The guide rail may be horizontally coupled to the attachment plate 100 while being positioned to be positioned between the upper portion of the attachment plate 100, that is, the support member. The slider may be reciprocated along the guide rail.

At this time, the rack gear 320 is coupled to the slider along the longitudinal direction.

The rack gear 320 is a part in which gears are formed at equal intervals on one surface of a horizontal plate or beam. Thus, the rack gear 320 may be reciprocated together with the slider.

The steering cylinder 330 is horizontally coupled to the side of the attachment plate 100 on one side of the LM guide 310.

The body of the steering cylinder 330 is located opposite to the LM guide 310, the rod is coupled to the rack gear 320.

Therefore, as the rod of the steering cylinder 330 moves forward and backward, the slider and the rack gear 320 reciprocate horizontally along the guide rail.

Since the lifting fixed arm 410 must support the weight, it may be made of a material having sufficient strength and rigidity.

And the lifting pivot arm 420 is rotatably coupled to the end of the lifting fixed arm 410.

In addition, the lifting cylinder 430 is mounted between the steering plate 360 and the lifting pivot arm 420.

The body of the lifting cylinder 430 is rotatably coupled to the lifting pivot arm 420, and the rod is rotatably coupled to the lower surface of the steering plate 360.

That is, the lifting fixed arm 410, the lifting pivot arm 420, the lifting cylinder 430 is coupled to form a triangle with each other.

Accordingly, when the rod of the lifting cylinder 430 moves forward, the angle formed by the lifting fixed arm 410 and the lifting pivot arm 420 increases while the rod moves backward. .

As will be described later, the driving part 500 is coupled to the lifting pivot arm 420.

Next, the driving unit will be described with reference to FIG. 5. FIG. 5 is a side view illustrating a structure of a driving unit of the present invention shown in FIG. 2.

The gear box 510 is a case for accommodating the driving sprocket 530, the driven sprocket 540, and the driving gear 570, and an accommodation space is formed therein as shown.

The gear box 510 may be coupled to one side of the lifting pivot arm 420 of the lifting unit 400 to be rotated together with the lifting pivot arm 420.

The driving motor 520 is installed on one side of the gear box 510.

For example, as shown in Figure 5 may be installed on the upper side of the gear box 510, or as shown in Figures 8 to 10 may be installed on the lower side of the gear box 510.

For reference, the drive motor 520 may be equipped with a separate motor bracket to the gear box 510 and install the drive motor 520.

The drive sprocket 530 is coupled to the shaft of the drive motor 520 to rotate.

The driven sprocket 540 is rotatably accommodated and installed inside the gearbox. At this time, the drive sprocket 530 and the driven sprocket 540 is wound around the chain and the driving force of the drive motor 520 is transmitted to the driven sprocket 540.

The driving gear 560 is coupled to the driven sprocket 540 and rotates together.

The drive gear 560 is also installed to be accommodated in the gearbox and is installed with the same shaft as the driven sprocket 540.

The driving gear 570 is interlocked with the driving gear 560.

The driving gear 570 may also be installed to be accommodated in the gear box 510.

The driving wheel 580 is coupled to the gear shaft of the driving gear 570.

The traveling wheel 580 is a wheel provided outside the gear box 510 and in contact with the ground.

Accordingly, the rotation driving force provided by the driving motor 520 is passed through the driven sprocket 540, the chain 550, the driving sprocket 530, the driving gear 560, and the driving gear 570. The lifter rolls as the traveling wheel 580 rotates.

Hereinafter will be described the operation of the present invention.

First, the attachment plate 100 is attached to the side of the structure or the workpiece, usually four can be attached to each corner of the slope.

As described above, the attachment plate 100 may be closely adhered to the side of the structure, and the edge may be welded and fixed to the edge.

At this time, the driving wheel 580 is placed on the floor.

Next, when the elevating cylinder 430 of the elevating unit 400 is operated, the rod is advanced, and thus the attachment plate 100 is lifted while the elevating pivoting arm 420 is opened.

The traveling wheel 580 is supported by the ground and lifts the structure to which the attachment plate 100 and the attachment plate 100 are attached by reaction force.

At this time, increase about 110 ~ 115mm.

Since a very large load is applied to the lifter, the center of gravity of the driving wheel 580 and the lifter should be matched as much as possible.

When the driving motor 520 of the driving part 500 is driven in the lifted state, the driving wheel 580 is driven to rotate so that the structure moves slowly.

If the direction is to be changed, the steering cylinder 330 may be operated. The steering gear 350 and the steering plate 360 rotate forward or reverse according to the forward and backward movement of the rod of the steering cylinder 330. Done.

