Description

The invention relates to the field of construction and repair of railway tracks, in particular to devices for welding rails.

From the description of the published application WO 2019/128014 dated 07/04/2019 according to class. E01B 31/18 known self-propelled track machine for welding rails, containing a platform frame mounted on running trolleys with a stationary module with power equipment attached to it and a retractable body with technological equipment placed on it with the possibility of longitudinal movement, the frame of which rests on a support unit with a jack and is equipped with outriggers.

When reaching the section of the track where it is necessary to carry out welding work on butt welding of rails, the outriggers are lowered onto the track and the track machine, moving self-propelled, leaves from under the retractable body. This creates a track area covered by a retractable body for welding work. Based on the largest number of similar features, this device is accepted as a prototype.

In the known device it is impossible to lower the retractable body onto the track, because the side walls of the body prevent it from lowering. For this reason, complete isolation of the welding site from the effects of external weather conditions is not achieved.

The technical objective of the invention is to ensure that in the working position of the retractable body it can be lowered until the welding area is completely covered from the influence of external weather conditions.

To achieve this technical result in a track machine for welding rails, containing a platform frame mounted on running trolleys with a stationary module with power equipment attached to it and a retractable body with technological equipment placed on it with the possibility of longitudinal movement, the frame of which rests on a support unit with a jack and is equipped with outriggers, unlike the prototype, in the area of the support unit with a jack, a free opening is formed between the platform frame and the frame of the retractable body or the lower trim of the side walls, which makes it possible to lower it in the working position of the retractable body until the welding area is completely blocked from the influence of external influences weather conditions.

In addition, the support unit with the jack is installed along the longitudinal axis of symmetry of the platform and is equipped with a thrust bearing and a trolley that can move along the longitudinal guides of the platform. The internal compartment of the retractable body, adjacent to the central support unit, is equipped with transverse walls and a floor on which the technological equipment is located. Rollers are installed on the side beams of the platform frame, on which the lower frame of the side walls of the retractable body rests. The track machine is equipped with latches for the retractable body on the platform frame in the transport and working positions, and folding wheel supports are fixed at the end wall of the retractable body and in the area of the internal compartment.

This design of the device allows you to completely block the working area from the influence of weather conditions, which will greatly facilitate compliance with technological requirements for the welding process.

This technical solution is illustrated by drawings, where: Fig. 1 shows a side view of the track machine (the front side walls of the stationary module and the retractable body are not shown); in fig. 2 - supporting frame of the retractable body; in fig. 3 shows a side view of the support assembly; in fig. Figure 4 shows the support unit, view from the end of the track machine; in fig. 5 shows the initial stage of body extension; in fig. 6 shows an intermediate stage of the body extension process; in fig. 7 shows the position of the body after it is fully extended; in fig. 8 - position of the retractable body after it is lowered onto the track; in fig. 9 shows the hanging of the retractable body on wheel supports for maneuvering without lifting; in fig. 10 shows the folding wheel supports in working position; in fig. Figure 11 shows the latch of the retractable body on the frame of the track machine platform.

A track machine for welding rails contains a platform frame 1 supported by two running bogies 2 and 3 with a drive on one axis for maneuvering in operating mode. A stationary module 4 with a diesel generator set 5 and a control cabinet 6 is fixed to the frame 1, and a support unit 7 with a jack is installed. Auxiliary equipment is built into the frame 1 of the platform: pumping station 8, battery box 9, compressor 10, fuel tank 11. Behind the stationary module 4 along the length of the platform there is a retractable body 12 with a supporting frame 13, which, after lowering onto the track, forms a welding shop for welding rails along the way, where a certain temperature is maintained.

The retractable body 12 has an internal compartment 14 for placing stationary and portable equipment, outriggers 15, folding wheel supports 16, a ventilation system 17, side walls of the working area 18, a welding device 19, a lifting device 20 for moving and positioning the welding device 19.

In the area of the support unit 7, between the frame 1 of the platform and the frame 13 of the retractable body 12 or the lower frame of the side walls 18, a free opening is formed, which makes it possible to lower it in the working position of the retractable body 12 until the welding area is completely covered from the influence of external weather conditions. The presence of side walls 18 of reduced height in this area is not necessary, because the internal compartment 14 of the retractable body 12, adjacent to the support unit 7, is equipped with transverse walls 21 and a floor 22, on which the technological equipment is located.

The support unit 7 with a jack is installed along the longitudinal axis of symmetry of the platform and is equipped with a thrust bearing 23 and a trolley 24, which can move along the longitudinal guides 25 of the platform. The thrust bearing 23 allows the retractable body 12 to rotate relative to the platform frame when it is guided into the working area in curved sections of the track. The supporting frame 13 has a protruding part in which a fastening 26 is provided for the support unit 7.

Rollers 27 are installed on the side beams of the platform frame 1, on which the lower trim of the side walls 18 of the retractable body 12 rests.

There is no floor between the compartment 14 and the rear end wall 28 in the working area. The rear end wall 28 is equipped with a doorway.

The track machine is equipped with latches for the retractable body on the platform frame in the transport and working positions. On the frame 1 there is a limiter 29 for extending the body 12 and its lock 30 in the working position.

To fix the retractable body 12 on the frame 1 in the transport position, a locking device 31 is used, from which a pin 32 is pushed out under the action of a spring. The pin 32 enters the hole of the bracket 33 mounted on the frame 1. The locking device 31 is fixed to the rear end wall 28 of the retractable body 12 When moving the retractable body 12 into the working position, first lower the outriggers 15, and then turn off the locking device 31. Air is supplied to the locking device 31, which presses on the finger 32, pushing it inside the locking device 31. The finger 32 comes out of the hole in the bracket 33 , after which you can begin to extend the body 12.

The supporting frame of the rear end wall 28 has a transverse crossbar 34, to which folding wheel supports 16 are attached through hydraulic cylinders 35, which lower them into the working position and raise them into the transport position. In the front part of the sliding body 12 there is a similar device. After the folding wheel supports 16 are activated, the outriggers 15 are moved into the transport position, the retractable body 12 rests on the folding wheel supports 16, and the entire track machine can move to a new place of work. To prevent the movement of the retractable body 12 by inertia towards the frame 1 and the occurrence of an emergency, a lock 30 is provided on the frame 1, which prevents the support unit 7 from moving along its guides 25.

Retractable body 12 is equipped with emergency exits, external and internal lighting.

Upon arrival at the work site, the track machine is positioned so that the area to be repaired is underneath it. First, the outriggers 15 of the rear end wall 28 of the retractable body 12 are lowered (Fig. 5), then, using a running trolley 2 with a drive on one axle, the track machine begins to move out from under the retractable body 12. On the main frame 1 there are rollers 27, along which the retractable body 12 rolls, the support unit 7 moves along its guides 25. When the wall 21 reaches the edge of the frame 1, the internal outriggers 15 (Fig. 6), located near the wall 21, are lowered, after which the track machine continues to move out from under the retractable body 12, until the support unit 7 reaches the limiter 29. When the support unit 7 reaches the limiter 29 (Fig. 8), the retractable body 12 is lowered onto the path (Fig. 8). At the same time, the welding area is completely isolated from the influence of external weather conditions, making it easier to comply with technological requirements for the rail welding process.

This device can be manufactured at a machine-building plant using existing structural materials, technologies and components.
