Description

Technical Field

[0001] This invention belongs to the field of floor leveling technology, and in particular relates to a walking device for a special leveling equipment for double-layer bidirectional reinforced concrete floor construction. Background Technology

[0002] In the actual construction of large-area floor leveling, controlling the flatness of the floor is of paramount importance. The degree of flatness control will affect the construction quality of the next process. If it cannot be completed in one go, it will greatly increase construction costs and cause delays in the construction period. Therefore, for large-area floor leveling construction, a combination of manual labor and heavy machinery is often used to control the flatness of the floor.

[0003] The current conventional method for leveling concrete in a single operation involves: before pouring concrete, the laser screed machine must be debugged, the laser emitter set up and leveled, and the leveling head adjusted according to the emitted signal. Piles of concrete are then roughly leveled manually, and the laser screed machine completes the vibration, compaction, and leveling in one operation. Because large machinery like laser screed machines cannot be used above double-layered, bidirectional reinforcing steel, steel supports are required to support the equipment. This equipment must move on the supports without contacting the reinforcing steel frame. The steel supports need to be moved multiple times depending on the use of the large machinery, significantly impacting the construction schedule.

[0004] Traditional methods are cumbersome, requiring repeated disassembly and reassembly of the rails (steel masts). After each pour, a leveling device controlled by the telescopic cantilever of a large apparatus is used for leveling. After leveling an area, the rails (steel masts) are moved to the rear for reconnection, allowing the large apparatus to retreat step by step for further leveling operations.

[0005] For example, the invention patent with publication number CN113107175A discloses a method for controlling the flatness of large-area floors. This method involves creating process tracks that are easy to handle manually, allowing a concrete laser screed machine to travel on these tracks for paving and leveling. However, process tracks for large mobile equipment are heavy, difficult to move, and can delay the construction period, thus affecting construction efficiency.

[0006] For example, the invention patent with publication number CN118997424A discloses a method for one-time leveling of a large-area floor with double-layer bidirectional steel reinforcement. This method involves setting multiple rows of elevation control track assemblies above the lower subbase, and using a leveling machine to vibrate and level the surface by vibrating the sides of the elevation control tracks at both ends. However, when the concrete initially sets, the elevation control tracks need to be removed, and the grooves left by the removal of the tracks need to be manually filled with pre-reserved concrete. This process is cumbersome and damages the overall pouring quality of the concrete. Summary of the Invention

[0007] To address the technical problems existing in the background art, the present invention provides a walking device for a leveling equipment specifically designed for double-layer, two-way reinforced concrete floor construction.

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows: A walking device for a leveling equipment specifically designed for double-layer, two-way reinforced concrete floor construction includes: Several U-shaped support frames are laid flat on the bottom pad layer. The U-shaped support frames are arranged in two sets at intervals along the pouring direction. Double-layer bidirectional steel bars are laid on the bottom side pad layer, and the U-shaped support frame extends to the upper side of the double-layer bidirectional steel bars through the gaps in the double-layer bidirectional steel bars. A track assembly is slidably mounted on a U-shaped support frame. Two sets of track assemblies are provided, and the two sets of track assemblies are connected by a telescopic mechanism. A traveling device is provided on the track assembly. The traveling device has a telescopic arm, and a laser leveling instrument is installed at the end of the telescopic arm. The track assembly has a through groove inside along the casting direction. The walking device has wheels and a liftable support arm. A support plate is provided at the bottom end of the support arm. The width of the through groove is smaller than the width of the wheel, and the width of the support plate is smaller than the width of the through groove. The walking device travels on the track assembly via wheels, and the support plate can be selectively supported on the track assembly or on the U-shaped support frame on the bottom side of the track assembly. When the support plate is supported on the track assembly, the positions of the walking device and the track assembly are fixed, and the poured concrete is leveled using a laser leveling instrument. When the support plate is supported on the U-shaped support frame through the through groove, the position of the walking device is fixed, and the track assembly can be adjusted to move on its own using the telescopic mechanism.

