Description

Technical Field

[0001] The utility model relates to the technical field of logistics packaging and transportation, and more specifically, to a placing device suitable for a crankshaft. Background Art

[0002] The crankshaft is an extremely important component in an automobile engine. It bears the force transmitted by the connecting rod and converts it into torque, which is output through the crankshaft to drive other accessories on the engine to work. As the main part of the engine, the qualification of the crankshaft determines whether the automobile engine can work properly, directly affecting the safety of the automobile. Therefore, the protection of the crankshaft is particularly important, especially the transportation packaging protection. After each qualified crankshaft finished product is taken off the production line, it needs to be uniformly placed into a special container. Since the shape of the crankshaft is relatively complex, there are relatively high requirements for the packaging for placing the crankshaft. The existing solutions generally use plastic trays to place the crankshaft. However, the shape of the plastic tray is generally designed according to the shape of the crankshaft and cannot match crankshafts of different shapes, so the versatility is relatively low. In addition, the gear ring of the crankshaft is prone to rubbing against the plastic tray, generating powdery foreign matters, thus affecting the quality of the crankshaft. Moreover, since the crankshaft belongs to a metal product and is prone to rusting, an anti-rust oil needs to be sprayed during storage. The plastic tray is designed according to the shape of the crankshaft and has a relatively complex shape. When the anti-rust oil on the crankshaft drips onto the plastic tray, it is difficult to clean the plastic tray, affecting the storage environment of the crankshaft.

[0003] There is an existing Chinese invention with a publication number of CN110294196A, which discloses a crankshaft packing box, including a box body. The distance between the front and rear inner walls of the box body is adapted to the length of the crankshaft. It also includes a plurality of layers of crankshaft support frames continuously and horizontally stacked in the box body. Each of the crankshaft support frames is composed of a strip-shaped bottom plate and a plurality of vertical plates uniformly arranged on the top surface of the bottom plate. The length of the bottom plate is adapted to the distance between the left and right inner walls of the box body. The plate surface of the vertical plate is perpendicular to the long direction of the bottom plate. The adjacent vertical plate surfaces and the top surface of the bottom plate enclose an upward-opening groove. The inner wall of the box body is provided with a positioning groove. There are two crankshaft support frames on each layer in the box body, and both ends of the crankshaft support frame are constrained in the positioning groove. The packing box of this invention is simple to manufacture; it is convenient to take and place the crankshaft, with convenient operation and high efficiency; the packing box has a better effect of protecting the crankshaft, and multiple crankshafts can be placed in the packing box, saving the packaging cost and transportation cost.

[0004] However, in the above technical solution, the two ends of the crankshaft are placed in the groove between the vertical plates. The groove does not match the shape of the crankshaft, and the gear ring on the crankshaft is prone to collide or rub against the groove wall of the groove, generating powdery foreign matters, thus affecting the quality of the crankshaft. Summary of the Utility Model

[0005] To solve the above problems, the present utility model provides a placement device suitable for a crankshaft. By placing the crankshaft in the U-shaped grooves of two placement plates, the position of the crankshaft can be fixed while facilitating taking and placing, and avoiding quality defects such as foreign objects caused by scratching of the crankshaft.

[0006] To solve the above technical problems, the technical solution adopted by the present utility model is: a placement device suitable for a crankshaft, including a frame plate and a placement plate. A plurality of the frame plates are provided, and the plurality of frame plates are connected in sequence to form a frame. At least two placement plates are provided, and the placement plates are arranged in parallel and installed in the frame. The two ends of the placement plate are respectively connected to the frame. A U-shaped groove for placing the crankshaft is provided on the placement plate, and the U-shaped grooves on two adjacent placement plates are arranged opposite to each other.

