Description

Technical Field

[0001] This invention relates to an adjustable gas turbine replacement device, belonging to the field of gas turbine technology. Background Technology

[0002] A gas turbine is a device that uses natural gas, petroleum gas, or other fuels to generate electricity by producing high-temperature, high-pressure gas through combustion, which drives a turbine to rotate and in turn drives a generator. Compared with traditional thermal power generation, gas turbines have advantages such as rapid start-up, low investment cost, low vibration, and low pollution. Therefore, gas turbines have been widely used in various fields such as power, heat, refrigeration, and propulsion, including thermal power generation, aviation, shipbuilding, and industrial production.

[0003] Gas turbine conversion refers to the process of converting some existing power generation systems from using traditional fuels (such as coal and oil) to using natural gas or liquefied gas as fuel. This system conversion usually requires replacing or adjusting parts such as the combustion chamber, combustion control system, inlet and outlet pipelines and emission equipment to adapt to the new fuel and to utilize its energy more efficiently.

[0004] Chinese utility model patent CN211034102U discloses an adjustable gas turbine replacement device, which comprises a gas turbine guide rail assembly, a replacement device frame, a replacement device moving assembly, a replacement device fixing assembly, and a gas turbine guide rail assembly adjustment pad. The gas turbine guide rail assembly is bolted to the replacement device frame, and the gas turbine guide rail assembly adjustment pad is placed in the middle. The replacement device moving assembly is connected to the replacement device frame using heavy-duty studs. The replacement device fixing assembly is also connected to the replacement device frame using heavy-duty studs. The whole device is adjustable and can transport the gas turbine.

[0005] The above-mentioned example has a certain degree of adjustability and transportation function, but it still has shortcomings in actual use: 1. Insufficient support angle adjustment capability leads to insufficient transportation stability: As a high-precision and high-mass equipment, the center of gravity and stress points of the gas turbine will change dynamically under different working conditions (such as flat ground transfer, obstacle crossing, positioning and docking). The existing structure cannot be adapted to the changes, resulting in poor stability when the equipment is transported under complex road conditions or postures, which may easily cause the equipment to overturn or damage to internal components.

[0006] 2. During the replacement operation, the lack of an effective active clamping and positioning mechanism, relying solely on simple frame support, cannot effectively suppress the shaking and displacement of the gas turbine during hoisting, disassembly, or installation. This not only directly threatens the safety of on-site operators but also leads to difficulties in component docking, severely reducing the accuracy and efficiency of the replacement operation. It may even cause damage to high-value gas turbine components due to impacts.

[0007] Therefore, improvements are urgently needed. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, the present invention designs an adjustable gas turbine replacement device, which is convenient to replace and has good stability.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable gas turbine replacement device includes a movable frame, the movable frame including a movable base and a movable frame movably installed at the front end of the base and extending out of the base, a clamping frame installed at the top of the movable frame, and a hinged pushing mechanism installed between the base and the movable frame. The hinged push mechanism includes a drive device 1 hinged to the base. A reinforcing adjustment main rod is hinged to the top of the drive device 1. The bottom end of the reinforcing adjustment main rod is hinged to the movable frame. A swing frame is hinged to the top of the reinforcing adjustment main rod. The swing frame is hinged to the base and the movable frame respectively.

[0010] Furthermore, the swing frame includes an extension frame and a reinforcing changing frame. The extension frame is horizontally movably disposed within the opening of the U-shaped base. The reinforcing changing frame is vertically fixedly installed at the rear end of the extension frame, and the clamping frame is fixedly installed at the front end of the extension frame.

[0011] Furthermore, the swing frame includes a positioning bracket, a limiting pull rod, and a traction rod. Two limiting pull rods are symmetrically hinged on both sides of the positioning bracket, and the free ends of the two limiting pull rods are hinged to the reinforced replacement frame. Traction rods are integrally fixedly connected to the bottom ends of both sides of the positioning bracket, and the free ends of the two traction rods are hinged to the base. The reinforced adjustment main rod is hinged between the two traction rods.

[0012] Furthermore, a support arc bracket is fixedly installed at the top of the base, and a buffer pad is fixedly installed at the top of the support arc bracket at a position directly below the limiting pull rod.

