Description

Technical Field

[0001] This invention relates to the field of building construction ground leveling technology, specifically to a building construction ground leveling equipment and method. Background Technology

[0002] The construction cost of cement road surface is lower than that of asphalt road. The pouring of cement can be carried out on site, and the cement mixing and pouring process can be carried out on site. The construction difficulty is also relatively small. The standard for cement road surface is usually the needs of rural road construction. The standard bricks are usually 3.5m-5m in size. After the road surface is poured, it is usually necessary to use a round roller to roll back and forth on the road surface to achieve the leveling process, or directly use a vibratory machine to level it.

[0003] Because the road width is not uniform, some fixed-size rollers and scrapers cannot be used normally when pouring the road. Rolling or scraping the whole area first, and then using a vibratory machine or trowel to level a small area of ​​the road will reduce the overall flatness of the road. During the road leveling operation, due to the different road paving materials, depressions will appear when leveling the ground, which need to be repaired and leveled by workers one by one, resulting in a decrease in the overall flatness efficiency of the construction ground.

[0004] Therefore, we propose a device and method for leveling the ground during building construction. Summary of the Invention

[0005] The purpose of this invention is to provide a construction site leveling device and method to solve the problems mentioned in the background art, such as the fixed size of construction site leveling devices, which cannot be applied to road leveling of different spans, and the inability to repair some sunken areas during road leveling.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A construction site ground leveling device includes a movable support frame arranged symmetrically. A placement plate is slidably connected to the outer wall of the movable support frame. A rotating sleeve is fixedly connected to one side of the placement plate by bolts, and a fixed cover is movably connected to the inner wall of one side of the rotating sleeve. A connecting cover one is fixedly fixed to the bottom of one fixed cover by bolts, and a connecting cover two is fixedly fixed to the bottom of the other fixed cover by bolts. A motor is fixedly fixed to the top of the fixed cover by bolts. Rollers are symmetrically fixed to the bottom of the connecting cover one and the connecting cover two by bolts.

[0008] The first connecting cover and the second connecting cover are slidably connected. The top of the first connecting cover is slidably connected to a sliding mechanism, which includes a housing, a storage cylinder, a leveling roller, and a pressing block. The top of the first connecting cover is slidably connected to the housing, and the storage cylinder is fixed to the inner wall of the housing by bolts. One side of the storage cylinder is connected to a flow control tube, and one end of the flow control tube penetrates the bottom of the housing. A laser profilometer is fixed to one side of the flow control tube and to the inner wall of the bottom of the housing by bolts. The inner wall of the bottom of the housing is equipped with a leveling roller, and one end of the leveling roller penetrates the housing and is movably connected to the housing. The bottom of the housing is movably connected to the pressing block through a bearing.

[0009] Furthermore, a toothed plate is fixed to one inner wall of the first connecting cover by bolts, and a toothed plate is fixed to one inner wall of the second connecting cover by bolts, and is slidably connected to the first toothed plate on one side of the second toothed plate. One side of the first toothed plate is meshed with the side of the gear connected to the pressing block inside the housing. One side of the second toothed plate is meshed with the gear connected to the outer wall of the flattening roller inside the housing. A through groove is opened on one side of the first connecting cover and the second connecting cover, corresponding to the first toothed plate and the second toothed plate.

[0010] Furthermore, the motor output end of the top of the connecting cover one passes through the fixed cover and is fixed with a transmission wheel two by spot welding. The motor output end of the top of the connecting cover two passes through the fixed cover and is fixed with a transmission wheel one by spot welding. A transmission belt is sleeved on the transmission wheel one and the transmission wheel two. One side of the transmission belt passes through the housing and is fixed to the housing. A buffer wheel is symmetrically fixed to the bottom of the housing by bolts, and the bottom of the buffer wheel abuts against the top of the connecting cover.

