Description

Technical Field

[0001] The utility model relates to the technical field of fracturing machines, in particular to an integrated hydraulic formation core fracturing machine. Background Art

[0002] Existing fracturing machines include those that use oil pressure, air pressure, and mechanical forces to generate driving force. Fracturing machines can perform fracturing experiments on naturally formed rocks or artificially made concrete test blocks, thereby judging the ability of these fracturing materials to resist pressure through fracturing data, and then understanding their properties and mechanical properties.

[0003] There are many fracturing machines on the market. During the actual fracturing process, the fracturing plate of the fracturing machine will squeeze downward, causing cracks or collapse in the specimen. In daily operation, the fracturing specimen will cause a part of the powdered material on the surface of the fracturing plate to adhere to the surface of the fracturing plate with a certain cohesive force.

[0004] During the operation, the operator generally does not remove the fracturing material adhered to the surface of the fracturing plate. Therefore, when the next fracturing operation is performed on a new specimen, the fracturing material adhered to the fracturing plate will first contact the specimen, which will affect the experimental data of the fracturing operation to a certain extent, and thus affect the fracturing test results to a certain extent. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology and propose an integrated hydraulic formation core fracturing machine to solve the technical problem mentioned in the background technology that some existing fracturing machines do not clean the fracturing materials adhered to their fracturing plates during operation, thereby affecting the fracturing test.

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

[0007] An integrated hydraulic formation core fracturing machine includes a base plate, four vertical guide columns arranged on the base plate, a mounting plate slidably sleeved between the four guide columns, and a fracturing plate fixed to the bottom of the mounting plate, wherein the base plate is provided with a first telescopic drive member whose telescopic end can be horizontally extended toward the fracturing plate, the telescopic end of the first telescopic drive member is fixed to a mounting frame, a slider is provided on the mounting frame for vertical sliding, a scraper is provided on the slider, and a second telescopic drive member whose telescopic end can be vertically extended and retracted and the telescopic end is fixed to the mounting frame.

[0008] Working principle:

[0009] The operator places the test piece to be fractured on the base plate, and then drives the mounting plate and the fracturing plate downward by external force until the fracturing plate contacts the test piece. The test piece is pressed into cracks or fractured according to the operating requirements, and then the fractured test piece is taken out.

[0010] The operator then needs to clean the fracturing material adhered to the surface of the fracturing plate. Specifically, the fracturing plate is first slid vertically to a position suitable for cleaning. The operator then drives the mounting frame to move through the first telescopic drive member until the mounting frame drives the slider and scraper to move, so that the scraper blade contacts the bottom surface of the fracturing plate. The telescopic end of the first telescopic drive member continuously pushes the mounting frame to move horizontally. At this time, the scraper blade can continuously scrape along the bottom surface of the fracturing plate, thereby scraping off the adhesive material adhered to the bottom of the fracturing plate. During this process, the operator activates the second telescopic drive member, and the telescopic end of the second telescopic drive member continuously pushes the slider upward, thereby indirectly driving the scraper blade to continuously contact the bottom of the fracturing plate with pressure, thoroughly cleaning the fracturing material adhered to the bottom of the fracturing plate.

[0011] The beneficial effects of the utility model are:

[0012] During the use of the utility model, the operator can drive the blade of the scraper to slide continuously along the bottom plate surface of the fracturing plate through the first telescopic drive member, thereby scraping off the fracturing materials adhered to the fracturing plate, and continuously push the slider and the scraper through the telescopic end of the second telescopic drive member, so that the blade of the scraper continuously presses against the bottom of the fracturing plate, which can more thoroughly clean the fracturing materials adhered to the bottom of the fracturing plate.

[0013] This structure can clean the bottom surface of the fracturing plate in time, thereby ensuring normal use next time, and further facilitating the accuracy of fracturing test data. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, an integrated hydraulic formation core fracturing machine includes a base plate 1, four vertical guide columns 2 arranged on the base plate 1, a mounting plate 3 slidably sleeved between the four guide columns 2 and a fracturing plate 4 fixed to the bottom of the mounting plate 3, the base plate 1 is provided with a first telescopic driving member 5 whose telescopic end can be horizontally extended toward the fracturing plate 4, the telescopic end of the first telescopic driving member 5 is fixed with a mounting frame 6, the mounting frame 6 is provided with a slider 7 for vertical sliding, the mounting frame 6 is provided with a vertical slide groove 22, the slider 7 is slidably arranged in the slide groove 22, the slider 7 is provided with a scraper 8 whose blade can move downward with the fracturing plate 4 and abut against the bottom of the fracturing plate 4, and the mounting frame 6 is fixed with a second telescopic driving member 9 whose telescopic end can be vertically extended and the telescopic end is fixedly connected to the slider 7. The operator can drive the blade of the scraper 8 to slide continuously along the bottom surface of the fracturing plate 4 through the first telescopic drive member 5, thereby scraping off the fracturing materials adhered to the fracturing plate 4, and continuously push the slider 7 and the scraper 8 through the telescopic end of the second telescopic drive member 9, so that the blade of the scraper 8 continuously pressurizes against the bottom of the fracturing plate 4, which can more thoroughly clean the fracturing materials adhered to the bottom of the fracturing plate 4.

