Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a gantry frame for a bar stacking and hoisting equipment, comprising: The gantry frame body 101 and the crossbar 102 are equipped with a movable hook on the gantry frame body 101 to hang the crossbar 102. The flexible gripping component includes a T-shaped frame 201, a first hinge block 202, a support claw 203, a receiving rod 204, a second hinge block 205, a telescopic hydraulic cylinder 206, a third hinge block 207, and a clamping rod 208. The T-shaped frame 201 is fixedly connected to the crossbar 102. One end of the first hinge block 202 is fixedly connected to both ends of the crossbar 102. The other end of the first hinge block 202 is hinged to the support claw 203. The receiving rod 204 is fixedly connected to the support claw 203. One end of the second hinge block 205 is fixedly connected to both ends of the T-shaped frame 201. The other end of the second hinge block 205 is hinged to one end of the telescopic hydraulic cylinder 206. The other end of the telescopic hydraulic cylinder 206 is fixedly connected to one end of the third hinge block 207. The other end of the third hinge block 207 is hinged to the receiving rod 204. The clamping rod 208 is movably connected to the support claw 203. The support claws 203 are arranged at equal intervals. The T-shaped frame 201 on the crossbar 102 ensures the connection of the second hinge block 205. The first hinge block 202 ensures the rotation of one end of the support claw 203. The structure formed by the support claw 203, the receiving rod 204, and the clamping rod 208 is used to support and place the bar, thereby facilitating the stacking and retrieval of the bar. The second hinge block 205 ensures the movable connection of the telescopic hydraulic cylinder 206. The telescopic hydraulic cylinder 206 and the third hinge block 207 ensure the lifting and lowering of the support claw 203.

[0018] Working principle: If the bar is relatively long, all telescopic hydraulic cylinders 206 are opened. With the cooperation of the first hinge block 202, the second hinge block 205, and the third hinge block 207, all support claws 203 are lowered and unfolded. Then, with the cooperation of the receiving rod 204 and the clamping rod 208, the bar is hooked and placed. Then, the lifting switch on the gantry frame body 101 is opened, which moves the crossbar 102 upward, thereby moving the bar upward. Then, the displacement switch on the gantry frame body 101 is opened, which moves the bar to the top of the material rack. Then, the bar is lowered and placed on the material rack. When taking out a bar of the corresponding length, the above process is repeated in reverse. If the bar is relatively short, several telescopic hydraulic cylinders 206 are opened so that the length between the lowered support claws 203 is close to the length of the bar. When taking out a short bar, only several telescopic hydraulic cylinders 206 need to be opened.

[0019] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The adaptive adjustment assembly includes a strip guide groove 301 and a guide rod 302. The support claw 203 has a strip guide groove 301. The bottom of the clamping rod 208 is fixedly connected to the guide rod 302. The guide rod 302 is movably connected in the strip guide groove 301. The adaptive adjustment assembly also includes a limiting block 303. The bottom of the guide rod 302 is fixedly connected to the limiting block 303. The limiting block 303 is movably connected to the bottom end of the support claw 203. The guide rod 302 and the strip guide groove 301 work together to ensure the sliding of the clamping rod 208. The limiting block 303 can limit the clamping rod 208 to prevent it from falling off the support claw 203.

[0020] The adaptive adjustment assembly also includes a threaded groove 304, a motor 305, and a threaded rod 306. The threaded groove 304 is opened through the middle of the limiting block 303. The bottom end of the support claw 203 is fixedly connected to the motor 305. The output end of the motor 305 is connected to the threaded rod 306. The threaded rod 306 is movably connected to the threaded groove 304. The motor 305 provides kinetic energy for the rotation of the threaded rod 306 in the threaded groove 304, thereby ensuring the movement of the clamping rod 208. The clamping rod 208 and the receiving rod 204 work together to further clamp and limit the bar placed by the support claw 203, preventing the bar from falling off during stacking and retrieval.

[0021] The adaptive adjustment component also includes an anti-slip strip 307, which is fixedly connected to the clamping rod 208; the anti-slip strip 307 has a trapezoidal cross-section. The anti-slip strip 307, with its trapezoidal cross-section, can be inserted into the gap between individual bars in a bundle, thereby further providing a tighter and more secure hold on the bundled bars and effectively preventing them from wobbling and slipping.

[0022] Working principle: When stacking and picking up the bars, when the bars are hooked to the top of the support claw 203, the motor 305 is turned on, which drives the threaded rod 306 to rotate at the threaded groove 304. With the cooperation of the guide rod 302 and the strip guide groove 301, the clamping rod 208 will move towards the receiving rod 204 until the clamping rod 208 contacts the bar and applies a certain external force to it. At this time, the anti-slip strip 307 is inserted into the gap of the bundled bars.
