Description

Technical Field:

In the slip form construction of high-rise buildings standing on the ground or underground vertical shafts, the slip form construction technology is preferentially adopted. During the slip form construction process, the concrete feeding method and the uniformity of concrete paving are related to the success or failure of the slip form construction. If the paving thickness of the concrete is uneven, it is easy to cause strength deviation when the concrete comes out of the form. If the concrete comes out of the form too early, it will still have fluidity and plasticity, resulting in collapse and even causing the instability of the slip form. If the concrete comes out of the form too late, it will stick to the form, causing damage to the concrete or the slip form equipment. Content of the Utility Model:

The rotary distributor 1 includes a feeding hopper 2, a vertical shaft 3, an outer shell 4, and a bearing 14. The bottom of the outer shell 4 is rigidly connected to the working platform of the distribution platform 11. A base 6 is welded to the bottom of the outer shell 4. The base 6 is made of steel plates. A triangular rib plate 5 is welded between the base 6 and the outer shell 4. The bottom of the base 6 is welded to the working platform of the distribution platform 11. A bearing 14 is installed inside the outer shell 4. The vertical shaft 3 is inserted into the bearing 14. The feeding hopper 2 is made of thin steel plates and rolled into a conical funnel shape. The feeding hopper 2 is located at the top of the vertical shaft 3. The feeding hopper 2 and the vertical shaft 3 are welded together as a whole. A feeding nozzle 8 and a handle 7 are provided on the side of the feeding hopper 2. The feeding nozzle 8 and the handle 7 are welded on the corresponding two sides of the feeding hopper 2. The feeding nozzle 8 and the handle 7 are on a straight line. The feeding nozzle 8 communicates with the feeding hopper 2 and is obliquely installed on the lower side of the feeding hopper 2.
