Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous conveyance device for a long chain in a tempering strain relief furnace.

In other words, during the manufacturing process of long chains for ships or offshore structures, tempering distortion can be suitably and efficiently removed by sequentially moving multiple chains into a dedicated furnace, and multiple chains can be removed at once. If each trolley is made into an endless and caterpillar type structure, and multiple long chains can be reliably supported and transported, continuous work can be carried out with smooth circular rotation. The aim is to provide this information so that you can perform it well.

Next, the embodiment shown in the drawings will be described.

B shows a furnace dedicated to tempering strain relief, and when a chain curtain 2 is hung at the entrance 1, a chain curtain 2 is also hung at the outlet 3.
' is installed vertically, and is equipped with a burner 4, an exhaust port, an intake port, etc., and has equipment such as a cold air inlet, a hot air circulation fan, and an exhaust pipe on the outside, and has a high temperature of 600℃ to 900℃ in the central part. Configure it so that

Additionally, three rails 6, 6' are provided on the floor 5 in the furnace B from the starting end A in front of the inlet 1 to the terminal end outside the outlet 3.
, 6'' are laid in parallel, and a passage 7 is extended below the rails 6, 6', 6'' from below the starting end A to below the terminal opening, and parallel to both sides of the passage 7. Rails 8, 8' are extended by brackets 9, 9', and a driving wheel 10 and an idler wheel 11 are mounted on both ends of the passageway 7 below the mouth.

C is a long chain, which is used for ships or offshore structures, and is constructed by connecting links loaded with scuds.

A is a trolley, which is short in length in the front and back direction and has a width that allows four long chains C to be placed side by side, and side plates 12, 12 are extended on both sides to prevent them from falling off. , mating bracket portions 13 at the front and rear lower portions of both connected bogies A, A,
Wheels 14, 14', 14'' are installed on both sides and the center of the wheel 13, and a chain link 15 is successively installed across each of the wheels 14, 14', 14'' in the front and rear direction.
, 14' are rotatable on the rails 6, 6'' and 8, 8', and the rollers 14'' are rollable on the rail 6', and each bogie A is connected in an endless caterpillar structure to the drive unit. It is constructed so that it can be rotated by being wrapped around the wheel 10 and the idler wheel 11.

In the figure, 16 is a guide roller, 17 is a charging guide roller, 18 is an extraction side guide roller, and 19 is a slack detection limit switch.

Therefore, each cart A moves in the direction of arrow A in a daisy chain by the chain link 15 that is driven around the drive wheel 10 and the idler wheel 11, and the cart A entering the furnace A from the starting end A rotates at each turn. Wheels 14, 14'14'' are rails 6, 6''
, 6', respectively, and is reversed by the idler wheels 11 at the terminal end.
4' rolls on the rails 8, 8' and moves in the direction of the arrow in the passage 7, and then returns to the starting end A and circulates.

Then, the four long chains 0, which have been hardened and connected with links in sequence, are lined up and fed out by the loading guide roller 17, and then placed on the cart A, which is facing the entrance 1 while being reversed. , they are placed on the trolley A one after another in a state where they are continuously unwound and fed into the furnace B by the trolleys A, A.

The tempering strain relief effect is performed by heating in the dedicated furnace B, and this effect is suitably performed at a high temperature of 600° C. to 900° C. in the central portion of the furnace.

When the continuous carts B are taken out from the exit 3 to the outer end port, the four long chains are guided by the guide rollers 18 on the extracting side and are pulled out as finished products.

In this way, the present invention connects each of the carts A in an endless, caterpillar-type structure, and continuously loads a plurality of long chains C on each cart A at the starting end A of the tempering strain relief furnace B. Since the configuration is such that each trolley A is sequentially reversed at the terminal end port and then circulated and rotated to the starting end section A while being continuously transferred inside the N furnace, it is possible to carry long chains such as those for ships or offshore structures. In the manufacturing process, multiple pieces are continuously manufactured using dedicated furnace B.
It is possible to suitably and efficiently remove tempering strain while sequentially moving the rods, and each trolley A that supports and continuously transfers multiple rods at once is made into an endless and caterpillar structure to ensure reliability. If the support and anchorage can be carried out, both parts can be rotated smoothly and continuous work can be carried out smoothly.
