TECHNICAL FIELD
[0001] The utility model relates to underwater concrete construction's technical field especially is related to a kind of underwater concrete pouring automatic lifting test device. BACKGROUND
[0002] Underwater concrete pouring is a common construction technique in water conservancy projects, bridge construction, ports and marine engineering. Traditional underwater concrete pouring techniques face many challenges, such as difficulty in controlling pouring accuracy, easy mixing of concrete and water interface, concrete layering and segregation, etc. In order to improve the quality and efficiency of underwater pouring, while reducing environmental impact and construction cost, the development of automation and intelligent devices has become an important direction for industry development. In underwater concrete pouring, accurate control of the depth of the guide pipe is crucial, as the depth of the guide pipe directly affects the quality and structural integrity of the concrete pouring.
[0003] Traditional underwater concrete pouring methods often rely on the skills and experience of operators to manually control the height of the guide pipe, which has certain uncertainty and risk. When adjusting the height of the guide pipe, operators may make mistakes in judgment, causing the guide pipe to be too high, exposing the concrete directly to water, which can cause quality problems such as concrete segregation and layering, and even lead to pouring failure. Based on this, we propose a kind of underwater concrete pouring automatic lifting test device. UTILITY MODEL CONTENT

Cables are wound around the outside of the four sets of drive wheels. A telescopic tube is installed inside the container. A conductor float is installed at the bottom of the inner cavity of the telescopic tube. A contact point is installed at the end of the inner cavity of the telescopic tube away from the conductor float, and the top of the contact point is fixedly connected to the bottom of the cable.
[0007] By adopting the above technical solution, water is injected into the container, and the water level is adjusted until it just touches the conductor float at the bottom of the telescopic pipe. Then, concrete is injected into the hopper. The concrete flows into the container through the discharge hopper and the conduit. As the concrete is poured, the water level rises with the height of the concrete surface, pushing the conductor float upward inside the telescopic pipe. When the conductor float touches the contact point inside the telescopic pipe, the circuit is connected. At this time, the drive wheel moves, the hinge angle on the moving support decreases, and the discharge hopper moves upward. The conduit moves upward accordingly. When the conduit is raised to a certain height, the conductor float disengages from the contact point, the circuit is broken, the drive wheel stops moving, and the conduit stops rising. At this time, the concrete embedment depth is maintained at the designed embedment depth. Through the above operation, the height of the conduit can be adjusted quickly and accurately, reducing the impact of human operation on the construction process and reducing the probability of operational errors and accidents.

[0012] Optionally, the movable support includes two top rods, which are respectively connected to the lower ends of both sides of the hopper. The front and rear ends of the two top rods are hinged to movable rods. The bottoms of the four movable rods are respectively connected to four sets of drive wheels. Support rods are connected between the two movable rods on the left end and the two movable rods on the right end.
[0013] By adopting the technical scheme, the driving wheel can drive the moving rod to move when the driving wheel moves, and the included angle between the moving rod and the top rod can be adjusted, so that the top rod can push the lower hopper to move upward, and the guide pipe can move upward.
[0014] Optionally, the driving wheel comprises four groups of driving motors, each of the four groups of driving motors is provided with a roller at a power output end, and each of the four groups of driving motors is provided with a power supply at a top portion.
[0015] By adopting the technical scheme, the driving motor is provided with a power source through the power supply, and the roller rotates when the driving motor works, so that the roller can move along the wheel groove.
[0016] Optionally, an anti-return clamping groove is arranged in the wheel groove, and a switch is arranged on the anti-return clamping groove.

