Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of detection device, concretely relates to a curing and setting time determination integrated device for cementing material. BACKGROUND

[0002] Cement, gypsum and other building materials as cementing material, its setting time will have a great influence on the construction. At present, the existing related standard has strong consistency to the test method of cement, gypsum and other cementing material initial setting time, that is, the determination material is injected into the mold for curing, then the sample is taken out and is judged by the artificial through the initial setting needle in the sample The depth of penetration, while the test method of final setting time is judged by the final setting needle touching the sample to observe the trace.

[0003] However, in the actual test operation process, the following defects and difficulties exist:

[0004] 1. Because the temperature and humidity requirements of the sample curing environment are high, the sample needs to be taken out from the curing environment for multiple times during the setting time determination, and then tested (that is, curing and testing are independent of each other), and the environment of the sample changes in the process, which will affect the result;

[0005] 2. For some fast-setting type plugging products, the sample setting time is extremely short, and the artificial testing may be in the process of putting the sample into the curing environment. The sample has already been finally set, and the testing needle needs to be replaced during testing, so the time is relatively tight, and the testing result is easy to have a large error. SUMMARY

[0006] The utility model wants to solve the technical problem of overcoming the shortage of prior art, and provides a new curing and setting time determination integrated device for cementing material.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0008] A curing and setting time determination integrated device for cementing material, the test sample forms two test end faces from the two end faces, the integrated device includes a box body, a clamping unit and a probe unit arranged in the box body respectively, a control unit for controlling the temperature and humidity in the box body, the clamping unit includes a clamping part formed with a positioning area matched with the test sample, and a turnover power element, wherein the test sample is clamped in the positioning area, and the turnover power element can drive the clamping part to turn up and down and drive the test sample to turn up from the two test end faces in turn; the probe unit includes an initial setting needle and a final setting needle arranged above the positioning area and capable of ascending and descending motion respectively.

[0009] According to one specific implementation and preferred aspect of the utility model, the clamping component includes a clamping seat, a plurality of clamping arms and a plurality of supporting arms arranged on the clamping seat respectively, wherein the plurality of clamping arms are distributed circumferentially around the sample, and the plurality of supporting arms are supported on the corresponding test end face respectively. Here, based on the plurality of clamping arms and the plurality of supporting arms, multi-direction clamping and supporting are formed, the overturning stability is high, and the supporting performance is good.

[0010] Preferably, the plurality of clamping arms are relatively fixed and form a limiting space matched with the sample. Here, the sample can be directly inserted into the limiting space formed by the plurality of clamping arms to form positioning, which is simple and convenient to operate.

[0011] Specifically, the plurality of clamping arms are divided into two clamping groups respectively close to the two test end faces, and each clamping group includes two clamping arms symmetrically arranged on opposite sides of the sample.

[0012] Preferably, the plurality of supporting arms are divided into two supporting groups corresponding to the two test end faces respectively, each supporting arm can be arranged in an extending and retracting manner along the horizontal direction, and when any test end face is upward, the corresponding supporting group is retracted to form an avoidance, and the other supporting group remains extended and forms a support. Here, during overturning, the supporting arms are extended to form a support, so that the condensed material in the sample is prevented from leaking out, and during testing, the test end face to be tested is completely exposed to increase the test area and improve the accuracy of the test result.

[0013] Specifically, each supporting group includes two supporting arms symmetrically arranged about the center line of the corresponding test end face.

[0014] According to another specific implementation and preferred aspect of the utility model, the initial setting needle is provided with a distance sensor for monitoring the lifting distance, and / or one side of the final setting needle is provided with an identification probe for judging the final setting state according to whether the test end face of the sample has a ring-shaped mark, and / or the probe unit further includes protective sleeves respectively sleeved on the initial setting needle and the final setting needle, and the initial setting needle and the final setting needle can be extended or retracted into the corresponding protective sleeves during lifting movement. Here, the deformation of the initial / final setting needle caused by collision during testing is effectively prevented, and the reliability of the test data is ensured.

[0015] According to another specific implementation and preferred aspect of the utility model, the clamping unit has a plurality of groups and is arranged in a horizontal direction in a side-by-side and spaced manner, and the probe unit can be arranged in a reciprocating motion along the arrangement direction of the plurality of clamping units. Here, curing and setting time measurement can be performed on multiple samples to improve efficiency.

[0016] According to another specific implementation and preferred aspect of the utility model, the control unit includes a control module arranged outside the box body, a heater and a humidifier arranged inside the box body, and a liquid inlet pipeline and a liquid outlet pipeline connected to the inside of the box body respectively.

[0017] In addition, the heater and humidifier are located at the bottom of the inner cavity of the chamber and directly below the positioning area; the control unit also includes a temperature and humidity meter located at the top of the inner cavity of the chamber.

[0018] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] Existing technologies require high temperature and humidity control for sample curing, necessitating multiple removals of the sample from the curing environment before setting time measurement (i.e., curing and testing are independent processes). Changes in the sample's environment during this process can affect the results. Furthermore, for some fast-setting sealing products with extremely short setting times, manual testing may result in the sample already fully set while being placed in the curing environment. Additionally, the need to change test needles during testing adds to the time constraints, leading to significant errors in the results. This application addresses these shortcomings by providing an integrated device for measuring the curing and setting time of cementitious materials. This integrated device places the sample inside the housing and clamps it within the positioning area formed by the clamping components, ensuring that one test end of the sample faces upwards. The system adjusts the temperature and humidity inside the chamber to create the optimal curing environment for the sample. Then, it drives the initial setting needle to move up and down, performing multiple tests on the corresponding test end face to determine the initial setting state. After the sample reaches the initial setting requirement, a flipping power component drives the clamping component to flip up and down, switching the test end face upwards. The final setting needle then moves up and down to perform a final setting state test on the corresponding test end face. Therefore, compared to existing technologies, this invention integrates the clamping unit, probe unit, and control unit into a single unit, achieving seamless connection between curing and setting time determination, effectively improving experimental efficiency and the accuracy of test results. Furthermore, based on the flipping design of the clamping component, it can automatically complete the conversion process from initial setting test to final setting test, greatly improving the continuity of the test and the accuracy of the test results.
