Description

Description: TECHNICAL FIELD The present invention relates to a suspension vehicle for moving walls (hereinafter referred to as suspension vehicle) system, and in particular, smooth suspension of the suspension vehicle at the orthogonal portion (intersection) of the hanger rail, which is the traveling track thereof. The present invention relates to a suspension vehicle system for a moving wall, which has a high degree of freedom in controlling the traveling direction and enables various traveling.

[Prior art]

FIGS. 9 (a) and 9 (b) show a traveling state of an example of a conventional suspension vehicle for a moving wall (state in which the suspension vehicle approaches a hanger rail intersection).

In the figure, reference numeral 1 is a suspension vehicle main body, which has a vertical moving wall suspension shaft 2 below the central portion thereof, and a shaft for suspending the moving wall below the vertical shaft 2. Two vertical wheels 3a, 3a are provided on each of the four front, rear, left and right sides. , 3b, 3b, 3c, 3
It has c, 3d, 3d rotatably. Numeral 4 is a hanger rail laid on the ceiling, which is orthogonal to the intersection shown in the figure.

However, in FIG. 9 (a), these hanger rails are shown in a state of being cut at the central horizontal plane, and the lower portion of the traveling plate 4a is displayed, but the actual product is shown in FIG. 9 (b). As shown in, the lower running plate 4a, 4a, the vertical side wall 4b following this, horizontal upper wall 4c connecting the side wall at the upper end, and the lower wall central portion of the upper wall 4c is continuous in the longitudinal direction. The vertical wheel 3a, 3b or 3c, 3d is in contact with the upper surface (traveling surface) of the traveling plate 4a so that the suspension vehicle main body 1 is formed. Run on the hanger rail with the moving wall suspended.

Reference numeral 5 denotes a groove formed on the upper surface of the traveling plate 4a and continuous in the rail axial direction on the arc of the cross section. For example, the vertical wheels 3a and 3b positioned at right angles to the traveling direction indicated by the arrow X contact and interfere with the upper surface of the traveling plate 4a. This is to prevent it.

On the upper surface of the suspension vehicle body 1, four guide rollers 6a, 6b, 6c, 6
d are arranged at regular intervals, and as shown in FIG. 9 (b), they roll on the left and right sides of the guide rail 4d with a minute gap, and the suspension vehicle main body 1 is guided by this guide rail 4d. To keep going straight.

Then, when the suspension vehicle main body 1 goes straight in the direction of the arrow X and approaches the intersection of FIG. 9 (a), the front wheel of the vertical wheels 3c, 3d parallel to the traveling direction is the hanger rail 4. It will pass over the break E (a groove for the suspension shaft 2 to pass through), and the suspension vehicle body 1 will be loaded by the load applied to the suspension shaft 2.
Will tilt. Then, when the hoisting vehicle advances as it is, the wheels 3a that have fallen off at the break E collide with the traveling plate and impact the hoisting vehicle and the moving wall.

Further, when the suspension vehicle further advances and reaches the center position of the intersection of the hanger rails as shown in FIG. 9 (a), the vertical wheels 3c, 3d, which have been rollingly contacted with the upper surface of the traveling plate 4a, move in the traveling direction. The vertical wheel 3a to 3d is fitted into the groove 5 in the right angle direction, so that all the vertical wheels 3a to 3d are fitted into the circular arc-shaped groove 5 in the vertical and horizontal directions, and the suspension vehicle main body 1 moves downward by the depth of the groove 5 to suspend the suspension vehicle. Progress is temporarily stopped.

Therefore, when a force is applied to the suspension vehicle main body 1 in any of the front, rear, left, and right directions at this central position, the suspension vehicle main body 1 begins to move in that direction, and the traveling direction can be changed to an arbitrary direction.

[Problems to be solved by the invention]

However, such a suspension vehicle has the freedom to change the traveling direction as described above and has extremely high practicality.
It has the advantage that the suspension force is strong because the load of the moving wall is received by a large number of vertical wheels during normal traveling, but as mentioned above, when the suspension vehicle approaches the intersection of the hanger rails, the suspension vehicle on the front side There is a problem that the main body of the suspension vehicle is cantilevered and tilted after passing through the cut of the hanger rail, and when the suspension vehicle advances in that state, the front wheel impacts the hanger rail and receives a shock.

Further, as described above, at the center of the intersection of the hanger rails, as a result of all the vertical wheels of the suspension vehicle being fitted into the groove 5, a new state from this insertion stopped state (state in which the suspension vehicle body is depressed by the depth of the groove 5) is newly added. When trying to start the suspension car,
The vertical wheel in the traveling direction must escape from the groove shown in FIG. 9 (b) and ride on the upper surface (traveling surface) of the traveling plate 4a.

