Problems solved by technology

One is that when the platform descends, it is necessary to configure a resistance cabinet energy consumption device to consume a large amount of descending potential energy, or through hydraulic throttling to make the hydraulic oil heat and lose; Cause broken teeth, damage the platform structure, and endanger the safety of the platform
When the platform rises, the pressure energy in the accumulator is converted into potential energy, the pressure in the early stage is high, the pressure in the later stage is insufficient, and the front and rear speeds are uneven

Embodiment Construction

[0010] The technical solutions claimed in the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 As shown, the energy-saving safety device in this embodiment includes a lifting pile 1, a rack 2, a speed-increasing box 3, a hydraulic pump 4, two pressure energy storage devices 5, a monitoring unit 6, a pressure regulating valve 7, and a fuel tank 8. Wherein the rack 2 is connected with the lifting pile 1, and the lifting pile 1 is connected by the rack 2. The input shaft of speed-up box 3 is provided with transmission gear, and transmission gear meshes with rack 2 to make rack 2 move and drive input shaft to rotate, and input shaft can also drive rack 2 to move in turn when rotating. When the output shaft of the gearbox 3 is connected with the hydraulic pump 4 through a coupling so that the output shaft rotates, the hydraulic pump 4 can be started to extract hydraulic oil. When...

Abstract

The invention discloses an energy saving safety device for lifting an ocean platform and a working method thereof. The device comprises a lifting column, a rack, a gearbox, a hydraulic pump, at least pressure energy storage device, a monitoring unit, a pressure adjusting valve and an oil tank. The hydraulic pump is sequentially connected with the pressure energy storage devices, the monitoring unit, the pressure adjusting valve and the oil tank in a circulation mode, wherein the pressure energy storage device is connected on an oil delivery pipeline between the hydraulic pump and the pressure adjusting valve. Each pressure energy storage device comprises a proportional throttling valve, a liquid storage cylinder, a gas compression bag, a pressure sensor and an electromagnetic valve, wherein the proportional throttling valve is connected with the electromagnetic valve in parallel, two ends of the proportional throttling valve and the electromagnetic valve are connected with the liquid storage cylinder and the oil delivery pipeline, and the liquid storage cylinder is connected with the gas compression bag and the pressure sensor.

Description

technical field [0001] The invention relates to the technical field of offshore platform equipment, in particular to a working method of an energy-saving safety device for lifting and lowering an offshore platform. Background technique [0002] With the development of the ocean, more and more ocean platforms and other ocean structures have been constructed and applied. However, there are two main problems in terms of energy saving and safe operation. One is that when the platform descends, it is necessary to configure a resistance cabinet energy consumption device to consume a large amount of descending potential energy, or through hydraulic throttling to make the hydraulic oil heat and lose; Cause broken teeth, damage the platform structure, and endanger the safety of the platform. When the platform rises, the pressure energy in the accumulator is converted into potential energy, the pressure in the early stage is high, the pressure in the later stage is insufficient, and...
