Description

Crane jig system for stop log mounting for dam sluice repair}

The present invention relates to a crane jig device used when servicing the flood gates of the dam, and more particularly, when maintaining the rear of the dam flood gate when the flood gate of the dam is broken, a relatively small force is used for heavy weights. It relates to a crane jig device for attaching and detaching the stop log for dam sluice maintenance that can be moved quickly and simply.

Dams are made by blocking rivers and valleys, trapping the water flowing through them, and using them as drinking water, agricultural water, and industrial water.

In order to properly control the amount of discharged water as needed, dams are installed, and when a flood is broken, it is difficult to maintain because the flood is under high water pressure. Turn off the product and perform maintenance.

The stop log blocks the water pressure by stacking one or several layers depending on the height of the water gate.The stop log is bulky and heavy, making it difficult to lift or lower by manpower. Lift or lower the stop log by operating the device. That is, open and close the stop log.

1 shows a state in which a conventional jig device is installed, and FIG. 2 shows moving the weight of the jig device by the attraction force, and FIGS. 3a and 3b conceptually show the jig device according to FIG. Is unlocked, and FIG. 3B is locked. Here, the release state means that the stop log is caught in the jig device, so that the stop log is not lifted when it is lifted by the crane, and the locked state is when the lift log is lifted by the crane because the stop log is not stuck to the jig device. It means the state of being raised.

As shown in Figures 3a and 3b, the opening and closing frame 110 for the stop log made of an iron frame or the like is installed on the top of the water gate.

The pillar 120 is installed at the center of the opening and closing frame 110, and is coupled by the pillar fixing shaft 130 to allow the pillar 120 to be rotated at a predetermined angle from side to side while fixing the pillar 120 to the opening and closing frame 110. That is, the pillar 120 is to rotate a certain angle to the left and right about the pillar fixed shaft 130.

Opening bar 140 is formed on one side of the pillar 120 extending to both sides, the opening and closing bar 140 is designed to vary in length depending on the rotation of the pillar 120 by a link 150 formed in the middle. .

A locking hole 160 is formed at an end of the opening and closing bar 150, and a locking protrusion 170 corresponding to the locking hole 160 is formed at the stop log L.

The top of the column 120 has a guide bar 180 is formed on the opening and closing bar, the weight bar 190 is coupled to the guide bar 180 to be moved left and right along the weight guide bar 180, weight ( 190 has handles (not shown) on both sides. The weight 190 used in the above is about 300kg in weight, and the guide bar 180 is generally coated with lubricant oil such as grease so as to reduce the frictional force when the weight 190 moves.

Referring to the operation of the conventional dam hydrology maintenance stop log detachable jig device configured as described above are as follows.

When the jig device of Figure 3a and the release device, the opening and closing bar 140 is reduced in length, the latch 160 formed at the end of the opening and closing bar 140 is separated from the locking protrusion formed in the stop log spaced apart a certain distance It is in a state. In this state, when lifting or lowering the stop log, the weight 190 positioned at the left end of the guide bar 180 should be moved to the right end of the guide bar 180.

Since the weight of the weight 190 is about 300kg, it is usually difficult to move only by one person's power, so as shown in FIG. 2, each person is attached to each side of the weight 190 by holding the handle formed on the weight 190. When pulled to the right, the weight 190 moves along the lubricated guide bar 180.

While the weight 190 is moved through the pillar 130, the center of gravity of the weight 190 is moved to the right side of the guide bar 180, wherein the pillar 120 is centered on the pillar fixing shaft 130 Opening and closing bar 140 connected to the pillar 120 while rotating at an angle to extend the length of the link 150 to the axis. As the length is increased, the locking holes 160 formed at both ends of the opening and closing bar 140 extend to the position of the locking protrusion 170 formed on the stop log, so that when the weight 190 is completely moved to the right end, the locking protrusion 170 I get caught tight. The opening and closing bar 140 is fixed to the position after adjusting the opening and closing amount of the stop log while lifting or lowering the crane (not shown) to the crane ring 115 formed in the opening and closing frame 110 in the state caught on the stop log.

If the jig device is caught in the floodgate, it may cause a safety accident due to a random operation of the crane, etc. If the weight 190 is moved to the other end by the same method again after fixing the position of the stop log, the latch 160 The position of the stop log is fixed as it is removed from the locking portion 170.

