Description

Technical Field

[0001] The utility model relates to the technical field of disassembly of the telescopic cylinder of an impeller lock, and particularly relates to a safety disassembly device for the telescopic cylinder of an impeller lock. Background Technique

[0002] In the field of wind power generation, with the continuous increase in the operating years of wind turbines, the importance of wind turbine maintenance and safety operations has become increasingly prominent. The telescopic cylinder of the impeller lock is a key component to ensure the safety of the wind turbine during shutdown maintenance. The telescopic cylinder of the impeller lock is a part of a hydraulic cylinder or a mechanical transmission device, and through its adjustable length, the control of the impeller lock is realized.

[0003] In practical applications, the problem that the telescopic cylinder of the impeller lock cannot be smoothly pulled out often occurs, which seriously affects the normal operation of the wind turbine and the rapid maintenance response. The gearbox adjacent to the front of the impeller lock, due to its complex geometric shape and the design feature of no reliable hanging point, brings great challenges to the pulling-out operation of the telescopic cylinder of the impeller lock. The traditional direct pulling-out method is not only difficult to implement in the absence of an effective support point, but also has great safety risks. Blindly increasing the pulling force not only cannot solve the problem, but may also cause the hanging point to fail, resulting in the rapid unloading and bursting of the zipper. In the lightest case, it may cause damage to the wind turbine equipment, and in the most serious case, it may cause serious personal injury accidents. Content of the Utility Model

[0004] In order to facilitate the disassembly of the telescopic cylinder of the impeller lock and improve the safety of disassembling the telescopic cylinder of the impeller lock, the present application provides a safety disassembly device for the telescopic cylinder of the impeller lock.

[0005] The present application provides a safety disassembly device for the telescopic cylinder of the impeller lock, including a connection tooling and a pulling member for pulling the connection tooling to move. The connection tooling is fixedly connected to the telescopic cylinder of the impeller lock, and the pulling member is connected to the connection tooling.

[0006] The beneficial effect of the utility model is that when it is necessary to disassemble the telescopic cylinder of the impeller lock, the pulling member is started, and the pulling member drives the telescopic cylinder of the impeller lock to move outwards through the connection tooling, thereby completing the disassembly of the telescopic cylinder of the impeller lock. The operation is simple, the convenience of disassembling the telescopic cylinder of the impeller lock is improved, and the safety of disassembling the telescopic cylinder of the impeller lock is improved.

[0007] Further, the telescopic cylinder of the impeller lock is installed in the main shaft bracket, and the pulling direction of the pulling member relative to the connection tooling is the same as the direction in which the telescopic cylinder of the impeller lock is removed from the main shaft bracket.

[0008] The beneficial effect of adopting the above further scheme is that it can effectively eliminate the risks during the process of obliquely pulling and forcibly dragging during the disassembly of the telescopic cylinder of the impeller lock, and effectively avoid equipment damage and personal injury.

[0009] Further, the pulling member is a hollow jack, and the telescopic direction of the hollow jack is the same as the removal direction of the telescopic cylinder of the impeller lock.

[0010] The beneficial effects of adopting the above further scheme are as follows: The hollow jack can provide stable and controllable thrust or pulling force. When disassembling the telescopic cylinder of the impeller lock, by precisely controlling the telescoping of the hollow jack, it can ensure the smooth progress of the disassembly process of the telescopic cylinder of the impeller lock, reduce the impact and vibration caused by improper operation, thereby protecting the equipment and related components from damage. At the same time, it can effectively eliminate the risk during the process of oblique pulling and hard dragging during the disassembly of the telescopic cylinder of the impeller lock, and effectively avoid equipment damage and personal injury.

[0011] Further, the connecting tooling includes a first sleeve, a second sleeve, and a connecting rod. One end face on one side of the first sleeve is provided with an opening, and the other end face on the other side of the first sleeve is fixedly connected to the connecting rod. The first sleeve is sleeved outside the telescopic cylinder of the impeller lock, and the bottom of the first sleeve with the opening is fixedly connected to the telescopic cylinder of the impeller lock;

[0012] The second sleeve is sleeved outside the first sleeve. One end face on one side of the second sleeve is provided with an opening, and the other end face on the other side of the second sleeve is inserted into the connecting rod. The bottom of the second sleeve with the opening abuts against the side wall of the main shaft bracket corresponding to the telescopic cylinder of the impeller lock;

[0013] The telescopic end of the hollow jack is fixedly connected to the connecting rod, and the bottom surface of the hollow jack abuts against the end face of the second sleeve away from the main shaft bracket.

