Description

Technical Field

[0001] The invention relates to the technical field related to building construction, and in particular to a gap grouting device for building construction. Background Art

[0002] Grouting equipment is a professional construction machine that uses chemical grouting to plug leaks and reinforce structures in cracks, expansion joints, construction joints, and structural joints between various buildings and underground concrete. It can have a repair effect. Common grouting devices are used to fill gaps in the road surface. As concrete pavements exceed a certain number of years, cracks will appear in the road surface due to long-term use of the roadbed, causing the roadbed to decline. Therefore, grouting equipment is needed to grout and repair the cracks.

[0003] However, the existing gap grouting for construction generally adopts traditional high-pressure grouting machines for operation. Since there are many gaps in construction projects and they are discontinuous, the efficiency of filling and grouting the building gaps by this method is not high. The high-pressure grouting machine is inconvenient to move. At the same time, some grouting materials will generally remain on the inner wall of the traditional grouting barrel, which is easy to cause waste.

[0004] The authorization announcement number is: CN218292827U discloses a grouting device for construction, which stirs the raw materials through a stirring mechanism, and by starting the electric telescopic rod on the rear side of the lower plate, it will drive the connecting plate to move synchronously to the right, and then the connecting plate drives the blocking plate to move to the right, and the concrete slurry will fall into the interior of the push box through the through hole. When the concrete slurry inside the push box reaches the required standard for the current building gap construction, the electric telescopic rod is started to retract, so that the connecting plate drives the blocking plate to retract into the interior of the sliding groove, and then the through hole is closed, thereby realizing the quantitative delivery of concrete slurry to the interior of the push box. For the characteristics of "many and short" building gaps, it can effectively carry out rapid grouting of multiple gaps in the building, thereby improving the efficiency of grouting construction.

[0005] However, the existing grouting equipment is not convenient for removing dust from the gaps in the construction road surface, which easily leads to the cement slurry being mixed with impurities such as dust when repairing the gaps, affecting the pouring effect and resulting in poor repair quality.

[0006] The authorization announcement number is: CN217810439U, which discloses a road grouting and pouring device for construction. By starting the fan, the fan injects high-pressure airflow into the interior of the air outlet seat through the ventilation hose, and blows air around the gap that needs grouting through the air outlet pipe, it is convenient to remove dust from the gaps in the construction road surface, and avoid the cement slurry being mixed with dust and other impurities when repairing the gaps, which affects the pouring effect, thereby improving the repair quality of the road surface gaps. By starting the second motor, the second motor transports the cement slurry inside the grouting barrel through the auger, and then the delivery hose and the grouting head cooperate to reinforce and repair the road surface gaps that need to be reinforced and repaired.

[0007] However, when filling the gap, the existing grouting equipment controls the transmission component through the motor to control the grouting head to discharge slurry. However, when the motor stops rotating, it will continue to rotate due to inertia, and the grouting head cannot be controlled to stop grouting in time. As a result, the slurry discharge of the existing grouting equipment cannot be reasonably controlled according to the size of the crack, which will lead to a waste of grouting raw materials.

[0008] Therefore, a gap grouting device for building construction is proposed. Summary of the invention

[0009] The object of the present invention is to provide a crack grouting device for construction, which can control the amount of grouting according to the size of the crack, so as to solve the problems raised in the above-mentioned background technology.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gap grouting device for construction, comprising a slurry storage barrel, a handle is fixed to the outer wall of the slurry storage barrel, a liquid outlet barrel is fixedly installed at the bottom of the slurry storage barrel, a switch device is arranged inside the liquid outlet barrel, and the switch device comprises a limit column, the limit column is a truncated cone structure, the upper end of the limit column is threadedly connected to a support cover, the bottom end of the limit column is rotatably installed with a connecting rod, the inner wall of the slurry storage barrel is installed with a motor, and the power output shaft of the motor is rotatably installed with a support plate; a limit spring is fixedly installed on the upper surface of the support plate, and one end of the limit spring away from the support plate is fixedly connected to the inner wall of the support cover, and the outer wall of the power output shaft of the motor is fixed with a stirring blade, and one side of the stirring blade is in contact with the outer wall of the limit column.

