Abstract
The utility model discloses a safety locking device for gates. The safety locking device for gates comprises a support arm (2) fixed to a gate shaft (5), a hydraulic cylinder (3) arranged on the support arm and parallel to the gate shaft (5), and a hydraulic pump (4) arranged on the support arm, wherein the hydraulic cylinder is connected with the hydraulic pump through a hydraulic oil pipe, and a plurality of locking holes (6) are formed on a fixed wall body, matched with the hydraulic cylinder (3), and uniformly distributed on the wall body by taking the gate shaft (5) as an axis. By adopting the technical scheme, the safety locking device for gates can lock the gates at any angle, and is convenient for operation; and by adopting the hydraulic cylinder and the hydraulic pump, the device has certain buffer effect, reduces the abrasion of equipment and has long service life.
Description
Technical field
The utility model relates to the water conservancy gate, relates in particular to a kind of gate safe locking device.
Background technology
The water conservancy gate is an equipment indispensable in the water resources and hydropower construction.In the use of gate, the holding in a certain permanent position of gate at this time just need be able to be used the locking device of gate for the effect of making waterfall for the size of controlled water flow or view gate.The pure frame for movement that present gate adopts just can lock need aim at latched position in the locking that pounds the door after, inconvenient operation, and pure frame for movement, and wear block, the life-span is short.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of gate safe locking device that can arbitrarily angled locking gate is provided, and this device is easy to operate, and the life-span is long.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of gate safe locking device, comprise and the fixing support arm of gate axle, be arranged on the hydraulic cylinder parallel on the support arm with the gate axle, be arranged on the hydraulic pump on the support arm, be connected by hydraulic oil pipe between hydraulic cylinder and the hydraulic pump, the some keyholes that cooperate with hydraulic cylinder are set on fixing body of wall, and described some keyholes are to serve as spool to be distributed on the body of wall with the gate axle.
The fixing push rod in the end of hydraulic cylinder.
Described keyhole is the conical blind hole that has certain taper, and the end of described push rod is provided with the taper seat end that cooperates with keyhole circular cone blind hole.
Described hydraulic pump is the hydraulic pump of manual and electric one.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, the gate safe locking device inserts keyhole by the hydraulic pump drive hydraulic cylinder, realizes the locking of gate, utilizes hydraulic means any again angle to start the gate safe locking device, and is easy to operate, wearing and tearing are little, the life-span is long;
2, the fixing push rod in the end of hydraulic cylinder, the diameter of push rod greater than hydraulic cylinder diameter, improved the anti-shearing force of gate safe locking device, the application life of having improved this device;
3, keyhole is the conical blind hole that has certain taper, and the end of push rod is provided with the taper seat end that cooperates with keyhole circular cone blind hole, is convenient to extracting out from keyhole of push rod, and it is loosening to need not the gate answer, can unblank, and the damping force of unblanking is very little;
4, described hydraulic pump is the hydraulic pump of manual and electric one, still can pass through manual work under the non-transformer operating mode, has increased security reliability.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in the figure, a kind of gate safe locking device, comprise support arm 2, hydraulic cylinder 3 and hydraulic pump 4, support arm is fixed on the gate axle 5 by flange, hydraulic cylinder is installed on the support arm by flange, in the end of hydraulic cylinder push rod 1 is installed, be connected by hydraulic oil pipe between hydraulic cylinder and the hydraulic pump, fixing body of wall is provided with the some keyholes 6 that cooperate with hydraulic cylinder 3, described some keyholes 6 be with gate axle 5 serve as the axle be distributed on the body of wall, described keyhole 6 has insertion and extraction that certain taper makes things convenient for push rod 1 for having the conical blind hole of certain taper.Hydraulic pump is the hydraulic pump of manual and electric one, still can realize the locking and unlocking of gate safe locking device by stretching of hydraulic cylinder of manual manipulation hydraulic pump realization in device powers down.