[0009] Optionally, the support arm is arranged around the walking device and located outside the wheel, with the wheel and support arm on the same side located on the same axis.

[0010] Optionally, the track assembly includes a central crossbar and tracks connected to both sides of several central crossbars, the tracks including a rectangular inner tube, a rectangular outer tube, and a rectangular support tube; The rectangular inner tubes are arranged in two sections at a fixed distance. The two rectangular inner tubes are connected by several rectangular support tubes, and gaps are left between adjacent rectangular support tubes to form anti-slip grooves. A rectangular outer tube is provided on the outer side of the rectangular inner tube, and the two sides of the several intermediate crossbars are respectively connected to a rectangular outer tube; the bottom side of the rectangular outer tube extends a fixed distance relative to the bottom side of the rectangular inner tube to form a sliding groove, and the track is slidably set on the U-shaped support frame through the sliding groove.

[0011] Optionally, a fixing plate is provided on several of the intermediate crossbars, and a hinge seat is provided on one side of the fixing plate; the telescopic mechanism is a hydraulic cylinder, the cylinder body end of the hydraulic cylinder is connected to the hinge seat of one of the track components, and the telescopic end of the hydraulic cylinder is connected to the hinge seat of another track component.

[0012] Optionally, the interior of several of the rectangular support tubes is cut to form through grooves, and rectangular square tubes are provided on the inner wall of the through grooves.

[0013] Optionally, along the length of the track, there are two rectangular tubes and two through slots symmetrically arranged.

[0014] Optionally, guide covers are provided on both sides of one of the track components, and the guide covers are slidably disposed against the side walls of the other track component.

[0015] Optionally, when the support plate is supported on the track assembly for leveling, the two track assemblies are closely aligned with each other, the support arms on both sides of the walking device are supported on the two track assemblies, and the support arms are supported in the track area between the two through slots of the same track assembly.

[0016] Optionally, the support plate is configured as a rectangular block, and the length of the support plate is half the length of the through groove.

[0017] Optionally, the walking device of the double-layer bidirectional reinforced concrete floor construction special leveling equipment also includes a photoelectric sensor for detecting the position of the walking device and the track assembly. The photoelectric sensor includes a transmitter and a receiver. The two sides of the support plate are symmetrically provided with stiffening plates, and the stiffening plates are respectively provided with transmitters. The inner wall of the rectangular tube is provided with a groove and a receiver is installed. The receiver has two mutually perpendicular first receiving ends and second receiving ends. An installation plate is inclinedly provided on the outer wall of the fixed end of the support arm, and a reflector is inclinedly installed on the installation plate; When the support plate is located in the through slot and supported on the U-shaped support frame, the horizontal beam emitted by the transmitter can be received by the first receiving end; When the wheel is supported on the track assembly and the support arm retracts to bring the transmitter and reflector to the same height, the horizontal beam emitted by the transmitter can be reflected by the reflector into a vertical beam that is received by the second receiver.

[0018] The present invention has the following advantages and beneficial effects: By designing self-propelled track components, the entire walking device is stably fixed on the track components during the leveling of poured concrete using a laser leveling instrument. When the position of the track components needs to be adjusted, the support plate of the walking device is supported on the U-shaped support frame through a through groove, avoiding the track components, thus fixing the position of the walking device. The self-propelled adjustment of the track components is achieved using a telescopic mechanism. This structure requires only a fixed number of track components to achieve convenient self-propelled adjustment of the track components, making operation simple and convenient. The track components only need to be supported on a certain number of U-shaped support frames for sliding adjustment, eliminating the need for repeated disassembly and assembly of a large number of tracks as in traditional methods, significantly improving construction efficiency.

