FIG. 1 is a schematic perspective view of the scaffolding luggage and the unloading machine according to the present embodiment. FIG. 1 is a schematic perspective view of the scaffolding luggage and the unloading machine according to the embodiment. Therefore, the fall prevention door 100 is simplified. FIG. 8 is a front view of the fall prevention door 100. As shown in FIG. 1 and FIG. 7, the loading machine on which the scaffolding luggage and the worker according to the present embodiment are mounted includes a loading mechanism and a fall prevention door 100. The loading mechanism will be described with reference to FIGS. 1 to 7, and the drop door 100 will be described with reference to FIGS. 8 to 10. The former lifting mechanism includes an electric hoisting winch 70, a lifting rail 10, a carrier 20, a fall prevention mechanism 30, and a fall prevention mechanism 200.

First, the electric hoisting winch 70 will be described. FIG. 2 is an enlarged front view of the periphery of the electric hoisting winch 70. Reference numeral 67 denotes a latch, and reference numeral 65 denotes a winch mounting bracket. First, the latch 67 is hooked on the adjacent horizontal cloth 3.3 on the scaffold 1 and fixed to the building 2.2 with a single clamp. The AA section is a section of the latch 67. Then, the winch mounting bracket 65 is placed on the latch bracket 67 and fixed. The upper portion of the winch mounting bracket 65 is fixed to support rods 64.64 at both left and right ends.

An electric hoisting winch 70 is hung on the center of the winch mounting bracket 65. The electric hoisting winch 70 is for winding and unwinding the hoisting wire 71 by an electric motor. A hook 72 is attached to a lower end of the winding wire 71.

As long as the electric hoisting winch 70 is attached to the winch mounting bracket 65, the electric hoisting winch 70 allows the members constituting the scaffolding luggage of the present embodiment and the unloader on which the worker can be placed. For example, it is easy to attach and detach the lifting rail 10, the loading platform 20, the door 100 safety wire 80, the balance weight 62, etc. to the scaffold 1.

A pair of left and right safety wires 80 and 80 are attached to a lower portion of the winch mounting bracket 65. The reason for providing the pair of safety wires 80.80 will be described later.

Next, the lifting rail 10 will be described. Fig. 2 is a front view of the unloading machine on which the scaffolding luggage and workers are placed. FIG. 3 is a V-V line astigmatism diagram. As shown in Figure 1.2.3, a pair of elevating rails 10.10 are attached to a pair of adjacent buildings 2.2 on the scaffold 1 by single clamps 11, respectively. It is preferable to use a channel steel for the lift rail 10.10. In addition, as a building to which the elevating rail 10 is attached, any pair of adjacent buildings 2.2 among the standing buildings 2 on the scaffold 1 in FIG. 2 may be adopted.

Next, the loading platform will be described. In FIG. 3, reference numeral 21 indicates a rectangular bottom plate. As shown in FIGS. 2 and 3, a plurality of fence posts 22 are attached as fences to the front, rear, left and right peripheral green portions of the bottom plate 21. A frame 28 and a lower frame 27 are attached to the upper end of each fence post 22.

As shown in FIG. 2-3, a hanger rail 99 is attached to an upper portion of a front end green of the bottom plate 21, and a door rail 23 is attached along the hanger rail 99. A scaffold-side sliding door 24 is attached to the door rail 23 so as to be freely opened and closed. A door 25 is attached to the center of the rear green so that the door 25 can swing open and close by a hinge or the like. A power switch 304 is attached to the ends of the door 25 and the sliding door 24 as a safety measure, and a thin iron plate is optimally used for the outer wall of the sliding door 24 of the loading platform 20.

As shown in FIG. 2-3, the upper and lower portions of the loading platform 20 at the left and right sides are mounted via mounting brackets 29.29 of two pairs of left and right rollers 26.26. Each of the two pairs of left and right rollers 26.26 is fitted to the pair of right and left lifting rails 10.10, respectively, and the 20 loading platforms can be vertically moved up and down.

Next, the fall prevention mechanism 30 that is in demand for the scaffolding luggage and loader of the present embodiment that can carry out work will be described. FIG. 5 is a front view of the fall prevention mechanism 30. As shown in FIG. 2 and FIG. 5, a pair of left and right support bars 31.31 is mounted on the carrier 20 in an upright state. A horizontal beam 32 is attached to each upper end of the pair of left and right support bars 31.31. As shown in FIG. 5, a pair of right and left mounting bases 33.33 are mounted on the upper surface of the beam 32.

