Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, and in particular to a tool for removing diesel engine piston connecting rods. Background Technology

[0002] In the repair of main and auxiliary engines of ships, it is often necessary to remove, replace, clean, and maintain cylinder pistons and connecting rods. Without suitable disassembly tools, it is often difficult to remove the pistons and connecting rods smoothly. The process of removing the pistons and connecting rods is time-consuming because the pistons and connecting rods are heavy and the cylinder liners and pistons are precision friction surfaces. If the pistons and cylinder liners are damaged during the removal of the pistons and connecting rods, it will cause significant economic losses. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a diesel engine piston connecting rod disassembly tool, which solves the current pain point in this field.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A diesel engine piston connecting rod removal tool includes a base with two through holes. A rib plate is fixedly installed on the base and secured to the rib plate by two brackets. The upper part of the rib plate is a crossbar with five lifting holes. A crane hook is fixed to two of the lifting holes on the rib plate. Different combinations of two lifting holes are selected for different piston connecting rods.

[0006] To further explain, the upper part of the rib plate is an inclined crossbar.

[0007] To further explain, the hoisting holes are arranged in a straight line and have the same inclination as the crossbar of the rib plate. After the base is fixed to the piston connecting rod.

[0008] In summary, the advantages of this utility model compared to the prior art are as follows: This tooling is designed to be installed on the piston based on the size and structure of the piston connecting rod. The tooling is fixed by the lifting threaded hole on the piston to adjust the lifting force point and the force direction. During the disassembly of the piston connecting rod, it can ensure that there is no risk of damage to the piston connecting rod. The disassembly is quick, effective and saves time and effort. Attached Figure Description

[0009] The above and other objects, features, and advantages of the present invention will become readily apparent from the following detailed description of exemplary embodiments, taken in conjunction with the accompanying drawings. Several embodiments of the present invention are illustrated in the drawings by way of example and not limitation, in which:

[0011] Explanation of reference numerals in the attached diagram: 1. Base; 2. Through hole; 3. Rib; 4. Lifting hole. Detailed Implementation

[0012] The utility model will be further described in detail below with reference to the accompanying drawings.

[0013] A diesel engine piston connecting rod removal tool includes a base 1 with two through holes 2. Bolts are passed through the through holes 2 to fix the base 1 to the piston connecting rod. A rib plate 3 is fixedly installed on the base 1 and is fixed to the rib plate 3 by two brackets. The upper part of the rib plate 3 is an inclined crossbar with five lifting holes 4 arranged in a straight line and at the same inclination as the crossbar. After the base 1 is fixed to the piston connecting rod, a crane hook is fixed into two of the lifting holes 4 on the rib plate 3. For different piston connecting rods, different combinations of two lifting holes 4 can be selected to adjust the lifting force of the piston connecting rod to be in the same direction as the piston movement, so that the piston connecting rod is lifted vertically relative to the cylinder liner during the lifting process, avoiding contact and collision between the piston connecting rod and the cylinder liner, and ensuring that the piston connecting rod is lifted out stably and safely.

[0014] The above description is merely an exemplary embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The scope of protection of the present utility model is determined by the appended claims.
