JIG FOR EXTRACTING THE FASTENED PIN TO THE HAMMER OF IMPACT CRUSHER}

The present invention relates to a hammer fixing pin for drawing jig for impact crusher, and more specifically, hammer fixing pin for impact crusher for automatically drawing out the fixing pin of the hammer pin fixed to the rotary arm of the impact crusher, which is a coal crusher It is about an external jig.

In general, the impact crusher is used for the purpose of crushing the out-of-standard crushed among the primary crushed in the coal mining and aggregate production process, the impact crusher facility, as shown in FIG. Rotating arm (2) fastened to bush (1) of rotary rotor (1a) powered by drive belt (6) from hammer (7), and hammer (4) fastened with fixing pin (3) at its end is crusher cover (5) It is to crush the introduced crushed object by rotating inside.

As described above, when the shredding object introduced into the impact crusher is crushed for a long time, the hammer (4) coupled to the end of the rotary arm (2) is worn or burned and replaced, the conventional hammer replacement method is the impact The crusher is stopped and the ring stopper 14 which fixes the pin from the rotary arm 2 is removed, and then a worker manually hits the fixing pin 3 to penetrate the pin through hole 4a of the hammer 4. I have been using a method to remove from.

When removing the fixing pin (3) by the blow method by the manual work as described above, equipment troubles such as stenosis and breakage of various sensors, rupture of the hydraulic line and damage to the rotor bush (1) due to the detachment of the support round bar due to the blow In addition to the occurrence of frequent occurrences, there is a problem that the potential for increased fatigue and safety accidents of workers at all times.

In order to solve the above problems, the present invention automatically removes the hammer fixing pin safely and safely when replacing the hammer of the impact crusher, the hammer fixing pin of the impact crusher for fixing the equipment and protecting the worker from the workload and the risk of accident The purpose is to provide.

In order to achieve the above object, the present invention is a pin out of the plate formed in the center of the hole is fixed to the rotating arm of the impact crusher and the fixing pin hammer, and the hydraulic cylinder is fixed to remove the fixing pin The hammer fixing of the impact crusher, comprising a cylinder fixing plate having a through hole, a pin take-out liner bolted to the inner upper and lower surfaces thereof, and an upper and a lower plate bolting the pin take-out plate and the pin take-out liner. It will provide a pin takeout jig.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing a state in which the hammer fixing pin for taking jig for impact crusher coupled to the hammer fixing portion according to the present invention, Figure 3 is an exploded perspective view of the hammer fixing pin for taking jig for impact crusher according to the present invention to be.

As shown in Figures 2 to 3, the hammer fixing pin of the impact jig for ejecting jig of the impact crusher according to the present invention end of the rotary arm (2) is fixed to the rotary rotor bush (1) to rotate in accordance with the operation of the impact crusher facility The hammer 4 is fixed with the fixing pin 3.

If the hammer 3 is used in an impact crusher facility for a long time and is worn and burned out, the fixing pin 3 must be removed to replace it.

At this time, the hammer fixing pin take-out jig of the impact crusher according to the present invention is to be assembled at the position where the rotary arm (2) and the hammer (4) is fastened by the fixing pin (3).

That is, the configuration of the hammer fixing pin take-out jig of the impact crusher according to the present invention is a pin take-out plate (19a) formed in the center of the hole 17, the fixing pin 3 is taken out and the fixing pin (3) A cylinder fixing plate 19b having a through hole 21 to which the hydraulic cylinder 11 is fixed so that the hydraulic cylinder 11 can be removed, and pin outlining liners 16a and 16b that couple bolts 15 to upper and lower inner surfaces thereof; It consists of upper and lower plates 18a and 18b for fastening the plate 19a and the pin outlining liners 16a and 16b to the bolts 20.

In addition, the upper and lower plates 18a and 18b are fixed to the bolts 20 by being uneven in contact with upper and lower portions of the pin taking-out plate 19a and the pin taking-out liner 16a and 16b, and the cylinder fixing plate 19b The through hole 21 formed in the center portion has a nut processing portion 14 formed on the inner circumferential surface thereof so as to be screwed with the bolt processing portion 13 of the hydraulic cylinder 11.

Hereinafter, the operation of the present invention will be described in detail.

As shown in Figs. 2 to 3 referred to in the above configuration, when the hammer 3 of the impact crusher is worn and burned for a long time and needs replacement, the ring stopper 12 of the fixing pin 3 is removed. The outtake hole 17 formed at the center of the pinch out plate 19a constituting the present invention is positioned to coincide with the position of the fixing pin 3, and then molten iron contacts the upper and lower surfaces of the pinch out plate 19a. The upper and lower plates 18a and 18b are positioned and then fixed together as fastening bolts 20.

As described above, a pair of pin take-out liners 16a may be fixed to the other side of the upper and lower plates 18a and 18b, one side of which is fixed to the upper and lower surfaces of the pinch-out plate 19a. 16b) is fixed to the fastening bolt 20 by the uneven contact.

The cylinder fixing plate 19b is fixed to the side portions of the fixed pair of pin outlining liners 16a and 16b as fastening bolts 15, and at this time, a cylinder through hole formed at the center of the cylinder fixing plate 19b. (21) shall be fixed so as to match the position of the cross section of the fixing pin (3).

A nut machining portion 14 is formed in the inner surface of the central cylinder through hole 21 of the fixed cylinder fixing plate 19b, and the hydraulic cylinder having the bolt machining portion 13 formed therein. (11) is to be fastened, in which case the diameter of the cylinder shaft (11a) of the hydraulic cylinder (11) is to be operated only to be configured to have a diameter that is the same or somewhat smaller than the diameter of the fixing pin (3). .

By operating the cylinder 11 by pressing the operation button 9 installed on the hydraulic pump 8 of the hydraulic cylinder 11 coupled as described above, the hammer fixing pin 3 is safely and simply removed.

When the fixing pin (3) take-out operation as described above is completed by separating and arranging the hydraulic cylinder (11) coupled to the hammer fixing pin take-out jig of the impact crusher according to the present invention, the assembly process and the reverse order The hammer fixing pin of the impact crusher according to the separation jig is to be stored and, because of the separated storage it is easy for the worker to carry and move to the desired position.

As described above, the present invention improves the work force for removing the pin and improves work efficiency by automatically removing the hammer fixing pin automatically and simply in a narrow space during the hammer replacement operation of the impact crusher, and prevents safety accidents. At the same time, since the device is assembled, there is an effect that it is easy to carry and store.