A threaded groove is provided on the outer side wall of the bottom end of the connecting rod, and a group of symmetrical scrapers are fixedly installed on the outer side wall of the connecting rod, and the scrapers are in contact with the inner wall of the liquid discharge barrel on the side away from the connecting rod.

[0012] Preferably, a feeding device for feeding the slurry is provided at the bottom of the liquid discharge cylinder, and the feeding device includes a group of chute plates, which are symmetrically mounted on the outer wall of the liquid discharge cylinder, and sliders are slidably mounted inside the two chute plates. The slider is L-shaped, and a discharge plate is fixedly mounted on the end of the slider away from the chute plate. The interior of the discharge plate is sloped, and a plurality of guide plates arranged equidistantly are fixedly mounted on the inner wall of the discharge plate. A snap-fit ​​plate is fixedly mounted on the outer wall of the slider, and the snap-fit ​​plate is U-shaped, and an extrusion bolt is threadedly connected to the outer wall of the snap-fit ​​plate. A roller is rotatably mounted on one end of the discharge plate. A cleaning plate is fixedly mounted on the bottom of the end of the discharge plate away from the roller, and the height of the cleaning plate is equal to that of the roller.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The stirring blade is driven by the motor to rotate, so that the grouting raw materials can be mixed evenly, and then the bottom end of the connecting rod is squeezed by manpower, so that the slurry inside the slurry storage tube can enter the gap between the limit column and the liquid discharge tube into the gap of the building construction. Continuously pressing the connecting rod will continuously release the slurry. When the pressing of the connecting rod is stopped, the connecting rod will drive the limit column to return to the outlet of the slurry storage tube under the action of the limit spring, so that the slurry release can be stopped; so that the slurry discharge amount of the grouting equipment can be manually controlled according to the size of the crack, which improves the grouting effect of the crack and does not cause waste of resources;

[0015] 2. The stirring blade is driven by the motor to rotate, so that the stirring blade can scrape the slurry around the limit column to prevent a large amount of slurry from being distributed around the limit column and causing resistance to the lifting and lowering of the limit column, thereby making the lifting and lowering of the limit column more labor-saving.

[0018] 5. The guide plate can disperse the slurry from the liquid discharge cylinder into the cracks to avoid the slurry accumulating in one place, which makes it convenient for the later slurry leveling process;

The road surface around the crack can be scraped by the cleaning plate to remove debris on the surface of the crack, which brings convenience to the grouting. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] 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.

[0033] See also Figures 1 to 9 , the present invention provides a technical solution:

[0034] A gap grouting device for construction, comprising a grout storage barrel 1, a handle 2 is fixed to the outer wall of the grout storage barrel 1, a liquid outlet barrel 4 is fixedly installed at the bottom of the grout storage barrel 1, a switch device 6 is arranged inside the liquid outlet barrel 4, and the switch device 6 comprises a limit column 61, the limit column 61 is a truncated cone structure, the upper end of the limit column 61 is threadedly connected with a support cover 63, the bottom end of the limit column 61 is rotatably installed with a connecting rod 64, the inner wall of the grout storage barrel 1 is installed with a motor 8, and the power output shaft of the motor 8 is rotatably installed with a support plate 68;

[0035] Specifically, Figure 1 , Figure 2 and Figure 6 As shown, a limit spring 67 is fixedly installed on the upper surface of the support plate 68, and one end of the limit spring 67 away from the support plate 68 is fixedly connected to the inner wall of the support cover 63. A stirring blade 10 is fixed to the outer wall of the power output shaft of the motor 8, and one side of the stirring blade 10 is in contact with the outer wall of the limit column 61.

