DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is an improvement of a moving vehicle suspension vehicle for suspending a moving wall for freely partitioning a museum, exhibition hall, conference room, etc. from a ceiling surface. The present invention relates to a suspension vehicle for a moving wall, which is suitable for suspending a large moving wall that weighs several tons and has stable traveling performance.

[Prior art]

An example of a suspension vehicle for a moving wall is, for example, JP-A-61-2.
The one disclosed in Japanese Patent No. 90180 is known. 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. .

The above-mentioned hanger rail on which the hoisting vehicle travels is laid vertically and horizontally on the ceiling according to the degree of freedom of the hoisting vehicle, so that the unit 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 6 wheels that roll on the horizontal running surface, and a total of 4 tops that are provided on the upper and lower ends of the front and rear ends of the above vertical members so as to roll on the web of an H-shaped hanger rail With a guide wheel,
An auxiliary support member fixed to at least one of the vertical members and having an inverted L-shaped cross section that rolls over a plurality of ball bearings on the upper surface of the rolling contact plate provided at the branch portion of the H-shaped rail; A guide rail provided on a lower surface of a flange portion having a traveling surface of the rail, and a lower guide wheel provided between the horizontal member and the wheel for rolling contact with the guide rail. It is a suspension vehicle for moving walls.

[Operation] As described above, in 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. Since the rolling contact with the left and right sides of the flange portion is made with an even force, the load balance is maintained without exerting a biased force on the hanger rail, and a suspension vehicle with high strength is provided.

Further, the hoisting vehicle of the present invention is provided with an auxiliary supporting member, and the auxiliary supporting member is mounted on the ball bearing of the rolling contact plate just before the hoisting vehicle approaches the branch portion of the H-shaped rail. The wheels of the hoisting vehicle are slightly raised from the horizontal running surface of the H-shaped rail, and are passed through the branch portion of the H-shaped rail. Then, after the suspension vehicle has passed through the branch portion, the auxiliary support member is disengaged from the ball bearing of the rolling contact plate, and the wheel is moved to the H level.
By returning to the horizontal running surface of the mold rail, the suspension vehicle can be run again along the H-shaped rail.

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 are H-shaped suspension vehicle main bodies 6
It is fixed to the left and right vertical members 7 _a, 7 _b corresponding to the flange portion.

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. It said one side of the three wheels _{9 a,} 9 b, ₉ out of _c, at the center of the wheel _{9 a} is 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.

The bracket 8 forming a part of the vertical members 7 _a and 7 _b has an upper guide wheel via guide axles 11 _a , 11 _a , 11 _b , 11 _b at the upper ends of the front and rear ends of the bracket 8. _{12 a, 12 a, 12 b} , 12 mounting member _b is attached ₁₀ a, 10 _b are fixed.

The guide axle 11 _a and the guide axle 11 _b have different lengths, and the guide axle 11 _a is the guide axle 11 a.
It is set longer than _b .

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 guide axle 11 _a and 11 _b are such that the upper guide wheels 12 _a and 12 _b rolling contact on the left and right sides of the web portion W of the hanger rail H as shown in FIG. 1 Is set to.

In at least one of the vertical members 7 _a, 7 _b are cross-sectional shape is fixed the inverted L-shaped auxiliary support member 25. The auxiliary support member 25 supports the hoisting vehicle 1 in a lifted state at a branch portion of a hanger rail H, which will be described later in detail, so that the hoisting vehicle 1 can smoothly pass through the branch portion. belongs to.

A lower guide wheel 15 is rotatably attached via a vertical shaft 14 to the central portion of the horizontal member 13, which corresponds to the web portion of the suspension vehicle body 6. Then, the hanger rail H of the lower surface 16, the lower guide wheels 15 rolling in contact with left and right guide rails 17 _a, 17 _b are mounted as necessary. If necessary, only one of the guide rails 17 _a and 17 _b may be attached.

When the suspension vehicle 1 as described above travels along the linear hanger rail H, each of the left and right three wheels 9 _a , 9 _b ,
9 _c are flange portions F ₁ and F of the hanger rail H, respectively.
_2, the upper surface 2 _a and the upper surface 2 _b of the horizontal rolling member 4 are rotatably contacted with each other as shown in FIG.
The moving wall is suspended by the hanging member 3 via the, 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 of the hanger rail H will be described with reference to FIGS. 5 and 6.

Clothes rail H, the connecting portion 18 _a as shown in FIG. 5
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, 5
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. 5, guide rails _17a and _17b are usually provided on the lower surface of the bent portion of the hanger rail. Thus when the lower guide wheels 15 of Tsukuruma 1 that has traveled as indicated by arrow 19 that 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 further 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, further progresses When you go, again the outer guide rail 17
_b , so that the suspension vehicle 1 is prevented from tilting.

