Concrete spreader

Abstract

The invention provides a concrete spreader which is flexible, portable and convenient. The concrete spreader comprises a base, an upper supporting seat, an arm support assembly hinged with the upper supporting seat and a concrete conveying pipeline, wherein the arm support assembly comprises a master arm support and at least one section of slave arm support; the master arm support is hinged with the upper supporting seat; a lifting mechanism capable of lifting the master arm support in a vertical plane relative to the upper supporting seat is arranged between the master arm support and the upper supporting seat; the master arm support is hinged with all sections of slave arm supports sequentially; a lifting mechanism capable of rolling up and expanding two sections of slave arm supports or expanding and unfolding two sections of slave arm supports is arranged between every two sections of slave arm supports; the lifting mechanism between every two sections of slave arm supports comprises a crank connecting rod mechanism positioned on the opposite inner sides of the two sections of slave arm supports when the slave arm supports are folded; a plurality of sections of concrete conveying pipelines are provided and fixed relative to the sections of slave arm supports; and the sections of pipelines are connected with one another in a rotary closed manner. The concrete spreader has the beneficial effect that the whole structure is simple and stable; the concrete distribution position is quickly and sensitively adjusted; a connection mechanism among the arm supports is flexible and firm; and the space is saved; and the service life of the concrete spreader is long.

Description

technical field [0001] The invention belongs to the manufacturing field of concrete engineering machinery and equipment, and in particular relates to a concrete distributing machine for transporting concrete to a position to be poured. Background technique [0002] At present, all the concrete construction equipment with long booms are generally only suitable for large-scale construction sites and large-scale construction units due to their bulky size and high cost. Generally, small and small-scale construction units still use manpower or The original method used tower cranes to lift and transport, which was time-consuming and labor-intensive and the quality of the project could not be guaranteed. With the development of urban construction, the use of equipment for the transformation of some original urban villages was greatly limited by the equipment. This towed concrete placing machine can solve the problem of the construction site and some relatively small construction un...