The depth of the groove 5 is such that the vertical wheels (3a, 3b) perpendicular to the traveling direction of the suspension vehicle, which swing slightly to the left and right during traveling straight ahead, are
It is necessary to make a deep R surface so that it does not interfere with the upper surface of a, and the vertical load acting on one suspension vehicle is usually 100
Since the weight ranges from kg to several tons, the vertical wheel has a very large resistance to get over the groove 5 and escape.

In the case of a moving wall, in order to move it, it is not possible to directly push the suspension vehicle stored in the ceiling, but by moving the suspension wall hanging from the suspension vehicle, the suspension vehicle is moved via the suspension shaft. Therefore, if the resistance of the groove 5 is large as described above, it may be practically impossible to move the suspension vehicle from the hanger rail intersection.

[Object of the Invention]

Therefore, the object of the invention is to achieve a smooth running state in which the suspension vehicle can cross the break of the hanger rail without being impacted even at the center of the intersection of the hanger rail, and can be started with a small force. That is.

[Means for solving problems]

The main means adopted by the present invention in order to achieve the above-mentioned object is that the gist of the invention is that four sides of a substantially right-angled hexahedron suspension vehicle main body on which a moving wall suspension shaft is vertically attached downward are respectively provided. One or more vertical wheels are mounted at a height so as to be in contact with the same horizontal plane, and a small-diameter body portion that extends vertically from the upper surface of the suspension vehicle body is formed on the upper portion of the suspension vehicle body. A rectangular plate-shaped auxiliary support plate is fixed horizontally, and the four corners of the intersection of the hanger rail on which the vertical wheels are rotatably contacted with each other have the same height as that of the hanger rail at the four corners that allow the passage of the suspension shaft. The hanger in which auxiliary rails connected to the hanger rails are attached, and further, a plurality of ball bearings are respectively attached upward so as to be capable of rolling contact with the lower surface of the auxiliary support plate at the four corners of the intersection and on the building structure side. A rolling contact plate made of a member different from that of the above-mentioned auxiliary support plate, the both ends of the auxiliary support plate in the traveling direction of the suspension vehicle main body, the vertical wheels parallel to the traveling direction of the suspension vehicle main body at least in the traveling direction of the break. The suspension vehicle system for a moving wall according to a point extending to a position where the ball bearing is brought into contact with and separated from the ball bearing in a state corresponding to a portion deviated from the front and rear ends.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the accompanying drawings of FIGS. 1 to 8.

Here, FIG. 1 is a front view (a hanger rail is shown by a chain double-dashed line) showing a traveling state in the center of a straight part of a hanger rail of a suspension vehicle according to an embodiment of the present invention, and FIG. 2 is a front sectional view of the suspension vehicle. 3, FIG. 3 is a view taken along arrow AA in FIG. 1, FIG. 4 is a front sectional view showing a traveling state of a suspension vehicle at an intersection of hanger rails, and FIGS. 5 and 6 are views taken along arrow BB in FIG. Schematic configuration diagram and schematic configuration diagram of the same CC, FIG. 7 is the same D
-D is a schematic configuration diagram as viewed in the direction of the arrow, and FIG. 8 is a schematic plan view showing a traveling state of the suspension vehicle at the intersection of the hanger rails.

In FIGS. 1 to 3, 10 is a substantially right-angled hexahedron-shaped suspension vehicle main body, and four vertical wheels 12a, 12a, 12b, 12b, 12c, 12c are provided on each of four side surfaces 11a, 11b, 11c, 11d thereof. , 12d, 12d, and side surfaces 11a ', 11b', 11 recessed from this toward the center of the body.
One vertical wheel 12a ', 12b', 12c ', 12d' on c ', 11d'
Is rotatably provided.

The vertical wheels 12a to 12d and 12a 'to 12d are mounted symmetrically in the front-rear direction and the left-right direction at a height capable of rolling contact with the traveling plate 14a of the hanger rail 14 (FIG. 1), which is the same horizontal plane.

As shown in the drawing, a hanging shaft 18 for a moving wall is rotatably fitted and hung down on the vertical central axis of the hanging vehicle main body 10. A bolt portion (not shown) for suspending the moving wall is engraved at the lower end of the suspension shaft 18. A vertically extending small-diameter body portion 21 is integrally fixed to the upper surface of the suspension vehicle main body 10, and a rectangular plate-shaped auxiliary support plate 22 in a plan view is provided on an upper portion of the small-diameter body portion 21.
Are fixed together.

On the other hand, as shown in FIG. 4, the intersection of the hanger rails 14
The auxiliary rails 23a having the same height as the traveling surface 14b of the traveling plate 14a are provided at four corners as shown in FIG. The ball rolling bearings 24, 24, ... are attached upward, and the rolling contact plate 25 is attached to a top plate 39, which will be described later, corresponding to the auxiliary rail 23a.

