Description

Technical Field

[0001] The present invention belongs to the technical field of material testing, and particularly relates to a test and detection device for highway engineering raw materials. Background Art

[0002] Highway engineering refers to the work of surveying, measuring, designing, constructing, maintaining, managing, etc. of highway structures. There are also many types of raw materials used in highway engineering construction, such as cement, sand and gravel, coarse aggregate, mortar, fly ash, etc. Among them, cement is used more in highway construction. Before highway engineering construction, it is necessary to conduct pressure testing on the selected raw material cement. The pressure testing in the early stage is related to the quality of the final product of highway engineering construction. There are two testing standards for cement, namely compressive strength and flexural strength. The usual testing method is to put the cement blocks made in advance with raw materials into a pressure testing device for pressure testing;

[0003] In the field of test and detection of highway engineering raw materials, the processing of concrete specimens has always been a cumbersome and risky task. The loading and unloading process of concrete specimens mainly relies on manual operation. The concrete specimens themselves are quite heavy, which makes it easy to collide during the lifting, moving and placing processes. This may not only cause damage to the specimens, but also cause harm to the operators. In addition, it is difficult to ensure the accuracy of the placement of concrete specimens by manual operation, which directly affects the accuracy and reliability of subsequent testing. More complicatedly, when removing the concrete specimens after the test, since the test process may cause the specimens to break and shed slag, the removal process becomes time-consuming and difficult, further reducing the efficiency and accuracy of the overall testing process.

[0004] Based on this, the present invention designs a test and detection device for highway engineering raw materials to solve the above problems. Summary of the Invention

[0017] The bottom end of the second toothed rod is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the side of the bearing seat. The second toothed rod is slidably connected to the inner wall of the middle hole.

[0018] As a further description of the above technical solution:

[0019] The extrusion adjustment mechanism includes an air storage frame fixedly connected under the workbench. A piston plate is slidably connected to the inner wall of the air storage frame.

[0020] As a further description of the above technical solution:

[0026] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0027] 1. In the present invention, a workbench, a bearing seat, an extrusion column, a guiding frame, a first rack, a gear, and a second rack are adopted. By controlling the downward elongation of the hydraulic rod, the test pressing plate is driven to move downward synchronously. At the same time, the forward sliding of the guiding frame is accurately controlled by means of the extrusion column. During this process, the movement of the guiding frame further drives the first rack, and then the synchronous upward movement of the second rack, the connecting seat, and the bearing seat is controlled through gear transmission, so as to realize the automatic pushing and feeding of concrete specimens. When the extrusion column moves into the vertical section of the guiding frame, the test pressing plate continues to move downward to perform an accurate pressure test on the concrete specimen. The feeding process is synchronized with the operation of the test pressing plate, realizing the automatic lifting and subsequent lowering of the concrete specimen, greatly improving the operation efficiency. The feeding and discharging processes of this device are fast, and there is no need for manual handling at all, which not only greatly reduces the work intensity of the operator, but also significantly reduces the risk of damage to the specimen during handling. In addition, the automatic processing ensures the high efficiency and accuracy of the compressive strength detection process of concrete specimens.

[0028] 2. In the present invention, a contact rod, a gas storage frame, an elastic telescopic air cylinder, a moving clamp seat and a rotating roller are adopted. When the connecting plate moves, the contact rod will be synchronously extruded, triggering the gas in the gas storage frame to be transferred to the elastic telescopic air cylinder through the extrusion plate. As the air pressure inside the air cylinder increases, it automatically extends, thereby precisely controlling the movement of the moving clamp seat and the rotating roller. This series of linkage actions ensures the precise contact between the rotating roller and the concrete specimen. At the same time, the moving clamp seat pushes the specimen to the center position of the bearing seat stably from four directions. Particularly, during the process of the test pressing plate moving down for testing, the concrete specimen can automatically adjust to the center position, ensuring the accuracy of the feeding process.

