Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance platform technology, and in particular to a quick-assembly multi-layer maintenance platform for aircraft maintenance. Background Technology

[0002] Currently, most aircraft maintenance platforms adopt a fixed structure, and the top of the platform cannot be extended or retracted. Therefore, during maintenance of different widths, it is necessary to move the entire base to move the entire platform, ultimately achieving maintenance of different widths. The aforementioned maintenance platforms are inflexible and have low work efficiency.

[0003] A search revealed that prior art CN213384780U discloses a top-mounted retractable maintenance platform mounted on an aircraft maintenance platform. It includes a bottom platform frame, with a top platform frame supported by multiple columns. A top working platform is fixed to the top of the top platform frame. Multiple sets of roller supports are symmetrically arranged on both sides between the bottom and top platforms. An extended platform frame is supported by guide wheels between these roller supports. An extended platform plate is fixed to the top of the extended platform frame. A telescopic power device for driving the extended platform plate's extension is provided between the extended platform plate and the bottom platform frame. This maintenance platform can be easily and effectively extended in its length direction, thus adapting to aircraft maintenance of varying widths.

[0004] The aforementioned maintenance platform can form a two-tiered stepped platform for maintenance personnel to stand on after extending the extended platform plate. The height can be adjusted by the lifting action of the lifting platform. However, no protective mechanism is set after the extended platform plate is extended, which makes the safety of maintenance personnel standing on the extended platform plate poor. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-installation multi-layer maintenance platform for aircraft maintenance, which aims to solve the problem that the lack of protective mechanisms in existing maintenance platforms after their width is extended and retracted, resulting in poor safety for maintenance personnel when standing on the extended platform.

[0006] To achieve the above objectives, this utility model provides a quick-assembly multi-layer maintenance platform for aircraft maintenance, including a fixed platform and a telescopic platform, wherein the telescopic platform is disposed on one side of the bottom of the fixed platform, and a protective mechanism is also included.

[0007] The protective mechanism includes a connecting rod, a protective plate, a plug-in plate, a positioning rod, a locking knob, a T-shaped platform, a limiting ball, a support device, a fixed protective device, a drive device, and a guide device. The connecting rod is threadedly connected to the telescopic platform and is symmetrically arranged. The protective plate is slidably connected to the connecting rod and is located between the connecting rods. The positioning rod is integrally arranged on the bottom side of the plug-in plate. The plug-in plate is detachably connected to the connecting rod. The positioning rod is slidably connected to the telescopic platform. The locking knob is threadedly connected to the connecting rod and is located at the top of the connecting rod. The T-shaped platform is detachably connected to the fixed platform and is located above the telescopic platform. The limiting ball is located at the bottom of the T-shaped platform and can roll against the top end face of the telescopic platform. The support device is located below the telescopic platform. The fixed protective device is detachably installed on the fixed platform. The drive device is located on the fixed platform and is connected and fixed to the telescopic platform. The guide device is located on both sides of the telescopic platform.

[0008] The fixed protective device can be configured as an L-shaped structure or a U-shaped structure.

[0009] The guiding device includes a guide seat and a guide rod assembly. The guide seat is fixedly connected to the telescopic platform and is symmetrically arranged. The guide rod assembly is disposed on the fixed platform and slides with the guide seat.

[0010] The guide rod assembly includes a fixed base and a stabilizing guide rod. The fixed base is detachably connected to the fixed platform and is symmetrically arranged. The stabilizing guide rod is slidably engaged with a T-shaped linear sliding bearing installed on the guide base, and its two splined ends are directly slidably inserted into the spline cavity on the fixed base.

[0011] The quick-assembly multi-layer maintenance platform for aircraft maintenance also includes a stabilization mechanism, which includes a stabilizing seat and stabilizing balls. The stabilizing seat is detachably connected to the fixed platform and is symmetrically arranged. The stabilizing balls are disposed on the stabilizing seat and make rolling contact with the bottom end face of the telescopic platform.

[0012] This utility model discloses a quick-installation multi-layer maintenance platform for aircraft maintenance. In use, the fixed lugs at the bottom of the fixed platform are fixedly connected to the top of the external lifting platform. When widening is required, the drive device is activated to move the telescopic platform, forming a two-tiered platform structure with the fixed platform. This facilitates standing for maintenance personnel. Simultaneously, after the telescopic platform extends, two connecting rods are installed on the ends of the telescopic platform away from the fixed platform. Protective plates and plug-in plates are then slidably installed on these rods. Finally, a threaded locking knob is installed on the top of the connecting rods. The protective plate and plug-in plate work together to form a U-shaped protective structure, improving the safety of maintenance personnel standing on the extended platform. This solves the problem of poor safety for maintenance personnel standing on the extended platform due to the lack of protective mechanisms in existing maintenance platforms after expansion.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Example 1:

[0022] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a quick-assembly multi-layer maintenance platform used for aircraft maintenance. Figure 2 This is a schematic diagram of the retracted telescopic platform 102. Figure 3 This is a front view of the support device 110.

This solution solves the problem of poor safety for maintenance personnel standing on the extended platform after the existing maintenance platform has been extended due to the lack of a protective mechanism. It is understood that the aforementioned solution improves the safety of maintenance personnel standing on the extended platform 102.