As shown in FIG. 5, a link 4 1.41 is pivotally connected to each of the left and right mounting bases 33.33 by a pin at a base end thereof. The ends of the links 41.41 are each pivotally connected with a pin at the center of a hook-shaped holding cam 42.42. A pair of right and left pair of holding cams 42.42 are combined, and an ascending lift plate 43.43 is pivotally connected at both left and right ends. Further, as shown in the figure, a suspension plate 46 for lifting the loading platform 20 is provided, and a link 47.47 for connecting both sides of the suspension plate 46 and a rear portion of the holding cam 42.42 is connected by a pin. I am pointing.

The safety wire 80.80 is passed through a gap between the two holding plates 43.43 and the holding cams 42.42.

The left and right pins 45.45 are connected to the inside of the holding cam 43.43 and the holding cam. As shown in FIG. 2, a balance weight 62.62 is attached to the leading end of the holding plate 43.43 through the roller 63.63 by a weight wire 61. The holding plates 43.43 are constantly urged upward by the tension of the pair of left and right weight wires 61.61. By providing the balance weights 62 and 62, even with the small electric hoisting winch 70, the loading platform 20 can be moved up and down.

As shown in FIG. 2 and FIG. 5, when the loading platform 20 is hoisted by the electric hoisting winch 70, the suspension plate 46 is pulled upward, and the links 47.47 on both sides of the suspension plate 46, and thus the holding cams 42. The tip of 42 is supported by a pinch 48.48 at the center of the holding cam 42.42, and the tip is pushed down. Since the pin 45.45 at the end of the holding cam 42.42 is connected to the holding plate 43.43, the holding plate 43.43 is constantly pushed down when it is hung by the electric hoisting winch 70. It is.

A description will be given of a case where the hoisting wire 70 of the electric hoisting winch 70 is cut off, or a case where the electric hoisting winch 70 is broken during the elevating and lowering of the loading platform 20 and stops functioning and the loading platform 20 is dropped. I do. FIG. 4 is an explanatory diagram of the operation of the fall prevention mechanism 30. If the hoisting wire 71 of the electric hoisting winch 70 breaks, or if the hoisting wire 71 does not break and the tension of the hoisting wire 71 is loosened, the bed 20 drops rapidly due to gravity. However, at that moment, the holding plate 43.43 is pulled upward by the weight of the balance weight 62.62. Since the holding cams 42.42 are connected to the mounting base 33.33, which is mounted on the loading platform 20, by pins with links 41.41, the loading platform 20 is lowered and the holding cams 42.42 stand up at the same time. Then, the safety wire 80 in the gap between the holding cam 42.42 and the holding plate 43.43 is moved to the wire stopper 49.49 and the holding cam 42.42 in the holding plate 43.43. The safety wire 80 is clamped at the tip of the pallet, and it is possible to prevent the carrier 20 from dropping. To restore the normal condition, the hoisting wire 71 is fixed, and the loading platform 20 is suspended by the electric winch 70.

Next, a description will be given of the fall prevention mechanism 200 for ensuring that the scaffolding luggage and the unloading machine on which the worker rests are absolutely safe for a person to get on. As shown in FIG. 6 and FIG. 7, it is set and fixed on the frame 28 on the upper part of the 20 loading platforms. Then, a hook-like holding cam 203 is connected to the mounting table 201 with a pin by a link 220 for combining two sheets.

As shown in FIGS. 6 and 7, a wire stopper 205 is fixed inside the holding plate 204, and a safety wire 80 is inserted between the holding cam 203 and the wire stopper 205. A spring 206 is provided at an end of the holding plate. The holding plate 204 is always moved upward by a spring as shown in FIG. 7, and the safety wire 80 contained in the holding plate 204 is fixed to the holding cam 203 and the holding plate. Wire stopper 205 is used to hold it lightly. A frame 208 connected by pins 208 connecting the mounting table 201 and the holding cam 203 and pins 207 connecting the holding cam 203 and the holding plate 204 is installed.

Next, an up switch 300 and a down switch 301 are provided on both sides of the frame 209. The frame 209 and the operation handle 303 are connected by a pin 302. A handle stopper 305 is attached to the tip of the operation handle 303. A power switch 304 is provided below the holding plate 204 as shown in FIGS. FIG. 7 shows a state in which the power switch 304 is turned off and the unloader is stopped.

