Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a rotating device of a concrete core cutting machine. Background Art

[0002] Concrete refers to a product made by mixing cement as a binder, sand and stone as aggregates, with water and admixtures in a certain proportion. Concrete core samples are often used to test the quality of concrete. Before testing the quality of concrete, it is necessary to cut it and then conduct relevant mechanical experiments. The strength of the concrete can be inferred based on the various indicators of the core sample to ensure the safety and durability of the concrete structure.

[0003] A concrete core sample cutting machine mentioned in an existing Chinese public patent (authorization announcement number: CN220313801U) can start a water pump to pump out cooling water in a water tank and spray it onto a blade through a water nozzle to cool the blade. This makes it less likely for the blade to crack due to overheating when cutting the core sample, thereby improving the safety of the cutting work. At the same time, the powder in the cutting process is easily mixed with the cooling water to produce cooling wastewater. The sprayed cooling water has a certain effect of suppressing powder splashing, thereby improving the working environment.

[0004] In the existing method of cutting a concrete core sample, the core sample is first placed on a clamping block and then cut with a cutting knife. However, since the cutting of the concrete core sample is often done from one side to the other, the concrete core sample is subjected to excessive impact force at the end of the cutting, which may cause the concrete core sample to have a missing corner, resulting in an imperfect surface of the concrete core sample after cutting, thus affecting the next step of detection. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the cutting of concrete core samples is often done from one side to the other, and the concrete core samples are subjected to excessive impact force at the end of cutting, which may cause the concrete core samples to be chipped. The present application provides a rotating device for a concrete core sample cutting machine.

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

[0007] The cam is connected with the cutting tool by the adjusting base, and the cam is connected with the cutting tool at the bottom of the cutting box to drive the cutting tool to move the cutting tool to the cutting position.

Then, the cutting device is started so that the cutting device cuts the rotating core sample body downward, and the risk of missing corners caused by cutting from one side to the other side can be reduced by slowly cutting the cutting knife into the inside of the core sample body. The stability between the vertical plate and the core sample body can be improved by the connecting mechanism, and the cutting of core samples of different lengths can be facilitated by the adjustment mechanism.

[0009] Furthermore, the adjustment mechanism includes adjustment blocks fixedly connected to both sides of the top of the base plate, a sliding groove is provided inside the adjustment block, a sliding block is slidably connected inside the sliding groove, and the top of one side of the sliding block is fixedly connected to the mounting seat.

[0010] By adopting the above technical solution, one side of the sliding block is pulled to move inside the sliding groove, and the movement of the sliding block drives the mounting seat to move.

By adjusting the position of the sliding block inside the sliding groove, the position of the vertical plate can be freely adjusted according to the different lengths of the core sample body.

[0011] Furthermore, a connecting block is fixedly connected to the top of the sliding block on the other side, and a surface of the connecting block close to the cutting box is rotatably connected to the driving rod.

[0013] Furthermore, a limiting hole is provided on one side of the adjusting block, a fastener is fixedly connected to one side of the sliding block, the fastener is composed of a spring and a telescopic rod, and the fastener is slidably connected to the limiting hole.

[0014] By adopting the above technical solution, the position of the sliding block can be fixed by the fastener, so that the sliding block remains stable during operation.

[0015] Furthermore, the connecting mechanism includes a horizontal plate 2 fixedly connected to one side of the vertical plate, the top of the horizontal plate 2 is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a handle, the bottom end of the threaded rod passes through the horizontal plate 2 and is rotatably connected to a clamping plate, and the clamping plate contacts the core sample body when moving.

[0016] By adopting the above technical solution, the handle is rotated to drive the clamping plate downward to clamp and fix the core sample body, thereby improving the stability between the vertical plate and the core sample body.

[0017] Furthermore, a clamping groove is provided on one side of the clamping plate close to the core sample body, and the clamping groove is arranged in an arc shape.

[0018] By adopting the above technical solution, the clamping plate can fit the core sample more closely, thereby increasing the clamping area of ​​the clamping plate.

[0019] Furthermore, a rubber pad is fixedly connected to one side of the clamping groove close to the core sample body, and the rubber pad is adapted to the shape of the clamping groove.

[0020] By adopting the above technical solution, the rubber pad can increase the friction between the clamping plate and the core sample body.

[0021] Furthermore, an auxiliary rod is fixedly connected to the top of the clamping plate, the top end of the auxiliary rod passes through the second transverse plate, and the auxiliary rod is slidably connected to the second transverse plate.

[0022] By adopting the above technical solution, the auxiliary rod provides an additional supporting point for the clamping plate, so that the clamping plate remains stable when moving.

