Description

Technical Field

[0001] This utility model relates to the field of lifting tools technology, specifically a lifting tool assembly for lifting diesel engine air coolers. Background Technology

[0002] The diesel engine air cooler, also known as the diesel engine air cooler, is an important component of the diesel engine cooling system. It is mainly used to cool the air entering the diesel engine to improve the intake air density and efficiency, thereby improving the overall performance and reliability of the diesel engine. When installing air coolers for large diesel engines, due to the large size and weight of individual air cooling components, and the lack of lifting components such as lifting lugs or lifting holes on the air cooler body.

[0003] The existing method for hoisting this type of air cooler typically involves binding it with slings or wire ropes. However, this method has several drawbacks: 1. Slow hoisting speed, impacting work efficiency; 2. Improper binding and protection can easily contaminate the surface of the air cooler and damage the paint, affecting project acceptance; 3. The length of the slings or wire ropes is difficult to control, making it difficult to achieve the required angle for installation, which is detrimental to air cooler installation; 4. Insufficient binding of the air cooler with slings or wire ropes can easily lead to safety accidents. Therefore, a new type of lifting assembly is needed for air cooler hoisting operations.

[0004] Therefore, it is necessary to provide a new lifting tool assembly for diesel engine air cooler hoisting operations to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lifting tool assembly for lifting diesel engine air coolers.

[0006] The lifting tool assembly for diesel engine air cooler hoisting operations provided by this utility model includes:

[0007] The lifting equipment consists of two sets arranged symmetrically, and includes a base plate and a lifting plate.

[0008] The lifting platform consists of two trapezoidal base plates, with a lifting plate fixedly connected to the top of each base plate. Lifting holes are provided in the center of each lifting plate, and anti-wear sleeves are fitted inside the multiple lifting holes.

[0009] Preferably, each of the four corners of the two sets of base plates has mounting holes, and the interior of each of the multiple sets of mounting holes is movably connected with fixing bolts. The lifting device can be installed onto the diesel engine air cooler through the fixing bolts.

[0010] Preferably, one side of each of the two sets of lifting plates is fixedly connected with a stiffening plate, and the bottom end of the stiffening plate is fixedly connected to the base plate. The stiffening plate can strengthen the lifting device. The material of the two sets of base plates, lifting plates and stiffening plates is Q345B.

[0011] Preferably, springs are fixedly connected to the center of the bottom of both sets of base plates, and buffer plates are fixedly connected to the bottom of both sets of springs. The buffer plates can prevent the diesel engine air cooler from shaking during hoisting.

[0012] Preferably, a fixed seat is fixedly connected to one side of each of the two sets of base plates, a roller is installed on each of the two sets of fixed seats, and a strap is fitted on each of the two sets of rollers. The straps can be used to fix the position of the hoisted diesel engine air cooler to prevent it from shaking.

[0013] Preferably, the other end of each of the two sets of straps is fixedly connected to a connector, and the two sets of connectors are respectively fitted onto the fixed head. The other end of the strap can be fixed by the connectors.

[0016] Compared with related technologies, the lifting tool assembly for diesel engine air cooler hoisting operations provided by this utility model has the following beneficial effects:

[0017] This utility model provides a lifting tool assembly for lifting diesel engine air coolers;

[0018] 1. This utility model can perform lifting operations on diesel engine air coolers using a lifting plate. When lifting a diesel engine air cooler is required, the base plate can be placed at the corresponding installation position of the diesel engine air cooler. Fixing bolts can be threaded into the threaded holes of the diesel engine air cooler using tools. Lifting operations can be performed by passing lifting ropes through the lifting holes. Compared with the traditional lifting lug method, the combination of the base plate, lifting plate, and stiffening plate is more stable. The force is transferred to the base plate by the vertical connection between the base plate and the lifting plate. The base plate has multiple sets of mounting holes for connecting fixing bolts, allowing the multiple sets of fixing bolts on the base plate to also bear tensile force. In addition, the stiffening plate strengthens the load-bearing capacity of the lifting plate and the side of the base plate, thereby realizing the rapid installation of the lifting tool and the uniform force on the surface of the base plate and the air cooler, making the lifting operation safer.

[0019] 2. This utility model can be made of Q345B material for the lifting device, which has high tensile strength and yield strength. When lifting the air cooler using the lifting assembly of this utility model, there is friction between the top of the air cooler body and the bottom surface of the lifting device base plate, and there is also friction when the lifting rope passes through the lifting hole. The above-mentioned contact surfaces with friction are coated with wear-resistant paint to increase wear resistance and hardness, thereby extending the service life of the lifting device. In addition, all fixing bolts adopt standard part grade 8.8 GB / T5783-00_M24x70, and the maximum tensile force on the bolts is calculated to be 2.2t. Attached Figure Description

When using the lifting assembly of this utility model to lift the air cooler, there is friction between the top of the air cooler body and the bottom surface of the lifting device base plate 1, and there is friction when the lifting rope passes through the lifting hole 7. The aforementioned contact surfaces with friction are coated with wear-resistant paint to increase wear resistance and hardness, and extend the service life of the lifting device. In addition, the fully fixed bolts 6 adopt standard part grade 8.8 GB / T5783-00_M24x70, and the maximum tensile force on the bolts is calculated to be 2.2t.

[0038] The working principle of the lifting tool assembly for diesel engine air cooler hoisting operations provided by this utility model is as follows:

[0039] When using this system, firstly, when hoisting the diesel engine air cooler, the base plate 1 is placed at the corresponding installation position of the diesel engine air cooler. Then, using tools, the fixing bolts 6 are threaded into the threaded holes of the diesel engine air cooler. The hoisting operation is then performed by passing the lifting rope through the lifting holes 7. Compared to traditional hoisting methods using lifting lugs, the combination of the base plate 1, lifting plate 2, and stiffening plate 3 is more stable. The vertical connection between the base plate 1 and the lifting plate 2 transfers force to the base plate 1. The base plate 1 has multiple sets of mounting holes 4 for connecting the fixing bolts 6, allowing these bolts to also bear tensile force. The stiffening plate 3 further reinforces the system. The lifting plate 2 and the side of the base plate 1 bear the load, thereby enabling rapid installation of the lifting tool and ensuring uniform stress on the base plate 1 and the surface of the air cooler, making the lifting operation safer.
