Background
The shaftless printing roller in the printing industry generally comprises a tubular roller body 14 with a hollow interior and plugs 15 fixed at two ends of the roller body, wherein patterns are engraved on the surface of the roller body, and plug holes 16 (shown in fig. 4 and 5) are formed in the centers of the plugs, so that a roller shaft penetrates through the plug holes and is fixedly connected with the plugs, and the roller body is driven to rotate to perform transfer printing. The printing plate roller is usually vertically stored in a warehouse, and when the printing plate roller is used, the vertical printing plate roller needs to be transversely placed on a special plate roller vehicle so as to be pulled to a printing machine for installation and use.
At present, a printing factory transversely places an upright plate roller on a plate roller special vehicle, and generally has two operation modes: one method is that one person inclines the upper end of the printing roller, the other person grasps the edge of a plug hole from the bottom of the printing roller, and the two persons combine to lift the printing roller and transversely place the printing roller on a special vehicle for the printing roller; this method is suitable for a plate roller with a weight below 300 jin, and two people lifting the plate roller with a weight above 300 jin are very laborious and unsafe. The other mode is that the plate roller is turned from a vertical state to a transverse state by a plate turning machine, and then the plate roller is transferred to a special plate roller vehicle; because the plate turning machine is operated, the plate roller is turned from vertical to horizontal by virtue of the expansion of the electric push rod, at present, no high-power push rod is sold in China, the used push rod is generally produced by a medical instrument factory and used for turning a sickbed, the power is very low, the weight of the plate roller is too large, the electric push rod of the plate turning machine is easy to damage, the electric push rod needs to be purchased and replaced again, and the production cost is increased.

Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The printing roller gantry crane shown in the figure comprises two bases 2, two columns 9, a cross beam 10 and two groups of lifting assemblies.
A plurality of (four in the figure) rollers 1 are arranged at the bottom of each base, so that the gantry crane can conveniently move; a brake pedal 4 which can swing in a vertical plane is hinged on the base, and a return spring 3 is connected between the brake pedal and the base; when the device is used, a worker steps the brake pedal on the ground, so that the situation that the gantry crane moves in the process of lifting the plate roller is avoided, and the brake pedal automatically resets under the action of the reset spring after the brake pedal is released.
The two upright posts are respectively vertically fixed on the two bases; all be connected with between every stand lower part and the base that corresponds and consolidate arm 5 to increase the support strength of stand. The cross beam is horizontally fixed at the tops of the two stand columns, so that the cross beam and the two stand columns form a door shape.
And the two groups of lifting components are respectively arranged at two ends of the cross beam and used for lifting the printing roller. Two sets of hoisting components are the same in structure, and each set of hoisting component comprises a winch 11, a steel wire rope 12 and a supporting iron bar 13. The winch is fixed on the cross beam; an ascending button 8, a stopping button 6 and a descending button 7 are arranged on the two upright posts to respectively control the working states of the two winches. One end of the steel wire rope is wound on the winch, and the other end of the steel wire rope freely hangs. The supporting iron strips are fixed at the hanging ends of the steel wire ropes, and the steel wire ropes are fixedly connected to the middle positions of the supporting iron strips in the length direction, so that the steel wire ropes are guaranteed to apply force to the middle of the supporting iron strips. The width of the supporting iron strip is smaller than the diameter of the plug hole 16 of the plate roller, so that the supporting iron strip can extend into the plate roller; the length of the supporting iron bar is larger than the diameter of the plug hole of the printing roller and smaller than the inner diameter of the roller body 14 of the printing roller, so that the supporting iron bar cannot slide out of the plug hole when being transversely blocked at the plug hole.
