Hereinafter, one embodiment of the ascending / descending link device and structure of the pawl of the present invention will be described with reference to FIG. 5 is a schematic diagram for explaining the up-down movement of the lifting apparatus.

Referring to the drawings, a lifting link device and structure of a pole of the present invention includes a main body 100, a link 200, a slide bar 210, a pivot 211, a slide hole 212, The roller unit 300 includes a roller link bar 310 and a roller 320. The roller unit 320 includes a transmission unit 400, 410, a wire 420, a wire fixing portion 430, a top fixing portion 440, and a pawl 500.

The main body 100 of the lifting device can move up and down according to the movement of the link part 200 which is constructed in a mechanically related relationship. The link unit 200 slides the roller unit 300 by a force transmitted from the transfer unit 400 so that the ascending / descending device can be easily moved up and down.

The wire 420 of the transmission unit 400 is connected to the main body 100 of the lifting and lowering apparatus or the power conversion apparatus 410 fixed to the slide bar 210 at the upper fixing unit 440 located at the upper end of the pole 500 And is coupled to the link portion 200 via a link. In this way, the operator can arbitrarily move up and down by using the wire 420 supporting or supporting the lifting / lowering device in the fixed upper fixing part 440.

On the other hand, the lifting device located on the pawl 500 receives the upward force of the wire 420 by the weight of the lifting device, and the wire 420 whose direction is changed through the power converter 410 The rotation link bar 220 is pulled.

A ring-shaped wire fixing portion 430 is coupled to both ends of the rotation link bar 220 so that the force of the wire 420 can transmit a force to one end of the rotation link bar 220. And also allows the wire fixing portion 430 and the rotary link bar 220 to rotate through a ring-shaped connection.

The rotation link bar 220 tries to rotate in a clockwise direction by the force transmitted from the wire 420 and rotates at one end of a plurality of auxiliary link bars 230 coupled to the pivot 221 at both ends of the rotation link bar 220 We also try to rotate clockwise together.

One end of the auxiliary link bar 230 connected to both ends of the rotation link bar 220 is spaced apart from and overlapped with the rotation of the rotation link bar 220 in the clockwise direction, The other end of the bar 230 pulls the roller rotation bar 240 inwardly, thereby causing it to slide inward.

The roller portion link bar 310 is also urged together by the roller rotation bar 240 that slides inwardly and the roller portion 300 coupled to the roller portion link bar 310 is pressed against the surface of the pawl 500 Respectively.

At this time, the rollers 320, which receive the force applied by the weight of the lifting and lowering device on both sides of the pawl 500, generate a braking force and fix the lifting and lowering device so as not to fall off.

The lifting device placed on the pawl 500 is subjected to a force to be lifted or lowered by the force of the worker or the machine and the wire 420 that has been changed in direction through the power converting device 410 pulls the rotating link bar 220 do.

One end of the auxiliary link bar 230 connected to both ends of the rotation link bar 220 may be spaced apart from each other due to the clockwise rotation of the rotation link bar 220, The other end of the link bar 230 slides inward by pulling the roller rotation rods 240 inwardly, thereby reducing the gap between the roller portions 300 located on both sides of the pawl 500.

The distance between the rollers 300 in the pawl 500 having a circumferential narrowing tendency is decreased together with the distance between the rollers 300, thereby allowing the roller 320 to continuously contact the outer surface of the pawl 500. Thereby allowing the roller 320 to balance and guide the lifting and lowering device so that the roller 320 is always in contact regardless of the size of the variable circumference of the pawl 500. [

When the wire 420 is subjected to a downward force by the force of the worker or the machine, the lifting device positioned on the pawl 500 is rotated in a direction opposite to the direction in which the rotating link bar 220, which has been pulled by the wire 420, Directional force. At the same time, the roller 320 is pressed against the outer surface of the pawl 500 to lose the braking force, and the lifting / lowering device can be lowered.

As the circumference of the pawl 500 gradually increases when the up-down device is lowered, the rotation link bar 220 is rotated counterclockwise, and one end of the auxiliary link bar 230, The roller rotation bar 240 is pushed out in accordance with the counterclockwise rotation of the bar 220 so as to slide outward.

As the roller rotation bar 240 slides outwardly, the distance between the rollers 320 located on both sides of the pawl 500 is widened, and the lifting device can move up and down irrespective of the variable circumferential size.
