Description

Magnetic multistage auto pole.

The present invention relates to a multi-stage automatic pole using a magnetic force, and in particular, unlike a general stand pole, the multi-pole automatic pole has been invented so as to be suitable for a golf course, various sports facilities and road type street lamps, By inserting the pawl into the stationary pole 1 and minimizing the height, it is possible to easily manage the installation such as the lighting facility installed at the upper end of the lifting pawl, to secure the safety of the operator, and to reduce the management cost. Further, according to the present invention, an electromagnet is installed at each lower end of a lifting pawl inserted into a fixed pawl so that the lifting pawl can be raised or lowered step by step by the supply of power, and the speed of the lifting pawl can be easily adjusted The present invention relates to a multi-step automatic pawl using a magnetic force.

Currently, stand type poles are generally used at home and abroad, but in the case of stand type poles, they are fixed type, and the pole height is high, which makes it difficult to manage. In the case of stand-up type poles, it takes up a certain amount of floor space. Several techniques have been developed to improve the drawbacks of such stand-type pawls.

For example, Korean Registered Utility Model No. 0232968 relates to a light tower transfer device having a plurality of conveying rollers for guiding conveyance of cables in order to improve the difficulty of post-management of the standpipe, And a plurality of conveying rollers formed between the illumination support member and the illumination support member installed at an angle and having a plurality of conveying rollers, the illumination support member having a through hole for guiding the conveyance of the electric cable for supplying power to the illumination lamp A plurality of illumination lamps mounted on one end of the illumination assistant support member and a plurality of illumination lamps mounted on the illumination assistant support member, And is slid along the illumination fixture member while generating an elastic force when the transfer member is vertically transferred It consists of a king-operating locking members.

However, the present invention differs from the above-mentioned design in that the multi-stage automatic pole provided with the lighting tower can induce a step-up or step-up, and the elevating pole itself is raised and lowered by the magnetic force generated in the electromagnet, It is noise-free, power-saving invention.

In Korean Registered Utility Model No. 0421175, there is disclosed a technique relating to an automatic pole movement device, which comprises a body having a predetermined length and having a motor therein, a gear portion provided on a rear surface of the motor of the body, The motor being rotatably driven through the motor in the longitudinal direction and rotated by the operation of the motor, one end of which is rotated in association with the gear to form a thread on the outer periphery by a distance from the portion exposed to the outside of the motor to the other end And a plurality of gears, each of the gears having a first end and a second end, the second end being connected to the first end and the second end, And is extended from the gear to penetrate the inside of the rotation shaft Connected through a number of pole rings and the wire hole, and the other end is the outermost configuration characterized in that it comprises a wire which is fixed to the lower end of the pole.

However, while the prior art is constituted by a motor and a screw, the present invention is characterized in that electric power is supplied to the electromagnet to sequentially raise the lifting pawl, so that the present invention and the above- It shows a remarkable difference.

In the case of the stand type pole, it is fixed type, and when the facilities installed at the upper part of the pole, for example, the light fixture, is installed, the height of the pole is high when the light fixture breaks or the light fixture is replaced. In order to solve such a problem, the present invention adopts the technique of raising and lowering the multi-step automatic pawl by the magnetic force, thereby reducing the volume of the equipment than the stand type using the force of the conventional motor, It is easy to manage because it can be managed by lowering the height. In addition, it is possible to reduce the volume of the auxiliary equipment and facilities of the pole, thereby reducing the cost. Also, the noise environment can be solved because the multi-step automatic pole has little noise when it ascends and descends.

In order to solve the above-described problems, the present invention provides a method of inserting a cylindrical lifting pawl, which is smaller in diameter toward the inside than the cylindrical fixed pawl (1), in a stepwise manner to gradually raise or lower the multi- .

