Description

Technical Field

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. During the construction of water conservancy projects, a certain proportion of cement slurry needs to be poured into the foundation gaps, cracks or cracks of the building itself with appropriate pressure for filling, bonding, anti-seepage or reinforcement. This work process is called grouting.

[0003] At present, during the grouting process of the existing grouting equipment, the slurry will continue to adhere to the inner wall of the grouting equipment. After the grouting is completed, if the inner wall is not cleaned in time, the slurry will continue to adhere, which will not only cause waste of slurry and increase grouting costs, but also easily cause slurry fermentation, affecting the uniformity of the next slurry component. When the slurry is stirred, the operating energy consumption of the grouting equipment is increased, the grouting cost is increased, and bubbles are likely to appear inside the slurry when the slurry is stirred. If the slurry mixed with bubbles is poured into the cracks of underground concrete projects, cavities will appear inside the slurry after it solidifies, resulting in low stability of the construction structure.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] For an embodiment of the present invention, please refer to Figures 1 to 11 , comprising a base 1, four rotating shafts are connected to the four corners of the side of the base 1 through bearings, and walking wheels 102 are arranged at the ends of the rotating shafts, a stirring mechanism 3 is arranged in the middle of the top of the base 1, a pump slurry mechanism 4 is arranged at one end of the top of the base 1, and a push rod 101 is arranged at the other end of the top of the base 1, and a switch panel 2 is detachably connected to the middle of the top of the push rod 101. The bottom of the stirring mechanism 3 is fixedly connected to the top of the base 1 through a support frame 302, a driving mechanism 6 is arranged on one side of the top of the stirring mechanism 3, and a plurality of air pumps 5 are arranged on the top of the stirring mechanism 3 in a circular array; like Figure 2 and Figure 3 As shown, the stirring mechanism 3 includes a stirring tank 301 supported on the top of a support frame 302, and the driving mechanism 6 includes a stirring motor 600 arranged on the top of the stirring tank 301, and the output shaft of the stirring motor 600 is vertically inserted into the top wall of the stirring tank 301 downward, as shown in FIG. Figure 5 or Figure 6 As shown, the output shaft end of the stirring motor 600 is keyed to an intermediate gear 607, one side of the intermediate gear 607 is meshedly connected to a sun gear ring 601, and the outside of the sun gear ring 601 is dynamically connected to a gear ring 603 through a planetary gear 602, as shown in FIG. Figure 7 and Figure 8As shown, a plurality of rotating plates 701 are distributed in a circular array at the bottom of the gear ring 603, and a plurality of stirring blades 702 are distributed vertically and evenly at intervals on the rotating plates 701. The inner wall of the bottom of the sun gear ring 601 is connected to an intermediate shaft 604 through a tripod rod 605, and an auger 609 is provided on the intermediate shaft 604; In specific use, after the slurry is injected into the stirring tank 301, in order to prevent the slurry from solidifying, the slurry is continuously stirred, the driving mechanism 6 is started through the switch panel 2, and the power provided by the stirring motor 600 is used to drive the intermediate gear 607 to rotate, thereby rotating the sun gear ring 601, and the planetary gear 602 is driven by the sun gear ring 601 to rotate, driving the ring gear 603 and the sun gear ring 601 to rotate in the opposite direction. Therefore, the tripod 605 can drive the intermediate shaft 604 to rotate under the drive of the sun gear ring 601, so that the intermediate shaft 604 The auger 609 on the upper part rotates to continuously transport the slurry upward. At the same time, the rotating plate 701 can also rotate under the drive of the ring gear 603, so that the stirring blade 702 and the expanding tube 703 rotate in the other direction, thereby forming a situation in which the slurry outside the expanding tube 703 rotates in one direction and flows downward, and the slurry inside the expanding tube 703 rotates in the opposite direction and moves upward, thereby accelerating the stirring of the slurry. In the process of the slurry moving upward, it will also overflow from the gap between the expanding tubes 703, thereby further accelerating the mixing and stirring of the slurry.

