Description

Technical Field

[0001] This invention relates to the field of building construction and maintenance technology, and in particular to a device and method for the construction and maintenance of large-volume concrete raft foundations. Background Technology

[0002] A raft slab is a concrete slab used in foundation engineering. It is named for its floating nature on the soil, much like a raft. Due to the characteristics of large-volume concrete raft slabs—thick structure, large size, and high construction technical requirements—the construction of raft slabs presents significant challenges. Besides meeting design strength requirements, controlling the heat of hydration, preventing shrinkage cracks, temperature cracks, and internal capillary cracks to achieve the designed impermeability and non-shrinkage effect are key difficulties. Therefore, after concrete pouring, the heat of hydration accumulated inside the concrete is difficult to dissipate, and its internal temperature gradually rises. Since the concrete surface is in contact with the atmosphere, it dissipates heat more easily, necessitating surface curing. Traditional curing methods mainly involve manually spraying cooling water periodically to lower the temperature. This is time-consuming and labor-intensive, cannot achieve 24-hour continuous monitoring, and cannot be adjusted in real-time according to the ground's moisture level, resulting in significant waste during curing and a lack of precision and stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an improved large-volume concrete raft foundation construction and curing device and method to address the problems existing in the background art. This solves the problem that the traditional curing operation mainly relies on manual periodic spraying of cooling water on the surface to cool it down, which is not only time-consuming and labor-intensive, but also cannot achieve 24-hour uninterrupted monitoring of the construction. At the same time, it is impossible to adjust the spraying according to the dryness and humidity of the ground in real time, resulting in serious waste during the curing process and the curing method is not precise and stable enough.

[0004] The technical solution adopted by this invention to solve its technical problem is: a large-volume concrete raft foundation construction and maintenance device, comprising a horizontal infusion pipe fixedly installed on the construction surface of the large-volume concrete raft foundation, an elastic control valve installed on the upper end of the horizontal infusion pipe, a main frame, a four-way drive wheel set installed on the lower outer side of the main frame, a lifting mechanism, a detachable liquid storage container installed on the upper side of the main frame, and an electrically controlled water valve installed inside the main frame. Strip-shaped bottom spray nozzles cooperating with the electrically controlled water valve are installed on both sides of the lower surface of the main frame. A temperature and humidity sensor controller for detecting the temperature and humidity of the concrete raft foundation surface is fixedly mounted on the lower surface of the main frame. A rolling universal assembly for bottom monitoring is movably mounted below the temperature and humidity sensor controller on the lower surface of the main frame. A flip-mounted assembly frame for installing an infrared distance sensor is movably mounted on the outer side of the main frame.

[0005] The lower end of the outer side of the main frame is provided with front and rear transmission wheel grooves and left and right transmission wheel grooves corresponding to the four-way drive wheel assembly end. The lifting mechanism is installed inside the left and right transmission wheel grooves through a lateral assembly frame located inside the main frame.

[0006] The four-way drive wheel set includes a first drive wheel set that is movably assembled with the main frame by inserting it into the front and rear drive wheel grooves through a horizontal assembly shaft, a second adjustment wheel set that is movably assembled with the main frame by inserting it into the left and right drive wheel grooves through a horizontal control shaft, and a drive motor installed inside the main frame and connected to the first drive wheel set and the second adjustment wheel set respectively. The left and right drive wheel grooves are provided with longitudinally arranged strip-shaped lifting ports.

[0007] The lifting mechanism includes a lifting motor bolted to the inner walls of the left and right sides of the main frame, a horizontal adjusting screw axially driven on the rotating shafts on both sides of the lifting motor, two internal thread adjusting seats threaded onto the outside of the horizontal adjusting screw, a folding multi-link movably assembled between the two internal thread adjusting seats, and a bottom control seat assembled at the bottom end of the folding multi-link. The second adjusting wheel group is inserted into the bottom control seat through a transverse control shaft and is connected to the lifting mechanism for transmission.

