Description

Technical Field

[0001] This invention relates to the field of gate disassembly technology, and more particularly to a blowout preventer gate disassembly device. Background Technology

[0002] Gate blowout preventers are an important piece of equipment used in the drilling process. In the process of repairing and inspecting gate blowout preventers, it is very important to ensure the quality of repair and inspection, and to standardize the repair and inspection content, procedures and quality control measures. During the repair of gate blowout preventers, it is necessary to replace the rubber core assembly of the gate.

[0003] Among them, the gate 1-1 is provided with a first slot 11-1 and a second slot 12-1 (as shown in the attached diagram). Figure 3 As shown), the core assembly 2-1 includes a first core 21-1 and a second core 22-1, and the first core 21-1 is composed of a first core body 211-1 and a first core pin 212-1 (as shown in the attached figure). Figure 2 As shown in the attached diagram, generally, the first adhesive core 21-1 is embedded in the first slot 11-1, and the second adhesive core 22-1 is embedded in the second slot 12-1 (as shown in the attached diagram). Figure 1 As shown in the diagram, the first rubber core 21-1, the second rubber core 22-1, and the gate 1-1, when used together, can be used as a blowout preventer during drilling. After a period of use, the first rubber core 21-1 and the second rubber core 22-1 need to be replaced. At this time, the first rubber core 21-1 and the second rubber core 22-1 need to be removed from the first slot 11-1 and the second slot 12-1, respectively. In traditional related technologies, the first rubber core 21-1 is usually removed by manual tapping and prying. The process of replacing the second rubber core 22-1 is time-consuming, labor-intensive, and inefficient. Currently, there is no mature dedicated replacement equipment for the rubber core assembly 2-1 on the gate 1-1 in domestic and foreign oil drilling equipment companies. The main method for replacing the rubber core assembly 2-1 on the gate 1-1 is for maintenance workers to use punches, screwdrivers, hammers, and bench vises to disassemble the blowout preventer rubber core assembly 2-1. The disassembly process is time-consuming and labor-intensive, and it is easy to damage other parts of the gate 1-1, affecting the sealing performance of the gate 1-1. In some cases, the gate 1-1 with poor sealing may even be scrapped.

[0004] Therefore, in order to ensure the quality of gate valve core replacement, guarantee its reliable sealing performance, improve maintenance efficiency, and reduce labor intensity, we propose a new blowout preventer gate valve disassembly device to solve the above-mentioned technical problems.

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0056] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0057] Please see Figures 1 to 14 The present invention provides a blowout preventer gate disassembly device, which includes an operating platform 1, a first rubber core disassembly mechanism 2, a first rubber core pin disassembly mechanism 3, a second rubber core disassembly mechanism 4, and a running mechanism 5.

[0058] In an embodiment of the present invention, please refer to Figure 4The operating table 1 is equipped with a first glue core removal mechanism 2, a first glue core pin removal mechanism 3, and a second glue core removal mechanism 4. The first glue core removal mechanism 2 and the second glue core removal mechanism 4 are located on both sides of the operating table 1, and the first glue core pin removal mechanism 3 is located between the first glue core removal mechanism 2 and the second glue core removal mechanism 4.

[0059] In this application, the gate 1-1 is moved to the first rubber core disassembly mechanism 2 by the operating mechanism 5, and then the first rubber core 21-1 is disassembled by the first rubber core disassembly mechanism 2.

[0060] If the first core removal mechanism 2 only removes the first core body 211-1, while the first core pin 212-1 is still inserted on the gate 1-1, then the first core pin removal mechanism 3 removes the first core pin 212-1.

[0061] If the first rubber core removal mechanism 2 completely removes the first rubber core 21-1 from the gate plate 1-1, the first rubber core pin removal mechanism 3 is not required.

[0062] After the first rubber core 21-1 is removed, the operating mechanism 5 is used to move the gate 1-1 to the second rubber core removal mechanism 4, and then the second rubber core 22-1 is removed by the second rubber core removal mechanism 4. Then the operating mechanism 5 is used to move the gate 1-1 away from the operating table 1.

