However, in actual cutting use, the core sample cannot be rotated during the cutting process, so that the core sample will break and have missing corners at the end of cutting, resulting in an imperfect surface of the core sample after cutting, which affects the next step of detection. For this reason, the present application provides a rotatable cutting machine for concrete core samples. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the core sample cannot be rotated during the cutting process, so that the core sample will break and have chipped corners at the end of cutting, resulting in an imperfect surface of the core sample after cutting, which affects the next step of detection work. The present application provides a rotatable concrete core sample cutting machine.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A rotatable cutting machine for concrete core samples comprises a workbench, the top of the workbench is fixedly connected to a support frame, the interior of the support frame is rotatably connected to a connecting column, a placement groove is provided inside the connecting column, a fastening assembly is installed on one side of the connecting column, one side of the support frame is fixedly connected to a motor 1, the output end of the motor 1 is fixedly connected to one end of the connecting column, a supporting assembly is installed on the top of the workbench, the top of the workbench is slidably connected to a base, the top of the base is fixedly connected to a fixing column, a cutting machine is installed on one side of the fixing column, a cooling assembly is installed on the top of the fixing column, and a collecting assembly is installed inside the workbench.

[0008] By adopting the above technical scheme, the fastening component is started to clamp and fix the core sample placed in the groove. When the core sample is fixed and stable, the motor can be started to drive the core sample inside the connecting column to rotate, so that when the cutting machine is cutting the core sample, the core sample can continue to rotate, so that the last part cut is the center of the core sample, which can avoid the problem of the core sample breaking and missing corners, and prevent the surface of the core sample from being imperfect after cutting, affecting the next step of detection. The cutting machine can then be started to cut the rotating core sample. At the same time, debris will be generated during the cutting process, and the temperature of the cutting tool will continue to rise. At this time, the cooling component can be started to spray water on the cutting surface of the cutting machine and the core sample to cool it down, which greatly improves the service life of the cutting machine and the cutting efficiency. Secondly, the sprayed cooling water is affected by gravity and will fall into the collection component for collection, thereby keeping the workbench clean.

[0010] By adopting the above technical solution, the two-way threaded rod can be rotated by turning the knob, so that the two adjustment plates can be gradually brought closer.

[0021] Furthermore, the collecting assembly comprises a collecting trough provided inside the workbench, a plurality of filter holes are provided through the top of the collecting trough, and a dirt collecting box is slidably connected inside the collecting trough.

[0022] By adopting the above technical solution, as the water flows, sewage and debris will pass through the filter holes into the sewage collecting box in the collection tank, thereby collecting the sewage and debris and effectively improving the overall cleanliness of the workbench.

[0023] In summary, the present application includes at least one of the following beneficial effects:

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a rotatable concrete core sample cutting machine.

[0034] Reference Figure 1 and Figure 4 A rotatable cutting machine for concrete core samples comprises a workbench 1, a support frame 2 is fixedly connected to the top of the workbench 1, a connecting column 3 is rotatably connected inside the support frame 2, a placement slot 31 is provided inside the connecting column 3, a fastening assembly 4 is installed on one side of the connecting column 3, a motor 5 is fixedly connected to one side of the support frame 2, an output end of the motor 5 is fixedly connected to one end of the connecting column 3, a supporting assembly 6 is installed on the top of the workbench 1, a base 7 is slidably connected to the top of the workbench 1, a fixed column 8 is fixedly connected to the top of the base 7, a cutting machine 9 is installed on one side of the fixed column 8, a cooling assembly 10 is installed on the top of the fixed column 8, a collecting assembly 11 is installed inside the workbench 1, a handle 71 is fixedly connected to one side of the base 7, two sliders 72 are symmetrically fixedly connected to the bottom of the base 7, two slide grooves 73 are symmetrically provided on the top of the workbench 1, and the two sliders 72 are slidably connected in the two slide grooves 73 respectively.

