Technical Field

[0001] The present application relates to the field of shelf trucks, and in particular to a shelf truck used for storage and transportation of aircraft engine parts. Background Art

[0002] Aircraft need to have a high degree of safety and reliability. After each flight mission, the aircraft must be inspected and maintained to promptly detect potential risks in the aircraft engine and ensure that the aircraft engine can successfully perform the flight mission.

[0003] When operators are overhauling aircraft engines, they need to use a variety of auxiliary tools and numerous accessories. However, due to the large distance between the maintenance site and the material storage room, a shelf truck is needed to carry a large number of tools and accessories to facilitate operators to quickly complete the maintenance process.

[0004] In existing maintenance vehicles, a frame is usually used to accommodate accessories, and a plurality of guide wheels are used to achieve the purpose of guidance, so that operators can move the frame with the accessories placed on it. However, since the accessories themselves have a certain gravity, as the number of accessories placed on the frame increases, the frame and the plurality of guide wheels will be subjected to a greater force, causing the frame to deform, and the accessories placed on the frame are at risk of falling along the frame. There is room for improvement. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a shelf vehicle for storing and transporting aircraft engine parts. Figure 1 and Figure 2 A shelf vehicle for storing and transporting aircraft engine parts includes a shelf body 1, two groups of support assemblies 2 and a sliding assembly 3. The shelf body 1 is provided with a plurality of storage layers 4, and the storage layers 4 are used to accommodate accessories. The two groups of support assemblies 2 are symmetrically arranged on the shelf body 1 along the geometric center of the width direction of the shelf body 1. The two groups of support assemblies 2 are used to support the shelf body 1. The sliding assembly 3 is arranged on the support assembly 2, and the sliding assembly 3 is used to carry the support assembly 2 and the shelf body 1 for movement.

[0033] Specifically, the shelf body 1 can be made of metal material. In the present embodiment, in order to reduce the weight of the shelf body 1 itself, it is preferably made of aluminum pipe. The shelf body 1 includes a main frame 11 and a cross frame 12. The main frame 11 is made of four aluminum pipes. At the same time, the number of cross frames 12 is the same as the number of storage layers 4. The cross frames 12 are connected to the main frame 11 one by one along the same horizontal plane by four aluminum pipes. Several layers of cross frames 12 are evenly distributed on the main frame 11 along the length direction of the main frame 11.

[0034] Furthermore, the number of storage layers 4 can be adjusted according to actual storage needs and the carrying capacity of the main frame 11 and the cross frame 12. Accommodating accessories by using several layers of storage layers 4 is conducive to achieving the purpose of classified storage of different types of accessories. In this embodiment, the number of storage layers 4 and the number of cross frames 12 are set to four layers, and the four storage layers 4 cooperate with the cross frame 12 in the same manner.

[0035] Correspondingly, in order to improve the stability of the connection between the main frame 11 and the cross frame 12, support blocks 10 are provided at the connection between the cross frame 12 and the main frame 11. The support blocks 10 are respectively connected to the main frame 11 and the cross frame 12 by bolts, thereby reducing the probability of deformation of the cross frame 12 along the main frame 11.

[0036] At the same time, the two groups of support components 2 are located on the bottom cross frame 12 of the main frame 11, and the two groups of support components 2 are symmetrically arranged at the two edges of the cross frame 12 along the central axis of the length direction of the cross frame 12. The two groups of support components 2 share the force exerted by the storage layer 4 with accessories on the shelf body 1, which is beneficial to reduce the probability of deformation of the shelf body 1 due to excessive force on the shelf body 1, and plays a positive guiding role in improving the stability of the shelf cart when accommodating accessories.

[0037] Reference Figure 1 and Figure 2 The supporting assembly 2 includes a main supporting member 21 and a secondary supporting member 22. One end of the main supporting member 21 is connected to the shelf body 1, and the other end of the main supporting member 21 is connected to the sliding assembly 3. One end of the secondary supporting member 22 is connected to the shelf body 1, and the other end of the secondary supporting member 22 is connected to the main supporting member 21.

[0038] Specifically, since the components and installation methods of the two groups of support assemblies 2 are the same, any one of the groups is described in detail below. A transition gap 9 is provided between the two groups of support assemblies 2, and the transition gap 9 increases the spatial distance between the shelf body 1 and the contact surface, so that the shelf body 1 can directly pass through workpieces or articles with a height less than the transition gap 9 without shifting the workpieces or articles again, thereby reducing the space occupied by the shelf body 1.

[0039] At the same time, the main support member 21 includes two support rods 211 and a transverse support rod 212. One end of the two support rods 211 is vertically connected to one side of the cross frame 12 located at the bottom layer of the main frame 11. At the same time, the other ends of the two support rods 211 are respectively connected to the transverse support rod 212. When the transverse support rod 212 is connected to the two support rods 211, the transverse support rod 212 is arranged parallel to the cross frame 12.

