[0002] The front windshield of an aircraft needs to be lifted when it is disassembled or installed. Currently, it is lifted by binding with slings, and most of the slings are single. There are great safety hazards in lifting a four-sided smooth body such as a front windshield. The front windshield needs to be tightly packed before lifting, and it needs to be disassembled and packed again after lifting, which can easily cause the front windshield to be scratched and dented. Utility Model Content

[0003] In view of this, an object of the present invention is to provide an aircraft front windshield lifting device, which is used to overcome the above-mentioned problems or at least partially solve or alleviate the above-mentioned problems.

[0004] The utility model provides a lifting device for a front windshield of an aircraft, comprising:

[0005] A mesh frame, the mesh frame is made of flexible material, the mesh frame is rectangular, a woven mesh is arranged inside the mesh frame, and a handle is arranged on both sides of the mesh frame;

[0006] A protection pad is matched with the shape of the mesh frame, the protection pad is padded in the mesh frame, and the protection pad is made of a highly elastic material.

[0007] The utility model also has the following optional features.

[0008] Optionally, the protection pad is a rubber-plastic plate.

[0009] Optionally, a flannel cloth is provided on the inner side of the protection pad, and a rainproof and moisture-permeable cloth is provided on the outer side of the protection pad.

[0010] Optionally, a plastic adhesive chain is further provided on the outer side of the protection pad, and a buckle is further provided on the edge of the protection pad.

[0011] Optionally, the net frame, the woven net and the handle are all made of high-strength polyester synthetic fiber.

[0012] Beneficial effects of the utility model:

[0013] The utility model discloses a front windshield lifting device for an aircraft, wherein a woven net is arranged in a net frame, handles are arranged on both sides of the net frame, and a protective pad is arranged in the net frame. When the front windshield of the aircraft is disassembled and assembled, the front windshield can be placed on the protective pad in the net frame, and then the two handles are hung by a crane to lift the front windshield. The front windshield does not need to be packaged and disassembled, and can be prevented from being scratched or knocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; DETAILED DESCRIPTION

[0020] Example 1

[0021] refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides a lifting device for the front windshield of an aircraft, comprising: a mesh frame 1 and a protection pad 4; the mesh frame 1 is made of flexible material, the mesh frame 1 is rectangular, a woven mesh 2 is arranged inside the mesh frame 1, and a handle 3 is arranged on both sides of the mesh frame 1; the protection pad 4 is padded in the mesh frame 1, and the protection pad 4 is made of highly elastic material.

[0022] The four sides of the mesh frame 1 are all 1800mm long, and each side of the frame 1 is 40mm wide and 25mm thick; the thickness and width of the mesh bundle in the woven mesh 2 are both 25mm, and the mesh size is 125×125mm; each handle 3 is 25mm thick, 40mm wide, and 2700mm long; the protective pad 4 is square, and its four sides are all 1300mm long. The protective pad 4 is 10mm thick, and two sewing lines are also provided on the protective pad 4 to bend and deform with the windshield. Before lifting the windshield, unfold the mesh frame 1 and the woven mesh 2, pad the protective pad 4 in the mesh frame 1, and then put the windshield on the protective pad 4, and finally hang the two handles 3 by the crane for lifting.

[0023] Example 2

[0024] refer to Figure 2 and Figure 3, based on Example 1, the protection pad 4 is a rubber-plastic plate.

[0025] The rubber-plastic board undergoes a special foaming process to form a dense foamed air-tight chamber inside, making it highly elastic and also heat-resistant and cold-resistant.

[0026] Example 3

[0027] refer to Figure 4 On the basis of Example 2, a flannel cloth 5 is provided on the inner side of the protection pad 4, and a rainproof and moisture-permeable cloth 6 is provided on the outer side of the protection pad 4.

[0028] The inner side of the protection pad 4 with flannel 5 is in contact with the windshield, which also protects the protection pad 4 from being scratched by the windshield. The outer side of the protection pad 4 is provided with rainproof and breathable cloth 6 for contacting with the woven mesh, which can also prevent rainwater from penetrating into the protection pad 4 and the windshield.

[0029] Example 4

[0030] refer to Figure 2 On the basis of Example 1, a plastic adhesive chain 7 is further provided on the outer side of the protection pad 4 , and a buckle 8 is further provided on the edge of the protection pad 4 .

[0031] The outer side of the protection pad 4 is connected to the woven net 2 through a plastic adhesive chain 7, and the edge of the protection pad 4 is connected to the net frame 1 through a buckle 8, which can prevent the protection pad 4 from slipping off.

[0032] Example 5

[0033] refer to Figure 1 On the basis of Example 1, the mesh frame 1, the woven mesh 2 and the handle 3 are all made of high-strength polyester synthetic fiber.

[0034] The high-strength polyester synthetic fiber has high strength, which enables the handle 3 with a cross-section of 25×40mm to weigh 1000kg, thereby ensuring the safety of hoisting. The net frame 1, the woven net 2 and the handle 3 are all sewn into a whole by high-strength polyester thread.

[0035] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims. The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry, and are not described here one by one.
