Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a heavy-duty mechanical lifting device for rail-mounted cargo handling at a railway freight station, comprising: a lifting frame 1, a chain 2 fixedly installed on the top of the lifting frame 1, the other end of the chain 2 fixedly installed on the bottom of the lifting plate 3, a lifting lug 4 fixedly installed on the top of the lifting plate 3, a permanent magnet synchronous motor 5 fixedly installed in the middle of the top of the lifting frame 1, a rotating shaft 6 fixedly connected to the output shaft of the permanent magnet synchronous motor 5, a bearing 7 installed on the outer wall of the rotating shaft 6, a rotating block 8 fixedly installed at the bottom of the rotating shaft 6, a crossbeam 11 fixedly installed at the bottom of the rotating block 8, a longitudinal beam 12 fixedly installed on the crossbeam 11, connecting parts 13 rotatably connected to both ends of the crossbeam 11, a connecting rod 14 fixedly connected to the bottom of the connecting parts 13, a gyroscope 17 fixedly installed at the bottom of the inner cavity of the lifting frame 1, and a balancing mechanism 18 fixedly installed at the bottom of the inner cavity of the lifting frame 1 and on both sides of the rotating shaft 6.

[0028] like Figure 2 and Figure 3 As shown, a limit ring 9 is fixedly installed on the top of the rotating block 8, and a locking block 10 is fixedly installed on the bottom of the hoisting frame 1. The rotating shaft 6 is driven to rotate by the permanent magnet synchronous motor 5, so that the rotating block 8 rotates. The connection between the limit ring 9 and the locking block 10 can increase the connection strength between the rotating shaft 6 and the rotating block 8, so that it can bear greater force.

[0029] like Figure 1 and Figure 2 As shown, a swivel ring 15 is rotatably connected to the outer wall of the connecting rod 14, and a hook 16 is fixedly connected to the bottom of the swivel ring 15. The rotatable connection allows the hook 16 to be better adjusted in direction, making lifting more convenient.

The balance of the lifting device during the lifting process is monitored by a gyroscope 17. When the lifting device tilts beyond the normal level, the linear motor 185 moves on the screw 184 according to the tilt displayed on the gyroscope 17, thereby driving the counterweight 187 to move in the opposite direction of the tilt.

[0031] like Figure 4 and Figure 5 As shown, the bottom of the linear motor 185 is provided with a groove that matches the support block 182. The support block 182 supports the linear motor 185, preventing all the weight from being applied to the screw 184.

[0033] like Figure 4 and Figure 5 As shown, there are two sets of balancing mechanisms 18, and the two sets are horizontally arranged on both sides of the rotating shaft 6.

[0034] The technical solution provided by this utility model monitors the balance of the lifting device during the hoisting process using a gyroscope 17. When the lifting device tilts beyond the normal level, the linear motor 185 moves on the screw 184 according to the tilt displayed on the gyroscope 17, thereby moving the counterweight 187 to the opposite direction of the tilt. The permanent magnet synchronous motor 5 drives the rotating shaft 6 to rotate, causing the rotating block 8 to rotate. The connection between the limiting ring 9 and the locking block 10 increases the connection strength between the rotating shaft 6 and the rotating block 8, enabling it to bear greater force. The rotation of the rotating block 8 allows for better hoisting of objects, and the balancing mechanism 18 helps maintain balance.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