[0011] Furthermore, a reinforcing rib is fixed to one side of the first connecting cover by bolts, a fixing sleeve is fixed to one side of the second connecting cover by bolts, and a limiting groove is opened on one side of the fixing sleeve. A sleeve is fixed to one side of the reinforcing rib by bolts, and a fixing cylinder is slidably connected inside the sleeve. A spring is installed on the opposite side of the fixing cylinder and the sleeve. One side of the fixing cylinder passes through the sleeve and is engaged with the limiting groove.

[0012] Furthermore, an adjustment box is fixedly fitted onto the outer wall of the movable bracket, and a toothed column is slidably connected to the inner wall of one side of the adjustment box. One end of the toothed column passes through the adjustment box and is connected to the placement plate by bolts. A toothed rod is slidably connected to the inner wall of one side of the adjustment box, and a rotating arm is slidably connected to the outer wall of one side of the adjustment box. One end of the rotating arm passes through the adjustment box and is fixed to one side of the toothed rod. Limiting rods are rotatably connected to the inner walls of both sides of the adjustment box through bearings, and limiting tooth blocks are fixed by spot welding on the side opposite to the limiting rod and the toothed column. A spring is installed on the inner wall of the bottom of the adjustment box, and the top of the spring abuts against the limiting rod.

[0013] The method for leveling the construction site is as follows:

[0014] Height and width calibration: The operator pushes the rotating arm on both sides of the movable support and rotates it downwards. At the same time, the operator pulls the rotating arm back and lifts it upwards, so that the toothed column in the adjustment box drives the placement plate to move upwards. Correspondingly, the fixed cover connected to one side of the placement plate drives the connecting cover one and connecting cover two to rise simultaneously. Then, the bottom rollers of the entire connecting cover one and connecting cover two are set on both sides of the ground to be leveled, so that the leveling roller and the pressing block are 10mm below the ground.

[0015] At the same time, press down on the two fixed cylinders located on the fixed sleeve, and at the same time, the operators on both sides push the connecting cover one and the connecting cover two inward so that one side of the roller is aligned with the edge of the road surface.

[0016] The moving and rotating pressing mechanism activates the transmission device at the bottom of the movable support, causing connecting cover one and connecting cover two to move a certain distance. Simultaneously, the motor drives the transmission wheels one and two inside connecting cover one and connecting cover two to rotate, causing the leveling roller and pressing block installed on the transmission belt to begin moving left and right along with the housing on connecting cover one and connecting cover two. As the leveling roller and pressing block move, they come into contact with toothed plate one and toothed plate two. The rotating leveling roller begins to rotate as it moves, pushing the concrete paved on the road surface to one side, while the pressing block smooths the road surface.

[0017] During quantitative filling, as the entire shell moves between the top of connecting cover one and connecting cover two, the laser profiler measures the road surface flatness information and feeds it back to the control box on the movable support. The control signal generated by the control box enables the fixed-point discharge operation of the flow control tube, and finally, the material is smoothed uniformly by pressing blocks.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, by rotating the rotating arm located on the adjustment box, the height of the entire placement plate relative to the movable support can be adjusted, ultimately achieving the combined height of the entire connecting cover one and connecting cover two. At the same time, pressing the fixed cylinder located on the reinforcing rib causes the entire movable support to rotate relative to each other and push inwards, thereby adjusting the width of the combined cover of the entire connecting cover one and connecting cover two. This allows the entire connecting cover one and connecting cover two to perform road surface leveling work on roads of different spans, resulting in high overall flexibility and a wider range of applications.

[0020] 2. In this invention, the motor drives the transmission wheels 1 and 2 inside the connecting cover 1 and connecting cover 2 to rotate, thereby driving the transmission belt to move at the bottom of the connecting cover 1 and connecting cover 2. This causes the entire housing to slide left and right on the connecting cover 1 and connecting cover 2. The leveling roller installed at the bottom of the housing contacts the toothed plate 1 while moving, pushing the substrate on the road surface to one side, making the road surface smoother. At the same time, the pressing block rotates after contacting the toothed plate 2 and presses against the road surface. When moving left and right, it completes further smoothing of the road surface, improving the overall smoothness of the road surface. A laser profiler is installed between the leveling roller and the pressing block to monitor the state of the road surface after smoothing in real time. The road substrate is discharged to the road surface depressions by controlling the flow control pipe on the storage cylinder. Combined with the smoothing of the pressing roller, the road surface is repaired at specific points, improving the overall smoothness of the road surface. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7 The present invention provides a technical solution:

