The self-locking universal wheel 11 is a known prior art means that can be easily implemented by those skilled in the art without the need for creative experiments.

Further, a rotating shaft 32 is fixedly connected to the lapping plate 3, the rotating shaft 32 is rotatably connected to the inside of the transfer box 2, a clamping groove 21 is formed in the inner wall of the transfer box 2, an internal hole 33 is formed in the lapping plate 3, a clamping rod 34 is slidably connected to the inside of the internal hole 33, and one end, close to the clamping groove 21, of the clamping rod 34 is arc-shaped;

a spring 35 is fixedly connected inside the built-in hole 33, and one end of the spring 35 close to the clamping rod 34 is fixedly connected with the clamping rod 34;

the lapping plate 3 is rotatably connected in the transfer box 2 through the rotating shaft 32, so when the landing gear support post is required to be installed, the lapping plate 3 is rotated, the clamping rod 34 is separated from the inside of the clamping groove 21 due to the stress of the lapping plate 3, the lapping plate 3 is rotated at the moment, the upper end of the lapping plate is rotated to the outside, the lapping plate 3 is inclined and is in contact with the ground, the landing gear can be pushed to the inside of the transfer box 2 through the sliding groove 31 formed in the lapping plate 3 through the roller on the landing gear support post, and the landing gear support post is fixed through the clamping mechanism in the transfer box 2, so that the landing gear support post can be easily conveyed to the position required to be installed, the landing gear support post is not required to be manually carried by operators, and the labor intensity of the operators is reduced.

Through the spring 35 that sets up, consequently according to the elasticity that spring 35 self possessed for card pole 34 possesses good effect that resets, consequently makes things convenient for its inside of card income draw-in groove 21, and then plays the effect fixed to lapping plate 3, makes its difficult production random rotation, and then ensures the safety of this equipment removal in-process.

Furthermore, the clamping mechanism comprises two clamping plates 22 arranged inside the transfer box 2, one ends of the clamping plates 22 close to the lap plate 3 are arc-shaped, moving rods 26 are fixedly connected to the opposite sides of the clamping plates 22, one ends of the moving rods 26 far away from the clamping plates 22 extend out of the surface of the transfer box 2 and are in sliding connection with the transfer box 2, and one ends of the moving rods 26 extending out of the transfer box 2 are fixedly connected with limiting blocks 25;

a return spring 27 is movably sleeved on the movable rod 26, and two ends of the return spring 27 are respectively and fixedly connected to the clamping plate 22 and the inner wall of the transfer box 2;

one opposite side of each of the two clamping plates 22 is provided with a fixing groove 23 in a wave shape, and the inner wall of each fixing groove 23 is fixedly connected with a sponge pad 24;

when the landing gear strut moves to the inside of the transfer box 2, the landing gear strut contacts with the arc-shaped surface of the clamping plate 22, at this time, the arc-shaped surface of the clamping plate 22 can effectively reduce mechanical blocking of the landing gear strut by the clamping plate 22, so that the landing gear strut can smoothly enter between the two clamping plates 22, at this time, the clamping plate 22 is intervened by the landing gear strut to drive the moving rod 26 to move back and forth, the movement of the clamping plate 22 and the moving rod 26 enables the reset spring 27 to be stressed to compress, at this time, the landing gear strut enters into the inside of the fixed groove 23, and is firmly limited in the inside of the transfer box 2 by the two clamping plates 22 according to the principle that the force is opposite;

through the sponge cushion 24, the abrasion phenomenon of the surface of the landing gear support column caused by the clamping plate 22 can be effectively avoided, and therefore the attractive appearance of the surface of the landing gear support column is ensured.

Furthermore, the number of the clamping mechanisms is multiple, and the clamping mechanisms are vertically arrayed inside the transfer box 2.

Through setting up fixture's quantity into a plurality ofly, when the undercarriage pillar entered into the inside of transfer box 2, fixture can carry out effectual centre gripping to the different positions of undercarriage pillar, consequently ensures the fixed effect to the undercarriage pillar, makes it difficult to produce random phenomenon of rocking.

Furthermore, one end of the rotating rod 12 extends into the bottom plate 1, one end of the rotating rod 12 extending into the bottom plate 1 is fixedly connected with a first bevel gear 13, the interior of the bottom plate 1 is rotatably connected with a threaded rod 14, and a second bevel gear 15 in meshed connection with the first bevel gear 13 is fixedly sleeved on the threaded rod 14;

furthermore, a rectangular moving block 16 is connected to the threaded rod 14 through a thread, the moving block 16 penetrates through the bottom plate 1 and is fixedly connected with the transfer box 2, and the moving block 16 is connected with the bottom plate 1 in a sliding mode.

When the undercarriage pillar moves to the position of required installation, control dwang 12 rotates, and the rotation of dwang 12 drives first bevel gear 13 and second bevel gear 15 and rotates, and second bevel gear 15's rotation drives threaded rod 14 and rotates, and threaded rod 14's rotation makes movable block 16 drive transfer box 2 upwards to move, consequently makes the undercarriage pillar of transfer box 2 inside be close to the position of required installation, and then makes things convenient for operating personnel to fix it.

The working principle is as follows: when the landing gear strut needs to be installed, the lapping plate 3 is rotated, the clamping rod 34 is separated from the inside of the clamping groove 21 under the stress of the lapping plate 3, the lapping plate 3 is rotated at the moment, the upper end of the lapping plate 3 is rotated to the outside, so that the lapping plate 3 is inclined and is in contact with the ground, and the landing gear can be pushed to the inside of the transfer box 2 through the sliding groove 31 formed in the lapping plate 3 through the roller on the landing gear strut;

when the undercarriage pillar moves to the position needing to be installed, the control dwang 12 rotates, the rotation of dwang 12 drives the rotation of the first bevel gear 13 and the second bevel gear 15, the rotation of the second bevel gear 15 drives the threaded rod 14 to rotate, the rotation of the threaded rod 14 enables the moving block 16 to drive the transfer box 2 to move upwards, the undercarriage pillar inside the transfer box 2 is enabled to be close to the position needing to be installed, and then an operator is enabled to fix the undercarriage pillar.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