[0029] 3. In the present invention, a feeding table and a storage box are adopted. The operator only needs to place the concrete specimen on the front side of the feeding table, and then gently push the specimen to make it move smoothly backward onto the bearing seat, realizing the rapid and accurate feeding of the specimen. After the test is completed, the concrete specimen on the bearing plate and its fallen residues can be pushed into the rear storage box together by using a special tool. This design not only ensures the smooth progress of the specimen pushing process, but also makes the final removal process extremely fast and efficient. Through the ingenious design of this device, the processing flow of the concrete specimen is greatly simplified, effectively improving the working efficiency of the test and detection.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] Please refer to the attached Figure 1 - attached Figure 8, the present invention provides a technical solution: a test and detection device for highway engineering raw materials, including a workbench 1, a controller 3 is provided on the workbench 1, two support rods 4 are connected to the workbench 1, a top plate 5 is installed outside the support rods 4, a hydraulic rod 6 is installed through the top plate 5, the bottom end of the hydraulic rod 6 is fixedly connected to a test pressing plate 7, both the left and right sides of the test pressing plate 7 are connected with a moving adjustment mechanism 8, the moving adjustment mechanism 8 is installed on the workbench 1, a lifting adjustment mechanism 9 connected to the workbench 1 is provided under the moving adjustment mechanism 8, a bearing seat 10 is connected between the two lifting adjustment mechanisms 9, a middle hole 15 is opened at the position of the workbench 1 corresponding to the bearing seat 10, two extrusion adjustment mechanisms 11 are connected under the workbench 1, two pushing adjustment mechanisms 12 are connected to both the workbench 1 and the bearing seat 10, a first connecting pipe 13 is communicated between the left extrusion adjustment mechanism 11 and the two lower pushing adjustment mechanisms 12, and a second connecting pipe 14 is communicated between the right extrusion adjustment mechanism 11 and the two upper pushing adjustment mechanisms 12.

[0042] The hydraulic rod 6 applies a certain pressure to the concrete specimen through the test pressing plate 7 to achieve the compressive test of the concrete specimen.

[0043] Specifically, as Figure 1-2 shown, a loading table 16 is connected under the workbench 1, the position of the loading table 16 corresponds to the position of the bearing seat 10, four support legs 2 are fixedly connected under the workbench 1, a storage box 17 is installed under the workbench 1, and the storage box 17 is slidably connected to the back of the bearing seat 10.

[0044] Specifically, as Figure 3-4 shown, the moving adjustment mechanism 8 includes an extrusion column 81 fixedly connected to the side of the test pressing plate 7, a guide frame 82 is slidably connected outside the extrusion column 81, a sliding block 83 is fixedly connected to the side of the guide frame 82 away from the test pressing plate 7, a sliding frame 84 is slidably connected outside the sliding block 83, and a fixed rod 85 is fixedly connected to the outside of the sliding frame 84.

[0045] The fixed rod 85 is fixedly connected to the workbench 1, the guide frame 82 is composed of an inclined section and a vertical section, a first toothed rod 86 is connected to the bottom of the vertical section of the guide frame 82, and the first toothed rod 86 is arranged on the lifting adjustment mechanism 9.

[0046] During the movement of the test pressing plate 7, the guide frame 82 is extruded to move through the extrusion column 81. When the extrusion column 81 moves in the inclined section of the guide frame 82, the horizontal movement of the guide frame 82 can be controlled to realize the movement control of the first toothed rod 86. When the extrusion column 81 moves to the vertical section, at this time, the test pressing plate 7 continues to move down to press the concrete specimen, and the guide frame 82 and the first toothed rod 86 remain stable at this time. The sliding block 83 and the sliding frame 84 guide the front and back movement of the first toothed rod 86 and the guide frame 82 to ensure the stable and smooth movement of the guide frame 82.

[0047] Specifically, as Figure 4 shown, the lifting adjustment mechanism 9 includes a gear 91, the gear 91 meshes with the first rack 86, a connecting shaft 92 penetrates through the side of the gear 91, a bearing seat 93 is sleeved outside the connecting shaft 92, the bearing seat 93 is fixedly installed on the workbench 1, and the gear 91 externally meshes with a second rack 94.

[0048] The bottom end of the second rack 94 is fixedly connected with a connecting plate 95, the connecting plate 95 is fixedly connected to the side of the bearing seat 10, and the second rack 94 is slidably connected to the inner wall of the middle hole 15.

[0049] The bearing seat 93 positions the connecting shaft 92 and the gear 91, enabling the gear 91 to rotate stably and maintaining a stable meshing state with the first rack 86 and the second rack 94. By using the rotation of the gear 91 to control the upward movement of the second rack 94, since the second rack 94 stably slides in the middle hole 15 in the vertical direction, the second rack 94 can stably perform vertical actions, and the second rack 94 and the bearing seat 10 perform stable vertical movement.

[0050] Specifically, as Figure 5-7 shown, the extrusion adjustment mechanism 11 includes an air storage frame 111 fixedly connected under the workbench 1, a piston plate 112 is slidably connected to the inner wall of the air storage frame 111, a contact rod 113 is fixedly connected under the piston plate 112, and the contact rod 113 is located on the movement track of the connecting plate 95.

[0051] The contact rod 113 penetrates and is slidably connected to the lower side of the air storage frame 111, an elastic component 114 is fixedly connected to the piston plate 112, the elastic component 114 is arranged on the inner wall of the air storage frame 111, the left air storage frame 111 is communicated with the first connecting pipe 13, and the right air storage frame 111 is communicated with the second connecting pipe 14.

