DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger for collectively supporting a plurality of (three or more) insulated trolley wires arranged in parallel to form a plurality of continuously installed insulated trolley wires.

[0002]

2. Description of the Related Art A multi-insulation trolley wire used for power supply and control of a self-propelled transport device has a total of six wires including three wires for power supply, one wire for ground, and two wires for control. Therefore, 6P hangers that collectively support six insulated trolley wires have been used as standard products. Such a standard 6P hanger has been manufactured as an integral product using an injection mold. However, when the control signal is transmitted wirelessly, it becomes a four-wire system.
In some cases, hangers for P and 5P are also required. In such a case, hangers for 4P and 6P are manufactured by a unique injection mold.

FIG. 10 shows an example of a conventional 4P hanger. The hanger is made of one piece and is formed by injection molding with a predetermined die. Four sets are arranged in parallel. In such a hanger, the rear surface of the board part 1 is applied to the side surface of the rail for traveling of the self-propelled carrier, and through the through holes 3 and 3 formed in the diagonal part of the board part 1, a set screw is passed. Are fixed to the rails by screwing them into the rails, and the insulating trolley wires are pressed into the respective clamp pieces 2 so that the insulating trolley wires to be laid in series are grasped collectively.

[0004]

In the conventional hanger for multiple laying trolley wires, which is a monolithic unit that supports a large number of trolley wires in a lump, the number of trolley wires to be laid is limited. Each time it changes, for example, 4P
Since different sized hangers were prepared by preparing different molds for each of 5P, 6P, and 6P, and injection-molding them one by one, the production cost could not be avoided. There were many types and inventory management was not easy. On the other hand, there has been an example in which hangers for a single wire, which individually support one insulating trolley wire, are arranged by the number of laying the insulating trolley wires, and these are collectively fixed by a channel material of a pressed steel plate. In such a combination type hanger, the hanger body itself can be diverted to a hanger for a single wire, and there is no need to newly create a mold for a hanger dedicated to multiple laying, but a plurality of hangers are fixed collectively. The channel material cuts the steel sheet to the required size according to the number of insulating trolley wires laid, and then presses the specified steel sheet into a press machine and bends it. It required a dedicated machine and did not contribute to reducing manufacturing costs. In addition, it is necessary to screw each of the many hangers, and the assembling work is not easy.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention uses a plurality of hanger pieces, each of which may have the same shape, and a support base capable of commonly supporting them. The support base can be cut and selected to the required length according to the number of installed trolley wires, that is, the number of hanger pieces, as an extruded mold material, so that it can be used.
Therefore, regardless of the number of insulated trolley wires installed, the manufacturing dies etc. are standardized to reduce the manufacturing cost and also provide a hanger that can be assembled flexibly in response to the increase or decrease in the number of insulated trolley wires installed. It is.

That is, the support base is made of a cut extruded plastic material and has, on one side surface, continuous irregularities which are cured in the extrusion direction and through holes formed from the surface having the irregularities. One of the plurality of hanger pieces is made of a plastic molded article having the same shape, and has a strip-shaped substrate portion as a base, and has, on the back side thereof, projections and depressions penetrating in the short width direction, and the front side of the substrate portion. Has a clamp piece integrally projecting in one half and a through hole drilled in the other half, and a large number of hanger pieces join their own unevenness to the unevenness of the support base. one in the extrusion direction of the support base while

And set the through hole in the middle hanger piece and the corresponding through hole in the support base for inserting the set screw.
The support base with the middle hanger piece on the rail or
Is attached to other buildings.
You . The unevenness of the support base and the unevenness of the hanger piece consist of a series of dovetail-shaped side grooves extending toward the inner bottom surface and a ridge with an enlarged tip adjacent thereto, and the unevenness of the hanger piece is fitted to the unevenness. What is necessary is just to be able to slide along the extrusion direction of the support base in this state.