[0063] In an embodiment of the present invention, please refer to Figure 4 and Figure 14 The blowout preventer gate disassembly device also includes a running mechanism 5, and the running mechanism 5 includes a crane bracket 51. The crane bracket 51 is located on one side of the operating platform 1, and a rail connecting plate 52 is fixedly installed on the crane bracket 51. A crane rail 53 is fixedly installed on the rail connecting plate 52, and a slidingly connected electric crane 54 is installed on the crane rail 53.

[0064] It should be noted that when removing the rubber core assembly 2-1 from the gate plate 1-1, the gate plate 1-1 is lifted by an electric crane 54, so that the gate plate 1-1 can be moved on the first rubber core removal mechanism 2, the first rubber core pin removal mechanism 3, or the second rubber core removal mechanism 4. This eliminates the need for manual handling, improves work efficiency, and enhances the safety of transferring the gate plate 1-1.

[0065] In an embodiment of the present invention, please refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 7The first rubber core removal mechanism 2 includes a positioning clamping component 21 for clamping and fixing the gate plate. The positioning clamping component 21 includes a displacement component 211, a centering positioning component 212, and a Z-axis positioning component 213. The centering positioning component 212 is provided in two sets and located on both sides of the displacement component 211. The Z-axis positioning component 213 is located at the end of the displacement component 211. The displacement component 211, the centering positioning component 212, and the Z-axis positioning component 213 are used to limit the front-back, left-right, and up-down displacement of the gate plate, thereby improving the stability of the first rubber core removal mechanism 2 when removing the first rubber core 21-1 from the gate plate 1-1.

[0066] In an embodiment of the present invention, please refer to Figure 5 and Figure 7 The displacement component 211 includes a moving track 2110, which is fixedly installed on the operating table 1. A front limit plate 2112 and a rear limit plate 2118 are fixedly installed at the front and rear ends of the moving track 2110, respectively. A rotatably connected lead screw A2113 is installed inside the moving track 2110. A threaded lead screw support A2114 is sleeved on the lead screw A2113. A support A mounting plate 2115 is fixedly installed on the lead screw support A2114 by bolts. A sliding block 2116 is fixedly installed on the support A mounting plate 2115 by bolts. A T-block 2117 is fixedly installed on the sliding block 2116 by bolts.

[0067] The two ends of the lead screw A2113 are rotatably connected to the front limit plate 2112 and the rear limit plate 2118 respectively, and the front limit plate 2112 is equipped with a handwheel A2111 for driving the lead screw A2113 to rotate.

[0068] It should be noted that when the operating mechanism 5 transports the gate 1-1 above the T-block 2117, after aligning the T-slot of the gate 1-1 with the T-block 2117, the gate 1-1 falls onto the moving track 2110. Then, the handwheel A2111 is turned to drive the lead screw A2113 to rotate, so the gate 1-1 will move back and forth on the moving track 2110. When the first rubber core 21-1 is removed, due to the cooperation between the T-slot of the gate 1-1 and the T-block 2117, the front and back positions of the gate 1-1 will not change when the handwheel A2111 is not rotated.

[0069] In this embodiment, the T-block 2117 is provided with a variety of different sizes of structures. The T-block 2117 of a matching size is selected and installed according to the different sizes of the gate 1-1.

[0070] Among them, the two side plates of the mounting plate 2115 of support A are respectively inserted into the side sliding grooves in the moving rail 2110 and slidably connected to the side sliding grooves, thereby avoiding the potential risk of the mounting plate 2115 of support A deflecting when the lead screw A2113 rotates.

