[0016] See also Figures 1 to 3In an embodiment of the present invention, a tool suitable for vertical transportation of thin-walled concrete pouring in a large wellbore is provided, comprising a buffer 1, one end of the buffer 1 being connected to a chute 4, and the other end of the buffer 1 being connected to a joint pipe 3, a stirring cover 8 being provided in the middle of the upper end of the buffer 1, and an inspection window 6 being provided at a side position of the upper end of the buffer 1 close to the stirring cover 8, a stirring motor 9 being provided inside the stirring cover 8, a stirring shaft 10 being provided vertically on the lower end of the stirring motor 9 located inside the buffer 1, and a stirring blade 11 being provided on the stirring shaft 10, and the function of mixing concrete can be achieved by driving the stirring motor 9 to drive the stirring shaft 10 to rotate, and the rotation of the stirring shaft 10 drives the stirring blade 11 to rotate,
[0017] The limiting structure 15 includes a pull protrusion 17, a connecting rod 18, a docking block 19, a movable block 20 and a spring 21. The movable block 20 is installed inside the movable groove 16, and one end of the movable block 20 is connected to the spring 21, and the other end is provided with a docking block 19. The upper end of the movable block 20 is provided with a connecting rod 18, and the connecting rod 18 is provided with a pull protrusion 17. The top of the inspection window 6 is provided with a limiting block 14 that matches the limiting structure 15. The upper surface of the docking block 19 is an arc-shaped structure, and the lower surface is a flat structure. The upper side of the limit card block 14 is a flat structure, and the lower surface is an arc-shaped structure. When the inspection window 6 is pressed down, the limit card block 14 squeezes the docking block 19, prompting the movable block 20 to apply pressure to the spring 21, which can move backward. When the limit card block 14 is disengaged from the extrusion of the docking block 19, the spring 21 is reset. At this time, the lower surface of the docking block 19 contacts the upper surface of the limit card block 14, which can limit the position. When it needs to be opened, manually pull the movable protrusion 17 to compress the spring 21 to provide space for the limit card block 14 to move upward.
[0018] One end of the inspection window 6 is rotatably connected to the buffer 1 through a hinge 5, and a sealing insert 13 is provided on one side of the inspection window 6, and a protrusion 7 is provided on the upper surface of the inspection window 6 to facilitate staff to open it and inspect the inside of the buffer box.
[0019] Two foot pads 2 are provided at the lower end of the buffer 1. The foot pads 2 are rubber components that play a buffering role to prevent the heavy concrete from crushing the supporting object.
[0020] A buffer inclined plate 12 is provided on one side of the bottom of the buffer 1. The buffer inclined plate 12 is provided on the side close to the joint pipe 3.
[0021] The working principle of the utility model is: during the specific implementation, the concrete pouring pipe is placed vertically, and the joint is connected to the next-level pouring pipe to achieve the purpose of graded buffering. The concrete enters the chute 4 from the inlet hopper and then enters the buffer 1, which can buffer, reduce the speed and re-mix the concrete. The joint pipe 3 can be connected to the next section of the chute, thereby achieving the purpose of graded buffering; the inspection window is used for maintenance when the concrete is solidified in the buffer 1. The concrete pouring pipe with a buffer can slow down the concrete during the vertical pouring process. When the concrete passes through the buffer, the flow rate can be reduced and the concrete can be moved horizontally for a distance in the buffer box, so that the aggregate can be re-mixed to prevent the separation of concrete aggregates. The device is suitable for vertical transportation of concrete in pressure-regulating wells, and solves the problems of segregation and water seepage and construction difficulties caused by the excessive length of the traditional concrete pouring pipe, simplifies the construction process, reduces safety risks, and improves construction quality. The buffer can buffer, reduce the speed and re-mix the concrete.
[0022] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
