Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides as Figures 1-5A new Chinese-style electric single-girder crane shown in the figure includes a crossbeam 1, a hook 8, a lifting rope 7, and sliding plates 9 fixedly connected to both ends of the crossbeam 1. A traveling trolley 4 is slidably connected to the crossbeam 1. One side of the traveling trolley 4 is fixedly connected with a driving member 5, and the driving member 5 can control the displacement of the traveling trolley 4. The bottom surface of the traveling trolley 4 is fixedly connected with an installation box 6. An anti-sway assembly 3 capable of moving up and down with the heavy object is provided on the installation box 6. A transmission assembly 2 capable of promoting the up and down movement of the anti-sway assembly 3 is provided inside the installation box 6. Through the transmission assembly 2, the anti-sway assembly 3 can be controlled to move up and down, so that the anti-sway assembly 3 is always above the goods being lifted, thereby performing all-round limiting on the lifting rope 7 and the goods on the lifting rope 7, so that the goods are less swayed greatly when being lifted and moved, and then the effect of protecting the safety of the ground staff is achieved.

[0026] As Figure 1 and Figure 3 shown in the figure, the transmission assembly 2 includes a motor 201. One side of the motor 201 is fixedly connected with one side of the installation box 6. The output end of the motor 201 penetrates through one side of the surface of the installation box 6 and extends into the interior of the installation box 6. The output end of the motor 201 is fixedly connected with a transmission rod 204. The end of the transmission rod 204 away from the motor 201 is rotatably connected with one side of the inner wall of the installation box 6. The transmission assembly 2 further includes two driving bevel gears 205 and two fixed blocks 202 fixedly connected to the bottom surface of the inner wall of the installation box 6. The inner walls of the two driving bevel gears 205 are fixedly connected to the rod wall of the transmission rod 204. The bottom surfaces of the two driving bevel gears 205 are meshed with driven bevel gears 203 respectively, and the driven bevel gears 203 can rotate following the driving bevel gears 205.

[0027] As Figure 2 、 Figure 4 and Figure 5As shown in the figure, the anti-sway component 3 includes two lead screws 302. The tops of the two lead screws 302 are fixedly connected to the bottom surfaces of the corresponding driven bevel gears 203. The bottoms of the two lead screws 302 penetrate through the corresponding fixed blocks 202 and extend to the bottom surface of the installation box 6. A common anti-sway plate 304 is threadedly connected to the rod walls of the two lead screws 302 located on the bottom surface of the installation box 6. The bottoms of the two lead screws 302 are fixedly connected with anti-drop blocks 305, and the anti-drop blocks 305 prevent the anti-sway plate 304 from falling off. The anti-sway component 3 further includes two first fixing rods 301 and two second fixing rods 303. The two first fixing rods 301 and the two second fixing rods 303 are all rigid rods, so as to be able to fix the anti-sway plate 304. The tops of the two first fixing rods 301 are fixedly connected to the bottom surface of the installation box 6. The bottoms of the two second fixing rods 303 are fixedly connected to the top surface of the anti-sway plate 304. The rod walls of the two first fixing rods 301 are slidably connected to the inner walls of the corresponding second fixing rods 303 respectively. The thread pitches of the two lead screws 302 are opposite and the same. The two lead screws 302 are both installed inside the corresponding first fixing rods 301 and second fixing rods 303. The inner walls of the two first fixing rods 301 are fixedly connected with support blocks 12, and the two support blocks 12 can support the two lead screws 302. The inner walls of the two support blocks 12 are rotatably connected to the rod walls of the corresponding lead screws 302.

[0028] As Figure 5 shown, a moving groove 10 is formed on the surface of the anti-sway plate 304. A plurality of balls 11 are rotatably connected to the inner wall of the moving groove 10, and the balls 11 can prevent the lifting rope 7 from rubbing against the moving groove 10 and causing wear to the lifting rope 7.

[0029] As Figure 2 shown, a winding drum 13 is fixedly connected to the rod wall of the transmission rod 204. The winding drum 13 can wind and release the lifting rope 7, so as to achieve the effect of lifting the goods. The lifting rope 7 is wound around the surface of the winding drum 13. The bottom end of the lifting rope 7 penetrates through one side of the installation box 6 and passes through the moving groove 10 and is fixedly connected to the top end of the hook 8.

[0030] Working principle of the utility model: When the device is in use, first start the motor 201, and then the motor 201 drives the transmission rod 204 to rotate, thereby driving the winding drum 13 to rotate. As the winding drum 13 rotates, the lifting rope 7 on the winding drum 13 can be released, so that the hook 8 can be lowered, thus facilitating the connection of the hook 8 to the goods. At the same time when the transmission rod 204 rotates, it can drive the two driving bevel gears 205 to rotate. Then, when the two driving bevel gears 205 rotate, they can control the two driven bevel gears 203 to rotate synchronously. As the two driven bevel gears 203 rotate, they can drive the two lead screws 302 to rotate. As the two lead screws 302 rotate, the anti-sway plate 304 can move downward along the rod wall of the lead screw 302, so that the anti-sway plate 304 can always be above the hook 8 to limit the lifting rope 7 above the hook 8;

[0031] After the hook 8 is connected to the goods, start the motor 201 to rotate in the reverse direction, thereby driving the winding drum 13 to wind up the lifting rope 7. At the same time when the lifting rope 7 is being wound up, the two lead screws 302 can also rotate, causing the anti-sway plate 304 to move upward. At the same time when the anti-sway plate 304 moves upward, the first fixing rod 301 can contract into the second fixing rod 303. Thus, the anti-sway plate 304 is limited by the arrangement of the first fixing rod 301 and the second fixing rod 303, and then the lifting rope 7 and the goods on the hook 8 are limited to prevent the problem of the goods shaking when being lifted. The original text highlights the innovative structure and does not elaborate too much on the prior art.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
