Description

Technical Field

[0001] This utility model relates to the field of support technology for flow cones, specifically to a support device for detecting the flowability of grouting material. Background Technology

[0002] In construction engineering, the flowability of fluid materials such as grouting materials is a key indicator for evaluating their construction performance. Flowability testing typically employs the flow cone method, which measures the time it takes for the material to flow out of the cone to determine its fluidity. Currently, the testing standards for the flowability of different fluid materials include Q / CR 409-2017 "Technical Conditions for Grouting of Pipes in Post-Tensioned Prestressed Concrete Beams for Railways", NB / T 20125-2012 "Technical Specification for Grouting Construction of Foundations of Important Safety Equipment in Pressurized Water Reactor Nuclear Power Plants", JC / T 1083-2008 "Test Method for Compatibility of Cement and Water-Reducing Agents", BS EN 445-2007 Grout for Prestressing Tendons - Test Methods, and ASTM D6910 / D6910M-19 Standard Test Method for Marsh Funnel Viscosity of Construction Slurries, etc.

[0003] Different industry standards have different requirements for the size and testing methods of flow cones, which means that special supports are required for testing, increasing equipment costs and operational complexity; existing supports have the following drawbacks; (1) Poor adaptability; one type of support usually corresponds to only one standard flow cone. (2) The flow rate time relies heavily on manual timing, which is subject to human error and lacks accuracy and precision.

[0004] Therefore, there is an urgent need to design a flow cone support that is highly versatile, adjustable, and automated. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a support device for detecting the flowability of grouting material. This solves the problems in the prior art where the support does not have an adjustment function, cannot be applied to different types of flow cones, and the grout flows out of the flow cone under its own weight, resulting in low accuracy of manually recording the flow time.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a support device for testing the fluidity of grouting material, comprising: seat body; A support member, which is mounted on a base and has through holes; An adjusting member, connected to a support member, having a first state fixed to the support member and a second state sliding relative to the support member, the adjusting member having a limiting hole corresponding to a through hole below it; and, The measuring component includes an infrared sensor, a microprocessor, and a timer. The infrared sensor is mounted on a support and located on one side of the perforation. The microprocessor is electrically connected to the infrared sensor and the timer.

[0007] In some embodiments, the support includes at least two support tubes and a base plate. The lower ends of the two support tubes are fixedly connected to the base body. The base plate is connected to the two support tubes. The base plate has the through hole. The infrared sensor is mounted on the base plate. The side wall at the upper end of the support tube has a positioning hole. The adjusting component includes at least two adjusting rods, a top plate, and two locking bolts. The lower ends of the two adjusting rods are slidably inserted into the two supporting tubes, and the upper ends of the two adjusting rods are fixedly connected to the top plate. The top plate has the limiting hole, and the adjusting rods have multiple threaded holes spaced apart. The locking bolts pass through the positioning holes and can be screwed into each of the threaded holes respectively.

[0008] In some embodiments, a receiving space for placing a mixing pot is formed between the base and the bottom plate, and an installation space for placing a flow cone is formed between the bottom plate and the top plate.

[0009] In some embodiments, the inner diameter of the limiting hole is 3-6 times the inner diameter of the through hole.

[0010] In some embodiments, the length of the adjusting rod is greater than the length of the support tube.

[0011] In some embodiments, the distance between the centers of two adjacent threaded holes is 10 mm.

[0012] In some embodiments, the base, bottom plate, and top plate are all disc-shaped, and the through holes and limiting holes are all circular holes.

[0013] In some embodiments, a plurality of leveling components are further included, all of which are mounted on the base and are used to adjust the level of the base.

[0014] In some embodiments, the leveling component is an adjusting bolt, and the base is provided with a plurality of threaded adjusting holes, wherein the adjusting bolt is threadedly rotatably connected to the threaded adjusting holes.

[0015] In some embodiments, a spirit level is also included, which is mounted on the base.

[0016] Compared with the prior art, the present invention provides a support device for detecting the flowability of grout. A support member is mounted on a base, and the support member has a through hole. An adjusting member is connected to the support member and has a first state where it is fixed to the support member and a second state where it slides relative to the support member. The adjusting member has a limiting hole that corresponds to the through hole below. An infrared sensor is mounted on the support member and located on one side of the through hole. A microprocessor is electrically connected to the infrared sensor and a timer. In the second state, the distance between the through hole and the limiting hole can be adjusted by sliding the adjusting member relative to the support member to accommodate different types of flow cones. Simultaneously, when the grout begins to flow out of the flow cone and first blocks the infrared beam of the infrared sensor, the infrared signal triggers an interrupt in the microprocessor, and the timer starts. When the grout completely stops flowing and the infrared beam recovers, the interrupt is triggered again, and the timer stops. This effectively improves the measurement accuracy of the grout flow time. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] To address the technical problems in existing technologies, such as the lack of adjustable supports, inapplicability to different types of flow cones, and low accuracy in manually recording flow time as the slurry flows out of the flow cone under its own weight, this solution provides a support device for detecting the flowability of slurry. This device is adaptable to different types of flow cones and improves the accuracy of slurry flow time measurement.

