Description

Technical Field

[0001] This utility model relates to the field of cement testing technology, and in particular to an electric flexural strength testing machine for cement testing. Background Technology

[0002] Cement products are products made by using cement as the main binder, combined with aggregates such as sand, gravel, and steel bars, and manufactured through prefabrication or cast-in-place processes. They are widely used in construction, municipal engineering, transportation, and other fields, covering a wide range of types, including cement pipes (such as water pipes and drainage pipes), cement poles and columns (such as utility poles and piles), bridge components (such as highway and railway bridge components), cement bricks (such as paving bricks and decorative bricks), cement tiles (such as flat tiles and ridge tiles), and cement boards (such as hollow boards and sandwich panels). They play important roles in supporting, protecting, and decorating in different scenarios.

[0003] In the production process of cement products, flexural strength testing is required, necessitating the use of a flexural testing machine. Current flexural testing methods typically involve placing the specimen on top of a lower clamp, then lowering an upper clamp via a hydraulic rod to apply load. However, due to the initial distance between the hydraulic rod and the upper clamp, load counting begins before the hydraulic rod contacts the upper clamp, severely impacting the accuracy of the test data. Furthermore, the loading rollers are often installed using bolts, a simple but time-consuming method that significantly reduces work efficiency when the loading rollers are damaged and need replacement. Therefore, this application proposes an electric flexural testing machine for cement testing to meet these requirements. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies, such as inaccurate test data and long replacement time of loading rollers, this utility model provides an electric flexural strength testing machine for cement testing.

[0005] The technical implementation scheme of this utility model is as follows: an electric flexural strength testing machine for cement testing includes an operating table, a mounting base fixedly connected to the top of the operating table, mounting frames fixedly connected to both sides of the mounting base on the top of the operating table, a hydraulic rod mounted on the top of the mounting frame, a pressure block fixedly connected to the bottom of the hydraulic rod, an upper clamp mounted on the top of the mounting base at the bottom of the pressure block, a loading roller mounted at the bottom of the upper clamp, an installation component mounted at the connection between the loading roller and the upper clamp, a lower clamp mounted below the upper clamp, and a lifting component mounted between the lower clamp and the mounting frame.

[0006] Optionally, the mounting assembly includes a mounting groove, a mounting block, a mounting hole, a through groove, and a mounting rod. The mounting groove is formed at the bottom of the upper clamp. The mounting block is fixedly connected to the top of the loading roller and is adapted to the size of the mounting groove. The mounting hole passes through the mounting block. The through groove passes through the inner wall of one side of the mounting groove. The mounting rod is slidably connected to the through groove and is adapted to the size of the mounting hole.

[0007] Optionally, the mounting assembly further includes a slide groove, a slider, a spring, and a pull block. The slide groove is formed on the inner wall of the through groove. The slider is fixedly connected to the outer periphery of the mounting rod and slidably connected to the slide groove. The spring is sleeved on the outer periphery of the mounting rod and its two ends are respectively fixedly connected to the inner wall of the slider on the side away from the mounting groove and the slide groove on the side away from the mounting groove. The pull block is fixedly connected to the outer end of the mounting rod.

[0008] Optionally, the lifting assembly includes a lifting groove, a lifting block, and a screw. The lifting groove is formed on the inner walls of both sides of the mounting frame. The lifting block is fixedly connected to both sides of the lower clamp and slidably connected to the lifting groove. The top and bottom of the screw are rotatably connected to the inner walls of the top and bottom of the lifting groove, respectively. The screw passes through and is threadedly connected to the lifting block.

[0009] Optionally, the lifting assembly further includes a rotating groove, a rotating rod, and a rotating block. The rotating groove extends through the inner wall of the bottom of the lifting groove and the operating platform. The rotating rod is rotatably connected to the rotating groove and fixedly connected to the bottom of the screw. The rotating block is fixedly connected to the bottom of a set of rotating rods.

[0010] Optionally, the lifting assembly further includes a drive wheel and a drive belt. The drive wheel is provided in two sets and is fixedly connected to the outer periphery of the two sets of rotating rods near the bottom. The drive belt is wrapped around the two sets of drive wheels.

