Description

Technical Field

[0001] The present invention relates to an auxiliary drive device for a water gate opening and closing device, a water gate opening and closing device, and an assembly method of the auxiliary drive device. Specifically, it relates to an auxiliary drive device for a water gate opening and closing device, a water gate opening and closing device, and an assembly method of the auxiliary drive device, which can be retrofitted to an existing water gate, while maintaining the necessary reduction ratio of the drive system, reducing power transmission loss, utilizing the power of a drive motor to achieve stable operation, and realizing automatic opening and closing of a door panel without modifying the drive system during retrofitting, maintaining the height position of the door panel, and operating without affecting the opening of the door panel. Background Art

[0002] For example, a small-scale sluice gate is installed in a field canal to adjust the flow of water. The sluice gate has a movable door plate, and the flow or water level can be adjusted by changing the size of the opening by lifting the door plate. It should be noted that many existing sluice gates in canals have a relatively low-cost manual drive device that manually lifts the door plate.

[0003] Although the sluice gate described above is small in scale, its gate plate is built to withstand the water pressure and is quite heavy. Therefore, if it is a manual drive device, the reduction ratio of the mechanism is increased in order to operate it with the smallest possible force. However, even if the operation is made easier, the opening and closing operation requires a lot of labor because it takes too long.

[0004] In addition, the sluice gate sometimes needs to be opened urgently, such as during heavy rain or flooding, but due to the above reasons, there is also a concern that the door panel may not be opened in time. As a countermeasure, there is a device that can automatically open and close the door panel of the sluice gate using a motor, etc. In particular, as a simple device that can be installed on the existing sluice gate, there is, for example, an "auxiliary drive device for a sluice gate opener and closeer" shown in Patent Document 1.

[0005] The auxiliary drive device of the sluice gate switch described in patent document 1 has a lifting mechanism for the door panel; the lifting mechanism includes: a spiral shaft for lifting the door panel; a worm wheel having an internal thread meshing with the spiral shaft; a worm driving the worm wheel; and a horizontal shaft driving the worm and capable of installing a manual handle.

[0006] In addition, a handle mounting unit for mounting a manual handle is provided on the first driving shaft in the gearbox; and a square hole for a rotation transmission tool with a polygonal cross section embedded in a chuck of a commercially available electric tool is provided on the second driving shaft.

[0007] In addition, a through hole is provided at a predetermined position of the gearbox, into which a horizontal rod is embedded by means of an installation mold installed on the electric tool, so as to prevent reverse rotation force when the second drive shaft is rotated in the electric tool, and by having the horizontal rod and the through hole, a retaining device is formed on the second drive shaft to maintain a normal connection state of the rotation transmission tool.

[0010] Patent Document 1: Japanese Patent Application Publication No. 2016-160650 Summary of the invention

[0011] Problem that the invention aims to solve

[0012] However, the above-mentioned conventional auxiliary drive device for the sluice gate switch has the following problems.

[0013] That is, the mechanical part that transmits the driving force of the electric motor of the electric tool to the screw shaft to make it rise and fall has the structure described as follows: first, (a) the rotational force of the horizontal shaft is transmitted to the worm wheel through the worm, and further, (b) the rotational force of the worm wheel is transmitted to the screw shaft through the engagement of the internal thread and the external thread.

[0014] In addition, a door plate as a weight is installed at the lower end of the screw shaft, and multiple reductions are performed in the gearbox. However, in the above (a), at the meshing part of the worm and the worm wheel, the gear surfaces of both sides rub against each other strongly. Furthermore, in (b), the meshing part of the internal thread of the worm wheel and the external thread of the screw shaft also rubs against each other strongly. Although lubrication is performed, a large friction force is generated in any one of them.

[0015] Therefore, for example, it is difficult to stably raise and lower a screw shaft having a heavy door panel mounted at the lower end using the power of an electric motor of a commercially available electric tool such as an impact driver as described in the specification of Patent Document 1. Even if it is possible, it is limited to use in very small sluice gates with small and light door panels.

[0016] It should be noted that, in the auxiliary drive device of the sluice gate opening and closing device including the above-mentioned Patent Document 1, there are aspects that need to be improved when the auxiliary drive device is added to the original sluice gate opening and closing device. That is, during the assembly operation of the auxiliary drive device, it is usually necessary to maintain the opening of the sluice gate plate while operating to avoid changing the flow of the water channel.

[0017] However, in the prior art, it is sometimes necessary to modify the original drive system (drive mechanism), for example, by rotating or removing the handle, etc., which causes the disadvantage that the height position of the door panel changes and the opening degree changes.

[0018] The present invention has been created in view of the above points, and its purpose is to provide an auxiliary drive device for a sluice gate opening and closing device, a sluice gate opening and closing device, and an assembly method of the auxiliary drive device, which can be retrofitted to the original sluice gate, while maintaining the necessary reduction ratio of the drive system, reducing power transmission losses, and utilizing the power of the drive motor to achieve stable operation. It can automate the opening and closing of the door panel, and there is no need to modify the drive system during installation, thereby maintaining the height position of the door panel, and being able to operate without affecting the opening of the door panel.

[0019] Means of solving the problem

[0020] (1) In order to achieve the above-mentioned purpose, the present invention is an auxiliary drive device for a water gate opening and closing device, which is an auxiliary drive device installed on the water gate opening and closing device, and the water gate opening and closing device comprises: a bearing base, which is arranged on the trunk of the water gate; a lifting shaft, which is supported by the bearing base in a manner that it can be lifted and lowered in the axial direction and the vertical direction, and a door plate is installed at the lower end; a rotating driving body is supported at a predetermined position of the bearing base in a manner that it can rotate forward and reverse, and the lifting shaft is lifted and lowered by the rotation; a handle can directly or indirectly operate the rotating driving body to perform forward and reverse rotation and reverse rotation; the auxiliary drive device comprises: a sprocket mounting plate having a predetermined split shape, which is mounted on the handle with the same rotation center when it is joined to the original shape on the joining line; a driven sprocket having a predetermined split shape, which is mounted on the sprocket mounting plate with the same rotation center when it is joined to the original shape on the joining line; a mounting table component mounted on the bearing base; a driving unit mounted on the mounting table component, and a driving sprocket is mounted on a rotating shaft driven by a driving motor; a transmission chain is wound around the driving sprocket and the driven sprocket.

[0021] In the auxiliary drive device of the sluice gate opening and closing device of the present invention, the sprocket mounting plate having a predetermined split shape and mounted on the handle with the same rotation center in a state of being joined into the original shape on the joining line can be integrated with the handle and rotate along the circumferential direction of the axis.

[0022] The driven sprocket having a predetermined split shape and mounted on the sprocket mounting plate with the same rotation center in a state of being joined to the original shape on the joining line can be integrated with the sprocket mounting plate and the handle and rotate along the circumferential direction of the shaft.

[0023] The mounting base member mounted on the bearing base serves as a base for mounting the drive unit, and can position (arrange) the drive motor included in the drive unit at a predetermined position.

[0024] The driving unit is mounted on the mounting platform component and has a driving sprocket mounted on a rotating shaft driven by a driving motor. The driving unit is located at a predetermined position capable of driving a driven sprocket, and power can be transmitted through a transmission chain. It should be noted that the rotating shaft can be the rotating shaft of the driving motor or the driven rotating shaft driven by the rotating shaft of the driving motor.

[0025] The transmission chain wound around the driving sprocket and the driven sprocket can transmit the power of the rotating shaft on which the driving sprocket is installed to the driven sprocket, and at the same time transmit it to the handle integrated with the driven sprocket to enable it to rotate.

[0026] Therefore, the auxiliary driving device of the water gate opening and closing device of the present invention can make the rotary driving body rotate forward and reverse through the rotation force of the handle, and make the door panel rise and fall together with the lifting shaft.

[0027] In addition, the drive unit transmits power between the driving sprocket and the driven sprocket via the transmission chain, so that while maintaining the reduction ratio required by the drive system, the power transmission loss can be reduced compared to, for example, power transmission based on gears. As a result, stable operation can be achieved using the power of the drive motor, and the opening and closing of the door panel can be automated.