Next, the operation procedure of the lifting machine on which the luggage for lifting and the worker is placed will be described. 7, the holding plate 204 is always moved upward by a spring 206 and the wire stopper 205 and the holding plate cam 203 inside the holding plate lightly narrow the safety wire 80 as shown in FIG. I have When the operating handle 303 is turned clockwise and pressed as shown in FIG. 6, the holding plate 204 is lowered by the action of the frame 209 connected by the pins 207 and 208, and the holding cam 203 and the wire stopper 205 are moved. There is a gap between them and the safety wire 80 is not pinched. Then, the tip of the operation handle 303 presses the protrusion of the switch 300 and simultaneously presses the power switch 304 below the holding plate 204. Then, power is supplied to the switch 301 and the power switch 304, and the carrier 20 is raised. Similarly, when the operation handle 303 is pressed to the left, the protrusion of the switch 301 is pressed. Similarly, when the protrusion of the power switch 304 is pressed, a current flows through the electric hoisting winch 70 and the carrier 20 is lowered.

FIG. 7 is a view showing a state where the unloader 20 is stopped. If for some reason the hoisting wire 71 does not break and the carrier 20 falls, the fall prevention mechanism 200 will be activated immediately, and at the same time the upper drop prevention mechanism 30 will be activated, and the safety wire 80 will be narrowed at three places. To prevent the carrier 20 from dropping. Also, when ascending or descending on the carrier 20 at the work site, immediately release the operation handle 303 if it is dangerous. By releasing the hand, the power switch 304 is cut off as shown in FIG. 7, and the holding plate 204 is moved upward and the holding cam 204 holds the safety wire 80. For normal operation, the protrusion of the power switch 304 is pushed down, and the operation handle 303 is turned clockwise, so that the loading platform 20 rises to a normal state.

Next, the fall prevention door 100 will be described. FIG. 8 is a front view of the fall prevention door 100. As shown in FIGS. 8 and 9, the fall prevention door is composed of a pipe 140 for a squeeze and a door 130.

As shown in the drawing, a pipe 140 for a whirlpool is obtained by integrating four branch pipes 142 into a horizontal pipe 141 by welding or the like. Pipe diameter is 17. A pipe of about 2 mm is light and suitable. The power switch 304 is attached at the center.

At each of the left and right ends of the horizontal pipe 141, two pairs of left and right branch pipes 14.2.142 are reinforced with their brackets, respectively, and the tip thereof is a single clamp 151, four places of welding, etc. It is fixed with. A hanger rail 143 for opening and closing the door 130 is fixed to the bracket, and thick pipes 144. 144 is attached and the upper end contains a pin. Moreover, the angle formed by the bifurcated pipe 142.142 from the horizontal pipe 141 is 90 degrees. These are integrated as shown in FIG.

As shown in FIG. 8, a single clamp 151 is attached to a building 2.2 adjacent to the scaffold 1 at a position corresponding to each scaffold plate 5 at a height. By attaching the pipe 140 for scoop, the scaffold 1 becomes very firm even if the bracing pipe is removed.

Next, the door 130 will be described. As shown in FIG. 8, the pipe 140 is attached to a height corresponding to each scaffold 5. Since the hanger rail 143 is provided, the door 130 has two sets of doors 130 as shown in the figure, and a door wheel 131 is mounted on the upper part. The door 130 has a stop plate 132 attached so as to surround the lower hanger rail. A power switch 304 is mounted at the center of the hanger rail 143. Even if the operation handle 303 is turned while the door 130 is open, no current flows. The outer wall of the door 130 is optimally made of a thin iron plate for safety.

Next, as shown in FIG. 8, when the door 130 is closed, a gap is formed on both sides of the door 130, so that the thin pipe 145 is inserted into the thick pipe 144 attached to the pipe for the haute.

Once the fall prevention door 100 is attached to the scaffold 1, the effect of preventing the worker and the unloading material from falling is provided, and it is safe even if the loading platform 20 is moved up and down.

Next, the operation and effects of the scaffolding luggage of the present embodiment and the unloader on which the worker can ride will be described. As shown in FIGS. 1 to 10, the hoisting wire 71 is fed out by the electric hoisting winch 70, and the carrier 20 is lowered along the pair of elevating rails 10.10 to be lowered on the ground. Then, the outer door 25 of the carrier 20 is opened, an operator or a load is placed on the bottom plate 21, and the outer door 25 is closed. When the hoisting wire 71 is wound up by the electric hoisting winch 70, the carrier 20 is moved to the pair of lifting rails 10. Ascend along 10.
