And between these 1st, 2nd support | pillars 4 and 5, it connects and provides by the said elevated coupling body 6. FIG.
At this time, an elevated wire or an elevated rail (also referred to as “elevated rail”) can be adopted as the elevated connecting body 6. In this first embodiment, the explanation will be made as an elevated connecting body 6 made of an elevated wire. To do.

The traction mechanism 1 is provided in order to use the elevated connecting body 6 to ascend and tow the slope transport vehicle 2.
The traction mechanism 1 includes a traction mover 7, a pulley means 8, a traction tool 9, and a traction winding means 10.

  That is, the pulling mover 7 uses a pulley structure as shown in FIG. 1 in order to enable movement on the elevated connecting body 6.

The pulley means 8 is connected to the traction moving element 7 via a first connecting arm portion 11 and functions as a fixed pulley, and a second connecting arm portion 13 is connected to the first pulley 12. And a second pulley 14 that functions as a fixed pulley, and a third pulley 15 that is attached to the hill transport vehicle 2 and functions as a moving pulley.
At this time, the position of the first pulley 12 on the traction mover 7 side can be rephrased as an “elevated traction relay point”.

Further, the traction tool 9 may be a traction wire, a traction rope, or the like, and can be selected in consideration of the weight of the towing vehicle 2 to be pulled.
As shown in FIG. 1, the traction tool 9 has one end 9-1 positioned on the first support column 4 side and the other end 9-2 attached to the hill transport vehicle 2 side via the pulley means 8.
At this time, when the traction tool 9 passes through the pulley means 8, the traction tool 9 extending from the one end 9-1 side on the first support column 4 side passes through the first pulley 12 on the traction moving element 7 side. After being wound on the third pulley 15 on the hill transport vehicle 2 side and wound on the second pulley 14 on the traction mover 7 side, the traction tool is attached to the hook 16 provided on the hill transport vehicle 2. The other end 9-2 of 9 is fixed.
In the traction tool 9, a first guide pulley 17 is provided at the tip portion of the first support column 4, and the first guide pulley 17 has a first guide pulley 17 on the side of the traction mover 7 from the traction winding means 10. The middle part extending to the pulley 12 is guided and supported.

  As the traction winding means 10, a manual or electric small winch can be considered. For example, the traction winding means 10 is attached to one end 9-1 side of the traction tool 9, that is, the first support column 4. It is set as the system which winds up the one end 9-1 side of the traction tool 9 provided.

When the hill transport vehicle 2 is lifted and pulled by the traction mechanism 1, the lifting means of the hill transport vehicle 2 is strengthened by providing the pulley means 8 so that the traction mover 7 is moved to the hill transport vehicle 2 side. It is set as the structure which raises and pulls, making it approach.
If it adds, in the traction force of the traction winding means 10 composed of a small winch of the traction mechanism 1, the hill transport vehicle 2 passes through the first pulley 12 which is an elevated traction relay point of the elevated coupling body 6. The first pulley is more powerful than the force A from the traction winding means 10 that is the starting point of traction to the first pulley 12 below the traction mover 7 on the elevated connecting body 6. The traction force B from 12 to the hill transport vehicle 2 is increased by the amount of traction tools 9 multiplexed.
For this reason, the traction force applied to the hill transport vehicle 2 is always pulled by taking into account the force lifted by the first pulley 12 that is the elevated traction relay point on the elevated connecting body 6. It is easy to pass through the slope 3 having stairs and stairs.
The applicant of the present invention performs an actual experiment and confirms that the first pulley 12 which is an elevated towing relay point under the tow moving slider 7 naturally pulls smoothly while approaching the slope transport vehicle 2. I did it.

And a connecting wire 22 that communicates with the rear portion of the slope transport vehicle 2.
At this time, in order to earn the traveling distance of the hill transport vehicle 2 at the height position of the weight 19, in other words, to earn the movable distance of the connecting wire 22, the mounting table 20 is made a “multiple suspension structure”.
The weight of the weight 19 is set in consideration of various conditions such as the weight of the mounting table 20, the operation state in the vertical direction, and the weight of the connection wire 22.

