Abstract

PURPOSE:To improve positioning accuracy of a suspending member by not fixing at least one of both engaging members to a side plate of a door-shaped member and by making the interval between the inner side of the other of the engaging members and the inner side of a side plate of the door-shaped member opposing it a little larger than the width between both the right and left side edges on the upper side of a rail. CONSTITUTION:A gap is formed between one of right and left side edges on the upper side of a rail 1 and one of side plates of a door-shaped member 3 adjoining it. Next, one engaging member 12a which has been removed is engaged with the other of the right and left side edges on the upper side of the rail at the position far from the door-shaped member using a groove 13a and inserted into one side plate of the door-shaped member by sliding this engaging member along the rail. In this state, both the side plates of the door- shaped member is fastened in the direction close to each other by bolts and nuts so that bolts 14a and 14b penetrate both the engaging members 12a and the door-shaped member is fixed at a predetermined position in the rail length direction, that is, the position where it can be connected to a rail suspending member 2 on the ceiling side.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hanging device for hanging a trolley conveyor rail from a ceiling side.

(Prior art and its problems) Conventionally, when suspending a trolley conveyor rail, a bracket was welded to the upper surface of the rail, and this bracket was connected to a rail hanging member on the ceiling side.

Therefore, since the hanging position in the rail length direction is determined by the position of the bracket, it is necessary to arrange the rail hanging member with high precision in accordance with the position of the bracket in the rail length direction. Also, since the bracket must be welded directly to the long rail,
The disadvantage was that welding work was time-consuming.

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
A pair of left and right fitting members each having grooves that fit into the upper left and right side edges of the trolley conveyor rail are arranged on the inside of both side plates of the portal member connected to the lower end of the rail hanging member. A hanging device in which both side plates of the gate-shaped member are fastened toward each other with bolts and nuts in a state where the bolt passes through the mating member, and at least one of the two mating members includes: It is not fixed to the side plate of the portal member, and the distance between the inner surface of the other fitting member and the inner surface of one side plate of the gate member opposing this is determined between the upper left and right edges of the rail. This is a trolley conveyor rail suspension device whose width is slightly larger than the width of the trolley conveyor.

(Operation of the Invention) When attaching the gate-shaped member to the rail, one of the pair of fitting members that is not fixed to the side plate of the gate-shaped member is removed, and then the other fitting member is removed. Fitting the gate-shaped member to the rail so that the upper left and right side edges of the rail fit between the inner surface of the member and the inner surface of one side plate of the gate-shaped member opposing the member, and , by laterally shifting the portal member to fit one of the upper left and right side edges of the rail into the groove of the other fitting member. As a result, a gap is created between the other of the upper right and left edges of the rail and one side plate of the gate-shaped member adjacent thereto, so that the one fitting member that is to be removed is separated from the gate-shaped member. rank i
The fitting member is fitted to the other of the upper left and right side edges of the rail using the groove, and the fitting member is slid along the rail to enter the inside of one side plate of the portal member. In such a state, both side plates of the gate-shaped member are fastened in the approaching direction with bolts and nuts so that the bolts pass through both fitting members, and the gate-shaped member is moved to a predetermined position in the rail length direction, that is, on the ceiling side of the rail. It can be fixed at a position where it can be connected to a hanging member.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In Figures 1 and 2, 1 is a trolley conveyor rail, 2 is a rail hanging member hanging from the ceiling, and 3 is a trolley conveyor rail.
is a gate-shaped member connected to the lower end of the rail hanging member 2. This portal member 3 and the rail hanging member 2
means that the receiver fixed by welding to the lower end side of the rail hanging member 2 is connected to the seat plate 4, the mounting Fi5 fixed vertically to the upper surface of the portal member 3 by welding, and the bolt that connects both. 6 and a nut 7. The seat plate 4 and the mounting plate 5 of the receiver are attached in such a direction that their plate surfaces are perpendicular to the length direction of the rail 1. 4a and 5a are textured so that they fit into each other and prevent relative sliding in the vertical direction.

Further, the bolt hole 8 of one of the mounting plates 5 is formed into a long hole in the vertical direction, and when the nut 7 is loosened, the retainer is opened with the mating surfaces 4a and 5a of the seat plate 4 and the mounting plate 5 disengaged. , mounting plate 5
The mounting height of the portal member 3 to the rail hanging member 2 can be adjusted by tightening the nut 7 after the support is raised and lowered relative to the seat plate 4 within the range of the bolt hole 8.

The connection structure of the gate-shaped member 3 to the rail hanging member 2 is not limited to the above structure.For example, as shown in FIG. At the same time, the thickness of the mountings vi and IO fixed perpendicularly to the upper surface of the gate-shaped member 3 is made larger toward the upper end, so that the support is made to fit between the seat plate 9 and the mounting plate 10. By inclining the contact surfaces 9a and 10a as shown,
When the seat plate 9 and the mounting plate 10 are fastened together using the bolts 6 and naphuts 7, the receiver may be configured so that relative slippage in the vertical direction between the two can be prevented by the inclination of the elbow contact surfaces 9a and 10a. I can do it.

Fitting members 12a, 12b are arranged inside the left and right side plates 11a, llb of the gate-shaped member 3. Grooves 13a and 13b that fit into the upper left and right side edges 1a and fb of the rail 1 are formed on the inside of these fitting members 12a and 12b over the entire length, and only one fitting member 12a is attached to the gate-shaped member 3. It is fixed to one side plate ILa by welding.

Further, bolt holes 16 are provided in both side plates 11a and llb of the gate-shaped member 3 and both fitting members 12a and 12b for passing two bolts 14a14b in the left and right lateral directions. 15a and 15b are nuts.

The distance D1 between the inner surface of the fitting member 12a and the inner surface of the side plate 11b of the portal member 3 opposing thereto is slightly larger than the distance D2 between the upper left and right edges 1a and lb of the rail 1. It has become.

When connecting the rail 1 to the rail hanging member 2, the third
As shown in the figure, the portal member 3 with one fitting member 12b removed is fitted onto the rail 1 from above. At this time, due to the relationship between the distances DI and D2, the upper left and right side edges 1a and lb of the rail 1 fit relatively between the fitting member 12a and the side plate 11b of the portal member 3 facing thereto. In this state, the portal member 3 is laterally shifted relative to the rail 1, and the groove 13a of the fitting member 12a is aligned with one side edge 1 of the rail 1.
Fit into a. As a result, the other side edge 1b of the rail 1
Since a gap is created between the side plate 11b of the gate-shaped member 3,
The fitting member 12b fitted into the side edge 1b of the rail 1 using the groove 13b at a position away from the gate-shaped member 3 is slid toward the gate-shaped member 3, and the fitting member 12b is It can be inserted between the side edge 1b of the rail 1 and the side plate 11b of the portal member 3. When all the bolt holes 16 are aligned, the bolts 14a and 14b are passed through the side plates 11a and llb of the portal member 3 and both fitting members 12a and 12b, and the nut 15a is inserted.

15b. Then, the portal member 3 is attached to the rail 1 using the grooves L3a and 13b of each fitting member 12a and 12b.
The mounting plate 5 is slid in the length direction of the rail suspension member 2, and the receiver of the rail hanging member 2 is brought into contact with the seat plate 4. After adjusting the height, the mounting plate 5 is fastened with bolts 6 and nuts 7. After this, Natsu 1
