The present invention relates to a crane and a principle that can be used to control the height of the top crane arbitrarily as the structure is increased in the crane used in multi-purpose construction site.

Conventional climbing methods for cranes have been able to raise the position of the top cranes by stacking tower masts, and as a result have been devised only how the masts can be easily stacked.

Thus, when the top crane was no longer used, there was no way to remove the top crane other than reducing the height of the tower mast. At the construction site, the tower mast is used not only as a support for crane but also as a hardened product by installing a lift. As a conventional crane device, there is a need to assemble, disassemble and reassemble the mast. In this process, the existing tower mast adopting the rope lifting method should have a rope pulley attached to the uppermost mast, so the new mast must be inserted into the second from the top to increase the mast height. Reducing the height of the tower mast required the removal of the second mast from above, which required a lot of difficulty and complex attachments. On the other hand, in the climbing method by the hydraulic cylinder, the hydraulic unit was required separately, and the separate space as much as the stroke length of the cylinder was basically required.

The present invention allows the stacking and stacking of the masts sequentially and the top crane can be stored, moved and re-installed without disassembling the mast. Cage that can form a linear rack gear and vertically move up and down along the mast attaches a driving part to drive the pinion gear in the attached room so that the cage can be operated by the rack gear of the mast and the pinion gear of the cage. The cage can be moved up and down with the top crane mounted on the top of the cage.

In the present invention, when stacking masts and lifting cages, the top crane can be moved to the non-working position.When repairing or checking the top crane, the top crane is moved to the non-working position without disassembling the tower mast. In this state, the cage can be lowered to the ground level to repair the top crane, and during the initial assembly or after assembling, the trial run can be performed, thus reducing the inspection time until the crane can perform its full function. It is an object of the present invention to provide a climbing device which can be easily removed from the tower mast cage can be easily removed from the tower mast for other purposes than the crane specifically described with reference to the accompanying drawings The review is as follows.

Figure 1 shows an assembly perspective view of a crane equipped with a climbing device according to the present invention, the crane is equipped with a top crane 100 for carrying a variety of heavy goods, a crane that can be mounted and a drive unit that can be elevated along the tower mast The cage 200, which prevents the buckling of the tower mast, and the support 300 for supporting the tower mast, stacked from the base of the ground is stacked high and supported by the support to act as a center pillar for the cage can be elevated and top crane The tower mast 400, which also supports the support, can be largely divided into a base 500 that supports and maintains all the structures of the crane.

The top crane 100 is composed of a swing bed, a turntable, a rope, and a boom as a main device for towing a heavy object. Looking at the structure, the crane is placed on a swing bed 133 having a rectangular plate-like structure with rollers installed on both sides. The turntable 132 of the disc which can be rotated is installed and the frame 135 of the approximately c-shaped is bound on the turntable 132, and the base of the lower boom 128 is coupled with the hinge pin on the frame 135. Boom cable (3) holding the boom cable 121 that can adjust the boom angle (angle of the horizontal line by rotating the boom up and down) is attached, and the boom cable winch drum winding the boom cable 121 ( 118 and the hoist cable winch drum 116 wound around the hoist cable 115 are connected by a bracket and attached.

The boom is divided into a lower boom 128 and an upper boom 126 and is connected with two hinge pins 127 and fastening bolts, respectively. The up and down rotation of the boom is a boom fixed pulley that is hung on the end of the post 123 as the boom cable 121 wound around the boom cable winch drum 118 driven by the boom cable winch driving motor 119 is unwinded. 120) and the boom moving pulley 122 is closer and farther apart, one end is the boom moving pulley 122, the other is connected to the bracket 130 of the boom front end boom fixed cable 125 by the boom Adjust the rotation of the direction.

The hoist cable 125 wound around the hoist winch drum 116 driven by the hoist winch driving motor 117 passes through the hoist auxiliary pulley 114 and the hoist fixed pulley 113 to wind the hoist movable pulley 111 and the weight. It is fixed to the tip of the boom through the center of the 112 and wound around the hoist winch drum 116 by lifting and unloading the hoist moving pulley 111 with the hook hanging on the object.

The over-preventing device 131 which depends on the bracket 130 is to control the hoist cable 115 to stop immediately by a limit switch when the hoist moving pulley 111 rises and touches the weight 112. The crane working on the high floor has a lightning protection rod 129 for preventing lightning on the bracket 130 at the tip of the boom. This lightning rod is connected to the metal plate buried deep in the ground by the lightning rod and absorbs the high voltage current during discharge to prevent damage to the crane.

In order to elevate the top crane 100, the base 500 in FIG. 2 should be installed on a concrete floor of 1 m or more, and the concrete floor and the base 500 may be more integrated. In general, the anchor bolt 512 is buried in the floor to cure concrete, and then the base plate 511 is inserted into the anchor bolt 512 in accordance with the bolt hole 513 and the base plate 511 using a block or a washer. After adjusting so as to be horizontal, using a washer 514 and a nut 515 is fastened and fixed.

