DETAILED DESCRIPTION
[0027] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0028] Example:
[0029] like Figure 1-Figure 6 As shown, a specific embodiment of the building anti-crack reinforcement device of the present invention includes a base 11 and a mixing barrel 1 arranged on the base 11. The mixing barrel 1 is a cavity structure with an opening at one end, a piston disc 101 is arranged inside, a feed port 12 is arranged on the top, and a discharge port 501 is arranged at the bottom of the closed end.
[0030] A transverse stirring assembly is arranged in the stirring barrel 1 , a driving assembly for driving the transverse stirring assembly is arranged on the base 11 , a vertical stirring assembly is arranged on the transverse stirring assembly, and a discharge reinforcement assembly is connected to the discharge port 501 .
[0031] The horizontal stirring assembly includes an axial stirring shaft 6 fixedly arranged at the center of the piston disc 101, a plurality of axial stirring blades 7 are connected to the axial stirring shaft 6, at least one side wall stirring shaft 8 is rotatably connected to the piston disc 101, and side wall stirring blades 9 are respectively arranged at the positions corresponding to each axial stirring blade 7 on the periphery of the side wall stirring shaft 8, and an enlarged head is provided at the end of the axial stirring blade 7, and the size of the side wall stirring blade 9 is consistent with the size of the enlarged head; the function of the enlarged head is to ensure that the axial stirring blade 7 has a certain spacing while increasing the contact area with the side wall stirring blade 9 as much as possible. Its necessity lies in that, on the one hand, since the vertical stirring assembly is placed between the adjacent blades of the axial stirring blade 7, and the vertical stirring assembly moves horizontally with the stirring barrel 1, the axial stirring blade 7 needs to have a certain spacing for arranging the vertical stirring assembly and ensuring its range of movement; on the other hand, it is necessary to realize the inner wall cleaning function by contacting the end of the axial stirring blade 7 with the side wall stirring blade 9. In order to improve the inner wall cleaning effect, it is necessary to increase the width of the end of the axial stirring blade 7 and increase the contact area, thereby reducing the arrangement spacing of the axial stirring blade 7.
[0032] In order to balance the needs of the above two aspects, an enlarged head structure is introduced. On the one hand, when the side wall stirring blades 9 rotate, they contact the enlarged heads of the inner wall and the axial stirring blades 7 respectively. This process scrapes the inner wall adhesion from the inner wall and then throws it into the mixing barrel 1 to re-add to the mixing, thereby completing the cleaning of the inner wall during the mixing process and the recycling and mixing of the inner wall adhesion; on the other hand, considering that there are gaps between the side wall stirring blades 9, the hydraulic telescopic rod 10 controls the mixing barrel 1 to perform horizontal reciprocating motion, so that the side wall stirring blades 9 can slide back and forth in the horizontal direction relative to the mixing barrel 1, ensuring that the side wall stirring blades 9 can clean the materials adhered to different positions on the inner wall of the mixing barrel 1.
[0033] The main innovation of the present invention is that the horizontal stirring assembly, the vertical stirring assembly, the driving assembly and the power assembly cooperate to stir the stirring barrel, which effectively prevents the building crack repair agent from adhering to and solidifying on the inner wall of the stirring equipment, and reduces the waste of the repair agent raw materials.
[0034] Specifically, Figure 1 and Figure 3 As shown, the driving assembly is used to drive the piston disk 101 to rotate, and then drive the axial stirring shaft 6 to rotate, and at the same time drive the side wall stirring shaft 8 and the side wall stirring blade 9 to rotate around the central axis of the piston disk 101 to start stirring; one end of the side wall stirring blade 9 is in contact with the inner wall of the stirring barrel 1, and the other end is in contact with the enlarged head of the axial stirring blade 7, the side wall stirring blade 9 is an elastic material group, and the driving assembly includes a motor 201 fixedly connected to the base 11, the output end of the motor 201 is fixedly connected to the piston disk 101, a gear ring 202 is provided on the base 11, and both sides of the gear ring 202 are fixedly connected to the base 11 through a fixing frame 204, and a side wall stirring gear 203 is fixedly connected to the side wall stirring shaft 8, and the side wall stirring gear 203 is meshed with the gear ring 202.