[0071] In an embodiment of the present invention, please refer to Figure 5 and Figure 6 The centering and positioning component 212 includes a centering and positioning wedge slider 2121 and a centering and positioning base 2122. The centering and positioning base 2122 is fixed to the operating table 1 on one side of the moving track 2110 by bolts, and a dovetail groove is provided on the centering and positioning base 2122. The bottom insertion end of the centering and positioning wedge slider 2121 is inserted into the dovetail groove of the centering and positioning base 2122 and is slidably connected to the dovetail groove. Both the centering and positioning wedge slider 2121 and the centering and positioning base 2122 have positioning threaded holes. By screwing bolts into the positioning threaded holes, the fixed position of the centering and positioning wedge slider 2121 on the centering and positioning base 2122 can be locked.

[0072] It should be noted that after the gate 1-1 is placed on the displacement component 211 and its front and back positions are adjusted, the four centering and positioning wedge sliders 2121 on the left and right sides are slid to make the gate 1-1 have no angle relative to the displacement component 211 and be centered left and right. Then, the bolts are screwed into the positioning holes of the centering and positioning wedge sliders 2121 and the center positioning base 2122 to complete the restriction of the left and right position of the gate 1-1.

[0073] Therefore, the designed centering and positioning component 212 ensures that the gate 1-1 does not have angular or lateral displacement relative to the front displacement component 211 during the process of disassembling the first rubber core 21-1, thus avoiding angular or lateral displacement between the gate 1-1 and the displacement component 211 due to the disassembly force during the process of disassembling the first rubber core 21-1.

[0074] In an embodiment of the present invention, please refer to Figure 5 and Figure 6 The Z-axis positioning assembly 213 includes a support B2131, which is fixedly mounted on the operating table 1 near the end of the moving track 2110 by bolts. A rotating shaft 2132 is mounted on the support B2131, and a rotating arm A2133 is fixedly mounted on the rotating shaft 2132. A threaded through hole is opened on the rotating arm A2133, and a threaded limit rod 2134 is inserted into the threaded through hole. A handwheel B2135 is fixedly mounted on the upper end of the threaded limit rod 2134.

[0075] It should be noted that after the gate 1-1 is placed on the displacement component 211 and its front and rear positions are adjusted, and it is centered and positioned by the centering and positioning component 212, the rotating arm A2133 is rotated to be directly above the gate 1-1, and then the handwheel B2135 is turned to drive the threaded limit rod 2134 to move downward until the threaded limit rod 2134 is tightly pressed onto the gate 1-1, which can limit the upward displacement of the gate 1-1.

[0076] Therefore, the designed Z-axis positioning component 213 effectively restricts the risk of upward displacement of the gate 1-1, and eliminates the risk that the gate 1-1 will leave the operating table 1 due to the upward pushing force of the disassembly force on the gate 1-1 during the disassembly of the first rubber core 21-1.

[0077] It is worth noting that since the centering and positioning component 212 has a certain clamping force on the gate 1-1, when the clamping force of the centering and positioning component 212 on the gate 1-1 is sufficient, the Z-axis positioning component 213 may not be needed. Therefore, whether the Z-axis positioning component 213 can position the gate 1-1 in the Z-axis direction is to be selected by the technicians according to the actual situation.

[0078] In an embodiment of the present invention, please refer to Figure 5 and Figure 6 The first adhesive core removal mechanism 2 also includes a removal execution component 22 for removing the first adhesive core. The removal execution component 22 includes a first adhesive core removal blade 2205 for removing the first adhesive core, a pushing hydraulic cylinder 2210 for driving the blade of the first adhesive core removal blade 2205 to insert into the removal surface of the first adhesive core, and a lifting hydraulic cylinder 2201 for driving the first adhesive core removal blade 2205 to apply an upward pushing force to the first adhesive core. Specifically:

