Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction measurement, especially relate to a consistency measuring device. BACKGROUND

[0002] Cement is an indispensable basic material in building engineering, and its quality is closely related to the safety and durability of building structure. In building construction, it is usually necessary to detect cement, and standard consistency and setting time are two important indicators for measuring whether the cement meets the product standard. As a detection instrument for cement and concrete industry, the cement consistency instrument compares the settlement height of the standard test rod and the standard test needle in the sample during the measurement process with the product standard, so as to determine whether the cement meets the standard.

[0003] However, most cement consistency instruments rely on manual operation in reading, recording and calculating, which may lead to measurement errors. To improve measurement accuracy, related technologies have proposed a digital direct-reading cement standard consistency and setting time tester. The instrument includes a slide rod, a digital display and a standard test rod. The standard test rod and the slide rod are detachably connected. The slide rod is equipped with a sensor and can slide in the vertical direction. The digital display can display the displacement of the slide rod in real time, and the consistency data of the cement can be calculated according to the displacement data of the slide rod. The data acquisition process does not require manual intervention, reducing measurement errors.

[0004] The above-mentioned cement consistency instrument also has a release structure, which is provided with a baffle and a dial. The realization of the displacement of the slide rod requires manual dialing of the dial to drive the baffle to rotate until the baffle no longer presses the surface of the slide rod. The displacement process requires manual intervention, and the degree of automation is low. Moreover, the digital display in the above-mentioned cement consistency instrument acquires displacement data in real time by setting a contact magnetic sensor on the rod of the slide rod. After multiple measurements, the magnetic change of the slide rod itself may affect the reading, thereby affecting the measurement accuracy. UTILITY MODEL CONTENTS

The above process does not need manual calculation, and the measurement accuracy is improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar components or components having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0027] In the description of the present application, unless explicitly defined and limited otherwise, the terms "connected", "connection" and "fixed" should be understood broadly, for example, can be fixedly connected, can be detachably connected, can be mechanically connected, can be electrically connected, can be directly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] In the description of the present application, unless explicitly defined and limited otherwise, the first feature "on" or "below" the second feature can include that the first feature and the second feature are in direct contact, or can include that the first feature and the second feature are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0029] The technical scheme of the present application is further illustrated below by combining the drawings and through specific embodiments.

[0030] As Figures 1-2As shown, the utility model provides a consistency measuring device, including test platform 1, measurement component 3 and clamping structure 4, wherein test platform 1 includes fixedly connected support base 11 and support column 12, and support base 11 is used for placing the sample 2 to be measured. Measurement component 3 includes measurement auxiliary rod 31, consistency measuring piece 32 and displacement sensor 33, measurement auxiliary rod 31 and consistency measuring piece 32 are connected, and consistency measuring piece 32 is arranged below measurement auxiliary rod 31, and measurement auxiliary rod 31 is movably arranged on support column 12, and measurement auxiliary rod 31 can be movably arranged on support column 12, or be slidably arranged on support column 12, or be rollingly arranged on support column 12 by setting toothed structure on the outer surface, which is not limited here. Measurement auxiliary rod 31 can drive consistency measuring piece 32 to move into the sample 2 to be measured, and displacement sensor 33 is arranged on support column 12 and above measurement auxiliary rod 31, and displacement sensor 33 can be arranged on the top surface of support column 12. Displacement sensor 33 is used for measuring the displacement data of measurement auxiliary rod 31. During the displacement measurement of measurement auxiliary rod 31, displacement sensor 33 is always not in contact with measurement auxiliary rod 31, that is, the displacement measurement process avoids data errors caused by various factors when the two are in contact, and the measurement accuracy is improved.

[0031] Displacement sensor 33 can be a laser displacement sensor 33, which can emit laser. When the laser reaches the top surface of measurement auxiliary rod 31, it can be reflected back and received by the receiving element inside the laser displacement sensor 33, and then the optical signal is converted into an electrical signal. The signal processing circuit inside the sensor processes the electrical signal and obtains the displacement data of measurement auxiliary rod 31 by combining the algorithm. To improve the reflection effect of measurement auxiliary rod 31, a metal material can be used to make measurement auxiliary rod 31. Displacement sensor 33 can also be other types of non-contact displacement sensors 33. Using non-contact displacement sensors 33 can avoid errors caused by friction between the pointer and the scale on the measurement dial or naked eye reading in traditional consistency measuring devices. The consistency measuring device proposed by the utility model can improve the accuracy and reliability of the measurement results.