[0035] More specifically, if Figure 1 , Figure 2 and Figure 4As shown, the vertical stirring assembly is located between adjacent axial stirring blades 7, and is used to lift and radially stir the material. The vertical stirring assembly includes a plurality of sealing boxes 303 fixedly connected to the inside of the stirring barrel 1, and the bottom end of each sealing box 303 is rotatably connected to a spiral stirring shaft 304, and a spiral stirring blade 305 is arranged on the spiral stirring shaft 304. The sealing box 303 is movably penetrated by a sliding sleeve 301, and the sliding sleeve 301 is sleeved on the outside of the axial stirring shaft 6. The sliding sleeve 301 is provided with a sliding assembly adapted to the axial stirring shaft 6, and the sliding sleeve 301 is provided with a meshing assembly adapted to the spiral stirring shaft 304. Among them, the sliding assembly includes a slider 307 fixedly connected to the inner wall of the sliding sleeve 301, and a slide groove 306 is provided on the axial stirring shaft 6 at a position corresponding to the slider 307. The meshing assembly includes a vertical bevel gear 3021 fixedly connected to the outside of the sliding sleeve 301, and a horizontal bevel gear 3022 is fixedly connected to the top of the spiral stirring shaft 304. The vertical bevel gear 3021 and the horizontal bevel gear 3022 are perpendicular to each other and meshed in the sealing box 303. The meshing assembly is used for transmission between the axial stirring shaft 6 and the spiral stirring shaft 304. When the axial stirring shaft 6 starts to operate, the vertical stirring assembly starts to operate at the same time, ensuring that the crack repairing agent is stirred evenly in different directions.
[0036] Furthermore, if Figure 1 and Figure 6 As shown, the discharge reinforcement assembly includes an output pump 503 fixedly connected to the base 11, the input end of the output pump 503 is connected to the discharge port 501 through a discharge hose 502, an injection head 505 is provided on the base 11, the output end of the output pump 503 is connected to the injection head 505 through a discharge hose 504, and a lifting assembly for adjusting the height of the injection head 505 is provided on the base 11.
[0037] The lifting assembly includes a lifting slider 506 fixedly connected to the bottom of the injection head 505, and two screw rods 507 pass through the lifting slider 506. The bottom end of the screw rod 507 is fixedly connected to the base 11. The outer sleeve of the screw rod 507 is provided with two nuts 508 matching the threads of the screw rod 507. The two adjacent nuts 508 are respectively in contact with the top and bottom of the lifting slider 506. The injection head 505 is adjusted to align with the crack position by turning the nuts 508.
[0038] For example Figure 1 and Figure 5 As shown, in some embodiments, the base 1 is provided with a power assembly, which includes a hydraulic telescopic rod 10 fixedly connected to the base 11, the hydraulic telescopic rod 10 is located at the bottom of the mixing barrel 1, and the telescopic end of the hydraulic telescopic rod 10 is fixedly connected to the mixing barrel 1.
[0039] Two trusses 401 are fixedly connected to the bottom of the mixing barrel 1, and a number of rollers 402 are fixedly connected to the bottom of the trusses 401. Two vertical brackets 405 are symmetrically arranged on both sides of the mixing barrel 1. The vertical brackets 405 are fixedly connected to the base 11, and the top of the vertical brackets 405 is fixedly connected to a cylindrical slide rail 404. A columnar slider 403 is slidably connected in the cylindrical slide rail 404. Both ends of the columnar slider 403 are fixedly connected to the mixing barrel 1 for controlling the horizontal movement direction of the mixing barrel 1 to ensure stability.
[0040] like Figure 1 As shown, in other embodiments, a plurality of universal wheels 13 are provided at the bottom of the base 11 to facilitate moving the mixing barrel 1 to a position where the crack needs to be filled.
