Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filling machine that simultaneously fills ballast under sleepers, levels and straightens tracks, or sprays ballast.
Concerning track treatment machines such as leveling and tamping machines.

The actual track processing machines used for such operations are satisfactory and the accuracy and quality of their work meet the requirements of the railway network.

However, in order to move from station to station or from station to site, these track processing machines must be able to run on their own at a speed of 80 Km/h, or be towed by a regular train and run at a speed of 1100 Km/h. .

Therefore, these track processing machines must be constructed in accordance with the structural standards of ordinary train vehicles.

Because of these limitations, manufacturers must equip track processing machines with bodies, rotating mechanisms, brakes, etc. that are particularly compatible with the above standards and the type of track processing to be performed.

It goes without saying that such a construction is very expensive.

This is because the price of these special equipment has an extremely large influence on the price of the orbit processing machine itself.

And the smaller the orbit processing machine is, for example in the case of a lightweight filling machine, the greater this influence becomes.

There are problems that manufacturers are actually trying to solve.

15-16) Two solutions have been proposed that can be applied to orbital processing machines weighing 15-16 or less.

One method is to mount the track processing machine on a regular train freight car and move it.

The other method is to mount the track processing machine on a special trailer connected to a tractor, for example, and move it on the road.

These two solutions do not require any special equipment on the track handling machine, but they cannot be applied to track handling machines of 16 tons or more, and in the case of the first solution, it is not necessary to provide special equipment for the track handling machine. Another solution requires specialized equipment to transfer track handling machines from road to rail (and vice versa).

Furthermore, such transshipments are rarely carried out at intermediate locations, but rather at the nearest station, which requires automated or towed small transfer means to be able to move on track within the time allotted for transshipment. Transfer is requested.

Therefore, according to the present invention, a track processing machine includes two rotating supports that move on a track and are located at a constant interval, and a track processing unit that is disposed between the two rotating supports by a support frame. In the method of manufacturing a car body, a standard freight car is at least partially cut between its two rotating supports, the two car parts and a cut part are formed between them, and a support frame is attached to the cut part. Manufacturing a vehicle body for a track processing machine, comprising the steps of: constructing a track processing section on the support frame and attaching track processing sections between the cutting sections so that the processing sections can freely move between the support frame and the track. The present invention provides a method.

Further, the present invention provides a track consisting of a vehicle body that moves on a track and includes two rotating supports located at a constant interval, and a track processing unit disposed between the two rotating supports by a support frame. In a processing machine, the car body is formed from a standard freight car, the car is cut at least partially between its rotating supports to form a cut therebetween, a support frame is erected over the cut, and a track is constructed. The present invention provides a track processing machine characterized in that a processing section is attached to a support frame between cutting sections.

Therefore, according to the present invention, the above-mentioned technical and economical problems are solved by providing equipment that meets standards and mass-produced products, and therefore it can be manufactured at a relatively low cost.

It can also run on tracks at speeds sufficient to be incorporated into and hauled by regular trains.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the accompanying drawings, exemplary embodiments of the present invention, which are applied to track filling, leveling, and straightening, are shown by way of example and will be described in detail.

A machine 1 that can move freely on a track 4, as shown in FIG.
and two freight car parts 2A connected by a bridge-like support frame 3 with a displacement device 5.

This is a track processing machine for filling, leveling, and straightening, with a car body consisting of 2B.

Two freight car parts 2A of the car body of this track processing machine.

2B is constituted by two corresponding parts of a freight car 6, which (FIG. 2) is cut at a selected point C between two rotating supports.

Freight car 6 is selected from a mass-produced standard range of freight cars and is equipped with all the equipment that meets the standards governing the operation of the train.

The freight car is equipped with two rotational supports made up of two wheels 7 and 8, and the distance between the wheels is determined by the length of the support frame 3, which serves to connect the two freight car parts 2B and 2B. It is economically preferable to have a shorter difference than an approximately equal difference.

This bridge-shaped support frame 3 is firmly connected with its legs to the two wagon parts, for example by welding to the rails of the wagon, and is in a displaceable position with respect to the track handling section, i.e. the filling device 4, installed on the support frame. The device 5 is arranged in the space between the support frame 3 and the track and is fixed to the support frame.

The filling device 4 is attached in two pairs to a supporting section 10 that moves up and down, facing each other, and includes a vibrating pickaxe and a rotating shaft 9 that continuously tamp down the ballast in which the railroad ties are buried each time the track processing machine moves forward. It consists of.

The displacement device 5 comprises a so-called "universal" support 11 mounted on a support 12 which is movable both perpendicularly and transversely to the track.

