Description

Technical Field

[0001] The utility model relates to the field of intelligent grouting process equipment, is applied in the grouting industry, and specifically relates to a weighing type grouting system controller. Background Art

[0002] In the current foundation treatment and building reinforcement process, grouting technology is widely used as a key means to fill foundation holes, cracks and strengthen the connection gaps of building structures, aiming to achieve effective anti-seepage and enhance the stability and integrity of the structure. The core of this technology lies in the precise control of the injection of slurry to ensure that the slurry can fully penetrate into the target area while ensuring the quality and efficiency of grouting. The management of slurry consistency is particularly critical: although thin slurry has good fluidity, it is easy to cause waste and may be separated from the base due to large solidification shrinkage; on the contrary, although thick slurry has excellent bonding properties, it is difficult to penetrate small cracks. Therefore, in practice, a strategy of from thin to thick is usually adopted, and grouting is performed in stages in order to achieve the best grouting effect.

[0003] However, in actual operation, the realization of this refined grouting process faces technical challenges, especially in the dynamic adjustment of slurry concentration. Existing grouting systems mostly rely on slurry mixing barrels equipped with weighing sensors to monitor and control slurry density, and then adjust the opening and closing of water valves and slurry valves through remote controllers to adapt to different requirements for slurry consistency during the grouting process. Although this method is feasible in theory, it exposes a series of problems in practical applications, including but not limited to: complex pipeline and line layout, which not only increases the difficulty of installation and maintenance, but also may cause unstable signal transmission due to long lines; the wiring and maintenance of weighing sensors are cumbersome, and once a failure occurs, the repair or replacement process is time-consuming and costly; in addition, the remote placement of the controller also brings inconvenience to the initial calibration and subsequent debugging of the equipment, affecting the overall operation efficiency and system reliability.

[0004] In view of the above technical limitations, there is an urgent need for a more efficient, convenient and maintenance-friendly grouting control system to optimize the slurry ratio adjustment process, simplify the on-site layout, improve the accuracy and efficiency of grouting operations, and reduce maintenance costs, so as to meet the needs of modern engineering for high-quality grouting technology. Utility Model Content

[0005] Based on the current status of the background technology, in order to solve the limitations of the existing grouting system in the remote structure layout, the utility model proposes a weighing type grouting system controller; the controller not only has the basic functions of adjusting the grouting ratio and feedback adjusting the slurry density, but also improves the installation position and convenience from the structural point of view, making the pipeline layout more convenient and saving production and maintenance costs.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] like Figure 1 As shown, a weighing type slurry mixing system controller includes a chassis bottom shell 2, a measuring component mounting plate 21, a control valve group 24, a signal acquisition module 25 and a main board 27; the chassis bottom shell 2 is fixedly mounted on a slurry mixing barrel (not shown in the figure); the measuring component mounting plate 21 is arranged inside the chassis bottom shell 2, and the measuring component mounting plate 21 divides the internal area of ​​the chassis bottom shell 2 into an upper control unit area and a lower signal access unit area; the control valve group 24, the signal acquisition module 25 and the main board 27 are all arranged in the control unit area; the measuring component mounting plate 21 is provided with a telecommunication interface 211 and an air source interface 212.

[0032] During the grouting process, the wiring of the external sensor can pass through the outer wall of the signal access unit area of ​​the chassis bottom shell 2, and connect to the telecommunication interface 211 on the measuring component mounting plate 21; so that the signal acquisition module 25 in the controller can obtain various parameters such as those measured by weighing sensors and temperature sensors after being electrically connected to the corresponding interface. These real-time collected data can be fed back to the main board 27, thereby realizing the basic automatic grouting function. The same is true for the access to the external air source. On this basis, the procedures involved in data collection and feedback are all mature technologies in this field, and the control requirements for the proportion, mixing, etc. of the grouting process are also well known to those skilled in the art. When the controller is actually applied, it can be set as needed, and no further details will be given here.

[0033] As a preferred embodiment of this embodiment, Figure 2 As shown, the controller also includes a chassis door 1, which is arranged on the front of the chassis bottom shell 2; a water retaining groove (not shown in the figure) is arranged on the front of the chassis bottom shell 2, and the position of the water retaining groove corresponds to the contact position of the chassis door 1 on the front of the chassis bottom shell 2. At the same time, a sealing strip (not shown in the figure) is pasted on the surface of the side of the chassis door 1 facing the chassis bottom shell 2, and the pasting position of the sealing strip matches the setting position of the water retaining groove. The cooperation between the water retaining groove and the sealing strip can effectively prevent external water from entering the chassis, especially entering the control unit area of ​​the chassis bottom shell 2. The presence of the measuring component mounting plate 21 can also effectively prevent splashing mud from splashing into the control unit area.

[0034] In this embodiment, matching lock components are also provided on the chassis door 1 and the chassis bottom shell 2. When the controller is in use, the chassis door 1 is closed, and the lock component locks it with the chassis bottom shell 2 to prevent direct adjustment of internal devices or wiring during use, and the closed and locked states of the chassis door 1 can be marked by the seal.

[0035] As a preferred embodiment of this embodiment, Figure 2 As shown, the chassis bottom shell 2 is fixedly mounted on the slurry mixing barrel through the mounting frame 3, and the mounting mode of the chassis bottom shell 2 on the slurry mixing barrel is wall-mounted or vertically mounted. For wall-mounted or vertically mounted, mounting holes (not shown in the figure) are opened at the four corners of the back or bottom surface of the chassis bottom shell 2, and the mounting frame 3 is detachably connected to the chassis bottom shell 2 through the mounting holes.

[0036] To further improve the functional structure of the controller of this embodiment, in this embodiment, the controller further includes a sensor 22, a cleaning valve 23 and a pressure regulating valve 26; the pressure regulating valve 26 is arranged in the control unit area; the sensor 22 and the cleaning valve 23 are installed on the side wall of the control unit area of ​​the chassis bottom shell 2. The cleaning valve 23 and the pressure regulating valve 26 respectively realize the corresponding functional requirements in the slurry mixing process.

[0038] As a preferred embodiment of this embodiment, the control valve group 24 is installed on the upper position of the panel of the mounting plate 28, the signal acquisition module 25 is installed on the left middle position of the panel of the mounting plate 28, the pressure regulating valve 26 is installed on the right middle position of the panel of the mounting plate 28, and the main board 27 is installed on the left lower position of the panel of the mounting plate 28.

[0039] This design ensures that both circuit control and gas path control are located in the control unit area, with the circuit area on the left and the gas path area on the right, which facilitates the subsequent replacement of electrical components and reduces mutual interference between electrical components.

[0040] As a preferred embodiment of this invention, it is also in line with the circuit and gas path layout in the control unit area, such as Figure 3 As shown, the interface directions of the telecommunication interface 211 and the gas source interface 212 are both vertical; after the two interfaces are marked accordingly, since during use, whether the controller is mounted on a wall or erected upright, the chassis bottom shell 2 is used vertically as a whole, the corresponding interface can be seen intuitively to avoid wrong connection.