[0079] The disassembly execution component 22 also includes a fixing plate 2203, which is fixedly mounted on the operating table 1 by bolts. A hydraulic cylinder mounting base A2202 is fixedly mounted on the bottom of the fixing plate 2203. A lifting hydraulic cylinder 2201 is fixedly mounted on the hydraulic cylinder mounting base A2202, and a lifting shaft 2204 is fixedly mounted on the output end of the lifting hydraulic cylinder 2201. A first rubber core disassembly knife holder 2211 is rotatably connected to the lifting shaft 2204. A pushing hydraulic cylinder 2210 is fixedly mounted on the first rubber core disassembly knife holder 2211, and a guide block 2209 is fixedly mounted on the output end of the pushing hydraulic cylinder 2210. The first rubber core disassembly knife is inserted into the guide block 2209. The first glue core removal tool holder 2208 is slidably connected to the first glue core removal tool holder 2211 inside the base 2211, and the end of the guide block 2209 is fixedly installed with the first glue core removal tool holder 2208 by bolts. A sliding pressure block hydraulic cylinder 2207 is fixedly installed on the first glue core removal tool holder 2208, and a sliding pressure block 2206 is fixedly installed at the output end of the sliding pressure block hydraulic cylinder 2207. The first glue core removal tool 2205 is inserted into the mating groove opened in the first glue core removal tool holder 2208 and fixed by bolts. The sliding pressure block 2206 slides up and down in the first glue core removal tool holder 2208 through the sliding pressure block hydraulic cylinder 2207, and the sliding pressure block 2206 is located above the first glue core removal tool 2205.

[0080] In this application, the specific operation steps for disassembling the first adhesive core 21-1 by disassembling the disassembly actuator 22 are as follows:

[0081] Step 1: After the positioning and clamping component 21 positions and clamps the gate 1-1, start the lifting hydraulic cylinder 2201 to move up and down, so that the blade of the first rubber core removal knife 2205 is at the same horizontal plane as the removal surface of the first rubber core 21-1.

[0082] Step 2: Rotate and adjust the direction of the first glue core removal knife holder 2211 so that the first glue core removal knife 2205 can be inserted into the removal surface of the first glue core 21-1;

[0083] Step 3: Operate the hydraulic cylinder 2210 to insert the blade of the first rubber core removal knife 2205 into the removal surface of the first rubber core 21-1. At the same time as the blade of the first rubber core removal knife 2205 is inserted into the removal surface of the first rubber core 21-1, start the sliding pressure block hydraulic cylinder 2207 to drive the sliding pressure block 2206 to press the first rubber core 21-1 downward.

[0084] Step 4: Restart the lifting hydraulic cylinder 2201 to move upward. At this time, the first rubber core removal knife 2205 applies an upward thrust to the first rubber core 21-1, while the gate plate 1-1 is fixed on the operating table 1. The first rubber core 21-1 is removed from the gate plate 1-1 under the upward thrust of the first rubber core removal knife 2205.

[0085] It is worth noting that during the upward movement of the lifting hydraulic cylinder 2201, the sliding pressure block hydraulic cylinder 2207 always drives the sliding pressure block 2206 to press the first rubber core 21-1 downward.

[0086] In an embodiment of the present invention, please refer to Figure 4 , Figure 9 as well as Figure 10 The first core pin removal mechanism 3 includes a pin-pulling blade 309 for pulling out the first core pin, a pneumatic hammer 307 for impacting the first core pin, and a cylinder 304 for driving the pin-pulling blade 309 to rise and fall. Specifically:

[0087] The first rubber core pin disassembly mechanism 3 also includes a support frame 301, which is fixedly installed on the operating table 1 by bolts. A rotating shaft 303 is fixedly installed on the support frame 301, a rotating arm B302 is fixedly installed on the rotating shaft 303, a lifting cylinder 304 is fixedly installed on the rotating arm B302, and a hoisting bracket 305 is fixedly installed at the output end of the lifting cylinder 304. A mounting frame 306 is installed on the hoisting bracket 305, and a pneumatic hammer 307 is fixedly installed inside the mounting frame 306. A pin-pulling chain 308 is fixedly installed at the bottom of the mounting frame 306, and a pin-pulling plate 309 is installed on the pin-pulling chain 308. The pin-pulling plate 309 has an oblique hole. An operating button 310 for controlling the cylinder 304 and the pneumatic hammer 307 is fixedly installed on the support frame 301.

