47-meter r-type foldable arm rack concrete pump truck and a producing method thereof

Abstract

The invention relates to a 47-meter R-type foldable arm rack concrete pump truck and a producing method thereof. The 47-meter R-type foldable arm rack concrete pump truck comprises an arm rack system,a power system, a pump sending system, an electric system and a hydraulic system. The 47-meter R-type foldable arm rack concrete pump truck is characterized in that the hydraulic system is provided with a hydraulic element used for checking actual workload transmission, a main oil pump is a variable inclined-disc type axial plunger piston pump, the hydraulic system uses a closed loop, a five-section rolling foldable arm rack is in fulcrum-type R-shaped fold, support legs are JJ-shaped double-swinging telescopic support legs, and a main oil cylinder is of a guiding-sleeve piston-rod sealing structure. The arm-rack system of the product of the invention is controlled by an electric-proportion multi-path valve and remotely controlled by a wireless remote control system. The arm rack oil cylinder has a bidirectional interlock function, effectively guarantees the work safety and the reliability of the arm rack and enables the intelligence of the whole system to be higher. The elements independently work and are not mutually interfered. The product of the invention has the characteristics of energy saving, high effect and low intelligence and worker labor intensity, and can be widely used in the projects of city building, bridges, foundation construction, and the like.

Description

technical field [0001] The invention relates to a boom pump, and in particular discloses a concrete boom pump truck with a fulcrum-type "R" type folding boom and a pumping vertical height of 47 meters and a manufacturing method thereof. The pump truck of the invention can simultaneously Complete on-site concrete conveying and distributing operations, it has the characteristics of good pumping performance, large distributing range, self-propelled, flexible and convenient transfer. In foundation, multi-storey building construction and frequent transfer of construction sites, the use of 47-meter concrete pump truck can show its superiority, and the construction is convenient. The concrete pouring position can be changed arbitrarily within the range of boom movement, and there is no need to temporarily lay pipes on site. , can save laying time and improve work efficiency. It is especially suitable for projects with large demand for concrete pouring, super large volume and super t...

AI Technical Summary

Problems solved by technology

The pump trucks on the market generally have 3-section booms and 4-section booms. The pumping height is limited, the working range is small, and the pumping volume is insufficient, which affects the work efficiency.
