Abstract

PURPOSE:To enable efficient renewal of tracks with the different gages by making the gage of wheel holders on both sides having a rail clamp variable and providing outriggers which are capable of being elevated up and lowered down on their both sides so as to put a rail between them capable of being longitudinally fed. CONSTITUTION:A track skeleton longitudinally feeding truck 20 is composed under a car body 21 in the shape of a small trolley with wheels 2, wheel holders 24 having a rail clamp 23, and so on. And the wheel holders 24 are connected to each other through gage change cylinders 25 which are adjustable to the broad or narrow gage. Also, each gage change cylinder 25 is connected to a hydraulic pump 50 through a hydraulic control valve 51 and so constituted that the gage width is controllable so that the wheel holders 24 slide along a guide 26 by a roller 27 brought into contact with a jaw part of the rail clamp 23 when the gage change cylinder 25 is disposed. By this, not only existing tracks but also tracks with the different gage can be efficiently renewed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a track exchange machine for updating and replacing existing tracks of railway vehicles.In particular, when updating to a track with a different gauge, the rails can be used as they are. The present invention relates to a vertical rail transport truck that grasps and transports rails for replacement while disassembling and reassembling each block.

(Conventional technology) Conventionally, when replacing rails, sleepers, etc. on existing tracks, new materials were brought to the site, the existing track was dismantled and removed block by block of regular length rails, a new track bed was leveled, and then the new track bed was replaced. New railway sleepers are lined up at predetermined positions on the floor, then rails are placed on these sleepers to connect them, the new rail is assembled, and finally ballast is added and refilled to compact and renew the existing rail on-site. Line up sleepers on top, put rails on top of them, fasten them and assemble them into a new rail stile, then temporarily install road rails on both sides of which the rail stile transportation machine can run, and transport the rails using several crane vehicles. There is a method in which a machine is set up, the new rail stile is hoisted up, and the old rail stile is removed and the new rail stile is moved onto the trackbed where the ground has been leveled for renewal.

On the other hand, a method based mainly on mechanical power is to organize a group of large construction machinery vehicles, load a large amount of new softwood, drive to the site, remove the fastening fittings of the existing track, and drive slowly while automatically At the same time, the old rails and sleepers are dismantled and recovered, the trackbed is leveled, new sleepers and rails are continuously supplied and arranged in the designated positions, and after they are fastened together and the new rail stile is assembled, the ballast is removed. Complete the work while replenishing and solidifying it. All of this work is carried out using large-scale mechanical power combined with a crane truck, allowing highly efficient track renewal with a small number of people.

Also, unlike this method, the newly assembled tracks are loaded onto transport vehicles at the base, and a train connected to a large crane vehicle is formed and transported to the site, where the existing tracks are hoisted block by block from the end and removed and recovered. There is also a method of updating the rails by sequentially replacing them with new rails. This method of making full use of large groups of construction and machinery vehicles is effectively used in continental areas such as Europe, where there are relatively flat, straight sections and there are few private houses along the lines.

[Problem to be solved by the invention]

As with the above method, where the sleepers are lined up on the track bed, it is not possible to ensure sufficient horizontality of the sleepers, and it takes time to connect the sleepers to the rail.Also, with the method using a track transporter, the connection can be done efficiently, but the rail There was a problem in that it required a lot of effort to move vertically using a stile transporter and move and install temporary road rails.

In addition, large-scale renewal methods in which all track materials are continuously renewed at once using large construction machinery vehicles tend to cause environmental problems such as noise in countries like Japan where there are many residences along railway lines. In addition, in areas where the topography of the track route and frequent train operation conditions are complex, it is difficult to introduce large construction machinery, and even if mechanical power is used, rails, sleepers, ballast, etc. The problem was that the investment effect could not be fully utilized because the upgrades were carried out in stages, with each part being divided into separate pieces of work. In particular, methods based mainly on human labor have the advantage of being able to respond freely even when the orbit route environment changes, but they require a large number of workers, and methods in continental countries such as Europe require most of the renewal work. Since this is done mechanically, fewer workers are required, but economically it requires a large installation burden, a commensurate amount of continuous work (renewal distance), and sharp curves and
In addition to not being able to demonstrate sufficient performance on tracks with steep gradients and many bridges and roads, special vehicle structures are required when replacing the existing track with a different gauge using the same rails. There was also the problem of having to secure highly skilled personnel to operate these construction machines.

