[0019] Example 1

[0020] See Figures 1-3An elevator-type tower crane includes a crane body 1, a moving frame 2, a latching assembly 3, and a cargo fixing assembly 4. The moving frame 2 is installed below the crane body 1, the latching assembly 3 is installed inside the moving frame 2, and the cargo fixing assembly 4 is installed at the bottom of the moving frame 2. Slide rails 5 are symmetrically welded on the outer wall of the bottom end of the crane body 1. Slide grooves 7 are symmetrically opened at the top of the moving frame 2 corresponding to the position of the slide rails 5, so that the slide grooves 7 on the moving frame 2 can move along the slide rails 5 to a designated position, facilitating the transportation of goods to the designated position. First racks 6 are fixedly connected to the outer walls of both sides of the crane body 1. First gears 9 are meshed at the bottom end of the first racks 6. First motors 8 are embedded on both sides of the moving frame 2, and one end of the output shaft of the first motor 8 is fixed to the outer wall of the first gear 9. When the first motor 8 is started, the first gear 9 rotates, and then under the action of the first racks 6, the slide grooves 7 on the moving frame 2 move along the slide rails 5 to a designated position.

[0021] The snap-fit ​​assembly 3 includes a mounting groove 301, a guide opening 302, a second motor 303, a second gear 304, a support plate 305, a rotating rod 306, a third gear 307, and a snap-fit ​​arc plate 308. The moving frame 2 has a mounting groove 301. Support plates 305 are fixedly connected to the inner walls of both sides of the mounting groove 301. A rotating rod 306 is rotatably connected to the outer wall of one side of the support plate 305, and the other end of the rotating rod 306 is rotatably connected to the inner wall of the mounting groove 301. A third gear 307 is fixedly connected to the rotating rod 306. A second gear 304 is meshed on one side of the two third gears 307.

[0022] Working principle: First, the hoisting rope is placed below the moving frame 2. At this time, the second motor 303 in the mounting slot 301 is started, causing the second gear 304 to rotate. Then, under the action of the third gear 307, the two rotating rods 306 rotate in opposite directions along the support plate 305, thereby causing the snap-fit ​​arc plate 308 to rotate along the guide opening 302, so that the snap-fit ​​arc plate 308 engages with the hoisting rope. Then, the freight elevator is lifted by the crane body 1. Then, the first motor 8 is started, causing the first gear 9 to rotate, and then the first rack 6... Under the action of the third gear 307, the sliding groove 7 on the moving frame 2 moves along the slide rail 5 to the designated position. At this time, the second motor 303 is started to make the second gear 304 rotate in the opposite direction. Then, under the action of the third gear 307, the two rotating rods 306 are reset along the support plate 305, and the buckle arc plate 308 releases the limit on the hoisting rope, so that the freight elevator can be quickly disassembled. The suspended freight elevator can be automatically buckled without the need for bolt structure for limit fixation, thereby simplifying the loading and unloading process, reducing the manpower burden, and improving the use efficiency of the equipment.

[0025] Before the goods are lifted, the third motor 402 on the vertical plate 401 is started to rotate the double-acting screw 403. Then, under the action of the threaded hole 405, the two moving blocks 404 are brought closer to each other. Then, under the action of the second rack 4015, the fourth gear 407 rotates along the rotating shaft 406, causing the rotating frame 408 to rotate downward. Then, the electromagnetic adsorption block 4010 is closed. At this time, under the action of the spring 4013, the guide rod 4012 on the limiting slide plate 4011 moves along the guide hole 409 on the rotating frame 408, so that the pressing plate 4014 presses and fixes the goods, reducing the swaying of the goods in the air. After the goods are lifted, they can be limited and fixed, reducing the swaying of the goods in the air, reducing safety hazards, and improving the use effect of the equipment.
