Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polishing device used for pre-painting and surface preparation of the surface of a rope plate, such as a ship's block.

Conventionally, as shown in FIG.
When performing pre-painting treatment and substrate preparation on each surface, a worker manually sands each surface with an angle sander. However, according to the above method, the worker is required to polish the outer panel 2 side, the longitudinal material 3 side, and these fillet welds 4, and the worker must polish each separately, and the work must be done manually. This causes wasted labor, and since each of the above tasks requires bending over or sitting on the ground, it causes back pain for workers.Furthermore, workers use tools directly, which causes them to inhale dust, etc. There was a problem.

Therefore, an object of the present invention is to provide a polishing device that can solve the above problems.

That is, the present invention includes a first polishing tool having a wire brush for polishing the horizontal surface of the member to be polished and a drive device for driving the wire brush, which is mounted on a traveling cart that is movable over the member to be polished by a traveling device;
A wire brush for polishing a vertical surface of a member to be polished and a second polishing tool having a drive device for driving the wire brush are each held swingably via a holder, and each of the polishing tools and the holder are and a magnet for adhering to the vertical surface of the member to be polished and guiding the traveling vehicle along the vertical surface. This polishing device is characterized by being equipped with a net roller, and according to this configuration, when the traveling carriage is set on the horizontal surface of the member to be polished and the respective drive devices of the traveling carriage and each polishing tool are operated. , the traveling cart automatically starts traveling while being guided along the vertical surface by a magnetic roller adsorbed to the vertical surface of the member to be polished, and each polishing tool, that is, the first and second polishing tools, The horizontal and vertical surfaces of each member to be polished are simultaneously polished. At this time, the first and second
Each polishing tool is pressed against the surface to be polished by a biasing means. In addition, since the first and second polishing tools are swingably held via a holder, if the horizontal and vertical surfaces are not correctly placed at a 90 degree angle, they can be adjusted to accommodate both angles. Fine adjustments will be made.

Therefore, according to the present invention, the following effects can be expected.

(i) It has a first polishing tool for polishing a horizontal surface and a second polishing tool for polishing a vertical surface, and since a traveling cart traveling on a horizontal surface is guided along the vertical surface by a magnetic roller, It is possible to polish both the vertical surface and the vertical surface at the same time.

(ii) Each wire brush has a biasing means for pressing the surface to be polished, and since the magnet roller is attracted to a vertical surface, the wire brushes are applied with a predetermined force by each biasing means for polishing horizontal and vertical surfaces. It can be pressed against horizontal and vertical surfaces. In particular, the second polishing tool for vertical surface polishing needs to generate a pressing force in the horizontal direction, but this is possible with the biasing means, and the magnetic roller can maintain the horizontal position of the second polishing tool. , it is possible to polish vertical surfaces well.

(iii) Since each polishing tool is held in a swingable manner, it can be used even when the horizontal and vertical planes are not at exactly 90 degrees, and in combination with the biasing means, it can be applied to each polishing surface in a good manner. Polishing is possible under contact conditions.

(iv) Since each polishing tool has a drive device, the power transmission path from the drive device to the wire brush can be simplified.

(v) Therefore, the horizontal and vertical surfaces of the workpiece to be polished can be polished automatically and at the same time with good contact, which greatly improves work efficiency and eliminates tedious work from the operator. This also eliminates the need for workers to inhale dust, which has a significant effect on safety and health.
