Description
Technical field
What the utility model patent related to is a kind of energy-saving safeguard device that is used for lifting platform, belongs to mechanical field.
Background technology
Along with the exploitation of ocean, increasing ocean platform and other marine structures have obtained building and using.Wherein lift platform is few because of steel using amount, cost is low and the efficient advantages of higher has obtained extensive use, and it almost can continue lifting under the various sea situations of design, but considers from energy-conservation and safety work aspect, also has two subject matters.When first platform descends, need configuration resistor box power consumption device, a large amount of decline potential energy could be consumed,, the hydraulic oil heating is lost in vain perhaps by the hydraulic throttle form; It two is that brake easily takes place in the platform decline process is out of control, causes broken teeth, and platform structure is impaired, jeopardizes platform safety, for example, two platforms just took place in zone, the Bohai Sea in recent years glide the serious safety problem out of control of braking suddenly.A kind of energy-saving safeguard device that is used for lifting platform has been proposed for this reason.
The utility model patent is just for realizing what above-mentioned requirements designed, purpose is to make full use of the potential energy in the platform decline, the heating loss of minimizing system, it is out of control and the risk that occurs reaches the purpose that the potential energy that effectively platform descended transforms storage to reduce brake in the platform decline process.
The utility model patent content
The technical problem that the utility model patent will solve provides a kind of energy-saving safeguard device that is used for lifting platform, this device can transform the potential energy in the platform decline process storage effectively and avoid because of the brake risk that occurs out of control in the platform decline process, and the purpose of the utility model patent is to provide a kind of energy-saving safeguard device for lifting platform.
For addressing the above problem, the utility model patent is achieved in that the utility model patent mainly comprises lifting pole, tooth bar, pinion, gearbox, shaft coupling, hydraulic pump, oil-absorbing pipeline, pressure pipeline, fuel tank, unidirectional proportional throttle valve, pressure-regulating valve, holds fluid cylinder, gas compressed package, pressure sensor, monitoring unit; One of its feature is lifting pole, tooth bar, pinion, axle, gearbox, shaft coupling, hydraulic pump, unidirectional proportional throttle valve, hold fluid cylinder and gas compressed package is connected before and after successively.Two of its feature is to be evenly equipped with tooth bar along lifting pole.Three of its feature is that hydraulic pump links to each other with fuel tank by oil-absorbing pipeline, is connected with pressure-regulating valve with unidirectional proportional throttle valve by pressure pipeline.Four of its feature is that monitoring unit is connected with pressure sensor with unidirectional proportional throttle valve.In platform decline process, by platform weight-driven pinion rotation, drive hydraulic pump by the gearbox speedup, to holding fluid cylinder pumping pressure oil, implementation platform decline potential energy converting and energy is the oil liquid pressure energy, simultaneously, when platform decline generation brake is out of control,, realize the oil pressure adjustment automatically by pressure-regulating valve, unidirectional ratio adjusting valve and monitoring unit, increase the pinion rotation resistance, reach the purpose of safe auxiliary brake.When platform rises, hold fluid cylinder release pressure oil, drive the hydraulic pump rotation, the speed increaser reverse operation plays the effect of deceleration, improves output drive strength thereby reduce rotating speed, makes pinion drive platform and rises, reduce the configuration of lift platform power demand, reach purpose of energy saving.
The utility model patent can make the effect of holding liquid in the platform decline process and playing safe auxiliary brake, can significantly reduce the heating loss of system in the platform decline process, eliminates brake hidden danger out of control in the platform decline process.Device has simple and reliable for structure, advantage convenient to operation.The hydraulic pressure of the utility model patent holds hydraulic control system technology can carry out the energy storage effectively, has very high energy-saving application and is worth.
