Description

The Multifunctional concrete delivery pump car
Technical field the utility model relates to concrete conveyance, cement injection and the sand-lime slurry conveying white washed wall that building construction is used, and the equipment of hoisting heavy and the excavation cubic metre of earth and stone, a kind of Multifunctional concrete delivery pump car.
The existing piston concrete pump of background technology and piston concrete pump car are structurally, they have all adopted the twin-tub pump structure, namely 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 that pumping efficiency is high, but the width of concrete pump truck is larger, 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.
Existing concrete pump and pump truck all are pumped commercial concretes, support the use with the concrete conveyance 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 existing concrete mixer can only be installed concrete pump pipe, can not work as crane and use, can not hoisting heavy, for example, the constructional materialss such as concrete prefabricated board, brick and reinforcing bar.
The reverse fold arm of existing concrete mixer can not be installed excavator-type shovel clamshell excavator, can not work as excavator and use, and 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, can lift by crane constructional materials, and job area is large.
The conveying rubber pipe of existing concrete pump and pump truck is all thicker, can not connect mud and smear for the white washed wall operation.
Summary of the invention is in order to overcome the limitation of existing piston concrete pump and concrete pump truck, the utility model has designed a kind of Multifunctional concrete delivery pump car, make it not only can pumped commercial concrete, the concrete that again can the pumping pony mixer stirs: after Weighting system had been installed, its reverse fold arm can hoisting heavy; At it after folding arm has been installed excavator-type shovel clamshell excavator foremost, the cubic metre of earth and stone that can also carry out long-distance large-range excavates construction: can also carry the cement paste of grouting and the mortar of white washed wall usefulness when the diameter of concrete cylinder and conveying rubber pipe diminishes, mud is smeared the operation of just can plastering wall in the connection.
