The guide member 40 is rotatably provided at both sides of the rear end of the upper protective cover 23 of the driving part 26, and the front guide rollers 41 and 42 guided to the front of the hoistway structure 20 and 21. Wow; Side guide rollers 43 and 44 rotatably provided on the vertical fixing stand 25 and guided to both sides of the hoistway structure members 20 and 21; It is provided with a rotatable guide roller (45) and 46 (46) rotatably provided on the vertical fixing stand (25) and guided to the rear of the hoistway structure member (20) (21).

The Christogi device 50 is filled with grease therein, and the grease container (51) mounted on the upper port (28); A grease pump 53 connected to the grease storage tube 51 and operated as a control motor 52 to discharge grease to the outside; The grease pump 53 and the high pressure hose 54 are connected to the rack 38, the pinion 36 and the front guide rollers 41 and 42, the side guide rollers 43 and 44 and the rear guide rollers 45 and 46. A distributor 56 provided with a distribution port 55 for dispensing with; Connected to the distribution port 55 of the dispenser 56, a plurality of racks 38, pinion 36 and a plurality of greases for automatically injecting grease into the guide rollers (41, 42) (43, 44) (45, 46) The injection tube 58 is made of.

The grease storage tube 51 is screwed to the upper lid 60 made of a circular shape at the top, the upper coil spring 62 is fixed to the lower end of the upper lid 60, the moving plate 64 is connected to the lower When the grease is filled inside, the coil spring 62 is compressed to the upper portion, and the movable plate 64 is moved upward. When discharged to the outside, the coil spring 62 is gradually returned, and the movable plate 64 is lowered. Will be moved to.

At the outer circumference of the movable plate 64, a packing 64a for maintaining airtightness with the inside of the grease storage tube 51 is inserted. Then, the upper portion of the upper lid 60, the rotary knob 66 for releasing the fastening force of the upper lid 60 is detachably fastened.

In addition, a lower portion of the grease storage 51 is provided with an injection hole 51a for injecting grease from the outside, and a sensor 51b is provided at one side of the lower portion of the grease storage tube 51 to detect an exhausted state of grease. That is, when the moving plate 64 descends downward and approaches the sensor 51b, the moving plate 64 detects this, and transmits the signal to the control device, which is displayed as a lamp and a buzzer, so that the state of grease exhaustion can be known.

On the other hand, the grease storage container 51 constituting the Christo device 50 is provided with a control device 70, counting the number of lifting and lowering of the lifting device 10, the control motor for a predetermined time automatically when a predetermined number of times ( 52 is operated to supply and apply grease to the rack 38, pinion 36 and guide rollers 41, 42 (43, 44) (45, 46).

The operating state of the lifting device according to the present invention configured as described above will be described.

As shown in FIGS. 1 to 4, when the workers ride inside the transport port 28 constituting the lifting device 10, and then operate the lifting and lowering means 30, the driving motor 32 operates in a forward rotation. Then, the rotational force of the drive motor 32 is decelerated by the reducer 34, and the pinion 36 is rotated forward.

Accordingly, the pinion 36 engaged with the rack gear 38 between the circular hoistway structural members 20 and 21 constituting the lifting device 10 moves upward along the rack gear 38, thereby protecting the upper portion. The cover 23 and the carrier 28 are moved upward.

At the same time, the front guide rollers 41 and 42, the side guide rollers 43 and 44, and the rear guide rollers 45 and 46, which constitute the guide member 40, are circular lifting structure members 20 and 21. It moves upward along the outer circumferential surface of.

On the other hand, when the lifting device 10 rises and the workers complete the work, and then descends again, the workers ride inside the transport port 28, and when the drive motor 32 is reversely rotated, the pinion 36 reversely rotates. By moving downward along the rack gear 38, the upper protective cover 23 and the carrier 28 is to move downward.

As such, when the lifting device 10 moves up and down, the control device 70 provided in the grease storage box 51 counts the number of times the lifting device 10 moves up and down, the Christo device ( 50 is applied to automatically apply grease to the rack 38, pinion 36 and guide rollers (41, 42) (43, 44) (45, 46).

Referring to the operation of this, when the corresponding number of times of the control device 70 constituting the Christo device 50 as shown in Figure 5, the control motor 52 is operated for a predetermined time to grease storage 51 ) When the grease inside is discharged to the outside, the grease is discharged to the rack 38 and the pinion 36 and the guide roller through the injection pipe 58 provided in the high pressure hose 54 and the distribution port 55 of the distributor 56. Discharge is made to the (41, 42) (43, 44) (45, 46) area to guide the lifting and lowering of the lifting device (10).

On the other hand, in order to replenish the grease in the grease storage tube 51 is to be simply injected through the inlet (51a) of the lower portion of the grease storage cylinder (51).

At this time, a coil spring 62 is provided at an upper portion of the grease storage tube 51, and a moving plate 64 is connected to a lower end of the coil spring 62 so that grease is filled in the coil spring 62. When the moving plate 64 is compressed to move upward, and discharged to the outside, the compression spring 62 slowly returns and the moving plate 64 moves downward. As the moving plate 64 descends downward, the sensor When it approaches 51b, it detects this and transmits a signal to the control device to display the lamp and buzzer, so that the state of grease exhaustion can be known.

The grease application apparatus for a lift according to the present invention described above is not limited to the above embodiments, and has a general knowledge in the field of the present invention without departing from the gist of the present invention as claimed in the following claims.
