Description

The utility model relates to rail transport, in particular, to devices for cleaning products, mainly wheelsets of rolling stock for 1520 mm gauge during repair.

A device for cleaning the wheelset of a carriage is known. It contains a wheel pair rotation mechanism, including a rotation drive, metal cleaning brushes. Moreover, the device further comprises a mechanism for supplying the wheelset to the processing zone, a mechanism for stopping the rotation of the wheelset. The wheel pair feed mechanism includes movable tool holders used to orient the wheel pair installation, mounted on the upper outer side of the body frame, supports for basing the wheel pair by means of wheel axles, a support beam, a drive. The support beam moves along the guides and interacts with the wheelset. The drive is designed to lift the support beam together with the wheelset. Cleaning tools are interconnected with the mechanism of active cleaning of the axis of the wheelset and with the mechanisms of passive cleaning of the side surfaces of the wheels. The active cleaning mechanism consists of a drive and rotation units of the cleaning tools. Cleaning tools are made in the form of cylindrical brushes and nodes reciprocating movement of the brushes along the axis of the wheelset. Mechanisms for passive cleaning of the side surfaces of the disks of each wheel are installed with the possibility of adjusting their position on the side surfaces of the disk of each wheel and consist of profile brushes, drives for moving them to ensure the interaction of the brushes with the side surfaces of the wheel disks and the removal of brushes, knots for providing the swinging movement of the brushes for shaking off products cleaning the wheelset. The drive of the rotation mechanism is connected with drive elements interacting with the wheels and transmitting rotation around the axis to them, the stop mechanism of rotation of the wheelset consists of drives designed for supplying and removing brake pads interacting with the wheels. The device provides simultaneous cleaning of all surfaces of the wheelset and improving the quality of cleaning [1].

Known automated complex for washing wheelsets. The complex includes: a chamber for washing wheelsets, wheel feed devices

pairs (at the input and output of the camera); washing solution preparation system (tank with a built-in coil for steam supply, high pressure pump); washing solution regeneration system; automatic control system. The complex is designed for washing wheelsets with a hot washing solution with a temperature of up to 90 ° C and a pressure of up to 1.7 MPa. With simultaneous mechanical cleaning of the axis and discs with rotating brushes. A walk-through type washing chamber with two rising doors consists of upper and lower parts. The lower part of the chamber serves to collect the solution flowing down during washing. In the roof of the chamber there is a hole in which the camera is connected to exhaust ventilation. The tank is equipped with a coil for heating the washing solution. Cleaning the axle and wheelset wheels is carried out by rotating brushes, which are recruited from the brush wheels. The efforts of pressing the brushes to the disks and the wheelset axis are regulated by changing the air pressure in the corresponding cavity of the pneumatic cylinder using a pressure regulator. The upper brush assembly is designed to clean the wheelset wheels on both sides and is located in the upper part of the chamber. With the help of a pneumatic cylinder, it rises to feed the wheelset into the washing chamber. The top brush assembly is a vertically arranged plate on which two pairs of drive brushes are fixed. Each pair is located on both sides of the corresponding wheel pair and is driven by electric motors. Brushes are reversed (alternately changing the direction of rotation) and scanned (vertical movement). The brushes are pressed against the surface of the wheel disks by pneumatic cylinders with adjustable force. With the same pneumatic cylinders, the brushes are moved apart to allow the washed pair to pass to the exit or to accept a new one. The design of the upper brushes is made in such a way as to ensure a constant position of the brushes relative to the disk profile of the wheelset regardless of the diameter of the wheelset (amount of wear). To do this, in the working position, the upper brush assembly with the help of a roller support rests on the central part of the axis of the wheel pair and, thus, occupies a constant position, regardless of the size of the diameter of the wheel pair. The upper brushes in different pairs, designed to clean the inside of the discs, rotate in opposite directions. The node of the upper brushes has factory settings that ensure the cleaning of wheelset wheels in the diameter range of 850 ... 950 mm. The bottom brush assembly is designed to clean the axle

wheelset. It is installed inside the lower part of the camera on the frame of the drive wheel rotation. The weight of the lower brushes is compensated by counterweights, and their pressure against the axis of the wheelset is provided by a pneumatic cylinder. The clamping force to the axis is controlled by changing the air pressure using a pressure regulator. The wheel pair rotation drive consists of an electric motor, a belt drive and a two-stage cylindrical gearbox. Rotation is transmitted to two of the four support rollers on which a pair of wheels is located inside the chamber. Two other support rollers are mounted on levers connected by a common axis, which can be rotated by a pneumatic cylinder and, thereby, push the wheelset out of the chamber after washing. The chamber is equipped with 24 nozzles of the washing unit with a diameter of 3.5 mm. Nozzles of three different types are installed: compact with a cylindrical stream and a small scattering angle, fan with a flat stream, and flare with a conical stream. Adjustable nozzles are sent from the desired wash zone. They are directed into the contact zone of the brushes with the surface being cleaned. The washing solution preparation system consists of a sectional tank with a built-in coil for supplying steam, a high pressure pump with a back-up pump. Water accumulated in the chamber pan after washing the wheelset flows by gravity into the sectional tank, which is installed below the floor level. Dirty water after washing the wheelset enters the first section of the tank, from the first to the second, in which a level gauge is installed and an overflow hole is made. The second section is separated from the third partition, the upper edge of which is higher than the liquid level in the tank (at the level of the overflow hole), and the lower does not reach the bottom of the tank. Floating suspensions accumulate on the surface of the first and second sections and must be removed from time to time. In the third section, a pipe system is installed for supplying steam to heat the washing solution to a predetermined temperature. Near the nozzle for supplying heated water to the inlet of the low-pressure pump, a direct-acting temperature regulator sensor is installed. The system of regeneration of the washing solution through the use of a hydrocyclone cleans the circulating solution of mechanical suspensions. A special pump delivers dirty water with suspensions from the first section of the tank to the hydrocyclone. And after the hydrocyclone, it merges into the first section of the tank. The thickened precipitate is discharged from the hydrocyclone into a trolley mounted under the hydrocyclone. The surface layer of the solution from the truck returns to the first section of the tank. [2]. The disadvantage of this design is the use in

her nodes brush cleaning, which are wearing and contaminating elements.