[0011] This utility model has the following advantages:

[0012] 1. This utility model features an installation assembly. Pulling the pull block outward causes it to slide along the groove via the installation rod, compressing the spring. When the installation rod moves out of the installation hole, the loading roller moves downward, causing the installation block to move downward synchronously. When the installation block moves out of the installation groove, the loading roller can be disassembled. At this point, the installation block on the top of the new loading roller is placed in the installation groove, ensuring the installation hole and installation rod are on the same axis. Then, the pull block is released, the spring rebounds, and the installation rod moves inward via the slider. When the installation rod is inserted into the installation hole, the installation block is fixed in the installation groove, thus completing the installation of the new loading roller. This design allows for quick installation and disassembly of the loading roller, thereby improving the replacement efficiency when the loading roller is damaged.

[0013] 2. This utility model incorporates a lifting assembly. Rotating the rotating block causes a set of rotating rods to rotate along the rotating groove. Since the transmission wheel is fixedly connected to the outer circumference of the bottom of the rotating rod and the transmission belt is wrapped around the two sets of transmission wheels, the rotation of one set of rotating rods simultaneously drives the other set of rotating rods to rotate synchronously. The rotating rods, in turn, drive the screw to rotate synchronously. Because the screw passes through and is threadedly connected to the lifting block, the lifting block slides upward along the lifting groove as the screw rotates, thereby causing the lower clamp to rise. When the specimen is in close contact with the loading roller, stopping the rotation of the rotating block will maintain the specimen at its current height. When the specimen breaks, rotating the rotating block in the opposite direction will cause the lower clamp to move downward. When the specimen separates from the loading roller, the specimen can be removed. This design allows the specimen to be adjusted to be in close contact with the loading roller after placement, thus making the test data more accurate. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] An electric flexural strength testing machine for cement testing includes an operating table 1, a mounting base 2 fixedly connected to the top of the operating table 1, mounting frames 3 fixedly connected to both sides of the mounting base 2 on the top of the operating table 1, a hydraulic rod 4 mounted on the top of the mounting frame 3, a pressure block 5 fixedly connected to the bottom of the hydraulic rod 4, an upper clamp 6 mounted on the top of the mounting base 2 at the bottom of the pressure block 5, a loading roller 7 mounted at the bottom of the upper clamp 6, an installation component 8 mounted at the connection between the loading roller 7 and the upper clamp 6, a lower clamp 9 mounted below the upper clamp 6, and a lifting component 10 mounted between the lower clamp 9 and the mounting frame 3.

[0021] It should be noted that the mounting component 8 enables the loading roller 7 to be installed and removed quickly, thereby improving the replacement efficiency when it is damaged. The lifting component 10 enables the specimen to be adjusted to fit tightly with the loading roller 7 after it is placed, thereby making the test data more accurate.

[0022] like Figure 2 and Figure 3 As shown, the mounting assembly 8 includes a mounting groove 81, a mounting block 82, a mounting hole 83, a through groove 84, and a mounting rod 85. The mounting groove 81 is opened at the bottom of the upper clamp 6. The mounting block 82 is fixedly connected to the top of the loading roller 7 and is adapted to the size of the mounting groove 81. The mounting hole 83 passes through the mounting block 82. The through groove 84 passes through the inner wall of one side of the mounting groove 81. The mounting rod 85 is slidably connected to the through groove 84 and is adapted to the size of the mounting hole 83.

[0023] It should be noted that the mounting block 82 is placed in the mounting groove 81, and then the mounting rod 85 is inserted into the mounting hole 83. At this time, the mounting block 82 can be fixed in the mounting groove 81, thus completing the installation of the loading roller 7. The mounting rod 85 is removed from the mounting hole 83, and then the mounting block 82 is removed from the mounting groove 81. At this time, the disassembly of the loading roller 7 can be completed.

[0024] like Figure 2 As shown, the mounting assembly 8 also includes a slide groove 86, a slider 87, a spring 88, and a pull block 89. The slide groove 86 is formed in the inner wall of the through groove 84. The slider 87 is fixedly connected to the outer periphery of the mounting rod 85 and slidably connected to the slide groove 86. The spring 88 is sleeved on the outer periphery of the mounting rod 85 and its two ends are respectively fixedly connected to the inner wall of the slider 87 away from the mounting groove 81 and the slide groove 86 away from the mounting groove 81. The pull block 89 is fixedly connected to the outer end of the mounting rod 85.