[0035] When in use, first insert the core sample to be cut into the placement groove 31, and then start the fastening component 4 to clamp and fix the core sample in the placement groove 31, so that the core sample can remain stable during the cutting process to prevent the core sample from shaking and causing an imperfect cutting surface, which affects the next step of detection. When the core sample is fixed and stable, the motor 5 can be started to drive the connecting column 3 to rotate. When the connecting column 3 rotates, it will drive the core sample inside the placement groove 31 to rotate together. During the rotation of the connecting column 3, the supporting component 6 is used to support and assist the bottom of the connecting column 3, so that when the cutting machine 9 cuts the core sample, the core sample can continue to rotate, so that the last part cut is the center of the core sample, which can avoid the problem of the core sample collapsing and missing corners, and prevent the problem of the core sample collapsing and missing corners after cutting. The surface of the core sample is not perfect, which affects the next step of detection. Then the cutting machine 9 can be started. By pulling the handle 71, the slider 72 at the bottom of the base 7 can be driven to slide inside the slide groove 73 to drive the base 7 to move on the top of the workbench 1. When the base 7 moves, the cutting machine 9 will be driven to move together, so that the rotating core sample can be cut by the moving cutting machine 9. At the same time, debris will be generated during the cutting process, and the temperature of the cutting tool will continue to rise. At this time, the cooling component 10 can be started. The cooling component 10 continuously sprays water to cool the cutting surface of the cutting machine 9 and the core sample, which greatly improves the service life of the cutting machine 9 and the cutting efficiency. Secondly, the sprayed cooling water is affected by gravity and will fall into the collection component 11 for collection, so as to keep the workbench 1 clean.

[0036] Reference Figure 1 and Figure 2The fastening assembly 4 includes a support block 1 41 symmetrically fixedly connected to one side of the connecting column 3, a bidirectional threaded rod 42 is rotatably connected to the opposite surface of the support block 1 41, a knob 43 is fixedly connected to the top of the bidirectional threaded rod 42, two adjustment plates 44 are symmetrically threadedly connected to the bidirectional threaded rod 42, a support block 2 45 is symmetrically fixedly connected to one side of the connecting column 3, a guide rod 46 is fixedly connected to the opposite surface of the support block 2 45, one end of the two adjustment plates 44 away from the bidirectional threaded rod 42 is slidably connected to the guide rod 46, one side of the two adjustment plates 44 is fixedly connected to a clamping plate 47, the clamping surface of the clamping plate 47 is arc-shaped, and an anti-slip pad 48 is fixedly connected to the arc surface.

[0037] When in use, first turn the knob 43 to rotate to drive the bidirectional threaded rod 42 to rotate. When the bidirectional threaded rod 42 rotates, the two adjustment plates 44 will gradually approach according to the guidance of the guide rod 46, thereby driving the two clamping plates 47 to clamp the core sample inside the placement groove 31 stably. At the same time, the anti-slip pad 48 can increase the friction between the clamping plates 47 and the core sample to more stably fix the core sample inside the placement groove 31, so that the core sample can remain stable during the cutting process, preventing the core sample from shaking and causing an imperfect cutting surface, which affects the next step of detection.

[0038] Reference Figure 1 and Figure 3 The support assembly 6 includes a fixed block 61 fixedly connected to the top of the workbench 1. A groove is opened on the top of the fixed block 61. A rotating rod 62 is rotatably connected inside the groove. A roller 63 is fixedly connected to the rotating rod 62. The outer wall of the roller 63 is in contact with the outer wall of the connecting column 3.

[0039] During use, when the motor 5 drives the connecting column 3 to operate, the connecting column 3 will continue to rotate. Because the outer wall of the connecting column 3 fits with the outer wall of the roller 63, when the connecting column 3 continues to rotate, the roller 63 will also rotate in the groove. The roller 63 can support the bottom of the connecting column 3 while assisting the rotation of the connecting column 3, making the rotation of the connecting column 3 smoother.

