Description

Technical Field

[0001] This invention relates to the field of cutting technology for strip samples in geotechnical engineering, and more specifically to a cutting device for strip samples. Background Technology

[0002] Indoor geotechnical engineering experiments are essential for obtaining soil strength parameters in offshore wind power exploration. Clay samples used in indoor geotechnical engineering experiments are generally obtained by drilling, sampling, and transporting them to the laboratory from the field. Subsequently, the clay samples are cut and prepared into experimental soil samples of the dimensions required for indoor geotechnical engineering experiments.

[0003] Currently, the soil samples used in indoor geotechnical engineering experiments are generally manually cut by laboratory technicians using tools such as shaving knives and ring cutters until the clay samples meet the experimental requirements. However, the method of manually cutting clay samples is greatly affected by human factors and relies heavily on the experience of the operator. Experimental soil samples prepared by different technicians often have quality differences. Furthermore, the long manual cutting process can lead to significant moisture loss from the clay samples. Instability in the cutting force and boundary constraints of the soil samples can also cause damage to the clay sample structure.

[0004] An existing fully automatic rotary thin-walled soil cutter consists of a motor, an upper soil sample fixing rod, a lower soil sample fixing rod, and an arc-shaped thin-walled cutting blade. The soil sample to be cut is clamped between the upper and lower soil sample fixing rods. The motor drives the arc-shaped thin-walled cutting blade to rotate and move up and down to cut the soil sample to obtain a sample of the corresponding diameter. However, this fully automatic rotary thin-walled soil cutter can only cut soil samples of the corresponding axial length. Before cutting, a laboratory technician still needs to cut the soil sample to the corresponding length. Because the shape of the soil sample before cutting is not regular, it may not be possible to ensure that the cutting surface is perpendicular to the length direction, resulting in a skewed cutting surface. This makes the soil sample placed on the lower soil sample fixing rod skewed, making it difficult to align with the lower soil sample fixing rod. During the cutting process, there may be local over-cutting and local under-cutting, making it difficult to meet the requirements in terms of both diameter and length of the prepared experimental soil sample. There are quality differences between experimental soil samples, and the cutting process is time-consuming. Summary of the Invention

[0043] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figures 1 to 3As shown, this embodiment discloses a cutting device for a strip-shaped sample, including a first slide rail 1, a fixed structure 2, a movable structure 3, a first power structure 4, a cutting blade 5, a support 6, a second power structure 7, and a cutting blade 8. The fixed structure 2 is disposed at one end of the first slide rail 1 and is adapted to fix one end of the strip-shaped sample to be cut; the movable structure 3 is slidably connected to the first slide rail 1 and is adapted to fix the other end of the strip-shaped sample; the first power structure 4 is disposed at one end of the first slide rail 1 and includes a first power output end 401 that rotates about a first direction; one end of the cutting blade 5 is connected to the first power output end 401. The outer periphery is detachably fixedly connected, and the length extension direction of the other end is parallel to the first direction; it is suitable for rotary cutting of the strip sample; the bracket 6 is spaced apart on the side of the first slide 1, including a second slide 601 extending along the sliding direction of the first slide 1; the second power structure 7 is slidably connected to the second slide 601, including a second power output end that reciprocates along the second direction; the cutting blade 8 is connected to the second power output end and is suitable for cutting the strip sample into segments; the first direction is parallel to the sliding direction of the first slide 1, and the second direction is perpendicular to the first direction.