[0041] The working principle and use process of the present invention:
[0042] When starting work, the entire mixing barrel 1 is moved to the building crack through the universal wheel 13 at the bottom of the base 11, and then the raw materials of each component of the building crack repair agent are put into the mixing barrel 1 from the feed port 12 in proportion, and the motor 201 is started to drive the piston plate 101 to start rotating. The piston plate 101 drives the axial stirring shaft 6 to rotate, and at the same time drives the side wall stirring shaft 8 to rotate around the central axis of the piston plate 101. Synchronously, the side wall stirring gear 203 fixed on the side wall stirring shaft 8 is meshed with the gear ring 202 during the process of rotating around the central axis of the rotating piston plate 101 The side wall stirring shaft 8 and the side wall stirring blades 9 thereon rotate and start the side wall cleaning work. Synchronously, the axial stirring shaft 6 drives the axial stirring blades 7 thereon to start axial stirring work, and on the other hand, the axial stirring shaft 6 drives the sliding sleeve 301 and the vertical bevel gear 3021 to start rotating through the slider 307. The vertical bevel gear 3021 drives the horizontal bevel gear 3022 to rotate through the meshing transmission, and then synchronously drives the spiral stirring shaft 304 and the spiral stirring blades 305 thereon to rotate and start spiral stirring work.
[0043] The side wall stirring blades 9 are made of elastic material. When rotating, the side wall stirring blades 9 contact the inner wall of the stirring barrel 1 and the enlarged head of the axial stirring blades 7. The specific working process is that the side wall stirring blades 9 scrape off the material adhering to the inner wall of the stirring barrel 1, and then the side wall stirring blades 9 contact the axial stirring blades 7. The side wall stirring blades 9 are provided with a plurality of annularly arranged deformation parts, which contact and deform with the axial stirring blades 7 alternately in turn. When the side wall stirring blades 9 slide over the end of the axial stirring blades 7, the side wall stirring blades 9 restore their deformation, and the scraped material adhering to the side wall stirring blades 9 is thrown into the stirring barrel 1 and re-added to the stirring, thereby completing the instant cleaning of the inner wall during the stirring process and the recovery and stirring of the inner wall adhesion.
[0044] Considering the gaps between the side wall stirring blades 9, while the above-mentioned axial stirring shaft 6, axial stirring blade 7, side wall stirring shaft 8 and side wall stirring blade 9 are in operation, the hydraulic telescopic rod 10 is started to control the mixing barrel 1 to perform horizontal reciprocating motion, so that the side wall stirring blade 9 can slide back and forth in the horizontal direction relative to the mixing barrel 1, ensuring that the side wall stirring blade 9 can clean the materials adhering to different positions on the inner wall of the mixing barrel 1. In particular, by controlling the difference between the overall length of the vertical stirring assembly and the spacing between adjacent blades of the axial stirring blade 7 to be smaller than the spacing between adjacent blades of the side wall stirring blade 9, it can be ensured that the entire side wall stirring blade 9 can be completely scratched with the mixing barrel 1 during the horizontal reciprocating motion of the mixing barrel 1. Cover the entire gap between the adjacent blades of the side wall stirring blade 9.
[0045] When the mixing barrel 1 is performing horizontal reciprocating motion, the outside of the mixing barrel 1: the vertical direction is kept stable by two sets of trusses 401 and rollers 402, and the horizontal direction is controlled by the welded cylindrical slider 403 sliding in the cylindrical slide rail 404 to maintain the stability of horizontal motion; inside the mixing barrel 1: the mixing barrel 1 and the piston disk 101 slide relative to each other, the sealing box 303 fixedly connected to the mixing barrel 1 drives the sliding sleeve 301 to slide relative to the axial mixing shaft 6, and the slider 307 slides in the slide groove 306.
[0046] Before starting unloading and reinforcement, the staff drives the lifting slider 506 to slide relative to the screw rod 507, so as to adjust the initial height of the injection head 505. After the height of the injection head 505 is adjusted, the staff drives the two adjacent nuts 508 to rotate so that the two adjacent nuts 508 clamp the lifting slider 506 to fix the injection head 505 relative to the base 11, and drives the base 11 and the injection head 505 to move to the preset position through the universal wheel 13, and then starts the output pump 503. The stirred crack repair agent is sucked into the output pump 503 through the discharge port 501 and the discharge hose 502, and then pumped into the crack from the injection head 505 through the discharge hose 504.
[0047] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