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.
[0026] Please refer to the attached diagram in the instruction manual. Figure 1 This utility model provides an embodiment of an automatic lifting test device for underwater concrete pouring, comprising a hopper 1 and a fixed frame 6, with the hopper 1 located above the fixed frame 6. A container 7 is fixedly installed inside the fixed frame 6. Support columns 14 are vertically connected to both ends of the bottom of the hopper 1, and discharge hoppers 3 are fixedly installed at the bottom of the two sets of support columns 14. A switch 2 is provided in the middle of the bottom of the hopper 1. By opening the switch 2, concrete can fall into the discharge hopper 3; by closing the switch 2, the concrete discharge stops.
[0027] Please refer to the attached diagram in the instruction manual. Figure 1 A guide tube 4 is fixedly connected to the bottom of the hopper 3, and the bottom of the guide tube 4 extends into the interior of the container 7. A movable support 5 is installed on the outside of the hopper 3. The movable support 5 includes two push rods 501, which are fixedly connected to the lower ends of both sides of the hopper 3. The front and rear ends of the two push rods 501 are hinged to movable rods 503. The bottoms of the four movable rods 503 are connected to four sets of drive wheels 13. Support rods 502 are fixedly connected between the two movable rods 503 on the left end and the two movable rods 503 on the right end. When the drive wheels 13 move, they can drive the movable rods 503 to move, thereby adjusting the angle between the movable rods 503 and the push rods 501. This allows the push rods 501 to push the hopper 3 upward, which in turn drives the guide tube 4 upward.
[0028] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 The movable support 5 has four drive wheels 13 installed at its bottom corners. The top of the fixed frame 6 has wheel grooves 12 that match the drive wheels 13. The drive wheels 13 include four drive motors 1302. Rollers 1303 are installed at the power output ends of the four drive motors 1302. Power supplies 1301 are installed on the top of the four drive motors 1302. The power supplies 1301 provide power to the drive motors 1302. When the drive motors 1302 are working, they drive the rollers 1303 to rotate, thereby enabling the rollers 1303 to move along the wheel grooves 12.
[0029] Please refer to the attached diagram in the instruction manual. Figure 1 The wheel groove 12 has a backstop groove inside, and a switch is installed on the backstop groove. When the switch is turned on, the roller 1303 can slide freely in the wheel groove 12. When the switch is turned off, the roller 1303 can only move inward and cannot move outward.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 Four sets of drive wheels 13 are wound with cables 8 on their outer sides. A telescopic tube 10 is installed inside the container 7. A conductor float 11 is installed at the bottom of the inner cavity of the telescopic tube 10. An opening is provided at the bottom of the telescopic tube 10, and the diameter of the conductor float 11 is smaller than the diameter of the telescopic tube 10. The opening allows water to flow into the telescopic tube 10. When there is water at the bottom of the telescopic tube 10, the float 11 moves upward within the telescopic tube 10 to the height of the contact point 9. A contact point 9 is provided at the end of the inner cavity of the telescopic tube 10 away from the conductor float 11, and the top of the contact point 9 is fixedly connected to the bottom of the cable 8.
[0031] Working principle: When in use, the operator first adjusts the angle of the moving bracket 5 so that its whole body is at 90° with the vertical direction, that is, the moving bracket 5 is in a horizontal state. Then, the operator adjusts the length of the telescopic tube 10 to set the distance between the conductor float 11 and the contact point 9. After the adjustment is completed, water is injected into the container 7 and the water level is adjusted until it just touches the conductor float 11 at the bottom of the telescopic tube 10.
[0032] Next, concrete is injected into the collection hopper 1 and the switch 2 is turned on. The concrete flows into the container 7 through the discharge hopper 3 and the conduit 4. As the concrete is poured, the water level rises with the height of the concrete surface, pushing the conductor float 11 to move upward inside the telescopic tube 10. When the conductor float 11 touches the contact point 9 inside the telescopic tube 10, the circuit is connected. At this time, the drive motor 1302 works to drive the roller 1303 to rotate, making it move inward along the wheel groove 12. As the roller 1303 moves, the included angle between the top rod 501 and the moving rod 503 decreases, thereby pushing the discharge hopper 3 to move upward, and the conduit 4 moves upward accordingly.
[0033] When the conduit 4 is raised to a certain height, the conductor float 11 disengages from the contact 9, the circuit is broken, the roller 1303 stops moving, and the conduit 4 also stops rising. At this time, the concrete embedment depth is maintained at the designed embedment depth, ensuring the consistency and quality of the pouring. Through the above operation, the height of the conduit 4 can be adjusted quickly and accurately, reducing the impact of human operation on the construction process and reducing the probability of operational errors and accidents.
[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
