Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] Please refer to Figure 1 and Figure 2 As shown in the figure, the crankshaft packaging apparatus according to an embodiment of the present utility model includes a main frame 100, a plurality of support columns 200, and a support disk 300. The main frame 100 is provided with a plurality of fixed seats 110. Among them, the main frame 100 serves as the load-bearing body of the crankshaft packaging apparatus, and it can be made of metal materials with relatively high strength such as steel and iron. The main frame 100 can protect the support disk 300 and the crankshaft 10 placed therein from being squeezed or collided, and improve the safety of the crankshaft 10 during transportation.

[0048] As Figure 2As shown, in one embodiment, the main frame 100 can be rectangular. For example, the main frame 100 can include four main beams 120, and the four main beams 120 are connected end to end in sequence to form a rectangular ring structure. The main frame 100 can further include a plurality of support beams, and the plurality of support beams can be connected between any two opposite main beams 120. The main frame 100 can further include a bottom plate 130, and the bottom plate 130 is fixed above the plurality of support beams.

[0049] As Figure 1 shown, the number of the fixing seats 110 can be four, and the four fixing seats 110 are correspondingly arranged at the four corners of the main frame 100.

[0050] It can be understood that in other embodiments, the main frame 100 can also be circular or polygonal in shape, etc. The plurality of fixing seats 110 can be arranged at intervals along the circumference of the main frame 100.

[0051] Referring to Figure 1 , in the embodiments of the present application, a plurality of support columns 200 are arranged above the main frame 100. The bottom ends of the respective support columns 200 are rotatably connected to the corresponding fixing seats 110. Each support column 200 can be in an upright position relative to the main frame 100 or can be rotated inward to be folded on the main frame 100.

[0052] In one embodiment, the number of the support columns 200 can be four, and the four support columns 200 are rotatably connected to the four fixing seats 110 correspondingly. As Figure 1 shown, when each support column 200 is in an upright position relative to the main frame 100, the plurality of support columns 200 can enclose a loading space with a certain height above the main frame 100, so as to facilitate loading the support disk 300 and the crankshaft 10 on the support disk 300. It can be understood that the height of the loading space formed by the plurality of support columns 200 should be greater than the overall height of the loaded objects therein.

[0053] As Figure 3 shown, when each support column 200 is rotated inward relative to the main frame 100 and folded on the main frame 100, it is convenient for loading and unloading the crankshaft 10; and after the support columns 200 are folded, the overall height of the packaging appliance is reduced, which is convenient for the storage of the packaging appliance and reduces the storage space occupied by the packaging appliance.

[0054] Referring to Figure 3 , the connection manner between each support column 200 and each fixing seat 110 can be: a receiving groove 111 for limiting and receiving the bottom end of the support column 200 is formed on the fixing seat 110, and the receiving groove 111 has an opening. The support column 200 can be turned inward through the opening to be folded on the main frame 100.

[0055] Moreover, a connecting through-hole 210 is formed at the bottom end of the supporting column 200. The connecting through-hole 210 is an elongated hole extending along the length direction of the supporting column 200. A through-hole corresponding to the connecting through-hole 210 is provided on the fixing base 110. By using a suitable fastener to pass through the connecting through-hole 210 and the through-hole, the rotatable connection of the supporting column 200 relative to the fixing base 110 can be achieved. Among them, the fastener can be a bolt or a pin, etc.

[0056] As Figure 1 and Figure 3 shown, a limiting block 220 is further provided on the supporting column 200, and a clamping groove 112 corresponding to the limiting block 220 is provided at the top end of the fixing base 110. When the supporting column 200 is in an upright position relative to the main frame 100, the limiting block 220 is clamped in the clamping groove 112. By setting the cooperation between the limiting block 220 and the clamping groove 112, the relative displacement of the supporting column 200 in the horizontal direction can be limited, ensuring that the supporting column 200 is in a stable upright working state.

[0057] It can be understood that when the crankshaft packaging appliance is used up and the supporting column 200 needs to be folded, only need to lift the supporting column 200 by a certain distance so that the limiting block 220 is disengaged from the clamping groove 112, so that the supporting column 200 can be turned inward and folded on the main frame 100.

