The installation aid of the gas turbine, the mobile generator set and the installation method of the gas turbine provided by the embodiment of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 3, embodiments of the present application disclose a mounting aid for a gas turbine 110, which can be used to assemble the gas turbine 110 with a gearbox or generator, and optionally, the gas turbine 110 can be connected with the gearbox or generator through a power output shaft 320. The mounting aid disclosed in the embodiments of the present application may include a bracket 120, a lifting assembly, and a support assembly 310.

The bracket 120 may provide a mounting base for other components included in the mounting aid, and may allow the mounting aid to be stably fixed at a predetermined position, which may be in a quiet compartment of a vehicle, that is, the mounting aid disclosed in the embodiment of the present application may be applied to a mobile power generator set. The support 120 has a length direction, and because the gas turbine 110 is generally a long-axis structure, when the support 120 is set to have a length direction structure, the hoisting requirement of the gas turbine 110 can be met, and the size of the support 120 in other directions can be reduced, so that the whole installation auxiliary tool is smaller, and the whole installation auxiliary tool can be better adapted to a narrow installation space. In addition, the support 120 can adopt a frame structure, so that the support area of the support 120 can be increased, the stability of the support is improved, the weight of the support can be reduced, and the support can be better applied to a mobile generator set.

The number of the hoisting assemblies is multiple, the hoisting assemblies may have the same or different structures, and different hoisting assemblies may be connected to different positions of the gas turbine 110, so as to hoist the gas turbine 110 more stably. The hoisting assembly comprises a sling 130, a diverting pulley and a driving mechanism, the sling 130 is a flexible structure, optionally, the sling 130 can be a steel wire rope, the diverting pulley and the driving mechanism are both arranged on the bracket 120, and the diverting pulley can change the extending direction of the sling 130, so that the sling 130 is conveniently connected with the driving mechanism. A first end of the sling 130 is connected to the drive mechanism and a second end of the sling 130 is adapted to be connected to the gas turbine 110, the second end passing over a diverting pulley, i.e. the second end of the sling 130 may be passed around the diverting pulley and connected to the gas turbine 110. Alternatively, there may be only one diverting pulley, for example one diverting pulley may be arranged on top of the carriage 120; the driving mechanism may be disposed at the bottom of the bracket 120, so that the center of gravity of the auxiliary mounting tool is moved down as much as possible to ensure stability thereof, and the driving mechanism may employ a hydraulic cylinder or an air cylinder, and the suspension cable 130 may be driven to slide relative to the diverting pulley by extending and retracting a cylinder rod of the hydraulic cylinder or the air cylinder, so as to apply an acting force to the gas turbine 110.

The support assembly 310 is disposed on the support frame 120, the support assembly 310 is used for supporting the gas turbine 110, and at least two lifting assemblies are disposed on two sides of the support assembly 310 in the length direction of the support frame 120, so that the lifting position and the supporting position of the gas turbine 110 are more dispersed, the gas turbine 110 can be lifted more stably, and the support assembly 310 can be closer to the center of the gas turbine 110, so that the support assembly 310 can support the gas turbine 110 more effectively. The support assembly 310 may contact the gas turbine 110 after the position adjustment of the gas turbine 110 is completed, thereby supporting the gas turbine 110, so that the gas turbine 110 may be more reliably kept fixed during the operation, and at the same time, once the position of the gas turbine 110 is suddenly lowered due to an accident during the hoisting process, the support assembly 310 may support the gas turbine 110, thereby preventing the gas turbine 110 from falling.

The embodiment of the present application provides an auxiliary installation tool for a gas turbine 110, which can hoist the gas turbine 110 by a plurality of hoisting assemblies, and a driving mechanism of the auxiliary installation tool can drive a sling 130 to move, so as to adjust the position of the gas turbine 110, so that the gas turbine 110 is aligned with a power output shaft 320, and a support assembly 310 can support the gas turbine 110. After the installation auxiliary tool is adopted, the driving force can be output through the driving mechanism, so that the position of the gas turbine 110 can be adjusted, an operator does not need to directly apply acting force to the gas turbine 110 to change the position of the gas turbine, the installation auxiliary tool can reduce the manual participation degree when the gas turbine 110 is installed, the working strength of the operator is reduced, the position adjusting operation of the gas turbine 110 is simplified, meanwhile, the driving mechanism can more accurately drive the sling 130 to move, the position adjustment of the gas turbine 110 can be completed in a short time, the installation time of the gas turbine 110 is shortened, meanwhile, the centering performance of the gas turbine 110 is improved, and the gas turbine 110 is prevented from colliding with other parts.