[0028] In this way, when an auxiliary drive device is added to the original sluice opening and closing device, the sprocket mounting plate and the driven sprocket will connect the divided shape parts into the original shape. At this time, there is no need to move or disassemble the handle, or there is no need to perform new processing on the existing device, etc., and the installation work can be carried out, so the operation can be carried out in a short time.

[0029] In addition, based on this, the height position of the door panel can be maintained, and the installation work can be carried out without affecting the opening of the door panel. Therefore, the installation work is not limited to, for example, not adjusting the water volume of the channel and not affecting the period or time of the door panel opening. Therefore, it can be introduced into the original sluice opening device by retrofitting without being restricted by period or time.

[0030] It should be noted that the "divided shape" mentioned in the present invention may include not only components made by actually dividing the sprocket mounting plate and the driven sprocket that can be used directly into a plurality of parts, but also components manufactured as components equivalent to the divided shape. In addition, there is no particular limitation on the number of divisions, and in addition to being divided into two, it may be divided into three, four, or other appropriate numbers.

[0031] (2) In the auxiliary driving device of the water gate opening and closing device of the present invention, the water gate opening and closing device can be constructed as follows: the lifting shaft is supported to stop rotating along the circumferential direction of the shaft and lift, and is a spiral shaft. The rotating driving body has an internal threaded portion at the center portion. The spiral shaft is threadedly connected to the internal threaded portion at a predetermined position of the bearing base and is supported to be able to rotate forward and reversely in the horizontal direction, and the rotating shaft is lifted and lowered by this rotation.

[0032] The auxiliary drive device rotates the rotating drive body threadedly connected to the spiral shaft in the forward and reverse directions through the handle, so that the rotating shaft can be raised and lowered, and the door panel can also be raised and lowered. It should be noted that the functions and effects of the sprocket mounting plate, the driven sprocket, the mounting platform component, the driving sprocket, the driving unit and the transmission chain are the same as those described in (1) above.

[0033] (3) In the auxiliary driving device of the water gate opening and closing device of the present invention, the water gate opening and closing device can be constructed as follows: the lifting shaft is supported to stop the rotation along the circumferential direction of the shaft and lift, and is a rack shaft with meshing teeth arranged along the axial direction; the rotating driving body is supported to engage the driving teeth on the meshing teeth and can rotate in the forward and reverse directions, and the rack shaft is lifted and lowered by the rotation.

[0034] The auxiliary drive device rotates the rotating drive body with driving teeth in the forward and reverse directions through the handle, thereby raising and lowering the rack shaft with meshing teeth meshing with the driving teeth, and can also raise and lower the door panel. It should be noted that the functions and effects of the sprocket mounting plate, the driven sprocket, the mounting platform component, the driving sprocket, the driving unit and the transmission chain are the same as those described in (1) above.

[0035] (4) The auxiliary drive device of the water gate opening and closing device of the present invention may be configured such that the predetermined division in the sprocket mounting plate and the driven sprocket is divided into two parts with the diameter line as the joining line.

[0036] In this case, by dividing the sprocket mounting plate and the driven sprocket into two parts with the diameter line as the joining line, the joining line is set to a straight line, the length can be set to the minimum, and the work during the division process is easy. In addition, the joining is also easy, and the joining error is unlikely to occur at this time.

[0037] (5) The auxiliary drive device of the water gate opening and closing device of the present invention may be configured such that the joining lines of the sprocket mounting plate and the driven sprocket are installed so as to be offset from each other by a predetermined angle in the circumferential direction.

[0038] In this case, by installing the sprocket mounting plate and the driven sprocket with their joining lines staggered by a predetermined angle in the circumferential direction, the positional deviation (or correction) of the rotational center of the sprocket mounting plate and the driven sprocket can be suppressed, thereby improving the center accuracy.

[0039] Thus, the rotation accuracy of the driven sprocket has been improved, and the meshing with the transmission chain is also carried out smoothly. In addition, the engagement line of the driven sprocket is staggered by the sprocket installation plate and the driven sprocket respectively, and the intensity increases, and decomposition (separation at the same time) etc. according to the huge force of the one-time effect is also difficult to occur.

[0040] (6) The auxiliary drive device of the water gate opening and closing device of the present invention may be configured such that the joining lines of the sprocket mounting plate and the driven sprocket are offset from each other by an angle of 90° in the circumferential direction.

[0041] In this case, the joining lines of the sprocket mounting plate and the driven sprocket are offset by 90 degrees in the circumferential direction, so that one of the joining lines is located exactly in the middle of the other joining line in the circumferential direction, and the balance of resistance when force acts is better.

[0042] This can maximize the effect of (5), namely, suppressing the positional deviation of the rotation center of the sprocket mounting plate and the driven sprocket to improve the center accuracy, and increasing the strength to prevent dynamic decomposition.

[0043] (7) In order to achieve the above-mentioned purpose, the present invention is a water gate opening and closing device as described below: it comprises: a bearing base, which is arranged on the trunk of the water gate; a lifting shaft, which is supported by the bearing base in a manner that it can be lifted and lowered in the axial direction and the vertical direction, and a door plate is installed at the lower end; a rotating driving body, which is supported at a predetermined position of the bearing base in a manner that it can rotate forward and reverse, and the rotating shaft is lifted and lowered by the rotation; a handle that can directly or indirectly operate the rotating driving body to rotate forward and reverse; an auxiliary driving device; the auxiliary driving device comprises: a sprocket mounting plate having A predetermined split shape is installed on the handle with the same rotation center when it is connected to the original shape on the joining line; a driven sprocket has a predetermined split shape and is installed on the sprocket mounting plate with the same rotation center when it is connected to the original shape on the joining line; a mounting table component has a predetermined split shape and is installed on the bearing base when it is connected to the original shape; a driving unit is installed on the mounting table component, and a driving sprocket is installed on a rotating shaft driven by a driving motor; a transmission chain is wound around the driving sprocket and the driven sprocket.

[0044] By directly or indirectly operating the handle of the water gate opening and closing device of the present invention to rotate forward and reverse, the rotary driving body supported at a predetermined position of the bearing base in a manner capable of rotating forward and reverse can be rotated. The lifting shaft supported by the bearing base provided on the trunk of the water gate is lifted and lowered along the axial direction and vertical direction of the bearing base by the rotation of the rotary driving body, and the door panel installed at the lower end of the lifting shaft is also lifted and lowered.

[0045] In addition, the sprocket mounting plate having a predetermined split shape and mounted on the handle with the same rotation center in a state where the sprocket mounting plate is joined to the original shape at the joining line can be integrated with the handle and rotated in the circumferential direction of the shaft.

[0046] The driven sprocket having a predetermined split shape and mounted on the sprocket mounting plate with the same rotation center in a state of being joined to the original shape on the joining line can be integrated with the sprocket mounting plate and the handle and rotate along the circumferential direction of the shaft.

[0047] The mounting base member mounted on the bearing base serves as a base for mounting the drive unit, and can position the drive motor included in the drive unit at a predetermined position.

[0048] The drive unit is mounted on the mounting table member and has a drive sprocket mounted on a rotating shaft driven by a drive motor. The drive unit is located at a predetermined position capable of driving a driven sprocket, and power can be transmitted through a transmission chain.

[0049] The transmission chain wound around the driving sprocket and the driven sprocket can transmit the power of the rotating shaft on which the driving sprocket is installed to the driven sprocket, and at the same time transmit it to the handle integrated with the driven sprocket to enable it to rotate.

[0050] Therefore, the sluice gate opening and closing device of the present invention can make the rotary driving body rotate forward and reverse through the rotation force of the handle, and make the door panel rise and fall together with the lifting shaft.

[0051] In addition, the drive unit transmits power between the driving sprocket and the driven sprocket via the transmission chain, so that while maintaining the reduction ratio required by the drive system, the power transmission loss can be reduced compared to, for example, power transmission based on gears. As a result, stable operation can be achieved using the power of the drive motor, and the opening and closing of the door panel can be automated.

[0052] In this way, when the original sluice gate opening and closing device is retrofitted, the sprocket mounting plate and the driven sprocket will connect the split-shaped parts into the original shape. At this time, there is no need to move or disassemble the handle, or there is no need to perform new processing on the existing device, so the installation work can be carried out in a short time.