[0058] See Figure 1 shown, in some embodiments, a guiding cone 230 can be provided at the top end of each supporting column 200, and a guiding sleeve 113 adapted to be sleeved outside the guiding cone 230 is formed at the bottom end of each fixing base 110. The outer dimension of the guiding cone 230 is adapted to the inner cavity shape and dimension of the guiding sleeve 113, so that the inner cavity of the guiding sleeve 113 can accommodate the guiding cone 230. When each crankshaft packaging appliance is in a state where the supporting column 200 is in an upright position, through the cooperation of the guiding cone 230 and the guiding sleeve 113, the stacking of multiple packaging appliances in multiple use states can be realized.

[0059] As Figure 3 shown, the outer dimension of the top end of the fixing base 110 can be adapted to the inner cavity shape and dimension of the guiding sleeve 113. When each crankshaft packaging appliance is in a state where the supporting column 200 is folded inward, through the cooperation of the guiding sleeve 113 and the top end of the fixing base 110, the stacking of multiple packaging appliances in a folded state can be realized.

[0060] Therefore, by providing the guiding cone 230, it is convenient to stack multiple packaging appliances, reduce the floor area, and facilitate the storage and placement of the packaging appliances.

[0061] It can be understood that the positions of the guiding vertebral body 230 and the guiding sleeve 113 can also be interchanged. For example, the guiding vertebral body 230 can be arranged at the bottom end of the fixed seat 110, and the guiding sleeve 113 can be arranged at the top end of the supporting column 200. As long as the cooperation of the guiding vertebral body 230 and the guiding sleeve 113 can achieve the purpose of stacking multiple packaging appliances.

[0062] See Figure 1 , in one embodiment, the crankshaft packaging appliance further includes a chassis 140, and the chassis 140 is arranged at the bottom of the main frame 100. Wherein, the number of the chassis 140 can be two or more, and the arrangement of multiple chassis 140 can ensure the stable placement of the packaging appliance.

[0063] Preferably, the bottom end of the chassis 140 can be lower than the bottom ends of the fixed seats 110. When the packaging appliance is placed on the crankshaft production line, the chassis 140 at the bottom of the main frame 100 can be clamped between two transmission rollers of the production line, ensuring that the packaging appliance can be positioned and fixed at the current position on the production line, facilitating the grasping and hoisting of the crankshaft.

[0064] Wherein, the chassis 140 can also be provided with forklift holes for the forklift forks to extend into. The forklift lifting and transfer of the packaging appliance can also be realized through the chassis 140, facilitating the transportation and use of the packaging appliance.

[0065] See Figure 2 , in the embodiment of the present application, the support plate 300 is mainly used to stably support and place the crankshaft 10. Specifically, the support plate 300 is arranged inside the main frame 100. Wherein, the support plate 300 can be made of materials such as plastic, which is beneficial to reducing the weight of the packaging appliance and lowering the cost.

[0066] Such as Figure 2 shown, the outer contour of the support plate 300 can be rectangular to be adapted to be fixed inside the main frame 100. Wherein, the support plate 300 can be limit-mounted inside the main frame 100. For example, the support plate 300 can be limit-placed on the bottom plate 130 of the main frame 100.

[0067] Such as Figure 2 shown, in one embodiment, the bottom plate 130 can be provided with limit plates 131 for limit-fixing the support plate 300. The number of the limit plates 113 can be four. The four limit plates 113 can be respectively fixed on the bottom plate 130 corresponding to the four corner positions of the support plate 300. Wherein, the limit plate 113 can be an L-shaped structure. Through each limit plate 113, the position of the support plate 300 inside the main frame 100 can be limited, so that the support plate 300 is relatively fixedly arranged on the main frame 100.

[0068] When the support plate 300 is in use, the crankshaft 10 is placed inside the support plate 300. Under the action of the gravity of the crankshaft 10 itself, the support plate 300 is pressed and fixed on the main frame 100. At the same time, due to the limiting effect of the limiting block 220, the possibility of the horizontal sliding of the support plate 300 is eliminated. Thus, the support plate 300 can be reliably fixed on the main frame 100 to better stably support the crankshaft 10.

