Description

Technical Field

[0001] This utility model belongs to the field of crankshaft handling technology, and in particular relates to a crankshaft handling bracket. Background Technology

[0002] The crankshaft is a core component of an engine, used to convert the reciprocating motion of the piston into rotational motion, outputting power to drive other accessories. After its production and processing are completed, a bracket is needed to place it and facilitate the overall handling of multiple crankshafts for storage or packaging.

[0003] Chinese patent CN221395005U discloses a transplanting device for forestry afforestation. The patent describes "a crankshaft-specific transfer support frame, comprising a square platform with several support legs fixed to its bottom, supporting the platform. Symmetrically arranged support components are placed on the top of the platform, and lifting lugs are installed at the four corners of the top of the platform. The structure of a single support component includes a wave-shaped mounting frame with several first V-shaped surfaces on its end face. Several V-shaped plates are fixed to one side of the mounting frame, arranged along the length of the mounting frame and corresponding to the first V-shaped surfaces. A second V-shaped surface is provided on each V-shaped plate, and the support component supports the crankshaft through the second V-shaped surfaces. By setting up the support components and lifting lugs, the transfer support frame can temporarily store and transfer the crankshaft, effectively improving transfer efficiency. Furthermore, the transfer support frame is made of stainless steel, which is less prone to generating debris, ensuring the processing efficiency and quality of the crankshaft."

[0004] However, the above solution is inconvenient for the secure placement of crankshafts of different lengths and diameters. Crankshafts of different specifications have different lengths and diameters, and V-shaped plates with fixed spacing and fixed height are difficult to use for placing different crankshafts, which is not conducive to the handling of different crankshafts and results in low applicability. Therefore, it is necessary to design a crankshaft handling bracket. Utility Model Content

[0006] The present utility model is realized as follows. A crankshaft handling bracket includes a support plate; fixed cylinders fixedly connected to the four corners at the bottom end of the support plate, with a sliding plate slidably connected inside the fixed cylinders and extending outside the fixed cylinders; an adjusting component assembled on the fixed cylinders, and the adjusting component is used to limit and fix the sliding plate after sliding; fixing grooves equally spacedly opened at the top end of the support plate, a clamping groove is opened at the top end of the support plate on one side of the fixing groove, a sliding rod is fixedly connected to the inner wall of the fixing groove, a slider is movably connected to the surface of the sliding rod, a support plate is fixedly connected to the top end of the slider, a fixing plate is fixedly connected to the lower end on one side of the support plate, a threaded rod passing through the fixing plate is threadedly connected to the top end of the fixing plate, and a rubber block is rotatably connected to the bottom end of the threaded rod; a reserved groove opened at the top end of the support plate, a bolt hole is opened at the upper end of the inner wall of the reserved groove, a lifting plate extending outside the support plate is movably connected inside the reserved groove, through holes penetrating the lifting plate are equally spacedly opened on the lifting plate, a V-shaped plate is fixedly connected to the top end of the lifting plate, and a fixing bolt passing through the through holes and threadedly engaged with the inside of the bolt hole is movably connected to the upper end on one side of the support plate.

[0007] Preferably, an anti-slip rubber pad is fixedly connected to the inner wall of the V-shaped plate, and the shape of the anti-slip rubber pad is V-shaped.

[0008] Preferably, a sliding structure is formed between the inside of the lifting plate and the bolt hole, and the shapes of the top views of the lifting plate and the bolt hole are cross-shaped.

[0009] Preferably, a clamping structure is formed between the rubber block and the inner wall of the clamping groove, and the shape of the rubber block is an inverted frustum of a cone.

[0010] Preferably, a sliding structure is formed between the surface of the slider and the sliding rod, and the shape of the sliding rod is cross-shaped.

[0011] Preferably, anti-slip lines are equally angledly opened on the surface of the nut of the fixing bolt, and the shape of the anti-slip lines is arc-shaped.

The thread engagement between one end of the fixing bolt and the bolt hole is used to limit and fix the V-shaped plate after sliding. The sliding of the slider and the sliding rod surface allows the two support plates to slide back and forth. The engagement of the rubber block and the locking groove is used to limit and fix the support plates after sliding. In this way, the height and distance between the V-shaped plate and the support plate can be changed to accommodate crankshafts of different lengths and diameters, thus improving its applicability.