If it adds, first, the said support frame 21 will be formed with the said 2nd support | pillar 5, the other support | pillar 23, and the horizontal support member 24 which connects the 2nd support | pillar 5 and the other support | pillar 23, for example.
Then, the mounting table 20 is attached to the second column 5 and the other column 23 of the support frame 21.
At this time, the mounting table 20 is formed in a U-shaped cross section, for example, and uses the inner space above the bottom 20-1 as a mounting space for the weight 19, while, for example, both the first and second side walls 20-2. , 20-3, a plurality of first and second rolling rollers 20-4 and 20-5 are respectively attached.
Then, the first and second rolling rollers 20-4 and 20-5 are brought into contact with the second column 5 and other columns 23 outside the support frame 21 so that the mounting table 20 can be moved up and down. The configuration.

In addition, a second guide pulley 25 is provided at an intermediate height position of the second support column 5 of the support frame 21, and a plurality of, for example, three first to third support pulleys 26- are provided on the horizontal support member 24. A support side pulley group 26 composed of 1, 26-2, 26-3 is provided.
Furthermore, on the mounting table 20 side, a plurality of, for example, so as to face the support side pulley group 26 and to be positioned between the first to third support side pulleys 26-1, 26-2, 26-3, for example, A moving pulley group 27 including two first and second moving pulleys 27-1 and 27-2 is provided.

Then, after fixing one end of the connection wire 22 to the rear part of the hill transport vehicle 2, the connection wire 22 is wound around the second guide pulley 25 and wound around the first support side pulley 26-1 of the support side pulley group 26.
After winding on the first support side pulley 26-1, the support side pulley group 26 and the moving side pulley group 27 are alternately wound, that is, from the first support side pulley 26-1 to the first. The moving side pulley 27-1, the second supporting side pulley 26-2, the second moving side pulley 27-2, and the third supporting side pulley 26-3 are sequentially wound, and the other end of the connection wire 22 is placed on the mounting table 20 described above. Is fixed to the bottom portion 20-1, and the above-described “multiple suspension structure” is realized.

  The lowering means 18 having the “multiple suspension structure” functions not only when the hill transport vehicle 2 is lowered, but also ensures the stability of the travel position when the hill transport vehicle 2 is lowered, as well as the hill transport. Since it functions even when the vehicle 2 is lifted and pulled, it also ensures the stability of the traveling position when the hill transport vehicle 2 is pulled and pulled.

  Next, the operation will be described.

When the hill transport vehicle 2 is lifted and pulled, the traction winding means 10 composed of a small winch of the traction mechanism 1 provided on the first support column 4 located near the upper end of the hill 3 is driven, The one end 9-1 side of the traction tool 9 is wound up.
By the winding operation of the traction tool 9 by the traction winding means 10, the traction force is transmitted to the position of the first pulley 12 which is the “elevated traction relay point” on the traction moving element 7 side.
At this time, in the traction force of the traction winding means 10, the force that lifts and pulls the hill transport vehicle 2 via the first pulley 12 that is the elevated traction relay point of the elevated connecting body 6 is the starting point of traction. The traction force from the first pulley 12 to the hill transport vehicle 2 is greater than the force A from the traction winding means 10 to the first pulley 12 below the traction mover 7 on the elevated connecting body 6. Since B increases as much as the traction tool 9 is multiplexed, the traction force applied to the hill transport vehicle 2 is always lifted by the first pulley 12 which is the elevated traction relay point on the elevated connecting body 6. It is towed with the added power.
That is, the first pulley 12 which is an elevated towing relay point under the towing moving element 7 is smoothly pulled while naturally approaching the hill transport vehicle 2 in consideration of its own weight and the like.

  In addition, the lowering means 18 having a “multiple suspension structure” when the hill transport vehicle 2 is lifted and pulled is such that the connecting wire 22 is pulled out from the support frame 21 side by the traction force, and the mounting table 20 is raised. The stability of the traveling position when the hill transport vehicle 2 is lifted and pulled is ensured.