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

[0035] When cutting the concrete core sample, first place the core sample body 5 on the placement seat 4, then move the driving rods 3 on both sides so that the two ends of the core sample body 5 are placed on the horizontal plate 11, so that the vertical plates 10 on both sides are in contact with the two ends of the core sample body 5, then start the rotating motor 2 to drive the driving rod 3 to rotate, and the vertical plates 10 are driven to rotate by the rotation of the driving rod 3, and the vertical plates 10 are driven to rotate the core sample body 5 on the top of the placement seat 4, and then start the cutting device 9 so that the cutting device 9 cuts the rotating core sample body 5 downward, and the cutting knife slowly moves towards the core sample Internal cutting of the main body 5 can reduce the risk of chipping caused by cutting from one side to the other, making the incision smoother and continuous, less prone to chipping or cracks, and facilitating subsequent inspection work. At the same time, the rotation direction of the core sample body 5 is opposite to the rotation direction of the cutting device 9, so that the core sample body 5 can be cut off faster, thereby improving the cutting efficiency of concrete slices. The adjustment mechanism facilitates the cutting of core sample bodies 5 of different lengths, and the connecting mechanism can improve the stability between the vertical plate 10 and the core sample body 5 to ensure the normal rotation of the core sample body 5.

[0036] Reference Figures 1 to 3 The adjustment mechanism includes an adjustment block 18 fixedly connected to both sides of the top of the bottom plate 8, a sliding groove 19 is opened inside the adjustment block 18, a sliding block 20 is slidably connected inside the sliding groove 19, and the top of one side of the sliding block 20 is fixedly connected to the mounting seat 1.

[0037] A connecting block 23 is fixedly connected to the top of the sliding block 20 on the other side, and a surface of the connecting block 23 close to the cutting box 6 is rotatably connected to the driving rod 3 .

[0038] In addition, a limiting hole 21 is provided on one side of the adjusting block 18 , and a fastener 22 is fixedly connected to one side of the sliding block 20 . The fastener 22 is composed of a spring and a telescopic rod, and the fastener 22 is slidably connected to the limiting hole 21 .

[0039] When cutting core sample bodies 5 of different lengths, by pulling one side sliding block 20 to move inside the sliding groove 19, the sliding block 20 moves to drive the mounting seat 1 to move, and the mounting seat 1 moves to make the driving rod 3 move inside the cutting box 6, so that the vertical plate 10 is away from the placement seat 4. By adjusting the position of the sliding block 20 inside the sliding groove 19, the position of the vertical plate 10 can be freely adjusted according to the different lengths of the core sample body 5, which is suitable for core sample bodies 5 of various sizes, and improves flexibility and applicability. When adjusting the position of the vertical plate 10 on the other side, the driving rod 3 on the other side can be driven away from the placement seat 4 by pulling the connecting block 23, further improving flexibility and applicability. When the sliding block 20 slides inside the sliding groove 19, it will drive the fastener 22 to slide inside the limiting hole 21. After sliding to the appropriate position, the position of the sliding block 20 can be fixed by the fastener 22, so that the sliding block 20 remains stable during operation and the risk of displacement is reduced.

[0040] Reference Figure 1 and Figure 4 The connecting mechanism includes a horizontal plate 12 fixedly connected to one side of the vertical plate 10, a threaded rod 13 is threadedly connected to the top of the horizontal plate 12, a handle 14 is fixedly connected to the top of the threaded rod 13, and the bottom end of the threaded rod 13 passes through the horizontal plate 12 and is rotatably connected to a clamping plate 15, which contacts the core sample body 5 when moving.

[0041] A clamping groove is provided on one side of the clamping plate 15 close to the core sample body 5 , and the clamping groove is arranged in an arc shape.

[0042] In addition, a rubber pad 16 is fixedly connected to one side of the clamping groove close to the core sample body 5 , and the rubber pad 16 is adapted to the shape of the clamping groove.

[0044] When the core sample body 5 is placed on the horizontal plates 11 on both sides, the threaded rod 13 is driven by rotating the handle 14 to move the threaded rod 13 downward. The threaded rod 13 moves downward and drives the clamping plate 15 to clamp and fix the core sample body 5 downward. The core sample body 5 is fixed by the clamping plate 15, which can increase the contact area between the vertical plate 10 and the core sample body 5, improve the stability between the vertical plate 10 and the core sample body 5, make the core sample body 5 stable during rotation, reduce the risk of displacement of the core sample body 5 during rotation, and when the clamping block clamps the core sample body 5 When holding, the clamping groove is set to an arc shape so that it can better fit the shape of the core sample body 5.

The rotation of the vertical plate 10 drives the core sample body 5 to rotate on the top of the placement seat 4, and then start the cutting device 9 so that the cutting device 9 cuts the rotating core sample body 5 downward. By slowly cutting the cutting knife toward the inside of the core sample body 5, the risk of missing corners caused by cutting from one side to the other side can be reduced.

[0046] By pulling the sliding block 20 on one side to move inside the sliding groove 19, the movement of the sliding block 20 drives the mounting seat 1 to move, and the movement of the mounting seat 1 causes the driving rod 3 to move inside the cutting box 6, so that the vertical plate 10 is away from the placement seat 4. By adjusting the position of the sliding block 20 inside the sliding groove 19, the cutting position can be freely adjusted according to the different lengths of the core sample body 5. By turning the handle 14, the threaded rod 13 is driven to move downward, and the downward movement of the threaded rod 13 drives the clamping plate 15 to clamp and fix the core sample body 5 downward.