[0053] In addition, based on this, the height position of the door panel can be maintained, and the installation work can be carried out without affecting the opening of the door panel. Therefore, the installation work is not limited to, for example, the period or time when the water volume in the channel is not adjusted and the opening of the door panel is not affected. Therefore, it can be introduced into the original sluice opening device by retrofitting without being restricted by period or time.

[0054] (8) To achieve the above-mentioned object, the present invention is an assembly method of an auxiliary drive device for a water gate opening and closing device as described below, in an existing water gate including a bearing base provided on the trunk of the water gate, a lifting shaft supported by the bearing base in a manner capable of being lifted and lowered in the axial direction and in the vertical direction and having a door panel installed at the lower end, comprising the following steps: a sprocket mounting plate assembly step, in which a sprocket mounting plate having a predetermined segmented shape is joined to the handle into the original shape and is installed with the same rotation center, the handle being rotatably supported in a predetermined position of the bearing base in the forward and reverse directions; The rotation can directly or indirectly operate the lifting and lowering of the lifting shaft by rotating the rotating driving body in the forward and reverse directions; a sprocket assembly process, for the sprocket mounting plate, the driven sprocket with a predetermined segmented shape is connected into the original shape and installed with the same rotation center; a mounting table component assembly process, the mounting table component is installed on the bearing base; a transmission chain assembly process, a driving unit is installed on the mounting table component, in which a driving sprocket is installed on a rotating shaft rotated by a driving motor, and a transmission chain is wound around the driving sprocket and the driven sprocket.

[0055] According to the assembly method of the auxiliary drive device of the sluice gate opening and closing device of the present invention, first, through the sprocket mounting plate assembly process, the sprocket mounting plate with a predetermined segmented shape can be connected into the original shape, and installed on the handle with the same rotation center, and the handle can directly or indirectly operate the rotating driving body of the lifting and lowering shaft to rotate forward and reverse.

[0056] Thus, the sprocket wheel mounting plate can be integrated with the handle and rotated. In addition, the sprocket wheel mounting plate and the driven sprocket with a predetermined segmentation shape are engaged into the original shape and installed, so there is no need to rotate or disassemble the handle, that is, can be installed under the situation of the opening of the door panel without affecting it.

[0057] Then, through the sprocket assembly process, the driven sprocket with a predetermined split shape is joined into the original shape and installed on the sprocket mounting plate with the same rotation center. Thus, the driven sprocket can be integrated with the sprocket mounting plate and the handle and rotate along the circumferential direction of the shaft.

[0058] In addition, through the mounting platform component assembly process, the mounting platform component with a predetermined split shape can be joined into an original shape and mounted on the bearing base. Thus, by using the mounting platform component as a pedestal for mounting the drive unit, the drive motor of the drive unit can be located at a predetermined position.

[0059] And, according to the transmission chain assembly process, a driving unit having a driving sprocket mounted on a rotating shaft of a driving motor for rotation may be mounted on the mounting table member, and a transmission chain may be wound around the driving sprocket and the driven sprocket.

[0060] Thus, power is transmitted between the driving sprocket and the driven sprocket via the transmission chain, so that the power of the driving motor of the driving unit is transmitted to the driven sprocket and to the handle integrated with the driven sprocket, so that it can be rotated. Thus, while maintaining the reduction ratio required by the drive system, the power transmission loss can be reduced compared with the power transmission between gears, for example.

[0061] In addition, the drive unit transmits power between the driving sprocket and the driven sprocket via the transmission chain, so that while maintaining the reduction ratio required by the drive system, the power transmission loss can be reduced compared to, for example, power transmission based on gears. As a result, stable operation can be achieved using the power of the drive motor, and the opening and closing of the door panel can be automated.

[0062] In this way, when an auxiliary drive device is added to the sluice gate opening and closing device, the sprocket mounting plate and the driven sprocket will connect the divided shape parts into the original shape. At this time, there is no need to move or disassemble the handle, or there is no need to perform new processing on the existing device, so the installation work can be carried out in a short time.

[0063] In addition, based on this, the height position of the door panel can be maintained, and the installation work can be carried out without affecting the opening of the door panel. Therefore, the installation work is not limited to, for example, not adjusting the water volume of the channel and not affecting the period or time of the door panel opening. Therefore, it can be introduced into the original sluice opening device by retrofitting without being restricted by period or time.

[0064] (9) The method for assembling the auxiliary drive device of the water gate opening and closing device of the present invention may be configured as follows: the sprocket mounting plate and the driven sprocket are divided into two parts with the diameter line as the joining line.

[0065] In this case, by dividing the sprocket mounting plate and the driven sprocket into two parts with the diameter line as the joining line, the joining line is set to a straight line, the length can be set to the minimum, and the work during the division process is easy. In addition, the joining is also easy, and the joining error is unlikely to occur at this time.

[0066] (10) The method for assembling the auxiliary drive device of the water gate opening and closing device of the present invention may be configured as follows: the joining lines of the sprocket mounting plate and the driven sprocket are installed so as to be staggered at a predetermined angle in the circumferential direction.

[0067] In this case, the sprocket mounting plate and the driven sprocket are installed with their joining lines offset by a predetermined angle in the circumferential direction, thereby suppressing the positional deviation of the rotational centers of the sprocket mounting plate and the driven sprocket, thereby improving the center accuracy.

[0068] Thus, the rotation accuracy of the driven sprocket has been improved, and the meshing with the transmission chain is also carried out smoothly. In addition, the engagement line of the driven sprocket is staggered by the sprocket installation plate and the driven sprocket respectively, and the intensity increases, and decomposition etc. are also difficult to occur according to the huge force of the one-time effect.

[0069] (11) The assembly method of the auxiliary drive device of the water gate opening and closing device of the present invention can be constructed as follows: in the assembly method of the auxiliary drive device of the water gate opening and closing device, the angle between the joining lines of the sprocket mounting plate and the driven sprocket in the circumferential direction is staggered by 90°.

[0070] In this case, the joining lines of the sprocket mounting plate and the driven sprocket are offset by an angle of 90° in the circumferential direction. Therefore, one of the joining lines is located exactly in the middle of the other joining line in the circumferential direction, and the balance of resistance when force is applied is better, thereby maximizing the effect of the above-mentioned (10).

[0071] Effects of the Invention

[0072] The present invention can provide an auxiliary drive device for a sluice gate opening and closing device, a sluice gate opening and closing device, and an assembly method for the auxiliary drive device, which can be retrofitted to an existing sluice gate, while maintaining the necessary reduction ratio of the drive system, reducing the power transmission loss, and utilizing the power of the drive motor to achieve stable operation, and can realize the automation of the opening and closing of the door panel without the need to modify the drive system during retrofitting, while maintaining the height position of the door panel, and can operate without affecting the opening degree of the door panel.

[0094] First, if Figure 8 The sluice gate G shown is installed at an important position of a water channel 90, is made of concrete, and has a gate-shaped trunk 9 as a whole. A sluice gate opening and closing device G1 is installed at the center of a horizontal platform 92 of the trunk 9. The sluice gate opening and closing device G1 of the present invention is an auxiliary drive device D1 of the present invention assembled on the original sluice gate opening and closing device 8 (refer to Figure 7 ) is obtained.

[0095] The original sluice gate opening and closing device 8 (refer to Figure 1 ) has a bearing base 80 made of metal and disposed on the trunk 9. The bearing base 80 has a through hole 81 penetrating in the vertical direction and in the axial direction at the center (see Figure 4 and Figure 7 The through hole 81 has a door plate 83 mounted at the lower end thereof and a screw shaft 82 having a predetermined length slidably passes therethrough (see Figure 4 ).

[0096] It should be noted that the door plate 83 has a width substantially equal to the width of the opening 91 of the water channel 90 and moves up and down along the guide rail 96, so it does not move in the horizontal rotation direction. As a result, the screw shaft 82 does not rotate in the circumferential direction of the shaft (see Figure 8 ).

[0097] A bottomed cylindrical rotating receiving tool 84 is fixed to the upper end of the bearing base 80, and a substantially cylindrical rotating driving body 85 is arranged inside the rotating receiving tool 84 so as to be rotatable in the horizontal direction (see Figure 4 It should be noted that a threaded hole 86 is formed in the center of the rotary drive body 85 and passes through the threaded hole 86 in the axial direction. Figure 4 ).