[0032] As shown in Figure 1 and Figure 2 , clamping structure 4 includes first clamping block 41, second clamping block 42 and driving part 43, first clamping block 41 and second clamping block 42 are arranged on support column 12, and driving part 43 can adjust the distance between first clamping block 41 and second clamping block 42 to clamp or loosen measurement auxiliary rod 31. Compared with the process that needs human intervention in the prior art, driving part 43 can automatically adjust the distance between first clamping block 41 and second clamping block 42, and the automation degree of the consistency measuring device proposed by the utility model is improved.

[0033] To realize the spacing adjustment effect of the driving member 43 on the first clamping block 41 and the second clamping block 42, at least one of the first clamping block 41 and the second clamping block 42 can be slidingly arranged on the support column 12, and the driving member 43 can drive the first clamping block 41 and the second clamping block 42 to slide relative to each other, so as to adjust the spacing of the first clamping block 41 and the second clamping block 42, and make the first clamping block 41 and the second clamping block 42 clamp or release the measurement auxiliary rod 31. The driving member 43 can be a pneumatic cylinder, which can be arranged on one of the first clamping block 41 and the second clamping block 42, and the linear reciprocating motion of the pneumatic cylinder can realize the relative sliding of the first clamping block 41 and the second clamping block 42, so as to adjust the spacing between the first clamping block 41 and the second clamping block 42, and make the first clamping block 41 and the second clamping block 42 clamp or release the measurement auxiliary rod 31. In other embodiments, a pneumatic cylinder can also be connected to the first clamping block 41 and the second clamping block 42. To enhance the clamping effect of the first clamping block 41 and the second clamping block 42 on the measurement auxiliary rod 31, a non-slip pad or a non-slip coating can be arranged on the side of the first clamping block 41 and the second clamping block 42 close to the measurement auxiliary rod 31.

[0034] To realize the relative sliding of the first clamping block 41 and the second clamping block 42 on the support column 12, a sliding rail can be arranged on the support column 12, which can be used for sliding of the first clamping block 41 and / or the second clamping block 42, so as to improve the adverse phenomena generated during the sliding process of the first clamping block 41 and the second clamping block 42, such as sliding jamming or poor sliding stability. A guide member 44 can also be arranged on the support column 12, and the guide member 44 can be arranged in the perforations of the first clamping block 41 and the second clamping block 42. The first clamping block 41 and the second clamping block 42 are slidingly connected to the guide member 44, and the guide member 44 can provide a guiding action for the first clamping block 41 and the second clamping block 42. Under the driving action of the driving member 43, the first clamping block 41 and the second clamping block 42 can slide relative to each other along the guide member 44. The arrangement of the guide member 44 can also reduce the processing requirements of the support column 12, thereby reducing the processing cost of the support column 12.

[0035] Specifically, the clamping structure 4 can further comprise an adjusting member 45, the first clamping block 41 and the second clamping block 42 are both in threaded connection with the adjusting member 45, threads are processed on the connecting surfaces of the adjusting member 45 and the first clamping block 41 and the second clamping block 42, the adjusting member 45 is connected with the driving member 43, the driving member 43 can drive the adjusting member 45 to rotate, and the adjusting member 45 and the guide member 44 have a cooperative action, and the action mechanism of the two is similar to the working principle of a nut-screw pair, that is, when the driving member 43 drives the adjusting member 45 to rotate, the first clamping block 41 and the second clamping block 42 can slide relative to each other along the guide member 44. In order to ensure the realization of the relative sliding process of the first clamping block 41 and the second clamping block 42 along the guide member 44, the threads near the first clamping block 41 and the second clamping block 42 of the adjusting member 45 can be processed in opposite directions, so that the first clamping block 41 and the second clamping block 42 can move in opposite directions, or the threads near the first clamping block 41 and the second clamping block 42 of the adjusting member 45 can be processed in the same direction but with different pitches, so that the movement speeds of the first clamping block 41 and the second clamping block 42 are different. After the adjusting member 45 is arranged, the driving member 43 only needs to be arranged on one of the first clamping block 41 or the second clamping block 42, and then the driving member 43 is connected with the adjusting member 45 and used to drive the adjusting member 45 to rotate, thereby reducing the driving cost of the consistency measuring device.