If the driving mechanism is configured to have a cylinder rod, the movement amount of the suspension cable 130 is related to the telescopic amount of the cylinder rod, which is limited by the installation space, and thus the movement amount of the suspension cable 130 is also greatly limited, so that the position adjustment range of the gas turbine 110 is limited. Based on this, in other embodiments, the driving mechanism includes a driving source 140 and a winding member 150, alternatively, the driving source 140 may be a motor, the winding member 150 may be disposed on a winding shaft 160, the driving source 140 may be connected to the winding member 150 through the winding shaft 160, the first end of the sling 130 is connected to the winding member 150, and the driving source 140 drives the winding member 150 to rotate so that the sling 130 is wound on the winding member 150 or unwound from the winding member 150. In this embodiment, the driving source 140 can output a rotational driving force to drive the winding element 150 to rotate, and during the rotation of the winding element 150 along the first direction, the suspension cable 130 is gradually wound around the winding element 150, and the suspension cable 130 is gradually shortened; when the winding member 150 rotates in a second direction opposite to the first direction, the sling 130 is gradually unwound from the winding member 150, and the sling 130 is gradually extended. Since the winding member 150 does not require an extra space for the rotation thereof, and the slings 130 can be greatly wound around the winding member 150, the movement range of the slings 130 is larger, thereby adjusting the position of the gas turbine 110 in a larger range.

Further, the driving mechanism further comprises a lead screw 170, a sliding block 180 and a guide wheel 190, the lead screw 170 is parallel to the winding part 150, the sliding block 180 is arranged on the lead screw 170, the sliding block 180 is in threaded fit with the lead screw 170, the guide wheel 190 is connected with the sliding block 180, the first end of the guide wheel 190 penetrates through the lead screw 170, and the lead screw 170 is used for driving the guide wheel 190 to move along the extending direction of the lead screw 170 through the sliding block 180. Optionally, a driving member may be additionally added, and the driving member may be connected to the lead screw 170 so as to drive the lead screw 170 to rotate. When the lead screw 170 rotates, the slider 180 can move along the extending direction of the lead screw 170, and then the guide wheel 190 is driven to move along the extending direction of the lead screw 170, and the guide wheel 190 can apply acting force to the sling 130, so that the sling 130 is wound at different positions of the winding member 150, and the sling 130 is prevented from gradually accumulating at the same position of the winding member 150 and occupying too large space.

Optionally, the installation aid may further include a first mounting bracket 210, a second mounting bracket 220, and a third mounting bracket 230, which may be sequentially arranged at intervals along a length direction of the bracket 120, the winding shaft 160 and the lead screw 170 may be connected to the first mounting bracket 210 and the second mounting bracket 220 through bearings, so as to implement installation of the winding member 150 and the lead screw 170, the driving source 140 may be disposed on the bracket 120 through the third mounting bracket 230, and the driving source 140 may be connected to the winding shaft 160 through the coupling 240.

As mentioned above, the driving member may be additionally provided to drive the screw 170 to rotate, but such an arrangement would increase the number of parts included in the installation aid, thereby resulting in an excessively high cost of the installation aid and an excessively complicated operation. To solve these problems, the driving mechanism optionally further comprises a transmission member 250, and the winding member 150 is connected to the lead screw 170 through the transmission member 250. That is to say, after the driving source 140 drives the winding member 150 to rotate, the winding member 150 can further drive the screw 170 to rotate through the transmission member 250, so that the same driving source 140 can drive the winding member 150 and the screw 170 to rotate simultaneously, thereby reducing the number of parts included in the installation aid, and reducing the cost and the operation difficulty of the installation aid.

The transmission member 250 may include gears, and the end of the winding shaft 160 and the end of the lead screw 170 may be provided with gears that are engaged with each other to transmit the driving force. Since a certain distance is required between the winding member 150 and the lead screw 170 to ensure that the suspension cable 130 can be wound on the winding member 150 in a large scale, the gears installed on the winding shaft 160 and the lead screw 170 must be large enough to transmit the driving force, which results in an excessive space occupied by the installation aid. Therefore, in order to reduce the space occupied by the installation assistant tool, the transmission member 250 may include a timing belt, which may be wound around the winding shaft 160 and the lead screw 170 at the same time, so that the winding member 150 drives the lead screw 170 to rotate synchronously through the timing belt. No matter how large the distance between the winding member 150 and the lead screw 170 is, the thickness of the timing belt can be set to be smaller, so that the space occupied by the timing belt is smaller, thereby reducing the space occupied by the installation assistant tool. In addition, the timing belt can better ensure that the winding element 150 and the lead screw 170 rotate synchronously, so that the suspension cable 130 is wound on the winding element 150 more evenly.