When the steering plate 360 rotates, both the lifting unit 400 and the driving unit 500 coupled to the steering plate 360 rotate forward or reverse, and eventually, the driving wheel of the driving unit 500. Since 580 is rotated, the direction can be switched.

When the movement is completed, when the lifting cylinder 430 is reversed to rotate in the direction in which the lifting pivot arm 420 is folded, the attachment plate 100 and the structure are slowly lowered and the ground is seated.

The attachment plate 100 attached by welding may be removed by melting again by welding.

Hereinafter, another embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. 6 is a perspective view illustrating a large steerable structure attachable lifter according to another embodiment of the present invention, and FIG. 7 is a side view of the present invention shown in FIG. 6.

Another embodiment of the present invention is a structure that allows the operator to manually change the direction by changing the structure of the steering unit 300, the semi-automatic steering by allowing the direction to be changed by the force of the hydraulic pressure.

To this end, the steering unit 300 is an LM guide 310, rack gear 320, steering cylinder 330, steering shaft 340, steering gear 350, steering plate 360, manual handle 370 , The hydraulic control valve 380, the valve shaft 381, the valve opening and closing gear 390 may be configured.

The LM guide 310 is installed horizontally on the upper portion of the attachment plate 100, the LM guide 310 includes a guide rail that is horizontally installed and a slider that is linearly reciprocated to be seated on the guide rail. .

The LM guide 310 may be horizontally coupled to the attachment plate 100 while being disposed to be positioned between the upper portion of the attachment plate 100, that is, the support member.

At this time, the rack gear 320 is coupled to the slider along the longitudinal direction. Thus, the rack gear 320 may be reciprocated together with the slider.

The steering cylinder 330 is horizontally coupled to the upper portion of the LM guide 310.

Here, the steering cylinder 330 preferably uses a bidirectional cylinder or a double-acting cylinder, and both rods of the steering cylinder 330 are coupled to the rack gear 320, respectively.

Therefore, as the rod of the steering cylinder 330 is driven left and right, the rack gear 320 reciprocates horizontally.

The steering shaft 340 is supported and rotatably coupled while passing through the mounting hole 211 of the mounting plate 210, and the internal structure is substantially the same as described above.

And the steering gear 350 is coupled to the end of the steering shaft 340. In addition, the steering gear 350 may be horizontally interlocked with the rack gear 320 so that the steering gear 350 may rotate forward or reverse according to the reciprocating movement of the rack gear 320.

A steering plate 360 coupled to the lower end of the steering shaft 340 is provided below the steering gear 350.

Therefore, since the steering shaft 340 also rotates forward and backward according to the forward and reverse rotation of the steering gear 350, the steering plate 360 coupled to the steering shaft may be driven to rotate.

On the other hand, the manual handle is attached to the upper surface of the lifting fixed arm 410 coupled to the steering plate 360.

As a configuration for manually rotating the lifting fixed arm 410 by holding the manual handle 370 by a worker and applying torque, the manual steering wheel 370 may be hinged to the lifting fixed arm 410 to be rotatable.

And the hydraulic control valve 380 is installed on the upper surface of the mounting plate 210 of the support frame 200.

The hydraulic control valve 380 opens and closes the hydraulic pressure to selectively supply hydraulic pressure to the steering cylinder 330. That is, since the steering cylinder 330 is a bidirectional cylinder, when the hydraulic pressure is supplied to the left side, the rod is driven to the right side, and the rack gear 320 is moved to the right side. When the hydraulic pressure is supplied to the right side, the rod is driven to the left side, the rack The gear 320 moves to the left.

The valve shaft 381 is rotatably embedded in the hydraulic control valve 380. The valve shaft 381 protrudes outward and extends to the side of the steering gear 350.

The valve opening and closing gear 390 is coupled to the valve shaft 381 to rotate, and the valve opening and closing gear 390 is linked to the steering gear 350.

Looking at the operation of the steering unit 300 made of such a structure, when the operator grabs the manual handle 370 and rotates the lifting fixed arm 410 in a desired direction, the lifting fixed arm 410 is combined The steering plate 360 rotates in the same direction.

When the steering plate 360 rotates, the steering gear 350 rotates together, and the valve opening / closing gear 390 linked to the steering gear 350 rotates.

When the valve opening and closing gear 390 rotates, the valve shaft 381 coupled to the valve opening and closing gear 390 rotates so that the hydraulic control valve 380 opens in one direction.

When the hydraulic control valve 380 is opened, the hydraulic pressure starts to be supplied to one side of the steering cylinder 330, and when the other rod of the steering cylinder 330 is driven, the rack gear 320 coupled to the other rod is moved. The steering gear 350 linked by the movement of the rack gear 320 is rotated in the same direction. That is, the steering gear 350 manually rotated by the operator may eventually increase the rotational force due to the operation of the rack gear 320 so that the operator may easily turn the manual handle 370.