[0098] In addition, the handle 87 is mounted on the rotary drive body 85 by means of its three spokes 870. Thus, by rotating the handle 87 in the forward and reverse directions, the rotary drive body 85 is directly rotated, and the screw shaft 82 that does not rotate in the circumferential direction of the shaft can be raised and lowered in the vertical direction together with the door plate 83 (refer to Figure 4 , Figure 8 ).

[0099] The auxiliary drive device D1 of the present invention is assembled on the above-mentioned water gate opening and closing device 8, and constitutes the water gate opening and closing device G1 of the present invention. The auxiliary drive device D1 comprises: a sprocket mounting plate 1 mounted on the above-mentioned handle 87, a driven sprocket 2 mounted on the sprocket mounting plate 1, a mounting base component 3 mounted on the above-mentioned bearing base 80, a drive unit 4 having a drive sprocket 43 mounted on the rotating shaft 42 of a drive motor 41 mounted on the mounting base component 3, and a transmission chain 5 wound around the drive sprocket 43 and the driven sprocket 2 (see Figure 7 ).

[0100] (Sprocket mounting plate 1)

[0101] The sprocket mounting plate 1 cooperates with the positioning mounting fixture 100 and is mounted on the handle 87. It should be noted that the structure of the positioning mounting fixture 100, the sprocket mounting plate 1 and the driven sprocket 2 integrally mounted to the handle 87 will be mainly referred to below. Figure 3 , Figure 4 Provide explanation.

[0102] The positioning fixture 100 has a cylindrical shaft insertion tube 101. A top plate 102 is provided at one end of the shaft insertion tube 101. The top plate 102 has a hole (reference numeral omitted) communicating with a through hole 109 of the shaft insertion tube 101. The inner diameter of the through hole 109 is formed to a size that allows the screw shaft 82 to pass therethrough.

[0103] A peripheral wall 103 is provided at the outer edge of the top plate 102, and a flange plate 104 is provided in parallel with the top plate 102. The peripheral wall 103 and the flange plate 104 are formed so that approximately one third of the circumference of the circle is missing.

[0104] The missing portion 105 is used to install the peripheral wall 103 and the flange plate 104 (see FIG. Figure 2 (a)). It should be noted that threaded holes 106 are provided through the flange plate 104 at predetermined intervals in the circumferential direction. In addition, a convex strip 107 is provided along the edge of the hole (the reference numeral is omitted) formed in the peripheral wall 103 (see Figure 3 (a)).

[0105] The sprocket mounting plate 1 is formed integrally with the positioning mounting fixture 100 and mounted on the handle 87. For convenience, Figure 3 The sprocket mounting plate 1 is shown in a joined state with the driven sprocket 2 described later, but is actually divided into two halves at a joining line 14 at a diametric position before assembly. That is, the sprocket mounting plate 1 is composed of the divided mounting plates 10a and 10b, and becomes a disc shape when joined at the joining line 14 during assembly.

[0106] The mounting plates 10a and 10b have flanges 11a and 11b, followed by peripheral walls 12a and 12b. The peripheral walls 12a and 12b are joined to form a cylindrical shape and form through holes 13. On the front end surfaces of the arc-shaped peripheral walls 12a and 12b, a convex strip 120 is provided on the hole edge side of each through hole 13.

[0107] Screw holes 122 are formed at predetermined intervals on the outer surface 121 of the convex strip 120. In addition, arc-shaped grooves 113 are formed along the edge of the through hole 13 on the flanges 11a and 11b located on the opposite sides of the peripheral walls 12a and 12b in the front and back direction.

[0108] When the mounting plates 10a and 10b are joined at the joining line 13, the convex strip 120 and the concave groove 113 become round. In addition, when the positioning mounting jig 100 is aligned with the sprocket mounting plate 1, the concave groove 113 of the sprocket mounting plate 1 is engaged with the convex strip 107 of the positioning mounting jig 100 whose rotation center is determined. Thus, the rotation center of the sprocket mounting plate 1 is also determined (see Figure 4 ).

[0109] The positioning and mounting fixture 100 and the sprocket mounting plate 1 are configured to clamp the spokes 870 of the handle 87 and are fixed and mounted by bolts and nuts (not shown) passing through the threaded holes 106 and 111. Figure 3 Although not shown in the figure, the fixing tool 15 having a recessed portion for embedding the spoke 870 is provided at three locations on the surface of the flange portion 11a, 11b having the recessed portion 113 (see Figure 2 , Figure 4 ).

[0110] (Driven sprocket 2)

[0111] The driven sprocket 2 is composed of divided gear plates 20a and 20b, which form a circle having a larger diameter than the peripheral walls 12a and 12b when joined at a joining line 24. The outer peripheral portions of the gear plates 20a and 20b are provided with teeth 200 over the entire circumference.

[0112] (Refer to Figure 2 , Figure 4 ).

[0113] In addition, the through hole 23 provided at the center of the driven sprocket 2 has an inner diameter that is rotatably fitted on the rotation receiving tool 84. This is the same as the inner diameter of the through hole 13 and the peripheral wall 103 (see Figure 2 , Figure 4 ).

[0114] The engagement side of the gear plates 20a, 20b ( Figure 3On the edge of the through hole 23 on the surface of the upper surface side (b), a groove portion 212 is provided over the entire circumference. When the driven sprocket 2 is mounted on the sprocket mounting plate 1 with the rotation center determined, the groove portion 212 is engaged with the convex strip portion 120. Thus, the rotation center of the driven sprocket 2 is also determined (see Figure 4 ).

[0115] It should be noted that when the actual sprocket (commercial standard product) is divided into two to manufacture the driven sprocket 2, it is cost-effective to select an even number of teeth close to the desired size of the sprocket. In particular, when it is divided into two, if the cut portion is cut as the tooth root, the cut object always has a symmetrical shape.

[0116] Although the tooth width of the cutter is reduced, the object to be cut (equivalent to the gear plates 20a and 20b) can be kept concentric by being engaged with the positioning portion (equivalent to the convex strip portion 120) provided on the sprocket mounting plate 1 as described above. In addition, the same is true for the driven sprockets 2a and 2b described later.

[0117] (Mounting table component 3)

[0118] The bearing base 80 and the rotating receiving tool 84 are fixed by bolting the flanges 88 and 88a (see Figure 5 ). The mounting platform component 3 first replaces the existing bolts (not shown) of the flanges 88 and 88a with long-sized bolts and nuts B1 to fix the first mounting platform component 31. Then, the connecting plate 32 is mounted on the first mounting platform component 31 using bolts and nuts B2, and further, the second mounting platform component 33 is mounted on the connecting plate 32 using bolts and nuts B3.

[0119] In this way, the first mounting base member 31 , the connecting plate 32 , and the second mounting base member 33 can be connected to their original shapes as described above, thereby forming the mounting base member 3 on which the drive unit 4 described later can be mounted.

[0120] (Drive unit 4 and transmission chain 5)

[0121] The drive unit 4 is mounted on the mounting base member 3. A drive motor 41 is housed in the housing 40 of the drive unit 4 (see Figure 6 , Figure 7 ). A driving sprocket 43 is mounted on the rotating shaft 42 of the driving motor 41. In addition, a transmission chain 5 is wound between the driving sprocket 43 and the driven sprocket 2. It should be noted that Figure 6 In the figure, for the convenience of illustration, the transmission chain 5 is shown as a belt.

[0122] Thus, the power of the driving unit 4 having the driving motor 41 can be transmitted to the handle 87 , so that the rotary driving body 85 can be rotated in the forward and reverse directions, and the door panel 83 can be raised and lowered together with the screw shaft 82 .

[0123] In addition, the number of teeth of the driving sprocket 43 is set smaller than that of the driven sprocket 2, and the power (rotational force) is transmitted at a predetermined reduction ratio through the transmission chain 5. Further, miniaturization of the driving motor 41 is achieved, and the driving unit 4 becomes compact.

