The pintle chain attachment device 10 according to an embodiment of the present invention may be classified into a front link unit 110 and a rear link unit 120 and a flight 130.

Although the pintle chain attachment device 10 of the present embodiment can be manufactured in various ways, it is generally preferable to form the overall shape by a casting process and to form the shape afterwards.

As shown in the pintle chain attachment device 10, the front link unit 110 and the rear link unit 120 are formed before and after the lower end, respectively. In addition, each of the front link unit 110 and the rear link unit 120 is formed with a front link pin hole 110h and a rear link pin hole 120h for coupling the chain link 20, respectively.

Therefore, in this embodiment, the front link unit 110 and the rear link unit 120, the roll gear 5 for the rotation of the chain 1 to be formed in the form of a chain link 20 constituting the chain (1) The center is empty so as to insert the teeth 50 of the cross-section, and crosses the rotation direction of the chain 1 to pin the rear end of the front chain link 20a and the front end of the rear chain link 20b, respectively. The front link pin hole 110h and the rear link pin hole 120h are formed.

And the flight 130 is located in the center of the pintle chain attachment device 10 of the present embodiment. In addition, the front link portion 110 and the rear link portion 120 is formed in the center of the roll gear 5 is inserted, and are connected to each other to form a body.

The chain 1 is formed by continuously connecting the general chain link 20 and combining the attachment device 10 of the present embodiment in which the flight 130 is formed at a required position. Therefore, the chain 1 may be formed in the form of coupling the attachment device 10 between the two to three chain links 20, connecting a plurality of chain links 20 long, such as 20-30 stages It is possible to form the chain 1 in various forms, such as to form the attachment device 10 in the next stage.

In addition, such a coupling is to form a chain (1) by fastening using the coupling pin 15 shown in FIG. As shown, the coupling pin 15 of the present embodiment can be largely divided into a pin head 15a and a pin stand 15b, and a pin hole 15h is formed in the pin stand 15b. In addition, the pin head 15a is formed with a coupling groove 15k such that the coupling pin 15 itself is not rotated after the coupling pin 15 is fastened and the fixing state is firm. The coupling is also performed outside the rear link pin hole 120h. Coupling protrusion 120k is formed to engage with groove 15k.

Thereafter, when the chain link 20 is positioned at the time of coupling, the coupling pin 15 is connected to the front coupling pin hole 110h and the rear end with the coupling groove 15j of the coupling pin 15 fitted to the coupling protrusion 120k. After inserting into the link pin hole 120h, a pin (not shown) is inserted into the pin hole 15h so as to be firmly coupled so that the chain 1 is not separated.

Therefore, when the completed chain 1 is rotated by the roll gear 5, the flight 130 is in the form of a plate protruding in the outer circumferential direction with respect to the chain composed of the combination. In addition, in the present embodiment, as many as necessary, two mounting holes 130h are formed in the flight 130, and the necessary work is carried out through the process of combining with wires, ropes, screws, bolts, nuts, and the like. To mount a tool or instrument to

In the pintle chain attachment device 10 of the present embodiment, as shown by the thick arrow, the lower end thereof is convexly concave upward (the outer circumferential direction of the chain), so that the flight groove 131 is formed.

This seems to be a small part, but it is important.

As described above, the flight 130 is mounted with tools or instruments for the work to be performed.

As an example, as shown in FIG. 5, when using the chain 1 combined with the pintle chain attachment device 10 for sludge operation, the chains 1 are respectively connected to two roll gears 5 spaced apart from each other. In this flight 130 is coupled to each chain (1), as shown in the drawing, as a tool or a tool for work in general, the working plate (7) or each piece of wood tied or entangled (attached) Will be used.

Accordingly, when the two roll gears 5 are rotated to operate, the working plate 7 mounted on the flight 130 of each chain 1 rotates and scratches the bottom of the river, thereby removing the sludge from the floor. Will be able to move.

The teeth 50 of the roll gear 5, which takes great force in this process, are not only rotated themselves, but also scratched, worn, lost and deformed due to uneven rough and bad working conditions with many wastes and sludges. Insertion between the 110 and the rear link portion 120 is often not good.

Due to such a bad work, the teeth 50 of the roll gear 5 may be caught in various reinforcing bars, shreds, and twigs. If the roll gear 5 continues to rotate in such a situation, the teeth 50 may be caught. Objects often act as a factor to expel and lose flight 130.

However, the shape of the roll gear 5, in particular the teeth 50, is changed due to prolonged use, which often causes damage to the chain 1, especially the flight 130, causing many problems. In particular, among the flight 130, the lower end portion of the gear 50 of the roll gear 5 is rotated to cause more damage than other parts.

Eventually, if the flight 130 is lost due to various unfavorable conditions, the flight 130 that cannot be used must be replaced in the chain, resulting in a lot of time and economic losses.

In the pintle chain attachment device 10 of the present embodiment, the structure is formed in the same manner as described above, thereby eliminating such problems in one place, increasing work efficiency and eliminating conventional time and economic losses.
