Description
The present invention relates to a method for lifting a lifting jacket using a mechanical or hydraulic lifting device, which is improved by a weight variable type, and is capable of varying the starting weight of a door to open and close without using a lifting device, So as to be able to be opened and closed by a small amount of power even when it is opened and closed.
It is necessary to change the rating of the motor and winch or hydraulic cylinder to open / close the door in proportion to the weight of the door, and to change the weight of the door The more wind turbines are needed, the more power is needed.
In case of lifting the door by using mechanical or hydraulic hoisting device, since the hoisting device having a large rated capacity of the motor or the hydraulic cylinder can not be used in proportion to the weight of the door, the manufacturing cost of the hoisting device is increased, It takes a long time to lift, and it is mechanically burdened to reduce durability and service life.
There is a method of using a weight to reduce the lifting load of the door. However, the method using the weight can open and close the door with a small power, but it is difficult to open and close the door without using the lifting device When weights are used, the force acts to lower the weight of the door at all times. Therefore, the watertightness becomes a problem when the door is closed.
The present invention relates to a salvage gate. Even when a weight is used to use low power for lifting a door, the weight of the door is always lowered by the weight of the weight while the lifting device is used. This is to solve the problem that the watertightness can not be completely achieved when closing the door with the problem of opening and closing the door only if it is equipped with it. In case of opening the door, the weight of the weight is increased. By lowering the weight of the door, it is possible to open and close the door without using the lifting device, and when the door is closed, the watertight can be done only by the weight of the door.
The present invention provides a door frame which is inserted into a door frame and which is vertically movable. The chain gears are installed on both sides of the door frame so that the chain fixed on both sides of the door frame is extended over the chain gear. And an auxiliary tank for filling the antifreezing liquid is installed on the upper side of the drainage clearance, and the auxiliary tank is installed in the auxiliary tank and the variable tank, When the door openings are opened by moving the doors upward, the antifreeze of the auxiliary tank is moved to the variable tank so that the door can be heard. When the door is moved downward, Move the antifreeze of the tank to the auxiliary tank so that it is closed by the door's own load. do.
A buffer spring is installed on the travel guide of the present invention so as to prevent a shock when the heavy object moves, and a leakage preventing fan for receiving the antifreeze of the variable tank and the auxiliary tank when they leak, Allow the antifreeze to move with the pump.
The present invention can be used in addition to a hoisting device for opening and closing the door. In this case, the rated capacity of the motor or the hydraulic cylinder for driving the hoisting device can be greatly reduced.
The present invention relates to a door opening and closing apparatus for opening and closing a door of a lifting door, which can open the door even when a small amount of energy is used by using a heavy article which can support the weight of the door. When the weight of the heavy article is increased, It is possible to open and close the door without using a mechanical or hydraulic hoisting device. Even when the hoisting device is used, the opening and closing of the door can be easily performed even if the capacity of the motor or the hydraulic cylinder is greatly reduced .

The present invention relates to a door opening / closing mechanism for opening and closing a door frame by moving up and down door frames inserted in a door frame, wherein the doors are easily lifted by using heavy materials, It uses a power lifting device to open the door and to close the door by weight.
The present invention is characterized in that a chain fixed on both sides of a door frame is laid over a chain gear installed on both sides of the door frame and then fixed to the chain at the rear of the door frame so that the door is opened when the heavy object is heavy and the door is closed when the object is light The chain gears of the present invention are provided horizontally on both sides of the upper portion of the door frame. The heavy gears are composed of fixed weight portions fixed in weight and variable tanks varying in weight. The variable tanks are filled with auxiliary tanks So that the antifreeze can be filled by driving the pump.
The heavy weight of the present invention is characterized in that a variable tank is provided above a fixed weight portion, and a doctor bearing or a running pipe is installed on the edge of the plate supporting the heavy weight, And the door is connected by a chain, which is connected to the chain gear.
Buffer springs are provided on the upper and lower sides of the travel guide so that even when a heavy object hits the up-and-down movement, it can be buffered.
The auxiliary tank is installed at the rear of the heavy object, and the pump is installed to move the auxiliary liquid filled in the auxiliary tank and the variable tank. A valve for selecting the movement of the antifreezing liquid is provided between the auxiliary tank and the variable tank. , An auxiliary pump and a manual pump should be installed to prevent malfunction in case of emergency.
In the present invention, when the antifreeze filled in the auxiliary tank is moved to the variable tank by the pump, the weight of the heavy material becomes heavy. When the weight of the heavy material is excessively large, the heavy material falls and the chain is pulled. Therefore, the door is lifted without using a lifting device to raise the door. Even when the lifting device is used, the door is lifted by using a small capacity motor or a hydraulic cylinder.
When the door is opened, the pump is operated to move the antifreezing liquid filled in the variable tank to the auxiliary tank. As a result, the weight of the heavy object is lightened, and the door is easily closed by its own weight.
The present invention can change the weight of a heavy object so that even when a door is opened or closed without using a lifting device or when a lifting device is used, the door can be easily opened even if a motor or a hydraulic cylinder having a rated capacity is used. And the watertightness can be ensured by self-weight. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
