Description

Technical Field

[0001] This utility model relates to the field of core drilling machines, and in particular to a concrete core drilling machine. Background Technology

[0002] Concrete refers to cement concrete, which is made by mixing cement as a binder, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. After the concrete is poured and cured to meet the standards for obtaining core samples, a core drilling machine is used to drill holes and take samples. However, current core drilling machines generate a lot of dust when drilling concrete. The dust is scattered and affects the on-site construction environment. Long-term inhalation of dust can also cause great harm to the health of workers. In addition, after drilling the concrete, the concrete sample is easy to get stuck in the drill barrel and is not easy to remove. Workers need to manually use tools to knock the drill barrel, which is a cumbersome process and increases the workload of workers. Utility Model Content

[0003] This utility model discloses a concrete core drilling machine, which solves the problems of dust being randomly scattered during concrete drilling and sampling, affecting the on-site construction environment, and concrete samples being easily stuck in the drill barrel and difficult to remove.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A concrete core drilling machine includes a mobile vehicle with a fixed frame fixed on it. A lifting plate is mounted on the fixed frame, and a connecting frame is fixed to the bottom of the lifting plate. A vertical cylinder passes through the bottom of the connecting frame, and a drill cylinder is connected to the bottom of the vertical cylinder. A first motor for driving the vertical cylinder to rotate is fixed on the connecting frame. A cover is slidably connected to the outer side of the connecting frame, and the cover can cover the drill cylinder after sliding downward. A support frame is fixed on the lifting plate, and a first electric telescopic rod for driving the support frame to rise and fall is mounted on the fixed frame. A vertical rod passes through the lifting plate on the inner side of the support frame, and a second electric telescopic rod is mounted on the support frame for driving the vertical rod to move downward into the drill cylinder.

[0005] Compared with the prior art, the present invention has the following beneficial effects: After the mobile vehicle moves to the designated position, the first electric telescopic rod drives the drill cylinder downwards, bringing the bottom of the drill cylinder into contact with the concrete drilling sampling area. Simultaneously, the bottom of the cover contacts the concrete, and the cover, in conjunction with the connecting frame, seals the drill cylinder. As the first motor drives the drill cylinder to rotate and begin drilling for concrete sampling, the telescopic end of the first electric telescopic rod continuously drives the drill cylinder downwards. Because the cover and connecting frame are slidably connected, the cover remains stationary as the connecting frame moves downwards, ensuring a continuous seal on the concrete drilling sampling area. Once the concrete sampling is complete, the drill cylinder moves the concrete sample upwards, and the telescopic end of the second electric telescopic rod drives the vertical rod downwards into the drill cylinder, facilitating the ejection of the concrete sample. This invention seals the concrete drilling sampling area, preventing dust from scattering, and allows for the rapid and effective ejection of the concrete sample from the drill cylinder, reducing the workload of workers.

[0008] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0009] like Figure 1 and Figure 2As shown, this utility model provides a concrete core drilling machine, including a mobile vehicle 1, a fixed frame 2 fixed on the mobile vehicle 1, a lifting plate 21 on the fixed frame 2, a connecting frame 22 fixed at the bottom of the lifting plate 21, a vertical cylinder 3 penetrating through the bottom of the connecting frame 22, and a drill cylinder 31 connected to the bottom of the vertical cylinder 3. A first motor 23 for driving the vertical cylinder 3 to rotate is fixed on the connecting frame 22. A cover 4 is slidably connected to the outside of the connecting frame 22. After the cover 4 slides downward, it can cover the drill cylinder 31. A support frame 7 is fixed on the lifting plate 21. A first electric telescopic rod 27 for driving the support frame 7 to rise and fall is provided on the fixed frame 2. A vertical rod 71 penetrating the lifting plate 21 is provided on the inside of the support frame 7. A second electric telescopic rod 72 for driving the vertical rod 71 to move downward into the drill cylinder 31 is provided on the support frame 7. A fixed housing 41 is fixed inside the casing 4, and a nozzle is connected to the side of the fixed housing 41 facing the drill barrel 31. A water tank 5 is fixed on the mobile vehicle 1, and a water pump 51 is installed on the water tank 5. The drain end of the water pump 51 is connected to a first flexible hose 52 that is connected to the fixed housing 41. A connecting housing 73 is fixed to the telescopic end of the second electric telescopic rod 72. The vertical rod 71 is hollow and open at both ends. The connecting housing 73 is connected to the top end of the vertical rod 71. There are two water pumps 51 on the water tank 5, and a second flexible hose 6 connected to the drain end of one of the water pumps 51 is connected to the connecting housing 73.