[0036] The driving member 43 can be an electric motor, the electric motor is connected with the adjusting member 45, and by adjusting the rotating direction of the electric motor, the adjusting member 45 can be rotated clockwise or counterclockwise, so that the first clamping block 41 and the second clamping block 42 can relatively approach or move away along the guide member 44, and finally the first clamping block 41 and the second clamping block 42 can clamp or release the measuring auxiliary rod 31. It should be noted that, in addition to the air cylinder and the electric motor, any component that can drive the first clamping block 41 and the second clamping block 42 to slide relative to each other can be used as the driving member 43 of the utility model, and here is not limited too much.

[0037] In order to prolong the service life of the guide member 44 and the adjusting member 45, a mounting seat 122 can be arranged on the upper part of the mounting table 121, part of the structure of the first clamping block 41 and the second clamping block 42 is placed in the mounting seat 122, and the guide member 44 and the adjusting member 45 are arranged in the mounting seat 122, thereby reducing the influence of dust or humid air in the surrounding environment on the clamping structure 4.

[0038] When the first clamping block 41 and the second clamping block 42 clamp the measurement auxiliary rod 31, displacement of the measurement auxiliary rod 31 can be limited. When the first clamping block 41 and the second clamping block 42 release the measurement auxiliary rod 31, the measurement auxiliary rod 31 can be displaced under the action of gravity and drive the consistency measuring member 32 connected thereto to move into the sample 2 to be measured. When testing the consistency, the measurement auxiliary rod 31 can be first moved to contact the bottom of the consistency measuring member 32 connected thereto and the sample 2 to be measured, and then the first clamping block 41 and the second clamping block 42 are clamped on the measurement auxiliary rod 31 by the driving member 43, and the initial data of the measurement auxiliary rod 31 at this time is measured by the displacement sensor 33. After clamping for 1-2 seconds, the first clamping block 41 and the second clamping block 42 are released on the measurement auxiliary rod 31 by the driving member 43, so that the measurement auxiliary rod 31 drives the consistency measuring member 32 to move into the sample 2 to be measured, and the measurement data of the displacement sensor 33 is obtained after the consistency measuring member 32 cannot continue to sink into the sample 2 to be measured or the measurement auxiliary rod 31 is released for thirty seconds. The initial data and the measurement data at this time are subtracted to obtain the distance between the bottom of the consistency measuring member 32 and the bottom of the sample 2 to be measured, which is the consistency of the sample 2 to be measured. Comparing the distance with the standard consistency specification of the sample 2 to be measured can determine whether the state of the sample 2 to be measured meets the standard consistency requirement. If the consistency requirement is met, the sample 2 to be measured can be further measured, for example, whether the sample 2 to be measured reaches the initial setting state or the final setting state.

[0039] Specifically, as shown in Figure 1 the order of the consistency measuring member 32 from left to right, the consistency measuring member 32 can be a standard consistency test rod, an initial setting test needle, or a final setting test needle. The standard consistency test rod is in a columnar shape and is made of a corrosion-resistant metal with an effective length of 50mm±1mm and a diameter of 10mm±0.05mm. The initial setting test needle is made of steel and has an effective length of 50mm±1mm. The final setting test needle has an effective length of 30mm±1mm. To facilitate the use of the consistency measuring device to measure whether the sample 2 to be measured meets the standard consistency state, the initial setting state, and the final setting state, the consistency measuring member 32 and the measurement auxiliary rod 31 can be detachably connected. The measurement auxiliary rod 31 and the consistency measuring member 32 are easily detached, and the detachment process is simple and easy to implement. For example, threads can be processed at the connection between the measurement auxiliary rod 31 and the consistency measuring member 32 to screw them together. Alternatively, magnets with opposite magnetic properties can be arranged at the connection between the measurement auxiliary rod 31 and the consistency measuring member 32 to magnetically connect them. Thus, after it is measured that the sample 2 to be measured meets the standard consistency requirement, an operator can timely replace the standard consistency test rod with the initial setting test needle or the final setting test needle, and the distance between the initial setting test needle or the final setting test needle and the bottom of the sample 2 to be measured can be used to determine whether the sample 2 to be measured reaches the initial setting state or the final setting state.