[0018] 2. By setting the adjustment component, the limit of the sliding plate after sliding is fixed, thereby changing the overall height of the adjustment component and the sliding plate, and making its height greater than the diameter of the crankshaft. Then, by using the forklift slot and the forklift forks to cooperate, the pallet can be lifted, and the bottom end of the sliding plate can be engaged with the inside of the slot, so as to realize the stacking of multiple pallets. At the same time, the height of the adjustment component and the sliding plate is adjustable to meet the stacking of crankshafts of different sizes, thus improving its practicality.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Example 1

[0028] A preferred embodiment of the crankshaft transport bracket provided by this utility model is as follows: Figures 1 to 5As shown: A crankshaft transport bracket includes a support plate 3; a fixed cylinder 4 fixedly connected to the four corners at the bottom of the support plate 3, with a sliding plate 8 slidably connected inside the fixed cylinder 4 extending to the outside of the fixed cylinder 4; an adjustment assembly 7 mounted on the fixed cylinder 4, the adjustment assembly 7 being used to limit and fix the sliding plate 8 after sliding; fixed grooves 11 equally spaced at the top of the support plate 3, a clamping groove 10 formed at the top of the support plate 3 on one side of the fixed groove 11, a sliding rod 12 fixedly connected to the inner wall of the fixed groove 11, a slider 19 movably connected to the surface of the sliding rod 12, a support plate 2 fixedly connected to the top of the slider 19, and a lower... A fixed plate 16 is fixedly connected to the end of the support plate 2. A threaded rod 17 is threadedly connected to the top of the fixed plate 16 and passes through the fixed plate 16. A rubber block 18 is rotatably connected to the bottom of the threaded rod 17. A reserved groove 22 is opened at the top of the support plate 2. A bolt hole 15 is opened at the upper end of the inner wall of the reserved groove 22. A lifting plate 13 extending to the outside of the support plate 2 is movably connected inside the reserved groove 22. Through holes 14 are opened at equal intervals on the lifting plate 13. A V-shaped plate 1 is fixedly connected to the top of the lifting plate 13. A fixing bolt 21 that passes through the through hole 14 and is threadedly engaged with the bolt hole 15 is movably connected to the upper end of one side of the support plate 2.

[0029] It should be noted that some existing crankshaft transport brackets still have certain shortcomings in actual use. Their comparative documents are not convenient for the secure placement of crankshafts of different lengths and diameters. Different specifications of crankshafts have different lengths and diameters, and V-shaped plates with fixed spacing and fixed height are difficult to be used for the placement of different crankshafts, which is not conducive to the handling of different crankshafts, resulting in low applicability.

[0030] In this embodiment, first adjust the sliding height of the V-shaped plate 1 according to the diameter of the crankshaft. At this time, loosen the fixing bolt 21 and remove it. Then, pull up the V-shaped plate 1 to drive the lifting plate 13 to slide up and down inside the reserved groove 22 to a suitable height. Then, pass the fixing bolt 21 through the appropriate through hole 14 and tighten it with the bolt hole 15 to achieve the limit fixation after the up and down sliding of the V-shaped plate 1, avoiding the situation that the large diameter of the crankshaft causes it to contact the top of the support plate 3 and the V-shaped plate 1 cannot support the crankshaft. At the same time, adjust the sliding distance of the two support plates 2 according to the length of the crankshaft. At this time, rotate the fixing plate 16 to drive the rubber block 18 to rise until it completely disengages from the inside of the clamping groove IO. Then, push the support plate 2 to make the slider 19 slide inside the sliding rod 12 to a suitable distance. Then, rotate the fixing plate 16 in the reverse direction to make the rubber block 18 snap into the inside of the rubber block 18 to achieve the limit fixation after the sliding of the support plate 2, so as to change the distance between the two support plates 2 to meet the placement of crankshafts of different lengths. At the same time, through the adjustment of different heights or lengths of multiple groups of V-shaped plates 1 and support plates 2, different crankshafts can be placed at one time, improving its applicability. Then, place the crankshaft on the V-shaped plate 1, and at the same time, the forklift slot 5 facilitates the insertion of the forklift fork, thus facilitating the handling of the support plate 3 by the forklift. When multiple support plates 3 need to be stacked and stored, the adjustment component 7 can be used to realize the sliding distance of the sliding plate 8 and limit fixation, so that the distance between multiple stacked support plates 3 is greater than the height of the crankshaft. Then, use the forklift to make the bottom end of the sliding plate 8 snap into the inside of the card slot 6 to achieve the stacked placement of multiple support plates 3.

