Description

Technical Field

[0001] The present invention relates to the technical field of construction of emery floors, and in particular to a construction device for controlling cracks in emery floors. Background Art

[0002] Emery floor is a common name for wear-resistant hardened floors in China, which has the advantages of wear resistance, compression resistance, dust reduction, hard surface, easy cleaning, economy and durability. The emery floor material is a dry-spread floor hardener that is pre-mixed in the factory and ready to use on site. During construction, it is evenly spread on the surface of the concrete in the initial setting stage. After overall curing, it forms a dense whole and a super-hardened surface layer with the concrete floor, which is a high-performance wear-resistant floor with compression resistance, impact resistance, wear resistance, high precision and coloring.

[0003] However, for traditional manual material spreading, the construction time is relatively long, the labor intensity is high, and it is inevitable to have footprints and uneven spreading of wear-resistant materials. Due to the appearance of footprints during manual material spreading, only the method of covering with floating slurry can be adopted in the slurry lifting and finishing processes. After long-term use of the floor, due to the different compactness of the floating slurry at the footprint area and the concrete base layer at the footprint area, the initial shrinkage ratio is uneven and the long-term surface load is uneven, resulting in cracking at the contact surface.

[0042] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0043] Embodiment 1:

[0044] As shown in the appended Figure 1 to the appended Figure 11As shown in the figure, the present invention provides a construction device for controlling cracks in a carborundum floor, including a bottom plate 1, with counterweight blocks 2 arranged on both sides of its top, a cavity column 3 welded to the middle of the upper part of the bottom plate 1, a lifting mechanism 4 arranged inside the cavity column 3 for adjusting the height between the material spreading mechanism 12 and the construction area, an adjusting mechanism 5 horizontally arranged outside the lifting mechanism 4 for extending the material spreading mechanism 12 above the area to be constructed, a bearing plate 6 welded to one end of the adjusting mechanism 5 away from the bottom plate 1, with a storage hopper 7 and a discharge pipe 9 communicating with each other from top to bottom at its top. The storage hopper 7 contains gravel, a stirring mechanism 8 arranged inside the storage hopper 7 for stirring the gravel in the storage hopper 7 to prevent the gravel from caking, a feeding mechanism 10 arranged inside the discharge pipe 9 for quantitatively feeding the gravel to prevent the gravel from accumulating in the treatment box 11, a treatment box 11 welded below the bearing plate 6, with a through groove 601 opened on the outside of the bearing plate 6, and the treatment box 11 communicates with the discharge pipe 9 through the through groove 601, and a material spreading mechanism 12 arranged inside the treatment box 11 for evenly spreading the gravel onto the area to be constructed. The top of the storage hopper 7 is communicated with a feed pipe 701.

[0045] As can be seen from the above, when using the device, first move the device to the side of the area to be constructed through the wheels under the bottom plate 1, and let the gravel to be spread fall into the storage hopper 7 through the feed pipe 701. Then adjust the overall height of the device through the lifting mechanism 4 to make the device adapt to the height of the area to be constructed. Then, through the adjusting mechanism 5, the device can be horizontally contracted along the area to be constructed. During this process, the stirring mechanism 8 breaks up the caked gravel in the storage hopper 7, and the feeding mechanism 10 drops an appropriate amount of gravel into the treatment box 11 through the discharge pipe 9. Finally, through the material spreading mechanism 12, not only can the gravel be evenly spread onto the target horizontal area, but also the impurities or non-standard gravel in the gravel can be selected and collected, further improving the practicability of the device. When the spreading of a certain horizontal area is completed, the device can be moved to the next horizontal area through the wheels until the spreading of gravel in all areas is completed, avoiding the need for workers to step on the not fully solidified concrete, resulting in large footprints and uneven shrinkage ratios of concrete and gravel in subsequent construction, thus causing cracks in the carborundum floor.

