Description

Technical Field

[0001] The present invention relates to the technical field of ground leveling for housing construction, and specifically to a ground leveling device for building construction. Background Art

[0002] Building construction is a systematic construction process that transforms architectural designs into physical buildings through engineering techniques, covering multiple construction links such as foundation treatment, main structure, and decoration. Among them, ground leveling is a key process in the basic construction stage. The technical significance of this process lies in providing a basic guarantee for the construction accuracy of the subsequent ground structure layer by controlling technical parameters such as ground elevation deviation, flatness, and compaction degree, and at the same time meeting the requirements of functional indicators such as ground bearing capacity and drainage slope for the building's use function, which has an irreplaceable technical value for improving the overall quality and use safety of building projects.

[0003] Existing equipment for ground leveling during building construction usually drives a collective plate equipped with a leveling structure by a mobile trolley for leveling. The leveling structure mainly consists of a concrete blocking structure and a vibration flattening structure. The concrete blocking structure can prevent excessive concrete from accumulating and affecting the flattening effect of the vibration flattening structure, while the vibration flattening structure can ensure that the concrete is in a flat state, discharge air bubbles, and make the concrete more compact through vibration flattening.

[0004] Although the concrete leveling equipment disclosed in the prior art can achieve rapid leveling operations on the concrete surface, there are the following technical problems in the actual construction process: First, although the adopted blocking structure can block the excess concrete, there will be a situation where the concrete accumulates locally in front of the blocking structure. This accumulation phenomenon will continue to accumulate as the equipment moves, not only causing mechanical obstacles to the continuous progress of the mobile trolley, but also requiring additional manual cleaning procedures, increasing the labor intervention cost during the construction process and reducing the operation efficiency; at the same time, the lateral displacement of the accumulated concrete to the already leveled area may cause secondary interference to the flatness of the already formed surface, affecting the overall construction quality. Second, the pressing method of the existing equipment only relies on the mechanical action in the vertical direction. Although it can achieve the compaction effect of the concrete, it lacks effective means to control the multi-dimensional flatness of the concrete surface, resulting in the need for multiple repeated leveling operations during the construction process, prolonging the construction period and making it difficult to stably guarantee the flatness technical index of the concrete surface. Summary of the Invention

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A ground leveling device for building construction, including a mobile vehicle, the left side of the mobile vehicle is connected with a mounting plate through a connecting component. On the mounting plate, a tamping mechanism for tamping concrete and a flattening mechanism for flattening the tamped concrete are successively installed from right to left. At the left end of the mounting plate, a scraping mechanism for finally leveling the concrete is installed; the tamping mechanism includes obliquely arranged chutes linearly and evenly opened on the mounting plate. In each obliquely arranged chute, a mounting block is slidably connected along its own inclination direction. One ends of all the mounting blocks located on the upper side of the mounting plate are commonly connected with a synchronous plate. One end of each mounting block located on the lower side of the mounting plate is fixed with a tamping block. A pushing member is connected in the mounting block through a guiding member. When the mounting block slides downward and drives the tamping block to tamp the concrete through the guiding member, the pushing member is guided and the concrete is pushed forward and backward; the flattening mechanism includes a plurality of transmission columns vertically slidably connected to the mounting plate. The plurality of transmission columns are longitudinally and evenly distributed. A power member for driving the transmission columns to move up and down is fixed to the top of the mounting plate. A transmission member is connected between each transmission column and the synchronous plate. At the bottom of each transmission column, a flattening member capable of moving to flatten the concrete is provided.

[0006] Further, the power member includes a right-angle support plate fixed to the top of the mounting plate. A hydraulic cylinder is installed at the bottom of the horizontal section of the right-angle support plate. The telescopic end of the hydraulic cylinder is installed with a connecting plate, and the connecting plate is fixedly connected to all the transmission columns.

[0007] Further, the guiding member includes a limiting chute opened in the mounting block. A sliding block is slidably connected in the limiting chute along the inclination direction of the mounting block. A compression spring is connected between the sliding block and the top of the limiting chute. A compression structure is arranged between the sliding block and the mounting block. A guiding structure is connected between the bottom of the sliding block and the pushing member. The compression structure can drive the sliding block to generate a relative displacement during the movement of the mounting block, so as to guide the pushing member through the guiding structure and complete the forward and backward pushing of the concrete.

