The lift 400 includes the frame 410, the operation member 420, the auxiliary frame 440, the link member 430, the guide roller 450, the lifting roller 460, and the rotation lever 461. ), A return spring 470, and a braking means 420.

The frame 410 includes a pair of frame members positioned on the left and right sides of the pillar 100 and connecting rods 411 connecting the frame members to each other.

The actuating member 100 is like a lever for pressing down on a foot, and as shown in FIG. 5B, two hinge coupling parts 421 provided at both ends of one end are connected to each pair of frame members of the frame 410. The hinge is coupled, the foot hanger 422 for hooking the foot of the worker is coupled to the top of the other end.

The auxiliary frame 440 surrounds the pillar 100 above the operating member 420, and the auxiliary frame 100 has a circular rod-shaped guide roller 450 and the pillar 100 in close contact with the front surface of the pillar 100. The lifting roller 460 in the form of a circular rod that is in close contact with the back of the shaft is coupled. The pillar 100 is pinched between the guide roller 450 and the lifting roller 460 and the auxiliary frame 440 is inclined toward the front of the pillar 100. One end of the shaft of the lifting roller 460 is coupled to the rotary lever 461, the operator can rotate the lifting roller 460 by holding and rotating the rotary lever 461.

The link member 430 is hinged to the operation member 420 and the auxiliary frame 440 and is located in front of the pillar 100. The return spring 470 has one end coupled to the auxiliary frame 440 and the other end coupled to the shaft for connecting the link member 430 and the operation member 420.

The braking means 480 is installed below the lift 400. The braking frame 481 is spaced apart from the auxiliary frame 440 and surrounds the column 100. The braking frame 481 includes a brake member 483 in the form of a square rod in close contact with the rear surface of the column 100. A guide rod 484 in the form of a circular rod that is in close contact with the front surface of the pillar 100 is axially coupled. The pillar 100 is pinched between the brake member 483 and the guide roller 484 and the braking frame 481 is inclined forward of the pillar 100. A handle 482 is coupled to one end of the shaft of the brake member 483 so that the operator grasps the handle 482 and pushes it toward the rear of the pillar 100 to release close contact between the brake member 483 and the rear surface of the pillar 100. . The lower end of the braking spring 485 is coupled to the shaft coupled to the frame 410 and the other end of the braking spring 485 is coupled to the braking frame 481 and positioned in front of the pillar 100.

The operation of the lift 400 will be described with reference to FIGS. 5A to 5C as follows.

The braking frame 481 of the braking means 480 is inclined toward the front of the column 100 and the braking spring 485 is pulled downwards in front of the braking frame 481 so as to be inclined in front of the braking frame 481. Since the brake member 483 has a rectangular corner, the corners of the brake member 483 are pressed against the rubber plate 101 on the back side of the column. Since this is very high, the lift 400 will maintain its height without slipping downward relative to the column 100. However, when the operation member 420 rises by stepping on the lift 400, the direction is reversed, and the brake member 483 has the rubber plate 101 at the rear of the pillar 100 because the pulling force of the brake spring 485 is not applied. It is possible for the lift 400 to be lifted because the force for pressing) is weakened.

When the foot 422 of the operation member 420 is raised as shown in FIG. 5A, the operator puts the foot into the footrest 422 and steps on the operation member 420, as shown in FIG. 5B. Is raised relative to the pillar (100). When stepping on the operating member 420, the linking portion of the return spring 470 of the link member 430 is lowered at this time, the return spring 470 is a link member due to the nature of maintaining a constant length of the return spring 470 The coupling portion of the return spring 470 of the link member 430 is pulled down by pulling the engagement portion of the return spring 470 of the link member 430, so that the engagement with the return spring 470 of the link member 430 is reduced. Instead of the lowered portion, the hinge coupler 421 of the operating member 420 is raised, thereby raising the frame 410 of the lift 400 coupled with the hinge coupler 421 of the operating member 420. do. When stepping on the actuating member 420 and then the pressing force is removed, the actuating member 420 is returned to the state before being stepped by the return spring 470. The worker raises the lift 410 by repeating the stepping on the operation member 420.

On the other hand, when lowering the lift 400, the operator grasps the handle 482 of the braking means 480 with one hand and pushes it back to the pillar 100 so that the brake member 483 is placed on the rubber plate 101 at the rear of the pillar 100. After releasing the pressing force, the other hand lowers the lift 400 by holding the rotation lever 461 of the lift 400 and rotating the lifting roller 460. The lifting roller 460 has a rough surface and is in close contact with the rubber plate 101 provided on the back of the pillar 100 so that a lot of frictional force is applied, thereby rotating the lifting roller 460 to lift the lift 400 to the pillar 100. I can move it.

The installation order of the lift aerial work piece according to the present invention is first fixed to the outer wall of the support (120) building and then fixed to each support 120, the column (100) is installed with the lift 400 is coupled with the lift 400 It is the same as placing the working scaffold 300 on the scaffold pedestal 200 is fixed with a chain (310). Raising or lowering of the lift 400 may be performed by a worker standing on the work footing 300 and stepping on the operation member 420 or rotating the lifting roller 460, wherein the height of any one lift 400 is raised. Since only a sudden change may cause the working scaffold 300 to be inclined severely, it is preferable that a plurality of workers simultaneously operate the lifts 400 coupled to each of the scaffold pedestals 200 on both sides of the working scaffold 300.