[0036] By adopting the above technical solution, according to the "Study on Parameter Determination and Diffusion Path of Grouting Treatment for Asphalt Pavement Cracks" in "Baidu Encyclopedia":

[0037] Grouting technology is a common method for treating cracks in asphalt pavements. In order to reasonably determine the process parameters for grouting treatment of cracks in asphalt pavements, the grouting diffusion paths of three common working conditions, namely, cracks only, cracks + poor interlayer bonding, and cracks + loose interlayers, were studied. The key parameters such as grouting hole depth and grouting pressure were simulated and calculated. The research results show that:

[0038] When the grouting hole is located at the bottom of the upper base, the slurry can better fill the base; when the grouting pressure is 0.2, 0.3, 0.4, and 0.5 MPa, the grouting diffusion radius gradually increases. When the grouting pressure is greater than 0.6 MPa, it will cause the road surface to bulge and destroy the continuity between the pavement structure layers; combined with actual engineering experience, the construction parameters were optimized. This research result can provide theoretical and technical reference for the promotion of grouting technology for treating asphalt pavement cracks.

[0039] It can be seen that when grouting pavement cracks, the amount of slurry is particularly important; in order to be able to adjust the slurry output of the grouting device according to the size of the cracks; the handle 2 is convenient to hold, so that the entire grouting equipment can be picked up; the support cover 63 can cover the limit column 61; the motor 8 provides a power source for the rotation of the stirring blade 10; the elastic force provided by the limit spring 67 can keep the support cover 63 in the tendency to reset; the limit column 61 has a hollow shell inside, and the limit column 61 is a truncated cone structure, so that the upper end size of the limit column 61 is larger than the lower end size, so when the upper end of the limit column 61 is close to the slurry storage When the inner walls of the cylinder 1 fit together, the slurry cannot fall from the gap between the slurry storage cylinder 1 and the limiting column 61; and when the limiting column 61 rises, the gap between the bottom end of the limiting column 61 and the slurry storage cylinder 1 will become larger, so that the slurry can fall along the gap between the limiting column 61 and the slurry storage cylinder 1; a first bearing is fixed at the connection between the power output shaft of the motor 8 and the support plate 68, and the inner steel ring of the first bearing is fixedly connected to the outer wall of the power output shaft of the motor 8, and the outer steel ring of the first bearing can be fixedly connected to the outer wall of the support plate 68, so that when the motor 8 rotates, the support plate 68 will not rotate with the motor 8.

[0040] A connecting shaft is fixed to the top of the connecting rod 64, and a second bearing is fixedly installed on the outer side wall of the upper end of the connecting shaft. The outer ring wall of the second bearing is fixedly connected to the outer side wall of the bottom of the limiting column 61, and the outer ring wall of the second bearing is embedded in the bottom of the limiting column 61, thereby realizing the rotational connection between the limiting column 61 and the connecting rod 64; the stirring blade 10 is driven by the motor 8 to rotate, so that the grouting raw materials can be mixed evenly, and then the bottom end of the connecting rod 64 is squeezed by manpower, so that the slurry inside the slurry storage tube 1 can enter the gap in the construction from the gap between the limiting column 61 and the liquid outlet tube 4, and the connecting rod 64 is continuously pressed to continuously release the slurry. When the connecting rod 64 is stopped, the connecting rod 64 will drive the limiting column 61 to return to the outlet of the slurry storage tube 1 under the action of the limiting spring 67, so that the slurry release is stopped; thereby, the slurry discharge amount of the grouting equipment can be manually controlled according to the size of the crack, thereby improving the grouting effect of the crack and not causing waste of resources.

[0041] Specifically, Figure 1 , Figure 2 and Figure 6 As shown, the top of the slurry storage barrel 1 is threadedly connected with a rotating cover 3, the inner wall of the slurry storage barrel 1 is fixedly mounted with a support plate 7, and the motor 8 is fixedly mounted on the upper surface of the support plate 7. The support plate 68 is placed inside the limit column 61, and a rubber ring 62 is fixed at the center of the support cover 63, and the rubber ring 62 is sleeved on the outside of the power output shaft of the motor 8.

