Description

Technical Field

[0001] An embodiment of the present disclosure relates to a transport vehicle and an installation method for a box body of a mobile power generation system. Background Art

[0002] At present, the exhaust of on-vehicle gas turbine generator sets is mostly designed for top exhaust. The exhaust silencer needs to be transported to the site by a transport vehicle. When installing, it is necessary to connect a sling and use a crane to hoist it to the installation position for connection and installation and fixation. This method requires multiple people to cooperate. It is necessary to prepare a crane in advance. When hoisting the exhaust silencer, personnel need to climb to the installation position to command. The exhaust silencer is hoisted by a flexible steel cable and requires rope traction. After hoisting, personnel need to climb to the top of the exhaust silencer for high-altitude operation to disassemble the hoisting locks. When disassembling the exhaust silencer, personnel need to climb onto the roof of the vehicle 4 to 6 meters high, install the hoisting locks, use a crane to hoist, and remove the exhaust silencer.

[0003] There are many disadvantages in using a crane to hoist and disassemble the exhaust silencer of a top-mounted gas turbine generator set. This method requires multiple people to cooperate. It is necessary to prepare a crane in advance. When hoisting the exhaust silencer, personnel need to climb to the installation position to command. The exhaust silencer is hoisted by a flexible steel cable, which is not easy to control, difficult to install, and takes a long time to install. After hoisting, personnel need to climb to the top of the exhaust silencer for high-altitude operation to disassemble the hoisting locks, posing a safety risk to personnel. Summary of the Invention

[0046] See also Figures 1A to 4B The transport vehicle V1 of the mobile power generation system provided in the embodiment of the present disclosure includes: a chassis 100 and a lifting mechanism assembly 200 located on the chassis 100. The chassis may be, for example, an exhaust muffler or an air intake ventilation assembly for a gas turbine generator set.

[0047] The chassis 100 includes a main beam 110. For example, the main beam 110 has a bar shape extending in the straight traveling direction of the transport vehicle V1.

[0048] The main beam 110 includes a first main body portion 111 and a second main body portion 112 .

[0049] The lifting mechanism assembly 200 includes: a tilting frame 210, at least one tilting hydraulic cylinder L1, a pushing frame assembly 220, at least one lifting hydraulic cylinder L2, a connecting frame 230, and at least one pushing hydraulic cylinder L3.

[0050] The flip frame 210 is hinged to the chassis 100 at the hinge position MP of the chassis 100. The flip frame 210 includes a positioning end 211 for connecting to the chassis 100 and a free end 212 opposite to the positioning end 211.

[0051] At least one flip hydraulic cylinder L1 connects the flip frame 210 and the chassis 100 and is configured to drive the flip frame 210 to rotate relative to the chassis 100 to change the angle value of the first angle A1 between the first plane P1 where the surface of the first main body 111 facing the flip frame is located and the second plane P2 where the surface of the flip frame 210 facing away from the first main body 111 is located. In this embodiment, the two flip hydraulic cylinders L1 are arranged parallel to each other.

[0052] The connecting frame 230 is configured as a detachable connecting box. The connecting frame 230 is movably connected to the flip frame 210 in a first direction and a second direction. The first direction is a direction from the positioning end 211 of the flip frame 210 to the free end 212; the second direction is perpendicular to the second plane P2. The first direction intersects with the second direction. Here, the first direction may be, for example, parallel to the first plane P1. It is understood that the first direction changes as the flip frame 210 rotates relative to the chassis 100; the second direction also changes as the flip frame 210 rotates relative to the chassis 100.

[0053] The push frame assembly 220 is movably connected to the flip frame 210 .

[0054] At least one lifting hydraulic cylinder L2 connects the pushing frame assembly 220 and the tipping frame 210 and is configured to drive the pushing frame assembly 220 to move relative to the tipping frame 210 in a first direction. In this embodiment, the two lifting hydraulic cylinders L2 are arranged parallel to each other.

[0055] Here, moving in a certain direction includes moving forward in the certain direction and moving backward in the certain direction. Moving in a certain direction does not limit that the corresponding moving path must be parallel to the certain direction, but as long as the corresponding moving path includes a path component in the first direction.

