Description

Technical Field

[0001] This utility model relates to the field of concrete curing agent testing technology, and in particular to a concrete curing agent performance testing device. Background Technology

[0002] Concrete curing agents are key materials for improving the durability and strength development of concrete. They inhibit moisture evaporation through film formation or penetration, ensuring full cement hydration. The performance of concrete curing agents is affected by various factors, among which pH value is a crucial indicator. Excessively high or low pH values ​​can lead to corrosion and cracking on the concrete surface, reducing its service life. Therefore, pH value is one of the core indicators for evaluating the chemical stability of concrete curing agents and their effectiveness in protecting concrete from alkalinity. pH meters are often used to test the pH value of concrete curing agents.

[0003] However, when using existing pH meter-type testing devices to test the pH value of concrete curing agents, after placing the lower end of the measuring electrode in the concrete curing agent, in order to ensure the uniformity of the concrete curing agent and obtain accurate and stable pH measurement results, the testing personnel need to manually shake the test cup to eliminate the unevenness of the concrete curing agent. However, manually shaking the test cup is not only physically demanding, but also requires the testing personnel to pay close attention to avoid the lower end of the measuring electrode colliding with the inner wall of the test cup, thus reducing the convenience of using pH meter-type testing devices. Utility Model Content

[0004] This utility model relates to a concrete curing agent performance testing device. Through the setting of a shaking mechanism, the test cup is automatically shaken horizontally during testing, so that the concrete curing agent is more evenly distributed. It does not require manual shaking, which not only saves physical strength, but also eliminates the risk of collision between the lower end of the measuring electrode and the inner wall of the test cup. The testing personnel do not need to pay attention at all times, which improves the convenience of using this testing device.

[0005] In a first aspect, this utility model provides a concrete curing agent performance testing device, specifically comprising: a base plate, a square guide rod fixedly connected to the rear side of the upper surface of the base plate, and an electrode bracket slidably connected to the square guide rod; an angle adjustment mechanism is provided on the left side of the upper surface of the base plate, and a pH meter host is provided on the angle adjustment mechanism, the pH meter host is connected to a measuring electrode via a wire, and the measuring electrode is mounted on the electrode bracket; a shaking mechanism is provided on the right side of the upper surface of the base plate, and a clamping mechanism is installed on the top of the shaking mechanism, with a test cup clamped on the clamping mechanism.

[0006] Furthermore, the electrode support is connected by a threaded hand-tightening bolt, which is used to fix the electrode support; a controller is installed on the front left side of the upper upper surface of the base plate.

[0007] Furthermore, the angle adjustment mechanism includes a rotating shaft and an angle adjustment motor. The rotating shaft is rotatably connected to the upper surface of the base plate and is fixedly connected to the bottom of the pH meter main unit. A worm gear is fixedly installed on the left end of the rotating shaft. The angle adjustment motor is fixedly installed on the upper surface of the base plate, and a worm gear that meshes with the worm gear is fixedly connected to the rotating shaft of the angle adjustment motor.

[0008] Furthermore, the shaking mechanism includes a fixed plate, which is fixedly installed on the right side of the upper surface of the base plate. Four support columns are fixedly connected to the upper surface of the fixed plate, and a universal ball bearing is installed at the upper end of each support column. The top of the universal balls on the four universal ball bearings are rotatably connected to the shaking plate. A tension spring is fixedly connected to each of the four corners of the bottom surface of the shaking plate, and the lower ends of the four tension springs are respectively fixedly connected to the four corners of the upper surface of the fixed plate. A drive motor is fixedly installed in the middle of the upper surface of the fixed plate, and a circular drive plate is fixedly installed on the upper end of the drive motor shaft. A drive shaft is fixedly connected to the edge of the upper surface of the circular drive plate, and a rotating cylinder is rotatably connected to the outside of the drive shaft. The rotating cylinder is fixedly connected to the center of the bottom surface of the shaking plate.

[0009] Furthermore, the clamping mechanism includes a circular base, which is fixedly connected to the middle of the upper surface of the rocking plate. The upper surface of the circular base has two sliding grooves, and a sliding block is slidably connected inside each sliding groove.

The clamping screw has two reverse threads arranged symmetrically on the outside, and two nuts are connected to the outside of the clamping screw through the two reverse threads. The two nuts are fixedly connected to the lower ends of the two sliding blocks respectively.

[0010] This utility model provides a device for testing the performance of concrete curing agents, which has the following beneficial effects:

[0011] 1. By setting up a shaking mechanism, during the testing process, the drive motor can be started to rotate the circular drive plate, which in turn drives the shaft to rotate. The rotating shaft then drives the rotating cylinder and the shaking plate to shake horizontally, thereby causing the clamping mechanism and the test cup to shake horizontally. This makes the concrete curing agent in the test cup more uniform, and eliminates the need for manual shaking, saving physical effort. Furthermore, because the horizontal shaking range of the shaking plate is fixed, it eliminates the risk of the lower end of the measuring electrode colliding with the inner wall of the test cup, thus eliminating the need for the testing personnel to pay constant attention. Therefore, this improves the convenience of using this testing device.

[0012] 2. The angle adjustment mechanism allows the pH meter's main unit angle to be adjusted according to the height of the testing personnel. During adjustment, the controller simply controls the rotation of the angle adjustment motor shaft in both directions, which in turn rotates the worm gear, worm wheel, and rotating shaft in both directions, ultimately adjusting the angle of the pH meter's main unit. This makes it easier for the testing personnel to observe the values ​​displayed on the pH meter's main unit screen, greatly improving the convenience of the testing process and the accuracy of data reading.

