Description

[Detailed Description of the Invention] [Industrial field of application] The present invention mainly relates to a transportation vehicle for laying gravel or the like laid on a roadbed.

[Conventional technology]

Conventionally, when a roadbed on which a track is laid is newly installed, or when gravel on an existing roadbed is replaced or replenished, a transportation vehicle traveling on the track is used.

[Problems to be solved by the device]

Since the above-mentioned conventional transport vehicle has a double-sided dump structure in which the bets cells loaded with gravel dump to the side, when laying on the roadbed, after dumping once to the side of the roadbed, the work vehicle carries it to the center side of the roadbed. In addition to the need, dumping the bet cells causes most of the gravel in the bet cells to fall, and the amount of fall cannot be adjusted, so that they cannot be evenly distributed on the roadbed.

For this reason, it takes a lot of time and labor to carry it to a predetermined position after dumping, which causes a problem such as poor work efficiency.

The present invention has been made for the purpose of improving the above problems, and an object of the present invention is to provide a transportation vehicle capable of efficiently carrying and spraying gravel and the like.

[Means and Actions for Solving the Problems]

In order to achieve the above object, the present invention detachably installs a bet cell that can be dumped rearward by a dump cylinder on a bogie that can travel on a track, and gravel inside the vessel on both sides and rear surface of the rear part of the bet cell. By providing doors that can be opened and closed to distribute and drop, and a guide that distributes gravel in the vessel toward the door near the inside of these doors, gravel can be evenly distributed on the roadbed and the slope of the bezel Is provided to a transportation vehicle in which the amount of gravel falling can be adjusted arbitrarily.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 1 denotes a trolley which can be freely driven on a track 23 by a wheel 2 provided at a lower portion, and a front and rear portion of a lower portion in a direction orthogonal to the wheel 2. Auxiliary wheels 3 used for moving to the main line are provided, and these auxiliary wheels 3 can be evacuated from the main line by mounting them on a retreat track laid at a right angle to the main line track. .

In addition, the wheel 2 is provided with a parking brake 4,
Wheels 2 can be braked when parked on an orbit, and a pallet 1a is provided on the dolly 1, and a bet cell 5 is detachably attached to the pallet 1a.

The above-mentioned Bethel 5 has a rectangular box shape with an open upper surface,
A bracket 6 is projectingly provided on the bottom surface on the rear side, and the bracket 6 and the carriage 1 can be connected by a pin 7. The bottom surface on the front side is tapered at the tip side as shown in FIG. The locating pins 8 are projected at two places, and when the bezel 5 is attached to the dolly 1, these locating pins 8 are attached to the pin receiving member 9 on the dolly 1 side.
The bezel 5 can be positioned with respect to the carriage 1 by inserting the pin 7 into the pin hole 6a of the bracket 6 easily.

Reference numeral 10 is a retaining pin for the pin 7.

On the other hand, a dump cylinder 12 is obliquely provided between the trolley 1 and the upper portion of the bezel cell 5 on which the positioning pin 8 is provided, and the bezel 5 is moved rearward around the pin 7 by the dump cylinder 12. You can dump to.

On the rear side of the bezel 5 are provided doors 13 and 14 which can be opened and closed on both side surfaces and end surfaces.

The upper portions of the doors 13 and 14 are hinged to the upper portion of the bet cell 5 by the hinges 15, and the lower end sides of the doors 13 and 14 are opened outward around the hinges 15. The lower portions of the doors 13 and 14 are locked by the lock levers 16a. A locking mechanism 16 that can be freely locked is provided.

Inside the bet cell 5 near the doors 13 and 14, a triangular pyramid-shaped guide 17 for projecting the falling direction of the gravel contained in the bet cell 5 in three directions is provided so as to project from the bottom surface.

In the figure, reference numeral 18 is a receiving block projecting from the bottom surface of the bezel 5 and adapted to bear the load of the bezel 5 by contacting the upper surface of the carrier 1a of the carriage 1.

Further, reference numeral 19 in the figure denotes a connector for towing by a towing vehicle 21.

Explaining the operation next, when the above-mentioned transportation vehicle is towed by a towing vehicle 21 such as a track work vehicle that is self-propelled on a track 23 to be moved to a work site and sprays gravel onto a roadbed 22, first spray it. The locking mechanism 16 of the doors 13 and 14 in the direction to be removed is removed.

In this state, when hydraulic pressure is supplied from the towing vehicle 21 side to the dump cylinder 12 via a pipe (not shown), the dump cylinder 12
Expands and the Bethel 5 dumps around the pin 7 as shown in FIG.

As a result, the gravel in the bet cell 5 is dropped onto the roadbed 22 by opening the unlocked doors 13 and 14 by its own weight, and is evenly scattered on the roadbed 22.

Also, if a certain amount of gravel is dropped onto the roadbed 22,
By shortening the dump cylinder 12 and reducing the inclination of the bezel 5, the amount of gravel falling can be adjusted arbitrarily, so that a predetermined amount of gravel can be accurately sprayed onto the roadbed 22.

By repeating the above operation while pulling the truck 1 by the towing vehicle 21, a predetermined amount of gravel can be evenly distributed on the road bed 22.

It should be noted that by removing the bet cell 5 from the top of the carriage 1, it can be used for transportation such as a track using the loading platform 1a above the carriage 1.

[Effect of device]

As described in detail above, this invention can selectively disperse the gravel contained in the bet cell to the center and both sides, so that the gravel dropped to the side of the bed is transported to the center of the bed as in the past. The work of doing so becomes unnecessary, and the amount of gravel falling can be adjusted arbitrarily by changing the inclination of the bet cell, so that it can be evenly distributed on the roadbed.

As a result, the time and labor required for the work can be significantly reduced as compared with the case where the vehicle is dumped to one place like a conventional transport vehicle and is transported from there by a work vehicle or a worker. You will be able to make good improvements. In addition, by finely adjusting the inclination angle of the vessel with the dump cylinder, the gravel and the like in the vessel will not be suddenly biased or discharged at one time, so the vehicle will tip over due to bias of the load or discharge inertia. There is no fear and the work can be completed completely.
