The patent CN201620624235.2 relates to a wall-through locking device for a steel dam gate, and relates to the field of hydraulic engineering, and the wall-through locking device comprises a crank arm of the steel dam gate, wherein a hydraulic power pack is connected to the crank arm, the hydraulic power pack is connected to an automatic control cabinet and a hydraulic locking oil cylinder, an oil cylinder mounting hole is arranged on the crank arm, a cylinder barrel of the hydraulic locking oil cylinder is connected to the oil cylinder mounting hole on the crank arm, a piston rod of the hydraulic locking oil cylinder is connected with a locking pin, and the locking pin extends out of the oil cylinder mounting hole of the crank arm; the side wall of the lock chamber is provided with a fixed seat, and the positioning pin is inserted in the fixed seat. However, the locking structure is troublesome in use, mainly the positioning piston rod is difficult to align to the positioning hole, and secondly, when the positioning piston rod is not aligned to the positioning hole, the positioning piston rod extends out to be propped against a positioning hole or a gate chamber wall, so that the positioning oil cylinder is easily damaged, even the swing arm is deformed and the swing arm and the bottom cross shaft connecting piece are damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, low in manufacturing cost, use simple to operate, reliable operation's a steel dam locking device.

In order to solve the problem, the utility model discloses a realize through following technical scheme: it comprises a swing arm arranged on the transverse shaft end of the inner bottom of a lock chamber, a bottom transverse shaft is fixed on a foundation through a shaft seat, a steel dam door leaf is fixed on the bottom transverse shaft outside the lock chamber, an opening and closing oil cylinder is connected on the swing arm, it is characterized in that a support rod extending to one side of the opening and closing oil cylinder is connected on the swing arm through a hinge, the support rod is placed on a support platform, a plurality of positioning blocks are arranged on a supporting platform on the side surface of the front end of the supporting rod, the positions of the positioning blocks are determined according to different opening angles of the steel dam door leaf, each positioning block is respectively connected with a piston rod of the locking oil cylinder, under the action of extension and retraction of the piston rods at different positions, the locking or unlocking of the supporting rod at the position is operated, when the piston rod pushes out the positioning block, the supporting rod is prevented from moving forwards, the locking of the supporting rod at the position is implemented, when the piston rod is retracted, the positioning block is pulled back to unlock the supporting rod, and the positioning or the positioning release of the steel dam door leaf at the position is achieved.

The number of the locking oil cylinders and the number of the positioning blocks are respectively 1-3.

According to the steel dam locking device manufactured by the scheme, the supporting rod and the positioning block controlled by the locking oil cylinder are used for controlling the steel dam door leaf at different swing angles, so that the control of the water level height is achieved. The device has simple structure, reliable and convenient locking, and avoids the problem that the positioning oil cylinder is difficult to align the positioning hole on the wall of the gate chamber and damage to the wall of the gate chamber.
