Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for pressure-bonding a gondola to a wall when the gondola is used to automatically paint or clean the wall.

[Conventional technology]

Recently, various methods have been proposed for automatically painting the exterior walls of buildings without relying on human power. Among them, there is a method of automatically cleaning and painting by suspending a painting gondola equipped with a coating machine or a polishing gondola equipped with a brush from a crane installed on the rooftop. has also been proposed.

However, if the pressure welding force is weak, for example in a gondola equipped with a paint sprayer, it will not be possible to get a beautiful finish without spots due to vibrations caused by outside wind or amplified vibrations during the operation of the installed equipment. Such problems arise.

In particular, in a cleaning gondola, which is equipped with a brush for polishing and cleaning a wall surface and performs polishing and cleaning by rotating the brush against pressure, it is impossible to perform cleaning without an appropriate pressure.

Other cleaning methods have been devised, such as a method using high-pressure water jetting at several hundred atmospheres and a method using shot blasting, but both of these methods have a large repulsion force, and if the pressure contact force is weak, the gondola may be damaged by the wall. Since the predetermined distance away from the body is not constant, uniform cleaning is impossible.

Furthermore, in the method using a roll brush, if the pressing force is insufficient, the brushing and cleaning work becomes impossible or, conversely, vibration occurs, which is a problem.

Therefore, as a solution to the above problem, other techniques are disclosed in, for example, JP-A-53-1240 and JP-A-56-31466, but in the former, a pressure weight is mounted on the gondola. Therefore, the weight of the gondola itself increases, and the crane, winch and rope for the suspension must be made larger than necessary. On the other hand, the latter uses a crane installed on the rooftop to attach a special pressure rope other than the gondola suspension rope to a weight on the ground through a pulley attached to the gondola to apply pressure to the gondola. During actual work, the gondola must be successively moved laterally along the wall surface, so the disadvantage is that the weight on the ground must be moved each time to the position where the gondola has moved.

[The problem that the idea aims to solve]

An object of the present invention is to provide a device that can easily and reliably press (press) a suspended gondola against the wall surface.

[Means to solve the problem]

In order to achieve this purpose, in the wall pressure welding device of the present invention, a slide arm storage housing housing an L-shaped slide arm to which a pulley for drawing a suspension rope is attached is installed between the inner surface of the parapet at the upper end of the outer wall and the outer wall surface. The suspension rope is then tightened and fixed with a handle-attached tightening screw, and the suspension rope is pulled horizontally inward by the pulley, thereby applying the necessary suitable pressure contact force (pushing force) to the gondola.

In addition, since the mounting position of the pulley is adjustable, the horizontal tension of the suspension rope can be easily adjusted, and when moving the gondola laterally, loosen the tightening screw and slide the L-shaped The upper surface of the parapet is rolled and moved by the required distance by the action of horizontally moving pipe rolls provided on the left and right sides of the outside of the arm storage case, and is then tightened and fixed again in the same manner as described above.

In other words, the present invention is an L that is provided with a slide arm pulley whose pulley position can be adjusted at the tip of the hanging part.
The L-shaped slide arm is nestedly housed in a slide arm storage housing having a slide screw provided therein, the L-shaped slide arm is connected to the slide screw, and a handle is attached to the slide screw. one pipe roll for lateral movement is attached to each of the left and right sides parallel to the slide arm storage housing, and a fastening fixture for clamping the inner surface of the parapet at the upper end of the outer wall and the outer wall. The present invention relates to a gondola wall press-welding device characterized by comprising:

[Effect]

In this way, since the suspension rope is pulled inward in the horizontal direction, a pressing force is forcibly applied from the gondola to the wall surface. Furthermore, even if the gondola descends several tens of meters downward, the pressing force can be maintained at the level necessary for cleaning or painting.

〔Example〕

Next, an embodiment of the wall press-welding device of the present invention will be described based on the drawings.

Fig. 1 is a side view schematically showing the entire wall pressure welding device, crane and gondola of the present invention, Fig. 2 is a front view taken from line A-A in Fig. 1, and Fig. 3 is a slide arm storage casing. 4 is a plan view taken along line BB in FIG. 3, and FIG. 5 is a side view showing the slide arm.