The extending direction of the winding member 150 may be flexibly selected, for example, the extending direction of the winding member 150 may be perpendicular to the length direction of the bracket 120, but considering that there is a sufficient space in the length direction of the bracket 120, the extending direction of the winding member 150 may be parallel to the length direction of the bracket 120, thereby facilitating the arrangement of the winding member 150. At this time, the driving source 140 and the lead screw 170 also extend in the length direction of the bracket 120, and thus this embodiment also facilitates the provision of the driving source 140 and the lead screw 170.

When the number of diverting pulleys is only one, the number of changes of direction of the hoisting rope 130 is small, thus making the layout of the hoisting rope 130 and other parts difficult. In view of this, in other embodiments, the number of the diverting pulleys is multiple, and the diverting pulleys include a first pulley 260, a second pulley 270 and a third pulley 280, the first pulley 260 may be disposed on the top of the bracket 120 through a pulley mounting bracket 290, the driving mechanism is disposed on the bottom of the bracket 120, the second pulley 270 and the third pulley 280 are disposed between the first pulley 260 and the driving mechanism, the second pulley 270 and the third pulley 280 may be disposed on the bracket 120 through the first mounting bracket 210, and the second end sequentially passes through the third pulley 280, the second pulley 270 and the first pulley 260. After the arrangement, the second end of the sling 130 can change its extending direction when passing through the third pulley 280, the second pulley 270 and the first pulley 260, so that the layout of the components included in the auxiliary tool can be easily installed. In an alternative embodiment, the second pulley 270 may be located between the support member 310 and the third pulley 280, and the first pulley 260 may be located above the second pulley 270, such that the second end of the sling 130 passes through the third pulley 280, then horizontally passes into the second pulley 270, further passes out of the second pulley 270, and vertically passes into the first pulley 260, which may make the sling 130 more compact to control the space occupied by the installation aid.

In an alternative embodiment, the supporting assembly 310 includes a mounting seat 311, a supporting member 312, a first clamping member and a second clamping member, and the first clamping member and the second clamping member may have the same structure or different structures. The mounting seat 311 is disposed on the bracket 120, the supporting member 312, the first clamping member and the second clamping member are distributed in the same plane, the plane may be perpendicular to the axial direction of the gas turbine 110, the supporting member 312, the first clamping member and the second clamping member form a clamping space, the clamping space is used for accommodating the gas turbine 110, the first clamping member is opposite to the second clamping member, and the height of the first clamping member and the height of the second clamping member are both greater than the height of the supporting member 312. The support member 312 may be positioned under the gas turbine 110 to support the gas turbine 110, and the first and second clamping members may act on opposite sides of the gas turbine 110 to clamp the gas turbine 110 to prevent the gas turbine 110 from shaking. The first and second clamps herein may improve the support stability of the gas turbine 110 compared to supporting only the gas turbine 110, making the gas turbine 110 less prone to play.

Alternatively, the mounting seat 311 may be mounted on the bracket 120 by a mounting bolt, and the supporting member 312, the first clamping member and the second clamping member may be detachably mounted on the mounting seat 311 by the mounting bolt, so as to facilitate maintenance of the mounting seat 311, the supporting member 312, the first clamping member and the second clamping member.

Both the first clamping member and the second clamping member can be fixedly disposed on the mounting seat 311, but such a structure cannot be adapted to different positions of the gas turbine 110, resulting in a poor supporting effect of the gas turbine 110. Therefore, in other embodiments, the first clamping member and the second clamping member each include a connecting rod 313 and a clamping portion 314, and the connecting rod 313 may be hinged to the mounting seat 311 by the first rotating shaft 317, so that the connecting rod 313 may rotate relative to the mounting seat 311, thereby adjusting the position of the connecting rod 313 according to different positions of the gas turbine 110, and thus better clamping the gas turbine 110. Further, the clamping portion 314 may be hinged to the connecting rod 313 by a second rotating shaft 318, so that the clamping portion 314 may be rotated to adjust a relative angle of the clamping portion 314 and the gas turbine 110, thereby better clamping the gas turbine 110. Further, a lubricating oil nipple 319 may be provided on at least one of the first and second rotating shafts 317 and 318 to alleviate wear caused by rotation.

