Abstract

A multifunctional concrete pump truck comprises a concrete pumping system, a swing foldable arm system, a counterweight system, a stirring and feeding system and a travelling chassis. The multifunctional concrete pump truck not only can pump ready-mixed concrete, and concrete which is stirred by a small-sized agitator, but also can be used as a foldable arm crane to lift heavy objects such as building materials; and the concrete pump truck can be used as a high-front shovel and a wall plastering machine, so the truck is multi-functional. The equipment performance and the construction efficiency are improved, and the truck can used in the construction process of middle-rise and low-rise buildings in villages and cities, and also can be used in other engineering.

Description

Multifunctional concrete is carried pump truck

Technical field the utility model relates to transmission and concrete transmission, cement injection and the sand-lime slurry conveying white washed wall that building construction is used, and the equipment of the hoisting heavy and the excavation cubic metre of earth and stone, and a kind of multifunctional concrete is carried pump truck.

Background technology existing piston formula concrete pump and piston concrete pump car are structurally, they have all adopted the twin-tub pump structure, just there are two hydraulic jacks to drive two concrete cylinders, a hydraulic jack and a concrete cylinder are one group of pumping systems, and two groups of pumping systems are arranged side by side, and export concrete valve and are S type valve, its advantage is the pumping efficiency height, but the width of concrete pump truck is bigger, be not suitable for using in the place in less space, and cost is higher.

I have designed a kind of triplet commutation rotary valve in " multifunctional concrete delivery pump " patent (patent No. ZL201020609959.2), through using, also some deficiency is improved in this application.

Available coagulation soil delivery pump and pump truck all are the pumping commercial concretes, with the supporting use of transmission and concrete transmission tank car, can not pumping construction unit the concrete that stirs of mixer because the hopper of concrete pump truck is all higher, the discharging opening that is higher than mixer is not installed again and is stirred feeding system.

The reverse fold arm of available coagulation soil pump truck can only be installed the concrete pump line, can not work as the crane use, can not hoisting heavy, for example, constructional materialss such as concrete prefabricated board, brick and reinforcing bar.

The reverse fold arm of available coagulation soil pump truck can not be installed excavator-type shovel clamshell excavator, and can not work as excavator and use,

The arm of existing excavator is all shorter, for the long-distance large-range construction, often needs several excavators to work simultaneously.

The tower crane that building operations is used because balancing weight has been installed, make it can lift by crane constructional materials, and job area is big.
