Description

Technical Field

[0001] This utility model relates to an adjustable concrete pouring thickness control device for floor slabs, and in particular to an adjustable concrete pouring thickness control device for floor slabs, belonging to the field of concrete pouring technology. Background Technology

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete should not exceed 2m. If it exceeds 3m, corresponding measures should be taken.

[0003] A search revealed Chinese patent publication number CN212317515U, which discloses an adjustable concrete pouring thickness control device for floor slabs. This device includes an elevation cylinder, support legs, a movable rod, and an elevation rod. The lower end of the elevation cylinder is supported by the support legs. The elevation cylinder is a cylindrical hollow structure. The movable rod extends downwards through the elevation cylinder and can move freely up and down along the cylinder. A long, narrow opening is formed vertically along the cylinder. Multiple support openings perpendicularly connected to the long, narrow opening are formed on both sides of the opening. The elevation rod is vertically fixed to the movable rod and can move freely within the support openings and the long, narrow opening, and can be placed within the support opening. This adjustable concrete pouring thickness control device effectively solves the problem of unstable floor slab thickness and is reusable.

[0004] The adjustable concrete pouring thickness control device in the aforementioned patent has the following shortcomings: The device uses multiple support openings on the elevation cylinder to represent the thickness of the fixed floor slab. However, in actual use, operators cannot read the thickness of the concrete slab in real time through the support openings. After measuring the floor slab thickness, the support openings must be manually adjusted, which is quite cumbersome. Furthermore, construction workers need to insert their feet into the poured concrete slab and move the moving rod back and forth to level the thickness of the poured concrete, which affects the pouring quality of the concrete slab. Moreover, it cannot achieve automated real-time detection of the concrete pouring thickness.

[0005] Therefore, it is urgent to improve the concrete pouring thickness control device for floor slabs in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable concrete pouring thickness control device for floor slabs. It adopts an automated pouring thickness setting structure. After the device is installed, it can accurately measure the thickness remotely and non-contactly using a laser rangefinder. During pouring, when the concrete surface reaches the thickness position indicated by the laser rangefinder, the data is transmitted in real time to the PLC controller and remotely displayed on the construction personnel's controller via a communication module. This allows for timely stopping of concrete pouring, thereby achieving automatic control of the concrete pouring thickness for floor slabs.

[0007] To achieve the above objectives, the main technical solution adopted by this utility model includes: a sleeve rod and a threaded rod rotatably disposed inside the sleeve rod. A ball screw pair is installed at one end of the threaded rod, and an mounting component is installed on one side of the ball screw pair.

Several fixing brackets are installed on one side of the sleeve rod. A limit block is fixedly installed on one side of the fixing bracket. A photoelectric switch is installed inside the limit block. A PLC controller is installed on one side of the sleeve rod.

[0014] This utility model has at least the following beneficial effects:

[0015] Through a threaded rod, a ball screw pair, a photoelectric switch, and a PLC controller, the threaded rod drives the ball screw pair to move the laser rangefinder to the specified thickness setting position, thereby achieving the effect of automating the setting of the rated thickness of the pouring.

