Anti-decoupling concrete stringing device that can change direction

Abstract

The invention discloses an unhooking-prevention direction changeable concrete tumbling barrel device, belonging to the concrete pouring construction special-purpose device. The unhooking-prevention direction changeable concrete tumbling barrel device comprises a tumbling barrel main body, an unhooking-prevention device and a traction device; the tumbling barrel main body comprises a plurality of barrel bodies which are successively stacked top-to-end; the upper part and the lower part of the two sides of the barrel body are fixedly provided with sealing hanging rings; the sealing hanging rings on the lower part of the barrel body are movably connected to the sealing hanging rings on the upper part of a lower adjacent barrel body through a unhooking-prevention device; and the middle part of the barrel body is provided with a hanging ring; and hanging ring is connected to the hanging ring traction device steel wire through a steel wire. The unhooking-prevention direction changeable concrete tumbling barrel device solves defects of the traditional concrete tumbling barrel that the unhooking is easy and direction changing is difficult. Besides, the unhooking-prevention direction changeable concrete tumbling barrel device is simple in structure, easy in use, safe and practical, and can dramatically improve working efficiency.

Description

technical field [0001] The invention relates to a stringing tube used in concrete pouring in the field of building construction, in particular to a concrete stringing device capable of preventing decoupling and changing direction, which belongs to special equipment for concrete pouring construction. Background technique [0002] With the development of large-scale engineering construction, it is often necessary to pour large concrete structural parts, but when the free fall height of concrete exceeds 2 meters, segregation will occur, resulting in poor appearance of concrete structural parts, sand grains, exposed aggregates, Reinforcement exposure and other phenomena, and the concrete strength is greatly reduced, which seriously affects the bearing capacity of concrete structural parts. Therefore, the poured concrete for pile foundations exceeding 2 meters must be transported to the construction field by conduits, stringers or chutes. [0003] The string tube refers to the tu...