[0014] The beneficial effects of adopting the above further scheme are as follows: The second sleeve supports the hollow jack. When the hollow jack extends, it drives the connecting rod to move away from the main shaft bracket. The connecting rod drives the telescopic cylinder of the impeller lock to move away from the main shaft bracket through the first sleeve, thereby completing the disassembly of the telescopic cylinder of the impeller lock.

[0015] Further, the length of the second sleeve is greater than the length of the first sleeve.

[0016] The beneficial effects of adopting the above further scheme are as follows: When the hollow jack extends, it is convenient for the first sleeve to move within the second sleeve.

[0017] Further, a plurality of reinforcing ribs are connected between the connecting rod and the first sleeve.

[0018] The beneficial effects of adopting the above further scheme are as follows: The arrangement of a plurality of reinforcing ribs can make the load distribution between the connecting rod and the first sleeve more uniform, avoid local stress concentration, and reduce the risk of damage caused by stress concentration.

[0019] Further, there are multiple first bolt holes corresponding to the impeller lock telescopic cylinder. The bottom of the first sleeve with an opening is fixedly connected to a connecting plate, and multiple second bolt holes corresponding to the first bolt holes are formed in the connecting plate. Bolts are respectively arranged between each of the first bolt holes and the corresponding second bolt hole.

[0020] The beneficial effect of adopting the above further scheme is that the fixed connection between the connecting plate and the impeller lock telescopic cylinder can be realized through bolts, thereby improving the convenience of fixing the first sleeve to the impeller lock telescopic cylinder.

[0021] Further, the device further includes a hydraulic monitoring device corresponding to the hollow jack for real-time monitoring of the hydraulic value of the hollow jack.

[0022] The beneficial effect of adopting the above further scheme is that when pressurizing the hollow jack, the change in the hydraulic value monitored by the hydraulic monitoring device can reflect the pulling-out state of the impeller lock telescopic cylinder.

[0023] Further, the hollow jack is inserted into the connecting rod, and a fixing nut is threadedly connected to the end of the connecting rod away from the first sleeve.

[0024] The beneficial effect of adopting the above further scheme is that by rotating the fixing nut, the hollow jack can be fixed to the connecting rod, thereby improving the convenience of fixing the hollow jack. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application will be further described in detail below with reference to the drawings.

[0032] The embodiment of the present application discloses a safety disassembly device for an impeller lock telescopic cylinder. As Figures 1 - 3 shown, it includes a connecting tooling and a pulling member. The connecting tooling is fixedly connected to the impeller lock telescopic cylinder, and the pulling member is connected to the connecting tooling. When it is necessary to disassemble the impeller lock telescopic cylinder, the pulling member is started, and the pulling member drives the impeller lock telescopic cylinder to move outwards through the connecting tooling, thereby completing the disassembly of the impeller lock telescopic cylinder. The operation is simple, which improves the convenience of disassembling the impeller lock telescopic cylinder and enhances the safety of disassembling the impeller lock telescopic cylinder.

[0033] The impeller lock telescopic cylinder is installed in the main shaft bracket. Since the gearbox is directly in front of the impeller lock, the shapes of the gearbox and the impeller lock are irregular and there are no reliable hanging points. If tools such as a chain block are used to disassemble the telescopic cylinder, it is impossible to ensure that the force application point and the force receiving point are on the same center, resulting in the inability to pull out the impeller lock telescopic cylinder. Blindly increasing the pulling force will cause the hanging point to be unable to bear the pulling force and fall off, leading to the rapid unloading and bursting of the zipper. In the light case, it will damage the fan equipment, and in the severe case, it will cause personal injury. In this embodiment, the pulling direction of the pulling member relative to the connecting tooling is the same as the direction in which the impeller lock telescopic cylinder is removed from the main shaft bracket, thereby effectively eliminating the risk during the process of obliquely pulling and forcibly dragging during the disassembly of the impeller lock telescopic cylinder, and effectively avoiding equipment damage and personal injury.

[0034] In this embodiment, the pulling member can be a hollow jack 2, and the telescopic direction of the hollow jack 2 is the same as the direction in which the impeller lock telescopic cylinder is removed from the main shaft bracket.

