Furthermore, since it is symmetrical with respect to the center line, it can be attached to the machine frame without considering its orientation, and it can also be easily bent to accommodate curved path sections.

Example An embodiment of the present invention will be described below based on the drawings.

As shown in Fig. 1, the rail 1 has a rectangular cross section, with a flat wheel holder formed on the entire upper surface 2, and a downwardly open lower dovetail groove 3 formed over the entire length at the lower part. are doing. Inside the rail 1, an upper through passage 4 and a lower through passage 5 are formed with a rectangular cross section. Furthermore, at multiple locations (four locations) in the vertical direction on both sides of the rail 1, there are side dovetail grooves 6A, 6B, 7A, 7B, 8A, 8B that are open to the sides.
, 9A, 9B are formed over the entire length, and flat guide roller guide surfaces IQA, IOB are formed between the uppermost side dovetail grooves 6A, 6B and the second side side dovetail grooves 7A, 7B. are doing. Here, side dovetail grooves 6A, 6B, 7A, 7B, 8A
, 8B.

9A, 9B and guide roller guide surface 10A, IOB are:
It is formed symmetrically with respect to the center line H. The rail 1 is a pultruded aluminum part, with side dovetails 6A, 6B, 7A, 7B, 8A, 8B, 9A, 9
In B, the upper part is formed vertically asymmetrically so that the recess is large.

As shown in FIGS. 1 to 5, the rails 1 are mounted as a pair of left and right rails on the machine frame at predetermined intervals. That is, a tap plate 16 is inserted into the lower dovetail groove 3, and the rail 1 is fixed by fitting and tightening the bolt 17 passed through the machine frame from below into the tap plate 16. Normally, the rail 1 is attached to the machine frame 1 at a joint in the length direction of the rail 1.

That is, the joint portion has an inclined cut shape in plan view, and the tap plate 16 is disposed between both ends. Then, the upper guide member inserted between the upper through passages 4 is fixed to one end of the rail in the length direction with a bolt fixing tool 19, and the other rail end is left free, and the upper guide member is inserted between the upper through passages 4. The lower guide member inserted over the length of 5 is fixed to the other rail end with the bolt fixing tool (2), and the - rail end is left free. At this time, the bolt fixture 19 is located in the side dovetail groove 6A, and the bolt fixture 4 is located in the side dovetail groove 7B.

A connecting member 5 is attached between opposing sides of both rails 1. This connecting member 5 consists of an outer plate I that can be freely attached to the inner side of the rail 1, a bottom plate I that connects the lower ends of these outer plates, and a plurality of (2
These inner plates are placed higher than the outer plates, and the receiver connects the plate parts 4 inwardly from the upper end. In these receivers, a cover plate (material) is placed between the plate parts 9, and both are integrated with a fixture or the like. Here, the upper surface of the cover plate (9) has the wheel holder of the rail 1 almost the same as the surface 2, and both side edges are arranged so that the rail 1 is not hindered in running the self-propelled cart (described later).
is close enough to As a result, a duct space 31 is formed by the bottom plate I, both inner side plate passages, and the cover plate portion, and a duct case wing is disposed within this duct space 31. The feathers represent signal lines, and the winnows represent power lines. Rail 1 of the outer plate part
For example, as shown in FIG. 4, a plate nut is inserted into the side dovetail grooves 8At8B, 9A, and 9B on the inside and below the guide roller guide surface 10A and IOB, and then a plate nut is inserted into the outer plate part. This can be done by inserting a bolt through the inside and tightening it by aligning it with a plate nut. Note that although the fixation is shown in two stages in the vertical direction, this may be in negative stages. In addition, as shown in FIG. 1, the lowermost side dovetail groove 9A,
For example, feeder wires W can be placed inside the outside 9A of 9B, and bolts and wires can be installed inside the inside 9B.
The detected closure is established via a fixing device such as a nut. A power supply device is disposed on the inner surface of the outer plate portion on one side of the connecting member portion.

Reference numeral 41 denotes a self-propelled trolley, which has a pair of front and rear driving wheel centers arranged on the lower side of its main body C, and a pair of front and rear idling wheels arranged on the other side. By placing the wheel supports of the rail 1 on the surface 2, the rail 1 can run freely on a fixed route.

Both driving wheel centers each have an axle 47 in a case with an open bottom.
The case cap is fixed to the lower end of the vertical rotating shaft supported on the side of the main body c. Therefore, the driving wheels C can freely turn around the vertical axis 6. A driving device (such as a motor) 50 is attached to each of the case chrysanthemums, and these driving devices are linked to the corresponding axle 47. Further, a plurality of guide rollers 52A and 52B facing the guide roller guide surface 10A and IOB of the rail 1 are attached to the case boiling bracket 51. The two-way wheel material is attached to the bracket between the axles, and the bracket product is attached to the slide plate group supported on the center side of the main body via the longitudinal axle. That is, a base plate a is fixed to the main body C, and a group of oval through holes elongated in the width direction of the truck are formed in the base plate a. On the lower surface of the base plate U, long guide rails are attached in the width direction of the bogie at the front and rear between the through holes, and the slide plate group is supported and guided by both guide rail groups via sliding bodies ω, and slides in the width direction of the bogie. Become free. The guide rail I and the sliding body ω constitute a wide LM guide. Note that a plurality of load balls are arranged between the guide rail group and the sliding body ω, if necessary. A bearing 61 disposed on the slide plate 5 is located between the vertical shafts erected from the center of the upper surface of the bracket group.
Insert the bearing, and then clamp the bearing between the retaining washer attached to the top end. Note that the bearing 61 is fixed to the slide plate 5 side by a bearing presser.

