[0035] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of an engine transfer device provided by an embodiment of the present disclosure. Figure 1 As shown, the engine transport device includes: a base 10 and a pallet rack 20 . The pallet rack 20 includes a bottom plate 21 , a positioning plate 22 and a positioning arm 23 . The positioning plate 22 and the positioning arm 23 are both located on one side of the bottom plate 21 .

[0038] Figure 2 Schematic diagram of the structure of a tray rack 20 provided in an embodiment of the present disclosure. Figure 2 As shown, the first side 221 of the positioning plate 22 is slidably connected to the bottom plate 21 , the sliding direction of the positioning plate 22 is parallel to the first side 221 , and the positioning plate 22 has a first connection structure for connecting to the engine.

[0039] like Figure 2 As shown, one end of the positioning arm 23 is hinged on the base plate 21, the rotating axis of the positioning arm 23 is parallel to the first side 221, the positioning arm 23 has a second connecting structure for connecting to the engine, and the positioning plate 22 and the positioning arm 23 are arranged relative to each other in a direction perpendicular to the sliding direction.

[0040] like Figure 1 As shown, the base 10 is located on the other side of the bottom plate 21 and is connected to the bottom plate 21 .

[0041] The engine transfer device provided by the embodiment of the present disclosure includes a base 10 and a tray rack 20 located on the base 10, wherein a positioning plate 22 and a positioning arm 23 in the tray rack 20 are relatively distributed on the bottom plate 21. The positioning plate 22 can be slidably arranged on the bottom plate 21 along a first side 221. By sliding and adjusting the position of the positioning plate 22 on the bottom plate 21, the first connection structure of the positioning plate 22 can be adjusted to a position relative to the connection position of engines of different specifications, so that the positioning plate 22 can be adapted to the fixing operation of engines of different specifications. At the same time, one end of the positioning arm 23 is hinged to the bottom plate 21, and the rotation axis of the positioning wall is parallel to the first side 221. By rotating the positioning arm 23, the positioning arm 23 can be moved closer to or away from the positioning plate 22. When it is necessary to fix the engine, the positioning arm 23 can flexibly adjust the swing angle of the positioning arm 23 according to the engine specifications, so that the second connection structure on the positioning arm 23 can be opposite to the connection position of the engine of different specifications, thereby enabling the positioning arm 23 to be fixedly connected to the engine of different specifications. Moreover, since the positioning plate 22 and the positioning arm 23 are arranged relative to each other, after the engine is fixed on the pallet rack 20, it is located between the positioning plate 22 and the positioning arm 23. The positioning plate 22 and the positioning arm 23 respectively fix the engine on both sides of the engine. Therefore, the connection reliability between the engine and the pallet rack 20 can be effectively improved, preventing the engine from falling off easily and improving safety.

[0042] Figure 3 1 is a schematic structural diagram of a base 10 provided in an embodiment of the present disclosure. Figure 3 As shown, the base 10 includes a truss-type frame structure, which enables the frame structure to have a large-sized hollow, thereby achieving the lightness of the engine transfer device to the greatest extent and facilitating transportation.

[0043] like Figure 3 As shown, the frame structure has two parallel locking rods 11 , and the locking rods 11 are provided with a plurality of screw holes, which are arranged at intervals along the axial direction of the locking rods 11 .

[0044] In the above implementation, the screw holes on the locking rods 11 are used for connecting the tray rack 20 to the base 10 using bolts, thereby fixing the tray rack 20 on the base 10 .

[0045] Among them, the multiple screw holes on the locking rod 11 can be used to install multiple tray racks 20 on the base 10, thereby achieving the purpose of fixing multiple engines on one base 10 at the same time.

[0046] For example, Figure 1 As shown, three pallet racks 20 are installed on the base 10 at the same time, and the three pallet racks 20 are arranged side by side. The three pallet racks 20 are all threadedly connected to the screw holes on the locking rod 11 through bolts.

[0047] Alternatively, as Figure 1 、 3 As shown, the engine transfer device also includes at least three legs 12, which are arranged in parallel and spaced apart on the base 10. The end surface of one end of the leg 12 is provided with a sleeve hole 121, and the end surface of the other end of the leg 12 is provided with a guide cone 122 that cooperates with the sleeve hole 121.