[0040] Furthermore, a connecting rod 5 is provided between the main support member 21 and the auxiliary support member 22, and the connecting rod 5 is used to connect the main support member 21 and the auxiliary support member 22. The auxiliary support member 22 is made of the same material as the supporting member. The auxiliary support member 22 includes three auxiliary support rods, and one end of the three auxiliary support rods is connected to the horizontal frame 12 located at the bottom layer of the main frame 11 at the same intervals in the vertical direction. At the same time, three connecting rods 5 are provided, so as to achieve the purpose of connecting the support rod 211 and the corresponding auxiliary support rods to each other.

[0041] Correspondingly, a reinforcement member 6 is provided at the connection between the auxiliary support member 22 and the connecting rod 5. The external contour of the reinforcement member 6 is set in a right triangle. The connection between the auxiliary support member 22 and the connecting rod 5 is achieved by bolts, so that the spatial position relationship between the connecting rod 5 and the auxiliary support member 22 is set vertically.

[0042] Therefore, most of the weight of the shelf body 1 is borne by the main support 21, and another part of the weight of the shelf body 1 is shared to a certain extent by the secondary support 22, thereby reducing the probability of deformation or breakage of the main support 21 along the connection with the shelf body 1 due to excessive weight borne by the main support 21. At the same time, the overall stability of the shelf body 1 is improved to a certain extent. At the same time, the main support 21 and the secondary support 22 are indirectly connected by the connecting rod 5, which is convenient for assembly and maintenance or replacement of the main support 21 and / or the secondary support 22.

[0043] Reference Figure 2 and Figure 3 The storage layer 4 is slidably arranged on the shelf body 1 , and the storage layer 4 can be taken out along the shelf body 1 .

[0044] Specifically, since the matching relationship between several storage layers 4 and the horizontal frame 12 is the same, any one of the groups is described in detail below. Sliding grooves 101 are provided at both ends along the length direction of the horizontal frame 12, and sliding rails 102 are provided at both ends along the length direction of the storage layer 4. The sliding rails 102 slide and cooperate with the slider, so that the operator can smoothly pull out the storage layer 4 along the horizontal frame 12, and the operator can take out or place accessories. At the same time, the storage layer 4 can be taken out along the shelf body 1 for maintenance.

[0045] Reference Figure 2 and Figure 3 A protective member 7 is provided on the shelf body 1 located at the storage layer 4. When the storage layer 4 is completely located on the shelf body 1, the protective member 7 is in a closed state, and the storage layer 4 can abut against the protective member 7.

[0046] Specifically, the protective member 7 includes a mounting block 71 and a limit block 72. The mounting block 71 is mounted on the main frame 11 located at the cross frame 12. At the same time, the fixed end of the limit block 72 is rotatably connected to the mounting block 71, so that the limit block 72 can rotate along the mounting block 71. When the operator needs to take out the storage plate along the cross frame 12, the limit block 72 can be rotated along the mounting block 71 to release the limit block 72 from abutting against the storage plate.

[0047] Its function is that when the operator moves the shelf body 1 through the sliding assembly 3, the storage layer 4 and the cross frame 12 slide together, and the limiting effect of the limit block 72 reduces the probability of the storage layer 4 being separated from the cross frame 12 due to vibration, thereby improving safety performance.

[0048] Correspondingly, an anti-skid pad 8 is provided on the storage layer 4. The anti-skid pad 8 can be made of anti-skid cloth. The anti-skid pad 8 increases the friction between the accessories placed on the storage layer 4 and the storage layer 4, thereby reducing the probability of the accessories rolling or displacing along the storage layer 4, and causing the accessories to fall off along the storage layer 4.

[0049] Reference Figure 1 and Figure 2 The sliding assembly 3 includes four self-locking universal wheels 31, each two self-locking universal wheels 31 form a group, and each group of self-locking universal wheels 31 is symmetrically installed at two edges of the transverse support rod 212 along the length direction along the central axis of the transverse support rod 212.

[0050] Therefore, when the operator needs to move the shelf body 1, the self-locking universal wheel 31 provides rolling friction for the shelf body 1, which facilitates the operator to move the shelf body 1 smoothly. At the same time, because the self-locking universal wheel 31 has a self-locking function, when the operator moves the shelf body 1 to the specified position, the self-locking universal wheel 31 can be locked, so that the shelf body 1 can stay stably at the specified location.

[0051] The implementation principle of a shelf truck for storage and transportation of aircraft engine parts in the embodiment of the present application is as follows: most of the weight of the shelf body 1 is borne by the main support member 21, and at the same time, another part of the weight of the shelf body 1 is shared to a certain extent by the secondary support member 22, thereby reducing the probability of deformation or breakage of the main support member 21 along the connection with the shelf body 1 due to excessive weight borne by the main support member 21, and also improving the overall stability of the shelf body 1 to a certain extent. At the same time, the sliding cooperation between the storage layer 4 and the cross frame 12 makes it convenient for the operator to take out or place the accessories along the storage layer 4. When the storage layer 4 is completely pushed into the storage layer 4 again, the limiting effect of the limiting plate reduces the probability of the storage layer 4 falling off along the cross frame 12.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
