Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is used in conjunction with the work of fastening continuous long rails, so-called long rails, to sleepers in railway track replacement work. This invention relates to a device that continuously attaches fuel for heating the rail to the side of the rail to set the length by thermal expansion by heating the rail.

<Conventional technology> When replacing rails on railway tracks due to aging or damage, the rails are constantly expanding and contracting in response to changes in temperature throughout the seasons, so it is always necessary to expand the rails before replacing them. must be carried out. However, recently the rails have become longer, and each length is 700 to 1.
It is extremely long at 000m. Therefore, in order to construct this long rail, No. 6 is used in which manufactured rails of fixed length are sequentially welded and connected. When replacing and installing such long rails, when fixing the rails to sleepers on the trackbed, it goes without saying that the entire length of the rails must be heated and fixed. The longer the wire is, the more work is required to heat it over its entire length.

To heat the rails, one worker determines the area that can be heated and uses a welding burner or the like to heat the rails. Therefore, when the rails are long, dozens of workers must heat the rails at the same time, making the work extremely difficult. Moreover, since this work must be done during times when trains are not in operation, there are many problems, such as the fact that the work must be done efficiently and in accordance with the instructions of the supervisor.

(Problem to be solved) - As described above, the conventional rail heating work requires a large amount of labor by many workers, and is heated using welding burners at multiple points, so it cannot be heated evenly. Due to individual differences among workers, the heating process inevitably varies and requires excessive heating fuel, which not only reduces work efficiency but also unavoidably wastes auxiliary materials.

In order to solve these problems, the present invention attempts to continuously apply paste-like fuel along both sides of the rail web from the top of a running vehicle, and ignite this fuel to connect the rail. The object of the present invention is to provide a traveling type fuel impregnation device that attaches paste-formed fuel to a rail so that uniform heating can be easily performed over the entire length of the rail.

(Means for Solving the Problems) The present invention has a heating fuel storage tank, a fuel discharge pump, and a fuel discharge pump connected to a running vehicle that can run on a track to deliver a highly viscous fuel to a target location. The vehicle is equipped with a support mechanism for the discharge nozzle for adhering the heating fuel, and the heating fuel discharge nozzle is located at the end of the support arm attached to the truck so that the fuel is discharged toward the web side of the rail. The pump is supported, and the pump discharge port is connected to the discharge nozzle by piping.

In addition, the support arm for the discharge nozzle in the present invention has a base movably attached to the end of the truck, and a small wheel that moves on the rail at the tip, so that the tip of the discharge nozzle remains constant with respect to the rail. By making it possible to face the position of the rail, fuel can be attached to a specific position of the rail in a constant state.

Further, the discharge nozzles in the device according to the present invention are configured as a pair, and are arranged inward from the bifurcated portion that straddles the head of the rail so that the tip approaches the rail. It is attached so that it can rotate based on the nozzle pipe or connection axis from the part, and it can be used to set the discharge conditions for the fuel rail and to move it without touching the rail head when lifting upwards outside of fuel impregnation work. can be formed into

Furthermore, if the traveling trolley is equipped with an engine so that it can run on its own, it is possible to maintain a fixed amount of fuel and carry out a fixed amount of impregnating operation. Incidentally, if the operator is allowed to board the traveling cart, the process can be further streamlined.

Furthermore, as for the pump mounted on the traveling vehicle, an air-driven plunger pump built into a heating fuel tank, a tube-type rotary pump, a gear pump, etc. can be used.

As the heating fuel, a paste made by adding 93% methanol and the remainder such as a gelling agent is used.

(Function) In the device of the present invention, a traveling bogie is placed on a track temporarily laid on the track bed for replacement, and the heating fuel discharge nozzle is arranged so that the discharge port faces the web side of the target track. While running the traveling truck at low speed, the mounted pump is driven to send heating fuel toward the discharge nozzle. The amount of heating fuel delivered by the pump can be set by adjusting, for example, a valve or the like, and the heating fuel can be delivered from the delivery nozzle so that the heating fuel adhering to the rails is not interrupted during running.