[0048] For example, Figure 3 As shown, the engine transport device includes four legs 12, which are arranged in parallel and spaced apart on a base 10. The base 10 is rectangular, and the four legs 12 are located at the four corners of the base 10. This can prevent the legs 12 from being distributed in the central area of ​​the base 10 and taking up more space for the engine.

[0049] For example, the sleeve hole 121 on the supporting leg 12 may be a conical hole, and the larger end of the conical hole is located at the end surface of one end of the supporting leg 12 .

[0050] Exemplarily, the guide cone 122 on the leg 12 may be a cone, with the larger end of the cone located at the end surface of the other end of the leg 12 .

[0051] In the disclosed embodiment, the conical hole on the support leg 12 is used for inserting the cone on the support leg 12. In this way, after the engine is fixedly placed on the first engine transfer device, the conical hole of the support leg 12 of the second engine transfer device is inserted into the cone of the support leg 12 of the first engine transfer device, thereby achieving the purpose of placing the second engine transfer device above the first engine transfer device.

[0052] In the above implementation, a support leg 12 is provided on the base 10, and a sleeve hole 121 and a guide cone 122 are provided at both ends of the support leg 12, so that multiple engine transfer devices can be stacked together, thereby saving the space occupied by the engine transfer device to the greatest extent.

[0053] Optionally, the maximum aperture of the conical hole can be smaller than the maximum diameter of the cone, so that after the cone is inserted into the cylindrical hole, the outer wall of the cone and the inner wall of the conical hole can be ensured to fit tightly together, thereby preventing the problem of the legs 12 being loose due to insufficient connection after the two legs 12 are docked.

[0054] Alternatively, as Figure 2 As shown, the first connection structure includes an opening 31 . The opening 31 is located at the second side 222 of the positioning plate 22 . The first side 221 and the second side 222 are opposite sides.

[0055] In the above implementation, an opening 31 extending toward the first side 221 is provided on the second side 222 of the positioning plate 22, so that the positioning plate 22 forms a fork-shaped structure. The opening 31 of the positioning plate 22 faces in a direction away from the base plate 21, which facilitates the engagement of the opening 31 with the structure on the engine, thereby facilitating fixing the engine on the positioning plate 22.

[0056] Alternatively, as Figure 2 As shown, the first connection structure further includes a first strip hole 32 . The length direction of the first strip hole 32 is perpendicular to the bottom plate 21 . The first strip hole 32 is located on the plate surface of the positioning plate 22 .

[0057] For example, Figure 2 As shown, the first connection structure includes two first strip-shaped holes 32 . The two first strip-shaped holes 32 are respectively located on both sides of the opening 31 , and the length direction of the two first strip-shaped holes 32 is the same as the extension direction of the opening 31 .

[0058] In the disclosed embodiment, the first strip-shaped hole 32 is used for bolts to pass through. After passing through the first strip-shaped hole 32 , the bolts can be connected to the screw holes on the engine housing to fix the engine on the positioning plate 22 .

[0059] Among them, the first strip hole 32 is long and narrow, and the bolt can be inserted into any area of ​​the first strip hole 32 to meet the need of docking the bolt with the screw hole on the engine housing, thereby improving the adaptability of the positioning plate 22 and the engine.

[0060] Alternatively, as Figure 2 As shown, the pallet rack 20 also includes a hinge seat 24 and a limit baffle 25. The hinge seat 24 includes a connecting plate 241 and two hinge plates 242. The two hinge plates 242 are distributed in parallel on the bottom plate 21. The connecting plate 241 is located between the two hinge plates 242, and the two side edges are respectively connected to the two hinge plates 242. The connecting plate 241 and the hinge plates 242 are both perpendicular to the bottom plate 21.

[0061] Figure 4 Schematic diagram of the structure of a positioning arm 23 provided by an embodiment of the present disclosure. Figure 2 、 4 As shown, one end of the positioning arm 23 is located between the two hinge plates 242 , and one end of the positioning arm 23 and the two hinge plates 242 are provided with hinge holes 243 , and the rotating shaft of the positioning arm 23 is inserted into the hinge hole 243 .