The present invention has been made to eliminate the above-mentioned drawbacks, and it does not require on-site workers to carry out heavy or dangerous work such as transporting pile materials, and it also avoids heavy economic burden. Providing a track vertical feed truck that can efficiently update or change the track for each block by dismantling, removing, and transporting existing tracks and assembling and laying new tracks with different gauges even on site. It is something to do.

(Means for Solving the Problems) A rail vertically feeding bogie according to the present invention has a chassis on which wheel holders on both sides having wheels and rail clamps are attached with variable gauge width, and a chassis on both sides of the chassis that can be freely raised and lowered. The rail is provided with an attached outrigger means, and the rail is clamped so as to be vertically conveyable by a roller at the tip of the rail clamp that comes into contact with the rail jaw.

(Function) According to the tracked vertically feeding bogie according to the present invention, there is provided a chassis to which wheel holders on both sides having wheels and rail clamps are attached with variable gauge width, and an outrigger means attached to both sides of the chassis so as to be able to rise and fall freely. By having the rail clamped so that it can be moved vertically by the roller at the tip of the rail clamp that contacts the rail jaw, the existing track can be efficiently updated not only to a track with the same gauge but also to a track with a different gauge.

In the figure, (lla) is a sleeper supply vehicle that is towed by a motor car (lea) and serves as a sleeper supply means for supplying and transporting broad gauge sleepers (6) connected to the sleeper loading/unloading ratio (12a) at the front. The sleeper supply vehicle (tta) will be introduced from the wide gauge (3) side, which has already been updated, and will be installed on the broad gauge sleeper (6).
is supplied to the broad gauge sleeper loading/unloading rate (12a) as a sleeper unloading means, and this sleeper loading/unloading rate (12a) is applied to the specified broad gauge (3) at the site.
The broad gauge sleepers (6) are removed from 12a) and placed there.

On the other hand, from the narrow gauge (2) side, which has already been cleared and leveled by the palust cleaner, the narrow gauge vertical feeder (20), which serves as a vertical feed bogie, is installed at the beginning to move to the existing narrow gauge stile replacement part.

The rail clamp (23) consists of hanging metal fittings (23a) and (23b) as a pair of gripping members, and these gripping members (23a) and (23b) are connected to a widened hydraulic cylinder (55) via a link (54). are connected to both ends of the wheel support body (24), respectively, and are attached to the wheel support body (24) so as to be movable up and down by hydraulic control (see Fig. 2).

FIG. 8 shows another embodiment of this rail clamp (23), in which the side of the rail clamp frame (70) has
A cylinder bearing (72) is fixedly installed, and this cylinder bearing (
A double-acting hydraulic cylinder (71) is swingably connected to the hydraulic cylinder (72) via a bearing pin (72a). Also, the rod (
One end of 73) slides reciprocally within the cylinder (71), and the other end is coupled via a joint (74) to the arm portion (230a) of the hanging fitting (23a). The roller support parts (231a) and (231a) provided at the inner ends of the pair of hanging fittings (23a) and (23b)

(76b), respectively, so as to be integrally rotatable. Note that the stopper (77) comes into contact with the arm (230a) to regulate the position at which the roller (27) clamps the rail jaw.

Next, the operation of this rail clamp (23) will be explained. When hydraulic pressure is introduced from the hydraulic equipment into the -chamber of the cylinder (71), the rod (73) moves to the left in the figure and is displaced upward following the bottle (78) of the arm portion (230a). The tip of the rod (73) is displaced in an arc until the portion (230a) comes into contact with the abutting member of the stopper (77). Therefore, according to the movement of the arm part (230a), the hanging metal gears (76a) and (76b) rotate forward and backward, respectively, and the hanging metal gears (23a) and (2
3b) grips the rail jaws.