As a result, when the operator turns the manual handle 370 in a direction to change direction, power is initially applied, but the hydraulic control valve 380 is opened to supply hydraulic pressure so that the steering cylinder 330 operates. By doing so, the steering gear 350 is rotated by the hydraulic pressure, the operator can easily change the direction.

Another embodiment of the present invention will be described with reference to FIGS. 8 to 10. FIG. 8 is a perspective view illustrating a steerable structure-attached lifter according to another embodiment of the present invention, FIG. 9 is a side view of the present invention shown in FIG. 8, and FIG. 10 is a view of the present invention shown in FIG. 8. The other side view is shown.

Another embodiment of the present invention is to change the structure of the steering unit 300 shown in Figures 6 and 7, differently, LM guide 310, rack gear 320, steering cylinder 330, connecting member 331 ), Steering shaft 340, steering driven gear 352 and steering drive gear 351, steering plate 360, manual handle 370, hydraulic control valve 380, valve shaft 381, valve opening and closing gear 390.

Since the LM guide 310 and the rack gear 320 are substantially the same as the structure described above, a detailed description thereof will be omitted.

A steering cylinder 330 of a bidirectional cylinder or a double acting cylinder type is horizontally installed on the LM guide 310.

The rods on both sides of the steering cylinder 330 are coupled to the rack gear 320 by a connecting member 331. That is, one end of the connection member 331 is coupled to the rod and the other end is coupled to one end of the rack gear.

Therefore, as the rod of the steering cylinder 330 is driven left and right, the rack gear 320 reciprocates horizontally.

The steering shaft 340 is supported and rotatably coupled while passing through the mounting hole 211 of the mounting plate 210, and the internal structure is substantially the same as described above.

However, the steering driven gear 352 is coupled to the lower end of the steering shaft 340, and the steering drive gear 351 is coupled to the upper end. Specifically, the steering drive gear 351 is located on the upper side of the mounting plate 210, the steering driven gear 352 is located on the lower side.

At this time, the steering driven gear 352 is horizontally interlocked with the rack gear 320 so that the rack gear 320 can be reciprocated left or right by forward or reverse rotation of the steering driven gear.

The steering plate 360 is coupled to the lower side of the steering driven gear 350 to rotate together.

On the other hand, unlike the above, the manual handle 370 may be coupled to the upper end of the steering shaft 340. In other words, it may be positioned above the mounting plate 210.

Therefore, as a configuration for manually rotating the steering shaft 340 by holding the manual handle 370 by a worker and applying torque, a handle is provided.

And the hydraulic control valve 380 is installed on the upper surface of the mounting plate 210.

A valve shaft 381 is rotatably embedded in the hydraulic control valve 380, and a valve opening and closing gear 390 is coupled to the valve shaft 381 to rotate. At this time, the valve opening and closing gear 390 is linked to the steering drive gear 351.

One or more valve opening / closing gears 390 are provided to increase speed by using a smaller gear than the steering drive gear 351. That is, even if a small torque is input to the steering drive gear 351, the output can be output with a large torque so that the operator can easily open and close the hydraulic control valve 380.

Looking at the operation of the steering unit 300 having such a structure, when the operator grabs the manual handle 370 and rotates the steering shaft 340 in the desired direction, the steering drive gear coupled to the steering shaft 340 351, the steering driven gear 352 and the steering plate 360 rotate in the same direction.

At this time, when the steering drive gear 351 rotates, the interlocking valve opening and closing gear 390 rotates, thereby opening the hydraulic control valve 380 in one direction.

When the hydraulic control valve 380 is opened, the hydraulic pressure starts to be supplied to one side of the steering cylinder 330, and when the other rod of the steering cylinder 330 is driven, the rack gear 320 coupled to the other rod is moved. The steering driven gear 352 linked by the movement of the rack gear 320 is rotated in the same direction.

That is, the steering drive gear 351, which the worker rotates manually, eventually increases the rotational force due to the operation of the rack gear 320 so that the operator can easily turn the manual handle 370, and the lifting unit ( The rotation is easily performed by rotating the 400 and the driving part 500.

For reference, an emergency handling means 411 may be further provided on the upper surface of the lifting fixed arm 410. The emergency handling means 411 has a failure or problem in hydraulic driving by the manual handle 370. When generated, a separate tool is used to provide a space for applying torque to the lifting fixed arm 410.

For example, it is a structure that the operator can apply a force by inserting a beam or rod into the emergency handling means (411).