[0008] The upper surface of the main frame is provided with an upper mounting hole for connecting the lower water outlet pipe of the detachable liquid storage container and the upper water inlet of the electric water valve. The upper end of the detachable liquid storage container has an upwardly protruding top liquid inlet seat, and a top permanent magnet that cooperates with the elastic control valve is fixedly mounted inside the upper surface of the top liquid inlet seat.

[0009] The outer side of the main frame is provided with a lateral storage groove for mounting the flip assembly frame. An LED status indicator light for displaying the monitoring status of the infrared distance sensor is fixedly mounted on the inner side of the lateral storage groove.

[0010] The drive shafts on both sides of the drive motor are connected to an internal drive shaft that meshes with the first drive wheel set. A bevel drive gear is axially fixed on the outer surface of the internal drive shaft. A bevel driven gear that meshes with the bevel drive gear is axially fixed on the inner end of the transverse control shaft.

[0011] The outer side of the main frame is equipped with solar panels for converting solar energy into electrical energy via a flip-adjustable frame.

[0012] A method for the construction and maintenance of large-volume concrete raft slabs is characterized by the following: During the construction and laying of the large-volume concrete raft slab, a horizontal infusion pipe for external water supply is installed at the edge of its surface. Then, the main frame is placed at the top corner of the construction surface. After the entire maintenance device is started, a drive motor drives the first drive wheel group to move, which in turn drives the main frame to move laterally. During this movement, a rolling universal assembly rolls at the bottom, transmitting ground information to the surface of a temperature and humidity sensor controller located at its upper end. When the surface dryness and temperature are too high, the temperature and humidity sensor controller activates the strip-shaped bottom spray nozzles located at the rear of the moving direction. During the movement, an infrared distance sensor located at the front of the moving direction monitors the ground in real time. The infrared distance sensor detects a sudden decrease in distance, indicating a protrusion ahead; it detects a sudden increase in distance, indicating a depression ahead. At this point, the infrared distance sensor shuts down the drive motor, controls the lifting mechanism to raise the second adjusting wheel set downwards, replacing the first drive wheel set to support the bottom of the main frame. The drive motor then engages with the second adjusting wheel set, moving the main frame forward one body length. The lifting mechanism then raises the second adjusting wheel set back to its original position, allowing the first drive wheel set to resume supporting the bottom of the main frame, causing it to move in the opposite direction. This process is repeated to complete the curing of the entire concrete raft foundation surface.

[0013] When the main frame moves to the side of the horizontal infusion tube, an elastic control valve is installed at the upper end of the horizontal infusion tube based on the pre-calculated storage capacity of the detachable liquid storage container and the drainage capacity of the electrically controlled water valve. When the main frame reaches the lower end of the elastic control valve, the top permanent magnet at the upper end of the detachable liquid storage container magnetically attracts the elastic control valve, and then automatically opens the connection between the elastic control valve and the horizontal infusion tube. After that, the lower outlet of the elastic control valve is inserted into the upper inlet of the detachable liquid storage container, and the horizontal infusion tube replenishes water to the inside of the detachable liquid storage container through the elastic control valve, thereby keeping the water level of the detachable liquid storage container full.

[0014] The beneficial effects of this invention are:

[0015] (1) The present invention provides a large-volume concrete raft construction curing device and method by using a main frame controlled by a four-way drive wheel group and a lifting mechanism to move in a serpentine manner on the construction surface of a large-volume concrete raft. The cooling water inside the detachable liquid storage container at the upper end of the electric water valve is evenly sprayed onto the construction surface, so that curing does not require manual operation, saving time and effort, and can be carried out continuously for 24 hours.

[0016] (2) The automated maintenance operation can not only complete automatic detection, but also automatically replenish the liquid inside the detachable liquid storage container, improve the operation endurance and greatly improve the maintenance efficiency.

[0017] (3) The surface state is transmitted to the temperature and humidity sensor controller by using a bottom monitoring rolling universal component, which can avoid the temperature and humidity sensor controller being affected by the external environment, improve the detection accuracy, and greatly reduce energy consumption.

