[0023] And in the above manner, in order to form a fall protection for the lifted container, a same bidirectional screw two 11 is rotatably installed on both sides of the connecting bracket two 2, and a driving motor three is fixedly installed on the top of the connecting bracket two 3, the output shaft of the driving motor three and the bidirectional screw two 11 are both fixedly sleeved with a gear, the two gears are engaged, the bidirectional screw two 11 is threadedly installed with two link strips 12, the two link strips 12 are both fixedly installed with a horizontal push plate 13 on the side close to each other, the two horizontal push plates 13 are respectively penetrated through the two sides of the connecting bracket two 3 and are respectively slidably connected with the two sides of the connecting bracket two 3, the bottom of the two horizontal push plates 13 are both fixedly installed with a hydraulic cylinder 14, the output shaft of the two hydraulic cylinders 14 are respectively penetrated through the two horizontal push plates 13 and are slidably connected with the corresponding horizontal push plate 13, the output shaft of the two hydraulic cylinders 14 are both fixedly installed with an anti-falling plate 15, the top of the two anti-falling plates 15 are both provided with an anti-falling groove 16, and the side close to each other of the two anti-falling grooves 16 is provided as an opening.

[0024] In the present manner, in order to reduce the bearing force of the horizontal moving screw 18, two slide rails are fixedly installed on the top of the gantry 1, the two slide rails are both slidably installed with a sliding block, the top of the two sliding blocks are both fixedly connected with the middle connecting plate 20, and a guide slide is formed on the top of the gantry 1, the connecting column 21 is penetrated through the guide slide and is in contact with the inner wall of the guide slide, so that the connecting column 21 can be provided with sufficient activity space.

[0025] The working principle of the railway freight container lifting appliance is as follows:

[0026] When the container needs to be lifted, the driving motor one is first started in the forward direction, the output shaft of the driving motor one drives the horizontal moving screw 18 to rotate, the sliding plate 19 moves horizontally with the connecting column 21, so that the connecting bracket one 2 and the clamp 7 can move horizontally as a whole, until the clamp 7 moves to the top of the container, the driving motor one is turned off, then the driving motor two is started in the forward direction, the output shaft of the driving motor two drives the winding roller 5 to rotate, the lifting rope 6 is released, until the clamp 7 is lowered to the top of the container, the clamp 7 and the container can be fixed;

[0027] After being fixed, the driving motor two is started reversely to start winding the lifting rope 6, and the container is lifted by the lifting rope 6 until the clamp 7 is lifted to the final position, then the driving motor two is turned off, and the driving motor four is started positively, the output shaft of the driving motor four drives the bidirectional screw rod one 9 to rotate, and the two stable clamping pieces 10 are moved to each other through the thread relationship between the bidirectional screw rod one 9 and the stable clamping piece 10, and finally the two stable clamping pieces 10 contact the two sides of the container respectively to form clamping action, then the driving motor three is started positively, the bidirectional screw rod two 11 is rotated through the meshing of the two gears, and the two connection strips 12 are moved to each other through the thread cooperation with the connection strip 12 to push the two horizontal push plates 13 to move until the connection strip 12 contacts one side of the connecting support two 3, and the driving motor three is turned off, at this time, the two anti-falling supporting plates 15 are located below the container;

[0028] Then, the driving motor one is started to drive the connecting support one 2 and the container to move, and the container does not shake during the moving process, and even if the lifting rope 6 is broken, the anti-falling supporting plate 15 and the anti-falling groove 16 below can support the container;

[0029] Until the container moves to the top of the flat car on the train, the driving motor three is started reversely to move the anti-falling supporting plate 15 away from the bottom of the container, and then the driving motor two is started positively to release the lifting rope 6, and the container is placed on the flat car.

[0030] Compared with the related art, the railway freight container lifting appliance has the following beneficial effects:

[0031] The railway freight container lifting appliance can clamp the two sides of the container through the stable clamping piece 10 when the container is lifted, so that the container can be prevented from shaking, and the anti-falling supporting plate 15 provided below the container can form a protection for the container, so that the container can be prevented from falling to the ground even if the lifting rope 6 is broken or the container is separated from the clamp 7, and the container and the surrounding staff can be protected.

[0032] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion or direct or indirect application in other related technical fields is included in the patent protection range of the utility model.