[0088] It should be noted that when disassembling the first rubber core 21-1, some first rubber cores 21-1 can be easily disassembled by the first rubber core disassembly mechanism 2. However, due to long-term use, the first rubber core pin 212-1 of some first rubber cores 21-1 has rusted and is tightly inserted into the first rubber core positioning hole on the gate plate 1-1. Therefore, the first rubber core disassembly mechanism 2 can only remove the first rubber core body 211-1, while the first rubber core pin 212-1 remains inserted into the gate plate 1-1. At this time, the first rubber core pin disassembly actuator 3 can remove the first rubber core pin 212-1 from the gate plate 1-1.

[0089] In this application, the specific operating steps for the first adhesive core pin disassembly mechanism 3 to disassemble the first adhesive core pin 212-1 are as follows:

[0090] Step 1: When the gate 1-1 removes the first rubber core 211-1 from the gate 1-1 through the first rubber core removal mechanism 2, while the first rubber core pin 212-1 is still on the gate 1-1, adjust the rotating arm B302 so that the pin-pulling piece 309 is located directly above the first rubber core pin 212-1.

[0091] Step 2: Start the cylinder 304 by operating button 310 to drive the pin puller 309 to move downward. When the oblique hole on the pin puller 309 can be aligned with the first rubber core pin 212-1, close the cylinder 304 and then insert the first rubber core pin 212-1 into the oblique hole on the pin puller 309.

[0092] Step 3: Start the cylinder 304 to drive the pin-pulling piece 309 to move upward, so that the pin-pulling piece 309 has an upward pulling force on the first rubber core pin 212-1. At the same time, start the pneumatic hammer 307, and the pneumatic hammer 307 has an upward impact force on the first rubber core pin 212-1 through the pin-pulling piece 309. Combined with the upward pulling force of the cylinder 304, the first rubber core pin 212-1 is removed from the gate 1-1.

[0093] In this application, the hole on the pull pin 309 is an oblique hole, so that when the first core pin 212-1 is pulled upward, the first core pin 212-1 is not easily dislodged from the pull pin 309.

[0094] The pin-pulling chain 308 is a flexible structure, which allows the pin-pulling piece 309 to move up and down and rotate relative to the mounting frame 306. Therefore, when the first core pin 212-1 is inserted into the inclined hole on the pin-pulling piece 309, the pin-pulling piece 309 can be adjusted to a position near the first core pin 212-1 without being too precise. Then, by adjusting the pin-pulling piece 309, the first core pin 212-1 can be easily inserted into the inclined hole on the pin-pulling piece 309.

[0095] In an embodiment of the present invention, please refer to Figure 4 ,Figure 11 , Figure 12 and Figure 13 The second rubber core disassembly mechanism 4 includes a transverse component 41 for driving the gate to move. The transverse component 41 includes a sliding rail 4101. The sliding rail 4101 is fixedly installed on the operating table 1 by bolts. A front limit frame 4102 and a rear limit frame 4103 are fixedly installed on the front and rear ends of the sliding rail 4101. A driving hydraulic cylinder 4104 is fixedly installed in the sliding rail 4101 by a frame. A track slide plate connecting frame 4105 is fixedly installed at the output end of the driving hydraulic cylinder 4104. A track slide plate 4106 is fixedly installed on the track slide plate connecting frame 4105. A T-shaped seat 4107 is fixedly installed on the track slide plate 4106. The two side edges of the track slide plate 4106 are respectively inserted into the sliding grooves provided in the sliding rail 4101 and slidably connected to the sliding grooves.

[0096] A threaded push column 4109 with threaded connection is inserted into the threaded through hole on the front limit frame 4102. A rotating handle 4108 is fixedly installed at one end of the threaded push column 4109, and a rotatably connected limit pressing plate 4110 is installed at the other end of the threaded push column 4109. The two sides of the limit pressing plate 4110 are respectively inserted into the sliding groove in the sliding rail 4101 and slidably connected to the sliding groove.

