HOISTING STEEL WIRE ROPE AUTOMATIC TENSIONING CONTROL SYSTEM AND DIAPHRAGM WALL GRAB BUCKET MACHINE

摘要

Provided are a hoisting steel wire rope automatic tensioning control system and a diaphragm wall grab bucket machine. The control system comprises: a motor (1), provided with an oil port A and an oil port B; a hydraulic pump I (4), provided with an oil port P1 and an oil port T1; a control valve I (2), provided with an oil port A', an oil port B', an oil port a, a signal input end I3, an oil port P and an oil port T; a hydraulic pump II (9), provided with an oil port P2 and an oil port T2; a control valve II (8), provided with a signal input end Y1, an oil port A'' and an oil port P3; a collector, used for collecting working state data of a host machine; and a controller (10), provided with a signal input end I1 and a signal output end O1, wherein the control valve I (2) is further provided with an oil port a. According to the hoisting steel wire rope automatic tensioning control system and the diaphragm wall grab bucket machine, in the process of grasping soil using two grab bucket segments, a hoisting system is capable of automatically correcting a grab bucket body in time to control the degree of inclination of the grab bucket body within a rational range, and the accuracy of grooving is effectively ensured. The correction process can be completed by means of manual control, and can also be completed by means of automatic control, thus improving the system reliability, reducing the labor intensity, and lowering the skill requirement.