[0031] Example 1:

[0032] For leveling construction surfaces, the process typically involves manually shoveling the mortar after it's poured onto the road surface, followed by using a road trowel for overall smoothing. Based on this, such as... Figure 1 As shown, the entire connecting cover 10 and connecting cover 21 form a base beam spanning the road surface. At the same time, a sliding mechanism 22 is installed on the connecting cover 10 and connecting cover 21. A buffer wheel 29 is provided at the bottom of the housing 221 on the sliding mechanism 22. Meanwhile, a transmission wheel 25 and a transmission wheel 26 are movably connected inside the connecting cover 10 and connecting cover 21.

[0033] like Figure 7 As shown, transmission wheel 25 and transmission wheel 26 are located on the inner walls of connecting cover 11 and connecting cover 10, respectively. Meanwhile, one side of the housing 221 is located on the surface of the transmission belt 27 on transmission wheel 25 and transmission wheel 26. Transmission wheel 25 and transmission wheel 26 are connected to the motor 14 located at the top of the fixed sleeve 17, so that when the motor 14 rotates, it drives the transmission belt 27 to rotate, and the housing 221 slides left and right on the top of connecting cover 10 and connecting cover 11.

[0034] The structure located inside the shell 221 is as follows Figure 6 As shown, a storage cylinder 222 is installed on the inner wall of the entire housing 221. The storage cylinder 222 is used for filling part of the road surface grout. Due to the different road paving substrates, when laying and compacting some loose sand, a certain amount of sand needs to be stored in the storage cylinder 222 beforehand. A flow control pipe 223 is connected to the bottom of the storage cylinder 222 for quantitative discharge of sand. A leveling roller 225 is movably connected to the bottom inner wall of the housing 221. One side of the leveling roller 225 penetrates the housing 221 and contacts the road surface. A pressing block 226 is movably connected to the rear of the leveling roller 225. At the same time, gears are sleeved and connected to the entire leveling roller 225 and the pressing block 226 on the inner and outer walls of the housing 221, which are combined... Figure 2As shown, a toothed plate 23 is fixedly connected to one inner wall of the entire connecting cover 10, and a toothed plate 24 is fixedly connected to one inner wall of the connecting cover 11. The toothed plate 23 and the toothed plate 24 are slidably connected. At the same time, through grooves 28 are opened on the inner walls of the corresponding connecting cover 10 and connecting cover 11. When it is necessary to adjust the combined width of the connecting cover 10 and connecting cover 11 later, the excess toothed plate 23 and toothed plate 24 can be discharged from the through grooves 28. The toothed plate 23 is connected to the gear on the top of the pressing block 226 on one side. The geared plate 24 meshes with the top gear of the leveling roller 225. When the transmission belt 27 pulls the housing 221 to move between the connecting cover 10 and the connecting cover 21, the leveling roller 225 and the pressing block 226 begin to rotate under the limiting position of the geared plate 23 and the geared plate 24. While the leveling roller 225 moves left and right, it begins to move forward at a fixed point through the movable bracket 1, thus leveling the road surface while rotating. The leveled road surface is then quickly smoothed by the pressing block 226 behind, thereby improving the overall flatness of the road surface. The leveling operation is suitable for concrete pavements. Since the leveling roller 225 and pressing block 226 are located approximately 10mm below the bottom of the concrete pavement, and the concrete has a high density, the leveling roller 225 continuously pushes excess material to one side as it rotates forward, thus minimizing pavement depressions during leveling. However, when leveling loose gravel pavements, indentation during pressing is more likely. Therefore, the laser profiler 224 located at the bottom of the housing 221 needs to be activated to level the pavement smoothed by the leveling roller 225. The laser profiler 224 is based on a laser rangefinder. The laser rangefinder is fixed on the housing 221. During the test, the laser rangefinder always monitors the height from the road surface. When a road surface depression occurs, it is marked in time, and the entire movable support 1 is controlled to stop moving forward. At the same time, the base material in the storage cylinder 222 falls to the corresponding road surface depression through the flow control pipe 223, and is smoothed by the cyclic squeezing of the pressing block 226, completing the repair of the fixed position during the road surface smoothing process and improving the overall smoothness of the road surface.

