Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology, and in particular to a disassembly device for gas turbine equipment maintenance. Background Technology

[0002] A gas turbine is an internal combustion power machine that uses a continuously flowing gas as a working fluid to drive an impeller to rotate at high speed, converting the energy of fuel into useful work. It is a type of rotating impeller thermal engine.

[0003] Because of the hydrocyclone's unique installation location, it can only be pulled outwards, requiring considerable force to remove. In actual overhauls, maintenance personnel typically loosen the hydrocyclone by tapping its head with a hammer before removing it. This method has the following drawbacks:

[0004] 1. The disassembly of the hydrocyclone takes too long. Often, when a major overhaul reaches this stage, it will take a long time, resulting in an extension of the overall project schedule.

[0005] 2. It is difficult to accurately control the striking force during the disassembly of the hydrocyclone, which can easily damage the hydrocyclone. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a disassembly device for gas turbine equipment maintenance: the adjusting screw drives the extension rod to descend through the sliding plate and threaded block, and the pulling protrusion on the outer wall of the extension rod and the stepped groove expand the inner diameter and contact the outer wall of the part and lock it on the part, avoiding knocking to remove the part, reducing damage to the part, facilitating disassembly, and solving the problem caused by knocking to remove the part.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A disassembly device for overhauling gas turbine equipment includes a support rod. Adjustment grooves are formed at the center of the bottom of the three outer walls of the support rod, and a drive groove is formed at the top of the adjustment grooves at the top of the support rod. An adjustment screw is rotatably connected to the inner wall of one end of the adjustment groove via a bearing, and an adjustment structure is threadedly connected to the outer wall of the adjustment screw. The adjustment structure includes a threaded block threaded to the outer wall of the adjustment screw, a sliding plate welded to the outer wall of one side of the threaded block, an extension rod welded to the center of the top of the sliding plate, and a pulling protrusion welded to the outer wall of the top of the extension rod.

[0009] Preferably, the outer wall of the threaded block is slidably connected to the inner wall of the adjusting groove, and one side of the outer wall of the sliding plate is slidably connected to the outer wall of the support rod, and the welding point between the sliding plate and the extension rod is provided with reinforcing ribs;

[0010] The adjusting screw drives the extension rod to descend via the sliding plate and threaded block. As the inner diameter of the extension rod expands, the pulling protrusion and stepped groove on the outer wall of the part come into contact with and lock onto the part, preventing the part from being knocked off, reducing damage to the part, and facilitating disassembly.

[0011] Preferably, the outer wall of the support rod is provided with stabilizing grooves at both ends of the adjusting groove, and a stabilizing strip is welded to one side of the outer wall of the sliding plate at the stabilizing groove, and the outer wall of the stabilizing strip is slidably connected to the inner wall of the stabilizing groove.

[0012] Preferably, one side of the outer wall of the extension rod has an arc-shaped structure, and a stepped groove is provided on one side of the outer wall of the extension rod.

[0013] Preferably, a drive motor is installed on the inner wall of the drive groove, and a gear one is installed on the output shaft of the drive motor. A gear two is installed on the outer wall of one end of the adjusting screw of the drive groove, and the gear two meshes with the gear one.

[0014] Preferably, the outer wall of the support rod has equidistantly distributed heat dissipation holes at the drive groove, and a handle is welded to the center of the bottom outer wall of the support rod.

[0015] Preferably, the drive motor is connected to the switch via a wire, and the switch is connected to the power supply via a wire.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The adjusting screw drives the extension rod to descend through the sliding plate and threaded block. As the inner diameter of the extension rod expands, the pulling protrusion and stepped groove contact the outer wall of the part and lock onto the part, avoiding knocking to remove the part, reducing damage to the part, and facilitating disassembly.

[0018] 2. Adjusting the screw drives the extension rod to descend. As it descends, the extension rods move further apart from each other. The pulling protrusions on the outer wall of the extension rod and the stepped groove expand their internal force and contact the outer wall of the part, thus locking it onto the part. This makes it easier to fix the part, to set a force point on the part, and to pull the part out. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Reference Figure 1-4 As shown, a disassembly device for overhauling gas turbine equipment includes a support rod 1. An adjustment groove 3 is provided at the center of the bottom of the three outer walls of the support rod 1, and a drive groove 4 is provided at the top of the adjustment groove 3. An adjustment screw 5 is rotatably connected to the inner wall of one end of the adjustment groove 3 through a bearing, and an adjustment structure 6 is threadedly connected to the outer wall of the adjustment screw 5.