[0124] It should be noted that, according to the drive unit 4, the driving sprocket 43 and the driven sprocket 2 transmit power through the transmission chain 5. Therefore, by making the number of teeth of the driven sprocket 2 greater than the number of teeth of the driving sprocket 43, the transmission loss of power can be reduced while maintaining the reduction ratio required by the drive system, for example, compared with the power transmission according to the gears. Thus, the power of the drive motor 41 can be used to achieve stable operation, and the opening and closing of the door panel 83 can be automated.

[0125] (Control mechanism of driving motor 41)

[0126] It should be noted that the drive motor 41 is a servo motor that can generate maximum torque even at 0 rpm, and is connected to a control system (not shown) to control its drive. It should be noted that the system for controlling the drive of the drive motor 41 is also connected to an absolute encoder. The absolute encoder detects the position information of the rotation in the drive motor 41 and controls the position of its rotation action.

[0127] More specifically, the drive motor 41 is driven by a control system composed of a controller and a servo driver. The controller is a command unit that outputs a command signal for an action to the servo driver. In addition, the servo driver is a control unit that outputs a pulse signal to the drive motor 41 or controls its output to follow the command signal from the controller.

[0128] In addition, the servo driver has a lower CPU and an upper CPU. The lower CPU sends a pulse signal to the drive motor 41. The lower CPU obtains the position information of the rotation position from the absolute encoder of the drive motor 41, and transmits the information of its rotation position and the judgment result of whether the position information of its rotation position is consistent with the rotation information indicated by the upper CPU to the upper CPU.

[0129] The lower CPU is configured to output a pulse signal with a pulse modulation frequency of 20 kHz. As a result, the time for outputting a pulse signal for rotating the rotating shaft is shorter than the output time of a pulse signal with a pulse modulation frequency of 10 kHz, and the rotating shaft can be driven more smoothly. As a result, the sound or vibration generated when the drive motor 41 is driven can be suppressed to a small level.

[0130] The upper CPU controls the lower CPU. The upper CPU determines the rotation speed and rotation position of the drive motor 41 and transmits them to the lower CPU as rotation information. In addition, the upper CPU is configured to be able to perform communication control from outside the drive motor 41.

[0131] The upper CPU obtains from the lower CPU the position information of the rotation position of the drive motor 41 and the information of the judgment result of whether the position information of the rotation position is consistent with the rotation information indicated by the upper CPU. Based on the information obtained from the lower CPU, when the position information of the rotation position of the drive motor 41 is inconsistent with the indicated rotation position (theoretical value position information), the upper CPU determines the correction control of the rotation.

[0132] As described above, the upper CPU is a component that controls the lower CPU that sends the pulse signal to the drive motor 41. If the position information of the rotation of the drive motor 41 is inconsistent with the rotation information indicated to the lower CPU, it has the function of correcting the rotation action of the drive motor 41 by correcting the pulse signal output from the lower CPU.

[0133] Here, in the conventional drive motor 41, since the servo driver (CPU for the driver) has only the lower CPU and does not include components corresponding to the upper CPU, the servo driver has the upper CPU as in the drive motor 41 of the present invention, and in order to make the valve actuator independent and capable of being controlled individually, an additional main control board needs to be added. If such a main control board is added, the housing or the actuator body will become larger.

[0134] Therefore, in the drive motor 41 of the present invention, the servo driver has a lower CPU and an upper CPU, which can further achieve miniaturization. In addition, in the drive motor 41 of the present invention, the servo driver is made smaller by simplifying the components included in the servo driver. As a result, the number of components included in the servo driver can be reduced and miniaturized, so that the drive motor 41 can be further reduced (the volume is about 1 / 6 compared with commercial products).

[0135] (effect)

[0136] Reference Figures 1 to 8 A method of assembling the auxiliary drive device D1 as the first embodiment of the present invention to the water gate opening and closing device G1 will be described.

[0137] As described above, the existing water gate opening and closing device 8 of the water gate G is of a type in which the handle 87 rotates in the horizontal direction and the rotation driving body 85 is directly rotated by the handle 87 .

[0138] (1) First, push the positioning fixture 100 so that the screw shaft 82 of the water gate opening and closing device 8 is embedded in the shaft insertion tube 101. At this time, the peripheral wall 103 and the flange plate 104 of the positioning fixture 100 are installed to cross two adjacent spokes 870 of the handle 87. In this way, the rotation center (center position) of the positioning fixture 100 is determined. (Refer to Figure 1 , Figure 2 )

[0139] (2) Place the mounting plates 10a and 10b of the sprocket mounting plate 1 on the inner side of the handle 87 ( Figure 2 The divided parts are joined at the joint line 14 and aligned with the positioning and mounting fixture 100, and the convex strip 107 and the concave groove 113 are fitted and installed using bolts and nuts (not shown). At this time, each fixing device 15 is embedded in each spoke 870 and firmly fixed. In this way, the rotation center of the sprocket mounting plate 1 is also determined (refer to Figure 2 ).

[0140] (3) The driven sprocket 2 formed by joining the divided gear plates 20a and 20b at the joining line 24 is fixed with bolts and nuts (not shown) by fitting the groove portion 212 into the convex strip portion 120 of the front end surface of the peripheral wall 103 of the positioning and mounting fixture 100. At this time, the joining line 14 of the sprocket mounting plate 1 and the joining line 24 of the driven sprocket 2 are fixed by being offset by 90° in the circumferential direction. At this time, one of the joining lines 14 and 24 is located in the middle of the other joining line in the circumferential direction, and the balance of resistance when force acts is better. Thus, by suppressing the offset of the rotation center position of the sprocket mounting plate 1 and the driven sprocket 2, it is possible to improve the center accuracy while determining the rotation center of the driven sprocket 2 (refer to Figure 2 , Figure 3 , Figure 4 ).

[0141] In this way, when the auxiliary drive device D1 is added to the original sluice gate opening and closing device 8, the sprocket mounting plate 1, the driven sprocket 2 and the mounting platform component 3 connect the split shape parts into the original shape. At this time, there is no need to move or disassemble the handle, or there is no need to perform new processing on the existing device, etc., and the installation work can be carried out, so the work can be completed in a short time.

[0142] In addition, based on this, the height position of the door panel 83 can be maintained, and the installation operation can be carried out without affecting the opening of the door panel 83. Therefore, the operation is not limited to, for example, the water volume of the channel 90 is not adjusted and the period or time when the opening of the door panel 83 is not affected. Therefore, it can be introduced into the original sluice opening and closing device 8 by retrofitting without being restricted by time.

[0143] (4) As described above, the mounting base member 3 is mounted on the flanges 88, 88a of the bearing base 80. (See Figure 5 )

[0144] (5) The drive unit 4 is mounted on the mounting base member 3. As a result, the heights of the drive sprocket 43 and the driven sprocket 2 become the same, so that the transmission chain 5 can be wound between the drive sprocket 43 and the driven sprocket 2. It should be noted that, usually, the winding of the transmission chain 5 is performed simultaneously with the installation of the drive unit 4 (see Figure 6 ).

[0145] (6) Install the cover 6 covering the driving sprocket 43, the driven sprocket 2 and the transmission chain 5. (See Figure 7 )

[0146] (7) In this way, an operation panel 94 is arranged on a handrail 93 provided on a platform 92 of a water gate G having a water gate opening and closing device G1 in which an auxiliary drive device D1 is assembled. Power is supplied from the operation panel 94 to the drive unit 4, so that the water gate opening and closing device G1 can be operated. In addition, a monitoring camera 95 is provided on the handrail 93 to prevent mischief (see Figure 8 ).

[0147] Next, we will refer to Figures 9 to 14 An embodiment of the auxiliary drive device D2 will be described.

[0148] Assembled auxiliary drive unit D2 (refer to Fig.14 ) of the existing sluice gate opening and closing device 8a (refer to Fig. 9 ), having a bearing base 80a made of metal provided on the trunk. The bearing base 80a is provided with a through hole 81a penetrating in the vertical direction along the axial direction and the vertical direction at the center. A door plate (not shown) is installed at the lower end of the through hole 81a, and a screw shaft 82a having a predetermined length and not rotating in the circumferential direction of the shaft can slide through it (refer to Fig. 9 ).

