[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1-6 As shown, this application provides a workshop overhead crane, including a robotic arm 1 and an overhead crane 2 with sliding parts at the bottom of the robotic arm 1. The bottom of the overhead crane 2 is provided with a hook 201.

[0027] Specifically, such as Figure 1 As shown, a balancing component 3 is provided on the top side of the robotic arm 1. The balancing component 3 is used to limit the cargo. The balancing component 3 includes a balancing element 301, which is slidably connected to the top of the robotic arm 1. Balancing belts 304 pass through both sides of the balancing element 301 and are sleeved on the outer peripheral wall of the cargo.

[0028] The bottom of the balancing component 301 is rotatably connected to a pulley 305, and the top of the robotic arm 1 is provided with a guide rail 3051, with the pulley 305 rotatably connected inside the guide rail 3051.

[0029] Specifically, such as Figure 2 As shown, the balance component 301 is equipped with an automatic winding device 302. The end of the balance belt 304 is fixedly connected to the automatic winding device 302 and is wound up. The automatic winding device 302 can wind up the balance belt 304 when the goods are lifted. The specific operation and principle of the automatic winding device 302 can be referred to the existing automatic retraction winding device with model G3050Y.

[0030] The bottom of the balance component 301 is fixedly connected to the connecting frame 303, which is fixedly installed on both sides of the overhead crane 2. The balance component 301 can be fixedly connected to the overhead crane 2 through the connecting frame 303, and the balance component 3 can be driven to move synchronously when the overhead crane 2 moves.

[0031] The end of the balance belt 304 is fixedly connected to a snap fastener 3041, which snaps onto the side wall of the balance belt 304. The side wall of the balance belt 304 is fixedly connected to an anti-slip membrane 3042, and the bottom of the balance belt 304 is fixedly connected to a traction rope 3043. The anti-slip membrane 3042 increases the friction of the balance belt 304, preventing the balance belt 304 from slipping easily. The traction rope 3043 allows for manual adjustment of the traction of goods.

[0032] Specifically, such as Figure 5 As shown, an anti-slip component 4 is provided below the hook 201. The anti-slip component 4 is used to fix the goods. The anti-slip component 4 includes a base plate 403, which is fixedly connected to the bottom of the hook 201. An anti-slip strip 401 is fixedly connected to the side wall of the base plate 403 and is sleeved on the rope of the goods.

[0033] Specifically, such as Figure 6 As shown, the anti-slip strip 401 is fixedly connected to a fixing member 402 at its end, and the side wall of the base plate 403 is provided with a fixing groove 4031, in which the fixing member 402 is inserted.

[0034] The end of the fixing member 402 has a snap-fit ​​rod 405 passing through it. The fixing groove 4031 has a snap-fit ​​groove 4021 inside. The snap-fit ​​rod 405 is snapped into the inside of the snap-fit ​​groove 4021. By passing the anti-slip strip 401 through the cargo rope suspended on the hook 201 and squeezing the snap-fit ​​rod 405 to retract it into the fixing member 402, and then inserting the fixing member 402 into the fixing groove 4031 of the base plate 403 for fixation, the cargo rope can be fixed, avoiding the cargo from sliding and tilting due to the unstable center of gravity during the suspension process.

[0035] A connecting plate 4032 is fixedly connected to the end of the snap-fit ​​rod 405. The connecting plate 4032 is slidably connected inside the fixing member 402. A return spring 404 is fixedly connected between the connecting plate 4032 and the fixing member 402. After the snap-fit ​​rod 405 is released, the snap-fit ​​rod 405 can be reset by the tension of the return spring 404. At this time, the snap-fit ​​rod 405 will be inserted into the snap-fit ​​slot 4021 for fixation.

[0036] The specific steps of this solution are as follows: First, the cargo rope is suspended from the hook 201. Then, the anti-slip belt 401 is passed through the cargo rope and retracted into the fixing member 402 by pinching the clamping rod 405. The fixing member 402 is then inserted into the fixing groove 4031 of the base plate 403 to fix the cargo rope. Next, two sets of balance belts 304 are passed through both sides of the cargo and the clamping member 3041 is clamped into the side wall of the balance belt 304 for fixation. Finally, the overhead crane 2 is driven to lift the cargo.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