[0018] (4) By opening a side storage groove for installing the flip assembly frame on the outer side of the main frame, and fixing an LED status indicator light for displaying the monitoring status of the infrared distance sensor on the inner side of the side storage groove, the monitoring interval of the maintenance device is adjustable, and the position of the maintenance device can be understood more intuitively in the case of insufficient light, so as to facilitate understanding of its working status.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Figure 1 , Figure 2 and Figure 3The device shown is a large-volume concrete raft foundation construction and maintenance device, including a horizontal infusion pipe 1 fixedly installed on the construction surface of the large-volume concrete raft foundation, an elastic control valve 2 installed on the upper end of the horizontal infusion pipe 1, a main frame 3, a four-way drive wheel set installed on the lower outer side of the main frame 3, a lifting mechanism, a detachable liquid storage container 4 installed on the upper side of the main frame 3, and an electrically controlled water valve 5 installed inside the main frame 3. Strip-shaped bottom spray nozzles 6 that cooperate with the electrically controlled water valves 5 are installed on both sides of the lower surface of the main frame 3. A temperature and humidity sensor controller 7 for detecting the temperature and humidity of the concrete raft foundation surface is fixedly installed on the lower surface of the main frame 3. A rolling universal assembly 8 for bottom monitoring is movably installed on the lower surface of the main frame 3 below the temperature and humidity sensor controller 7. A flip assembly frame 10 for installing an infrared distance sensor 9 is movably installed on the outer side of the main frame 3.

[0026] The temperature and humidity sensor controller 7 controls the opening and closing of the electric water valve 5, while the infrared distance sensor 9 is used to control the operation of the four-way drive wheel assembly and the lifting mechanism.

[0027] An existing electronic timer, not shown in the diagram, is installed inside the main frame 3. It is integrated into the control circuit within the main frame 3. The control circuit is existing technology, and both the control method and circuit connection are obtained through prior art procurement. The electronic timer automatically controls the operation of the entire device. The operation mode is as follows: Figure 1 The maintenance cycle is completed when the upper left corner moves to the lower right corner. Then, the main frame 3 is moved from the lower right corner to the upper left corner by an electronic timer for the second maintenance cycle. This cycle is repeated to maintain the entire construction area.

[0028] Among them, the electric water valve 5, temperature and humidity sensor controller 7, rolling universal assembly 8 and infrared distance sensor 9 are all existing technologies.

[0029] The lower end of the main frame 3 is located at the assembly end of the temperature and humidity sensor controller 7 and has a bottom monitoring hole. Then, the rolling universal assembly 8 includes a bottom assembly cylinder inserted into the bottom detection hole, an arc-shaped assembly frame axially fixed on both sides of the bottom of the bottom assembly cylinder, and a bottom monitoring wheel movably assembled between the two arc-shaped assembly frames.

[0030] To facilitate lateral assembly, the lower end of the outer side of the main frame 3 is provided with front and rear transmission wheel grooves 11 and left and right transmission wheel grooves 12 corresponding to the four-way drive wheel assembly end. The lifting mechanism is installed inside the left and right transmission wheel grooves 12 through the lateral assembly frame located inside the main frame 3.

[0031] To facilitate lateral transmission, the four-way drive wheel set includes a first drive wheel set 13 that is movably assembled with the main frame 3 by inserting it into the front and rear drive wheel grooves 11 via a transverse mounting shaft, a second adjusting wheel set 14 that is movably assembled with the main frame 3 by inserting it into the left and right drive wheel grooves 12 via a transverse control shaft, and a drive motor 15 that is installed inside the main frame 3 and is connected to the first drive wheel set 13 and the second adjusting wheel set 14 respectively. The left and right drive wheel grooves 12 are provided with longitudinally arranged strip-shaped lifting ports 16.

[0032] To facilitate lifting and adjusting, the lifting mechanism includes a lifting motor 17 bolted to the inner walls of the left and right sides of the main frame 3, a horizontal adjusting screw 18 axially driven on the rotating shafts on both sides of the lifting motor 17, two internal thread adjusting seats 19 threaded to the outside of the horizontal adjusting screw 18, a folding multi-link 20 movably assembled between the two internal thread adjusting seats 19, and a bottom control seat 21 assembled at the bottom end of the folding multi-link 20. The second adjusting wheel group 14 is inserted into the bottom control seat 21 through a transverse control shaft and is connected to the lifting mechanism for transmission.

