Mast crane control system for installation of cement waste heat boiler

Abstract

The invention provides a mast crane control system for installation of a cement waste heat boiler. The mast crane control system comprises a main hook motor M1, a variable amplitude motor M2, an oil pump M3, a first hydraulic cylinder used for controlling a mast to rotate leftwards, and a second hydraulic cylinder used for controlling the mast to rotate rightwards, wherein the oil pump M3 communicates with the first hydraulic cylinder through a first electromagnetic valve YA1, and the oil pump M3 communicates with the second hydraulic cylinder through a second electromagnetic valve YA2; and the mast crane control system for installation of the cement waste heat boiler further comprises a second contactor KM2 used for controlling the main hook motor M1 to rotate forwards, a third contactorKM3 used for controlling the main hook motor M1 to rotate reversely, a fourth contactor KM4 used for controlling the variable amplitude motor M2 to rotate forwards, a fifth contactor KM5 is used for controlling the variable amplitude motor M2 to rotate reversely, and a sixth contactor KM6 used for controlling the oil pump M3. The mast crane control system adopts a remote control switch to realizecontrol, so that workers do not need to carry out on-site transportation, safety accidents are avoided, moreover, when the mast is used for hoisting, ascending and descending limiting and variable-amplitude limiting of a main hook are achieved, the rotation limit of a rotary hydraulic cylinder is achieved, and the limits guarantee that the mast can be normally hoisted.

Description

technical field [0001] The invention relates to a crane control system for a mast used for cement waste heat boiler installation. Background technique [0002] In the existing technology, the well-known technology has been widely used in cement waste heat utilization power generation projects in my country in recent years. Waste heat power generation boiler projects are often added and modified on the basis of the original cement production line, so the kiln tail boilers are located in narrow sites. Moreover, the boiler is installed on a steel or concrete platform about 15 meters above, and generally cannot use a proper truck crane. In order to reduce the production cost, our company uses the mast hoisting method, but the mast hoisting has various unstable factors due to its high installation position and the need for multiple people to operate, which is prone to various safety production accidents. This is the weak point that existing technology exists. Contents of the in...
