Background

When the airplane is parked or maintained for a long time, the airplane needs to be jacked up by jacking equipment for the airplane, particularly the airplane is disassembled, an extremely stable bracket is needed, and a detachable airplane wing bracket with the patent number of 201520531254.6, which is similar to a fuselage bracket, is found through retrieval and comprises a bracket unit, a lifting unit and a horizontal adjusting unit, wherein the bracket unit comprises an arc-shaped base plate and a U-shaped sliding groove, and the lower part of the arc-shaped base plate is in sliding connection with the U-shaped sliding groove; the lifting unit comprises a supporting rod, a supporting frame, a lifting handle and a connecting rod, the upper end of the supporting rod is connected with the U-shaped sliding groove, the lower end of the supporting rod is provided with external threads and is in threaded connection with the lifting handle, the lower end of the lifting handle is welded with the upper end of the supporting frame, the lower end of the supporting frame consists of four bracket legs, and each bracket leg is uniformly welded on the base; the horizontal adjusting unit comprises leveling handles and a base, the leveling handles are evenly distributed at four corners of the base and are arranged in a rectangular mode, and each leveling handle comprises an internal thread sleeve and a locking device.

The applicant finds that the lower end of the supporting rod of the wing bracket is provided with external threads and is in threaded connection with the lifting handle; the applicant believes that the support rod at the upper end of the wing bracket lacks a guide structure, and the wing bracket can shake when the upper end bears the wing due to the gap between the threads, so that potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a fuselage bracket.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a machine body bracket comprises a base, wherein two ends of the base are fixedly connected through a connecting rod; the central part of the upper end of the base is connected with a screw, and the bottom of the screw is in threaded connection with a rotating handle; a strut is sleeved outside the screw rod and is borne at the upper end of the rotating handle; a cross beam is fixedly connected above the supporting column, and a detachable sleeper is connected in the cross beam; the end part of the base is upwards connected with a plurality of inclined struts, and the tops of the inclined struts are connected through a first fixing sleeve; the fixed sleeve is sleeved on the outer side of the strut; the middle part of the inclined strut is inwards connected with a reinforcing rib which is connected through a second fixing sleeve; the fixed sleeve is sleeved on the outer side of the support.

Furthermore, the first fixing sleeve and the second fixing sleeve are both hollow steel pipes and are connected with the support in a transition fit mode.

Furthermore, the outer side of the upper end of the strut is connected with the bottom of the cross beam in a reinforcing mode through a support rod.

Furthermore, the number of the inclined struts is four, and the inclined struts are uniformly distributed around the support.

Further, an arc-shaped groove is formed above the sleeper, and the radian of the arc-shaped groove is matched with airplane bodies of different models.

Compared with the prior art, the utility model discloses a fuselage bracket is through setting up fixed cover one and fixed cover two respectively on the pillar put on the shelf for the bracket reduces the volume of shaking when bearing the fuselage, has improved the security of fuselage bracket.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

the device comprises a base 1, a base 2, a connecting rod 3, a screw rod 4, a rotating handle 5, a support column 6, a cross beam 7, a sleeper 8, an inclined strut 9, a first fixing sleeve 10, a reinforcing rib 11, a second fixing sleeve 12 and a support rod.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in figure 1, the machine body bracket comprises a cross-shaped base 1 formed by welding 16# channel steel, wherein two ends of the base 1 are fixedly connected through a connecting rod 2; the central part of the upper end of the base 1 is connected with a screw rod 3, and the bottom of the screw rod 2 is in threaded connection with a rotating handle 4; the outer side of the screw rod 3 is sleeved with a support post 5, the support post 5 is borne at the upper end of the rotating handle 4, and the height of the support post 5 can be lifted to a proper position by rotating the rotating handle 4; the upper part of the pillar 5 is fixedly connected with a cross beam 6, the cross beam 6 is made of 20# channel steel, a detachable sleeper 7 is connected in the cross beam 6, an arc-shaped groove is formed in the upper part of the sleeper 7, and the radian of the arc-shaped groove is matched with airplane bodies of different models.

Inclined struts 8 of 50x50x3mm are welded at four ends of the base 1 upwards, and the tops of the inclined struts 8 are connected through a first fixing sleeve 9; the first fixing sleeve 9 is sleeved outside the strut 5; reinforcing ribs 10 of 50x50x3mm are welded inwards in the middle of the inclined strut 8, and the reinforcing ribs 10 are connected through a second fixing sleeve 11; the second fixing sleeve 11 is sleeved outside the strut 5; in this embodiment, fixed cover one 9 and fixed cover two 11 are the hollow steel pipe of external diameter 110mm wall thickness 5mm length 200mm, fixed cover one 9 and fixed cover two 11 all adopt transition fit mode to be connected with pillar 5, adopt and cup joint fixed cover one 9 and fixed cover two 11 in the outside of pillar 5 for pillar 5 remains vertical state throughout in going up and down, when the bracket bears the fuselage, fixed cover one 9 and fixed cover two 11 have been by 8 fixed positions of outside bracing, pillar 5 can't rock in fixed cover one 9 and fixed cover two 11, the security performance of bracket has been improved.