[0035] Example 2:

[0036] For common road leveling equipment, the lateral span is relatively fixed, which requires adjusting the equipment model when leveling roads of different widths, making the process quite cumbersome. Therefore, the entire connecting cover 10 and connecting cover 21 are slidably connected, with connecting cover 10 located inside connecting cover 21. To improve the overall stability of the connection between connecting cover 10 and connecting cover 21, one side of connecting cover 10 is fixed with a reinforcing rib 16 by bolts, while one side of connecting cover 21 is fixed with a fixing sleeve 17 by bolts. The fixing sleeve 17 has a limit groove 21. Figure 5As shown, the entire limiting groove 21 is used to limit the fixing cylinder 18 on one side of the sleeve 19 on the reinforcing rib 16, so that the fixing cylinder 18 cannot slide freely in the limiting groove 21. However, when the operator presses the fixing cylinder 18 into the sleeve 19, the connecting cover 10 and the connecting cover 21 can be pushed to adjust the overall width of the combined sleeve. After the width of the combined sleeve is adjusted, one end of the fixing cylinder 18 is released. At this time, the spring 20 pushes the fixing cylinder 18 out again and abuts against the limiting groove 21.

[0037] Meanwhile, for the height adjustment of the entire connecting cover 10 and connecting cover 2 11 combined housing, a rotating sleeve 13 is movably connected to the fixed cover 12 located on the connecting cover 10 and connecting cover 2 11, and a placement plate 2 is fixed on the rotating sleeve 13 by bolts, and the placement plate 2 is slidably connected to the movable bracket 1.

[0038] An adjusting box 3 is bolted to the entire movable support 1, and a rotating arm 5 is rotatably connected to one side of the adjusting box 3. The rotating arm 5 can also slide with the adjusting box 3. Normally, the toothed rod 6 connected to the rotating arm 5 abuts against the toothed post 4 on the inner wall of the adjusting box 3. When the operator pushes the movable support 1, pushing the rotating arm 5 forward causes the rotating arm 5 to... Figure 4 As shown, the entire rotating arm 5 is to be rotated counterclockwise by the operator. The counterclockwise rotation of the rack 6 will push the toothed column 4 down. However, since the inner wall of the entire regulating box 3 is also connected to the limit rod 7, and the limit tooth block 8 is fixed at one end of the limit rod 7, the bottom of the limit tooth block 8 is inclined and the top is right angled. The teeth of the entire toothed column 4 correspond to the limit tooth block 8. Therefore, when the toothed column 4 moves downward, the right angled teeth on the toothed column 4 contact the right angled teeth on the limit tooth block 8, causing the toothed column 4 to be unable to move downward on the inner wall of the regulating box 3. Therefore, the operator can push the entire movable bracket 1 forward normally.

[0039] When the operator rotates the rotating arm 5 downwards, the rotating arm 5 begins to drive the toothed column 4 upwards. At this time, the inclined teeth on the toothed column 4 contact the inclined teeth on the limit tooth block 8, causing the limit tooth block 8 to vibrate continuously as the toothed column 4 moves upwards. When the rotating arm 5 pushes upwards, the toothed rod 6 abuts against the toothed column 4, preventing the rotating arm 5 from rotating. At this point, the rotating arm 5 needs to be pulled away from the teeth on the toothed column 4, and then the rotating arm 5 can rotate normally. Through the above operations, the entire toothed column 4 can be made to move continuously upwards. One end of the toothed column 4 passes through the adjusting box 3 and connects to the placement plate 2, thereby driving the fixing sleeve 17 on the placement plate 2 to rise, ultimately achieving... The overall height of the connecting cover 10 and connecting cover 21 can be adjusted. When it is necessary to lower the height of the entire placement plate 2, press one end of the limiting rod 7 located on one side of the adjustment box 3. This will cause the limiting rod 7 to rotate and compress the spring 9. During the rotation of the limiting rod 7, the limiting tooth block 8 will disengage from the toothed post 4. The toothed post will automatically slide down under the gravity of the placement plate 2. The bottom of the connecting cover 10 and connecting cover 21 is movably connected to the roller 15, which moves in conjunction with the entire movable bracket 1. By adjusting the height and width of the combined cover of the connecting cover 10 and connecting cover 21, the application range of the entire construction ground leveling equipment is widened, and the overall operation is more flexible.

