Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, be access lock locking device provided by the invention, this device is arranged on access lock door-plate, locks access lock door-plate, thus ensures sealing and the safety of access lock.
Locking plug 1 is Y-shaped structure, and it comprises two branches 9, and the medial surface of each branch 9 is provided with locking door bolt 6, and the lateral surface of each branch 9 is connected with access lock door-plate, and locking plug 1 can move with door-plate together with the locking door bolt on it.Locking briquetting 7 is provided with between two locking door bolts 6, this locking briquetting 7 is connected with the power transmission shaft 8 of access lock transmission system, can 90 degree of rotations under the drive of power transmission shaft 8, when locking briquetting 7 and rotating to upright position by horizontal level, locking briquetting 7 compresses locking door bolt 6.The thrust of locking door bolt 6 in the future self-locking briquetting 7 passes to locking plug 1, and the thrust of locking plug 1 door bolt of self-locking in the future 6 again passes to gate door-plate, thus is locked by gate door-plate.
It should be noted that, the locking plug 1 of above-mentioned Y-shaped structure, is not limited to this shape, if the locking plug of other shapes can realize this function, all within protection scope of the present invention.
Wherein, lock door bolt 6 to be arranged on the medial surface of branch by the connecting axle 4 be applied on branch 9.Connecting axle 4 is supported by upper and lower two two sliding bearings 5, can assurance device rigidity, and locking can be made again to fasten 6 flexible rotatings with a bolt or latch.The tail end of connecting axle 4 is provided with retaining ring 3, and the top of retaining ring 3 is provided with end cap 2, and end cap 2 is bolted on the lateral surface of branch 9, in order to protect retaining ring 3 and internal construction.
Locking door bolt 6, in cylindric, can rotate freely under the drive of connecting axle 4, and reduction carrys out self-locking briquetting 7 and rotates the frictional force brought.
The seal face of locking briquetting 7 is set to arcwall face, rotates with locking briquetting 7, gives the locking coupling mechanism force that plug 1 increases gradually.
In addition, the branch 9 of locking plug 1 is set to resistance to designing cylindrical with the junction of door-plate, it can rotate after coordinating with door-plate within the specific limits, the unbalanced force produced when locking that locking briquetting 7 compresses both sides fastens 6 with a bolt or latch can be eliminated to a certain extent, guarantee unnecessary moment of torsion not to be passed to door-plate.
The course of work of the present invention is:
After access lock door-plate closes to design attitude, power transmission shaft 8 drives locking briquetting 7 to rotate, locking briquetting 7 seal face is designed to special arcwall face, along with the increase of the anglec of rotation, the thrust that locking briquetting 7 gives to lock door bolt 6 also increases thereupon, locking door bolt 6 rotates under frictional force effect, thrust is passed to door-plate by locking plug 1 simultaneously.
In sum, locking device of the present invention, structure is simple, transmission is convenient, locking tolerance is large, coupling mechanism force large, and during execution locking operation, locking torque change is steadily; Air lock can be widely used in particularly on nuclear power plant's access lock.
It should be noted that; above-mentioned specific embodiment is only exemplary; under above-mentioned instruction of the present invention, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion all drops in protection scope of the present invention.It will be understood by those skilled in the art that specific descriptions are above to explain object of the present invention, not for limiting the present invention.Protection scope of the present invention is by claim and equivalents thereof.