[0149] A large-diameter driven bevel gear (not shown) is rotatably mounted in the upper part of the bearing base 80a in the horizontal direction. The driven bevel gear is a rotating driving body having a threaded hole (not shown) in the center for the screw shaft 82a to be threadedly connected and passed through. The driven bevel gear meshes with a driving bevel gear (not shown) mounted on a horizontal rotating shaft 871 (see FIG. 1 ) of a handle 87a that rotates in the vertical direction. Fig.12 ) front end.

[0150] In addition, the handle 87a is mounted on the rotating shaft 871 by its own four spokes 870a. Thus, by rotating the handle 87a in the forward and reverse directions, the driven bevel gear is decelerated, and the screw shaft 82a that does not rotate in the circumferential direction of the shaft can be lifted and lowered in the vertical direction together with the door panel.

[0151] The auxiliary drive device D2 of the present invention is assembled on the above-mentioned water gate opening and closing device 8a, thereby forming the water gate opening and closing device G2 of the present invention. The auxiliary drive device D2 comprises: a sprocket mounting plate 1a mounted on the above-mentioned handle 87a, a driven sprocket 2a mounted on the sprocket mounting plate 1a, a mounting base component 3a mounted on the above-mentioned bearing base 80a, a drive unit 4a on which a drive sprocket 43a is mounted on the rotating shaft (not shown) of a drive motor 41a mounted on the mounting base component 3a, and a transmission chain 5a wound around the drive sprocket 43a and the driven sprocket 2a (see FIG. 1 ). Fig.14 ).

[0152] (Sprocket mounting plate 1a)

[0153] The sprocket mounting plate 1a cooperates with the positioning mounting fixture 100a and is mounted on the handle 87a. It should be noted that the structure of the positioning mounting fixture 100a, the sprocket mounting plate 1a and the driven sprocket 2a integrally mounted to the handle 87a will be mainly referred to below. Fig.11 Provide explanation.

[0154] The positioning and mounting fixture 100a has a flat cylindrical shaft insertion tube 101a. A top plate 102a is provided at one end of the shaft insertion tube 101a. The top plate 102a has a hole (reference numeral omitted) connected to the through hole 109a of the shaft insertion tube 101a. The inner diameter of the through hole 109a is formed to a size through which the rotating shaft 871 of the handle 87a passes.

[0155] On the outer edge of the top plate 102a, four protrusions 103a are provided along the circumferential direction, and between the protrusions 103a, four missing portions 105a along the diameter direction are provided at equal intervals along the circumferential direction. When mounted on the handle 87a, the missing portions 105a can be aligned with the positions of the four spokes 870a (refer to Fig. 9 (c)).

[0156] It should be noted that threaded holes 106a are provided through the top plate 102a at predetermined intervals in the circumferential direction. In addition, arc-shaped convex stripes 108a are provided on the front end surface of each protrusion 103a. The threaded holes 106a are located on the front end surface of the convex stripes 108a.

[0157] The sprocket mounting plate 1a is formed integrally with the positioning mounting fixture 100a and mounted on the handle 87a. For convenience, Fig.11The sprocket mounting plate 1a is shown in a joined state with the driven sprocket 2a described later, but in reality, it is divided into two halves at a joining line 14a at a diameter line position before assembly. That is, the sprocket mounting plate 1a is composed of the divided mounting plates 10c and 10d, and becomes a disc shape when joined at the joining line 14a during assembly.

[0158] The mounting plates 10c and 10d are joined to form a disk shape, and a through hole 13a is formed in the center. Along the hole edge of the through hole 13a on the side aligned with the above-mentioned positioning mounting fixture 100a of the mounting plates 10c and 10d, four convex strips 130 are provided at predetermined intervals along the circumferential direction. In addition, four grooves 134 are provided on the same surface side, two of which overlap with the joint line 14a.

[0159] The mounting plates 10c and 10d are provided with threaded holes 131 at predetermined intervals along the outer circumference. In addition, a step portion 132 having the same center as the through hole 13a and a diameter slightly smaller than the outer diameter is provided on the surface opposite to the surface provided with the convex strip 130 in the front-to-back direction. It should be noted that each threaded hole 131 is located outside the step portion 132.

[0160] The outer side of the convex strip 130 has a gap (reference numeral omitted), and the gap is provided with threaded holes 133 at predetermined intervals. In addition, when the positioning and mounting jig 100a and the sprocket mounting plate 1a are aligned, the front end of each protrusion 103a of the positioning and mounting jig 100a, which determines the rotation center, can be embedded in the gap. In this way, the rotation center of the sprocket mounting plate 1a is also determined (refer to Fig.12 ).

[0161] The positioning and mounting jig 100 a and the sprocket mounting plate 1 a are provided to clamp the spoke 870 a of the handle 87 a , and are fixed and mounted by bolts and nuts (not shown) penetrating the threaded holes 106 a and 133 .

[0162] (Driven sprocket 2a)

[0163] The driven sprocket 2a is composed of divided gear plates 20c and 20d, which are joined at the joining line 24a to form a circle having a diameter larger than the mounting plates 10c and 10d. The outer periphery of the gear plates 20c and 20d is provided with teeth 200 (see Fig.11 wait).

[0164] In addition, a convex strip 231 is provided over the entire circumference of the through hole 23a provided in the center of the gear plate 20c, 20d of the driven sprocket 2a on the side mounted on the sprocket mounting plate 1a. The inner diameter of the convex strip 231 having the same inner diameter as the through hole 23a is set to a size that can be externally fitted into the step portion 132 of the sprocket mounting plate 1a.

[0165] In the gear plates 20c and 20d, screw holes 232 are provided at predetermined intervals in the circumferential direction at the portions closer to the outside than the protruding strips 231. When the driven sprocket 2a is mounted on the sprocket mounting plate 1a with the rotation center determined, the protruding strips 231 are engaged with the step portions 132 of the sprocket mounting plate 1a. Thus, the rotation center of the driven sprocket 2a is also determined (see Fig.12 ).

[0166] (Mounting table component 3a)

[0167] The upper end of the bearing base 80a is fixed by tightening the base cover 880 with the existing bolts B4 (see Fig.13 First, the bolts B4 are removed and replaced with longer bolt spacers B5, and the bolt spacers B5 are passed through the bolt holes 35 to fix the mounting base member 3a (see Fig.13 ).

[0168] At this time, the bolt spacer B5 clamps the spacer (reference numeral omitted) between the base cover 880, and securely fastens and fixes the mounting platform component 3a. In addition, the L-plate-shaped mounting platform component 3a is provided with a drive unit mounting portion 34 hanging from the main body portion that is horizontal when installed. It should be noted that the mounting platform component 3a is independent and is different from the above-mentioned mounting platform component 3. It is not a component in which the divided parts are joined into the original shape.

[0169] (Drive unit 4a and transmission chain 5a)

[0170] The drive unit 4a is mounted on the drive unit mounting portion 34. The housing 40a of the drive unit 4a accommodates a drive motor 41a. The drive sprocket 43a is mounted on the rotating shaft of the drive motor 41a. A transmission chain 5a is wound between the drive sprocket 43a and the driven sprocket 2a (see Fig.14 ).

[0171] Thus, the power of the driving unit 4a having the driving motor 41a can be transmitted to the handle 87a, so that the driven bevel gear can rotate forward and reverse, and the door plate 83 can be raised and lowered together with the screw shaft 82a.

[0172] It should be noted that the number of teeth of the driving sprocket 43a is set to be less than the number of teeth of the driven sprocket 2a, and the transmission chain 5a is used to realize the transmission of power (rotational force) at a predetermined reduction ratio and the miniaturization of the drive motor 41a. The driving unit 4a becomes compact, which is the same as the above-mentioned auxiliary drive device D1.

[0173] It should be noted that, through the drive unit 4a, the driving sprocket 43a and the driven sprocket 2a transmit power through the transmission chain 5a, so that the number of teeth of the driven sprocket 2a is greater than the number of teeth of the driving sprocket 43a, while maintaining the required reduction ratio of the drive system, for example, compared with the power transmission based on the gear, the power transmission loss can be reduced. Thus, the power of the drive motor 41a can be used to achieve stable operation, and the opening and closing of the door panel 83 can be automated.

