Technical Field

[0001] The utility model belongs to the field of petroleum equipment and relates to a blowout preventer, in particular to a lifting test device for the blowout preventer. Background Art

[0002] BOP is a sealed wellhead safety device commonly used in oil fields to prevent blowouts. It is a vital well control device in drilling operations. BOPs are mainly divided into two types: gate blowout preventers and annular blowout preventers. BOPs need to undergo load tests before leaving the factory, and the load tests require 1.5 times the test. When using it, it is also necessary to conduct a hoisting test on site to simulate the hoisting work, check its bearing capacity and stability, and ensure that the BOP will not be deformed or damaged during the hoisting process.

[0003] When the blowout preventer is hoisted for testing on site, the hoisting positions are different for different types of blowout preventers, so the test device needs to be adapted to different blowout preventers. However, the traditional test device has a single structure and needs to use different test devices for different types of blowout preventers. In addition, it is inconvenient to assemble on site and is time-consuming and labor-intensive to use, which greatly reduces the test efficiency. Utility Model Content

[0004] The utility model is to solve the technical problem that the test device cannot adapt to different blowout preventers and the on-site assembly is inconvenient, and provides a lifting test device for a blowout preventer. By designing a crossbeam assembly with multiple horizontal installation positions to adapt to blowout preventers of different radial specifications, and a hanging plate with multiple vertical lifting holes to adapt to blowout preventers of different heights, the adaptability of the lifting device is improved, and it is flexible and simple to use.

[0005] The technical solution adopted by the utility model is: to provide a lifting test device for a blowout preventer, comprising a clamping ring adapted to the blowout preventer, with lifting ears symmetrically arranged on both sides of the clamping ring, the clamping ring is arranged on a lifting device, two hanging plates are symmetrically arranged on both sides of the lifting device, lifting holes are arranged at the bottom of the two hanging plates, and adjustment hole groups are vertically arranged on the hanging plates above the lifting holes; the lifting ears are hoisted and matched with the lifting holes; the output end of the lifting device is equipped with a beam assembly, two groups of installation stations are arranged horizontally along the beam assembly, the two groups of installation stations are symmetrically distributed on both sides of the lifting device, and a pair of symmetrical installation stations in the two groups of installation stations are detachably installed with a pair of symmetrical adjustment holes in the two hanging plates respectively.

[0006] The clamping ring adapted to the blowout preventer is adapted with different clamping rings according to the specifications of the blowout preventer, so that the clamping ring can lock the blowout preventer firmly and reliably, the hanging plate is connected with the lifting ring on the clamping ring, the lifting device is placed on the upper end surface of the blowout preventer, the adjusting hole on the hanging plate is connected with the installation station on the beam assembly, and the large number of adjusting holes and installation stations makes the position adjustment of the hanging plate diverse so as to adapt to different lifting equipment and improve the adaptability of use, and when the hydraulic cylinder drives the beam assembly to move upward, the hanging plate lifts the clamping ring through the lifting ear to apply an external force load to the blowout preventer to verify the mechanical performance and stability of the blowout preventer, which is easy to operate, flexible and efficient to use.

[0007] To further optimize the technical solution, the lifting device is a hydraulic cylinder, and the output end of the hydraulic cylinder is assembled with the crossbeam assembly.

[0008] The hydraulic cylinder drives the crossbeam assembly to move up and down stably and reliably.

[0009] To further optimize the technical solution, the clamping ring includes two arc-shaped docking pieces, the docking pieces are assembled with the help of connecting pads, and the lifting ears are detachably mounted on the connecting pads.

[0010] The two detachable docking parts are convenient for assembly with the blowout preventer and are locked with the help of connecting pads, which makes on-site assembly convenient, labor-saving and simple to operate. The connecting pads are used to connect the lifting ears, provide installation positions, ensure the lifting strength of the lifting ears, and improve reliability.

[0011] To further optimize the technical solution, the beam assembly includes two beam bodies arranged front and back, the two beam bodies are assembled with the help of connecting parts, the two beam bodies are assembled with the output end of the hydraulic cylinder with the help of assembly parts, and the installation station is set on the two beam bodies.

