Description

Technical Field

[0001] The utility model belongs to the technical field of tensile testing devices, and in particular relates to a tensile testing device for viscosity of a mining glue solid powder. Background Art

[0002] Mining cement powder is a commonly used material, widely used in mining engineering, tunnel engineering, underground engineering and other fields. In order to ensure the stability and reliability of mining cement powder in practical applications, it is necessary to test its viscosity and tensile properties. Through viscosity testing, the viscosity of the cement powder can be determined, and its flow characteristics under different temperature, pressure and shear conditions can be understood. This is of great significance for engineering construction and material selection. It can ensure that the cement powder has appropriate pumpability, fluidity and adhesion during the construction process. Through tensile testing, the tensile strength, breaking strength and elongation of the cement powder can be determined to evaluate its durability and reliability under stress. This is of great significance for selecting suitable cement powder materials, designing engineering structures and optimizing the construction process.

[0003] The existing tensile test of cement powder viscosity cannot ensure the uniformity of cement powder mixing and the same shape and size when stretched, so a tensile test device for cement powder viscosity for mining is designed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a device for tensile testing the viscosity of cement powder for mining, which solves the problems of uniform mixing of cement powder and uniform shape and size during stretching.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mining glue powder viscosity tensile testing device, comprising a base plate, two tracks are fixedly installed on the top of the base plate, push-pull blocks are slidably connected to the top of the two tracks, grab clamps are fixedly installed on the opposite sides of the two push-pull blocks, displacement sensors are fixedly installed on one side of the two push-pull blocks, an operator is fixedly installed on the top of the base plate, an agitator is fixedly installed on the top of the base plate, a motor is fixedly installed on the top of the agitator, a stirring rod is fixedly installed on the output end of the motor, a hook is fixedly installed on one side of the agitator, a table board is fixedly installed on the top of the base plate, and a mold and a scraper are placed on the top of the table board.

[0006] Preferably, a driving motor is fixedly mounted on one side of the two push-pull blocks.

[0007] The above technical solution has the advantage that the staff can operate the buttons on the operator to enable the driving motor to drive the push-pull block to move on the track, thereby performing a tensile test on the glue powder.

[0008] Preferably, force sensors are fixedly mounted on the tops of the two gripping clamps.

[0009] The above technical solution has the advantage that the two solidified and demolded adhesive powders are clamped by two clamps, and then the buttons are operated to drive the push-pull blocks to move, thereby stretching the adhesive powders. The force sensor on the clamps can accurately measure and record the changes in the stretching force.

[0010] Preferably, a stretch line is connected between the two displacement sensors.

[0011] The above technical solution has the advantage that the displacement sensor can accurately measure the displacement change of the sample in the stretching device through the stretching line. By recording the displacement data of the sample, the deformation degree of the sample under the tensile force can be understood, thereby evaluating its tensile performance.

[0012] Preferably, a button is fixedly mounted on the top of the operator, and a display screen is fixedly mounted on the front of the operator.

[0013] The advantage of the above technical solution is that the staff can operate the drive motor through the buttons on the operator, and then the data recorded by the force sensor and the displacement sensor will be displayed on the display screen.

[0014] Preferably, a fan blade is fixedly mounted on the bottom of the stirring rod.

[0015] The above technical solution has the advantage that the staff puts the configured glue powder into the agitator, and then starts the motor, the motor drives the agitator rod to rotate, and the agitator rod drives the fan blades to rotate, thereby stirring the glue powder.

[0016] Preferably, a spoon is placed on the hook.

[0017] The above technical solution has the advantage that the spoon can be removed from the hook, and the staff can use the spoon to scoop the glue powder stirred in the stirrer into the mold, and then use a scraper to scrape the glue powder flat.

[0018] Preferably, brackets are fixedly mounted on the four bottom corners of the table top.

[0019] The advantage of the above technical solution is that the four brackets can fix the table top, making it more stable and not easily tilted during use, thereby increasing the accuracy of the test.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The stirrer can fully mix the cement powder and solvent to ensure that the solid particles are evenly dispersed in the liquid to avoid agglomeration or uneven mixing, which is very important for the subsequent experimental operation and the accuracy of the results. The stirrer can continuously stir the glue during the tensile test to prevent the solid particles from settling or stratifying. This can ensure the uniformity and consistency of the cement powder during the experiment and ensure the reliability and comparability of the experimental data.

[0022] 2. Through the setting of the mold, the mold can ensure that the sample maintains a consistent shape and size during the curing process. The mold can pour the glue powder slurry into it according to the specified size and shape requirements, and form a sample with a standard size and shape through the curing process. These samples are used for subsequent tensile tests to evaluate the performance and quality of the glue powder. BRIEF DESCRIPTION OF THE DRAWINGS
