Description

Technical Field

[0001] This utility model relates to the field of highway sampling technology, and in particular to a highway sampling core drilling device. Background Technology

[0002] A road core drill is a specialized piece of equipment used for sampling road surface structures such as highways. It mainly uses a power-driven diamond drill bit to rotate and cut the road surface, thereby obtaining cylindrical core samples of concrete, asphalt, base soil, etc., for subsequent material performance testing and structural quality assessment.

[0003] When using a road core drilling machine, a plastic tube needs to be connected to the machine's water inlet pipe to supply water to the water inlet pipe, thereby cooling the core extraction area of ​​the road surface and reducing dust. However, the connection between the plastic tube and the water inlet pipe is easily loosened under the impact of water pressure, and in severe cases, the plastic tube may even detach from the water inlet pipe, which will make it difficult for the road core drilling machine to operate normally. Utility Model Content

[0004] This utility model proposes a highway sampling core drilling device to solve the problem that the connection between the plastic pipe and the water inlet pipe is easily loosened under the impact of water pressure, and in severe cases, the plastic pipe may even detach from the water inlet pipe, thus hindering the normal operation of the road core drilling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highway sampling core drilling device, comprising a movable frame, sliding rods symmetrically mounted on the top of the movable frame, a movable plate slidably mounted on the outer surfaces of the two sliding rods, a top plate fixedly mounted on one end of the two sliding rods, a threaded rod rotatably mounted on the inner wall of the top plate, an auxiliary plate threadedly connected to the outer surface of the threaded rod, the auxiliary plate fixedly mounted on the bottom of the movable plate, the threaded rod disposed inside the auxiliary plate, a sampling drill cylinder rotatably mounted on one side of the bottom of the auxiliary plate, a motor mounted on one side of the top of the auxiliary plate, the output end of the motor connected to one end of the sampling drill cylinder via a chain belt, a water inlet pipe mounted on the top of the auxiliary plate, the inner wall of the water inlet pipe communicating with the inner wall of the sampling drill cylinder, an auxiliary device provided on the outer surface of the water inlet pipe, the auxiliary device fixing the plastic pipe and the water inlet pipe by setting a rubber ring to abut against the plastic pipe.

[0006] The effect achieved by the above components is as follows: by setting the rubber ring and adjusting the rubber ring, the rubber ring expands in the horizontal direction until the outer surface of the rubber ring abuts against the outer surface of the plastic tube, which can fix the plastic tube and the water inlet pipe, which helps to prevent the plastic tube from detaching from the water inlet pipe and facilitates the normal operation of the road core drilling machine.

[0007] Preferably, the auxiliary device includes an internally threaded cylinder, which is fixedly installed on the top of the auxiliary plate. The water inlet pipe is disposed inside the internally threaded cylinder. A rubber ring is disposed at the bottom of the inner wall of the internally threaded cylinder. The rubber ring has a hollow structure. One side of the rubber ring abuts against the top of the auxiliary plate. An externally threaded cylinder is threadedly connected to the inner wall of the internally threaded cylinder. The externally threaded cylinder is disposed on the other side of the rubber ring. The plastic tube is sleeved on the outer surface of the water inlet pipe.

[0008] The effect achieved by the above components is as follows: when the external threaded cylinder is rotated, it will move on the inner wall of the internal threaded cylinder. When the external threaded cylinder moves, it will squeeze the rubber ring, causing the rubber ring to deform until it is squeezed and comes into contact with the outer surface of the plastic tube. The rubber ring can then provide auxiliary fixation between the plastic tube and the water inlet pipe, which helps to prevent the plastic tube from detaching from the water inlet pipe.

[0009] Preferably, a silicone ring is fixedly installed at one end of the external threaded cylinder, and one side of the silicone ring abuts against one side of the rubber ring.

[0010] The effect achieved by the above-mentioned components is as follows: by setting a silicone ring to replace one end of the external threaded cylinder that abuts against one side of the rubber ring, the rubber ring can be protected to a certain extent when the external threaded cylinder squeezes the rubber ring, which helps to prevent the hollow rubber ring from being damaged due to excessive compression of the rubber ring by the external threaded cylinder.

[0011] Preferably, an auxiliary ring is installed at the top of the inner wall of the external threaded cylinder, and the vertical cross-section of the auxiliary ring is triangular.

[0012] The effect achieved by the above-mentioned components is as follows: by setting a triangular auxiliary ring, the tip of the auxiliary ring abuts against the outer surface of the plastic tube, which can help fix the plastic tube and the water inlet pipe, thereby further preventing the plastic tube from detaching from the water inlet pipe.