[0033] The lifting motor 17 is existing technology. It drives the horizontal adjusting screw 18 to rotate, thereby driving the internal thread adjusting seats 19 on both sides to move along the horizontal adjusting screw 18. At this time, the internal thread adjusting seats 19 fold and flip with the folding multi-link 20, thereby driving the bottom control seat 21 to lift and adjust. Then, the bottom control seat 21 drives the second adjusting wheel group 14 to lift and adjust. The bottom control seat 21 uses the strip-shaped lifting port 16 to improve the lifting guidance and stability.

[0034] In order to connect the detachable liquid storage container 4 with the electric water valve 5, the upper surface of the main frame 3 is provided with an upper mounting hole 22 for connecting the lower water outlet pipe of the detachable liquid storage container 4 and the upper water inlet of the electric water valve 5. The upper end of the detachable liquid storage container 4 has an upwardly protruding top liquid inlet seat 23, and a top permanent magnet 24 that cooperates with the elastic control valve 2 is fixedly mounted inside the upper surface of the top liquid inlet seat 23.

[0035] To facilitate side storage, improve space utilization, and allow for real-time monitoring of the operating position and status of the main unit rack 3 at night, side storage grooves 25 for mounting the flip assembly frame 10 are provided on the outer side of the main unit rack 3. LED status indicator lights 26 for displaying the monitoring status of the infrared distance sensor 9 are fixedly mounted on the inner side of the side storage grooves 25.

[0036] The LED status indicator 26 is existing technology because only the infrared distance sensor 9 of the main frame 3 in the direction of travel will work. Therefore, only the LED status indicator 26 in the traveling position will be activated. The red and green colors respectively indicate the operating status of the infrared distance sensor 9. Red indicates that the distance is too close or too far and it is in the edge stop state; green indicates that the distance is appropriate and it is in the process state.

[0037] To coordinate with synchronous and switching drives, the drive shafts on both sides of the drive motor 15 are connected to an internal drive shaft 27 that meshes with the first drive wheel set 13. A bevel drive gear 28 is axially fixed on the outer surface of the internal drive shaft 27, and a bevel driven gear 29 that meshes with the bevel drive gear 28 is axially fixed on the inner end of the transverse control shaft.

[0038] The drive motor 15 always maintains a transmission relationship with the internal transmission shaft 27. That is, the first drive wheel set 13 always rotates with the drive motor 15. The second adjustment wheel set 14 only starts to rotate with the drive motor 15 when the bevel driven gear 29 meshes with the bevel drive gear 28. When the second adjustment wheel set 14 descends to replace the first drive wheel set 13 in supporting the main frame 3, the bevel drive gear 28 meshes with the bevel driven gear 29. When the second adjustment wheel set 14 rises and no longer supports the main frame 3, the bevel drive gear 28 and the bevel driven gear 29 disengage.

[0039] In order to automatically charge the existing lithium battery located inside the main frame 3 during idle time, a solar panel 31 for converting solar energy into electrical energy is mounted on the outer side of the main frame 3 via a flip adjustment frame 30.

[0040] The flip-adjustment frame 30 can be adjusted manually by flipping it, so that the existing solar panel 31 can be aligned with sunlight, improving the light energy conversion efficiency and reducing the requirements of the maintenance device on the power grid.

