sample to rise to a preset height, the lifting part 303 drives the rack 802 to reset, and each spiral cone head 803 is separated from the core sample;

[0069] S7, the section module drives the plug 8 to rotate 90 degrees (refer to Fig.10 ), so that the water delivery hole 804 and the water delivery channel 706 are offset and sealed. As the water delivery module continues to deliver water into the water delivery chamber 701, the pressure in the water delivery chamber 701 increases, pushing the sealing disk 7 to move in a direction away from the drill handle 302, so as to push the core sample in the drill barrel 3 downward for a distance, and then pull the core sample out.
