[0022] A gantry composite machine plate roller loading and unloading tooling, comprising: a base 111, a loading and unloading structure 2 is arranged above the base 111, and a stabilizing structure 3 is arranged at the bottom end of the base 111. The loading and unloading structure 2 includes a frame body 211, the frame body 211 is fixedly arranged at the upper end of the base 111, a manual hydraulic jack 212 is fixedly connected to the upper part of the middle of the base 111, a connecting shaft 213 is fixedly connected to the upper end of the manual hydraulic jack 212, gears 214 are fixedly connected to both ends of the connecting shaft 213, a chain is arranged on the gears 214, one end of the chain on the gear 214 is fixedly connected to a connecting long arm 215, and the other end of the chain on the gear 214 is fixedly connected to the base 111. The connecting long arm 215 is slidably arranged inside the base 111, a nylon support plate 216 is installed at the upper end of the connecting long arm 215, and the upper end of the nylon support plate 216 is arc-shaped. Through this design, when using this gantry composite machine plate roller loading and unloading tooling, it is moved to the position of the gantry composite machine plate roller, the manual hydraulic jack 212 is manually controlled to drive the connecting shaft 213 to rise, and then drive the gears 214 to rise synchronously. Under the action of the chain on the surface of the gears 214, the connecting long arms 215 are synchronously driven to rise, so that the nylon support plate 216 contacts and supports the gantry composite machine plate roller, and the gantry composite machine plate roller is supported and removed by the nylon support plate 216, and it can be conveniently transported and moved.

[0023] Further, a fixing rod 217 is installed between two groups of nylon support plates 216, and a rubber ring 218 is installed on the fixing rod 217. Through this design, the friction between the rubber ring 218 installed on the fixing rod 217 and the plate roller of the gantry compound machine can be increased, making it more stable when placed on the nylon support plate 216.

[0024] Further, a connecting rod 219 is fixedly connected to the upper end of the base 111, and a push rod 220 is fixedly connected to the upper end of the connecting rod 219. Through this design, when moving this loading and unloading tooling, the push rod 220 can be held by hand to push, making the pushing more convenient.

[0025] Further, the stable structure 3 includes universal wheels 311 which are fixedly arranged at the bottom end of the base 111. A threaded rod 312 is rotatably arranged inside the base 111. A screw sleeve 313 is threadedly connected to the surface of the threaded rod 312. A support rod 314 is fixedly connected to the outer wall of the screw sleeve 313. A support plate 315 is fixedly connected to the bottom end of the support rod 314. Through this design, when the loading and unloading tooling is not in use, the threaded rod 312 can be rotated. Under the action of the thread, the screw sleeve 313 is driven to move, and then the support rod 314 is driven to move synchronously. Finally, the support plate 315 is driven to move synchronously to make it contact the ground for support, so that the loading and unloading tooling can be kept stable when not in use.

[0026] Further, a slider 316 is fixedly connected to the side wall of the screw sleeve 313. The slider 316 is slidably arranged inside a chute 317 which is opened inside the base 111. Through this design, when the screw sleeve 313 moves, the slider 316 moves synchronously inside the chute 317 to realize the limiting effect on the screw sleeve 313, making its movement more stable.

[0027] Further, a rubber pad is arranged at the bottom end of the support plate 315. Through this design, a rubber pad is arranged at the bottom end of the support plate 315 to increase the friction between the bottom end of the support plate 315 and the ground, so that it will not slip when supporting.

[0028] Working principle:

[0029] When using this loading and unloading tooling for the gantry compound machine plate roller, move it to the position of the gantry compound machine plate roller, manually control the manual hydraulic jack 212 to drive the connecting shaft 213 to rise, and then drive the gear 214 to rise synchronously. Under the action of the chain on the surface of the gear 214, the connecting long arm 215 is synchronously driven to rise, so that the nylon support plate 216 contacts and supports the gantry compound machine plate roller. The gantry compound machine plate roller is supported and removed by using the nylon support plate 216, and it can be conveniently transported and moved. The friction between the rubber ring 218 installed on the fixing rod 217 and the gantry compound machine plate roller can be increased, making it more stable when placed on the nylon support plate 216.

[0030] When the loading and unloading tooling is not in use, the threaded rod 312 can be rotated. Under the action of the thread, the nut sleeve 313 is driven to move, and then the support rod 314 is driven to move synchronously, and finally the support plate 315 is driven to move synchronously, so that it contacts the ground for support, enabling the loading and unloading tooling to remain stable when not in use. A rubber pad is provided at the bottom end of the support plate 315 to increase the friction between the bottom end of the support plate 315 and the ground, so that it will not slip during support. Thus, the operation ends.
