Abstract
The utility model discloses a headstock gear locking device and belongs to the technical field of headstock gears. The headstock gear locking device comprises a headstock gear and a gate swing arm which is connected with a gate shaft. A locking oil cylinder which is used by being matched with a preformed hole of a wall is arranged between the gate swing arm and the gate shaft. According to the headstock gear locking device, the locking oil cylinder which is used by being matched with the preformed hole of the wall is arranged so that basic headstock gear locking requirements can be met, safety performance under the state that a gate is closed can be increased, and meanwhile the device is reasonable and simple in structure, equipment investment cost is saved, the headstock gear locking device is suitable for being popularized and used in production operations, and great practicability is achieved.
Description
Technical field
The utility model belongs to the headstock gear technical field, is specifically related to a kind of headstock gear locking device.
Background technology
Hydraulic hoist extensively applies to all kinds of Hydraulic and Hydro-Power Engineerings, and the lifting of controlling all kinds of big-and-middle-sized cast irons and steel gate reaches the purpose of open and close.But because height of water is big before and after some gates, the pressure height that gate bears, when gate is in closed condition following time, hydraulic system stops, and the safety factor of gate is not high.
The utility model content
Goal of the invention: at deficiency of the prior art, the purpose of this utility model is to provide a kind of headstock gear locking device, can guarantee the security performance under gate in off position.
Technical scheme: a kind of headstock gear locking device, comprise interconnective headstock gear and gate swing arm, described gate swing arm links to each other with the gate door-hinge, is provided with the locked cylinder that the preformed hole with wall is used between described gate swing arm and the gate door-hinge.
Described headstock gear links to each other with hydraulic system.
Headstock gear locking device of the present utility model, by between gate swing arm and gate door-hinge locked cylinder being set, this locked cylinder is equivalent to the effect of a bearing pin, by preformed hole on body of wall, this locked cylinder stretches out and enters preformed hole, the locking when finishing closing gate; By the HYDRAULIC CONTROL SYSTEM headstock gear, simultaneously, this locked cylinder also is subjected to HYDRAULIC CONTROL SYSTEM, greatly reduces equipment investment cost, has saved the production site space.
Beneficial effect: compared with prior art, headstock gear locking device of the present utility model, by the locked cylinder that the preformed hole that arranges with body of wall is used, can finish basic headstock gear locking demand, can increase the security performance under the closing gate state again, simultaneously, this apparatus structure is reasonable, and is succinct, saved the equipment investment expense, suit in producing running, to apply, have good practicability.
Description of drawings
Fig. 1 is the structural representation of headstock gear locking device;
Fig. 2 is the working state schematic representation of headstock gear locking device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2, this headstock gear locking device comprises interconnective headstock gear 1 and gate swing arm 2, and gate swing arm 2 links to each other with gate door-hinge 3, is provided with the locked cylinder 4 that the preformed hole with wall 5 is used between gate swing arm 2 and the gate door-hinge 3; Wherein, headstock gear 1 links to each other with hydraulic system.
The course of work: during closed shutter, after hydraulic system started, headstock gear 1 stretched out and connects gate swing arm 2 rotations, drives closing gate, and when gate was closed fully, headstock gear 1 quit work, and locked cylinder 4 stretches out, and is connected system cut-off with the preformed hole of wall 5; During starting gate, hydraulic system starts, locked cylinder 4 withdrawals, and when the locked cylinder withdrawal put in place, when namely locked cylinder separated with body of wall fully, headstock gear 1 withdrawal drove gate opening.
This headstock gear locking device, the locked cylinder that is used by the preformed hole that arranges with body of wall, can finish basic headstock gear locking demand, can increase the security performance under the closing gate state again, simultaneously, this apparatus structure is reasonable, succinctly, save the equipment investment expense, suited in producing running, to apply, had good practicability.
