In addition, when the piston of the lifting driving unit 30 is lowered, the lifting plate 20 is lowered, thereby lowering the transfer object 2 to a lower level.

Accordingly, the lifting plate 20 may be raised or lowered through the lifting driving unit 30 to place the transfer object 2 at a desired position.

Then, after placing the object to be transferred 2 in a desired position, the object to be transferred 2 may be constructed according to the purpose.

For example, when the object to be transferred 2 is applied as a tray for electric wires, it may be installed on the ceiling.

And, when the transfer object 2 is applied as a brick, it is sufficient to form a wall by stacking it up to a certain height.

The forward/backward driving unit 40 is configured to position the withdrawing/input unit 50 on the upper side of the moving body unit 10 or to protrude the withdrawing/output unit 50 on the moving body unit 10 .

Next, the foreign matter removing means 110 applied to the lift according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4 .

3 is a front view showing a foreign material removing means applied to a lift according to an embodiment of the present invention, and FIG. 4 is a plan view showing a foreign material removing means applied to a lift according to an embodiment of the present invention.

The foreign matter removal means 110 is provided to remove foreign matter such as dust from the transfer object 2 to be loaded on the lifting plate 20 .

To this end, the foreign matter removing means 110 includes the installation plate 111, the accommodation box 112, the elastic support part 113, the fixing block 114, the holder part 115, the solenoid 116 and , At least any one or more of the collision plate 117 and the discharge fan 118 may be included.

At this time, the foreign matter removing unit 110 may remove foreign matter from the object to be transferred 2 having a certain length, such as a cable tray or a pipe, rather than bricks.

The installation plate 111 is coupled to one side of the moving body 10 .

Additional rollers 111a that roll along the ground along with the above-described rollers 10a are installed at each corner of the lower surface of the installation plate 111.

The additional roller 111a may be axially coupled to the mounting plate 111 and rotated in place so as to be able to move in a straight line and change direction.

The receiving box 112 is coupled to the upper surface of the installation plate 111.

The upper surface of the accommodating box 112 is opened so that the transfer object 2 can be taken in and out.

An accommodation space in which the transfer object 2 is accommodated is formed inside the accommodation box 112 .

An upper surface of the accommodating box 112 may be opened and closed by a cover 1121 .

A discharge port 1121a is formed in the cover 1121 to discharge foreign substances taken in by the discharge fan 118 to be described later to the outside.

The elastic support part 113 is installed on the bottom surface of the accommodation space of the accommodation box 112.

The elastic support part 113 may be applied as a leaf spring or coil spring, and the drawing shows an example applied as a leaf spring formed in a 'C' cross-sectional shape.

The fixing block 114 is coupled to the upper surface of the elastic support part 113. Due to this, the fixing block 114 is elastically supported by the elastic support part 113 .

The fixing block 114 has fixing grooves 114a on both sides of which one side of the objects 2 to be transferred are fixed along the longitudinal direction.

Therefore, a plurality of transfer objects 2 are fixed to one side and the other side of the fixing block 114, respectively.

On both sides of the upper surface of the fixing block 114, a plurality of spiral holes 114b are formed at regular intervals.

The spiral hole 114b is formed at a position corresponding 1:1 to the object to be transferred 2 located in the fixing groove 114a.

The holder part 115 may be formed of bolts.

The holder part 115 is fastened to the spiral hole 114b of the fixing block 114, and presses and fixes the upper surface of the object to be transferred 2, the lower end of which is located in the fixing groove 114a.

The solenoid 116 is installed on the ceiling surface (lower surface of the cover 1121) of the housing box 112.

The solenoid 116 strikes the upper surface of the fixing block 114 at predetermined time intervals.

When the solenoid 116 strikes the fixing block 114, the elastic support 113 repeats compression and expansion, and as a result, vibration occurs in the transfer object 2 fixed to the fixing block 114.

Therefore, the foreign matter attached to the object to be transferred 2 is brushed off.

The collision plate 117 is installed on both inner side walls of the housing box 112, respectively.

The collision plate 117 includes a flange 1171 fixed to the inner wall of the housing box 112.

The collision plate 117 is installed to the flange 1171 with a downward slope.

The collision plate 117 may be formed of a material having elasticity such as metal.

A rubber cover 1172 on which the object to be transferred 2 collides is placed on the collision plate 117 .

The rubber cover 1172 protects the object to be transferred 2 from collision.

The object to be transferred 2 collides with the rubber cover 1172 when the solenoid 116 descends due to hitting the fixing block 114 . Accordingly, vibration is generated in the object to be transferred 2 due to collision with the rubber cover 1172 . Due to this, the foreign matter attached to the object to be transferred 2 is brushed off.

That is, when the solenoid 116 strikes the fixing block 114, the elastic support 113 repeatedly contracts and expands, so that the object to be transferred 2 is repeatedly lowered and raised. Vibration is continuously generated in ), and when the object to be transferred (2) descends, it collides with the rubber cover (1172), so vibration is additionally generated in the object (2) to be transferred, and is buried on the surface of the object (2) to be transferred. It can effectively remove foreign matter.

At this time, the solenoid 116 may be programmed to rise after the plunger strikes the fixing block 114 once, and then operate again when the elastic support 113 stops contracting and expanding.

For example, when the elastic support 113 is hit once by the plunger of the solenoid 116 and contracted and expanded for about 10 seconds and then restored to its original state, the solenoid 116 operates at 10 second intervals to fix the fixing block 114. that can be hit.

Also, operation and stop of the solenoid 116 may be controlled by an operator.

To this end, an operation button (not shown) for operating the solenoid 116 and a stop button (not shown) for stopping the operation of the solenoid 116 may be provided in the accommodating box 112, respectively.

In addition, the operation of the solenoid 116 may be controlled by a known remote control method.

On the other hand, the discharge fan 118 is installed on the bottom surface of the cover 1121, and is disposed below the discharge port (1121a).

Accordingly, the discharge fan 118 operates together with the solenoid 116 to suck foreign substances separated from the transfer object 2 and discharge them to the outside of the accommodation box 112 .

At this time, the foreign matter accumulated on the bottom surface of the receiving box 112 can be removed with a suction device such as a vacuum cleaner after separating the transfer object 2 from the fixing block 114 later.

Then, by turning the transfer object 2 upside down at 180 degrees and fixing it to the fixing block 114, foreign substances may be removed even from the bottom portion of the transfer target object 2.

In this way, if the foreign matter is removed from the object to be transferred 2 through the foreign matter removing means 110, it prevents workers from inhaling foreign substances such as dust in the process of constructing the object to be transferred 2 according to the purpose, thereby improving health. It can protect and prevent foreign substances from getting into work clothes or entering the eyes.

In addition, the foreign matter removing means 110 is coupled to the moving body 10 and moves together, and the lift 1 according to an embodiment of the present invention has a lifting plate 20, a pull-out unit 50 and , The object to be transferred 2 can be stored in the additional lifting plate 90 and the fixing block 114, respectively, so that a large amount of the object 2 can be transferred at one time.

Those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts thereof are included in the scope of the present invention. should be interpreted
