Description

The present invention relates to a column structure that can be raised or lowered and a railway signal light structure that employs the column structure, and more particularly, a column structure that can be raised or lowered to install a signal light, a display board, a CCTV, and the like, and a support structure thereof. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column structure capable of ascending or descending which is used as a railway signal lamp by installing a signal lamp member on an object, and a railway signal lamp structure employing the same.

It is a photograph figure which shows the form of the maintenance repair of the signal light structure for railways shown in FIG.
As shown in FIG. 16, the signal lamp member 900 is fixed to the upper end of a utility pole-shaped support structure made of a circumferential metal steel pipe. The signal light member 900 is defined to be installed about 4.2 meters above the ground with reference to the center of the lowest green color among the yellow, red, green, etc. of the signal light structure.
Accordingly, the railroad signal light structure 10 shown in FIGS. 16 to 18 has a height of about 4.5 to 5.5 meters.
Since such a signal lamp member 900 is fixed to the upper end portion of the pole-shaped column member 13, when the signal lamp member 900 breaks down, a person climbs a ladder or the like as can be seen from the photograph shown in FIG. It goes up to the table 15 and maintenance repair for repairing or replacing the signal light member 900 is performed.

However, railway signal light structures control frequent rail traffic, so prompt maintenance and repair must be performed in the event of failure. Otherwise, it may induce a rear-end collision and derailment of the train, leading to a large-scale accident.
On the other hand, since the electrification of railway lines has recently been promoted, as shown in FIG. 17, a high voltage electric wire of 25,000 volts is 4.8 to 5.2 meters in height around the railway signal light structure 10. It is installed at the height. For this reason, the minimum separation distance between the high voltage electric wire and the signal lamp structure is defined as 60 cm.
In order to repair or maintain the signal lamp member 900 installed at the upper end of the column structure 10, a person must climb the column member directly using a ladder or the like at a height where the signal lamp member 900 is installed. At this time, the height of the high-voltage electric wire and the strut structure is almost the same height, the minimum separation distance is close to about 60 cm, and the strut structure 10 is mostly made of a metal steel pipe. Therefore, an induced current may flow through the column structure 10. In particular, a considerable amount of induced current flows during low pressure or rainy weather.

When the signal light member 900 is repaired or replaced, the signal light member installed at the upper end of the column structure is raised to the height of the signal light member, and there is a risk of an electric shock accident, which may cause a fall accident due to the electric shock accident.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Embodiments of the present invention can be modified in various forms, and the scope of the present invention is not limited to the following embodiments. This embodiment is provided to more fully explain the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings is exaggerated to emphasize a clearer description.
The term “manual” used to describe the present invention refers to a power tool such as a manual or impact or electric screwdriver from outside the structure, other than simply providing power with no human power and only human power. Used as a concept that includes providing power. The concept of “automatic” is used to distinguish from the manual concept described above, and is used as a concept of providing rotational force by a power device such as a motor formed in a railway signal light structure. .

The pillar structure 1000 used to explain the present invention can be used as a railway signal lamp structure 2000 with a signal lamp member 900 attached to the upper end of the pillar. Here, the column structure 1000 according to the embodiment of the present invention can be used by attaching not only a signal lamp member but also a CCTV, a traffic information display board, and an illumination lamp. In addition, although the railway signal light structure 2000 is embodied to be used as a railway signal lamp by way of example only, it can also be used for a traffic signal lamp for a general road installed on a general road. Therefore, it can be recognized that the present invention is not limited to just a railway signal light structure.

Hereinafter, the structure of the support structure 1000 that can be raised or lowered according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 9. Next, with reference to FIGS. 1, 2, 10 and 11, a description will be given of a railway signal light structure 2000 embodied by attaching a signal light member 900 to a support structure 1000 according to the present invention. .