[0174] (effect)

[0175] Reference Figures 9 to 14 Next, a method (process) of assembling the auxiliary drive device D2 according to the second embodiment of the present invention to the water gate opening and closing device G2 will be described.

[0176] As described above, the conventional water gate opening and closing device 8a of the water gate is of a type in which the handle 87a is rotated in the vertical direction and the driven bevel gear is indirectly rotated by the driving bevel gear mounted on the rotating shaft 871 of the handle 87a.

[0177] (1) First, push the positioning fixture 100a in so that the rotation axis 871 of the handle 87a of the water gate opening and closing device 8a is embedded in the through hole 109a. At this time, the missing parts 105a of the positioning fixture 100a are embedded in the spokes 870a of the handle 87a. In this way, the rotation center of the positioning fixture 100a is determined (refer to Fig. 9 (c)

[0178] (2) At the inner side of the handle 87a ( Fig. 9 The mounting plates 10c and 10d of the divided sprocket mounting plate 1a are joined on the joining line 14a and aligned with the positioning mounting fixture 100a so that the convex strip portion 108a and the gap portion along the convex strip portion 130 are fitted, and the bolts and nuts B6 (see Fig. 9 ) installation. At this time, the grooves 134 of the sprocket mounting plate 1a are embedded in the inner side of the spokes 870a of the handle 87a. Thus, the rotation center of the sprocket mounting plate 1a is also determined (refer to Fig.12 ).

[0179] (3) The driven sprocket 2a formed by joining the divided gear plates 20c and 20d at the joining line 24a is fitted into the step portion 132 of the sprocket mounting plate 1a through the edge of the through hole 23a and fixed with bolts and nuts B7 (see Fig.10). At this time, the joining line 14a of the sprocket mounting plate 1a and the joining line 24a of the driven sprocket 2a are fixed by offsetting 90° in the circumferential direction. At this time, one of the joining lines 14a and 24a is located in the middle of the other joining line in the circumferential direction, and the balance of resistance when the force acts is better. Therefore, by suppressing the offset of the rotation center position of the sprocket mounting plate 1a and the driven sprocket 2a, the center accuracy can be improved while determining the rotation center of the driven sprocket 2a (refer to Fig. 9 , Fig.12 ).

[0180] In this way, when the auxiliary drive device D2 is added to the original sluice opening and closing device 8, the sprocket mounting plate 1a and the driven sprocket 2a will connect the split shape parts into the original shape. At this time, there is no need to move or disassemble the handle 87a, or there is no need to perform new processing on the existing device, etc., and the installation operation can be carried out, so the operation can be carried out in a short time.

[0181] In addition, based on this, the height position of the door panel 83 can be maintained, and the installation operation can be carried out without affecting the opening of the door panel 83. Therefore, the operation is not limited to, for example, the water volume of the water channel 90 is not adjusted and the period or time when the opening of the door panel 83 is not affected. Therefore, it can be introduced into the original sluice opening device 8 by retrofitting without being restricted by time.

[0182] (4) As described above, the mounting base member 3a is mounted on the base cover 880 of the bearing base 80a. (See Fig.13 )

[0183] (5) The drive unit 4a is mounted on the mounting base member 3a. As a result, the front and rear positions of the drive sprocket 43a and the driven sprocket 2a become the same, so that the transmission chain 5a is wound between the drive sprocket 43a and the driven sprocket 2a. It should be noted that the winding of the transmission chain 5a is also performed at the same time as the installation of the drive unit 4a, similar to the auxiliary drive device D1 described above (see Fig.14 ).

[0184] (6) Install the cover 6 that covers the driving sprocket 43a, the driven sprocket 2a, and the transmission chain 5a. In addition, a large-diameter circular plate-shaped cover plate 60 (see Fig.14 ).

[0185] (7) By doing so, the sluice gate opening and closing device G2 incorporating the auxiliary drive device D2 can be operated by supplying power to the drive unit from the operation panel provided on the platform of the sluice gate, similarly to the sluice gate opening and closing device G1.

[0186] Next, we will refer to Figures 15 to 20 An embodiment of the auxiliary drive device D3 will be described.

[0187] The existing sluice gate opening and closing device 8b (refer to Fig.15 ), having a bearing base 80b made of metal provided on the trunk. The bearing base 80b is provided with a through hole 81b penetrating in the vertical direction along the axial direction and the vertical direction at the center (refer to Fig.19 The through hole 81b has a door plate (not shown) mounted at the lower end thereof, and a rack shaft 82b having a predetermined length and not rotating in the circumferential direction of the shaft can slidably pass therethrough (see Fig.15 wait).

[0188] A rack gear 820 is formed on the rack shaft 82b, and the rack gear 820 is a tooth meshing in the length direction. In addition, a reduction unit 89 is provided on the bearing base 80b. A worm (not shown) is provided on the rotating shaft 871 inside the reduction unit 89, and a horizontal shaft (not shown) with a worm wheel (not shown) meshing with the worm installed at one end and a driving tooth (not shown) as a rotating driving body installed at the other end, and the driving tooth is meshed with the rack gear 820.

[0189] In addition, the handle 87b that rotates in the vertical direction is installed on the rotating shaft 871 through its three spokes 870b. Therefore, by rotating the handle 87b in the forward and reverse directions, the driving teeth rotate at reduced speed through the worm and the worm wheel, and the rack shaft 82b can be raised and lowered in the vertical direction together with the door panel.

[0190] The auxiliary drive device D3 of the present invention is assembled on the above-mentioned water gate opening and closing device 8b, thereby forming the water gate opening and closing device G3 of the present invention (refer to Fig. 20 The auxiliary drive device D3 comprises: a sprocket mounting plate 1b mounted on the handle 87b, a driven sprocket 2b mounted on the sprocket mounting plate 1b, a mounting base member 3b mounted on the reduction unit 89, a drive unit 4b having a drive sprocket 43b mounted on a rotating shaft (not shown) of a drive motor 41b mounted on the mounting base member 3b, and a transmission chain 5b wound around the drive sprocket 43b and the driven sprocket 2b (see FIG. Fig. 20 ).

[0191] (Sprocket mounting plate 1b)

[0192] The sprocket mounting plate 1b cooperates with the positioning mounting fixture 100b and is mounted on the handle 87b. It should be noted that the structure of the positioning mounting fixture 100b, the sprocket mounting plate 1b and the driven sprocket 2b integrally mounted to the handle 87b will be mainly referred to below. Fig.17 Provide explanation.

[0193] The positioning fixture 100b has a flat cylindrical shaft insertion tube 101b. A top plate 102b is provided at one end of the shaft insertion tube 101b, and the top plate 102b has a hole (reference numeral omitted) connected to the through hole 109b of the shaft insertion tube 101b. The inner diameter of the through hole 109b is formed to a size through which the rotating shaft 871 of the handle 87b passes.

[0194] On the outer edge of the top plate 102b, three protrusions 103b are provided along the circumferential direction, and between the protrusions 103b, three missing portions 105b are provided at equal intervals along the circumferential direction. When mounted on the handle 87b, the missing portions 105b can be aligned with the positions of the three spokes 870b (refer to Fig.15 ).

[0195] It should be noted that threaded holes 106b are formed through the top plate 102b at predetermined intervals in the circumferential direction. In addition, arc-shaped grooves 108b are formed on the front end surface of each protrusion 103b. The threaded holes 106b are located on the front end surface of the grooves 108b.

[0196] The sprocket mounting plate 1b is formed integrally with the positioning mounting fixture 100b and mounted on the handle 87b. For convenience, Fig.17 The sprocket mounting plate 1b is shown in a joined state with the driven sprocket 2b described later, but in reality, it is divided into two halves at a joining line 14b at a diameter line position before assembly. That is, the sprocket mounting plate 1b is composed of the divided mounting plates 10e and 10f, and becomes a disc shape when joined at the joining line 14b during assembly.

[0197] The mounting plates 10e and 10f are joined to form a disk shape, and a through hole 13b is formed in the center. A convex strip 136 is provided along the entire circumference of the hole edge of the through hole 13b on the side aligned with the above-mentioned positioning mounting fixture 100b of the mounting plates 10e and 10f. The front end surface of the convex strip 136 is provided with threaded holes 137 at predetermined intervals along the circumferential direction.

