Device for conveying concrete on building tower crane

Abstract

The invention discloses a device for conveying concrete on a building tower crane. The device for conveying concrete on the building tower crane comprises an L-shaped pipe, wherein a rubber pipe is arranged on the surface of the L-shaped pipe in a sleeved manner; a holding mechanism is fixedly arranged at the top of the L-shaped pipe; a first flange is fixedly arranged at the top end of the L-shaped pipe; the top end of the first flange is fixedly connected with the bottom end of a first press disc through a bolt; the first press disc is connected with the bottom end of a swinging mechanism ina clamping manner; and the top end of the swinging mechanism is connected with a second press disc in a clamping manner. The device for conveying concrete on the building tower crane has the following beneficial effects: by arranging a rubber sleeve on the surface of a holding ring in a sleeved manner, and arranging a plurality of anti-slide particles on the surface of the rubber sleeve, a good anti-slide effect is achieved, constructors are facilitated to hold the L-shaped pipe through the holding ring, and the L-shaped pipe cannot be separated from the hands of the constructors easily; andmeanwhile, the constructors are facilitated to swing a discharge end of the L-shaped pipe to a pouring point, and the holding ring is connected with the L-shaped pipe through four connection rods, sothat the firmness of the holding ring is improved.

Description

technical field [0001] The invention relates to a device for conveying concrete, in particular to a device for conveying concrete on a building tower crane, and belongs to the technical field of building construction. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion from cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. After uniform mixing, it is densely formed and maintained. It is a kind of artificial stone made by hardening. In the process of pouring concrete, it is often necessary to fix the delivery pipe on the tower crane, and the concrete is delivered to the inside of the formwork through the delivery pipe. It is convenient for construction personnel to support the bottom of the conveying pipe. The conveying pipe is easy to fall off from the hands of the construction personnel, and it is difficult for the constructi...
