Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bogie drive device having passive pins on the sides.

A conventional truck driving device has a drive chain disposed directly below the position of the driven pin, and a drive protrusion erected from the drive chain engages with the driven pin from below. According to this conventional type, the installation height of the drive chain and the like is high, and the drive chain and the like are provided along the entire length of the path, resulting in an increase in the size of the entire equipment. In addition, there is a risk that the drive chain may fly upward due to the reaction force during the drive.

The present invention is a bogie drive device having a driven pin on the side, which includes a drive chain with its connecting pin vertically arranged, and a drive chain that is integrated with the upper link plate of the drive chain and is horizontal to the driven pin. A drive protrusion that can be engaged from any direction, a lateral vibration prevention roller attached to the connecting pin between the link plates in the vertical direction, a pair of left and right guide rails that guide this lateral vibration prevention roller, and the lower surface of the lower link. It consists of a running roller attached to the roller and a running rail that guides the running roller, and a flange body is integrally formed at the bottom of the lateral vibration prevention roller, and the flange body is positioned below both guide rails. This paper proposes a trolley drive device configured to:
The installation height of the drive chain, etc. can be lowered, the entire equipment can be made smaller, and the drive chain can be prevented from flying upward.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIG. 1, a main bogie line 1 and a branch bogie line 2 are formed on the floor side. . The bogie 4 has driven pins 5A and 5B at the lower portions of both sides, and when the driven pin 5A on one side engages with the main drive device 11 side, the bogie 4 travels on the main bogie line 1, and the driven pin 5B on the other side
is engaged with the branch drive device 12 side, thereby traveling the branch bogie line 2. As shown in FIGS. 2 to 4, the truck 4 has a main body 7 having a plurality of wheels 6.
Object support sections 8 are provided at various locations on the upper surface of the main body 7. An automobile body (object to be transported) 10 is passed to this trolley 4 from a hanger 9 on the suspension transport device side. As shown in Figure 2, the main drive unit 1 is distributed to both sides of the bogie travel path.
1 and a branch drive device 12 are provided.

Next, details of the main drive device 11 will be explained based on FIGS. 5 to 8, and the branch drive device 12 side has a symmetrical structure. Brackets 13 are erected from the floor at appropriate intervals, and a pair of left and right passive pin guide rails 14A,
14B is attached. These driven pin guide rails 14A, 14B actually guide the roller 15 attached to the driven pin 5A, and their cross-sectional shape is square or square. By adopting such a shape, it is possible to prevent the passive pin 5A from being caught. The passive pin guide rails 14A, 14B
A drive chain 16 is disposed at the outer lower part of the engine, that is, at a diagonally lower position. This drive chain 16 is arranged with the connecting pin 17 oriented vertically, and thus the link group consists of an upper link 18A and a lower link 18B. A lateral vibration prevention roller 19 is attached to each connecting pin 17 between both links 18A, 18B, and a flange body 20 is integrally formed at the lower part of this lateral vibration prevention roller 19. A drive protrusion 21 is integrally formed in the lateral direction from a suitable upper link 18A, and this drive protrusion 21 is connected to the driven pin 5A.
can be engaged from the lateral direction. A runaway prevention projection 23 is swingably attached to the upper link 18A via a vertical shaft 22 at a position slightly above the part where the drive projection 21 is connected, and this runaway prevention projection 23 is urged to protrude by a spring 24. At the same time, its maximum protrusion position is regulated by a stopper 25. A pair of left and right guide rails 26A, 26B that guide the lateral vibration prevention roller 19 are attached to the bracket 13 side, and these guide rails 26A, 26B
The flange body 20 is disposed below the flange body 20. Any of the lower links 18B include:
Running rollers 28 are attached via support members 27, and running rails 29 for guiding these running rollers 28 are attached to the bracket 13 side.

First, the car body 1 is moved between the bogie 4 and the hanger 9.
0 is exchanged. In this state, the drive chain 16 of the main drive device (or branch drive device) 11
is driven, and the driving protrusion 21 is laterally engaged with the driven pin 5A. As a result, the truck 4 receives the driving force from the drive chain 16 and travels.
During the driving movement, the drive chain 16 is moved so that the lateral vibration prevention roller 19 is on both guide rails 26A, 26B.
Since the flange body 20 is guided by the guide rails 26A and 26B, no lateral vibration occurs, and since the flange body 20 contacts both guide rails 26A and 26B from below, no protrusion (floating) occurs. Further, the drive chain 16 is guided in running by rolling rollers 28 rolling on running rails 29 .

According to the bogie drive device of the present invention having the above configuration, the drive protrusion is laterally engaged with the driven pin, so that the installation height of the drive chain and the like can be lowered, and the entire equipment can be downsized. Furthermore, since the flange body integrated with the lateral shake prevention roller is received on the lower surface of both guide rails, it is possible to prevent the drive chain from flying upward due to reaction force during drive running. By using a guide rail with a square or square cross-section to guide the driven pin,
It is possible to prevent the passive pin from getting caught.
