Description

Technical Field

[0001] This utility model belongs to the technical field of concrete impact and abrasion testing equipment, and particularly relates to an underwater steel ball method impact and abrasion testing device. Background Technology

[0002] In water conservancy engineering and related fields, the abrasion resistance of concrete is one of the key indicators for evaluating the durability and applicability of concrete materials. The underwater steel ball method, a commonly used test method for concrete abrasion resistance, simulates the abrasive effect of water containing sediment on concrete specimens to test and evaluate the abrasion resistance of concrete. This method has wide applications in hydraulic concrete and other engineering fields, and is of great significance for ensuring the long-term stability and safety of engineering structures.

[0003] However, in practical applications, existing underwater steel ball abrasion resistance testing devices for concrete have several inconveniences. First, the abrasion test blocks are usually quite heavy, and accurately placing them into the abrasion cylinder requires disassembling a large number of bolts, which is cumbersome and time-consuming. Simultaneously, during disassembly, the bottom plate sealing ring is prone to movement, leading to frequent leaks. This not only affects the accuracy of the test but also wastes a significant amount of time and effort. Furthermore, the distances between the agitator and the upper surface of the test block, as well as the distance between the water level and the upper surface of the test block, need to be strictly controlled during the test to ensure the accuracy and consistency of the test conditions. However, conventional testing equipment often makes it difficult to observe these height parameters, leading to measurement errors and further affecting the reliability of the test results. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing an anti-abrasion device for underwater steel ball method.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a device for underwater steel ball anti-abrasion, comprising a mounting frame, a column on the mounting frame, a lifting component on the column, a support column on the lifting component, a first motor on the support column, a stirring component installed at the output end of the first motor, an abrasion steel cylinder mounted on the surface of the mounting frame, an auxiliary component on the lifting component, and a sample-bearing frame located inside the abrasion steel cylinder on the auxiliary component.

[0006] By adopting the above technical solution, the device, through its integrated design, enables convenient installation and operation of concrete specimens in the underwater steel ball impact abrasion test. The lifting component design allows for flexible height adjustment of the mixing component and the sample-supporting frame, facilitating the placement of specimens of different sizes and improving the device's versatility and flexibility. The sample-supporting frame ensures the stability and accuracy of the specimens during the impact abrasion process, guaranteeing the reliability of the test results.

[0007] Optionally, the mounting frame includes a supporting base plate and a supporting top plate, and a plurality of fixing rods are provided between the supporting base plate and the supporting top plate.

[0008] By adopting the above technical solution, the mounting frame uses a structure in which the supporting base plate and the supporting top plate are connected by a fixed rod, which enhances the overall stability and load-bearing capacity of the device. This design enables the device to remain stable even when subjected to large impact and grinding forces, thereby improving the safety and accuracy of the test.

[0009] Optionally, the column is provided with an installation groove for installing the lifting component, and a pair of directional slides are provided on the side wall of the installation groove.

[0010] By adopting the above technical solution, the mounting groove and directional slide provided on the column provide a stable installation foundation and guidance for the lifting component, which ensures the stability and accuracy of the lifting component during the lifting process and avoids test errors caused by shaking or deviation.

[0011] Optionally, the lifting component includes a second motor installed on the upper end of the column. A lead screw is installed at the output end of the second motor. The end of the lead screw away from the second motor is connected to the mounting groove through a bearing seat. A pair of lead screw seats are provided on the outer periphery of the lead screw. The support column is connected to one of the lead screw seats, and the other lead screw seat is connected to the auxiliary component.

[0012] By adopting the above technical solution, the lifting component uses a motor-driven lead screw rotation, which in turn drives the lead screw seat to rise and fall, thus realizing the height adjustment of the stirring component and the sample support frame. This design not only improves the convenience of experimental operation, but also ensures the accuracy and consistency of experimental conditions, providing strong support for the reliability of experimental results.

[0013] Optionally, the outer sides of the pair of wire seats are respectively provided with directional slides connected to the pair of directional slides.

[0014] By adopting the above technical solution, the directional slide on the outside of the wire seat cooperates with the directional slide on the column, which further enhances the stability and accuracy of the lifting component during the lifting process. This design effectively avoids shaking and deviation during the lifting process, and improves the accuracy and reliability of the test.

[0015] Optionally, the stirring component includes a stirring shaft, and stirring blades are mounted on the end of the stirring shaft away from the first motor.

[0016] By adopting the above technical solution, the scale on the agitator provides the test personnel with an intuitive height reference, which facilitates accurate control of the distance between the agitator blade and the upper surface of the test block and the water level. This design not only improves the convenience of the test operation, but also ensures the accuracy and consistency of the test conditions, providing an important guarantee for the reliability of the test results.

[0017] Optionally, the auxiliary component includes an auxiliary rod connected to the lifting component, and an auxiliary seat located on the outer periphery of the stirring component is installed at the other end of the auxiliary rod. The outer periphery of the auxiliary seat is provided with a rotating groove.

