Device for taking up and paying off cable automatically

Abstract

The invention provides a device for taking up and paying off a cable automatically. The device for taking up and paying off the cable automatically comprises a control device, a motor and a winch. The winch comprises a cable winding drum and a rotating shaft. The cable winding drum is fixed to the rotating shaft. The rotating shaft is supported on a rack. An output shaft of the motor is connected with the rotating shaft of the winch through a clutch. A braking device is further arranged on the winch. The control device is connected with the motor. The motor drives the winch to rotate, and thus the cable can be wound on the cable winding drum of the winch or unwound from the cable winding drum; in addition, the clutch is arranged between the output shaft of the motor and the rotating shaft of the winch, and thus power transmission between the motor and the rotating shaft can be cut off or recovered at any time according to the situation; and the braking device is arranged on the winch, and thus rapid braking of the winch can be achieved through the braking device. In this way, by adoption of the device for taking up and paying off the cable automatically, the cable can be taken up or paid off conveniently, the taking-up or paying-off process can be controlled, and operation is safe.

Description

technical field [0001] The invention relates to a device for automatically retracting and unwinding cables. Background technique [0002] With the development of science and technology in today's world, resources are becoming more and more important to development, and there are abundant resources in the ocean that have not been exploited. In the process of developing marine resources, people first need to survey or explore the ocean, especially An understanding of the geology and landforms of the seabed is required. [0003] When carrying out geological exploration on the seabed, it is often necessary to sample the seabed material. During the sampling operation, the operation is generally carried out on the survey ship or the offshore operation platform.

Problems solved by technology

[0003] When carrying out geological exploration on the seabed, it is often necessary to sample the seabed material. During the sampling operation, the operation is generally carried out on the survey ship or the offshore operation platform. The cable of the motor is put into the water together with the sampling frame; after the sampling motor completes the sampling on the seabed, the cables of the sampling motor and vibration motor need to be taken back together with the sampling frame; because the seawater is very deep, the cable length of the sampling motor is very long, and the The cable will also be impacted by the sea current. The cable put into the seawater will usually be stretched tightly, and the cable will be under a lot of force. At this time, if the cable is recovered to the drum on the deck, a large pulling force will be required; the previous work In the process, the cables are pulled by manpower, which is time-consuming, labor-intensive, inefficient, and the pulling force is uneven, which may cause damage to the cables and even the operators, which is dangerous to a certain extent.

Therefore, there is a need for a cable recovery device that can save time, effort, and safe operation to solve the current operational difficulties
