TECHNICAL FIELD

[0001] The utility model relates to water conservancy engineering technical field, concretely is a kind of steel dam lock bottom horizontal shaft locking device. BACKGROUND

[0002] The bottom shaft steel dam lock is the control facility of opening and closing water release channel, can be set according to river width, and simple structure.It can lock water storage, open lock flood discharge, and use lock top water in ordinary times, can form artificial waterfall landscape, and can freely adjust water retaining height, and is widely applied.

[0003] The existing bottom shaft steel dam lock is rotated by hydraulic hoist to realize water storage and water release.When needing certain water storage height, it needs to lock the bottom shaft in certain position by elbow arm.The existing locking mode has multiple, such as hydraulic locking, which directly uses hydraulic piston rod as locking latch, and hydraulic piston rod is damaged under stress, causes oil seal deformation and oil leakage, thereby affecting locking effect, and it cannot quickly realize locking task in critical moment, and flexibility is low.

[0004] Therefore, we develop and design a kind of steel dam lock four-bar linkage type locking device, in the process of opening lock and closing lock, after bottom shaft reaches required position, hydraulic piston rod pushes locking rod to complete locking, to achieve the effect of long-term positioning of door leaf. CONTENT OF UTILITY MODEL

[0005] The utility model aims at providing a kind of steel dam lock bottom horizontal shaft locking device to solve the problems raised in the above background.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] A kind of steel dam lock bottom horizontal shaft locking device, including bottom horizontal shaft, fixedly arranged with elbow arm on bottom horizontal shaft, fixedly arranged with locking rainbow on the top of bottom horizontal shaft, elbow arm is covered outside locking rainbow and can rotate along locking rainbow, multiple L-shaped locking slots are formed in the bottom of locking rainbow, the locking rod below locking rainbow is hinged to the inside one end of elbow arm, locking oil cylinder is rotatably arranged on the side of elbow arm, the lower end of locking rod is hinged to the output end of locking oil cylinder, and the end of locking rod can be clamped in L-shaped locking slot.

[0008] As a further preferred scheme of the utility model: the locking rod base below locking rainbow is fixedly arranged on the inside of elbow arm, and the locking rod is hinged to the locking rod base.

[0009] As a further preferred scheme of the utility model: the oil cylinder base is arranged on the front side of elbow arm, and the locking oil cylinder is rotatably arranged on the oil cylinder base.

[0010] Compared with prior art, the utility model has the beneficial effects that:

[0011] The bottom horizontal shaft locking device is locked by cooperation of the locking oil cylinder and the locking rod, when the locking oil cylinder piston rod extends, the locking rod is pushed to rotate, when the end of the locking rod reaches the L-shaped locking slot on the locking rainbow, the locking is completed, at this time the force borne by the steel dam lock is borne by the locking rod, the piston rod does not bear additional force, thereby the sealing system of the locking oil cylinder is protected, the locking failure is prevented, the structure design is scientific and reasonable, the structure is simple, disassembly, maintenance and practicality are convenient.

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0017] Embodiment 1

[0018] Please refer to Figures 1-3. This embodiment provides a locking device for the bottom horizontal axis of a steel dam gate, including a bottom horizontal axis 3. A crank arm 4 is fixedly installed on the bottom horizontal axis 3, and a locking rainbow bridge 2 is fixedly installed above the bottom horizontal axis 3. Specifically, as a conventional design, rainbow bridge bases 1 should be set on both sides of the bottom horizontal axis 3 so that the locking rainbow bridge 2 is installed on the rainbow bridge base 1. The crank arm 4 covers the outside of the locking rainbow bridge 2 and can rotate along the locking rainbow bridge 2. Multiple L-shaped locking grooves 5 are opened at the bottom of the locking rainbow bridge 2. The number of L-shaped locking grooves 5 can be evenly arranged according to actual needs, which will not be described in detail in this application. A locking rod 7 corresponding to the L-shaped locking groove 5 is hinged to one end of the inner side of the crank arm 4 and located below the locking rainbow bridge 2. Specifically, a locking rod base 6 located below the locking rainbow bridge 2 is fixedly installed on the inner side of the crank arm 4, and the locking rod 7 is hinged to the locking rod base 6. A locking cylinder 8 is rotatably mounted on one side of the crank arm 4.