The currently used fixed railway signal lamp structure 10 illustrated in FIGS. 16 to 18 and described in the background art described above is installed with a signal lamp member 900 fixed to the upper end of a fixed column structure. Therefore, it can be seen that a large amount of time, number of people, expenses, etc. are required in the maintenance complement such as replacement of the signal light member 900, new installation of the column member, repair or replacement of the signal light member. In addition, in the current trend in which electric railways are gradually being expanded, the height of the column structure 10 on which the signal lamp member is installed reaches approximately 4 to 5.5 meters. On the other hand, a high-voltage electric wire through which a high voltage of 25,000 volts flows to supply power to the train is installed at a height of about 4.8 to 5.2 meters. The high voltage electric wires are arranged close to or adjacent to each other. Therefore, when the worker repairs and maintains the signal light member, the operator is exposed to the risk of electric shock and a fall due to electric shock. Therefore, the railway signal light structure that can be raised or lowered (hereinafter simply referred to as “railway signal light structure”) according to the embodiment of the present invention described in detail below is the number of people, time, and cost at the time of maintenance and repair. In addition to saving equipment purchase costs, etc., it can be seen that there is an excellent effect in terms of providing worker safety.

In addition, various strands of electric wires for supplying and controlling power to the signal lamp member 900 are installed inside the above-described support structure 1000. When wires of such various strands are installed in each strut structure, the ascending or descending operation of the strut structure causes the wires to mix or prevent the ascending or descending operation, or the wires are disconnected. Occurs. In order not to obstruct such wire breakage or ascending or descending operation, the wire must also be expanded and contracted in response to the ascending or descending operation of the column structure 1000. Therefore, the electric wire used in the railway signal lamp structure according to the embodiment of the present invention includes a spiral electric wire 950 that has a spiral shape so that a plurality of electric wires can be expanded and contracted integrally as shown in FIG. It is desirable to use it.

(Automatic lifting or lowering movement of the strut structure)
Subsequently, the automatic raising or lowering operation of the column structure 1000 will be described with reference to FIGS. 1 to 3, 13, and 14.
13 to 14 are drawings for explaining the climbing / lowering operation of the column structure 100 shown in FIG. 1, and FIG. 13 is a diagram illustrating a state in which the climbing / lowering member 800 is lowered, and FIG. It is drawing which showed the state which the boarding / lowering member 800 fell.
13 to 14, the first, second, and third support members 100, 300, and 500 are omitted in order to easily explain the ascending or descending operation of the support structure 1000 according to the embodiment of the present invention. Only the boarding / lowering member 800 will be illustrated and described.
As shown in FIGS. 13 and 14, the boarding / lowering member 800 is a generic term for the first screw member 200, the first nut member 230, the second screw member 400, the second nut member 430, the motor member 600, and the speed reducer 700. Is.
The first screw member 200 and the second screw member 400 must be threaded in different directions. In other words, if the first screw member 200 is threaded in a right-hand thread shape, the second screw member 400 is threaded in a left-hand thread shape. The opposite is also possible.

The support structure 1000 according to the embodiment of the present invention is moved up or down by the operation of the climbing member 800. If it says again, the 1st support | pillar member 100 and the 1st screw member 200 are being fixed to the base (not shown). The first nut member 230 is fastened with a bolt / nut so that it can be raised or lowered along the thread of the first screw member 200.
As shown in FIG. 13, the operation of rising to the rising state by the rotational force of the motor of the riding / lowering member 800, that is, automatically in the lowered state will be described. In FIG. 13, if the motor 600 rotates, for example, in the counterclockwise direction to raise the riding down member 800, the second screw member 400 rotates in the counterclockwise direction by the rotational force of the motor 600.
At this time, the second nut member 430 is fastened to the second screw member 400 with a nut, and ascends upward along the thread of the second screw member 400. Accordingly, since the second nut member 430 and the third support member 500 are integrally fastened, the third support member 500 is raised together by the raising operation of the second nut member 430.

