Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rack connection structure for a monorail with a rack.

[0002]

2. Description of the Related Art Conventionally, a connecting portion between rack-mounted monorails is constructed such that an eye plate or the like is straddled between the ends of both rack-mounted monorails, and these rack-mounted monorails are connected. I have to.

[0003]

However, in the above-described connection structure, the relative positions of the two racks cannot be regulated accurately, so that the pitch of the racks at the connection portion is out of order, and the connection of the pinions meshed with the racks. Normal operation at the time of passing through the rack section, and in severe cases, there is a problem that the pinion idles or the teeth at the end of the rack are chipped.

[0004]

Accordingly, the present invention provides a rack connection structure for a monorail with a rack, wherein at least one tooth having the same shape as the rack is provided at two rack ends.
A rack connection structure is provided in which a connection receiving member formed in a mountain-like manner is fixed, and a connection rack having at least three teeth is fixed in a detachably meshing state across both connection receiving members. It is assumed that.

[0005] The present invention also has the following features.

The back surface of the rack is fixed to the inner surface of one side of a long member having a substantially L-shaped cross section disposed along the rail, and the connection receiving member is attached to the outer surface of the other side of the long member. Stuck.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention are as follows.

A monorail is formed by fixing a connecting member between two vertically arranged square pipes at a predetermined interval, and a long material having a substantially L-shaped cross section is formed below one side of the upper square pipe. A rack formed with the teeth facing downward on one side lower surface of the same long material and fixed along the same angle pipe, along the long material, and
The rack is fixed so that the end of the rack is located at the center of the tooth valley to form a monorail with a rack.

[0009] On the other outer surface of both ends of the long material, a connection receiver having teeth of the same shape as the rack is formed one by one. By connecting the connection rack with the eye plate fixed to both connecting straddles, and connecting and detachably fixing the connection rack with the bolts inserted through the eye plate, the monorail with two racks can be connected. Easy connection and disconnection.

[0010] In particular, by engaging the connection receiving members with the connection racks, it is possible to form a series of racks by accurately maintaining the relative positions of both racks of the monorail with two racks. The acting longitudinal load is supported by the meshing so that the series of rack shapes can be maintained for a long period of time.

[0011]

Embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a rack connection structure of a monorail with a rack according to the present invention. First, a monorail M with a rack to be connected will be described, and then a connection structure will be described.

In the monorail M with a rack, a large number of connecting members 3 are bridged between upper and lower rectangular pipes 1 and 2 which are arranged in parallel with a predetermined interval therebetween to form a monorail body M1 having a predetermined length.

On the other hand, a back surface of a rack R extending in the longitudinal direction of the long material 4 is fixed to one inner side surface of the long material 4 having a substantially L-shaped cross section and the same length as the monorail body M1. The outer surface of the long member 4 on the side where the rack R is not fixed is fixed to the side surface of the connecting member 3, and the lower surface outer edge of the upper square pipe 1 is attached to the upper inner edge of the long member 4. The rack R with the teeth 5 facing downward is fixed and arranged in parallel with the monorail body M1.

Further, at the end of the monorail M with a rack, the upper and lower square pipes 1 and 2, the long material 4 and the rack R
Are located on the same plane orthogonal to the monorail M with the rack. In particular, the end face of the rack R is located at the center of the valley 6 of the tooth 5, and the end face is located at the peak 7 of the tooth 5. In this case, the strength of the teeth 5 is prevented from being reduced.

FIGS. 1 to 4 show a connection structure for a monorail with a rack. The connection structure mainly includes a connection receiving member 8 on the monorail M side with a rack and a connection rack r separately provided. Have been.

As shown in FIGS. 3 and 4, the connection receiver 8 has only one crest 7 of the teeth 5 having the same shape as the rack R, and the rack R at the end of the long material 4 is formed. The teeth 5 are fixed to the outer surface on the side not fixed to the rack R in the same phase as the rack R, and the stud bolt 9 is set up inside the connection receiving member 8 on the outer surface. Has been established.

As shown in FIGS. 3 and 4, the connection rack r has only three peaks 7 of teeth 5 having the same shape as the rack R, and a mounting plate 10 is provided on the back surface of the connection rack r. At both ends of the mounting plate 10, a bolt insertion hole 11 for inserting the stud bolt 9 is formed.

When connecting the monorails M with racks, the two monorails M with racks are arranged in abutting fashion, and the mutual interval between the ridges 7 of the connection receiving members 8 is matched with the pitch of the rack R. Then, while inserting each stud bolt 9 into each bolt insertion hole 11 of the mounting plate 10, the peak 7 of the tooth 5 of each connection rack r is inserted into the valley 6 of the connection receiving member 8 and meshed with each other. Screw nut 12 onto bolt 9
Then, both racks R are connected (see FIGS. 3 and 4). In the figure, reference numerals 13 and 14 denote eye plates and bolt nuts for connecting the lower square pipe 2.

As described above, the connection receiver 8 having the teeth 5 having the same shape as the rack R and being fixed to each rack R in the same phase.
And the connection between the two racks R through meshing with the connection rack r having the teeth 5 having the same shape as the racks R, the racks R at the connection portions can maintain the shape as a series of racks R, In addition, both racks R can be firmly connected, and a normal rack shape can be maintained for a long period of time.

The connection structure of a monorail with a rack according to the present invention is applied not only to a connection portion of a monorail with a rack laid on an inclined ground, but also to a guide rail with a rack vertically installed in a vertical hole excavated in the ground. be able to.

[0022]

According to the present invention, the following effects can be obtained.

According to the first aspect of the present invention, there is provided a connection structure for a monorail with a rack, wherein a connection receiving member having at least one crest formed with at least one tooth having the same shape as the rack is fixed to two rack ends. By fixing a connection rack having at least three ridges in a detachably meshing state over both connection receiving members, the relative positions of both racks are accurately held, and the pitch of the teeth of the rack is irregular. The operation of the pinion meshing with the rack can be maintained smoothly for a long period of time, and since the connection rack is detachable, the connection work for laying a monorail with a rack and the removal of Separation work can be facilitated.

According to the second aspect of the present invention, the back surface of the rack is fixed to the inner surface of one of the long members having a substantially L-shaped cross section disposed along the rail, and the connection receiving member is fixed to the long side. The structure is simplified by being fixed to the outer surface of the other side of the length member, avoiding the interference between the connection holder and the connection rack and the pinion meshed with the rack, and hindering the operation of the pinion. Can be prevented.