[0010] The lifting plate 21 is slidably connected to the fixed frame 2, which is U-shaped. The fixed end of the first electric telescopic rod 27 passes through the top of the fixed frame 2 and is connected to it. The fixed end of the second electric telescopic rod 72 passes through the top of the support frame 7 and is fixed to it. The fixed frame 2 has a hole through which the fixed end of the second electric telescopic rod 72 passes. The moving vehicle 1 has an opening through which the cover 4 passes. After the moving vehicle 1 is moved to the designated position, the telescopic end of the first electric telescopic rod 27 drives the support frame 7 to move downward. The support frame 7 then drives the connecting frame 22 to move downward through the lifting plate 21. The connecting frame 22 then drives the drill cylinder 31 to move downward through the vertical cylinder 3, so that the drill cylinder 31 contacts the sampling point of the concrete. The cover 4 also contacts the concrete. When the first motor 23 drives the drill cylinder 31 to rotate, in conjunction with the continuous downward movement of the drill cylinder 31, the drilling can be opened. The concrete sampling operation begins. The casing 4 covers the drill barrel 31, effectively preventing dust generated during drilling from spreading everywhere. Since the casing 4 and the connecting frame 22 are slidably connected, the casing 4 always covers and seals the drilled part of the concrete as the drill barrel 31 and the connecting frame 22 continue to move downward. A water pump 51 drains water from the water tank 5 into the fixed casing 41 through the first hose 52. The water in the fixed casing 41 is then discharged through the nozzle, allowing the water to come into contact with the drill barrel 31. This cools the drill barrel 31 and further prevents dust, allowing the drill barrel 31 to better sample the concrete. There are two fixed casings 41, arranged left and right. Each fixed casing 41 has a set of nozzles, and there are two corresponding first hoses 52. Each of the two first hoses 52 is connected to the drain end of a water pump 51. Alternatively, depending on the actual situation, another water pump 51 can be started to discharge water through the second hose 6 into the connecting shell 73, allowing the water to enter the vertical rod 71. At the same time, the bottom end of the vertical rod 71 is inserted into the vertical cylinder 3. After the water is discharged into the interior of the drill barrel 31, it can also cool the drill barrel 31 and prevent dust. The staff can start both water pumps 51 at the same time or select one to start, depending on the actual situation of the on-site construction. After the concrete sampling is completed, the drill cylinder 31 is moved upward to return to its original position. Then, the telescopic end of the second electric telescopic rod 72 drives the vertical rod 71 through the connecting shell 73 to pass through the vertical cylinder 3 and enter the drill cylinder 31, which can push out the concrete sample inside the drill cylinder 31.

[0011] like Figure 1 and Figure 4As shown, a moving plate 8 is slidably connected to the top of the moving vehicle 1. A second motor 81 is fixed on the moving plate 8, and a lead screw 82 is fixed on the shaft of the second motor 81. A moving frame 83, which is slidably connected to the moving plate 8, is threaded onto the lead screw 82. A collection cylinder 84 passes through the top of the moving frame 83. A third electric telescopic rod 9 is fixed on the moving vehicle 1 to drive the moving plate 8 to move back and forth so that the collection cylinder 84 is located directly below the drill barrel 31. A fixing ring 85 is fixed on the collection cylinder 84, the bottom of which contacts the top of the moving frame 83. A sponge cylinder 86 is fixed inside the collection cylinder 84. The moving frame 83 is L-shaped and has a set of collection cylinders 84. When the drill barrel 31 has finished sampling and moved upward, the third electric telescopic rod 9 is first activated to drive the moving plate 8 to move towards the fixed frame 2 (moving forward, so that...). Figure 1 (As shown in the diagram), the movable plate 8 has a notch on the side near the fixed frame 2 that corresponds to a vertical part of the fixed frame 2, allowing the movable plate 8 to move directly below the drill barrel 31; then, the second motor 81 (which is a servo motor) can be started to rotate the lead screw 82, causing the movable frame 83 to move towards the drill barrel 31, so that a collection cylinder 84 is located directly below the drill barrel 31. Then, the telescopic end of the first electric telescopic rod 27 drives the drill barrel 31 to move downwards, causing the drill barrel 31 to enter the collection cylinder 84. Subsequently, the first electric telescopic rod 27... The telescopic end of the first electric telescopic rod drives the drill barrel 31 to move upward. At this time, the telescopic end of the second electric telescopic rod 72 drives the vertical rod 71 to move downward and enter the drill barrel 31, pushing out the concrete sample so that the concrete sample can be stored in the collection barrel 84. The sponge tube 86 inside the collection barrel 84 can effectively protect the concrete sample and prevent the concrete sample from colliding with the inner wall of the collection barrel 84. The fixing ring 85 can place the collection barrel 84 in the round hole opened at the top of the moving frame 83. Afterward, the staff can directly transfer the collection barrel 84 to the designated position.

[0012] like Figure 1 , Figure 2 and Figure 3As shown, an electromagnet 26 is fixed to the bottom of the lifting plate 21, which contacts the top of the cover 4. The cover 4 is made of magnetic material; a set of rubber blocks 42 is fixed to the bottom of the cover 4. A first pulley 24 and a second pulley 32 are fixed to the shaft of the first motor 23 and the vertical cylinder 3, respectively. A belt 25 is provided on the inner side of the connecting frame 22, and the first pulley 24 and the second pulley 32 are connected by the belt 25. A control panel 11 and a handle 12 are fixed on the mobile vehicle 1. The mobile vehicle 1 is equipped with a battery (not shown in the figure), which can supply power to the first electric telescopic rod 27, the second electric telescopic rod 72, the third electric telescopic rod 9, the first motor 23, the second motor 81, the water pump 51, and the electromagnet 26. The control panel 11 can control the opening and closing of the first electric telescopic rod 27, the second electric telescopic rod 72, the third electric telescopic rod 9, the first motor 23, the second motor 81, the water pump 51, and the electromagnet 26 after setting the control program (the setting of the control program is a very mature existing technology, which will not be described in detail here). There are two third electric telescopic rods 9, and the two third electric telescopic rods 9 operate synchronously in a closed-loop position synchronization manner. After the first motor 23 is started, it can drive the belt 25 through the first pulley 24 to rotate the second pulley 32, so that the vertical cylinder 3 can drive the drill barrel 31 to start rotating.