[0045] The strip-shaped sample cutting device provided in this embodiment includes a first slide rail 1, a fixed structure 2, a movable structure 3, a first power structure 4, a cutting blade 5, a support 6, a second power structure 7, and a cutting blade 8. The fixed structure 2 and the movable structure 3 can support and fix the strip-shaped sample to be cut along its length direction, preventing the strip-shaped sample to be cut from moving along its length direction and preventing differences in cutting dimensions caused by the movement of the strip-shaped sample along its length direction during the cutting process. Since the movable structure 3 is slidably connected to the first slide rail 1, the fixed structure 2 and the movable structure 3 can support and fix strip-shaped samples of different lengths, making it widely applicable. The first power output end 401 of the first power structure 4 is rotatable, and the cutting blade 5 rotates under the drive of the first power output end 401, thereby cutting the strip-shaped sample into samples of the corresponding diameter. The support 6 can slide to support the second power structure 7, allowing the second power structure 7 to reciprocate along the second slide rail 601, thereby driving the cutting blade 8 to move in a direction parallel to the first direction, and the second power output end to reciprocate along the second direction, thus cutting the strip-shaped sample into corresponding sample segments according to the required length. The strip-shaped sample cutting device provided by this invention can cut the strip-shaped sample into samples of the corresponding diameter using the first power structure 4 and the cutting blade 5, and can also cut the strip-shaped sample into sample segments of the corresponding length using the second power structure 7 and the cutting blade 8. There is no difference in quality between the various sample segments after cutting, and no manual cutting is required, with a short cutting time. Specifically, the strip-shaped sample can be a long strip of test soil sample, or other samples that are easy to cut.

[0046] The cutting device for the strip sample in this embodiment further includes a third power structure 9 and a first transmission structure 10; the third power structure 9 is disposed at the other end of the first slide rail 1 and includes a third power output end that rotates about a third direction, the third direction being parallel to the first direction; the first transmission structure 10 is connected to the third power output end and the second power structure 7, and is adapted to drive the second power structure 7 to slide along the second slide rail 601.

[0047] The third power structure 9 can provide power for the sliding of the second power structure 7, making it easier to adjust the position of the cutting blade 8 to achieve the purpose of cutting to the required length.

[0048] In this embodiment, the first transmission structure 10 includes a first lead screw 1001 and a transmission plate 1002. The first lead screw 1001 is fixedly connected to the third power output end, and one end is rotatably connected to the bracket 6 through a first bearing. One end of the transmission plate 1002 is provided with a first threaded hole and is connected to the first lead screw 1001 through the first threaded hole. One side of the other end is slidably connected to the second slide rail 601 through a first roller, and the other side of the other end is fixedly connected to the second power structure 7. Since the transmission plate 1002 is slidably connected to the second slide rail 601 through the first roller, when the first lead screw 1001 rotates, the transmission plate 1002 will not rotate with it, but will move along the axial direction of the first lead screw 1001. The movement of the transmission plate 1002 drives the second power structure 7 and the cutting blade 8 to move.

[0049] Furthermore, the first transmission structure 10 also includes a gear assembly, which includes a first gear and a second gear that mesh with each other. The first gear is connected to the third power output end; the first lead screw 1001 is fixedly connected to the second gear.

[0050] In this embodiment, the first power structure 4 further includes a first motor, and the first power output end 401 is the rotating shaft of the first motor; the first motor realizes automatic control of the cutting blade 5, realizes automatic cutting of strip-shaped samples, has high cutting accuracy, fast cutting speed, less soil moisture loss, and reduces damage to the soil sample structure.

[0051] In this embodiment, the second power structure 7 further includes a hydraulic cylinder, and the second power output end is the extension end of the hydraulic cylinder; the hydraulic cylinder enables automatic control of the cutting blade 8, realizes automatic cutting of strip-shaped samples, has high cutting accuracy, better ensures the perpendicularity of the cutting surface to the strip-shaped sample, reduces the quality difference between the various soil sample segments after cutting, and has a shorter cutting time.

[0052] In this embodiment, the third power structure 9 further includes a second motor, and the third power output end is the shaft of the second motor. The second motor enables automatic control of the cutting length, resulting in higher cutting accuracy, eliminating the need for measurement before cutting, and shortening the cutting time.

[0053] In this embodiment, the fixing structure 2 includes a fixing post 201 and a plurality of first pins 202. One end of the fixing post 201 is fixedly connected to the end face of the first power structure 4 facing the first slide 1. The plurality of first pins 202 protrude from the other end of the fixing post 201 and are suitable for insertion into one end of the strip sample. The first power output end 401 is an annular shaft. The fixing post 201 passes through the interior of the first power output end 401 and forms an annular gap with the first power output end 401.