As a result, the free-rotating wheel shed can freely rotate around the six vertical axes relative to the slide plate group. The lower end of the bracket group includes a guide roller guide surface 10A of the rail 1,
A plurality of guide rollers 65A, a facing the IOH
513 is attached. A current collector hammer corresponding to the power supply device disconnection is provided on the main body side.

Next, the traveling work in the above embodiment will be explained.

The self-propelled truck d, which is placed on the surface 2 of the wheel holder of the rail 1 via each wheel center 44, is forced to rotate the drive wheel center by the operation of the drive unit, so that the guide roller guide surface 10
A, guide rollers 52A, 52B, 6 facing IOB
The vehicle travels along a fixed route while being guided by 5A and 65B. At that time, since the two driving wheel centers are in contact with the wheel holder surface 2, the pressure of the two wheels acts, and this high wheel pressure is used to accelerate and decelerate, reducing the acceleration distance and deceleration distance. It can be shortened and easily and stably performed. When the self-propelled truck enters the curved route section as shown in Fig. 6, the circumferential drive wheels 6 rotate individually around the vertical axis via the case chrysanthemum and the rotating shaft, and also rotate both freely. The wheels rotate individually around the vertical axis through the bracket group and the vertical axis. That is, all the wheels 44 turn independently to follow the curve of the rail 1. Furthermore, in the curved path portion τ, guide rollers 65A, 6 guided by the rail 1
By applying an outward lateral pushing force to the bracket 51 via 5B and by supporting and guiding the sliding body ω by the guide rail group, the unit with weak idle wheels automatically moves outward. Become. As a result, compared to the distance l between the left and right wheels in the straight route part n, the distance between the wheels in the curved route part 70 is longer L1, that is, l<L, and the rail width of the curved route part 70 is made the same as the rail width of the straight route part n. Even though it is the same, it is possible to drive smoothly and without strain. Furthermore, when traveling on the curve route section 70, when both drive wheel centers are within the curve route section π as shown by H in FIG. 6, these drive wheel centers are on the same inner rail 1 (same route Up)
, so there is no speed difference between the two drive wheels.

In addition, as shown by I in Fig. 6, when only one driving wheel center is in the curved path at the entrance or exit of the curved path, there is a small gap (less than 3%) between both driving wheels. ), but such a speed difference does not require speed control.

In order to form the curved path portion τ as described above, the rail 1 itself must be bent and formed.
Since the shape is symmetrical and easy to bend, it can be easily and accurately bent with a bender.

When the rail 1 is arranged in a machine frame, there is no need to select between the left side and the right side because the rail 1 is symmetrical as described above. When the guide rule 1 is arranged in a straight line, a stretchable joint can be formed by the upper and lower guide members 20 fixed in opposite directions;
It has a structure that allows it to be housed within the rail 1, making it suitable for aesthetics.

Side dovetail grooves 6A and 6B formed on both sides of the rail l.

Various parts can be installed and arranged using 7A, 7B, sA, sB, 9A, and 9B. At this time, each dovetail groove is formed so that the upper part has a large recess, so that a plate nut or the like can be inserted from anywhere, as shown by the imaginary line A in FIG. 1, for example.

The connecting member portion between the rails 1 can be easily arranged using the side dovetail grooves, and the space formed by the connecting member 5 and the cover plate blade is provided with a signal line feather or a power line support. Wiring and arranging various equipment can be done. The wiring and arrangement may be done using a duct case cover, and in this case, the cover plate also serves as the lid of the duct case skin.

In addition, by arranging the power supply equipment ship within the connecting member δ, it is safe because the power supply equipment ship cannot be easily disconnected from the outside, and the TEPCO equipment area can be seen from the side when the power supply equipment is turned off. By this action, the self-propelled cart d can be easily taken out from the fixed route by simply lifting it upward.

In the above embodiment, the idle wheel group is movable in the left-right direction, but it may be of a fixed type, that is, a type in which the vertical shafts are attached to the main body c side.

Effects of the Invention According to the present invention having the above configuration, by positioning the slidable nut body within the dovetail groove, various devices can be easily mounted using this nut body without drilling holes. be able to. Furthermore, by sliding the nut body, the mounting accuracy can be easily achieved, and the mounting position can be easily changed. Furthermore, the inside of the dovetail groove can be used for wiring, for example, feeder lines.

With these features, peripheral devices such as control equipment, power supply devices, and detection devices can be easily and orderly arranged. Furthermore, since the shape is symmetrical with respect to the center line, it can be easily mounted to the machine frame without considering the orientation, and bending work for curved route sections can be done on either the left or right side. It can be done easily.