[0007]

1 to 7 show a preferred embodiment of a multi-insulation trolley wire hanger according to the present invention. FIG. 1 shows a state in which the hanger is installed, and FIG. Shown with trolley wire attached, FIG.
Shows a hanger piece alone, FIG. 4 shows a long intermediate product of the support base, FIG. 5 shows a finished product after cutting the support base, and FIG. 6 shows a hanger in the middle of assembling, FIG. 7 shows the hanger in an assembled state.

[0008] The hanger H of this embodiment comprises a support base 10
And a hanger piece 20 in combination. Thus, the support base 10 is first of all shown in FIG.
Is provided as a long intermediate product 11. this is,
It is made of an extruded material from a plastic extruder, is formed in a substantially strip shape, and has irregularities 12 continuous on one of the plate surfaces along the extrusion direction. This unevenness 12
Is formed by a series of a dovetail groove 13 having an enlarged bottom and a ridge 14 having an enlarged tip adjacent thereto. The intermediate product 11 of the extruded material having such irregularities 12 can be manufactured to be long by extruding it into a strip shape and then continuously rolling it with a roll.

Such a long intermediate product 11 can be traversed in a predetermined length, that is, in the parallel direction of the multiply-insulated trolley wires T at an appropriate time, for example, when the number of multiply-insulated trolley wires T (see FIG. 2) is determined. Cut into lengths for use. Then, the cut support base is finished in a shape as indicated by reference numeral 10 in FIG. That is, the support base 10 cut into a predetermined length (in this embodiment, a length corresponding to the installation of three insulated trolley wires) is provided with a through-hole pierced from the bottom surface of the side groove 13 with an uneven surface. A hole 15 is formed. The through holes 15 are provided in a staggered arrangement corresponding to the number of hanger pieces 20 to be used, which will be described later. (In the case of the present embodiment, three through holes are arranged in a zigzag pattern.) On the other hand, the hanger piece 20 is formed as a molded body of engineering plastic, and is formed on the base of the strip-shaped substrate portion 21. It has an unevenness 22 that penetrates in the short width direction, and a pair of clamp pieces 25 project integrally from one half of the front side of the substrate part, and the other half from the front side. The through hole 26 is formed so as to reach the unevenness on the back side. The projections and depressions 22 can be fitted into the projections and depressions 12 of the support base, and therefore, like the projections and depressions 12, have a dovetail-shaped side groove 23 and a jetty 24 with an enlarged tip. Clamp piece 25
Have an undulation such that the facing surface can be fitted and locked to the grooved side surface of the insulating cover of the insulating trolley wire T (see FIG. 2). A groove with a radius is provided at a base inside the clamp piece 25 so that a spring action of the clamp piece 25 can be obtained. The clamp piece 25 has an inverted C-shape so that the opposing distance becomes narrower toward the tip end, thereby improving the elastic holding force when the insulating trolley wire T is fitted. Further, the through hole 26 is opened on the surface of the uneven ridge 24 on the back side, and a counterbore 27 having a larger hole diameter is formed on the front side so that the head of a set screw can be inserted.

According to the present embodiment, the hanger pieces 20 shaped as described above need only be of one type, so that they can be mass-produced in one mold and supplied in a required number. In this embodiment, three hanger pieces 20,
20, 20 are supplied and assembled. 6 and 7 show the assembling procedure. First, as shown in FIG. 6, three hanger pieces 20, 20, 20 are juxtaposed in the same direction and each of the projections and depressions 22 is used as a support base. The support base 10 is slid in the pushing direction of the support base 10 so as to fit into the unevenness 12 one after another, and is continuously provided in the pushing direction of the support base. At this time, the clamp pieces 25 of adjacent hanger pieces are arranged in a staggered arrangement. Unevenness 22 and unevenness 12
Are the gutters and jetties of each other, ie 13 and 24, 23 and 14
Are fitted to each other, so that each hanger piece 20 is hooked on the support base 10.

