Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a building grouting device. Background Art

[0002] Grouting is a civil construction process that fills the gaps and cracks of the object to be constructed with solidifying materials. Its main purpose is to improve the overall stability and strength of the object to be constructed. Construction objects that usually contain holes and gaps, such as houses, bridges, roads, tunnels, construction foundations, etc., can all use this method to increase service life and maintain strength. The construction method is to use a special grouting machine to spray and inject the corresponding solidifying material (usually cement) into the gap to bond and increase strength.

[0003] However, during the construction process, the types and distribution of cracks in the construction objects are often irregular. Due to the limitations of the construction scope and the volume of the grouting machine, it is difficult for conventional grouting machines to carry out grouting construction on all cracks and holes. Special manual grouting equipment is required to carry out supplementary construction on locations where the grouting machine cannot construct. In other words, special manual grouting equipment is also required while preparing the grouting machine, which increases the construction cost. Utility Model Content

[0010] The grouting chamber interface can be connected to the connecting pipe, and it can also be connected to the storage tank filled with slurry;

[0011] A driving rotor pointing to the grouting port and surrounded by threaded blades is arranged inside the grouting chamber, and a driving motor with an output end connected to the driving rotor is arranged outside the grouting device, and the driving motor can enable the driving rotor to transport the slurry inside the grouting chamber to the grouting port and discharge it from the grouting chamber.

[0012] An implementation manner of the utility model is that a fixing interface is arranged on the grouting device, and when the grouting device is located in the fixing groove, a fixing bolt is arranged in the fixing interface to fix the grouting device in the fixing groove.

[0013] An implementation manner of the utility model is that a grouting nozzle is detachably provided on the grouting port, and the grouting nozzle comprises a part connected to the grouting port and a hose part which can be bent arbitrarily.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the embodiments and drawings.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0026] Example:

[0027] See also Figure 1, a building grouting device, comprising a movable base 1, and a fixed groove 3 and a piston tank 5 arranged on the base 1, wherein the piston tank 5 is provided with at least two groups of connection ports connected to the outside, one group of connection ports of the piston tank 5 is connected with a connecting pipe 8, and the other group of connection ports is connected with a grouting pipe 10 connected with an external slurry source, and the grouting pipe 10 is provided with a grouting pipe check valve 11 that only allows slurry to flow from the external slurry source to the piston tank 5, and the piston tank 5 is provided with a piston rod 7 that can reciprocate inside the piston tank 5 driven by a piston power source 6, and the grouting device 4 is detachably arranged in the fixed groove 3, and the grouting device 4 is provided with a grouting port 43 for spraying slurry, wherein the grouting device 4 is connected to the piston tank 5 by a detachable connecting pipe 8, and the connecting pipe 8 is also provided with a connecting pipe check valve 9 that only allows slurry to flow from the piston tank 5 to the grouting device 4. In this embodiment, The piston power source 6 adopts an electric cylinder. When the electric cylinder drives the piston rod 7 to reciprocate inside the piston tank 5, it will cause the internal space of the piston tank 5 to contract and expand periodically, thereby producing a suction and extrusion effect. Since the grouting pipe 10 is connected to an external slurry source, when the piston rod 7 moves toward the electric cylinder, it will produce a suction effect in the piston tank 5, and the slurry filling the gap from the outside will be sucked into the piston tank 5 along the grouting pipe 10, while the slurry in the connecting pipe 8 will not be sucked into the piston tank 5 under the action of the connecting pipe check valve 9. Afterwards, when the piston rod 7 moves away from the electric cylinder, it will be affected by the grouting pipe check valve 11 on the grouting pipe 10, and it will press the slurry along the connecting pipe into the grouting device 4, and the grouting device 4 will further distribute the slurry to the gap that needs grouting. Since the piston rod 7 has the characteristics of continuous operation and large force, conventional grouting operations can be achieved.

[0028] See also Figure 2 In this embodiment, the grouting device 4 includes a grouting chamber 41 therein, and a grouting port 43 horizontally arranged on the grouting device 4 and connected to the grouting chamber 41, wherein a grouting chamber interface 42 connected to the grouting chamber 41 and at least two sets of handles 47 are arranged on the top of the grouting device 4, and a stop valve 44 is arranged on the grouting port 43. The grouting chamber interface 42 can be connected to the connecting pipe 8, and it can also be connected to the storage tank 49 filled with slurry. The slurry squeezed into the grouting chamber 41 by the connecting pipe 8 will continue to be squeezed to the grouting port 43, thereby realizing the directional injection of the slurry.