[0013] Preferably, an operating ring is fixedly installed on the top of the outer surface of the external threaded cylinder, and the outer surface of the operating ring is provided with protrusions.

[0014] The effect achieved by the above components is as follows: by setting the operating ring, rotating the operating ring can drive the external threaded cylinder to rotate. At the same time, the outer surface of the operating ring is provided with protrusions, which can effectively increase the friction of the outer surface of the operating ring and have an anti-slip effect when rotating the operating ring.

[0015] Preferably, bolts are symmetrically threaded onto the outer surface of the internally threaded cylinder.

[0016] The effect achieved by the above components is as follows: by rotating the bolt, the bolt moves within the inner wall of the internally threaded cylinder until one end of the bolt abuts against the outer surface of the externally threaded cylinder, thus fixing the externally threaded cylinder and the internally threaded cylinder together, which helps to prevent the externally threaded cylinder from loosening within the inner wall of the internally threaded cylinder.

[0017] Preferably, the top of one side of the rubber ring is provided with a bevel.

[0018] The effect achieved by the above-mentioned components is that by setting a bevel at the top of the rubber ring, the distance between the top of the rubber ring and the water inlet pipe can be increased, which makes it easier to fit the plastic tube onto the outer surface of the water inlet pipe.

[0019] Preferably, the inner side of the rubber ring is provided with a plurality of grooves evenly distributed.

[0020] The effect achieved by the above components is that by uniformly setting grooves on the inner wall of the rubber ring, the friction between the rubber ring and the plastic tube can be increased, making the rubber ring more firmly fixed to the plastic tube.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a rubber ring and adjusting the rubber ring, the rubber ring expands in the horizontal direction until the outer surface of the rubber ring abuts against the outer surface of the plastic tube. This fixes the plastic tube and the water inlet pipe, which helps prevent the plastic tube from detaching from the water inlet pipe and facilitates the normal operation of the road core drilling machine.

[0030] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a highway sampling core drilling device, including a movable frame 1. Sliding rods 2 are symmetrically mounted on the top of the movable frame 1. A single movable plate 3 is slidably mounted on the outer surfaces of the two sliding rods 2. A single top plate 4 is fixedly mounted on one end of each sliding rod 2. A threaded rod 5 is rotatably mounted on the inner wall of the top plate 4. An auxiliary plate 6 is threadedly connected to the outer surface of the threaded rod 5. The auxiliary plate 6 is fixedly mounted on the bottom of the movable plate 3. The threaded rod 5 is located inside the auxiliary plate 6. A sampling drill cylinder 7 is rotatably mounted on one side of the bottom of the auxiliary plate 6. A motor 8 is mounted on one side of the top of the auxiliary plate 6. The output end of the motor 8 is connected to the sampling drill cylinder 7 via a chain belt 10. The auxiliary plate 6 is connected to the top of the auxiliary plate 6, and the water inlet pipe 11 is installed on the top of the auxiliary plate 6. The inner wall of the water inlet pipe 11 is connected to the inner wall of the sampling drill barrel 7. The outer surface of the water inlet pipe 11 is provided with an auxiliary device 9. The auxiliary device 9 fixes the plastic pipe and the water inlet pipe 11 by setting a rubber ring 92 to abut against the plastic pipe. By setting the rubber ring 92, the rubber ring 92 can be adjusted so that the rubber ring 92 expands in the horizontal direction until the outer surface of the rubber ring 92 abuts against the outer surface of the plastic pipe. This can fix the plastic pipe and the water inlet pipe 11, which helps to prevent the plastic pipe from detaching from the water inlet pipe 11 and makes it easier for the road core drilling machine to operate normally.

