Description

Technical Field

[0001] The utility model relates to the technical field of mass concrete curing, in particular to a mass concrete curing device. Background Art

[0002] During the curing period of large-volume concrete structures, the heat on the concrete surface dissipates quickly, while the internal heat is not easy to dissipate, resulting in a large temperature difference between the interior and the surface. When the temperature difference exceeds a certain critical value, the concrete's autogenous tensile strength is insufficient to resist the tensile stress caused by uneven shrinkage of the concrete, and temperature cracks will occur on the concrete surface, affecting the durability of the concrete structure.

[0003] Therefore, during the curing of large-volume concrete, it is necessary to spray curing liquid on the surface of the large-volume concrete in time so that there will not be a large temperature difference between the inside and the surface of the large-volume concrete. When spraying the curing liquid on the surface of the large-volume concrete, the existing method is mostly to spray the curing liquid directly on the surface of the large-volume concrete. However, since there will be dust in the large-volume concrete, part of the sprayed curing liquid is easily absorbed by the dust, resulting in less water entering the surface of the large-volume concrete, thereby reducing the curing effect of the large-volume concrete.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The dust removal structure 12 includes a dust removal fixed tube 1201, which is fixed at an oblique position above the surface of the fixed tube 6. A dust removal slide tube 1202 is slidably arranged inside the dust removal fixed tube 1201. An upper sliding ring 1203 is fixed on the surface of the dust removal slide tube 1202. An upper spring 1204 is movably sleeved on the surface of the dust removal slide tube 1202. An air inlet hole 1205 is provided on the surface of the dust removal slide tube 1202. A dust removal pressure valve 1206 is installed inside the dust removal slide tube 1202. An air collecting hood 1207 is fixed on the dust removal pressure valve 1206. A pressurizing air valve 1208 is installed at one end of the outer side of the dust removal slide tube 1202. An air guide hose 1209 is fixed between the dust removal pressure valve 1206 and the pressurizing air valve 1208.

[0028] The maintenance structure 13 includes a water outlet fixed pipe 1301, which is fixed at an oblique position below the surface of the fixed tube 6. A water outlet slide pipe 1302 is slidably arranged inside the water outlet fixed pipe 1301, a lower sliding ring 1303 is fixed on the surface of the water outlet slide pipe 1302, a lower spring 1304 is movably sleeved on the surface of the water outlet slide pipe 1302, a water outlet pressure valve 1305 is installed inside the water outlet slide pipe 1302, a pressurized water valve 1306 is installed at one end of the outer side of the water outlet slide pipe 1302, a water inlet hose 1307 is fixed on the water outlet pressure valve 1305, a hollow sinking ball 1308 is fixed at one end of the outer side of the water inlet hose 1307, and a water outlet hose 1309 is fixed between the water outlet pressure valve 1305 and the pressurized water valve 1306.

[0029] Furthermore, the water storage tank 2, the bridge box 7 and the fixed barrel 6 are interconnected, an automatic filling structure is arranged inside the bridge box 7, and a liquid level monitor is arranged inside the fixed barrel 6 at the bottom end of the automatic filling structure. The principle of the automatic filling structure is a system that can automatically complete material filling, which is the prior art and will not be repeated here. The model of the liquid level monitor is a CYW11 universal liquid level gauge, so as to monitor the liquid level of the curing liquid inside the fixed barrel 6 and automatically fill it.

[0030] Furthermore, the outer diameter of the spiral piece 11 is smaller than the inner diameter of the fixed cylinder 6, the outer surface of the spiral piece 11 is an inclined surface, and the outer end of the spiral piece 11 is an isosceles trapezoidal shape. When the spiral piece 11 rotates, the inclined surface on the spiral piece 11 first contacts the spherical end of the dust removal slide pipe 1202. When the inclined surface on the spiral piece 11 is separated from the spherical end of the dust removal slide pipe 1202, the inclined surface on the spiral piece 11 contacts the spherical end of the water outlet slide pipe 1302 again, and the cycle is repeated. Therefore, during the rotation of the spiral piece 11, it can continuously and alternately separate from and then contact with the dust removal slide pipe 1202 and the water outlet slide pipe 1302, or first contact and then separate from them. Therefore, the dust removal slide pipe 1202 and the water outlet slide pipe 1302 at different positions can be continuously moved, so that the concrete surface can be continuously dusted first and then the curing liquid can be continuously sprayed.

[0031] Furthermore, the dust removal fixed pipe 1201 is fixed at an angle above the surface of the fixed cylinder 6 and extends to the interior of the fixed cylinder 6. One end of the upper spring 1204 is fixedly connected to the upper slip ring 1203, and the other end is fixedly connected to the dust removal fixed pipe 1201. When the dust removal sliding pipe 1202 moves, the upper slip ring 1203 can drive the upper spring 1204 to deform, so that the dust removal sliding pipe 1202 can move back and forth inside the dust removal fixed pipe 1201 through the deformation of the upper spring 1204.

[0032] Furthermore, the air inlet hole 1205 is located on the outside of the dust removal fixed tube 1201, and the air inlet hole 1205 is located above the liquid level of the curing liquid inside the fixed tube 6. The air inlet hole 1205 is located above the liquid level of the curing liquid inside the fixed tube 6, so that gas can be transported to the dust removal pressure valve 1206 through the air inlet hole 1205 and the air collecting hood 1207, and the gas is discharged from the pressurized air valve 1208 after passing through the air guide hose 1209.

[0033] Furthermore, the inner end of the dust removal slide tube 1202 is spherical, and the spherical end of the dust removal slide tube 1202 contacts the inclined surface on the spiral plate 11, so that when the inclined surface on the spiral plate 11 contacts the spherical end of the dust removal slide tube 1202, the spiral plate 11 can push the dust removal slide tube 1202 to move outward.

