DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] The features of various aspects of the embodiments of the present invention will be described in detail below. In the detailed description below, many specific details are proposed to fully understand the present invention. However, it is obvious to those skilled in the art that the present invention can also be implemented without these specific details. The following description of the embodiments is only for a better understanding of the present invention by illustrating examples of the present invention. The present invention is not limited to any specific settings and methods provided below, but covers all product structures, any improvements, replacements, etc. of methods covered without departing from the spirit of the present invention.

[0035] In the various drawings and the following description, well-known structures and techniques are not shown to avoid unnecessarily obscuring the present invention.

[0036] like Figure 1 As shown, the lifting assembly 4 is installed on the chassis assembly 3, and its front end is hinged to the tray assembly 1, and its rear end is hinged to the chassis assembly 3. The lifting cylinder 34 is installed between the sliding trolley assembly 11 and the auxiliary lifting assembly 2. The tray assembly 1 can adjust the lateral movement and rotation of the hanging object under the manual operation of the operator. When the hanging ear of the hanging object is not aligned with the hook on the hanger, the position of the whole vehicle can be flexibly adjusted through the traction rod assembly 6, and the degree of freedom of the tray assembly 1 can be fine-tuned at the same time, so that the hanging object can be accurately hung or disassembled.

[0037] like Figure 2 As shown, the chassis assembly 3 is mainly composed of a traction rod assembly 6, a front wheel lifting assembly 7, a base frame assembly 8, a pitch adjustment assembly 9, a wheel assembly 10 and other parts. It can realize the functions of walking, steering, pitch adjustment, parking brake and other functions of the bomb hanging vehicle. It is the main load-bearing part of the whole vehicle and provides an installation platform for the lifting assembly 4, the tray assembly 1, the auxiliary lifting assembly 2, and the hydraulic system 5.

[0038] The pitch adjustment assembly 9 is installed at the rear end of the chassis assembly 8 , and the pitch movement of the tray assembly 1 can be mechanically adjusted by adjusting the position of the wheel assembly 10 .

[0039] Two running wheels are installed on both sides of the front wheel lifting assembly 7, bearings are installed inside, and a disc-type steering structure is adopted, which is welded to the front end of the chassis assembly 8; the wheel assembly 10 is hinged at the rear end of the chassis assembly 8, and the traction rod assembly 6 is connected to the front wheel lifting assembly 7. The vehicle steering function can be achieved by traction of the traction rod assembly 6. When the traction rod assembly 6 is lifted, the brake is released and the vehicle can be towed; when the traction rod assembly 6 is placed on the ground in a free state, its brake plate assembly contacts the tire, which plays the role of parking brake.

[0040] like Figure 3 As shown, the lifting assembly 4 is mainly composed of a sliding trolley assembly 11, a lifting arm 12, a support rod 13, an auxiliary support 14, etc., which is used to adjust the mounting height of aircraft suspensions and can adapt to the mounting operations of various types of aircraft suspensions at different mounting positions.

[0041] The lifting assembly 4 is powered by a lifting hydraulic cylinder 34, and can achieve lifting and lowering of the upper surface of the pallet assembly 1 within a height range of 190 mm to 1540 mm. The sliding trolley assembly 11, lifting arm 12, auxiliary support 14 and pallet assembly 1 of the lifting assembly 4 together form a double parallelogram structure, ensuring that the pallet assembly always remains horizontal during the lifting arm's rising and falling process.

[0042] The lifting arm 12 and the supporting rod 13 are important load-bearing parts of the whole vehicle, and the rear parts thereof are connected to the sliding trolley assembly 11 , and the front parts are connected to the pallet assembly 1 , so as to support the pallet assembly 1 .

[0043] One end of the auxiliary support 14 is connected to the middle position of the lifting arm, and the other end is connected to the chassis assembly 3, so that the lifting assembly 4 has better rigidity during the lifting process, thereby improving the safety of the whole vehicle.

[0044] like Figure 4 As shown, the pallet assembly 1 is composed of a pallet frame 15, a transverse locking mechanism 16, a transverse bracket assembly 17, a wire rope isolator 18, a support pin 19, a locking cover device 20, a pallet 21, etc., and is mainly used for bearing various types of suspended objects.

[0045] A flexible steel wire rope vibration isolator 18 is installed under the pallet 21, and the transverse locking mechanism 16 and the transverse bracket assembly 17 are installed on the pallet frame 15. When the weight of the suspended object is relatively light, the weight is less than 300kg, and the suspension object can be adjusted horizontally, 360° rotated, pitched, rolled and other postures, which is convenient for the hanging operation of the suspended object; when the weight of the suspended object is relatively heavy, the weight is greater than 300kg, the flexible steel wire carrier 18 is greatly deformed, and the support column pin 19 enters the hole on the pallet 21 to achieve rigid locking. The pitch and roll adjustment of the pallet assembly 1 can be achieved by adjusting the front wheel lifting assembly 7 and the pitch adjustment assembly 9.

[0046] like Figure 5 As shown, the auxiliary lifting assembly 2 is composed of a connecting shaft 22, an auxiliary support chassis assembly 23, a roller bearing 24, etc. The assembly is hinged on the chassis assembly 3 through the connecting shaft 22. When the tray assembly 1 is in a low position and the upper surface of the tray is ≤720mm from the ground, the roller bearing 24 is supported on both sides of the tray assembly 1 to reduce the force on the lifting assembly 4 and the lifting hydraulic cylinder.

[0047] like Figure 6 As shown, the hydraulic system 5 includes a manual pump 25, an oil pump side combined conduit 26, an oil inlet combined conduit 27, a stop valve assembly 28, an oil return combined conduit 29, a front combined conduit 30, a hose assembly 31, an oil return pipe 32 in the oil tank, an explosion-proof valve 33, and a lifting hydraulic cylinder 34.

[0048] The hydraulic system 5 provides power for the vehicle lifting operation. Turn off the stop valve assembly 28, shake the handle of the manual pump 25, and the hydraulic oil passes through the oil inlet combined conduit 27, the manual pump 25, the oil pump side combined conduit 26, the stop valve assembly 28, the front combined conduit 30, the hose assembly 31, and the explosion-proof valve 33 in sequence, and then enters the rod chamber of the lifting hydraulic cylinder 34, pushing the piston cylinder of the lifting hydraulic cylinder 34 to retract, driving the auxiliary lifting assembly 2 to move, and pushing the tray assembly 1 to lift. When the stop valve assembly 28 is turned off, the position of the lifting assembly 4 can be kept unchanged. Open the stop valve assembly 28, and under the action of its own weight, the hydraulic oil flows back to the oil tank through the explosion-proof valve 33, the hose assembly 31, the front combined conduit 30, the stop valve assembly 28, the oil return combined conduit 29, and the oil return pipe 32 in the oil tank in sequence, and the tray assembly 1 automatically descends.

[0049] In the bomb hanging vehicle of the present invention, when the tray assembly 1 is in a low position, the auxiliary lifting assembly 2 can support the tray assembly 1, thereby improving the safety of the vehicle during operation. Compared with the traditional aircraft low hanging point ground support equipment, the tray assembly 1 can realize manual 360° rotation, lateral movement, flexible rolling, and pitching operations, which is convenient for the hanging operation of the hanging object. When hanging a hanging object of more than 300kg, the chassis assembly 3 can realize pitch adjustment by changing the height front and back, which is convenient for the hanging operation of the hanging object.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should all be covered within the protection scope of the present invention.
