In this way, the gate body 101 is prevented from directly contacting the U-shaped column, thereby reducing damage to the gate body 101 and extending the service life of the gate body 101.

[0029] When using the gate lifting device of the utility model, when the gate body 101 is half-opened or fully-opened, the hydraulic cylinder 112 is started to abut the slide plate 115 above the support seat 113 and slide between the track plates 111 until the second grinding plate 110 abuts against the first grinding plate 109, thereby limiting the rotation direction of the rotating rod 104 and preventing the rotating rod 104 from loosening during use. PLC is first used for programming so that the controller 116 can control the start and stop of the motor 105 and the hydraulic cylinder 112, thereby effectively reducing the workload of the staff, and the limit plate 117 can limit the sliding plate 115. The plate 115 moves a short distance to avoid falling off from the track plate 111, thereby reducing the subsequent maintenance cost. When the gate body 101 moves upward, it first contacts the buffer plate 118 and then squeezes the hydraulic spring 119, causing the buffer plate 118 to slide between the baffles 120. In this way, the gate body 101 is prevented from directly contacting the U-shaped column, reducing damage to the gate body 101 and extending the service life of the gate body 101. In this way, it is convenient for the staff to realize different opening angles of the gate body 101, thereby improving the practicability of the gate body 101 and reducing the workload of the staff.
