Description

The present invention relates to a carriage.

In many cases, only a work space large enough for one person to walk through can be secured at places where block walls are installed, and it is often the case that carts cannot be used to transport heavy materials such as mortar generated during the installation process. In that case, if there is a detour route, it is possible to take a detour and transport it with a trolley, but if there is no detour route, the only way to divide the materials into small pieces and carry them manually is to use a transportation tool that can be used in narrow spaces. and
Considering the limitation of work space, a single-rail truck using the block wall itself as a rail is the most effective.

In addition, as a vehicle of this type, Patent Document 1 shows a straddle-type monorail in which running tires and horizontal tires are arranged on a track girder, and Patent Document 2 shows an example of a transport vehicle in which square steel pipes are wound with rollers. However, none of them can be applied to the dimensional accuracy of the rail block described above.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the rail-type bogie of the present invention will be described in detail below with reference to the drawings.

First, the configuration of the single-track bogie will be described with reference to FIGS. 1, 2 and 3. FIG.
A single-track bogie is constructed by attaching running wheels, fixed guide wheels, stability wheels, oscillating guide wheels and stability wheels to a bogie frame consisting of a loading platform frame, first to fourth wheel frames and a support frame. be.

Next, the details will be described.
The loading platform frame 1 has a rectangular frame as shown in FIG. It is installed in the form of a “gate”. A first wheel frame 2 provided with horizontal shaft holes 2-1, 2-2 and vertical shaft holes 2-3, 2-4 and a second wheel frame provided with vertical shaft holes 3-1, 3-2 are attached to the cargo bed frame. A set of two wheel frames 3, a third wheel frame 4 with horizontal shaft holes 4-1 and 4-2 and a swing shaft hole 4-3, a swing shaft hole 5-1 and a screw hole 5-2 are attached. A bogie frame 50 is constructed by horizontally mounting a set of the fourth wheel frame 5 on the struts 6a and 6c and on the struts 6b and 6d.
Then, the axle 8 is inserted through the horizontal shaft hole 2-1 of the first wheel frame 2 and the horizontal shaft hole 4-1 of the third wheel shaft 4 in the order of the pipe 10, the running wheel 7a, the pipe 9, the running wheel 7b and the pipe 10. Then, the running wheels 7a and 7b are rotatable, and both ends of the shaft are fixed. Similarly, the pipe 10, the running wheel 7c, the pipe 9, the running wheel 7d, and the pipe 10 are inserted through the horizontal shaft hole 2-2 and the horizontal shaft hole 4-2 in this order, and the running wheels 7c and 7d are also attached. .
Next, the axle 13 is inserted through the vertical axle hole 2-3 of the first wheel frame 2 and the vertical axle hole 3-1 of the second wheel frame 3 in the order of the wheel 12a, the pipe 14, the wheel 11a and the pipe 15, and the wheel 11a is mounted. , 12a are rotatable and fixed at both ends of the shaft. Similarly, wheels 11b and 12b are also attached by inserting axle 13 in order of wheel 12b, pipe 14, wheel 11b and pipe 15 through vertical shaft hole 2-4 and vertical shaft hole 3-2. The axles 8, 13 and the pipes 9, 10, 14, 15 have the same shape and the same reference numerals.
Further, the swing shaft 23 is inserted into the swing shaft hole 4-3 of the third wheel frame 4 on the opposite side, and the swing shaft 24 is inserted into the swing shaft hole 5-1 of the fourth wheel frame 5, so that the swing frame 16 is mounted. attached to the
In this state, the oscillating guide wheel 17, the pipe 20 fitted with the elastic body 21, and the oscillating stabilizer wheel 18 are inserted in the order of the wheel shaft 19, and the oscillating stabilizer wheel is inserted into the long hole 16-1 of the oscillating frame. 17 and oscillating guide wheels 18 are fixed at both ends of the axle so as to be rotatable and rotatable.
The other end of the elastic body is connected to a pin 22 attached to the fourth wheel frame to rotate the oscillating guide wheel 17 and the oscillating stabilizer wheel 18 toward the rail. At this time, the rotating end is configured to be regulated by the stop plate 16-2. By screwing the stop plate into the screw hole 5-2 attached to the fourth wheel frame 5, it is also possible to stop the rocking movement.