[0012] The front-to-back distributed crossbeam body sandwiches the output ends of the hanging plate and the hydraulic cylinder in the middle, thereby preventing the output ends of the hanging plate and the hydraulic cylinder from being separated from the crossbeam body, thereby improving the stability and reliability of use.

[0013] To further optimize the technical solution, the connecting parts include a plurality of bolts arranged between the two beam bodies, the side walls of the bolts are sleeved with spacers, the two ends of the spacers are respectively abutted against the outer walls of the beam bodies, and both ends of the bolts pass through the beam bodies and are threadedly connected with nuts, which are abutted against the outer walls of the beam bodies.

[0014] The bolts penetrate the front and rear distributed beam bodies, and as the nuts are tightened and fixed, the spacers sleeved on the outer walls of the bolts abut against the outer walls of the beam bodies respectively, so that the beam bodies are kept spaced apart, without interfering with the assembly of the hanging plates and the operation of the hydraulic cylinders, and are flexible and reliable to use.

[0015] To further optimize the technical solution, the assembly includes a fisheye joint coaxially assembled with the output end of the hydraulic cylinder, a kingpin shaft is pinned inside the fisheye joint, the diameters of both ends of the kingpin shaft are smaller than the middle diameter, and the two ends of the kingpin shaft are respectively pinned to the crossbeam body.

[0016] After the kingpin shaft passes through the fisheye joint, its two ends are pinned to the outer wall of the beam body respectively. The diameters of the two ends of the kingpin shaft are smaller than the diameter of the middle section. After it is pinned to the beam body, as the diameter of the kingpin shaft increases, the crossbeam bodies are restricted from approaching each other so that they maintain a distance. After the crossbeam body is locked and fixed, the crossbeam body constrains the position of the kingpin shaft to avoid separation. It is easy to assemble and reliable to use.

[0017] To further optimize the technical solution, the installation station includes installation holes arranged on the two beam bodies and support members arranged between the two beam bodies, the positions and numbers of the installation holes on each beam body correspond, and the support members and the installation holes are detachably installed.

[0018] The beam body is assembled with the hanging plate through a connecting piece. The connecting piece is arranged between the two beam bodies and assembled with the mounting holes on the beam body, so that the installation position can be adjusted conveniently, making the on-site assembly test operation simple, flexible and labor-saving.

[0019] To further optimize the technical solution, the support member includes a side pin shaft, which is pin-connected to the mounting hole on the beam body and is connected to a locking member.

[0020] The hanging plate is inserted between the beam bodies, and after the adjustment hole and the mounting hole are aligned, the side pin passes through the adjustment hole and the mounting hole, and the hanging plate is assembled on the beam body. The operation is simple, and the locking piece locks the position of the side pin to prevent the hanging plate from falling off, thereby ensuring safe use.

[0021] To further optimize the technical solution, the locking member includes a gland bolt threadedly connected to the side pin shaft and a gland matched with the gland bolt, and the gland abuts against the outer wall of the beam body.

[0022] With the threaded connection between the gland bolt and the side pin, the gland is pushed to abut against the side wall of the beam body, thereby constraining the side pin between the beam bodies, preventing the side pin from detaching from the beam body, and ensuring the reliability of the hanging plate test operation.

[0023] The beneficial effects of the utility model are:

[0024] 1. The crossbeam assembly with multiple horizontal installation positions is designed to adapt to BOPs of different radial specifications, and the hanging plate with multiple vertical lifting holes is designed to adapt to BOPs of different heights, thereby improving the adaptability of the lifting device and making it flexible and easy to use. The assembleable structure of the clamp ring is convenient for connecting with the BOP and for applying external force load to the BOP when the hanging plate pulls the lifting lug, thereby verifying the mechanical performance and stability of the BOP, and is easy to operate.