[0013] Furthermore, the clamping frame includes a reinforcing support plate, a support frame plate is fixedly installed on one side of the top of the reinforcing support plate, and a guide frame is fixedly installed on the other side of the top of the reinforcing support plate. A clamping block one is vertically and movably inserted through the support frame plate, and a clamping block two is vertically and movably inserted through the guide frame. The clamping block one and the clamping block two are arranged opposite to each other. The clamping frame also includes a driving component for driving the clamping block one and the clamping block two to move closer to each other or further away from each other.

[0014] Furthermore, the clamping block one includes a sliding rod, with a sliding top plate and a second clamping plate fixedly connected to both ends of the sliding rod, and the second clamping plate is disposed between the support frame plate and the guide frame; the clamping block two includes a guide rod, with a first clamping plate and a connecting plate fixedly connected to both ends of the guide rod, and the first clamping plate is disposed between the support frame plate and the guide frame.

[0015] Furthermore, the driving assembly includes a second driving device for driving the sliding rod to move laterally. A first toothed rod is fixedly installed at the bottom end of the sliding plate. The first toothed rod is meshed with a gear assembly installed on the support frame plate. The gear assembly is synchronously meshed with a second toothed rod. A connecting rod is fixedly sleeved at the end of the second toothed rod. The free end of the connecting rod moves through the support frame plate and is fixedly connected to an arc connecting rod. The arc connecting rod is fixedly connected to the first clamping plate.

[0016] Furthermore, the gear assembly includes a bearing housing and a first gear and a second gear rotatably mounted on the bearing housing, wherein the first gear meshes with a first rack and the second gear meshes with a second rack.

[0017] Furthermore, a guide cylinder that is movably sleeved outside the sliding rod is fixedly connected to the support frame plate.

[0018] Furthermore, handles are fixedly connected to both sides of the positioning bracket.

[0019] Compared with the prior art, the present invention has the following features and beneficial effects: 1. When in use, the present invention can be driven by the drive device to rotate or reset the main adjustment rod according to the needs, thereby driving the traction rod to rotate and fold the drive limit pull rod and the displacement of the reinforcing replacement frame, so as to realize the diversity of steam turbine items replacement and realize different replacement modes according to different needs.

[0020] 2. In this invention, when the main adjustment rod is rotated for adjustment, the limiting pull rod limits the position of the reinforcing replacement frame after adjustment and the angle of the traction rod after adjustment, so as to prevent the reinforcing replacement frame from shifting when subjected to subsequent forces after adjustment, and ensure the stability of the device during replacement.

[0021] 3. When the output end of the drive device of the present invention retracts and drives the reinforcing adjustment main rod to reset, the bottom of the reinforcing adjustment main rod will contact the support arc bracket and the buffer pad, and be supported by the support arc bracket and the buffer pad, so as to prevent the reinforcing adjustment main rod from losing the traction force of the first hydraulic rod and losing its limit, making the reinforcing changing frame more stable when supporting the items in the base.

[0022] 4. In this invention, the sliding top plate is displaced by the second driving device, which causes the second gear and the first gear to rotate and drive the displacement of various structures on the second rack and crossbar, thereby causing the first clamping plate to move closer to the second clamping plate and clamp the item in the first and second clamping plates. At the same time, by extending and retracting the output end of the second hydraulic rod, the second clamping plate is driven to move closer to the first clamping plate or the first clamping plate moves closer to the second clamping plate, so as to achieve versatility and stability in clamping the item during changing clothes.

[0023] 5. Through the corresponding cooperation of various structures, the device can realize different replacement modes according to different needs during use, achieving diversity in the replacement of steam turbine items. It avoids the displacement phenomenon of the reinforcing replacement frame supporting the steam turbine items after adjustment, ensuring the stability of the device during replacement. By extending and retracting the output end of the second hydraulic rod, the second clamping plate is driven to move closer to the first clamping plate or the first clamping plate moves closer to the second clamping plate, realizing the diversity and stability of clamping items during replacement. It is convenient to use and has good practicality. Attached Figure Description

[0026] The present invention will now be described in more detail with reference to the embodiments.

[0027] Example 1 Please see Figures 1 to 4 The adjustable gas turbine replacement equipment in this embodiment includes a movable frame.

[0028] Specifically, the mobile frame includes a movable base 1 and a movable frame 5 that is movably mounted on the front end of the base 1 and can extend out of the base 1. The movable frame 5 is a vertically arranged rectangular frame.