[0023] In this embodiment, the telescopic platform 102 is disposed on one side of the bottom of the fixed platform 101, and the fixed platform 101 is directly mounted on the top of the lifting platform through mounting ears symmetrically arranged on both sides. The telescopic platform 102 is L-shaped.

[0024] The connecting rod 103 is threadedly connected to the telescopic platform 102 and symmetrically arranged. The protective plate 104 is slidably connected to the connecting rod 103 and located between the connecting rods 103. The positioning rod 106 is integrally arranged on the bottom side of the plug-in plate 105. The plug-in plate 105 is detachably connected to the connecting rod 103. The positioning rod 106 is slidably connected to the telescopic platform 102. The locking knob 107 is threadedly connected to the connecting rod 103 and located on the top of the connecting rod 103. The T-shaped platform 108 and... The fixed platform 101 is detachably connected and located above the telescopic platform 102. The limiting ball 109 is disposed at the bottom of the T-shaped platform 108 and can roll against the top end face of the telescopic platform 102. The support device 110 is disposed below the telescopic platform 102. The fixed protective device 111 is detachably installed on the fixed platform 101. The drive device 112 is disposed on the fixed platform 101 and is connected and fixed to the telescopic platform 102. The guide device is disposed on both sides of the telescopic platform 102. The bottom of the connecting rod 103 has an external thread end, which can be directly installed into the threaded hole on the telescopic platform 102. The connecting rod 103 has two non-communicating T-shaped grooves in an L-shape. The top of the connecting rod 103 has a stepped external thread end for easy installation of the locking knob 107. The T-shaped sliding parts on both sides of the protective plate 104 are directly slidably installed in the T-shaped grooves of the connecting rod 103. The bottom of the insertion plate 105 has a positioning rod 106, which can be inserted into the positioning hole of the telescopic platform 102. The T-shaped sliding part of the insertion plate 105 can be inserted into the T-shaped groove of the connecting rod 103. The T-shaped platform 108 is open. The telescopic platform 102 is mounted on the bottom of the fixed platform 101 via positioning pins and bolts. A limiting ball bearing 109 is rolled on the bottom of the T-shaped platform 108. The limiting ball bearing 109 cooperates with the support device 110 to achieve sliding support and vertical limiting of the telescopic platform 102. The support device 110 consists of a support base and rollers. The rollers slide against the bottom end face of the telescopic platform 102 and are mounted on the support base via T-shaped pins and nuts. The support base is fixed by bolts and positioning pins arranged from bottom to top. The fixed protective device 111 provides safety protection when standing on the fixed platform 101. The guide device is used for the movement of the telescopic platform 102. The drive device 112 is a hydraulic cylinder, and the output end of the hydraulic cylinder is connected and fixed to the telescopic platform 102.

[0025] Secondly, the fixed protective device 111 can be configured as an L-shaped structure or a U-shaped structure. After the fixed protective device 111 is installed, maintenance personnel can be sent to the fixed platform 101 via external lifting equipment.

[0026] Then, the guide seat 113 is fixedly connected to the telescopic platform 102 and arranged symmetrically; the guide rod assembly is disposed on the fixed platform 101 and slides with the guide seat 113. The guide seat 113 has a T-shaped structure and is fixed by a positioning pin and bolts. A T-shaped linear sliding bearing is installed in its through hole, and the guide rod assembly is used for guiding the engagement.

[0027] Finally, the fixed base 114 is detached from the fixed platform 101 and symmetrically arranged; the stabilizing guide rod 115 is slidably engaged with the T-shaped linear sliding bearing installed on the guide seat 113, and its two splined ends are directly slidably inserted into the spline cavity on the fixed base 114. The fixed base 114 is L-shaped and is fixed to the fixed platform 101 by bolts and positioning pins. The fixed base 114 is provided with a spline cavity that engages with the stepped splined ends on both sides of the stabilizing guide rod 115. This structure helps to prevent the stabilizing guide rod 115 from rotating.

[0028] When using this utility model to solve the problem of poor safety for maintenance personnel standing on the extended platform due to the lack of a protective mechanism after the existing maintenance platform has been extended in width, the fixing lugs at the bottom of the fixed platform 101 are fixedly connected to the top of the external lifting platform. Then, when it is necessary to widen the platform, the drive device 112 is controlled to move the telescopic platform 102, thus forming a two-stage stepped platform structure with the fixed platform 101, which is convenient for maintenance personnel to stand on. At the same time, after the telescopic platform 102 is extended, the two connecting rods 103 are first installed on the end of the telescopic platform 102 away from the fixed platform 101, and then the protective plate 104 and the plug-in connector are slidably installed on them. Plate 105, and finally, the threaded locking knob 107 is installed on the top of the connecting rod 103 for limiting. The protective plate 104 and the plug plate 105 cooperate to form a U-shaped protective structure, which improves the safety of maintenance personnel standing after the telescopic platform 102 is extended. When the telescopic platform 102 needs to be retracted, first rotate and remove the two locking knobs 107, then directly remove the protective plate 104 and the plug plate 105, and finally control the drive device 112 to drive the telescopic platform 102 to retract. This can solve the problem that the existing maintenance platform lacks a protective mechanism after its width is extended, resulting in poor safety for maintenance personnel standing on the extended platform plate.