[0042] By adopting the above technical scheme, in order to save effort when the limit column 61 is lifted up; the threaded connection between the slurry storage barrel 1 and the rotating cover 3 can prevent the slurry from flowing out from the inside of the slurry storage barrel 1 when the grouting device is moving; in addition, when the motor 8 drives the stirring blade 10 to rotate, the raw materials inside the slurry storage barrel 1 can be stirred; there is no need to mix the slurry raw materials required by the grouting equipment separately, saving manpower; at the same time, the stirring blade 10 is driven by the motor 8 to rotate, so that the stirring blade 10 can scrape the slurry around the limit column 61 to prevent a large amount of slurry from being distributed around the limit column 61, and to avoid the slurry around the limit column 61 bringing resistance to the lifting and lowering of the limit column 61, thereby making the lifting and lowering of the limit column 61 save effort, and the support cover 63 is used to seal the limit spring 67 inside the limit column 61, so as to prevent the slurry from contacting the limit spring 67 and affecting the use of the limit spring 67, thereby protecting the limit spring 67.

[0043] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a threaded groove 65 is formed on the outer side wall of the bottom end of the connecting rod 64 , and a group of symmetrical scrapers 66 are fixedly mounted on the outer side wall of the connecting rod 64 , and the side of the scrapers 66 away from the connecting rod 64 contacts the inner wall of the liquid discharge cylinder 4 .

[0044] By adopting the above technical scheme, in order to facilitate the cleaning of the slurry on the inner wall of the liquid discharge tube 4; the threaded groove 65 can increase the roughness of the connecting rod 64 and the hand, thereby increasing the friction between the connecting rod 64 and the hand, so that human power can prevent slipping when rotating the connecting rod 64; the scraper 66 can scrape the slurry on the inner wall of the liquid discharge tube 4; by rotating the connecting rod 64, the connecting rod 64 drives the scraper 66 to scrape the slurry on the inner wall of the liquid discharge tube 4, thereby facilitating the later cleaning of the slurry on the inner wall of the liquid discharge tube 4, and also enabling the slurry on the inner wall of the liquid discharge tube 4 to be cleaned in time when the inside of the liquid discharge tube 4 is blocked.

[0045] Specifically, Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, a feeding device 9 for feeding mud is provided at the bottom of the liquid discharge cylinder 4, and the feeding device 9 includes a set of chute plates 91, and the chute plates 91 are symmetrically mounted on the outer wall of the liquid discharge cylinder 4, and sliders 97 are slidably mounted inside the two chute plates 91. The slider 97 is L-shaped, and a discharge plate 92 is fixedly mounted on one end of the slider 97 away from the chute plate 91.

[0046] By adopting the above technical scheme, in order to prevent the slurry coming out of the liquid discharge tube 4 from spilling everywhere; the slide groove plate 91 provides a sliding space for the slider 97; the interior of the discharge plate 92 is sloped, and the discharge plate 92 can collect the slurry at the bottom of the liquid discharge tube 4, and then make the slurry slide along the slope inside the discharge plate 92, so that the discharge plate 92 has a guiding function; the slurry flows along the discharge plate 92 to the specified crack, thereby realizing the positioning of the flow direction of the slurry.

[0047] Specifically, Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, a plurality of guide plates 98 arranged at equal distances are fixedly mounted on the inner wall of the discharge plate 92. A buckle plate 95 is fixedly mounted on the outer wall of the slider 97. The buckle plate 95 is in a U shape, and a squeeze bolt 96 is threadedly connected to the outer wall of the buckle plate 95. A roller 94 is rotatably mounted on one end of the discharge plate 92. A cleaning plate 93 is fixedly mounted on the bottom of one end of the discharge plate 92 away from the roller 94, and the height of the cleaning plate 93 is equal to that of the roller 94.