The closest in technical essence is a machine for cleaning products. It is intended for cleaning predominantly wheelsets of rolling stock during their repair. The machine comprises a washing chamber with a mechanism for rotating the wheel pairs and a washing element disposed therein, a tank and a pump for supplying washing liquid. The washing element is made in the form of at least two rotary heads with rigidly mounted swinging pipelines with nozzle nozzles located at the free ends of each pipeline. Each pivoting head consists of a housing in which a thrust cup with an earring is mounted for connection with the rotation mechanism of the washing element. The washing element is made in the form of mounted in the housing with the possibility of reciprocating movement of a three-position stepped rod. The stem is spring loaded from opposite sides. The housing of the rotation mechanism through the valve is connected to the oil flow regulator [3]. The disadvantage of this design is the complexity and unreliability of the design of the washing elements, the non-aimed direction of the jets of the washing liquid.

The aim of the invention is to simplify the design, increase the cleaning efficiency of hard-to-reach products of complex configuration and reliability of the device, as well as use a system of effective cleaning of the washing liquid, allowing it to be reused in the technological process of cleaning the wheelset.

This goal is achieved by the fact that there is a targeted effect of hot cleaning fluid under high pressure on the wheelset using hydraulic monitors. All surfaces of the wheelset, which is based on supports, are exposed to cleaning at the same time, providing access to the cleaning jets. The device uses a chamber closed with a protective casing to clean the wheelset, in which all the cleaning products remain and fall into the sump located at the bottom of this chamber. The effectiveness of the influence of the washing liquid with the help of hydraulic monitors allows you to abandon the use of mechanical cleaning elements that are wearing and contaminated to the design.

A device for cleaning wheelsets contains a chamber for washing wheelsets 1, which is closed by a protective casing 2. In the lower part of the chamber there is a sump 3, which serves to collect the detergent that flows during the cleaning process. A device for basing a 4-wheel pair inside the chamber 1 is a drive roller 5 and 6, on which a pair of wheels is mounted inside the chamber, one of the rollers is the drive 5, and the second roller is the reference 6. The wheel pair is fed to the cleaning zone using manipulators , which are captures 8 of the axis of the wheelset, driven by drives 7 and 16. Above the washing chamber there is a tank for washing liquid 10 with a pump 11, which are part of a multi-stage system for the regeneration of a washing solution - a cleaning station and circulating water 12, Inside the chamber there are fixed washing elements made in the form of hydromonitors 9, which direct the washing jet to any cleaning zone of the wheelset 13. The direction of the washing jets from the hydromonitors 9 is automatically set by the program of the control unit 14 from the console 18. The washing liquid is hot water supplied under high pressure. The device is mounted on vibration mounts 17.

The device operates in automatic mode, providing loading of the wheelset into the washing chamber by one of the manipulators with grippers, its washing and cleaning, unloading of the wheelset from the chamber by another manipulator with grippers. Before starting work, the operator sets the necessary temperature of the washing solution and the duration of the washing process, depending on the degree of contamination of the wheelset. After moving the protective casing 2, the washing chamber 1 opens, the dirty wheelset 13 is loaded into the washing chamber 1 by means of the gripper 8 of the manipulator 4, and its basing device 4. After the wheelset is installed, the protective casing 2 closes the chamber 1, and the cleaning mechanism starts to work in automatic mode . Start up

electric motors of the drives of the high pressure pumps 11 and the drive of rotation of the wheelset 15. Hydromonitors 9 aim the jets of cleaning liquid on the cleaning areas of the wheelsets 13, feeding them in the right direction for a certain time in accordance with a given program. After the set washing time has elapsed, all electric motors are switched off. On the indicator of the remote 18 displays a message about the end of the cleaning process. The protective casing 2 of the chamber 1 rises, the manipulator with grabs 8 unloads the washed wheelset 13 from the chamber 1. The washing cycle is completed and the device is ready to receive the next dirty wheelset.

The technical result of the use of this invention is the reliability and simplification of the design of the cleaning elements. This is achieved through the use of elements that are not in direct contact with the wheelset and are not contaminated. Good cleaning of hard-to-reach places of the wheelset is ensured by targeted hit of the washing solution under high pressure and the necessary time of its impact on the surface being cleaned. Saving of the washing liquid occurs due to the use of a multi-stage system of effective cleaning of the washing liquid, which allows its multiple use in the technological process of washing the wheelset. Installing the device on vibration mounts allows you not to build a massive foundation for it. The use of the drive wheels — drive and support wheelsets in the design of the device for basing the wheelset — makes it possible to wash wheelsets of various designs and sizes, making it universal. Installing a tank with washing liquid as part of a water treatment station above the washing chamber can significantly reduce the area occupied by the device.
