Description
Technical Field
The invention relates to the technical field of breaking and dismantling machines, in particular to an electronic control system and method of a sorting type breaking and dismantling machine.
Background
The demolition of the waste buildings is carried out by using explosive directional blasting or manpower in the past, which is very dangerous, easy to cause accidents and basically forbidden in foreign countries. China is also beginning to be restricted. Various effective breaking and dismantling machines are developed to solve the breaking and dismantling problem in the urban and industrial development process, and the movable breaking and dismantling machine has good maneuvering characteristics and can be more and more widely applied. With the continuous deepening of the urbanization process in China, a large number of old buildings need to be dismantled. The movable type breaking and dismantling machine utilizes hydraulic power provided by a diesel engine to drive an impact drill bit, can carry out efficient destruction and dismantling operation on a reinforced concrete structure, compares with traditional manual dismantling, and greatly improves the working efficiency. Compared with blasting type demolition, the mobile demolition machine is more flexible in work, and particularly in urban areas with dense population, the safety of the mobile demolition machine is more obvious. The movable type breaking-in machine basically duplicates the mature platform technology of the excavator in the aspects of a core power system, movable carrier drive control, turntable-drive control and arm and breaking-in machine head position control by using the technology of a large number of excavators. Only an impact control system of the breaking-in machine head is needed to be added. Fig. 1 is a basic structure diagram of a conventional mobile demolition machine.
On the other hand, although the conventional mobile demolition machine can efficiently demolish reinforced concrete structures, masonry structures and the like, the existence of reinforcing steel bars often causes the phenomenon of 'coupling broken wires' in the demolished building residual soil. That is, the broken loose cement blocks are connected together by reinforcing bars, and a large number of reinforcing bars remain in the concrete structure. The residual waste steel bars still have higher economic value, so that a new requirement is put forward for the traditional mobile breaking and dismantling machine in the process of dismantling the modern building, namely, the residual waste steel bars in the residual soil of the building are sorted and collected. At present, the common mode of the industry is to crush a reinforced concrete structure by using a movable type breaking and dismantling machine and then sort, select and collect the reinforced concrete structure by using a manual assistance mode. This undoubtedly greatly increases the manual work intensity, reduces the work efficiency, and has safety problems at the same time.