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 H ₁ . In the connecting portion _18b , instead of the hanger rail H, a rolling contact plate 27 having a ball bearing 26 on its upper surface is suspended from above as shown in FIG. The ball bearing 26 forms a spherical hole 26 _a on the upper surface of the rolling contact plate 27, a ball 26 _b accommodating therein,
The ball 26 _b and one obtained by interposing a plurality of small-diameter ball 26 _c into the gap between the spherical bore 26 _a, is configured so that the ball 26 _b even when a heavy load to the ball 26 _b is rotated lightly ing.

The distance L between the rolling contact surface of the ball bearing 26 with respect to the auxiliary support member 25 and the upper surface 2 _a , 2 _b that is the traveling surface of the hanger rail H is determined by the hanger rail H of the wheels 9 _a , 9 _b , 9 _c. Is set to be slightly longer than the distance 1 between the contact surface of the auxiliary support member 25 and the rolling contact surface of the auxiliary bearing member 25 with the ball bearing 26. The difference between the distances L and l is, for example, 0 to 2 mm, preferably 0 to 0.5 mm, so that the auxiliary support member 25 can easily ride on the ball bearing 26 and the ball bearing 26 to the hanger rail H. It is desirable that there be almost no shock when transferring.

Further, a vertical guide piece 21 is formed at the center of the lower surface of the rolling contact plate 27 so as to extend by cutting out the lower portion of the web portion W of the hanger rail H. As shown in FIG. 6, the rolling contact plate 27 having such a vertical guide piece 21 has one (27 _a ) on the branch side hanger rail H _1.
, And the other (27 _b ) is connected to the straight-ahead side hanger rail H ₂ , respectively, which enables a special traveling state as described below.

That is, as shown in FIG. 4, the upper guide wheel (upper side) 1
2 _a and the auxiliary support member 25 is Tsukuruma 1 disposed on the right side in the figure, if that has traveled as indicated by an arrow 22 shown in Figure 6, at the connection portion of the connecting portion 18 _b and the hanger rail H, first The auxiliary support member 25 rides on the ball bearing 26 on the upper surface of the rolling contact plate 27. As described above, the distance L between the upper surfaces 2 _a and 2 _b of the hanger rail H and the upper surface of the ball bearing 26, and the distance between the lower surfaces of the wheels 9 _a , 9 _b and 9 _c and the rolling contact surface of the auxiliary support member 25. Since the difference from 1 is small and the inertia of the suspension vehicle 1 is applied, the auxiliary support member 25 easily rides on the ball bearing 26 of the rolling contact plate 27.

With such auxiliary support member 25 rides completely on the ball bearing 26, the upper guide wheel 12 _a is in contact rolling the vertical guide piece 21, thereby advancing direction of Tsukuruma 1 is deflected to the right, the arrow 22 _As indicated by _a , the suspension vehicle 1 advances toward the branch-side hanger rail H ₁ . When Tsukuruma 1 reaches through the branch portion to the connection portion between the branch side clothes rail H ₁ and the connecting portion 18 _b, off the ball bearing 26 on the auxiliary support member 25 is rolling contact plate 27, the wheels The suspension vehicle 1 is made to travel again along the hanger rail H ₁ by the sliding contact of the 9 _a , 9 _b , 9 _c with the upper surfaces 2 _a , 2 _b , which are the travel surfaces of the branch-side hanger rail H ₁ . At this time, as the vertical member 7 _a of the left Tsukuruma 1 does not interfere with the straight rail of the connecting portion 18 _b, the straight rail of the connecting portion 18 _b notch 23 _a is formed. Further, the guide rail 17 _b is provided on the inner side than the vertical guide piece 21 of the connecting portion 18 _b, the lower guide wheels 15 by the contact rolling on the guide rail 17 _b, to prevent the inclination of Tsukuruma 1 You can also

On the contrary, even when the suspension vehicle 1 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 stage side and the auxiliary support member 25 work together. A smooth bending running state can be obtained.

Then, through the connecting portion 18 _b from the straight hanger rail H, a straight hanger rail H ₂ is Tsukuruma 1 will be described go possessed. In this case, used upper guide wheel 12 _a and the auxiliary support member 25 of the upper side is changed 180 degrees the direction of Tsukuruma 1 to be placed on the left side. Thus, the upper guide wheel 12 _b of the lower side is disposed on the right side of the web portion W. Such Tsukuruma is, if that has traveled to the connecting portion of the connecting portion 18 _b and the hanger rail H, upper guide wheels 12 _a, 12 _b upper guide wheel 1 in the lower side by the arrangement of the
Since _2b passes below the end 20 of the vertical guide piece 21, both upper guide wheels _12a and _12b are
Without rolling contact with the vertical guide piece 21, rides on ball bearings 26 of the auxiliary support member 25 is rolling contact plate 27 _b. In this way, the auxiliary support member 25 causes the wheels 9 _a , 9
_{While the b} and 9 _c are kept in the lifted state, the suspension vehicle keeps the straight traveling state, and the straight traveling hanger rail H ₂ from the connecting portion 18 _b.
Transfer to. At this time, the vertical members 7 _a direction of travel right to the branching rail connecting portion 18 _b so as not to interfere with the branching rail connecting portion 18 _b is formed with a 23 _b notch.

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.
