[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] refer to Figure 1-Figure 8 The utility model provides a transport corridor with a lifting platform, including a fixed transport platform 1 and a corridor structure 2. The fixed transport platform 1 includes a fixed bracket 3, a first transport platform 4 arranged on the top of the fixed bracket 3, a second transport platform 5 arranged on the fixed bracket 3 at the lower end of the first transport platform 4, a lifting platform 6 and a lifting drive structure. The first transport platform 4 and the second transport platform 5 are provided with upper and lower corresponding through lifting platform areas. A lifting track 7 is provided on the fixed bracket 3 below the lifting platform area of ​​the first transport platform 4, and a lifting frame 8 is provided below the lifting platform 6. The lifting frame 8 is matched in the lifting track 7. The lifting drive structure is arranged on the fixed bracket 3, and the lifting drive structure is connected to the lifting frame 8. The lifting frame 8 is controlled to drive the lifting platform 6 to rise and fall between the lifting platform areas of the first transport platform 4 and the second transport platform 5. The corridor structure is connected to the second transport platform 5.

[0023] When using the transport corridor with a lifting platform provided by the utility model to transport materials for cabin doors at different positions of an aircraft, the transport corridor is moved as a whole to move the fixed transport platform 1 to the cabin door position of the aircraft. The first transport platform 4 and the second transport platform 5 correspond to cabin doors at different heights. When the transport of materials begins at the cabin door at the height of the first transport platform 4, taking the transportation of materials out of the aircraft as an example, the materials are placed on the trolley of the lifting platform 6, and the lifting drive structure is started. The lifting drive structure drives the lifting frame 8 to descend on the lifting track 7 until the lifting platform 6 descends to the lifting platform area position of the second transport platform 5, and the trolley carrying the materials is moved to the second transport platform 5 and transported away through the corridor structure 2.

[0024] As a specific implementation of the lifting drive structure, the lifting drive structure includes a lifting motor 9, a lifting transmission shaft 10 and two lifting chains 11. The two lifting chains 11 are both double-row chains. The lifting motor 9 is arranged below the fixed bracket 3. The lifting transmission shaft 10 is rotatably connected to the lower end of the fixed bracket 3. The output end of the lifting motor 9 is connected to the lifting transmission shaft 10. A lifting driving wheel 12 is respectively provided at both ends of the lifting transmission shaft 10. On the fixed bracket 3 at the uppermost end of the lifting track 7, at the positions corresponding to the two lifting driving wheels 12, a lifting driven wheel 13 is respectively provided. A lifting chain 11 is sleeved on a lifting driving wheel 12 and a lifting driven wheel 13 corresponding to the upper and lower positions. The bottom ends of the lifting frame 8 are fixedly connected to a point on the two lifting chains 11 on both sides.

[0025] During the driving process, the lifting motor 9 drives the lifting transmission shaft 10 to rotate, the lifting transmission shaft 10 drives the lifting driving wheels 12 on both sides thereof to rotate, and the lifting driving wheels 12 drive the lifting chain 11 to rotate. Since a point on the lifting chain 11 is fixedly connected to the lifting frame 8, the lifting chain 11 drives the lifting frame 8 and the lifting platform 6 to lift and lower between the first transport platform 4 and the second transport platform 5.

[0026] In order to tension the chain and ensure the smooth lifting process, as an improvement of the technical solution, a chain tensioning structure is respectively provided at the lower end of the two lifting chains 11, and the chain tensioning structure includes a tensioning bracket 14, a tensioning frame 15, a tensioning wheel 16 and a tensioning spring 17. The tensioning bracket 14 is arranged on the fixed bracket 3 below the lifting chain 11, and the two long sides of the tensioning frame 15 movably pass through the upper ends of two parallel and vertically arranged bracket plates 18 of the tensioning bracket 14, and a tensioning wheel shaft is fixedly connected between the two long sides of the tensioning frame 15 between the two bracket plates 18, and the tensioning wheel 16 is rotatably connected on the tensioning wheel shaft, and the tensioning wheel 16 is against the lifting chain 11, and a tensioning spring 17 is respectively provided on the two long sides of the tensioning frame 15 on the side of a bracket plate 18 away from the tensioning wheel 16, and one end of the tensioning spring 17 is abutted on the short side of the tensioning frame 15, and the other end is abutted on the bracket plate 18.

[0027] During the entire lifting operation, since the tensioning spring 17 is in a compressed setting, the two tensioning springs 17 always push the tensioning frame 15 away from the tensioning bracket 14, thereby pulling the tensioning wheel 16 to always be close to the lifting chain 11, pushing the lifting chain 11, so that the lifting chain 11 always remains in a tensioned state.

[0028] In order to facilitate the installation of the lifting chain 11 and to perform preliminary tensioning during installation, as an improvement of the technical solution, an installation adjustment structure is respectively provided on the fixed bracket 3 at the middle section of the two lifting chains 11, and the installation adjustment structure includes an adjustment fixed bracket 19, an adjustment movable bracket 20, an adjustment wheel 21 and a push rod 22. The adjustment movable bracket 20 is provided with a plurality of long holes. The fixed bracket 3 and the adjustment movable bracket 20 are adjustable by setting adjustment bolts in the long holes. The adjustment movable bracket 20 is rotatably connected to the adjustment wheel 21, and the adjustment wheel 21 engages with the inner ring of the lifting chain 11. The adjustment fixed bracket 19 is fixedly connected to the fixed bracket 3 on one side of the adjustment movable bracket 20, and the push rod 22 is position-adjustable and passes through the upper end of the adjustment fixed bracket 19 and presses on the adjustment wheel 21.

[0029] During installation, in order to facilitate installation, the lifting chain 11 will be installed loosely as a whole. After it is completely put on the lifting active wheel 12 and the lifting driven wheel 13, the adjustment movable bracket 20 is installed on the fixed bracket 3 according to the position of the adjustment wheel 21, so that the lifting chain 11 is in a tensioned state. Since the pressure of the lifting chain 11 on the adjustment wheel 21 is relatively large during the lifting process, in order to prevent the adjustment wheel 21 from driving the adjustment movable bracket 20 to move, the push rod 22 is pushed on the adjustment wheel 21 to support the adjustment wheel 21.

[0030] In order to facilitate the operator to check the overall situation of the equipment, as an improvement of the technical solution, a third transport platform 23 is provided near the bottom end of the fixed bracket 3, and a stair structure 24 is provided between the third transport platform 23 and the second transport platform 5, and between the second transport platform 5 and the first transport platform 4.

[0031] In order to facilitate the movement of equipment, as an improvement, a moving wheel structure 25 is provided under the fixed transport platform 1 and the corridor structure 2.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
