Description

TECHNICAL FIELD

[0001] The utility model relates to grouting material performance test instrument especially a device for measuring the flow performance of grouting material. BACKGROUND

[0002] Grouting material is regulated in terms of flow state, flowability and related indexes due to its construction form. Currently, the detection of grouting material flowability is based on the Technical Specification for Application of Reinforcing Steel Sleeve Grouting Connection JGJ 355-2015 and Sleeve Grouting Material for Reinforcing Steel Connection JG / T 408-2019. The detection method is as follows: after the grouting material is mixed and stirred according to the requirements, it is poured into a truncated cone circular mold and leveled with the top of the circular mold. The truncated cone circular mold is lifted. The maximum diameter and the average value of the diameter in the vertical direction of the grouting material flowing freely on the flat glass are the flowability of the grouting material.

[0003] There are many operations in the prior art flowability detection process that affect the accuracy of the data, such as visual leveling, using a ruler to measure the diameter, manually lifting the horizontal degree, height and speed of the truncated cone circular mold, which all have human errors, affecting the accuracy of the test results and being not conducive to ensuring the quality of the grouting material. SUMMARY

[0004] The utility model aims at the problems existing in the prior art and provides a device for measuring the flow performance of grouting material, which has high test accuracy, small human error and convenient operation.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a device for measuring the flow performance of grouting material, which comprises a timing module and a support frame. A charging container for containing grouting material is arranged on the support frame. The charging container can be rotated by 90°. A liquid level display window is arranged on the charging container. A liquid level scale is arranged at the liquid level display window. An opening is formed in the top of the charging container. A sealing cover is detachably arranged at the opening. An outlet pipe is arranged through the top of the sealing cover. An outlet valve is arranged on the outlet pipe.

[0006] In the above-mentioned scheme, the charging container is rotatably arranged on the support frame. The opening in the top of the charging container facilitates the injection and cleaning of the grouting material. The liquid level scale at the liquid level display window can be used to observe whether the volume of the grouting material in the charging container reaches the required amount. After the grouting material is injected, the sealing cover is covered, the charging container is rotated, the outlet pipe is leveled, and the timing module starts timing. The grouting material flows towards the outlet of the outlet pipe. When the grouting material flows out of the outlet, the timing is stopped. The flow performance of the grouting material is determined by the flow time.

[0007] Furthermore, the loading container is provided with rotating shafts on both sides, and the support frame is provided with a connecting cylinder for cooperating with the rotating shafts. An angle limiting structure is provided between the connecting cylinder and the rotating shaft.

[0008] The rotating shaft and connecting cylinder work together to achieve the rotational connection of the filling container, and the angle limiting structure allows the filling container to be rotated and positioned in both vertical and horizontal directions.

[0009] Furthermore, the angle limiting structure includes a movable baffle, a limiting block one, and a limiting block two disposed on the rotating shaft. The limiting block one is disposed on the connecting cylinder to cooperate with the limiting block two for limiting. The connecting cylinder is provided with a connecting seat, and the movable baffle is rotatably connected to the connecting seat.

[0010] The 90° rotation limit of the filling container is achieved by the cooperation of the limiting block one on the connecting cylinder and the limiting block two on the rotating shaft. The connecting cylinder is equipped with a connecting seat to rotate and connect the movable baffle. The filling container is positioned horizontally or vertically by rotating the movable baffle.

[0011] Furthermore, the discharge valve is a solenoid valve, which is electrically connected to the controller, and the timing module is integrated into the controller.

[0012] By using a solenoid valve and electrically connecting the solenoid valve, timing module, and controller, the solenoid valve and timing module can operate synchronously, ensuring the accuracy of the test.

[0013] Furthermore, a material level sensor is installed at the outlet of the discharge pipe, and the material level sensor is electrically connected to the controller.

[0014] A material level sensor is installed at the outlet of the discharge pipe to detect the flow position of the grout in real time. When the grout flows to the material level sensor, it sends a signal to the controller, which then controls the timing module to stop timing.

[0015] Furthermore, the bottom of the support frame is screwed with several leveling bases.

[0016] Rotate the leveling base to adjust the height of the support frame and achieve leveling.

[0017] Furthermore, the length of the discharge pipe is not less than 20cm.

