Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, and in particular to a large-diameter socket-and-spigot grooved pipe connector and an installation method thereof. Background Art

[0002] As an advanced pipe connection component, the socket-type grooved pipe connector combines the advantages of socket-type and groove-type connections. It is mainly composed of key components such as socket, spigot, groove, sealing rubber ring and clamp. Its core function is to achieve a stable connection between two pipes and ensure that the liquid or gas in the pipeline system can be transmitted smoothly and efficiently. At the same time, its exquisite design ensures that the connection part has excellent sealing and stability.

[0003] However, in actual pipeline installation operations, due to the large mass of large-diameter pipelines, operators need to overcome the obstacle of gravity when inserting the spigot into the socket. This is not only difficult to operate and it is difficult to accurately control the insertion of the spigot into the socket, which affects the efficiency of pipeline installation, but also very easy to cause accidents such as pipeline slippage and collision due to careless operation. In addition, large-diameter clamps that are compatible with large-diameter pipelines also have the problem of large dead weight, which makes it inconvenient for operators to carry and install the clamps during installation, further aggravating the operational difficulty and potential risks of the entire installation process.

[0004] Therefore, it is necessary to provide a large-diameter socket-type grooved pipe connector and an installation method to solve the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a large-diameter socket-type grooved pipe connector and an installation method, which can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A large-caliber socket-type grooved pipe connector, installed between two pipes, comprises a connector housing, a socket assembly and a docking assembly are arranged inside the connector housing, the socket assembly comprises a socket pipe and a socket seat, a sealing ring is symmetrically fixedly connected to the outer side of the socket seat, a sealing sleeve is symmetrically fixedly connected to the outer side of the socket pipe, and the docking assembly comprises a docking structure and a driving structure; The docking structure includes a movable seat symmetrically arranged in the connecting head shell, the interior of the movable seat is symmetrically slidably connected with the docking seat, a spring is symmetrically fixedly connected between the two docking seats, a retaining ring is fixedly connected inside the docking seat, a bidirectional screw rod is symmetrically arranged inside the connecting head shell, and the interior of the movable seat is symmetrically slidably connected with movable blocks, and the movable blocks form a spiral pair transmission with the bidirectional screw rod.

[0008] As a further improvement of the above scheme, the outer side of the receiving tube is symmetrically fixedly connected with a connecting ring, the connecting ring is fixedly connected to the inside of the shell one, the movable seats are rotatably connected to the inside of the shell one, and the two bidirectional screw rods are symmetrically rotatably connected between the two support sleeves.

[0009] As a further improvement of the above scheme, the driving structure includes a driving shaft rotatably connected to the bottom of the shell one, a worm is fixedly connected to the outer side of the driving shaft, a ring gear is rotatably connected between the shell one and the shell two, the worm and the ring gear are meshed with each other, and a gear is fixedly connected to the outer side of the bidirectional screw, and the gear and the ring gear are meshed with each other.

[0010] As a further improvement of the above solution, a push block is symmetrically fixedly connected to one side of the movable block close to the movable seat, and a mounting groove is formed at one end of the docking seat close to the movable block, and a guide block is fixedly connected to the inner wall of the mounting groove.

[0011] As a further improvement of the above solution, square grooves are provided on the inner walls of the shell 1 and the shell 2, and the movable blocks are slidably connected in the square grooves.

