Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a chair-type gondola for high-altitude work, which is used for painting walls of buildings, etc., and is moved up and down using a pulling rope.

<Conventional technology> Conventional chair-type gondolas for working at heights are lifted and lowered by hooking a single tow rope fixed to the roof of a building onto a rope winding pulley and rotating the rope winding pulley using a motor, etc. Those with a structure that allowed them to move were mainly used.

Problems that KUHAKATSUI attempts to solve〉 Therefore, since the gondola can move up and down, the working area is only free in the vertical direction, and in the lateral direction, there is a relatively narrow width within which hands and tools can reach, centering on the rope. was limited to.

If the area required for one work was outside of this range, a person had to get off the gondola and move the upper rope anchoring position. This work is difficult, and if the work area is large, it must be moved frequently, which is a major factor in reducing efficiency.

As a way to solve this inconvenience, a method has been proposed in which a guide rail is installed on the rooftop so that the gondola can be moved while suspended, but the equipment cost would be enormous. Furthermore, depending on the structure of the rooftop, there may be places where it is impossible to implement the method due to obstructive protrusions.

<Means for Solving the Problems> Therefore, in the present invention, a chair-type gondola that is raised and lowered by a traction rope hung on rope winding pulleys is provided with a pair of rope winding pulleys (2a) on the left and right, which is different from the conventional one. (2
b), and two traction ropes (5a) (5b) fixed at an interval in the upper part can be operated by the separate rope winding pulleys.

In a chair-type gondola for working at heights with this structure, the upper fixed position (P) of the towing rope remains the same, and even while riding on the gondola, the upper fixed position (CP) on both sides as well as the upper and lower parts can be fixed. ) can move widely left and right.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of a chair-type gondola for high-altitude work according to the present invention, and FIG. 2 is a rear view of the gondola during work.

As seen in these figures, the chair-type gondola for high-altitude work of the present invention has a seat at the top of the main body (1),
There are frame legs below it, and a pair of rope winding pulleys (2a) on the left and right are located between the seat and the legs.
(2b) is provided. This rope winding pulley (2a
) (2b) are connected to a motor (3) provided between them via clutches (4a) and (4b). Two tow ropes (5a) (5b) fixed at a distance from each other at the upper part are respectively hung on the separate rope winding pulleys (2a) (2b) so that they can be operated.

The chair-type gondola for high-altitude work of the present invention is equipped with a rope-winding pulley (2a) in consideration of safety during lifting and lowering using the tow rope (5a) (5b) hung on the rope-winding pulley (2a) (2b). ) Guide pipes (6a) (6b) are provided which are partially bendable upward from (2b), and up/down switches (7a) (7b) are provided at their bases.

When the device of the present invention is used, the workability is very good, as can be seen in Fig. 2. In order to move up and down from the position shown by the solid line, the left and right rope winding pulleys (2a) are used.
(2b) are rotated at the same time. Also.

To move to the right or left as shown by the two-dot chain line, press the up and down switches (7a) and (7b) at the same time and change the direction.

Alternatively, it is preferable to press only one of the up and down switches (7a) and (7b) to rotate only one pulley.

In the above embodiment, a winding pulley is used for vertical and horizontal movement, but the pulley is, for example.

A pulley with a groove formed on its outer periphery has a traction rope wound around the groove, one of which becomes the traction side, the other the relaxation side, and the middle part is pressed by a pressure roller (for example, the stake is 1$). 857-240), etc., which are superior in terms of safety, can be used.

<Effects of the Invention> The chair-type gondola for high-altitude work having the structure described above has a simple structure and is therefore easy to manufacture.

Painting work over a wide range of areas using a chair-type gondola, which was previously impossible, can now be carried out freely while the top of the tow rope remains fixed, and moreover, while riding on the gondola. Since it is supported by two tow ropes, it is safer and provides much better stability during work than the conventional single-rope type.