In the above state, each hanger piece 20
May remain slidable in the direction in which the support base 10 is pushed out, and thus may be detached. Therefore, as shown in FIG. 7, the through holes 26 of the hanger pieces are aligned with the through holes 15 of the support base in a state where the hanger pieces 20 are arranged in order on the support base 10, and the hanger pieces on both sides are arranged. The spring pins 30 are pierced through the skewers in the through holes of the support base and the through holes of the support base corresponding thereto, so that the hanger pieces on both sides are prevented from coming off. The middle hanger piece is inevitably stuck between the two hanger pieces. The through hole of the intermediate hanger piece and the through hole of the support base corresponding thereto are free and set for inserting a set screw 40 described later.

As shown in FIG. 1, the hanger H of this embodiment, which has been assembled as described above, has the back surface of the support base 10 applied to the side surface of the rail R for self-propelled transport equipment, and the set screw By inserting 40 from the front surface of the middle hanger piece into its own through hole and the through hole of the support base corresponding thereto, and screwing it into the rail R, the installation of the hanger H on the rail R is completed. The head 41 of the set screw 40 is inserted into the counterbore 27 provided on the front side of the through hole so as not to hinder the support of the insulating trolley wire. Since the rail R is generally made of aluminum, the set screw 40 uses a tapping screw in this embodiment. As the set screw, a screw other than the self-tapping screw may be used in consideration of the supporting equipment, that is, the material of the rail.

The hanger H installed as described above supports the insulated trolley wire of the last date mark. FIG. 2 shows a state in which the insulating trolley wire T is attached to the hanger H in which the installation state is omitted. That is, when the three insulated trolley wires T, T, T are pushed into the clamp pieces 25 of the three hanger pieces 20, 20, 20, which are arranged in parallel, the clamp pieces 25 are hooked on the insulating cover Tc to achieve elastic clamping. In this way, support for the insulating trolley wire on each hanger piece is obtained. The clamp piece 25 holding the insulated trolley wire T was originally in an inverted C-shape so that the opposing distance is reduced on the distal end side, but is now in a state of being spread in parallel. Note that the hanger piece clamp pieces are staggered.
To push the insulation trolley into the clamp piece
Sometimes it is necessary to eliminate the pressing of adjacent clamp pieces
Has the effect. That is, press the insulating trolley against the clamp piece.
When inserting, the inside of the clamp piece is on the groove side of the insulating cover.
Because it has a raised surface that can match and lock the surface
In addition, the shape of the inverted U-shape was expanded in parallel
And the shape of a triangle is instantaneous, but the clamp piece is staggered.
Since they are arranged, the pressing of the clamp pieces between the adjacent hanger pieces 20 is eliminated.

FIGS. 8 and 9 show another example of a hanger for multiple insulated trolley wires according to the present invention. FIG. 8 shows a hanger alone in an assembled state, and FIG. 9 shows only a support base. Indicated.

The hanger H 'of this embodiment is for 6P as is apparent from FIG.
These are arranged in a staggered arrangement for each individual. The same hanger piece as that of the above-described embodiment is used as the hanger piece 20, but the support base 10 'is cut into lengths corresponding to the parallel addition length of six hanger pieces. As shown in FIG. 9, the through holes 15 are formed by staggering six holes.

In the hanger of this embodiment, the spring pins 30 are arranged to penetrate the skewers through the through holes of the hanger pieces on both sides, and the through holes of the four intermediate hanger pieces are made free. One or more through holes may be set for inserting the set screw. In the drawing, the through holes of the two outer hanger pieces are used for inserting setscrews, so that four through holes 15 are formed in the support piece 10 '. The details of the other parts, the installation procedure, and the like are the same as in the above-described embodiment, and a description thereof will be omitted.

[0017]

According to the hanger for a multiple laying insulated trolley wire of the present invention as described above, a plurality of hanger pieces each having the same shape and a support base capable of commonly supporting them are used. The supporting base can be cut and selected to the required length in accordance with the number of insulating trolley wires laid, that is, the number of hanger pieces, as an extruded die, so that the manufacturing mold can be used regardless of the number of insulating trolley wires laid. Thus, the desired object of providing a hanger that can be assembled flexibly in response to an increase or decrease in the number of insulated trolley wires, by reducing the manufacturing cost by standardizing the above, is achieved.
