In addition to the above-mentioned chain drive, the lifting frame 14 can be guided up and down by a jack type, electric drive, or hydraulic system in which a nut that is prevented from vertical movement is screwed onto a vertical screw shaft fixed to the lifting frame 14 and the nut is rotationally driven. Any known device may be used, such as a driven pantograph-type lifting mechanism.

Both sides of the elevating frame 14 serve as horizontal rails 21, and a roller 23 is pivotally supported between a pair of support fittings 22 fixed to both front sides of both frames 21, respectively. The upper traveling frame 24 has a rectangular frame shape with the same width as the elevating frame 14, and its both sides 2
The front part of 5 is supported on rollers 23 and is prevented from moving laterally by support fittings 22. Said both sides 25
The rear part of the roller 27 is supported on the horizontal rail 21 by a roller 27 which is pivotally supported by the upper end of a support fitting 26 fixed thereto, and is suspended from the horizontal rail 21 with horizontal movement being prevented by the support fitting 26. With the support structure described above, the traveling frame 24 is suspended from the lower part of the elevating frame 14 horizontally and can be moved back and forth with the guide.
6 can be moved forward by hand until it hits a stopper 28 located approximately in the center of the horizontal rail 21.

A support structure similar to that described above is provided at the lower part of the upper traveling frame 24, so that the lower traveling frame 29 can be horizontally guided and moved back and forth. That is, the support metal fittings 30, 31 are provided on both sides of the lower traveling frame 29.
It is suspended from the upper traveling frame 24 by rollers 32 and the like, and can be pushed forward by hand until the support fitting 31 hits the stopper 33.

With the above structure, the traveling frames 24 and 29 can double expand and contract in the front and rear directions with respect to the lifting frame 14, but a third traveling frame with a similar support structure is provided below the traveling frame 29 to create a triple expandable structure. You can also.

Arms 34 fixed to both sides of the lower traveling frame 29
An elevating trolley rail 35 with a circular cross section extending in the front-rear direction is fixed, and the front portions of both rails 35 are connected by a semicircular rail 36, which is supported by an arm 37.

An arm 38 protruding outward from the elevating trolley rail 35 is fixed to the horizontal rail 21 of the elevating frame 14 at a necessary location in front of the stopper 28,
As shown in FIG. 4, the trolley rail 4 is connected in the front and rear direction by a C-shaped metal fitting 39 suspended from an arm 38.
Supports 0. A drop switch 42 is connected to the front end of the trolley rail 40 via a curved rail 41, and its tip is slidably connected to a straight portion of an elevating trolley rail 35 that moves back and forth. Further, the rear end of the trolley rail 40 is connected to the front end of a trolley rail 44 fixed to the ceiling via a telescoping rail 43, so that when the elevating frame 14 is raised or lowered, the telescoping rail 40

As shown in FIG. 5, the telescopic rail 43 includes a tubular tilting rail 45, a sliding rail 46 that can be tightly fitted and slid therein, and a connecting rail 47 that is press-fitted and fixed to the outer end of the tilting rail 45. and has rail 45
The outer diameter of the inner end portion of the sliding rail 46 gradually decreases in a tapered shape and approaches the inner end outer diameter of the sliding rail 46, and the outer diameter of the outer end portion of the sliding rail 46 gradually increases in a tapered shape and approaches the outer diameter of the inner end portion of the sliding rail 46. It has the same diameter as the outer end. A narrow diameter portion 48 is formed at the outer end of the sliding rail 46 and the connecting rail 47, and a hinge portion 49 protruding to a smaller width is formed at the outer end thereof, while the ends of the connecting trolley rail 40 and the fixed trolley rail 44 are formed. A connecting rail 50 is press-fitted and fixed at the end of the rail 50, and a narrow diameter section 51 having the same diameter as the narrow diameter section 48 and a fork section 52 at the tip thereof are formed at the end of the rail 50. A hinge part 49 is inserted into the fork part 52 and connected with a pin so that it can be bent, and a flexible tube 53 whose both ends are fitted into the narrow diameter parts 48 and 51 covers the pin connection part to allow the trolley T to pass smoothly. .

With the above structure, the rails 45 and 46 slide against each other as the height of the lifting frame 14 changes, and the total length changes, thereby maintaining the connection between the fixed trolley rail 44 and the connecting trolley rail 40.

When a car to be loaded with goods stops in front of the rail 36, the semicircular rail 36 is brought close to the trolley rail inside the car at the same height by raising and lowering the elevating frame 14 and manually pushing the traveling frames 24 and 29. Objects are transferred by changing hangers between both rails.

Effects of the invention This invention has the above configuration, and is located between a fixed trolley rail and a movable trolley rail, so that both trolley rails can be easily brought close to each other regardless of height difference or distance, making it easy to transfer objects. It has a smoothing effect and can streamline the work of transferring goods between any vehicle or container equipped with a moving trolley rail and a fixed trolley rail.