In order to lift or lower the stop log as described above, the weight bar 190 must be moved to change the opening and closing bar 140, and the opening and closing bar 140 is made in proportion to the size of the stop log, so the weight is heavy, the opening and closing bar 140 The weight 190 that can be changed is bound to be large enough to be about 300kg, it is too heavy to move the weight 190 to the manpower is difficult, the first time when moving the weight 180 of the guide bar 180 The inclination angle is large, but a lot of force is entered, but the weight weight 190 is accelerated down by gravity from passing through the center of the column 120. At this time, when the weight 190 is almost at the other end, the acceleration is the maximum, so the movement of the weight 190 is too fast, which may damage the safety of the worker moving the weight 190, in order to prevent the worker weight The work becomes more difficult because the force of the weight must be reversed to reduce the acceleration of the weight.

As described above, it is difficult to work with a lot of force at the beginning and the end to move the weight 190, and when the worker uses excessive force, the sense of balance of the human body is momentarily degraded, so that a safety accident falling from the water gate may occur. do.

In addition, when lubricating oil such as grease is applied to the guide bar 180 in order to move the weight 190 smoothly, the lubricating oil flows down and is mixed in water to cause water pollution.

The present invention is to solve the problems described above, to provide a crane jig device for detachable stop log for dam sluice maintenance that can easily and quickly move the heavy weight of the worker, and also prevent the safety accident when moving. I would like to.

The present invention is to provide a dam log maintenance jig device for dam sluice maintenance that is installed on one side of the opening and closing frame of the dam sluice in order to achieve the above object, installed on one side of the opening and closing frame pillar A pillar which is rotated by a predetermined angle around the fixed shaft; An opening and closing bar coupled to one side of the column and detachable to the stop log while its length is changed according to the rotation of the column; A rack base plate installed on the top of the pillar; A rack gear mounted to the rack base plate; A weight bundle coupled to the rack base plate and movable left and right along the rack gear; A guide roller installed opposite to the weight bundle; A pinion gear integrally formed with the weight bundle and engaged with the rack gear; A handle shaft coupled to the center of the pinion gear and extending out of the weight bundle; The handle is formed on one end of the handle shaft; provides a stop log detachable crane jig device for dam sluice maintenance comprising a.

According to the jig device according to the present invention, since the movement of the weight is made by the handle operation by the meshing of the rack gear and the pinion gear is easy to move the weight bundle is possible with only one person. In addition, safety accidents such as falling by instant fatigue due to excessive use of strength by the worker during the movement of the weight are prevented in advance, and do not cause environmental pollution problem as the jig device does not need lubricant such as grease. .

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The opening and closing frame 110 provided on one side of the stop log and the opening and closing bar 140 connected to the pillar 120 and the pillar installed in the opening and closing frame by the pillar fixing shaft 130 are the same as in the related art. Here, the pillar 120 may rotate the pillar fixing shaft 130 by a predetermined angle to the rotation axis.

As shown in FIGS. 4 and 5, a rack base plate 210 having a length of 200 cm and a width of 20 cm is formed at the top of the pillar 120, and a rack gear having a width of 10 cm at the center of the rack base plate 210. 220 is formed along the longitudinal direction of the rack base plate 210. The length and width of the rack base plate 210 and the length and width of the rack gear 220 can be designed by adding or subtracting the need.

The rack base plate 210 is inserted into the weight bundle 230 of about 300kg is coupled to move from side to side.

The pinion gear 240 is integrally formed with the weight bundle 230 while being engaged with the rack gear 220 in the weight bundle 230.

The weight bundles 230 spaced a predetermined distance from the rack gear 220 are opposed to each other, the guide roller 250 is installed. The guide roller 250 may be installed several in consideration of the load of the weight bundle (230).

The upper end of the guide roller 250 is positioned between the tooth tip and the root of the rack gear 220 so that when the pinion gear 240 is engaged with the rack gear 220, the load of the weight bundle 230 is guide roller 250 ) To be applied.

A guide roller shaft 252 is formed at the center of the guide roller 250 to be bolted with the weight bundle 230, and a bearing 254 is inserted between the guide roller 250 and the guide roller shaft 252 to guide the roller 250. ) Rotates smoothly around the guider shaft 252 without friction noise.

