The recyclable packaging equipment for the secondary skeleton inside the rail vehicle comprises: a frame assembly 1;

[0028] Two one-layer telescopic bracket assemblies 2, both of which are arranged on the frame assembly 1, the one-layer telescopic bracket assembly 2 includes a T-tube, two slide grooves 3, a telescopic frame 4, a plurality of limiting circular tubes 5 and a plurality of nylon sliders 6, the two slide grooves 3 are both opened on the T-tube, the telescopic frame 4 is arranged on the T-tube, the telescopic frame 4 is adapted to the two slide grooves 3, the plurality of limiting circular tubes 5 are arranged on the telescopic frame 4, the plurality of nylon sliders 6 are arranged on the telescopic frame 4, the plurality of nylon sliders 6 correspond to the plurality of limiting circular tubes 5 respectively, and the telescopic frame 4 is connected to the T-tube through a plurality of locking pins 7;

[0029] Two groups of first polyurethane blocks 8 are both arranged on the frame assembly 1 , and the number of the first polyurethane blocks 8 in each group is two. The two first polyurethane blocks 8 are respectively located on both sides of a layer of telescopic bracket assembly 2 .

[0030] The function of the two slide grooves 3 is to provide the limiting circular tube 5 for adjusting the spacing, the function of the locking pin 7 is to fix the position of the limiting circular tube 5, and the function of the nylon slider 6 is to enable the limiting circular tube 5 to slide smoothly when adjusting the position of the limiting circular tube 5.

[0031] The outer layer of the limiting circular tube 5 is wrapped with rubber-plastic heat-insulating cotton, so that it can absorb the impact force caused by the bumping of the package, thereby preventing bumps when clamping the product.

[0032] The frame assembly 1 is provided with a second-layer turnover assembly 9 , and the second-layer turnover assembly 9 is connected to the frame assembly 1 via two rotating shafts 12 .

[0033] The second-layer flip assembly 9 is provided with a second-layer telescopic bracket assembly 10 , and the second-layer telescopic bracket assembly 10 has the same structure as the first-layer telescopic bracket assembly 2 . The second-layer flip assembly 9 is provided with two groups of second polyurethane blocks 11 .

[0034] The number of the second polyurethane blocks 11 in each group is two, and the two second polyurethane blocks 11 are respectively located on both sides of the two-layer telescopic bracket assembly 10 .

[0035] The second-layer turnover assembly 9 is provided with two latches 13, both of which are adapted to the frame assembly 1. The frame assembly 1 is provided with four stacking ankles 14, which are distributed in a rectangular array.

[0036] The four stacking ankles 14 are each provided with a protective foot pad 15 , the frame assembly 1 is provided with four fork sleeves 16 , the four fork sleeves 16 are distributed in a rectangular array, and the four fork sleeves 16 correspond to each other in pairs, and the frame assembly 1 is provided with two gas springs 17 , and the gas springs 17 are connected to the second-layer flip assembly 9 .

[0037] The function of the stacking ankle 14 is that when two packaging boxes are stacked, the steel pipes at the four corners of the top of the packaging can be inserted into the ankle grooves at the four corners of the bottom of the upper packaging box to achieve stable stacking of multiple layers of packaging. The function of the fork sleeve 16 is to allow the fork of the forklift to be placed in the fork sleeve 16 during forklift transportation to prevent the packaging box and the fork from sliding relative to each other and tipping over. The protective foot pad 15 is made of polyurethane and its main function is to support the bottom of the center pin box. The first polyurethane block 8 and the second polyurethane block 11 function to prevent the placed products from bumping and scratching the paint.

[0038] The main body of the frame assembly 1 is made of welded steel pipes. The functions of the first-layer telescopic bracket assembly 2 and the second-layer telescopic bracket assembly 10 are to adjust the position of the limiting circular tube 5 so that it can meet the clamping limit of each product. The main body of the first-layer telescopic bracket assembly 2 is made of steel pipes and circular tubes, and the main body of the second-layer flip assembly 9 is made of welded steel pipes.

[0039] The double-layer stacking is designed to enable the packaging box to adapt to the secondary frames of different cross-sections, increase the packaging loading capacity, increase the versatility of packaging loading, and reduce the transportation cost. The secondary frame packaging flipping sequence is: first open the latch 13, then flip the second-layer flip assembly 9 around the rotating shaft 12, and automatically stop through the gas springs 17 on both sides;

[0040] The working principle of the recyclable packaging equipment for secondary skeletons installed in rail vehicles provided by the present invention is as follows:

[0041] Step 1: First, flip the second-layer flip assembly 9 from the initial state, put the product into the first-layer packaging rack, make it contact with the first polyurethane block 8 plane, and complete the limit position under the clamping of the adjacent limit round tubes 5 in the first-layer telescopic bracket assembly 2, then fix the position of the first-layer telescopic bracket assembly 2 with the locking pin 7, and then put the product into the first-layer telescopic bracket assembly 2 in turn. After loading is completed, put down the second-layer flip assembly 9 and fix it with the latch 13, repeat the above-mentioned first-layer loading operation, adjust and fix the second-layer telescopic bracket assembly 10, put the product in turn, and finally complete the packaging loading;

[0042] The second step: the position of the telescopic bracket assembly can be adjusted to meet the packaging of the secondary skeleton of different rail vehicle models. The telescopic bracket assembly can be adjusted to be compatible with the secondary skeleton shape and length and width changes within a certain range. In addition, the packaging box has the function of double-layer stacking, which can greatly increase the packaging loading capacity.
