Description

Technical Field

[0001] The invention relates to a three-dimensionally adjustable aircraft engine transfer vehicle, belonging to the technical field of aircraft engines. Background Art

[0002] The manufacturing, testing, use and maintenance of aircraft engines involve transportation needs in various occasions. Engine transport vehicles have been widely used as essential tools for short-distance engine turnover on flat ground.

[0003] The existing engine transfer device (see Chinese patent publication number CN220391872U) is a fixed design, which has the problem that it cannot be changed and adjusted to be compatible with the aircraft engine for transfer. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a three-dimensionally adjustable aircraft engine transport vehicle.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a three-dimensionally adjustable aircraft engine transport vehicle, comprising:

[0007] A transfer vehicle is provided which can adjust the load-bearing pins in three degrees of freedom, vertically, longitudinally and transversely, so as to be compatible with and installed on aircraft engines.

[0008] The transfer vehicle comprises: a support frame with a load-bearing pin installed on the top, the support frames are four spaced apart and can be lifted vertically;

[0009] It also includes a chassis that can be adjusted laterally, and the four support frames are installed on the chassis in pairs and can be adjusted longitudinally;

[0010] Also included is a telescopic armrest that controls longitudinal adjustment of the ipsilateral support frame.

[0011] The chassis shown includes transverse screw sleeves distributed at rectangular intervals, two longitudinal transverse screw sleeves are fixedly connected by two longitudinal guide rail rectangular beams at intervals, and the longitudinal guide rail rectangular beams are spaced to form a track;

[0012] The two horizontal transverse screw sleeves are screwed together by a transverse adjusting screw, and the threads at both ends of the transverse adjusting screw rotate in opposite directions. When the transverse adjusting screw rotates, the transverse spacing between the two horizontal transverse screw sleeves can be adjusted to achieve transverse adjustment of the chassis itself; a transverse locking nut is screwed on the transverse adjusting screw, and when the transverse locking nut is screwed on the transverse adjusting screw and presses against the transverse screw sleeve, transverse adjustment can no longer be performed.

[0013] A tool box mounting seat for connecting a tool box is fixed in the middle of the two longitudinal guide rail rectangular beams.

[0014] The transverse screw sleeve on the inner side of the chassis is fixedly connected with the longitudinal guide rail rectangular beam by reinforcing ribs for reinforcement; a wheel mounting seat is fixed at the bottom of the transverse screw sleeve and the longitudinal guide rail rectangular beam, and a bidirectional braking caster is installed on the wheel mounting seat, and the bidirectional braking caster is distributed and installed on four wheel mounting seats at the four feet of the chassis.

[0015] The support frame comprises a lower load-bearing screw sleeve slidably mounted with the longitudinal guide rail rectangular beam of the chassis, and a support frame fixing plate with which the lower load-bearing screw sleeve is controllably screwed by bolts and nuts;

[0016] The upper bearing screw sleeve is spaced above the lower bearing screw sleeve, and the lower bearing screw sleeve and the upper bearing screw sleeve are screwed together through a vertical adjustment screw. The threads at both ends of the vertical adjustment screw have opposite rotation directions. The vertical adjustment screw is rotated to adjust the vertical lifting distance between the lower bearing screw sleeve and the upper bearing screw sleeve, so as to realize the vertical lifting function of the support frame itself.

[0017] A vertical locking nut is screwed onto the vertical adjusting screw rod; and a quick-release clamp A for clamping the load-bearing pin is installed on the upper load-bearing screw sleeve.

[0018] The telescopic handrail comprises two telescopic handrail screw sleeves which are spaced apart from each other, and quick-release clamps B are fixed at both ends of the telescopic handrail screw sleeves, and the quick-release clamps B are clamped on the upper load-bearing screw sleeves of the support frame;

[0019] The telescopic handrail also includes a telescopic handrail adjusting screw that is screwed together with the middle parts of the two telescopic handrail screw sleeves. The threads at both ends of the telescopic handrail adjusting screw are screwed in opposite directions. The telescopic handrail adjusting screw is rotated to adjust the telescopic movement of the two telescopic handrail screw sleeves. A telescopic handrail locking nut is screwed together with the telescopic handrail adjusting screw.

[0020] The beneficial effects of the present invention are as follows: the support frame with the load-bearing pins installed on the top can be adjusted vertically, the support frames on the same side can be adjusted longitudinally on the chassis, and the support frames on the opposite side can be adjusted laterally through the chassis, so that the four load-bearing pins can be changed and adjusted with three degrees of freedom in the vertical, longitudinal and transverse directions to adapt and install with the aircraft engine, thus solving the problem that the fixed-design engine transfer device cannot be changed and adjusted to adapt and install with the aircraft engine for transfer.

[0029] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0030] like Figures 1 to 5 shown.

[0031] A three-dimensionally adjustable aircraft engine transport vehicle of the present application comprises:

[0032] A support frame 3 with a load-bearing pin 31 is installed on the top, and the support frame 3 can be raised and lowered vertically; the support frames 3 are four and spaced apart, and four load-bearing pins 31 are installed on the tops of the corresponding four support frames 3. The load-bearing pins 31 serve as connecting parts to be load-bearingly connected to the aircraft engine.

[0033] It also includes a chassis 1 which can be adjusted laterally. The four support frames 3 are installed on the chassis 1 in pairs and can be adjusted longitudinally.

