Description

Technical Field

[0001] The present invention belongs to the technical field of steam turbines, and particularly relates to an auxiliary installation tool for high-sealing steam seals of steam turbines. Background Art

[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated air flow and then jets onto the blades, causing the rotor equipped with the blade row to rotate and perform external work at the same time. There is a cylinder on the steam turbine, and there is a high-sealing steam seal inside the cylinder. The steam seal is integrally circular and is composed of two semi-circular parts. In the actual installation process, the cylinder body is also composed of two semi-circular rings and then assembled together. It is necessary to plug the semi-circular steam seal into the semi-circular cylinder. In the prior art, it is recorded in the auxiliary installation tool for high-sealing steam seals of steam turbines with the application number 202111281610.X that has been published, "Hang the steam seal on the groove 6 and the hanging groove 19, and then move it to the cylinder of the steam turbine." Among them, after the steam seal is hung on the groove, due to the lack of a positioning structure, it is impossible to ensure that the middle position of the steam seal piece corresponds to the groove, so that the position of the steam seal piece in the groove is inconsistent each time, reducing the accuracy of the installation of the steam seal piece. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary installation tool for high-sealing steam seals of steam turbines to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] An auxiliary installation tool for high-sealing steam seals of steam turbines includes a bottom plate. A vertical plate member is connected to the middle of the top of the bottom plate. A steam seal piece is provided on one side of the vertical plate member. A pressing module is provided above the steam seal piece. The pressing module includes a pressing frame body, which is located above the steam seal piece. An adjusting module is provided below the steam seal piece. The adjusting module includes an adjusting plate member, a device notch, and a contact switch. The adjusting plate members are symmetrically arranged on both sides below the steam seal piece. The device notch is opened in the middle of one side of the top of the adjusting plate member. The contact switch is embedded in the device notch. A cross bar is provided at the bottom of the steam seal piece. An installation module is connected between one end of the cross bar and the vertical plate member. The installation module includes a knocking motor, a knocking frame body, and a moving plate member. The knocking motor is located below the steam seal piece. The middle of the bottom of the knocking frame body is connected to the output shaft of the top of the knocking motor. The moving plate member is arranged on one side of the vertical plate member, and the cross bar is connected to the moving plate member. The bottom surface of the moving plate member is slidably matched with the bottom plate.

[0006] Preferably, the pressing-down module further includes an extended plate member, a first-stage electric telescopic rod, a transverse plate member, and a first-stage pressure sensor. The first-stage pressure sensor is connected to the middle of the top of the pressing-down frame body. The transverse plate member is connected to the top of the first-stage pressure sensor. The first-stage electric telescopic rod is arranged on the top of the transverse plate member, and the output end of the bottom of the first-stage electric telescopic rod is connected to the middle of the top of the transverse plate member. The extended plate member is connected to the top of the first-stage electric telescopic rod, and one end of the extended plate member is connected to the top of one side of the vertical plate member. The output end of the first-stage electric telescopic rod drives the transverse plate member, the first-stage pressure sensor, and the pressing-down frame body to descend, restricting the gland segment between the pressing-down frame body and the cross bar, and completing the secondary positioning of the gland segment.

[0007] Preferably, the adjusting module further includes a square plate member, a double-shaft motor, and a rotating shaft. The square plate member is connected to one side of the vertical plate member, and the knocking motor is connected to the top of the square plate member through a positioning bolt. The double-shaft motor is connected to the bottom of the square plate member through a positioning bolt. The rotating shafts are symmetrically arranged on both sides of the double-shaft motor, and one end of the rotating shaft is connected to the output end of the double-shaft motor. The double-shaft motor drives the rotating shafts on both sides to rotate, making the two adjusting plate members rotate and approach the gland segment until the two contact switches respectively contact the bottom end of the gland segment, performing the three-time positioning of the gland segment, that is, completing the centering positioning of the gland segment.