[0008] Further, the compression structure includes avoidance grooves symmetrically opened on the front and rear sides of the mounting block. Corresponding to each avoidance groove, a coordination rod is fixed on the side surface of the sliding block, and the coordination rod is slidably connected with the avoidance groove.

[0009] Further, the guiding structure includes a guiding plate fixed to the bottom of the sliding block. Guiding grooves are opened on the guiding plate corresponding to the position of the pushing member. The front and rear two guiding grooves are distributed in a shape of an eight. A follower rod for cooperating with the guiding groove is arranged on the pushing member.

[0010] Further, the pushing member includes a square groove group symmetrically opened on the upper and lower sides of the mounting block. Each group of square groove groups consists of square grooves symmetrically arranged front and back. A pushing block is slidably connected in each square groove. Coordination plates are symmetrically fixed above and below the pushing block corresponding to the position of the guiding member. The coordination plates symmetrically arranged above and below are fixedly connected to the corresponding follower rod together. A pushing structure is arranged between each pushing block and the mounting block.

[0011] Further, the pushing structure includes a receiving groove opened in the lower pushing block. A pushing block is connected in the receiving groove through a connecting spring. The mounting block is symmetrically fixed with a track plate with the pushing block as the axis corresponding to the position of the pushing block. A receiving push rod is fixed at the position of the pushing block corresponding to the track plate.

[0012] Further, the transmission member includes a horizontal sliding groove opened on the transmission column. A limiting sliding rod is horizontally slidably connected in the horizontal sliding groove. All the limiting sliding rods are fixedly connected to the synchronous plate.

[0013] Further, the scraping mechanism includes an L-shaped fixing plate fixed to the bottom of the mounting plate. A rotating scraping plate is hinged to the right end of the horizontal section of the L-shaped fixing plate. A torsion spring for keeping the rotating scraping plate inclined is installed between the rotating scraping plate and the horizontal section of the L-shaped fixing plate. A pushing plate is fixed to the left end of the limiting sliding rod in the middle position. The pushing plate is slidably connected to the mounting plate horizontally.

[0014] Further, the flattening member includes a limiting block opened at the bottom of the transmission column. A flattening plate is longitudinally slidably connected to the limiting block through a connecting rod. Longitudinal springs are symmetrically installed before and after between the flattening plate and the connecting rod. Track grooves are symmetrically opened before and after at the bottom of the mounting plate. Alignment rods are fixed at the positions of the top of the flattening plate corresponding to the track grooves. The flattening plate is driven to press back and forth and level through the cooperation of the alignment rods and the track grooves.

[0015] The beneficial effects of the present invention are as follows: First, through the series layout and sequential actions of the ramming mechanism, flattening mechanism and scraping mechanism, the step-by-step optimization of concrete treatment is realized. First, the ramming mechanism completes the oblique ramming and multi-directional pushing to initially compact the concrete and disperse the materials; then the flattening mechanism further compacts and evenly distributes the concrete through the dynamic flattening action; finally, the scraping mechanism performs a fine leveling treatment on the surface. The three work together to form a complete action of ramming first, then compacting, and finally scraping, so as to comprehensively improve the compactness, flatness and surface smoothness of the concrete.

[0016] Second, when the installation block moves downward along the inclined chute, the invention uses the ramming block to ram the concrete surface at an inclined angle. Under the action of the vertical pressure, a component force to the right is generated synchronously, which promotes the dispersion of the excess concrete and prevents local uplift of the concrete. At the same time, the inverted V-shaped structure of the guiding groove cooperates with the follower rod to drive the outer pushing block to move back and forth, and the inclined thrust generated by the pushing block guided by the track plate. The cooperation between the outer pushing block and the pushing block realizes the uniform spreading of the concrete in the front and back directions. In addition, through the multi-dimensional ramming actions of the ramming block, the outer pushing block and the pushing block, the air bubbles inside the concrete can be discharged, thereby improving the structural strength after the concrete solidifies, and at the same time improving the distribution uniformity of the concrete and the overall leveling effect, and avoiding the situation that the concrete moves to the area where the leveling has been completed and affects the overall leveling effect.

