Description

Technical Field

[0001] This utility model relates to the technical field of civil engineering, and in particular to a construction grouting device. Background Technology

[0002] Grouting is an important process in the construction of tunnels and bridges. It is mainly used to fill voids in concrete structures, improve the overall strength and stability of the structure, and enhance its resistance to erosion and durability.

[0003] In tunnel and bridge construction, grouting devices are widely used for grouting reinforcement to improve structural safety. However, existing grouting devices typically use a fixed method to distribute the grout to ensure uniform coverage of cracks. This fixed grout distribution method is not flexible enough when dealing with cracks of different widths and cannot be adjusted according to the specific shape and width of different cracks. As a result, some specially shaped cracks cannot be fully filled with grout. Utility Model Content

[0004] The present invention aims to provide a grouting device that can adjust the distribution of grout according to the shape of the crack.

[0005] The grouting device according to a first aspect embodiment of the present invention includes:

[0006] A mixing module includes a material cylinder, a power source, and mixing blades. The mixing blades are placed in the material cylinder, and the power source drives the mixing blades to rotate. A discharge pipe is provided at the bottom of the material cylinder.

[0007] The discharge module includes a grouting pump, a grouting pipe, and a discharge assembly, which are connected sequentially. The discharge assembly includes a discharge head, a cover, a baffle, and multiple sealing components. The discharge head is connected to the grouting pipe, and the cover is detachably connected to the discharge head. The cover has multiple discharge holes, and the discharge head has a discharge channel connecting the grouting pipe and the discharge holes. The baffle is located between the cover and the discharge head and has multiple mounting holes, which correspond one-to-one with the discharge holes. The number of sealing components is less than the number of discharge holes. The two ends of each sealing component engage with the mounting hole and the discharge hole, respectively. The discharge area of ​​the cover is changed by controlling the number of sealing components.

[0008] The grouting device according to the embodiments of this utility model has at least the following beneficial effects: the mixing module is used to mix the grout, the grouting pump is used to transport the grout in the cylinder to the discharge head, and for cracks of different shapes, the cap is first removed from the discharge head, and then the number of sealing parts and / or the position of the sealing parts are increased or decreased according to technical requirements. After that, the cap is reinstalled back into the discharge head. Since the discharge holes blocked by the sealing parts cannot discharge normally, the discharge holes not blocked by the sealing parts can discharge normally because they are connected to the discharge channel. Therefore, through the above technical means, the distribution and number of effective discharge holes can correspond to the grouting filling points, thereby ensuring that the grout distribution at each point is uniform during the grouting filling process, ensuring that the grout fully fills the cracks, and thus meeting the grouting requirements of different cracks.

[0009] According to some embodiments of this utility model, in order to avoid misalignment between the baffle and the cover, one of the cover and the baffle is provided with a positioning groove, and the other is provided with a positioning post that engages with the positioning groove.

[0010] According to some embodiments of this utility model, the positioning post and the positioning groove together constitute a positioning structure. Multiple positioning structures are provided, and the cover and the baffle have a unique positional relationship through these multiple positioning structures. When there is only one positioning structure, the cover and the baffle ideally have a unique positional relationship. When there are multiple positioning structures, the layout of the positioning structures must ensure that the cover and the baffle have a unique positional relationship.

[0011] According to some embodiments of this utility model, the cap is threadedly connected to the discharge head, the baffle is larger than the size of the discharge channel, and the baffle abuts against the end face of the discharge head when the cap is tightened. When the cap is tightened to the discharge head, the position of the baffle is also limited, so that the position of the baffle will not be displaced due to the impact of the slurry.

[0012] According to some embodiments of this utility model, in order to facilitate material discharge control, the discharge pipe is equipped with a switching valve.

[0013] According to some embodiments of this utility model, since solenoid valves, ball valves, or gate valves can all realize the opening or closing of the discharge pipe, the switching valve includes at least a solenoid valve, a ball valve, or a gate valve.

[0014] According to some embodiments of the present invention, in order to prevent the slurry from settling at the bottom of the barrel, the stirring blade is provided with a stirring rake extending to the bottom of the barrel.

[0015] According to some embodiments of the present invention, the material cylinder is provided with a stirring zone for accommodating the stirring rake, and the length of the stirring rake accounts for more than 80% of the inner diameter of the stirring zone, so as to effectively improve the stirring effect.

