[0002] The main bearing cap is a part installed on the thrust main bearing seat at the bottom of the cylinder block, and together with the cylinder block, fixes the crankshaft main journal. When assembling the thrust main bearing cap, the thrust main bearing cap must be precisely positioned in the axial direction to prevent axial misalignment during assembly of the thrust main bearing cap of the internal combustion engine. Otherwise, the thrust plate will be prone to abnormal wear, misalignment, loosening, jamming, falling off and other faults, and the crankshaft will be prone to movement, abnormal noise and other faults. In severe cases, it may even affect the normal operation of the crankshaft connecting rod component, thereby causing engine safety accidents.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a main bearing cover installation and transportation device of the present invention includes a cross-telescopic part 1, an expansion part 2, a lifting part 3, a telescopic part 4 and an installation and transportation part 5, the cross-telescopic part 1 is connected to the expansion part 2, and the expansion part 2 is connected to the lifting part 3, the telescopic part 4 includes a fixed part and a movable part, the fixed part of the telescopic part 4 is fixed on the lifting part 3, and the movable part of the telescopic part 4 is connected to the two grab bars 12 through the grab bar fixing hole 13, the cross-telescopic part 1 is used to grab the installation and transportation part 5, the expansion part 2 and the telescopic part 4 are used together for opening and closing the cross-telescopic part 1, and the lifting part 3 is used to connect with the crane.

[0020] like Figure 3 As shown, the installation and transportation part 5 of the present invention includes a movable clamping part 51, a support bottom 52, a sliding rod 53, a frame 54, a fixed support 55, a movable slide rod 56, and a spring 57. The frame 54 and the fixed support 55 are fixedly connected. The sliding rod 53 is connected between the frame 54 through the guide holes on both sides. The movable slide rod 56 is fixed to the upper part of the sliding rod 53, and the movable clamping part 51 is fixed to the lower part of the sliding rod 53. The support bottom 52 is set at the bottom of the frame 54. The fixed movable slide rod 56 passes through the fixed support 55 and is supported upward by the spring 57. Figure 3 As shown, when not being grabbed, the movable slide bar 56 of the transport portion 5 is driven upward by the spring 57, driving the movable clamping portion 51 and the slide bar 53 upward. Figure 1 As shown, after being grabbed, the moving part of the telescopic part 4 compresses the spring 57, causing the fixed moving slide 56 to move downward, thereby pressing the main bearing cover placed between the mobile clamping part 51 and the supporting bottom 52. The shapes of the mobile clamping part 51 and the supporting bottom 52 of the present invention can be set to different shapes according to the different models of the main bearing cover to be transported, such as providing a corresponding positioning guide module on the supporting bottom 52 to ensure stability during the moving process. The present invention reasonably optimizes the length of the mobile slide 56 so that after the main bearing cover is clamped by the mobile clamping part 51 and the supporting bottom 52, its force remains constant, and the main bearing cover will not be deformed due to manual over-tightening, or easily fall off due to being too loose, thereby improving the quality of the final product. At the same time, when the product is transported to the workstation, the mobile clamping part 51 automatically pops up, and the main bearing cover can be directly processed. In this way, the sub-station can be processed, and after the processing is completed, it can be quickly transported away by installing the transport part 5, thereby improving the processing efficiency of the product.

[0021] like Figure 4As shown, the cross telescopic section 1 of the present invention includes two identical grab bars 12. Each grab bar 12 has a hook 11 at its head and a grab bar fixing hole 13 at its mid-rear portion. These holes securely connect the two grab bars 12 to the movable portion of the telescopic section 4, forming a cross-shaped component that can move crosswise. Extension or retraction of the movable portion of the telescopic section 4 respectively contracts or expands the angles of the two grab bars 12. The rear ends of the two grab bars 12 are provided with holes for connection and fixing to the expansion section 2.

[0022] like Figure 5 As shown, the expansion section 2 of the present invention comprises two identical expansion rods 21, connected together by expansion fixing holes 22. These holes are also connected to the lifting section 3. The front end of each expansion rod 21 is provided with a hole that connects to the rear ends of two grab bars 12. When the movable portion of the telescopic section 4 is extended, the grab bars 12 gradually reduce the included angle of the expansion rods 21, allowing the installation and transport section 5 to be grasped. When the movable portion of the telescopic section 4 is retracted, the grab bars 12 gradually increase the included angle of the expansion rods 21, allowing the grab bars 12 to detach from the installation and transport section 5.

[0023] like Figure 6 As shown, the lifting portion 3 of the present invention includes a lifting rod 31 and a hook 32. One end of the lifting rod 31 is connected to the expansion fixing hole 22, and the other end is connected to the hook 32. The lifting rod 31 is fixedly connected to the fixed part of the telescopic portion 4. The telescopic portion 4 of the present invention can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0024] The working process of the present invention is as follows: first, the moving part of the telescopic part 4 is retracted, driving the grab bar 12 to gradually open. When the distance between the two grab bars 12 is greater than the distance between the fixed supports 55, the lifting part 3 moves down to the lower side of the fixed support 55, and then the moving part of the telescopic part 4 is extended, driving the grab bar 12 to gradually close and grab the lower part of the fixed support 55. Figure 1 As shown, the movable portion of the telescopic portion 4 is pressed downward, causing the movable slide 56 to move downward. When the gripping rod 12 of the device of the present invention is tightened, it limits the extension length of the movable portion of the telescopic portion 4, that is, limits the downward position of the movable slide 56. From a structural perspective, it ensures that the device does not press too tightly and does not affect the main bearing cap structure, thereby improving product quality.
