[0034] The application discloses a water supply pry for marine cementing operation, and relates to the field of marine cementing operation. The operation console support 4 is used for controlling the water pump 7 and the oil production machine 3. The movable vertical beam 1-3 moves along the opening direction of the opening horizontal beam 1-1. The movable support 6 moves along the opening direction of the movable vertical beam 1-3. The pry-mounted device can realize single or multiple water pumps 7 to provide clean water with different pressures and different flow rates for marine cementing operation by increasing or decreasing the movable vertical beam 1-3 and the movable support 6, so as to meet the requirements of different marine working conditions. The structure is compact, the occupied space is small, the lifting lug 1-2 is used for lifting and moving, the lifting and moving are convenient, the problem of narrow deck space of the marine drilling platform and limited lifting capacity of the platform crane is solved. The clasp spring II 6-4 has the same structure as the clasp spring I 1-3-2. The opening horizontal beam 1-1 is a single-side oval opening square steel pipe, the distance between the centers of the two adjacent ellipses is L1, the fixed vertical beam 1-5 is not opened, and the square steel pipe size of the opening horizontal beam 1-1 is the same as that of the fixed vertical beam 1-5. The opening square steel pipe 1-3-1 is a single-side oval opening square steel pipe, the opening is upward, and the distance between the centers of the two adjacent ellipses is L2. The size of the opening square steel pipe 1-3-1 is smaller than that of the opening horizontal beam 1-1. When the clasp spring I 1-3-2 at the lower movable vertical beam 1-3 is loosened, the movable vertical beam 1-3 can move along the opening direction of the opening horizontal beam 1-1. When the clasp spring I 1-3-2 at the movable vertical beam 1-3 is loosened, the movable vertical beam 1-3 is fixed and locked by means of the oval hole at the opening horizontal beam 1-1.

[0035] Pressing the spring 6-4, the movable support 6 moves along the opening direction of the moving vertical beam 1-3. Loosing the spring 6-4, the movable support 6 is fixed and locked by the oval hole of the moving vertical beam 1-3. Loading the top end of the wedge-shaped seat 6-5, the wedge-shaped seat 6-5 moves downward, the support pin 6-3 moves outward along the wedge-shaped part of the wedge-shaped seat 6-5, and the spring 6-2 at the end of the support pin 6-3 is in tension. If the applied load is large enough, the two support pins 6-3 continue to move outward until they fall into the clamping groove at the end of the sliding groove. When there is no equipment on the top, the pin shaft slides horizontally in the sliding groove. Under the heavy pressure of the equipment, the two pin shafts slide into the clamping groove, and the load on the top end of the wedge-shaped seat 6-5 is removed. The spring 6-2 at the end of the support pin 6-3 starts to contract from the tension state. During the contraction of the spring 6-2, the two support pins 6-3 are driven to move inward along the wedge-shaped part of the wedge-shaped seat 6-5. The height of the support pin 6-3 on either side of the movable support 6 can also be adjusted to achieve different angles of fixation. Manually adjusting the wedge-shaped seat 6-5 to rise, the spring 6-2 is in a natural state. The disc body 6-6-5 has a diameter of L3, L3>L1=L2. On the bearing base 1, L1 and L2 are adjusted per unit length, and L3 is adjusted by rotating the disc to make fine adjustments. By rotating the disc, the direction of the T-shaped groove is adjusted to achieve fine adjustment in the XY direction. When the spring 6-8 is in a compressed state, the horizontal pin shaft 6-6-2 and the horizontal pin shaft 6-6-4 on the disc body 6-6-5, and the vertical pin shaft 6-6-3 and the vertical pin shaft 6-6-6 are inserted into the pin hole at the top of the wedge-shaped seat 6-5. When the spring 6-8 is in a natural state, the rotating disc 6-6 rotates around the main pin shaft 6-6-1, the fixed bolt 6-7 moves along the "T" shaped groove, moves to the appropriate position, and tightens the fixed bolt 6-7. The diesel oil tank 2 is installed inside the bearing base 1. Moving the diesel oil tank 2 along the opening direction of the opening cross beam 1-1 can adjust the load distribution of the entire skid-mounted device. The horizontal projection of the rainwater collection container 12 can completely cover the horizontal projection of the entire skid-mounted device. The rainwater collection container 12 has small holes around the edge of the rain shield 12-3. The rainwater collected by the rain shield 12-3 flows into the rainwater collection container 12 through the small holes. The rainwater collected by the rainwater collection container 12 can be treated to provide cooling water for the diesel engine cooling. The rainwater collector 12 is movable, and can be removed when the skid-mounted device is working indoors. At the same time, the diesel engine or motor as the power component of the well cementing equipment, to avoid the erosion of rainwater and sea waves and the exposure to sunlight, the rainwater collector 12 provides protection for the power equipment working in the open air. The reliability of the diesel engine system operation is improved.

