Hereinafter, the configuration and operation of the clearance adjusting device for heavy equipment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view illustrating an installation example in which the heavy-duty clearance adjustment device according to an embodiment of the present invention is mounted, and FIG. 2 is a cross-sectional view taken along line II-II when the heavy-duty clearance adjustment device of FIG. 1 is mounted. to be.

The clearance adjustment device for heavy equipment according to the embodiment shown in FIG. 1 is coupled to the outer side of a hinge pin 6 rotatably connecting the first member 5 and the second member 7 of the heavy equipment to the first member 5. And a gap generated between the second member 7.

Heavy equipment such as excavators, wheel loaders, tractors, forklifts, etc. are equipped with work tools connected to hydraulic cylinders operated by the driving force of the hydraulic system. For example, excavators are connected with work tools such as booms, arms and buckets by linkage connection assemblies. The link connection assembly is an assembly that connects each of the working machines to be relatively rotatable using a hinge pin.

The first member 5 and the second member 7 are shown as an example of such a link connecting assembly, and the assembly in which the heavy-duty play adjustment device of the present invention can be used is limited to the connecting assembly of the configuration shown in FIG. It doesn't happen.

The first member 5 and the second member 7 are rotatably coupled to each other by a hinge pin 6 penetrating the first member 5 and the second member 7. The hinge pin 6 may maintain a state in which the hinge pin 6 is coupled to the first member 5 and the second member 7 by the fixing member 8 attached to the outside of the first member 5.

If heavy equipment having such a configuration of a connection assembly is operated for a long time or repeatedly processes heavy workloads, play g may occur between the first member 5 and the second member 7. As the size of the clearance g generated between the first member 5 and the second member 7 increases, the relative movement of the first member 5 and the second member 7 becomes unstable and the first member ( The structures connecting 5) and the second member 7 may be broken.

In addition, grease is injected into the connecting portions of the second member 7 and the hinge pin 6 of the first member 5 so that the relative rotational movement of the first member 5 and the second member 7 is smoothly performed. As the degree of play (g) increases, the amount of grease injected can also increase significantly.

Thus, the clearance g generated between the first member 5 and the second member 7 causes many problems that are undesirable for heavy equipment, so the clearance g is preferably adjusted quickly. However, in the related art, the process of disassembling and reassembling the rigid assembly structure of the first member 5, the second member 7, and the hinge pin 6 and adjusting the clearance g is very cumbersome and time-consuming. There was a problem.

However, using the heavy-duty clearance adjustment device shown in FIG. 1, the first member 5 and the second member 7 may be separated without the work of disassembling the first member 5 and the second member 7. The clearance g generated in between can be easily adjusted. That is, as shown in FIG. 1, the gap g is a simple operation of inserting the clearance adjustment device 10 for heavy equipment through the gap g existing between the first member 5 and the second member 7. This is adjusted.

Preferably, the clearance adjustment device for heavy machinery having a thickness t substantially equal to the size of the clearance g is measured by measuring the clearance g generated between the first member 5 and the second member 7. (10) can be selected. Therefore, when the clearance adjusting device 10 for heavy equipment is inserted through the clearance g, it may be installed in a fitting manner.

The clearance adjustment device 10 for heavy equipment has the tool contact part 40 which protrudes toward the outer side from the outer peripheral surface. Therefore, when inserting into the clearance g by the force fitting method, the tool contact part 40 is hit by using a tool such as a hammer to easily insert the heavy-duty clearance adjustment device 10 into the clearance g. can do.

The clearance adjustment device for heavy equipment 10 inserted through the clearance g is inserted between the first member 5 and the second member 7 and coupled to the hinge pin 6 as shown in FIG. 2. The state can be kept stable. Therefore, the phenomenon that the relative rotational movement is unstable due to the clearance g existing between the first member 5 and the second member 7 can be eliminated.

3 is a plan view of the clearance adjustment device for heavy equipment of Figure 1, Figure 4 is a perspective view of the clearance adjustment device for heavy equipment of FIG.