In addition, when this rail clamp (23) rises from the state where it grips the rail to the predetermined standby position as described above (see Figure 8 (c)), the pressure oil from the hydraulic equipment is released into the switching valve. When the rod (73) moves to the right in the reverse order of the above, the hanging metal gears (76a) and (76b) move toward each other according to the movement of the arm (230a). Rotates forward and backward,
The hanging fittings (23a) and ('23b) are held in the upper standby position.

Further, on both sides of the chassis (21), there are lift cylinders (31) which are connected to a hydraulic pump (50) via lift cylinder hydraulic control valves (56) and are controlled to be raised and lowered by hydraulic control. An outrigger (30) that is movable in the vertical direction is attached to the lift cylinder (31) and a lift post (32) that is integrally attached to the chassis (21).
is supported so that it can be raised and lowered freely.

This vertically moving bogie (20) has running wheels (22) installed under the chassis (21) via wheel supports (24) that can be adjusted to suit any gauge, such as wide or narrow gauge. ,
In addition to being able to run on orbit and be towed back to the renewal site, it can also be equipped with an engine or other power source and propelled by hydraulic drive. In addition, in order to travel on a suitable broad gauge track and transfer to a narrow track, connect and extend a short broad gauge light temporary rail of around 1 m at the contact point and temporarily install it overlappingly on both sides of the narrow track.
Move to the temporary broad track, and first push down the outriggers (30), which are provided in pairs at both ends of the chassis (21), with the lifting cylinders (31).
Then, the wheels (22) are moved to the inner narrow gauge position using the same hydraulic operation, and the hydraulic control valve (56) of the lifting cylinder (31) is opened again to raise the chassis (21).
By lowering the vehicle, placing the wheels on the existing narrow track, and then raising the outrigger (30) to its original position, the vehicle can run on the narrow track.

When this track vertical feed truck (20) is installed at a predetermined replacement section of the existing track, from the narrow gauge sleeper loading/unloading truck (12b),
A two-wheel carrier (40) is placed horizontally on the existing track (2) on the side of the vertically-transporting trolley (20), and serves as a carrying means for carrying and transporting the rail (2) and the rail (2a). After unloading the railway sleepers, the railway sleeper loading vehicles consisting of the narrow gauge sleeper loading and unloading vehicle (12b), the sleeper recovery transport vehicle (llb) and the motor car (10b) are moved to the existing track side by the length of the existing track that is to be replaced. Retreat to complete the work start arrangement (first step)
.

This two-wheel carrier (40) is used in conjunction with the vertical rail transport trolley (20) when transporting, removing, and laying the rail. Lifted rail (2
a), the same number of two-wheeled carriers (40) as the vertical carriages (20) are lined up and waiting at the end of the existing track on the sending side, and the vertical carriages (20) When the end of the track (2a) that was lifted and transferred is bent and lowered, each car receives the rail between each sleeper on the base frame of the two-wheel carrier (40) at a predetermined interval. , the removal will be completed while transferring the existing tracks one by one.

When laying a new rail stile, in the reverse order of removal, the new rail stile assembled on the newly constructed track is distributed between the sleepers at predetermined spacing positions using the same number of two-wheel carriers (40). Vertical rail transport bogie (20) left as it is and waiting after the old rail is removed to the position where the rail will be laid on the sending side.
The rollers (23) of the rail clamp (23) of the vertical feed truck (20) begin to move towards the rail jaws of the new rail stile.
27) If the two-wheel carrier (40) is successively inserted or sandwiched between the two and hoisted to a predetermined height and transferred further, the two-wheel carrier (40) will move away from the new rail stile one after another from the leading car and reach the end of the new track. The rest are assembled, and the new rail stile is placed on the track vertical feed bogie (
20), and after reaching the fixed position, it is gradually lowered by the outriggers (30) to complete the installation.

Moreover, the wheels (42) of this two-wheeled carrier (40) can be raised and lowered to a predetermined vertical position around the base frame by hydraulic operation, so if the wheels (42) are brought to the lower position, the track can be lifted. It can be used as a stile transfer trolley, and when raised to the upper position, it can be used as a rail transfer roller.

Next, the track replacement work will be explained based on FIGS. 3(a) to (e).

