Detailed Description
The invention is described in further detail below with reference to the figures and the detailed description.
Referring to the attached figures 1 to 4 of the specification, the blowout preventer overhauling platform is a mechanical device for installing and overhauling a blowout preventer, adopts full hydraulic control, can respectively overhaul the positions at two sides of the blowout preventer, and can be retracted during non-working period without influencing drilling construction.
The arm support 2 is hinged by a plurality of connecting rods to form a scissor connecting rod structure, the arm support 2 generates scissor lifting motion through a telescopic mechanism, one of the two groups of connecting rods at the upper end part of the arm support is hinged with the bottom of the working platform 1, the other group of connecting rods is matched with a sliding support at the bottom of the working platform 1, one of the two groups of connecting rods at the lower end part of the arm support is hinged with the upper surface of the lifting base 6, and the other group of connecting rods is matched with the sliding support at the upper surface of.
In the above embodiment, the telescopic mechanism is one of a hydraulic oil cylinder, a hydraulic air cylinder or a linear driving screw. A safety valve is arranged in a pipeline of the hydraulic oil cylinder or the hydraulic air cylinder. The safety valve comprises one or more of a one-way valve, a flow regulating valve, an electromagnetic valve and an overflow valve.
The blowout preventer overhauling platform consists of supporting legs 3, a retracting arm 4, a lifting base 6, an arm support 2 and a working platform 1. One end of the lifting base 6 is connected with the derrick base 5 through a hinge lug, the other end of the lifting base is provided with a supporting leg 3, the supporting leg 3 is hinged with the lifting base 6, and the supporting leg 3 can swing to two sides of the lifting base 6 during recovery; the retractable arm 4 consists of a hydraulic telescopic oil cylinder and a piston rod, two ends of the retractable arm 4 are respectively hinged with the derrick base 5 and the lifting base 6, when the retractable arm 4 is retracted, the lifting base 6 is erected on the derrick base 5, and the supporting legs 3 are retracted to two sides of the lifting base 6; when receiving and releasing arm 4 and stretching out, lifting pedestal 6 is the horizontality, and supporting leg 3 swung to lifting pedestal 6 distal end and dropped to ground this moment to support lifting pedestal 6.
The lifting base 6 is formed by welding steel plates with corresponding strength. The upper plane of the lifting base 6 is provided with a hinge lug and a pulley for mounting the arm support 2. The arm support 2 is in a scissor fork connecting rod structure formed by hinging a plurality of connecting rods, so that the arm support 2 generates scissor fork type lifting motion, and each connecting rod of the arm support 2 is made of a high-strength seamless rectangular pipe, so that the arm support is high in strength and attractive in appearance. The hydraulic cylinder pushes the tail end of the bottom connecting rod of the arm support 2 to slide in the sliding grooves of the upper plane of the lifting base 6 and the lower plane of the working platform, the arm support 2 extends or shortens in the vertical direction, and the working platform 1 is driven to move up and down.

The working principle is as follows: the hydraulic cylinder absorbs oil from the oil pump, pushes a piston in the hydraulic cylinder, and the jacking cross arm frame 2 vertically rises; when the pressure oil drops, the pressure oil flows back to the oil tank through the electromagnetic valve under the monitoring of the speed limiting valve and the flow regulating valve. When the hydraulic cylinder is overloaded, the pressure oil output by the oil pump directly flows back to the oil tank through an overflow valve (safety valve). In order to prevent the oil pipe from breaking and generating an uncontrolled descending accident, a one-way speed limiting valve is arranged on an oil inlet pipeline (also used as an oil return pipeline) of each hydraulic cylinder, and the oil pipe can be ensured to descend at a normal descending speed even under the condition that the oil pipe breaks.