When the hill transport vehicle 2 is lowered, the loading function of the pulling winding means 10 is released so that the weight 19 placed on the loading table 20 of the lowering means 18 is caused by its own weight. 20 is moved downward, the lowering means 18 pulls the other end of the connection wire 22, and the pulling tool 9 that has been wound up from the pulling winding means 10 is pulled out, The descending operation of the hill transport vehicle 2 is started.
At this time, the lowering means 18 having the “multiple suspension structure” functions when the slope transport vehicle 2 is lowered to ensure the stability of the traveling position when the slope transport vehicle 2 is lowered.

Thus, in the traction mechanism 1 of the hill transport vehicle 2 that lifts and pulls the hill transport vehicle 2 on the hill 3 by the traction tool traction tool 9, the first support column 4 is provided in the vicinity of the upper end of the hill 3 and the lower end of the hill 3. The traction mechanism 1 is provided with a second support column 5 in the vicinity, an elevated connection body 6 that communicates between the first and second support columns 4 and 5, and the hill transport vehicle 2 is lifted and pulled using the elevated connection body 6. The traction mechanism 1 includes a traction mover 7 that moves on the elevated connecting body 6, a pulley means 8 that is attached to the traction mover 7 and the hill transport vehicle 2, and one end 9-1. A traction tool 9 that is positioned on the first support column 4 side and has the other end 9-2 attached to the hill carriage 2 side via the pulley means 8, and a traction winding means provided on one end 9-1 of the traction tool 9 10 and when the tractor 1 pulls up the hill transport vehicle 2 by the traction mechanism 1 By providing the pulley means 8 has a configuration to increase traction while approaching the lifting force traction moving element 7 to strengthen the slope trucks 2 on slope truck 2 side.
Accordingly, when the hill transport vehicle 2 is lifted and pulled by the traction mechanism 1, the lifting effect of the hill transport vehicle 2 is improved by pulling the traction mover 7 while approaching the hill transport vehicle 2 side. It is possible to facilitate the progress of the slope 3 including the step of the slope transport vehicle 2, which is practically advantageous.
Further, the traction mechanism 1 having the traction winding means 10 and the like can be reduced in weight, and the configuration of the traction mechanism 1 can be simplified, which can reduce the manufacturing cost and is economically advantageous. It is.

Further, the traction mechanism 1 is provided with a lowering means 18 for lowering the hill transport vehicle 2, and the lowering means 18 has a “multiple suspending structure”, so that when the hill transport vehicle 2 is lowered, a “multiple suspension” is provided. The descending means 18 of the “structure” can function to ensure the stability of the traveling position when the hill transport vehicle 2 is lowered, and the descending means 18 of the “multiple suspension structure” can be used when the hill transport vehicle 2 is pulled up and pulled. Can also ensure the stability of the traveling position when the hill transport vehicle 2 is pulled up and pulled.
Note that it is also possible to use a miniature traction machine with a relaxation prevention function (torque converter) that operates in conjunction with the traction winding means 10 instead of the descending means 18 of the “multiple suspension structure”.

The slope transport vehicle 2 is installed at a lower end portion of the slope 3 that can reach a preset position.

And between these 1st, 2nd support | pillars 4 and 5, it connects and provides by the said elevated coupling body 6. FIG.
At this time, an elevated wire or an elevated rail (also referred to as an “elevated rail”) can be considered as the elevated connecting body 6. In the second embodiment, an elevated wire is used as in the first embodiment. It will be described as an elevated connecting body 6 made of

The traction mechanism 31 is provided in order to ascend and tow the slope transport vehicle 2 using the elevated connecting body 6.
The traction mechanism 31 includes a traction mover 7, a pulley means 32, a traction tool 33, and a hand feeding means 34.
In other words, the pulling mover 7 uses a pulley structure as shown in FIG. 2 in order to enable movement on the elevated connecting body 6.

Further, the pulley means 32 is connected to the traction moving element 7 via the first connecting arm portion 11 and functions as a fixed pulley. 37, a small pulley 38 that is provided coaxially with the large pulley 37 and functions as a constant pulley having a smaller diameter than the large pulley 37, and the slope transport vehicle 2 side.

Therefore, it becomes easy to pass through the slope 3 having steps, stairs and the like.

