[0039] The utility model provides a kind of transfer device 10.

[0040] Please refer to Figures 1 to 3In an embodiment of the utility model, this transfer device 10 includes base 100, lifting structure 200, clamping structure 300 and transfer wheel 400, lifting structure 200 is located base 100, lifting structure 200 with clamping structure 300 drive connection, to drive clamping structure 300 moves along up and down direction, clamping structure 300 is equipped with the clamping space 310 for installing the to be transferred object, the width of clamping space 310 is adjustable, transfer wheel 400 is installed in the bottom of base 100.

[0041] The utility model discloses the technical scheme of setting up the clamping structure 300 of adjustable clamping space 310, so that clamping structure 300 can hold the to be transferred object in a certain size range, so as to improve the versatility of transfer device 10, avoid the situation of the to be transferred object of one size corresponding to set up the transfer device 10 of one size. Secondly, lifting structure 200 can drive clamping structure 300 to move along up and down direction, so as to drive the to be transferred object to move along up and down direction, so as to flexibly control the lifting or lowering of the to be transferred object, so as to realize the rapid adjustment of transfer device 10 state.

[0042] In the embodiment, transfer device 10 is applied to aircraft, and the following is described with the application of transfer device 10 to aircraft. When transfer device 10 is applied to aircraft, the to be transferred object is aircraft, and clamping structure 300 is used to hold the skid landing gear 20 of aircraft. Since the clamping space 310 of clamping structure 300 can be adjusted, it can hold the skid landing gear 20 in a certain size range, thereby avoiding the situation of the skid landing gear 20 of one size corresponding to set up the clamping structure 30 of one size, and improving the versatility of transfer device 10. Secondly, since transfer device 10 is connected with skid landing gear 20 through clamping structure 30, the skid landing gear 20 does not need to be specially modified, and transfer device 10 can be connected with the skid landing gear 20 in a certain diameter range, thereby enabling the aircraft to move on the ground through the transfer wheel of transfer device 10, and further meeting the transfer of aircraft. When transfer or attitude adjustment is needed, control lifting structure 200 to move clamping structure 300 upward to make the transfer wheel land and lift the landing gear, so that the overall movement is controlled by the steering wheel. It can be seen that the cooperation of transfer device 10 and skid landing gear 20 can realize the rapid transfer of aircraft and the adjustment of aircraft attitude, that is, the transfer efficiency can be improved, and the transfer cost can be saved.

[0043] It should be noted that the clamping structure 300 of the present scheme is located at the bottom of the base 100. In the present scheme, moving downward means moving the clamping structure 300 away from the base 100. Similarly, moving upward in the present scheme means moving the clamping structure 300 towards the base 100.

[0044] Secondly, the lifting structure 200, the clamping structure 300 and the transfer wheel 400 of the transfer device 10 are independent structures, so that when a certain structure is damaged, the damaged structure can be repaired separately, thereby facilitating maintenance and replacement; and since the lifting structure 200, the clamping structure 300 and the transfer wheel 400 are independent structures, they can be upgraded independently, thereby avoiding the situation that upgrading a certain structure of the lifting structure 200, the clamping structure 300 and the transfer wheel 400 forces the modification of the other two structures.

[0045] It should be noted that the up-down direction can be a vertical direction or a direction slightly inclined to the vertical direction.

[0046] Optionally, the lifting structure 200 is provided with a mounting shaft 210, the clamping structure 300 includes a locking member 320 and two clamping jaws 330 rotatably mounted on the mounting shaft 210 and oppositely arranged, each clamping jaw 330 is provided with a clamping gap on the side facing the other clamping jaw 330 to form a clamping space 310 between the two clamping jaws 330, and the locking member 320 is used to lock the two clamping jaws 330. It can be understood that the two clamping jaws 330 are rotatably mounted on the mounting shaft 210, so that the size of the clamping space 310 between the two clamping jaws 330 can be adjusted by rotating, thereby adapting to the skids of landing gears 20 within a certain diameter range. When the skid of the landing gear 20 is placed in the clamping space 310, the two clamping jaws 330 can be locked by the locking member 320, so that the landing gear 20 is fixed on the clamping jaw 330. Such an installation process is simple and easy to operate, and can improve the connection efficiency of the transfer device 10 and the landing gear 20.

[0047] Specifically, when installing the landing gear 20, the two clamping jaws 330 can be manually rotated in a direction away from each other to increase the clamping space 310, so as to facilitate the placement of the skid of the landing gear 20 in the clamping space 310. When the skid of the landing gear 20 is placed in the clamping space 310, the two clamping jaws 330 can be manually rotated in a direction close to each other, so that the clamping gap of the two clamping jaws 330 contacts the landing gear 20, and then the two clamping jaws 330 are locked by the locking bolt.