[0036] The application is a water supply pry for marine cementing operation. When a single diesel engine drives a single water pump, the installation position of the diesel engine driving the water pump is calculated first, and the hollow square structure composed of the opening cross beam 1-1 and the fixed vertical beam 1-5 is welded. Then, the movable vertical beam 1-3 and the movable support seat 6 are increased or decreased to meet the support required by the diesel engine 3, the console support 4, the shaft coupling guard 5, the water pump 7, the water inlet pipe support 8 and the water outlet pipe support 10. The load distribution of the whole device is estimated, and the position of the diesel engine oil tank 2 in the load-bearing base 1 is adjusted. The "Z" shaped groove of a certain depth of the support seat 6-1 is selected. The support pin 6-3 is placed and the spring I 6-2 is hung. The rotating disc 6-6 is placed on the wedge-shaped seat 6-5, and the whole is placed in the middle of the support pin 6-3. The diesel engine 3 to be fixed is lifted, the clamping spring I 1-3-2 on the movable vertical beam 1-3 and the clamping spring II 6-4 on the movable support seat 6 are pressed, the position of the movable vertical beam 1-3 and the movable support seat 6 is adjusted, and then the clamping spring I 1-3-2 and the clamping spring II 6-4 are loosened to fix the position of the diesel engine 3 base on one side. Then, the rotating disc 6-6 of the movable support seat 6 is rotated, so that the "T" shaped groove hole at the upper part of the rotating disc 6-6 is horizontal or vertical, the position of the fixed bolt 6-7 in the "T" shaped groove hole of the rotating disc 6-6 is adjusted, and the other side position of the diesel engine 3 is tightened. Similarly, the positions of the console support 4, the shaft coupling guard 5 and the water inlet pipe support 8 and other equipment are fixed.

[0037] After the water supply equipment on the load-bearing base 1 is fixed, the load-bearing base 1 and the frame body 11 are hinged through the connecting lug seat 9. The frame body 11 can provide support for the accessories required for the operation of the diesel engine 3. The legs 12-1 of the rainwater collector 12 are fixed to the frame body 11 by bolts. The rainwater collected in the rainwater collection container 12 can be treated to provide cooling water for the cooling of the diesel engine.

[0038] When the water pump 7 is driven by an electric motor, the water supply equipment on the load-bearing base 1 is fixed with the diesel engine 3. Whether the frame body 11 and the rainwater collector 12 are installed can be determined according to the on-site operation environment.

[0039] The water supply pry for marine cementing operation can increase or decrease the number of movable vertical beams 1-3 and movable support seats 6, so as to realize the supply of water with different pressures and different flow rates by a single or multiple water pumps 7 for marine cementing operation site.

[0040] The water supply pry for marine cementing operation not only applies to diesel engine 3 or electric motor driven water pump 7 to realize water supply, but also meets the installation requirements of other modules such as ash supply device and high-pressure piston pump required for marine cementing. When the diesel engine 3 drives the water pump 7, the problem of insufficient power supply interface or limited platform capacity on the marine cementing operation site is solved. The oil tank 2 used by the diesel engine is placed in the load-bearing base 1, which is beneficial to oil suction and oil return of the diesel engine. At the same time, the oil tank 2 can move along the load-bearing base 1 to adjust the load distribution of the whole device, and the oil tank 2 has good heat dissipation.

[0041] The water supply pry for marine cementing operation solves the problem that the existing cementing pry cannot meet the platform field operation condition due to the narrow deck space of the marine drilling platform and the limited helicopter transportation capacity. The water supply pry for marine cementing operation as the modular equipment of the marine cementing pry has the advantages of compact structure, small floor area and light equipment weight, and solves the problems of the lifting capacity of the platform crane and the narrow deck space. The water supply pry can adapt to single or multiple water pumps, can provide clean water with different flow rates and different pressures for marine cementing operation, and can meet the cementing operation requirements of different marine working conditions. The water supply pry can not only realize diesel engine or motor driven water pump to realize water supply, but also can meet the installation requirements of the ash supply device, high-pressure piston pump and other modules required by marine cementing.