[0025] It should be noted that pulling the pull block 89 outward will cause the slider 87 to slide outward along the slide groove 86 via the mounting rod 85, thus compressing the spring 88. Releasing the pull block 89 will cause the spring 88 to rebound, which will then cause the mounting rod 85 to move inward via the slider 87.

[0026] like Figure 4As shown, the lifting assembly 10 includes a lifting groove 101, a lifting block 102, and a screw 103. The lifting groove 101 is opened on the inner walls of both sides of the mounting frame 3. The lifting block 102 is fixedly connected to both sides of the lower clamp 9 and slidably connected to the lifting groove 101. The top and bottom of the screw 103 are rotatably connected to the inner walls of the top and bottom of the lifting groove 101, respectively. The screw 103 passes through and is threadedly connected to the lifting block 102.

[0027] It should be noted that since the screw 103 passes through and is threadedly connected to the lifting block 102, and since the lifting block 102 is slidably connected to the lifting groove 101, the lifting block 102 will slide up and down along the lifting groove 101 as the screw 103 rotates.

[0028] like Figure 4 As shown, the lifting assembly 10 also includes a rotating groove 104, a rotating rod 105, and a rotating block 106. The rotating groove 104 passes through the bottom inner wall of the lifting groove 101 and the operating table 1. The rotating rod 105 is rotatably connected to the rotating groove 104 and fixedly connected to the bottom of the screw 103. The rotating block 106 is fixedly connected to the bottom of a set of rotating rods 105.

[0029] It should be noted that rotating the rotating block 106 can drive the rotating rod 105 to rotate along the rotating groove 104, thereby driving the screw 103 to rotate synchronously.

[0030] like Figure 4 As shown, the lifting assembly 10 also includes a transmission wheel 107 and a transmission belt 108. The transmission wheel 107 is provided in two sets and is fixedly connected to the outer periphery of the two sets of rotating rods 105 near the bottom. The transmission belt 108 is wrapped around the two sets of transmission wheels 107.

[0031] It should be noted that since the transmission wheel 107 is fixedly connected to the bottom outer circumference of the rotating rod 105 and the transmission belt 108 is wrapped around the two sets of transmission wheels 107, the rotation of one set of rotating rods 105 will drive the other set of rotating rods 105 to rotate synchronously.

[0032] In a specific application scenario, the specimen to be tested is first placed on top of the lower clamp 9. Then, the rotating block 106 is rotated to drive a set of rotating rods 105 to rotate along the rotating groove 104. Since the transmission wheel 107 is fixedly connected to the outer circumference of the bottom of the rotating rod 105 and the transmission belt 108 is wrapped around the two sets of transmission wheels 107, the rotation of one set of rotating rods 105 will drive the other set of rotating rods 105 to rotate synchronously. The rotating rods 105 will then drive the screw 103 to rotate synchronously. Since the screw 103 is threaded through and connected to the lifting block 102, the lifting block 102 will slide upward along the lifting groove 101 as the screw 103 rotates, thereby driving the lower clamp 9 to rise. When the specimen is in close contact with the loading roller 7, the rotating block 106 is stopped and the hydraulic rod 4 is activated. The pressure block 5 drives the upper clamp 6 and the loading roller 7 to move downward and load the specimen. When the specimen breaks, the hydraulic rod 4 is closed and the rotating block is rotated in the opposite direction. 106 causes the lower clamp 9 to move downwards. When the specimen separates from the loading roller 7, the specimen can be removed. When the loading roller 7 is damaged and needs to be replaced, pull the pull block 89 outwards so that it drives the slider 87 to slide outwards along the slide groove 86 through the mounting rod 85 and squeeze the spring 88. When the mounting rod 85 moves out of the mounting hole 83, move the loading roller 7 downwards so that it drives the mounting block 82 to move downwards synchronously. When the mounting block 82 moves out of the mounting groove 81, the loading roller 7 can be disassembled. At this time, place the mounting block 82 on the top of the new loading roller 7 into the mounting groove 81 and make the mounting hole 83 and the mounting rod 85 on the same axis. Then release the pull block 89. The spring 88 rebounds and drives the mounting rod 85 to move inwards through the slider 87. When the mounting rod 85 is inserted into the mounting hole 83, the mounting block 82 can be fixed in the mounting groove 81, thus completing the installation of the new loading roller 7.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