[0048] It can be understood that a certain size of clamping jaw 330 cannot adapt to landing gears 20 of all diameters, but can adapt to landing gears 20 within a certain diameter range. The size of the clamping jaw 330 can be selected according to the diameter of the landing gear 20 of different skids.

[0049] Optionally, the locking member 320 comprises a locking bolt, the clamping jaw 330 is provided with a fastening hole between the clamping gap and the rotating hole for the mounting shaft 210, and the locking bolt locks the two clamping jaws 330 through the fastening hole. It can be understood that the fastening hole is arranged between the clamping gap and the rotating hole for the mounting shaft 210, and the two clamping jaws 330 are locked by the locking bolt, which can adjust the gripping degree of the clamping jaw 330, avoid the case that the gripping degree of the clamping jaw 330 is too small, causing unstable installation of the landing gear 20, or the case that the gripping degree of the clamping jaw 330 is too large, damaging the landing gear 20. Moreover, the locking mode of locking the two clamping jaws 330 by the locking bolt is simple in structure and convenient to operate, which can improve the connection efficiency of the landing gear 20 and the clamping structure 300. In addition, such a structure is simple and cheap, which is beneficial to reduce the production cost. Of course, the present solution is not limited to this, and in other embodiments, the locking member 320 can also comprise an electromagnetic lock for locking the two clamping jaws 330.

[0050] Further, in an embodiment of the present solution, the clamping structure 300 is provided along the extension direction of the mounting shaft 210, which can increase the fastening area of the clamping structure 300 and the landing gear 20, thereby improving the connection stability of the transfer device 10 and the landing gear 20. Of course, the present solution is not limited to this, and in other embodiments, the clamping structure 300 can also be provided with only one, and the clamping length of the clamping space 310 of the clamping structure 300 can be increased to increase the fastening area of the clamping structure 300 and the landing gear 20.

The lifting driving member 220 is arranged on the upper side of the base 100, the lifting seat 230 is arranged on the driving end of the lifting driving member 220, the mounting shaft 210 is located below the base 100, and the upper end of the connecting arm 240 is connected to the lifting seat 230 and the lower end is connected to the mounting shaft 210. It can be understood that the driving end of the lifting driving member 220 drives the lifting seat 230 to ascend or descend in the up-down direction, which also drives the mounting shaft 210 to ascend or descend in the up-down direction through the connecting arm 240, thereby realizing the lifting of the clamping structure 300 arranged on the mounting shaft 210 in the up-down direction. Such a lifting structure 200 not only has a simple structure, but also can avoid interference between the lifting structure 200 and the base 100. Of course, the present solution is not limited to this, and in other embodiments, the lifting structure 200 can also comprise a lifting driving member 220 and a U-shaped connecting member. The bending part of the U-shaped connecting member is connected to the driving end of the lifting driving member 220, the mounting shaft 210 is located below the base 100, and the two ends of the U-shaped connecting member are respectively connected to the two ends of the mounting shaft 210.

[0052] Optionally, in an embodiment, the lifting drive 220 is configured as a jack, and it can be understood that the jack is usually made of a solid metal material, such as steel, which makes the jack light and strong in structure. Therefore, using the jack as the lifting drive 220 can ensure the stability and durability of the lifting drive 220, thereby prolonging the service life of the lifting structure 200. Moreover, the jack has a locking function at any height, which can meet the locking function of the landing gear 20 at any height in the stroke, and facilitate the adjustment of the transport attitude of the aircraft. Of course, the present solution is not limited thereto, and in other embodiments, the lifting drive 220 can also be configured as a linear motor.

[0053] It should be noted that the magnitude of the jack can be matched and replaced according to the weight of the aircraft, thereby improving the applicability of the transfer device 10.

[0054] In the present embodiment, the lifting drive 220 is configured as a hydraulic jack, which has strong jack-up capacity and can ensure the stability when supporting the aircraft. Moreover, the hydraulic jack has double insurance functions, such as safety locking and automatic unloading mechanism, which can effectively prevent accidental sliding and ensure the stability of the aircraft. At the same time, the hydraulic jack is made of high-strength material and hydraulic oil, which ensures the high stability and long service life of the lifting drive 220, and is not easy to leak and damage, with high reliability.

[0055] The jack is fixedly connected with the lifting seat 230 through the bottom plate connecting block, which can reduce the difficulty of connecting the lifting seat 230 with the driving end of the jack.