[0020] like Figure 1 、 Figure 2 and Figure 3As shown, a connecting plate 10 is fixed on the slider 7, and the scraper 8 is hinged to the connecting plate 10. A connecting component is provided between the connecting plate 10 and the scraper 8 for driving the scraper 8 to rotate relative to the connecting plate 10. During use, the blade of the scraper 8 may be worn flat. At this time, the operator can adjust the angle of the blade of the scraper 8 by rotating the connecting component, so that other replaceable blade parts of the scraper 8 are abutted against the bottom of the fracturing plate 4, thereby further ensuring the scraping efficiency of the scraper 8 on the fracturing plate 4. The connecting assembly includes two threaded rods 11 and a threaded sleeve 12. The threaded directions of the two threaded rods 11 are opposite, one of the threaded rods 11 is hinged to the connecting plate 10, and the other threaded rod 11 is hinged to the scraper 8. The open pipe sections at both ends of the threaded sleeve 12 are respectively threadedly connected to the two threaded rods 11 in a one-to-one correspondence. The operator can adjust the rotation angle of the scraper 8 by rotating the threaded sleeve 12. This adjustment can adjust the rotation angle of the scraper 8 more finely, making it easier for the blade of the scraper 8 to abut against the bottom of the fracturing plate 4. A collection box 13 with an open top is fixed to the connecting plate 10. The blade of the scraper 8 corresponds to the opening at the top of the collection box 13 in the upper and lower directions. The fracturing material scraped off by the scraper 8 can fall into the collection box 13, which is more clean. The first telescopic drive member 5 and the second telescopic drive member 9 are both cylinder structures. The cylinder structure has stable performance, stable telescopic performance, high degree of automation, and is conducive to reducing production costs. A first connecting piece 16 is fixed on the connecting plate 10, and a first rotating rod 17 is rotatably passed through the first connecting piece 16. The first rotating rod 17 is fixedly connected to one of the threaded rods 11. A second connecting piece 18 is fixed on the scraper 8, and a second rotating rod 19 is rotatably passed through the second connecting piece 18. The other threaded rod 11 is fixedly connected to the second rotating rod 19. A third connecting piece 20 is fixed on the connecting plate 10, and a third rotating rod 21 is rotatably passed through the third connecting piece 20. The scraper 8 is fixedly connected to the third rotating rod 21.

[0021] like Figure 1 As shown, the first telescopic drive member 5 is rotatably connected to the base plate 1. Through the rotational connection, the operator can rotate the first telescopic drive member 5 and other structural components mounted thereon to a position away from the fracturing plate 4, thereby facilitating the operator to place the test piece on the base plate 1. A vertical rotating shaft 14 is rotatably provided on the base plate 1, and the first telescopic drive member 5 is fixedly connected to the top of the rotating shaft 14. This type of rotational connection has a simple structure and is more practical. A motor 15 is fixed to the bottom of the base plate 1, and the bottom of the rotating shaft 14 is provided at the output end of the motor 15. The rotating shaft 14 is driven to rotate by the motor 15, and then the rotating shaft 14 drives the first telescopic drive member 5 to rotate. This method is more automated, saves time and effort, and improves the efficiency of the fracturing operation.

[0022] Working principle:

[0023] The operator places the test piece to be fractured on the base plate 1. The operator can rotate the first telescopic drive member 5 and the structural parts thereon to a position away from the fracturing plate 4 through the cooperation of the motor 15 and the rotating shaft 14, and place the test piece on the base plate 1. Then, the operator drives the mounting plate 3 and the fracturing plate 4 downward by external force until the fracturing plate 4 contacts the test piece. The test piece can be pressed into cracks or fractured according to the operating requirements, and then the fractured test piece can be taken out.

[0024] Then the operator needs to clean the fracturing material adhered to the surface of the fracturing plate 4. Specifically, first slide the fracturing plate 4 vertically to a position suitable for cleaning. Then the operator drives the mounting frame 6 to move through the first telescopic drive member 5 until the mounting frame 6 drives the slider 7 and the scraper 8 to move, so that the blade of the scraper 8 contacts the bottom surface of the fracturing plate 4. The telescopic end of the first telescopic drive member 5 continuously pushes the mounting frame 6 to move horizontally. At this time, the blade of the scraper 8 can continuously scrape along the bottom surface of the fracturing plate 4, thereby scraping off the adhesive material adhered to the bottom of the fracturing plate 4. During this process, the operator activates the second telescopic drive member 9. The telescopic end of the second telescopic drive member 9 continuously pushes the slider 7 upward, thereby indirectly driving the blade of the scraper 8 to continuously contact the bottom of the fracturing plate 4 with pressure, and thoroughly cleaning the fracturing material adhered to the bottom of the fracturing plate 4.

[0025] When it is necessary to adjust the rotation angle of the scraper 8 relative to the connecting plate 10, the operator can rotate the threaded sleeve 12 to realize the rotation of the scraper 8. Finally, the scraped fracturing material will fall into the collection box 13, and the operator can take the fracturing material out of the collection box 13.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