[0031] Reference Figures 2-5As shown, the auxiliary device 9 includes an internally threaded cylinder 91, which is fixedly installed on the top of the auxiliary plate 6. The water inlet pipe 11 is located inside the internally threaded cylinder 91. A rubber ring 92 is provided at the bottom of the inner wall of the internally threaded cylinder 91. The rubber ring 92 is a hollow structure, and one side of the rubber ring 92 abuts against the top of the auxiliary plate 6. An externally threaded cylinder 93 is threadedly connected to the inner wall of the internally threaded cylinder 91 and is located on the other side of the rubber ring 92. A plastic tube is fitted onto the outer surface of the water inlet pipe 11. Rotating the externally threaded cylinder 93 causes it to move along the inner wall of the internally threaded cylinder 91. During this movement, the externally threaded cylinder 93 compresses the rubber ring 92, causing the rubber ring to... When the rubber ring 92 deforms until it is squeezed and comes into contact with the outer surface of the plastic tube, the rubber ring 92 can provide auxiliary fixation between the plastic tube and the water inlet pipe 11, which helps to prevent the plastic tube from detaching from the water inlet pipe 11. A silicone ring 94 is fixedly installed at one end of the external threaded cylinder 93. One side of the silicone ring 94 abuts against one side of the rubber ring 92. By setting the silicone ring 94 instead of one end of the external threaded cylinder 93 abutting against one side of the rubber ring 92, it can play a certain protective role for the rubber ring 92 when the external threaded cylinder 93 squeezes the rubber ring 92, which helps to prevent the hollow rubber ring 92 from being damaged due to excessive squeezing by the external threaded cylinder 93.

[0032] Reference Figures 2-5 As shown, an auxiliary ring 95 is installed on the top of the inner wall of the external threaded cylinder 93. The vertical cross-section of the auxiliary ring 95 is triangular. By setting the triangular auxiliary ring 95, the tip of the auxiliary ring 95 abuts against the outer surface of the plastic tube, which can help fix the plastic tube and the water inlet pipe 11, thereby further preventing the plastic tube from detaching from the water inlet pipe 11. An operating ring 96 is fixedly installed on the top of the outer surface of the external threaded cylinder 93. The outer surface of the operating ring 96 is provided with protrusions. By setting the operating ring 96, rotating the operating ring 96 can drive the external threaded cylinder 93 to rotate. At the same time, the protrusions on the outer surface of the operating ring 96 can effectively increase the friction of the outer surface of the operating ring 96, which has an anti-slip effect when rotating the operating ring 96.

[0033] Reference Figures 2-5 As shown, bolts 97 are symmetrically threaded onto the outer surface of the internally threaded cylinder 91. By rotating the bolts 97, the bolts 97 move within the inner wall of the internally threaded cylinder 91 until one end of the bolts 97 abuts against the outer surface of the externally threaded cylinder 93. This allows the bolts 97 to fix the externally threaded cylinder 93 and the internally threaded cylinder 91, thereby preventing the externally threaded cylinder 93 from loosening within the inner wall of the internally threaded cylinder 91.

[0034] Reference Figure 6As shown, a bevel 98 is provided on the top of one side of the rubber ring 92. By providing the bevel 98 on the top of the rubber ring 92, the distance between the top of the rubber ring 92 and the water inlet pipe 11 can be increased, making it easier to fit the plastic tube onto the outer surface of the water inlet pipe 11. Several grooves are evenly provided on the inner side of the rubber ring 92. By evenly providing the grooves on the inner side of the rubber ring 92, the friction between the rubber ring 92 and the plastic tube can be increased, making the rubber ring 92 more securely fixed to the plastic tube.

[0035] Working principle: Insert the plastic tube into the internal threaded cylinder 93 and auxiliary ring 95, and then fit the plastic tube onto the outer surface of the inlet pipe 11. Rotate the operating ring 96 to drive the external threaded cylinder 93 to rotate. As the external threaded cylinder 93 moves along the inner wall of the internal threaded cylinder 91, it causes the silicone ring 94 to compress the rubber ring 92, causing the rubber ring 92 to expand horizontally until it is compressed and comes into contact with the outer surface of the plastic tube. The rubber ring 92 and auxiliary ring 95 then provide auxiliary fixation between the plastic tube and the inlet pipe 11, helping to prevent the plastic tube from detaching from the inlet pipe 11. Then rotate the bolt 97 to... Bolt 97 moves along the inner wall of the internal threaded cylinder 91 until one end of bolt 97 abuts against the outer surface of the external threaded cylinder 93. Bolt 97 can then fix the external threaded cylinder 93 and the internal threaded cylinder 91, thereby preventing the external threaded cylinder 93 from loosening on the inner wall of the internal threaded cylinder 91. The bevel 98 at the top of the rubber ring 92 can increase the distance between the top of the rubber ring 92 and the water inlet pipe 11, making it easier to fit the plastic tube onto the outer surface of the water inlet pipe 11. At the same time, the groove on the inner side of the rubber ring 92 can increase the friction between the rubber ring 92 and the plastic tube, making the fixation of the rubber ring 92 on the plastic tube more stable.
