Description

MULTI DRUM WINCH WITH MULTI LAYER STRUCTURE}

The present invention relates to a multi-drum multi-winch, in particular the function of the 1-power source, 1-drum type winch to apply the same to a plurality of drums to perform the role of concentrating a plurality of winches, each drum The present invention relates to a multi-drum winch having a multi-layer structure in which various wires including a signal cable, a rope, and the like are uniformly wound, and a plurality of drums are all driven or only some drums are selectively driven.

Generally, various types of winches are used for winding cables using power, but most of them are operated by driving one drum with one power. In case of separating and winding several strands of cable, the conventional technology can be used by using multiple winches or by dividing or replacing drums, but the cost of securing a winch in the heat, selective driving restriction, and inefficient problems due to drum replacement are caused. In addition, when the diameter of the cable to be wound changes, the width of the level winder is fixed, there is a problem that the cable does not pass.

For example, the installation of multiple sensors and cables on the sea floor and the recovery of all signal cables under special conditions of receiving signals is a very labor intensive and time-consuming task, especially depending on the gentle personnel or windlass (or capstan). Is not an easy task to recover hundreds of signal lines and organize them for reuse. In this case, if only one winch for the number of signal lines can be easily solved, the work can be easily performed, but excessive cost is required, as well as problems such as occupying a large operating space and reducing work efficiency.

Thus, there has been a need for a single winch development that can integrate multiple winch functions.

Disclosure of Invention The present invention has been made to solve the above-mentioned problems and defects, and an object of the present invention is to provide a multi-drum multi-winch capable of selectively driving multiple drums using a single power source.

In addition, another object of the present invention is to not only naturally pass through the level winder even when the diameter of the wire is not uniform, such as when the diameter changes instantaneously, such as a connection part connected to the middle part of the wire. To provide a multi-drum multi-chamber winch that can be easily inserted or peeled off the sea wire.

In order to achieve the above object, the present invention is a multi-drum multi-winch of the present invention has the same function as a 1-power source, 1-drum type winch to a plurality (for example 6) drum By applying, it plays a role of concentrating a plurality of winches, and each drum is equipped with a level winder, a brake, etc. to uniformly wind various wires including a signal cable, a rope, and the like. Deceleration (eg about 10: 1) allowed the power to be transferred in a chained manner.

In the case of the level winder, the lead screw applied the existing technology, but the inlet of the cable can be opened and closed, which is adapted to the cable diameter so that different diameters can pass through such as a connection part connected using a connector. Invented in shape.

The X-shaped structure of this level winder allows the cable to be loosened and retracted by the spring-loading method in a range of twice the normal diameter, which is very useful for winding cables of varying diameters in cases where precise winding is not required. Have

In addition, the drive means for driving the drum is configured to drive the drum shaft by reducing the driving force of the motor (V.S Motor) capable of speed control to the reducer. One side of the main body has a main control panel having an electric / electronic control function and a wired remote controller for controlling the operation of the electric motor as a power source, so that functions such as loosening, winding, speed control, and emergency stop can be arbitrarily controlled.

The rotary shafts of the upper and lower drums rotate at the same speed, and for example, all the drums may be driven by using clutches installed on six drums, or some drums may be selectively driven. In this case, a brake device is attached to prevent unwanted drum idle.

In such winch operation, the winding speed can be arbitrarily adjusted using the power control rotary switch from the standstill to the maximum speed (0 ~ 2m / sec), and the emergency stop switch is attached for safety. .

In addition, the power on / off, forward and reverse operation, speed control and periodic functions are all available from the main control panel and the wired controller.

The screw rod of the level winder and the lead screw causes the pitch of the screw rod to move by the diameter of the wire every one revolution of the drum, and the rotation rate of the screw rod is the same as the rotation rate of the drum shaft, but does not operate when the clutch is separated. If is connected, the screw rod is also operated.

The upper opening and closing and the X-shaped inlet width adjusting device of the wire diameter adaptation method may naturally pass even when the diameter of the wire is not uniform, such as when the diameter is changed instantaneously, such as a connection part connected to the middle part of the wire. In addition, it is very useful to easily open and close the upper horizontal wire guide roller and peel off the wire if necessary.

The level winder has four vertical wire guide rollers coupled to the X-shaped lever when the diameter of the wire is instantaneously thickened, and can be tightened using spring restoring force, for example, twice the normal wire diameter. The width varies until, and the pass width can be fixed if necessary.

Such a device has the effect that the direction of movement of the wire guide is changed after the wire (cable) is naturally wrapped on both ends of the drum, but when the transverse force is changed in the middle of the drum, a slight irregular winding phenomenon occurs. Occurs. Therefore, it is determined that the error due to the relaxation of the spring is acceptable, or in the case where a precise winding is not necessary.

More specifically, the multi-drum multi-window winch according to the present invention has a plurality of drums rotatably coupled via a bearing to a plurality of shafts rotatably coupled to the main body in multiple layers, and at the input end of the shaft of each layer. An input element to be coupled, drive means for driving the shaft of each layer, a clutch for connecting and disconnecting power between the input element and each drum, and for guiding the wires to be evenly wound and drawn out smoothly between the drums And a spring pressurized upper opening / closing X-shaped level winder and a brake for stopping each of the drums.

In addition, the level winder is guided by the guide rod by the rotation of the screw rod (less screw) connected to the shaft and the transmission member, the lever is rotated in the X-shape on the shaft fixed to the middle of the lower surface of the winder frame to move left and right A vertical wire guide roller is rotatably coupled to each of the vertical support shafts, which are coupled to each other, and fixed to both ends of the levers, respectively, and a shaft bolt having a butterfly handle is coupled to a lower side of the winder frame.
