する。However, in the case of manual tail picking work, even if a tangled portion comes while the wire rope is being drawn out, it can be dealt with immediately. However, if the tail handling work is left to the tail wire operating device according to the above invention, the entangled part of the wire rope that is being fed out may be caught at the entrance of the operating device, which may damage the device and lead to a serious accident. Therefore, he had to set up a watchman and be alert. It is an object of the present invention to develop a safety device capable of automatically stopping a winch and ringing a horn when a tangled portion of a wire rope is caught at an entrance.

処置を取る事が出来る。The safety device of the present invention is attached to the entrance of the wire rope introducing pipe of the tail picking device, and detects and transmits when the entangled rope comes to the entrance. That is, a slidable movable tube was fitted around the inlet of the introduction tube so that the entangled rope could be caught in the movable tube before it was caught in the introduction tube.
Since this movable cylinder always extends outward from the inlet of the introduction pipe by the coil spring, when a tangled rope catches on this, the spring is compressed and retracts along the introduction pipe. This causes the detection switch to transmit. You can take an emergency measure such as sounding an alarm by calling or stopping the winch.

First, FIG. 1 will be described. The wire rope introducing tube 1 of this embodiment is not a winch tail handling device but a part of a separately manufactured safety device. The attachment portion 1b at the rear end of the introduction tube 1 is connected to the wire rope receiving port of the tail picking device 2 as shown in FIG. However, this connecting means is arbitrary. As shown in FIG. 1, a straight cylindrical portion is provided in the vicinity of the inlet of the introduction pipe 1, and a movable barrel is axially slidably fitted therein. Spring receivers 4 and 5 are welded and fixed to the introduction pipe 1 and the movable cylinder 3, respectively, and are biased by a coil spring 6 between the two in a direction to push them apart. Therefore, the movable cylinder 3 tends to extend outward from the introduction pipe 1 by a large amount.
Is stopped at the fixed position shown in the figure. The restraint material may be replaced with a string or a fixed stop piece.

The required distance means a distance sufficient for the detection operation. The entangled portion W '(Fig. 1) of the wire rope W being fed out is the movable cylinder 3
The movable cylinder 3 pushes the coil spring 6 and retracts. The spring stopper 5 of the movable cylinder 3 also retracts the one stopper 7a having the bolt head welded thereto. When the rear end of the restraint member 7a moves backward to the position where the detection switch 8 is pushed, the switch 8 transmits, the solenoid valve 9 in FIG. 2 is switched, and the winch 1
The safety valve 11 of 0 is opened and the supply of hydraulic pressure to the winch 10 and the tail picking device 2 is stopped, so that it immediately stops.

ず、ほかの構造のものであってもよい。Alternatively, the detection signal can be used freely by, for example, sounding an alarm with the detection switch 8 so that the winch driver can take emergency measures. In the above embodiment, one bolt end of the stopper material between both spring supports also serves as the detection switch operating end, but of course, the stopper is dedicated to it, and even if the detection switch operating body is attached to a member that moves together with the movable cylinder 3. Good. The detection switch may be a non-contact type, and the type and mounting method are left to the designer. In addition, it goes without saying that the present invention can be variously changed and applied according to the implementation conditions without changing the gist of the present invention. Further, the winch tail handling device is not limited to the above-mentioned Japanese Patent No. 1579211 of the present applicant, and may have another structure.

名が不要になる。[Effects of the Invention] During the wire rope payout, there is a entangled portion that may be caught at the inlet of the tail picking device and a light entangled portion that can be untangled and accepted. According to the present invention, the reaction force of the coil spring 6 gradually increases as the movable barrel 3 moves backward after the entangled portion is caught in the movable barrel inlet 3a. Due to the increasing reaction force, if it is a slight entanglement, it can be unraveled and enters the introduction tube, and only when it cannot be unraveled, the movable cylinder 3 continues to retreat and transmits a detection switch. That is, the movable barrel 3 of the present invention selects the entangled portion softly. Since the safety device of the present invention can be manufactured in a well-organized manner, it can be easily attached to the existing tail handling device or the tail handling part of the winch. Since the winch winding cap (capstan) is usually a double cylinder, the application of the present invention allows the entanglement observer 2
