Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an intermediate boarding/disembarking device for a lift, in particular, a cable is endlessly stretched over pulleys provided at a starting point and a terminal point, and is circulated, and a carrier is suspended from the cable to carry passengers. This invention relates to an intermediate boarding and disembarking device for a circulation type lift that transports goods, which is equipped with a cable height adjustment device that adjusts the height of the cable at a cable passing point in the cableway line between the starting point and the ending point.

Circulating lifts for transporting passengers are of a type in which a large number of carriers are arranged on cables at approximately regular intervals and operated by circulating in a fixed direction, and are widely used for transporting skiers and the like.

When constructing such a lift in a snowy area, it goes without saying that the past snowfall and snowfall in the area should be investigated in advance and the optimal plan taken into account. However, as a matter of course, it is well known that the amount of snowfall and snowfall varies significantly depending on the year and time of year.

In conventional lifts, passengers are usually boarded at the starting terminal at the foot of the mountain and disembarked at the terminal terminal at the top of the mountain.Also, in lifts that transport skiers, passengers leave their skis on. Since passengers ride on a carrier, the treads at the boarding and alighting stations are usually snow-covered sliding surfaces.

However, since the height of the carrier suspended from the cable is constant, it is necessary to keep the height from the platform tread to the cable almost constant at all times. In order to maintain a constant height of the landing surface made of snow in response to fluctuations in snow, it requires a great deal of effort to remove snow every time it snows.

Furthermore, even if snow is removed, there will still be a height difference between the snow-covered Tsukuda High near the boarding and alighting area and the Tosho High, so it is necessary to create and maintain a ramp to guide passengers to the approach area between them. .

Therefore, not only is it a hassle for passengers to have to go up and down the sloped taxiway, but it is also inconvenient to be unable to ride the lift while snow removal is being carried out, and for the lift operator, it requires a large amount of snow removal labor. In addition, the operation time of the lift was shortened due to the driver stopping, which often resulted in large losses.

In order to alleviate these inconveniences and losses, the inventors of the present invention have developed a structure of a lift terminal that adjusts the cable height by adjusting the pulley height of the lift terminal according to the snow surface height.

However, when adjusting the cable height at a lift terminal used as a boarding/disembarkation area, there is a problem in that the equipment becomes relatively large-scale.

This invention was made in view of the above circumstances, and even if the snow surface changes due to changes in the amount of snow or snowfall, the height of the cable can be easily adjusted up or down to follow this change. A boarding and alighting device that can form a boarding and alighting area at any point along a cable line without requiring the labor and time of snow removal, taxiway maintenance, and maintenance, and which has a simple structure and is easy to install. The purpose is to provide the following.

Corresponding to this purpose, the intermediate boarding and disembarking device of a lift equipped with the cable height adjustment device of the present invention is suspended endlessly between a pulley provided at a starting terminal and a pulley provided at an end terminal. In a transportation lift equipped with a cable that is attached to the cable and a carrier attached to the cable, a boarding area is provided near a cable passing point on the way between a starting terminal and an ending terminal in a cableway line constituted by the cable, In addition, a cable height adjustment device is provided near the landing area, and the cable height adjustment device adjusts the height of the cable to a required height depending on the snow surface or ground surface.

The rollers 24, 2 are rolled on the front surfaces of the rollers 5, 15'.
At 4', both sides of the guide rails 15 and 15' at corresponding positions are clamped and engaged, and transferred.

In this way, the eight guide roller blocks 22
By engaging with the corresponding guide rails 15 and 15' to enable transfer, as will be described later, even if the elevating frame 16 bears an unbalanced load, there will be no displacement or rattling in the left-right and front-back directions. In addition, the structure is such that rotational displacement is not allowed, and only smooth vertical sliding of the elevating frame 16 is allowed.

The vertical movement of the elevating frame 16 is driven by a hydraulic cylinder 28, as shown in FIGS. 2 and 3.

Brackets 30, 30' are fixed to the lower end of the spacer material 2σ' of the elevating frame 16 in a downwardly protruding manner, and the upper end of the hydraulic cylinder 28 is pivotally connected to the bracket 30, 30' by a shaft pin 32.

The brackets 35, 35' are fixedly protruding from the upper surface of the connecting member 14.

In this way, the hydraulic cylinder 28 is connected by piping to a hydraulic unit disposed at an appropriate location, for example, in this embodiment, a hydraulic unit disposed in the staff room 48, which will be described later, and the hydraulic cylinder 28 is operated by operating the power supply of the hydraulic unit. If pressure oil is supplied, the lower end of the rod 33 is restrained, so
The hydraulic cylinder 28 is pushed up, thus achieving a lifting movement of the lifting frame 16.

Moreover, if the pressure oil in the hydraulic cylinder 28 is returned to the oil tank of the hydraulic unit, the elevating frame 16 can be lowered.

Next, as shown in FIG. 2, FIG. 3, and FIG. Brackets 37, 37' projecting downward are fixed near the free ends of the brackets.

In addition, a balance beam 39 having both ends as free ends and pivoting around the center point of the bracket is rotatably pivoted to the bracket (37, 37') via a shaft pin 38.

Further, near both free ends of the balance beam 39, brackets 41 and 41' are fixed equally on the left and right sides with respect to the center of the elongated body of the balance beam 39, respectively.

A cable receiving device 43 is pivotally attached to the bracket 41, 41' via a shaft pin 42 so as to be freely swingable.

