Description
The present invention relates to a hydraulic lifting gate using a hydraulic cylinder, which is convenient for maintenance, and a hydraulic cylinder is disposed at the upper end of a drainage clearance, thereby separating the hydraulic system from a river and simplifying maintenance.
Mechanical lifting of the lifting gate requires a mechanical type using a motor and a hydraulic type using a hydraulic cylinder. However, a mechanical type should be provided with a pier, a bridge, a slab, and a rail structure for installing a winch on the top of a watercraft, It is necessary to install slabs and pedestrian bridges, which are concrete structures, and foreign materials are caught in piers and slabs during floods, which interfere with water flow, cause scour and settlement problems, There is a problem that motor-driven lifting device is necessary. Hydraulic type is structurally simpler than mechanical type because it uses hydraulic cylinder, but hydraulic cylinder is installed in slab like mechanical type, built in door frame, , The method of installing the slab has the same problem as that of the mechanical type And the method of installing the hydraulic cylinder in the door frame or the hydromassage is difficult to repair due to failure of the hydraulic system and the problem of water pollution due to oil leakage can not be solved.
In this type of inflatable lifting device, the hydraulic cylinder must extend and straighten in the door frame. However, when the door lift is performed in a tilted state, the frictional resistance to the inside of the cylinder (load bearing, piston, packing) The hydraulic cylinder is inserted and attached to the door frame or the water gate and is installed in the drainage clearance. Therefore, the hydraulic cylinder is inevitably in contact with water, and the water quality is contaminated by the oil leakage. It is very difficult to repair or replace the cylinder and the door in the door frame by disassembling and removing the cylinder or the door, or by using the heavy equipment to lift the door and the cylinder as a whole.
The present invention relates to a hydraulic lifting gate which is difficult to replace or repair because it is installed in a state where the hydraulic cylinder can be brought into contact with water or is fitted inside the door frame or water gate, A hydraulic cylinder is provided on the upper side of the drainage clearance and a straight guide is provided by the cylinder guide so that even if the oil leaks, it flows into the river Do not lift.
In the present invention, a door frame to which a side of a door is inserted so as to be moved upward and downward is provided so as to move the door to the upper side of the opening and closing clearance, and a cylinder space in which a hydraulic cylinder is installed vertically is formed in the door frame, And the upper portion of the cylinder guide is coupled to a fixing bracket, the upper portion of the door frame is connected to the fixing bracket by a chain, and the oil of the hydraulic device is collected on the upper side of the opening and closing clearance An oil pan is installed in the oil pan, and a fixing device for fixing the door with the door open is provided. An opening degree detecting device for detecting the degree of opening of the door is provided on the upper side of the door frame. Shaped guide member and is guided outwardly It allows smooth movement perpendicular to install multiple.
In the door of the present invention, an emergency ring is provided at the center so that the door can be raised when the hydraulic device fails. A sedimentation prevention zone for preventing accumulation of foreign matter is provided at the lower left and right sides of the door frame.
In the present invention, maintenance of a hydraulic cylinder is performed simply by lifting a hydrologic gate with a hydraulic device, installing a hydraulic cylinder on the upper side of a drainage clearance, installing an oil pan on the upper side of a drainage clearance to prevent leakage oil from flowing into a river And the cylinder guide is inserted into the door frame for vertical movement of the hydraulic cylinder, so that the hydraulic cylinder is not operated while being bent.
The hydraulic cylinder of the present invention can be exposed to the space in a state where it is installed in the door frame, so that the maintenance can be easily performed, and even if an abnormality occurs in the hydraulic device using the fixing device installed in the oil pan, The synchronizing operation of the left and right hydraulic cylinders is performed by using the opening degree measuring device and the accumulation accumulation is prevented from accumulating on the inside of the door frame by providing a sedimentation reservoir on the floor.

The present invention relates to a hydraulic lifting sluice for lifting a door using a hydraulic cylinder, wherein a door is installed so as to open and close the opening and closing clearance by moving up and down in a state of being fitted to the door frame, The upper portion of the door frame is connected to the upper portion of the stationary bracket by a chain, and the door is lowered according to the operation of the hydraulic cylinder to block the opening and closing clearance The opening or opening of the door will open the door.
The present invention is characterized in that a hydraulic cylinder installed vertically to a door frame vertically moves the fixing bracket upward and downward while a stationary bracket is fixed to the door frame and a cylinder guide installed on the fixing bracket is fitted to the door frame so that the hydraulic cylinder can move vertically, .
Since the hydraulic cylinder of the present invention is installed inside the door frame at the top of the opening and closing clearance pipe, maintenance can be performed by simply exposing the hydraulic cylinder, and when the oil flowing from the hydraulic device to the hydraulic cylinder is leaked to the upper side of the opening- The oil pan is prevented from being contaminated by the oil, and a separate fixing device is installed in the oil pan so as to keep the door stationary even if an abnormality occurs in the hydraulic system in a state where the door is raised, The device fixes the door by projecting the fixing pin by a hydraulic cylinder.
The hydraulic cylinder and the cylinder guide of the present invention are fixed to the lower side of the fixing bracket in the vertical direction. The cylinder guide is formed of a rectangular tube. The cylinder guide is provided with a guide roller which is in close contact with the guide space of the door frame, At the same time, the hydraulic cylinder is expanded and contracted in the vertical state, so that the fixing bracket is vertically moved.
The door frame of the present invention is provided with an edge for moving the packing on the front side when the door is closed and a deposition chamber for preventing accumulation of sediment on the lower side of the door frame is provided. Accurate detection of door openings allows both hydraulic cylinders to be operated synchronously, and the opening status of the door can be remotely checked.
According to the present invention, a stationary bracket is vertically moved by a cylinder guide while a stationary bracket is vertically moved according to an operation of a hydraulic cylinder, and a door fixed to the stationary bracket by a chain is moved up and down by a stationary bracket, The emergency collar, which is installed through the fixing bracket, opens the door manually when the hydraulic device fails.
In the present invention, an oil pan is installed on the upper side of the opening and closing clearance pipe so as not to flow into the river when the oil delivered to the hydraulic cylinder leaks, and the oil pan is provided with a fixing device, So that the door does not close unless the door is released.
The present invention assures vertical movement of the hydraulic cylinder by means of the cylinder guide, and the hydraulic cylinder is installed in such a manner that it is exposed at the top of the opening and closing clearance, so there is an advantage of easy maintenance and even if oil is leaked, And accumulation of sediment is prevented by the sedimentation station provided on the left and right side of the door frame, thereby maintaining the exponential capacity.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