[0056] Further, the opposite sides of the lifting seat 230 are each connected with the two ends of the mounting shaft 210 one by one through at least one connecting arm 240, which can ensure the stability of the mounting shaft 210 running in the up-down direction, thereby increasing the stability of the landing gear 20 running in the up-down direction.

[0057] Optionally, in an embodiment of the present solution, the base 100 is further provided with a guide rail 110 extending in the up-down direction, and the lifting seat 230 is slidingly connected with the guide rail 110. It can be understood that the guide rail 110 guides the lifting seat 230 to move in the up-down direction, which can improve the stability of the lifting seat 230 moving, thereby improving the stability of the clamping structure 300 moving, and further realizing the stability of the landing gear 20 moving. Of course, the present solution is not limited thereto, and in other embodiments, the base 100 can also be provided with a guide rod extending in the up-down direction, and the lifting seat 230 is provided with a guide cylinder corresponding to the guide rod, and the guide rod is slidingly arranged in the guide cylinder, thereby guiding the movement of the lifting seat 230 by the guide rod and the guide cylinder.

[0058] Further, the guide rails 110 are arranged at intervals in the circumferential direction of the lifting seat 230, so that each part in the circumferential direction of the lifting seat 230 can be synchronously moved in the up-down direction, avoiding the inclination of the lifting seat 230, and the inclination of the mounting shaft 210, and the inclination of the landing gear 20.

[0059] In the embodiment, the guide rails 110 are arranged at intervals in the circumferential direction of the lifting seat 230, and the number of the guide rails 110 is not limited to four, and in other embodiments, the number of the guide rails 110 can be six.

[0060] In the embodiment, the sliding block 120 is slidably connected to the guide rail 110, and the lifting seat 230 is connected to the sliding block 120. It can be understood that the sliding block can improve the smoothness of the movement of the lifting seat 230. Of course, the present solution is not limited to this, and in other embodiments, the lifting seat 230 can be provided with a sliding rib corresponding to the guide rail 110, and the sliding rib is slidably arranged on the guide rail 110.

[0061] Optionally, the base 100 is provided with a support 130 and a limiting piece 140 arranged at the upper end of the support 130, and at least part of the limiting piece 140 is located on the rising path of the lifting seat 230, so that the lifting seat 230 is stopped. It can be understood that the limiting piece 140 can limit the highest rising displacement of the lifting seat 230, thereby limiting the movement of the lifting structure 200, avoiding the running height of the lifting structure 200 being too high, and thereby avoiding the long time consumption when the lifting structure 200 runs downward to lower the landing gear 20 to the position.

[0062] Further, the support 130 is configured as a support gusset, and one side edge of the support gusset is connected to the base 100. It can be understood that the support 130 configured as a support gusset can improve the stability by using a triangular configuration. Of course, the present solution is not limited to this, and in other embodiments, the support 130 can also be configured as a common rectangular support plate.

[0063] In the embodiment, the side edge of the support gusset is provided with a reinforcing flange. It can be understood that the reinforcing flange arranged at the side edge of the support gusset can improve the strength of the support gusset, thereby increasing the stability of the support 130. In the present solution, the support gusset is connected to the base through the reinforcing flange, so that the connecting area and the supporting area of the support gusset are increased, thereby facilitating the installation operation of the support gusset and improving the stability of the support gusset. Of course, the present solution is not limited to this, and in other embodiments, the reinforcing flange can not be arranged at the side edge of the support gusset.

Specifically, the arrangement of the plurality of support members 130 at intervals can improve the supporting force of the support members 130 on the limiting members 140, and the arrangement of the limiting members 140 in the form of a limiting frame can ensure the limiting ability of the limiting members 140 on the lifting seat 230 while reducing the weight of the limiting members 140.

[0065] The guide rail 110 is connected to the support angle plate.

[0066] Further, the transfer wheel 400 is fixedly connected to the bottom plate, and one of the two sides of the clamping structure 300 is provided with the transfer wheel 400. When the lifting structure 200 performs the jacking movement, the landing gear 20 is jacked up, and the transfer wheel 400 touches the ground, gradually jacking up the landing gear 20 and the aircraft, so as to transfer or adjust the attitude of the aircraft by using the transfer wheel 400.

Thus, the transfer device 10 can not only realize the transfer of the aircraft with the skid landing gear 20, but also can be used in combination with other devices that need to be transferred as a whole. The plurality of transfer devices 10 can be connected by the connecting member 150 to form a transfer trolley for carrying work, which can save the carrying cost and improve the carrying efficiency.
