Description

Technical Field

[0001] This utility model relates to the field of helicopter lifting equipment technology, specifically a helicopter main rotor collector ring lifting equipment. Background Technology

[0002] The helicopter rotor shroud is a key component in the helicopter's electrical system, primarily used for the transmission of electrical energy and signals between rotating components (rotor) and stationary components (fuselage), playing a particularly important role in anti-icing and de-icing systems. Existing helicopter rotor shrouds require multiple personnel to work simultaneously from a height during disassembly and assembly, a time-consuming, labor-intensive, and dangerous process. Therefore, this application provides a helicopter main rotor rotor shroud lifting device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a helicopter main rotor collector ring hoist to address the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A helicopter main rotor collector ring lifting device includes two clamping bars, a connecting disc, a lifting rope, and a sling. Both clamping bars are arc-shaped and can be symmetrically joined to form a ring-shaped clamp. The clamp is used to hold the collector ring within an annular groove on its outer wall. Multiple connecting blocks are evenly distributed on the outer side of each clamping bar, and each connecting block has a first connecting hole. A circular connecting disc is positioned above the clamp, and it has multiple second connecting holes corresponding one-to-one with the first connecting holes. The connecting disc is connected to the clamp via the lifting rope, and the two ends of the lifting rope are detachably connected to the first and second connecting holes. A lifting ring is provided on the connecting disc, and a sling is attached to the lifting ring.

[0006] Furthermore, the inner cylindrical surface of the clamping bar is provided with a notch, and the central angle of the clamping bar is in the range of -°. When two clamping bars are symmetrically spliced ​​to form a complete clamp, an adjustable gap is left at the connection and the connection is fixed by bolts. By adjusting the tightness of the bolts, the gap between the two clamping bars can be adjusted, thereby adjusting the clamping degree of the clamp on the outside of the collector ring. The clamping bar is made of aluminum alloy.

[0007] Furthermore, the number of the connecting block, the first connecting hole, and the second connecting hole are all four.

[0008] Furthermore, a first silicone pad is provided on the upper surface of the clamping strip, the thickness of the first silicone pad being 1.2-1.5mm.

[0009] Furthermore, a second silicone pad is provided on the inner cylindrical surface of the clamping strip, and the thickness of the second silicone pad is 0.8-1mm.

[0010] Furthermore, the suspension rope is a plastic-coated steel cable.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0012] This invention changes the existing method of disassembling and assembling ferrules, which requires multiple people to work together at height. By using this lifting device, personnel can avoid being in a dangerous environment at height for a long time, thus reducing safety risks.

[0013] This lifting tool allows a single person or a small group of people to complete the disassembly and assembly of the collector ring without the need for multiple people to work together, saving manpower and time costs and making the disassembly and assembly process more efficient and convenient.

[0014] Two arc-shaped clamping bars are symmetrically spliced ​​to form a complete clamp. The gap between the clamping bars can be flexibly adjusted by adjusting the tightness of the bolts, so as to adapt to different sizes of current collector rings and achieve stable clamping, ensuring safe and reliable lifting process.

[0015] The clamping bar is made of aluminum alloy, which is lightweight and strong enough; the lifting rope is made of plastic-coated steel cable, which is durable; at the same time, the first and second organic silicone pads are set to protect the surface of the current collector ring and enhance the friction on the inner side of the clamping bar, so as to prevent the current collector ring from being damaged or slipping off during the lifting process.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] like Figure 1-4 As shown, a helicopter main rotor collector ring lifting device includes two clamping bars 1, a connecting disc 2, a lifting rope 3, and a sling 4. Both clamping bars 1 are arc-shaped and can be symmetrically spliced ​​to form a ring-shaped clamp. The clamp is used to hold the collector ring in the annular groove on the outer wall of the collector ring. Multiple connecting blocks 5 are evenly arranged on the outer side of the clamping bars 1. The connecting blocks 5 have first connecting holes 6. The connecting disc 2 is arranged above the clamp. The connecting disc 2 is circular and has multiple second connecting holes 7 that correspond one-to-one with the first connecting holes 6. The connecting disc 2 is connected to the clamp via the lifting rope 3. The two ends of the lifting rope 3 are detachably connected to the first connecting holes 6 and the second connecting holes 7. The connecting disc 2 is provided with a lifting ring 8, and the sling 4 is hung on the lifting ring 8.

[0026] In one embodiment, the inner cylindrical surface of the clamping bar 1 is provided with a notch, and the central angle of the clamping bar 1 is in the range of 172-177°. When two clamping bars 1 are symmetrically spliced ​​to form a complete clamp, an adjustable gap is left at the connection and the connection is fixed by bolts. By adjusting the tightness of the bolts, the gap between the two clamping bars 1 can be adjusted, thereby adjusting the clamping degree of the clamp on the outside of the collector ring. The clamping bar 1 is made of aluminum alloy.

[0027] In one embodiment, the number of connecting blocks 5, the first connecting hole 6, and the second connecting hole 7 are all four.

[0028] In one embodiment, a first silicone pad 9 is provided on the upper surface of the clamping strip 1, and the thickness of the first silicone pad 9 is 1.2-1.5mm.

[0029] In one embodiment, a second silicone pad 10 is provided on the inner cylindrical surface of the clamping strip 1, and the thickness of the second silicone pad 10 is 0.8-1mm.

[0030] In one embodiment, the suspension rope 3 is a plastic-coated steel cable.

[0031] The working process of this utility model is as follows: Two arc-shaped clamping strips 1 are symmetrically spliced ​​on the inner side of the ring groove on the outer wall of the collector ring. Since there is an adjustable gap when the two clamping strips 1 are spliced, bolts are used to fix them through the gap. The tightening degree of the bolts is adjusted according to the actual size of the collector ring so that the clamp is firmly clamped on the collector ring.

[0032] Place the connecting plate 2 above the clamp, and attach the two ends of the lifting rope 3 to the first connecting hole 6 on the connecting block 5 of the clamping strip 1 and the corresponding second connecting hole 7 on the connecting plate 2, respectively, to achieve a movable connection between the connecting plate 2 and the clamp. At this time, the four lifting ropes 3 are symmetrically distributed to ensure a stable connection.

[0033] Connect one end of the sling 4 to the lifting ring 8 on the connecting plate 2, and connect the other end to the external hook to complete the connection between the lifting device and the external lifting equipment.

[0034] The external lifting equipment is activated, and the force is transferred to the clamps through the slings 4, connecting discs 2, and lifting ropes 3, thereby smoothly lifting the current collector ring for subsequent disassembly, assembly, and handling operations. Throughout the lifting process, the silicone pads on the inner side and upper surface of the clamping strips 1 protect the current collector ring and increase friction, preventing damage or slippage.

[0035] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