The mast is pre-laminated and assembled 2-3 pieces on the bape plate. The unit mast has four hollow pipe pillars 411 of the same length and is supported by four cross bars 412 at the upper, middle and lower ends. The upper and lower side rails are formed with a hole 420 in the vertical direction, and when stacked to be stacked, the upper and lower ends may be fixed by fastening means 417 such as bolts.

On one side of the crosspiece, a bolt hole 419 is drilled in the horizontal direction on the same vertical line, so that a rack 414 in which teeth of a gear are formed on each rod is fastened to the mast by a fastening means 418 like a bolt. Fix it.

In addition, a brace 413 is attached between the upper and lower rungs to prevent the mast from twisting or buckling. When stacking the mast 400, the protrusion 415 connected to the bottom of the other mast pillar is inserted into the hole 416 at the top of the pillar 411 to determine the position and fastening means such as bolts to the upper cross bar and the lower cross bar Fix it to (417).

In FIG. 3, in order to prevent buckling caused by self weight and top crane load when the mast is increased, the support 300 is connected to the mast crossbar 412 on the floor of each building, and the support 300 is each floor of the building. Balance the mast by adjusting the length of the support 300 with a stud bolt 316 fastened between the female threaded portion 315 attached to the bracket and the female threaded portion of the support pipe 311 attached to the bracket. give. The support pipe 311 on the mast side is fastened with a pin to the bracket 314 attached to the connecting plate 312.

The cage 200 is divided into a lower floor with an accessory room and an upper floor in which the top crane 100 is installed. The lower floor includes a bottom plate 217 and a plurality of pedestals 215 formed on the bottom plate 217 to form an upper floor. It supports the loading plate 214 and attaches the plate 218 to the pedestal 215 and attaches the main motor 219 to the plate 218 to serve as the main power source for driving the cage 200 and the main motor 219. After adjusting the rotation speed by attaching the reducer 221 to the axis of the two pinions 222 connected to the reducer 221 is moved over the rack 414 (see Fig. 6 and 7).

In order to keep the contact between the rack 414 and the two pinions 222 constant, a tension roller 223 fixed to an axis of the plate 218 is provided at an intermediate position between the two pinions 222.

When the main motor 219 is abnormal, the auxiliary motor 220 is installed at the bottom of the main motor 219 to prevent the fall of the cage 200, and the reducer 224 and pinion ( 225 is connected continuously and the tension roller 226 horizontally with the pinion 225 is formed so that the rack 414 and the pinion 225 of the auxiliary motor always maintain a constant contact surface.

The cage 200 has four guide rollers on the upper surface of the lower floor plate 217 and the lower surface of the upper loading plate 214, so that the cage 200 deviates when the cage 200 moves up and down on the mast pillar 411. To reduce the friction and allow the cage to rise and fall smoothly.

A set of guide rollers is composed of three rollers 228, 229 and 230, of which two holding rollers 228 and 229 are attached to a bracket 232 which can be rotated by a hinge pin 231. The other Laura 230 is fixedly connected to the bottom 214, 217 of the cage.

The cage 200 on which the top crane 100 is mounted is installed in the field or the work is completed and the cage 200 from the tower mast 400. When the two separate rollers are attached to the rotating bracket can be separated from the cage 200 from the tower mast 400.

When the mast is stacked on the base plate 511 and the cage is coupled, the cage is lifted up by the driving of the main motor to the top of the tower mast, and the center of the top crane 200 in the non-working position is centered on the top of the tower mast 400. Move to. This is the normal appearance of the crane to work. 8 and 9 are perspective views of the swing bed 133 in a working position and a non-working position. The swing bed 133 is installed on the frame 213 formed on the upper stacking plate 214 of the cage 200. The top crane 100 can move from the non-working position to the working position in the horizontal beam of the frame 213. The swing bed 133 moves forward and backward by rotation of the bearing housing 137 attached to the lead screw 138 coupled to the nut 139 attached to the bottom of the swing bed 133.

The linear movement of the swing bed 133 is made by the lead screw 138 and the nut 139 and the power is obtained from the moner 136. Moving rollers 134 attached to both sides of the swing bed 133 along the pipe rails 212 horizontally connected between the frames 213 of the stacking plate 214 of the top crane forming the upper layer of the cage 200. As the top crane 100 is rolled, the top crane 100 moves to the top center of the tower mast 400, and the top crane 100 can be easily moved with little power by the friction coefficient of the moving roller 134. When the tower mast 400 is stacked to the working height, the swing bed 133 is moved to be positioned at the center of the tower mast 400, and then the top hole of the pillar 411 of the mast 400 and the bottom 4 of the swing bed 133.