From the first process (see Figures 3(a) and 4(a)), where the work start placement has been completed as described above, the work was placed on the track (2a) of the existing track replacement section. Track vertical feed cart (
Lower the rail clamp (23) of 20), clamp the jaws of the existing narrow gauge rail (2), and attach the outrigger (30).
, and lift the chassis (21) and wheels (22) from the track bed (4) with the rails (2) being held by the rail clamps (23) integrated with the wheels (22) (Fig. 3(b)
), see Figure 4(b)). Next, this gauge (2a) is attached to the winch (14) installed on the narrow gauge sleeper loading/unloading vehicle (12b).
b) via wire lobes (15b), and this gauge (2a) is vertically fed to the existing narrow gauge side, first with wheels (
42) to the lower position and tie it on the transport trolley.The narrow gauge stile (2a), which has been lifted and transferred by the vertical transport trolley (20), is placed on the narrow gauge two-wheel carrier (4o) that is waiting on the existing narrow track.
), and after transporting and removing it to the designated location, dismantling begins immediately (second process, Figure 3 (C), Figure 4 (C)
, see (d)).

In the next process, after dropping the dismantled and separated sleepers (5) onto the existing narrow gauge, the wheels (42) of the two-wheeled narrow gauge carrier (40) are
) in the upper position, the separated rail (2b)
The rail (2b) rests on the wheels (42), and the winch (1
4a) via a wire rope (15a), and this rail (2b) is sent back to the newly installed broad gauge side (see Figures 3(d) and 4(e)).

Then, the rail (2b) is successively inserted and fed into the rollers (27) of the rail clamp (23) of the rail vertical feeder (20) which is floated by the outrigger (30), so that the entire length of the rail (2b) is It is maintained in a suspended state within the rail vertical feed cart (20). Next, if the wheels (22) of the vertical track carriage (20) are laterally displaced to match the broad gauge gauge, the rail (2b) will also be in the broad gauge position at the same time (Fig. 4 (f)), and this will happen again. Rail (2b
) will be transferred to the newly constructed broad gauge railway.

On the newly installed wide track side where a new broad gauge frame is assembled, a two-wheel carrier for broad gauge (40a), which has the same configuration as the two-wheel carrier for narrow gauge (40) and whose gauge is set for broad gauge, is used as a sleeper for broad gauge. (
6) at a predetermined interval, and initially the wheels (42a) thereof are raised to an upper position and are on standby. A new broad gauge system in which the rails (2b), which have been transferred as a broad gauge gauge using a longitudinal feed truck (20), are arranged on the wheels (42a) along with the two-wheel carrier (4Qa) as guide rollers. It is moved above the sleeper (6) and carried into its predetermined position (Fig. 4 (g)).

Furthermore, the rail (2b) carried in riding on the wheels (42a) of the two-wheeled broad gauge carrier (40a) is moved to the new broad gauge sleeper (6) when the wheel (42a) is lowered and stored inside.
) is placed in place and immediately replaced with a new broad gauge stile (3a).
Assemble (fourth step).

In the process of this fourth step, the rail (2a) is dismantled and separated, the rail (2b) is transported back to the rail vertical carriage (20), and the sleeper (5) left on the existing narrow gauge is loaded according to the narrow gauge sleeper loading/unloading rate (12b), and the sleeper collection and transport vehicle (l

Sleeper supply and collection vehicles (lla) and (llb) are:
Construction vehicles such as iron trolleys are commonly used, with broad gauge for delivery and supply, and narrow gauge for delivery and collection.
Other than having different gauges, they have the same functional structure. A pair of roller conveyors are arranged parallel to each other on the undercarriage floor, on which the sleepers (5) and (6) are loaded side by side, and during unloading and loading, the rolling conveyors are fed in a direction perpendicular to the rails. It is now possible to do so. When traveling, sleepers (5), (
6) Fall prevention stoppers are provided on the front and rear of the vehicle chassis, and when used on site, the stoppers are removed and another roller conveyor is placed between the transport vehicle (llb) and (llb). Each transport vehicle (llb) with connected sleepers,