[0007] In the technical scheme, a plurality of frame plates are provided, and the plurality of frame plates are connected in sequence to form a frame, and the crankshaft is placed in the frame. The frame plate composed of the frame plates determines the basic shape of the device on the one hand, and protects the crankshaft placed in the frame on the other hand. When the device collides with the outside world, only the frame plate collides with the outside world, and does not collide with the crankshaft located in the frame. The placement plate is installed in the frame for holding the crankshaft. Both ends of the placement plate are connected to the frame, and the frame plate can fix the position of the placement plate. A U-shaped groove is provided on the placement plate, and the crankshaft is placed in the U-shaped groove. The bottom of the U-shaped groove is an arc, and is a structure with high sides and low middle. When the crankshaft is placed in the U-shaped groove, under the action of gravity, the crankshaft slides to the lowest point of the bottom of the U-shaped groove. When shaking occurs during transportation, the movement of the crankshaft in the U-shaped groove can only move to a higher place, and in this process, it is necessary to overcome its own gravity, thereby limiting the relative sliding of the U-shaped groove and the crankshaft, and playing a role in fixing the position of the crankshaft. When the shaking degree is too large and the crankshaft shakes out from the bottom of the U-shaped groove, the groove wall of the U-shaped groove can also contact the crankshaft to limit the displacement of the crankshaft. The U-shaped groove abuts against the crankshaft's journal. The center of the crankshaft is on the journal, and the U-shaped groove abuts against the crankshaft's journal to support the crankshaft, which can ensure the stability of the support. At the same time, the position of the journal is relatively fixed, so that the U-shaped groove can be suitable for different types of crankshafts. The depth of the U-shaped groove is shallow and the width of the placement plate. When the crankshaft is placed in the U-shaped groove, the crankshaft is in an overhead state except for the part that abuts against the U-shaped groove. On the one hand, the device does not need to be specially set up to adapt to different types of crankshafts. On the other hand, the overhead crankshaft will not collide with any structure of the device. Therefore, there is no problem of the gear ring on the crankshaft colliding with the groove wall of the groove, scratching, producing powdery foreign matter, and affecting the quality of the crankshaft. The U-shaped groove is at a certain distance from the place where the placement plate and the frame plate are connected. This arrangement allows for free space near the U-shaped groove. On the one hand, the space can be used to place the crankshaft. On the other hand, the space is convenient for a person's hand or a taking device to reach in when the crankshaft needs to be taken. Both the frame plate and the placement plate are plate-like structures with simple structures. On the one hand, they are easy to manufacture and reduce production costs. On the other hand, since the crankshaft needs to be coated with anti-rust oil, the anti-rust oil is easy to contaminate the device, and the simpler structure is easy to clean. The journals on the crankshaft are divided into multiple independent small sections, and at least two U-shaped grooves on the placement plates can support the journals located in different sections, making the journals placed in the U-shaped grooves more stable. The journals of different sections on the same crankshaft are coaxial, so the abutment grooves on the placement plates that abut the journals do not require additional design and are universal.

[0008] Preferably, a plurality of U-shaped grooves are provided along the length direction of the placement plate.

[0009] Preferably, the frame plate is detachably connected to the placement plate.

[0010] Preferably, a first slot is formed in the frame plate, and a second slot is formed in the placing plate, and the first slot is inserted into the second slot.

[0011] Preferably, a first mounting hole is provided on the frame plate on the side of the first slot, and a second mounting hole is provided on the placing plate on the side of the second slot.

[0012] Preferably, a handle is provided on the placing plate, the opening of the second slot faces upward, and the opening of the first slot of the frame plate connected to the placing plate faces downward.

[0013] Preferably, one of the two connected frame plates is provided with a third slot at the connection, and the other frame plate is provided with a fourth slot at the connection, and the third slot is inserted into the fourth slot.

[0014] Preferably, third mounting holes are provided on the frame plate beside the third slot and the fourth slot.

[0015] Preferably, it further includes a support plate connecting the placing plates, both ends of the support plate are connected to the frame plates on its opposite sides, the middle of the support plate is connected to each placing plate, and the support plate is perpendicular to the placing plate.