[0054] The fixing post 201 is inserted inside the first power output end 401, forming an annular gap between it and the first power output end 401. When the first power output end 401 rotates, it will not cause the fixing post 201 to rotate, nor will it interfere with the fixing post 201. This allows the fixing post 201 and the first insert 202 to fix the strip-shaped sample, thereby enabling the cutting of the strip-shaped sample. The first insert 202 is easily inserted into the strip-shaped sample. Several first inserts 202 are distributed in a ring shape along the circumference of the fixing post 201, and the ring-shaped needles are distributed in multiple rings along the radial direction of the fixing post 201.

[0055] The cutting device for strip-shaped samples in this embodiment also includes a rotating plate 11, which is sleeved on the outer periphery of the first power output end 401. The rotating plate 11 has a plurality of connecting holes 1101 spaced radially along the first power output end 401. The cutting blade 5 is detachably connected to the connecting holes 1101. The cutting blade 5 can be connected to different connecting holes 1101 according to the required diameter to be cut, thereby cutting soil samples of different diameters.

[0056] In this embodiment, the top of the movable structure 3 is provided with an oil groove 3011, which is suitable for holding lubricant. The cutting blade 5 is slidably disposed within the oil groove 3011. Before cutting, the movable structure 3 can be moved to lubricate the cutting blade 5, ensuring smooth cutting. Simultaneously, during the cutting process, an oil film can be formed on the surface of the strip-shaped sample to prevent moisture loss from the soil sample. Furthermore, the cutting blade 5 is a needle-shaped blade, and the oil groove 3011 is a through groove penetrating the top of the movable structure 3; preferably, the oil groove 3011 is an arc-shaped through groove. The lubricant can be petroleum jelly, etc.

[0057] In this embodiment, the movable structure 3 includes a movable plate 301, a plurality of second pins 302, a fourth power structure 303, and a second transmission structure 304; the bottom end of the movable plate 301 is slidably connected to the first slide rail 1, and the top end is provided with the oil groove 3011; the plurality of second pins 302 protrude from one end of the movable plate 301 facing the fixed structure 2, and are suitable for being inserted into the other end of the strip sample; the fourth power structure 303 is provided at the other end of the first slide rail 1, and includes a rotating fourth power output end; the second transmission structure 304 drives the fourth power output end and the movable plate 301, and is suitable for driving the movable plate 301 to slide along the first slide rail 1.

[0058] The fourth power structure 303 controls the sliding plate 301 to slide along the first slide rail 1. Before fixing the strip sample, the sliding plate 301 can be moved to lubricate the cutting blade 5. After one end of the strip sample is fixed to the fixing structure 2, the sliding plate 301 is driven to slide on the first slide rail 1 until the second pin 302 is inserted into the other end of the strip sample, thus fixing the strip sample. The second transmission structure 304 transmits the power of the fourth power structure 303 to the sliding plate 301. The second pin 302 is easily inserted into the strip sample. Several second pins 302 are distributed in a ring shape along the circumference of the fixing post 201, and the ring needles are distributed in multiple rings along the radial direction of the fixing post 201. The first pin 202 and the second pin 302 are arranged opposite to each other.

[0059] In this embodiment, the first slide rail 1 is a groove-shaped slide rail, and the moving plate 301 is slidably connected to the first slide rail 1 via a second roller; the cooperation of the first slide rail 1 and the second roller limits the movement direction of the moving plate 301 and prevents the moving plate 301 from rotating. Furthermore, the second roller also reduces friction.

[0060] In this embodiment, the second transmission structure 304 includes two support seats 3041 and a second lead screw 3042. The two support seats 3041 are respectively disposed at both ends of the first slide rail 1. One end of the second lead screw 3042 is connected to the fourth power output end, and the other end is rotatably connected to the two support seats 3041 through bearings. The moving plate 301 is provided with a second threaded hole. The moving plate 301 is connected to the second lead screw 3042 through the second threaded hole and is located between the two support seats 3041.