  Further, the traction mechanism 31 has a method in which the hand-drawing means 34 is rotated forward (in the upward traction direction) or reversely (in the downward direction) by the electric motor 35 of the drive wheel 36 provided in the hill transport vehicle 2. In addition to the function of ascending and pulling the hill transport vehicle 2, the hill transport vehicle 2 also has a function as a lowering means when lowering the hill transport vehicle 2.

If the postscript is added, the thing of this 2nd execution example has provided the power of going up and down on the said slope transport vehicle 2 side, and implement | achieved the concept to drive | operate on the slope transport vehicle 2, and the elevated connection which consists of an elevated wire A travel guide chain and a toothed belt from the large pulley 37 and the small pulley 38, which are elevated towing relay points suspended on a towing mover 7 that can move naturally on the body 6, to the towed portion of the hill transport vehicle 2 The point that the traction tool 33 such as a travel guide wire subjected to anti-slip processing or a travel guide rope subjected to anti-slip processing is folded back to increase the traction force (lifting force) during this time is the same as in the first embodiment. It is the same.
The second embodiment is not towed from the top of the hill 3 but is powered by the power provided on the hill transport vehicle 2 side by a traction tool 33 that is used as a scaffold for traveling towing from the top to the bottom of the hill 3. It is a means to bring it in, and it is configured to move up and down by moving the hill carriage 2.
At this time, if the traction tool 33 is squeezed by the squeezing means 34 on the hill transport vehicle 2 side, no force of movement is applied to the naturally movable traction mover 7. The positions of the large pulley 37 and the small pulley 38 do not move at all, and only the lifting force of the slope transport vehicle 2 is applied.
Therefore, a large pulley 37 having a long circumference (large diameter) and a short circumference (small diameter) are provided at an elevated traction relay point that is lifted by a traction mover 7 that can move naturally on the elevated connecting body 6 made of an elevated wire. A pulley structure in which the small pulley 38 is fixed coaxially is attached, and the traction tool 33 from the elevated towing relay point to the towed portion of the hill transport vehicle 2 is folded back and pulled.
For this reason, paying attention to the movement of the large pulley 37 and the small pulley 38 and pulling the traction tool 33 by hand, the large pulley 37 rotates. Therefore, the small pulley 38 that is coaxial with the movement of the large pulley 37 is moved. The traction mover 7 that can move naturally is moved to move the elevated traction relay point.
The amount of movement of the elevated towing relay point can be adjusted by adjusting the size ratio (such as “circumference ratio” or “diameter ratio”) of the large pulley 37 and the small pulley 38.

In other words, the traction tool 33 stretched as a scaffold for traveling towing from the top to the bottom of the hill 3 is moved by the urging means 34 provided on the hill transport vehicle 2 side, so that the hill transport vehicle 2 is moved up and down. The configuration is realized.
Further, a pulley structure in which a large pulley 37 and a small pulley 38 are coaxially fixed is attached to an elevated traction relay point portion suspended on a traction mover 7 that can move naturally on an elevated connecting body 6 made of an elevated wire, and The structure which provided the 3rd pulley 15 and the drive wheel 36 in the towed part of the slope transport vehicle 2 is implement | achieved.
Then, the traction tool 33 having one end 33-1 fixed to the first support column 4 at the upper end of the hill 3 is routed through the third pulley 15 attached to the hill transport vehicle 2 via the small pulley 38 at the elevated traction relay point. And after passing through the large pulley 37 of the elevated towing relay point, further turning back and acting on the drive wheel 36 attached to the hill transport vehicle 2, via the lower part of the hill transport vehicle 2, After passing through the fourth pulley 39 attached to the lower part of the second pillar 5 at the lower end and the fifth and sixth pulleys 40 and 41 on the upper part of the second pillar 5, the other end 33-2 of the traction tool 33 is relaxed. A prevention weight 42 is connected.

For this reason, when the electric motor 35 of the hill transport vehicle 2 is operated and the traction tool 33 is engulfed by the drive wheel 36 and the traction tool 33 is pulled down, the large pulley 37 rotates and the coaxial small pulley 38 also rotates, and the hill transport The car 2 is lifted and pulled and proceeds upward.
At this time, the traction tool 33 does not move from the one end 33-1 fixed to the first support column 4 at the upper end of the hill 3 to the elevated traction relay point suspended on the traction mover 7 that can move naturally, and the elevated traction relay. From the point, the slope transport vehicle 2 moves by being dragged toward the drive wheels 36 by the amount that the drive wheels 36 of the slope transport vehicle 2 are multiplexed.
Then, since the large pulley 37 is moved, the coaxial small pulley 38 is also moved, and the elevated traction relay point is moved to the first column 4 side at the upper end of the slope 3.

