Detailed Description
In order to achieve the technical means and novel features of the present invention, the purpose and function of which are easy to understand, the present invention will be further described with reference to the following detailed drawings.
As shown in fig. 1-2, a manual unlocking device for a support rod of a movable dam comprises a hydraulic cylinder groove 6, wherein a fixing bolt 5 is arranged at the bottom of the hydraulic cylinder groove 6, a hydraulic cylinder 4 is arranged in the hydraulic cylinder groove 6, a fan-shaped movable plate 2 is arranged on the hydraulic cylinder groove 6 on the upper portion of the hydraulic cylinder 4, the fan-shaped movable plate 2 is connected with the hydraulic cylinder groove 6 in a matched manner through a fixing shaft 7, a limit hook 1 is arranged on the hydraulic cylinder groove 6 on one side of the outer portion of the fan-shaped movable plate 2, and the fan-shaped movable plate 2 and the limit hook.
The sector-shaped movable plate 2 rotates around the fixed shaft 7.
The fan-shaped movable plate 2 rotates around the fixed shaft 7, and the upper surface of the fan-shaped movable plate 2 and the hydraulic cylinder groove 6 are in a plane.
The working principle is as follows:
the limiting hook 1 is fixed on one side of the top of the hydraulic cylinder groove, the fan-shaped movable plate is arranged at the top end of the hydraulic cylinder groove, one end of the fan-shaped movable plate is fixed on one side of the top end of the hydraulic cylinder groove, and the other end of the fan-shaped movable plate is arranged on the other side of the hydraulic cylinder groove. The bottom is arranged at the top end of the hydraulic cylinder, and the upper part is arranged below the cross rod of the support rod; the support rod 3 is arranged between the limiting hook and the fan-shaped movable dam, the bottom end of the hydraulic cylinder 4 is fixed at the bottom of the hydraulic cylinder groove, and the top end of the hydraulic cylinder props against the fan-shaped movable plate; the fixed bolt 5 is used for fixing the bottom of the hydraulic cylinder, and the fixed shaft 7 is used for fixing the fan-shaped movable plate so that the fan-shaped movable plate is fixedly connected with the hydraulic cylinder groove 6; the hydraulic groove 6 is fixed in the dam foundation, and the top of the hydraulic groove is level with the plane of the foundation.
In order to control the support rod to slide back and forth, two limit hooks are arranged on the inner side of the support rod and fixed on the top of the hydraulic cylinder groove; the limiting hook controls the supporting rod to slide inwards and controls the angle of the dam body; the outer side of the supporting rod is provided with a fan-shaped movable plate which controls the supporting rod to slide outwards.