[0016] According to some embodiments of this utility model, a cover is detachably connected to the top of the material cylinder, and the power source is installed on the cover. When material needs to be fed, the cover is opened to expose the material inlet of the material cylinder, and then the mixing material to be mixed is poured into the material cylinder from the inlet. Since the power source is installed on the cover, the stirring blades are also installed on the cover. Therefore, the cover must be reinstalled on the material cylinder before the power source can drive the stirring blades to mix the material in the material cylinder.

[0017] According to some embodiments of the present invention, the grouting device further includes a handcart, which has a bearing surface. The mixing module and the discharge module are both located on the bearing surface, so as to significantly improve construction efficiency and flexibility.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] like Figure 1 As shown, the grouting device according to the first aspect of this utility model includes a handcart 100, a mixing module 200, and a discharge module 300. The handcart 100 can use an existing structure, having a handle 110 and a support plate 120. The bottom surface of the support plate 120 is provided with four rollers 130, two of which are close to the handle 110, and the other two are away from the handle 110. The two rollers 130 close to the handle 110 can be universal wheels with a braking function, while the other two rollers 130 can be ordinary universal wheels. The surface of the support plate 120 is a bearing surface, and the mixing module 200 and the discharge module 300 are both disposed on the bearing surface. The connection between the mixing module 200 and the discharge module 300 and the support plate 120 can be a fixed connection or a movable placement.

[0030] In this embodiment, both the mixing module 200 and the discharge module 300 are fixedly connected to the support plate 120 via connectors to prevent them from falling off the support plate 120 due to vibration, or from changing their positional relationship due to vibration, thus affecting the conveying of slurry. Since both the mixing module 200 and the discharge module 300 are located on the support plate 120 of the handcart 100, the construction position of the grouting device can be changed very flexibly, which helps to improve construction efficiency.

[0031] like Figures 1 to 3 As shown, the discharge module 300 includes a grouting pump 310, a grouting pipe 320, and a discharge assembly 400. The grouting pump 310 can be a BW50 model. The inlet of the grouting pump 310 is connected to the mixing module 200, and the outlet of the grouting pump 310 is connected to the grouting pipe 320. After starting, the grouting pump 310 achieves the intake and discharge of grout based on volume changes. The grouting pipe 320 can be a steel wire reinforced rubber hose, which can freely adjust its spatial position under the action of external force and maintain its spatial position by the steel wire after the external force is removed, which is very suitable for complex construction environments.

[0032] In addition, the discharge assembly 400 includes a discharge head 410, a cover 420, a baffle 430, and multiple sealing components 440. One end of the discharge head 410 is fixedly connected to the grouting pipe 320, and the other end of the discharge head 410 is provided with an external thread. The cover 420 is provided with an internal thread that is threaded to the discharge head 410, so that the cover 420 can be detachably connected to the discharge head 410. The cover 420 is provided with multiple discharge holes 421, and the discharge head 410 is provided with a discharge channel 411 that connects the grouting pipe 320 and the discharge holes 421. Since the cross-sectional shape of the cover 420 and the discharge head 410 is circular, for standardized design, the multiple discharge holes 421 are evenly distributed in the central area of ​​the cover 420, so that the multiple discharge holes 421 are linearly connected to the discharge channel 411. At this time, the end face of the discharge head 410 is directly opposite the edge area of ​​the cover 420. When the grouting pump 310 is started, the grout is sequentially transported from the mixing module 200 to the grouting pump 310, the grouting pipe 320 and the discharge head 410, and finally discharged outward from the multiple discharge holes 421 of the cover 420.

[0033] To meet the grouting requirements of different cracks, a baffle 430 is provided between the cap 420 and the discharge head 410. The baffle 430 has multiple mounting holes 431, which correspond one-to-one with the multiple discharge holes 421. That is, when the cap 420 and the baffle 430 overlap, all mounting holes 431 are connected to all discharge holes 421, and their number and diameter are consistent. Based on this, by engaging the two ends of multiple sealing elements 440 with the mounting holes 431 and the discharge holes 421 respectively, selective closure of the discharge holes 421 can be achieved, thereby changing the discharge area of ​​the cap 420. This utility model does not limit the specific number of sealing elements 440, but the number of sealing elements 440 must be less than the number of discharge holes 421; otherwise, all discharge holes 421 will be closed by the sealing elements 440.

