[0002] Unlike asphalt tankers, chemical tankers are equipped with a total of 12 cargo pumps, 2 SLOP pumps, 2 ballast pumps and 1 residual liquid pump. Since the cargo pumps can be up to 17.91m in length, according to the manufacturer's requirements, the above pumps need to be equipped with several intermediate supports and fixed on the corrugated bulkhead or transverse bulkhead. According to the equipment manufacturer's recommendation, one end of the intermediate support is connected to the flange on the cargo pump shaft, and the other end is fixed to the transverse bulkhead. The transverse bulkhead end needs to be welded with a fixing bracket or eye plate.

[0003] However, when the above-mentioned chemical tanker liquid cargo pump is installed at a designated position through a flange, after the liquid cargo pump pipe is connected to the flange, a gap will be generated at the connection due to the environment or internal liquid characteristics when the pump pipe is used in connection with the flange, resulting in a high damage rate between the pump pipe and the flange after the pump pipe is rigidly connected. Utility Model Content

[0029] The crossbar 1 is used to hoist the flange seat 3 through the suspenders 2 on both sides. One end of the suspender 2 is fixedly connected to the crossbar 1 by a fixing bolt 21, and a reinforcement block 22 is formed between the other end of the suspender 2 and the two sides of the flange seat 3 by welding. This allows the flange seat 3 and the two sets of suspenders 2 to be disassembled from the crossbar 1. The pump pipe 4 is movable through the flange seat 3, so that the liquid cargo pump pipe 4 of the chemical tanker can be hoisted on the hull through multiple sets of horizontally evenly spaced crossbars 1;

[0030] By rotating the worm 91, the worm 91 drives the worm wheel ring 82 outside the rotating ring 8, so that the synchronous gear ring 81 outside the rotating ring 8 drives multiple sets of synchronous gears 72, so that the second bevel gear 71 that makes the synchronous gear 72 rotate synchronously drives multiple sets of corresponding first bevel gears 61, so that the multiple sets of screws 52 on the inner diameter of the flange seat 3 rotate synchronously, so that the positioning sleeve 5 drives the wedge block 51 below to press against the outside of the pump pipe 4 in the flange seat 3, and the rubber sleeve outside the wedge block 51 can play an elastic connection role between the inner wall of the flange seat 3 and the pump pipe 4. In this way, when the liquid in the pump pipe 4 expands and contracts due to heat and contracts, the connection between the flange seat 3 and the pump pipe 4 can still be ensured to be tight;

[0031] The wedge block 51 at the bottom end of the positioning sleeve 5 can slide in the annular groove 42, and can enable the guide block 512 at the bottom of the positioning sleeve 5 to slide on the guide groove 511. The wedge block 51 can slide along the annular groove 42 to fine-tune its position. In this way, after the connection between the pump pipe 4 and the flange seat 3 is deformed, the connection between the pump pipe 4 and the flange seat 3 can still be tightened by sliding adjustment of the wedge block 51.

[0032] Among them, the flange seat 3 is symmetrically provided with hangers 2 on both sides, and the connection between the hangers 2 and the cross bar 1 is fixedly installed with fixing bolts 21. The connection between the hangers 2 and the flange seat 3 is integrally formed with a reinforcement block 22. The cross bar 1 hangs the flange seat 3 through the hangers 2 on both sides. One end of the hanger 2 is fixedly connected to the cross bar 1 through the fixing bolts 21, and the other end of the hanger 2 is integrally formed with the two sides of the flange seat 3 by welding.

The wedge block 51 at the bottom end of the positioning sleeve 5 can slide in the annular groove 42 and can enable the guide block 512 at the bottom of the positioning sleeve 5 to slide on the guide groove 511. The wedge block 51 can slide along the annular groove 42 to fine-tune the position. In this way, after the connection between the pump pipe 4 and the flange seat 3 is deformed, the connection between the pump pipe 4 and the flange seat 3 can still be tightened by sliding adjustment of the wedge block 51.

[0034] Among them, the mounting block 6 corresponds to the slot 41 one by one, the outer edge of the first bevel gear 61 is meshed with the outer edge of the corresponding second bevel gear 71, the top of the screw 52 is rotatably mounted on the top of the corresponding mounting block 6, and the outer edges of multiple sets of synchronous gears 72 are respectively meshed with the outer edges of the synchronous ring gear 81.

In this way, when the liquid in the pump pipe 4 expands and contracts due to heat and cold, the connection between the flange seat 3 and the pump pipe 4 can still be ensured to be tight.

[0036] Working principle: When in use, first, the crossbar 1 is hoisted to the flange seat 3 through the suspenders 2 on both sides. One end of the suspender 2 is fixedly connected to the crossbar 1 by a fixing bolt 21, and a reinforcement block 22 is integrally formed between the other end of the suspender 2 and the two sides of the flange seat 3 by welding. The pump pipe 4 is movable through the flange seat 3, so that the liquid cargo pump pipe 4 of the chemical tanker can be hoisted on the hull through multiple groups of horizontally evenly spaced crossbars 1;

[0037] Then, by rotating the worm 91, the worm 91 drives the worm wheel ring 82 outside the rotating ring 8, so that the synchronous gear ring 81 outside the rotating ring 8 drives multiple sets of synchronous gears 72, so that the second bevel gear 71 that makes the synchronous gear 72 rotate synchronously drives multiple sets of corresponding first bevel gears 61, so that the multiple sets of screws 52 on the inner diameter of the flange seat 3 rotate synchronously, so that the positioning sleeve 5 drives the wedge block 51 below to press against the outside of the pump pipe 4 in the flange seat 3, and the rubber sleeve outside the wedge block 51 can play an elastic connection role between the inner wall of the flange seat 3 and the pump pipe 4, so that when the liquid in the pump pipe 4 expands and contracts due to heat, the connection between the flange seat 3 and the pump pipe 4 can still be ensured to be tight;

[0038] Finally, when inspecting and adjusting the pump pipe 4 and the flange seat 3, the wedge block 51 at the bottom end of the positioning sleeve 5 can slide in the annular groove 42, and the guide block 512 at the bottom of the positioning sleeve 5 can slide on the guide groove 511. The wedge block 51 can slide along the annular groove 42 to fine-tune the position. In this way, after the connection between the pump pipe 4 and the flange seat 3 is deformed, the connection between the pump pipe 4 and the flange seat 3 can still be tightened by sliding adjustment of the wedge block 51.
