AI Technical Summary
Existing technologies for concrete pouring, especially for pile foundation pouring, suffer from high construction costs, low work efficiency, and complex operations. Furthermore, the extension of the guide pipe can only meet the depth requirements of each section of the guide pipe and cannot effectively prevent concrete segregation.
A concrete pouring guide device is adopted, including a guide pipe control part and a pouring guide pipe part. The extension and retraction of the pouring guide pipe are controlled by a support frame, a winch, a rope winding roller and a guide pulley. The length of the guide pipe can be flexibly adjusted by controlling the rope to connect the inlet, middle and outlet guide pipe flanges, and maintaining the distance between the pouring port and the pouring surface.
It enables flexible adjustment of the length of the guide pipe, ensuring the quality of pouring, simplifying the operation, reducing construction costs, improving work efficiency, and preventing concrete segregation.

TECHNICAL FIELD
[0001] The utility model relates to the equipment of building construction uses, especially a concrete pouring flow guide device. BACKGROUND
[0002] In the prior art, during the concrete pouring process of building construction, especially during the pouring process of pile foundation, the technical requirement is that the outlet of the concrete pump pipe must maintain a designed distance from the pouring surface to prevent the concrete from forming a too high free fall, which causes the segregation of concrete, i.e., the separation of coarse aggregate and mortar, cement slurry and aggregate, and water and solid materials, thereby affecting the pouring quality. This is especially true for the concrete pouring of relatively deep pile foundations.
[0003] In the prior art, the method used to solve the segregation of concrete caused by the formation of a too high free fall of concrete is as follows: 1. As the pouring depth of concrete increases, the pouring guide pipe is gradually lifted and lengthened using a crane; and 2. A sleeve pipe is used to increase the length of the pouring guide pipe that can be extended downward as the pouring depth of concrete increases. For example, a kind of pouring guide pipe suitable for pouring concrete at different depths and a method for using the same are disclosed in Chinese Patent Publication CN111827294.A.
[0004] The disadvantage of the prior art 1 is that it requires the use of hoisting equipment, increases construction costs, and has low work efficiency. The disadvantage of the prior art 2 is that it has low work efficiency, complex operation, and the extension of the guide pipe can only meet the depth requirement of each section of the guide pipe. SUMMARY

[0007] The flow guide pipe control part comprises a support frame, a winch, a rope winding roller, a guide pulley, and a control rope.
[0008] The winch is arranged on the support frame, and the control rope is arranged in two pieces, each fixed at one end to the rope winding roller on the winch. One end of the control rope is fixedly connected to the pouring flow guide pipe part via the guide pulley.
[0009] The pouring flow guide pipe part comprises: an inlet flow guide pipe, an intermediate flow guide pipe and an outlet flow guide pipe, the inlet flow guide pipe, the intermediate flow guide pipe and the outlet flow guide pipe are respectively provided with an inlet flow guide pipe flange, an intermediate flow guide pipe flange and an outlet flow guide pipe flange, and the inlet flow guide pipe, the intermediate flow guide pipe and the outlet flow guide pipe are sequentially sleeved to form a relative telescopic movable connection, and the two control ropes are respectively fixedly connected with the outlet flow guide pipe flange through the through holes in the inlet flow guide pipe flange and the intermediate flow guide pipe flange.
[0010] The concrete pouring flow guide device has the advantages of simple structure, convenient use, and the length of the pouring flow guide pipe part being capable of being changed at will along with the pouring depth of the concrete, so that the pouring opening position of the concrete is kept at a specified distance from the pouring surface at all times, and the pouring quality is ensured.

DETAILED DESCRIPTION
[0014] Referring to the drawings. A concrete pouring flow guide device comprises: a flow guide pipe control part and a pouring flow guide pipe part.
[0015] The flow guide pipe control part comprises: a support frame 1-1, a winch 1-2, a rope winding roller 1-3, a guide pulley 1-4 and a control rope 1-5.
[0016] The winch 1-2 is arranged on the support frame 1-1, the control rope 1-5 is arranged in two, one end of each of the control ropes 1-5 is fixed on the rope winding roller 1-3 on the winch 1-2, and one end of the control rope 1-5 is fixedly connected with the pouring flow guide pipe part through the guide pulley 1-4.
[0017] When working, the telescopic pouring flow guide pipe part is controlled by the rope winding roller 1-3, the control rope 1-5 and the guide pulley 1-4 on the winch 1-2, so that the pouring height can be changed and the pouring flow guide pipe part can be retracted after use.
[0018] The casting guide pipe section includes: an inlet guide pipe 2-1, an intermediate guide pipe 2-2, and an outlet guide pipe 2-3. The inlet guide pipe 2-1, the intermediate guide pipe 2-2, and the outlet guide pipe 2-3 are respectively provided with an inlet guide pipe flange 2-11, an intermediate guide pipe flange 2-21, and an outlet guide pipe flange 2-31. The inlet guide pipe 2-1, the intermediate guide pipe 2-2, and the outlet guide pipe 2-3 are sequentially fitted together to form a relatively telescopic movable connection. The two control ropes 1-5 are fixedly connected to the outlet guide pipe flange 2-31 through the through holes on the inlet guide pipe flange 2-11 and the intermediate guide pipe flange 2-21, respectively.
[0019] During operation, as the pouring progresses, the pouring surface continuously rises. Control rope 1-5 shortens the total length of the inlet guide pipe 2-1, intermediate guide pipe 2-2, and outlet guide pipe 2-3, controlling their distance from the pouring surface. Inlet guide pipe flange 2-11, intermediate guide pipe flange 2-21, and outlet guide pipe flange 2-31 limit the movement of the inlet guide pipe 2-1, intermediate guide pipe 2-2, and outlet guide pipe 2-3, and guide the control rope 1-5, preventing jamming caused by changes in their positions.
[0020] In this invention, to address the difficulty of supporting the frame 1-1 on the ground at the construction site, the supporting frame 1-1 in the guide pipe control section is fixedly connected to the concrete pouring mold 3, while maintaining the accurate relative position of this invention and the concrete pouring mold 3.
[0021] In this embodiment of the invention, a pair of rope winding rollers 1-3 are coaxially mounted on the output shaft of the winch 1-2 in the guide tube control section, and the two control ropes 1-5 are wound in opposite directions on the rope winding rollers 1-3. This solves the problem of the two control ropes 1-5 moving in the same direction.
[0022] In this embodiment of the invention, a depth measuring instrument 4 is installed on the support frame 1-1 in the guide pipe control section. The position of the pouring surface obtained by the depth measuring instrument 4 is used to control the opening of the winch 1-2, thereby changing the height of the pouring surface of the outlet guide pipe 2-3.
[0023] In this invention, to address the obstruction and contamination of the concrete pouring inlet by the diversion pipe control section, a concrete inlet 5 is provided on the side of the inlet diversion pipe 2-1 in the pouring diversion pipe section.