[0097] The second rubber core removal mechanism 4 also includes an insertion assembly 42 for removing the second rubber core. Two sets of insertion assemblies 42 are provided and are respectively located on both sides of the transverse assembly 41. The insertion assembly 42 includes a second rubber core removal blade 4203 and a second rubber core hydraulic cylinder 4204 for driving the second rubber core removal blade 4203 to insert into the second rubber core removal surface. Specifically:

[0098] The cutting assembly 42 also includes a second glue core cutter holder 4201, which is fixedly mounted on the operating table 1 on one side of the sliding rail 4101 by bolts. A second glue core cutter holder 4202 is slidably connected inside the second glue core cutter holder 4201. A second glue core removal cutter 4203 is fixedly mounted on the second glue core cutter holder 4202 by bolts. A second glue core hydraulic cylinder 4204 is fixedly mounted on the operating table 1 by a hydraulic cylinder mounting seat B4205.

[0099] In this application, the specific operating steps for the second adhesive core removal mechanism 4 to remove the second adhesive core 22-1 are as follows:

[0100] Step 1: After the first rubber core 21-1 is disassembled, the operating mechanism 5 is used to move the gate 1-1 to the T-shaped seat 4107 in the second rubber core disassembly mechanism 4. After aligning and cooperating the T-shaped groove on the gate 1-1 and the T-shaped seat 4107, the gate 1-1 falls on the sliding track 4101.

[0101] Step 2: Activate the drive hydraulic cylinder 4104 to move the gate 1-1 on the sliding rail 4101. When the second core removal blade of the cutting assembly 42 is aligned with the mating surface of the second core 22-1 and the gate 1-1, close the drive hydraulic cylinder 4104. Then rotate the handle 4108 to push the threaded push column 4109 to push the limit pressing plate 4110 to press against the gate 1-1. At this time, the front and rear displacement of the gate 1-1 is adjusted.

[0102] Step 3: When the second core removal knife 4203 of the cutting assembly 42 is inserted into the removal surface of the second core 22-1, and when the blade of the second core removal knife 4203 is close to the mating surface of the second core 22-1, the second core hydraulic cylinder 4204 is activated so that the blade of the second core removal knife 4203 is inserted into the mating surface of the second core 22-1 and the gate 1-1.

[0103] Step 4: Start the hydraulic cylinder 4104 to drive the gate 1-1 to move backward, while the second rubber core removal knife 4203 restricts the second rubber core 22-1 to move backward. The second rubber core is removed by the joint cooperation of the transverse component 41 and the infeed component 42.

[0104] In this application, the positioning and clamping component 21 achieves three-dimensional precise fixation of the gate 1-1 through the displacement component 211, the centering and positioning component 212, and the Z-axis positioning component 213. The lifting hydraulic cylinder 2201 provides vertical thrust, pushing the hydraulic cylinder 2210 to control the first rubber core removal knife 2205 to insert into the rubber core gap. The sliding pressure block 2206 presses down synchronously to prevent deviation and avoid damage caused by manual prying. For the rusted pin 212, a combination of pneumatic hammer 307 and pin pulling piece 309 is designed to punch the first rubber core pin 212-1. The combined disassembly force of impact and pull, wherein the set pin-pulling chain 308 provides flexible adjustment space, making it easier for the pin-pulling piece 309 to dock with the first rubber core pin 212-1, and the lateral movement component 41 can adjust the position of the gate 1-1. In conjunction with the two sets of cutting components 42, the second rubber core disassembly knife 4203 is driven to insert into both sides of the second rubber core 22-1. The second rubber core 22-1 is separated by lateral displacement. Therefore, the replacement quality of the rubber core component 2-1 on the gate 1-1 is improved, the maintenance efficiency is increased and the labor intensity is reduced.