The clearance adjustment device 10 for heavy equipment is provided with the main body part 20 which consists of a ring-shaped plate material, and the insertion guide part 30 formed by opening one side of the main body part 20. As shown in FIG. Since the main body 20 is made of a ring-shaped plate, it has an inner circumferential surface 21 and an outer circumferential surface 22. The inner circumferential surface 21 has a size corresponding to the outer circumferential surface of the hinge pin 6 connecting the first member 5 and the second member 7. When the main body 20 is coupled to the hinge pin 6, the inner circumferential surface 21 supports the outer circumferential surface of the hinge pin 6, so that the first member 5 and the second member 7 are hinge pins 6. ) Can be rotated relatively (see FIG. 2).

The main body portion 20 is formed with an insertion guide portion 30 that opens in the radial direction from the inner circumferential surface 21 to the outer circumferential surface 22. The insertion guide portion 30 is provided with a hinge pin 6 passing through the hinge pin 6 when the clearance adjustment device for heavy equipment 10 is inserted into the clearance g between the first member 5 and the second member 7. This is a part for guiding the movement of the hinge pin 6 to be inserted into the main surface (21).

The body portion 20 may have a tool contact portion 40 projecting outwardly in the radial direction from the outer circumferential surface 22. The tool contact part 40 is a part for transmitting a hitting force when hitting the main body part 20 using a tool, such as a hammer, when inserting the clearance adjustment device 10 for heavy equipment in the clearance g.

In addition, the tool contact portion 40 has a tool engaging groove 41 into which a tool such as a driver can be inserted.

It is not easy to rotate the clearance adjusting device 10 for heavy machinery among (). The tool coupling groove 41 may be used to rotate the main body 20 inserted into the play g or to remove the main body 20 from the play g again.

The width H of the insertion guide 30 may be slightly smaller than the diameter D of the hinge pin 6. Therefore, when the hinge pin 6 comes into contact with the inlet of the insertion guide 30, when the impact force of a tool such as a hammer is applied to the clearance adjusting device 10 for heavy equipment through the tool contact 40, the insertion guide 30 is applied. The inner circumferential surface 21 may be coupled to the hinge pin 6 while being slightly opened to the outside.

When the impact force of the tool is applied, the insertion guide 30 should be able to cause a slight deformation, so the clearance adjusting device 10 for heavy equipment is slightly deformed by an external impact such as steel or aluminum. It can be made of metal material with elasticity enough to cause. However, the clearance adjustment device 10 for heavy equipment is not limited to a metallic material and may be made of other materials, such as engineering plastics, which may cause some deformation by an impact applied.

The insertion guide portion 30 has an inclined portion 32 that forms an inclined gap from the inner side of the insertion guide portion 30 toward the outside at the end of the insertion guide portion 30 in contact with the outer circumferential surface 22 of the main body portion 20. ) May be formed. The cutting portion 32 is inserted guided when the impact force of the tool is applied to the clearance adjusting device for heavy equipment 10 through the tool contact portion 40 when the hinge pin 6 contacts the inlet of the outer insertion guide portion 30. The unit 30 serves to easily enter the outer circumferential surface of the hinge pin (6).

Insertion guide portion 30 is in the circumferential direction at the portion in contact with the inner circumferential surface 21 of the insertion guide portion 30 to support the hinge pin 6 inserted into the inner circumferential surface 21 of the main body portion 20. Accordingly, a hinge pin support part 31 extending in the inward direction of the insertion guide part 30 may be further provided.

The body portion 20 is formed with a grease hole 50 extending therethrough in a direction parallel to the hinge pin 6. The grease hole 50 serves as a passage through which air flows so that the main body 20 can be smoothly inserted into the clearance g, and after the clearance adjustment device 10 for heavy equipment is mounted. When grease is injected, the grease can function as a passage for the grease to be smoothly distributed between the first member 5, the second member 7, and the main body 20.

When the clearance adjustment device for heavy equipment 10 having the above-described configuration is used, the main body portion having a thickness t corresponding to the clearance g generated between the first member 5 and the second member 7 ( Since the state 20 is stably maintained between the first member 5 and the second member 7, the clearance g can be adjusted reliably. In addition, since the clearance adjusting device 10 for heavy equipment can be installed by a simple operation of contacting the hinge pin 6 to the insertion guide 30 and hitting it, the first member 5 and the second member 7 and the hinge There is an advantage that it is not necessary to perform the cumbersome work of disassembling the components such as the pin (6).