At the same time, the first nut member 230 also rises upward along the thread of the first screw member 200.
This is because the first support member 100 and the first screw member 200 are fixed to the bottom surface, so that the second support member 300 and the third support member 500 are inserted into the first member 100 so as to be raised or lowered. Therefore, the second support member 200 and the third member 500 are not rotated.
Therefore, only the second screw member 400 rotates as the rotating body that rotates by the rotational force of the motor 600. The first nut member 230 formed integrally with the second support member 300 at the lower end of the second screw member 400 in response to the rotation of the second screw member 400 counterclockwise is the thread of the first screw member 200. Since the first screw member 200 and the second screw member 400 are formed in opposite directions to each other, the first screw member 200 and the second screw member 400 are lifted along the thread of the first screw member 200. . That is, it rises away from the bottom.
Simultaneously, when the second screw member 400 rotates counterclockwise, the rotation of the second nut member 430 and the third support member 500, which are bolted / nut fastened to the thread of the second screw member 400, is also limited. As a result, the second screw member 400 rises along the thread. That is, it rises away from the bottom.

Here, since the thread pitches of the first screw member 200 and the second screw member 400 are the same, the rotation of the second screw member 200 causes the first nut member 230 and the second nut member 430 to rise to the same speed. Will come to do. When the movement speed is to be changed due to the height difference between the second support member 300 and the third support member 500, the thread pitches of the first screw member 200 and the second screw member 400 are different from each other. By doing so, it can be easily understood that the moving speed of the support member can be set differently.
FIG. 14 is a view showing a state in which the boarding / lowering member 800 is raised to explain the operation of lowering the boarding / lowering member 800.
Accordingly, the lowering operation of the riding / lowering member 800 of FIG. 14 can be described as an operation in the opposite direction to the lifting operation of the riding / lowering member 800 shown in FIG. That is, as shown in FIG. 14, the rotation of the second screw member 400 rotates in the clockwise direction, so that the other lowering member 800 excluding the operation of lowering the first nut member 230 and the second nut member 430 is excluded. The operation description is the same.

(Manual lifting or lowering of the strut structure)
Subsequently, a manual ascending or descending operation of the column structure 1000 will be described with reference to FIGS. 1 to 3 and 12 to 14.
The boarding / lowering strut structure 1000 according to the present invention is manually operated as described below when the automatic climbing / lowering operation of the strut structure 1000 as described above is impossible, for example, when the rotational force cannot be provided due to a failure of the motor 600. Can be operated. Therefore, the pillar structure 1000 that can be raised or lowered automatically and manually according to the present invention is very suitable for a signal lamp pillar structure installed for a long time of about 10 to 20 years, such as a railway signal light, a traffic signal light, and an illumination light. Useful for.
Here, the manually operable climbing / lowering member 800 is illustrated in FIGS. 12 to 14, and is referred to as a manual lifting / lowering member 800, in order to distinguish it from the above-described automatically operating climbing / lowering member 800. Is a general term for the first screw member 200 (see FIG. 4), the first nut member 230 (see FIG. 5), the second screw member 400, the second nut member 430, and the manual power transmission member 650. As described above, the manual power transmission member 650 includes the first gear member 241 integrally formed on the outer side of the first nut member, the second gear 243 that rotates the first gear, the third gear 245, the fourth gear 247, And a manual power transmission shaft 250 that is fixed to the base plate and transmits a rotational force.

As shown in FIGS. 1, 2, and 12, the maintenance / repair operator may use a portable power tool such as a portable impact or a handle 610 through a rotational force providing unit 248 formed at the lower end of the support structure 1000. Provides automatic and manual rotational force through.
As shown in FIG. 13, when a rotational force is manually provided from the outside in a state where the riding / lowering member 800 is lowered, the fourth gear 247 supported by the rotational force providing unit 248 is rotated, and the first gear 247 is rotated. The third gear 245 engaged with the four gears 247 is rotated. The rotation of the third gear 245 is transmitted to the manual power transmission shaft 250 to rotate the second gear 243. The first gear 241 formed integrally with the outside of the first nut member 230 is rotated by the rotation of the second gear 243. Accordingly, the first nut member 230 is rotated by the rotation of the first gear 241.
Here, the raising or lowering operation of the first screw member 200 and the second screw member 400 due to the rotation of the first nut member 230 is the same as the above-described automatic ride-down operation.