In FIG. 1, a crane 4 having a crane pulley 4A is installed on the roof of a building, and a gondola 3 is suspended by a suspension rope 2 along an outer wall 5 of the building. A slide arm storage housing 1 of the wall pressure welding device of the present invention is fixed to a parapet 6 at the upper end of the outer wall 5 by a fixture that clamps the inner surface of the parapet 6 and the outer wall 5, and an L-shaped slide arm 1C. A slide arm pulley 1A attached to the tip of the hanging portion of the suspension rope 2 pulls the suspension rope 2 toward the building.

The crane pulley 4A, the suspension rope 2, and the slide arm pulley 1A are paired as shown in FIG. 2, by which the left and right sides of one gondola are suspended. Pipe rolls 1J for lateral movement are in contact with the parapet ceiling 6A, one each on the left and right sides parallel to the slide arm storage housing.

In the embodiment of the wall pressure welding device of the present invention shown in FIGS. 3 to 5, an L-shaped slide arm 1C is nested in a slide arm housing 1, and a slider operated by a handle 1G. It is connected to the screw 1H. A slide arm pulley 1A is attached to the tip of the hanging portion of the L-shaped slide arm 1C via a mounting member 1B, and pulls the gondola 3 with the suspension rope 2 toward the outer wall 5 of the building. The gondola 3 is provided with wheels 3A, 3B, 3C, and 3D so that it can move up and down along the outer wall 5.

Pipe rolls 1J are arranged on both left and right sides parallel to the slide arm storage housing 1, and serve as guides when moving the gondola 3 laterally along the outer wall 5.
It is attached to the slide arm storage case 1.

Further, two tightening screw mounting arms 1D are attached to the slide arm storage case 1, one of which has a tightening screw that presses the upper end of the outer wall 5 from the front, and the other one has a tightening screw that presses the upper end of the outer wall 5 from the front. has a tightening screw that presses the inner surface of the parapet 6 from the rear. These tightening screw mounting arms 1D and tightening screws constitute a tightening fixture that clamps the inner surface and outer wall surface of the parapet 6. This fixture is used to adjust the fixing position of the handle 1E for operating the tightening screw, the presser plate 1I for pressing the wall surface, and the slide arm storage housing 1 and at least one arm 1D for attaching the tightening screw. It may further include a porous metal fitting 1F.

Next, a method of using the above-described embodiment of the apparatus of the present invention will be explained.

The pulley 4A of the crane 4 suspending the gondola 3 hoisted up to the top is sent out to a position slightly (for example, 400 to 500 mm) away from the wall 5.

Next, with the L-shaped slide arm pulley 1A lightly touching the suspension rope 2, turn and tighten the handle 1E of the handle-attached tightening screw, and tighten the pair of left and right L-shaped slides between the parapet 6 and the outer wall 5. The arm storage case 1 is firmly attached.

Next, by rotating the handle 1G, the L-shaped slide arm 1C connected to the opposite tip of the slide screw 1H, which is directly connected to the handle 1G provided in the slide arm storage case 1, is moved. Pull in and pull the suspension rope 2 horizontally toward the outer wall 5.

The wheels 3 of the gondola 3 are pulled in until the slide arm pulley 1A contacts the outer wall 5.
A, 3B, 3C, and 3D exert the largest pressure contact force (pressing force) on the outer wall 5.

In addition, on the top surface of the slide arm storage case 1,
A porous metal fitting 1F for attaching an arm 1D for attaching a handle tightening screw is fixed, and a pipe roll 1J for horizontal movement, which is approximately the same length as the width of the parapet ceiling 6A, is tightly attached to the parapet ceiling 6A on the left and right sides of the housing 1. One of each is provided in each state.

When moving the gondola laterally, the handle screw is loosened and the slide arm housing 1 is moved by the required distance on the parapet ceiling 6A using the pipe roll 1J.

Therefore, when setting the gondola to a predetermined position using only a crane, it was extremely difficult to make minute adjustments and the work took a long time.
Since the wall press-welding device of the present invention uses the L-shaped slide arm 1C as described above, not only the press-contact force of the gondola is increased, but also positioning can be facilitated and the working time can be shortened.

[Effect of idea]

As described above, by using the wall pressure welding device of the present invention, a sufficient pressure welding force can be maintained, and wall surface cleaning and painting work can be performed automatically and neatly without any spots. Furthermore, since the device itself is not complicated, complicated operations are not required not only when initially setting up the gondola, but also during lateral movement, and work can be done quickly, reducing work time.