[0016] Preferably, a fifth slot is provided on the support plate, a plurality of the fifth slots are arranged along the length direction of the support plate, and each fifth slot is respectively inserted into a sixth slot formed in the placing plate and a seventh slot formed in the frame plate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, the frame plates are connected in sequence to form a frame, and the crankshaft is placed in the frame, and the frame plates play a protective role for the internal crankshaft. A U-shaped groove is provided on the placing plate, and the crankshaft is placed in the U-shaped groove, and the position of the crankshaft can be fixed. The bottom of the U-shaped groove is arc-shaped, with a structure that is high on both sides and low in the middle, and the self-gravity of the crankshaft can be used to limit its movement. Except for the part where the journal of the crankshaft abuts against the U-shaped groove, other parts of the crankshaft are suspended, and there is no problem that the toothed ring on the crankshaft collides with the groove wall of the groove, causing scraping and generating powdery foreign matters, which affect the quality of the crankshaft. At the same time, the position of the journal of the crankshaft is relatively fixed. The U-shaped groove only abuts against the journal while other parts of the crankshaft are suspended, so the design of the U-shaped groove does not need to consider other structures except the journal of the crankshaft, improving the versatility of the device. The placing plate and the frame plate are plate-shaped structures, and the device is composed of the combination of the placing plate and the frame plate. The structure is simple, easy to clean the rust-proof oil adhered to it, and easy to produce. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the attached drawings:

[0024] Embodiment 1

[0025] As Figure 1As shown, a placement device suitable for a crankshaft includes a frame plate 1 and a placement plate 2. The frame plate 1 is provided with multiple frames, and multiple frame plates 1 are connected in sequence to form a frame. At least two placement plates 2 are provided, and each placement plate 2 is arranged in parallel and installed in the frame. The two ends of the placement plate 2 are respectively connected to the frame. The placement plate 2 is provided with a U-shaped groove 21 for placing the crankshaft, and the U-shaped grooves 21 on two adjacent placement plates 2 are arranged oppositely. There are multiple frame plates 1, and multiple frame plates 1 are connected in sequence to form a frame, and the crankshaft is placed in the frame. The frame plate 1 composed of the frame plates 1 determines the basic shape of the device on the one hand, and on the other hand, it protects the crankshaft placed in the frame. When the device collides with the outside world, only the frame plate 1 collides with the outside world, and will not collide with the crankshaft located in the frame. The placement plate 2 is installed in the frame for holding the crankshaft. The two ends of the placement plate 2 are connected to the frame, and the frame plate 1 can fix the position of the placement plate 2. The placement plate 2 is provided with a U-shaped groove 21, and the crankshaft is placed in the U-shaped groove 21. The bottom of the U-shaped groove 21 is arc-shaped, and is a structure with high sides and low middle. When the crankshaft is placed in the U-shaped groove 21, under the action of gravity, the crankshaft slides to the lowest point of the bottom of the U-shaped groove 21. When shaking occurs during transportation, the movement of the crankshaft in the U-shaped groove 21 can only move to a higher place. In this process, it is necessary to overcome its own gravity, thereby limiting the relative sliding of the U-shaped groove 21 and the crankshaft, and playing a role in fixing the position of the crankshaft. When the degree of shaking is too large and the crankshaft shakes out from the bottom of the U-shaped groove 21, the groove wall of the U-shaped groove 21 can also contact the crankshaft to limit the displacement of the crankshaft. The U-shaped groove 21 is in contact with the journal of the crankshaft. The center of the crankshaft is on the journal, and the U-shaped groove 21 is in contact with the journal of the crankshaft to support the crankshaft, which can ensure the stability of the support. At the same time, the position of the journal is relatively fixed, so that the U-shaped groove 21 can be applied to different types of crankshafts. The depth of the U-shaped groove 21 is shallow and the width of the placement plate 2. When the crankshaft is placed in the U-shaped groove 21, the crankshaft is in an overhead state except for the part that abuts against the U-shaped groove 21. On the one hand, the device does not need to be specially set in shape to adapt to different types of crankshafts. On the other hand, the overhead crankshaft will not collide with any structure of the device. Therefore, there is no problem of the gear ring on the crankshaft colliding with the groove wall of the groove, scratching, and producing powdery foreign matter, which affects the quality of the crankshaft. The U-shaped groove 21 is a certain distance away from the connection between the placement plate 2 and the frame plate 1. This arrangement allows there to be free space near the U-shaped groove 21. On the one hand, the space can be used to place the crankshaft. On the other hand, when the crankshaft needs to be taken, the space is convenient for human hands or taking devices to reach in. Both the frame plate 1 and the placement plate 2 are plate-like structures with simple structures. On the one hand, they are easy to manufacture and reduce production costs. On the other hand, since the crankshaft needs to be coated with anti-rust oil, the anti-rust oil is easy to contaminate the device, and the simpler structure is easy to clean.The journal on the crankshaft is divided into multiple independent small segments. There are at least two U-shaped grooves 21 on the placement plate 2 that can support the journals in different segments, making the journals placed in the U-shaped grooves 21 more stable. The journals in different segments on the same crankshaft are coaxial. Therefore, the abutting grooves 21 on the placement plate 2 that abut against the journals do not require additional design and have universality.