By setting the traveling speed of the traveling truck and the amount of heating fuel discharged from each discharge nozzle in advance, the heating fuel can be continuously attached to the web side of the rail in the form of a string. For example, a single operator of the traveling truck can easily prepare for heating by attaching heating fuel to the rail.

During this heating fuel attachment operation, the support arm, which is the main support mechanism for the discharge nozzle, is made vertically movable and moved up and down along the rail, thereby keeping the discharge end of the discharge nozzle constant with respect to the rail. This will result in fuel sticking.

In addition, if the discharge nozzle is configured to rotate about the axis at its mounting location, the discharge end of the discharge nozzle can be brought close to a desired position on the web of the rail and the fuel can be deposited thereon. Moreover, when the discharge nozzle and its support mechanism are removed from the vicinity of the rail without performing a discharge operation, the discharge nozzle can be rotated outward and pulled upward without contacting the rail.

(Effects of the Invention) According to the device of the present invention, the operator stores the required fuel in the heating fuel storage tank on the traveling truck, operates the pump,
By running the traveling trolley, even if the rail to be heat treated is long, it can be impregnated with heating fuel with a minimum number of workers.Thereafter, by performing the simultaneous ignition operation, the entire length of the target rail can be coated with heating fuel at once. It is now possible to heat evenly. The number of personnel required for this heating work is significantly reduced, and the heating work can be carried out safely and reliably in a short period of time, making it a useful invention that helps streamline the work of laying long rails.

(Example) An example of the present invention will be described below based on the drawings.

What is shown in FIGS. 1 to 5 is a fuel impregnation device 1 for connection heating in which necessary equipment is mounted on a walking-type traveling trolley 10 that is manually pushed by an operator.

This traveling bogie 10 can freely run by pushing a push frame 11 on a track that has been temporarily laid on a track bed with the rail 3 that is to be installed by replacement set to a predetermined gauge.

On the traveling truck 10, there is a storage tank 15 for heating fuel,
A pump 1 that sends out heating fuel in the storage tank 15
7 (In this specific example, air-driven 1 lancier pump 1
7 or M15" above the storage tank 15" and the near compressor 1 for driving the pump 17.
8 and an internal combustion engine 19 are installed.

A pair of brackets 20 are provided at the rear end of the traveling trolley 10 (on the left side in the figure, opposite to the direction of movement during work), and support arms 22 are attached to both ends of a shaft 21 supported by the brackets 20. It is rotatably mounted at the base. At the tip of this support arm 22, a wheel 24 is attached to the lower side via a mounting seat 23 with a support bracket 25 thereof, and a support plate 26 for a discharge nozzle 30, which will be described later, is attached upward.

The discharge nozzle 30 includes a support plate 26 attached to the tip of the support arm 22 and a support piece 2 attached to the upper side near the base.
7, a bifurcated discharge nozzle base pipe 31 detachably attached and supported, and connected to each branched tip of the discharge nozzle base pipe 31 via a pipe joint 33, with the pipe axis as a reference. The front end of the nozzle pipe 32 is curved so that it can be rotated by the handle.In the working state, the tip of the nozzle pipe 32 is connected to a corner part where the web 3' of the rail 3 to be treated and the support flange 3'' are connected. (not limited to), heating fuel can be discharged and impregnated.

The heating fuel supplied to the discharge nozzle 30 having such a configuration is supplied to the pump 17 assembled in the storage tank 15.
is sent from the discharge port 17' to the discharge nozzle base pipe 31 via the T-shaped branch pipe 35 and the hose 36 connected thereto,
It is branched at the discharge nozzle base pipe 31 and discharged from each nozzle pipe 32. In addition, the T-shaped branch pipe 35
Both discharge nozzles 30.30
This allows the heating fuel to be distributed and supplied equally to the required amount. The flow rate adjustment for each discharge nozzle 30 by the individual valve 37 described above is performed once.
The amount collected in one place = 10 = It may be adjusted by valve control.