[0048] By adopting the above technical scheme, in order to make the slurry flow in a fixed direction; the guide plate 98 can disperse the slurry entering the inner wall of the discharge plate 92; avoid the slurry from accumulating in one place, which brings convenience to the later slurry flattening treatment, and at the same time, the guide plate 98 can disperse a large amount of slurry into multiple thin streams sliding down from the surface of the discharge plate 92, so that the thin streams are easy to control when filling the building gaps, and prevent excessive slurry from entering the gaps, causing waste of resources; a rotating shaft is fixedly installed at one end of the discharge plate 92, and the roller 94 is rotatably installed on the outer wall of the rotating shaft, thereby facilitating the rotation of the roller 94; by rotating the squeezing bolt 96, the outer wall of the liquid discharge tube 4 is squeezed, so that the liquid discharge tube 4 and the discharge plate 92 are firmly fixed, and the discharge plate 92 is moved, so that the discharge plate 92 drives the roller 94, so that the roller 94 can flatten the mud on the surface of the slurry, ensure the beauty of the grouting effect, and scrape the road surface around the crack by the cleaning plate 93, so that the debris on the surface of the crack can be removed, which brings convenience to the grouting.

[0049] Working principle: When grouting is required for road cracks, first put the raw materials needed by the grouting equipment into the grout storage barrel 1, and drive the stirring blade 10 to rotate through the motor 8 to mix the grouting raw materials evenly, and then squeeze the bottom end of the connecting rod 64 by manpower, so that the slurry inside the slurry storage barrel 1 can enter the gap between the limit column 61 and the liquid outlet barrel 4 into the gap of the building construction. Continuously press the connecting rod 64 to continuously release the slurry. Stop pressing the connecting rod 64, and the connecting rod 64 will drive the limit column 61 to return to the outlet of the slurry storage barrel 1 under the action of the limit spring 67, so as to stop releasing the slurry; thereby, the slurry discharge amount of the grouting equipment can be manually controlled according to the size of the cracks, thereby improving the grouting effect of the cracks and not causing waste of resources.

[0050] In addition, the motor 8 drives the stirring blade 10 to rotate, so that the stirring blade 10 can scrape the slurry around the limit column 61, preventing a large amount of slurry from being distributed around the limit column 61, and preventing the slurry around the limit column 61 from causing resistance to the lifting and lowering of the limit column 61, thereby making the lifting and lowering of the limit column 61 more labor-saving. The support cover 63 is used to seal the limit spring 67 inside the limit column 61, thereby preventing the slurry from contacting the limit spring 67 and affecting the use of the limit spring 67, thereby protecting the limit spring 67.

[0051] By rotating the connecting rod 64, the connecting rod 64 drives the scraper 66 to scrape the slurry on the inner wall of the liquid outlet tube 4, thereby facilitating the cleaning of the slurry on the inner wall of the liquid outlet tube 4 at a later time, and also enabling the slurry on the inner wall of the liquid outlet tube 4 to be cleaned in time when the inside of the liquid outlet tube 4 is blocked.

[0052] The guide plate 98 can disperse the slurry that enters the inner wall of the discharge plate 92, and avoid the slurry from accumulating in one place, which brings convenience to the later slurry flattening process. When the slurry needs to be released, first loosen the extrusion bolt 96 and press the slurry storage barrel 1 downward. The slurry storage barrel 1 will drive the connecting rod 64 and the inner wall of the discharge plate 92 to be squeezed, and the slider 97 will slide inside the slide plate 91. The slurry will fall from the liquid discharge barrel 4 to the inside of the discharge plate 92. At this time, the guide plate 98 can disperse a large amount of slurry into multiple thin streams that slide down from the surface of the discharge plate 92, so that the thin streams are easy to control when filling the building gaps, preventing excessive slurry from entering the gaps and causing waste of resources.

[0053] The outer wall of the liquid discharge tube 4 is squeezed by rotating the squeezing bolt 96, so that the liquid discharge tube 4 and the discharge plate 92 are firmly fixed, and the discharge plate 92 is moved, so that the discharge plate 92 drives the roller 94, so that the roller 94 can flatten the mud on the surface of the slurry to ensure the beauty of the grouting effect, and the road surface around the crack is scraped by the cleaning plate 93, so that the debris on the surface of the crack can be removed, which brings convenience to the grouting.
