The wire ropes 5 "coming out from) are connected to the water carts through a plurality of guide rollers 6" and used to move the water carts forward and backward.

However, the types of FIGS. 1a, b, and c do take up a lot of space in the upper part of the slab or the lower part of the sedimentation basin because the conveying of the wire rope connected to the subwater cart is moved forward and backward through the drum. The length is wound around the drum, so the size and length of the drum are large, which makes it uneconomical. Also, since the wire's central axis changes with the drum's rotation, the wire rope is often pulled out of the roller or worn out. There were many defects such as deterioration.

In addition, the longer the length of the paper, the longer the length and width of the drum is relatively large due to the use of the drum, the area and volume of the device is considerably larger, and the eccentricity occurs in the movement of the shaft due to winding and unwinding the wire roller. There was a tendency to eat.

In order to solve this problem, the present invention does not require the use of bulky drums, sprockets, chains, etc., because the wire rope is operated by a traction roller assembled with a reduction motor and a single body without using a drum. And the installation space is reduced, thereby increasing the utilization space, thereby reducing the manufacturing and construction costs, and improving the sludge sedimentation efficiency of the sedimentation basin and keeping the wire rope centerline unchanged to maintain stable operation. It is an object of the present invention to provide a sludge remover driving device.

In order to achieve the above object, the sedimentation basin sludge removing device driving device according to the present invention is a device for pulling a wire rope that pulls it during the forward and backward driving of a subsea vehicle installed in the sedimentation basin by a traction roller driven by a reduction motor. An improved rotary roller is mounted on the connected shaft so as to be located inside the upper frame where the reduction motor is fixed, and a finger plate coupled with a plurality of stoppers and a sliding roller is fastened to the upper boss of the rotary roller by bolts, etc. The cam protrusion is formed in a circular shape, and the cam disc formed in the semicircular shape is fixed to the upper surface of the upper frame so as to be positioned on the finger plate, and the wire rope is wound between the winding part formed at the periphery of the rotary roller and each stopper. The stopper presses the wire rope when the sliding roller of the finger plate comes into contact with the cam protrusion of the cam disc and descends. Can allow, and becomes a sliding roller up to the stopper is out of the upper surface portion of the cam disc kaemdol is configured to move to drive the water balance by the wire rope so released.

Referring to the operation of the sludge remover driving device of the sedimentation basin according to the embodiment of the present invention as described above are as follows.

2 and 3, when the sludge settled on the bottom 10 'of the sedimentation basin 10 is scraped and transported to the discharge path 12 side, the water cart 100 is settled as shown in FIG. The power supply of the reduction motor 20 may be supplied in a state of being in proximity to the rear inner wall surface 11 of (10). In this way, the driving force of the reduction motor 20 is shifted by the reduction gear 30 and transmitted to the rotating roller 40 via the coupling 61 through the shaft 60 to rotate the rotating roller 40 forward. .

When the rotary roller 40 rotates in this way, the wire rope 5 which is in contact with the rotary roller 40 has a plurality of stoppers attached to the plurality of finger parts 76 of the finger board 70 as shown in FIG. 4A. The wire rope 5 is pressed by 71 to rotate forward together.

At this time, the plurality of sliding rollers 72 are circular cams 91 of the cam disc 90 connected to the upper frame 80 and a plurality of adjusting bolts 93 for adjusting the pressing interval as shown in FIG. 4B. The half turn is made while pressing the wire rope 5 and the other half turn just idle because there is no arc cam 91 of the cam disc 90 as shown in 4c.

In addition, when the direction of the reduction motor 20 is reverse rotation, only the direction of the wire rope 5 is reversed, the function is made as described above.

As described above, when the rotating roller 40 is rotated forward, the half of the rotating roller 40 rotates while pressing the wire rope 5, the wire rope 5 is the drawer 101 of the subsea vehicle 100 Pulling the one end and bound to enter the rotary roller 40, if the reverse rotation and the other end side bound to the back of the tow 101 enters the opposite side of the rotary roller (40).

