Description

Technical Field

[0001] This utility model belongs to the field of cement setting detection technology, specifically, it relates to a cement setting detection device. Background Technology

[0002] In the field of cement production and quality testing, cement setting time is one of the core indicators for measuring cement performance. It is directly related to the workability and final strength of cement products. The determination of cement setting time requires precise control of the time point from the addition of water and mixing to the point where cement loses its plasticity and begins to harden. This data is not only a key basis for cement factory inspection, but also an important reference for the rational arrangement of pouring, vibration and other processes in construction projects. Therefore, it is necessary to use testing equipment to determine cement setting time to ensure the quality of cement products and the safety of construction projects.

[0003] Existing cement setting testing devices have been found to have uneven needle drop distribution during testing. Relying on the operator to move the glass slide may result in repeated needle drops into the same hole, causing the test results to fail to fully and accurately reflect the cement setting state, thus affecting testing efficiency and the accuracy of test data.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the problems of uneven needle distribution in existing cement setting testing devices, where operators manually adjust the glass slide position, potentially causing needles to repeatedly fall into the same hole, resulting in incomplete and inaccurate results reflecting the cement setting state and impacting testing efficiency and data accuracy, the basic concept of this invention is as follows:

[0006] A cement setting test device includes a base, a support, and a test seat. The support is slidably mounted on the base, and the test seat is connected to the end of the support. An installation cavity is formed in the base, and two support rods are installed in the installation cavity. A rotating shaft is rotatably mounted on the two support rods, and a cam is mounted on the rotating shaft. A rotating disk is rotatably mounted on the rotating shaft, and a plurality of rollers are evenly distributed on the bottom of the rotating disk. The rollers are adapted to the cam.

[0007] In a preferred embodiment of this utility model, a lifting rod is slidably installed in the detection seat, and a detection needle is installed at the end of the lifting rod.

[0008] In a preferred embodiment of this utility model, a scale plate is connected to the detection seat.

[0009] In a preferred embodiment of this utility model, the base is provided with a sliding groove, the bottom of the bracket is slidably installed in the sliding groove, the side wall of the base is provided with a through groove, a locking nut is installed in the through groove, the locking nut is engaged with the bracket, the sliding groove and the through groove are interconnected, and the locking nut passes through the through groove.

[0010] In a preferred embodiment of this utility model, the rotating disk passes through the upper surface of the base, and a placement plate is connected to the rotating disk, with a slot provided on the placement plate.

[0011] In a preferred embodiment of this utility model, the rotating shaft passes through the side wall of the base, and a knob is connected to the end of the rotating shaft.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention uses a knob to drive a rotating shaft, which in turn drives a cam roller to drive a rotating disk, causing the detection needle to move around the center of the test mold cover. This avoids repeated testing and ensures that the detection points are evenly distributed. The distance between the test mold cover and the detection needle can be flexibly adjusted by combining a sliding bracket and a locking nut. The operation is simple and significantly improves the detection efficiency and practicality of the device.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 4 As shown, a cement setting test device includes a base 1, a support 11, and a test seat 14. The support 11 is slidably mounted on the base 1, and the test seat 14 is connected to the end of the support 11. An installation cavity 2 is formed in the base 1, and two support rods 3 are installed in the installation cavity 2. A rotating shaft 4 is rotatably mounted on the two support rods 3, and a cam 5 is mounted on the rotating shaft 4. A rotating shaft 6 is installed in the installation cavity 2, and a rotating disk 7 is rotatably mounted on the rotating shaft 6. Several rollers 8 are evenly distributed at the bottom of the rotating disk 7, and the rollers 8 are adapted to the cams 5. In this configuration, the base 1 provides support for the device, the support 11 supports the test seat 14, and the support rods 3 support the rotation of the rotating shaft 4 within the installation cavity 2 of the base 1. The cams 5 on the rotating shaft 4 cooperate with the rollers 8 at the bottom of the rotating disk 7. When the rotating shaft 4 rotates, the cams 5 drive the rotating disk 7 to rotate around the rotating shaft 6 through the rollers 8, thereby changing the test position each time.