[0026] As Figure 1 shown, multiple U-shaped grooves 21 are arranged along the length direction of the placement plate 21. Each U-shaped groove is used to place a single crankshaft. Arranging multiple U-shaped grooves 21 along the length direction of the placement plate 21 can be used to place multiple crankshafts, improving the storage capacity of the device.

[0027] As Figure 1 shown, the frame plate 1 is detachably connected to the placement plate 2. On the one hand, when the device is not needed, the frame plate 1 and the placement plate 2 can be disassembled and stacked to save space. On the other hand, when cleaning, the frame plate 1 and the placement plate 2 can be disassembled to facilitate washing off the anti-rust oil stained on the frame plate 1 and the placement plate 2. At the same time, the detachable connection between the frame plate 1 and the placement plate 2 also facilitates the replacement of the frame plate 1 or the placement plate 2. When the frame plate 1 or the placement plate 2 is damaged, only the corresponding component needs to be replaced, and there is no need to replace the whole device, which is beneficial to reducing the use cost.

[0028] As Figure 2 shown, a first slot 11 is opened on the frame plate 1, and a second slot 22 is opened on the placement plate 2. The first slot 11 and the second slot 22 are inserted into each other. After the first slot 11 and the second slot 22 are inserted into each other, the slot wall of the first slot 11 abuts against the two opposite surfaces of the placement plate 2, restricting the relative movement between the frame plate 1 and the placement plate 2 in the length direction of the frame plate 1. The second slot 22 abuts against the two opposite surfaces of the frame plate 1, restricting the relative movement between the frame plate 1 and the placement plate 2 in the length direction of the placement plate 2. The connected frame plate 1 and the placement plate 2 are perpendicular to each other. The relative movement in any direction on the plane can be decomposed into the movement in the length direction of the frame plate 1 and the movement in the length direction of the placement plate 2. Therefore, after the first slot 11 and the second slot 22 are inserted into each other, the relative movement between the frame plate 1 and the placement plate 2 on the plane can be completely restricted. Similarly, the first slots 11 on different frame plates 1 can be inserted into each other to restrict the movement of different frame plates 1 in the plane direction.

[0029] As Figure 1As shown, a first mounting hole 12 is provided on the frame plate 1 on the side of the first slot 11, and a second mounting hole 25 is provided on the placing plate 2 on the side of the second slot 22. The first slot 11 and the second slot 22 can only restrict the relative movement of the frame plate 1 and the placing plate 2 in their respective length directions, and cannot restrict the mutual extraction between the first slot 11 and the second slot 22. Therefore, a first mounting hole 12 and a second mounting hole 25 need to be provided beside the first slot 11 and the second slot 22 respectively. After the first slot 11 and the second slot 22 are inserted into each other, use a cable tie or a rope to pass through the first mounting hole 12 provided beside the first slot 11 and the second mounting hole 25 provided beside the second slot 22 in sequence and then tie them up, thereby realizing the fixation of the frame plate 1 and the placing plate 2, so that the first slot 11 and the second slot 22 cannot be extracted from each other. When disassembly is required, only need to cut the rope or cable tie that binds the first mounting hole 12 and the second mounting hole 25.

