Detailed Description

Referring to fig. 1-3, an aircraft body bracket, a support frame 1 and a profiling bracket 2, wherein the bottom of the support frame 1 is provided with casters 5, the top of the support frame 1 is provided with a lifting mechanism 3 for driving the profiling bracket 2 to lift, and those skilled in the art will understand that the above is prior art, and in practical application, the support frame 1 can be welded into a frame structure meeting requirements through pipe fittings; the profiling bracket 2 generally comprises a bracket 201 and a supporting block 202, wherein the supporting surface of the supporting block 202 is formed according to the profiling of the aircraft fuselage, and the supporting block 202 is connected with the bracket 201 through screws so as to replace the supporting block 202 with a different shape according to different types of aircraft.

The lifting mechanism 3 may be an existing screw lifting mechanism 3, for example, the lifting mechanism 3 includes a lifting screw 301 and a lifting nut seat 302, the lifting nut seat 302 is rotationally connected with the support frame 1, the lifting screw 301 is in threaded fit with the lifting nut seat 302, the top end of the lifting screw 301 is connected with the bracket 201, and the lifting nut seat 302 is fixedly connected with a turntable 303, so that the lifting nut seat 302 is driven to rotate by the turntable 303, and the lifting screw 301 is driven to lift.

The utility model is further improved on the basis of the prior art to solve the defect that the prior art is difficult to well support the machine body on the inclined ground, in particular, on the basis, a plurality of support mechanisms 4 are arranged on the support, the support mechanisms 4 play a role in supporting the whole bracket and the machine body, and the support frame 1 of the embodiment is provided with four support frames which are respectively arranged at four corners of the support frame 1 so as to form stable support. It is to be understood that in other embodiments of the present utility model, the number of the supporting mechanisms 4 may be three, and the connection lines of the three supporting mechanisms 4 may form a triangle, or five or more.

The supporting mechanism 4 comprises an adjusting screw 401 and a supporting seat 402, the adjusting screw 401 is in threaded fit with the supporting frame 1, specifically, a mounting plate 403 is arranged on the supporting frame 1 corresponding to each supporting mechanism 4, the adjusting screw is in threaded fit with a supporting nut seat 404, the mounting plate 403 can be welded or fixed with the supporting frame 1 in other modes, a supporting nut seat 404 is arranged on the mounting plate 403, and the supporting nut seat 404 can be connected with the mounting plate 403 through screws.