[0029] In this embodiment, the base 1 has a U-shaped structure, and a support pulley 207 is installed at the front end of the base 1. An L-shaped frame is fixedly installed at the rear end of the base 1. A caster wheel 106 is installed at the free end of the L-shaped frame. There are two support pulleys 207, which are respectively set on both sides of the movable frame 5. There are also two caster wheels 106, which are set one-to-one with the support pulleys 207.

[0030] The installation of casters 106 and support casters 207 facilitates the movement of the mobile frame.

[0031] The movable frame 5 is equipped with a clamping frame at its top, and a hinged pushing mechanism is also installed between the base 1 and the movable frame 5. The hinged pushing mechanism is used to lift the movable frame 5 away from the base 1, thereby changing the position of the clamping frame.

[0032] Specifically, the articulated push mechanism includes a drive device 201 articulated on the base 1. In this embodiment, the drive device 201 is a hydraulic drive rod.

[0033] Please see Figure 2 The base 1 has a support shaft pin seat 2 installed at the top, and the bottom end of the drive device 201 is hinged to the support shaft pin seat 2.

[0034] The top of the drive device 201 is hinged to a reinforcing adjustment main rod 103. Specifically, a shaft pin top seat 202 is fixedly installed at the bottom of the reinforcing adjustment main rod 103, and the top of the drive device 201 is hinged to the shaft pin top seat 202.

[0035] Meanwhile, the bottom end of the reinforcing adjustment main rod 103 is set inside the movable frame 5 and is hinged to the movable frame 5. The top end of the reinforcing adjustment main rod 103 is hinged to a swing frame, and the swing frame is hinged to the base 1 and the movable frame 5 respectively.

[0036] Specifically, the swing frame includes an extension frame 206 and a reinforced changing frame 104. The extension frame 206 is horizontally movably disposed within the opening of the U-shaped base 1.

[0037] The reinforcing changing frame 104 is vertically fixedly installed at the rear end of the extension frame 206, and the clamping frame is fixedly installed at the front end of the extension frame 206.

[0038] Please see Figure 1 and Figure 2 The swing frame includes a positioning bracket 102, a limiting pull rod 203, and a traction rod 101.

[0039] The positioning bracket 102 has two symmetrically hinged limit pull rods 203 on both sides, and the free ends of the two limit pull rods 203 are hinged to the reinforced replacement frame 104.

[0040] Both sides of the positioning bracket 102 are integrally fixedly connected with traction rods 101, and the free ends of the two traction rods 101 are hinged to the base 1.

[0041] Meanwhile, the main adjustment rod 103 is hinged and installed between the two traction rods 101.

[0042] Furthermore, a support arc bracket 204 is fixedly installed at the top of the base 1. A buffer pad 205 is fixedly installed at the top of the support arc bracket 204 directly below the limiting pull rod 203. The buffer pad 205 can be used to support the downward swinging reinforcing adjustment rod 103 and improve the stability of the device.

[0043] Furthermore, handles 105 are fixedly connected to both sides of the positioning bracket 102 to facilitate movement by staff.

[0044] Example 2 Please see Figure 1 , Figure 5 and Figure 6 The adjustable gas turbine replacement equipment of this embodiment, based on the above embodiment one, includes a clamping frame including a reinforcing support plate 3, a support frame plate 305 fixedly installed on one side of the top of the reinforcing support plate 3, and a guide frame 301 fixedly installed on the other side of the top of the reinforcing support plate 3. A clamping block one is vertically and movably inserted into the support frame plate 305, and a clamping block two is vertically and movably inserted into the guide frame 301. The clamping block one and the clamping block two are arranged opposite to each other. The clamping frame also includes a driving component for driving the clamping block one and the clamping block two to move closer to each other or further away from each other. Clamping is achieved by the clamping block one and the clamping block two moving closer to each other.

[0045] Specifically, the clamping block includes a sliding rod 3061, with a sliding top plate 309 and a second clamping plate 307 fixedly connected to both ends of the sliding rod 3061. Both the sliding top plate 309 and the second clamping plate 307 serve to prevent the sliding rod 3061 from slipping off.

[0046] The second clamping plate 307 is disposed between the support frame plate 305 and the guide frame 301.

[0047] The clamping block 2 includes a guide rod 302, with a first clamping plate 304 and a connecting plate 303 fixedly connected to both ends of the guide rod 302. Both the first clamping plate 304 and the connecting plate 303 serve to prevent the guide rod 302 from slipping.

[0048] The first clamping plate 304 is disposed between the support frame plate 305 and the guide frame 301.

