Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, and in particular relates to a concrete tailing flow rate switch device. Background Art

[0002] When using a sky pump to pour concrete, the concrete pouring pipe that comes with the commercial concrete station's sky pump is used for construction. The end of this pouring pipe is a rubber hose. However, at the end of pouring concrete in each area, the remaining concrete in the concrete pouring pipe naturally flows out of the pipe, making it impossible to effectively control the pouring flow rate. This can easily cause over-pouring and overflow of concrete in one area, resulting in material waste. In addition, after pouring concrete in each area, the sky pump no longer pressurizes the concrete. At this time, the construction workers need to move the sky pump's concrete pouring pipe to the next area for pouring. During the movement, the concrete in the concrete pouring pipe will fall, resulting in residual concrete residue on the slab surface along the concrete pouring pipe's movement path, causing cold joints in the later top slab construction and affecting construction quality.

[0025] See also Figure 1 , Figure 1This is a cross-sectional view of a concrete tailings flow rate switch device according to the present invention. The device comprises a tube 1, a switch bearing 2, a flow rate control plate 3, and a locking mechanism. The tube 1 is mounted on the end of a concrete pouring pipe of a sky pump. The switch bearing 2 radially extends through the tube 1 and is movably connected to the tube 1. The flow rate control plate 3 is disposed within the tube 1 and is connected to the switch bearing 2. Driven by the switch bearing 2, the flow rate control plate 3 can rotate vertically to control the flow rate of concrete through the tube 1. A locking mechanism is provided on the tube 1 to secure or release the switch bearing 2.

[0026] When the concrete tailing flow rate switch device of the present invention is used, one end of the tube 1 is inserted into the end of the concrete pouring pipe of the sky pump, and then fixed by the hoop provided with the sky pump. When pouring concrete, the flow rate control plate 3 can be driven to rotate vertically by rotating the switch bearing 2, thereby adjusting the angle between the flow rate control plate 3 and the vertical plane, thereby controlling the flow rate of concrete through the tube 1. After the concrete pouring is completed, the sky pump no longer applies pressure, and the flow rate control plate 3 is driven to rotate vertically to a horizontal state by rotating the switch bearing 2. Since the specifications and dimensions of the flow rate control plate 3 are the same as those inside the tube 1, the flow rate control plate 3 now closes the tube 1, so that the remaining concrete in the concrete pouring pipe and the tube 1 no longer falls, thereby avoiding concrete waste, and avoiding over-pouring and overflow of concrete in one part, saving costs, and improving concrete utilization. During the process of moving the concrete pouring pipe of the sky pump to the next pouring point, the flow rate control plate 3 is driven to rotate vertically to a horizontal state by rotating the switch bearing 2. At this time, the flow rate control plate 3 closes the pipe tube 1 to prevent the concrete pouring pipe and the concrete in the pipe tube 1 from falling off and contaminating the floor slab during the movement of the concrete pouring pipe, preventing the secondary pouring from causing cold joints and affecting the construction quality, and improving the quality of the concrete pouring in one time.

[0027] In one embodiment, the locking mechanism includes a first limiting nut 4, the interior of which is a regular polygonal hole. The first limiting nut 4 is sleeved on the outside of the switch bearing 2 and is arranged on the outer wall of the tube 1. The switch bearing 2 is provided with a second limiting nut 5 that is plugged into and matched with the first limiting nut 4. The second limiting nut 5 has an outer contour that matches the regular polygonal hole. The diameter of the flow rate control plate 3 is smaller than the inner diameter of the tube 1. Since the diameter of the flow rate control plate 3 is smaller than the inner diameter of the tube 1, the switch bearing 2 can rotate on the tube 1 and can move horizontally on the tube 1. Figure 1As shown, when the flow rate of the concrete in the tube 1 needs to be adjusted, first pull the switch bearing 2 to the right and pull the second limit nut 5 on the switch bearing 2 out of the first limit nut 4. At this time, the flow rate control plate 3 can be driven to rotate in the vertical direction by rotating the switch bearing 2 to adjust the inclination of the flow rate control plate 3. The inclination of the flow rate control plate 3 is continuously changed to adjust the flow rate of the concrete in the tube 1. When the flow rate control plate 3 is rotated to a vertical state, that is, the flow rate control plate 3 is parallel to the tube 1, the tube 1 is in a fully open state at this time, and the flow rate of the concrete in the tube 1 is the largest. The flow rate control plate 3 is rotated to a horizontal state, that is, the flow rate control plate 3 is perpendicular to the tube 1. At this time, the flow rate of the concrete in the tube 1 is the smallest, and the diameter of the flow rate control plate 3 is slightly smaller than the internal diameter of the tube 1. The flow rate control plate 3 can now basically close the tube 1 to prevent the concrete in the tube 1 from falling.

[0028] After adjustment is complete, push the switch bearing 2 to the left and insert the second stop nut 5 on the switch bearing 2 into the first stop nut 4. The first and second stop nuts 4 and 5 cooperate to secure the switch bearing 2, preventing it from rotating on the tube 1. In one embodiment, a fixing plate 6 is provided at one end of the switch bearing 2, with the fixing plate 6 and the second stop nut 5 positioned on either side of the tube 1. A spring 7 is mounted on the fixing plate 6 and sleeved onto the outside of the switch bearing 2. The deformation of the spring 7 before and after compression provides an elastic force to automatically restore the position of the switch bearing 2, preventing the second stop nut 5 on the switch bearing 2 from slipping out of the first stop nut 4 and causing the switch bearing 2 to rotate on the tube 1. In one embodiment, a pressure plate 8 is provided on the end of the spring 7 away from the fixing plate 6. The pressure plate 8 increases the contact area between the spring 7 and the tube 1, preventing the spring 7 from slipping on the tube 1.

[0029] In order to facilitate the rotation of the switch bearing 2, in one embodiment, a handle 9 is provided at one end of the switch bearing 2 away from the fixing plate 6. The handle 9 is arranged perpendicular to the switch bearing 2, making it convenient for construction workers to rotate the switch bearing 2 through the handle 9.

[0030] In one embodiment, a circle of fixing grooves 10 are provided along the circumference of the outer wall of the tube 1. When the tube 1 is installed in the concrete pouring pipe of the sky pump, it is generally fixed by a hoop. The fixing grooves 10 are provided on the tube 1 so that the hoop can be placed in the fixing grooves 10, thereby making the connection between the concrete pouring pipe and the tube 1 more stable.

[0031] In one embodiment, several handrails 11 are provided on the outer wall of the tube 1. Construction workers can use these handrails 11 to secure the tube 1 during concrete pouring or to move it when necessary. In one embodiment, there are two handrails 11, symmetrically positioned on the outer wall of the tube 1. In one embodiment, the outer sides of the handrails 11 are covered with anti-slip sleeves to prevent slipping.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
