Description

[Detailed description of the invention] door The present invention relates to an emergency stop device for a hanging basket.

If the hanging rope breaks while the basket is being moved up and down along the guide rail, the basket will fall, which is dangerous.

Therefore, the present invention provides an emergency stop device that can prevent a basket from falling into a sore even if the hanging rope breaks.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1st
In the figure and Fig. 2, (1) is the lower part (2) and the upper part (
3) Vertical in the distance! ! A pair of guide rails with a U-shaped cross section are arranged along (4), and (S) is a basket that can be raised and lowered along the guide rails (1), and an emergency stop device (6) is installed on the back side of the basket. It is arranged.

(η is a zero-order crane device installed on the support platform (8) on the upper stage (3), which has a rotatable davit body (9), a winch device (Z), and a suspension rope (B). The details of the emergency stop device (6) will be explained based on FIG. 8 to FIG. Figures and @@■

1B), a cylindrical body (12C) and a protrusion (1!D) are connected in a straight line. Also, IIB rod - (u!A
) and the II rod (1B) are arranged so as to form a cross shape when viewed from the plane. OS is the first If! The base is fixed to the basket (6) facing 111 fm below (1!A), and the trout is placed between the upper and lower parts of the first rod (1!A), respectively, in the basket. ), a pair of brackets whose rings are inserted through the long holes of the first rod (1!A), and a pair of support shafts whose both ends are supported by the respective bracket shafts; A suspension ring connected to the upper end of one rod (11!A) via a bottle ■, to which the lower end of the suspension rope is connected, is attached to each guide rail (1) at both ends of the base (to). Support plates fixed opposite each other, rings are reinforcing ribs of each support plate (2), rings are fixed to each support plate (1), and lower parts inserted into each guide rail (1) are fixed to the frame. The ridge, - is a total of four fixed shafts fixed to the back of the basket (5) at the upper and lower positions on both sides of the second rod (11B), and (2) is the central boss part (1!A), respectively. A link is externally fitted onto each fixed shaft so as to be rotatable in the directions of arrows (A) and CB), and one end (IIB) is connected with a pin to the upper and lower parts of the second rod (11B), respectively, and the link is connected downwardly. Both sinks facing each other are parallel to each other.

(2) is a pair of lifting rods whose upper and lower ends are connected to the other end (28C) of both rods facing each other in the vertical direction, and which are inserted into each guide rail (1) and fixed to each of the above-mentioned It is located directly below the horizontal four. @ stands for each lifting rod (2) above.
The bearing frame is fixed to the upper end via a height-adjustable connecting rod 4, and the ring is rotatably fitted into the through hole at the lower end of the horizontal shaft supported by each bearing frame (2). Two pairs of arms (2) are fixed to the upper end of each arm (2) and each fixed side sl! The moving side side of the upper convergence located between the 4th side and the inner side of the guide rail (1),
(2) is a receiving plate extending horizontally from the lower end of the second rod (IIB), ■ is a fixed piece fixed to the back of the basket (5) below each receiving plate (2), and Sakaki is A spring is stretched between each fixed piece and each receiving plate and pulls the actuating member downward.

The operation of the above configuration will be explained. First, when lifting the basket φ) brought to the position of the imaginary line in Figure 2, use the hanging rope ■
The zero-order winch device shaft that connects the lower end of the rope to the suspension ring and the trunnion member at the upper end of the Neusket (5) is operated to wind up the suspension rope (B). Then, the actuating body (2) is first pulled up against the spring, resulting in the solid line m5aa state. In this situation, each movable side wedge wheel is lowered via the link (2), the lifting rod 1 connection rod (2), the bearing frame and the arm, and each displacement wedge (2) and the guide rail (1) are lowered. 111st is formed between the inner surface of the Therefore, if 1<Sket(2), the value will rise smoothly.

Next, when the hanging rope (c) breaks while the basket is being raised and lowered, the actuating body (2) is pulled down by the spring.
As shown by the imaginary lines in FIG. 1, each link (2) rotates in the direction of arrow (2) about the fixed shaft - as a fulcrum, and lifts up both elevating rods (2). Then, as shown in Figure @6 and Figure IIs, each moving side II! - is raised and pushed into the darkness with a fixed number of buildings - and guide rails (illusions).

As a result, the basket (i) is fixed to the guide rail (1) immediately after the suspension rope is cut, and does not fall.
In the trench where the lower stage (j1) was placed by descending along the old ζ, the protrusion (1!D) of the actuating body (b) was
) hits the lower tier and the actuating body (b) force is raised, so even if the sling rope is loosened, each moving wedge does not rise, and each moving wedge llIh wedge ■ will not be pushed in between fixed side sl@ and guide rail (11), therefore emergency stopping force < f) s force 1
However, according to this embodiment, maintenance and inspection of the basket (5) is easy.

As described above, the suspension/skewart emergency stop device of the present invention has a simple structure consisting of an operating body, a fixed structure, a link mechanism, and a movable side wedge, and is difficult to break down. . In addition, (when the suspension cable breaks during the ascent and descent of the scale, the actuating body descends and the moving wedge is pushed between the fixed bridge and the guide rail by the link mechanism.) Immediately fixed to the guide rail and will not fall.