[0041] A method for curing large-volume concrete raft foundations involves installing horizontally placed infusion pipes 1 for external water supply at the edge of the raft foundation during construction. The main frame 3 is then positioned at the top corner of the construction surface. Once the entire curing device is activated, a drive motor 15 drives a first drive wheel assembly 13, which in turn moves the main frame 3 laterally. During this movement, a rolling universal assembly 8 rolls at the bottom, transmitting ground information to a temperature and humidity sensor controller 7 located above it. When the surface dryness or temperature is too high, the temperature and humidity sensor controller 7 activates the strip-shaped bottom spray nozzles 6 located at the rear of the direction of travel. During the movement, an infrared distance sensor 9 located at the front of the direction of travel monitors the ground in real time. When a sudden change in distance is detected... If the distance is short, it indicates a protrusion in front; if the detected distance suddenly increases, it indicates a depression in front. At this time, the infrared distance sensor 9 controls the drive motor 15 to shut down, controls the lifting mechanism to control the second adjusting wheel group 14 to lift downwards, and replaces the first drive wheel group 13 to support the bottom of the main frame 3. Then, the drive motor 15 engages with the second adjusting wheel group 14 to drive the main frame 3 forward by moving the main frame 3 one body length. Then, the lifting mechanism controls the second adjusting wheel group 14 to lift upwards and reset. At this time, the first drive wheel group 13 replaces the second adjusting wheel group 14 to support the bottom of the main frame 3 again, and drives the main frame 3 to move in the opposite direction. Then, the above operation is repeated to complete the curing operation of the entire concrete raft slab construction surface.

[0042] In order to automatically replenish the liquid inside the removable liquid storage container 4 and thus improve the maintenance endurance, when the main frame 3 moves to the side of the horizontal infusion pipe 1, the elastic control valve 2 is set at the upper end of the horizontal infusion pipe 1 by pre-calculating the storage capacity of the removable liquid storage container 4 and the drainage capacity of the electrically controlled water valve 5. When the main frame 3 moves to the lower end of the elastic control valve 2, the top permanent magnet 24 located at the upper end of the removable liquid storage container 4 magnetically attracts the elastic control valve 2, and then automatically opens the connection between the elastic control valve 2 and the horizontal infusion pipe 1. After that, the lower outlet of the elastic control valve 2 is inserted into the upper inlet of the removable liquid storage container 4, and the horizontal infusion pipe 1 replenishes water to the removable liquid storage container 4 through the elastic control valve 2, thereby keeping the removable liquid storage container 4 full of water.

[0043] The contact surface between the elastic control valve 2 and the top liquid inlet seat 23 is a frustum-shaped structure, which allows the main frame 3 to automatically control the separation of the elastic control valve 2 and the top liquid inlet seat 23 during translation.

[0044] The resilient control valve 2 includes an inverted L-shaped side-mounted water guide pipe fixed to the horizontal infusion pipe 1, a lateral control seat fixed to the top of the side-mounted water guide pipe, and an internal drain pipe inserted into the lateral control seat via an internal spring. The connection between the side-mounted water guide pipe and the lateral control seat is opened and closed by raising and lowering the internal drain pipe. When it descends and extends, the connection between the side-mounted water guide pipe and the lateral control seat is opened, and the side-mounted water guide pipe supplies liquid into the internal drain pipe, which then guides the liquid into the top inlet seat 23.

[0045] This invention discloses a large-volume concrete raft foundation construction and curing device and method. A main frame 3, controlled by a four-way drive wheel assembly and a lifting mechanism, moves in a serpentine pattern across the construction surface of the large-volume concrete raft foundation. An electrically controlled water valve 5 evenly sprays cooling water from the detachable liquid storage container 4 at its upper end onto the construction surface, eliminating the need for manual operation, saving time and labor, and enabling 24-hour uninterrupted curing. The automated curing operation not only allows for automatic detection but also automatic replenishment of the detachable liquid storage container 4, improving operational endurance and significantly increasing curing efficiency. A bottom monitoring system is also included. The rolling universal assembly 8 transmits the surface condition to the temperature and humidity sensor controller 7, which can avoid the temperature and humidity sensor controller 7 being affected by the external environment, improve detection accuracy, and greatly reduce energy consumption. By providing a lateral storage groove 25 for installing the flip assembly frame 10 on the outer side of the main frame 3, and fixing an LED status indicator light 26 for displaying the monitoring status of the infrared distance sensor 9 on the inner side of the lateral storage groove 25, the monitoring interval of the maintenance device is adjustable. This allows for a more intuitive understanding of the position of the maintenance device in low light conditions, facilitating the understanding of its working status.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