[0046] Embodiment 2:

[0047] As attached Figure 2As shown in the figure, this embodiment is basically the same as the previous one, except that the lifting mechanism 4 includes a movable column 401 arranged inside the cavity column 3. A first chute 402 is formed on one inner wall of the cavity column 3. A slider 403 is welded to the outer side of the bottom of the cavity column 3. The cavity column 3 slides in the first chute 402 through the slider 403. An arc-shaped toothed plate 404 is welded to the outer side of the movable column 401. An installation vertical plate 405 is welded to the outer side of the cavity column 3. A first stepping motor 406 is fixedly installed on the rear side of the installation vertical plate 405. The output end of the first stepping motor 406 extends to the front side of the installation vertical plate 405 and is fixedly connected to a first gear 407. The first gear 407 is meshed and connected with the arc-shaped toothed plate 404.

[0048] As can be seen from the above, when the device needs to be lifted to be adapted to the height of the construction area to be constructed, the first stepping motor 406 is turned on. The first stepping motor 406 drives the first gear 407 to rotate. The first gear 407 drives the movable column 401 to rise inside the cavity column 3 through the arc-shaped toothed plate 404 welded to the first gear 407. By sliding the slider 403 along the first chute 402, the turning amplitude of the movable column 401 in the cavity column 3 is limited, improving the stability of the lifting of the movable column 401. Furthermore, the adjustment mechanism 5 and the bearing plate 6 drive the treatment box 11 to rise stably in the construction area to be constructed, enabling the device to adapt to the construction operation requirements of different heights.

[0049] Embodiment Three:

[0050] As shown in the attached Figure 3 to the attached Figure 5 As shown in the figure, this embodiment is basically the same as the previous one, except that the adjustment mechanism 5 includes a cavity block 501 welded to the top of the movable column 401. A first sliding plate 502 is slidably connected inside the cavity block 501. A second sliding plate 503 is slidably connected inside the first sliding plate 502. A second stepping motor 504 is fixedly installed on the top of the cavity block 501. The output end of the second stepping motor 504 is fixedly connected to a second gear 505. A straight toothed plate 506 is welded to the top of the first sliding plate 502. The straight toothed plate 506 is meshed and connected with the second gear 505. A first connecting rod 507 is rotatably connected to the front side of the cavity block 501. A second connecting rod 508 is rotatably connected to the front side of the second sliding plate 503. The intersection of the first connecting rod 507 and the second connecting rod 508 is rotatably connected to a telescopic rod 509 through a pin shaft. The first connecting rod 507, the second connecting rod 508 and the telescopic rod 509 are all rotatable relative to each other. A matching groove 510 is formed on the front side of the first sliding plate 502. A matching block 511 is slidably connected inside the matching groove 510. The matching block 511 is rotatably connected to the extending end of the telescopic rod 509.

[0051] As described above, when the device is horizontally contracted along the area to be constructed, the second stepping motor 504 is turned on. The second stepping motor 504 drives the second gear 505 to rotate. Through the straight tooth plate 506 connected by meshing, the first sliding plate 502 is driven to slide out along the direction of the cavity block 501. During the sliding process of the first sliding plate 502, the matching block 511 drives the telescopic rod 509 to rotate and contract along the matching groove 510. Then, through the first connecting rod 507 and the second connecting rod 508, the second sliding plate 503 is driven to slide out from the first sliding plate 502. Through the two-stage sliding of the first sliding plate 502 and the second sliding plate 503, the processing box 11 can cover the area to be constructed to the greatest extent, thus completing the subsequent construction operations.