[0008] Preferably, the adjusting module further includes an outer sleeve pipe fitting and a second-stage electric telescopic rod. The outer sleeve pipe fitting is sleeved and connected to the outer wall of the rotating shaft. The second-stage electric telescopic rod is arranged between the adjusting plate member and the outer sleeve pipe fitting. The second-stage electric telescopic rod is connected to the outer sleeve pipe fitting, and the output end of the second-stage electric telescopic rod is connected to the adjusting plate member. According to the radius of the gland segment, the second-stage electric telescopic rod is turned on, so that the output end of the second-stage electric telescopic rod drives the adjusting plate member to move until the distance from the end of the adjusting plate member far from the second-stage electric telescopic rod to the central axis of the outer sleeve pipe fitting is consistent with the radius of the gland segment, ensuring the centering adjustment effect of the subsequent adjusting plate member on the gland segment.

[0009] Preferably, the installation module further includes a fixing ring, a third-stage electric telescopic rod, an arc plate member, a second-stage pressure sensor, arc clamping pieces, and a limiting circular plate.

The second-stage pressure sensor is connected between the arc clamping pieces and the arc plate member. The limiting circular plate is connected to one end of the cross bar far from the moving plate member. The gland segment is located between the limiting circular plate and the arc clamping pieces. The output end of the third-stage electric telescopic rod drives the arc plate member, the second-stage pressure sensor, and the arc clamping pieces to move towards the gland segment, clamping the gland segment between the arc clamping pieces and the limiting circular plate.

[0010] Preferably, the installation module further includes a sliding notch, a sliding block, a first-stage driving motor, a first-stage driving lead screw, and a blocking plate member. The sliding notch is formed in the lower part inside the vertical plate member and penetrates through the vertical plate member. The sliding block is slidably fitted in the sliding notch.

The outer wall of the first-stage driving lead screw is threadedly connected to the moving plate member by external threads. The blocking plate member is connected to the end of the first-stage driving lead screw away from the first-stage driving motor. The first-stage driving motor drives the first-stage driving lead screw to rotate, driving the moving plate member to translate on the top of the bottom plate. The arrangement of the blocking plate member prevents the moving plate member from detaching from the first-stage driving lead screw.

[0011] Preferably, the installation module further includes strip-shaped plate members symmetrically connected to the lower sides of both sides of the moving plate member, and the strip-shaped plate members are slidably fitted with the vertical plate member to restrict the moving plate member and prevent the moving plate member from rotating as the first-stage driving lead screw rotates.

[0012] Preferably, the installation module further includes a first-stage assembly plate member, a second-stage assembly plate member, a second-stage driving motor, a second-stage driving lead screw, and a lifting plate member. The first-stage assembly plate member is connected to the top of the bottom plate and is connected to the vertical plate member. The second-stage assembly plate member is arranged above the first-stage assembly plate member, and the bottom surface of the second-stage assembly plate member is flush with the top surface of the sliding notch. The second-stage assembly plate member is connected to the vertical plate member. The lifting plate member is located between the first-stage assembly plate member and the second-stage assembly plate member. The second-stage driving motor is connected to the top of the second-stage assembly plate member by a positioning bolt. The top end of the second-stage driving lead screw is connected to the output end at the bottom of the second-stage driving motor, and the bottom end of the second-stage driving lead screw sequentially penetrates through the second-stage assembly plate member, the lifting plate member, and is bearing-connected to the first-stage assembly plate member. The outer wall of the second-stage driving lead screw is threadedly connected to the lifting plate member by external threads. The first-stage driving motor is connected to the lifting plate member by a positioning bolt. The second-stage driving motor drives the second-stage driving lead screw to rotate, so that the lifting plate member drives the first-stage driving motor, the sliding block, and the moving plate member to lift.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is in use, the gland segment is placed on the top of the cross bar. Through the arc-shaped clamping piece and the limiting circular plate, the gland segment can be restricted and fixed, so as to be applicable to gland segments of different thicknesses. And through the second-stage pressure sensor, while ensuring the clamping effect on the gland segment, the gland segment can be moved and adjusted. The adjustment module automatically adjusts the gland segment to ensure that each gland segment can be centered and clamped, ensuring the accuracy during the installation of the gland segment. Then, through the knocking module, the gland segment is transferred to the cylinder and installed. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shafts 56 are symmetrically arranged on both sides of the double-shaft motor 55, and one end of the rotating shaft 56 is connected to the output end of the double-shaft motor 55. The double-shaft motor 55 drives the rotating shafts 56 on both sides to rotate, so that the two groups of adjusting plate members 51 rotate and approach the steam seal piece 3 until the two contact switches 53 respectively contact the bottom end of the steam seal piece 3 to perform the three-time positioning of the steam seal piece 3, that is, to complete the centering positioning of the steam seal piece 3.

