Abstract

The present invention is a structure in which a separate loaf is fixed to the drum (1) with two stems, and each end is fixed and the opposite end is fixed to the balancer (2);
The separate loaf is a re-ropping method of a separate loaf that supports the load on the hanging mechanism 112 on the other side and minimizes the tilting impact on the balancer 2 when a cutting accident occurs in one of the lofus. It is a stopper device of the spring balm (3).

Description

Preparative Device for Cutoff Accident of Crane Lifting Rope}

According to the present invention, a plurality of stems (4, 5) are separated between the sheave (6) and the sheave (10) of the trolley hanger (112) wound on the drum (1) of the trolley (101) of the overhead crane. A device of a spring stopper that buffers the instantaneous impact of the Lopu Balancer 2, which stops the load from falling on the moon mechanism when an accident occurs in which one of the loafs is cut in the hoisting loafers connected in multiple layers. to be.

In the present invention, the ends of the two stems are fixed to the grooves of the drum 1 in the relative twist of the S-twist and Z-twist, respectively, and the sheave 6 and the treve 10 of the trolley 112 are fixed. Separately nutrients (4, 5) to the living (Reeving) and fix the two ends (11, 12) at each end of the balancer (2). The two wire ropes are divided into two parts and the load of the delivery mechanism 112 is loaded. Therefore, when one loaf is cut, its equal load is directed to the other loaf.

In the design of the Rofu, the Rofu is selected with a margin of 5 times or more for the Minimum Breaking Load, so even if either (4 or 5) Rofu is cut, the other side receives 2.5 times the margin of the Rofu Shear Load. Will have

As described above, the balancer (2) is cut when either one of the ropes is cut in a seesaw structure in which the load of the hanging mechanism 112 balances the tension of the ropes due to the load divided by the two groups of ropes. It is a task for the stopper 3 to cushion the instantaneous tilt shock and stop the tilt.

In the present invention, the balancer 2 is adjusted to balance the tension of the tensioning force in which the two independent lofus 4 and 5 separately behave when lifting the load. However, when a cutting accident occurs in one loaf, the shock absorber is absorbed by installing a spring bumper 3 under the balancer in order to cushion the shocks on the other loaf.

When installing the wire rope with a single stem, one of the "S" or "Z" twists is selected. At this time, the twisted wire is loosened and the lug mechanism 112 rotates in the twist direction of the rope. There may be a phenomenon.

In the present invention, since the two strands are equipped with a loaf of relative (S, Z) twist, the deflection of the deflection is eliminated. In addition, the structure that Lofu independently lived in two trunks is a device to prepare for Lofu accidents. The living structure is shown in the reference diagram of FIG.

Fig. 5 is a relational view of the shock absorbing spring bumper, and Fig. 6 shows the entire living of the lofu formed with the peripheral device related to the lofu. Fig. 7 is a reference diagram fixed as a stem rofu without measures for cutting of rofu.

When the moon mechanism 112 is separated from the trolley 101 by two separate groups of hoisting loafs of the up-and-down behavior of the connection, the seesaw device having a function of compensating for the balance of tension between the separate loafs and the loads. It consists of a balancer (2).

Detailed description of the present invention relates to a stopper (3) of a spring shock absorber for mitigating the instantaneous impact of the slope of the opposing lofu on the balancer (2) when either loaf of the two groups is cut. will be.