Next, FIGS. 4, 5, 6 and 7 show a state in which the single-track type bogie 100 and the rail 80 are combined with respect to the setting and operation of the swing frame 16, the swing guide wheel 17 and the swing stability wheel 18. will be described with reference to
First, the setting will be explained.
The swinging end of the swinging frame 16 toward the rail is slightly rotated toward the rail from the position where the outer peripheries of the swinging guide ring 17 and the swinging stabilizer ring 18 contact the side surface of the rail 80 . A stop plate 16-2 attached to the moving frame is set.
At this time, the contact position between the outer circumference of the wheel and the rail 80 can also be adjusted by the elongated hole 16-1 attached to the swing frame 16. The line connecting the center of the swing shaft 23 and the center of the axle 19 The angle with the rail can also be set.
This is because the smaller the rotation angle of the swing frame, the greater the force that supports the tilt of the rail-type bogie in the horizontal direction, but conversely, the force with which the projections 90 and 91 lift the swing frame 16 decreases. It is a supplement and a function to adjust the balance according to the conditions of the rail and the load.

Next, operation will be described.
When the single track type carriage 100 is driven upward in FIG. 5 and either the oscillating guide wheel 17 or the oscillating stabilizer wheel 18 comes into contact with the projection 90 on the oscillating frame 16 side, the projection causes the above-described movement. A force is generated in the direction of lifting the oscillating guide wheel or the oscillating stability wheel.
Then, the elastic body 21 is pulled by the action of force, the swing frame 16 is rotated clockwise, the swing guide wheel or the swing stabilizer wheel rides on the projection, and the single rail type When the cart is driven and reaches the top of the projection 90, the state shown in FIG. 6 is obtained.
After that, when the guide ring or the stabilizer ring passes the projection, the swing frame 16 is rotated counterclockwise by the force of the elastic body 21 to return to the state without the projection as shown in FIG.
7, if there is a protrusion 91 on the side of the fixed guide wheel 11 and the fixed stabilizer wheel 12, when either the fixed guide wheel or the fixed stabilizer wheel comes into contact with the protrusion, the above-described A force is generated that pushes the fixed guide wheels or the fixed stabilizer wheels outwardly of the rail 80 . This force is transmitted to the swinging frame 16 on the opposite surface, pulls the elastic body 21 in the same manner as described above, and rotates the swinging frame clockwise to move the swinging guide wheel 17 and the swinging stabilizer wheel 18. When it moves outward and passes through, it returns to the state without projections as shown in FIG.
As described above, the rocking frame absorbs any projections on either side of the rail and travels.

Next, as an example of an embodiment, a mode of use in which the single-track type truck of the present invention is set on a block wall with poor running conditions and materials are transported will be described with reference to FIGS. 8 and 9. FIG.
A loading platform 60 with a guard is fixed to the loading platform frame 1 of the single-track bogie 100 by passing bolts (no reference numerals) through screw holes 1-1 provided in the loading platform frame. In this state, the block wall 200 is sandwiched between the fixed guide wheel 11 and the fixed stabilizer wheel 12, and the rocking guide wheel 17 and rocker wheel 18, and the running wheel 7 is set on the block wall. Then, a bucket 70 filled with materials such as mortar is put on the loading platform, and the state shown in FIGS. 8 and 9 is obtained.
When the single-rail truck 100 is pushed and pulled, the block wall 200 is formed while the fixed guide wheels and the fixed stabilizer wheels, and the rocking guide wheels and the rocking stabilizer wheels are in close contact with the sides of the concrete block wall. run along.
However, when the block wall comes into contact with the projection 90 shown in FIG. 6 or the projection 91 shown in FIG. When the stabilizer wheel 18 rotates away from the block wall and crosses the projection, it returns. While repeating this, the robot travels along the wall made of blocks 200. - 特許庁
As described above, it is possible to travel without tilting the cargo bed by absorbing the unevenness of the wall made of blocks and the slight difference in level. This can be expected as an effective means to solve the problem of material transportation that occurs when installing a block wall.