[0034] For cracks of different shapes, firstly, the cap 420 is removed from the discharge head 410. Then, the number of sealing parts 440 and / or the position of the sealing parts 440 are increased or decreased according to technical requirements. After that, the cap 420 is reinstalled back into the discharge head 410. Since the discharge holes 421 blocked by the sealing parts 440 cannot discharge normally, the discharge holes 421 not blocked by the sealing parts 440 can discharge normally because they are connected to the discharge channel 411. Therefore, through the above technical means, the distribution and number of effective discharge holes 421 can correspond to the grouting filling area, thereby ensuring that the grout is evenly distributed at each point during the grouting filling process, ensuring that the grout fully fills the crack, and thus meeting the grouting requirements of different cracks.

[0035] Furthermore, to prevent misalignment between the baffle 430 and the cover 420, one of the cover 420 and the baffle 430 is provided with a positioning groove 422, and the other is provided with a positioning post 432 that engages with the positioning groove 422. In this embodiment, the positioning groove 422 is provided on the cover 420, and the positioning post 432 is provided on the baffle 430. For ease of explanation, the positioning post 432 and the positioning groove 422 together constitute a positioning structure. When there is only one positioning structure, the cover 420 and the baffle 430 ideally have a unique positional relationship. However, if the number of the required sealing components 440 is small, there may be a lack of effective support between the cover 420 and the baffle 430.

[0036] Therefore, this embodiment sets the number of positioning structures to two or more. Taking four positioning structures as an example, the positions of the four positioning structures cannot be evenly distributed along the circumference. If the positions of the four positioning structures are evenly distributed along the circumference, then the positional relationship between the cover 420 and the baffle 430 will have four possibilities, which will become complicated in use, and the user will not be able to accurately position the baffle 430 and the cover 420 in a timely manner. Therefore, when there are multiple positioning structures, the layout of the positioning structures must ensure that the cover 420 and the baffle 430 have a unique positional relationship.

[0037] Since the cap 420 is threaded to the discharge head 410, as long as the size of the baffle 430 is set to be larger than the size of the discharge channel 411, when the cap 420 is tightened to the discharge head 410, the baffle 430 can abut against the end face of the discharge head 410 under the tightening of the cap 420, thereby limiting the position of the baffle 430 and preventing the position of the baffle 430 from being displaced due to the impact of the slurry.

[0038] like Figure 4 As shown, the mixing module 200 includes a material cylinder 210, a power source 220, and mixing blades 230. The top of the material cylinder 210 has an inlet 211, and the bottom of the material cylinder 210 has an outlet pipe 212. The grout inlet of the grouting pump 310 is connected to the outlet pipe 212 to achieve communication between the material cylinder 210 and the grouting pump 310. Since the grout needs to be mixed and stirred before it can be used to fill cracks, the inlet 211 of the material cylinder 210 is used to pour in the mixing material.

[0039] A cover 240 is detachably connected to the top of the material cylinder 210. Multiple bolts 241 are evenly distributed on the flange of the cover 240, and multiple threaded holes 213 for mating with the bolts 241 are provided on the side wall of the material cylinder 210. When installing the cover 240, first, the cover 240 is placed over the top of the material cylinder 210, then all the bolts 241 and threaded holes 213 are aligned, and finally all the bolts 241 are tightened to connect the cover 240 to the material cylinder 210. Furthermore, a power source 220, which can be an electric motor, is mounted on the outside of the cover 240 and extends into the material cylinder 210. The output shaft of the electric motor passes through the cover 240 and extends into the material cylinder 210. The output shaft of the electric motor is rigidly connected to the stirring blade 230 to achieve electrically controlled drive of the stirring blade 230.

[0040] To meet the requirements of dynamic balance, the output shaft of the motor needs to be located at the center of the cylinder cover 240. If the cylinder cover 240 has a circular structure, then the output shaft of the motor needs to be located at the center of the cylinder cover 240. If the cylinder cover 240 has a rectangular structure, then the output shaft of the motor needs to be located at the geometric center of the cylinder cover 240.

[0041] It is understandable that, since the shapes of the stirring blades 230 vary and different stirring materials may require stirring blades 230 with different structures, the specific structure of the stirring blades 230 is not limited here.

