Description

Vertical downward concrete conveying device

Technical Field

The utility model relates to a building construction equipment field, concretely relates to vertical conveyor downwards of concrete for underground works construction.

Background

During underground engineering construction, the problem that concrete needs to be transported vertically and downwards is often faced, and the problems of high cost, easiness in pipe blockage and time and labor waste in disassembly due to the adoption of a pumping scheme when a conventional foundation pit is shallow are solved; the inclined chute is adopted for conveying, so that the problem that concrete is easy to separate exists; the problems of high requirement on hoisting equipment and low efficiency exist when the hopper hoisting scheme is adopted. Particularly, when the concrete needs to be continuously conveyed, in order to fully utilize the gravity action of the concrete, the pipeline transportation method is the primary choice of each construction unit.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a device that concrete is vertical to be carried downwards makes its continuous transportation that can be suitable for concrete among the underground works construction, solves the problem that the concrete quality that proposes among the above-mentioned background art is uncontrolled, conveying cost is high, increases lifting device.

In order to achieve the above object, the utility model provides a following technical scheme:

a device for vertically and downwardly conveying concrete is provided with a storage bin for temporarily storing finished concrete; the storage bin is provided with a slope of 20% -30%; the bottom of the slope is provided with a gate; the storage bin is communicated with the vertical ash sliding pipe through an obliquely arranged chute; a funnel is arranged at the top of the vertical ash sliding pipe; the vertical ash sliding pipe is also provided with an adjusting pipe connected with the outlet of the hopper; the adjusting pipe is vertically suspended through two steel wire ropes; the lower end of the adjusting pipe is inserted into a standard ash chute; and a buffer is arranged at the bottom of the standard ash sliding pipe.

The chute is formed by welding steel plates with the thickness of 6mm, the depth of the chute is 30-40cm, and the width of the chute is 40-50 cm.

The funnel sets up to circular or oval, and the built-in one deck side aperture is 5 cm's screen cloth for super grain size thing in the screening concrete plays the key role in the aspect of preventing that super grain size from causing stifled pipe.

The outlet of the funnel is inserted into the adjusting pipe by adopting a wedge-shaped steel pipe opening and is connected with the adjusting pipe;

the adjusting pipe is made of a seamless steel pipe with the diameter of 133 x 5mm, the length of a single section is 9m, an upper opening is connected with the funnel, and a lower opening is inserted into the standard ash chute;

the standard ash sliding pipe is made of a seamless steel pipe with the diameter of 159 x 6mm, is vertically suspended through two steel wire ropes, and is connected with the upper port and the lower port through flange plates and bolts.

The buffer is made into an N shape by welding two 159 × 6mm seamless steel pipes side by side, the upper end of the buffer is connected with the ash chute by a flange, and the lower end of the buffer is connected with a hose or a chute to be used as a concrete discharge hole.

The utility model provides a vertical device of carrying downwards of concrete is applicable to deep basal pit, big square quantity in the pit, continuous concrete construction, and main well head storage silo, chute, vertical swift current ash pipe, concrete buffer form one set of perpendicular transportation system, have with low costs, efficient, can ensure the characteristics of concrete quality.
