Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art while following the advantages of the jib-type concrete delivery pump, that is, when the length of the boom exceeds 40 meters, the working stability is poor, and the whole boom will vibrate. And solve the problem of oil inlet and air suction of the oil pump when the working speed is increased

Embodiment Construction

[0030] HDL5250THBIS-37 and HDL5350THBIS-43 boom type concrete delivery pump are two kinds of product models of the present invention. The product belongs to the mechatronic mechanical equipment in the complete set of optical, mechanical and electrical integrated equipment. It is mainly used in industrial equipment foundations with large demand for concrete and high quality requirements, water conservancy, dams, harbors, tunnels, bridges, middle and low-rise buildings, etc. A variety of industrial and civil construction projects. Its working principle is to drive the hydraulic oil pump through the mechanical connection of the engine to convert chemical energy into hydraulic pressure energy. The hydraulic oil pump is connected to various hydraulic valves through pipelines to convert hydraulic pressure energy into mechanical energy. The directional valve is used to form an automatic control closed-loop circuit through the above-mentioned components, and the concrete can be poured...

Abstract

The cantilever crane type concrete transmission pump consists of chassis, pumping system and distributing rods. It features the chassis, which is made by Nissan Isuzu Co., Ltd., reaches to European's II exhaust standard and has highest running speed of 90 km/hr for fast reaching the site; the distributing rods in two section arm double cylinder support structure and with load sensing technology adopted; and the hydraulic pumping system operating in double pump cocurrent technology. The present invention has high distributing rod stability, high hydraulic pump rotation speed and no air sucking trouble.

Description

1. Technical field: [0001] The invention relates to a concrete delivery pump, in particular to a boom-type concrete delivery pump, which is mainly used in various industries such as industrial equipment infrastructure construction, water conservancy dams, bridges, high-rise buildings, etc., which require large amounts of concrete and high quality requirements. Civil construction works. 2. Background technology: [0002] In recent years, my country's construction market has undergone great changes, the construction time has been greatly shortened, and the construction efficiency has been doubled, which requires pumping equipment to adapt to market changes. At present, concrete pumps at home and abroad are roughly divided into three categories. One is the towed concrete delivery pump, which can be dragged by a general truck, and the driving speed is about 12km / h. The advantage of this type of delivery pump is that it can pump high-rise buildings, and the vertical pumping con...