[0069] It can be understood that in other embodiments, the support plate 300 can also be detachably connected to the main frame 100. Or, the support plate 300 can also be fixedly connected to the main frame 100.

[0070] See Figure 4 , in one embodiment, in the axial direction of the crankshaft 10, the length of the support plate 300 is less than the length of the main frame 100. When the support plate 300 is placed inside the main frame 100, there is a relatively large gap between the two side edges of the support plate 300 in the axial direction of the crankshaft 10 and the corresponding two side edges of the main frame 100.

[0071] Among them, the length of the main frame 100 matches the length dimension of the crankshaft 10. When the crankshaft 10 is placed on the support plate 300 and the support plate 300 is placed inside the main frame 100, since the length of the main frame 100 matches the length dimension of the crankshaft 10, the two ends of the crankshaft 10 are close to the two side edges of the main frame 100 in the axial direction of the crankshaft 10. And since the length of the support plate 300 in the axial direction of the crankshaft 10 is less than the length of the main frame 100, the two ends of the crankshaft 10 can respectively protrude from the two side edges of the support plate 300. Thus, when placing and grasping the crankshaft 10, the external grasping device can extend into the gap between the support plate 300 and the main frame 100 to release or grasp the end of the crankshaft 10, facilitating the placement and hoisting of the crankshaft 10.

[0072] See Figure 5 and Figure 6 , in this application, the support plate 300 includes two support portions 310 arranged at a relative interval. Corresponding positioning grooves 311 opening upward are respectively provided on the two support portions 310. The positioning grooves 311 are used to receive the end journals of the crankshaft 10.

[0073] Specifically, the support plate 300 may include a rectangular chassis 320, and the two support portions 310 are respectively located at the relative two side edges of the chassis 320. Among them, the support portion 310 can be a long strip-shaped block structure protruding upward from the side of the chassis 320.

[0074] The positioning groove 311 can be formed by the downward depression of the upper surface of the support portion 310. As Figure 5As shown, in one embodiment, the positioning groove 311 is an arc-shaped groove. The concave surface of the positioning groove 311 is an arc surface that matches the outer peripheral surface of the end journal of the crankshaft 10. When the end journal of the crankshaft 10 is placed in the positioning groove 311, the concave surface of the positioning groove 311 fits against the outer peripheral surface of the end journal, and the positioning groove 311 can reliably fix the end journal of the crankshaft 10 to prevent the crankshaft 10 from shaking.

[0075] In other embodiments, the positioning groove 311 can also be a V-shaped groove or a U-shaped groove.

[0076] As Figure 5 shown, in one embodiment, a cushion block 330 is provided in the positioning groove 311. Among them, the cushion block 330 can be made of wear-resistant materials such as polyurethane. The shape of the cushion block 330 can be adapted to the end journal part of the crankshaft 10. The cushion block 330 can be detachably connected to the support disk 300.

[0077] By providing the cushion block 330 in the positioning groove 311, the direct contact between the end journal of the crankshaft 10 and the support disk 300 can be separated, preventing the support disk 300 from generating chips due to friction, which is beneficial to maintaining the surface cleanliness of the crankshaft 10 and extending the service life of the support disk 300; and the end journal of the crankshaft 10 can be better protected by the cushion block 330, reducing the wear of the end journal caused by friction and collision.

[0078] See Figure 6 shown, the number of positioning grooves 311 on each support portion 310 can be multiple. For example, four positioning grooves 311 can be provided on each support portion 310. There are a total of eight positioning grooves 311 on the two support portions 310. The eight positioning grooves 311 are arranged in pairs. Therefore, the support disk 300 can be used to place four crankshafts 10.

[0079] It should be noted that the distance between two adjacent positioning grooves 311 on each support portion 310 is such that the adjacent two crankshafts 10 placed on the support disk 300 do not touch each other.

[0080] See Figure 6 , the support disk 300 is provided with a plurality of support grooves 321 opening upward, and the plurality of support grooves 321 are arranged at intervals along the axial direction of the crankshaft 10 between the corresponding positioning grooves 311 of the two support portions 310. As Figure 6 shown, between any two corresponding positioning grooves 311, a plurality of support grooves 321 are respectively provided on the chassis 320. Each support groove 321 is respectively used to receive the fan blades of the crankshaft 10.

