The present invention relates to the improvement of hydraulic doubly gates used for river level adjustment, and is a hydraulic type that makes it possible to reduce the drop in the riverbed caused by the installation of the gate, and to facilitate the rejection and maintenance of the gate. It relates to a douging gate.

The inventors of the present invention devised a hydraulic dobok gate shown in Figs. 3 and 4 and discloses it as a laboratory 50-24029.

In other words, the hydraulic lattice gate is loosely swept up and down by lowering the lower edge of the door D to all of the jizan frames B provided at the appropriate intervals on the bottom wall A of the waterway. In addition, the piston rod G end of the hydraulic cylinder F is mounted on the rear upper part of the electric door D by the rod axis axis H, and the bottom end of the hydraulic cylinder F is mounted on the rear part of the electric support frame B by the mounting arm I. Each of them is pivotally mounted by J, and the opening and closing of the door D is performed by stretching the piston rod G.

Electro-hydraulic doppler gate is simple in structure and small-capacity hydraulic cylinder that can open and close the door lightly and has excellent practical utility. However, many problems remain to be solved in the hydraulic doubly gate.

The first problem is the problem of free fall caused by the installation of the gate. As shown in Fig. 3, in this type of hydraulic dodging gate, the hydraulic cylinder F is stored at the back side of the door D when the door D is rolled, so a drop H 'is inevitably required between the upper and lower lower and lower streams. do.

This is because when a vortex for storing the hydraulic cylinder F is formed in the lower part by digging only the rear side of the door D, the soil flows backward and gradually accumulates in the vortex, so that the door can not be opened and closed smoothly.

Therefore, in order to obtain the constant gate popularity F ', the hydraulic cylinder F must be mounted so that the hydraulic cylinder F is inclined by an angle a with respect to the horizontal direction in order to obtain a constant gate popularity F'. In addition, laboratory 50-24029 Since the lower end of the hydraulic cylinder F is held by the axis J to rotate the lower end of the cylinder with a larger diameter, the height L of the axis J must be larger than 1/2 of the outer diameter of the cylinder. Needed. As a result, in a stream with a gentle flow gradient, the riverbed downstream has to be excavated over a long distance, and along this, the river bank is also increased, resulting in a rise in civil engineering cost.

The second problem is that it takes time and manpower to repair and reject gates.

In the past, such a hydraulic lattice gate was used to excavate the lower end of the cylinder to the bottom wall A, and to bury all hydraulic-related piping in the water channel concrete bottom wall, raise it from the bottom wall A near the hydraulic cylinder F, and connect it to the cylinder F by a flexible pipe or the like. The method of doing so is generally performed (laboratories 50-24029, laboratories 40-21405, etc.).

However, when the hydraulic pipe is buried in the concrete wall A of the water channel, manpower is required for repairing the hydraulic pipe and it takes time, and only the hydraulic pipe must be constructed separately in order to reject the gate, and shorten the air and reduce the labor. Can't try.

The third problem is the problem of simplicity such as rejection of the gate.

In laboratory No. 50-24029, the structure of disposing a dripping arm C on the whole and the descent frame B having the dripping arm I on the rear side in parallel on the channel bottom wall A at regular intervals, and holding the door D on it. As a result of this, there is a problem that it takes time and attraction to the extraction of the jizan frame B and it is difficult to increase the degree of rejection of the gate.

The invention devises the same problems as those described above in the conventional hydraulic lattice gate, i.e. requiring a large downfall H '. 2) Time and manpower for maintenance and construction of the hydraulic piping and 3) rejection of the gate. It is to provide a hydraulic doppler gate that solves the problems such as increase of air handling and difficulty of rejection, and enables reduction of river drop, construction and repair of hydraulic piping, and simplification of gate rejection.

That is, the structure of the present invention is mounted on all of the plurality of support frames and the electric support frame, which are arranged at the appropriate transverse intervals on the channel bottom wall, and the transverse restraints having mounted mounting brackets at the appropriate transverse intervals. Iii) and; A flat plate-shaped gate in which the lower edge is extracted as relief material by the gate extraction to each of the electric rackets, and further, the racket is installed on the upper rear side; A single-cylinder hydraulic cylinder in which the cylinder body is rotatably pushed by the cylinder shaft on the electric bracket; When the end of the piston rod is fixedly pivoted by the piston rod axis, fixed to the rear part of the supporting frame, and the piston rod axis is the electric cylinder axis when the electric gate stands up at a predetermined maximum relief angle. Between the vertical line passing through the center of the shaft and the electric gate axis, and the support for supporting the electric piston rod axis at a position where the axis of the piston rod is inclined upward by an angle a when the electric gate is fully inclined; ; The main body of the cylinder is secured to the back side of the electric gate and connected to the hydraulic operator by opening the swivel joint disposed coaxially with the electric gate axis, and opening the swivel joint disposed coaxially with the electric cylinder axis. The hydraulic piping connected to the main structure is to be designed.