[0061] The two support seats 3041 can support the second lead screw 3042 to the corresponding height, which facilitates the cooperation between the movable plate 301 and the first slide rail 1. Since the movable plate 301 is slidably connected to the first slide rail 1 through the second roller, when the second lead screw 3042 rotates, the movable plate 301 will not rotate with it, but will move along the axial direction of the second lead screw 3042.

[0062] The cutting device for the strip sample in this embodiment also includes a support structure 12. The support structure 12 includes two sets of support components arranged at intervals. Each set of support components includes at least two support blocks 1201 distributed at intervals along the first direction. Each support block 1201 is provided with a support groove 1202. The support grooves 1202 of the two sets of support components are arranged opposite to each other and are supported on both sides of the bottom of the strip sample along the length direction of the strip sample. The first slide rail 1 is arranged between the two sets of support components.

[0063] The support structure 12 not only supports both sides of the bottom of the strip sample, preventing it from bending under gravity and affecting the cutting quality, but also provides clearance for the movement of the moving plate 301, allowing it to move closer to the fixed structure 2 for comprehensive lubrication of the cutting tool 5. Preferably, the support groove 1202 is an arc-shaped groove, with the groove openings of the two sets of support components facing each other.

[0064] The cutting device for strip-shaped samples in this embodiment also includes an operating table 13, with the first slide rail 1 disposed on the top of the operating table 13; the first power structure 4 is detachably connected to the top of the operating table 13 and located at one end of the support structure 12; one end of the bracket 6 is connected to the top of the operating table 13 and located at the other end of the support structure 12, and the other end extends upward and bends into an extension portion, with the second slide rail 601 disposed on the extension portion.

[0065] The first slide rail 1 can be a groove formed on the top of the operating table 13, or it can be a slide bar provided on the top of the operating table 13, with a groove on the top of the slide bar. The first power structure 4 is detachably connected to the top of the operating table 13 by fasteners such as screws. The bracket 6 can be welded to the operating table 13. The third power structure 9 and the fourth power structure 303 can both be detachably connected to the operating table 13 by fasteners such as screws. The extension includes a first bent section covering the third power structure 9 and the fourth power structure 303, and also includes a second bent section extending above the first slide rail 1, with the second slide rail 601 provided on the second bent section.

[0066] The cutting device for strip-shaped samples in this embodiment also includes several rib-shaped clamps, which are fixedly connected to the second power output end and connected to the cutting blade 8; the rib-shaped clamps can increase the strength of the cutting blade 8.

[0067] In this embodiment, the cutting tool 5 is a needle knife.

[0068] The cutting device for strip samples in this embodiment includes pre-cutting preparations. These preparations include adjusting the installation height of the cutting blade 5 according to the diameter of the strip sample to be cut and the diameter of the sample after cutting, installing a movable plate 301 at a suitable height, activating the fourth power structure 303, controlling the reciprocating movement of the movable plate 301, and lubricating the cutting blade 5 by passing it through the oil groove 3011. After the preparatory work before cutting is completed, the strip-shaped soil sample is placed on the support structure 12. First, the first pin 202 is inserted into one end of the strip-shaped sample. Then, the fourth power structure 303 is activated to control the moving plate 301 to move towards the fixed structure 2, and the second pin 302 is inserted into the other end of the strip-shaped sample to complete the fixation and support of the strip-shaped sample. Then, the first power structure 4 is activated to drive the cutting blade 5 to rotate and cut. After cutting, the cutting blade 5 is disassembled, and the third power structure 9 is activated to drive the second power structure 7 to move to the position of the strip-shaped soil sample of the required length for the experiment. Then, the second power structure 7 is activated to drive the cutting blade 8 to cut the strip-shaped sample. After cutting is completed, the fourth power structure 303 is activated to make the second pin 302 disengage from the sample, and the sample can be removed.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