[0081] As Figure 6As shown, in one embodiment, each support groove 321 is tapered in the vertically upward direction. Since the support groove 321 is wider at the top and narrower at the bottom, the crankshaft 10 can be more stably supported within the support groove 321 under its own gravity.

[0082] As Figure 6 shown, in one embodiment, a cushion block 330 is provided in each support groove 321. Among them, the cushion block 330 can be made of wear-resistant materials such as polyurethane. The cushion block 330 can be a rectangular block structure. The cushion block 330 can be detachably connected to the support disk 300.

[0083] By providing the cushion block 330 in the support groove 321, the direct contact between the fan blades of the crankshaft 10 and the support disk 300 can be separated, avoiding the generation of chips due to friction on the support disk 300, which is beneficial to maintaining the surface cleanliness of the crankshaft 10 and extending the service life of the support disk 300. And the cushion block 330 can play a role in buffering the impact generated by the crankshaft 10 being jolted during transportation to a certain extent.

[0084] As Figure 5 shown, when the crankshaft 10 is placed on the support disk 300, the end journals at both ends of the crankshaft 10 are respectively received by two corresponding positioning grooves 311 on the two support portions 310, and each fan blade of the crankshaft 10 is received by each support groove 321. The crankshaft 10 can be effectively positioned and supported through the positioning grooves 311 and the support grooves 321, so that the crankshaft 10 can be stably placed on the support disk 300 under its own gravity, and thus the crankshaft 10 is not easily damaged during transportation and storage.

[0085] Since the positioning grooves 311 are in contact with the outer peripheries of the end journals at both ends of the crankshaft 10, and each support groove 321 is in contact with the outer peripheries of the fan blades of the crankshaft 10, the main journal and connecting rod journal and other parts between the fan blades can be prevented from contacting the support disk 300, so as to better protect the crankshaft 10 from being damaged during transportation and storage.

[0086] See Figure 1 and Figure 2 shown, in one embodiment, the crankshaft packaging device further includes a protective cover 400. The protective cover 400 is used to cover above the support disk 300, and an accommodation space for accommodating the crankshaft 10 is formed between the protective cover 400 and the support disk 300. Among them, the protective cover 400 can be made of materials such as hard plastic. By providing the protective cover 400, when the crankshaft 10 is placed on the support disk 300, the protective cover 400 is covered above the crankshaft 10, thereby further playing a role in protecting the crankshaft 10 and preventing the crankshaft 10 from being damaged by extrusion or collision during transportation. At the same time, the protective cover 400 can also play a role in dust prevention and dirt prevention.

[0087] Specifically, the surface of the protective cover 400 facing the support plate 300 is used to contact the crankshaft 10. It can be understood that the surface of the protective cover 400 facing the support plate 300 may be provided with grooves or protrusion structures corresponding to various parts of the crankshaft 10 to better fit the placement of the crankshaft 10. In addition, a cushion block structure may be provided on the surface of the protective cover 400 facing the support plate 300. Specifically, cushion blocks may be provided at the positions where the protective cover 400 contacts various parts of the crankshaft 10 to separate the direct contact between the crankshaft 10 and the protective cover 400, avoid the generation of chips by the protective cover 400, thereby facilitating the maintenance of the surface cleanliness of the crankshaft 10 and prolonging the service life of the protective cover 400.

[0088] As Figure 1 and Figure 2 shown, a lashing groove 410 is provided on the surface of the protective cover 400 facing away from the support plate 300. The lashing groove 410 is used to limit the lashing member 20, so as to fix the protective cover 400 relative to the main frame 100 by using the lashing member 20. Among them, the lashing member 20 can be a strap, a rope, etc. A fixing ring for fixing the lashing member 20 may be provided on the main frame 100. By providing the lashing groove 410, the protective cover 400 can be bound relative to the main frame 100 by using the lashing member 20, thereby effectively preventing the crankshaft 10 from bouncing due to bumps during transportation and avoiding damage to the crankshaft 10.

[0089] See Figure 1 and Figure 3 , in one embodiment, the crankshaft packaging device further includes a plurality of protective plates 500, and each protective plate 500 is detachably connected between two adjacent support columns 200. When the support columns 200 are in a vertical position relative to the main frame 100, the plurality of protective plates 500 surround the outer periphery of the support plate 300.

