Description

Self-driven elevator with single mast structure that does not require machine room and hoistway structure {ROPE AND SINGLE MAST TYPE CAR SELF-DRIVING LIFT HAVING TWIN CAR WITHOUT MACHINE ROOM AND HOISTWAY STRUCTURE}

The present invention relates to a rope-type twin-type self-driven elevator with a single mast structure that does not require a machine room and a hoistway structure. It is a rope-type twin-type self-driven elevator with a single mast structure that eliminates the need to install a machine room, allows the control panel to be separately installed on the vehicle itself or at any location, and eliminates the need to build a separate vehicle hoistway structure. it's about

In general, an elevator is installed in a high-rise building, etc. to transport people or cargo to a desired floor while ascending and descending in a vertical direction.

Such an elevator can be divided into a machine room upper type in which a hoisting machine and a control panel are provided on an upper part of a hoistway, a machine roomless type in which a hoisting machine and a control panel are installed on a hoistway or a guide rail, and the like.

And, in the building where the elevator is installed, a hoistway structure for the boarding car to go up and down is essentially provided.

1 is a view showing an example of a conventional elevator in which the passenger car door is arranged in the front and rear directions, a passenger car 10 for boarding or loading cargo, and a passenger car 10 provided in front of the boarding car 10 Connecting the front car door 14 and the rear car door 15, the counterweight 40 for maintaining a weight balance with the boarding car 10, and the boarding car 10 and the counterweight 40 It is configured to include a wire rope (W), and a traction sheave (Traction Sheave) (20) for elevating the boarding car (10).

The traction sheave 20 is installed together with a control panel in a machine room or a hoistway structure at the top of a building, and elevates the boarding car 10 while rotating in forward and reverse directions.

In addition, two boarding car sheaves (S1, S2) are provided on the upper surface of the boarding car 10, and the counterweight sheave (S3) is provided on the upper surface of the counterweight (C).

In the elevator of the above structure, one end of the wire rope (W) is fixed by a rope fixing part (F1) provided in the machine room above the boarding car 10, and is sequentially roped in S1 → S2 → traction sheave → S3 Then, the other end is fixed to the rope fixing part (F2) in the hoistway structure.

The wire rope (W) wound around each sheave is usually used in several strands, the number of strands of the wire rope is increased or decreased according to the load load of the elevator.

When the traction sheave 20 is rotated forward and reverse in the elevator having the above structure, the boarding car 10 goes up and down along the hoistway structure, and the counterweight 40 goes up and down in the opposite direction to the boarding car 10 do.

On the other hand, Figure 2 shows another example of the conventional rope-type elevator.

The conventional elevator shown in FIG. 2 includes a driving unit 31 for driving a traction sheave 31a on which a wire rope W is wound, an intermediate sheave 33 for guiding the wire rope W, and a boarding car ( 10) A control panel 32 for controlling the lifting and lowering is installed inside the machine room 30 provided in the upper part of the hoistway P.

However, the conventional elevator should have a separate machine room 30 for installing the driving unit 31 and the control panel 32 in the upper portion of the hoistway P.

Accordingly, there are disadvantages in that the construction cost increases and the installation time of the elevator is delayed.

In addition, when a construction elevator is temporarily installed to transport workers and equipment at various construction sites, it is difficult to raise or lower the height of the elevator due to the machine room 30 provided on the upper part of the hoistway (P) There is a problem. .

As a method for solving the above problems, the present inventors have proposed a machine roomless (Machine Room Less) elevator without a machine room as shown in FIG. 3 .

In the conventional machine roomless elevator shown in FIG. 3, the driving unit 31 for driving the elevator is installed on one side of the upper side of the guide rail (not shown), and the control panel 32 is installed on the side of the hoistway wall. will be.

According to the machine roomless elevator described above, there is an advantage that it is not necessary to provide a separate machine room in the upper portion of the hoistway (P).

However, the conventional machine roomless elevator is difficult to install when it is difficult to secure a driving unit installation space in the upper part of the hoistway (P).

In addition, when it is necessary to adjust the operating height of the elevator, there is a disadvantage in that it cannot actively respond.

On the other hand, in the construction of a high-rise building, a lift for construction is used to transport workers and various building materials to a required floor, and FIG. 4 shows an example of such a conventional lift for construction.

The conventional lift (L) for construction, as shown in FIG. 4, is installed on one side of the mast structure installed in the vertical direction, and transports workers, materials and equipment to the required floor.

The mast (M) structure is installed by assembling a plurality of mast units in a vertical direction, and when increasing the height of the mast structure, a new mast unit is additionally assembled.

That is, by assembling a new mast unit on top of the top mast unit, the height of the mast structure is gradually increased.

On one side of the mast (M) structure, a rack (Rack) 11 is installed, and the lift (L) is provided with a pinion gear (Pinion Gear) 12 corresponding thereto.

With the above structure, it is possible to drive the pinion gear 12 so that the lift L rides the rack 11 up and down.

However, the conventional lift for construction using a rack and pinion has the following problems.

First, it generates a lot of vibration and noise, cannot operate at high speed, and has frequent breakdowns.

That is, in the conventional lift, since the pinion gear rides up and down on a rack, a lot of vibration and noise are generated in the process of contacting the gears, and the maximum speed is only about 60 m/min.

Accordingly, it takes a lot of time to transport a large number of workers and materials, and construction is often delayed due to frequent breakdowns of lifts.

This problem becomes more serious in the case of a high-rise building construction site where a large number of workers and materials must be supplied.

Second, there is a limit to increasing the capacity of the lift.

That is, in the conventional lift, since the pinion is raised and lowered on a rack, it is difficult to manufacture with a capacity of about 3 tons or more.

Accordingly, the conventional lift can only board a small number of people, and it is difficult to transport heavy construction materials or equipment.

To solve this, a tower crane is installed on the upper part of the mast (M) structure to lift large and heavy materials, and in this case, the construction cost is greatly increased.

Third, there is a high risk of safety accidents occurring during the lift process, and in case of an emergency, a large number of workers in high floors cannot quickly evacuate to the ground.

That is, since the conventional lift for construction is temporarily installed, there is a fear that safety may be neglected, and thus there is a high possibility that a safety accident may occur in the elevating process of the lift.

In addition, in order to prevent safety accidents, a safety manager in charge of lift operation should be assigned.

Fourth, when driving the lift, more than twice the driving force is required compared to the elevator according to the present invention, the environment is polluted by the use of gear oil, and maintenance costs are high.

On the other hand, a method of elevating a small lift by installing a sheave on the upper part of the mast structure and installing a winch on the lower part, and winding a single wire rope on a wire drum, has also been proposed.

However, the conventional method described above, although vibration and noise can be reduced, cannot fundamentally solve the problems of the conventional lift of the rack and pinion method.