[0029] Among them, a driving rotor 45 pointing to the grouting port 43 and surrounded by threaded blades is arranged inside the grouting chamber 41, and a driving motor 46 whose output end is connected to the driving rotor 45 is arranged outside the grouting device 4, and the driving motor 46 can enable the driving rotor 45 to transport the slurry inside the grouting chamber 41 to the grouting port 43 and discharge it from the grouting chamber 41. While the slurry is squeezed into the grouting chamber 41 by the connecting pipe 8, the driving motor 46 can also be started to drive the driving rotor 45 to rotate. The driving device 45 can refer to the threaded blade conveying device in the prior art. On the one hand, it can re-stir the slurry squeezed into the grouting chamber 41 to make it more uniform. On the other hand, the driving rotor 45 has a conveying function, which can further provide power for the directional injection of the slurry, thereby improving the grouting effect.

[0030] When the grouting device 4 needs to be removed for use, after stopping the grouting of the piston tank 5, the connecting pipe 8 is replaced with a storage tank 49 filled with slurry. The storage tank 49 can refer to the prior art and adopt a tank body with an interface that can match the grouting chamber interface 42 and has a switch. The grouting device 4 is then removed. After removal, the user can hold the handle to move the grouting device. When it is moved to the position where manual grouting is required, the stop valve 44 and the switch on the storage tank 49 are opened, and the drive motor 46 is started to guide the drive rotor 45 to rotate, and the slurry introduced into the grouting chamber 41 by the storage tank 49 is transported to the grouting port 43. At the same time, the slurry in the storage tank 49 also has its own weight. Under the combined effect of the conveying effect, sufficient power is provided for grouting, thereby achieving accurate grouting at the artificial grouting position.

[0031] See also Figure 1 , Figure 2 In this embodiment, a fixing interface 48 is provided on the grouting device 4. When the grouting device 4 is located in the fixing groove 3, a fixing bolt 13 is provided in the fixing interface 48 to fix the grouting device 4 in the fixing groove 3. The way in which the fixing bolt 13 fixes the grouting device 4 in the fixing groove 3 can refer to the prior art, that is, the fixing bolt 13 passes through the fixing groove 3 and extends into the fixing interface 48 to achieve fixation. Obviously, a thread matching the fixing bolt 13 needs to be provided in the fixing interface 48.

[0032] like Figure 1 As shown, in some embodiments, a grouting nozzle 12 is detachably provided on the grouting port 43, and the grouting nozzle 12 includes a portion connected to the grouting port 43 and a hose portion that can be bent arbitrarily. The portion connected to the grouting port 43 can be fixed by a threaded connection method commonly used in the prior art. Similarly, the prior art can be referred to. When the grouting device 4 is fixedly arranged in the fixing groove 3 for conventional grouting construction, the spraying position of the slurry can be controlled by adjusting the position of the hose.

[0033] In this embodiment, a plurality of sets of universal wheels 2 for support are arranged at the bottom of the base 1, so that the whole device can move in any direction.

[0034] When the utility model is used, the device is moved as a whole to the vicinity of the position to be grouting. If conventional grouting is required, the device is moved as follows. Figure 1 The structure shown is connected to the assembly device, and the grouting pipe 10 is connected to the external slurry source, and then the corresponding switch is turned on, the piston power source 6 is started to suck and squeeze the external slurry into the grouting device 4, and the drive motor 46 is started as needed to further provide stirring and driving force for the slurry entering the grouting device 4, so that the slurry is sprayed out from the position specified by the grouting nozzle 12 to complete the conventional grouting operation.

[0035] When performing manual grouting operations on locations that are difficult to reach with conventional grouting, close all valves and replace the device connected to the grouting chamber interface 42 with a storage tank 49 filled with slurry. Then remove the grouting device 4 from the fixed groove 3, remove the grouting nozzle 12, start the drive motor 46, and turn on the switch and stop valve 44 on the storage tank 49. In this way, the slurry can be sprayed to locations that are difficult to reach with conventional grouting while holding the grouting device 4, thereby achieving effective grouting for gaps of different ranges.

[0036] In the description of the present invention, it should be pointed out that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and should not be understood as a limitation on the present invention.

[0037] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the embodiment of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