[0040] Working principle of the invention:

[0041] While the operators on both sides of the movable support 1 push the rotating arm 5, the rotating arm 5 rotates downward. At the same time, while pulling back the rotating arm 5, it is lifted upward, so that the toothed column 4 in the adjustment box 3 drives the placement plate 2 to move upward. Correspondingly, the fixed cover 12 connected to one side of the placement plate 2 drives the connecting cover one 10 and the connecting cover two 11 to rise simultaneously. Then, the bottom rollers 15 of the entire connecting cover one 10 and the connecting cover two 11 are set on both sides of the ground to be leveled, so that the leveling roller 225 and the pressing block 226 are 10mm below the ground.

[0042] At the same time, press down on the two fixed cylinders 18 located on the fixed sleeve 17, and at the same time, the operators on both sides push the connecting cover 10 and the connecting cover 2 11 inward so that one side of the roller 15 is aligned with the edge of the road surface.

[0043] The bottom transmission device of the activated support 1 drives the connecting cover 10 and the connecting cover 21 to move a certain distance. At the same time, the motor 14 drives the transmission wheel 1 25 and the transmission wheel 26 inside the connecting cover 10 and the connecting cover 21 to rotate. This causes the leveling roller 225 and the pressing block 226 installed on the transmission belt 27 to start moving left and right on the connecting cover 10 and the connecting cover 21 with the housing 221. As the leveling roller 225 and the pressing block 226 move, they come into contact with the toothed plate 1 23 and the toothed plate 24. The rotating leveling roller 225 starts to rotate as it moves, pushing the concrete paved on the road surface to one side. At the same time, the pressing block 226 smooths the road surface.

[0044] When the entire housing 221 moves at the top of the connecting cover 10 and the connecting cover 21, the laser profiler 224 feeds back the road surface flatness information measured by the laser profiler 224 to the control box on the movable support 1. The control signal generated by the control box realizes the fixed-point material discharge operation of the flow control tube 223, and finally the material is smoothed by the pressing block 226.

At the same time, press down on the two fixed cylinders (18) located on the fixed sleeve (17), and at the same time, the operators on both sides push the connecting cover one (10) and the connecting cover two (11) inward so that one side of the roller (15) is aligned with the edge of the road surface. The moving, rotating, and pressing mechanism activates the bottom transmission device of the movable bracket (1), which drives the connecting cover one (10) and connecting cover two (11) to move a certain distance. At the same time, the motor (14) drives the transmission wheel one (25) and transmission wheel two (26) inside the connecting cover one (10) and connecting cover two (11) to rotate, so that the leveling roller (225) and pressing block (226) installed on the transmission belt (27) begin to move left and right on the connecting cover one (10) and connecting cover two (11) along with the housing (221). While the leveling roller (225) and pressing block (226) are moving, they come into contact with toothed plate one (23) and toothed plate two (24). The rotating leveling roller (225) begins to rotate while moving, and pushes the concrete paved on the road to one side. At the same time, the pressing block (226) smooths the road surface. When the entire shell (221) moves on top of the connecting cover one (10) and the connecting cover two (11), the laser profiler (224) feeds back the road surface flatness information measured by the laser profiler (224) to the control box on the movable support (1). The control signal generated by the control box realizes the fixed-point discharge operation of the flow control tube (223), and finally smooths it out by pressing block (226).