[0017] Third, when the alignment rod moves downward along the vertical section of the track groove, the invention uses the pressing plate to vertically compact the concrete with a constant pressure. The longitudinal spring buffers the pressure fluctuations to ensure the uniformity of compaction. At the same time, when the alignment rod enters the bent section of the track groove, the pressing plate moves back and forth under the hydraulic drive. Through the dynamic leveling action, the fine unevenness generated by ramming is eliminated, and at the same time, the close arrangement of concrete particles is promoted, thereby enhancing the overall density and improving the efficiency of leveling the concrete.

[0028] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product manual.

[0029] Refer to Figure 1 - Figure 2 , a ground leveling device for building construction, including a mobile vehicle 1. The left side of the mobile vehicle 1 is connected to a mounting plate 12 through a connecting component 11. An upper ramming mechanism 2 for ramming concrete and a flattening mechanism 3 for flattening the rammed concrete are sequentially installed on the mounting plate 12 from right to left. A scraping mechanism 4 for finally leveling the concrete is installed at the left end of the mounting plate 12.

[0030] It should be noted that the connecting component 11 is a prior art. The connecting component 11 includes a spring telescopic rod installed at the left end of the mobile vehicle 1. The telescopic end of the spring telescopic rod is fixed with a vertical plate, and the vertical plate is fixedly connected to the mounting plate 12. A bending rod is connected between the vertical plate and the bottom of the left end of the mobile vehicle 1, and the bending rod can rotate up and down. The spring telescopic rod adaptively adjusts the height of leveling.

[0031] The present invention drives the mounting plate 12, the ramming mechanism 2, the flattening mechanism 3 and the scraping mechanism 4 through the mobile vehicle 1 to perform ramming, flattening and final scraping actions on the concrete. Thus, through ramming, flattening and final scraping, the concrete is made compact, flat and the surface is made smooth and flat, ensuring the flatness and compactness of the concrete after leveling. At the same time, through ramming, the air bubbles inside the concrete can also be removed, improving the quality of the concrete after leveling.

[0032] Specifically, first, the mobile vehicle 1 with a traction structure drives the mounting plate 12, the ramming mechanism 2, the flattening mechanism 3, and the scraping mechanism 4 through the connecting assembly 11 to move from left to right and level the laid concrete. Among them, the ramming mechanism 2 will first ram and press the concrete, making the concrete more compact. Subsequently, the flattening mechanism 3 presses the concrete again. After the concrete is compacted by the flattening mechanism 3, the scraping mechanism 4 finally scrapes the compacted and leveled concrete. The surface of the concrete after being scraped is completely flat.

[0033] Refer to Figure 2 - Figure 4 , the ramming mechanism 2 includes obliquely arranged chutes 21 linearly and uniformly formed on the mounting plate 12. Each obliquely arranged chute 21 is slidably connected with a mounting block 211 along its own inclined direction. One ends of all the mounting blocks 211 located on the upper side of the mounting plate 12 are commonly connected with a synchronous plate 212. One end of each mounting block 211 located on the lower side of the mounting plate 12 is fixed with a ramming block 213. A pushing member 23 is connected in the mounting block 211 through a guiding member 22.

[0034] During the process that the guiding member 22 guides the pushing member 23 and completes the forward and backward pushing of the concrete when the mounting block 211 slides downward and drives the ramming block 213 to ram the concrete, the concrete is rammed by the ramming block 213. The ramming method can not only make the concrete compacted under pressure, but also make the concrete move to the right and disperse before being rammed through the cooperation of the inclined mounting block 211 and the ramming block 213 with the obliquely arranged chute 21, avoiding the situation that a large amount of concrete accumulates and bulges after being rammed and compacted. Moreover, the ramming method can remove the air bubbles in the concrete and improve the quality of the concrete after solidification.

