Description

Technical Field

[0001] This utility model relates to the field of gas turbine component testing technology, and in particular to a test installation device and test platform for gas turbine test pieces. Background Technology

[0002] Test benches for gas turbine components often adopt a layered construction layout. In this layout, the center elevation of the test piece is more than 1.5 meters above the ground. The diameter of the test piece for high-power heavy-duty gas turbine components is even close to 3 meters. The large diameter and high center elevation bring inconvenience to the test preparation operations such as the introduction of test points and the installation of test interfaces.

[0003] Therefore, related technologies solve the interface installation problem by building a fixed test platform or using a ladder for elevated work. However, the space near the test piece on the gas turbine component test bench is limited. The elevated work platform can only provide installation and operation space and cannot meet the requirements for test point transfer. On the other hand, the use of a movable transfer box cannot meet the transfer and installation requirements of large capacity and multiple types of test points, and maintenance and adjustment are inconvenient.

[0040] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 3 As shown, a test installation device 100 for a gas turbine test piece according to an embodiment of the present invention includes an installation platform 1, a test adapter box 2, and a lifting assembly 3. The installation platform 1 has a receiving cavity 11 with a top opening. The test adapter box 2 has a first position and a second position. The test adapter box 2 is located in the receiving cavity 11 in the first position and outside the installation platform 1 in the second position. The test adapter box 2 is slidably connected to the top opening of the receiving cavity 11. The lifting assembly 3 is connected to the receiving cavity 11 and is drively connected to the test adapter box 2 so that the lifting assembly 3 can drive the test adapter box 2 to switch between the first position and the second position.

[0042] According to the embodiment of this utility model, the test installation device 100 for gas turbine test specimens provides operating space for high-altitude installation of the test interface by the installation platform 1. The test adapter box 2 is integrated on the installation platform 1, and the test adapter box 2 is switched between a first position and a second position by the lifting component 3, which means that the test adapter box 2 is raised and lowered relative to the installation platform 1. This realizes the nearby transfer of test points on the test specimen on the installation platform 1, which meets the connection and maintenance operation of the test specimen interface. At the same time, it can make full use of space, so that both the installation platform 1 and the test adapter box 2 can be placed close to the test specimen, effectively avoiding the problem of space limitation near the test specimen. Therefore, compared with related technologies, this utility model takes into account the needs of high-altitude installation of the test interface and nearby transfer of test points, which is convenient for installation and maintenance and occupies little space.

[0043] It is understood that the test adapter box 2 is slidably connected to the top opening of the receiving cavity 11. In other words, the test adapter box 2 and the top opening of the receiving cavity 11 are slidably engaged. This means that the test adapter box 2 can extend or retract from the top opening of the receiving cavity 11 relative to the top of the mounting platform 1. In the first position, the test adapter box 2 is housed in the receiving cavity 11, while in the second position, the test adapter box 2 is positioned above the top of the mounting platform 1. This allows for the connection and maintenance of the test points of the test specimen and the interface on the test adapter box 2 from the top of the mounting platform 1. This satisfies the requirements for the extraction and testing of test points for various specifications of test specimens. It has strong applicability and operability, a simple overall structure, and is beneficial for the pre-test preparation work of gas turbine component testing. It also improves test accuracy, shortens the overall test cycle, improves test quality, and reduces test costs.

[0044] like Figure 1 and Figure 2As shown, in some embodiments, the mounting platform 1 includes a platform body 12 and a cover plate 13. The platform body 12 is provided with a receiving cavity 11. The cover plate 13 is pivotally mounted on the top of the platform body 12. The cover plate 13 has a first critical state of opening the top opening of the receiving cavity 11 and a second critical state of closing the top opening of the receiving cavity 11.

[0045] Understandably, the cover plate 13 can seal the top opening of the receiving cavity 11 when the test adapter box 2 is stored in the receiving cavity, so as to isolate the test adapter box 2 from the external environment and ensure the service life of the test adapter box 2. When the test piece needs to be tested, the cover plate 13 is opened so that the test adapter box 2 can be extended from the top opening of the receiving cavity 11, making the testing operation convenient.

