Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping equipment, and in particular to a positioning and clamping device for a blowout preventer gate. Background Technology
[0002] In industrial sectors such as oil and gas exploration and extraction, blowout preventers are key equipment for ensuring drilling safety. As a crucial sealing component of the blowout preventer (BOP), the sealing core of the gate valve is subject to aging and damage under harsh conditions such as high pressure, wear, and corrosion during long-term use. It requires replacement approximately every six months to ensure the overall sealing performance of the BOP. However, due to its long-term exposure to high pressure and corrosive environments, the sealing core is prone to rust and adhesion to surrounding components, making it difficult to remove. Traditional disassembly methods often rely on workers using pipe wrenches, spanners, and pry bars, which can easily lead to tool slippage or tools flying off due to mismatch between the tools and the core's disassembly surface, making disassembly difficult and potentially causing injury. Furthermore, manual operation cannot accurately position the gate valve, and the lack of an effective clamping device causes the gate valve to wobble during disassembly, affecting overall disassembly efficiency. Additionally, the difficulty in precisely controlling the disassembly force and direction during manual operation can lead to stress concentration, causing localized tearing of the sealing core and mechanical damage to the gate valve, impacting the equipment's lifespan and overall sealing performance. Therefore, it is necessary to provide a BOP gate valve positioning and clamping device to solve the above technical problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see the appendix Figure 1 To be continued Figure 7 This utility model provides a blowout preventer gate positioning and clamping device, including an operating table 1. A left displacement mechanism 5 is provided on the left side of the operating table 1, and a right displacement mechanism 3 with the same structure as the left displacement mechanism 5 is symmetrically provided on the right side of the operating table 1. A moving groove is provided in the middle of the operating table 1, and a front-to-back displacement mechanism 2 is provided in the moving groove. A T-shaped block 206 that can engage the blowout preventer gate 4 is provided on the top of the front-to-back displacement mechanism 2.
[0026] The right displacement mechanism 3 includes a second mounting base 302, which is fixedly connected to the operating table 1. A first power unit 301 is fixedly mounted on the second mounting base 302. A tool holder 304 is fixedly mounted on the power extension end of the first power unit 301. A disassembly knife 305 is detachably connected to the front end of the tool holder 304. A disassembly slope is provided at the front end of the disassembly knife 305, and an arc-shaped opening 3051 is provided on the disassembly slope.
[0027] When it is necessary to disassemble the arc-shaped rubber core of the blowout preventer gate 4, the blowout preventer gate 4 is positioned on the operating table 1 by the front and rear displacement mechanism 2. The front and rear displacement mechanism 2 is used to move the blowout preventer gate 4 back and forth on the operating table 1 to ensure that the disassembly surface of the arc-shaped rubber core of the blowout preventer gate 4 is aligned with the disassembly knife 305 on the right displacement mechanism 3 and the left displacement mechanism 5. The disassembly slope set at the front end of the disassembly knife 305 can be quickly inserted into the disassembly surface of the arc-shaped rubber core. The positioning pin on the disassembly surface of the arc-shaped rubber core is engaged in the arc-shaped opening 3051. By moving the front and rear displacement mechanism 2 backward, the arc-shaped rubber core can be removed from the blowout preventer gate 4.
[0028] This device utilizes a right displacement mechanism 3, a left displacement mechanism 5, and a front-to-back displacement mechanism 2 to accurately position and clamp the blowout preventer gate 4 in both horizontal and vertical directions, locking the blowout preventer gate 4 in multiple dimensions at once. This prevents the blowout preventer gate 4 from shaking during disassembly, thus enabling precise control of the disassembly force and direction. The right displacement mechanism 3 and the left displacement mechanism 5 simultaneously clamp and fix both ends of the arc-shaped rubber core, ensuring uniform force distribution during disassembly. The disassembly bevel of the disassembly knife 305 can not only quickly insert into the disassembly surface of the arc-shaped rubber core, but also decompose the horizontal force into the vertical direction, making it easier for the arc-shaped rubber core to disengage from the slot. This allows the arc-shaped rubber core to be smoothly and completely removed from the blowout preventer gate 4, resulting in higher overall safety and efficiency in the disassembly process.
