A hermetical preservative and compressive cover is installed on an upper end cover of the locking oil cylinder, and internally provided with a magnetostrictive displacement transducer of which a measuring rod is extended to a core hole of a hollow structure piston rod, and an induction ring is fixed on the ring. A locking plate is arranged on the underwater locking console, and an anti-shearing plate is arranged on one side of the locking console. The front end of the piston rod is connected with a locking shaft by an oil cylinder suspension head and a pin shaft, the pin shaft is provided with an induction measuring ring used for a limiting transducer, two limiting transducer seats are arranged on the gate web, and the locking shaft is connected with the underwater locking console in a locking way. The underwater hydraulic axis-penetrating locking device is characterized in that the locking shaft is arranged at the front end of the piston rod of the locking oil cylinder, and the penetration and escape of locking are performed by the forward and backward movement of the locking shaft, thereby realizing the locking function.
Description
Technical field
The present invention relates to gate locking device, especially relate to underwater hydraulic axis-penetrating locking device.
Background technology
Hydraulic lock assembly is to guarantee that can this gate satisfy the two-way supporting requirement in bottom, realizes the essential condition of gate two-way water blocking and locking.Be subjected to the restriction of gate arrangement form, the locking seat of gate can only be arranged on the gate embedded part, and long-term work under water.Adopt manual locking not possess operating condition, it is not high again that conventional formula automatically locks reliability, and when problem takes place under water, be difficult for solution.
Summary of the invention
The object of the present invention is to provide a kind of realization close the door locking, maintenance locking and safe and reliable underwater hydraulic axis-penetrating locking device.
For achieving the above object, the present invention can take following technical proposals:
Underwater hydraulic axis-penetrating locking device of the present invention comprises the locked cylinder that is arranged on gate girder lower end and is arranged on the platform of locking under water on the gate embedded part; Upper end cover at described locked cylinder is provided with sealing corrosion resistance to compression cover, is provided with magnetostrictive displacement sensor in it, and the measuring stick of described magnetostrictive displacement sensor extends in the core hole of hollow-core construction piston rod, and inductance loop is fixed on the described piston; The described platform that locks under water is provided with lockplate, is provided with shear resisting board in described lockplate one side; The piston rod front end hangs head by oil cylinder and bearing pin is connected with lock shaft, and described bearing pin is provided with the induction that is used for limit sensors and surveys ring, and the gate web is provided with two limit sensors seats; Described lock shaft is connected surely with the described stand lock that locks under water.
Described sealing corrosion resistance to compression cover links by flange and locked cylinder upper end cover.
Described lock shaft outer peripheral face is provided with self lubrication bearing.
The invention has the advantages that the piston rod front end at locked cylinder is provided with lock shaft, finish wearing off of locking, realize the function of locking by moving forward and backward of lock shaft; When gate was in the maintenance position, this device can make gate lock equally on inspection rack, made it possess the locking of closing the door, maintenance lock function.Hydraulic pressure locking device is under water worked for a long time under water, operating mode is abominable, so the upper end cover at locked cylinder is provided with sealing corrosion resistance to compression cover, be provided with magnetostrictive displacement sensor in it, anticorrosion resistance to compression case can long period of soaking under water, under 5m hydraulic pressure operate as normal, satisfy the instructions for use of equipment working condition, guarantee that sensor is reliable.The measuring stick of magnetostrictive displacement sensor extends in the core hole of hollow-core construction piston rod, inductance loop is fixed on the described piston, moving of the moving inductance loop of piston moving belt, carry out the stroke detection of locking device by measuring stick, good, stable to the compliance of integral body, signal to noise ratio is high and safe and reliable, the life-span is long.The piston rod front end hangs head by oil cylinder and bearing pin is connected with lock shaft, described bearing pin is provided with the induction that is used for limit sensors and surveys ring, two sensor holders are fixed to the place of two positions up and down of gate web respectively, and can adjust sensor holder flexibly and survey the distance of encircling with induction, seal with waterproof gasket cement afterwards, tighten the locking nut on the sensor holder at last, simple, the good operation performance of strong and field adjustable to the ambient conditions adaptive capacity.After piston rod was stretched, is reduced to the position, induction was surveyed ring and is sent signal, system-down with sensor sensing.Induction survey ring can overcome piston rod and radially rotate influence, realizes 360 degree inductions, makes it more accurate.