The cable receiving device 43 is as shown in FIG.
A compound beam 44 is swingably pivoted to the compound beam 44, two wheel beams 46, 46' are swingably pivoted near both free ends of the compound beam 44 via shaft pins 45 and 45', respectively. Each two wheel beam 46.46'
A receiving cable ring 7 is rotatably pivotally connected to both ends of the cable via shaft pins 47 and 47', respectively.

Such cable receiving devices 43 are arranged equally on both the left and right ends of the balanced beam 39.

When the cable 3 is supported with urea by the cable receiving ring 7 of the cable receiving device 43 configured in this way and tension is applied to the cable 3, the balanced beam 39
Due to the balancing action of both cable receiving devices 43, the wheel weight loads carried by each receiving cable ring γ are balanced according to the direction of the front and rear cables so that the loads are approximately equal.

Next, as shown in FIG. 2, an attendant's room 48 for an attendant engaged in guiding passengers of the lift, etc., is suspended and fixed to the horizontal members is, is' of the lifting frame 16.
When the elevating frame 16 is raised or lowered according to the snow surface height, or the same height as the ground surface, the staff room 48 is also raised or lowered at the same time.
If the floor height of No. 8 is the same as the snow surface height, it will always maintain a suitable position with respect to the same height as the ground surface.

Next, the configuration of an intermediate getting on/off device using the cable height adjustment device configured as described above will be explained.

In the case of the embodiment shown in FIG. 1, the cable height adjustment device 8 is arranged along the upline side cable towards the top of the mountain at the midpoint between the starting terminal 2 and the support column 6, and The nearby area is a boarding area (in this embodiment, a boarding area).

That is, the cable height adjustment device 8 is installed upright on the outside of the circulation of the cable 3, the arm 36 is extended in the direction of the circulation inside of the cable 3, and the above-mentioned balance beam 39 and cable receiving device 43 are used to control the cable. The rope 3 is guided and the snow surface near the installation point of the rope height adjustment device 8 is formed into a substantially flat surface to form the area of the boarding area 9.

Passengers enter the boarding area 9 in the direction of the arrow 50 and board the carrier 4.

In conventional normal lifts, terminal 2 is generally used as a boarding/disembarkation area, but when using the intermediate boarding/disembarking device according to the present invention, terminal 2 is not used as a boarding/disembarkation area in principle.

However, when snow conditions and other conditions are appropriate, Terminal 2 can be used as a boarding and alighting area, and intermediate boarding and alighting area 9 can be used.
Of course, it is also possible to do so.

In addition, as another embodiment, as shown in FIG.
It is also possible to extend the effective length of

Note that if the cable is adjusted using a cable height adjustment device, there will be slight fluctuations in the length of the endless cable Φ circulating at zero lift, but in normal lifts, the pulley at either the starting point or the terminal terminal Generally, the cable is installed so that it can slide back and forth, and the cable is balanced with a weight or the like so that the cable tension does not become excessive due to the forward or backward movement of the terminal pulley. Variations in the length of the cable caused by the element are sufficiently absorbed and do not pose a problem.

Furthermore, in the embodiment described above, the elevating frame 16
A hydraulic cylinder 28 is used as a driving device for raising and lowering the cylinder, but instead of this hydraulic cylinder,
Of course, any drive device such as a screw jack or an electric screw pusher using a screw and an electric motor can be used.

As explained above, in this invention, the height of the cable is adjusted at any point along the cable, and the vicinity thereof is configured as a boarding/disembarkation area, so that the snow surface changes due to changes in the amount of snow. However, since it does not require the effort and time to remove snow at the landing area, clear the taxiway, and maintain it, it has the following advantages and effects.

(b) Lift operators are freed from the heavy work of snow removal operations, and it is effective in saving labor.

(b) Since the maintenance time required for snow removal, etc. is shortened, the time during which passengers cannot respond to transport requests is shortened, and the inconvenience to passengers is reduced.

(c) Downtime for the above-mentioned maintenance can be shortened, and the operational efficiency of the lift can be increased.

(2) There is no difference in height between the snow surface near the boarding and alighting area and the snow surface at the boarding and alighting area, and they are on the same level, making it easier for passengers to board and alight, which is advantageous in terms of safety.

Furthermore, in the method of adjusting the cable height by moving the pulley up and down at the terminal, the pulley lifting equipment must be relatively large-scale, but this invention requires relatively small-scale equipment. The cable height can be easily adjusted.

(f) If the staff room 48 is suspended from the elevating frame 16, the floor surface of the staff room can be automatically adjusted to a height that matches the height of the snow surface.

Further, according to the present invention, in addition to using the cable height adjustment device 8 from the beginning, in an existing lift in which the pulley height is at a fixed position, the cableway line near the terminal can be used without modifying the structure of the terminal. It is also possible to install the additional 77D at the 0 elapsed point or any intermediate elapsed point.

Furthermore, in addition to lifts exclusively for winter mountain use, which are mainly used by skiers, there are also lifts that are used for both skiers in the winter and mountain climbers in the summer.
The intermediate boarding device or the cable height adjustment device according to the present invention can also be used when adjusting the cable height depending on the snow surface and the ground surface in this dual-purpose lift.

In the embodiment described above, the present invention is applied to a lift using a chair-type carrier, but it is also possible to transport passengers wearing skis by towing them while sliding on the snow surface along the lift track. Of course, the present invention can also be applied to a sliding sliding lift.
