Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a suspension device for suspending a trolley conveyor rail from the ceiling side.

(Prior Art and Problems Thereof) When suspending a rail for a trolley conveyor, conventionally, a bracket was welded to the upper surface of the rail and the bracket was connected to a rail suspension member on the ceiling side. Therefore, since the suspending position in the rail length direction is determined by the position of the bracket, the rail suspending member must be accurately arranged according to the position of the bracket in the rail length direction. Further, since the bracket has to be directly welded to the long rail, there is a drawback that the welding work is troublesome.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
Grooves that are fitted to the upper left and right side edges of the rail for the trolley conveyor are cut on the lower ends of both side plates of the gate-shaped member connected to the lower end of the rail-suspended member over the entire length of the gate-shaped member. The present invention proposes a trolley conveyor rail suspension device in which both side plates of the gate-shaped member are fastened to each other by bolts and nuts in a state in which both upper and right edges of the trolley conveyor rail are fitted in the grooves in the approaching direction. .

(Embodiment) An embodiment of the present invention will be described below with reference to the attached exemplary drawings.

In FIGS. 1 and 2, 1 is a rail for a trolley conveyor using I-shaped steel, 2 is a rail hanging member hanging from the ceiling side, and 3 is a gate connected to the lower end of the rail hanging member 2. It is a shaped member. The gate-shaped member 3 and the rail suspension member 2 are connected to each other by a mounting plate 4 which is vertically fixed to the upper surface of the gate-shaped member 3 by welding, and a bolt and nut that connects the two. Reference numeral 5 denotes a suspending reinforcing member whose lower end is connected to the mounting plate 4 by a bolt nut. The mounting plate 4 and the rail suspension member 2 are
If necessary, the connection position can be adjusted vertically or vertically or horizontally.

The gate-shaped member 3 is formed by bending a strip-shaped iron plate having an appropriate thickness into a gate shape, and then forming rail-fitting grooves 7a, 7b at the inner lower ends of both side plates 6a, 6b as shown in FIG. It is formed by cutting the entire length of the member 3 and further forming bolt holes 8 at two positions in the lengthwise direction of both side plates 6a, 6b. As shown in FIG. 3, the rail fitting grooves 7a, 7b are formed in a vertical saw-tooth shape whose depth becomes shallower toward the lower edges of the side plates 6a, 6b. The both side edges 9 of the left and right overhanging plate portions 1a, 1b of the trolley conveyor rail 1 are fitted in the rail fitting grooves 7a, 7b.
Both side edges 9 are not rectangular in vertical cross section but are chamfered in an arc shape on the lower side, so that the gate-shaped member 3 is attached to the trolley conveyor rail 1 as shown by phantom lines in FIG. For example, one rail fitting groove 7b is fitted to the side edge 9 of one of the overhanging plate portions 1b, and from this state, the other rail fitting groove is attached to the side edge 9 of the other overhanging plate portion 1a. By forcibly rotating the gate-shaped member 3 in the direction of the arrow 10 with the fitting portion between the side edge 9 of the protruding plate portion 1b and the rail fitting groove 7b as a fulcrum so as to fit the groove 7a, The rail fitting grooves 7a and 7b can be fitted to both side edges 9 of the left and right projecting plate portions 1a and 1b on the upper side of the trolley conveyor rail 1. In other words, the space between the left and right side plates 6a, 6b of the gate member 3 is determined so that such a fitting operation can be performed.

As described above, the gate-shaped member 3 is connected to the trolley conveyor rail 1
, The two side plates 6a, 6b of the gate-shaped member 3 are immediately above each other on the trolley conveyor rail 1 by the two bolts 11 and nuts 12 which penetrate the bolt holes 8. The gate-shaped member 3 is fixed to the trolley conveyor rail 1 by fastening so that they approach each other. After this, the mounting plate 4
And the rail suspension member 2 are connected.

When the load applied to the trolley conveyor rail 1 is large, the outer lower end portions of the left and right side plates 6a and 6b of the gate-shaped member 3 (that is, the rail fitting groove) are shown in FIG. 4 and FIG. Outside the positions where 7a, 7b are cut, the reinforcing plates 13a, 13b having a width substantially the same as the width of the both side plates 6a, 6b are applied, and the reinforcing plates 13a, 13b are attached to the two bolts 11 and nuts. With 12, both side plates 6a, 6b can be fastened together, and the strength reduction at the position of the rail fitting grooves 7a, 7b can be compensated by the reinforcing plates 13a, 13b. Of course, the reinforcing plates 13a and 13b may be fixed to the outside of the side plates 6a and 6b by welding in advance.

(Operation and Effect of the Invention) As described above, according to the rail suspension device for a trolley conveyor of the present invention, it is not necessary to mount anything on the rail side, so that the assembly cost can be significantly reduced. Moreover, since the gate-shaped member can be fixed at an arbitrary position in the rail length direction according to the position of the rail suspension member on the ceiling side, the position accuracy of the rail suspension member in the rail length direction is improved. There is no need at all. Further, although the rail and the gate-shaped member can be securely and firmly connected to each other by the rail fitting groove and the bolt nut formed on the inner side plates of the gate-shaped member, the structure is extremely simple and the number of parts is also small. It is few and can be implemented very cheaply.