[0090] Among them, the protective plate 500 can be detachably connected between the two support columns 200 in various detachable ways. As Figure 3 shown, for example, fixing plates 114 can be provided on two adjacent fixing seats 110 or two adjacent support columns 200. The fixing plate 114 can form a slot with the fixing seat 100, or the fixing plate 114 can form a slot with the support column 200. Each protective plate 500 can be inserted into the slot to realize detachable connection between two adjacent support columns 200. Alternatively, the protective plate 500 can also be detachably fixed between the two support columns 200 by means of bolt connection.

[0091] In this embodiment, when the support column 200 is erected relative to the main frame 100, each protective plate 500 can be connected between two adjacent support columns 200. Thus, the protective plate 500 can protect the crankshaft 10, preventing the crankshaft 10 from being damaged due to extrusion or collision during transportation. At the same time, the protective plate 500 can also prevent dust and dirt.

[0092] It can be understood that when the support column 200 needs to be folded, each protective plate 500 can be removed first, and then each support column 200 can be rotated for folding.

[0093] See Figure 3 , in one embodiment, an anti-collision block 240 is further provided at the top of the support column 200. When the support column 200 is folded inward on the main frame 100, the anti-collision block 240 can abut against the upper surface of the main frame 100 to buffer the impact force between the support column 200 and the main frame 100, preventing the support column 200 and the fixing plate 114 provided thereon from being damaged.

[0094] The crankshaft packaging device of the embodiment of the present utility model has at least the following beneficial effects:

[0095] By providing the main frame 100, it has a simple structure and high structural strength, which is beneficial to improving the safety of packaging and transportation of the crankshaft 10. By providing the support disk 300, and the support disk 300 is provided with a positioning groove 311 and a support groove 321, the crankshaft 10 can be stably supported, preventing the crankshaft 10 from shaking and colliding during transportation, and increasing the safety of crankshaft transportation. The structure of the crankshaft packaging device is simple and durable, and it can be reused, effectively reducing the packaging and transportation costs; and the crankshaft packaging device can effectively protect the crankshaft 10, preventing the crankshaft 10 from being damaged due to extrusion or collision during transportation.

[0096] By making the length of the support disk 300 in the axial direction of the crankshaft 10 less than the length of the main frame 100, both ends of the crankshaft 10 can respectively protrude from the two side edges of the support disk 300. Thus, when placing and grasping the crankshaft 10, an external grasping device can extend into the gap between the support disk 300 and the main frame 100 to release or grasp the end of the crankshaft 10, facilitating the placement and hoisting of the crankshaft 10.

[0097] By providing the protective cover 400, when the crankshaft 10 is placed on the support disk 300, the protective cover 400 is covered above the crankshaft 10, further protecting the crankshaft 10, preventing the crankshaft 10 from being damaged due to extrusion or collision during transportation. At the same time, the protective cover 400 can also prevent dust and dirt.

[0098] The protective plate 500 can protect the crankshaft 10 and prevent the crankshaft 10 from being squeezed or collided during transportation and from being damaged. The protective plate 500 can also prevent dust and dirt.

[0099] Through the rotational connection between the support column 200 and the fixing seat 110, the support column 200 can be erected relative to the main frame 100 to load the support plate 300 and the crankshaft 10, which is convenient for packaging and transportation of the crankshaft 10. Alternatively, the support column 200 can be rotated inwardly to be folded on the main frame 100, so as to facilitate the loading and unloading of the support plate 300 and the crankshaft 10. In addition, when the packaging device is unloaded, folding the support column 200 can greatly reduce the volume of the packaging device, facilitate the storage of the packaging device, and reduce the storage space occupied by the packaging device.

[0100] By arranging the guide sleeve 113 at the bottom end of the fixing seat 110 and the guide cone 230 at the top end of the supporting column 200, multiple packaging tools can be stacked to reduce the floor space and facilitate the storage and accumulation of packaging tools.

[0101] By providing the base frame 140, the packaging device can be conveniently positioned and fixed on the crankshaft production line, and the packaging device can be lifted and transported by a forklift.

[0102] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0103] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
