[0008] Preferably, a second support column is fixedly connected to the outer side of the bottom of the Y-shaped bracket, and a second movable plate is rotatably connected to the second support column. The movement of the Y-shaped bracket can be easily changed by moving the second movable plate and the second support column.

[0009] Preferably, the fixing block has a groove inside, and the support plate can slide inside the groove.

[0010] Preferably, a first rubber pad is fixedly connected to the inner side of the Y-shaped bracket, and a second rubber pad is fixedly connected to the top of the support plate, which prevents the crankshaft from sliding and protects the surface of the crankshaft.

[0011] Preferably, the base is fixedly connected to the bottom of the support base, and bolts are threaded to the four corners of the base through threaded holes. Holes are drilled in the ground or the required support surface, and the threaded holes are aligned with the drilled holes and bolts are used to fix the base.

[0012] Compared with related technologies, the universal medium-speed diesel engine crankshaft support tool provided by this utility model has the following beneficial effects:

[0013] This utility model provides a universal medium-speed diesel engine crankshaft support tool.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 4This utility model provides a universal medium-speed diesel engine crankshaft support tool, comprising: a Y-shaped bracket 1, a fixing block 6 hinged to the inner bottom of the Y-shaped bracket 1, a return spring 10 fixedly connected to the middle inside the fixing block 6, a support plate 7 fixedly connected to the top of the return spring 10, a support seat 2 fixedly connected to the middle bottom of the fixing block 6, fixing plates 12 fixedly connected to both sides below the support plate 7, a plurality of racks 13 fixedly connected to the outer surface of the fixing plate 12, the racks 13 meshing with gears 11, a first support column 14 fixedly connected to the lower inner front part of the gears 11, and a first moving plate 15 rotatably connected to the first support column 14. The other end of the first movable plate 15 is fixedly connected to the second movable plate 16. The gear 11 is rotatably connected inside the fixed block 6. The bottom outer side of the Y-shaped bracket 1 is fixedly connected to the second support column 17. The second movable plate 16 is rotatably connected to the second support column 17. The crankshaft is placed on the support plate 7 according to the size of the crankshaft, so that the support plate 7 moves downward under the weight of the crankshaft, which drives the fixed plate 12 and the rack 13 to move downward, which drives the gear 11 to rotate. The gear 11 can only rotate at most half, which drives the first movable plate 15 and the second movable plate 16 to move away from the return spring 10, which lifts the bottom left side of the Y-shaped bracket 1, so that the Y-shaped bracket 1 moves closer to each other, which is convenient for clamping and fixing the crankshaft.

[0022] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The fixed block 6 has a hollow groove 9 inside, and the support plate 7 can slide inside the hollow groove 9.

[0023] In the embodiments of this utility model, please refer to Figure 1 The Y-shaped bracket 1 has a first rubber pad 4 fixedly connected to its inner side, and the support plate 7 has a second rubber pad 5 fixedly connected to its top, which prevents the crankshaft from sliding and protects the surface of the crankshaft.

[0024] In the embodiments of this utility model, please refer to Figure 4 The base 3 is fixedly connected to the bottom of the support 2. The four corners of the base 3 are threaded with bolts 8 through threaded holes 18. Drill holes in the ground or the required support surface, align the threaded holes 18 with the drilled holes and use bolts 8 to fix the base 3.

[0025] The working principle of the universal medium-speed diesel engine crankshaft support tool provided by this utility model is as follows: First, drill holes in the ground or the required support surface, align the threaded hole 18 with the drilled hole, and fix the base 3 with bolts 8. The Y-shaped bracket 1 is divided into crankshafts that can support 300mm-420mm journals and crankshafts with 180mm-290mm journals. According to the size of the crankshaft, place the crankshaft on the support plate 7, so that the support plate 7 moves downward under the weight of the crankshaft, driving the fixed plate 12 and the rack 13 to move downward, driving the gear 11 to rotate. The gear 11 can only rotate up to half, driving the first moving plate 15 and the second moving plate 16 to move away from the return spring 10, lifting the bottom left side of the Y-shaped bracket 1, so that the Y-shaped brackets 1 are close to each other, clamping and fixing the crankshaft. When not in use, the support plate 7 is reset by the return spring 10 for convenient subsequent use. Multiple support tools can be combined according to different lengths of crankshafts, which is convenient for cleaning, inspection, measurement and other work of the crankshaft outside the diesel engine.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
