Description

Technical Field

[0001] This utility model relates to testing equipment, and in particular to a rapid detector for the water-cement ratio of grout in ducts. Background Technology

[0002] The quality of the grout directly affects the anchorage performance of box girders and is a key aspect of bridge construction quality control. Currently, in engineering practice, grout quality mainly relies on the grouting machine's own weighing system to control the water-cement ratio and on testing the strength of the components after construction. There is a lack of rapid and precise quality control methods that can be directly applied before or during construction.

[0003] In existing technologies, there is a lack of effective pre-verification methods for the grouting capacity (including metering accuracy and mixing effect) of grouting machines. It is difficult to determine in advance whether the equipment can meet the grout flow rate requirements under the set water-cement ratio, which can easily lead to the use of unqualified equipment in construction. At the same time, there is a lack of convenient detection methods for the dynamic control of the grout water-cement ratio during construction, making it impossible to monitor the stability of grout quality in real time, which may cause potential project quality problems.

[0004] Furthermore, traditional grout testing equipment often suffers from limitations such as limited functionality, cumbersome operation, and difficulty in cleaning after testing, with residual grout potentially affecting the accuracy of subsequent tests. Therefore, there is an urgent need for a quality detector that integrates grout density testing and flow rate verification functions, and features a convenient cleaning structure. This would enable pre-verification of grouting equipment performance and efficient control of grout quality during construction, filling a gap in existing technology.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated to create a rapid detector for the water-cement ratio of grout in ducts, making it more valuable for industrial applications. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a rapid detector for the water-cement ratio of grout in ducts.

[0007] This utility model discloses a rapid water-cement ratio detector for grouting slurry, comprising a base, an upwardly extending bracket mounted on the upper side of the base, a rotatable swing shaft mounted on the upper part of the bracket via a shaft, an installation platform with a through hole in the middle of the swing shaft, a weighing platform with a through hole in the middle above the installation platform, and a material bottle mounted on the upper part of the weighing platform via a clamp, the material bottle being used to hold the grouting slurry.

[0008] This rapid water-cement ratio detector for grouting has an upward-extending support on its base. A swing shaft is rotatably mounted on the support via a shaft. A mounting platform with a through hole is installed in the middle of the swing shaft. A weighing platform with a through hole is set above the mounting platform. A container for holding the grouting slurry is securely mounted on the weighing platform with clamps. During testing, a fixed volume container is first filled with grouting slurry. The weight of the filled container is measured by the weighing platform. The measured weight data is then compared with a preset parameter comparison table to quickly obtain the relevant quality parameters of the slurry, achieving efficient control over the slurry quality.

[0009] Furthermore, a water pump bracket is fixed at the top of one side of the support, and a rinsing water pump is installed on the upper end of the water pump bracket. One end of the rinsing water pump is connected to the water source tank through a pipeline, and a corrugated pipe is installed at the outlet of the rinsing water pump. The corrugated pipe can extend into the opening at the top of the material bottle.

[0010] A water pump bracket is fixed to the top of one side of the support. A flushing water pump is installed on the upper end of the water pump bracket. The flushing water pump is connected to the water source tank through a pipeline. Its outlet is connected to a corrugated pipe that can be flexibly adjusted. The corrugated pipe can extend into the opening at the top of the material bottle. In conjunction with the swing shaft, it drives the material bottle to tilt. Through the linkage of water filling and swinging, the inside of the material bottle is thoroughly flushed to avoid residual slurry from affecting the accuracy of subsequent testing.

[0011] Furthermore, a water inlet channel is fixed between the supports, and a drain pipe is connected to the bottom of the water inlet channel. The drain pipe extends from the side wall of the base, and the water inlet channel is funnel-shaped.

[0012] A funnel-shaped water inlet trough is fixed between the supports, and a drain pipe is connected to the bottom of the water inlet trough. The drain pipe extends outward from the side wall of the base and can quickly collect the wastewater and residual slurry flowing out during the washing of the material bottle. The waste liquid is smoothly discharged into the drain pipe through the guiding effect of the funnel-shaped structure, so as to achieve centralized discharge of sewage and clean maintenance of the site environment.

[0013] Furthermore, a filter screen is placed inside the water intake channel.

[0014] The water inlet tank is equipped with a filter screen, which filters the waste liquid flowing into the water inlet tank after rinsing the material bottle, intercepts the slurry residue to prevent blockage of the drain pipe, and ensures the smooth flow of sewage.

[0015] Furthermore, a driven pulley is fixed to one side of the swing shaft after passing through the bracket, a drive motor is fixed to the inside of the bracket, the output shaft of the drive motor is installed with a drive pulley after passing through the bracket, and a belt is installed between the driven pulley and the drive pulley.

