Description

Detailed Description of the Invention (Industrial Application) The present invention is a trackbed that is used for replacing trackbed ballast of trackbeds, etc., and has made it possible to significantly improve work efficiency through zero-mechanization. This invention relates to a ballast exchange device.

(Conventional technology) In order to mechanize trackbed-specific repair work, in recent years a method of replacing trackbed ballast using so-called general-purpose civil engineering equipment (hereinafter referred to as a trackbed exchanger) such as a backhoe or Yunbo has been introduced. developed and put into practical use.

For example, Utility Model Publication No. 58-30858 and Japanese Unexamined Patent Publication No. 57-33
In No. 601, a track bed replacement machine such as a backhoe is put into the track bed from a railroad crossing, etc., and carried to the track bed replacement point by running on the track bed by itself or running on rails, and using it to remove track bed ballast. A construction method for replacing the is disclosed.

However, with the former method of transporting the bed exchanger to the work point by running on the track bed, it is easy to damage the sleepers, etc., and to prevent this, it is necessary to lay rubber sheets, etc. The problem is that the sex is extremely bad.

In addition, in cases where tire-type wheels are used to reduce damage to railroad ties, etc., the ground contact force of the undercarriage is reduced, making it difficult to absorb the reaction force of the shovel during work, and causing the hardening of the hardened roadbed ballast. In some cases, there is a problem in that it is not possible to scoop out the trackbed ballast efficiently.

On the other hand, the track bed exchange type is run on the rails of 7 people (9
In such cases, the bed exchange machine must have a special structure equipped with 7eC wheels, which makes it impossible to use the general-purpose earthmoving machine t1, and it is time-consuming to tow the bed exchange machine to the bed exchange point. There is an At point that it takes a long time and cannot be used easily.

Also, at the action point, simply add the normal l; 1 to each # ring.
Since it is only necessary to apply mechanical braking or manually attach the bollard to the chichiwheel, the RGt easily slides on the rail due to the reaction force of the shovel during work, and in the case of solidified floor ballast, There is a problem that the track bed ballast cannot be scooped out with high efficiency.

On the other hand, in order to solve the above-mentioned problem, as shown in FIG. Drive truck a using the hydraulic drive source of the track bed exchanger A.
When the hydraulic motor is activated and the work point is reached, the track bed exchanger A is lowered onto the track bed in the same manner as during loading, and then a shovel is used to scoop out the track bed ballast. A device has been developed (Utility Model Application No. 60-12'8861, Utility Model Application No. 62-380)
No. 3, etc.).

However, the above-mentioned Utility Model Application No. 60-128861 and Utility Model Application No. 62
The device described in No. 3803 and the like has a problem in that the track bed exchanger A must be loaded and unloaded at the work site, and the actual work time is shortened accordingly.

In addition, in order to prevent damage to railroad ties, etc. due to track bed crossing gk[,:iA's caterpillars, it is necessary to lay rubber sheets, etc. at the work site, and it takes a lot of work to lay and remove them. .

Furthermore, in the conventional device, all the old track bed ballast etc. that has been scooped out is discharged to the side of the track bed and is disposed of appropriately by hand, so it requires a lot of work to dispose of the old track bed ballast that has been scooped out. do.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems in the conventional track bed changing device composed of a continuous track truck and a trackbed changer, namely: Since the basic method is to lower the trackbed onto the track bed and then operate the trackbed exchanger on the trackbed, it takes time to unload the trackbed exchanger at the trackbed exchange point, which shortens the actual work time. This is an attempt to solve the problems of L1, such as: ■ It takes time to prevent damage to railroad ties, etc., and ■ It takes time to dispose of removed trackbed ballast, etc., and so improvements are made to the bollard stop mechanism of transportation trolleys. In addition, a track-running dump truck that can freely replace tires and wheels and runs on rails by carrot drive is incorporated into the exchange device, and a trackbed exchange machine is installed on the transport trolley. To provide a trackbed ballast exchange device capable of exchanging trackbed ballast with extremely high efficiency by scooping up the trackbed ballast, etc., while the trackbed ballast remains in place, and discharging the scooped trackbed ballast etc. by a track running dump truck. It is.

(Means for Solving the Problems) The present invention provides a track dump truck in which the tires and iron wheels are replaceable and which travels on rails driven by an engine to transport trackbed ballast, etc.; A trackbed exchanger such as a backhoe equipped with a device; It consists of a driven truck and a driving truck, and runs on the rail by the drive source of the loaded truckbed exchanger, and a reaction force receiver operated by the drive source of the truckbed exchanger drives the device. A trackbed exchanger comprising the driving truck and a transportation truck each having a braking device on the driven truck, and loaded on the transportation truck,
The basic structure of the invention is to scoop out trackbed ballast.

(Function) At railroad crossings, etc. near work sites, the bed exchanger uses its own blade to load electricity onto the transport trolley, and the drive source of the track bed exchanger drives the transport trolley to travel on the rails and reach the work position. do.

After that, with the track bed exchanger tightened on the transport trolley, the shovel is placed in front of the trolley, and the track bed ballast in the space formed by moving the sleepers in advance is moved toward the front by moving the shovel. scoop it up.

On the other hand, at the railroad crossing, etc., the tires of the track-running dump truck are replaced with iron wheels, and the dump truck is placed on the rails and transported to the work site by the engine 171 (generally available).

The scooped ballast is discharged onto a track running dump truck which is placed behind the transport trolley, and the dump truck is run on rails to be transported to intermediate locations near railroad crossings, etc. , you can learn about land and transportation dumps, etc.

By scooping up the track bed ballast, the transport truck attempts to move forward (towards the excavator) due to the reaction force.

However, since there is a bollard fixed to the rail at the front of the iR truck wheels, forward movement of the iR truck due to reaction force is completely blocked, making it extremely smooth. It is possible to scoop out roadbed ballast.

In addition, when the reaction force receiver provided on the drive bogie is activated, the car stop body is pushed out in the axle direction and downward direction by the hydraulic cylinder, and is pressed against the inner side surface and tread surface (top surface) of the rail. .

As a result, the bollard is very firmly fixed to the rail at a position in front of the bogie wheel due to friction with the rail, and the movement is smooth.
'Advancement due to the reaction force of the immersion truck is reliably prevented.

On the other hand, almost no rearward reaction force is applied to the truck because the shovel is pulled toward the front to scoop up the pallast. However, when the excavator is used to push the sleepers forward in sequence, a slight reaction force is generated in the rear, but this reaction force is caused by the mechanical braking that acts on the wheels of the trolley.
Uke can be stopped enough.