Therefore, in the present invention, when the piston rod is extended by the operation of the hydraulic cylinder when the gate is in the doped state, the reaction force F acts on the cylinder axis 9, and the pulling force of F '= F sin a acts on the gate. As a result, the gate is pulled upward with the gate axis as a point, and is supported on the rear surface side by the hydraulic cylinder in the extended state.

Next, upon releasing the support by the hydraulic cylinder, the gate sequentially rolls over and degenerates into the piston rod. When the gate is inclined to the weakly horizontal state, the hydraulic cylinder is accommodated on the rear side of the gate with the inclination angle a maintained in the horizontal direction.

Hereinafter, based on the accompanying drawings showing an embodiment of the present invention as follows.

FIG. 1 is a longitudinal side view of the hydraulic dosing gate according to the present invention, and FIG. 2 is a rear view of the hydraulic dosing gate (however, the left half is not shown from the downstream side). In the figure, 1 is a channel side wall, 2 is channel concrete bottom wall, 3 is a support frame formed by combining channel steel, etc., and is embedded and fixed in the electric channel concrete bottom wall 2. 4 is a lateral anchor made of H-shaped steel or the like, and is mounted on the upper portion of the electric support frame 3 (upstream of the upstream side). 5 is a plurality of rackets screwed to the trailing edge side (downstream side) of the electric transverse restraint 4 at an appropriate lateral spacing, and the lower edge of the gate 6 is connected to the sun attaching racket 5 by the gate axis ( 7) are plunged freely.

Above the rear side of the electric gate 6, the sub-racquets 6a are fixed to each other at appropriate lateral intervals, and both centering racks 6a coincide with the center line of the electric support frame 3. As far as possible. 8 is a hydraulic cylinder of a single cylinder type, and the center part of the cylinder main body 8b is rotatably pulled to the electric racket 6a by the cylinder axis 9 by opening the trunnion ring 8a. . In addition, the tip of the piston rod 10 of the single-cylinder hydraulic cylinder 8 is pivotally screwed to the mounting rod 11 fixed to the rear side of the electric support frame 3 by the piston rod pivot 12. .

In pivoting the tip of the electric piston rod 10 to the mounting bracket 11 freely, when the gate 6 stands up completely at a predetermined maximum elevation angle (typically 60 ° to 70 °), the piston rod When the center of the axis 12 is located between the vertical line passing through the center of the cylinder axis 9 and the gate axis 7, and when the electric gate 6 is completely inclined, the axis of the piston rod 10 is in the horizontal direction. The mounting position of the electric mounting bracket 11 is determined to have a constant inclination angle a.

In addition, the position of the water column for extracting the cylinder body on the upper rear side of the gate 6 and the position on the hydraulic cylinder axis line of the sea stem shaft 9 can be appropriately determined without being restricted to the illustrated embodiment. . 13 is a hydraulic pipe fixed to the back surface side of the electric gate 6, and is a so-called pararell-like circuit for synchronizing and interlocking the operation of several hydraulic cylinders 8. In addition, in the figure, 13a is a hydraulic pipe which is installed in the channel side wall 1, and communicates with hydraulic operators, such as a hydraulic pump and a hydraulic tank, not shown, 14a is a swivel joint coaxially arranged with the gate axis 7; 14b is a swivel joint disposed coaxially with the cylinder axis 9, and 15 is located on the site of the hydraulic pipe 13, which is fixed to the rear side of the gate in advance, and the hydraulic pipe 13a embedded in the waterway concrete bottom wall 2, and the like. In each case, the collection point is shown.

In addition, the present invention is not limited to the above-described embodiments, and if necessary, various design changes and modifications can be made within the scope of the gist such as, for example, double acting hydraulic cylinder or multi-coated gate. It can be done easily.

One embodiment of the present invention is constructed as described above, in order to undulate the gate 6 as desired, the pressure supply or discharge of the pressure oil to each of the hydraulic cylinders 8 is changed to the direction change valve ( The piston rod 10 may be stretched or retracted by controlling by the operation of (not shown).