[0019] By designing photoelectric sensors to detect the position of the walking device and track components, precise position adjustment is achieved. Transmitters positioned on both sides, along with a receiver installed at the same location, are used. Two mutually perpendicular receiving ends are integrated into the receiver. The raising and lowering of the lifting arm allows for the emission and reception of light beams from the transmitters in different directions, thus enabling precise detection of the track components and the walking device's position. This design avoids the obstruction of the support plate in both the horizontal and vertical directions, achieving accurate position detection. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] Example like Figures 1 to 16 As shown, a walking device for a leveling equipment for double-layer bidirectional reinforced concrete floor construction includes: a U-shaped support frame 2, double-layer bidirectional reinforcing bars 11, a track assembly 3, a walking device 4, and a laser leveling instrument 6.

[0025] like Figures 10-12 As shown, before pouring the concrete floor, a bottom layer 1, or base layer, is first leveled and installed. Several U-shaped support frames 2 are then placed flat on the bottom layer 1. Two sets of U-shaped support frames 2 are spaced apart and arranged along the pouring direction to support the movement of the track assembly 3. The U-shaped support frames 2 are made of lightweight aluminum alloy, making them easy to handle and eliminating the need to transport the track assembly 3 as a whole. The U-shaped support frames 2 are spaced apart and do not need to be placed close together; therefore, only a small number of U-shaped support frames 2 are needed to support the movement of the track assembly 3.

[0026] like Figure 12 As shown, the U-shaped support frame 2 is reinforced and fixed inside by an H-shaped steel frame 21. The U-shaped support frames 2 on both sides of the H-shaped steel frame 21 are supported on the foundation. The U-shaped support frames 2 are laterally limited by double-layer bidirectional steel bars 11.

[0027] like Figures 10-12 As shown, double-layer bidirectional reinforcing bars 11 are laid on the bottom pad 1, and U-shaped support frame 2 extends through the gaps in the double-layer bidirectional reinforcing bars 11 to the upper side of the double-layer bidirectional reinforcing bars 11. The U-shaped support frame 2 and the double-layer bidirectional reinforcing bars 11 do not contact each other and do not affect each other, ensuring that the subsequent walking device 4 and track assembly 3 can be supported on the U-shaped support frame 2, avoiding any impact on the double-layer bidirectional reinforcing bars 11, and ensuring the quality of subsequent floor construction. During construction, the double-layer bidirectional reinforcing bars 11 are installed first, and then the U-shaped support frame 2 is laid.

[0028] like Figures 1 to 16As shown, the track assembly 3 is slidably mounted on the U-shaped support frame 2, allowing it to move and adjust its position on the U-shaped support frame 2. Two sets of track assemblies 3 are provided, connected by a telescopic mechanism, thus allowing adjustment of the distance between the two track assemblies 3. A traveling device 4 is installed on the track assembly 3. The traveling device 4 is a conventional engineering vehicle, including a vehicle body 41, and components such as a telescopic arm 45, wheels 44, and support arms 42. A laser leveling device 6 is installed at the end of the telescopic arm 45 for leveling large areas of concrete.

[0029] like Figures 1 to 16 As shown, the track assembly 3 has a through groove 331 inside along the casting direction. The walking device 4 has a wheel 44 and a liftable hydraulic support arm 42. The bottom end of the support arm 42 is provided with a support plate 43. The width of the through groove 331 is smaller than the width of the wheel 44, ensuring that the wheel 44 can walk stably on the track assembly 3 and will not fall into the through groove 331. The width of the support plate 43 is smaller than the width of the through groove 331, ensuring that the support plate 43 can pass down through the through groove 331 and be supported on the U-shaped support frame 2.

[0030] like Figures 1-9 As shown, the walking device 4 travels on the track assembly 3 via wheels 44, and the support plate 43 can be selectively supported on the track assembly 3 or on the U-shaped support frame 2 on the bottom side of the track assembly 3.