[0023] like Figure 5 As shown, the bottom of the intermediate gear 607 is connected to the input shaft of the air pump 5 through the meshing speed increasing gear set 608, as shown in FIG. Figure 3 As shown, an exhaust pipe 502 and an air return pipe 503 are provided on one side of the top of the air pump 5. Figure 6 and Figure 7 As shown, the return air pipe 503 penetrates the top wall of the stirring tank 301 and is inserted into the interior of the stirring tank 301, and the end of the return air pipe 503 is connected to the injection pipe 504, as shown in FIG. Figure 8 As shown, the air inlet of the air pump 5 is connected to the air suction hood 506 located inside the stirring tank 301.

[0024] When used specifically, Figure 4 and Figure 5 As shown, when one of the intermediate gears 607 rotates, all the intermediate gears 607 can rotate simultaneously through the meshing of the sun gear ring 601. After the speed is increased by the speed-increasing gear set 608, the input shaft of the air pump 5 rotates to drive the air pump 5 to start working. When stirring the internal slurry, the air pump 5 works normally to suck the air inside the mixing tank 301 from the air intake hood 506. Under the control of the switch panel 2, the air is discharged from the exhaust pipe 502 or the return air pipe 503.

[0025] like Figure 7As shown, the top wall of the stirring tank 301 is provided with connecting columns 610 distributed in a circular array, the outside of the connecting columns 610 is connected to the planetary gear 602 through a bearing, the bottoms of all the connecting columns 610 are connected to the same fixed ring 606, the outer wall of the fixed ring 606 is connected to the gear ring 603 through a bearing, the inner wall of the fixed ring 606 is connected to the sun gear ring 601 through a bearing, the inner wall of the sun gear ring 601 is connected to the feed port set at the top of the stirring tank 301 through a bearing, and a sealing cover 303 is set on the top of the feed port.

[0026] During specific use, the sun gear ring 601 is connected to the feed port of the mixing tank 301 through the internal bearing when rotating, and is connected to the fixed ring 606 through the bearing on the outside, so that the sun gear ring 601 can rotate normally, and the fixed ring 606 is connected to the top wall of the mixing tank 301 through the connecting column 610 to ensure the stability of the fixed ring 606. At the same time, the planetary gear 602 is connected to the connecting column 610 through the bearing to transmit the power of the sun gear ring 601 to the ring gear 603. The inner wall of the ring gear 603 is connected to the outer wall of the fixed ring 606 through the bearing to ensure that the ring gear 603 can rotate smoothly driven by the planetary gear 602.

[0027] like Figure 8 As shown, the air suction hood 506 and the air jet pipe 504 are fixedly connected to the bottom of the fixed ring 606. The number of the air suction hood 506 and the air jet pipe 504 is the same as that of the air pump 5, and they are all distributed in a circular array, as shown in FIG. Figure 7 As shown, a plurality of nozzles 505 are arranged at equal intervals at the bottom of the gas injection pipe 504, and the inclination angles of the plurality of nozzles 505 gradually increase from the middle to both ends, so that the gas ejected from the plurality of nozzles 505 diffuses in a fan shape.

[0028] like Figure 3 As shown, an electric control valve 501 is provided on the top of the air pump 5. The electric control valve 501 is a three-position five-way valve. The electric control valve 501 is electrically connected to the switch panel 2. The end of the exhaust pipe 502 is connected to the external atmosphere. The electric control valve 501 is used to switch the connection between the air outlet of the air pump 5 and the exhaust pipe 502 and the return air pipe 503, as well as the direct connection between the air inlet of the air pump 5 and the exhaust pipe 502.

[0029] In specific use, when it is necessary to add slurry, the switch panel 2 is used to control the electric control valve 501 so that the air inlet of the air pump 5 is directly connected to the exhaust pipe 502, so that the air pressure inside and outside the stirring tank 301 is the same, which is convenient for opening the sealing cover 303 to add slurry into the stirring tank 301. When the internal slurry is stirred, the inside of the stirring tank 301 is sealed by the sealing cover 303, and the slurry is stirred under the drive of the stirring motor 600. The air pump 5 also works under the drive of the stirring motor 600. At this time, the switch panel 2 is used to control the electric control valve 501 so that the air outlet of the air pump 5 is directly connected to the exhaust pipe 502, and the stirring tank 301 is stirred. 1, the air inside is gradually extracted, and the air pressure outside the slurry is reduced to prevent bubbles from appearing inside the slurry. When it is necessary to clean the inside of the stirring tank 301, the switch panel 2 is used to control the electric control valve 501 to connect the air outlet of the air pump 5 with the return air pipe 503. Since there is no slurry inside the stirring tank 301, the load of the stirring motor 600 is reduced. The speed of the stirring motor 600 is increased by the switch panel 2, and the pumped air enters the stirring tank 301 from the return air pipe 503, and is sprayed from the nozzle 505 by high-speed airflow to further clean the slurry on the surface of the stirring blade 702, so as to avoid the slurry from adhering to the inside of the device.