In order to raise or lower the lifting pawls inside the fixed pawls 1, power supply rails 22 and 23 are designed along the fixed pawls or the wall surfaces of the lifting pawls to supply power to the electromagnets formed on the lifting pawls, When the sixth lift-up pawl 7 rises due to the supply of power, the upper power supply rail exposed at the lower protrusion of the sixth lift pole and the lower end exposed at the upper- The power supply rail portion is brought into contact with the current flowing to the fifth lifting pawl 6 to raise the fifth lifting pawl. When the lifting pawl rises in the height direction and becomes completely high in this way, the height of the multi-stage automatic pawl is maximized. The upper and lower power supply rails of the fixed pawl and each of the lifting pawls meet with the lower power supply rail portion to shield the power supply rail portion with an insulating material so that no current flows through the fixed pawl and the lifting pawl when a current flows, In order to facilitate the movement of the lifting and lowering pawls, a steel wheel 31 is provided at the lower end of each lifting and lowering pole.

The operation of the lifting pawl of the multi-stage automatic pawl according to the present invention includes the steps of supplying electric power to the electromagnets through the power supply rail portion provided along the wall surface of the lifting pole, generating magnetic force in the electromagnet 21 installed in the lifting pawl, The elevating pole power supply rail portion of the upper portion and the lower elevating pole power supply rail portion meet each other and the elevating pole is elevated in order, And if the magnetic force is not generated, the lifting pawl is lowered stepwise and inserted into the fixed pawl.

As described above, according to the present invention, unlike a general stand type pole, the multi-step automatic pawls have a multi-stage pole in the longitudinal direction so that each of the lifting pawls slides into or out of the lifting pawl having a large diameter The height of the multi-step automatic pawl is adjusted so that the upper end portion (9) of the multi-stage automatic pole can be used as a lighting facility of a large stadium such as a golf course, a baseball field, a soccer field, It is possible to use the multi-stage automatic pole to reduce the height of the pole so that it is suitable for the stadium. It can facilitate post-management and maintenance of the lighting facilities and observation facilities, clean the environment of the stadium and help secure the safety of workers . In addition, when the multi-step automatic pawl ascends or descends, it uses magnetic force, so there is almost no noise, so the environment problem can be solved. In addition, the multi-stage automatic pole using magnetic force can reduce the volume of the equipment and control the rising and falling operations more easily than the stand type mold using the motor, and thus the cost can be greatly reduced.

In FIG. 1, a cylindrical fixed pole 1 forming a body of the multi-stage automatic pole is embedded and fixed in the ground at a predetermined depth, and a lifting pole having a small diameter of the cylinder is provided inside the fixed pole 1. The first lifting pawl 2 is slidably inserted into the fixed pawl 1 and the second lifting pawl 3 is slidably inserted into the first lifting pawl 2. In this way, A plurality of lifting pawls can be inserted as needed. In the present invention, a plurality of lighting lamps are provided at the upper end of the sixth lifting pawl 7 to constitute a multi-stage automatic poultry which can be used in a soccer field, a baseball field, or a golf course. The first to fourth elevating pawls (2) to (6) are inserted stepwise in the fixed pawl 1, and the elevating pawl inside the fixed pawl is raised stepwise by the magnetic force, The first and second lifting and lowering pawls 2 to 6 are inserted into the fixed pawl 1 to reduce the height of the automatic pawl 1 .

In the case of fixed stand type pole, pole height can not be adjusted like the multi-step automatic pole, so it is inevitable to directly work up to the end of the pole for maintenance, And there is a problem that costs are incurred when an elevated ladder is used.

Fig. 2 is an actual state of use in which the multi-step automatic pawl is lifted up to the maximum height direction and stretched.

In order to solve the above-described problems, the present invention provides a method of inserting a cylindrical lifting pawl, which is smaller in diameter toward the inside than the cylindrical fixed pawl (1), in a stepwise manner to gradually raise or lower the multi- .