[0040] For example, when the distance between the consistency measuring member 32 and the bottom of the cement sample is 6.0 mm ± 1.0 mm, it is determined that the cement sample reaches the standard consistency. When the distance between the consistency measuring member 32 and the bottom of the cement sample is 4.0 mm ± 1.0 mm, it is determined that the cement sample reaches the initial setting state. When the distance between the consistency measuring member 32 and the bottom of the cement sample is 0.5 mm, it is determined that the cement sample reaches the final setting state. To avoid damaging the surface of the cement sample by the final setting test needle, a ring-shaped accessory can be arranged on the side of the final setting test needle that contacts the cement sample. When the ring-shaped accessory cannot leave marks on the cement sample, it is determined that the cement sample reaches the final setting state.

[0041] To facilitate the accommodation of the sample 2 to be measured and to maintain the cleanliness of the test platform 1 during the measurement of the sample 2 to be measured, a test mold can be processed and the sample 2 to be measured can be placed in the test mold. The test mold is made of corrosion-resistant metal with sufficient hardness. The test mold is a truncated cone with a depth of 40 mm ± 0.2 mm, a top inner diameter of 65 mm ± 0.5 mm, and a bottom inner diameter of 75 mm ± 0.5 mm. Each test mold should be equipped with a flat glass bottom plate or a metal bottom plate with a side length or diameter of about 100 mm and a thickness of 4 mm-5 mm. The flat glass bottom plate or the metal bottom plate should be placed on the center of the upper surface of the support base 11 during measurement.

[0042] The displacement direction of the measurement auxiliary rod 31 is preferably downward along the vertical direction to drive the consistency measuring member 32 to fall into the sample 2 to be measured, thereby avoiding measurement errors caused by uneven distribution of the sample 2 to be measured in the test mold. To ensure the vertical displacement of the measurement auxiliary rod 31, an installation table 121 can be arranged on the support column 12, and a through hole is formed in the installation table 121 along the vertical direction. The measurement auxiliary rod 31 is movably arranged in the through hole along the vertical direction before measurement. The measurement auxiliary rod 31 can be processed in a cylindrical shape, which is simple in shape and easy to assemble, facilitating production and processing. In addition, to improve the movement of the measurement auxiliary rod 31 on the support column 12, the outer circumferential side of the measurement auxiliary rod 31 can be processed as a smooth surface.

[0043] In order to ensure the reliability of the measurement result, the whole of the sample 2 to be measured needs to be kept in a horizontal state. At least two adjusting nuts 113, a first horizontal measuring instrument 111 and a second horizontal measuring instrument 112 arranged at an included angle can be arranged on the support base 11. The first horizontal measuring instrument 111 and the second horizontal measuring instrument 112 can be arranged vertically and are respectively used for measuring the horizontal degree of the first horizontal direction and the second horizontal direction perpendicular to each other, so as to test whether the upper surface of the support base 11 is parallel to the horizontal plane. The first horizontal measuring instrument 111 comprises a support, a bubble and a horizontal tube. The support is mounted on the support base 11. The horizontal tube is arranged on the support. The bubble is movably arranged in the horizontal tube. When the upper surface of the support base 11 is parallel to the horizontal plane, the bubble is in the central position of the horizontal tube. The working principle and structural components of the second horizontal measuring instrument 112 are the same as those of the first horizontal measuring instrument 111. If the bubbles in the first horizontal measuring instrument 111 and the second horizontal measuring instrument 112 are not in the central position, the adjusting nuts 113 need to be adjusted. The adjusting nuts 113 can adjust the inclination degree of the upper surface of the support base 11 compared with the horizontal plane. When the first horizontal measuring instrument 111 and the second horizontal measuring instrument 112 display that the upper surface of the support base 11 is parallel to the horizontal plane, the test mold containing the sample 2 to be measured can be placed on the support base 11, and subsequent measurement can be performed.

[0044] The consistency measuring device can further comprise a control system 5 to improve the intelligent degree of the consistency measuring device and the convenience of the operation process. Specifically, the control system 5 is electrically connected with the driving member 43 through wires for controlling the driving member 43 to make the first clamping block 41 and the second clamping block 42 clamp or release the measuring auxiliary rod 31. The control system 5 and the displacement sensor 33 are electrically connected through wires to obtain and record the displacement data of the measuring auxiliary rod 31, avoiding manual reading or measurement, and improving the accuracy of the measurement result.

