Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to an aircraft part lifting equipment. Background Art

[0002] The hoisting machine, also known as the lifting machine, small hoisting machine, etc., mainly consists of rails, flatbed trucks, columns and inclined tie rods, etc., with a small volume and light weight; parts are the basic elements that make up a machine, which can be generally divided into two categories: one is the parts that can be used in various machines (such as gears, shafts, etc.), called general parts; the other is the parts that will only be used in a certain type of machine (such as bolt, propeller, etc.), called special parts; in addition, a combination of parts that work together is also called a component or assembly.

[0003] The existing technology has the following problems:

[0004] When the general parts used on the existing aircraft are in use, due to their large size and heavy weight, it is difficult for manual handling, so a lifting equipment is needed for handling. However, the existing lifting equipment usually uses a hook to lift the parts. When lifting the aircraft part gear, it cannot be directly lifted, and manual operation of the fixture is required to clamp and fix the aircraft part gear before lifting, which reduces the lifting efficiency.

[0005] Therefore, we propose an aircraft part lifting equipment to solve the above drawbacks. Content of the Utility Model

[0006] The purpose of the utility model is to provide an aircraft part lifting equipment to solve the disadvantages existing in the prior art.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: an aircraft part lifting equipment, including a hoisting machine and a lifting assembly, the lifting assembly is hoisted on the hoisting machine through a hook;

[0008] The lifting assembly includes a housing, a guide rod, a lifting rod, a lifting ring, a first moving block, a pulley, a through groove, a second moving block, an anti-slip block, a limit post, a limit block, a support plate and a return spring. A guide rod is fixedly connected to the lower end of the housing. A lifting rod penetrates through the top surface of the housing, and a lifting ring is installed at one end of the lifting rod. The lifting ring is used in cooperation with the hook on the hoisting machine. A first moving block is fixedly connected to the outer wall of the lifting rod, and a pulley is installed on the first moving block. A through groove is formed on the surface of the housing, and a second moving block is slidably connected in the through groove. A support plate is fixedly connected to the top surface of the second moving block. A limit post is welded to the inner wall of the housing, and a limit block is threadedly connected to one end of the limit post. The support plate is slidably connected to the limit post through a through hole formed on the surface. A return spring is sleeved on the outside of the limit post between the inner wall of the housing and the support plate.

[0009] Preferably, an anti-slip block is integrally formed on one side surface of the second moving block, and there are multiple anti-slip blocks. The multiple anti-slip blocks are distributed in a rectangular array on the surface of the second moving block.

[0010] Preferably, the hoisting machine is electrically connected to an external power supply through a wire.

[0011] Preferably, the second moving block is used in cooperation with the first moving block.

[0012] Preferably, there are multiple second moving blocks, and the multiple second moving blocks are distributed in an annular array on the housing.

[0013] Preferably, there are multiple first moving blocks, and the number of the multiple first moving blocks is the same as the number of the second moving blocks.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, by setting the lifting assembly, the lifting ring is connected to the hoisting machine. Before hoisting, the lifting assembly is inserted into the interior of the part, and then the hoisting machine can be started for hoisting. During hoisting, the lifting rod moves upward to drive the first moving block to move upward, so as to squeeze the second moving block out of the through groove, achieving the effect of clamping and fixing the inner wall of the part. On the contrary, after hoisting to the appropriate position, the lifting assembly moves downward under the action of gravity. At this time, the second moving block resets under the action of the return spring to release the part. During the hoisting process, no manual participation is required, and the material taking and placing are convenient and the efficiency is high.

[0016] 2. In the present utility model, by setting the anti-slip block, the friction between the second moving block and the part can be greatly increased, and the stability during hoisting is stronger, avoiding accidents. Description of the Drawings

The support plate 212 is slidably connected with the limiting column 210 through a through hole formed on the surface. A return spring 213 is sleeved on the outer side of the limiting column 210 between the inner wall of the housing 21 and the support plate 212.

[0028] During use, the lifting ring 24 is connected to the hoisting machine 1. Before hoisting, the hoisting assembly 2 is inserted into the interior of the part. Then, the hoisting machine 1 can be started for hoisting. During hoisting, the hoisting rod 23 moves upward, driving the first moving block 25 to move upward, thereby squeezing the second moving block 28 out of the through groove 27, achieving the effect of clamping and fixing the inner wall of the part. Conversely, after hoisting to the appropriate position, the hoisting assembly 2 moves downward under the action of gravity. At this time, the second moving block 28 is reset under the action of the return spring 213 to release the part. The hoisting process does not require manual participation, and the material taking and placing are convenient and efficient. Secondly, by setting the anti-slip block 29, the friction between the second moving block 28 and the part can be greatly increased, and the stability during hoisting is stronger, avoiding accidents.

[0029] In this embodiment: An anti-slip block 29 is integrally provided on one side surface of the second moving block 28, and there are multiple anti-slip blocks 29, and the multiple anti-slip blocks 29 are distributed in a rectangular array on the surface of the second moving block 28.

[0031] In this embodiment: The hoisting machine 1 is electrically connected to an external power source through a wire.

[0032] Specifically, it is a common circuit connection structure and will not be elaborated here.

[0033] In this embodiment: The second moving block 28 is used in cooperation with the first moving block 25.

[0034] Specifically, as shown in the appendix Figure 2 As shown, the surfaces of the second moving block 28 and the first moving block 25 that are close to each other are both inclined surfaces, and when they are used in cooperation, they can convert vertical movement into horizontal movement.

[0035] In this embodiment: There are multiple second moving blocks 28, and the multiple second moving blocks 28 are distributed in a circular array on the housing 21.

[0036] Specifically, it improves the stability when hoisting aircraft gear parts.

[0038] Specifically, it can be used in cooperation with the second moving block 28, and the structure is compact.

[0039] Working principle: When in use, connect the lifting ring 24 to the hoist 1. Before hoisting, insert the hoisting component 2 into the interior of the part. Then, start the hoist 1 for hoisting. During hoisting, the hoisting rod 23 moves upward, driving the first moving block 25 upward, thereby squeezing the second moving block 28 out of the through groove 27, achieving the effect of clamping and fixing the inner wall of the part. Conversely, after hoisting to the appropriate position, the hoisting component 2 moves downward under the action of gravity. At this time, the second moving block 28 is reset under the action of the return spring 213 to release the part. The hoisting process does not require manual participation, and the material taking and placing are convenient and efficient. Secondly, by setting the anti-slip block 29, the friction between the second moving block 28 and the part can be greatly increased, and the stability during hoisting is stronger, avoiding accidents.

[0040] It should be noted that: The model and specification of the hoist 1 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0041] The power supply and its principle of the hoist 1 are clear to those skilled in the art and will not be described in detail here.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