[0031] like Figure 7 As shown, when the support plate 43 is supported on the track assembly 3, the wheel 44 also contacts the track assembly 3. The positions of the walking device 4 and the track assembly 3 are fixed, and the poured concrete is leveled using the laser leveler 6.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, when the support plate 43 passes through the through groove 331 and is supported on the U-shaped support frame 2, the wheel 44 does not contact the track assembly 3, and the wheel 44 is essentially suspended in the air. The walking device 4 is supported on the U-shaped support frame 2 by the support plate 43, and its position is fixed. The track assembly 3 is in an unfixed state, and the self-moving adjustment position of the track assembly 3 is achieved by using the telescopic mechanism. This design eliminates the influence of the walking device 4 when adjusting the position of the track assembly 3, thus allowing for convenient adjustment of the position of the track assembly 3. When adjusting the position of the track assembly 3, the U-shaped support frame 2 can be stably limited without slippage. This is because, in addition to its bottom support on the foundation surface, the U-shaped support frame 2 is limited by double-layer bidirectional steel bars 11 on all four sides. Therefore, the track assembly 3 can be precisely and stably guided, and the force generated when adjusting the track assembly 3 will not affect the double-layer bidirectional steel bars 11.

[0033] like Figures 1 to 16As shown, the support arms 42 are arranged around the walking device 4 and located outside the wheels 44. There are four support arms 42 and four wheels 44. The wheels 44 and support arms 42 on the same side are located on the same axis. This design allows the through slot 331 to be opened in the middle of the track assembly 3, so that the wheels 44 can travel in the middle of the track assembly 3 and will not fall off the through slot 331. The support arms 42 can pass through the through slot 331 and be supported on the U-shaped support frame 2 on the bottom side of the track assembly 3.

[0034] like Figure 8 , Figure 9 , Figures 13-16 As shown, the track assembly 3 includes a central crossbar 35 and a track connected to both sides of several central crossbars 35. The track includes a rectangular inner tube 31, a rectangular outer tube 34, and rectangular support tubes 32. Two rectangular inner tubes 31 are arranged at a fixed distance from each other. The two rectangular inner tubes 31 are connected by several rectangular support tubes 32. A gap is left between adjacent rectangular support tubes 32 to form an anti-slip groove, which facilitates the stable movement of the wheels 44.

[0035] like Figure 8 , Figure 9 , Figures 13-16 As shown, a rectangular outer tube 34 is provided on the outer side of the rectangular inner tube 31, and the two sides of the several intermediate crossbars 35 are respectively connected to a rectangular outer tube 34. The bottom side of the rectangular outer tube 34 extends a fixed distance relative to the bottom side of the rectangular inner tube 31 to form a sliding groove 341. The track is slidably mounted on the U-shaped support frame 2 through the sliding groove 341 to achieve limited sliding.

[0036] like Figures 13-16 As shown, a fixing plate 36 is provided on several intermediate crossbars 35, and a hinge seat 37 is provided on one side of the fixing plate 36; the telescopic mechanism is a hydraulic cylinder 38, the cylinder end of the hydraulic cylinder 38 is connected to the hinge seat 37 of one of the track components 3, and the telescopic end 39 of the hydraulic cylinder 38 is connected to the hinge seat 37 of the other track component 3. The movement of the two track components 3 on the U-shaped support frame 2 is controlled by the telescopic movement of the hydraulic cylinder 38.

[0037] like Figures 13-16 As shown, the interior of several rectangular support tubes 32 is cut to form through grooves 331, and rectangular square tubes 33 are provided on the inner wall of the through grooves 331 to further enhance the strength of the overall structure.

[0038] like Figures 1 to 16 As shown, two rectangular tubes 33 and two through slots 331 are symmetrically arranged along the length of the track. While slotting, the rigidity of the overall structure is ensured as much as possible. At the same time, with slots on both sides, there is no need to determine the installation direction, and it can be directly installed on the U-shaped support frame 2.