[0056] At least one pushing hydraulic cylinder L3 connects the pushing frame assembly 220 and the connecting frame 230 and is configured to drive the connecting frame 230 to move relative to the pushing frame assembly 220 in a second direction perpendicular to the second plane P2. In this embodiment, the two pushing hydraulic cylinders L3 are arranged parallel to each other.

[0057] The first main body portion 111 is located between the hinge position MP and the second main body portion 112. The third plane P3 where the surface of the second main body portion 112 facing the tipping frame 210 is located is farther from the connecting frame 230 than the first plane P1. When the angular value of the first included angle A1 is the smallest, a part of the lifting mechanism assembly 200 is located between the first plane P1 and the third plane P3.

[0058] For example, referring to Figure 1A , the case where the angular value of the first included angle A1 between the first plane P1 where the surface of the first main body portion 111 facing the tipping frame 210 is located and the second plane P2 where the surface of the tipping frame 210 facing away from the first main body portion 111 is located is the smallest is, for example, the case where the first plane P1 where the surface of the first main body portion 111 facing the tipping frame 210 is located is parallel to the second plane P2 where the surface of the tipping frame 210 facing away from the first main body portion 111 is located.

[0059] Such as Figure 1AAs shown, when the lifting mechanism assembly 200 is in the fully retracted state, the angle value of the first included angle A1 between the first plane P1 where the surface of the first main body portion 111 faces the flipping frame 210 and the second plane P2 where the surface of the flipping frame 210 facing away from the first main body portion 111 is the smallest, and the connecting frame is closest to the pushing frame assembly 220 in the second direction. For example, when the lifting mechanism assembly 200 is in the fully retracted state, a part of each of the flipping frame 210, at least one flipping hydraulic cylinder L1, the pushing frame assembly 220, at least one lifting hydraulic cylinder L2, the connecting frame 230, and at least one pushing hydraulic cylinder L3 is located between the first plane P1 and the third plane P3. For example, when the lifting mechanism assembly 200 is in the fully retracted state, the surface of the flipping frame 210 facing away from the first main body portion 111 is the surface of the lifting mechanism assembly 200 that is farthest from the first main body portion 111 in the second direction. In this case, for example, neither the pushing frame assembly 220 nor the connecting frame 230 exceeds the second plane P2 where the surface of the flipping frame 210 facing away from the first main body portion 111 is located in the second direction.

[0060] In this way, the transport vehicle integrated with the lifting mechanism assembly provided by the embodiments of the present disclosure can realize the control and adjustment of the position of the box body in the first direction and the second direction, without the need for personnel to work at high altitudes and without additional lifting equipment, which can simplify the installation and disassembly of the box body (such as the exhaust muffler box body), shorten the installation time of the exhaust muffler, provide convenient installation, and low installation costs. In addition, since a part of the lifting mechanism assembly is located between the first plane and the third plane, the sunken space directly above the second main body portion is effectively utilized to accommodate a part of the lifting mechanism assembly, thereby avoiding an unfavorable increase in the height of the transport vehicle.

[0061] Here, the first plane P1 where the surface of the first main body portion 111 faces the flipping frame 210, the second plane P2 where the surface of the flipping frame 210 facing away from the first main body portion 111 is located, and the third plane P3 where the surface of the second main body portion 112 faces the flipping frame 210 are all virtual planes.

[0062] For example, the surface of the first main body portion 111 facing the flipping frame 210, the surface of the flipping frame 210 facing away from the first main body portion 111, and the surface of the second main body portion 112 facing the flipping frame 210 do not need to be strict planes. That is, each of the surface of the first main body portion 111 facing the flipping frame 210, the surface of the flipping frame 210 facing away from the first main body portion 111, and the surface of the second main body portion 112 facing the flipping frame 210 may have a certain degree of concave-convex structure.

[0063] For example, the surface of the second main body portion 112 facing the flipping frame 210 is parallel to the surface of the second main body portion 112 facing the flipping frame 210. Further, the surface of the second main body portion 112 facing the flipping frame 210 and the surface of the second main body portion 112 facing the flipping frame 210 are both parallel to the ground.

