[0001] This invention belongs to the field of concrete construction technology, specifically relating to a seamless construction device and process for large-area ultra-flat concrete floors. Background Technology

[0002] In the field of concrete construction technology, ultra-flat ground construction has high requirements for construction efficiency and construction quality. The core working method of the widely used laser screed machine is to directly set a telescopic structure on the vehicle body, and through this structure, the screed plate is driven to perform leveling operations on the concrete surface.

[0003] However, the telescopic structure of existing laser screed machines has obvious design limitations, and the range that it can extend is relatively small. This results in a limited construction coverage area for a single machine. When facing the construction needs of large-area ultra-flat concrete floors, it is necessary to move the equipment frequently and work in sections. This not only greatly reduces construction efficiency, but also easily causes flatness deviations at the joints of sections, affecting the overall construction quality of the ground.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1; refer to Figure 1 and Figure 2 The structure shown is a seamless construction device for large-area ultra-flat concrete floors, comprising a mobile vehicle body 1 and a support frame 2. Multiple sets of drive components 6 are mounted on the bottom surface of the support frame 2, and the drive ends of the drive components 6 are connected to a base plate. An installation plate 3 is rotatably connected to the mobile vehicle body 1, and a storage mechanism 4 is mounted on the installation plate 3. The support frame 2 is connected to the drive end of the storage mechanism 4. A drive component 5 is provided on the support frame 2, and the drive end of the drive component 5 is connected to a retractable and extendable working support 6. The working support 6 is equipped with... There are multiple sets of broken rails. After the storage mechanism 4 drives the support frame 2 to be parallel to the ground, the drive component 6 drives the base plate to abut against the ground. The drive component 5 drives the working bracket 6 to unfold laterally, so that the multiple sets of broken rails are connected end to end to form a complete slide rail 7. A flat plate 10 is slidably set on a set of broken rails close to the moving vehicle body 1. A displacement mechanism is connected to the support frame 2. The displacement mechanism first drives the flat plate 10 to stick to the concrete plane, and then drives the flat plate 10 to slide along the surface of the slide rail 7 to scrape the concrete flat plate 10. The working support 6 is provided with a connecting mechanism at the end away from the mobile vehicle body 1, and working supports 6 with the same structure are connected through the connecting mechanism.

[0020] The construction device in this embodiment can be used alone or by connecting two construction devices together. Due to the support frame 2, the construction device of the present invention is more stable when used alone compared with the existing laser leveling machine. The two sets of construction devices after docking are not only more stable, but also allow for a wider construction range.

[0021] In this embodiment, a drive motor can be installed on the mobile vehicle body 1 and cooperate with two sets of meshing gears to drive the mounting plate 3 to rotate. Specifically, one set of gears is coaxially connected to the mounting plate 3, and the drive motor drives the other set of gears to rotate, thereby driving the gear coaxially connected to the mounting plate 3 to rotate, thereby further driving the mounting plate 3 to rotate. The drive motor is a stepper motor, servo motor, etc.

[0022] In the initial state, such as Figure 12 As shown, the working support 6 is retracted and tilted. In actual use, the mobile vehicle 1 is driven to the construction position, and then the storage mechanism 4 is activated to drive the support frame 2 and bring the working support 6 to a horizontal position (the specific state is as follows). Figure 1 (As shown), then start the drive unit six to drive the base plate to abut against the ground. At this time, the drive unit five can be started to drive the working bracket 6 to unfold, so that multiple sets of broken rails form a complete slide rail 7. Finally, start the displacement mechanism. The displacement mechanism first drives the whole plate 10 to stick to the concrete plane, and then drives the whole plate 10 to slide along the surface of the slide rail 7 to scrape the concrete. After the construction is completed, the construction device is restored to the initial state. If it is necessary to dock two construction devices, both sets of construction devices must be operated simultaneously until the working supports 6 of both sets of construction devices are deployed. Then, the ends of the two working supports 6 furthest from the moving vehicle 1 are connected by a connecting mechanism to complete the docking. The docking state is as follows: Figure 2 As shown.