[0016] One side of the swing shaft passes through the bracket and is fixedly connected to the driven pulley. The drive motor is installed inside the bracket. The output shaft of the drive motor passes through the bracket and is fitted with the drive pulley. The driven pulley and the drive pulley are connected by a belt. Starting the drive motor will drive the belt to drive the driven pulley, thereby driving the swing shaft to rotate smoothly, providing stable power for slurry pouring and bottle rinsing.

[0017] Furthermore, the clamps are divided into left clamps and right clamps. The right clamp is fixedly connected to the weighing platform, and the left clamp and right clamp are fixedly connected by bolts and nuts. The inner sides of the left clamp and right clamp are covered with a soft protective layer.

[0018] The clamp consists of a left clamp and a right clamp. The right clamp is fixedly connected to the weighing platform, while the left and right clamps are securely spliced ​​together with bolts and nuts. Both clamps have a soft protective layer pasted on their inner sides, which can not only firmly fix the material bottle to prevent displacement during testing or rinsing, but also prevent damage caused by direct friction between the material bottle and the clamp through the soft protective layer, thus ensuring the integrity of the material bottle and the stability of the testing.

[0019] By means of the above-described solution, the present invention has at least the following advantages:

[0020] 1. Highly efficient and accurate testing to meet the needs of full-process quality control: By using a fixed-volume material bottle and a weighing platform, the quality parameters of the grout can be quickly obtained by comparing the weight with the parameter table. This not only realizes the pre-construction verification of the grouting equipment's grouting capacity, but also enables dynamic control of the grout's water-cement ratio during construction, effectively preventing the use of unqualified equipment or inferior grout from affecting the project quality.

[0021] 2. Convenient and thorough cleaning, ensuring continuous and accurate testing: The flushing water pump, corrugated pipe and swing shaft are linked, which can achieve deep cleaning of the inside of the material bottle by filling water and swinging. Combined with the guiding and filtering effect of the funnel-shaped water inlet and the filter screen, it can not only avoid the interference of residual slurry with subsequent test results, but also prevent residue from clogging the drain pipe, ensuring centralized discharge of sewage and a clean on-site environment.

[0022] 3. Stable and reliable structure, excellent user experience: The drive motor drives the swing shaft to rotate smoothly through belt transmission, providing stable power for slurry pouring and rinsing; the splicing design of the left and right clamps, combined with the inner soft protective layer, not only ensures that the material bottle is firmly fixed without displacement, but also avoids wear on the material bottle, extending the service life of the equipment. At the same time, the overall structure is easy to operate, reducing the difficulty of use for on-site technicians.

[0023] 4. Strong functional integration, filling a technological gap: The integrated design of slurry density testing, equipment performance verification, convenient cleaning, and sewage treatment solves the pain points of traditional testing equipment, such as single function, cumbersome operation, and inconvenient cleaning. It significantly improves the efficiency of construction quality control and has high industrial application value and promotion prospects.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] See Figure 1First, the grout to be tested is injected into a fixed-volume bottle 7 and filled. The bottle 7 is then securely mounted on a weighing platform 5 using clamps 6. The weighing platform 5 is positioned above an installation platform 4, which is fixed in the middle of a swing shaft 3. The swing shaft 3 is movably mounted on a bracket 2 extending from the upper side of the base 1. The weight of the bottle 7 filled with grout is measured using the weighing platform 5. The measured weight value is then compared with the corresponding parameter table to accurately obtain the relevant quality parameters of the grout. The base 1 and bracket 2 provide stable support, the swing shaft 3 and installation platform 4 ensure the stable installation of the weighing platform 5, and the clamps 6 ensure that the bottle 7 does not shift during the weighing process. The combination of the fixed-volume bottle 7 and the weighing platform 5 enables the rapid and accurate acquisition of grout quality parameters. The operation is simple and can directly serve the equipment verification before construction and the grout quality control during construction.

[0032] After the grouting slurry test is completed, the flushing water pump 9, which is connected to the water source tank through a pipeline, is fixed to the top of one side of the bracket 2 using the water pump bracket 8. The corrugated pipe 10 installed at the outlet of the flushing water pump 9 is adjusted and inserted into the top opening of the material bottle 7. The flushing water pump 9 is started, so that water in the water source tank is injected into the material bottle 7 through the pipeline, the flushing water pump 9, and the corrugated pipe 10. The swing shaft 3 drives the material bottle 7 to swing, flushing the residual slurry inside the material bottle 7. The water pump bracket 8 provides a stable installation base for the flushing water pump 9, and the corrugated pipe 10 can be flexibly adjusted to ensure that the flushing water is accurately injected into the material bottle 7. The flushing water pump 9 can continuously provide a sufficient flushing water source to achieve rapid and thorough cleaning of the inside of the material bottle 7, avoiding residual slurry from affecting the accuracy of subsequent tests. At the same time, the operation is convenient, and the cleaning operation can be completed without disassembling the material bottle 7, improving the testing efficiency.

