In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the utility model provides a rotatory feed divider of big section shaft lining concrete, includes fixed spout support, is equipped with the fixed spout that inclines to the decurrent on the fixed spout support, installs rotatory hopper stand under the export of fixed spout, and rotatory hopper stand mounting has rotatable rotatory hopper, and rotatory hopper is connected with rotatory branch material spout, and rotatory branch material spout slides through rotatory spout universal wheel and sets up on the main platform.

Rotatory hopper stand welded fastening is fixed with the base in main platform central zone, and rotatory hopper stand top is fixed with the base, and base and roating seat pass through bearing rotatable coupling, and rotatory hopper is fixed on the roating seat.

The front end of the rotary material distribution chute is provided with a retractable chute.

And two sides of the main platform are provided with overturn-preventing inclined struts.

The utility model relates to a rotatory feed divider of big section vertical well lining concrete has following technological effect:

1) through setting up rotatory chute, can be so that the unloading is convenient, reduce the elephant trunk and arrange quantity, and then reduce elephant trunk dismouting engineering volume, reduce construction cost, reduce and arrange the degree of difficulty.

2) Through setting up collapsible spout, both made things convenient for normal unloading, avoided simultaneously receiving main platform border guardrail influence.

3) Through setting up fixed spout support, fixed spout, because fixed spout feed inlet sets up at the edge, consequently can directly set up the elephant trunk at the shaft lateral wall, the fixed spout of cooperation can directly the unloading, need not equipment such as bridge crane and hang a jar unloading, can realize incessant unloading, and the efficiency of putting into storage improves, and avoids hoist and mount to bring the potential safety hazard for the operation personnel on the platform.

4) The device can be dismantled fast, during the construction, can hang out or transfer into the shaft with the device in, but utilizes this device to carry out concrete placement and pressure steel pipe installation circulation and go on, guarantees engineering efficiency.

Detailed Description

As shown in figures 1-9, the rotary distributing device for lining concrete of the large-section vertical well is characterized in that the rotary distributing device is placed on a pressure steel pipe for reinforcement, backfill concrete is poured, the steel pipe is spaced from the well wall by about 1m, the height of a bin is 15m, and the rotary distributing device belongs to high-altitude operation and needs to be provided with a protective railing. The device comprises a fixed chute support 1, wherein the fixed chute support 1 is fixedly connected with a truss main beam 16 of a main platform 7 through bolts so as to be convenient for disassembly and transportation during turnover between vertical shafts; the fixed chute support 1 and the fixed chute 2 are welded into a whole. 2 slopes of fixed chute set up, the unloading of being convenient for, and be equipped with rotatory hopper stand 3 under 2 exports of fixed chute, and rotatory hopper stand 3 welded fastening is regional at main platform center, and 3 tops of rotatory hopper stand are fixed with base 15, and base 15 passes through bearing rotatable coupling with roating seat 14, and rotatory hopper 4 is fixed on roating seat 14. The rotary hopper 4 is connected with the rotary material distribution chute 5 into a whole, and the lower part of the rotary material distribution chute 5 is welded and fixed with a support with universal wheels, and 2 universal wheels are arranged. A retractable chute 10 is arranged at the front end of the rotary distribution chute 5. In order to distribute the material into the storage space, the retractable chute 10 needs to extend beyond the outer edge of the platform. Because the rotation is influenced by the railing, set up collapsible spout 10 and shrink, can make when operating more nimble and feasible.

As shown in fig. 10-11, here, the outside of the rotary material-separating chute 5 is provided with a slide rail 18, the end of the slide rail 18 is provided with a limit plate 19, and the retractable chute 10 is slidably disposed on the slide rail 18 through a pulley 20 and is limited by the limit plate 19 to avoid being separated from the rotary material-separating chute 5. Because the rotary distributing chute 5 and the retractable chute 10 are obliquely and downwards arranged, the retractable chute 10 is in an extending state under the conventional condition, so that the cloth is convenient. When meeting the railing and stopping, the retractable chute 10 is manually retracted and continuously rotated to complete normal material distribution.