[0016] By combining a laser rangefinder with a constructed pouring baffle, a dual-layer pouring thickness control system can be established, enabling the detection of the thickness of already poured concrete and achieving the effect of controlling the pouring thickness of floor slab concrete.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-4As shown, an adjustable concrete pouring thickness control device for floor slabs includes a sleeve rod 1 and a threaded rod 6 disposed inside the sleeve rod 1. A ball screw pair 10 is mounted on the surface of the threaded rod 6, and a mounting part 11 is mounted on the surface of the ball screw pair 10. A laser rangefinder sensor 12 is placed inside the mounting part 11. Two clamping blocks 15 are mounted above the laser rangefinder sensor 12. Several fixing brackets 4 are mounted on one side surface of the sleeve rod 1. Limiting blocks 19 are mounted on the upper surface of the fixing brackets 4. A photoelectric switch 5 is placed inside the limiting block 19. A PLC controller 7 is mounted on one side of the sleeve rod 1. In this embodiment, the laser rangefinder sensor 12, photoelectric switch 5, PLC controller 7, servo motor 3, and ball screw pair 10 mentioned are all existing technical features. Specifically, the laser rangefinder sensor 12 is a Steinbang SGL-250NM, the photoelectric switch 5 is a Panasonic EH-R1000, and the PLC controller 7 is an Omron CP1H. Series - RS232C, the model used for servo motor 3 is Mitsubishi MR-J4 series, the model used for ball screw pair 10 is FFZD3205-3;Therefore, this embodiment will not elaborate further. Before pouring the floor slab concrete, a concrete pouring baffle is constructed according to the specific thickness of the floor slab to be poured. The equipment is installed and fixed on the absolutely horizontal surface of one side of the concrete pouring baffle through the lower fixing base 9. The photoelectric switch 5 located on which layer is selected according to the thickness of the floor slab pouring is electrically connected to the PLC controller 7 through the wiring port 14 and wires (not mentioned in the figure). Three photoelectric switches 5 are clamped and installed on one side of the sleeve rod 1 through the fixing bracket 4 and the limiting block 19, corresponding to 100mm, 150mm and 200mm from bottom to top respectively. The photoelectric switch 5 and the PLC controller can be selected according to the thickness of different floor slab pouring. 7. For large shopping malls, considering the large flow of people and goods, the floor slab thickness is usually between 150mm and 200mm. Therefore, the photoelectric switch 5 at the top of the sleeve 1 can be connected to the PLC controller 7. The operator uses two clamping blocks 15 to fix the laser rangefinder 12 inside the mounting part 11. The PLC controller 7 remotely controls the servo motor 3 to drive the threaded rod 6 to rotate inside the sleeve 1. Under the action of the ball screw pair 10, the ball screw pair 10, which was originally rotating on the surface of the threaded rod 6, becomes a linear vertical upward sliding, thereby driving the laser rangefinder 12 to rise. After reaching the position of the photoelectric switch 5 at the top, the photoelectric switch 5 activates in real time. The signal is transmitted from the connection port 14 to the PLC controller 7 via a wire (not shown in the diagram). The PLC controller 7 then sends an electrical signal through the electrical connection 18 to the servo motor 3, controlling the servo motor 3 to shut down. This fixes the position of the laser rangefinder 12. The appropriate number of devices is installed based on the size of the concrete slab surface to be poured, and concrete pouring begins. After a certain time, the thickness of the concrete is observed at the pouring baffle. The PLC controller 7 is then remotely controlled to activate the electrically connected laser rangefinder 12, detecting the thickness of the poured concrete. If the thickness has not yet reached the point where the laser rangefinder 12 emits its laser beam, the construction personnel can proceed with... For small-volume concrete pouring, the thickness of the concrete at the pouring baffle is observed, and the laser range sensor 12 is activated again for detection. If the thickness exceeds the thickness position emitted by the laser range sensor 12, it will be fed back to the construction personnel's control equipment in real time through the communication module inside the PLC controller 7. Then, a small amount of the poured concrete needs to be removed to prevent the poured concrete from exceeding the rated pouring thickness. This, together with the erected pouring baffle, forms a dual pouring thickness control, so that the pouring thickness of the floor slab concrete can be effectively controlled within a reasonable thickness range. After the pouring is completed, the construction personnel still need to correct the flatness of the floor slab concrete, but they do not need to correct the thickness inside the floor slab concrete, thus achieving the effect of controlling the pouring thickness of the floor slab concrete.

[0025] It should be noted that this structure is only applicable to level ground. For more sloping ground, it needs to be installed at multiple nodes at different heights to control the operation on ground with a large tilt angle.

[0026] Furthermore, such as Figures 1-3 As shown, a servo motor 3 is mounted on the upper surface of the sleeve 1. A transmission rod 17 is fixedly mounted on the output end of the servo motor 3. A first limiting bearing 2 is mounted on the upper inside of the sleeve 1, and a second limiting bearing 16 is mounted on the lower inside of the sleeve 1. The end of the transmission rod 17 away from the servo motor 3 passes through the sleeve 1 and the first limiting bearing 2 and connects to the upper end of the threaded rod 6. The end of the threaded rod 6 away from the first limiting bearing 2 is connected to the second limiting bearing 16. The threaded rod 6 is rotated and mounted inside the sleeve 1 under the drive of the transmission rod 17. The presence of the first limiting bearing 2 and the second limiting bearing 16 can maximize the limitation of the rotation position of the threaded rod 6 inside the sleeve 1, and avoid positional displacement under the drive of the transmission rod 17, which would affect the overall thickness detection effect.