[0035] Specifically, during the process that the mobile vehicle 1 moves from left to right, the synchronous plate 212 moves downward along the direction of the obliquely arranged chute 21 under the synchronous pushing action of the flattening mechanism 3. At this time, the synchronous plate 212 will synchronously drive the mounting block 211 and the ramming block 213 to move downward. When the ramming block 213 first contacts the concrete, it will first push the overly accumulated concrete to the right and ram it. During the process that the mounting block 211 and the ramming block 213 move downward, the guiding member 22 will guide the pushing member 23 and push the concrete forward and backward.

[0036] Refer to Figure 2 - Figure 6, the guiding member 22 includes a limiting chute 221 formed in the mounting block 211. A sliding block 222 is connected in the limiting chute 221 in a limiting sliding manner along the inclined direction of the mounting block 211. A compression spring is connected between the sliding block 222 and the top of the limiting chute 221. A compression structure is provided between the sliding block 222 and the mounting block 211. A guiding structure is connected between the bottom of the sliding block 222 and the pushing member 23. The compression structure can drive the sliding block 222 to have a relative displacement during the movement of the mounting block 211, so as to guide the pushing member 23 through the guiding structure to complete the forward and backward pushing of the concrete.

[0037] The compression structure includes avoidance grooves 223 symmetrically formed in the front and rear of the mounting block 211. A coordination rod 224 is fixed to the side surface of the sliding block 222 corresponding to each avoidance groove 223. The coordination rod 224 is slidably connected to the avoidance groove 223. The guiding structure includes a guiding plate 225 fixed to the bottom of the sliding block 222. Guiding grooves 226 are formed in the guiding plate 225 at positions corresponding to the pushing member 23. The front and rear two guiding grooves 226 are distributed in a shape of an eight. A follower rod 227 matching the guiding groove 226 is provided on the pushing member 23.

[0038] The pushing member 23 includes a square groove group symmetrically formed in the front and rear of the mounting block 211. Each group of square groove groups is composed of square grooves symmetrically formed in the front and rear. An outer pushing block 231 is slidably connected in each square groove. Coordination plates 232 are symmetrically fixed to the positions of the outer pushing blocks 231 corresponding to the guiding member 22 in the up and down directions. The coordination plates 232 symmetrically fixed in the up and down directions are jointly fixed to the corresponding follower rod 227. A pushing structure is provided between each outer pushing block 231 and the mounting block 211. The pushing structure includes a receiving groove 233 formed in the lower outer pushing block 231. A pushing block 234 is connected in the receiving groove 233 through a connecting spring. A track plate 235 is symmetrically fixed to the position of the mounting block 211 corresponding to the pushing block 234 with the pushing block 234 as the axis of symmetry. A receiving push rod 236 is fixed to the position of the pushing block 234 corresponding to the track plate 235.

[0039] The concrete is pushed by the cooperation of the guiding member 22 and the pushing member 23. At the same time, the front and rear two pushing blocks 234 cooperate with the longitudinal pushing of the outer pushing blocks 231 in an oblique pushing manner to comprehensively push the concrete, so that the front and rear distribution of the concrete is more uniform. And in cooperation with the oblique pushing of the tamping block 213, the situation that the concrete accumulates in one place is further avoided, and at the same time, the concrete is made more compact and the air bubbles mixed in it are discharged.

[0040] Specifically, when the synchronization plate 212 is pushed and drives the mounting block 211 and the ramming block 213 to move downward, when the coordination rod 224 contacts the mounting plate 12, it will stop moving downward, while the mounting block 211 will continue to move downward, causing a relative displacement between the mounting block 211 and the mounting plate 12. At this time, the guide plate 225 will move upward relative to the outer pushing block 231 and the coordination plate 232, so as to press the follower rod 227 through the guide groove 226 and cause the outer pushing block 231 and the coordination plate 232 to move outward. As the outer pushing block 231 moves outward, the pushing block 234 will move synchronously with the outer pushing block 231. During this process, the connecting spring is continuously pressed and generates a continuous elastic force applied to the pushing block 234. At this time, due to the guiding action of the track plate 235 and the elastic force of the connecting spring, the pushing block 234 slides along the receiving groove 233, and the pushing block 234 can extend and complete further ramming during the process of moving forward and backward with the outer pushing block 231, and then cooperate with the ramming block 213 and the outer pushing block 231 to comprehensively ram the concrete, ensuring the compactness of the concrete after ramming and discharging air bubbles.

