Lift gate device
The present invention provides a lift gate device with the advantages of minimum consumption of gate frame plate material, portability, reduced cost, capacity of preventing water leakage caused by damage to waterstop, and having a structure meeting the requirements of assembling and disassembling convenience of a gate device. For this reason, the lift gate device comprises: a gate frame plate which has the functions of rise-fall guide and supporting for a gate leaf and consists of a gate intercept plate and left and right back guide plate components, wherein the gate intercept plate has a discharge hole for discharging stored water to the downstream position when the gate leaf is opened, and the left and right back guide plate components are configured at two sides of the upper part of the gate intercept plate in the form of upwards extending in a 11 shape at a certain interval; a waterstop arranged around the discharge hole of the gate intercept plate; left and right side gate slot components which are vertically fixed at the left and right sides of the gate frame plate and made of a steel material; L-shaped lock components arranged at the tops of the left and right side gate slot components for preventing rising of the gate leaf; the gate leaf vertically inserted between the left and right side gate slot components for opening and closing the gate fram plate; and a gate bottom support plate horizontally arranged at the bottoms of the left and right side gate slot components.
