Description

Technical Field

[0001] This disclosure relates to the technical field of concrete performance testing equipment, and more specifically, to a rapid loading and unloading device for test blocks suitable for impact and abrasion testing machines. Background Technology

[0002] In concrete performance testing, the concrete impact and abrasion resistance testing machine is used to test the impact and abrasion resistance of concrete specimens. The steps for testing concrete specimens using the testing machine are as follows: First, pull the slide plate on the testing machine to pull out the test cylinder. Then, the operator loosens the bolts between the test cylinder and the slide plate, removes the test cylinder from the slide plate, places the specimen on the slide plate, and then fastens the test cylinder to the test cylinder. Finally, the test cylinder and the slide plate are fixed together, and the slide plate is pushed into the testing position to test the specimen.

[0003] The aforementioned technologies suffer from the following problems: The loading and unloading of test blocks largely relies on manual operation, resulting in high labor intensity, low efficiency, and potential for non-standard operation. Furthermore, improper handling during manual loading and unloading can damage the test blocks, affecting the accuracy of the test results. Simultaneously, manual loading and unloading makes it difficult to ensure consistent test block placement each time, reducing the reliability and repeatability of the test data. Moreover, in continuous testing, the slow speed of manual loading and unloading prolongs the entire testing cycle, failing to meet the demands of modern, efficient testing.

[0004] Therefore, there is an urgent need for a device that can quickly load and unload test blocks to improve testing efficiency and accuracy.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Detailed Implementation

[0043] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0044] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0045] In related technologies, before using concrete, relevant parameters of the concrete are tested, such as its impact and abrasion resistance. Impact and abrasion resistance testing machines are commonly used for this purpose. The working process of such machines is as follows: the operator pulls the slide plate of the testing machine to the specimen placement position. After the slide plate reaches the specimen placement position, the operator loosens the bolts between the specimen cylinder and the slide plate, separating the specimen cylinder from the slide plate. Then, the specimen is placed on the slide plate, and the specimen cylinder is then placed back on the specimen. Finally, the bolts between the specimen cylinder and the slide plate are tightened, and the slide plate is pushed to the testing position to test the impact and abrasion resistance of the specimen. However, this method has several problems: for example, the large number of bolts required for the operator to tighten the specimen cylinder and the slide plate reduces the efficiency of the specimen testing; improper handling during loading and unloading of specimens can easily damage them, reducing the accuracy of the test results.

[0046] Based on this, see Figure 1 , Figure 2This disclosure provides a rapid loading and unloading device for test blocks suitable for an impact and abrasion testing machine. The testing machine includes a test cylinder 1 and a sliding plate 2 disposed at the bottom of the test cylinder 1; the bottom of the test cylinder 1 has a first opening 11 and the top of the test cylinder 1 has a discharge port 12 for the test block to enter; the discharge port 12 has a sealing door 13; the sliding plate 2 has a second opening 21 that communicates with the first opening 11; the loading and unloading device is disposed at the second opening 21 for driving the test block to the testing position of the test cylinder 1 and sealing the second opening 21.

[0047] In this embodiment, when inspecting the test block, the sliding plate 2 is pulled, causing the test cylinder 1 to move to the test block placement position (the loading and unloading device follows the sliding plate 2). When the test cylinder 1 reaches the test block placement position, the loading and unloading device is adjusted, moving within the test cylinder 1. When the loading and unloading device reaches the discharge port 12, the sealing door 13 is opened, and the test block is placed into the test cylinder 1, making contact with the loading and unloading device. The loading and unloading device is then adjusted further, moving the test block to the detection position within the test cylinder 1. Simultaneously, the loading and unloading device seals the second opening 21. Finally, a detection liquid is introduced into the test cylinder 1 to detect the impact resistance and abrasion resistance of the test block. The loading and unloading device in this embodiment eliminates the need for repeated disassembly and reassembly of the test cylinder 1 and sliding plate 2 by operators, thus improving the efficiency of test block inspection.

[0048] In some embodiments of this disclosure, see Figure 1 , Figure 2 The loading and unloading device includes a loading and unloading plate 3 and a driving component 4; the loading and unloading plate 3 is located inside the test cylinder 1 and is used to carry the test block, and the loading and unloading plate 3 has a water inlet 31; the driving component 4 is used to drive the loading and unloading plate 3 to move up and down inside the test cylinder 1.

[0049] As an example, the diameter of the loading / unloading tray 3 can be 302 mm; the thickness can be 2 mm; and the height can be 30 mm.

[0050] The loading and unloading tray 3 allows the test block to move smoothly within the test cylinder 1, thus improving the quality of the test block testing. Simultaneously, the loading and unloading tray 3 provides better protection for the concrete sample, reducing the probability of concrete damage and improving the accuracy of the concrete test results. Furthermore, the loading and unloading tray 3 is easy to clean later, requiring only rinsing with water, further improving the efficiency of test block testing.

[0051] As another example, see Figure 1 , Figure 2The drive component 4 can be a jack 41; the loading and unloading plate 3 is installed at the output end of the jack 41, wherein the direction of movement of the jack 41 is the same as the axis of the test cylinder 1. When it is necessary to drive the loading and unloading plate 3 to move inside the test cylinder 1, the jack 41 is turned on, and the movement of the jack 41 can drive the loading and unloading plate 3 to move up and down inside the test cylinder 1.

[0052] In this embodiment, the jack 41 replaces the tedious steps of unscrewing and disassembling the test block, greatly improving the time for loading and unloading the test block, reducing labor input, and increasing work efficiency. At the same time, this design reduces the risk of damage to the testing machine caused by frequent disassembly and improves operational safety.

