Description

[Detailed Description of the Invention] [Technical Field] This invention is mainly applicable to ski resorts.
b/ relates to a device for moving a pulley that drives or supports and rotates a rope up and down as necessary.

Stops leading to ski lift equipment (motor side, terminal side)
Although there are related documents such as Japanese Patent Publication No. +TRI5A-22732, the number of such documents is not very large. Among them, there is no technical concept that allows the pulley around which the rope is wound to be adjusted up and down by 1 u.

〔the purpose〕

Ski lift equipment is a special cableway stipulated by the cableway regulations, and in order to ensure the safety of users, the effective space between the rope and the ljI'f plane is set at a certain level or more. As a result, if the position of the rope around which the rope is wound is fixed, it is necessary to remove the snow each time the snow accumulates. Furthermore, snow removal near the bus stop can cause a significant change in the level of the ski slope and the level of the boarding area, which can be dangerous.

This invention, instead of securing legal space through snow removal,
It is an object of the present invention to provide a device for simply and reliably adjusting the vertical position of a pulley around which a tab is wound.

〔composition〕

A pulley around which a rope is wound and a beam having a pressure cable device on both sides are attached to the lifting frame. These seven frames are rectangular frames in plan view. On the other hand, a structural frame will be constructed as a support on the foundation of the location where the stop will be installed, and two guide frames will be erected in parallel in front and rear positions (in the direction of the cableway). The angle of upright may be about 10 degrees receding.

The seven elevating frames are fitted into this guide frame, and both are positioned and fixed by a hydraulic cylinder device and a position fixing device W. The hydraulic cylinder device also has a guide frame of one cylinder.
is for suspending the lifting frame from the structural frame, and the position fixing device W is used to suspend the lifting frame from the structural frame.
This is for positioning f with a bottle or the like with respect to the guide frame. Such a device may be provided as a stop for the pulley on the prime mover side, the terminal side, or both.

〔Example〕

The embodiment shown in the figure will be described. Figure 1 shows the terminal equipment at the foot of the station as a stop. A structural frame 2 is constructed on the foundation 1, and guide frames 8, 8 are erected in front and behind the structural frame 2. In this embodiment, it is erected with a receding angle of approximately 10°. Symbol 4 is an elevating frame, which has a frame shape in plan view as shown in Fig. 2, and the above-mentioned fr
+Ia's guide 71 is fitted into the norm 8.8 and is movable up and down as shown by the chain line in FIG. These seven frames are all constructed of I-shaped materials such as H-shaped steel and square steel.

A pulley 6 around which a tl-p 5 is wound is mounted on the central part of the lifting frame 44:1, and in front of the pulley 6, a beam with pressure rope devices arranged on both sides is rotatably attached to the guide 7 frame 8.8. Against r
lJ This is in contact with a guide roller 9 surrounding it and a pressure roller 10. That is, in the embodiment, two guide rollers 9 are used on each side of the prismatic guide frame 3, for a total of 16 guide rollers, and one of the guide rollers 9, which is in contact with the rear surface of one guide frame 8, is a slightly larger and stronger roller. This is a pressure receiving roller 10.

The guide frame 8 is a fixed plate made of a rectangular steel plate with holes provided at regular intervals on the front and rear sides.11. ．．
A pin bracket 12 fixed to the upper surface of the elevating frame 4 and a positioning pin 18 are combined with this to constitute a position fixing device.

Two bin brackets 12 are provided so as to sandwich the fixing plate 11 from both sides, and have insertion holes that match the holes in the fixing plate 11. The positioning pin 18 should be easy to insert and not easily removed, and in the embodiment, one end is bent to prevent removal.

Note that 4. J stopper 1
4 have been killed.

A hydraulic cylinder 15 is installed in front of the horizontal frame of the structural frame 2.
．． 15 is pivotally mounted so as to be tiltable back and forth, and the lower ends of the rods lfl, lf+ are raised and lowered via brackets 17 71. - It is pivotally mounted on the top surface of the frame 4. The stroke of the rod 16 is approximately equal to the vertical movement range of the lift 71/-m 4.

Reference numeral 18 denotes a hydraulic unit disposed in the structural frame z1-, which is connected to the cylinder 15.16 by a pipe and drives and controls the expansion and contraction of the prad 16.16. These (9) materials form a hydraulic cylinder mechanism.

Although the explanation has been given above regarding the end side of the cableway, the same applies to the main two-way side.

[Operation, effect]

The summer 7F facility is used with the elevating frame 4 lowered near the lower end as shown in FIG.

At this time, the rod 16.16 is extended, and the lifting frame is fixed at that position by inserting the positioning pin 18 between the hole of the bottle bracket 12 and the fixing plate 11. As a result, the rope 5 is wound around the lifting frame. The pulley 6 is maintained at a specified height above the ground.

During the winter ski season, it becomes impossible to maintain the above-mentioned specified height due to snow accumulation, and it is necessary to move the pulley 6 upwards at any time.In this case, first, confirm the operation of the hydraulic cylinder mechanism, and then move the lift frame 4. Lift it a little and pull out the front and rear position fixing bins 18.18.

Next, operate the hydraulic unit 18 to move the lifting frame 4,
It is lifted upward along the guide frame 8 alternately or simultaneously. When the target position is reached, the operation of the hydraulic cylinder mechanism is stopped, and the positioning bin 18 is refitted from the bin bracket 12 into the hole in the fixing plate 11 to fix the position of the elevating frame 4.

Since it is not favorable for work safety if the lifting frame 4 is tilted significantly from the horizontal position when moving up and down, a tilt detection device is provided to detect such tilt and stop the operation of the hydraulic cylinder mechanism. Also good.

The reason why the guide frame δ is inclined backward is to correspond to the inclination of the beam 5, so that even if the vertical position of the elevating frame 4 changes, the tension of the U-bub 5 does not change.

As described above, the pulley 6 is raised and lowered, that is, the vertical position is adjusted. Therefore, the present invention has the following effects.

(1) The vertical position of the pulley 6 can be set by inserting and removing the positioning bin and operating the hydraulic cylinder mechanism, eliminating the need for labor-intensive snow removal. In addition, danger to skiers can be eliminated by avoiding depressions from the slope level due to snow removal.

(2) Since the lift frame is raised and lowered along the tj ID frame to raise and lower the pulley, the structure is simple and the operation is reliable.
