Description

Industrial equipment grease pin

The present invention relates to a grease pin for industrial equipment, a feature of the present invention is to improve the structure of the grease pin connecting the bent portion of various industrial equipment, etc. to inject grease into the grease pin to bend easily It is.

In general, various types of industrial equipment such as payloader, crane, bulldozer, dump, etc. are equipped with arms or booms that can be bent in multiple stages. These various equipments are mainly used for yard work, dumping or excavation, etc., and the grease pin is coupled to the connecting means of each bracket to achieve this function, so that the grease pin acts as a hinge. It achieves the purpose of bending or angular movement.

Meanwhile, the grease pin for operating the arm or the boom is formed as a hollow body as a means for smoothing the operation, thereby smoothing the operation by injecting grease through a conduit formed in the grease pin.

However, in the case of the grease pin connecting the existing bent portion has a number of problems as described below, there is an urgent need for means to solve this problem.

In other words, the bent parts of the existing industrial equipment, respectively, the bracket can be mutually coupled to each other, the grease pin coupled as a means for connecting these brackets by selecting a strong material on its own to prevent wear Mostly made of special steel to prevent breakage and the like.

In addition to these functions, the grease pins coupled to the respective brackets are fixed, but the brackets must be angularly moved at an appropriate angle according to the purpose or function. In order to facilitate such angular movements, grease is formed at the center of the grease pins. The pipe is formed by connecting a grease injection gun through the injection nozzle by joining injection nozzles by forming a screw hole at the edge corresponding to the inlet side of the pipeline and coupling injection nozzles. The grease supplied through the discharge is discharged to the discharge part side and is evenly applied to the inner wall surface of each bracket, so that the grease serves as lubricating oil so that each bent part operates smoothly.

However, in the case of the grease pins used so far, the discharge portion formed at the end of the pipe is formed in the same size as the pipe, not the step type, so that the grease is solidified in the gal state due to long-term oiling during the use of the equipment. Of course, the discharge port is clogged due to the input of dust or foreign substances generated during the use of the equipment.

In particular, when foreign substances such as dust such as payloader, crane, bulldozer, dump, etc. are directly inputted, the grease solidifies relatively quickly and the grease dries quickly due to the high temperature generated from the grease pin of the bent portion. As a result, the discharging port of the front end of the pipe is blocked, and thus, the injection of grease cannot be performed smoothly.

In addition, since the discharge portion of the grease is blocked as described above, the operation of the bracket is not desired, and thus the grease pin is separated, and then the pipe and the discharge portion connected thereto are opened.

In this case, since the grease is dried on the surface of the grease pin, it is very difficult to separate the grease pin from the bracket. Thus, the grease pin is separated by a separate hitting means while the bracket is heated at a high temperature.

In this process, high heat is transmitted to the grease pin, which causes deformation or rapid weakening of the durability, which can cause fatal accidents when reuse, and grease can not be supplied smoothly. Severe noise is generated in the process, and in some cases, there was an excessive problem of disassembly and replacement of equipment and loss of time.

Therefore, the present invention has been made to solve the problems of the conventional grease pins as described above, the present invention is partly to improve the structure of the grease pins of various uses that are being used in the past, as well as ease of use, It basically prevented the confinement of the grease pin pipe and discharge port so that it can be used reasonably as grease pin for various industrial equipment.

The present invention provides a separate expansion part larger than the size of the conduit at the end of the discharge section installed in the same size as the pipe that is penetrated into the existing grease pin, so that the grease supply is made smoothly, as well as dust or foreign matter during the operation. Even if it is injected, it prevents the phenomenon of drying easily, and in particular, since the enlarged portion is formed larger than the specification of the discharge portion, the discharge portion is prevented from clogging, and the enlarged portion formed in the discharge portion is configured in multiple stages to meet the function. In some cases, the slope, horizontal, arc, and vertical planes can be modified appropriately so that the size of the extension can be arbitrarily changed, thereby widening the selection and supplying grease smoothly according to the specifications of each extension. To prevent overload or malfunction of equipment As well as providing a straight rod, a curved rod and a lattice rod in which grease can move from the discharge part as a starting point, grease can be supplied smoothly through each rod and can be easily operated. By combining a separate check valve to prevent backflow, it is possible to prevent the backflow of grease discharged through the discharge part to the pipe side, which makes it possible to obtain a very reasonable effect as a grease pin for various industrial equipment. Hereinafter, the structural features for achieving the above object of the present invention will be described in detail with the accompanying drawings.

It is characterized in that it is possible to fundamentally prevent the phenomenon that the conduit 11 and the discharge portion 13 of the c), the use and function of the present invention will be described.

The present invention separates the expansion portion 20 having a larger size than the size of the conduit 11 at the distal end of the discharge portion 13 installed in the same size as the conduit 11 penetrated inside the existing grease pin 10 separately. By providing a smooth supply of grease as well as preventing the phenomenon that the discharge part 13 is easily dried even when dust or foreign matter is introduced during the operation, the enlarged part 20 is a standard of the discharge part 13. Since it is formed larger, the discharge part 13 is prevented from being clogged, and the expansion part 20 formed in the discharge part 13 is configured in multiple stages to perform a function that meets the conditions. By appropriately modifying the inclined surface 22, the horizontal surface 23, the arc surface 24, and the vertical surface 21, the size of the extension portion 20 can be arbitrarily changed, thereby widening the choice and widening the angle.