[0052] Embodiment 4:

[0053] As shown in the attached Figure 6 to the attached Figure 7 figures, this embodiment is basically the same as the previous embodiment. The difference is that the stirring mechanism 8 includes a first driving motor 801 fixedly installed on the top of the storage tank 7. The output end of the first driving motor 801 extends into the interior of the storage tank 7 and is fixedly connected with a first connecting rod 802. On opposite sides of the outer surface of the first connecting rod 802, a number of groups of stirring fan blades 803 with opposite inclination angles are linearly arranged. The feeding mechanism 10 includes an L-shaped mounting plate 101 welded to the outside of the discharge pipe 9. A third stepping motor 102 is fixedly installed on the outside of the L-shaped mounting plate 101. The output end of the third stepping motor 102 extends into the interior of the discharge pipe 9 and is fixedly connected with a first bevel gear 103. The first bevel gear 103 is meshed with a second bevel gear 104 on the outside. The bottom of the second bevel gear 104 is fixedly connected with a second connecting rod 105. The outside of the second connecting rod 105 is rotatably connected to a connecting disk 106 through a bearing, and the connecting disk 106 is fixedly connected with the discharge pipe 9. One end of the second connecting rod 105 away from the second bevel gear 104 is fixedly connected with a worm 107.

[0054] As described above, when the device is horizontally contracted along the area to be constructed, the first driving motor 801 is turned on. The first driving motor 801 drives the first connecting rod 802 to rotate. The stirring fan blades 803 on both sides with opposite inclination angles fully stir the gravel that may form lumps inside the storage tank 7. Then, the third stepping motor 102 is turned on. The third stepping motor 102 drives the first bevel gear 103 to rotate, causing the second bevel gear 104 to rotate. The second bevel gear 104 drives the worm 107 to rotate through the second connecting rod 105. Since the worm 107 is in contact with the inner wall of the discharge pipe 9, the gravel is quantitatively dropped into the processing box 11 through the worm 107, avoiding the problem of excessive gravel in a local construction area.

[0055] Embodiment 5:

[0056] As shown in the attached Figure 8 to the attached Figure 11As shown in the figure, this embodiment is basically the same as the previous one. The difference is that the material spreading mechanism 12 includes chute two 1201 opened on the inner walls of the opposite sides of the processing box 11. A tension spring 1202 is arranged inside the chute two 1201. One end of the tension spring 1202 is fixed to the inner wall of the processing box 11, and the other end of the tension spring 1202 is fixedly connected with a connecting block 1203. The connecting block 1203 slides in the chute two 1201. The outer sides of the connecting block 1203 are fixedly connected with leakage plates 1204. The outer surface of the leakage plate 1204 is arrayed with notches adapted to standard gravel. A second driving motor 1205 is fixedly installed on the front side of the processing box 11. The output end of the second driving motor 1205 extends into the processing box 11 and is fixedly connected with a rotating rod 1206. The end of the rotating rod 1206 away from the second driving motor 1205 is fixedly connected with a cam 1207. The cam 1207 abuts against the leakage plate 1204. The outer side of the processing box 11 is rotatably connected with a movable plate 1208 through a hinge 1209. One side of the processing box 11 is fixedly connected with two groups of support members 1210. The two groups of support members 1210 are fixedly connected with a connecting member 1212 through a thrust spring 1211. The connecting member 1212 is fixedly connected to the outer side of the movable plate 1208. Two groups of cylinders 1213 are fixedly installed on the outer side of the processing box 11. The piston rods of the two groups of cylinders 1213 extend into the processing box 11 and are fixedly connected with a push plate 1214. A collection box 1215 is quickly disassembled on the outer surface of the processing box 11 and below the movable plate 1208.

[0057] As can be seen from the above, after the gravel is quantitatively dropped into the processing box 11, the second driving motor 1205 is started. The second driving motor 1205 drives the cam 1207 to rotate through the rotating rod 1206. The connecting block 1203 is continuously pulled by the tension spring 1202. The connecting block 1203 is fixedly connected with the leakage plate 1204. Thus, the leakage plate 1204 always abuts against the cam 1207. As the cam 1207 rotates, the gravel above the leakage plate 1204 vibrates at a high frequency. Then, through the notches opened on the outer surface of the leakage plate 1204, the standard gravel falls through the notches to the construction area. When there are more impurities or large-grained gravel above the leakage plate 1204, the two groups of cylinders 1213 are started. The two groups of cylinders 1213 drive the push plate 1214 to move towards the movable plate 1208. At this time, the leakage plate 1204 rises to the maximum value and fits with the push plate 1214. Thus, the impurities or large-grained gravel above the leakage plate 1204 can be pushed out through the movable plate 1208 and then fall into the collection box 1215. When the two groups of cylinders 1213 drive the push plate 1214 to reset, the movable plate 1208 enters the collection box 1215 again through the thrust of the thrust spring 1211. Thus, it is avoided that the granular sand spills from the side during high-frequency vibration.