The top of the moving mechanism 4 is equipped with a clamping mechanism 5, which clamps a test cup 6. A hand-tightening bolt 103 is threadedly connected to the electrode support 102 for fixing the electrode support 102. A controller 104 is installed on the front left side of the upper end face of the base plate 1. The shaking mechanism 4 includes a fixing plate 401, which is fixedly installed on the right side of the upper end face of the base plate 1. Four support columns 402 are fixedly connected to the upper end face of the fixing plate 401, and a universal ball bearing is installed at the upper end of each support column 402. 403, four universal ball bearings 403 have rolling connections to the top of their universal balls, with a wobbling plate 404 attached. A tension spring 406 is fixedly connected to each of the four corners of the bottom surface of the wobbling plate 404, and the lower ends of the four tension springs 406 are fixedly connected to the four corners of the upper surface of the fixed plate 401. A drive motor 405 is fixedly mounted in the middle of the upper surface of the fixed plate 401, and a circular drive plate 407 is fixedly mounted on the upper end of the shaft of the drive motor 405. A drive shaft is fixedly connected to the edge of the upper surface of the circular drive plate 407. 408, the rotating shaft 408 is externally connected to a rotating cylinder 409, and the rotating cylinder 409 is fixedly connected to the center of the bottom end face of the shaking plate 404; through the setting of the shaking mechanism 4, the clamping mechanism 5 and the test cup 6 can be horizontally shaken during the testing process, so that the concrete curing agent in the test cup 6 is more uniform, and no manual shaking is required, which not only saves physical strength, but also eliminates the risk of collision between the lower end of the measuring electrode 301 and the inner wall of the test cup 6 because the horizontal shaking range of the shaking plate 404 is fixed.

[0030] The clamping mechanism 5 includes a circular base 501, which is fixedly connected to the middle of the upper surface of the shaking plate 404. Two sliding grooves 502 are formed on the upper surface of the circular base 501. A sliding block 503 is slidably connected inside each sliding groove 502. A clamping plate 504 is fixedly connected to the opposite surfaces of the two sliding blocks 503. An arc-shaped clamping opening is formed in the middle of the opposite surfaces of the two clamping plates 504, and an anti-slip film 506 is pasted inside each arc-shaped clamping opening. A rectangular groove 507 communicating with the sliding grooves 502 is formed in the middle of the bottom surface of the circular base 501. A clamping screw 505 is rotatably connected inside the rectangular groove 507. The clamping screw 505 has two reverse threads arranged symmetrically on its exterior, and two nuts 508 are connected to the exterior of the clamping screw 505 through the two reverse threads. The two nuts 508 are fixedly connected to the lower ends of the two sliding blocks 503 respectively. The clamping mechanism 5 is used to clamp and position the test cup 6.

[0031] Example 2, based on Example 1, such as Figure 1 and Figure 3 As shown, the angle adjustment mechanism 2 includes a rotating shaft 201 and an angle adjustment motor 203. The rotating shaft 201 is rotatably connected to the upper surface of the base plate 1 and is fixedly connected to the bottom of the pH meter main unit 3. A worm gear 202 is fixedly installed on the left end of the rotating shaft 201. The angle adjustment motor 203 is fixedly installed on the upper surface of the base plate 1, and a worm 204 that meshes with the worm gear 202 is fixedly connected to the rotating shaft of the angle adjustment motor 203. The angle adjustment motor 203 and the drive motor 405 are both electrically connected to the controller 104. By setting the angle adjustment mechanism 2, the angle of the pH meter main unit 3 can be adjusted according to the height of the testing personnel, which is beneficial for the testing personnel to observe the values ​​displayed on the display screen of the pH meter main unit 3.

[0032] The working principle of this embodiment is as follows: When in use, the concrete curing agent to be tested is first poured into the test cup 6. Then, the test cup 6 is clamped and fixed to the upper part of the circular base 501. When clamping, the test cup 6 is placed on the middle side of the upper part of the circular base 501. Then, by manually rotating the clamping screw 505, the two nuts 508 move in opposite directions at the two opposite threads on the outside of the clamping screw 505, thereby clamping and fixing the test cup 6 through the two clamping plates 504.

[0033] Then loosen the hand-tightening bolt 103, slide the electrode bracket 102 downwards, and slide the measuring electrode 301 up and down, so that the lower end of the measuring electrode 301 is inserted into the concrete curing agent. Then, the controller 104 starts the drive motor 405, which rotates the circular drive plate 407. Then, the circular drive plate 407 drives the drive shaft 408 to rotate. The rotating drive shaft 408 drives the rotating cylinder 409 and the shaking plate 404 to shake horizontally, thereby causing the clamping mechanism 5 and the test cup 6 to shake horizontally. Therefore, the concrete curing agent in the test cup 6 is more uniform, and no manual shaking is required. This not only saves physical strength, but also avoids the lower end of the measuring electrode 301 from colliding with the inner wall of the test cup 6 because the horizontal shaking range of the shaking plate 404 is fixed.

[0034] Then, the pH value of the concrete curing agent in the test cup 6 is detected by measuring electrode 301 and pH meter host 3. When the tester needs to observe the value displayed on the display screen of pH meter host 3, the rotation of the shaft of angle adjustment motor 203 can be controlled by controller 104 to rotate forward and reverse, thereby causing worm 204, worm wheel 202 and rotating shaft 201 to rotate forward and reverse, which can ultimately adjust the angle of pH meter host 3, thus making it easier for the tester to observe the value displayed on the display screen of pH meter host 3.
