Detailed Description
In order to better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.
Referring to fig. 1, the present invention provides a horizontal dock gate winch with self-protection function, which includes a brake 2, a force measuring device 5 and a control system.
The brake 2 is arranged on a motor 1 of the dock gate winch 4, a hydraulic control parking normally-closed/driving normally-open brake is adopted, and the motor 1 drives the winding drum to rotate through a reduction gearbox 3.
The force measuring device 5 is arranged on the dock gate winch 4 and used for monitoring the load condition of the steel wire rope of the dock gate winch 4.
The control system acquires monitoring data of the force measuring device 5 and controls the actions of the motor 1 and the brake 2 according to the monitoring data.
The control system adopts Siemens 1500 series PLC, or CPU, and is responsible for collecting winch operation signals and controlling corresponding brake of winch operation, and 4-20mA current signals are output by the three-pulley force transducer to detect the stress state of the steel wire rope.
As shown in fig. 2, the hydraulic control includes a hydraulic station 6, a hydraulic pump 7, a main motor 8, an auxiliary motor, and a control valve (including a check valve, a solenoid valve, a single throttle valve, an overflow valve, etc.).
The hydraulic station 6 is connected with a hydraulic pump 7, an oil pipeline of the hydraulic pump 7 is connected with a main motor 8, an auxiliary motor and a control valve, and the control valve is connected with the brake 2.
The hydraulic station 6 is also provided with a temperature sensor 9 and a liquid level alarm 10.
And a motor cooling pump set 11 and an oil return filter 12 are arranged on an oil return pipeline of the hydraulic pump 7.
When the winch is started, the temperature sensor 9 and the liquid level alarm 10 are used for detecting that the oil temperature and the liquid level are not abnormal, the hydraulic station 6 provides hydraulic oil for the brake, the parking normally-closed brake is opened, the driving normally-open brake is in an open state at the moment, the main motor runs, and the winch works normally. When the winch stops, the hydraulic station 6 provides hydraulic oil for the brake, the normally open brake of the travelling crane is closed, the cooling motor stops, and the winch is in a temporary stop state in work.
Referring to fig. 3, when the dock gate winch 4 works normally, the motor 1 is started, then the parking normally-closed brake of the brake 2 is opened, and the dock gate winch 4 works normally to provide pulling force.
When the temporary parking is needed in the working process of the dock gate winch 4, the motor 1 is stopped, the normally-open running brake of the brake 2 is closed for braking, the dock gate winch 4 enters a temporary parking state, and the steel wire rope still has pulling force. In the parking process, when the load is greater than the given braking force, the brake 2 slips due to the fact that the external torque is greater than the braking torque of the brake 2, the whole dock gate winch 4 passively releases the steel wire rope until the tension of the steel wire rope is smaller than the given braking force, and the dock gate winch 4 brakes again.
When the dock gate winch 4 works normally, when the external load fluctuates and the external load measured by the force measuring device 5 is continuously larger than the given safe working load, the control system controls the dock gate winch 4 to perform active action, the motor 1 rotates reversely, the steel wire rope is actively discharged, the tension on the steel wire rope is reduced until the tension of the steel wire rope measured by the force measuring device 5 is smaller than the safe working load, and the dock gate winch 4 enters a working state again.
To sum up, in order to solve the problem of release load when the dock gate winch overloads, the utility model discloses the flap type dock gate winch can accurately provide brake force when equipment brakes, and dock gate winch 4 can skid the release pulling force when the external load exceeds safe load. The method specifically comprises the steps that a hydraulically-controlled parking normally-closed/normally-open brake 2 is used, when temporary braking is needed in the operation process of a dock gate winch 4, the normally-open brake is closed to brake by using oil pressure, a given braking force is provided, and when the external load on a steel wire rope is larger than the given braking force, the brake begins to slip. Because the brake is controlled by hydraulic pressure, the given brake force is irrelevant to the abrasion of the brake pad, and the given brake force can be effectively ensured for a long time. The brake disc is completely soaked in the oil, so that the abrasion of the brake disc can be effectively reduced when the brake 2 slips.
The dock gate winch 4 can monitor the load condition of the steel wire rope through the external force measuring device 5 when equipment runs, and the control system can automatically act according to the tension of the steel wire rope read by the force measuring device 5 when the external load exceeds a safe load. Specifically, when the tension of the steel wire rope measured by the measuring device 5 is larger than the safe load, the dock gate winch 4 decelerates or actively brakes, reversely releases the rope, releases the tension of the steel wire rope until the tension of the steel wire rope measured by the external force measuring device 5 returns to the safe load, and then returns to the normal working mode.
The purpose of protecting the whole system and the steel wire rope is achieved through the two modes, and the workload of daily maintenance can be effectively reduced.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