The pump 17 employed in this embodiment is a plunger-type high-viscosity fluid pump operated by compressed air from a small near compressor 18 driven by an internal combustion engine 19 mounted on a traveling truck 10. Also,
The heating fuel used is a paste made of 93% methanol and the remainder such as a gelling agent. Therefore, in order to send out the handling heating fuel, which has a high viscosity, from the discharge nozzle 30 to the target location without interruption, it is necessary to connect the heating fuel so that it is actively sent from the storage tank 15 to the suction side of the pump 17. It is necessary to keep To this end, in this embodiment, the pump body is inserted into the storage tank 15 from the center of the lid 15' of the heating fuel storage tank 5, and the movable lid 16 is inserted into the storage tank 15. (heating fuel) so that as the content decreases due to pumping of the pump 17, the heating fuel is pushed into the suction side of the pump 17 by the pressure difference between the upper and lower compartments via the movable lid 16. It is configured.

In addition to the above examples, the heating fuel delivery pump may be a tube-type rotary pump or a rotary pump used for transferring highly viscous materials, such as a gear pump. For these pumps, the intake port of the storage tank is connected to the pump inlet so that the pump suction side is pressurized by using the gravity head from the heating fuel storage tank. Leave it there. Regarding the drive of the pump, as in the above example, the air motor is driven by compressed air from an engine-driven compressor, the electric motor is driven by an engine-driven generator, or the pump is driven directly by the engine. Either of these can be adopted. When a rotary pump is used, a large storage tank can be mounted on a traveling truck, making it useful for long-distance track heating work. Of course, even in the case of the plunger type pump 17, if two storage tanks 15 each incorporating the pump 17 are installed in each discharge nozzle 30, attachment work over a long distance can be performed.

The attaching device 1 of the present invention configured as described above is configured such that the long rail 3 to be replaced is placed on the temporarily laid track, and the operator pushes the push frame 11 to move the traveling cart 10. do. In order to attach the heating fuel to the target position of the rail 3, that is, to the corner part 3a formed by the web 3° and the support flange part 3'', lower the support arm 22 to the rear side, and attach the heating fuel to the lower part of the tip. The attached wheels 24 are placed on the head 3b of the rail 3 so that the discharge nozzle 30 attached to the support arm 22 follows the movement of the traveling carriage 10. In addition, prior to starting work, the nozzle pipes 32, 32 of the discharge nozzle 30 are as shown by solid lines in FIG.
The rotation is adjusted and set so that the discharge port 34 faces close to the corner portion 3a of the rail 3. At this setting, joint nut 3
Tighten 3' to fix it so that it does not move.

When preparations are complete, the internal combustion engine 19 on the traveling trolley 10 is started to operate the compressor 18, and the compressed air adjusted to the required pressure by the pressure reducing valve 38 is fed to the driving part of the pump 17 (the plunger is moved up and down by an air motor). feed, the pump 1
7, the fuel for heating 3 in the storage tank 15 is sent out. The pasty heating fuel sent out by the pump is passed through the valves 3 at both ends of the T-shaped branch pipe 35.
7.37, the supply amount to each discharge nozzle 30.30 is adjusted so that both are discharged in approximately equal amounts.

In this way, when the operator moves the traveling trolley 10, the paste-like heating fuel 5 is formed into a string from the branched nozzle pipe 32 end discharge port 34 of each discharge nozzle 30, and the rail 3 is It is attached to both corners 3a. therefore,
By moving the traveling carriage 10 in accordance with the amount discharged by the nozzle pipe 32 of the discharge nozzle 30, the amount of heating fuel 5 attached is determined.

The attachment position of the heating fuel 5 is always determined at a constant position because the support arm 22 of the discharge nozzle 30 traces the upper surface of the head 3b of the rail 3 by the wheel 24 attached to the tip as described above.

Note that the discharge nozzle 30 comes into contact with the head 3b of the rail 3 by rotating the tip of the nozzle pipe 32 outward until the work of attaching the heating fuel 5 is finished and the next work is started. By fixing the support arm 22 together with the support arm 22 to the shaft 21 with the fixing screw 28 attached to the base of the support arm 22 (not shown with chain lines in FIG. It can also make it easier to travel after work.

In the above embodiments, the operator moves by pushing the traveling trolley 10, but it is also possible to make the traveling trolley an engine-driven self-propelled type so that the worker can ride and drive it. This will make the traveling speed constant, further improving operability, and will greatly contribute to streamlining the work of impregnating heating fuel over long distances.