[0062] In the above implementation, the hinged seat 24 is designed as a U-shaped structure. A connecting plate 241 is provided on the side of the U-shaped structure facing the positioning plate 22 to block the rotation of the positioning arm 23 toward the positioning plate 22 and define the minimum distance between the second connecting structure of the positioning arm 23 and the first connecting structure of the positioning plate 22. The side of the U-shaped structure facing away from the positioning plate 22 is open, allowing the positioning arm 23 to rotate, thereby adjusting the distance between the positioning arm 23 and the positioning plate 22. This allows engines of different specifications to be sandwiched between the positioning plate 22 and the positioning arm 23, thereby improving the applicability of the pallet rack 20.

[0063] like Figure 2 As shown, the limiting baffle 25 is connected to the bottom plate 21 , and the limiting plate is opposite to the connecting plate 241 , and the positioning arm 23 is located between the limiting baffle 25 and the connecting plate 241 .

[0064] By setting the limiting baffle 25, the positioning arm 23 will abut against the limiting baffle during the rotation process to prevent the positioning arm 23 from continuing to rotate to a greater extent, thereby limiting the maximum distance between the second connection structure of the positioning arm 23 and the first connection structure of the positioning plate 22.

[0065] In this way, when the positioning arm 23 rotates to be inclined with the base plate 21 , the limiting baffle 25 supports the positioning arm 23 , preventing the hinge seat 24 from bearing the load alone, thereby improving reliability.

[0066] For example, a telescopic rod may be provided on a side of the limiting baffle 25 away from the bottom plate 21 , one end of the telescopic rod is connected to the limiting baffle 25 , and the other end of the telescopic rod is used to abut against the positioning arm 23 .

[0067] In the above implementation, no matter what state the positioning arm 23 rotates to, the telescopic rod can be controlled to extend and retract, so that the end of the telescopic rod rests against the positioning arm 23, so that the telescopic rod and the hinge seat 24 support the positioning arm 23 together, thereby improving the reliability of the positioning arm 23.

[0068] Alternatively, as Figure 2 、 4 As shown, the second connection structure includes a second strip hole 33 , the length direction of the second strip hole 33 is parallel to the bottom plate 21 , and the second strip hole 33 is located at the other end of the positioning arm 23 .

[0069] For example, Figure 2 、 4 As shown, the second connection structure includes a second strip hole 33 , which is located at the end of the positioning arm 23 away from the bottom plate 21 , and the length direction of the second strip hole 33 is parallel to the bottom plate 21 .

[0070] In the disclosed embodiment, the second strip-shaped hole 33 is used for passing bolts. After passing through the second strip-shaped hole 33 , the bolts can be connected with the screw holes on the engine housing to fix the engine on the positioning arm 23 .

[0071] Among them, the second strip hole 33 is long and narrow, and the bolt can be inserted into any area of ​​the second strip hole 33 to meet the need of docking the bolt with the screw hole on the engine casing, thereby improving the adaptability of the positioning arm 23 and the engine.

[0072] Figure 5 Schematic diagram of the structure of a positioning arm 23 provided by an embodiment of the present disclosure. Figure 5 As shown, the positioning arm 23 includes an elastic section 231 and a rigid section 232 , one end of the elastic section 231 is coaxially connected to one end of the rigid section 232 , the hinge hole 243 is located at the other end of the elastic section 231 , and the second strip hole 33 is located at the other end of the rigid section 232 .

[0073] For example, the elastic section 231 and the rigid section 232 of the positioning arm 23 can be made of different materials. For example, the elastic section 231 is a rubber column, and the rigid section 232 is a metal column.

[0074] In one implementation, the rubber column and the metal column can be bonded with an adhesive. After the end surface of the rubber column is polished smooth, the adhesive is applied to one end of the rubber column and one end of the metal column. Then, the one end of the rubber column and one end of the metal column are docked to achieve the connection between the rubber column and the metal column.

[0075] Alternatively, the cross-sectional area of ​​the metal post can be larger than that of the rubber post, and a groove can be provided on the end surface of the metal post so that the rubber post can be inserted into the groove. In this way, inserting the rubber post into the groove of the metal post can improve the connection reliability of the rubber post and the metal post.