In order to raise or lower the lifting pawls in the fixed pawl 1, the power supply rails 22 and 23 are designed along the fixed pawls or the respective lifting pole wall surfaces, When the sixth elevating pawl 7 rises, the upper power supply rail and the fifth elevating pole 6, which are exposed at the lower protrusion of the sixth elevating pole, The lower power supply rail portion exposed to the upper projection portion of the second power supply contact portion is brought into contact with the fifth lift pole 6 so that the fifth lift pole is raised and the sixth lift pole is blocked by the protrusion. In this way, power is supplied from the sixth lifting pawl 7 to the first lifting pawl 2, and power is supplied to the electromagnet 21 installed at the lower end of each lifting pawl, The height of the multi-step automatic pawl is maximized when the lifting pawl is fully extended. The current supplied at this time is 12 V, and the intensity of the current is selected and used as needed. In order to reduce the height of the multi-step automatic pawl, the lifting pawl is inserted into the fixed pawl 1. At this time, when the power supply to the electromagnet of the first lifting pawl 2 is stopped, the first lifting pawl 2 is inserted into the fixed pawl 1. That is, when the power supply is interrupted by the operation of the power switch (not shown), the supply of current to each of the lifting pawls is interrupted and the first to sixth lifting pawls (2) to (7) And the height of the multi-step automatic pawl is lowered by inserting the lift pole of the outermost portion into the inside of the fixed pole. The fixed pole and the upper power supply rail of each of the lifting pawls and the lower power supply rail are connected to each other so that no current flows through the fixed pole and each of the lifting pawls when the current flows, The power supply rails 22 and 23 are shielded by the insulating material 24 and a steel wheel 31 is laid on the lower end of each lifting pole in order to facilitate the movement of the lifting pawls by the magnetic force by the power supply. In order to engage and fix the upper and lower ends of the lifting pawls, projections are formed on the lower end of the upper lifting pawl and the upper end of the lower lifting pawl so that the projections of the upper lifting pawl engage with the projections of the lower lifting pawl, At this time, each of the upper and lower lift poles is fixed so as not to be separated from each lower lift pole.

Power supply rails 22 and 23 are provided on the wall surfaces of the first to sixth lift pawls 2 to 6 in order to supply electric power to the electromagnets installed at the lower end of each of the lift pawls, , The lower elevating pole current flows in contact with the power supply rails of the lower elevating pole. At this time, a magnetic force is generated in the electromagnet and the elevating pole is raised by this magnetic force. The power supply rail unit allows the current to flow only at a portion where the lower end and the upper end of each of the lifting pawls are in contact with each other, and each of the lifting pawls sequentially rises in accordance with the supply of power.

As another embodiment of the multi-stage automatic pawl of the present invention, an electromagnet may be installed at the upper end of each of the lifting pawls, and the operation principle thereof is the same. However, the design can be performed only by changing the design according to the position of the electromagnet.

As described above, since the power is supplied to the electromagnets provided at the lower ends of the respective lifting pawls and the lifting pawls are operated to move up and down by the generated magnetic force, unlike the conventional stand type, Can be greatly reduced. In addition, height of lighting facilities can be freely set by adding elevator pole in a big stadium such as golf course, soccer field, baseball field, etc. In order to reduce the number of elevator pole or reduce the size in indoor such as gymnasium, So that the height of the multi-stage lifting and lowering pawls can be appropriately adjusted. The multi-stage automatic pole with the lighting fixtures can adjust the height of the pole to the desired height in the outdoor or indoor environment. When the pole is not used, it is placed on the ground and covered with a cover or the like, Since it can be bought on the inside surface, the surrounding environment such as the stadium can be cleaned. Also, since the lifting / lowering pole is operated by the magnetic force generated by the power supply, the noise can be originally reduced, and the lifting and lowering operation can be easily performed. In addition, the upper end portion 9 of the multi-step automatic pawl may be provided with not only an illumination facility but also a necessary mechanical device such as an observing facility, if necessary.