[0034] According to the position where the aircraft engine interface needs to be installed, the support frame 3 itself is adjusted vertically, the support frames 3 on the same side are adjusted longitudinally on the chassis 1, and the support frames 3 on the opposite side are adjusted laterally through the chassis 1, so that the four load-bearing pins 31 after installation are adjusted in three degrees of freedom, vertically, longitudinally, and laterally, to adapt and install with the aircraft engine, solving the problem that the fixed-design engine transport device cannot be adjusted to adapt and install with the aircraft engine for transportation. After the aircraft engine is connected to the transport vehicle through the load-bearing pins 31, it is then rolled and transported through the two-way brake casters 4 at the four feet at the bottom of the chassis 1.

[0035] The chassis 1 shown includes transverse screw sleeves 11 distributed at rectangular intervals, two longitudinal transverse screw sleeves 11 are fixedly connected by two longitudinal guide rail rectangular beams 6 at intervals, and the longitudinal guide rail rectangular beams 6 are spaced to form a track;

[0036] The two lateral transverse screw sleeves 11 are screwed together by a transverse adjustment screw 9, and the threads at both ends of the transverse adjustment screw 9 have opposite rotation directions. When the transverse adjustment screw 9 rotates, the lateral spacing between the two lateral transverse screw sleeves 11 can be adjusted to achieve lateral adjustment of the chassis 1 itself; a transverse locking nut 10 is screwed on the transverse adjustment screw 9, and when the transverse locking nut 10 is screwed on the transverse adjustment screw 9 and presses against the transverse screw sleeve 11, lateral adjustment can no longer be performed.

[0037] The middle part of the two longitudinal guide rail rectangular beams 6 welding A tool box mounting seat 7 for connecting a tool box is fixed, and the tool box mounting seat 7 strengthens the middle interval between the two longitudinal guide rail rectangular beams 6.

[0038] The transverse screw sleeve 11 on the inner side of the chassis 1 is fixedly connected to the longitudinal guide rail rectangular beam 6 by reinforcing ribs 8 for reinforcement. A wheel mounting seat 5 is fixed to the bottom of the transverse screw sleeve 11 and the longitudinal guide rail rectangular beam 6, and a two-way brake caster 4 is installed on the wheel mounting seat 5. The two-way brake caster 4 is four wheel mounting seats 5 distributed and installed on the four feet of the chassis 1.

[0039] The support frame 3 includes a lower load-bearing screw sleeve 12 which can be slidably installed with the longitudinal guide rail rectangular beam 6 of the chassis 1, and a support frame fixing plate 30 with which the lower load-bearing screw sleeve 12 can be controllably screwed together through bolts and nuts. The support frame fixing plate 30 contacts the bottom surface of the longitudinal guide rail rectangular beam 6 of the chassis 1, and the bolts pass through the lower load-bearing screw sleeve 12 and screw the nuts into the support frame fixing plate 30; when the bolts and nuts are loosened, the lower load-bearing screw sleeve 12 can slide on the longitudinal guide rail rectangular beam 6, and when the bolts and nuts are tightened, the lower load-bearing screw sleeve 12 and the support frame fixing plate 30 are clamped on the longitudinal guide rail rectangular beam 6 in opposite directions and cannot slide.

[0040] The support frame 3 also includes an upper bearing screw sleeve 15 spaced above the lower bearing screw sleeve 12. The lower bearing screw sleeve 12 and the upper bearing screw sleeve 15 are screwed together through a vertical adjustment screw 14. The threads at both ends of the vertical adjustment screw 14 are screwed in opposite directions. The vertical adjustment screw 14 is rotated to adjust the vertical lifting distance between the lower bearing screw sleeve 12 and the upper bearing screw sleeve 15, so that the support frame 3 itself can be lifted and lowered vertically; a vertical locking nut 13 is screwed on the vertical adjustment screw 14. When the vertical locking nut 13 is screwed against the lower bearing screw sleeve 12 and the upper bearing screw sleeve 15, the vertical adjustment screw 14 can no longer be adjusted for vertical lifting; a quick-release clamp A16 for clamping the bearing pin 31 is installed on the upper bearing screw sleeve 15; the quick-release clamps A16 on the top of the four support frames 3 are clamped correspondingly to the four bearing pins 31. One flap of the quick-release clamp A16 is fixed to the top of the upper load-bearing screw sleeve 15 of the support frame 3 , and the other flap of the quick-release clamp A16 can be relatively expanded outward to install the load-bearing pin 31 or retracted inward to clamp the load-bearing pin 31 .

[0041] It also includes a telescopic armrest 2 for longitudinal adjustment of the support frame 3 on the same side. There are two telescopic armrests 2. The two telescopic armrests 2 fix the distance between the support frame 3 on the same side after the longitudinal adjustment is completed. The telescopic armrest 2 can also be extended and retracted to adjust the longitudinal adjustment of the support frame 3 on the same side on the chassis 1.

[0042] The telescopic handrail 2 includes two telescopic handrail screw sleeves 27 that are spaced apart. Quick-release clamps B26 are fixed at both ends of the telescopic handrail screw sleeves 27. The quick-release clamps B26 are clamped on the upper load-bearing screw sleeves 15 of the support frame 3.

[0043] The telescopic handrail 2 also includes a telescopic handrail adjusting screw 29 which is screwed together with the middle parts of the two telescopic handrail screw sleeves 27. The threads at both ends of the telescopic handrail adjusting screw 29 are screwed in opposite directions. The telescopic handrail adjusting screw 29 is rotated to adjust the two telescopic handrail screw sleeves 27 for telescopic adjustment. A telescopic handrail locking nut 28 is screwed together with the telescopic handrail adjusting screw 29. When the telescopic handrail locking nut 28 is screwed together with the telescopic handrail adjusting screw 29 to resist the telescopic handrail screw sleeves 27, the telescopic handrail adjusting screw 29 can no longer be screwed together with the telescopic handrail screw sleeve 27 for limiting the position to achieve telescopic adjustment.
