[0002] Heavy-duty petrochemical process pumps refer to pump equipment used in the petrochemical industry that can work stably under harsh conditions such as high temperature, high pressure, strong corrosion, and high viscosity. They are mainly used to transport various petrochemical media, such as crude oil, refined oil, chemical raw materials, and corrosive liquids. Among them, the radially split two-end support BB2 structure is an important structural form in petrochemical process pumps.
[0003] However, existing petrochemical process pumps connect their input and output pipes to external delivery pipes via flanges and multiple bolts. This connection method requires tightening multiple bolts for fixation, which is time-consuming and labor-intensive. Furthermore, the bolt-fixed connection makes disassembly inconvenient. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a heavy-duty petrochemical process pump with a radially split two-end support BB2 structure. This solves the problem that the input and output pipes of the existing petrochemical process pump are connected to the external delivery pipe through flanges and multiple bolts. This connection method requires tightening multiple bolts to fix the connection, which is time-consuming and labor-intensive. Furthermore, the bolt-fixed connection is inconvenient to disassemble.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a radially split, two-end supported BB2 structure heavy-duty petrochemical process pump, including a base, on which a process pump body is fixedly installed, and an input and output pipe is provided on the process pump body. The ports of the input and output pipes are connected to a conveying pipe. A tightening component is also provided on the base, and four limiting sleeves are provided on the tightening component. A pressing component is provided in the middle of each limiting sleeve, and an angle adjusting component is provided at the top of the limiting sleeve.
[0006] Preferably, the tightening assembly includes a support plate, which is fixedly mounted on the base. An adjusting rod is rotatably connected to one side of the top of the support plate, and a limiting rod is fixedly mounted on the other side of the top of the support plate. The adjusting rod is provided with two sets of mirror threads, and the adjusting rod is threadedly connected to one side of four limiting sleeves through the mirror threads. The other side of the limiting sleeve is slidably sleeved on the limiting rod. A first motor is also fixedly mounted on the support plate, and the output end of the first motor is connected to one end of the adjusting rod.
[0007] Preferably, the four limiting sleeves are arranged in pairs, and each pair of limiting sleeves can be fitted onto the outside of the flange of the input / output pipe or the delivery pipe.
[0008] Preferably, the clamping assembly includes a rotating shaft, which is rotatably connected to the middle of the limiting sleeve. A pressure plate and a tail plate are fixedly installed on the outer side of the rotating shaft. A sliding groove is provided on the side of the tail plate. A telescopic drive rod is fixedly installed on the outer side of the limiting sleeve. A U-shaped frame is fixedly connected to the telescopic end of the telescopic drive rod. A sliding column is fixedly installed on the top of the U-shaped frame. The sliding column is slidably connected in the sliding groove.
[0009] Preferably, the top of the pressure plate has a slanted fold structure.
[0010] Preferably, the angle adjustment assembly includes a suspension rod, which is fixedly installed on the top surface of the limiting sleeve. An arc-shaped frame is fixedly installed at the top of the suspension rod. A slide rail is provided inside the arc-shaped frame, and a slide plate is slidably installed on the slide rail.

[0011] Preferably, the suspension rods are located on both sides of the clamping assembly, and the arc-shaped frame has a semi-circular structure.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the setting of tightening components, limiting sleeves, and pressing components, uses a first motor to drive the adjusting rod to rotate. At this time, the two sets of mirror threads rotate the two sets of limiting sleeves respectively, so that the limiting sleeves are fitted on the outside of the flange of the input / output pipe and the conveying pipe. Then, the telescopic drive rod extends, and the sliding column in the U-shaped frame slides along the sliding groove, driving the tail plate to rotate upward, thereby driving the pressure plate to press the flange of the input / output pipe and the conveying pipe together, so that the input / output pipe and the conveying pipe are stably connected and the installation is completed. It can quickly connect and install or disassemble the input / output pipe and the conveying pipe, and is convenient and labor-saving to use.
[0013] This invention uses an angle-adjusting component to mesh and connect the gear with the rack. A second motor drives the worm to rotate, and the worm engages with the worm groove, causing the slide plate to slide along the slide rail. The rack drives the conveying pipe in the gear to rotate, adjusting the angle of the conveying pipe to adapt to the needs of different installation environments. Attached Figure Description

