DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 creative work are within the scope of protection of the present invention.

[0024] Example 1: A mobile deceleration parachute installation ladder, such as Figure 1 As shown, it includes a mobile device 1 that can move on the ground. The mobile device 1 in this embodiment is a ground tank. In other embodiments, the mobile device 1 can also be an AGV cart.

[0025] The top of the mobile device 1 is fixed with an electric rotating platform ( Figure 1 The electric rotating platform in this embodiment includes a rotating drive motor installed in the mobile device 1. The output shaft of the rotating drive motor rotates through the top of the mobile device 1 and is fixedly connected to the rotating platform. The rotating platform adopts a circular plate structure and is rotatably arranged on the top of the mobile device 1.

[0026] A lifting device is fixed on the top of the rotating platform ( Figure 1 The lifting device in this embodiment adopts a hydraulic cylinder, the top of the lifting device is fixedly connected to the bottom of the support frame 2, and the hydraulic cylinder is used to fine-tune the height of the support frame 2.

[0027] Two first upright poles 4 are fixedly provided on both sides of the support base frame 2, and a second layer support beam 7 extending in the front-to-back direction is fixedly connected to the middle between the two front-to-back corresponding first upright poles 4 on the left and right sides.

[0028] A standing platform is provided on top of the support frame 2. This platform comprises multiple platforms stacked in a sequence from bottom to top, with the upper platform area smaller than the lower platform area, forming a multi-layered, stepped structure. Specifically, in this embodiment, the standing platform comprises, from bottom to top, a first-level platform 3, a second-level platform 8, and a third-level platform 10. The first-level platform 3 is fixed flat on top of the support frame 2.

[0029] The left and right ends of the second-level platform 8 are fixed on the second-level support beam 7. The front and rear width of the second-level platform 8 is smaller than the front and rear width of the first-level platform 3, and the front and rear ends of the second-level platform 8 are located between the front and rear ends of the first-level platform 3, so that when the folded deceleration parachute is stored, the middle part of the deceleration parachute is overlapped on the second-level platform 8, and the edges of the deceleration parachute hang from the front and rear sides of the second-level platform 8 onto the first-level platform 3.

[0030] In order to prevent the parachute from falling on the edge of the first platform 3 and sliding from the front and rear ends of the first platform 3 to the ground, Figure 1 As shown, in this embodiment 1, vertical baffles 5 extending in the left-right direction are fixed to the tops of the front and rear ends of the support frame 2, and the first platform 3 is located between the two baffles 5. The top of the baffle 5 is lower than the top of the second platform 8 to facilitate the operator to cross over.

[0031] The third-level platform 10 is fixed on the top of the third-level bracket 9, and the third-level bracket 9 is fixed on the top right side of the second-level platform 8. The right end of the third-level platform 10 extends to be flush with the front and rear of the left side of the first upright pole 4 on the right.

[0032] In order to prevent the operator from slipping when standing on the third-level platform 10, in this embodiment, an anti-skid pad layer 11 is fixedly provided on the top of the third-level platform 10. The anti-skid pad layer 11 is a rubber pad with anti-skid patterns on the surface.

[0033] The tops of the first uprights 4 on both sides are fixed with fireproof and heat-insulating lifting devices extending in the front-to-back direction. The fireproof and heat-insulating lifting devices can be extended upward or retracted downward, and when the fireproof and heat-insulating lifting devices are extended upward to the maximum height, their tops are higher than the top of the standing platform. Specifically, Figure 2 As shown, the fireproof and heat-insulating lifting device in this embodiment includes a heat-resistant equipment box 13 fixed on the top of two corresponding first vertical poles 4 in the front and rear. The heat-resistant equipment box 13 is an upper open structure, and a first slide rail 15 extending along the front and rear direction is fixed in the heat-resistant equipment box 13.

[0034] like Figure 3 As shown, a first sliding groove 1501 with an upper opening is defined in the first sliding rail 15 , and limiting grooves 1502 are defined on both left and right side walls of the first sliding groove 1501 .

[0035] Two scissor-type lifting rods 17 are arranged at intervals in the front and rear directions in the heat-resistant equipment box 13. The scissor-type lifting rod 17 includes an X-shaped rod hingedly connected up and down. The X-shaped rod is a retractable scissor-type hinged rod structure. One of the two lower ends of the scissor-type lifting rod 17 is hingedly connected to the first slide rail 15, and the other end of the two lower ends of the scissor-type lifting rod 17 is hingedly connected to the top of the first sliding seat 16.