[0049] The drive assembly includes a second drive device 306 for driving the sliding rod 3061 to move laterally, and the second drive device 306 is also a hydraulic drive rod.

[0050] When the sliding rod 3061 moves laterally, the sliding top plate 309 fixed at the end of the sliding rod 3061 will also move synchronously.

[0051] Therefore, a first toothed rod 4 is fixedly installed at the bottom of the sliding plate 309. The first toothed rod 4 is meshed with a gear assembly installed on the support frame plate 305. The gear assembly is synchronously meshed with a second toothed rod 404. A connecting rod is fixedly sleeved at the end of the second toothed rod 404. The free end of the connecting rod moves through the support frame plate 305 and is fixedly connected to an arc connecting rod 407. The arc connecting rod 407 is fixedly connected to the first clamping plate 304.

[0052] In this embodiment, the linkage includes a misaligned ball joint rod 406 and crossbars 405 fixedly installed at both ends of the misaligned ball joint rod 406. One crossbar 405 is fixedly installed through the arc connecting rod 407, and the other crossbar 405 is movably installed through the support frame plate 305 and then fixedly sleeved with the second toothed rod 404.

[0053] The misaligned ball joint rod 406 ensures that the power transmission of the drive device 306 can drive the entire system smoothly and without obstruction, allowing the two clamping plates to smoothly complete the clamping and releasing actions.

[0054] The gear assembly includes a bearing housing 401 and a first gear 402 and a second gear 403 rotatably mounted on the bearing housing 401. The first gear 402 is meshed with a first rack 4, and the second gear 403 is meshed with a second rack 404.

[0055] Furthermore, a guide cylinder 308 is fixedly connected to the support frame plate 305 and movably sleeved outside the sliding rod 3061 to improve the stability of the movement.

[0056] The working principle of this invention is as follows: When in use, the operator holds the handle 105, and the device is moved by the universal wheel 106 and the support pulley 207.

[0057] During the replacement process, the drive unit 201 is activated, which drives the shaft pin top seat 202 to move. The extension of the shaft pin top seat 202 will drive the reinforcing adjustment main rod 103 to rotate first along the axis point where the reinforcing adjustment main rod 103 is connected to the positioning bracket 102.

[0058] By increasing the traction force when the main rod 103 rotates, the reinforced changing frame 104 can extend out from the base 1, thereby achieving angle and position adjustment.

[0059] The limiting pull rod 203 can limit the position of the reinforcing changing frame 104 after adjustment and the angle of the traction rod 101 after adjustment, so as to prevent the reinforcing changing frame 104 from shifting when subjected to subsequent force after adjustment.

[0060] When the output end of the drive device 201 is retracted, it can drive the reinforcing adjustment main rod 103 to reset. The reinforcing changing frame 104 is stored in the base 1 due to the traction force when the reinforcing adjustment main rod 103 rotates, realizing the versatility of the device when changing clothes.

[0061] At the same time, when the output end of the drive device 201 retracts and drives the reinforcing adjustment main rod 103 to reset, the bottom of the reinforcing adjustment main rod 103 will contact the support arc bracket 204 and the buffer pad 205, and be supported by the support arc bracket 204 and the buffer pad 205, so as to prevent the reinforcing adjustment main rod 103 from losing the traction force of the drive device 201 and losing its limit, making the reinforcing changing rack 104 more stable when supporting items in the base 1.

[0062] During the replacement process, the drive device 306 is activated, which drives the second clamping plate 307 to move. When the second clamping plate 307 moves, it causes the sliding top plate 309 to move. When the sliding top plate 309 moves, it causes the first rack 4 to move. The first rack 4 meshes with the first gear 402, causing the first gear 402 to rotate due to the traction force when the first rack 4 moves. This causes the second gear 403 to rotate. The second gear 403 meshes with the second rack 404, causing the second rack 404 to move when the second gear 403 rotates. This causes the crossbar 405 to move.

[0063] When the crossbar 405 moves, it causes the arc connecting rod 407 to move, so that the first clamping plate 304 can slide on the guide frame 301 through the guide rod 302, so that the first clamping plate 304 moves closer to the second clamping plate 307, and clamps the item in the first clamping plate 304 and the second clamping plate 307.

[0064] By extending and retracting the output end of the second drive device 306, the second clamping plate 307 is driven to move closer to the first clamping plate 304 or the first clamping plate 304 moves closer to the second clamping plate 307, thereby achieving versatility and stability in clamping items during clothing changes.