[0023] refer to Figure 3 and Figure 4The structure shown is such that the working support 6 is symmetrically arranged. The working support 6 includes multiple sets of linearly arranged transmission components. Each set of transmission components includes an upper plate 61 and symmetrically arranged side plates 621 and 622. Parallel connecting rods 64 and 65 are rotatably connected to the surface of the upper plate 61. The ends of connecting rods 64 and 65 away from the upper plate 61 are rotatably connected to side plates 621 and 622, respectively. Side plates 621 and 622 of adjacent sets of transmission components are fixedly connected and merged to form a lower plate 62. The ends of connecting rods 64 and 65 on the upper plate 61 and lower plate 62, which are close to each other, are connected to meshing transmission gears 63. The side plate 621 of the transmission component closest to the moving vehicle body 1 is connected to the support frame 2. A stabilizing plate 16 is connected to the surface of each symmetrically arranged upper plate 61. Figure 5 As shown in the partial structure, the driving end of the driving component 5 is rotatably connected to a driving rod 15, and the two ends of the driving rod 15 are respectively connected to two sets of symmetrical connecting rods 64 closest to the moving vehicle body 1.

[0024] In actual use, the driving component 5 drives the two sets of working brackets 6 to unfold simultaneously through the driving rod 15. Specifically, the driving component 5 drives the connecting rod 64 closest to the moving vehicle body 1 to rotate, thereby driving the whole to unfold through the cooperation of the upper plate 61, side plate 621, side plate 622 and connecting rod 65. At this time, connecting rod 64 and connecting rod 65 are parallel to the horizontal plane.

[0025] refer to Figure 4 and Figure 6 The structure shown includes multiple sets of broken rails, each consisting of multiple sets of long rails 71 and multiple sets of short rails 72. In the retracted state, the long rails 71 are connected to the surfaces of connecting rod 64 and connecting rod 65, which are close to each other in each set of transmission components. One side of the short rails 72 is rotatably connected to the surface of the upper plate 61 in each set of transmission components. The surface of the upper plate 61 is rotatably connected to the driving component 13, and the driving end of the driving component 13 is rotatably connected to the short rails 72.

[0026] It should be noted that when the working support 6 is unfolded, it will drive the long rail 71 connected to the first connecting rod 64 and the second connecting rod 65 to move until the first connecting rod 64 and the second connecting rod 65 are parallel to the horizontal plane. At the same time, the long rail 71 is also parallel to the horizontal plane. Since the short rail 72 is set on the upper plate 61, when the working support 6 is in a horizontal state, whether it is retracted or unfolded, the short rail 72 is always in a horizontal state.

[0027] In actual use, when the working support 6 is unfolded, it will drive the long rail 71 to move to a horizontal state. At this time, the driving component 313 can be activated to drive the short rail 72 to rotate, so that the short rail 72 and the long rail 71 are on the same straight line. In this state, the slide rail 7 is complete.

[0028] refer to Figure 7 and Figure 8 The structure shown includes a connecting mechanism comprising a locking element 11 and a locked element 12, which are respectively connected to the surfaces of two sets of symmetrically arranged side plates 622 furthest from the moving vehicle body 1.

[0029] It should be noted that, since each set of construction devices has the same structure, when the two sets of construction devices are connected, the locking parts 11 and the locked parts 12 on the two sets of construction devices are connected to each other, thereby connecting the two sets of working supports 6.

[0030] Furthermore, the locking component 11 includes a first docking block 111 and a second driving component 112. Both the second driving component 112 and the first docking block 111 are fixedly connected to the surface of the second side plate 622. The driving end of the second driving component 112 is fixedly connected to a first inclined block 113. The surface of the first docking block 111 is provided with a docking groove 114.

[0031] Furthermore, the locked component 12 includes a second docking block 121, the surface of which is provided with a sliding groove 122. A straight rod 123 is fixedly connected to the surface of the second side plate 622. A straight block 124 is fixedly connected to the end of the straight rod 123 away from the second side plate 622. A sliding block 125 is slidably connected to the surface of the straight rod 123. One end of the sliding block 125 passes through the sliding groove 122. An inclined block 126 is connected to the end of the sliding block 125 away from the straight rod 123. A return spring 127 is sleeved on the outside of the straight rod 123. The two ends of the return spring 127 are respectively connected to the surfaces of the second side plate 622 and the sliding block 125.