[0029] See appendix Figure 2 To be continued Figure 4 As shown, the right displacement mechanism 3 also includes a tool holder 303; the tool holder 303 is located on the right side of the mounting base 302; the tool holder 303 is provided with a through slot in the left and right directions, and the tool post 304 slides through the slot in the tool holder 303.
[0030] In use, the power units 301 of the right displacement mechanism 3 and the left displacement mechanism 5 simultaneously control the tool holder 304 to move towards each other in the tool holder 303 from both left and right directions, so that the disassembly slope of the disassembly knife 305 can be quickly inserted into the disassembly surface of the arc-shaped rubber core. The disassembly knives 305 on both sides lock and fix the two ends of the arc-shaped rubber core. The tool holder 303 plays a positioning and guiding role for the movement of the tool holder 304, and also has a certain supporting role.
[0031] It should be noted that the detachable connection of the disassembly knife 305 makes it easy to replace the disassembly knife 305 with a matching one for different models of gates.
[0032] Among them, the bottom left and right sides of the operating table 1 are fixedly connected to the lead screw support 309, and the lead screw 308 is rotatably arranged between the lead screw support 309. The lead screw 308 is threadedly connected to the connecting seat 306 which is connected to the bottom of the tool holder 303. A handwheel 307 is fixedly connected to one end of the lead screw 308. The bottom of the operating table 1 on both the front and rear sides of the connecting seat 306 is fixedly connected to the fixing seat 310. At least two connecting holes I are opened horizontally at intervals on the fixing seat 310. The connecting seat 306 is opened to the connecting hole II corresponding to the connecting hole I. The fixing seat 310 and the connecting seat 306 are fixedly connected by screws.
[0033] When in use, if it is necessary to adjust the position of the tool holder 303 on the operating table 1, turn the handwheel 307 to drive the lead screw 308 to rotate, thereby causing the connecting block 306 to move on the lead screw 308, which in turn drives the tool holder 303 to move in the horizontal direction. After the position is determined, use bolts to fix the connecting seat 306 on the fixed seat 310.
[0034] See appendix Figure 5 To be continued Figure 7 As shown, the front-to-back displacement mechanism 2 includes a base plate 208; side plates 201 are fixedly connected to both sides of the base plate 208, and the front ends of the two side plates 201 are fixedly installed to the mounting base 202. A power device 207 is fixedly installed on the mounting base 202, and a track slider 205 is detachably connected to the power telescopic end of the power device 207; a slide plate 210 is fixed to the top of the track slider 205, and the slide plate 210 is slidably connected to the top of the side plate 201; a connection hole 3 is opened on the slide plate 210, and a connection hole 4 corresponding to the connection hole 3 is opened on the T-block 206. The slide plate 210 and the T-block 206 are fixedly connected by screws.
[0035] The side plate 201 has a top groove 201a at the top, and the slide plate 210 slides in the top groove 201a. The side plate 201 has a bottom groove 201c at the bottom, and guide plates are provided on both sides of the bottom of the track slider 205. The guide plates slide in the bottom groove 201c. Each of the two side plates 201 has a slot 201b at one end that corresponds to the mounting base 202. The side plate 201 is fixed in the slot 201b by screws.
[0036] In use, align and insert the T-slot and T-block 206 on the top of the blowout preventer gate 4, placing the blowout preventer gate 4 on the side plate 201. Activate the second power unit 207. The second power unit 207 extends and retracts, causing the track slider 205 to slide within the bottom groove 201c of the side plate 201, simultaneously causing the slide plate 210 to slide within the top groove 201a of the side plate 201. At this time, rotate the threaded rod 211 to make the front limit plate 203 press against the blowout preventer gate 4. The front-to-back position of the blowout preventer gate 4 is now adjusted. Operate the second power unit 207 to move the blowout preventer gate 4 backward, while the disassembly blades 305 of the left displacement mechanism 5 and the right displacement mechanism 3 restrict the backward movement of the arc-shaped rubber core. The disassembly of the arc-shaped rubber core is completed through the simultaneous cooperation of the front-to-back displacement mechanism 2, the left displacement mechanism 5, and the right displacement mechanism 3.
