[0065] Example 3

[0066] Reference Figure 1 - Figure 5 The third embodiment of the present invention further provides a lifting unit 200 based on the first embodiment, including a slide rail 201 arranged on the inner wall of the mounting plate 101, a lifting motor 202 arranged on the top of the slide rail 201, a slider 203 slidably arranged on the inner wall of the slide rail 201, a threaded rod 204 threadedly arranged on the inner wall of the slider 203, and a mounting frame 205 arranged between two adjacent sliders;

[0067] The threaded rod 204 is rotatably connected to the inner cavity of the slide rail 201 , and the threaded rod 204 is fixedly connected to the top end and the output end of the lifting motor 202 .

[0068] It should be noted that the lifting unit 200 includes a slide rail 201 fixedly welded to the inner side of the mounting plate 101, a slider 203 is slidably connected to the inner wall of the slide rail 201, a threaded rod 204 is also rotatably connected inside the slide rail 201, and the threaded rod 204 and the slider 203 are threadedly connected, a lifting motor 202 is fixedly connected to the top of the slide rail 201, the output end of the lifting motor 202 is fixedly connected to the threaded rod 204, and the two ends of the mounting frame 205 and the inner sides of the two sliders 203 are fixedly welded.

[0069] When in use, the lifting motor 202 is started, and the lifting motor 202 drives the threaded rod 204 to rotate. Since the threaded rod 204 and the slider 203 are threadedly connected, the threaded rod 204 can drive the slider 203 to slide in the slide rail 201 when it rotates, thereby driving the mounting frame 205 to rise and fall.

[0070] In summary, the threaded rod 204 is rotated to drive the mounting frame 205 to achieve lifting. The mounting frame 205 is the moving end of the lifting unit 200. The mounting frame 205 drives the unloading unit 300 to extend into the car to achieve unloading, and the threaded rod 204 is placed vertically, which can meet the lifting of large weights.

[0071] Example 4

[0072] Reference Figure 1 - Figure 5, which is a fourth embodiment of the present invention based on the first embodiment, includes a lifting unit 200 including a limiting column arranged on the inner wall of the mounting plate 101, a lifting block slidably arranged on the limiting column, a reciprocating motor arranged at both ends of the limiting column, a transmission wheel arranged at the output end of the reciprocating motor, a transmission belt sleeved on the transmission wheel, and a second mounting frame arranged between two adjacent lifting blocks;

[0074] It should be noted that the lifting unit includes a limiting column fixedly welded to the inner wall of the mounting plate 101, a lifting block is slidably connected to the outer wall of the limiting column, a reciprocating motor is fixedly connected to both ends of the limiting column, a transmission wheel is fixedly connected to the output end of the reciprocating motor, a transmission belt is sleeved on the two transmission wheels, and one side of the transmission belt is fixedly connected to one side of the lifting block, and a second mounting frame is fixedly welded to the inner side of the two lifting blocks.

[0075] When in use, the reciprocating motor is started, and the reciprocating motor drives the transmission wheel to rotate, thereby driving the transmission belt to move on the transmission wheel. When the transmission belt moves, it drives the lifting block to move, thereby driving the second mounting frame to lift.

[0076] In summary, the lifting block is driven to move by the transmission belt, which in turn drives the second mounting frame to be lifted and lowered. The second mounting frame is the moving end of the lifting unit 200. The second mounting frame drives the unloading unit 300 to extend into the car to unload materials. Because the transmission belt needs to bear the weight of the unloading unit 300, compared with the second embodiment, the weight that the transmission belt can bear is less than the weight that the threaded rod 204 can bear. Therefore, the second embodiment is the preferred solution of the present invention.

[0077] A method for using a train unloader comprises the following steps:

[0078] S1, after the carriage enters the station, the moving unit 400 starts and moves the installation unit 100 to the top of the unloading carriage;

[0082] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