[0013] The installation method of a large-diameter socket-type grooved pipe connector comprises the following steps: Step 1: After docking the housing 1 and the housing 2, install them on the outside of the two pipes in turn and adjust their positions; Step 2: Rotate the drive shaft so that the drive shaft drives the gear to rotate through the meshing connection between the worm and the gear ring and the meshing connection between the gear ring and the gear, and the gear drives the internal bidirectional lead screw to rotate; Step 3: The bidirectional screw drives the movable block to lock the position of the docking seat through the push block and the guide block to ensure that the pipe is stably clamped in the movable seat; Step 4: The moving block continues to move to push the moving seat to drive the pipeline to move into the receiving assembly; Step 5: Move the two pipes into the receiving pipe to squeeze the sealing rings at both ends of the receiving seat, so that the sealing rings are deformed to ensure the sealing of the two pipes.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 9 As shown, the present invention provides an embodiment: A large-caliber socket-type grooved pipe connector is installed between two pipes 2, including a connector housing 1, a receiving assembly 4 and a docking assembly 5 are arranged inside the connector housing 1, the receiving assembly 4 includes a receiving pipe 41 and a receiving seat 42, a sealing ring 43 is symmetrically fixedly connected to the outer side of the receiving seat 42, a sealing sleeve 44 is symmetrically fixedly connected to the outer side of the receiving pipe 41, and the docking assembly 5 includes a docking structure 51 and a driving structure 52; The docking structure 51 includes a movable seat 511 symmetrically arranged in the connector housing 1, the movable seat 511 is symmetrically slidably connected to the docking seat 512 inside, a spring 514 is symmetrically fixedly connected between the two docking seats 512, a retaining ring 513 is fixedly connected inside the docking seat 512, a bidirectional screw rod 516 is symmetrically arranged inside the connector housing 1, and a movable block 515 is symmetrically slidably connected to the inside of the movable seat 511, and the movable block 515 forms a spiral pair transmission with the bidirectional screw rod 516.

[0020] In practical application, the embodiment of the present invention is as follows: Figures 1 to 4 As shown, when installing a large-diameter socket-type grooved pipe connector, firstly, the connector housing 1 is placed on the outside of one of the pipes 2, then the two pipes 2 to be connected are moved to the predetermined connection position, and the connector housing 1 is adjusted to be placed on the butt joint of the two pipes 2, and the sealing sleeve 44 located on the outside of the socket pipe 41 realizes the preliminary sealing of the pipe 2; Then Figure 4 , Figure 5 , Figure 6 and Figure 7 , start the driving structure 52 in the docking assembly 5, drive the bidirectional screw 516 to rotate, because the movable block 515 and the bidirectional screw 516 form a spiral pair transmission, the rotation of the bidirectional screw 516 causes the movable block 515 to slide toward each other in the movable seat 511, and the movement of the movable block 515 pushes the docking seat 512 connected thereto to approach the outer wall of the pipe 2, and the clamping ring 513 fixed inside the docking seat 512 gradually clamps on the outer side of the pipe 2 to achieve preliminary positioning; In this process, Figures 4 to 7As shown, the spring 514 symmetrically fixed between the two docking seats 512 plays a role of buffering and adaptive adjustment, ensuring that the clamping ring 513 is always tightly and stably clamped on the outside of the pipe 2. After clamping, the movable block 515 continues to move, and drives the pipe 2 to complete the docking in the receiving component 4 through the movable seat 511, and cooperates with the sealing component of the receiving component 4 to finally achieve a stable connection between the two large-diameter pipes 2, while ensuring the sealing of the connection part and improving the safety of the docking of the large-diameter pipes 2.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the connector housing 1 includes a housing 11 and a housing 12, a bolt 13 is symmetrically slidably installed between the housing 11 and the housing 12, a nut 14 is threadedly connected to the bottom of the bolt 13, and a support sleeve 3 is symmetrically fixedly connected between the housing 11 and the housing 12.

[0022] When the embodiment of the present invention is actually used, before the pipeline 2 is docked, the shell 11 and the shell 2 12 are first docked, and the bolts 13 and the nuts 14 are used to ensure the firmness of the docking between the shell 11 and the shell 2 12, so as to form a connector shell 1 as a whole for docking between the two pipelines 2.

[0023] like Figure 3 and Figure 5 As shown, the outer side of the receiving tube 41 is symmetrically fixedly connected with a connecting ring 45, the connecting ring 45 is fixedly connected to the inside of the outer shell 11, the movable seat 511 is rotatably connected to the inside of the outer shell 11, and the two bidirectional screw rods 516 are symmetrically rotatably connected between the two support sleeves 3.

[0024] When the embodiment of the present invention is actually used, the receiving tube 41 is fixedly installed on the housing 11 through the connecting ring 45, so that the receiving component 4 is installed as a whole in the connector housing 1, ensuring that during the docking process of the pipe 2, the receiving tube 41 supports the pipe 2, and the docking part is squeezed and sealed by the receiving seat 42 and the sealing ring 43, thereby ensuring the sealing of the docking end of the pipe 2.