[0034] Furthermore, the water outlet fixed pipe 1301 is fixed at an angle below the surface of the fixed cylinder 6, and the water outlet fixed pipe 1301 extends to the interior of the fixed cylinder 6. One end of the lower spring 1304 is fixedly connected to the lower sliding ring 1303, and the other end is fixedly connected to the water outlet fixed pipe 1301. When the water outlet slide tube 1302 drives the lower sliding ring 1303 to move, the lower spring 1304 is deformed, so that the lower sliding ring 1303 can drive the water outlet slide tube 1302 to reset through the deformation of the lower spring 1304, so that the water outlet slide tube 1302 can move back and forth inside the water outlet fixed pipe 1301.

[0035] Furthermore, the water inlet hose 1307 extends to the outside of the water outlet slide pipe 1302, and the connection between the water inlet hose 1307 and the water outlet slide pipe 1302 is located on the outside of the water outlet fixed pipe 1301. A through hole is opened on the surface of the hollow sinking ball 1308, and the hollow sinking ball 1308 is located below the liquid level of the curing liquid inside the fixed cylinder 6. The hollow sinking ball 1308 is located in the curing liquid inside the fixed cylinder 6, so that the curing liquid inside the fixed cylinder 6 can be discharged through the hollow sinking ball 1308, the water inlet hose 1307, the water outlet pressure valve 1305, the water outlet hose 1309 and the pressurized water valve 1306.

[0036] Furthermore, the inner end of the water outlet slide 1302 is spherical, and the spherical end of the water outlet slide 1302 contacts the inclined surface on the spiral sheet 11, so that when the inclined surface on the spiral sheet 11 contacts the spherical end of the water outlet slide 1302, the spiral sheet 11 can push the water outlet slide 1302 to move outward.

[0037] When in use, curing liquid is added to the water storage tank 2 through the water filling pipe 4, so that the curing liquid is first stored in the water storage tank 2. When the liquid level monitor on the automatic filling structure arranged inside the bridge box 7 detects that the liquid level inside the fixed cylinder 6 is low, the automatic filling structure can fill the curing liquid inside the water storage tank 2 into the fixed cylinder 6. When the curing liquid is filled to a certain amount, the filling is stopped, so that the liquid level of the curing liquid is above the hollow sinking ball 1308. At this time, the dust removal slide pipe 1202 is located above the liquid level of the curing liquid. When it is necessary to maintain the surface of a large volume of concrete, the mobile body 1 is manually pushed forward, and the motor 9 is started and the spiral piece 11 is driven to rotate through the rotating shaft 10. In the process of rotation of the spiral piece 11, it will not be mixed with the curing liquid that has sunk to the bottom of the fixed cylinder 6. The hollow bottom sinking ball 1308 and the water inlet hose 1307 in the fixed cylinder 6 interfere with each other, and the rotation of the spiral piece 11 can flip the curing liquid inside the fixed cylinder 6 to prevent the mixture in the curing liquid from sinking to the bottom. When the spiral piece 11 rotates, the inclined surface on the spiral piece 11 first contacts the spherical end of the dust removal slide pipe 1202. When the inclined surface on the spiral piece 11 is separated from the spherical end of the dust removal slide pipe 1202, the inclined surface on the spiral piece 11 contacts the spherical end of the water outlet slide pipe 1302 again. This cycle causes the inclined surface on the spiral piece 11 to alternately contact the dust removal slide pipe 1202 and the water outlet slide pipe 1302, and when the inclined surface on the spiral piece 11 contacts the spherical end of the dust removal slide pipe 1202, the spiral piece 11 can push the dust removal slide pipe 120 2 moves outward, and then the dust removal slide pipe 1202 can drive the dust removal pressure valve 1206 to move outward and deform the upper spring 1204. Because there is a pressure difference on both sides of the dust removal pressure valve 1206, and when the system pressure exceeds the set value of the dust removal pressure valve 1206, the valve will automatically open and release part of the gas to reduce the system pressure. When the system pressure drops to within the set range, the valve is closed. Therefore, when the dust removal slide pipe 1202 drives the dust removal pressure valve 1206 to move outward, the valve opens, and when it moves inward, the valve closes. When the dust removal slide pipe 1202 drives the dust removal pressure valve 1206 to move outward, the gas enters the dust removal pressure valve 1206 through the air inlet 1205 and the air collecting hood 1207, and the dust removal pressure valve 1206 is opened by the air guide soft The tube 1209 conveys the gas to the pressurized air valve 1208, and the pressurized air valve 1208 discharges the gas after pressurizing, so that the dust on the concrete surface can be blown away first, and then the dust on the concrete surface can be removed first. Similarly, when the inclined surface on the spiral blade 11 contacts the spherical end of the water outlet slide tube 1302, the spiral blade 11 can push the water outlet slide tube 1302 to move outward, and then the water outlet slide tube 1302 can drive the water outlet pressure valve 1305 to move outward and deform the lower spring 1304. Due to the pressure difference on both sides of the water outlet pressure valve 1305, when the system pressure exceeds the set value of the water outlet pressure valve 1305, the valve will automatically open and release part of the liquid to reduce the system pressure. When the system pressure drops to within the set range, the valve closes.Therefore, when the water outlet slide 1302 drives the water outlet pressure valve 1305 to move outward, the curing liquid enters the water outlet pressure valve 1305 through the hollow sinking ball 1308 and the water inlet hose 1307, and the water outlet pressure valve 1305 transports the curing liquid to the pressurized water valve 1306 through the water outlet hose 1309, and the pressurized water valve 1306 discharges the curing liquid after pressurization, so that the concrete surface after dust removal can be moistened, so that the curing liquid can fully contact the concrete surface, so as to improve the curing effect on the concrete.