[0046] For example, as shown in the figure, the platform body 12 can be fixedly installed near the test piece. The platform body 12 can be formed by multiple side plates surrounding a frame, and a top plate and a cover plate 13 installed on the top of the frame. At this time, a receiving cavity 11 is constructed between the frame and the top plate. The cover plate 13 is perpendicular to the top plate in a first critical state to open the top opening of the receiving cavity 11, and in a second critical state, it is flush with the top plate to cover the top opening of the receiving cavity 11. In other words, the cover plate 13 is lowered into place, and the top of the installation platform 1 is in a flat state. The top plate provides operating space for operators to perform high-level installation work on the platform body 12 for the test interface.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the cover plate 13 includes a first plate 131 and a second plate 132. Both the first plate 131 and the second plate 132 are pivotally connected to the top of the platform body 12. The first plate 131 and the second plate 132 are spaced apart along a first direction in a first critical state and overlap along the height direction of the platform body 12 in a second critical state. The first direction is perpendicular to the height direction of the platform body 12.

[0048] Specifically, the first direction can be the front-to-back direction in the figure. The height direction of the platform body 12 can be the up-to-down direction in the figure. When the cover plate 13 is in the first critical state, the first plate 131 can be located in front of the second plate 132, and the first plate 131 and the second plate 132 are parallel and spaced apart in the front-to-back direction.

[0049] like Figure 2As shown, in some embodiments, the first plate 131 is provided with a notch 1311, that is, the edge of the first plate 131 is formed with a notch. The cover plate 13 also has an intermediate state between a first critical state and a second critical state. When the cover plate 13 is in the intermediate state, the first plate 131 covers the top opening of the receiving cavity 11. The notch 1311 and the top of the platform body 12 define a channel opening 14. The lifting assembly 3 is slidably connected to the channel opening 14 and can extend or retract relative to the receiving cavity 11. In other words, the lifting assembly 3 and the channel opening 14 are slidably engaged. The second plate 132 forms an angle with the first plate 131. The area of ​​the channel opening 14 is smaller than the area of ​​the top opening of the receiving cavity 11.

[0050] For example, as shown in the figure, when the cover plate 13 is in the middle state, the first plate 131 can press on the top of the platform body 12, while the second plate 132 is at a 90-degree angle to the first plate 131, or in other words, the second plate is located above the top of the platform body 12 and is perpendicular to the first plate 131.

[0051] It is understandable that designing the cover plate 13 as a structure in which the first plate 131 and the second plate 132 cooperate, and the first plate 131 is provided with a notch 1311, can partially cover the top opening of the receiving cavity 11 by the first plate 131 after the test adapter box 2 extends out of the top opening of the receiving cavity 11, thereby reducing the communication area between the receiving cavity 11 and the external environment. Only the part of the test adapter box 2 and the lifting assembly 3 extending out of the channel opening 14 is exposed to the external environment, which helps to protect the remaining electrical components in the receiving cavity 11 and further ensures the normal operation performance and service life of the entire test installation device 100.

[0052] like Figure 3 As shown, in some embodiments, the mounting platform 1 further includes a first lifter 15 and a second lifter 16. Both the first lifter 15 and the second lifter 16 are connected to the receiving cavity 11, that is, both the first lifter 15 and the second lifter 16 are installed in the receiving cavity 11 to reduce the corrosive damage to both from the external environment and ensure their service life. The first lifter 15 is drivenly connected to the first plate 131, and the second lifter 16 is drivenly connected to the second plate 132.

[0053] It is understandable that the automatic lifting of the cover plate 13 can be achieved through the first lifter 15 and the second lifter 16, which further optimizes the performance of the test installation device 100 and improves the degree of automation.

[0054] For example, the first lifting device 15 and the second lifting device 16 are both telescopic cylinders. The telescopic cylinder is not limited to one of electric cylinder, pneumatic cylinder, hydraulic cylinder and oil cylinder. In this case, the cylinder body of the telescopic cylinder can be connected to the inner circumferential surface of the accommodating cavity, and the piston rod of the telescopic cylinder can be pivotally connected to the bottom surface of the first plate 131 or the second plate 132 (i.e., hinged).

[0055] like Figure 3 As shown, in some embodiments, the lifting assembly 3 includes a third lifter 31, which is connected to the receiving cavity 11 and is drivenly connected to the test adapter box 2, so that the test adapter box 2 can be extended or retracted relative to the receiving cavity 11 by the third lifter 31. Similarly, the third lifter 31 can be used to realize the automatic lifting of the test adapter box 2 relative to the platform body 12.

[0056] For example, the third lifter 31 can be a scissor lift. Taking the figure as an example, the top of the scissor lift can be installed at the bottom middle position of the test adapter box 2, and the bottom of the scissor lift can be installed in the receiving cavity 11. It can be folded or unfolded along the height direction of the platform body 12 to ensure the smooth lifting and lowering of the test adapter box 2 to the greatest extent.

