Description

Technical Field

[0001] The utility model relates to ground handling equipment, in particular to aircraft broadband radio frequency rack disassembly and assembly equipment. Background Art

[0002] The broadband radio frequency rack (hereinafter referred to as the "rack") is located on the left and right sides of the aircraft. It is large in size and heavy (approximately 100 kg). It is a core component of the aircraft and is worth tens of millions of yuan. It is frequently disassembled and assembled during land-based maintenance. It is very difficult to disassemble and assemble the rack manually or with simple tooling.

[0003] To ensure ground maintenance support for aircraft, we developed customized maintenance equipment specifically for the broadband radio frequency rack disassembly and assembly process to assist with disassembly and assembly. Semi-automated equipment was used to reduce labor intensity and improve maintenance efficiency.

[0004] The main problems currently existing in the disassembly and assembly of broadband radio frequency racks are:

[0005] (1) The platform height is high, close to three meters, and it is necessary to use a ladder to climb up during assembly, which reduces personnel safety;

[0006] (2) The engine needs to be rotated vertically during assembly. The engine weighs about two tons and is about five meters long, which makes it less safe to operate.

[0007] (3) The assembly platform needs to be repeatedly moved up and down during the assembly process, which is not convenient;

[0008] (4) The interface of the assembly platform is fixed, with only one degree of freedom of axial movement, making engine docking difficult, time-consuming, and inefficient;

[0009] (5) The rubber tires contact the ground, and the thrust required for overall movement is large;

[0010] (6) There is no moving guide rail, so the positioning accuracy is low during movement. Utility Model Content

[0011] The purpose of the utility model is to provide an aircraft broadband radio frequency rack disassembly and assembly device to solve the shortcomings of poor convenience and low efficiency of aircraft broadband radio frequency rack disassembly and assembly in the prior art.

[0012] The utility model is realized by adopting the following technical scheme: an aircraft broadband radio frequency rack disassembly and assembly device, characterized in that it includes a stacker and a workbench, the workbench is arranged on the lifting platform of the stacker, the workbench includes a lifting frame and a guide rail adjustment mechanism, and the lifting frame and the guide rail adjustment mechanism are slidably connected through the guide rail.

[0013] Furthermore, the lifting frame includes an upper beam and a lower beam, both ends of the upper beam and the lower beam are connected by a guide shaft, and a lifting beam is provided between the upper beam and the lower beam.

[0014] Furthermore, both ends of the lifting beam are respectively slidably connected to the guide shaft, and a screw rod is also provided on the lifting frame. The screw rod passes through the upper beam, the lower beam and the lifting beam. At the same time, the screw rod is rotationally connected to the upper beam and the lower beam through bearings, and the screw rod is threadedly matched with the lifting beam.

[0015] Furthermore, an adjusting hand wheel is provided at the upper end of the screw rod, and the adjusting hand wheel is turned to drive the screw rod to rotate, and at the same time the lifting beam is moved vertically along the direction of the screw rod.

[0016] Furthermore, the two ends of the lifting beam are respectively provided with shift forks, and the shift forks match the shape of the notch at the lower end of the frame.

[0017] Furthermore, the guide rail adjustment mechanism includes a supporting base plate and a wide roller, guide rails are provided on both sides of the wide roller, a sliding plate is slidably connected to the guide rails, and the lower crossbeam is bolted to the sliding plate, so that the lifting frame can slide on the guide rails.

[0018] Furthermore, the sliding direction of the lifting frame on the guide rail is the same as the transmission direction of the wide roller.

[0019] The aircraft broadband radio frequency rack disassembly and assembly device described in the utility model has the following beneficial effects:

[0020] 1) Customized shift fork: Utilizing the gap at the bottom of the frame, a special size shift fork is customized to fit the product. The shift fork can enter a narrow space for operation and simultaneously plays a supporting and positioning role to ensure that the mechanism will not tip over or axially move. The use of rectangular tube ensures strength while achieving lightweight.

[0021] 2) The trapezoidal screw lift adopts a quick-connect interface that can be replaced, and can be assembled on core frames of various aircraft models with different interface forms. It has versatility and scalability. Using this equipment can improve the efficiency of equipment use, reduce the number of equipment, and thus reduce production costs;
