Description

Technical Field

[0001] This invention belongs to the technical field of helicopter bomb box lifting and installation fixture design, and relates to a helicopter bomb box lifting and installation fixture. Background Technology

[0002] Currently, the lifting and installation of helicopter bomb boxes mainly relies on manual labor to lift the bomb boxes and load them into the bomb box compartment along the curved sliding groove. Because the bomb boxes and ammunition are quite heavy, lifting and installing the bomb boxes manually is not only labor-intensive and inefficient, but also inconvenient to handle, making it easy for them to slip and fall, causing the ammunition to drop and creating a great safety hazard. Summary of the Invention

[0003] This application provides a helicopter bomb box lifting and installation fixture, which can solve the problem of low efficiency in lifting and installing bomb boxes.

[0004] Technical solution: A helicopter bomb box lifting and installation fixture, comprising a pulley assembly 1, a bomb box platform 2, a transfer device 3, a lifting platform 4, a first bearing 5, a bracket 6, a hydraulic cylinder 7, a rocker arm 8, a base 9, a second bearing 10, a fixed wheel 11, a reinforcing rib 12, a caster wheel with a brake 13, a hydraulic device 14, a handle 15, a first pulley 16, a first crossbar 17, a second pulley 18, and a second crossbar 19, wherein:

[0005] The pulley assembly 1 is bolted to the cartridge box platform 2; the cartridge box platform 2 is connected to the lifting platform 4 via an adapter 3 and bolted, and the cartridge box platform 2 rotates on the lifting platform 4 via the adapter 3; the upper fixed end of the bracket 6 is connected to the lifting platform 4 via a second crossbar 19 and to the first bearing 5, and the upper movable end of the bracket 6 is connected to the lifting platform 4 via a second pulley 18 to ensure that the bracket 6 pushes the lifting platform 4 up or down; the lower fixed end of the bracket 6 is connected to the base 9 via a first crossbar 17 and to the second bearing 10, and the lower movable end of the bracket 6 is connected to the base 9 via a first pulley 16; the front end of the base 9 is equipped with a pair of fixed wheels 11, and the rear end is equipped with a pair of universal wheels 13 with brakes; the bottom front, middle, and rear parts of the base 9 are each equipped with a reinforcing rib 12; the rear of the base 9 is equipped with a hydraulic device 14 and a handle 15.

[0006] Specifically, a rocker arm 8 is fixed on the first crossbar 17; one end of the hydraulic cylinder 7 is connected to the rocker arm 8, and the other end is connected to the reinforcing rib 12 in the middle of the base 9.

[0007] Specifically, the hydraulic device 14 includes a hydraulic pump with a pedal, a return valve, and a hydraulic oil tank. The hydraulic device 14 is connected to the hydraulic cylinder 7 by a hydraulic hose.

[0008] Specifically, by closing the return valve on the hydraulic device 14 and pressing the hydraulic pump pedal of the hydraulic device 14, the hydraulic pump of the hydraulic device 14 will drive the hydraulic oil through the hydraulic hose from the hydraulic oil tank inside the hydraulic device 14 to the hydraulic cylinder 7 to control its extension; after the hydraulic cylinder 7 extends, it pushes the rocker arm 8 to make the first crossbar 17 rotate, thereby causing the bracket 6 to extend and the lifting platform 4 to rise, so as to achieve the purpose of lifting the shell box platform 2.

[0009] Specifically, by opening the return valve on the hydraulic device 14, hydraulic oil flows through the hydraulic hose from the hydraulic cylinder 7 to the hydraulic oil tank inside the hydraulic device 14; at this time, the hydraulic cylinder 7 shortens, pulling the rocker arm 8 to make the first crossbar 17 rotate, thereby shortening the support 6 and lowering the lifting platform 4 to achieve the purpose of lowering the bomb box platform 2.

[0010] Specifically, the ammunition box platform 2 has an arc-shaped groove adapted to the ammunition box, allowing the ammunition box to slide along the arc-shaped groove.

[0011] Specifically, the ammunition box platform 2 has positioning pin holes that are adapted to the ammunition box, so that the positioning pins on the ammunition box can be inserted into the positioning pin holes of the ammunition box platform 2 to prevent the ammunition box from sliding sideways.

[0012] Specifically, the pulley assembly 1 has 5 pulleys embedded in its upper part, which are adapted to the shape of the bottom of the cartridge box.

[0013] In summary, this application provides a helicopter ammunition box lifting and installation fixture, which effectively solves the problems of difficult installation, high labor intensity, low efficiency, and low safety during helicopter ammunition loading by means of hydraulic lifting and sliding machinery. The invention is simple to operate, highly safe, and can reduce labor intensity and improve work efficiency. Attached Figure Description

[0031] like Figure 3 As shown, the pulley assembly 1 has 5 pulleys embedded in its upper part, which are adapted to the shape of the bottom of the ammunition box.

[0032] like Figures 3 to 4 As shown, the ammunition box platform 2 has a positioning pin hole that matches the ammunition box, so that the positioning pin on the ammunition box can be inserted into the positioning pin hole of the ammunition box platform 2 to prevent the ammunition box from sliding sideways.

[0033] like Figure 5 As shown, by pushing the handle 15, the tooling can be moved as a whole via the fixed wheel 11 and the universal wheel 13 with a braking device.

[0034] like Figure 6 As shown, the ammunition box platform 2 has an arc-shaped groove that matches the ammunition box, allowing the ammunition box to slide along the arc-shaped groove.

[0035] like Figure 7 As shown, the hydraulic device 14 includes a hydraulic pump with a pedal, a return valve, and a hydraulic oil tank. The hydraulic device 14 is connected to the hydraulic cylinder 7 by a hydraulic hose.

[0046] Step 5: Pull the positioning pin of the ammunition box out of the positioning pin hole of the ammunition box platform 2, push the ammunition box along the arc-shaped slide of the ammunition box platform 2, so that the ammunition box slides into the arc-shaped slide inside the helicopter ammunition box compartment.

[0047] Step 6: Move the tooling away from the helicopter by pushing the handle, open the return valve on the hydraulic device 14, and the hydraulic oil flows from the hydraulic cylinder 7 through the hydraulic hose to the hydraulic oil tank in the hydraulic device 14; at this time, the hydraulic cylinder 7 shortens, pulls the rocker arm 8 to make the first crossbar 17 rotate, thereby shortening the bracket 6 and lowering the lifting platform 4 to achieve the purpose of lowering the bomb box platform 2.