[0041] Refer to Figure 2 、 Figure 3 Figure 5 、 Figure 7 and Figure 8 ,The flattening mechanism 3 includes a plurality of transmission columns 31 vertically and slidably connected to the mounting plate 12. The plurality of transmission columns 31 are longitudinally and evenly distributed. A power member 32 for driving the transmission columns 31 to move up and down is fixed to the top of the mounting plate 12. A transmission member 33 is connected between each transmission column 31 and the synchronization plate 212. A flattening member 34 capable of moving to flatten the concrete is provided at the bottom of each transmission column 31.

[0042] The power member 32 includes a right-angle support plate 321 fixed to the top of the mounting plate 12. A hydraulic cylinder 322 is installed at the bottom of the horizontal section of the right-angle support plate 321. A connecting plate 323 is installed at the telescopic end of the hydraulic cylinder 322. The connecting plate 323 is fixedly connected to all the transmission columns 31; the transmission member 33 includes a horizontal chute 331 opened on the transmission column 31. A limiting slide rod 332 is horizontally slidably connected in the horizontal chute 331. All the limiting slide rods 332 are fixedly connected to the synchronization plate 212.

[0043] The flattening member 34 includes a limiting block 341 opened at the bottom of the transmission column 31. A flattening plate 343 is longitudinally slidably connected to the limiting block 341 through a connecting rod 342. Longitudinal springs are symmetrically installed before and after between the flattening plate 343 and the connecting rod 342. Trajectory grooves 344 are opened on both the front and rear sides of the bottom of the mounting plate 12. The trajectory grooves 344 are composed of a vertical section and a bent section. Alignment rods 345 are fixed at the positions corresponding to the trajectory grooves 344 on the top of the flattening plate 343. The alignment rods 345 cooperate with the trajectory grooves 344 to drive the flattening plate 343 to press and smooth back and forth.

[0044] The flattening mechanism 3 can complete the flattening action of the concrete after tamping the concrete. The power member 32 drives the flattening member 34 to reciprocate up and down continuously to complete the flattening action. At the same time, the way that the flattening member 34 reciprocates back and forth during the flattening process can ensure the flatness of the concrete and enhance the leveling effect. At the same time, the flattening member 34 can further compact the concrete to ensure the flatness and firmness of the ground after leveling.

[0045] Specifically, as the mobile vehicle 1 moves from left to right, the control hydraulic cylinder 322 continuously drives the connecting plate 323 to reciprocate up and down. At this time, the connecting plate 323 will synchronously drive all the transmission columns 31 to reciprocate up and down. During the movement of all the transmission columns 31, the limiting slide rod 332 will be synchronously driven by the transmission column 31 and drive all the mounting blocks 211 to move downward synchronously through the synchronous plate 212; when the concrete is tamped and compacted by the tamping mechanism 2, the transmission column 31 will move to the position of the tamped concrete. During the downward movement of the transmission column 31, the alignment rod 345 will first move vertically downward under the guiding action of the vertical section of the trajectory groove 344 and drive the flattening plate 343 to move vertically downward. When the alignment rod 345 moves to the bent section of the trajectory groove 344, the alignment rod 345 will drive the flattening plate 343 to reciprocate back and forth under the common guiding action of the bent sections of the front and rear trajectory grooves 344. At this time, since the bottom of the flattening plate 343 has come into contact with the concrete, the reciprocating smoothing action of the flattening plate 343 can not only make the front and rear distribution of the concrete more uniform, but also make the concrete compacted under pressure, thereby ensuring the compaction and flatness of the concrete.

[0046] Refer to Figure 2 and Figure 5 As shown in, the scraping mechanism 4 includes an L-shaped fixing plate 41 fixed to the bottom of the mounting plate 12. The right end of the horizontal section of the L-shaped fixing plate 41 is hinged with a rotating scraping plate 411. A torsion spring for keeping the rotating scraping plate 411 inclined is installed between the rotating scraping plate 411 and the horizontal section of the L-shaped fixing plate 41. A pushing plate 412 is fixed to the left end of the limiting slide rod 332 in the middle position. The pushing plate 412 is slidably connected to the mounting plate 12.