[0025] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the driving structure 52 includes a driving shaft 521 rotatably connected to the bottom of the housing 11, a worm 524 is fixedly connected to the outer side of the driving shaft 521, a ring gear 522 is rotatably connected between the housing 11 and the housing 2 12, the worm 524 and the ring gear 522 are meshed with each other, and a gear 523 is fixedly connected to the outer side of the bidirectional lead screw 516, and the gear 523 and the ring gear 522 are meshed with each other.

[0026] When the embodiment of the present invention is actually used, the operator rotates the drive shaft 521 rotatably connected to the bottom of the housing 11 through a tool, and the drive shaft 521 then drives the worm 524 rigidly fixed on its outside to rotate synchronously around the axis. Since the worm 524 is in a meshing state with the ring gear 522 rotatably connected between the housing 11 and the housing 2 12, the rotational motion of the worm 524 is transmitted, and the ring gear 522 is driven to rotate accordingly within a limited rotation plane. At the same time, the gear 523 fixedly connected to the outside of the two-way screw rod 516 is also meshed with the ring gear 522. The rotation of the ring gear 522 prompts the gear 523 to drive the two-way screw rod 516 integrated therewith to rotate synchronously around its own axis.

[0027] like Figures 5 to 7 As shown, a push block 517 is symmetrically fixedly connected to one side of the movable block 515 close to the movable seat 511 , and a mounting groove 518 is formed at one end of the docking seat 512 close to the movable block 515 , and a guide block 519 is fixedly connected to the inner wall of the mounting groove 518 .

[0028] When the embodiment of the present invention is actually used, the movable block 515 pushes the guide block 519 in the installation groove 518 through the push block 517 during the movement, so that the docking seat 512 drives the clamping ring 513 to clamp the outside of the pipe 2 to avoid looseness, ensuring that the movement of the movable seat 511 can drive the pipe 2 to move synchronously to achieve precise docking.

[0029] like Figure 4 and Figure 5 As shown, square grooves are provided on the inner walls of the first housing 11 and the second housing 12, and the movable blocks 515 are slidably connected in the square grooves.

[0030] When the embodiment of the present invention is actually used, the sliding of the movable block 515 in the square groove can ensure the stability of the sliding of the movable block 515 and ensure that the sliding of the movable block 515 driven by the bidirectional screw rod 516 will not cause position deviation.

[0031] like Figure 4 , Figure 5 and Figure 8 As shown, an annular groove is provided on the inner wall of the housing 1 11 and the housing 2 12, and the gear ring 522 is rotatably connected in the annular groove.

[0032] In actual application of the embodiment of the present invention, the ring gear 522 is rotatably installed in the annular grooves on the housing 1 11 and the housing 2 12 to ensure that the ring gear 522 rotates stably under the drive of the worm 524 .

[0033] The present invention provides another embodiment: A method for installing a large-diameter socket-type grooved pipe connector is now proposed, comprising the following steps: Step 1: After the housing 1 11 and the housing 2 12 are connected, they are installed on the outsides of the two pipes 2 in sequence and their positions are adjusted; Step 2: Rotate the drive shaft 521, so that the drive shaft 521 drives the gear 523 to rotate through the meshing connection between the worm 524 and the gear ring 522 and the meshing connection between the gear ring 522 and the gear 523, and the gear 523 drives the internal bidirectional screw 516 to rotate; Step 3: The bidirectional screw rod 516 drives the movable block 515 to lock the position of the docking seat 512 through the push block 517 and the guide block 519, ensuring that the pipe 2 is stably clamped in the movable seat 511; Step 4: The movable block 515 continues to move to push the movable seat 511 to drive the pipe 2 to move into the receiving assembly 4; Step 5: The two pipes 2 are moved into the receiving pipe 41 to squeeze the sealing rings 43 at both ends of the receiving seat 42, so that the sealing rings 43 are deformed to ensure the sealing of the two pipes 2 when they are connected.