[0025] 2. After the bolt passes through the beam, as the nut engages with it and locks it, the beam body is pushed to abut against the spacer sleeve on the outer wall of the bolt. The spacer sleeve supports the beam body to keep the interval, avoids interference with the assembly of the hanging plate and the beam body, and ensures the reliability of operation. It is easy to assemble, flexible and efficient to use;

[0026] 3. When the hanging plate is assembled with the beam body, after the adjustment hole and the mounting hole are overlapped, the side pin shaft passes through the adjustment hole and the mounting hole, and is threadedly connected with the gland bolt. The gland bolt pushes the gland to move, and after it abuts against the outer wall of the beam body, the position of the side pin shaft is constrained. After the gland bolt is tightened, the firmness of the side pin shaft assembly is improved to ensure the safety of the hanging plate;

[0027] 4. After the kingpin shaft is plugged into the fisheye joint at the output end of the hydraulic cylinder, the two ends of the kingpin shaft are pinned to the beam body respectively. The diameters of the two ends of the kingpin shaft are smaller than the diameter of the middle section. Therefore, the kingpin shaft constrains the interval of the beam body, and after the beam body is locked, the position of the kingpin shaft is not constrained, and it is prevented from detaching from the beam body. The assembly is simple, and the use is stable and reliable.

[0028] 5. When the hanging plate is connected to the lifting lug for the lifting test, if the hanging plate is disconnected from the blowout preventer for some reason, as the hydraulic cylinder continues to operate, the beam body deflects along the main pin axis, and the hanging plate that is not disconnected from the blowout preventer deflects along the side pin axis to remove the external force load of the hydraulic cylinder and improve safety in use.

DETAILED DESCRIPTION

[0038] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Please see attached Figure 1 A lifting test device for a blowout preventer comprises a clamping ring 1 adapted to the blowout preventer. Different clamping rings 1 are adapted according to the specifications of the blowout preventer, so that the clamping ring 1 can lock the blowout preventer firmly and reliably. The clamping ring 1 comprises two arc-shaped butt joints 101. When the clamping ring 1 is assembled on the blowout preventer, the butt joints 101 are split so as to respectively abut against the outer wall of the blowout preventer, and the butt joints 101 are assembled with the help of connecting pads 102. The butt joints 101 and the connecting pads 102 are connected and locked with the help of bolts, etc. Two lifting ears 4 are symmetrically arranged on both sides of the clamping ring 1. The lifting ears 4 can be detachably installed on the connecting pads 102, and the connecting pads 102 are assembled with the lifting ears 4 by setting an assembly port, and a plurality of assembly ports can be set so as to adjust the position of the lifting ears 4 and improve its adaptability in use;

[0040] Please see attached Figure 1-7, the clamp ring 1 is arranged on the lifting device, the output end of the lifting device is equipped with a beam assembly, the lifting device is a hydraulic cylinder 2, and its output end is assembled with the beam assembly, which is stable and reliable to use. The beam assembly includes two beam bodies 5 arranged in front and behind, and the beam bodies 5 are assembled with the help of connecting parts. The connecting parts are multiple bolts 6 arranged between the two beam bodies 5. The side walls of the bolts 6 are all sleeved with spacers 601, and the two ends of the spacers 601 are respectively abutted against the outer walls of the beam bodies 5. The spacers 601 constrain the positions of the two beam bodies 5 to keep them spaced, and both ends of the bolts 6 pass through the beam body 5 and are threadedly connected with nuts 602. The nuts 60 2 is abutted against the outer wall of the beam body 5, and the beam body 5 is locked. The beam body 5 is assembled with the output end of the hydraulic cylinder 2 by means of an assembly part. The assembly part includes a fisheye joint 7 coaxially assembled with the output end of the hydraulic cylinder 2. A main pin shaft 701 is pinned inside the fisheye joint 7. The diameters of both ends of the main pin shaft 701 are smaller than the diameter of the middle part. Both ends of the main pin shaft 701 are pinned with the beam body 5 respectively, and the beam body 5 is kept spaced. After the beam body 5 is locked by the bolt 6 and the nut 602, the two beam bodies 5 clamp the main pin shaft 701 to prevent it from falling off, which is easy to assemble and improves the stability and reliability of the use of the hydraulic cylinder 2 and the beam assembly;

