Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pouring technology, specifically to a vibratory concrete pouring device. Background Technology
[0002] Currently, in concrete pouring construction, concrete is typically transported to the pouring location via a tremie pipe, and then manually vibrated using an immersion vibrator to eliminate air bubbles. This method suffers from several drawbacks, including low efficiency of manual vibration, especially in large-volume concrete or densely reinforced areas where vibration is difficult; delayed vibration can lead to concrete segregation and poor compaction, affecting pouring quality; and the fixed tremie pipe outlet position makes it difficult to adapt to multi-angle pouring requirements under complex conditions. Furthermore, when using the enlarged area method to pour concrete at the bottom of slabs, it is difficult to ensure the compactness of the concrete inside the excavated cavity in the latitudinal direction.
[0003] Therefore, there is an urgent need for a new type of conduit device that can simultaneously deliver and vibrate concrete, and whose pouring position can be flexibly adjusted. Utility Model Content

[0027] This embodiment of a vibratory concrete pouring device includes,
[0028] The main body of the conduit consists of a standard section conduit 1 and a vibratory working section conduit 5 at the end;
[0029] The built-in vibrator has a vibrator shaft 3 located at the central axis of the guide tube body. Its head is equipped with a spiral blade 4. The vibrator body 7 is located in the lower half. The spiral blade 4 rotates in the same direction as the concrete flow.
[0030] Universal joint interface 8, located at the end of the conduit body, is used to connect the robotic arm 9;
[0031] The discharge port 10, shaped like a trumpet, is located at the end of the guide tube 5 in the vibrating working section.
[0032] The conduit body adopts a segmented design. The ordinary section conduit 1 uses a high-pressure resistant rubber hose, while the vibratory working section conduit 5 uses a stainless steel hose. The two sections are connected by a flange on the bearing seat 2. A pressure sensor is installed on the inner wall 6 of the conduit body, located at the starting point of the vibratory working section conduit 5, and is welded to the inner wall 6. The bearing seat 2 includes an inlet bearing seat and an end bearing seat, which respectively connect the ordinary section conduit 1 to the vibratory working section conduit 5 and the vibratory working section conduit 5 to the outlet 10. The built-in vibrator body 7 has a chrome-plated surface, and the head spiral blade 4 rotates clockwise, consistent with the concrete flow direction, and is fixed to the inner wall 6 of the conduit body by the vibrator shaft 3. The spiral blade 4 has an appropriate pitch and rounded edges, and is welded to the inner wall 6 of the conduit body. The universal joint interface 8 is a spherical structure, including a ball welded to the end of the conduit and a ball socket connecting to the robotic arm 9, with an angle range of ±90° vertically and ±180° horizontally. The outlet 10 is flared and connected to the flange on the end bearing seat.

[0034] At the same time, the concrete delivery pump is started and the built-in vibrator 7 is turned on; the angle of the guide tube is adjusted by the robotic arm 9 so that the discharge port 10 is aligned with the pouring position; the concrete flows evenly into the pouring area under the pushing and vibration of the spiral blades 4; after the pouring is completed, the power source is turned off, the guide tube is disassembled for cleaning, and finally the efficient operation of simultaneous pouring and vibration of concrete is achieved.
