Description

Technical Field

[0001] The utility model relates to the technical field of cutting detection, in particular to a cutting device for concrete core samples. Background Technique

[0002] In the fields of construction and engineering, the core drilling method is a non-destructive testing method widely used to evaluate the compressive strength of concrete structures. This method obtains samples representing the characteristics of the original concrete by drilling core samples from the concrete structure, and then conducts laboratory tests on them to determine the compressive strength. However, due to the rotation of the drill bit and the diversity of concrete structures during the drilling process, the two end faces of the obtained core samples often show irregular shapes, which will affect the subsequent test results of compressive strength.

[0003] To ensure the accuracy and repeatability of test results, these irregular end faces need to be trimmed to reach the specified length and flatness so that they can be evenly stressed during the pressure test. Currently, conventional cutting devices mostly use the structure of a traditional motor driving a cutting disc to achieve cutting. Specifically, a concrete core sample cutting machine disclosed in Chinese Patent Publication No. "CN204431508U".

[0004] Since the core samples need to be cut at both ends, it is found in the actual operation process of traditional cutting equipment that it is difficult to achieve convenient commutation cutting of the two ends of the core samples. The current method is to manually take out the core samples and then commutate them after one end is cut. This method is time-consuming and laborious. At the same time, conventional cutting devices are difficult to quickly position the cutting length, resulting in poor accuracy in controlling the length of the core samples during cutting. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages existing in the prior art, and to propose a cutting device for concrete core samples.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a cutting device for concrete core samples, including a base and a cutting component arranged on the base. A bracket is fixed above the base, and a pressing component for pressing the core sample is rotatably connected above the bracket;

[0008] Wherein, a bending frame is also fixed on one side of the base, an elevating seat is adjustably connected to the bending frame, and a stop component is arranged on one side of the elevating seat. The stop component is used to stop the end of the core sample.

[0009] Further, the pressing component includes a rotating plate rotatably connected above the bracket. Two V-shaped seats are fixed above the rotating plate. Guide grooves are formed on both sides of the V-shaped seats. A guide rod is fixedly connected between the two guide grooves on the same side. Among them, a sliding contact structure is provided between the two guide rods on both sides.

[0010] Further, two locking holes are formed on the end face of the rotating plate. A positioning glass bead is fixed above the bracket. The telescopic end of the positioning glass bead is clamped inside the locking hole.

[0011] Further, the contact structure is a U-shaped frame. The two ends of the U-shaped frame are slidably connected to the two guide rods. A cylinder is fixed above the U-shaped frame. The shaft end of the cylinder penetrates through the U-shaped frame and is fixed with a V-shaped block.

[0012] Further, positioning holes are spaced apart on the end face of the guide rod. A positioning rod is movably inserted into the side end of the U-shaped frame through a spring. The positioning rod is inserted into the positioning hole.

[0013] Further, an adjustment groove is formed on the end face of the bending frame. The end of the lifting seat is fixedly installed with a screw rod that slides in the adjustment groove. A bolt is fastened to the end of the screw rod.

[0014] Further, the stop component includes an adjustment rod threadedly connected to the lifting seat. A limiting stop disk is rotatably connected to the free end of the adjustment rod.

After one end of the core sample is cut, the pressing component can be rotated to realize the commutation of the core sample, so as to realize the convenient and rapid cutting of both ends of the core sample, effectively improving the cutting convenience and applicability of the concrete core sample.

[0023] In some embodiments, in the present invention, the pressing assembly 4 includes a rotating plate 41 rotatably connected above the bracket 3, two V-shaped seats 42 are fixed above the rotating plate 41, and the design of the two V-shaped seats 42 is for the convenient placement of the core sample. Guide grooves 43 are opened on both sides of the V-shaped seat 42, and guide rods 44 are fixedly connected between the guide grooves 43 on the same side. Among them, a sliding contact structure is provided between the two guide rods 44 on both sides.

[0024] On the basis of the above embodiment, two locking holes 411 are provided on the end surface of the rotating plate 41, and a positioning glass bead 31 is fixed on the top of the bracket 3, and the telescopic end of the positioning glass bead 31 is clamped in the inside of the locking hole 411. It should be noted that, in this embodiment, the two locking holes 411 are one hundred and eighty degrees apart and are distributed around the circumference of the rotation axis of the rotating plate 41. The design of two locking holes 411 is used to position the rotating plate 41 after it rotates one hundred and eighty degrees. In this way, when cutting the core sample, after cutting one end of the core sample, the rotating plate 41 can be rotated to align the other end of the core sample with the stop assembly 7 to achieve positioning cutting, thereby improving the convenience of cutting at both ends of the core sample.

[0025] Furthermore, the interference structure U-frame 45 in this embodiment, both ends of the U-frame 45 are slidably connected to the two guide rods 44, and a cylinder 46 is fixed above the U-frame 45. The axial end of the cylinder 46 passes through the U-frame 45 and is fixed with a V-block 47. During specific cutting, the core sample is first placed between the two V-shaped seats 42, and then the cylinder 46 can be opened to push the V-block 47 to achieve interference locking on the top of the core sample to improve the cutting stability.

[0026] In addition, in order to achieve the sliding positioning of the U-shaped frame 45, in the utility model, positioning holes 441 are spaced apart on the end surface of the guide rod 44, and the side end of the U-shaped frame 45 is movably connected with a positioning rod 452 through a spring 451, and the positioning rod 452 is plugged into the positioning hole 441.