[0037] It should be noted that an operating port is provided on the base plate 208, which corresponds to the position of the track slider 205. The operation port facilitates the back-and-forth movement of the track slider 205 on the base plate 208. The bottom groove 201c of the side plate 201 provides a running track for the power unit 207 to push the track slider 205. Rotating the threaded rod 209 further limits the front limit plate 203 blowout preventer gate 4. The slide plate 210 is slidably connected to the top groove 201a of the side plate 201, so that the slide plate 210 has a fixed movement trajectory, thereby making the movement of the T-block 206 and the slide plate 210 more stable. It should be noted that the T-block 206 and the slide plate 210 are bolted together for easy replacement. For blowout preventer gates 4 of different sizes, simply replace the T-block 206 with one of different sizes.
[0038] Among them, each of the two side plates 201 is provided with a second slot 201d at the end away from the first slot 201b. A rear limiting plate 204 is fixed in the second slot 201d by screws. The two ends of the second slot 201d are respectively connected to the top slide groove 201a and the bottom slide groove 201c. A threaded rod 209 is rotatably provided on the top of the mounting base 202. A front limiting plate 203 is fixedly connected to one end of the threaded rod 209 near the T-block 206. A handle is provided at the other end of the threaded rod 209.
[0039] The front limit plate 203 limits the forward movement of the gate, and the rear limit plate 204 limits the backward movement of the gate.
[0040] Among them, power unit 1 301 and power unit 2 207 are both hydraulic cylinders.
[0041] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The implementation principle of this utility model is described as follows:
[0042] When it is necessary to remove the arc-shaped rubber core on the blowout preventer gate 4, align and insert the T-slot and T-block 206 on the top of the blowout preventer gate 4 so that the blowout preventer gate 4 is placed on the side plate 201. The power extension end of the hydraulic cylinder drives the track slider 205 to slide in the bottom slide groove 201c at the bottom of the side plate 201, and at the same time drives the slide plate 210 to slide in the top slide groove 201a on the top of the side plate 201. At this time, rotate the threaded rod 209 to make the front limit plate 203 fit tightly against the blowout preventer gate 4. The front and rear positions of the blowout preventer gate 4 are adjusted. The hydraulic cylinders of the left displacement mechanism 5 and the right displacement mechanism 3 control the tool holder 304 to move towards each other in the tool holder 303 from the left and right directions, so that the disassembly slope of the disassembly tool 305 can be quickly inserted into the arc-shaped rubber core disassembly surface. The tool holder 303 plays a positioning and guiding role for the movement of the tool holder 304, and also has a certain supporting role. When it is necessary to adjust the position of the tool holder 303 on the operating table 1, turn the handwheel 307 to drive the lead screw 308 to rotate, and the connecting seat 306 drives the tool holder 303 to move horizontally on the lead screw 308. After the position is determined, the bolt is inserted into the threaded holes opened on the connecting seat 306 and the fixed seat 310 to fix the tool holder 303. The hydraulic cylinder drives the blowout preventer gate 4 to move backward, while the disassembly blades 305 of the left displacement mechanism 5 and the right displacement mechanism 3 restrict the backward movement of the arc-shaped rubber core. The disassembly of the arc-shaped rubber core is completed through the combined action of the front and rear displacement mechanisms 2 and the left and right displacement mechanisms 5 and 3. The blowout preventer gate 4 is engaged with the T-block 206, and the bottom groove 201c of the side plate 201 provides a running track for the hydraulic cylinder to push the track slider 205. Rotating the threaded rod 209 further limits the movement of the blowout preventer gate 4 using the front limit plate 203. The sliding plate 2... The sliding engagement of the top groove 201a of the side plate 201 with the T-block 206 and the slide plate 201 allows the slide plate 210 to have a fixed movement trajectory, thus making the movement of the T-block 206 and the slide plate 210 more stable; avoiding the blowout preventer gate 4 from shaking during disassembly, thus enabling precise control of disassembly force and direction. The left displacement mechanism 5 and the right displacement mechanism 3 are used to lock and fix the two ends of the arc-shaped rubber core, ensuring uniform force during disassembly, so that the arc-shaped rubber core can be smoothly and completely removed from the blowout preventer gate 4, and the overall safety and efficiency of the disassembly work are higher.