[0030] like Figure 8 and Fig.11 As shown, the bottom of the intermediate shaft 604 is connected to a bearing ring 611 through a bearing, a cross rod 612 is arranged outside the bearing ring 611 , and the end of the cross rod 612 is fixedly connected to the inner wall of the discharge port opened at the bottom of the mixing tank 301 .

[0031] During specific use, the top of the intermediate shaft 604 is connected to the sun gear ring 601 through the tripod rod 605, which can enable the sun gear ring 601 to drive the intermediate shaft 604 to rotate when it rotates. At the same time, the bottom of the intermediate shaft 604 is connected to the bearing ring 611 through a bearing, and is connected to the discharge port of the mixing tank 301 through a cross rod 612, which will not affect the inlet and outlet of the slurry and can ensure the stability of the rotation of the auger 609.

[0032] like Fig. 9 and Fig.10 As shown, the outer part of the auger 609 is covered with a plurality of flared tubes 703, which are arranged at equal intervals up and down, with a trumpet opening at the top and a cylinder at the bottom, and the inner ends of the stirring blades 702 at the same height are connected to the outer wall of the same flared tube 703, and the plurality of flared tubes 703 are connected into one by a vertical connecting rod 705 arranged vertically.

[0033] like Fig.10As shown, the bottom end of the vertical connecting rod 705 extends out from the bottom of the bottom flared tube 703, and a conical vortex plate 706 is provided on the bottom side of the vertical connecting rod 705, and the bottom wall of the conical vortex plate 706 is matched with the inner bottom wall of the mixing tank 301. The outer wall of the rotating plate 701 is provided with a plurality of spiral scrapers 704, and the outer wall of the spiral scraper 704 is matched with the inner wall of the mixing tank 301.

[0034] During specific use, the rotation of the ring gear 603 drives the rotating plate 701 to rotate. Since the spiral scraper 704 arranged outside the rotating plate 701 can clean the inner wall of the stirring tank 301 when rotating, the slurry can be prevented from adhering to the inner wall of the stirring tank 301 when stirring the slurry. In the stage of separately cleaning the inside of the stirring tank 301, the spiral scraper 704 and the conical vortex plate 706 can be used to clean the inner wall and the bottom wall of the stirring tank 301 at the same time.

[0035] like Figure 2 and Figure 4 As shown, the slurry pumping mechanism 4 includes a pump box 401 , and a slurry pumping motor 402 is connected to one side of the outer wall of the pump box 401 by bolts, and the output shaft of the slurry pumping motor 402 is dynamically connected to the mud pump input shaft inside the pump box 401 .

[0036] A slurry inlet pipe 404 is provided on one side wall of the pump box 401 close to the stirring mechanism 3, and the connecting end of the slurry inlet pipe 404 is connected to the discharge port at the bottom of the stirring tank 301. A slurry outlet pipe 403 is provided on the top of the pump box 401, and the slurry outlet pipe 403 and the slurry inlet pipe 404 are both connected to the mud pump inside the pump box 401.

[0037] During specific use, when grouting construction is carried out, the pump motor 402 is started through the switch panel 2 to drive the mud pump inside the pump motor 402 to work, and the slurry being stirred inside the mixing tank 301 is extracted through the slurry inlet pipe 404, and after pressurization, it is discharged from the slurry outlet pipe 403 and transported to the location where grouting is required through the pipeline.