As shown in FIG. 4, the ball bearing 24 has a plurality of balls 26 radially rotatably incorporated therein, and the upper surfaces of these balls 26 are exposed upward from the upper surface of the rolling contact plate 25.

The ball 26 is housed in a spherical hole 26a formed in the rolling contact plate 25, and is rotatably supported by a large number of small balls 26b housed in the gap between the ball 26 and the spherical hole 26a.

A distance L between the rolling contact surface of the ball bearing 24 with respect to the lower surface of the auxiliary support plate 22 and the traveling surface of the auxiliary rail 23a (FIG. 4).
Is a running surface 14 which is a contact surface with the rail of the vertical wheel 12.
It is set to be slightly longer than the distance 1 (FIG. 1) between b and the lower surface of the auxiliary support plate 22. The difference between the distances L and l is, for example, 0 to 2 mm, preferably about 0 to 0.5 mm, and the auxiliary support plate 22
It is desirable that the ball bearing 24 can be easily mounted on the ball bearing 24 and that there is almost no impact when the ball bearing 24 transfers to the traveling hanger rail 14.

Therefore, for example, in the state shown in FIG. 1, when the hoisting vehicle main body 10 travels straight along the hanger rails 14, the vertical wheels 12c, 12d, 12c ', 12d' parallel to the traveling direction are mounted on the traveling plate 14.
c, 14c rolling contact with the running surface 14b, and the suspension vehicle body via the suspension shaft 18.
The load applied to 10 will be supported by these 6 wheels, and the vertical wheels 12c, 12c, 12 perpendicular to the traveling direction will be supported.
All of b and 12b are on the groove 5 formed on the upper surface of the hanger rail and are separated from the traveling plate 14a. Therefore, the vertical wheels perpendicular to the running direction do not interfere with the hanger rails 14 and the running of the suspension vehicle main body 10 in the direction perpendicular to the paper surface of FIG. At this time, the guide rollers 47, 47 described later are connected to the guide portions 49, 49 of the hanger rail 14.
And the straightness of the suspension vehicle body 10 is maintained.

As shown in FIGS. 4 and 8, the hanger rails 14 are connected to each other in a cross shape with the top plate 39 attached to the structure behind the ceiling at the intersection as a center. That is, the intersection 23
Is a composite structure composed of separate members such as a top plate 39 and a plurality of rolling contact plates 25 that are directly attached to the building structure, and is a structure different from the hanger rail 14; Combined with this, it is possible to withstand a heavy load sufficiently, and it is possible to meet various specifications by exchanging only the intersection 23 as appropriate according to the application and scale.

A female screw 40 is formed vertically at the center of the top plate 39, and a ball holding cylinder 41 is screwed to the female screw 40. The ball holding cylinder 41 has a substantially cylindrical shape, and its lower end is formed with a small diameter so as to prevent the balls 42 housed therein from falling.

A compression spring 45 is contracted between the ball 42 and the cover plate 44 screwed to the female screw 43 formed on the upper end of the inner cylinder portion of the ball holding cylinder 41, and the ball 42 is always elastically biased downward. is doing.

A spherical groove 46 having the same diameter as the radius of the ball 42 is formed at the top of the suspension vehicle, that is, at the center of the upper surface of the auxiliary support plate 22.

A guide roller 47 is rotatably attached to each of the four corners of the upper surface of the auxiliary support plate 22, and a cutout groove 48 through which the guide roller 47 can pass is formed on the lower surface of the top plate 39. It is shaped like a well.

Next, as shown in FIG. 8, the suspension vehicle main body 10 goes straight in the direction indicated by the arrow X and crosses the hanger rails 14, 14 ,.
I will explain the operation when approaching. However, FIG. 8 shows a state where the suspension vehicle main body 10 comes to the center of the intersection 23. In this case, the frontmost vertical wheels 12a facing the traveling direction,
At the time when 12b is about to enter the cut E, the end 22a of the auxiliary support plate 22 rides on the ball bearing 24 of the rolling contact plate 25. As described above, the running surface 14b and the ball bearing 24
Since the difference between the distance L from the upper surface and the distance 1 between the lower surface of the vertical wheel 12 and the lower surface of the auxiliary support plate 22 is small and the inertia of the suspension vehicle main body 10 acts, the auxiliary support plate 22 rolls. It easily gets on the ball bearing 24 of the plate 25. As a result, there is no inconvenience that the vertical wheels 12a12b on the front side in the traveling direction derail at the break E, and the load of the moving wall applied to the suspension shaft 18 gradually transfers to the rolling contact plate 25 via the ball bearing 24. .