Further, the traction tool 33 between the drive wheels 36 attached to the hill carriage 2 from the small pulley 38 at the elevated traction relay point is multiplexed in order to increase the lifting force to the elevated connecting body 6 made of an elevated wire. Because of this, the momentum is large, and the small pulley 37 that the traction tool 33 of the corresponding part touches, and the traction tool 33 between the first support pillar 4 that remains as a single line without being multiplexed and the elevated traction relay point contact each other. If the size of the pulley 38 is the same, the momentum of the elevated traction relay point will be the same, and the elevated traction relay point will move to the first column 4 side at a high speed, and the lifting effect to the elevated coupling body 6 side will be lost. It becomes impossible to pass through steps and stairs.
At this time, in order to adjust the travel difference between the two, the ratio of the size of the large pulley 37 and the small pulley 38 of the coaxial double pulley structure is set to about the multiplexing ratio of the traction tool 33, and the elevated traction relay point is moved. Can be adjusted to an appropriate speed.

In other words, since the tractor 33 of the multiplexed part is pulled faster than the ground speed of the hill transport vehicle 2, if the distance between the first support column 4 and the elevated traction relay point is shortened at the same speed as the multiplexed part. Since the elevated towing relay point is too close to the first support column 4 side, the lifting effect on the elevated connecting body 6 made of the elevated wire of the traveling vehicle 2 traveling on the slope is lost, and the towing effect from the elevated connecting body 6 is lost. End up.
For this reason, the difference in movement of the traction tool 33 (also referred to as “multiplexing ratio”) due to multiplexing between the elevated traction relay point and the drive wheel 36 is eliminated by the difference in the size of the coaxial double pulley structure, for example, the circumferential difference. To do.

Thus, in the traction mechanism 31 of the hill transport vehicle 2 that lifts and pulls the hill transport vehicle 2 on the hill 3 by the traction tool 33, the first support column 4 is provided near the upper end of the hill 3 and the lower end of the hill 3 is positioned near the lower end. The second support column 5 is provided, the elevated connecting body 6 that communicates between the first and second support columns 4 and 5 is provided, and the traction mechanism 31 that ascends and pulls the hill transport vehicle 2 using the elevated connection body 6 is provided. The mechanism 31 includes a pulling mover 7 that moves on the elevated connecting body 6, a pulley means 32 that is attached to the pulling mover 7 and the hill transport vehicle 2, and one end 33-1 on the first support column 4 side. While the other end 33-2 is provided on the second support column 5 side via the pulley means 32, and the hand feeding means for winding the traction tool 33 by winding the intermediate portion of the traction tool 33. 34 and is transported on the slope by the traction mechanism 31. When increased pulling the 2 was configured to increase traction while approaching the traction moving element 7 to slope trucks 2 side by providing the pulley means 32.
Therefore, when the hill transport vehicle 2 is lifted and pulled by the traction mechanism 31, the traction moving element 7 is lifted and pulled while approaching the hill transport vehicle 2 side, and the lifting effect of the hill transport vehicle 2 is improved. It is possible to facilitate the progress of the slope 3 including the step of the slope transport vehicle 2, which is practically advantageous.

  Further, it is possible to reduce the weight of the traction mechanism 31 having the hand feeding means 34 and the like, and to simplify the configuration of the traction mechanism 31, which can reduce the manufacturing cost, which is economically advantageous.

  Further, the traction mechanism 31 has a method in which the hand-drawing means 34 is rotated forward (in the upward traction direction) or reversely (in the downward direction) by the electric motor 35 of the drive wheel 36 provided in the hill transport vehicle 2. In addition to the function of ascending and descending the hill transport vehicle 2, it also has a function as a lowering means when lowering the hill transport vehicle 2, which can contribute to improved usability.
