Description

A tracklayer platform has adsorption operation.

The present invention is characterized in that an opening / closing magnet made of a permanent magnet in an infinite orbit is provided so as to be directly attracted to an endless track, an accompanying driving and an attracting surface, and a control frame for controlling a magnetic force of the opening / closing magnet is provided in a part of the platform frame, The present invention relates to an infinite-orbit platform in which a control section controls the magnetic force of an opening / closing magnet by a driving force to travel on an excellent attraction force, but does not generate a driving load.

There is a demand for an apparatus and a method capable of performing an adsorption traveling for working on an inclined and curved surface such as a ship hull and a steel structure surface.

Due to this necessity, various methods of adsorption traveling are known.

However, since a coil winding is often used in order to constitute an electromagnet having a strong attraction force, the magnet is not easy to use due to its large volume and weight, In addition, a complicated device for opening and closing a current, etc., is excessively expensive to manufacture, and there is a problem in that it consumes electric energy and operates.

In a method of adsorbing and traveling by a permanent magnet, a method is disclosed in Korean Patent No. 10-1998-0705449, No. 10-0599402, No. 10-2013-0107431, No. 10-2009-0013211, No. 10-2009-0120298, etc. .

In the method in which the magnet is fixed as in the known method, the magnet is arranged to be spaced apart from the attracting surface to move the platform, so that the magnetism efficiency of the magnet is lowered and the attraction force is reduced. Also, since there is no frictional force, There was no problem.

This is evidenced by the coulombic law in which the magnitude of the magnetic force is inversely proportional to the square of the distance.

In Korean Patent No. 10-1996-0705786 and No. 10-2009-7015887, which solve such a problem, a method of directly attracting a attracted surface of a magnet and preventing slip by increasing frictional force is provided.

In the method in which the magnet is directly adsorbed, the magnetic force is continuously maintained to generate the driving load, and in the method of increasing the frictional force, the driving load due to the frictional force is generated.

The present invention has been made to solve the above problems,

And the magnet is attracted directly to the attracting surface so that no slip occurs in the high inclination running and the magnetic force of the magnet is controlled by the driving force of the endless track so that the driving load becomes And an economical method of not consuming extra energy for generating magnetic force is provided.

In order to achieve the above object,

A plurality of open / close magnets constituted by permanent magnets in an infinite orbit and rotated by 90 degrees and turned on / off by a magnetic force are provided in a structure that is driven in parallel with the endless track,

At this time, the opening and closing magnet is provided so as to be directly adsorbed to the adsorption surface,

And a control port for rotating the permanent magnet by 90 degrees in an endless track frame,

When the opening / closing magnet driven by the infinite orbit enters the adsorption surface, it generates a magnetic force and controls the magnetic force to be lost at a position where the adsorption surface is pulled out, so that the driving force is not generated while the adsorption traveling with the strong adsorption force.

Also, the opening / closing magnet is provided through the infinite orbit and is directly adsorbed on the adsorption surface.

In addition, the drive pulley and the idler provide grooves through which the opening and closing magnets pass.

In addition, the control section provides a method of operating with a driving force of an infinite orbit.

Further, the present invention provides a method of preventing reverse traverse when the endless track is stopped during an inclined running.

Also provided is a platform structure having a frame supporting the endless track.

The platform also provides a method of mounting various work equipment.

The adsorption traveling caterpillar platform according to the present invention can easily carry out adsorption traveling in a place where people are difficult to access such as the surface work of a large ship or a steel structure, so that the target work equipment is mounted on the platform, Saving effect can be obtained.

Figure 4 is an application diagram in which a work equipment is mounted on a platform according to the present invention;

In the present invention, an open / close magnet is a magnet which is composed of two or more permanent magnets as shown in Korean Patent No. 10-1980-0002955 and turns on or off by a magnetic circuit when rotated by 90 degrees. The magnet is normally a switching magnet, Switching magnet, magnetic base, and the like.

Hereinafter, it will be described in detail based on the attached data.

1 shows the ON / OFF function of the open / close magnet. The open / close magnet 10 repeatedly connects and disconnects the magnetic circuit (magnetic circuit) with the permanent magnet 11 rotated 90 degrees through the turn lever 20, And causes loss.

Fig. 1A is a configuration diagram of a general open / close magnet. Fig. 1B shows a state in which the magnetic force of the open / close magnet is off, and Fig.

FIG. 2 is a perspective view of an endless track of an infinite orbital platform traveling according to the present invention. The open / close magnet 10 is mounted on an endless track 30, such as an endless track 30, So that the magnetic force of the opening / closing magnet 10 can be utilized as a maximum attraction force.

In the present invention, the drive pulley 50 and the idler (not shown) are provided with the passage grooves 60 so that the upper portion of the opening / closing magnet 10 protruding into the endless track 30 can easily pass through.

In the endless track frame 70 of the present invention, a control port 80 for controlling the open / close magnet 10 is provided.

When the drive pulley 50 and the endless track 30 are driven in the clockwise direction by external power, the open / close magnet 10 is driven together with the endless track 30 to enter the attracting surface 40. At this time, The turning lever 20 of the first rotating shaft 10 is caught by the first control port 81 and rotated by 90 degrees so that the opening and closing magnet 10 generates a magnetic force to be attracted to the attracting surface 40, The turning lever 20 is rotated by 90 degrees by the second control port 82 to lose the magnetic force and drive the upper portion along the outer periphery of the driving pulley 40. [

When the platform 100 is constructed as a large-sized structure, if the vehicle stops at a high inclination of 60 degrees or more, it can be driven backward by gravity.

This is because the endless track is reversely driven by gravity, and the rotation lever 20 of the opening / closing magnet 10 is controlled by the control port 80, so that the repetitive action of releasing the magnetic force of the opening / closing magnet 10 occurs.

In order to prevent such reverse movement, it is preferable to use a speed reducer with a deceleration ratio of 30: 1 or more which is difficult to reverse drive in a motor (not shown) for driving the drive pulley. If the current is applied to the drive motor, the brake is released. If no current flows to the drive motor, the brake is braked.

The platform 100 constructed with such a system can travel without slip and drive load to a magnetic body such as an iron plate due to the magnetic force and friction force of the opening and closing magnet 10, and can be used for the marine plant work such as ship hull industry, marine plant such as drill ship, It is possible to carry out the work with the aimed work equipment 90 such as maintenance, pipe pipe work, external work in a large tank, hull lifting, etc., so that it is possible to replace a work with many disasters.
