Description

TECHNICAL FIELD [0001] The present invention relates to a screw shaft support frame stabilizer for a waterway system for a public road,

.

[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw shaft movable support frame stabilizer of a hydrologic apparatus for a public road.

The public road located near the river or the sea is equipped with a hydrological device to prevent the seawater or the river from invading the city area due to a tidal wave or abnormal storm. The movable support frames 6 and 6a and 6b having rollers and wheels are seated on a rail embedded in the bottom of the concrete housing 1 and the movable support frames 6 and 6a 6b, screw shaft holders 7 are assembled with bolts and nuts.

The movable support frames 6, 6a, 6b are connected by a chain, the leftmost movable support frame 6 and the concrete housing 1 are connected by a chain, and the rightmost movable support frame The screw shaft 3 is provided between the drive unit 2 provided on the concrete housing 1 and the nut 5 fixed to the water gate 4, 1, the left end of the screw shaft 3 is fastened to the drive unit 2, and the screw shaft 3 passes through the screw shaft holder 7 described above. In the meantime, the chain described in the drawings of the present invention is not shown.

1, when the driving device 2 is operated and the screw shaft 3 is rotated, the nut 5 is assembled to the water gate 4, so that the water gate 4 is moved to the right side in the drawing of FIG. At this time, the movable support frames 6b (6a) and 6 (6) sequentially move along the water gate.

However, since the screw shaft 3 having a length of about 5 meters or more and 10 meters or so usually has to swing vertically and horizontally when rotating, the screw shaft holder 7 holds the screw shaft 3 as shown in the drawing The movable support frame described above is also shaken back and forth and all directions by the impact force of the screw shaft 3 causing the roller support of the movable support frame to deviate from the rail.

If the movable support frame described above is deviated from the rail, the rotary motion of the screw shaft 3 is greatly affected, and further, the parts of the screw shaft holder 7 are damaged, Resulting in an uneconomical shutdown that requires frequent maintenance and replacement of parts.

In the prior art relating to the present invention relating to the present invention, firstly, when the patent registration No. 10-1470452 is considered, a sluice gate is located outside the concrete housing and a complicated sluice gate driving device is used to open and close a hole in the concrete housing The present invention is different from the present invention in that it is different from the present invention because there is no structure and explanation as compared with the screw shaft movable support frame stabilizer of the present invention.

Next, in the case of the publication No. 10-2011-0097538, a hydraulically operated hydromotor driving apparatus having a structure similar to that of the above-mentioned Patent Registration No. 10-1470452 is used to open and close a hydrological gate by using a hydraulic cylinder or a drum winch and a wire In addition, since there is no structure and explanation to be compared with the screw shaft movable support frame stabilizer of the present invention, it is judged that this technique is different from the present invention.

In addition, Patent Registration No. 10-0344058, Patent Registration No. 10-0994358, 0923635. 1139511, 1209244, and the like, all of which relate to a device for opening and closing a water channel by using a vertically operated gate (hydrologic gate), which is also incompatible with the screw shaft movable support frame stabilizer of the present invention, Are considered to be different distinct technologies.

[Technical Problem]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a screw shaft movable support frame stabilizing device of a hydrologic apparatus for a public road which can solve both problems and problems caused by the conventional technology.

[Structure and operation of the invention]

The present invention for solving the above-mentioned problems is constituted as follows.

Two sets of fasteners 10 fixed to the left and right sides of the top of the movable support frame 6b (6a, 6) with bolts 11 toward the inner wall surface of the concrete housing 1;

Two sets of reinforcing bars (12) fixed to the fixture (10) at an angle of 45 ° and fixed by welding are fixed by welding while maintaining an angle of 45 ° to the reinforcing bars (12) Two pairs of support rods 13 formed with holes 13a through which the rotor 17 passes;

A pair of brackets 15 each having a hole 15a through which the support rod 13 passes and a slot 16 through which the support rod fixing pin 17 is linearly moved;

Two pairs of coil springs 14 fitted to the support rods 13 to elastically support the bracket 15;

A pair of support bar fixing pins 17 whose positions are fixed by a snap ring 17a while passing through the slot 16 of the bracket 15 and the hole 13a of the support bar 13;

A wheel fixing pin 19 fixed to the left and right sides of the bracket 15 with a snap ring 19a;

A pair of urethane wheels 18 fixed to the left and right sides of the bracket 15 assembled to the wheel fixing pin 19a and having a ball bearing therein;

And two pair of angle rails 20 fixed horizontally to the inner wall surface of the concrete housing 1 through the embedding bolts to guide the linear movement of the urethane wheel 18. [

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

The present invention is characterized in that a fixture 10 is fixed to the left and right sides of a movable support frame 6b (6a, 6) and an inner wall surface of a concrete housing 1 via bolts 11 as shown in Figs. 1 and 2, The urethane wheels 18 are held in contact with the angle rails 20 fixed horizontally on the left and right sides of the inner wall surface of the housing 1 as shown in Fig.

In this state, the screw shaft 3 is rotated by the operation of the drive unit 2, so that the water gate 4 starts to move toward the highway (from the state of FIG. 1 to the right side) The movable support frame 6b in the vicinity moves first in the moving direction of the gate 4 and then the movable support frame 6a in the middle moves and finally the movable support frame 6 in the leftmost position starts to move The urethane wheel 18 moves on the angle rail 20.

In this process, the screw shaft 3 passes through the inside of the screw shaft holder 7 fixed to the upper surface of the movable support frame. However, the screw shaft 3 having a longer length moves from the moment it starts rotating And the rotational force is converted into an impact so that the screw shaft holder 7 and the movable support frame described above are impacted.

As described above, since the impact generated from the screw shaft 3 does not point in a specific direction but acts in all directions, the movable support frame starts shaking from the screw shaft holder 7, The rollers assembled below the movable support frame derail the rail.

Even if the movable support frame is shaken up or down and tilted upward or tilted toward the inner wall surface of the concrete housing 1 as described above, the reinforcement member 12 and the support bar 13 can not move The coil spring 14 disperses the above-mentioned impact and at the same time, the resilient force of the coil spring 14 pushes the fixture 12 back to the above-mentioned movable support frame Therefore, the rollers of the above-described movable support frame can always maintain their positions without derailment of the rail.

The support rod fixing pin 17 fixed to the support rod 13 moves up along the elongated hole 16 of the bracket 15 when the support rod 13 is moved by the above action, The urethane wheel 18 is kept in a state of being in tight contact with the angle rail 20 without being separated from the angle rail 20 at all times.

It is a matter of course that the operation of the present invention as described above is equally applied to the case where the water gate 4 is back into the concrete housing 1 again.

In the present invention, when the movable support frame is moved along with the water gate, even when the impact force generated when the screw shaft is swung in all directions is transmitted to the movable support frame, the impact force is absorbed and dispersed, There is a great effect of preventing the derailment, and thus the linear movement motion of the watercraft can be performed very smoothly and stably.