[0032] In actual use, align the ends of the two sets of working supports 6. At this time, the inclined surface of inclined block 113 and the inclined surface of inclined block 2126 are on the same plane. Start the drive unit 212 to drive inclined block 113 to move closer to inclined block 2126. With the cooperation of the two inclined surfaces, inclined block 2126 moves to the side with the return spring 127 until inclined block 113 moves between inclined block 2126 and straight block 124 (at this time, inclined block 113 is located in the docking groove 114 and the sliding groove 122, and inclined block 113 and inclined block 2126 are locked together). Under the action of the return spring 127, inclined block 113 cannot return to its original position. At this time, the two sets of working supports 6 are connected together, and the concrete leveling operation can be performed.

[0033] refer to Figure 5 and Figure 9 The structure shown includes a lateral transmission assembly 8 and a vertical drive assembly 9. The lateral transmission assembly 8 is connected to the support frame 2, and a trolley 14 is fixedly connected to the drive end of the lateral transmission assembly 8. The flat plate 10 is fixedly connected to the drive end of the vertical drive assembly 9, and the vertical drive assembly 9 is mounted on the trolley 14. The lateral transmission component 8 is a scissor-type telescopic structure; The vertical drive assembly 9 includes a drive component 91 connected to the upper surface of the trolley 14. A worm gear 93 is rotatably connected to the upper surface of the trolley 14. A worm 92 is fixedly connected to the drive end of the drive component 91. The worm gear 93 and the worm 92 mesh. A screw 94 is threadedly connected to the inner wall of the worm gear 93. The lower end of the screw 94 passes through the trolley 14 and is fixedly connected to the flat plate 10. A telescopic rod 95 is fixedly connected to the surface of the flat plate 10. The upper end of the telescopic rod 95 is fixedly connected to the trolley 14.

[0034] Among them, the driving component 491 can be a stepper motor, servo motor, etc.

[0035] It should be noted that the telescopic rod 95 is designed to restrict the rotation of the screw 94, allowing the screw 94 to move only up and down.

[0036] In actual use, the drive component 91 drives the worm gear 92 to rotate, the worm gear 92 drives the worm wheel 93 to rotate, and the worm wheel 93 drives the screw 94 to move up and down, thereby driving the entire plate 10 to move up and down.

[0037] refer to Figure 10 and Figure 11 The structure shown is such that the storage mechanism 4 is symmetrically arranged. The storage mechanism 4 includes a drive member 41, a first rod 42, an outer support rod 43, an inner support rod 44, and a last rod 45. The drive end of the drive member 41 is rotatably connected to the surface of the first rod 42, and the end of the drive member 41 away from the drive end is rotatably connected to the mounting plate 3. Both the outer support rod 43 and the inner support rod 44 include a first adapter 431, a second adapter 432, a third adapter 433, and a main body 444. The first adapter 431, the second adapter 432, and the third adapter 433 are connected by the main body 444. The connection is as follows: two sets of adapter parts 432 are rotatably connected to each other; one end of the first rod 42 is rotatably connected to the adapter part 431 of the inner support rod 44; the other end of the first rod 42 is rotatably connected to the mounting plate 3; a fixing block 46 and a fixing block 47 are fixedly connected to the support frame 2; one end of the last rod 45 is rotatably connected to the adapter part 431 of the outer support rod 43; the other end of the last rod 45 is rotatably connected to the fixing block 47; the adapter part 433 of the inner support rod 44 is rotatably connected to the fixing block 46; and the adapter part 433 of the outer support rod 43 is rotatably connected to the mounting plate 3.

[0038] In actual use, the drive component 41 drives the first rod 42 to move, and with the cooperation of the outer support rod 43, the inner support rod 44 and the last rod 45, it drives the support frame 2 to move.

[0039] Furthermore, the end rod 45 includes two sets of mounting parts 451 and overlapping parts 452. The overlapping parts 452 are hook-shaped. The two sets of mounting parts 451 are respectively connected to the two ends of the overlapping parts 452. The two ends of the two sets of mounting parts 451 away from the overlapping parts 452 are respectively connected to the first adapter part 431 of the outer support rod 43 and the second fixing block 47.

[0040] In this embodiment, drive component 1 41, drive component 2 112, drive component 3 13, drive component 5, and drive component 6 are all electric push rods, cylinders, hydraulic cylinders, etc.

[0041] It should be noted that when the working support 6 is in a tilted state, the entire flat plate 10 can be overlapped in the hook-shaped overlap part 452.