[0031] In a further preferred embodiment of the present invention, an anti-slip rubber pad 9 is fixedly connected to the inner wall of the V-shaped plate 1, and the shape of the anti-slip rubber pad 9 is V-shaped.

[0032] In this embodiment, the V-shaped anti-slip rubber pad 9 is used to facilitate the placement and limit of the crankshaft.

[0033] In a further preferred embodiment of the present invention, a sliding structure is formed between the inside of the lifting plate 13 and the bolt hole 15, and the shapes of the top views of the lifting plate 13 and the bolt hole 15 are in the shape of a "rich" character.

[0034] In this embodiment, the sliding of the "rich" character-shaped lifting plate 13 inside the bolt hole 15 is used to improve the smoothness of the up and down sliding of the V-shaped plate 1.

[0035] In a further preferred embodiment of the present invention, a clamping structure is formed between the rubber block 18 and the inner wall of the clamping groove 10, and the shape of the rubber block 18 is a frustum of a cone.

[0036] In this embodiment, the clamping of the frustum of a cone-shaped rubber block 18 inside the clamping groove 10 is used to achieve the limit fixation after the sliding of the support plate 2.

[0037] In a further preferred embodiment of the present invention, a sliding structure is formed between the surfaces of the slider 19 and the sliding rod 12, and the sliding rod 12 is cross-shaped.

[0038] In this embodiment, the smoothness of the back-and-forth sliding of the support plate 2 is improved by utilizing the sliding between the cross-shaped sliding rod 12 and the slider 19.

[0039] In a further preferred embodiment of the present invention, the surface of the fixing bolt 21 nut is provided with anti-slip textures 20 at equal angles, and the shape of the anti-slip textures 20 is arc-shaped.

[0040] In this embodiment, the arc-shaped anti-slip texture 20 is used to improve the anti-slip friction of the user's fingers rotating the nut of the fixing bolt 21.

[0041] Example 2

[0042] Based on Embodiment 1, a preferred embodiment of the crankshaft transport bracket provided by this utility model is as follows: Figures 1 to 5 As shown: The adjustment assembly 7 includes: an adjustment groove 701 opened on one side of the bottom end of the fixed cylinder 4, a slide rod 703 extending to the outside of the fixed cylinder 4 slidably connected inside the adjustment groove 701, and a positioning block 704 fixedly connected to one end of the slide rod 703; a fixing spring 702 wound around the surface of the slide rod 703, with both ends of the fixing spring 702 fixedly connected to the inner wall of the adjustment groove 701 and one end of the slide rod 703 respectively; and positioning grooves 705 opened at equal intervals on one side of the sliding plate 8.

[0043] In this embodiment, by pulling the positioning block 704, the sliding rod 703 slides inside the adjusting groove 701, compressing the fixing spring 702 until it is completely disengaged from the positioning groove 705. Then, the sliding plate 8 is pulled to slide to a suitable distance, and the positioning block 704 is released. Using the elastic force of the fixing spring 702, the sliding rod 703 slides, causing the positioning block 704 to slide and lock into the appropriate positioning groove 705, thereby achieving the limiting and fixing of the fixed cylinder 4 and the sliding plate 8 after sliding.

[0044] In a further preferred embodiment of the present invention, one end of the positioning block 704 penetrates through the side wall of the fixing cylinder 4 and forms an engaging structure with the interior of the positioning groove 705. The positioning block 704 is L-shaped.

[0045] In a further preferred embodiment of this utility model, slots 6 are provided at the four corners of the top of the tray 3, and the bottom of the sliding plate 8 and the inside of the slots 6 form an engaging structure.

[0046] In this embodiment, the sliding plate 8 engages with the slot 6 to achieve stacking of the pallets 3.

[0047] In a further preferred embodiment of the present invention, forklift slots 5 are provided on both sides of the bottom end of the pallet 3, and the forklift slots 5 are rectangular in shape.

[0048] In this embodiment, the forklift slot 5 is used to facilitate the insertion of forklift forks, thereby facilitating the overall handling of the pallet 3 by forklift.

[0049] In summary, the adjustment component 7 is used to limit and fix the sliding plate 8 after it slides, and the engagement between the sliding plate 8 and the slot 6 is used to stack multiple trays 3. At the same time, the support plate 2 that can slide back and forth and the V-shaped plate 1 that can slide up and down are used to place crankshafts of different lengths and diameters, thus improving its applicability.
