DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Reference Figure 1-Figure 5 As shown, a high-pressure resistant combined fracturing manifold comprises a main pipe 1, a plurality of branch pipes 2 are arranged on the surface of the main pipe 1, and mounting rings 3 are fixedly installed at both ends of the main pipe 1, a plurality of trapezoidal plug rods 4 are fixedly installed on the surface of one mounting ring 3 in a circular shape, and a plurality of sockets 5 for inserting the plurality of plug rods 4 are opened in a circular shape on the surface of the other mounting ring 3, and sealing rings 18 are bonded to the sides of the two mounting rings 3 away from each other, and the sealing rings 18 are made of rubber, and the sealing rings 18 made of rubber can improve the sealing performance; a rectangular groove is vertically opened on the wall of the socket 5 6. The outer ring wall of the mounting ring 3 having multiple sockets 5 is provided with multiple through holes respectively connected with the multiple rectangular grooves 6. A slide rod 7 is slidably inserted in the through hole. A triangular locking block 8 is fixedly installed at one end of the slide rod 7 located in the socket 5. The slide rod 7 is connected to the mounting ring 3 through a telescopic component. The telescopic component includes a telescopic spring 10 sleeved on the slide rod 7. A mounting plate is fixedly installed at one end of the slide rod 7 located outside. Both ends of the telescopic spring 10 are fixedly connected to the mounting plate and the mounting ring 3 respectively. A locking port 9 for the locking block 8 to enter is provided on the surface of the insertion rod 4.

[0020] When it is necessary to splice two main pipes 1, first align the multiple insertion rods 4 at the end of one of the main pipes 1 with the multiple sockets 5 at the end of the other main pipe 1 and insert them. When the multiple insertion rods 4 enter the multiple sockets 5, the inclined surface of the insertion rod 4 will slide in contact with the inclined surface of the locking block 8, the locking block 8 will move, and the telescopic spring 10 will stretch until the ends of the two main pipes 1 are butted against each other. At this time, the locking block 8 will correspond to the position of the locking port 9, and the pressing force of the insertion rod 4 on the locking block 8 disappears. The locking block 8 will quickly move and reset under the elastic potential energy of the telescopic spring 10, and be inserted into the locking port 9, thereby completing the splicing of the two main pipes 1. When disassembly is required, it is only necessary to control the movement of the multiple sliding rods 7 so that the multiple locking blocks 8 are respectively moved out of the multiple locking ports 9 to release the installation of the two main pipes 1, which is convenient and quick.

[0021] A pressing assembly is provided on the surface of the mounting ring 3 with multiple sockets 5, and the pressing assembly is used to control the multiple sliding rods 7 to move together. The pressing assembly includes a slip ring 11 slidably sleeved on the main pipe 1, a plurality of trapezoidal pressing plates 12 fixedly mounted on the surface of the slip ring 11 in a circular shape, and a plurality of inclined plates 13 respectively fixedly mounted on the surfaces of the plurality of mounting plates. A plurality of first spring rods 14 are fixedly mounted on the surface of the slip ring 11, and one end of the plurality of first spring rods 14 are fixedly connected to the surface of the mounting ring 3, and the inclined surfaces of the plurality of pressing plates 12 are respectively arranged face to face with the inclined surfaces of the plurality of inclined plates 13.

[0022] When the two main pipes 1 need to be disassembled, the movement of the control slip ring 11 can be used to make the inclined surfaces of the multiple pressure plates 12 slide and contact with the inclined surfaces of the multiple inclined plates 13 respectively. Under the action of the inclined surface pressure, the multiple slide bars 7 will move together and respectively move out of the multiple locking blocks 8 from the multiple locking ports 9, thereby releasing the installation between the two main pipes 1. The movement of multiple slide bars 7 can be controlled simultaneously without having to be controlled one by one.

[0023] A plurality of second spring rods 15 are fixedly mounted on the surface of the mounting ring 3 on which a plurality of insertion rods 4 are fixedly mounted, a U-shaped connecting rod 16 is fixedly mounted on one end of the second spring rod 15, and a limiting ring 17 is fixedly mounted on the ends of the two connecting rods 16. The limiting ring 17 is slidably sleeved on the main pipe 1 and corresponds to the positions of the plurality of locking ports 9.

[0024] When the two main pipes 1 are spliced, the limiting ring 17 will correspond to the position of the multiple slide rods 7. At this time, the multiple slide rods 7 are blocked by the limiting ring 17 and cannot move out of the locking port 9 with the locking block 8, thereby improving the stability of the splicing of the multiple main pipes 1. When the splicing needs to be released, it is necessary to first control the second spring rod 15 to stretch so that the limiting ring 17 moves until the limiting ring 17 moves to no longer correspond to the position of the multiple slide rods 7. At this time, the multiple slide rods 7 can be controlled to move, thereby releasing the splicing between the multiple main pipes 1.

[0025] When the plurality of plug rods 4 are inserted into the plurality of sockets 5 at the end of one of the plurality of pipes 1, the inclined surfaces of the plug rods 4 will slide in contact with the inclined surfaces of the locking blocks 8, the locking blocks 8 will move, and the telescopic component will stretch until the ends of the two pipes 1 abut against each other, at which time the locking blocks 8 will correspond to the positions of the locking ports 9, and the pressing force exerted by the plug rods 4 on the locking blocks 8 will disappear. The locking blocks 8 will quickly move and reset under the elastic potential energy of the telescopic component and be inserted into the locking ports 9, thereby completing the splicing of the two pipes 1. When disassembly is required, it is only necessary to control the movement of the plurality of sliding rods 7 so that the plurality of locking blocks 8 are respectively moved out of the plurality of locking ports 9 to release the installation of the two pipes 1. It is convenient and quick, and can replace the screw and nut fixings to quickly complete the splicing of the plurality of pipes 1, avoid the cumbersome steps of using the screw and nut fixings, and improve the work efficiency of disassembling and assembling the plurality of pipes 1.
