Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and specifically relates to an auxiliary tool for hanging an engine. Background Art

[0002] In the automotive industry, engines are usually produced in the engine factory and then transported to the main vehicle manufacturer. They are then assembled with other accessories on the main vehicle manufacturer's powertrain assembly line before being assembled on the vehicle body. The engine is hoisted during the production and transportation process, so a pair of lifting ears are usually designed when designing the engine to facilitate engine hoisting.

[0003] The patent number is 202311477556.5, and the disclosure date is January 2, 2024. In a public specification, a diesel engine flywheel housing hoisting auxiliary equipment is disclosed, which relates to the field of hoisting equipment. It includes: a load-bearing frame, which is a load-bearing frame structure; a flap, one end of which is rotatably hinged and set on one side of the load-bearing frame, and the other end is flipped with its hinged end as the rotation center; a flip drive mechanism, which is set between the load-bearing frame and the flap to drive the flip of the flap; a support column, whose upper end is vertically connected to the lower surface of the flap and flips with the flap, and the lower end of the support column is used to pass through the bearing hole of the diesel engine flywheel housing; a clamping mechanism, which is set at the lower end of the support column to limit and clamp on one side of the flywheel housing bearing hole; a clamping switch driving mechanism, which is set on the support column to control the switch of the limit clamping function of the clamping mechanism; a tightening mechanism, which is set on the support column to tighten on the flywheel housing opposite to the limit side of the clamping mechanism; and an auxiliary positioning mechanism.

[0004] However, the engine lifting ear design also increases the cost in disguise. Each engine needs to be designed with at least two lifting ears, and the layout of the lifting ears also needs to be considered when designing the lifting ears. Not only do they need to avoid other engine accessories, but the designed lifting ears must be easy to operate when used in conjunction with the lifting hooks, and other accessories must not be damaged during the lifting process. On the powertrain assembly line of the automobile main engine factory, the lifting ears are usually disassembled and scrapped during the engine assembly process, which also results in cost waste. In addition, a separate disassembly tool is required, which results in cost waste. Utility Model Content

[0020] The following will, with reference to the accompanying drawings, further elaborate on the specific implementation manners of the present utility model through the description of embodiments, aiming to help those skilled in the art have a more complete, accurate, and in-depth understanding of the inventive concept and technical solutions of the present utility model and facilitate its implementation.

[0021] Please refer to Figure 1-2 , an auxiliary tool for hoisting an engine, which includes a connecting block 1 arranged on the side of the engine. A lifting lug 2 is installed on the connecting block 1 through a stud. The connecting block 1 is provided with a fixing structure for clamping the connecting block 1 to the engine. First, the fixing structure of the connecting block 1 is matched with the engine block. After the matching is in place, the hook of the hoisting tool can be directly hung into the hoisting hole of the lifting block for hoisting. After the hoisting is completed, structures such as the lifting lug 2 and the connecting block 1 can be disassembled from the engine, which is convenient for repeated use. At the same time, there is no need to equip disassembly tools, reducing the tool development cost.

[0022] The fixing structure includes an upper clamping block 3 and a lower clamping block 4 arranged on the connecting block 1. The upper clamping block 3 and the lower clamping block 4 are attached to the surface of the engine. The fixing structure also includes a limiting block 5 sleeved on the engine stud. A baffle 6 is provided on the limiting block 5 on the side of the connecting block 1 away from the engine. The upper and lower clamping blocks 4 of the connecting block 1 are clamped at the upper and lower ends of the cylinder block module. After the engine is hoisted, the Z-direction force of the connecting block 1 will be transferred to the engine block, but the X-direction and Y-direction degrees of freedom are not restricted. At this time, after the limiting block 5 is installed on the double-headed stud, the X-direction and Y-direction of the limiting block 5 itself are restricted and cannot move. Then, the baffle of the limiting block 5 is embedded in the limiting groove of the connecting block 1, which can limit the X-direction and Y-direction movement of the connecting block 1. In this way, the X-direction, Y-direction, and Z-direction of the connecting block 1 are all restricted, and it can be regarded as integrated with the engine assembly, meeting the requirements of hoisting and lowering.

[0023] The limiting block 5 is in a T shape, and the limiting block 5 is provided with an insertion hole 7 that matches the engine stud. By inserting the stud of the engine into the insertion hole 7, the effect of fixing the limiting block 5 is achieved, and thus the main connecting block 1 is restricted by the baffle 6 at the bottom of the limiting block 5.

[0024] A nylon sheath 8 sleeved on the outside of the stud is provided in the insertion hole 7. The stud is protected by the nylon sheath 8 to prevent the stud from being damaged by extrusion.

[0025] The connecting block 1 is provided with a limiting groove 9 that matches the baffle 6, and the limiting groove 9 penetrates the surface of the connecting block 1. The baffle 6 is restricted by the limiting groove 9, thereby fixing the connecting block 1 in the reverse direction and preventing the connecting block 1 from sliding left and right, causing the connecting block 1 to fall off from the side of the engine.

[0026] The lifting lug 2 is divided into a lifting ring 21, a fixing plate 22 and a vertical plate 23 arranged between the lifting ring 21 and the fixing plate 22. The fixing plate 22 is fixed on the connecting block 1 by screws. While the screws are convenient for installation and disassembly, they are also fixed more firmly. At the same time, due to the existence of the vertical plate 23, the lifting ring 21 can be kept away from the connecting block 1 to avoid collision during hoisting.

[0027] The width of the fixing plate 22 is greater than the width of the vertical plate 23, and four screw holes are evenly arranged on the fixing plate 22. The larger-area fixing plate 22 can make the fixing of the lifting lug 2 more firm and reduce the occurrence of loosening.

[0028] The upper clamping block 3 and the lower clamping block 4 are arranged on the upper and lower sides of the connecting block 1 to limit the connecting block 1 from the upper and lower sides.

[0029] The limiting block 5 is provided with a waist-shaped hole 10 to reduce the overall weight and cost.

[0030] The technical effect of the present utility model is as follows: First, the upper and lower clamping blocks 4 of the connecting block 1 are matched with the engine cylinder block, and then the limiting block 5 is installed in place. The blocking block of the limiting block 5 is located in the groove of the connecting block 1. After being matched in place, the hook of the lifting tool is hung into the lifting hole of the lifting block to directly lift. After the hoisting is completed, the structures such as the lifting lug 2 and the connecting block 1 can be disassembled from the engine, which is convenient for repeated use. At the same time, there is no need to equip disassembly tools, reducing the tool development cost.

[0031] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