[0039] like Figures 1 to 16 As shown, guide covers 5 are respectively provided on both sides of one of the track components 3. The guide covers 5 are slidably arranged close to the side walls of the other track component 3. The guide covers 5 realize the sliding limit of the two track components 3. At the same time, when the walking device 4 transitions on the two track components 3, they can reliably limit each other to avoid the phenomenon of lifting at the docking position, and ensure that the track components 3 can stably supply the walking device 4 to move.

[0040] like Figure 7 As shown, when the support plate 43 is leveled on the track assembly 3, the two track assemblies 3 are closely aligned with each other, and the support arms 42 on both sides of the walking device 4 are supported on the two track assemblies 3, with the support arms 42 supporting the track area between the two through slots 331 of the same track assembly 3. This design allows the support point of the walking device 4 to be located in the middle of the two track assemblies 3, achieving stable support.

[0041] Furthermore, the support plate 43 is configured as a rectangular block, and its length is half the length of the through groove 331. By optimizing the dimensional relationship between the through groove 331 and the support plate 43, each track assembly 3 moves a distance equal to half the length of the through groove 331 each time the distance is adjusted, which can achieve safe and stable movement over small distances and facilitate positioning.

[0042] like Figures 17-19 As shown, the walking device of the double-layer bidirectional reinforced concrete floor construction special leveling equipment of the present invention also includes photoelectric sensors for detecting the position of the walking device 4 and the track assembly 3.

[0043] like Figures 17-19 As shown, the photoelectric sensor includes a transmitter 7 and a receiver 8. Photoelectric sensors are mounted on both track assemblies 3. Ribs 431 are symmetrically arranged on both sides of the support plate 43 for reinforcement, and transmitters 7 are mounted on the ribs 431 respectively. A groove is formed in the inner wall of one side of the rectangular tube 33, and the receiver 8 is installed therein. The receiver 8 is located inside the groove to avoid collision with the bottom and sides of the support plate 43. The receiver 8 has two mutually perpendicular receiving ends 81 and 82.

[0044] like Figures 17-19 As shown, an inclined mounting plate 9 is provided on the outer wall of the fixed end of the support arm 42, and a reflector 91 is inclinedly mounted on the mounting plate 9 to reflect the light beam emitted by the emitter 7.

[0045] like Figure 17 and Figure 18As shown, when the support plate 43 is located within the through groove 331 and supported on the U-shaped support frame 2, the position of the walking device 4 is fixed, while the position of the track assembly 3 is adjustable. The horizontal beam X1 emitted by the left transmitter 7 can be received by the first receiver 81. With this design, when the track assembly 3 moves, the distance between the inner rectangular tube 33 and the support plate 43 changes. This change in distance can be detected by a photoelectric sensor, thereby accurately determining the position change of the track assembly 3.

[0046] like Figure 19 As shown, when the wheel 44 is supported on the track assembly 3, the position of the track assembly 3 is fixed. The walking device 4 moves on the track assembly 3. When the control support arm 42 retracts so that the transmitter 7 and the reflector 91 are at the same height, the horizontal beam emitted by the right transmitter 7 can be reflected by the reflector 91 into a vertical beam X2, which is received by the second receiving end 82. This accurately detects the position of the support plate 43 when the walking device 4 moves, ensuring that the support plate 43 can reach the center line L1 of the track assembly 3 and descend for stable support, so as to provide leveling operation for the subsequent laser leveling instrument 6.

[0047] like Figure 2 As shown, at this time, the walking device 4 is supported on the U-shaped support frame 2, and the two track components 3 are connected to each other and are tightly attached to the left inner wall of the rectangular square tube 33 of the two track components 3. The position of the track components 3 can be adjusted by moving them to the left.

[0048] exist Figure 2 In the indicated state, hydraulic cylinder 38 extends, driving the left track assembly 3 to move to the left, away from the right track assembly, until the right inner wall of the rectangular tube 33 of the left track assembly 3 abuts against the support plate 43 (as shown). Figure 4 (As shown).

