Hereinafter, a chain tension take-up device using gears of the sludge collector according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a chain tension take-up device for a sludge collector, and a sludge collector to which the present invention is applied includes a plurality of shafts (1) provided on a sedimentation bed (5) A chain 3 wound around the sprocket wheel 2 and a plate 4 connected to the chain 3.

At this time, any one of the plurality of shafts 1 is constituted by the moving shaft 1a which is movable in the horizontal direction.

When the moving shaft 1a is moved forward, the sprocket wheel 2a connected thereto is moved together, so that the chain 3 connected to the sprocket wheel 2a moves forward to tense the chain.

At this time, a known chain fracture detecting device 7 is installed in the sedimentation bed 5.

The present invention is largely composed of a handle 10, an adjusting shaft 20, a rotating rail shaft 30, a moving member 40 and a moving shaft fixing device 50.

As shown in FIGS. 1 and 2, the handle 10, which is a component of the present invention, is installed on the upper side of the sedimentation unit 5, and a first bevel gear 11 rotating in a vertical direction is connected to one side .

At this time, it is preferable that the first bevel gear 11 is installed inside the outer case 11a as shown in the figure.

As shown in FIG. 2, the adjusting shaft 20, which is a component of the present invention, is connected to a second bevel gear 21 which is rotated in the horizontal direction by being engaged with the first bevel gear 11 at an upper portion thereof, And a third bevel gear 22 inserted in the lower portion of the sedimentation bed 5 and rotating in the same horizontal direction as the second bevel gear 21 is connected.

The adjustment shaft 20 switches the vertical rotation of the handle 10 to the horizontal rotation as the user rotates the handle 10.

As shown in FIG. 2, the rotary rail shaft 30, which is a component of the present invention, has a first thread 31 formed on the outer peripheral surface of the intermediate portion.

And is also connected by a clamping member 32 shown inside the settling paper 5.

The rotary rail shaft 30 is connected to a fourth bevel gear 33 which meshes with the third bevel gear 22 and rotates in a vertical direction.

That is, when the fourth bevel gear 33 rotates, it is rotated together with the fourth bevel gear 33 in the axial direction.

To this end, the contact surface between the clamping member 32 and the rotary rail shaft 30 may be provided with a bearing or the like not shown.

As shown in FIGS. 2 and 3, the moving member 40, which is a component of the present invention, is provided with a through hole 41 through which the rotating rail shaft 30 penetrates inward. The through hole 41 A second thread 42 screwed with the first thread 31 is formed.

Thereby moving in the horizontal direction along the rotary rail shaft 30 when the rotary rail shaft 30 is rotated.

The moving shaft fixing device 50, which is a component of the present invention, is seated on the moving member 40 and has a moving shaft through hole 53 through which the moving shaft 1a is fastened.

That is, when the moving shaft 1a is fitted into the moving shaft through hole 53 of the moving shaft fixing device 50 connected to the moving member 40, the moving member 40 is moved in the one direction As the moving shaft 1a moves, the chain can be tensed or relaxed.

The moving shaft fixing device 50 may be constituted by various known clamping devices.

However, in the case of a conventional clamping device, when the chain 3 tends to be tilted by the operation of the handle 10, the chain 3 is broken or the chain 3 ), It becomes difficult to work because of a great deal of force.

In other words, it is necessary to clamp the chain while forcibly pulling it. In this case, even if a large number of manpower is inputted, it may happen that the chain is missed and must be re-operated.

As a method for solving such a problem, as shown in Figs. 2 and 3, the clamping device may be configured to be inclined with respect to each other.

An example of the drawing shows a case where the moving shaft fixing device 50 is provided,

The lower portion is fixed to the upper portion of the shifting member 40 and the upper portion is formed in a semicircular arc shape so that the inner circumferential surface thereof supports the lower portion of the moving shaft 1a in contact therewith, The other opposite upper end portion 51b includes a lower fixing member 51 formed to be linearly upwardly inclined from the bottom surface of the settler 5;

The lower fixing member 51 has a semi-circular arc shape so as to form a circular moving shaft through hole 53 in which the moving shaft 1a penetrates through the lower fixing member 51, And an upper fixing member 52 which is made of a resin.

In such a configuration, the moving shaft 1a, which is the axis of the sprocket wheel 2a wound with a part of the chain 3, is separated from the lower fixing member 51, The upper end of the rear portion of the fixing member 51 firmly supports the moving shaft 1a to prevent the moving shaft 1a from being separated from the inner circumferential surface of the fixing member 51. [

The first bevel gear 11 and the second bevel gear 21 are engaged with each other and the third bevel gear 22 and the fourth bevel gear 33 are engaged with each other, The direction is switched over.

