[0001] The invention relates to the application field of concrete pouring, and in particular to an automatic concrete chute device and a construction method thereof. Background Art

[0002] like Figure 1 As shown, the super high-rise building includes a core tube 1 and a giant column 2. During the construction of the core tube, a self-climbing steel platform 3 is set up, and a concrete placing machine 4 is set up on the steel platform for concrete pouring. During the construction of the giant column 2, the concrete placing machine 4 is often used for concrete placing. A steel section 5 is set up inside the giant column 2, and concrete is coated outside the steel section 5. In order to facilitate the adjustment of the concrete placing position, a chute is often set up under the concrete placing pipe 6 of the concrete placing machine for concrete placing operation. The chute is adjusted manually, and the height difference between the discharge end of the chute and the concrete pouring surface is in a variable state, which is not easy to control, and is easy to cause concrete segregation, affecting the quality of the concrete structure. Summary of the invention

[0006] Furthermore, the conduit device also includes a hard pipe located above the telescopic pipe and a soft pipe located below the telescopic pipe.

[0007] Furthermore, a distance meter is provided on the intercepting device or the conduit device, and the distance meter is used to measure the height of the concrete pouring surface; The automatic concrete chute device also includes a processor, in which a height difference threshold is preset. The processor can calculate the actual height difference between the discharge port of the catheter device and the concrete pouring surface based on the measurement data of the rangefinder. The processor can control the extension and retraction of the telescopic tube to match the actual height difference with the preset height difference threshold.

[0008] Furthermore, the baffle plate on the side of the concrete containing bin facing the lower side of the chute can be opened and closed, and when opened, the concrete moves downward along the chute.

[0009] Furthermore, a slide rail is provided on the chute, and the intercepting device moves along the slide rail.

[0010] Accordingly, the present invention also provides a construction method of the automatic concrete chute device, comprising the following steps: Step 1: Install the chute, interception device and conduit device, and slide the interception device along the chute to a suitable position; Step 2: Concrete slides down from the top of the chute into the concrete storage bin of the intercepting device and is output through the conduit device; in the concrete pouring project, the length of the telescopic tube of the conduit device is controlled so that the height difference between the bottom end of the conduit device and the concrete pouring surface meets the requirements.

[0011] Furthermore, a distance meter is provided on the intercepting device or the conduit device, and the automatic concrete chute device further comprises a processor, wherein a height difference threshold is preset in the processor; In step 2, during the concrete pouring project, the length of the telescopic tube of the conduit device is controlled so that the height difference between the bottom end of the conduit device and the concrete pouring surface meets the requirements, specifically: The distance meter collects the distance information between the meter and the concrete pouring surface and transmits the distance information to the processor; The processor calculates the actual height difference between the discharge port of the conduit device and the concrete pouring surface; A height difference threshold is preset in the processor, and the actual height difference is compared with the height difference threshold. If the actual height difference exceeds the height difference threshold, the processor controls the length of the telescopic tube of the catheter device to match the actual height difference with the height difference threshold.

[0012] Due to the adoption of the above technical scheme, the present invention has the following advantages and positive effects compared with the prior art: the automatic concrete chute device can adjust the height difference between the bottom end of the conduit device and the concrete pouring surface through the telescopic tube, which can effectively avoid segregation due to excessive falling height during concrete pouring; the intercepting device can drive the conduit device to move along the chute, and can continuously adjust the position of the conduit device to discharge the material, reduce the flow distance of the concrete after falling, and avoid segregation of the concrete due to flowing; by setting a rangefinder and a processor, the telescopic tube telescopic control can be realized, so that the actual height difference matches the preset height difference threshold.

The advantages and features of the present invention will become clearer in conjunction with the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0016] Embodiment 1

[0017] Combination Figure 2 and Figure 3As shown, the concrete automatic chute device provided in this embodiment includes a chute 10, a cut-off device 20 and a conduit device 30.

The cut-off device 20 includes a concrete containing chamber 21, and the top of the conduit device 30 is connected to the concrete containing chamber. After the concrete on the chute 10 slides into the concrete containing chamber 21, it is output through the conduit device 30. The conduit device 30 includes a telescopic tube 32, and the telescopic tube 32 can adjust the length, so as to adjust the height between the bottom end of the conduit device 30 and the concrete casting surface.

[0018] The automatic concrete chute device provided in this embodiment can adjust the height difference between the bottom end of the conduit device 30 and the concrete pouring surface through the telescopic tube 32, which can effectively avoid the segregation caused by the excessive falling height during concrete pouring. In addition, during the traditional chute pouring, the chute is limited by the rotation radius when rotating, and the discharge position cannot be continuously adjusted.

The interception device 20 in this embodiment can drive the conduit device 30 to move along the chute 10, and can continuously adjust the discharge position of the conduit device 30, reduce the flow distance of the concrete after falling, and avoid the segregation of the concrete due to the flow, especially when the density of the steel bar is large.

The two ends of the telescopic device 323 are respectively connected to the first fixing ring and the second fixing ring, and the distance between the first fixing ring and the second fixing ring can be adjusted. For example, the telescopic device 323 can be a jack, an electric drive threaded rod, etc. The telescopic device drives the first fixing ring and the second fixing ring to move closer or farther, so that the bellows is stretched or compressed, thereby adjusting the actual length of the telescopic tube 32, and further controlling the height between the bottom end of the conduit device 30 and the concrete casting surface. Further, the conduit device 30 also includes a hard tube 31 located above the telescopic tube 32 and a hose 33 located below the telescopic tube 32. The hard tube 31, the telescopic tube 32 and the hose 33 are connected in sequence, and the top of the hard tube 31 is connected to the concrete containing bin 21.

[0020] In a specific embodiment, a distance meter is provided on the intercepting device 20 or the conduit device 30, and the distance meter is used to measure the height of the concrete casting surface.

[0021] In a specific embodiment, the rear end plate 22 of the concrete containing bin 21 facing the lower side of the chute 10 can be opened and closed. When opened, the concrete moves downward along the chute 10 .

[0022] In a specific embodiment, a sliding device is provided between the chute 10 and the intercepting device 20. The sliding device may be in the form of a slide rail and a running wheel, or in the form of a gear and a rack rail.