[0036] The first sliding seat 16 is slidably arranged in the first sliding groove 1501. The left and right side walls of the first sliding seat 16 are fixed with anti-slip plates, which are slidably inserted in the limiting groove 1502. The two first sliding seats 16 are located inside between the front and rear scissor lift rods 17.

[0037] A cover 14 is located above the scissor lift 17. Cover 14 closes the upper opening of the heat-insulating device housing 13. A second slide rail 18 is fixedly mounted at the bottom of cover 14. Two second slide seats are slidably mounted at the bottom of second slide rail 18. The sliding connection structure between second slide rail 18 and second slide seats is identical to that between first slide rail 15 and first slide seat 16.

[0038] One of the two upper ends of the scissor-type lifting rod 17 is hinged to the second slide rail 18 , and the other end of the two upper ends of the scissor-type lifting rod 17 is hinged to the bottom of the adjacent second sliding seat.

[0039] Two first fixed plates 19 spaced apart on the left and right are fixed on the first slide rail 15, and a push-pull device 20 is fixed on the opposite sides of the two first fixed plates 19. The push-pull device 20 in this embodiment adopts a cylinder. The end of the push-pull device 20 away from the first fixed plate 19 is fixedly connected to the second fixed plate 21, and the second fixed plate 21 is fixed on the first sliding seat 16.

[0040] A fireproof and heat-insulating cloth 26 is fixedly connected between the box cover 14 and the bottom of the groove of the heat-resistant equipment box body 13.

[0041] An electric control box 12 is fixed on the support frame 2. A power supply system is installed in the electric control box 12. The power supply system in this embodiment includes a battery and an inverter. The battery and the inverter are electrically connected. In order to facilitate the operator to stand on the third-level platform 10 to operate various devices, such as Figure 1As shown, in this embodiment, a third vertical pole 22 is fixedly mounted on the top of the third platform 10. To minimize the impact of the third vertical pole 22 on the operator when folding the parachute, the third vertical pole 22 is located at the rear edge of the standing platform. A mounting plate 23 is fixedly mounted on the top of the third vertical pole 22. A controller 24 is fixedly mounted on the top of the mounting plate 23. Controller 24 is electrically connected to the inverter of the power supply system and is respectively connected to the mobile device 1, the push-pull device 20, the electric rotating platform, and the lifting device. In this embodiment, controller 24 is a PLC controller.

[0042] In order to provide a support point for the operator to maintain a stable posture when the mobile device 1 is moving, such as Figure 1 As shown, a handrail 25 is fixedly provided on the mounting plate 23. The handrail 25 is a door-shaped rod structure, and the slot enclosed by the handrail 25 is a transparent structure from top to bottom.

[0043] Working principle: After the aircraft stops, the operator stands on the third-level platform 10 and controls the mobile device 1 to move through the controller 24. When it moves to the rear end of the parachute, the operator controls the electric rotating platform to drive the supporting base 2 to rotate so that the side where the operator stands faces the side of the parachute, controls the mobile device 1 to move forward slowly, and at the same time gradually pulls the parachute from the tail to the second-level platform 8 and the first-level platform 3, and folds the parachute from the tail.

[0044] When the mobile device is about to move to the drag parachute installation location on the aircraft, the operator raises the fireproof and heat-insulating lifting devices on both sides and drives the support frame 2 to rotate using the electric rotating platform, aligning the passage formed by the left and right fireproof and heat-insulating lifting devices with the drag parachute installation location. The operator then continues to slowly move toward the drag parachute installation location and fine-tune the height of the support frame 2 and the standing platform using the lifting devices until the operator can install the folded drag parachute into the drag parachute installation location. The mobile device 1 and lifting device then stop moving to reinstall the drag parachute. Once installation is complete, the operator controls the mobile device 1 to move away from the aircraft parking area.

[0045] Example 2: A mobile parachute installation ladder. This example differs from Example 1 in that no lifting device is provided on the top of the electric rotating platform. Instead, the top of the electric rotating platform is directly fixedly connected to the bottom of the supporting base frame 2. The rest of the structure is the same as that of Example 1.

[0046] Example 3: A mobile deceleration parachute installation ladder. This example differs from Example 2 in that the electric rotating platform is no longer installed on top of the electric rotating platform. Instead, the bottom of the supporting frame 2 is directly fixedly connected to the top of the mobile device 1. The rest of the structure is the same as that of Example 1.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