[0198] The mounting plates 10e and 10f are provided with threaded holes 138 at predetermined intervals along the outer circumference. In addition, a step portion 139 having the same center as the through hole 13b and a diameter slightly smaller than the outer diameter is provided on the surface opposite to the surface provided with the convex strip 136 in the front-to-back direction. It should be noted that each threaded hole 138 is located outside the step portion 139.

[0199] In addition, when the positioning fixture 100b and the sprocket mounting plate 1b are aligned, the convex strip 136 can be embedded in each groove 108b of the positioning fixture 100b determined by the rotation center. Fig.18).

[0200] The positioning fixture 100b and the sprocket mounting plate 1b are configured to clamp the spokes 870b of the handle 87b, and are fixed and mounted by bolts and nuts B8 passing through the threaded holes 106b and 137 (see Fig.15 ).

[0201] (Driven sprocket 2b)

[0202] The driven sprocket 2b is composed of divided gear plates 20e and 20f, which, when joined at the joining line 24b, form a circle having a diameter larger than the mounting plates 10e and 10f. The outer periphery of the gear plates 20e and 20f is provided with teeth 200 (see Fig.17 ).

[0203] In addition, a through hole 23b is formed at the center of the gear plates 20e and 20f of the driven sprocket 2b. The inner diameter of the through hole 23b is set to a size that can be externally fitted into the step portion 139 of the sprocket mounting plate 1b.

[0204] The gear plates 20e and 20f are provided with threaded holes 233 at predetermined intervals in the circumferential direction. When the driven sprocket 2b is mounted on the sprocket mounting plate 1b with the rotation center determined, the edge of the through hole 23b is engaged with the step portion 139 of the sprocket mounting plate 1b. Thus, the rotation center of the driven sprocket 2b is also determined (see Fig.18 ).

[0205] (Mounting table component 3b)

[0206] The reduction unit 89 is fixed by tightening the existing bolt B10 at the upper end of the bearing base 80b. First, the bolt B10 is removed and replaced with a longer bolt spacer B11, and the bolt spacer B11 is passed through the bolt hole 36 to fix the mounting base member 3b (see Fig.19 ).

[0207] At this time, the bolt spacer B11 clamps the spacer (reference numeral omitted) between the bottom of the speed reduction unit 89, and securely fastens and fixes the mounting platform component 3b. In addition, the L-plate-shaped mounting platform component 3b is provided with a drive unit mounting portion 34 hanging from the main body portion that is horizontal when installed. It should be noted that the mounting platform component 3b is independent and is not a component in which the divided parts are joined into the original shape, similar to the above-mentioned mounting platform component 3a.

[0208] (Drive unit 4b and transmission chain 5b)

[0209] The drive unit 4b is mounted on the drive unit mounting portion 34 of the mounting base member 3b. A drive motor 41b is housed in the housing 40b of the drive unit 4b. A drive sprocket 43b is mounted on the rotating shaft of the drive motor 41b. A transmission chain 5a is wound between the drive sprocket 43b and the driven sprocket 2a (see FIG. 2 ). Fig.14 ).

[0210] Thus, the power of the driving unit 4b having the driving motor 41b can be transmitted to the handle 87b, so that the driving teeth of the rotating driving body can rotate forward and reversely through the worm and the worm wheel, and the door panel and the rack shaft 82b can be raised and lowered together.

[0211] It should be noted that the number of teeth of the driving sprocket 43b is set to be less than the number of teeth of the driven sprocket 2b, and the transmission chain 5b is used to realize the transmission of power (rotational force) at a predetermined reduction ratio and the miniaturization of the drive motor 41b. The driving unit 4b becomes compact, which is the same as the above-mentioned auxiliary drive device D2.

[0212] It should be noted that, through the drive unit 4b, the driving sprocket 43b and the driven sprocket 2b transmit power through the transmission chain 5b. Therefore, by having the number of teeth of the driven sprocket 2b greater than the number of teeth of the driving sprocket 43b, the transmission loss of power can be reduced while maintaining the required reduction ratio of the drive system, for example, compared with the power transmission based on the gears. Thus, the power of the driving motor 41b can be used to achieve stable operation, and the opening and closing of the door panel can be automated.

[0213] (effect)

[0214] Reference Figures 15 to 20 Next, a method (process) of assembling the auxiliary drive device D3 according to the third embodiment of the present invention to the water gate opening and closing device G3 will be described.

[0215] As described above, the conventional water gate opening and closing device 8b of the water gate is a type in which the handle 87b rotates in the vertical direction and the rotation of the rotation shaft 871 of the handle 87b indirectly reduces the rotation speed of the driving teeth through the worm and the worm wheel.

[0216] (1) First, push the positioning fixture 100b in so that the rotation axis 871 of the handle 87b of the water gate opening and closing device 8b is embedded in the through hole 109b. At this time, the missing parts 105b of the positioning fixture 100a are embedded in the spokes 870b of the handle 87b. In this way, the rotation center of the positioning fixture 100b is determined (refer to Fig.15 ).

[0217] (2) At the inner side of the handle 87b ( Fig.15The mounting plates 10e and 10f of the divided sprocket mounting plate 1b are joined at the joining line 14b, aligned with the positioning mounting fixture 100b, and the convex strip 136 and the concave groove 108b are engaged, and then mounted with bolts and nuts B8. Thus, the rotation center of the sprocket mounting plate 1b is also determined (refer to Fig.18 ).

[0218] (3) The driven sprocket 2b formed by joining the divided gear plates 20e and 20f at the joining line 24b is fitted into the step portion 139 of the sprocket mounting plate 1b through the edge of the through hole 23a and fixed with bolts and nuts B9 (see Fig.16 At this time, the joining line 14b of the sprocket mounting plate 1b and the joining line 24b of the driven sprocket 2b are fixed while being offset by 90 degrees in the circumferential direction.

[0219] At this time, one of the joining lines 14b and 24b is located in the middle of the other joining line in the circumferential direction, and the resistance balance when the force acts is better. As a result, by suppressing the deviation of the rotation center position of the sprocket mounting plate 1b and the driven sprocket 2b, the center accuracy can be improved and the rotation center of the driven sprocket 2b can be determined (see Fig.18 ).

[0220] In this way, when the auxiliary drive device D3 is added to the original sluice gate opening and closing device 8b, the sprocket mounting plate 1b and the driven sprocket 2b will connect the divided shape parts into the original shape. At this time, there is no need to move or disassemble the handle 87b, or there is no need to perform new processing on the existing device, etc., and the installation operation can be carried out, so the operation can be carried out in a short time.

[0221] In addition, based on this, the height position of the door panel can be maintained, and the installation work can be carried out without affecting the opening of the door panel. Therefore, the operation is not limited to, for example, not adjusting the water volume of the water channel 90 and not affecting the period or time of the door panel opening. Therefore, it can be introduced into the original sluice opening device 8b by retrofitting without being restricted by time.

[0222] (4) As described above, the mounting base member 3b is mounted on the reduction unit 89 mounted on the bearing base 80b. (See Fig.19 )

[0223] (5) The drive unit 4b is mounted on the mounting base member 3b. As a result, the front and rear positions of the drive sprocket 43b and the driven sprocket 2b become the same, so that the transmission chain 5b is wound between the drive sprocket 43b and the driven sprocket 2b. It should be noted that the winding of the transmission chain 5b is also performed at the same time as the installation of the drive unit 4b, similar to the auxiliary drive device D2 described above (see Fig. 20 ).

[0224] (6) Install the cover 6 that covers the driving sprocket 43b, the driven sprocket 2b, and the transmission chain 5b. In addition, a large-diameter circular plate-shaped cover plate 60 (see Fig. 20 ).

[0225] (7) By doing so, the sluice gate opening and closing device G3 incorporating the auxiliary drive device D3 can be operated by supplying power to the drive unit from the operation panel provided on the platform of the sluice gate, similarly to the sluice gate opening and closing device G1.

[0226] The terms and expressions used in this specification and claims are for illustration only and are not intended to be limiting, nor are they intended to exclude terms and expressions that are equivalent to the features and parts thereof described in this specification and claims. In addition, it is self-evident that there may be various variations within the technical concept of the present invention.