[0027] Furthermore, such as Figures 1-4 As shown, the ball screw assembly 10 is slidably mounted on the surface of the threaded rod 6, the mounting part 11 is fixedly mounted on the surface of the ball screw assembly 10, the clamping block 15 is snapped onto the top of the mounting part 11, the laser rangefinder 12 is mounted and fixed inside the mounting part 11 through the clamping block 15, two irradiation heads 13 are fixedly mounted on one side of the laser rangefinder 12, two mounting holes 20 are opened on one side of the fixing frame 4, the fixing frame 4 is fixedly mounted on one side of the sleeve rod 1 through the mounting holes 20, the limit block 19 is fixedly mounted on the upper surface of the fixing frame 4, and the photoelectric switch 5 is placed on the limit block 19. Inside the position block 19, one end of the photoelectric switch 5 is equipped with a wiring port 14. The PLC controller 7 is fixedly installed on the surface of the sleeve rod 1. When the laser range sensor 12 is working, the emitted laser is diffused through two irradiation heads 13 on one side. For example, with a casting thickness of 200mm, under the irradiation of the irradiation head 13, the bottom corner irradiation angle can be controlled within the casting thickness range of 196mm-198mm. It is not possible to directly reach the casting thickness of 200mm before control is performed, because there is enough reaction difference for thickness control, ensuring the accuracy of casting thickness control.

[0028] Furthermore, such as Figures 1-3As shown, a battery compartment 8 is installed on one side of the sleeve rod 1, and an electrical connection 18 is installed on the upper surface of the PLC controller 7. The electrical connection 18 is used for electrical connection. The photoelectric switch 5 is electrically connected to the PLC controller 7 through the wiring port 14. The battery compartment 8 is fixedly installed on one side of the sleeve rod 1, and a portable battery is installed inside the battery compartment 8. A fixed base 9 is fixedly installed at the lower end of the sleeve rod 1. A portable battery (not mentioned in the figure) is installed inside the battery compartment 8. The portable battery can power the electrical equipment mentioned in the device, and can be removed for recharging after a period of operation, achieving the effect of portable charging.

[0029] In this embodiment, as Figures 1-4 As shown in the figure, the principle of the adjustable floor slab concrete pouring thickness control device provided in this embodiment is as follows:

[0030] Before pouring the concrete for the floor slab, a concrete pouring baffle is constructed according to the required thickness of the floor slab. The equipment is fixed to the absolutely horizontal surface of one side of the concrete pouring baffle using the lower fixing base 9. Based on the thickness of the floor slab pouring, the photoelectric switch 5 is selected and electrically connected to the PLC controller 7 via the wiring port 14 and wires (not mentioned in the diagram). Three photoelectric switches 5 are clamped and installed on one side of the sleeve rod 1 using the fixing bracket 4 and the limiting block 19, corresponding to 100mm, 150mm, and 200mm from bottom to top. The photoelectric switch 5 at the corresponding installation position can be selected and connected to the PLC controller 7 according to the different thicknesses of the floor slab pouring. (Example: A large shopping mall...) Considering the large flow of people and the load of goods, the floor slab thickness is usually between 150mm and 200mm. Therefore, the photoelectric switch 5 located at the top of the sleeve rod 1 can be connected to the PLC controller 7. The operator uses two clamping blocks 15 to fix the laser rangefinder 12 inside the mounting part 11. The PLC controller 7 remotely controls the servo motor 3 to drive the threaded rod 6 to rotate inside the sleeve rod 1. Under the action of the ball screw pair 10, the ball screw pair 10, which was originally rotating on the surface of the threaded rod 6, becomes a linear vertical upward sliding, thereby driving the laser rangefinder 12 to rise. After reaching the position of the photoelectric switch 5 at the top, the photoelectric switch 5 is connected in real time through the wiring port 14. The wire (not mentioned in the diagram) conducts to the interior of the PLC controller 7, which then sends an electrical signal through the electrical connection 18 to the servo motor 3, controlling the servo motor 3 to shut down. This fixes the position of the laser rangefinder 12. The appropriate number of devices is installed based on the size of the floor slab surface to be poured, and concrete pouring begins. After a certain time, the thickness of the concrete is observed at the pouring baffle. The PLC controller 7 is then remotely controlled to activate the electrically connected laser rangefinder 12, detecting the thickness of the poured concrete. If the thickness has not yet reached the point where the laser rangefinder 12 emits its laser beam, the construction personnel can apply a small amount of concrete. During concrete pouring, the thickness of the concrete at the pouring baffle is observed, and the laser rangefinder 12 is activated again for detection. If the thickness exceeds the thickness range indicated by the laser rangefinder 12, the communication module inside the PLC controller 7 will provide real-time feedback to the construction personnel's control equipment. In this case, a small amount of the poured concrete needs to be removed to prevent the poured concrete from exceeding the rated pouring thickness. This, together with the erected pouring baffle, forms a dual control over the pouring thickness, ensuring that the pouring thickness of the floor slab concrete can be effectively controlled within a reasonable range. After pouring, the construction personnel still need to correct the flatness of the floor slab concrete, but they do not need to correct the thickness inside the floor slab concrete, thus achieving the effect of controlling the pouring thickness of the floor slab concrete.
