Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a cable slipping prevention device for preventing a conveyance cable from slipping off from a pulley such as a receiving cable ring (referred to as LX lower cable). It is related to.

(Prior Art and its Problems) Conventionally, conveyance cables have often been detached toward the side opposite to the fixed member of the pulley due to wind force or other lateral forces.

This is because the grip of a conveyed object such as a ski lift or a gondola lift passes through the side of the pulley opposite to the fixed member, so it has been difficult to provide a derailment prevention device on the side opposite to the fixed member.

However, recently, a derailment prevention device (Japanese Unexamined Patent Publication No. 59-29558) as shown in FIG. 19 has been invented.

To explain this, the device (M) is a pulley (
A rotary plate (P) having a plurality of radially extending anti-rope pieces (Pl) is provided on the side opposite to the fixed member of f), coaxially with the pulley (f) and rotatable. , the tip of the rope breakage prevention piece (Pl) is positioned above the conveyance wire cable (S). This prevents the wire cable (S) from coming off in the direction opposite to the fixed member.

Further, when the conveyed object passes, the search guard piece (P+) is pushed in the traveling direction by its grip (y) and rotates to cover the conveyed object, thereby allowing the conveyed object to pass.

And this cable cable (Pl) is connected to the wire cable (
S) and at the same time adjacent to the derobing prevention piece (
Pl) is formed so that it can rotate in both directions of the wire-cable (S).

However, as described above, this device is equipped with a rotary plate (P) that is rotatable with respect to the traveling direction of the wire cable (S), so the biased wire cable (S)
There was a vacancy in the role of 41-year-old Song, who would rotate due to contact with the line and prevent the line from slipping. This device also allows the conveyed object to be held in its grip (
y) 'c, while rotating the rotating plate (P), the pulley (f)
When passing through the pulley, the conveyed object moves toward the side of the pulley (f) opposite to the fixed member due to wind force and other lateral forces, and the horizontal force causes the wire cable (S) to move during the rotation. There was a risk that the rope could be climbed over the rope-break prevention piece (Pl) and the rope could be removed.

(Technical problem to be solved by the invention) The technical problem of the present invention, which aims to solve the above-mentioned problems, is that wind power is used for transporting objects caused by other lateral forces and deviations caused by the movement of wire cables. By preventing the cable from coming off the rope and preventing the grip from moving toward the side of the pulley opposite to the fixed member due to wind force and lateral force acting on the conveyed object when the conveyed object passes through the pulley. be.

(Technical Means for Achieving the Technical Problem) The technical means of the present invention for achieving the technical problems listed below is as follows: The cable prevention plate is located on the side opposite to the fixed member of the cable receiving ring, and is movable up and down so that when the conveyed object does not pass the grip, the lower end is located below the wire cable, and when it passes the grip, it moves in the vertical direction. a stopper, a grip guide piece that is installed on the side of the stopper and moves the stopper in the vertical direction by guiding the grip; 1lj of the conveying cable constituted by a movement prevention means for preventing it from moving toward the opposite side of the fixed member when passing through the
The object of the present invention is to provide a two-rope prevention device, in which the movement prevention means includes an engaging means that engages with a stopper provided at a stopper passing position on the grip soil surface, and a retaining plate that holds one end of the grip of the cable ring. There is a holding means for holding on the fixed member side.

(Function) The conveyance cable is prevented from coming off to the fixed member side and the opposite side to the fixed member by the NQ rope prevention plate provided on the fixed member side of the receiving cable ring and the stopper vertically installed on the opposite side to the fixed member. When the grip of the conveyed object passes through the receiving ring, the stopper is moved up and down by the grip guide piece, the grip of the conveyed object passes, and after passing, the stopper is returned to its original position. .

Further, while the grip is passing, the movement prevention means prevents the grip from moving toward the opposite side of the fixed member of the receiving ring.

(Effects of the Invention) The present invention has the effects described in J. Rido in having the above configuration.

■ By installing an 1B2 rope prevention plate on the fixed member side of the receiving cable ring and a vertically movable stopper on the opposite side of the receiving cable ring, the stopper can be prevented by wind force, other lateral force, wire cable thrust, etc. Since the transport cable is not moved in the vertical direction, it is possible to reliably prevent the transport cable from coming off.

■ By installing a movement prevention means that prevents the grip from moving toward the opposite side of the fixed member when passing through the receiving ring, it is possible to prevent the grip from moving toward the opposite side of the fixed member when passing through the receiving ring. Since it is possible to prevent movement toward the side opposite to the fixed member, it is possible to reliably prevent the conveying cable from being pulled out of the cable while passing through the receiving ring.
