Abstract
The utility model discloses a dual-winding synchronous action control system of a hydraulic diaphragm wall grab, which comprises a grab shoulder pole beam (1) and dual-winding hydraulic oil circuits; each dual-winding hydraulic oil circuit is provided with a solenoid valve; the grab shoulder pole beam (1) is provided with an inclined sensor (2); the input end of a PLC controller is electrically connected with the inclined sensor (2), and the output end is electrically connected with the solenoid valve. The utility model is a dual-winding synchronous action control system of a hydraulic diaphragm wall grab, which lifts two main hoists of a grab crane synchronously during hoisting.
Description
Technical field
The utility model relates to a kind of double hoisting synchronization action control system, particularly relates to a kind of continuous wall hydraulic grab double hoisting synchronization action control system.
Background technology
On the continuous wall hydraulic grab hoisting crane, be to hoist to grab bucket by winding plant to carry out construction operation.And, asynchronous problem can be in the process of hoisting occurs, thereby influence work efficiency and complete machine safety is exerted an influence for the grab crane that two master winches are arranged.At present, on the continuous wall hydraulic grab hoisting crane not special arrangement two master winch hoisting systems are carried out regulating control synchronously.
The utility model content
Technical problem to be solved in the utility model provides a kind of continuous wall hydraulic grab double hoisting synchronization action control system that makes two master winches synchronization lifting in the process of hoisting of grab crane.
In order to solve the problems of the technologies described above, the continuous wall hydraulic grab double hoisting synchronization action control system that the utility model provides, comprise the grab bucket shoulder pole girder, the hydraulic circuit of double hoisting, on each hydraulic circuit of double hoisting, be respectively equipped with electromagnetic valve, be provided with inclination sensor on described grab bucket shoulder pole girder, the input end of PLC controller is electrically connected with described inclination sensor, and the mouth of described PLC controller is electrically connected with described electromagnetic valve respectively.
Adopt the continuous wall hydraulic grab double hoisting synchronization action control system of technique scheme, the inclination sensor of installing on the shoulder pole girder in grab bucket detects whether level of grab bucket shoulder pole girder, the detection signal of inclination sensor is sent into the PLC controller carry out analyzing and processing, send by the PLC controller then and adjust electric signal to electromagnetic valve, hydraulic circuit by the solenoid control double hoisting, realization is to the control of master winch, make two master winches can synchronization action, thus the final synchro control that realizes hoisting system.In the process of continuous wall grab work, the asynchronous problem if two master winch hoists can in time be adjusted hoisting system, effectively to reach synchronous mode of operation, guarantees the work safety of grab crane.
In sum, the utility model is a kind of continuous wall hydraulic grab double hoisting synchronization action control system that makes two master winches synchronization lifting in the process of hoisting of grab crane.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, on each hydraulic circuit of double hoisting, be respectively equipped with electromagnetic valve, on grab bucket shoulder pole girder 1, be provided with inclination sensor 2, the input end of PLC controller is electrically connected with inclination sensor 2, and the mouth of PLC controller is electrically connected with electromagnetic valve respectively.
Referring to Fig. 1, the inclination sensor of installing on grab bucket shoulder pole girder 12 detects whether level of grab bucket shoulder pole girder 1, the detection signal of inclination sensor 2 is sent into the PLC controller carry out analyzing and processing, send by the PLC controller then and adjust electric signal to electromagnetic valve, hydraulic circuit by the solenoid control double hoisting, realization is to the control of master winch, makes two master winches can synchronization action, thus the final synchro control that realizes hoisting system.
Referring to Fig. 1, in the process of continuous wall grab work, if inclination sensor 2 detects grab bucket shoulder pole girder 1 when being higher than another side on one side, the PLC controller is controlled the opening of the electromagnetic valve on its hydraulic circuit, in time hoisting system is adjusted, make both sides reach balance,, guarantee the work safety of grab crane effectively to reach synchronous mode of operation.
