[0007] Furthermore, there are two pull rods, which are respectively arranged on both sides of the first hydraulic cylinder.

[0008] Furthermore, the number of the connecting plates is four, and the four connecting plates are symmetrically arranged on both sides of the first hydraulic cylinder, and the upper ends of the two pull rods are respectively located between the two connecting plates.

[0009] Furthermore, the connecting plate is an obtuse triangle, the obtuse angle of the connecting plate is rotatably connected to the upper end of the first hydraulic cylinder, the acute angle adjacent to the long obtuse angle side of the connecting plate is rotatably connected to the gate, and the acute angle adjacent to the short obtuse angle side of the connecting plate is rotatably connected to the upper end of the pull rod.

[0010] Furthermore, the number of the limiting members is two, and the limiting members are symmetrically arranged on both sides of the first hydraulic cylinder, and the limiting members are arranged on the outer side surfaces of the connecting plate corresponding to the outer side.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a steel dam gate lifting device with a locking mechanism comprises a base 1, a gate 2, a pull rod 3 and a first hydraulic cylinder 4 are rotatably connected to the base 1 in sequence, a connecting plate 5 is rotatably connected to the gate 2, the pull rod 3 and the first hydraulic cylinder 4 intersect in length direction and are both rotatably connected to the connecting plate 5, a limiting member 6 is installed on the gate 2, and the limiting member 6 abuts against the connecting plate 5;

[0024] The gate 2 is tilted in the direction of the first hydraulic cylinder 4 or raised in a direction away from the first hydraulic cylinder 4 by extending and retracting the first hydraulic cylinder 4;

[0025] The connecting plate 5 is abutted by the work of the limit member 6, so that the position of the connecting plate 5 is relatively fixed, reducing the load of the gate 2 on the first hydraulic cylinder 4, improving the stability of the gate 2, and effectively solving the problem of poor stability of the opening and closing equipment in the current steel dam gate 2.

[0026] The base 1 is used to be fixed on a cement base.

[0027] Specifically, there are two pull rods 3, which are respectively installed on both sides of the first hydraulic cylinder 4, and the two pull rods 3 are installed in sequence along the length direction of the gate 2;

[0028] There are four connecting plates 5, which are symmetrically located on both sides of the first hydraulic cylinder 4. Two connecting plates 5 are respectively provided on both sides of the first hydraulic cylinder 4, and the upper ends of the two pull rods 3 are respectively located between the corresponding two connecting plates 5;

[0029] The connecting plate 5 is an obtuse triangle, the obtuse angle of the connecting plate 5 is rotatably connected to the upper end of the first hydraulic cylinder 4, the acute angle adjacent to the long obtuse angle side of the connecting plate 5 is rotatably connected to the gate 2, and the acute angle adjacent to the short obtuse angle side of the connecting plate 5 is rotatably connected to the upper end of the pull rod 3. By reasonably allocating the positions of the connection points of the connecting plate 5, the gate 2, the pull rod 3 and the first hydraulic cylinder 4, the first hydraulic cylinder 4 can drive the gate 2 to rise and fall;

[0030] There are two limit members 6, which are symmetrically installed on both sides of the first hydraulic cylinder 4, and the two limit members 6 are installed corresponding to the outer side surfaces of the outer connecting plate 5 respectively; in this embodiment, the limit member 6 includes a fixed tube fixed on the gate 2 and a telescopic rod slidably connected in the fixed tube, a spring is fixedly connected between the inner end of the telescopic rod and the bottom end of the fixed tube, the outer end of the telescopic rod is hemispherical, and an abutment groove 7 is provided on the outer side surface of the outer connecting plate 5, and the abutment groove 7 is used to accommodate the outer end of the telescopic rod;

[0031] After the gate 2 is raised, the abutment groove 7 on the connecting plate 5 moves to a position corresponding to the outer end of the telescopic rod, and the outer end of the telescopic rod enters the abutment groove 7 to fix the position of the connecting plate 5, thereby reducing the load force of the gate 2 on the first hydraulic cylinder 4 and improving stability; when the gate 2 is lowered, under the combination of the squeezing force of the connecting plate 5, the spring and the shape of the outer end surface of the telescopic rod, the telescopic rod will leave the abutment groove and will not affect the lowering of the gate 2. Embodiment 2

[0032] like Figure 5 , Figure 6 and Figure 7 As shown, as another embodiment of the present application, the number of the limit members 6 is two, the limit members 6 are symmetrically located on both sides of the first hydraulic cylinder, the limit members 6 are installed on the gate 2, the limit members 6 include a second hydraulic cylinder, and an abutment groove 7 is installed on the outer surface of the outer connecting plate 5, the opening of the abutment groove 7 is upward, and the telescopic end of the limit member 6 is opened toward the abutment groove 7; the second hydraulic cylinder enters the abutment groove 7 through the telescopic movement of the second hydraulic cylinder to fix the position of the connecting plate 5, thereby reducing the load generated by the gate 2 on the first hydraulic cylinder 4. When the first hydraulic cylinder 4 fails, the second hydraulic cylinder cooperates with the pull rod 3 to keep the gate 2 in a stable state, and the gate 2 will not be opened due to the failure of the first hydraulic cylinder 4, thereby improving the stability of the gate 2 and effectively solving the problem of poor stability of the opening and closing equipment in the current steel dam gate.