[0076] In another implementation, a screw hole is provided at one end of the rubber column, and a stud is provided at one end of the metal column. The stud is screwed into the screw hole to achieve the purpose of threaded connection between the rubber column and the metal column.

[0077] For example, the elastic section 231 and the rigid section 232 of the positioning arm 23 may be made of the same material.

[0078] In one implementation, the positioning arm is made of metal. The elastic section 231 is a metal plate. Due to its thinness, the metal plate has a certain toughness, allowing the metal plate to bend and deform, achieving elastic deformation. The rigid section 232 is a metal column with a diameter greater than the thickness of the metal plate. This metal column is not easily bent or deformed and has good rigidity.

[0079] Optionally, the thickness of the metal plate is 2 mm to 5 mm, and the diameter of the metal column is not less than 8 mm.

[0080] Optionally, when both the elastic section and the rigid section are made of metal, the two can be fixedly connected by welding, which is beneficial to improving the manufacturing efficiency of the positioning arm.

[0081] In some other implementations, the positioning arm is made of metal, the elastic section may be a spring, the rigid section may be a metal column, and one end of the spring is connected to one end of the metal column.

[0082] In the above implementation, the elastic section 231 has a certain elasticity. When the positioning arm 23 is rotated to a suitable position and the second connecting structure needs to be fixedly connected to the engine casing, the flexibility of the elastic section 231 allows the positioning arm 23 to be slightly twisted and deformed as a whole, so that the second connecting structure can be accurately aligned with the connection position of the engine casing, thereby improving the applicability of the positioning arm 23.

[0083] Exemplarily, the ratio of the length of the elastic section 231 to the length of the rigid section 232 is not greater than 1. For example, the ratio of the length of the elastic section 231 to the length of the rigid section 232 is 0.5.

[0084] The elastic section 231 is set shorter than the rigid section 232 so that the length of the elastic section 231 does not exceed half of the positioning arm 23. This can prevent the elastic section 231 from being too long and making the positioning arm 23 relatively soft, which is not conducive to fixing the engine.

[0085] Alternatively, as Figure 2 As shown, the pallet rack 20 also includes a first support column 261, a second support column 262, a third support column 263 and a fourth support column 264. The first support column 261, the second support column 262, the third support column 263 and the fourth support column 264 are all distributed in parallel and spaced apart on the bottom plate 21, and the line connecting the position of the first support column 261, the position of the second support column 262, the position of the third support column 263 and the position of the fourth support column 264 is a quadrilateral.

[0086] In the disclosed embodiment, the support columns are used to support the engine so that the engine can be separated from the base plate 21 through the support columns. Since the surface of the engine casing is not a flat plane, in order to avoid the engine being placed unstable on the base plate 21, four support columns are directly provided to support the four areas of the engine, so that the engine can be more stably fixed on the base 10.

[0087] like Figure 2 As shown, the line connecting the first support column 261 and the second support column 262 is parallel to the first side 221 , and the positioning plate 22 is located between the first support column 261 and the second support column 262 .

[0088] The positioning plate 22 is set between the connecting line of the first support column 261 and the second support column 262. In this way, after the engine is placed on the first support column 261 and the second support column 262, it is fixed by the positioning plate 22, which can prevent the engine from easily falling off the first support column 261 and the second support column 262, thereby improving the reliability of the engine transfer device.

[0089] like Figure 2 As shown, the line connecting the third support column 263 and the fourth support column 264 is parallel to the rotation axis of the positioning arm 23 , and the positioning arm 23 is located between the third support column 263 and the fourth support column 264 .

[0090] The positioning arm 23 is set between the connecting line of the third support column 263 and the fourth support column 264. In this way, after the engine is placed on the third support column 263 and the fourth support column 264, it is fixed by the positioning arm 23 to prevent the engine from easily falling off the third support column 263 and the fourth support column 264, thereby improving the reliability of the engine transfer device.

[0091] Alternatively, as Figure 2 As shown, the pallet rack 20 further includes a connecting column 271 and a U-shaped plate 272 . One end of the connecting column 271 is connected to the first supporting column 261 , and the other end of the connecting column 271 is connected to the second supporting column 262 .