[0027] A drive motor 7 is installed on the inner wall of the drive groove 4, and a gear 8 is installed on the output shaft of the drive motor 7. A gear 9 is installed on the outer wall of one end of the adjusting screw 5 of the drive groove 4, and the gear 9 meshes with the gear 8. When the drive motor 7 starts, it drives the adjusting screw 5 to rotate in the adjusting groove 3 through the gear 8 and the gear 9, which facilitates driving.

[0028] The outer wall of the support rod 1 has heat dissipation holes 18 that are evenly distributed at the drive groove 4, and a handle 2 is welded to the center of the bottom outer wall of the support rod 1.

[0029] The drive motor 7 is connected to the switch via a wire, and the switch is connected to the power supply via a wire.

[0030] Example 2:

[0031] Reference Figure 1-3As shown, the adjustment structure 6 includes a threaded block 11 threaded to the outer wall of the adjustment screw 5, a sliding plate 12 welded to the outer wall of one side of the threaded block 11, an extension rod 14 welded to the top center of the sliding plate 12, and a pulling protrusion 16 welded to the outer wall of the top of the extension rod 14. As the extension rods 14 descend, they move further apart, increasing the inner diameter of the extension rods 14. The pulling protrusion 16 and the stepped groove 17 on the outer wall of the extension rod 14 contact the outer wall of the part and lock onto the part as the inner force expands. At this time, the personnel can pull the support rod 1 outward to disassemble the part, avoiding knocking to remove the part and reducing damage to the part.

[0032] The outer wall of the threaded block 11 is slidably connected to the inner wall of the adjusting groove 3, and one side of the outer wall of the sliding plate 12 is slidably connected to the outer wall of the support rod 1. The welding point of the sliding plate 12 and the extension rod 14 is provided with a reinforcing rib 15. The connection point of the extension rod 14 and the sliding plate 12 is welded with a reinforcing rib 15 to improve the strength between the extension rod 14 and the sliding plate 12 and ensure the stability of the extension rod 14.

[0033] The outer wall of the support rod 1 is provided with stabilizing grooves 10 at both ends of the adjustment groove 3, and a stabilizing strip 13 is welded to one side of the outer wall of the sliding plate 12 at the stabilizing groove 10. The outer wall of the stabilizing strip 13 is slidably connected to the inner wall of the stabilizing groove 10. During the sliding process of the sliding plate 12, its own stabilizing strip 13 is slidably connected in the stabilizing groove 10 to ensure the stability of the adjustment process.

[0034] One side of the outer wall of the extension rod 14 is an arc-shaped structure, and a stepped groove 17 is provided on one side of the outer wall of the extension rod 14. The adjusting screw 5 drives the extension rod 14 to move up and down through the threaded block 11 and the sliding plate 12 to adjust the distance between the extension rods 14, which is convenient for adjustment, easy for insertion, and easy for fixing parts.

[0035] Working principle: In use, start the drive motor 7 in the drive groove 4 inside the support rod 1. The drive motor 7 drives the adjusting screw 5 to rotate in the adjusting groove 3 through gear 8 and gear 9. After the adjusting screw 5 rotates, the threaded block 11 and the sliding plate 12 slide upward on the support rod 1. The sliding plate 12 slides upward on the support rod 1, causing multiple extension rods 14 to move upward and move closer to each other. After the extension rods 14 move closer to each other, the inner diameter of the circle formed by the extension rods 14 becomes smaller. Hold the support rod 1 and handle 2 to insert the extension rods 14 into the equipment. The drive motor 7 rotates in the opposite direction, driving the adjusting screw 5 to rotate. The adjusting screw 5 drives the extension rods 14 to descend through the sliding plate 12 and the threaded block 11. As they descend, the extension rods 14 move further apart, increasing the inner diameter of the extension rods 14. The pulling protrusion 16 and the stepped groove 17 on the outer wall of the extension rod 14 expand their inner force and contact the outer wall of the part and get stuck on the part. At this time, the person can pull the support rod 1 outward to disassemble the part, avoiding knocking to remove the part and reducing damage to the part.