[0045] For the convenience of the operator, the control system 5 can be provided with an instruction button with different functions. The operator can press the relevant button to control the relevant structure to complete the specified function. For example, the control system 5 can be provided with an on-off key, a "loosen" button, a "clamp" button, a "standard consistency" button, a "initial setting" button, a "final setting" button, an "initial reading" button, a "final reading" button, a "determine" button, a "cancel" button and an "end" button on the display screen. The on-off key is used to turn on or off the display screen in the control system 5, which is convenient for directly displaying the measurement data of the displacement sensor 33 through the display screen. The "loosen" and "clamp" buttons are used to control the driving member 43 to adjust the distance between the first clamping block 41 and the second clamping block 42, so that the first clamping block 41 and the second clamping block 42 loosen or clamp the measurement auxiliary rod 31. The "standard consistency", "initial setting" and "final setting" buttons correspond to the marking of the state of the sample 2 to be measured by the operator. The "initial reading" and "final reading" buttons correspond to the measurement data of the displacement sensor 33 when the bottom of the consistency measuring member 32 and the sample 2 to be measured are in contact, and the measurement data of the displacement sensor 33 when the consistency measuring member 32 cannot continue to sink into the sample 2 to be measured or the measurement auxiliary rod 31 is released for thirty seconds. The difference between the two can be used as the basis for determining whether the sample 2 to be measured reaches the standard consistency, the initial setting state and the final setting state. The "cancel" button can cancel the misoperation of the operator in the last step. It should be noted that only after the sample 2 to be measured reaches the standard consistency, the sample 2 to be measured needs to be measured to determine whether the sample 2 to be measured reaches the initial setting state and the final setting state.

[0046] Taking the cement sample as an example, before the consistency measurement, the various components of the consistency measurement device need to be tested and inspected, for example, whether the measurement auxiliary rod 31 can smoothly drive the consistency measurement piece 32 to move, whether the bubbles in the first horizontal measuring instrument 111 and the second horizontal measuring instrument 112 remain centered, etc. After confirming that the upper surface of the support base 11 is parallel to the horizontal plane, the start key and the "standard consistency" button can be clicked to perform the measurement of the standard consistency process. First, the glass bottom plate can be placed at the center position of the upper surface of the support base 11, and then the measurement auxiliary rod 31 is moved downward until the bottom of the consistency measurement piece 32 connected thereto is in contact with the glass bottom plate. The "initial reading" button is clicked to record the measurement data of the measurement auxiliary rod 31 measured by the displacement sensor 33 at this time. Then the measurement auxiliary rod 31 is moved upward until the bottom of the consistency measurement piece 32 connected thereto allows the test mold for accommodating the cement sample to be placed on the glass bottom plate. The cement and water are mixed according to a certain proportion to make the cement sample, and the water consumption at this time is recorded. After the cement sample is stirred uniformly and placed in the test mold and smoothed, the test mold containing the cement sample is placed on the glass bottom plate. The measurement auxiliary rod 31 is moved to the bottom of the consistency measurement piece 32 connected thereto and the surface of the cement sample in the test mold is in contact, and then the "clamping" button is clicked to clamp the measurement auxiliary rod 31 by the first clamping block 41 and the second clamping block 42. After clamping for 1 to 2 seconds, the "release" button is clicked to allow the measurement auxiliary rod 31 to drive the consistency measurement piece 32 to fall freely into the cement sample under the action of gravity. When the consistency measurement piece 32 cannot continue to sink into the cement sample or the measurement auxiliary rod 31 is released for thirty seconds, the "final reading" button is clicked to record the data of the measurement auxiliary rod 31 measured by the displacement sensor 33 at this time. The difference between the two is the distance between the consistency measurement piece 32 and the bottom of the cement sample, which is the consistency of the cement sample. Comparing the distance with the standard consistency specification of the cement sample can determine whether the state of the cement sample meets the requirements of the standard consistency.

[0047] If the consistency requirement is met, the previous water consumption data can be recorded, and the measurement of the cement sample is continued, for example, further measurement of whether the cement sample reaches the initial setting state or the final setting state. If the consistency requirement is not met, the water amount for configuring the cement sample needs to be adjusted again until the cement sample meets the standard consistency requirement, and the water consumption data is recorded. For the convenience of statistics, "+" and "-" buttons can be added on the display screen of the control system 5 for recording the water consumption data. After the input is completed, the "confirm" and "end" buttons are clicked to complete the saving of the standard consistency related data. The related tests of the initial setting and the final setting states and the like are similar to the above and will not be described in detail.
