Abstract

The present invention performs lifting operation, neutral operation, and descending operation of a user placed on a foot hold of a lower side of a power transmission moving frame connected to a winch generating the mechanical power which is not the users own power in a ladder by using mechanical power. According to the present invention, a winch frame comprises: a roller fixing plate; the moving frame; and the winches.

Description

Fully automatic ladder {omitted}

The automatic ladder according to the present invention is characterized in that a ladder user moves a ladder up and down by attaching a winch frame to one side of a folding type A type ladder, The frame is attached to the bottom of the frame. The frame is attached to the winch. The end of the winch is connected to the winch on the bottom. The winch motor operates to move the frame and the footboard up and down. To change the location of

Hereinafter, a fully automatic ladder according to the present invention will be described in detail with reference to the accompanying drawings.

The integrated automatic ladder of assembly is a bolt for connecting the first side of the folding type A type ladder and the second side of the folding type A type ladder by the nut 5. The bottom side can be widened and the lower side can be moved, The automatic ladder in cooperation with the ground is provided with a fixing bolt 35 which can be adjusted by preventing shaking at the ground surface and a safety plate 34 which supports the landing bolts 35. The safety lugs 34 are passed through the safety plates 34, The rubber plate hooks 38 are positioned at one side of the centering bolts 35 with elastic fixing force and the fixing nuts 36 are installed at two places facing the lower side of the attachment automatic ladder and two of the pillars of the four automatic ladders The ends of the column of the fixing bolts 35 tighten or separate the spacing space from the ground so that the lower ends of the fixing bolts 35 are connected to the ground and then the fixing nuts 36 are tightened together to form the landing bolts 35) As ever when landing the automatic safety ladder fixed location

The upper side of the winch frame 9 and the upper side of the second side 2 of the folding operation type ladder 2 and the bucking (winch lobe diameter) 48 and 49 are seated and combined in the fluorescent steel, The winch frame (9) The winch frame on the center of the column The winch frame (12) The direction facing the winch frame (9) The winch frame on the center part of the column (13)

The winch frame 9 and the folding type A-type ladder 50 are sandwiched between the bolt 14 and the bolt 15, And are tightened by nuts on the projecting threads on the rear side

The lower side of the winch frame 9 is provided with a winch fixed support plate 44 extending in the horizontal direction rear side and is installed on the winch fixed support plate 44 through four fixing portions of the winch 28 so that the winch 28 is engaged with the bolts and nuts In the

The upper thread of the roller fixing plate 16 is inserted into the upper surface winch row through hole 20 of the winch frame 9 and fixed to the projecting thread by the nut 9. The winch row moving roller 17 is inserted into the roller fixing plate 16, And the winch row moving roller 17 forms a rotational force while being attached to the winch row moving roller center shaft (bolt. Nut). Folding operation A type ladder The first side and the folding type A type ladder The second side and the connecting bolt 5 to secure the upper and lower moving spaces on one side of the winch string 21 on the outer surface of the second side of the folding type A-type ladder, and then the bucking is seated, and the winch frame 9 is rolled up, And through the threads projecting to the rear are fixed with nuts

One side of the left wing is inserted in the inside of the frame steel 25 in the inside of the steel steel frame so that the moving frame 25 can move in the inside of the winch frame 9 up and down. The lower side of the dough is provided with a protruding foot plate 26, and the upper side forms a winch string loop 24

The winch 28 attached to the winch frame 9 is formed such that a braking device and gears and a winch row roller barrel 29 motor (DC, AC) The length of the connecting line between the winch 28 operating power supply line and the cord 32 and the winch 28 motor operation switch (rising neutral drop) 1.5 times the length of the ladder and the operating switch is separated from the neutral position of the switch and the switch up position and the power transmitting position and the lower power transmitting position

The winch string 21 fixed within the winch string roller cylinder 29 attached to the winch 28 is lowered to the lower side of the upper winch row moving roller 17 and passes through the inside of the winch string attachment ring 24, And a winch string fastening portion (pressurized extension pipe) 23 is fastened and fixed to the distal end of the winch string 21 to form a knot. The winch string 21 is formed by binding the distal end to the winch string attaching ring 24

The automatic ladder according to the present invention is positioned at a position adjacent to a high position in order for the user to ascend to a high position. After the power cord 32 is connected, the ladder landing on the foot plate 26 is lifted up with the winch motor operation switch 33 raised The winch string 21 is wound around the winch row roller cylinder 29 while the power is transmitted to the winch 28 so that the winch string roller cylinder 29 is wound and the winch string 21 is connected to the winch string attaching ring 24, The automatic ladder user of the present invention located on the lower side of the foot plate 26 and the upper side of the foot plate 26 can be raised in the upper direction of the ground so as to be raised to a higher position

The downward power is transmitted to the winch motor operation switch 33 to unwind the winch string 21 to the reverse rotational force of the winch 28 and descend the foot plate 26 and the automatic ladder user located on the foot plate 26 in the direction of the ground The automatic ladder generates the rotational power of the power source rather than the user's magnetic force so that the automatic ladder user can be changed to the rising position or the neutral (temporary stop) lowering position with respect to the ground