[0064] Continuing to refer to Figures 3 to 4B , the pushing frame assembly 220 includes: a lifting frame 221 and a sliding frame 222.

[0065] The lifting frame 221 is movably connected to the flipping frame 210. The pushing frame assembly 220 and the flipping frame 210 are connected via the lifting frame 221. At least one lifting hydraulic cylinder L2 connects the lifting frame 221 and the flipping frame 210 and is configured to drive the lifting frame 221 to move relative to the flipping frame 210 in the first direction.

[0066] For example, there are a plurality of roller bearings K1 and auxiliary bearings K2 on opposite sides of the lifting frame 221 facing the flipping frame 210. On the side wall of the flipping frame 210 facing the lifting frame 221, there is a slide rail extending in the first direction. For example, the roller bearings K1 rotate about an axis extending in the third direction; the auxiliary bearings K2 rotate about an axis extending in the second direction. The lifting frame 221 freely slides in the slide rail of the flipping frame 210 through the roller bearings K1; the auxiliary bearings K2 are used to prevent the lifting frame 221 from being stuck at a specific position of the slide rail of the flipping frame 210 due to unbalanced force when sliding in the slide rail of the flipping frame 210.

[0067] The sliding frame 222 is movably connected to the lifting frame 221. The pushing frame assembly 220 and the connecting frame 230 are connected via the sliding frame 222. At least one pushing hydraulic cylinder L3 connects the sliding frame 222 and the connecting frame 230 and is configured to drive the connecting frame 230 to move relative to the sliding frame 222 in the second direction.

[0068] The lifting mechanism assembly 200 further includes at least one sliding hydraulic cylinder. At least one sliding hydraulic cylinder L4 connects the sliding frame 222 and the lifting frame 221 and is configured to drive the sliding frame 222 to move relative to the lifting frame 221 in the third direction. The third direction is perpendicular to the intersection of the first direction and the second direction. When the transport vehicle V1 provided by the embodiments of the present disclosure is supported on a horizontal ground, the third direction can be a horizontal direction.

[0069] In this way, the transport vehicle integrated with the lifting mechanism assembly provided by the embodiments of the present disclosure can achieve the control and adjustment of the position of the box body in the first direction, the second direction, and the third direction. For example, the first direction is the up-and-down vertical direction, the second direction is the front-and-back horizontal direction, and the third direction is the left-and-right vertical direction. Therefore, the exhaust effector box body can be more accurately installed on the top of the gas turbine generator set box body.

[0070] For example, at least one sliding beam is fixedly connected to the lifting frame 221. Referring to 4A, in this embodiment, two parallel sliding beams M1 and M2 are fixedly connected to the lifting frame 221. The sliding beams M1 and M2 are, for example, welded to the lifting frame 221. Both the sliding beams M1 and M2 extend in the third direction. The sliding frame 222 is sleeved on the sliding beams M1 and M2 and can move relative to the sliding beams M1 and M2 in the third direction.

[0071] For example, the sliding frame 222 includes a first rod 2221 and a second rod 2222 that extend in the first direction, and a third rod 2223 that extends in the third direction. The first rod 2221, the second rod 2222, and the third rod 2223 are fixedly connected to each other. That is, the position of any one of the first rod 2221, the second rod 2222, and the third rod 2223 is fixed relative to the other two. For example, the third rod 2223 has a tubular shape; through holes corresponding to the sliding beams M1 and M2 are provided on each of the first rod 2221 and the second rod 2222. In this way, the third rod 2223 is sleeved on the sliding beam M2; the upper and lower ends of the first rod 2221 are respectively sleeved on the sliding beams M1 and M2; the upper and lower ends of the second rod 2222 are respectively sleeved on the sliding beams M1 and M2.