The displacement device 5 operates every time the track processing machine moves forward, and if there is an error or defect in the level or straight section of the two rails of the track according to the conventional technology, it is detected by the control of an automatic device. Perform correct displacement work.

The filling device 4 and the displacement device 5, which are track processing units, are installed and operated in the usual manner, and their positions with respect to the two wheels 7 and 8 depend on the location of the cutting section C of the freight car that constitutes the body of the track processing machine. Determined by

A driver's cab 13, a hydraulic system 14 for driving the track processing section, and a retractable advancing device 15, which is shown enlarged in FIG. 3, are attached to both sides of the support frame 30 on this vehicle body.

This advancement device is separate from the rotation mechanism of the orbital processor and consists of the following:

= A lorry 16° supported on each rail by two wheels 17 (between which a Fuyo 18 driven by a hydraulic jack 19 is fixed) - This lorry 16 is attached diagonally to the vehicle body, and the roller is rotated in either direction. Hydraulic jack that translates in that direction.

- A device for hoisting the lorry 16 and fixing it to the vehicle body, consisting of a winch 21 and a support 22 with a fixing pin (for hoisting the lorry and engaging its corresponding support 23 with this pin).

During the work of filling sleepers, loosen Fuyo 18 and rolli 16.
The driving circuit of the jacks 19 and 20 of this advancing device is controlled from the cab 13 so that the track processing machine advances step by step by tightening the Fuyo 18 and continuously advancing the track processing machine. do.

This simple, robust, and inexpensive progressive device does not require any modification to the rotating mechanism of the freight cars that make up the car body, and the hydraulic circuit dedicated to the track handling section can be easily branched and driven. There are advantages.

Furthermore, in contrast to devices that are progressive by the action of the drive axle of a track processor, the action of this progressive device does not create unnecessary friction on the track surface.

With the same goal of saving and protecting the materials that make up freight cars,
FIG. 4 shows how it can be attached to the filling device and used to move the orbital processor a little, or for other types of processing that require continuous progressive movement during operation, such as vibrating rollers for tamping. A continuous progressive device is shown which may be equipped with a device for processing.

This continuous progression device consists of a device 24 in which a motor and a hydraulic speed reducer are incorporated, and is retracted upward by lifting the device. The bracket 26 is mounted on the reducer side by a double-acting lifting hydraulic jack 27.
It is connected to the.

The output arbor of the decelerator of this device is fitted with friction rollers 28 which contact perpendicularly the tires of wheels mounted on the axle 29 of the vehicle body of the track processor.

The so-called drive mechanism consisting of the jack 27 and motor speed reducer combination device 24 in this embodiment can also be driven by a generator that drives the track processing section installed in the track processing machine.

The motor/reducer combination device 2 is placed around the bracket 250.
4 rotates, the friction roller 28 draws an arcuate trajectory, but if this arc intersects the contact circle of the tire of the wheel mounted on the axle 29, the jack 27 moves the motor/recelerator combination. When the device is lowered, the drive pressure of the jack determines the friction of the roller.

Finally, it is possible to apply a propulsion system with continuous progression using a chain transmission, without having to remove and reinstall the wagon 60 rotation mechanism.

This embodiment is shown in partial cross-section in FIG.
Here, a circular groove is simply cut in a predetermined place on the tire of a wheel 31 attached to the axle of a freight car using a normal freight car wheel grinder, and the internal gear 33 is fitted into the groove and fixed with screws.

This internal gear is connected by a transmission chain to an output pinion (not shown) of a motor/reducer combination device fixed to the vehicle body of the track processing machine.

This embodiment is preferable to the embodiment shown in FIG. 4 when it is desired to continuously advance slowly when working and faster when driving.

The track processing machine according to the invention can be implemented in various ways depending on the type and importance of the processing performed by the track processing machine.

Light-duty filling equipment for mechanizing light work performed by workers on the tracks in station yards would not need to be equipped with intermittent or continuous automatic advancement devices.

This is different in the case of so-called "heavy-weight" filling equipment, which is used for more important tasks, such as filling switches and track intersections.

For such a filling device, the support frame 3 may be made elongated with reinforcement structures on the two wagon parts 2 and 2B of the car body.

On the other hand, when an ordinary freight car is chosen for a heavy-duty filling device, a freight car with two bogies may be used, in which case a combination device such as the motor shown in Figures 4 and 5 can of course be attached to the body of the bogie. Fix it.

Finally, when it is not necessary to remove all obstacles in the space between the support frame 3 and the track in order for the tools of the track processing section to pass, the cutting section C of the freight car is Partial cutting may be required, and it may be limited to structures included between the girders of the vehicle body.
