Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an overhead cableway for transporting cargo, and more particularly, to an overhead cableway for transporting cargo in which the main rope and the cable are arranged in the same vertical plane. .

<Prior Art> Conventionally, as an example of this type of overhead cableway transport, there is one disclosed in Japanese Utility Model Publication No. 4539/1983, as shown in FIG. 8, for example.

In this device, the upper part of the hanging rod 2 is rotatably installed in the center of the wheel frame 3 where the guide wheels 5, 5 that run on the main rope are arranged.
By providing the gripping member 13 for gripping the good plan c on the suspension rod 2, the suspension rod 2 is always kept vertical regardless of the inclination angle of the main rope.

However, as shown in Fig. 8, when the carrying out a passes through the saddle d provided on the support, it is gripped, placed at 91, 1, -1≠-, ^, j, guard, L. −Police−↓Fma↓
j = Since it is necessary to install the member 13 with a space between it and the lower surface of the saddle d, it is necessary to allow a length for the suspension rod 2 to pass through the saddle, and this length is determined by the angle of inclination of the saddle d. The larger it gets, the longer it becomes, and eventually the entire length of the hanging rod 2, ie, the length from the pivot point 2' of the hanging rod 2 to the lower end on which the transported object e is hung, becomes longer.

Therefore, in the case of FIG. 8, when the hanging rod 2 swings, the conveyed object e
It was shaking a lot and it was dangerous.

In addition, in the case of FIG. 8, the gripping member 13 is provided directly on the hanging rod 2, so the hanging rod 2 swings due to the traction force of the good plan c.
The conveyed object e was easily shaken.

<Problems to be Solved by the Invention> A problem to be solved by the present invention is to shorten the length from the pivot point to the lower end of the hanging rod.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to rotatably provide guide wheels that run on the main ropes at the front and back of the upper part of the support frame, respectively. At the center of the lower part of the frame, the center of the mounting member and the upper part of the suspension rod are separately provided so as to be freely rotatable in the direction of the main rope, and gripping members for gripping the good idea are provided at both front and rear ends of the mounting member, respectively, in the direction of the good idea. It is rotatably provided.

<Function> The present invention provides the following features:
By locating the center of the mounting member and the upper end of the suspension rod, problems with the mounting member provided with the front and rear guide wheels and the front and rear gripping members can be kept to a minimum regardless of the inclination angle of the saddle, and the mounting member can be rotated. This prevents the strong changes in the tow rope caused by the movement of the carrier from being applied to the support frame, and by rotating the front and rear grip members, the portion of the tow rope near the grip member caused by the weight of the tow rope is prevented. This eliminates the curvature.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings. In the drawings, a is a carrier, b is a main rope, and c is a tow rope.

The carrier a is composed of a support frame 1 and a hanging rod 2. The support frame 1 is provided with wheel frames 3 on both front and rear sides of its upper part so as to be rotatable in the direction of the main rope b.

A guide wheel 5 is rotatably attached to the wheel frame 3 via an axle 4, and the guide wheel 5 engages on the main rope b.

Reference numeral 6 denotes a support member that is fixed to the lower part of the support frame 1 and hangs down, and a hanging rod 2 is attached to the lower end of the support member.

The upper end of the suspension rod 2 is pivotally attached to the support member 6 via a pivot 7, and is swingable back and forth in the direction of movement of the carrier a.

A hanging hole 8 is drilled at the lower end of the hanging rod 2, and a U-shaped rod 9 and a lobe 10 are hung in the hole 8, and a conveyed object e is hung thereon.

Reference numeral 11 denotes a mounting member provided on the side surface of the support frame 1 opposite to the wheel frame 3, and the center of the upper end of the mounting member 11 is rotatably mounted and supported on a support shaft 12 fixed to the support frame 1 and the support member 6.

Therefore, the center of the mounting member 11 and the upper end of the hanging rod 2 are arranged on a line that is perpendicular to the line connecting the axles 4, 4 of the front and rear guide wheels 5, 5, and as shown in FIG. When passing through the saddle d provided in the front and rear guide wheels 5,
The axis line connecting the center of the line connecting 4 and the center of the mounting member 11 is
It always extends toward the center of curvature f of the saddle d, and the dimension between these two is kept to a minimum regardless of the inclination angle of the saddle d, and the length from the pivot point 2'' of the suspension rod 2 to the lower end is kept as short as necessary. It can be done.

Reference numerals 13 and 13 designate tow ropes c at both the front and rear ends of the mounting member 11, respectively.
These are a pair of gripping members rotatably provided in the direction, and the member 13 grips the tow rope c with two gripping pieces 14 and 15.

Therefore, when the carrier a is located in the center between the columns and the same amount of tension is applied to the front and rear gripping members 13, 13 as shown in FIG. Only the gripping members 13, 13 rotate as the towline c between the front and rear gripping members 13, 13 extends and follow the inclination of the towline c, respectively, and the gripping member 13 is rotated by the own weight of the towline c. Prevent the towline c near the towline c from bending excessively.

Also, as shown in FIG. 6b, when the carrier a moves, the magnitude of the tension applied to the front and rear gripping members 13, 13 at positions other than the center between the supports. When the same amount of tension disappears, the mounting member 11 is rotated to the side with the greater tension so that the same amount of tension is applied to the front and rear gripping members 13, 13, so that no bending force is applied to the support frame 1, and As the towline c between the front and rear gripping members 13, 13 is extended, the front and rear gripping members 13, 13 rotate following the inclination of the towline c, respectively, and the towline c near the gripping member 13 becomes extreme. Avoid bending. Next, FIG. 7 shows a case where a long object is transported, and in this case, two transporters A, . A'' is suspended from the main rope b at appropriate intervals, and a long object is suspended horizontally across the hanging rods 2, 2 of both carriers A and a''.

<Effects of the Invention> Since the present invention has the above configuration, it has one of the following advantages.

1. By arranging the center of the mounting member and the upper end of the suspension rod on a line that is perpendicular to the line connecting the wheels of the front and rear guide shafts, the mounting member provides the front and rear guide wheels and the front and rear gripping members regardless of the inclination angle of the saddle. Since the distance between the two is kept to a minimum, the length from the rotation point of the suspension rod to the lower end can be made as short as possible compared to the conventional suspension rod that allows for the length of the saddle to pass through.
The conveyed object can be transported safely without shaking significantly, and there is no gripping member on the suspension rod), so the traction force of the tow rope does not act directly on the suspension rod, unlike conventional models, and the conveyed object does not shake. Can be transported.

2. When the tension of the tow rope changes as the carrier moves, different magnitudes of tension are applied to the front and rear of the gripping member, and bending force is applied to the entire carrier. However, the aerial cableway carrier of the present invention has a support frame. Since the mounting member is rotatably provided, the mounting member rotates so as not to apply an equal amount of tension to the front and rear gripping members, and no bending force is applied to the support frame.

3. Due to the weight of the towline, the towline near the gripping member was partially bent to an extreme degree, and the load was applied to the towline and the gripping member, potentially damaging them. As the tow rope between the front and rear gripping members of the carrier extends, the front and rear gripping members respectively rotate following the inclination of the tow rope, preventing the tow rope from bending and damaging the tow rope and the gripping members. It can be prevented.
