Description

Master Pin Remover {MASTER PIN REMOVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a master pin remover, and more particularly, to a master pin remover capable of easily and quickly performing a series of operations for separating or fastening a master pin from an endless track regardless of proficiency.

In construction heavy equipment such as an excavator, an infinite orbit is typically mounted as a means of movement underneath.

5, a plurality of (approximately 38 to 54) track links 30 each having a shoe are connected by pins (master pins) to form one chain, And a track link of one end and a track link of the other end are finely connected to each other by a bushing and a master pin in a heavy equipment so as to exhibit a function as an endless track.

The shoe 7 and the track link 10 are made of a combination of normal bolts as shown in Fig.

On the other hand, as is well known, in order to carry out the maintenance of an infinite track, that is, to replace or repair a track composed of a combination of a track link and a shoe and its surrounding parts (sprocket, upper and lower rollers, etc.) do.

Then, after removing the master pin, the track is separated from the heavy equipment. Then, after maintenance, the master pin is inserted and the track is reassembled and used.

In other words, the track must be separated for heavy equipment, equipment repair or parts exchange, and the master pin must be pulled out of the track link and removed from the track link in order to separate the track.

However, in the above operation, the operator uses a handmade hammer, a hemmer, and a pin member to move the pin member close to the master pin inserted in the track link, and then hammers the master pin to remove or insert the master pin.

Such a process is not only a very difficult operation, but also has a problem that frequent safety accidents occur due to members having a heavy load during operation.
