Embodiment Construction

[0035] In terms of its structure and performance, a 22-meter "RZ" folding boom concrete pump truck of the present invention is mainly divided into five parts: a boom system, a piping system, a pumping system, a hydraulic system and an electrical system.

[0036] The oil pump of the boom hydraulic system of the present invention adopts an axial plunger pump with variable load sensing, which can automatically adjust the inclination angle of the swash plate according to the actual working load of the boom to meet the actual flow rate of the boom and reduce the hydraulic pressure of the upper part of the hydraulic system. fever. Only when the piping system is used as a vehicle-mounted pump, the piping is laid on site, and the concrete can be transported for a long distance through the high and low pressure switching of the system. The electrical system adopts PLC programmable control system, and the wireless remote control device of the human-machine interface, which makes the ope...

Abstract

The invention provides a 22-meter RZ type folding arm support concrete pump truck. The concrete pump truck comprises an arm support system, a power system, a pumping system, an electrical system and ahydraulic system, wherein the hydraulic system is provided with a hydraulic element for detecting actual workload; a main oil pump is a variable oblique tray type axial plunger pump; and the hydraulic system uses an open circuit. The concrete pump truck is characterized in that: the three-section folding arm support adopts the pivotal RZ type folding; and a front support leg is a JJ type telescopic support leg, and a back support leg is a fixing type vertical oil cylinder; the main oil cylinder adopts a guide sleeve piston rod sealing structure; the arm support system adopts the electronic proportional multi-way valve and the wireless remote control system control; the arm support oil cylinder has a directional interlocking function; and all elements can work independently without interfering with one another. The concrete pump truck has the advantages of pretty good mobility, the integration of running and pumping, high utilization ratio of equipment, small occupied space, low cost,and high pumping height; moreover, when the concrete pump truck is used for the construction of multi storied buildings, pipes do not need to be laid, so that the concrete pump truck can be quickly and conveniently used.

Description

technical field [0001] The invention relates to a boom pump, and in particular discloses a concrete boom with a fulcrum type "RZ" type folding, a vertical height of 22 meters, a horizontal pipe layout of 800 meters and a vertical height of 230 meters. pump truck. The pump truck of the present invention can complete the conveying and distributing operations of concrete on site at one time, and has the characteristics of good pumping performance, large distributing range, self-propelled, flexible maneuverability, convenient transfer and the like. The product of the invention can not only be used as a boom pump, but also has all the functions of a vehicle-mounted pump. Background technique [0002] At present, concrete pump truck pumping technology is used in the concrete construction of national key construction projects, and its application range has been widely used in water conservancy, hydropower, subways, bridges, large foundations, high-rise buildings and civil building...