[0018] The discharge pipe is made long enough to allow the grout to flow and improve the flowability test results.

[0019] Furthermore, a level detection component for adjusting the level is connected to the support frame.

[0020] A leveling detection component is used to check whether the support frame is placed on the ground level, ensuring consistent test results. A leveling base is used in conjunction with the component to adjust the initial levelness of the loading container.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The amount of grout injected into the filling container can be easily observed through the liquid level mark. After the required amount of grout is injected, the filling container is turned to a horizontal position. The grout in the filling container is made to flow to the outlet of the discharge pipe by opening the discharge valve. The timer module is used to record the flow time from opening the discharge valve to the grout flowing to the outlet of the discharge pipe to determine whether the fluidity performance of the grout meets the standard. The operation is convenient and the test is accurate.

[0023] (2) By setting liquid level marks and angle limiting structures, the amount of grouting material is guaranteed and the angle of the loading container is kept horizontal each time it discharges, thereby reducing human error.

[0024] (3) Set the controller to connect to the discharge valve, timing module and material level sensor to ensure accurate timing. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0030] like Figs. 1-3 As shown, an apparatus for measuring the flow properties of grout includes a timing module 201 and a support frame 11. The support frame 11 is provided with a loading container 1 for holding grout. The loading container 1 can rotate 90°. The loading container 1 is provided with a liquid level display window 12 and a liquid level mark 13. The top of the loading container 1 has an opening 6. A sealing cover 3 is detachably provided at the opening 6. A discharge pipe 4 is provided through the top of the sealing cover 3. A discharge valve 7 is provided on the discharge pipe 4.

[0031] In the above scheme, the loading container 1 is rotatably mounted on the support frame 11. The opening 6 at the top of the loading container 1 facilitates the injection and cleaning of the grout. The liquid level mark 13 at the liquid level display window 12 can be used to observe whether the volume of the grout in the loading container 1 has reached the required amount. After the grout is injected, the sealing cover 3 is closed, the loading container 1 is rotated so that the discharge pipe 4 is horizontal, and the timing is started by the timing module 201. The grout flows towards the outlet of the discharge pipe 4 until it flows out of the outlet of the discharge pipe 4, at which point the timing stops. The flow time is used to judge the flow performance of the grout.

[0032] The filling container 1 is cylindrical, and a liquid level display window 12 is provided on the filling container 1. The liquid level mark 13 can be one or more marks, which can clearly show the liquid level height of the slurry in the filling container 1. A rubber sealing ring is provided between the filling container 1 and the sealing cap 3 to prevent the slurry from overflowing during the test and causing abnormal data. The sealing cap 3 and the discharge pipe 4 can be an integral structure or a threaded connection.

[0033] The bottom of the filling container 1 is closed, and a removable sealing cover 3 is installed on the top. A hollow stainless steel discharge pipe 4 is set off the sealing cover 3 off-center. The controller 2 can be connected to the filling container 1, the support frame 11, or a separate connection. The controller 2 consists of a timing module 201, a data processing module 202, and an output display module 203. The data processing module 202 is connected to the timing module 201 to determine the flow performance of the grout based on the flow time of the grout. The data output display module 203 is connected to the data processing module 202 to display the flow performance determination result.

[0034] In some embodiments, the timing module 201 can be turned on and off manually or controlled by the controller 2.

[0035] Furthermore, the loading container 1 is provided with rotating shafts 8 on both sides, and the support frame 11 is provided with a connecting cylinder 9 for cooperating with the rotating shafts 8. An angle limiting structure 10 is provided between the connecting cylinder 9 and the rotating shafts 8.

[0036] The rotating shaft 8 and the connecting cylinder 9 work together to achieve the rotational connection of the filling container 1. The angle limiting structure 10 is used to enable the filling container 1 to rotate and be positioned in both vertical and horizontal directions.

[0037] The angle limiting structure 10 may include a block or column structure set on the rotating shaft 8 and the connecting cylinder 9, so that the loading container 1 can be placed in two stable forms, horizontal and vertical.