[0033] During the rinsing process of the material bottle 7, the funnel-shaped water inlet 11 fixed between the supports 2 collects the rinsing wastewater and residual slurry flowing out of the material bottle 7. The funnel-shaped structure of the water inlet 11 enables the rapid collection and guidance of the waste liquid, allowing it to flow smoothly into the drain pipe 12 connected to the bottom of the water inlet 11. The waste liquid is then discharged through the drain pipe 12, which extends from the side wall of the base 1. The advantages of this process are that the funnel-shaped water inlet 11 can maximize the collection of rinsing waste liquid, avoiding wastewater splashing and polluting the site environment. The drain pipe 12 enables directional discharge of waste liquid, eliminating the need for additional cleaning and reducing the intensity of on-site operations. At the same time, the support 2's fixation of the water inlet 11 ensures the stability of the drainage process. The overall structure is compact and does not affect the normal operation of other components of the testing equipment, ensuring the continuity of testing and cleaning operations.

[0034] See Figure 2Before the waste liquid generated from rinsing the material bottle 7 flows into the funnel-shaped water inlet trough 11 fixed between the support 2, the filter screen plate 13 is placed in the water inlet trough 11. When the waste liquid carrying slurry solid waste enters the water inlet trough 11, the filter screen plate 13 will filter the waste liquid and separate the solid waste. The filtered waste liquid is then discharged from the side wall of the base 1 through the drain pipe 12 connected to the bottom of the water inlet trough 11. After use, the filter screen plate 13 can be directly removed from the water inlet trough 11 for separate cleaning. The filter screen plate 13 can effectively intercept the slurry solid waste in the waste liquid, prevent it from clogging the drain pipe 12, ensure unobstructed drainage, and the removable design of the filter screen plate 13 makes subsequent cleaning operations simple and efficient, without the need for complicated disassembly of the water inlet trough 11, which reduces the maintenance difficulty and keeps the inside of the water inlet trough 11 clean, ensuring long-term stable operation of the equipment.

[0035] When it is necessary to rinse or drain the bottle 7, the drive motor 15 fixed inside the bracket 2 is started. The output shaft of the drive motor 15 passes through the bracket 2 and drives the drive pulley 16 mounted on it to rotate. The drive pulley 16 is linked to the driven pulley 14 through the belt 17 installed therewith. The driven pulley 14 is fixedly connected to the swing shaft 3 passing through the bracket 2, thereby driving the swing shaft 3 to rotate smoothly. When the swing shaft 3 rotates, it will drive the bottle 7 fixed by the mounting platform 4, weighing platform 5 and clamp 6 above to swing synchronously, improving the rinsing efficiency of the water in the bottle and enhancing the cleaning effect. After cleaning, the swing shaft 3 can be controlled by the drive motor 15 to invert and stop the material bottle 7, which helps to quickly drain the cleaning water. The drive motor 15 provides stable power, and through the transmission cooperation of the drive pulley 16, belt 17 and driven pulley 14, the swing shaft 3 can be rotated smoothly and controllably. This not only improves the rinsing effect of the material bottle 7, but also efficiently completes the draining of the cleaning water. No manual operation is required, reducing labor intensity. At the same time, the transmission structure is stable and reliable, which can ensure the safety of the material bottle 7 during the swinging and inversion process, and avoid the accumulation of slurry residue or cleaning water affecting subsequent testing.

[0036] When installing the material bottle 7, first secure the right clamp 19 to the weighing platform 5, then place the material bottle 7 inside the right clamp 19. After closing the left clamp 18, tighten the left clamp 18 and right clamp 19 together with bolts and nuts. The soft protective layer attached to the inner sides of both clamps adheres to the outer wall of the material bottle 7 to complete the fixation. During testing or cleaning, the fixing of the right clamp 19, combined with the tightening of the left clamp 18, ensures that the material bottle 7 is placed stably. When the swing shaft 3 drives the material bottle 7 to swing to improve the flushing efficiency of the water inside the bottle, or after cleaning, the material bottle 7 is inverted and stopped. To ensure the material bottle 7 remains in place and free from impacts during the drainage of cleaning water, the detachable design of the left clamp 18 and right clamp 19 facilitates quick installation and removal of the material bottle 7. The bolt and nut connection ensures the fixing strength. The soft protective layer not only prevents damage caused by direct friction between the material bottle 7 and the clamp 6, but also enhances the fit and improves stability. The fixed connection between the right clamp 19 and the weighing platform 5 further ensures the stability of the material bottle 7 during swinging, inversion and other actions, preventing the material bottle 7 from affecting the detection accuracy or cleaning effect due to loosening, while also extending the service life of the material bottle 7.

[0037] The right clamp 19 and the weighing platform 5 can be integrated or welded together.