[0020] Please see Figures 1-5 , Figures 1-5A support device for detecting the flowability of grouting material according to one embodiment of the present invention includes a base 1, a support member 2, an adjusting member 3, and a measuring member 4. The support member 2 is mounted on the base 1 and has a through hole 22a. The adjusting member 3 is connected to the support member 2 and has a first state fixed to the support member 2 and a second state sliding relative to the support member 2. The adjusting member 3 has a limiting hole 32a, which corresponds to the through hole 22a below. The measuring member 4 includes an infrared sensor 41, a microprocessor 42, and a timer 43. The infrared sensor 41 is mounted on the support member 2 and located on one side of the through hole 22a. The microprocessor 42 is electrically connected to the infrared sensor 41 and the timer 43 respectively.

[0021] In actual use, depending on the model of the flow cone A, in the second state, the drive adjustment component 3 moves relative to the support component 2 to adjust the distance between the limiting hole 32a and the through hole 22a, so that when the flow cone A is inserted into the limiting hole 32a, the discharge port at the bottom of the flow cone A can extend into the through hole 22a. When the slurry flows out from the discharge port of the flow cone A, when the slurry begins to flow out and first blocks the infrared beam of the infrared sensor, the infrared signal triggers the microprocessor interrupt, the timer starts, and when the slurry completely stops flowing and the infrared beam recovers, the interrupt is triggered again, the timer stops, and the timer can accurately measure the time when the slurry begins to flow out and completely flows out.

[0022] It should be noted that the support member 2 and the adjusting member 3 are not limited to a specific structure. In one embodiment, the support member 2 includes at least two support tubes 21 and a base plate 22. The lower ends of the two support tubes 21 are fixedly connected to the base body 1. The base plate 22 is connected to the two support tubes 21. The base plate 22 has a through hole 22a. The infrared sensor 41 is installed on the base plate 22. The side wall of the upper end of the support tube 21 has a positioning hole. The adjusting member 3 includes at least two adjusting rods 31, a top plate 32, and two locking bolts 33. The lower ends of the two adjusting rods 31 are slidably inserted into the two support tubes 21. The upper ends of the two adjusting rods 31 are fixedly connected to the top plate 32. The top plate 32 has a limiting hole 32a. The adjusting rods 31 have a plurality of threaded holes 31a spaced apart. The locking bolts 33 pass through the positioning holes 21a and can be screwed into each of the threaded holes 31a respectively.

[0023] Understandably, when it is necessary to adjust the distance between the through hole 22a and the limiting hole 32a, the two locking bolts 33 can be rotated to separate the locking bolts 33 from the threaded hole 31a, thereby adjusting the depth of the adjusting rod 31 inserted into the support tube 21; wherein, the flow cone A is conical, and the inner diameter of the limiting hole 32a is 3-6 times the inner diameter of the through hole 22a, preferably, the inner diameter of the limiting hole 32a is 5 times the inner diameter of the through hole 22a.

[0024] Specifically, the distance between the centers of two adjacent threaded holes 31a is 10mm, and the adjusting rod 31 has a total of 10 threaded holes 31a along its length. When the locking bolt 33 passes through the positioning hole 21a and engages with one of the threaded holes 31a, it can restrict the relative sliding of the support tube 21 and the adjusting rod 31.

[0025] It should be noted that, in one embodiment, the length of the adjusting rod 31 is greater than the length of the support tube 21, and the outer diameter of the adjusting rod 31 is slightly smaller than the inner diameter of the support tube 21, so as to ensure that the adjusting rod 31 can be slidably inserted into the support tube 21.

[0026] In one embodiment, the base 1, the bottom plate 22, and the top plate 32 are all disc-shaped, wherein the through hole 22a and the limiting hole 32a are both circular holes, and the circular holes can better fit the flow cone.

[0027] It should be noted that a space for placing a mixing pot is formed between the base 1 and the bottom plate 22, and an installation space for placing a flow cone is formed between the bottom plate 22 and the top plate 32. In use, the flow cone is inserted into the limiting hole 32a to position the flow cone in the installation space, and the mixing pot is placed on the bottom plate 22 so that the mixing pot is set in the installation space, ensuring that the slurry flowing out of the flow cone can fall into the mixing pot.

[0028] The microprocessor 42 is model STM32H743VIH6, and the timer is an electronic stopwatch.

[0029] In addition, based on the above solution, in order to ensure that the base can be placed horizontally, a plurality of leveling components 5 are also included. The plurality of leveling components 5 are all installed on the base 1 and are used to adjust the horizontality of the base 1.

[0030] It should be noted that the leveling component 5 is not limited to a specific structure. Specifically, the leveling component 5 is an adjusting bolt, and the base 1 is provided with multiple threaded adjusting holes. The adjusting bolt is threadedly rotatably connected to the threaded adjusting holes.

[0031] Specifically, based on the above scheme, a level 6 is also included. The level 6 is installed on the base 1, and the operator can observe and determine whether the base 1 is placed horizontally through the level 6.

[0032] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
