を支持せしめた搬送装置に関するものである。[Detailed description of the invention] This invention supports the center position in the width direction at two locations in the front and back of the load support platform by a pair of front and rear trolleys that are movably supported between a pair of opposing U-shaped guide rails. The present invention relates to a conveyance device.

置を提供せんとするものである。 The biggest problem with this type of conveyance device is that the load support platform is unstable in the lateral direction. In conventional conveying devices of this kind, in order to prevent the load support from rolling, a steady rest guide is used to support a horizontal shaft roller for a steady rest that is pivotally supported near the widthwise end of the load support. Although the rails were constructed separately from the trolley running guide rails, the present invention provides a conveyance device that can achieve the intended purpose without using the above-mentioned guide rails dedicated to resting the load support platform. This is what I am trying to do.

になる。 In the conveying device configured as described above, the pusher 21 of the drive trolley 20 engages with the driven pawl 19 of the leading trolley 4 as shown in the figure, so that the four trolleys 2 to 5 and the load support platform 1 A transport carriage consisting of the following is made to travel along guide rails 6a and 6b. Universal joints 10a, 10b and 12a, 12b are provided at both ends of the connecting rods 11, 13.
is interposed, the load support 1 can be rotated about the vertical axis 14 relative to the trolleys 2, 3, and the load support 1 can be rotated around the pin 16 relative to the trolleys 2, 3. By being able to swing up and down, the carrier can smoothly travel on horizontal curved paths and vertical curved paths. In this way, the conveyance work is carried out by supporting the conveyed object on the load support platform 1 of the conveyance vehicle that can travel along a fixed route. Normally, a pair of front and rear and a pair of upper and lower vertical shaft rollers 8 and 9 for steady rests, which are pivotally supported by trolleys 2 and 3 that support the front and rear of the load support platform 1, are mounted on the upper and lower sides of a pair of left and right guide rails 6a and 6b. This is prevented by fitting between the opposing side edges on both sides. If the load support platform 1 is shaken significantly beyond the permissible range during transport, the pair of left and right horizontal shaft rollers for steady rest, which are pivotally supported by the trolleys 2 and 3, should be removed. By bringing one of the guide rails 6a, 6b into contact with the upper surface of one of the guide rails 6a, 6b, the load support platform 1 is prevented from swinging unreasonably.

出来る。 Furthermore, the horizontal axis roller 27 or 28 for steadying may be pivotally supported on only one of the trolleys 2 and 3 that support the front and rear of the load support platform 1. In addition, horizontal shaft rollers 27, 2 for steadying are provided on the load support platform 1 side.
8, the roller may be supported only on one of the front and rear ends of the load support platform 1, or it may be supported at an intermediate position.

行経路の際まで有効利用出来るのである。 The conveyance device of the present invention can be implemented and used as described above, and is carried at two locations, front and rear of the load support platform, by a pair of front and rear trolleys movably supported between a pair of opposing U-shaped guide rails. In the conveying device, a horizontal axis roller located above each of the upper surfaces of the pair of guide rails is mounted on at least one of the pair of front and rear trolleys or on the load support platform. and these horizontal axis rollers are pivoted at a height that slightly floats above the upper surface of the guide rail when the load support platform is in a horizontal position.
Only when the load support platform 1 is in a situation where it is abnormally swaying, the horizontal axis roller is brought into contact with the upper surface of the pair of guide rails for running the trolley to prevent the load support platform from lateral shaking; Normally, the horizontal axis roller is floated above the guide rail, allowing the load support platform to run smoothly without providing any extra resistance. Moreover, there is no need to separately install a dedicated guide rail to prevent the load support platform from rolling in cooperation with the horizontal axis roller, which is economical, and the floor surface can be effectively used even during the trolley travel path. It is.