[0023] like Figures 1 to 4 As shown, in a specific embodiment, a lifting rod 15 is slidably installed in the detection seat 14, and a detection needle is installed at the end of the lifting rod 15. In this configuration, the lifting rod 15 in the detection seat 14 can slide up and down, and the detection needle at the end is used to penetrate the cement sample to detect the setting state.

[0024] like Figures 1 to 4 As shown, a scale plate is further connected to the detection base 14. In this configuration, the scale plate is mounted on the detection base 14 to assist in reading the displacement of the lifting rod 15 and accurately control the insertion depth of the detection needle.

[0025] like Figures 1 to 4 As shown, further, a sliding groove 10 is provided on the base 1, and the bottom of the bracket 11 is slidably installed in the sliding groove 10. A through groove 12 is provided on the side wall of the base 1, and a locking nut 13 is installed in the through groove 12. The locking nut 13 engages with the bracket 11. The sliding groove 10 and the through groove 12 are interconnected, and the locking nut 13 passes through the through groove 12. In this configuration, the sliding groove 10 and the through groove 12 are interconnected, and the locking nut 13 passes through the through groove 12 and fixes the bracket 11. When tightened, it can ensure that the bracket 11 does not shift during testing, allowing the operator to change the distance between the axis of the test mold cover and the axis of the testing needle by changing the position of the bracket 11, thereby adjusting the distance between the testing hole and the center of the test mold cover.

[0026] like Figures 1 to 4As shown, further, the rotating disk 7 passes through the upper surface of the base 1, and a placement plate 9 is connected to the rotating disk 7. The placement plate 9 is provided with a slot. In this configuration, the rotating disk 7 passes through the upper surface of the base 1, and the connected placement plate 9 fixes the glass slide and the test mold cover through the slot. When the rotating disk 7 rotates, it drives the sample to rotate synchronously, so that the detection needle detects evenly with the center of the test mold cover as the center, avoiding the detection needle from falling into the original needle hole.

[0027] like Figures 1 to 4 As shown, further, the rotating shaft 4 passes through the side wall of the base 1, and a knob 16 is connected to the end of the rotating shaft 4. In this configuration, the knob 16 is connected to the end of the rotating shaft 4, and the operator drives the entire transmission system by rotating the knob 16. The cooperation between the cam 5 and the roller 8 converts the rotational motion into the rotation of the rotating disk 7.

[0028] The implementation principle of the cement setting test device in this embodiment is as follows: In use, the operator first places the base 1 on the test bench, places the mold cover in the center of the glass slide (the glass slide has a pattern corresponding to the mold cover, facilitating placement), then pours the cement sample into the mold cover, and finally places the glass slide in the slot of the placement plate 9. The initial test is then performed using the test seat 14, lifting rod 15, and test needle (this part of the test operation is prior art). When a second test is required, the operator rotates the knob 16, which drives the rotating shaft 4 to rotate on the support rod 3, thereby causing the rotating shaft 4 to... The cam 5 rotates, and the cam 5 cooperates with the roller 8 to drive the rotating disk 7 to rotate around the rotating shaft 6 at a certain angle. The rotating disk 7 drives the placement plate 9 to rotate, and the glass plate and the test mold cover on the placement plate 9 rotate accordingly. This enables the test needle to perform circular testing with the center of the test mold cover as the center and the distance between the test mold cover and the test needle as the radius, avoiding the test needle from falling into the original needle hole and making the testing more uniform. In addition, by changing the position of the bracket 11 in the slide groove 10, the distance between the axis of the test mold cover and the axis of the test needle can be changed, thereby adjusting the distance between the test hole and the center of the test mold cover. After the adjustment is completed, the position of the bracket 11 is fixed by locking the nut 13.
