Vehicle mounted concrete transfer pump

Abstract

The invention relates to a vehicle-mounted concrete conveying pump, which comprises a swing oil cylinder, a hydraulic oil tank, a conveying cylinder, a washing room, a main oil cylinder, an oil pump, and an engine to form a vehicle-mounted pump hydraulic system, and the vehicle-mounted pump hydraulic system and electrical control system are mechanically and reliably connected to the chassis. , the whole machine moves freely with the speed of the chassis such as a car, and its characteristics are as follows: 1) An independent engine is used to directly drive the oil pump of the hydraulic system; an adjustable throttle valve is set in the oil circuit, and a swing system with constant pressure is used; 2) The electrical control system can be set freely Programmable controller; 3) In addition to connecting the high and low pressure switching valves between the rod chamber and the rodless chamber of the two master cylinders, a logic valve, an electromagnetic pilot valve and a shuttle valve are also connected between the rodless chambers of the two master cylinders. The present invention adopts the integrated design of machine, electricity and hydraulic, adopts programmable controller in the electric, cancels complicated hydraulic control, thereby reduces the weight of the whole machine, reduces the failure rate of the whole machine, and prolongs the trouble-free working time , and increase the pumping capacity index to 500-600MPa m 3 , so that the whole machine meets the changes in the current construction market, and the application prospect is very broad.

Description

Technical field: [0001] The invention relates to a concrete delivery pump, in particular to a vehicle-mounted concrete delivery pump. It is mainly used in various industrial and civil construction projects such as industrial equipment foundations, water conservancy, dams, harbors, tunnels, bridges, high-rise buildings, etc., where the demand for concrete is large and the quality is high. Background technique: [0002] In recent years, my country's construction market has undergone great changes. As far as high-rise buildings are concerned, the number of floors has increased from dozens of floors to today's eighty or ninety floors, and the construction time of each floor has been shortened from the original 7-8 days to 4-5 days. , which requires pumping equipment to adapt to changes in the market. Technical requirements for new products: ①Mechatronic-hydraulic integrated design; ②Power matching adapted to the market; ③Innovative layout of pumping system. The product increase...

AI Technical Summary

Problems solved by technology

The disadvantage is that the concrete outlet pressure is low, and the pumping height is limited by the height of the boom

At present, the highest placing boom at home and abroad is only about 50m, so its vertical pumping height is also limited to about 50m