[0072] For example, the sliding frame 222 is movably connected to the connecting frame 230 through at least one articulated arm N. The at least one articulated arm N is hinged to the connecting frame 230 through a first rotating shaft S1. The at least one lifting hydraulic cylinder L3 is hinged to the connecting frame 230 through a second rotating shaft S2. Both the first rotating shaft S1 and the second rotating shaft S2 extend in the third direction and are coaxially arranged. Here, the coaxial arrangement of the first rotating shaft S1 and the second rotating shaft S2 is not limited to the case where the axis of the first rotating shaft S1 coincides exactly with the axis of the second rotating shaft S2, and a certain deviation is allowed. For example, in the third direction, the first rotating shaft S1 overlaps with the second rotating shaft S2. That is, a straight line extending in the third direction can pass through the first rotating shaft S1 and the second rotating shaft S2. In this way, it is beneficial for the torque provided by the at least one lifting hydraulic cylinder L3 to be efficiently transmitted to the at least one articulated arm N, so as to more efficiently push out the connecting frame 230. It can be understood that in other embodiments, the first rotating shaft S1 and the second rotating shaft S2 may be non-coaxially arranged. For example, in the third direction, the first rotating shaft S1 does not overlap with the second rotating shaft S2. That is, a straight line extending in the third direction can only pass through one of the first rotating shaft S1 and the second rotating shaft S2.

[0073] For example, the at least one sliding hydraulic cylinder includes a first sliding hydraulic cylinder L4-1 and a second sliding hydraulic cylinder L4-2. In the first direction, the at least one lifting hydraulic cylinder L3 is located between the first sliding hydraulic cylinder L4-1 and the second sliding hydraulic cylinder L4-2.

[0074] For example, in the first direction, the first sliding hydraulic cylinder L4-1 is located between the sliding frame 222 and the lifting frame 211; in the second direction, the second sliding hydraulic cylinder L4-2 is located between the sliding frame 222 and the connecting frame 230, for example.

[0075] For example, a mounting support 2225 is fixedly connected to the sliding frame 222. Refer to Figure 4A , the mounting support 2225 is fixedly connected to the first rods 2221 and 2222 of the sliding frame 222 through a rod-shaped member 2224 extending in the third direction. In the second direction, the end of the support of the mounting support 2225 is closer to the second main body portion 112 of the chassis than the sliding frame 222. For example, the mounting support 2225 adopts a cantilever structure.

[0076] For example, opposite ends of the first sliding hydraulic cylinder L4-1 are respectively connected to the third rod 2223 of the sliding frame 222 and the lifting frame 211; opposite ends of the second sliding hydraulic cylinder L4-2 are respectively connected to the sliding beam M1 and the rod-shaped member 2224.

[0077] At least one lifting hydraulic cylinder L3 has opposite third end L3-1 and fourth end L3-2. The third end L3-1 and the fourth end L3-2 are movable relative to each other. The third end L3-1 is hinged to the support end of the mounting support 2225 of the lifting frame assembly 220, and the fourth end L3-2 is hinged to the connecting frame 230.

[0078] The at least one lifting hydraulic cylinder L3 is closer to the second main body 112 of the chassis than the sliding frame 222 in the second direction. In this way, the installation space of the at least one lifting hydraulic cylinder L3 can be increased. When the lifting mechanism assembly is in a fully retracted state, the support end of the mounting support 2225 and the end of the at least one lifting hydraulic cylinder L3 hinged to the support end are located between the first plane P1 and the third plane P3.

[0079] Figure 5A A schematic diagram showing the front structural view of a connection frame of a transport vehicle for a box body of a mobile power generation system provided by an embodiment of the present disclosure; Figure 5B A side structural schematic diagram showing a connection frame of a transport vehicle for a box body of a mobile power generation system provided in an embodiment of the present disclosure.

[0080] See also Figure 1B , Figure 5A and 5B The connecting frame 230 has at least one connecting end T on the side away from the hinge position MP. In the present embodiment, the number of the at least one connecting end T is, for example, two. Each connecting end T has a trapezoidal shape. Here, the trapezoidal shape refers to a shape having four substantially trapezoidal side surfaces. Here, substantially trapezoidal means that it is not a strict trapezoid, and a certain degree of deformation is allowed. For example, a socket with a trapezoidal shape corresponding to at least one connecting end T may be provided on the exhaust muffler housing. In this way, the connection and removal of the connecting frame 230 and the exhaust muffler housing can be facilitated.