Further, as the suspension vehicle main body 10 advances in the direction of arrow X, the auxiliary support plate 22 eventually rides on the ball bearing 24 as shown in FIG. As a result, all the load of the moving wall applied to the suspension shaft 18 is supported by the ball bearing 24.

As the auxiliary support plate 22 moves over the ball bearing 24 as described above, the guide roller 47 moves along with the guide groove 48.
And the straightness of the suspension vehicle main body 10 is maintained.

In this way, when the suspension vehicle body 10 reaches the center of the intersection 23,
A positioning ball 42, which is always elastically pressed downward by a compression spring 45, is fitted into a positioning spherical groove 46 formed in the center of the upper surface of the auxiliary support plate 22 of the suspension vehicle,
The operator can know that the suspension vehicle main body 10 has come to the center of the intersection 23 by the hand feeling at this time. When the operator travels the suspended vehicle main body 10 in the direction of another hanger rail 14 by the sense of position by the positioning balls 42 as described above, the operator of the suspended vehicle main body moves in the direction without the guide groove 48.
By pushing 10, it is possible to avoid the inconvenience that the guide roller 47 hits the wall of the top plate 39 and the suspension vehicle or the suspension shaft 18 is damaged.

As described above, as shown in FIG.
When stopped at the center of the intersection 23, the traveling wheels 12 are all substantially lifted from the traveling surface 14b of the hanger rail, so that the load of the moving wall is substantially completely supported by the ball bearings 24. .

Incidentally, the ball bearing 24 is lightly rotated in a so-called ball form in which the small-diameter balls 26b are confined as described above, and the load of the moving wall is supported by the plurality of balls 26, so that the load per ball 26 becomes small, There is no inconvenience of early wear.

In this way, when the suspension vehicle main body is stopped at the center of the 10th intersection 23, the suspension vehicle for the moving wall is further pushed in the direction of the arrow X or in the opposite direction, or in any of the four directions perpendicular to the arrow X. It can be made to proceed.

For example, when further advancing in the direction indicated by arrow X,
The end 22a of the auxiliary support plate 22 will be disengaged from the ball bearing 24, but prior to this, the front vertical wheels 12a, 1b.
Since b moves to the running surface 14b of the hanger rail 14, a large impact is not applied to the moving wall and the hanging vehicle for the moving wall.
When the moving wall suspension vehicle is restarted from the center of the intersection 23 as described above, the auxiliary support plate 22 only rolls on the ball bearings 24, so that the auxiliary support plate 22 can be restarted very lightly. This point is far superior to the conventional device shown in FIG.

As described above, the front vertical wheels 12a, 12 are connected to the front running surface 14b.
Then, the auxiliary support plate 22 travels on the ball bearing 24 and eventually falls off, but before that, the rear vertical wheels 12a ″ and 12b ″ transfer to the front running surface 14b of the hanger rail. Then 6 vertical wheels 12a, 12b, 12a ', 12
All of b ', 12a "and 12b" start rolling on the running surface 14b of the hanger rail, and the load of the moving wall is supported by these six vertical wheels.

〔The invention's effect〕

As described above, according to the present invention, one or more vertical wheels are respectively attached to the four side surfaces of the substantially right-angled hexahedron suspension vehicle main body to which the moving wall suspension shaft is vertically attached downward, at the heights in contact with the same horizontal plane. Along with the upper portion of the suspension vehicle body, a small-diameter body portion that extends vertically from the upper surface of the suspension vehicle body is formed, and a square plate-shaped auxiliary support plate is horizontally fixed to the upper portion of the small-diameter body portion in plan view. Auxiliary rails connected to the hanger rail at the same height as the hanger rail are attached to the four corners of the intersection of the hanger rail where the vertical wheels roll and which allow passage of the suspension shaft. At the four corners of the part, provided on the building structure side are rolling contact plates which are separate members from the above-mentioned hanger rails and each of which has a plurality of ball bearings mounted upward so as to be capable of rolling contact with the lower surface of the auxiliary support plate. auxiliary With respect to the ball bearing in a state where the vertical wheels parallel to the traveling direction of the suspension vehicle main body of the holding plate correspond to at least the part where the vertical wheels parallel to the traveling direction of the suspension vehicle main body deviate from the front and rear ends in the traveling direction of the break. Because it is a suspension vehicle system for moving walls that is extended to the position where it touches and separates, the vertical wheels at the intersection of the hanger rails are extremely smooth without falling into the cuts (cutouts) of the hanger rails. In addition to being able to maintain the running state, it is possible to freely change the running direction in any of the four orthogonal directions, and even if it is a heavy load moving wall, the transportation layout is free. It is possible to improve the degree at once.