To better accommodate different positions of the gas turbine 110, the position of the mount 311 relative to the bracket 120 may also be adjusted. Optionally, the mounting seat 311 is slidably connected to the bracket 120, the supporting assembly 310 further includes a first adjusting bolt 315, the first adjusting bolt 315 is in threaded fit with the bracket 120, and one end of the first adjusting bolt 315 abuts against a side surface of the mounting seat 311. After the first adjusting bolt 315 is screwed, the first adjusting bolt 315 can move relative to the bracket 120, so as to drive the mounting seat 311 to move, so that the mounting seat 311 can move in a plane perpendicular to the height direction of the bracket 120, thereby adjusting the position of the mounting seat 311.

Optionally, the mounting seat 311 may be slidably connected to the bracket 120, and the supporting assembly 310 further includes a second adjusting bolt 316, the second adjusting bolt 316 is in threaded fit with the mounting seat 311, and one end of the second adjusting bolt 316 abuts against a surface of the bracket 120 facing the mounting seat 311. After the second adjusting bolt 316 is screwed, the second adjusting bolt 316 can move relative to the mounting seat 311, but the position of the second adjusting bolt 316 relative to the bracket 120 cannot be changed, so that the mounting seat 311 can move in the height direction of the bracket 120 by the second adjusting bolt 316, thereby adjusting the position of the mounting seat 311.

The first and second adjusting bolts 315 and 316 may be provided in one or at least two, and when the first and second adjusting bolts 315 and 316 are provided in at least two, the position of the mount 311 may be changed in more directions, thereby better adapting to the position of the gas turbine 110.

The embodiment of the application further discloses a mobile generator set, which comprises the gas turbine 110 and the auxiliary mounting tool in any embodiment, the auxiliary mounting tool can be used for lifting the gas turbine 110 so as to adjust the position of the gas turbine 110, the centering and leveling of the gas turbine 110 are realized, and meanwhile, the auxiliary mounting tool can also be used for supporting the gas turbine 110, so that the gas turbine 110 is more reliably connected with parts such as a gear box, an engine and the like.

Referring to fig. 1 to 4 together, the present application further discloses a mounting method of a gas turbine, which can be applied to the mounting aid of any of the above embodiments, and includes:

s100, the gas turbine 110 is hoisted by a hoist line 130.

The installation aid disclosed in the embodiments of the present application includes a plurality of lifting assemblies, each of which includes a sling 130, so that one end of the plurality of slings 130 can be connected to different positions of the gas turbine 110, so that the plurality of slings 130 simultaneously apply an acting force to the gas turbine 110, thereby lifting the gas turbine 110, so as to adjust the position of the gas turbine 110.

And S200, controlling the driving mechanism to drive the sling 130 to move so that the gas turbine 110 reaches the target position.

When the driving mechanism starts to work, the driving mechanism can apply a driving force to the suspension cable 130, so as to drive the suspension cable 130 to move, and at this time, the end of the suspension cable 130 connected with the gas turbine 110 will change its position, so as to drive the gas turbine 110 to move. Since different slings 130 can produce different amplitude movements, the gas turbine 110 can be moved in different directions by means of a plurality of slings 130, thereby adjusting the position of the gas turbine 110 more flexibly and more precisely. It should be noted that the target position may be a position where the gas turbine 110 is aligned with the power take-off shaft 320.

S300, adjusting and locking the support assembly 310 to support the gas turbine 110.

After the gas turbine 110 reaches the target position, the support assembly 310 may be adjusted such that the support assembly 310 contacts the gas turbine 110 to apply a supporting force to the gas turbine 110, and then the support assembly 310 may be locked such that the position of the support assembly 310 is not changed any more to more reliably support the gas turbine 110, so that the gas turbine 110 is more reliably maintained at the target position.

After the installation method is adopted, the driving force can be output through the driving mechanism, so that the position of the gas turbine 110 is adjusted, and an operator does not need to directly apply acting force to the gas turbine 110 to change the position of the gas turbine 110, so that the installation method can reduce the manual participation degree during the installation of the gas turbine 110, thereby reducing the working intensity of the operator, simplifying the position adjustment operation of the gas turbine 110, and meanwhile, the sling 130 can be more accurately driven to move through the driving mechanism, thereby completing the position adjustment of the gas turbine 110 in a short time, shortening the installation time of the gas turbine 110, simultaneously improving the centering performance of the gas turbine 110, and preventing the gas turbine 110 from colliding with other parts.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
