Description

Technical Field

[0001] This utility model relates to the field of concrete grouting technology, and more specifically to a concrete grouting device. Background Technology

[0002] Grouting is the process of injecting certain solidifying materials, such as cement, lime, or other chemical materials, into the foundation soil within a certain range to fill cracks and pores in the soil, prevent foundation leakage, and improve the integrity, strength, and stiffness of the soil. In water-retaining structures such as sluices, dams, and dikes, grouting is commonly used to construct foundation seepage barriers and is a major foundation treatment measure for hydraulic structures.

[0003] However, existing concrete grouting devices have fixed grouting nozzles that cannot be flexibly adjusted, and the devices themselves are quite large, requiring a moving mechanism to adjust the nozzle position, which is very cumbersome. Therefore, this paper studies and improves upon the existing structure and its shortcomings to provide a concrete grouting device with greater practical value. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete grouting device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a concrete grouting device, including a base plate, casters, and a handrail. The handrail is fixedly installed at one top end of the base plate, and casters are fixedly installed around the bottom perimeter of the base plate. A mounting base is fixedly installed at the top end of the base plate away from the handrail. A first motor, which is a stepper motor, is installed at the bottom of the mounting base. A first connecting rod is fixedly installed at the output end of the first motor. A placement platform is fixedly installed at the top of the first connecting rod. A mounting block is fixedly installed at the top of the placement platform. A grouting nozzle is installed inside the mounting block. A telescopic tube is fixedly installed at one end of the grouting nozzle. In actual use, with the above structure, when grouting is required, the operator can push the entire device to the designated position using the handrail, and then adjust the angle of the grouting nozzle by controlling the operation of the first motor to align it with the area requiring grouting. Simultaneously, the length of the telescopic tube changes during rotation, ensuring that the grouting nozzle accurately reaches the grouting location.

[0006] Furthermore, the top of the mounting base is provided with a sliding groove, and a slider is slidably installed inside the sliding groove. A support rod is fixedly installed on the top of the slider, and the top of the support rod is fixedly connected to the bottom of the placement platform. In actual use, the above structure serves to guide the placement platform to rotate when the grouting nozzle is adjusted in angle.

[0007] Furthermore, a material cylinder is installed on the top of the base plate via four support columns. The top of the material cylinder has a feed inlet, and the bottom of the material cylinder has a second motor, which is a stepper motor. A second connecting rod is fixedly installed at the output end of the second motor. Several connecting plates are fixedly installed on the outer surface of the second connecting rod, and several through slots are formed on the outer surface of the connecting plates. A connecting pipe is installed at one end of the material cylinder, and the connecting pipe is connected to the telescopic pipe via a delivery pump. In actual use, with the above structure, before the grouting operation begins, the operator adds an appropriate amount of concrete material into the material cylinder through the feed inlet. When grouting is required, the second motor starts, driving the second connecting rod and its connecting plates and mixing elements to rotate. This rotation helps prevent the concrete at the bottom of the material cylinder from solidifying due to prolonged static contact. The delivery pump starts, pumping the concrete material in the material cylinder to the telescopic pipe through the connecting pipe, and then delivering it to the grouting nozzle for grouting, effectively preventing the solidification of the bottom concrete.

[0008] Furthermore, a scraper is fixedly installed on the outer surface of the second connecting rod, and the outer surface of the scraper is in contact with the inner wall of the material cylinder. In actual use, with the above structure, when the second motor starts, it drives the second connecting rod and the scraper on it to rotate. The scraper moves with the rotation of the second connecting rod, and its outer surface is in close contact with the inner wall of the material cylinder, thereby scraping off the concrete material adhering to the inner wall of the material cylinder, effectively preventing the concrete from depositing and solidifying on the inner wall of the material cylinder, and maintaining the cleanliness of the material cylinder and the fluidity of the concrete.

[0009] Furthermore, a propeller is mounted on the top of the second connecting rod via a bearing, and the top of the propeller is triangular. In actual use, through the above-mentioned structure, the triangular top design of the propeller enables it to cut and mix concrete materials more effectively when rotating. The rotation of the propeller not only promotes the flow of concrete, but also forms a cyclical mixing process.

