In such a suspension vehicle for a moving wall, wheels are respectively provided on four sides of a suspension vehicle main body having a substantially square shape in a plan view, and a suspension member for suspending the mobile wall is vertically provided at the center of the suspension vehicle main body. As shown in FIG. 3 and FIG. 7 (b), the hanging position of the moving wall can be freely changed by traveling in a hanger rail having a substantially C-shaped cross section.

[Problems to be Solved by the Invention]

In such a conventional suspension vehicle for a moving wall, since the suspension member is suspended in the center of the suspension vehicle main body as described above, the structure of the hanger rail is inevitably C-shaped in cross section as described above. .

Since the hanger rail on which the hoisting vehicle travels as described above is laid vertically and horizontally on the ceiling according to the degree of freedom of the hoisting vehicle, the unit price greatly affects the price of the entire moving wall. In this respect, since the hanger rail having a substantially C-shaped cross section as described above has to be custom-made due to its special shape,
There is a drawback that the price of the entire moving wall becomes extremely expensive.

From such a point, attempts have recently been made to construct the hanger rail from a commercially available mold steel. However, in order to suspend a large moving wall as described above, it is necessary to have sufficient strength in consideration of the load balance, and the present invention uses H-section steel as a hanger rail from such a viewpoint. It is intended to provide a suspension vehicle for a moving wall, which can exhibit sufficient strength when there is a problem.

Therefore, the purpose of the present invention is to reduce the cost of the entire moving wall by using a commercially available H-shaped steel and to be suitable for traveling along the hanger rail composed of the H-shaped steel. The purpose of the present invention is to provide a suspension vehicle for moving walls having high strength.

[Means for Solving the Problems]

In order to achieve the above object, the main means adopted by the present invention is a moving wall suspension vehicle for an H-shaped hanger rail, which is made of H-shaped steel and whose left and right upper surfaces of one flange portion are used as horizontal running surfaces of the rail. In the above, a horizontal member to which a hanging member for the moving wall is vertically attached, vertical members fixed to both ends of the horizontal member, and three vertical members are arranged inside the vertical members along the traveling direction of the suspension vehicle. A total of six wheels rolling on the horizontal running surface and front and rear mounting parts projecting from the upper ends of the front and rear end parts of the above-mentioned vertical members toward the center of the suspension vehicle are provided in different steps on the left and right sides. A total of four upper guide wheels rolling on the web of the hanger rail, a guide rail provided on the lower surface of the flange portion having the running surface of the H-shaped rail, and the horizontal member for rolling contact with the hanger guide rail. A lower guide wheels and suspending a moving wall vehicle and said point consisting comprises a provided between the wheels.

[Action]

As described above, according to the present invention, one flange portion of the hanger rail made of H-shaped steel is surrounded by the horizontal member and the vertical member, and each of the three wheels provided on both vertical members has the flange portion. Since the rolling contact is evenly applied to the left and right of the hanger rail, a balanced load is maintained without exerting a biased force on the hanger rail, and a high-strength suspension vehicle is provided.

A moving wall (not shown) is suspended on the suspension vehicle 1 by a suspension member 3 such as a suspension bolt. The suspension member 3 is rotatably attached to a horizontal member 4 which is a component of the suspension vehicle 1 by a thrust bearing 5.

Both ends of the horizontal member 4 have left and right vertical members 7 formed by flange portions of a suspension vehicle body 6 made of H-shaped steel.
It is secured to _{a, 7 b.}

The inner side of the vertical members _{7 a} and _{7 b,} respectively, via the bracket 8, respectively three wheels _{9 a, 9 b, 9 c} ( left and right total of six) is rotatably mounted, respectively. Of the three wheels _{9 a, 9 b, 9 c} of the one side, in the middle of the wheel largest diameter, left and right wheels ₉ b, _{9 c} is configured to a small diameter. The six wheels 9 _a , 9 _a , 9 _b , 9 _b ,
All of 9 _c and 9 _c are mounted at a height such that they can be in rolling contact with the upper surfaces 2 _a and 2 _b, which are horizontal traveling surfaces of the hanger rail H, at the same time.

At the upper end of the front and rear ends of the bracket 8 which constitutes a part of the vertical members 7 _a and 7 _b, the attachment portion 10 _a and 10 _b is formed to project toward the center of the Tsukuruma 1, one of the brackets 8 the mounting portion 10 _a and 10 _b, via a shaft 11 _a projecting upward from the mounting portion 10 _a and 10 _b, the guide wheels _{12 a, 12} a are attached. In addition, the mounting portion ₁₀ a, 10 _b projecting from the other of the bracket 8, these attachment portions 10 _a and 10 _b
The guide wheels 12 _b and 12 _b are rotatably attached via shafts 11 _b and 11 _b protruding further downward.

Thus, the upper guide wheel 12 _b mounted on the upper guide wheel 12 _a and the other bracket 8 attached to one bracket 8 side is provided on different levels in the vertical direction. Further, the horizontal distance between the axis 11 _a and 11 _b, as with the guide wheel 12 _a and 12 _b are in contact rolling on left and right sides of Ueppu portion W of the hanger rail H as shown in FIG. 6 It is set.

The moving wall is suspended by the subordinate member 3 via, and the moving wall is carried by the traveling of the suspension vehicle 1. At this time, the left and right upper guide wheels 12 _a , 12 _a , 12 _b , and 12 _b are both
It rolls on the side surface of the web portion W of the hanger rail 1 to maintain the straight traveling state of the moving wall. In this case, if the linear guide rails 17 _a and 17 _b are attached to the lower surface of the hanger rail H so as to be in rolling contact with the lower guide wheel 15, the inclination of the suspension vehicle 1 is restricted thereby, and the moving wall is transported. The condition becomes more stable. However, in the straight portion of the mobile wall, so stable running condition of the Tsukuruma 1 by the upper guide wheels 12 _a, 12 _b are fully maintained, usually, in a portion of the straight hanger rail H, the guide rail 1
_7a and _17b are omitted.