This makes it possible to reduce the momentary restoring force of the tensioned chain 3 or the phenomenon that the handle 10 is loosened against the force that is returned to the original position by the loads of the chains.

In addition, by allowing the third bevel gear 22 and the fourth bevel gear 33 to be housed in the case 70, it is possible to minimize the gear components exposed in the settler 5, It is possible to reduce the occurrence of troubles or malfunctions, and the handle 10 can be operated without much effort.

In the above-described configuration, all the components may be installed in a single row in the sedimentation bed 5, but they may be arranged in two rows so as to easily prevent the moving shaft 1a from being separated, 1a) Since both sides are pulled uniformly, chain (3) is advantageous for tension.

However, when the handle 10 is manually rotated without rotating the handle 10 through the motor or the like when arranging the two rows, it is difficult to rotate the handle 10 on both sides.

As shown in FIG. 3, the rotary rail shaft 30, the moving member 40, and the moving shaft fixing device 50 have the same configuration as the moving shaft fixing device 50, and are arranged side by side in parallel to each other. The auxiliary rotating shaft 30a is connected to the auxiliary rotating shaft 30a via the auxiliary rotating shaft 30a and the auxiliary moving member 40a and the auxiliary fixing device 50a. A connecting device 60 for rotating the rail shaft 30a in the same manner as the rotating rail shaft 30 may be further provided.

The connecting device 60 may be constructed by connecting a plurality of gears, or may be constructed by directly connecting the moving member 40 and the auxiliary moving member 40a.

However, since a plurality of gear connection systems are easily disturbed by the internal sludge, it is difficult to install the sprocket wheels when connecting the moving members. As shown in the figure, 30 and the auxiliary rotating rail shaft 30a so that the two rail shafts can rotate together.

In the above-described structure, due to a load acting on a chain, sludge or the like located in the settling basin 5 or due to a reaction to return the chain to its original position by reaction immediately after take-up, The force to return the movable member 40 to its original position may act even though the force is intended to be suppressed.

This force acts because the tensioned chain 3 is relaxed, which is undesirable from the user's point of view.

As shown in FIG. 1, the case 70 includes a third bevel gear 22 and a fourth bevel gear 33 housed inwardly, and the rotating rail shaft 30 penetrates outwardly. In addition,

A cylindrical gear 80 protrudes from the outer circumferential surface of the rotary rail shaft 30 protruding outside the case 70 so as to rotate together with the rotary rail shaft 30,

And a rotary pin 90 is installed on the other end of the case 70 so as to be selectively engaged with the cylindrical gear 80 in accordance with rotation.

A stopper 100 for preventing the rotation pin 90 from rotating in one direction may be provided on the side wall surface adjacent to the rotation pin 90.

It is preferable that the stopper 100 is installed at a position for preventing the rotation of the cylindrical gear 80 corresponding to the movement of the shifting member 40 in the direction away from the fourth bevel gear 33.

This configuration is such that the tip of the rotation pin 90 is inserted between the gear teeth of the cylindrical gear 80 while being "tacked" while the handle 10 is operated, and the rotation is prevented by the stopper 90 in the opposite direction The rotation of the cylindrical gear 80 is prevented by interposing between the gear teeth, thereby preventing the rotation of the continuous bevel gears, and eventually the reverse operation of the handle 10 is prevented.

This allows the operator to prevent the handle 10 from being loosened during the middle of the operation of the handle 10 and moves to the original position in a state in which the moving shaft 1a is moved to the position designated by the operation of the handle 10. [ And is not moved.

However, when the chain 3 is to be returned to the initial state by being broken and reinstalled, it is preferable that the chain 3 can be loosened again.

6, the rotary pin 90 is connected to the case 70 by a rotary pin shaft 91 and one side of the rotary pin shaft 91 is fixed to the case 70 Hydraulic or pneumatic cylinder device, so that the tip of the rotation pin 90 can be selectively hung on the cylindrical gear 80 according to the operation of the cylinder device.

This configuration is achieved by fixing the cylinder body 91a to the case 70 and connecting the cylinder rod 91b to the rotary pin 90 to move the cylinder rod 91b from the cylinder body 91a It is possible to relax the chain 3 that has been strained by allowing the tip of the pin 90 to be selectively connected or displaced between the gears of the cylindrical gear 80 or by rotating the handle 10 in the reverse direction, (30) can be moved downward.