[0092] like Figure 2 As shown, the first side 221 of the positioning plate 22 is connected to the U-shaped plate 272 , the connecting post 271 is located in the opening of the U-shaped plate 272 , and the U-shaped plate 272 is slidably disposed on the connecting post 271 .

[0093] In the above implementation, the connecting column 271 serves as a slide rail, the U-shaped plate 272 serves as a slide groove, and the U-shaped plate 272 is clamped outside the slide rail so that the U-shaped plate 272 can slide along the slide rail. The positioning plate 22 is connected to the U-shaped plate 272. Therefore, when the U-shaped plate slides, it can drive the positioning plate 22 to slide along the slide rail, thereby achieving the purpose of allowing the positioning plate 22 to slide along the slide rail.

[0094] The connecting column 271 is disposed between the first supporting column 261 and the second supporting column 262 , thereby preventing the U-shaped plate 272 from sliding off the end of the connecting column 271 .

[0095] Alternatively, as Figure 2 As shown, a buffer pad 265 is provided at one end of the first support column 261 away from the bottom plate 21, one end of the second support column 262 away from the bottom plate 21, one end of the third support column 263 away from the bottom plate 21 and one end of the fourth support column 264 away from the bottom plate 21.

[0096] For example, the cushion 265 may be a nylon block. Nylon has excellent self-lubrication and friction resistance, and using nylon as the cushion 265 can extend its service life. Furthermore, nylon has good elasticity, which can cushion the impact of the engine on the support column during installation and prevent friction with the engine casing, which could cause damage.

[0097] Alternatively, as Figure 2 As shown, the tray rack 20 also includes an L-shaped plate 28, which has a first plate body and a second plate body that are perpendicular to each other. The first plate body is located on the bottom plate 21, and the second plate body is provided with a third strip hole 281, and the length direction of the third strip hole 281 is parallel to the bottom plate 21.

[0098] The L-shaped plate 28 is located on a line connecting the third support column 263 and the fourth support column 264 , and the third support column 263 is located between the L-shaped plate 28 and the fourth support column 264 .

[0099] It should be noted that the L-shaped plate can also be set at different positions according to engines of different specifications, as long as it can be fixedly connected to the engine, and the embodiment of the present disclosure does not limit it.

[0100] In the disclosed embodiment, the third strip-shaped hole 281 is used for bolts to pass through. After passing through the third strip-shaped hole 281 , the bolts can be connected to the screw holes on the engine housing to fix the engine on the L-shaped plate 28 .

[0101] Among them, the third strip hole 281 is long and narrow, and the bolt can be inserted into any area of ​​the third strip hole 281 to meet the need of docking the bolt with the screw hole on the engine casing, thereby improving the adaptability of the positioning arm 23 and the engine.

[0102] Alternatively, as Figure 2 As shown, the bottom plate 21 is a square frame structure, and the middle portion of the bottom plate 21 is hollowed out, which can reduce the weight of the bottom plate 21 and achieve a lightweight design of the tray rack 20.

[0103] When using the engine transfer device provided by the embodiment of the present disclosure to fix the engine, first, at least one pallet rack 20 is fixed to the base 10; then, the positioning arm 23 on the pallet rack 20 is rotated to abut against the limiting baffle 25; then, the engine is placed on the four support columns; then, the positioning plate 22 is slid so that the first connecting structure on the positioning plate 22 can be opposite to the connecting structure on the engine casing, and the engine casing and the positioning plate 22 are fixed together with bolts; then, the positioning arm 23 is rotated so that the second connecting structure on the positioning arm 23 can be opposite to the connecting structure on the engine casing, and the engine casing and the positioning arm 23 are fixed together with bolts; then, the telescopic rod on the limiting baffle 25 is extended and retracted so that one end of the telescopic rod can abut against the positioning arm 23, so that the telescopic rod supports the positioning arm 23; finally, the engine casing and the L-shaped plate 28 are fixed together with bolts to fix the engine on the engine transfer device.

[0104] The above does not limit the present disclosure in any form. Although the present disclosure has been disclosed as above through the embodiments, it is not intended to limit the present disclosure. Any technician familiar with the profession can make slight changes or modifications to equivalent embodiments with equivalent changes using the technical content disclosed above without departing from the scope of the technical solution of the present disclosure. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