That is, for example, in Fig. 1, the pressure oil is applied to the upper chamber (right side of the piston not shown in the drawing) of the hydraulic cylinder 8 (normally may be single-acting) in the fully doped state indicated by the dashed-dotted line. When the piston rod 10 is stretched in the hydraulic cylinder 8 by supplying the oil, in this case, since the loads acting on each of the hydraulic cylinders 8 are substantially all equal, the distributed hydraulic pressure is equal to each hydraulic cylinder. This expansion is performed extremely synchronously from the introduction of the same speed and flow rate in (8), and the force F acts on the axial center direction A of the hydraulic cylinder 8 starting from the center of the piston rod axis 12. Then, the gate popularity of F '= F sin a acts on the gate 6, and the upper part of the gate 6 which was in the doped state is pushed up, and the gate 6 is centered on the gate axis 7. It rotates and stands up counterclockwise between the two channel side walls 1, and leads to a complete closure of the sea channel at a predetermined angle.

However, while the gate 6 is pushed up and rotated, the reaction force R acts on the piston rod 10, and the reaction force R is stopped by the support frame 3 embedded in the channel concrete bottom wall 2 and stopped. 6, the piston rod 10 is rotated up extremely smoothly with the extension of the piston rod (10).

The three points of the gate axis 7, the piston rod axis 12, and the cylinder axis 9 constitute a triangular type of trust structure, and include the gate 6, the transverse restraint 4, and the support frame ( 3), the hydraulic cylinder 8 and the piston rod 10 share the load or cooperate with each other to support each other to exhibit sufficient strength. As a result, even if a load by a large hydraulic pressure acts on the gate 6, it is not broken and damaged, and it can endure long-term use.

In addition, since the hydraulic latching gate 6 according to the present invention has a structure in which the piston rod 10 of the hydraulic cylinder 8 is directly pushed up and rotated, it is more frictional than the type having a link or the like. The loss is small, and thus the hydraulic cylinder 8, which is relatively small and small in capacity, can also rotate the gate 6 lightly.

As described above, according to the present invention, the cylinder body 8b of the single-cylinder hydraulic cylinder 8 is mounted on the gate 6 side, and the tip of the piston rod 10 is mounted on the support frame 3, that is, a relatively outer diameter. When the inclined angle a is the same when this small piston rod 10 side is crushed to the support frame 3, compared with the case where the large diameter cylinder main body 8b side is crushed to the support frame 3, The fall of the riverbed can be reduced by that much. In other words, the downfall of the upstream side and the downstream side of the gate 6, even if it is very small, does not interfere, and it is impossible even to install the hydraulic docking gate of the other method for the conventional publicly known, or even in the point where it is under extremely difficult environment and conditions. Not only can there be almost no restraint or technical obstacles, but the construction can be carried out, and the hydraulic piping work can be made simpler and easier. In addition, when the falling of the lower phase between the same upstream and downstream is allowed, the inclination angle a of a cylinder can be set large at the time of gate expansion, and the larger gate popularity F 'can be obtained. Further, the cylinder body 8b of the hydraulic cylinder 8 is mounted on the upper rear side of the gate 6, and the tip of the piston rod 10 is mounted on the support frame 3 side, respectively, and both swivel joints ( Since 14a and 14b are arranged on the coaxial line with the gate axis 7 and the cylinder axis, the hydraulic pipe 13 is mounted on the rear side of the gate 6, and the hydraulic drive source and the cylinder body ( 8b) can be contacted easily so that they can rotate.

As a result, maintenance, inspection, and maintenance of the hydraulic cylinder and hydraulic piping system can be performed extremely easily, and repair and replacement in the event of failure or damage of the hydraulic cylinder and the hydraulic piping system can be performed very easily, resulting in a significant reduction in maintenance costs. . In addition, the supporting frame (3), the transverse restraint (4), the gate (6), the hydraulic cylinder (8) and the piston rod (10), and the required hydraulic piping and direction change variations are all integrally mounted in the factory. After assembling as one set, the gate can be shipped in the form of a complete product by performing a no-load opening / closing test or the like, and the work efficiency is greatly improved at the rejection site.

Then, the plurality of support frames 3 are buried and fixed in the concrete bottom wall 2 of the waterway at an appropriate lateral spacing, and the one transverse material 4 is transversely placed on the support frame 3, and the transverse material 4 Since the lower end of the gate 6 is squeezed out by attaching the mounting bracket 5 to the cuff), even if there is some error in the buried fixation of the support frame 3, The shaft center of the gate axis 7 is not disturbed at all, and compared with the case where the gate is directly drilled on the support frame 3 without using the transverse material 4 as in the laboratory 50-24029, It is effective to reduce or increase the degree of rejection.