[0018] By adopting the above technical solution, the design of the auxiliary component provides a stable support and rotation foundation for the sample-bearing frame. The rotation groove on the auxiliary seat allows the sample-bearing frame to rotate flexibly, which facilitates the installation and removal of the test block and improves the convenience of the test operation. At the same time, the connection between the auxiliary component and the lifting component allows the lifting component to drive the auxiliary component to rise and fall, thereby driving the sample-bearing frame to rise and fall.

[0019] Optionally, the sample-bearing frame includes a pair of arc-shaped skeletons connected to the rotating groove. Each pair of arc-shaped skeletons is provided with a connecting column. A connecting frame is installed at the other end of the connecting column. A sample-bearing grid is provided inside the connecting frame. The pair of connecting frames are connected by a rotating shaft. The arc-shaped skeletons and the connecting frames are respectively in the form of a quarter-circle fan-shaped structure.

[0020] By adopting the above technical solution, the sample support frame adopts an arc-shaped skeleton and connecting frame design, which enables the test block to be placed stably on the sample support grid. This design not only improves the stability of the test block during the grinding process, but also facilitates the installation and removal of the test block. At the same time, the quarter-circle fan-shaped structure of the arc-shaped skeleton and connecting frame also makes the sample support frame more flexible during rotation, improving the convenience of the test operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The design of the lifting component and the sample-bearing frame enables convenient installation and operation of the test block. The sample-bearing frame can rotate flexibly, facilitating the placement and removal of the test block. At the same time, the lifting component can precisely adjust the height of the test block and the mixing component, avoiding the cumbersome bolt disassembly process in traditional devices, improving test efficiency, and solving problems such as the large weight of the grinding test block, the cumbersome and time-consuming operation of placing it into the grinding steel cylinder, and the easy movement of the bottom plate sealing steel ring leading to water leakage.

[0023] 2. A scale is installed on the stirring shaft, providing testers with an intuitive height reference, facilitating accurate control of the distance between the stirring blades and the upper surface of the test block, as well as the water level. Furthermore, the design of the directional slide and directional slide block ensures the stability and accuracy of the lifting components during the lifting process, avoiding test errors caused by shaking or offset, and improving the precision and reliability of the test. Conventional test equipment does not easily allow for observation of the distance between the stirring blade and the upper surface of the test block, as well as the distance between the water level and the upper surface of the test block, leading to measurement errors.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figure 1As shown in Figure 4, the specific solution of the embodiment is as follows: A device for underwater steel ball method anti-impact abrasion includes a mounting frame 1, which includes a supporting base plate 101 and a supporting top plate 102. A plurality of fixing rods 103 are provided between the supporting base plate 101 and the supporting top plate 102. The mounting frame serves as the basic structure of the entire device, providing a stable support platform. The supporting base plate 101 and the supporting top plate 102 are connected by fixing rods 103, which enhances the overall stability and load-bearing capacity of the device and ensures that the device can remain stable when subjected to large impact abrasion forces, thus providing a guarantee for the safety and accuracy of the test.

[0032] The mounting frame 1 is provided with a column 2, and the column 2 is provided with a mounting groove 201 for mounting the lifting component 3. The side wall of the mounting groove 201 is provided with a pair of directional slides 202. The column 2 serves as the mounting base for the lifting component 3, and the mounting groove 201 on it provides a stable mounting space for the lifting component 3. The directional slides 202 on the side wall of the mounting groove 201 provide guidance for the lifting component 3 during the lifting process, ensuring the stability and accuracy of the lifting component 3 during the lifting process.

[0033] The column 2 is equipped with a lifting component 3, which includes a second motor 31 installed at the upper end of the column 2. A lead screw 32 is installed at the output end of the second motor 31. The end of the lead screw 32 away from the second motor 31 is connected to the mounting groove 201 through a bearing seat. A pair of lead seats 33 are provided on the outer periphery of the lead screw 32, and the other lead seat 33 is connected to the auxiliary component 8. The outer sides of the pair of lead seats 33 are respectively provided with directional slide seats 331 connected to a pair of directional slides 202. The lifting component 3 is equipped with a support column 4, which is connected to one of the lead seats 33.

[0034] The lifting component 3 is driven by the second motor 31 to rotate the lead screw 32, which in turn drives the lead screw seat 33 to move on the lead screw 32, thereby adjusting the height of the stirring component 6 and the sample frame 9. This design not only improves the convenience of the test operation, but also ensures the accuracy and consistency of the test conditions. The directional slide 331 on the outside of the lead screw seat 33 cooperates with the directional slide 202 on the column 2, further enhancing the stability and accuracy of the lifting component 3 during the lifting process, and avoiding test errors caused by shaking or deviation.

[0035] The support column 4 is equipped with a first motor 5. The support column 4 serves as the mounting base for the first motor 5, which is stably supported on the lifting component 3. The first motor 5 drives the stirring component 6 to rotate, providing the necessary grinding power for the test. The design of the support column 4 ensures the stability of the first motor 5 and the stirring component 6 during the lifting process, thereby improving the accuracy and reliability of the test.