[0010] Furthermore, a control box is provided at one top end of the base plate, and the control box contains a battery and a controller.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model is equipped with a first motor, a first connecting rod, a mounting block, a telescopic tube, a grouting nozzle, and a mounting base. With this design, when grouting is required, the operator can push the entire device to the designated position via the handle, and then adjust the angle of the grouting nozzle by controlling the operation of the first motor to align it with the part that needs grouting. At the same time, the length of the telescopic tube will also change during rotation to ensure that the grouting nozzle can accurately reach the grouting point.

[0013] 2. This utility model, by incorporating a material cylinder, connecting pipe, conveying pump, second motor, second connecting rod, and connecting plate, allows the operator to add an appropriate amount of concrete material into the material cylinder through the inlet before grouting begins. When grouting is required, the second motor starts, driving the second connecting rod, its connecting plate, and the mixing element to rotate. This rotation helps prevent the concrete at the bottom of the material cylinder from solidifying due to prolonged static contact. The conveying pump starts, pumping the concrete material from the material cylinder to the telescopic pipe through the connecting pipe, and then conveying it to the grouting nozzle for grouting, effectively preventing the concrete at the bottom from solidifying.

[0020] Example 1: This utility model provides a concrete grouting device, including a base plate 100, casters 110, and a handrail 111. The handrail 111 is fixedly installed at one top end of the base plate 100, and casters 110 are fixedly installed around the bottom of the base plate 100. A mounting base 112 is fixedly installed at the top end of the base plate 100 away from the handrail 111. A first motor 113 is provided at the bottom of the mounting base 112, and the first motor 113 is a stepper motor. A first connecting rod 114 is fixedly installed at the output end of the first motor 113. A placement platform is fixedly installed at the top of the first connecting rod 114. An installation block 115 is fixedly installed at the top of the placement platform. A grouting nozzle 117 is provided inside the installation block 115, and a telescopic tube 116 is fixedly installed at one end of the grouting nozzle 117.

[0021] In practical use, with the above structure, when grouting is required, the operator can push the entire device to the designated position through the handle 111, and then adjust the angle of the grouting nozzle 117 by controlling the operation of the first motor 113 so that it is aligned with the part that needs to be grouted. At the same time, the length of the telescopic tube 116 will also change when rotating, ensuring that the grouting nozzle 117 can accurately reach the grouting point.

[0022] Example 2:

[0023] The difference between Embodiment 2 and Embodiment 1 is that: the top of the mounting base 112 is provided with a sliding groove 120, a slider 119 is slidably installed inside the sliding groove 120, a support rod 118 is fixedly installed on the top of the slider 119, the top of the support rod 118 is fixedly connected to the bottom of the placement platform, a material cylinder 121 is installed on the top of the base plate 100 through four support columns, a feed inlet is provided on the top of the material cylinder 121, and a second motor 124 is provided at the bottom of the material cylinder 121. The second motor 124 is a stepper motor. A second connecting rod 125 is fixedly mounted on the output end of the second motor 124. Several connecting plates 126 are fixedly mounted on the outer surface of the second connecting rod 125. Several through slots are formed on the outer surface of the connecting plates 126.

In actual use, through the arrangement of the material cylinder 121, connecting pipe 122, conveying pump 123, second motor 124, second connecting rod 125 and connecting plate 126, before the grouting operation begins, the operator adds an appropriate amount of concrete material into the material cylinder through the feed port. When grouting is required, the second motor 124 starts, driving the second connecting rod 125 and its connecting plate 126 and stirring element to rotate. This rotation helps to prevent the concrete at the bottom of the material cylinder 121 from solidifying due to prolonged static placement. The conveying pump 123 starts, pumping the concrete material in the material cylinder 121 to the telescopic pipe 116 through the connecting pipe 122, and then conveying it to the grouting nozzle 117 through the telescopic pipe 116 for grouting operation, effectively preventing the solidification of the bottom concrete.