[0057] It should be noted that a lifting control box can also be installed in the receiving cavity 11. The first lifter 15, the second lifter 16 and the third lifter 31 can all send function signals to the control module in the lifting control box via wireless control (such as remote control). The control module outputs control voltage to the corresponding relay, so that each lifter (first lifter 15, second lifter 16 and third lifter 31) is powered on and starts to work. After each lifter has reached its position, the execution result of the action will be fed back through the limit switch installed on the side of the platform so that the lifter stops moving.

[0058] like Figure 3 As shown, in some embodiments, the test installation device 100 further includes cables, and the test adapter box 2 is connected to the cables to transmit test parameter information.

[0059] The lifting assembly 3 also includes a cable chain 32, the first end of which is connected to the receiving cavity 11, and the second end of which is connected to the test adapter box 2. The cable is installed on the cable chain 32 and can move relative to the receiving cavity 11 with the cable chain 32.

[0060] It is understandable that by connecting the cable to the cable chain 32, the cable can be automatically extended or retracted by the cable chain 32 to ensure the smooth conduct of the transfer test of the test adapter box 2.

[0061] like Figure 3As shown, in some embodiments, the test installation device 100 further includes a frame 4 and a tension roller 5. The frame 4 is installed in the receiving cavity 11, and the tension roller 5 is rotatably connected to the cable chain 32 and slidably connected to the frame 4. The tension roller 5 can adjust the tension of the cable chain 32.

[0062] Specifically, a sliding guide rail can be installed on the frame 4 along its extension direction, and a telescopic cylinder can be installed on the frame 4. The tensioning roller 5 can be slidably connected to the sliding guide rail along the extension direction of the frame 4 via a slider. The piston rod of the telescopic cylinder is connected to the slider, so that the telescopic cylinder pushes and pulls the tensioning roller 5 to adjust the position of the tensioning roller 5 on the frame 4, thereby changing the tension of the cable chain 32. The tensioning roller 5 can be a damping roller.

[0063] like Figure 3 As shown, in some embodiments, the test installation apparatus 100 further includes a conveying device 6 located below the frame 4 and used to convey cables to effectively prevent cables from dragging and rubbing against the ground. The conveying direction of the conveying device 6 may be consistent with the sliding direction of the tensioning roller 5. The conveying device 6 may be, for example, a conveying roller.

[0064] like Figure 4 As shown, in some embodiments, the test adapter box 2 is used to transfer information on at least one of the parameters of the test specimen, including temperature, static pressure, dynamic pressure, and strain.

[0065] like Figure 4 As shown, in some embodiments, the test adapter box 2 includes a box body 21 and a pressure backflush controller 22. The box body 21 is provided with at least one of a temperature measurement adapter panel 211, a pressure measurement adapter panel 212 and a dynamic measurement adapter panel 213. The pressure backflush controller 22 is installed in the box body 21 and is used to control the operation of the pressure test backflush system.

[0066] Specifically, the temperature measurement adapter panel 211 can be a thermocouple adapter panel for quick connection of various types of thermocouples required for testing. The pressure measurement adapter panel 212 can be a pressure measurement adapter panel for quick connection of pressure measuring tubes required for testing. The dynamic measurement adapter panel 213 can be composed of a preamplifier mounting box and adapter panels for stress-strain, dynamic pressure, and vibration signal cables, for quick connection of dynamic test cables required for testing. Each adapter panel is modularly designed for easy replacement and maintenance.

[0067] In addition, the pressure backflush controller 22 is the controller of the pressure test backflush system. It can be integrated into the test adapter box 2 and can also have a lifting function. For example, the lifting action can be triggered by the up / down button on the test adapter box 2. When it is raised to the right position, the pressure backflush command can be sent through the control signal of the pressure backflush controller 22 to backflush the pressure pipeline before pressure measurement to ensure accurate measurement.

[0068] like Figure 5 As shown, a test platform 10 for a gas turbine test piece according to an embodiment of the present invention includes a test installation device 100 and a test instrument unit 200. The test installation device 100 is arranged adjacent to the test piece. The test installation device 100 is the test installation device 100 of any of the above embodiments.

[0069] The technical advantages of the test platform 10 for gas turbine test pieces according to the present invention are the same as those of the test installation device 100 for gas turbine test pieces described above, and will not be repeated here.

[0070] like Figure 5 As shown, in some embodiments, the test platform 10 further includes a cable tray 7 located between the test installation device 100 and the test instrument unit 200, with at least a portion of the cables mounted on the cable tray 7.