[0049] exist Figure 4 In the indicated state, hydraulic cylinder 38 retracts, driving the right track assembly 3 to move to the left, close to the left track assembly, until the right inner wall of the rectangular tube 33 of the right track assembly 3 abuts against the support plate 43 (as shown). Figure 5 (As shown). In this case, the two track components 3 complete one stroke of displacement.

[0050] If further displacement is required, simply lift the support plate 43 slightly to maintain a stress-free state, and control the traveling device to move to the left to reset. Figure 2 To achieve the desired state, simply repeat the above steps.

[0051] Once the position of track assembly 3 is adjusted, simply control the support plate 43 to lift it up and keep it suspended (e.g. Figure 6As shown), control the walking device to move to the left until it reaches the center position of track assembly 3, and then descend to provide support (as shown). Figure 7 As shown in the figure, a laser leveling instrument can be used for leveling operations.

[0052] like Figures 20-22 As shown, in order to simplify the structure, reduce the number of photoelectric sensors, and achieve linkage control to accurately identify the position of the walking device 4 and the track assembly 3, a self-rotating mechanism is set on the bottom side of the support arm 42. By utilizing the extension and retraction process of the support arm 42, the height and angle of the photoelectric sensor are adjusted by rotating the self-rotating mechanism.

[0053] like Figures 20-22 As shown, the self-rotating mechanism includes a top rotating cylinder 421 and a bottom rotating cylinder 432. The top rotating cylinder 421 is fixedly mounted on the bottom wall of the fixed end of the support arm 42, and the bottom rotating cylinder 432 is rotatably mounted on the upper end face of the support plate 43. Both the top rotating cylinder 421 and the bottom rotating cylinder 432 are sleeved on the outer side of the telescopic end of the support arm 42, with the top rotating cylinder 421 located inside the bottom rotating cylinder 432. A spiral groove 422 is formed on the outer wall of the top rotating cylinder 421, with an angle difference of 180 degrees between the bottom and top ends of the spiral groove 422. A guide roller 433 is installed at the upper end of the bottom rotating cylinder 432, extending into the inner side of the bottom rotating cylinder 432 and engaging in the spiral groove 422. A photoelectric sensor transmitter 7 is installed on one side of the bottom rotating cylinder 432. When the support arm 42 telescopically moves, it links the support plate 43 and the bottom rotating cylinder 432 to rise and fall, thereby linking the bottom rotating cylinder 432 to rotate, and thus adjusting the height and angle of the transmitter 7.

[0054] like Figure 21 As shown, when the support arm 42 extends out and the support plate 43 is located in the through groove 331 and supported on the U-shaped support frame 2, the position of the walking device 4 is fixed, while the position of the track assembly 3 can be adjusted. The horizontal beam X1 emitted by the transmitter 7 can be received by the first receiver 81.

[0055] like Figure 22 As shown, at this time, the support arm 42 retracts, causing the transmitter 7 to rise and rotate 180 degrees, ensuring that the transmitter 7 emits a beam of light towards the reflector 91. At this time, the wheel 44 is supported on the track assembly 3. The positions of the walking device 4 and the track assembly 3 are fixed, and the retraction of the support arm 42 makes the transmitter 7 and the reflector 91 at the same height. The horizontal beam of light emitted by the transmitter 7 can be reflected by the reflector 91 into a vertical beam X2, which is received by the second receiving end 82. This accurately detects the positioning of the support plate 43, ensuring that the support plate 43 can reach the center line L1 of the track assembly 3 and descend for stable support, so as to provide leveling operation for the subsequent laser leveling instrument 6.

[0056] This structural design, through a self-rotating mechanism, utilizes the telescopic movement of the support arm 42 (when extended, it supports the walking device 4, i.e., adjusts the position of the track assembly 3; when retracted, it adjusts the position of the walking device), to adjust the height and angle of the transmitter 7 of the same photoelectric sensor, thereby adapting to detection in different directions and cleverly achieving accurate position detection of the walking device and track assembly in different directions.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