[0042] When material needs to be fed, the cylinder cover 240 is opened by loosening bolt 241, thereby exposing the feed inlet 211 of the material cylinder 210. The feed inlet 211 has a large size to allow the mixing material to be poured into the material cylinder 210. Since the power source 220 is installed on the cylinder cover 240, the stirring blade 230 is also installed on the cylinder cover 240. Therefore, the cylinder cover 240 must be reinstalled back into the material cylinder 210 before the power source 220 can drive the stirring blade 230 to mix the material in the material cylinder 210. During the mixing process in the material cylinder 210, because the cylinder cover 240 always covers the material cylinder 210, the slurry inside the material cylinder 210 will not splash and the inside and outside of the material cylinder 210 will be isolated from contact, ensuring production safety.

[0043] However, since hard deposits may exist at the bottom of the barrel 210, if the stirring blade 230 extends to the bottom of the barrel 210, it will accelerate blade wear and may even lead to blade breakage. Therefore, the stirring blade 230 generally does not extend to the bottom of the barrel 210, but this arrangement would exacerbate the sedimentation of the slurry at the bottom of the barrel 210. To address this, the stirring blade 230 is equipped with an agitator 250 extending to the bottom of the barrel 210. The agitator 250 includes a fixed frame 251 and multiple rake teeth 252. The fixed frame 251 is fixedly connected to the rotation shaft of the stirring blade 230, and the multiple rake teeth 252 are equidistantly distributed on the bottom surface of the fixed frame 251. When the stirring blade 230 rotates, the agitator 250 also rotates, and the multiple rake teeth 252 agitate the slurry at the bottom, thereby agitating the slurry at the bottom of the barrel 210 to prevent sedimentation.

[0044] Taking the material cylinder 210 as a cylindrical shape as an example, the length of the stirring rake 250 needs to be more than 80% of the inner diameter of the material cylinder 210 to achieve a better stirring effect without damaging the material cylinder 210. In some other embodiments, the material cylinder 210 may be configured as a structure that is wider at the top and narrower at the bottom. In this case, the inner diameter of the material cylinder 210 decreases with depth. For ease of explanation, the material cylinder 210 is provided with a stirring area for accommodating the stirring rake 250, and the length of the stirring rake 250 needs to be more than 80% of the inner diameter of the stirring area.

[0045] In some embodiments of this utility model, a switching valve 500 is installed on the discharge pipe 212 for easy control of material discharge. The switching valve 500 includes, but is not limited to, a solenoid valve, a ball valve, or a gate valve. In this embodiment, the switching valve 500 can be a solenoid valve, which is controlled by electricity. A switch assembly (not shown in the figures) is provided on the handcart 100. The switch assembly is electrically connected to mains power or a portable power source and is used to control the start and stop of various electrical appliances, such as the grouting pump 310, the motor, and the solenoid valve mentioned above. When the mixing module 200 is mixing the slurry, the switching valve 500 must be set to closed to prevent the slurry from flowing into the grouting pump 310 through the discharge pipe 212, thereby causing slurry leakage.

[0046] With the above structure, the grouting device has the following working process: First, the mixing material is placed into the material cylinder 210, the inlet 211 of the material cylinder 210 is covered with the cylinder cover 240, and the cylinder cover 240 is fixed with bolts 241. Then, the motor is started and made to run at high speed, and the mixing blade 230 is used to mix the slurry. After mixing, the motor is switched to low speed, and the stirring rake 250 is used to drive the slurry to flow continuously to prevent the slurry from settling.

[0047] Adjust the effective distribution of the discharge holes 421 according to the shape and width of the grouting area. First, remove the cap 420 and take out the baffle 430. Increase or decrease the number of sealing parts 440 and / or adjust the position of the sealing parts 440 according to the technical requirements so that the exposed installation holes 431 correspond to the shape and width of the grouting area. Then, reinstall the baffle 430 into the cap 420 and connect the cap 420 to the discharge head 410. At this time, some installation holes 431 are connected to the corresponding discharge holes 421. Open the switch valve 500 of the discharge pipe 212 and start the grouting pump 310. The grouting pump 310 discharges the grout through the installation holes 431 and the discharge holes 421 so that the grout fully fills each point of the crack.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