[0040] Reference Figure 1 and Figure 4 The cooling assembly 10 includes a water tank 101 fixedly connected to the top of the fixed column 8, a pump 102 is fixedly connected to one side of the water tank 101, a bellows 103 is fixedly connected to the output end of the pump 102, and a nozzle 104 is fixedly connected to the end of the bellows 103 away from the pump 102.

[0041] During use, debris will be generated during the cutting process and the temperature of the cutting tool will continue to rise. At this time, the pump 102 can be started to pump out the cooling water inside the water tank 101, and then guided by the bellows 103, the cooling water is sprayed onto the cutting surface of the cutting machine 9 and the core sample through the nozzle 104 to quickly cool down, which greatly improves the service life of the cutting machine 9 and also improves the cutting efficiency.

[0042] Reference Figure 1 and Figure 4 The collecting assembly 11 includes a collecting tank disposed inside the workbench 1 , a plurality of filter holes 111 are formed through the top of the collecting tank, and a dirt collecting box 112 is slidably connected to the collecting tank.

[0043] When in use, the sewage after spraying and the debris generated by cutting will fall on the top of the workbench 1 due to the influence of gravity. As the water flow flushes, the sewage and debris will pass through the filter holes 111 into the sewage collecting box 112 in the collection tank, thereby collecting the sewage and debris, effectively improving the overall cleanliness of the workbench 1.

[0044] The implementation principle of the rotatable concrete core sample cutting machine of the present embodiment is as follows: when in use, first insert the core sample to be cut into the interior of the placement groove 31, and then turn the knob 43 to rotate, so as to drive the bidirectional threaded rod 42 to rotate. When the bidirectional threaded rod 42 rotates, the two adjustment plates 44 will gradually approach according to the guidance of the guide rod 46, thereby driving the two clamping plates 47 to clamp the core sample inside the placement groove 31 stably. At the same time, the friction between the clamping plates 47 and the core sample can be increased by the anti-slip pad 48, so as to fix the core sample more stably inside the placement groove 31, so that the core sample can remain stable during the cutting process, and the core sample can be prevented from shaking, resulting in an imperfect cutting surface, which affects the next step of detection. When the core sample is fixed After stabilization, the motor 5 can be started to drive the connecting column 3 to rotate. When the connecting column 3 rotates, the core sample inside the placement groove 31 will be driven to rotate together. Because the outer wall of the connecting column 3 fits the outer wall of the roller 63, when the connecting column 3 continues to rotate, the roller 63 will rotate in the groove together. The roller 63 can support the bottom of the connecting column 3 while assisting the rotation of the connecting column 3, so that the connecting column 3 rotates more smoothly. In this way, when the cutting machine 9 cuts the core sample, the core sample can continue to rotate, so that the last part cut is the center of the core sample, so as to avoid the problem of the core sample collapsing and missing corners, and prevent the surface of the core sample from being imperfect after cutting, which affects the next step of detection.

[0045] Secondly, the cutting machine 9 can be started to operate, and the slider 72 at the bottom of the base 7 can be driven to slide in the slide groove 73 by pulling the handle 71 to drive the base 7 to move on the top of the workbench 1. When the base 7 moves, the cutting machine 9 will be driven to move together, so that the rotating core sample can be cut by the moving cutting machine 9. At the same time, debris will be generated during the cutting process, and the temperature of the cutting tool will continue to rise. At this time, the pump 102 can be started to operate to extract the cooling water inside the water tank 101, and then the cooling water is sprayed onto the cutting surface of the cutting machine 9 and the core sample through the nozzle 104 through the guidance of the bellows 103 to quickly cool down the temperature, which greatly improves the service life of the cutting machine 9 and the cutting efficiency. Secondly, the sewage after spraying and the debris generated by cutting will fall on the top of the workbench 1 according to the influence of gravity. With the flushing of the water flow, the sewage and debris will pass through the filter hole 111 into the sewage collecting box 112 in the collection tank, so as to collect the sewage and debris, effectively improving the overall cleanliness of the workbench 1.