[0052] When the connecting plate 95 moves, it will squeeze the contact rod 113 to move. When the contact rod 113 moves, it will transfer the gas in the air storage frame 111 to the elastic telescopic air cylinder 121 through the extrusion plate. The elastic component 114 is used to control the downward reset of the piston plate 112 after the contact rod 113 is separated from the connecting plate 95. At the same time, the elastic force of the elastic component 114 can ensure that the piston plate 112 will not shake randomly.

[0053] Specifically, as Figure 5-6 and Figure 8As shown in the figure, the pushing and adjusting mechanism 12 includes an elastic telescopic air cylinder 121. One end of the elastic telescopic air cylinder 121 away from the test pressing plate 7 is fixedly connected with a fixed seat 122. The lower fixed seat 122 is fixedly connected to the bearing seat 10, and the upper fixed seat 122 is fixedly connected to the workbench 1. The four elastic telescopic air cylinders 121 are respectively located in the front, back, left, and right of the test pressing plate 7. The lower elastic telescopic air cylinder 121 is communicated with the first connecting pipe 13, and the upper elastic telescopic air cylinder 121 is communicated with the second connecting pipe 14.

[0054] The telescopic end of the elastic telescopic air cylinder 121 is fixedly connected with a moving clamp seat 123, and a rotating roller 124 is rotatably connected to the inner wall of the moving clamp seat 123.

[0055] The rotating roller 124 ensures that the friction between the rotating roller 124 and the concrete specimen is small during the process of the moving clamp seat 123 moving to push the concrete specimen, and the concrete specimen can move smoothly.

[0056] When the internal air pressure of the elastic telescopic air cylinder 121 increases, it will automatically extend. When the elastic telescopic air cylinder 121 extends, it will control the movement of the moving clamp seat 123 and the rotating roller 124 until the rotating roller 124 contacts the concrete specimen. The moving clamp seat 123 pushes the concrete specimen to the middle position of the bearing seat 10 from four directions, and the contact rod 113 and the connecting plate 95 are separated. At this time, the elastic telescopic air cylinder 121 automatically resets by elasticity, and the gas is squeezed into the air storage frame 111, realizing the separation between the moving clamp seat 123 and the rotating roller 124 and the concrete specimen.

[0057] Working principle: When in use:

[0058] When it is necessary to conduct a compressive test on the concrete, directly place the concrete specimen on the front side of the feeding table 16, and then push the concrete specimen backward to the bearing seat 10. At this time, control the hydraulic rod 6 to extend downward. While the test pressing plate 7 moves downward, it controls the guide frame 82 to slide forward through the extrusion column 81. While the guide frame 82 moves, it controls the gear 91 to rotate through the first rack 86. The gear 91 controls the second rack 94, the connecting seat, and the bearing seat 10 to move upward, realizing the automatic upward feeding of the concrete specimen. While the connecting plate 95 moves, it will squeeze the contact rod 113 to move. While the contact rod 113 acts, it will squeeze and transfer the gas in the air storage frame 111 to the elastic telescopic air cylinder 121 through the extrusion plate. When the internal air pressure of the elastic telescopic air cylinder 121 increases, it will automatically extend. When the elastic telescopic air cylinder 121 extends, it will control the movement of the moving clamp seat 123 and the rotating roller 124 until the rotating roller 124 contacts the concrete specimen. The moving clamp seat 123 pushes the concrete specimen to the middle position of the bearing seat 10 from four directions, and the position of the concrete specimen corresponds to that of the test pressing plate 7;

[0059] When the extrusion column 81 moves into the vertical section of the guiding frame 82, the test pressure plate 7 continues to move downward to conduct a pressure test on the concrete specimen. At the same time, the guiding frame 82, the bearing plate, and the concrete specimen remain stable. The test results can be viewed through the controller 3. After the test is completed, the hydraulic rod 6 is controlled to shorten, and the test pressure plate 7 moves upward and separates from the concrete specimen. At the same time, the extrusion column 81 controls the guiding frame 82 to move backward. When the guiding frame 82 and the first toothed rod 86 move backward, the bearing plate and the concrete specimen after being extruded and tested are controlled to move downward. At the same time, the contact rod 113 separates from the connecting plate 95. At this time, the elastic telescopic air cylinder 121 automatically resets by elasticity, and the gas is extruded into the air storage frame 111, realizing the separation between the movable clamp seat 123 and the rotating roller 124 and the concrete specimen. When the position of the bearing plate corresponds to that of the storage box 17, the hydraulic rod 6 is controlled to stop working. At this time, a tool is used to push the concrete specimen and the fallen residues on the bearing plate backward and drop them into the storage box 17.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