[0035] It is easy to understand that the impeller lock telescopic cylinder is used to drive the impeller lock to move, so that the impeller lock extends or enters the main shaft bracket. As Figures 1 - 3 shown, in this embodiment, the connecting tooling includes a first sleeve 1, a second sleeve 3 and a connecting rod 4. One end face on one side in the first sleeve 1 is provided with an opening, and the other end face in the first sleeve 1 is fixedly connected to the connecting rod 4. The first sleeve 1 is sleeved outside the impeller lock telescopic cylinder, and the bottom of the first sleeve 1 with the opening is fixedly connected to the impeller lock telescopic cylinder. The second sleeve 3 is sleeved outside the first sleeve 1. One end face on one side in the second sleeve 3 is provided with an opening, and the other end face in the second sleeve 3 is inserted into the connecting rod 4. The bottom of the second sleeve 3 with the opening abuts against the side wall of the main shaft bracket.

[0036] As Figure 1 and Figure 2 shown, the hollow jack 2 can be installed on the connecting rod 4. The telescopic end of the hollow jack 2 is fixedly connected to the connecting rod 4, and the bottom surface of the hollow jack 2 abuts against the end face of the second sleeve 3 away from the main shaft bracket. The second sleeve 3 supports the hollow jack 2. When the hollow jack 2 extends, it drives the connecting rod 4 to move away from the main shaft bracket. The connecting rod 4 drives the impeller lock telescopic cylinder to move away from the main shaft bracket through the first sleeve 1, thereby completing the disassembly of the impeller lock telescopic cylinder.

[0037] In this embodiment, the length of the second sleeve 3 is greater than that of the first sleeve 1, so that when the hollow jack 2 extends, the first sleeve 1 can move within the second sleeve 3. The first sleeve 1 can be a cylindrical tooling with a length of 210 mm, and the second sleeve 3 can be a rectangular tooling with a width of 195 mm and a length of 390 mm.

[0038] As Figure 2 shown, a plurality of reinforcing ribs 41 are connected between the connecting rod 4 and the first sleeve 1. The arrangement of the plurality of reinforcing ribs 41 can make the load distribution between the connecting rod 4 and the first sleeve 1 more uniform, avoid local stress concentration, and reduce the risk of damage caused by stress concentration.

[0039] It is easy to understand that, as Figure 1 and Figure 2 shown, the impeller lock telescopic cylinder corresponds to a plurality of first bolt holes 6. In this embodiment, the bottom of the first sleeve 1 with an opening is fixedly connected with a connecting plate 11, and a plurality of second bolt holes 12 corresponding to the first bolt holes 6 are opened on the connecting plate 11. Bolts are respectively arranged between each first bolt hole 6 and the corresponding second bolt hole 12. Through the bolts, the fixed connection between the connecting plate 11 and the impeller lock telescopic cylinder can be realized, thereby improving the convenience of fixing the first sleeve 1 and the impeller lock telescopic cylinder.

[0040] As Figure 1 and Figure 3 shown, in this embodiment, the hollow jack 2 is inserted into the connecting rod 4, and a fixing nut 42 is threadedly connected to the end of the connecting rod 4 away from the first sleeve 1. By rotating the fixing nut 42, the hollow jack 2 can be fixed to the connecting rod 4, thereby improving the convenience of fixing the hollow jack 2. The connecting rod 4 can be threaded at the end away from the first sleeve 1 or can be threaded as a whole.

[0041] As Figure 4 shown, the hollow jack 2 corresponds to a hydraulic monitoring device 5. The hydraulic monitoring device 5 is used to monitor the hydraulic value of the hollow jack 2 in real time. When the hollow jack 2 is pressurized, the change of the hydraulic value monitored by the hydraulic monitoring device 5 can reflect the pulling-out state of the impeller lock telescopic cylinder. The hydraulic monitoring device 5 can be a pressure gauge or a combination of a pressure sensor and a display screen.

[0042] When pressurizing the hollow jack 2, if the hydraulic value monitored by the hydraulic monitoring device 5 no longer changes, it indicates that the impeller lock telescopic cylinder has been fully extended at this time, and the hollow jack 2 can be depressurized. When pressurizing the hollow jack 2, if the hydraulic value monitored by the hydraulic monitoring device 5 continues to increase, it indicates that the impeller lock telescopic cylinder has not been fully extended at this time. If depressurization is performed in this state, it may cause the sudden release of the internal pressure of the system, triggering unnecessary mechanical shocks or damages, and even potentially affecting the stability and safety of the entire hydraulic system.

Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features.
