Description

[0001] ELEVATING LIGHTING TOWER [0002]

The present invention relates to a lifting light tower, and more particularly, to a lifting light tower capable of stably lifting and unloading a token-shaped carrier on which a plurality of lights are mounted, without shaking or falling.

The elevating light tower is disclosed in Patent Registration No. 10-1515605, which was patented and patented by the present inventor.

In the above-described lifting type illuminating tower, a ratchet extending in the longitudinal direction of the supporting stand is fixed to the upper end of the supporting stand, and a pawl is rotatably mounted on the carrier on which the illuminating tower is mounted, The pawl is caused to abut on the ratchet, and when the carrier moves in the descending direction, the pawl is hooked on the ratchet, and when the carrier rises, the detent contacts the ratchet, Wherein the carrier is provided with an electromagnet means for holding the attitude of the detent when the attitude is taken at 7 o'clock or 8 o'clock direction so that the detent can be reliably kept in the non-interrupted state, The pawl which maintains the non-pawl attitude by the pawl is moved during the downward movement of the carrier, The pawl in the non-pawl state is prevented from changing its posture due to an unintentional external force or its own weight, so that the worker can perform a work for correcting the posture error It is possible to stably position and support the illuminated carrier on the ground using a detent mounted on the carrier and a brace attached to the lower end of the support to reduce the maintenance cost of the illumination tower .

However, since the above-described lifting type lighting tower has one end of a wire fixed at the center of the carrier, the carrier can not be raised and lowered, and one end of the wire is fixed at one side of the carrier to lift and raise the carrier. 1) in a rolling contact with a plurality of pulleys through a plurality of pulleys, the carrier can not move up and down with a balancing force, which ultimately causes a problem of stability.

Further, in the above-described lifting / lowering lighting tower, since the diameter of the support table is the same as that of the supporting table, the vibration is largely generated when the carrier is lifted or lowered. In order to solve this problem, there is a problem in that the carrier has to have a smaller diameter as it goes up, but the carrier can not come into rolling contact with the landing gear at all times through the pulley.

The present invention has a problem in solving the above-mentioned problems.

The present invention is characterized in that three chord lines are fixed to a circular carrier with a phase difference of 120 degrees and the vertical line drawn on the three successive lines at the center of the carrier is fixed to each of the three lines, And the other end of the three lifting and lowering rods is fixed to a chain connected to the take-up winding portion.

In addition, the present invention is characterized in that the present invention comprises a first strut bed disposed at the lowest position and having the largest diameter, a second strut bed disposed at the highest position and having the smallest diameter, and a second strut bed disposed between the first and second strut beds, A third support bar having a diameter smaller than the diameter of the first support bar and having a diameter larger than the diameter of the second support bar is made to have a third support bar having a diameter smaller than the diameter of the first support bar and made in rolling contact with the first support bar when the carrier is positioned on the first support bar, The first spacer is placed in the first spacer in a rolling contact with the third support bar when it is located on the third support bar, and the first spacer is in rolling contact with the second spacer in the rolling contact with the second support bar when the second support bar is positioned, While the second spacer is placed on the first spacer.

According to the present invention, one end of three lifting ropes is fixed to the carrier by a phase difference of 120 degrees with respect to the carrier, so that the carrier lifts the carrier with a balancing force, So that the lamp mounted on the carrier can be prevented from being shaken at the time of ascending and descending.