[0058] Working principle: When using the device, first move the device to the side of the construction area to be constructed through the wheel body under the bottom plate 1, and let the gravel to be scattered fall into the storage tank 7 through the feed pipe 701. When it is necessary to lift the device to match the height of the construction area to be constructed, turn on the first stepping motor 406. The first stepping motor 406 drives the first gear 407 to rotate. The first gear 407 drives the movable column 401 to rise inside the cavity column 3 through the arc-shaped tooth plate 404 welded to the first gear 407. The slider 403 slides along the first chute 402, which limits the turning amplitude of the movable column 401 inside the cavity column 3 and improves the stability of the lifting of the movable column 401. Then, through the adjusting mechanism 5 and the bearing plate 6, the processing box 11 is stably lifted in the construction area to be constructed, so that the device can adapt to the construction operation requirements of different heights;

[0059] When the device is horizontally contracted along the construction area to be constructed, turn on the second stepping motor 504. The second stepping motor 504 drives the second gear 505 to rotate. The first slide plate 502 slides out along the cavity block 501 through the spur gear plate 506 connected by meshing. During the sliding process of the first slide plate 502, the matching block 511 drives the telescopic rod 509 to rotate and contract along the matching groove 510. Then, through the first connecting rod 507 and the second connecting rod 508, the second slide plate 503 slides out of the first slide plate 502. Through the two-stage sliding of the first slide plate 502 and the second slide plate 503, the processing box 11 can cover the construction area to be constructed as much as possible, so as to complete the subsequent construction operations;

[0060] When the device is horizontally contracted along the construction area to be constructed, turn on the first driving motor 801. The first driving motor 801 drives the first connecting rod 802 to rotate. The stirring fan blades 803 on both sides with opposite inclination angles fully stir the gravel that may agglomerate inside the storage tank 7. Then, turn on the third stepping motor 102. The third stepping motor 102 drives the first bevel gear 103 to rotate, so that the second bevel gear 104 rotates. The second bevel gear 104 drives the worm 107 to rotate through the second connecting rod 105. Since the worm 107 is attached to the inner wall of the discharge pipe 9, the gravel is quantitatively dropped into the processing box 11 through the worm 107, avoiding the problem of too much gravel in a local construction area;

[0061] After the sand and gravel are quantitatively dropped into the treatment box 11, the second driving motor 1205 is started. The second driving motor 1205 drives the cam 1207 to rotate through the rotating rod 1206, continuously pulls the connecting block 1203 through the tension spring 1202, and the connecting block 1203 is fixedly connected to the leakage plate 1204, so that the leakage plate 1204 always abuts against the cam 1207. With the rotation of the cam 1207, the sand and gravel above the leakage plate 1204 vibrate at a high frequency, and then the standard sand and gravel fall to the construction area through the notches formed on the outer surface of the leakage plate 1204. When there are more impurities or large-particle sand and gravel above the leakage plate 1204, two groups of cylinders 1213 are started. The two groups of cylinders 1213 drive the push plate 1214 to move towards the movable plate 1208. At this time, the leakage plate 1204 rises to the maximum value and fits with the push plate 1214, so that the impurities or large-particle sand and gravel above the leakage plate 1204 can be pushed out through the movable plate 1208 and then fall into the collection box 1215. When the two groups of cylinders 1213 drive the push plate 1214 to reset, the movable plate 1208 enters the collection box 1215 again under the thrust of the thrust spring 1211, thus avoiding the situation that the sand grains are scattered from the side during high-frequency vibration.

[0062] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
