Description

[Detailed Description of the Invention] The present invention is applied to traveling rails with a small radius of curvature? This invention relates to an excavation device that automatically orients the axle of a traveling bogie in the normal direction of the traveling rail.

Do carts used for cargo handling in steel plants run on rails with a small radius of curvature? In the case of commonly used fixed axle type bogies, the non-perpendicularity of the axle to the running rail becomes large, causing phenomena such as squeaks and slipping between the wheels and the rail, which can shorten the life of the rails and wheels. Problems such as shortening, increased running resistance, and noise generation have arisen.

The present invention was invented in view of the above-mentioned problems, and has an axle supported horizontally on a bogie frame so as to be rotatable in the horizontal direction. An operating digging member is provided on the truck, and a transmission mechanism is provided between the digging member and the axle for transmitting the operation of the digging member to the axle to rotate the axle in a horizontal direction, and when the truck is running, a transmission mechanism is provided between the digging member and the axle. Excavating parts and transmitters using fluctuations in the relative position of the excavating guide rail and bogie frame! It is characterized by automatically orienting the axle in the normal direction of the running rail through the wheel, thereby preventing squeaks and slips between the wheel and the rail, thereby eliminating the above-mentioned drawbacks.

The illustrated embodiment will be described below.

First, an embodiment shown in FIGS. 1 to 4 will be described. On the ground side, a running mountain rail 1 and an excavation guide rail 2 are laid in parallel thereto.

Axles 4 and 4' are arranged at the front and rear of the lower part of the bogie frame 3, and the front axle 4 is attached to a pin 5 fixed at the lower part on the center line of the bogie frame 3, as shown in FIG. In this case, a friend boss 6 is rotatably supported through a bush 7, and is locked with a nut 9 through a collar 8. The rear axle 4' is also rotatable in the same manner as in the case of the entire front axle 4, with a pin 5' fixed at the lower part of the center line of the bogie frame 3 and a post 6' provided at the center of the rear axle 4'. It is pivoted on. front axle 4
And at both ends of the rear axle 4' are wheels 10a, 10b and 1o'a, 10 that roll on running rails l.

At the front and rear of the lower part of the bogie frame 3, digging members 11*11' are provided for the front and rear axles 4#4', respectively. Front digging member 11
is fixed to the lower part on the center line of the bogie frame 3, and its center portion is rotatably supported by a companion pin 12, and is rotatably provided at both ends of the companion front excavation lever 13 and the third -. As shown, guide rollers 14 & 1 move within the excavation guide rail 2.
It consists of 4b. Similarly, the rear digging member 10' has a pin 12' fixed to the lower part on the center line of the bogie frame 3.
The rear excavation lever 13' is pivotably supported in the center for full rotation.
and guide rollers 14'1Lt14' that are rotatably provided at both ends of the lever 13' and completely roll within the excavation guide rail 2.

'&, 141) and 14'b are guided by the excavation guide rail 2 laid on either side of the traveling rail 1, respectively.

Digging force transmission mechanisms 15, 15' are provided between the axles 4, 4' and the digging members 11, 11', respectively.

The front excavation force transmission mechanism 10 is fixed to the outer periphery of the boss 6 of the front axle 4, is provided integrally with the chain wheel 16 and the front excavation lever 13, and is automatically pivotably supported by the pin 12. chain wheel 1

The rear digging force transmission mechanism 11' is fixed to the boss 6' of the rear axle 4', is provided integrally with the rear digging lever 13', and is rotatably supported by the pin 12'. The gear 20 is in mesh with the gear 19.

Then, by the movement of the truck frame 3, the guide roller 14as14
When the excavation guide rail 2 is guided along the excavation guide rail 2, the excavation lever 13°13' rotates due to the change in the relative position between the rail 2 and the bogie frame 3. The amount of rotation is determined by the gear 17 and chain 1 on the front axle 4.

It can be directed in the normal A-0 direction or in the μA'-U direction.

Therefore, as shown in FIG. 4, the bogie frame 3 is positioned on a straight road (

In the embodiment shown in FIG. 5, a link 21r21' is provided as the digging force transmission mechanism 15, 15', and both ends of the link 21 are pivotally supported on the front digging lever 13 and the axle 4, respectively. The rear excavation lever 13', the axle 4', and the two-link 21/ are all pivoted at both ends, so that the same effects as in the previous embodiment can be achieved.

The excavation guide running rail 2 has a groove shape with walls 22 and 22' formed on both sides, as shown in the cross section of FIG.

Of course, this is not limited to the above mechanism.

As described above, the present invention includes installing an excavation guide rail on at least a curved road in parallel with the running rail, allowing the guide rail to fully rotate the excavation member, and transmitting the axle to the curvature radius of the running rail through the transmission mechanism. Because it rotates horizontally in accordance with the movement of the wheels, there is no creaking or slipping between the wheels and the rails, which improves the durability of the rails and wheels, reduces running resistance, and completely prevents noise generation. It is possible to achieve the following effects.