The handle shaft 260 is inserted and coupled to the center of the pinion gear 240 to extend outward of the weight bundle 230 and the handle 270 is coupled to the end of the handle shaft 260. The larger the diameter of the handle 270, the greater the torque can be applied to the pinion gear 240 with a small force by the lever principle, but if the width of the handle 270 is greater than 40cm in width, interference with peripheral components may occur during use. It may be desirable to be about 30cm smaller than the width of the weight bundle 230. In addition, the handle 270 may be detachable so that the handle 270 can be separated and stored as necessary.

An oilless bearing 262 is inserted between the handle shaft 260 and the weight bundle 230 through which the handle shaft 260 penetrates, thereby reducing the friction with the weight bundle 230 when the handle shaft 260 is rotated. Allow it to rotate.

Referring to the operation of the jig device according to the first embodiment of the present invention configured as described above are as follows.

When the opening and closing bar 140 to lift the stop log in the unlocked state is spaced apart from the locking protrusion 170 of the sluice, as shown in Figure 3a, the weight bundle 230 located at the left end of the rack base plate 210 Should be moved to the right end.

Holding the handle 270 and moving it to one side in order to move the weight bundle 230, torque is applied to the pinion gear 240 via the handle shaft 260, so that the pinion gear 240 is rotated to engage with the pinion gear 240. It is moved along the rack gear 220. Since the handle 270 has a width of 30 cm, a relatively large torque is applied to the handle shaft 260 by a lever principle even with a small force. Therefore, the force required to move the weight bundle 230 is relatively smaller than the existing one can be manipulated by only one person.

When the weight bundle 230 is moved by the rotation of the handle 270, the contact surface between the pinion gear 240 and the rack gear 220 may be difficult to move because friction force proportional to the weight of the weight bundle 230 is generated. On one side of the pinion gear 240, a guide roller 250 is installed, and since the weight bundle 230 load is applied to the guide roller 250, the friction force is minimized so that the weight bundle 230 is easily moved. will be.

If the worker continues to rotate the handle 270, the weight bundle 230 is moved along the rack gear 220, and when moving the center (center of the pillar) of the rack gear 220 of the weight bundle 230 The center of gravity is moved to the right around the pillar 120, the pillar 120 is rotated to the right around the pillar fixing shaft 130. At this time, the movement of the weight bundle 230 proceeds more and more rapidly by gravity. Since the rack gear and the pinion gear are engaged, the teeth are braked without slipping, and only a slight force is applied to the handle 270 in the opposite direction. Also the movement of the weight bundle 230 is easily decelerated.

When the weight bundle 230 is completely moved to the right end, the pole 120 is tilted to the maximum by the weight of the weight bundle 230, and when the pole 120 is tilted, the opening and closing bar 140 connected to the pole 120 is unfolded. While being locked, the locking hole 160 formed at the end of the opening / closing bar 140 is caught by the locking protrusion 170 of the stop log, thereby becoming a locked state as shown in FIG. 3B.

When the crane hangs up or down on the crane ring 112 formed at the top of the open frame 110 in the state where the catch 160 is caught by the catching part 170, the opening amount of the stop log is adjusted, and the opening amount of the stop log is adjusted. When the position is fixed and the weight bundle 230 to the left end of the original position so that the latch 160 is released from the locking protrusion (170).

After the stop log is operated as described above, by separating the handle 270 from the handle shaft 260 and storing it separately, a situation in which a safety accident may be prevented while manipulating the handle other than the person concerned.

Figure 6 shows a second embodiment according to the present invention, two handles 270 are installed on one side of the handle shaft 260. That is, the handle 270 uses a handle having the same size as the first embodiment, and the auxiliary handle 272 uses a handle having a smaller size than the handle 270.

The greater the width of the handle, the less force it takes to move the weight bundle 230 by the lever principle, but may be inconvenient to manipulate. Therefore, the handle 270 and the auxiliary handle 272 are installed to be selectively used according to the user's skill or individual difference.

7 is a handle 270 installed at both ends of the handle shaft 260 as a third embodiment according to the present invention. This is to make it possible to selectively operate on both sides when the handle 270 is difficult to operate only in one side of the weight bundle 230 in a particular situation.