Therefore, when the subsea vehicle 100 is towed by the wire rope 5 to move forward on the rail 7, the sludge settled at the bottom of the sedimentation basin 10 is the scraper 103 coupled to the subsea vehicle 100. It is scraped by the conveyed forward, the wire rope 5 of the input and output is guided through the take-up roller 140, and the normal vertical roller and guide rollers to pull the water cart (100).

In this operation, when the underwater truck 100 is continuously advanced and reaches the sludge discharge path 12 position, the scraper 103 is rotated by the single needle battery 10 installed at the upper side thereof to drop the sludge to the discharge path side. At this time, the reduction motor 20 is stopped at that position by the proximity switch 120 installed in the upward portion.

Next, the reduction motor 20 is reversely driven. In this case, the rotary roller 40 is reversely rotated, and this time, the other end side of the wire rope 5 is pulled forward to enter the other end of the rotary roller 40. Will rotate.

In this way, when the subsea vehicle 100 approaches the rear inner wall 11 of the sedimentation basin, the rotated scraper 103 is rotated upward by the overturning unit 110 to return to the original position, and at this time, the reduction motor 20 The wire rope 5 is reversed by the proximity switch 120 of the opposite letters connected together to be in the initial state.

Meanwhile, in this operation, the forward and backward movement and stop positions of the water truck 100 are made by the proximity switch 120, and the moving position of the water truck 100 is controlled by the controller 130 and the counter 145. The sensing signal is controlled.

That is, when the shaft 60 of the reduction motor 20 is rotated, other rollers are rotated according to the rotary roller 40. At this time, the take-up roller 140 of FIG. As the gear 142 installed on the shaft 141 on the shaft 141 and the gear 131 coupled to the side 131 of the encoder 130 rotate together with each other, the encoder 130 detects the rotational speed to generate an electrical signal. Since it is sent to the controller for numerical control of the controller by the action of the controller by the distance conversion according to the rotation of the take-up roller 140 can be monitored to move the position and position of the vehicle 100. In addition, since the counter 145 counters the moving numbers of the counter pins 144 coupled to the take-up roller 140 and sends them to the numerical controller, the counter 145 detects the normal driving situation of the subsea vehicle by the action of the controller and stops accordingly. And can be moved.

The sedimentation sludge remover driving device according to the embodiment of the present disclosure operated as described above is installed in such a way that the traction roller 50 which is engaged with the reduction motor 20 on the upper surface of the slab 13 of the sedimentation basin 10 becomes a unitary body. It is possible to smoothly transfer the wire rope 5 without using drums, and requires less installation space to secure a wider utilization space and occupy less installation space in the sedimentation basin 10. Is increased.

In addition, since the length of the wire rope 5 is shortened by the amount of windings because the facility is not wound with a drum, there is an economic advantage accordingly, and since the chain is not used, the phenomenon such as wear and corrosion can be eliminated accordingly. Since the wire rope 5 of the roller 50 is always input and output in the same trajectory as the conventional drum, the wire rope 5 always transmits power to the central axis of the other roller, unlike the conventional drum. The problem of breakage is prevented.

In addition, the direction change take-up roller 140 according to the device that performs tension in the conventional water when the tension is required by the relaxation of the wire rope 5, such as temperature conversion during long-term operation, or fatigue due to long-term driving. There is an advantage that can solve the cumbersome and uncomfortable problems caused by the problem, for example, to drain the water of the ground, and also to clean. It is a very useful design.

As described above, the sewage sludge remover driving device of the present invention has a simple configuration because it eliminates the need for using bulky drums, sprockets, chains, etc. by operating the wire rope by a traction roller assembled with a reduction motor and a single body. And the installation space is reduced, and thus the utilization space is increased. As a result, manufacturing and construction costs are reduced, as well as the effect of improving the sludge sedimentation efficiency of the sedimentation basin and the center line of the wire rope is not changed. It is a very useful design that has the effect of improving the reliability and durability of the equipment by maintaining a stable state.