[0036] A stirring component 6 is installed at the output end of the first motor 5. The stirring component 6 includes a stirring shaft 61. A stirring blade 62 is installed at the end of the stirring shaft 61 away from the first motor 5. The rotation of the stirring blade 62 causes the steel ball and water to form a vortex inside the grinding steel cylinder 7. The steel ball repeatedly impacts the surface of the test block under the combined action of centrifugal force and water flow, simulating the real grinding environment. By adjusting the speed of the first motor 5, the rotation speed of the stirring blade 62 can be precisely controlled, thereby adjusting the impact frequency and force of the steel ball on the test block to meet the needs of different test standards. A scale can be set on the stirring shaft 61. The scale provides the test personnel with an intuitive height reference, which facilitates accurate control of the distance between the stirring blade 62 and the upper surface of the test block, as well as the water level in the grinding steel cylinder 7.

[0037] The mounting frame 1 is equipped with a grinding steel cylinder 7. The grinding steel cylinder 7 is provided with a pair of cover plates 701. The cover plates 701 have arc-shaped notches on opposite sides to allow the stirring rod to pass through. The grinding steel cylinder 7 serves as the main container for the test and provides a grinding environment for the concrete test block. The design of the cover plates 701 ensures the sealing of the grinding steel cylinder 7 and prevents water leakage during the test. The arc-shaped notches on the cover plates 701 allow the stirring rod to pass through while maintaining the sealing of the grinding steel cylinder 7, thus improving the accuracy and reliability of the test.

[0038] The lifting component 3 is equipped with an auxiliary component 8, which includes an auxiliary rod 81 connected to the lifting component 3. The auxiliary rod 81 is connected to another screw seat 33. The other end of the auxiliary rod 81 is equipped with an auxiliary seat 82 located on the outer periphery of the stirring component 6. The outer periphery of the auxiliary seat 82 is provided with a rotating groove 83. The auxiliary component 8 is connected to the lifting component 3 through the auxiliary rod 81, providing stable support and a rotating foundation for the sample frame 9. The rotating groove 83 on the auxiliary seat 82 allows the sample frame 9 to rotate flexibly, facilitating the installation and removal of the test block. The design of the auxiliary component 8 improves the convenience of the test operation and ensures the stability of the sample frame 9 during the test.

[0039] The auxiliary component 8 is equipped with a sample-bearing frame 9 located inside the grinding steel cylinder 7. The sample-bearing frame 9 includes a pair of arc-shaped skeletons 91 connected to the rotating groove 83. Each pair of arc-shaped skeletons 91 is equipped with a connecting column 92. The other end of each connecting column 92 is equipped with a connecting frame 93. The connecting frame 93 is equipped with a sample-bearing grid 94. The pair of connecting frames 93 are connected by a rotating shaft 95. The arc-shaped skeletons 91 and the connecting frames 93 are respectively in a quarter-circle sector structure. The design of the sample-bearing frame 9 with the arc-shaped skeletons 91 and the connecting frames 93 allows the test block to be placed stably on the sample-bearing grid 94. The design of the sample-bearing grid 94 ensures the stability of the test block during the grinding process and prevents the test block from moving or falling off during the grinding process. The quarter-circle sector structure of the arc-shaped skeletons 91 and the connecting frames 93 makes the sample-bearing frame 9 more flexible during rotation, improving the convenience of the test operation. At the same time, the design of the sample-bearing frame 9 also facilitates the installation and removal of the test block, improving the test efficiency.

[0040] The working principle of the above embodiments is as follows:

[0041] The sample-bearing frame 9 is lifted above the grinding steel cylinder 7 by the lifting component 3, and the sample-bearing frame 9 is rotated to the opening position to facilitate the placement of the test block;

[0042] Place the concrete test block stably on the sample grid 94, rotate the sample frame 9 to the closed position, and ensure that the test block is completely inside the punching steel cylinder 7.

[0043] According to the test standard, steel balls of specified size and mass are added into the grinding steel cylinder 7, and an appropriate amount of water is added to ensure that the water level meets the test requirements (which can be referenced by the scale on the stirring shaft 61).

[0044] Start the lifting component 3 and adjust the height of the stirring component 6 so that the stirring blade 62 maintains the specified distance from the upper surface of the test block;

[0045] Start the first motor 5 to drive the stirring shaft 61 and stirring blades 62 to rotate, which in turn causes the steel balls and water to form a vortex to perform a grinding test on the test block.

[0046] After the experiment is completed, turn off the first motor 5, stop the rotation of the stirring blade 62, and wait for the steel ball and water to come to a complete stop. Then, lift the sample frame 9 above the grinding steel cylinder 7 using the lifting component 3.

[0047] Rotate the sample frame 9 to the opening position, remove the sample block, and observe and record the surface abrasion of the sample block.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