Next, the bending traveling state of the suspension vehicle 1 and the straight traveling or bending traveling state at the branch portion will be described with reference to FIGS. 7 and 8.

Clothes rail H, the connecting portion 18 _a, as shown in FIG. 7
A bent rail can be obtained by connecting the ends via the. Such connection portion 18 _a is the cross-sectional shape is the same as the conventional hanger rail H, 7
As shown in the figure, it differs from a normal straight-moving hanger rail in that it is bent in an arc shape in its planar state. As shown in FIG. 7, guide rails _17a and _17b are usually provided on the lower surface of the bent portion of such a hanger rail. Lower guide wheels 15 of the mobile wall 1 thereby has traveled as indicated by arrow 19 when approaching to the connecting portion 18 _a, first rolling contact with the outer side of the guide rail 17 _b. As a result, tilting of the suspension vehicle 1 due to the inertial force of the moving wall is prevented, and a stable traveling state is obtained.

When Tsukuruma 1 progresses in the direction indicated by the arrow 19, it reaches the position shown eventually by solid lines lower guide wheels 15, wherein the lower guide wheels 15 rolling against the inner side of the guide rail 17 _a, progresses further If, rolling contact 17 again outside of the guide rail _b, thereby the inclination of Tsukuruma 1 is prevented.

Even in such a bending traveling state, the upper guide wheel 1
Since 2 _a and 12 _b are rolling contact with the side surface of the web portion W of the hanger rail H consistently, Tsukuruma 1 is guided, and its inclination can be prevented.

The hanger rail H is further provided with a connecting portion 18 as shown in FIG.
By being connected via _b , it is connected to the branch-side hanger rail. In the connecting portion 18 _b, web portion W
Is cut out at the position of the end portion 20 shown in FIG. 6, and only the vertical guide piece 21 is suspended from the upper flange portion F ₂ . Such a vertical guide piece 21 is bent in the direction of the branch rail as shown in FIG. 8, which enables a special traveling state as described below.

That is, consider the case where the suspension vehicle 1 has traveled along the arrow 22 in FIG. Here, when the upper guide wheel 12 _a (upper side) is on the right side of the web W and the connecting portion 18 _b is bent rightward as shown in the drawing, the upper guide wheel 12 _a is removed from the web portion W. Vertical guide piece 21
Contact subsequently rolling the, thereby advancing direction of Tsukuruma 1 is deflected to the right, Tsukuruma as indicated by arrow 22 _a goes possessed the branch side clothes rail H _1. At this time, the notch 23 _a is formed so that the left vertical member 7 _a does not interfere with the straight-movement hanger rail H ₂ . Here, inside the vertical guide piece 21 of the connecting portion _18b ,
Since the guide rail 17 _b is attached, the lower guide wheels 15 by rolling contact with the guide rail 17 _b, the inclination of Tsukuruma is prevented.

On the contrary, even when the suspension vehicle moves from the branch-side hanger rail H ₁ to the straight-side hanger rail H via the connecting portion 18 _b , the upper guide wheel 12 _a on the upper end side provides a smooth bending traveling state. .

Then, through the connecting portion 18 _b from the straight hanger rail H, Tsukuruma the straight hanger rail H ₂ a description will be given of a case go possessed. In this case, the upper guide wheel 12 _a of the upper side is used instead of 180 degrees the direction of Tsukuruma 1 to be placed on the left side of the web portion W. Thus, the upper guide wheel 12 _b of the lower side is disposed on the right side of the web portion W. Due to such arrangement of the upper guide wheels 12 _a and 12 _b , the upper guide wheel 12 _b on the lower stage side has the suspension vehicle connected to the connecting portion 18 _b.
When approaching, the end 20 of the vertical guide piece 21
Since it passes below the guide wheels _12a and 1
2 _b are both eliminated rolling contact with the web portion W and the vertical guide piece 21, Tsukuruma 1 as it is kept in the straight state, it goes possessed the connecting portion 18 _b in the straight hanger rail H _2. At this time, the right side in the traveling direction of the vertical member 7 _a is divided by notches 23 _b to the connecting portion 18 _b so as not to interfere with the hanger rail H and branched hanger rail H _1.

Similar operation is realized even when possess from the hanger rail of H ₂ for straight in the straight hanger rail H through the connecting portion 18 _b.

In the above embodiment, the wheel 9 _a large diameter provided at the center (barycentric position) of the moving wall, since the wheels 9 _b and 9 _c of the right and left is small, the load applied to the Tsukuruma 1 most acts on the wheel 9 _a large diameter, when the Tsukuruma changes the traveling direction, car hanging about said central wheel 9 _a can be changed easily its direction of travel.

Further, since the wheels 9 _a to 9 _c as shown in the above examples is constructed by the three central and before and after, even when crossing the notch 23 _a or 23 _b as described above, the 3
Since pieces of the wheel _{9 a,} 9 b, ₉ a center of the wheel _{9 a} or the front and rear wheels _{9 b} and _{9 c} of the _c is in contact rolling always on the running surface of the hanger rail, Tsukuruma 1 cutout 23 _a Or 2
Fell into 3 _b, it is avoided inconveniences such large impact on Tsukuruma 1.