[0030] Embodiment 2

[0031] This embodiment is similar to the above Embodiment 1, the difference is that, as Figure 2 shown, a handle 23 is provided on the placing plate 2, the notch of the second slot 22 faces upward, and the notch of the first slot 11 of the frame plate 1 connected to the placing plate 2 faces downward. When the crankshaft needs to be carried, it can be hoisted by a crane after passing a rope through the handle 23. When hoisting, the direction of the gravity received by the frame plate 11 is exactly the direction inside the second slot 22. Under the action of its own gravity, the first slot 11 of the frame plate 1 will be inserted into the second slot 22 more firmly, ensuring the stability of the connection between the frame plate 1 and the placing plate 2 during handling.

[0032] As Figure 2 shown, on one of the two connected frame plates 1, a third slot 13 is provided at the connection, and on the other frame plate 1, a fourth slot 14 is provided at the connection, and the third slot 13 and the fourth slot 14 are plugged into each other. The two connected frame plates 1 are connected through the third slot 13 and the fourth slot 14, which is easy to disassemble. When finally disassembled, the frame will be completely disassembled into multiple independent frame plates 1, which is easy to store and clean.

[0033] As Figure 2 shown, third mounting holes 15 are provided on the frame plate 1 beside the third slot 13 and the fourth slot 14. After the third slot 13 and the fourth slot 14 are plugged into each other, it is possible to use a cable tie or a rope to pass through the third mounting holes 15 located on different frame plates 1 in sequence and then tie them up to ensure that the mutually plugged third slot 13 and fourth slot 14 will not separate from each other.

[0034] Embodiment 3

[0035] This embodiment is similar to the above Embodiment 1, the difference is that, asFigure 1 As shown, it further includes a support plate 3 connecting each placement plate 2. Both ends of the support plate 3 are connected to the frame, the middle part of the support plate 3 is connected to each placement plate 2, and the support plate 3 is perpendicular to the placement plate 2. Since the placement plate 2 is a long strip-shaped plate structure, only both ends of the placement plate 2 are connected to the frame plate 1, and the middle part lacks support. Therefore, the middle part of the placement plate 2 is prone to bending deformation along the length direction, resulting in the deviation of the position of the U-shaped groove 22 on the placement plate 2, and the crankshaft cannot be placed. Therefore, it is also necessary to set the support plate 3. Both ends of the support plate 3 are connected to the frame to fix the position of the support plate 3. The middle part of the support plate 3 is connected to the placement plate 2, and the support plate 3 is perpendicular to the placement plate 2. When the placement plate 2 bends, the bending direction is the same as the length direction of the support plate 3, and the placement plate 2 is supported by the support plate 3 and is difficult to bend.

[0036] As Figure 2 shown, a fifth slot 31 is provided on the support plate 3. A plurality of fifth slots 31 are arranged along the length direction of the support plate 3. Each fifth slot 31 is respectively inserted into a sixth slot 24 opened on the placement plate 2 and a seventh slot 16 opened on the frame plate 1. The fifth slots 31 at both ends of the support plate 3 and the seventh slots 16 on the frame plate 1 are inserted into each other to fix the position of the support plate 3. The fifth slots 31 in the middle of the support plate 3 and the sixth slots 24 on the placement plate 2 are inserted into each other to fix the position of the placement plate 2 and prevent it from deflecting. The fifth slot 31 and the sixth slot 24 and the seventh slot 16 are connected by insertion, which is easy to disassemble.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