[0047] The scraping mechanism 4 is used to finally level the concrete. By this leveling method, not only can the concrete be ensured to be in a flat state, but also the combination of the rotating scraping plate 411 and the horizontal section of the L-shaped fixing plate 41 for leveling can ensure that the top of the concrete is in a flat state through dynamic and static leveling methods. And due to the pushing action of the pushing plate 412, the rotating scraping plate 411 can only perform the combined leveling action when the pressing plate 343 moves to the lowest position, so that the pressing plate 343 and the rotating scraping plate 411 cooperate to perform the leveling action, avoiding the escape of concrete during the process of being pressed and leveled, and preventing the situation that the surface of the concrete after leveling is still uneven.

[0048] Specifically, during the downward movement of the transmission column 31, the limit slide bar 332 will move downward synchronously. However, due to the limiting effects of the synchronous plate 212 and the mounting block 211 connected to the limit slide bar 332, the limit slide bar 332 will move to the right. At this time, the top of the rotating scraping plate 411 can be pressed by the pushing plate 412, causing the rotating scraping plate 411 to deflect to the leveling position. At this time, the pressing plate 343 reciprocates back and forth to level the concrete, and the concrete that escapes under the pressing of the pressing plate 343 will be scraped by the rotating scraping plate 411 and fit with the concrete surface, ensuring that the top of the concrete is in a flat state.

[0049] The working steps of the present invention are as follows: First step, first evenly lay the concrete on the construction ground, and then drive the mounting plate 12 and the tamping mechanism 2, the flattening mechanism 3 and the scraping mechanism 4 thereon to move from left to right for leveling by the moving vehicle 1 with a traction structure; during this process, the spring telescopic rod and the bending rod of the connecting component 11 cooperate to maintain the stable connection of the mounting plate 12, ensuring the smooth progress of the leveling device.

[0050] Second step, during the process of the moving vehicle 1 moving from left to right, first, the hydraulic cylinder 322 of the power component 32 is used to push the connecting plate 323 to reciprocate up and down and drive all the transmission columns 31 to move synchronously. During this process, the horizontal chute 331 of the transmission component 33 and the limit slide bar 332 form a linkage relationship, converting the vertical movement of the transmission column 31 into the obliquely downward movement of the synchronous plate 212.

[0051] Third step, as the synchronous plate 212 moves obliquely downward along the inclined chute 21, the synchronous plate 212 will drive the mounting block 211 and the tamping block 213 to complete the oblique tamping action; at this time, the guiding component 22 drives the outer pushing block 231 of the pushing component 23 to move outward through the cooperation of the limit chute 221 and the sliding block 222 and the eight-shaped guiding groove 226; during this process, the pushing structure forms an oblique pushing force under the guidance of the track plate 235, cooperating with the oblique action of the tamping block 213 to achieve three-dimensional tamping in the front-back and oblique directions, effectively dispersing the concrete accumulation and discharging air bubbles.

[0052] Step 4: When the driving column 31 moves downward, the concrete that has been tamped and pressed will then correspond to the position of the flattening member 34. The alignment rod 345 of the flattening member 34 moves along the bent section of the track groove 344, driving the flattening plate 343 to perform reciprocating flattening back and forth; at this time, the longitudinal spring and the connecting rod 342 form an elastic flattening structure, completing the back-and-forth smoothing action while maintaining a constant pressure; at this stage, the surface of the concrete after tamping and pressing is further compacted and leveled.

[0053] Step 5: When the flattening plate 343 presses down to the lowest point, the driving column 31 pushes the push plate 412 to move rightward through the limit slide rod 332, releasing the limit on the rotating scraping plate 411; at this time, the L-shaped fixing plate 41 and the rotating scraping plate 411 that has returned to the horizontal form a combined scraping structure to finally smooth the concrete that escapes after flattening; the inclination angle maintained by the torsion spring enables the scraping plate to automatically adjust the contact pressure during dynamic movement, ensuring that a smooth and flat surface layer is formed on the concrete surface.

[0054] 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, and still be covered by the protection scope of the present invention.
