Description

Work train for welding and styling

The utility model relates to the field of construction and repair of railways.

Known working train for welding and laying of rail tracks, including sequentially located: platform for transporting rail lashes with a device for securing lashes on the rear platform; a car with a diesel generator; welding machine type PRSM-2; cover platform with anti-edge device; a platform with a device for unloading lashes and a traction mechanism with a grip (crane type UK-25/9); movable support and trolley for moving lashes (1).

The disadvantage of such a working train is that it does not provide the full range of work necessary to ensure a high-quality weld according to technical conditions, since there are no devices for dressing, grinding and heat treatment of the welded joint. To provide some types of these works, additional reconfigurable devices are used.

The development of a utility model is based on the task of developing a working train that would provide a set of works necessary to ensure high-quality welded joints. In addition, such a train will allow carrying out the whole complex of work in the field, regardless of weather conditions.

The problem is solved in that in the proposed working train for welding and stacking rail lashes, including sequentially located rear platform for transporting rail lashes with a mechanism for securing rail lashes, a car with a diesel generator, a platform with a device for unloading lashes, and

MPKE01V 29/16 29/05 rail tracks

a welding machine, a traction mechanism with a gripper, anti-edge devices, it is new that it is equipped with two platforms located on both sides of the car with a diesel generator and equipped with roller bearings, on the first with a gradual increase in their height to the level of the anti-edge device located in a car with a diesel generator, and on the second, respectively, with a gradual decrease, on the rear platform for transporting rail lashes, a traction mechanism is installed in front of the mechanism for securing the rail lashes m with a gripper, and behind the fastening mechanism - a sliding mechanism, in a car with a diesel generator with the ability to move along the anti-dimming device, a cutting device, a welding machine, a hydraulic dressing device, a heat treatment unit and two grinding machines are arranged sequentially along the train, and a platform with a device for unloading lashes, made in the form of a ramp, is equipped with an anti-edge device.

6 is a platform with a device for unloading lashes.

The working train 1 contains a rear platform 2 for transporting rail lashes, on which a traction mechanism 3 (in the form of a winch) with a gripper 4, a fixing mechanism for 5 rail lashes and a sliding mechanism 6 are installed; a platform 7 with roller bearings 8 and reflectors 9, and the roller bearings 8 are made with a gradual increase in their height to the level of the anti-dimming device 10 located in the car 11 with a diesel generator 12. In the car 11, in the sequence along the train, with the possibility of moving along the anti-dangling device 10 installed

detachable device 13 (type RA-1), welding machine 14 (type K-920), hydraulic dressing device 15, installation 16 for heat treatment and two grinding machines 17.18 (type ШПШ and С4РА). All devices in the car run from a diesel generator 12. The working train also contains a platform 19 with roller bearings 20, made with a gradual decrease in their height from the level of the anti-edge device 10 to the level of the anti-edge device 21 of the platform 22, at the end of which there is a device 23 for unloading lashes executed in the form of a ramp. Behind platform 22, a cover platform (not shown) is installed that serves to support the ramp in the transport position.

The device operates as follows.

Rail lashes are loaded onto platforms for transportation and secured using the fastening mechanism 5 on the rear platform 2. Work train 1 is transported to the site to the rail lash unloading site, where the cover platform is rolled back and the ramp 23 designed to unload the lash is lowered. Before starting work, one rail lash is fastened, the grip 4 is fixed, the diesel generator 12 is turned on, and the lash 3 is pulled by the traction mechanism to the platform 7, which is designed to raise the lash rollers 8 to a height to the level of the anti-edge device 10. Guides are installed to orient the lashes to the middle of the platform 7 reflectors 9. Next, the lash is pulled onto the anti-edge device 10, which serves to hold the lash in a straight state along the length of the car 11, passes along the roller bearings 20 of the platform 19, is intended to smoothly lower the height of the lash to the level of the anti-edge device 22 of the platform 21. The lash is pulled into the track along the ramp 23 until the second end of the lash is on the platform 7 in the area of the sliding mechanism 6. After that, the second lash is loosened, it is shifted to the first whip and connect the pads. Work train 1, moving, pulls the connected lashes until the joint

will be in the zone of the cutting device 13. In this section, a segment of the ends of the rail lashes with bolt holes occurs. Next, the lash is moved to the area of the welding machine 14, where the joint is welded. The welded joint is moved to the area of the hydraulic dressing device 15, where it is edited after welding. Then the welded joint is subjected to heat treatment at the installation 16 for heat treatment and cleaned with grinding machines 17 and 18. The welded rail lash is pulled by the working train until the end of the second lash is in the zone of the sliding mechanism 6. The cycle of work is repeated until the required number of rail lashes is unloaded. At the end of the installation process, all equipment is brought into transport position.

The proposed working train will allow to carry out the whole cycle of work comprehensively and regardless of weather conditions, since all operations are carried out indoors, which ensures high-quality connection of lashes with a simultaneous reduction in the time for these works.