[0038] Furthermore, the angle limiting structure 10 includes a movable baffle 101, a limiting block one 102, and a limiting block two 103 disposed on the rotating shaft 8. The limiting block one 102 is disposed on the connecting cylinder 9 to cooperate with the limiting block two 103 for limiting. A connecting seat 104 is disposed on the connecting cylinder 9, and the movable baffle 101 is rotatably connected to the connecting seat 104.

[0039] By cooperating with the limiting block 102 on the connecting cylinder 9 and the limiting block 103 on the rotating shaft 8, the 90° rotation limit of the loading container 1 is achieved. The connecting seat 104 on the connecting cylinder 9 is provided to rotatably connect the movable baffle 101. The loading container 1 is positioned horizontally or vertically by rotating the movable baffle 101.

[0040] The connecting seat 104 is a plate structure, and a locking block can be set on the connecting seat 104 to limit the rotation angle of the movable baffle 101.

[0041] Furthermore, the discharge valve 7 is a solenoid valve, which is electrically connected to the controller 2, and the timing module 201 is integrated into the controller 2.

[0042] By using a solenoid valve and electrically connecting the solenoid valve, timing module 201, and controller 2, the solenoid valve and timing module 201 can be synchronized to ensure the accuracy of the test.

[0043] Furthermore, a material level sensor 15 is provided at the outlet of the discharge pipe 4, and the material level sensor 15 is electrically connected to the controller 2.

[0044] A material level sensor 15 is installed at the outlet of the discharge pipe 4 to detect the flow position of the grout in real time. When the grout flows to the material level sensor 15, it transmits a signal to the controller 2, and the controller 2 controls the timing module 201 to stop timing.

[0045] In this embodiment, the discharge pipe 4 is a transparent plastic structure, and the material level sensor 15 is a shielded photoelectric sensor. The material level sensor 15 is detachably installed on the outside of the discharge pipe 4 by means of a pipe clamp 16 or a bolt.

[0046] Furthermore, the bottom of the support frame 11 is screwed with several leveling bases 14.

[0047] Rotate the leveling base 14 to adjust the height of the support frame 11 and achieve leveling.

[0048] The support frame 11 includes steel frames on both sides of the loading container 1, and a leveling base 14 is provided at the bottom of the steel frame. The leveling base 14 includes screws to be screwed to the bottom of the support frame 11.

[0049] Furthermore, the length of the discharge pipe 4 is not less than 20cm.

[0050] The discharge pipe 4 is designed to be long enough to allow the grout to flow and improve the flowability test results.

[0051] Furthermore, a level detection component 5 for adjusting the level is connected to the support frame 11.

[0052] The horizontal detection component 5 is used to check whether the support frame 11 is placed on the ground horizontally, ensuring consistent test results. The leveling base 14 is used in conjunction with the horizontal adjustment to adjust the initial levelness of the loading container 1.

[0053] The horizontal detection component 5 can be selected as a cross-shaped bubble level.

[0054] In actual use, the flowability-flow time correspondence of the grout with qualified flowability obtained according to existing standards is pre-input into the data processing module 202 for relevant judgment and output. A flow test is first conducted using this device, with the liquid level set. Flow time information (usually in the form of average value and range; the flow time information is the time from the start of grout flow to the point where grout flows out of the stainless steel pipe) is collected to establish the flowability-flow time correspondence. This serves as the basis for the data processing module 202 to judge the subsequent measured flowability of the grout. This method facilitates operation and improves efficiency by determining the flowability of the grout.

[0055] In actual use, the cylindrical loading container 1 is leveled using the horizontal detection component 5 and the leveling base 14. The upper sealing cover 3 of the loading container 1 is opened, and the mixed grout is poured into the loading container 1. The liquid level is observed through the liquid level display window 12. When the liquid level reaches the liquid level line, the pouring is stopped, and the upper sealing cover 3 of the cylindrical loading container 1 is closed. During testing, the loading container 1 is adjusted from vertical to horizontal. When the discharge valve 7 is opened, the timing module 201 in the controller 2 is triggered and starts timing. When the material level sensor 15 detects that grout is flowing to the designated position, the timing module 201 stops timing. The data processing module 202 judges the flow performance of the grout based on the duration information provided by the timing module 201 and the pre-entered judgment threshold. Then, the judgment result is output and displayed through the judgment output display module 203.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
