Description

The utility model relates to lifting and traction devices and can be used in industries where it is necessary to move goods in space, and is intended primarily for lowering / lifting bottom stations.

PM No. 213391 "Electromagnetic mooring device" is known from the field of technology, which is a bow automatic winch with drums, which is equipped with automation that allows you to read data: on the load of tractive effort; length of the etched cable; rope etching speed.

The developed device has the ability to maintain a constant load of cable tension; has the ability to automatically etch the cable when the set load is exceeded.

From the patent for invention No. 2760798 it is known "Launching device for small-sized uninhabited underwater vehicles and lowered sonar antennas from a carrier vessel".

Launcher for small-sized uninhabited underwater vehicles from the carrier vessel, contains a U-frame mounted on hinges in the aft part of the deck of the carrier vessel perpendicular to its diametrical plane, and the U-frame is equipped with drives and a pulley, which is located on its upper part, as well as a winch installed in the diametrical plane of the carrier vessel and equipped with an electric drive, a tensioner and a cable layer. The winch drum is equipped with a cable-rope, which is connected through a system of pulleys to an uninhabited underwater vehicle.

An automated winch with dynamic control of parameters is known, which contains a frame with a lower part and an upper console, traction wheels associated with drives are installed on the lower part of the frame, and guide rollers are installed on the upper console, while a cable is laid on the traction wheels and guide rollers (see application RU 99119331 A, published on January 27, 2001, https://yandex.ru/patents/doc/RU99119331A_20010727).

The disadvantages of the known device are the difficulty of hooking the cable and the need to either break the cable or thread it through the opening of the device, which increases the time of these operations.

The technical problem is to eliminate the noted shortcomings.

The technical result consists in increasing the reliability of the device during the descent/ascent of bottom stations.

The problem is solved and the technical result is achieved by the fact that an automated winch with dynamic control of parameters contains a frame with a lower part and an upper console, traction wheels connected with drives are installed on the lower part of the frame, and input and output guide rollers are installed on the upper console, while on traction wheels and guide rollers a cable is laid, while, according to the utility model, three traction wheels are installed on the lower part of the frame, two outer wheels are located at a greater distance from the upper console than the third wheel located between the outer wheels, each wheel is equipped with a separate drive and sensor rotation, and the guide rollers are equipped with strain gauges connected to the winch control system with the ability to transmit data on the load on the rollers to ensure the required output characteristics of the equipment by redistributing the load between the traction wheel drives without stopping the equipment.

The winch contains a number of traction wheels with wedge surfaces that form friction pairs with the rope, due to which a reliable self-locking of the cable / halyard / rope is carried out. Each traction wheel is driven by a separate drive (motor-reducer). Traction wheels are placed in such a way that the rope covers their working surface as efficiently as possible. Also, the design of the traction wheels provides for the possibility of their readjustment for working with ropes with a diameter of 6 mm to 12 mm, which expands the scope of its application in industry. The input and output guide rollers are equipped with strain gauges that register the cable tension both at the entrance and at the exit of the automated winch. They allow in the process of pulling the rope to control and maintain at the proper level the force developed on the traction wheels. The dynamic characteristics of the rotation of the traction wheels are controlled by rotation sensors (encoders) and allow for adaptive control of an automated winch with dynamic control of parameters.

The utility model is illustrated with the help of drawings.

In FIG. 1 shows a general front view;

in fig. 2 - general view from behind;

in fig. 5 - right side view.

The device contains a frame 1 with drives (motor-reducers) 2 installed on it, traction wheels 3 and an upper console 4 with guide rollers 5. The rotation of the drives 2 is controlled by a group of rotation sensors (encoders) 6. The traction force at the input and output of the automated winch is controlled strain gauge sensors 7. Maintaining the specified modes of operation of the automated winch is carried out by dynamically controlling the speed and power of drives 2 based on data received from rotation sensors 6 and strain gauges 7.

The automated winch works as follows:

The cable in the state of tension is tucked into the groove of the first guide roller 5, pulled through the bottom of the first traction wheel 3, then through the top of the second traction wheel 3, then through the bottom of the third traction wheel 3 and passed through the groove of the second guide roller 5. In this case, the guide rollers 5 are located on the upper console 4, and the traction wheels 3 are located on the lower part of the frame 1.

Each of the three drives 2 drives its own traction wheel 3, with which it has a direct mechanical connection. From the rotation of the traction wheels 3, the movement of the cable begins, which, in turn, transfers the rotation to the guide rollers 5. In this way, the cable can move through the automated winch in the direction of winding or unwinding.

A sensor 6 is located on the output shaft of the drive 2, which registers the angle of rotation and transmits the results to the control controller. Thanks to the wedge surface of the traction wheels 3, a stable traction force is also maintained on the cable. Rotation sensors 6 are fixed on the bottom of the frame 1.

Each guide roller 5 is equipped with a strain gauge 7, which registers the degree of cable tension and transmits the results to the control controller. Thus, the load on the cable at the entrance and exit of the automated winch is determined.

When the traction wheels rotate, the cable is securely captured by wedge-shaped clutches, providing traction at the input of the automated winch. All power loads that occur during the operation of the automated winch are assumed by frame 1. Control and maintenance of the power and dynamic performance of the automated winch is carried out using the control controller.

The claimed utility model is used as follows.

The automated winch is designed for tripping during seismic surveys in the water areas in the transit zone and on land areas adjacent to the studied water areas, in particular, to search for deep hydrocarbons, as well as for monitoring and engineering work. The device securely fixes a smooth cable, with a diameter of 8 mm to 12 mm, without the need for additional adjustment. The traction wheels of an automated winch have the effect of self-tightening, that is, with an increase in the traction load on the cable, the force of holding the cable from slipping also increases. Also, the automated winch is able to work not only in the forward, but also in the reverse direction.

To put the device into operation, you must:

1. Lead the cable into the automated winch, laying it in the grooves of the guide rollers and traction wheels in a certain sequence.

2. Provide cable preload on the guide rollers of the automated winch.

The device is intended for pulling a cable/rope/rope with maintaining the required level of power/drawing speed during seismic exploration in water areas, in the transit zone and on land areas adjacent to the water areas under study, in particular, to search for deep hydrocarbons, as well as for monitoring and engineering work. The automated winch is able to provide reliable/stable operation with a smooth cable/halyard/rope with a diameter of 8 mm to 12 mm, without the need for additional technological operations and the constant presence of the operator in the immediate work area.

The design also involves working with a cable / halyard / rope with knots tied on it, installed carabiners and other compact rigging devices used for splicing cables / halyards / ropes.

Thus, with simple operations, a quick laying of the cable/halyard/rope into the guide rollers and traction wheels is ensured without auxiliary operations and additional time costs, which ensures the reliability of the device in the process of preparing for the lowering/raising of bottom stations. The safety of personnel is also ensured, because near the automated winch, the constant presence of the operator is not required.
