Description

Fixing apparatus of traction machine-room-ress elevator}

The present invention relates to a hoisting device for a lower drive type elevator that does not require a machine room. More specifically, the lower side wall of the hoistway in which the elevator is installed and operated can be easily installed without a separate machine room, and also vibrates according to the hoisting drive. It relates to a hoisting device of a lower drive type elevator to be firmly fixed without being separated.

In general, an elevator is a device for elevating passengers or cargo in a hoistway formed in the up and down direction of a building, and most of them are connected to the hoist platform, which is arranged so that the hoist is carried out within the hoistway, and the hoist platform is connected to the hoist platform by a wire rope. Rope-type elevators having a balance weight and a hoist that lifts and drives the platform and the balance weight by frictionally contacting with the wire rope on the upper side of the hoistway are used widely.

However, most of the above-mentioned rope type elevators have a separate installation space called a machine room at the upper part of the hoistway so as to install the hoisting machine, the control panel, and the like, thereby increasing the large occupied space according to the installation of the elevator. The problem of impairing the service capability of the party was brought about.

Accordingly, in recent years, in order to increase service capacity per unit space occupied by elevators, installation of so-called machine roomless elevators excluding machine rooms is gradually increasing.

The hoisting machine 1 of the lower drive type elevator used in such a machine roomless elevator is a gearless type synchronous motor, which is quite small in size without deterioration as a hoisting machine, and most of the hoistway 100 is shown in FIG. 4. The wire rope fixedly wound to the lower side of the elevating medium through the sieve of the upper end of the balance weight 110, the other side is used to be connected to the suspension sheave side coupled to the platform 120.

In other words, the fixing of the hoisting machine 200, first fixing the fixing panel 300 to the inner surface of the hoistway 100 using a general anchor bolt, and then the body frame of the hoisting machine 200 with the fixing panel ( 210) using the fixing brackets 212 mounted on the upper and lower parts using a general screw or the like was mainly used.

However, in the conventional hoisting system, the vibration of the hoisting machine causes a lot of vibrations caused by the driving of the hoisting machine as it is driven by a large power to lift or lift passengers or cargoes. Cracks are generated due to the vibration on the side of the hoistway, which causes the anchor bolt to have fluidity, and the fixed panel also flows, causing a problem in that the hoisting machine is not smoothly driven.

In addition, as the anchor bolts have fluidity as described above, the anchor bolts are eventually separated and the fixed panel itself fixed with the hoisting machine is separated from the side of the hoistway, which also includes a risk that a large accident may occur.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose of which is an easy installation without a separate machine room to the lower side wall of the hoistway in which the elevator is installed and operated, as well as deviating from the vibration caused by the hoist drive To be firmly fixed without

Another object of the present invention is to make a more tight coupling fixed when the winding machine body frame is coupled to the upper, lower dust-proof part.

In the hoisting machine fixing device of the elevator, which is installed to the lower side of the hoistway, the hoisting machine 200 generating a driving force to lift the hoisting platform as shown,

The present invention is a well-known anchor channel 12 that is embedded to be welded fixed to the base rebar and the like during the construction of the hoistway in the horizontal direction of the lower side of the hoistway and a plurality of common hook head bolts mounted on the anchor channel sliding 14 Mounting fixing portion (10) consisting of;

A plurality of fastening holes 22 formed on one surface thereof, and a mounting frame 20 having a rectangular frame shape made of a known H beam fixed by the hook head bolt and the nut;

Both ends of the upper and lower frames (20A, 20B) of the mounting frame and the anti-vibration frame (34) in which the anti-rubber (32) is built into the bottom and the upper surface of each of the connecting brackets (36) of the general fixed method bolts or Each of the upper and lower dustproof parts 30 and 30a fixedly coupled through welding and mounted by bolts and nuts;

The dustproof frame is coupled to the inside of the mounting frame by a bolt or welding, which is a general fixing method, by the fixing brackets 212 mounted on the upper and lower body frames 210 of the hoist 200.

When the lower dustproof part 30a is formed with a gearless type synchronous motor in the lower part of the main body frame according to the structure of the hoisting machine, it is not installed as one part in the transverse direction like the upper prevention part, but a pair of It is preferable that the dustproof frame 34 is fixed between bolts or welding between the connection brackets 36 and formed on both sides.

In addition, the fixing bracket 212 mounted to the body frame 210 of the hoisting machine 200 which is fixed to the dustproof frame 34 has a fitting groove 212a formed therein so that the dustproof frame 34 is welded and coupled. By fixing, more tight coupling can be achieved.

The present invention configured as described above, first, using a plurality of hook head bolts are inserted into the anchor channel is inserted into the lower side of the hoistway of the mounting fixing fixing the mounting frame formed with a plurality of fastening holes in one surface with a nut.

At this time, the mounting frame is fixed to the upper and lower dust-proof frame of the dust-proof part using a fixed bracket mounted on the upper and lower body frame of the hoisting machine, and using the connecting brackets fixed to both ends of the dust-proof frame, The lower frame may be fixed, and the upper and lower dustproof parts and the hoisting machine may be fixed with the main body frame first, and then the main frame may be fitted with fixing fixing parts of the hoistway.

Therefore, the installation of the lower drive type hoist is a simple fixing operation of the worker, that is, the mounting frame is mounted on the lower side of the hoistway by bolting method by the mounting fixing part, and the mounting of the hoisting machine is also mounted on the lower part of the hoistway. Like the dustproof part, it is possible to fix simply and firmly through fixing by bolting method.

As such, when the mounting of the hoist is completed, the wire rope wound with the hoist is connected to the balance weight, and the other side of the hoist of the hoistway, and the other side is connected to the suspension sheave coupled to the hoist, thereby driving the hoist.

Accordingly, the vibration generated by driving the hoist is absorbed by the anti-vibration rubber formed inside the anti-vibration frame of the upper and lower dustproof parts installed between the mounting frame and the main frame of the hoist, and the vibration is mounted to the lower side of the hoistway. It will not be delivered to the mounting frame.

Therefore, since the vibration caused by the hoisting drive is not transmitted to the mounting frame mounted to the side of the hoistway, the hoisting drive is also made more stable to have a safe driving condition.