The adjusting rod 52 is provided with two sets of mirror threads 53, and the adjusting rod 52 is threadedly connected to one side of the four limiting sleeves 6 through the mirror threads 53. The other side of the limiting sleeves 6 is slidably sleeved on the limiting rod 55. A first motor 54 is also fixedly mounted on the support plate 51, and the output end of the first motor 54 is connected to one end of the adjusting rod 52.
[0019] Preferably, the four limiting sleeves 6 are arranged in pairs, and each pair of limiting sleeves 6 can be fitted onto the outside of the flange of the input / output pipe 3 and the delivery pipe 4.
[0020] Specifically, the first motor 54 drives the adjusting rod 52 to rotate. At this time, the two sets of mirror threads 53 rotate the two sets of limiting sleeves 6 respectively. Combined with the linear limiting effect of the limiting rod 55, the limiting sleeves 6 move close to each other and are placed on the outside of the flange of the input / output pipe 3 and the conveying pipe 4, so that the conveying pipe 4 can only be adjusted vertically up and down.
[0021] Preferably, the clamping assembly 7 includes a rotating shaft 71, which is rotatably connected to the middle of the limiting sleeve 6. A pressure plate 72 and a tail plate 73 are fixedly installed on the outer side of the rotating shaft 71. A sliding groove 74 is provided on the side of the tail plate 73. A telescopic drive rod 75 is fixedly installed on the outer side of the limiting sleeve 6. A U-shaped frame 76 is fixedly connected to the telescopic end of the telescopic drive rod 75. A sliding column 77 is fixedly installed on the top of the U-shaped frame 76. The sliding column 77 is slidably connected in the sliding groove 74.
[0022] Preferably, the top of the pressure plate 72 has a slanted fold structure.
[0023] Specifically, by extending the telescopic drive rod 75, the sliding column 77 inside the U-shaped frame 76 slides along the sliding groove 74, and drives the tail plate 73 to rotate upward, thereby driving the pressure plate 72 to press the flanges of the input / output pipe 3 and the conveying pipe 4 together, so that the input / output pipe 3 and the conveying pipe 4 are stably connected.
[0024] Preferably, the angle adjustment assembly 8 includes a suspension rod 81, which is fixedly installed on the top surface of the limiting sleeve 6. An arc-shaped frame 82 is fixedly installed at the top of the suspension rod 81. A slide rail 83 is provided inside the arc-shaped frame 82.

[0025] Preferably, the suspension rod 81 is located on both sides of the clamping assembly 7, and the arc frame 82 has a semi-circular structure.
[0026] Specifically, during the process of connecting and installing the input / output pipe 3 and the delivery pipe 4, the gear 810 can be meshed and spliced with the rack 85. Then, the second motor 88 drives the worm 87 to rotate, and the worm 87 meshes with the worm thread 89, causing the slide plate 84 to slide along the slide rail 83. The rack 85 drives the delivery pipe 4 in the gear 810 to rotate, thereby adjusting the installation angle of the delivery pipe 4 to adapt to the needs of different installation environments.
[0027] The working process of this utility model is as follows: During installation, the first motor 54 drives the adjusting rod 52 to rotate. At this time, the two sets of mirror threads 53 rotate the two sets of limiting sleeves 6 respectively, so that the limiting sleeves 6 are fitted on the outside of the flange of the input / output pipe 3 and the conveying pipe 4. Then, the gear 810 is meshed with the rack 85 and spliced together. The second motor 88 drives the worm 87 to rotate, and the worm 87 meshes with the worm thread 89, so that the slide plate 84 slides along the slide rail 83. The rack 85 drives the conveying pipe 4 in the gear 810 to rotate. After adjusting the angle of the conveying pipe 4, the telescopic drive rod 75 extends, and the sliding column 77 in the U-shaped frame 76 slides along the slide groove 74, and drives the tail plate 73 to rotate upward, which in turn drives the pressure plate 72 to press the flange of the input / output pipe 3 and the conveying pipe 4 together, so that the input / output pipe 3 and the conveying pipe 4 are stably connected, and the installation is completed.