[0038] The specific steps and principles of using this device are as follows: First, the switch panel 2 is used to control the electric control valve 501 to directly connect the air inlet of the air pump 5 with the exhaust pipe 502, so that the air pressure inside and outside the stirring tank 301 is the same, which is convenient for opening the sealing cover 303, and then the slurry to be used is added to the stirring tank 301. After the slurry is added, the sealing cover 303 is used to seal the stirring tank 301 again, and the switch panel 2 is used to control the electric control valve 501 to directly connect the air outlet of the air pump 5 with the exhaust pipe 502, and the stirring motor 600 is started through the switch panel 2. Figure 6 As shown, when the stirring motor 600 rotates, the intermediate gear 607 key-connected on the output shaft of the stirring motor 600 will directly rotate, thereby driving the sun gear ring 601 to rotate; like Figure 4 and Figure 5 As shown, after the sun gear ring 601 rotates, the other intermediate gear 607 will rotate synchronously. On the one hand, after the speed is increased by the speed-increasing gear set 608, the air pump 5 starts to work to extract the air inside the mixing tank 301, and forms a negative pressure inside the mixing tank 301 to prevent bubbles from existing inside the slurry, thereby improving the quality of the slurry. On the other hand, the sun gear ring 601 drives the gear ring 603 to rotate through the planetary gear 602. Since the position of the planetary gear 602 has been fixed, the sun gear ring 601 and the gear ring 603 rotate in opposite directions. The sun gear ring 601 drives the tripod rod 605 to rotate, so that the intermediate shaft 604 drives the auger 609 to rotate. At the same time, Fig. 9 As shown, since the bottom of the gear ring 603 is connected with a rotating plate 701, the rotating plate 701 can drive the stirring blade 702 and the flaring tube 703 to rotate together. Therefore, under the drive of the sun gear ring 601, the tripod 605 can drive the intermediate shaft 604 to rotate, so that the auger 609 on the intermediate shaft 604 rotates to continuously transport the slurry upward. At the same time, the rotating plate 701 can also rotate under the drive of the gear ring 603, so that the stirring blade 702 and the flaring tube 703 rotate in the other direction, so that the slurry outside the flaring tube 703 rotates in one direction and flows downward, and the slurry inside the flaring tube 703 rotates in the opposite direction and moves upward, thereby accelerating the stirring of the slurry. In the process of the slurry moving upward, it will also overflow from the gap between the flaring tubes 703, further accelerating the mixing and stirring of the slurry. At the same time, the rotation of the gear ring 603 drives the rotating plate 701 to rotate. Since the spiral scraper 704 arranged outside the rotating plate 701 can clean the inner wall of the stirring tank 301 when rotating, the slurry can be prevented from adhering to the inner wall of the stirring tank 301 when stirring the slurry, thereby achieving the purpose of cleaning the device; After the device moves to the position where grouting is required via the walking wheel 102, the switch panel 2 is used to start the slurry pump motor 402 to drive the mud pump inside the slurry pump motor 402 to work, and the slurry being stirred inside the mixing tank 301 is extracted through the slurry inlet pipe 404, and after pressurization, it is discharged from the slurry outlet pipe 403 and transported to the position where grouting is required through the pipeline; After all the slurry in the stirring tank 301 is discharged, the slurry can be added again for continued use. When it is not used for a long time, the switch panel 2 is used to control the electric control valve 501 to directly connect the air inlet of the air pump 5 with the exhaust pipe 502, so that the air pressure inside and outside the stirring tank 301 is the same, which is convenient for opening the sealing cover 303, and then spraying water into the stirring tank 301. At the same time, the switch panel 2 is used to control the electric control valve 501 to connect the air outlet of the air pump 5 with the return air pipe 503. Since there is no slurry in the stirring tank 301, the stirring motor 60 0 is reduced, and the speed of the stirring motor 600 is increased by the switch panel 2, so that the stirring blade 702 can rotate faster, so that the stirring blade 702 can rotate quickly to shake off the slurry on the surface. Moreover, after the electric control valve 501 is adjusted, the pumped air can enter the stirring tank 301 from the return air pipe 503, and be ejected from the nozzle 505 by high-speed airflow, and the air is ejected downward in a fan shape, and the high-speed airflow is used to further clean the slurry on the surface of the stirring blade 702, so as to avoid the slurry adhering to the inside of the device.
