Description

The object of the solution is to drive a gyrolanger flywheel, which uses a variable speed variator to adjust the torque transmission parameters between the winch and the flywheel. The device is used mainly in forestry gyrolants and wherever it is necessary to accumulate excess energy generated during operation of the device.

BACKGROUND OF THE INVENTION

Previously known cable transport equipment for the transport of goods does not utilize energy recovery for their operation. The gravitational energy of the truck and load is wasted in thermal energy braking systems. Braking systems are usually designed as drum, disc and belt. During operation, they become intensely heated and worn, and therefore the brakes are also used. Retarder brakes are most often realized as aerodynamic brakes. eddy current electric.

Further, a solution according to patent application PP no. 108-2007, Industrial Property Office of the Slovak Republic, entitled Mechanical recovery cable device with flywheel - gyrolanovka. It uses a flywheel to store the truck's gravitational energy and cargo in the downhill approach. The adaptation of the flywheel operation mode to the winch operation mode according to this solution is realized by means of an electric transmission consisting of an electric voltage generator and an electric motor. The disadvantage of this solution in comparison with the proposed solution according to the present application is lower efficiency and higher weight of the device.

The essence of the technical solution

The above-mentioned drawbacks of the hitherto known constructions of the rope approach equipment in heavy and steep inaccessible terrain are overcome by a mechanical regenerative rope device with a mechatronic flywheel drive by means of a variator.

The essence of the solution is that the storing of the energy into the accumulator flywheel as well as the removal of the energy from the flywheel is carried out by means of a multi-stage variator with a continuously variable transmission ratio.

During the gravity approach of the load down the slope, the retractor with the tow rope is released. Due to the gravitational energy of the truck and the load, the tow rope is unwound and the drum on which the tow rope is wound is turned. The torque from the drum is transmitted to the variator, which allows a smooth change of the gear ratio. The transmission ratio is set by the control unit based on the data from the flywheel, drum and rope carriage speed sensors. The control unit controls the operation of the variator, brake system and clutches so that the approach speed is maintained at the desired value. The control circuit acquires the actual speed of the truck from the pull-wire speed sensor. The drum brake system is activated when the desired truck speed is exceeded and the maximum gear ratio is set on the variator, or when the flywheel speed has reached the maximum permissible value.

The method of propulsion in the gravity approach phase down the slope is that the gravitational energy of the truck and the load causes the pulling rope to be unwound from the drum. The rotary motion from the drum is transmitted via the variator to the flywheel. The variator provides the required number of revolutions and the necessary torque for the flywheel to spin. The mechanical flywheel accumulates the gravitational energy of the load truck and transforms it into kinetic energy. The mechanical flywheel is housed in a vacuum housing to prevent overheating and loss of energy due to air friction.

In the phase of pulling the empty trolley back up the slope, the reverse gear is first set on the auxiliary transmission and the retractor with the tow rope is released. Subsequently, torque is applied from the flywheel via the auxiliary transmission to the variator and then to the drum with the wound tow rope. Engaging the reverse gear in the auxiliary transmission will cause the drum to rotate in this mode the opposite of the gravity approach phase. The control unit adjusts the gear ratio on the variator so that the speed of pulling the empty trolley back into the stand has the desired course. It uses data from the drum, flywheel speed sensors and the actual speed of the carriage on the carrier rope.

The method of propulsion in the empty car pull-out phase consists in using the energy accumulated in the flywheel to wind the tow rope to the winding device, which is transferred to the drum via a variator controlled from an electronic control system. The reversing direction of the drum is changed by means of an additional reversing gearbox.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 schematically illustrates the construction of a gyrolanger flywheel drive according to the solution.

EXAMPLES

In FIG. 1 shows a gyrolancer flywheel drive according to a solution comprising a winding device 1 provided with a braking system 5. The winding device 1 is connected via a clutch 6 to a variator 3. The variator 3 is connected via a reverse gear 4 and a clutch 7 to a flywheel 2. equipped with brake system 8 and clutch 9.

The operation of the gyrolanger flywheel drive is controlled by the electronic control system 12 The control system 12 processes signals from the flywheel speed sensor 10, the winding speed sensor 15 and the pulling speed sensor 14. It controls the variation of the gear ratio 3, clutch operation 6, 7, 9 , brake 5.8 and reduction gear 4.

In the gravity approach weight down the slope, the gravitational energy of the load causes unwinding of the rope JT from the winding device L The rotary movement of the winding device 1 is transmitted to the variator 3 after clutch 6 is engaged. 12 on the basis of the data of the speed sensor 10 of the flywheel 2 and the speed sensor 15 of the winding device 1 so that the winding speed of the towing rope 11 sensed by the sensor 14 has the desired course. In this way, the gravitational energy of the load truck is accumulated in the mechanical flywheel 2.

At the end of the gravity approach of the load down the slope, the clutches 7 and 9 are disconnected to prevent loss of flywheel 2 energy. This mode of operation of the device allows long-term storage of accumulated energy.

During the pulling phase of the empty trolley back up the slope, the speed from the flywheel 2 is transmitted via the clutch 7 to the reversing gear 4. The reversing gear 4 changes the speed. A change in the sense of speed is necessary for the winding device 1 to rotate in the opposite direction to that of the gravity approach phase and to wind the rope 11 onto the winding device 1. The output of the reversing gearbox 4 is connected to the input of the variator 3. The gear ratio of the variator 3 is set by the electronic control system 12 based on the data of the flywheel speed sensor 10 and the winding speed sensor 15 so that course. The output of the variator 3 is connected via a clutch 6 to a winding device 1 which pulls an empty trolley up the slope through the rope 1T.

The energy stored in the flywheel 2 can also be used to pull the load from the side under the carrier rope on which the cable car moves. In this mode of operation, the truck must first be fixed to the carrier using the brake. The further operation of the flywheel drive device is then similar to that in the empty carriage withdrawal phase.

The energy stored in the flywheel can also be used to power the power supply, hydraulic and pneumatic circuits of the gyrolanger, for example: an electric generator for powering the electronic control system 12, a starter of an internal combustion engine, a hydraulic generator and the like. To this end, the output A serves to which torque is supplied from the flywheel 2 via the clutch 9.

The brake 8 serves to reduce the speed of the flywheel 2 and the flywheel. to stop its rotation. In case of exceeding the max. the permitted speed of the flywheel 2, in the emergency stop mode, or after the cableway has finished working before it is transported to another working position.

The advantage of the mechatronic flywheel drive 2 according to the solution lies in its low weight. It accumulates the gravitational energy of the load carriage in the flywheel 2 with high efficiency. This accumulated energy with high efficiency returns to the working process. It significantly saves fuel consumption and the environment.

The mechatronic flywheel drive 2 according to the solution is intended primarily for driving gyrolanovka for approaching wood mass after tree felling in difficult and inaccessible terrains, on steep slopes, respectively. for gravity transport of various costs in the field of agriculture and construction with a difference in height.

The method of driving the flywheel 2 according to the solution has a wide application especially in the field of forestry, agriculture and construction and wherever it is necessary to bring the load down the slopes. However, these options do not limit the scope of application of the subject matter. Other possibilities of use in the means of transport are possible, e.g. for accumulating and recovering braking energy.