[0024] Reference Figure 1 and Figure 2As shown, the adjustment module 5 further includes an outer sleeve pipe fitting 57 and a secondary electric telescopic rod 58. The outer sleeve pipe fitting 57 is sleeved and connected to the outer wall of the rotating shaft 56.

The secondary electric telescopic rod 58 is connected to the outer sleeve pipe fitting 57, and the output end of the secondary electric telescopic rod 58 is connected to the adjustment plate member 51. According to the radius of the gland segment 3, the secondary electric telescopic rod 58 is activated, so that the output end of the secondary electric telescopic rod 58 drives the adjustment plate member 51 to move until the distance from the end of the adjustment plate member 51 away from the secondary electric telescopic rod 58 to the central axis of the outer sleeve pipe fitting 57 is consistent with the radius of the gland segment 3, ensuring the subsequent centering adjustment effect of the adjustment plate member 51 on the gland segment 3.

[0025] Reference Figures 1 - 5 As shown, the installation module 7 further includes a fixing ring 74, a tertiary electric telescopic rod 75, an arc plate member 76, a secondary pressure sensor 77, an arc clamping piece 78 and a limiting circular plate 79.

The strip plate member 715 is symmetrically connected to the lower sides of both sides of the moving plate member 73, and the strip plate member 715 is slidably engaged with the vertical plate member 2 to limit the moving plate member 73 and prevent the moving plate member 73 from rotating as the first-stage driving lead screw 713 rotates.

The first-stage driving motor 712 is connected to the lifting plate member 720 by positioning bolts. The second-stage driving motor 718 drives the second-stage driving lead screw 719 to rotate, so that the lifting plate member 720 drives the first-stage driving motor 712, the sliding block 711, and the moving plate member 73 to move up and down.