[0053] In some embodiments of this disclosure, the loading and unloading device has a loading state; in the loading state, the drive assembly 4 drives the loading and unloading tray 3 to move to the discharge port 12. Specifically, when the loading and unloading device is in the loading state, and it is necessary to put the test block into the test cylinder 1, the specific operation is as follows: adjust the drive assembly 4, the drive assembly 4 drives the loading and unloading tray 3 to move, the loading and unloading tray 3 moves to the discharge port 12, and the test block is placed on the loading and unloading tray 3.

[0054] In some embodiments of this disclosure, the loading and unloading device has a detection state; in the detection state, the loading and unloading disc 3 is located at the first opening 11 under the drive of the drive assembly 4. Specifically, when it is necessary to drive the test block to the detection state (at this time the test block is located on the loading and unloading disc 3), the drive assembly 4 is adjusted, the drive assembly 4 drives the loading and unloading disc 3 to move, the drive assembly 4 drives the loading and unloading disc 3 to move inside the test cylinder 1, the loading and unloading disc 3 drives the test block on it to move inside the test cylinder 1, when the test block moves to the detection position inside the test cylinder 1, the drive assembly 4 is paused, at this time the loading and unloading device is in the detection state, and the detection liquid is introduced into the water inlet 31 to realize the performance detection of the test block.

[0055] In some embodiments of this disclosure, see Figure 5 , Figure 6 The loading and unloading tray 3 has a barrier 32; the barrier 32 and the loading and unloading tray 3 form a limiting space for the test block. In this embodiment, the barrier 32 ensures that the test block is always in a stable position on the loading and unloading tray 3, preventing the test block from slipping when the loading and unloading tray 3 moves inside the test cylinder 1, which would affect the test block's detection quality.

[0056] In some embodiments of this disclosure, see Figure 5 , Figure 6The loading and unloading device also includes a fixing rod 33; the fixing rod 33 is disposed inside the loading and unloading tray 3 so that a gap is formed between the bottom of the test block and the bottom of the loading and unloading tray 3. It can be understood that when the test block is placed inside the loading and unloading tray 3, the bottom of the test block is in contact with the loading and unloading tray 3, which makes it difficult or impossible for the test liquid to contact the bottom of the test block. Therefore, the fixing rod 33 can form a gap between the bottom of the test block and the loading and unloading tray 3, so that the test liquid can contact the bottom of the test block, thereby realizing the detection of the entire test block and improving the accuracy of the test block detection.

[0057] In some embodiments of this disclosure, the loading / unloading tray 3 is made of steel. In these embodiments, using steel for the loading / unloading tray 3 can reduce the corrosion of the loading / unloading tray 3 by the detection liquid, thereby increasing the service life of the loading / unloading device.

[0058] In some embodiments of this disclosure, see Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The loading and unloading device also includes a sealing assembly 5; the sealing assembly 5 includes a sealing airbag 51, a sealing tube 52 and an air supply pump 53; the sealing airbag 51 is arranged around the outside of the loading and unloading tray 3; one end of the sealing tube 52 is connected to the sealing airbag 51; the other end of the sealing tube 52 is connected to the air supply pump 53.

[0059] In this embodiment of the disclosure, the sealing component 5 can seal the gap between the loading / unloading tray 3 and the test cylinder 1, thereby improving the accuracy of the test block detection.

[0060] Specifically, the loading and unloading device in this embodiment has a detection state and a movement state. In the movement state, there is a gap between the sealing airbag 51 and the side wall of the test cylinder 1, so that the sealing airbag 51 does not interfere with the side wall of the test cylinder 1 and does not hinder the lifting and lowering movement of the loading and unloading tray 3. In the detection state, the sealing airbag 51 is pressed against the side wall of the test cylinder 1. In this way, the sealing airbag 51 is inflated and pressed against the inner wall of the test cylinder 1, achieving a seal between the loading and unloading tray 3 and the test cylinder 1, which helps to improve the detection accuracy of the test block.

[0061] As an example, see Figure 3 , Figure 4The sealing assembly 5 also includes a moving motor 54, a moving screw 55, and a moving bracket 56. The moving bracket 56 is mounted on one side of the testing machine, and the moving screw 55 is rotatably connected to the moving bracket 56. The axis of the moving screw 55 is perpendicular to the direction of movement of the loading / unloading disc 3 within the test cylinder 1. The air pump 53 is threadedly connected to the moving screw 55 via a connecting block. Specifically, when it is necessary to inflate the sealing airbag 51 (at this time, the loading / unloading disc 3 is located at the bottom of the test cylinder 1, and the inflation port 511 of the sealing airbag 51 is opposite to the sealing tube 52), the moving motor 54 is turned on. The moving motor 54 drives the moving screw 55 to rotate, and the rotation of the moving screw 55 drives the air pump 53 to approach the inflation port 511 of the sealing airbag 51. The corresponding test cylinder 1 has a hole corresponding to the inflation port 511 of the sealing airbag 51. The sealing tube 52 contacts the inflation port 511 of the sealing airbag 51, and the air supply pump 53 is turned on to inflate the sealing airbag 51, thereby achieving a seal inside the test cylinder 1; or the sealing tube 52 contacts the inflation port 511 of the sealing airbag 51, and the air supply pump 53 is turned on. The air supply pump 53 extracts the gas inside the sealing airbag 51. After the gas in the sealing airbag 51 is completely extracted, the moving motor 54 is turned on. The moving motor 54 drives the moving screw 55 to rotate. The rotation of the moving screw 55 drives the air supply pump 53 away from the inflation port of the sealing airbag 51. After that, the drive assembly 4 can drive the loading and unloading tray 3 to move up and down inside the test cylinder 1.

[0062] It should be noted that, in this embodiment, the inflation and deflation of the sealing airbag 51 are performed using a point-controlled method, a technique well known to those skilled in the art, and will not be described in detail here.

[0063] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