[0041] Please see attached Figure 1 , Attachment Figure 5 Two hanging plates 3 are symmetrically arranged on both sides of the lifting device, and hanging holes 302 are arranged at the bottom of the two hanging plates. The hanging holes 302 are hoisted and matched with the lifting ears 4. A group of adjustment holes 301 are arranged vertically on the hanging plates above the hanging holes. Two groups of installation stations are arranged horizontally along the beam assembly. The two groups of installation stations are symmetrically distributed on both sides of the lifting device, and a pair of symmetrical installation stations in the two groups of installation stations are detachably installed with a pair of symmetrical adjustment holes 301 in the two hanging plates. The large number of installation stations and adjustment holes 301 makes the position adjustment of the hanging plate 3 diverse, so as to adapt to different lifting equipment and improve the adaptability of use;

[0042] Please see attached Figure 1 , Attachment Figure 8The installation station includes mounting holes 501 arranged on the two beam bodies 5 and a support member arranged between the two beam bodies 5. The positions and numbers of the mounting holes (501) on each beam body (5) correspond, and the support member and the mounting hole (501) are detachably installed. The support member is a side pin shaft 8, and the side pin shaft 8 is pinned to the mounting hole 501 on the beam body 5 and is connected with a locking member. The locking member locks the side pin shaft 8 and installs it on the beam body 5. The locking member includes a pressure cap bolt 801 threadedly connected to the side pin shaft 8 and a pressure cap 802 matched with the pressure cap bolt 801. As the pressure cap bolt 801 is tightened on the side pin shaft 8, the pressure cap 802 is pushed to abut against the outer wall of the beam body 5, thereby fixing the position of the side pin shaft 8, preventing the side pin shaft 8 from slipping out of the mounting hole 501, improving the firmness and reliability of the assembly of the side pin shaft 8, and improving the safety of the assembly and use of the hanger plate 3;

[0043] The working principle of the lifting test device for blowout preventer is as follows: the clamping ring 1 adapted to the blowout preventer can be split into two docking pieces 101, which are convenient for assembly with the blowout preventer. The docking pieces 101 are connected to each other by means of a connecting pad 102. After being assembled into a complete clamping ring 1, they are connected and locked with the blowout preventer. After the lifting lug 4 passes through the lifting hole 302 on the hanging plate 3, the lifting lug 4 is connected to the connecting pad 102. The hydraulic cylinder 2 is placed on the upper end surface of the blowout preventer, and after the main pin shaft 701 is plugged with the fisheye joint 7 at the output end of the hydraulic cylinder 2, the crossbeam body 5 is pinned with the main pin shaft 701, and the bolt 6 is placed between the two crossbeam bodies 5. After the nut 602 is tightened along the bolt 6, the crossbeam body 5 is pushed to abut against the spacer 601, so that the crossbeam body 5 maintains a gap and does not interfere with the generation of the hanging plate 3. The diameters of the two ends of the main pin shaft 701 are smaller than the diameter of the middle section, so that the crossbeam body 5 constrains the position of the main pin shaft 701, thereby improving the stability and reliability of the assembly and use of the crossbeam assembly and the hydraulic cylinder 2.

[0044] By inserting the hanging plate 3 between the beam bodies 5 and making the adjustment hole 301 at the appropriate position on the hanging plate 3 coincide with the mounting hole 501 at the appropriate position on the beam body 5, the side pin shaft 8 is pinned with the adjustment hole 301 and the mounting hole 501, so as to connect the hanging plate 3 with the beam body 5, and the gland bolt 801 is threadedly connected with the side pin shaft 8, and after being tightened, the gland 802 is pushed to abut against the outer wall of the beam body 5, so as to constrain the position of the side pin shaft 8, which is easy to assemble and ensures the safety and stability of use;

[0045] When the hydraulic cylinder 2 drives the crossbeam body 5 to move upward, the hanging plate 3 pulls the lifting lug 4 through the hanging plate 3, thereby applying an external force load to the blowout preventer to verify the mechanical performance and stability of the blowout preventer. The operation is simple, and after the hanging plate 3 on one side is disconnected from the lifting lug 4, as the hydraulic cylinder 2 drives the crossbeam assembly to continue to move, the crossbeam body 5 deflects along the output end of the hydraulic cylinder 2, and the hanging plate 3 connected to the lifting lug 4 deflects along the side pin 8, stopping the hydraulic cylinder 2 from applying an external force load to the blowout preventer, so that the hydraulic cylinder 2 can be stopped in time to ensure the safety of the test.