[0029] Working principle: According to the radius of the gland segment 3, the second-level electric telescopic rod 58 is opened, and the output end of the second-level electric telescopic rod 58 drives the adjusting plate member 51 to move until the distance from the end of the adjusting plate member 51 away from the second-level electric telescopic rod 58 to the central axis of the outer sleeve pipe member 57 is the same as the radius of the gland segment 3, ensuring the subsequent centering adjustment effect of the adjusting plate member 51 on the gland segment 3. Place the gland segment 3 on the top of the cross bar 6 and make the gland segment 3 behind the limiting circular plate 79. Open the third-level electric telescopic rod 75, and the output end of the third-level electric telescopic rod 75 drives the arc-shaped plate member 76, the second-level pressure sensor 77, and the arc-shaped clamping piece 78 to move towards the gland segment 3 until the gland segment 3 is clamped between the arc-shaped clamping piece 78 and the limiting circular plate 79. The second-level pressure sensor 77 monitors the pressure of the arc-shaped clamping piece 78 clamping the gland segment 3 to prevent the clamping force from being too large and affecting the subsequent adjustment of the gland segment 3, and to prevent the clamping force from being too small and unable to ensure the stability of the gland segment 3. When the clamping force of the arc-shaped clamping piece 78 and the limiting circular plate 79 on the gland segment 3 reaches the preset value, the second-level pressure sensor 77 transmits the data to the peripheral device terminal. The peripheral device terminal receives the data and controls the third-level electric telescopic rod 75 to close and the first-level electric telescopic rod 43 to open, completing the preliminary positioning of the gland segment 3. The output end of the first-level electric telescopic rod 43 drives the transverse plate member 44, the first-level pressure sensor 45, and the downward pressing frame body 41 to descend. The first-level pressure sensor 45 monitors the force of the downward pressing frame body 41 pressing the gland segment 3 to prevent the downward pressing force of the downward pressing frame body 41 from being too large and affecting the subsequent adjustment of the gland segment 3, and to prevent the downward pressing force of the downward pressing frame body 41 from being too small and unable to ensure the stability of the gland segment 3. When the force of the downward pressing frame body 41 pressing the gland segment 3 reaches the preset value, the first-level pressure sensor 45 transmits the data to the peripheral device terminal. The peripheral device terminal receives the data and controls the first-level electric telescopic rod 43 to close and the double-axis motor 55 to open, thereby restricting the gland segment 3 between the downward pressing frame body 41 and the cross bar 6, completing the secondary positioning of the gland segment 3. The double-axis motor 55 drives the rotating shafts 56 on both sides to rotate, making the two groups of adjusting plate members 51 rotate and approach the gland segment 3 until the two groups of contact switches 53 respectively contact the bottom end of the gland segment 3, performing the three-time positioning of the gland segment 3, that is, completing the centering positioning of the gland segment 3. The two groups of contact switches 53 transmit signals to the peripheral device terminal. The peripheral device terminal receives the signals and controls the double-axis motor 55 to close and the first-level electric telescopic rod 43 to open. The output end of the first-level electric telescopic rod 43 drives the transverse plate member 44, the first-level pressure sensor 45, and the downward pressing frame body 41 to rise until the output end of the first-level electric telescopic rod 43 is completely retracted. The first-level electric telescopic rod 43 transmits signals to the peripheral device terminal. The peripheral device terminal receives the signals and controls the first-level electric telescopic rod 43 to close and the first-level driving motor 712 to open. The first-level driving motor 712 drives the first-level driving lead screw 713 to rotate. Since the outer wall of the first-level driving lead screw 713 is threadedly connected to the moving plate member 73 through external threads, the rotating first-level driving lead screw 713,Drive the moving plate 73 to slide on the top of the bottom plate 1, so that the moving plate 73 moves away from the vertical plate 2, thereby transferring the gland strip 3 on the top of the cross bar 6 to the cylinder. After the transfer is completed, the operator turns off the first-stage drive motor 712 and turns on the second-stage drive motor 718. The second-stage drive motor 718 drives the second-stage drive lead screw 719 to rotate. Since the outer wall of the second-stage drive lead screw 719 is connected to the lifting plate 720 through external threads, the rotating second-stage drive lead screw 719 drives the lifting plate 720 to rise. When the gland strip 3 rises to the installation position of the gland strip 3 on the inner wall of the cylinder, the operator turns off the second-stage drive motor 718. After the second-stage drive motor 718 is turned off, the second-stage drive motor 718 sends a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the knocking motor 71 to turn on. The output end of the knocking motor 71 drives the knocking body 72 to knock from the inner wall of the gland strip 3, knocking the gland strip 3 to the installation position of the gland strip 3 on the inner wall of the cylinder. After the installation of the gland strip 3 is completed, the operator turns off the knocking motor 71 and turns on the second-stage drive motor 718. The second-stage drive motor 718 drives the second-stage drive lead screw 719 to rotate, so that the second-stage drive lead screw 719 drives the lifting plate 720 to descend, so that the moving plate 73 descends along with the lifting plate 720. After the lifting plate 720 descends and contacts the first-stage assembly plate 716, the lifting plate 720 cannot descend, so that the second-stage drive lead screw 719 cannot continue to rotate. The second-stage drive motor 718 senses and sends a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the second-stage drive motor 718 to turn off and the first-stage drive motor 712 to turn on. The first-stage drive motor 712 drives the first-stage drive lead screw 713 to rotate, and the first-stage drive lead screw 713 drives the moving plate 73 to move until the moving plate 73 contacts the vertical plate 2. At this time, the moving plate 73 cannot continue to move, and the first-stage drive lead screw 713 cannot continue to rotate. The first-stage drive motor 712 senses and sends a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the first-stage drive motor 712 to turn off and the third-stage electric telescopic rod 75 to turn on. The output end of the third-stage electric telescopic rod 75 drives the arc plate 76, the second-stage pressure sensor 77 and the arc clamping piece 78 to move away from the limiting circular plate 79 until the output end of the third-stage electric telescopic rod 75 is completely contracted. The third-stage electric telescopic rod 75 sends a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the third-stage electric telescopic rod 75 to turn off and the double-shaft motor 55 to turn on. The double-shaft motor 55 drives the rotating shaft 56 to drive the outer sleeve pipe 57 to rotate, so that the adjusting plate 51 rotates downward until the adjusting plate 51 contacts the bottom plate 1. The adjusting plate 51 cannot continue to rotate. After the double-shaft motor 55 senses that the rotating shaft 56 cannot continue to rotate, the double-shaft motor 55 sends a signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the double-shaft motor 55 to turn off. The reset adjusting plate 51 is not likely to affect the placement of the subsequent new gland strip 3.,