[0081] Return to see Figures 1A to 2 , a portion of at least one flip hydraulic cylinder L1 is located on the side of the third plane P3 opposite to the first plane P1. In this way, the installation space of at least one flip hydraulic cylinder L1 is effectively increased and the initial lifting angle can be increased. Therefore, a hydraulic cylinder with a larger initial length (minimum length in a compressed state) can be used as a flip hydraulic cylinder to provide a greater flip thrust to the flip frame 210. For example, the flip hydraulic cylinder L1 is a double-acting three-stage cylinder. In this way, the transport vehicle V1 provided in the embodiment of the present disclosure can realize the lifting and installation of a 6-ton exhaust muffler box.

[0082] For example, the chassis 100 further includes a box girder 113 fixedly connected to the second main body portion 112 of the main girder 110. The box girder 113 is disposed intersecting the second main body portion 112. At least one tipping hydraulic cylinder L1 and the chassis 100 are connected via the box girder 113. In this way, the strength of the chassis 100 can be increased, so that the lifting of the heavy exhaust effector box can be achieved. Specifically, the box girder 113 protrudes from the second main body portion 112 on both opposite sides of the second main body portion 112. Here, the cross-sectional shape of the box girder 113 is similar to the cross-sectional shape of an ordinary box body.

[0083] For example, at least one tipping hydraulic cylinder L1 has opposite first end L1-1 and second end L1-2. The first end L1-1 and the second end L1-2 are movable relative to each other. The first end L1-1 is hinged to the tipping frame 210, and the second end L1-2 is hinged to the side surface of the box girder 113 of the chassis 100 facing the first main body portion 111.

[0084] For example, the transport vehicle V1 provided according to an embodiment of the present disclosure further includes a limit frame 300. The limit frame 300 includes a first sub-limit frame 310 and a second sub-limit frame 320 hinged to each other. The first sub-limit frame 310 is hinged to the tipping frame 210, and the second sub-limit frame 320 is hinged to the first main body portion 111 of the chassis 100.

[0085] The limit frame 300 can limit the tipping angle of the tipping frame 210 (i.e., the first included angle A1 between the first plane and the second plane). For example, under the limitation of the limit frame 300, the maximum tipping angle of the tipping frame 210 does not exceed 92°.

[0086] The limit frame 300 is made by welding profiles. Compared with a flexible rope limit member, the movement track of the limit frame 300 is controllable, so that entanglement interference with the chassis 100 can be avoided; and the limit frame 300 can also be used as a bracket for other components (such as hydraulic pipelines and electrical lines).

[0087] For example, in the case where the first included angle is the largest, the second included angle between the surface of the second sub-limit frame 320 facing the first main body portion 111 and the surface of the first main body portion 111 facing the second sub-limit frame 320 is greater than or equal to 45°. In this way, the limiting effect of the limit frame 300 on the tipping frame 210 can be better ensured when the first included angle is the largest.

[0088] For example, the transport vehicle V1 provided according to an embodiment of the present disclosure further includes a hydraulic pipeline D disposed on the limit frame 300. The hydraulic pipeline D is, for example, a hydraulic hard pipe.

[0089] The first end L1-1 of the tilting hydraulic cylinder L1 has a relatively large range of motion as it follows the rotation of the tilting frame 210, while the second end L1-2 of the tilting hydraulic cylinder L1 is relatively fixed in position as it is hinged to the chassis 100. For example, all the openings of at least one tilting hydraulic cylinder L1 for communicating with the external liquid are only located at the second end L1-2. For example, all the openings of at least one tilting hydraulic cylinder L1 for communicating with the external liquid are connected to the hydraulic pipeline D through hydraulic hoses. In this way, it is possible to avoid the hydraulic pipeline connected to at least one tilting hydraulic cylinder L1 from moving along with the tilting frame 210, thereby avoiding adverse interference of the hydraulic pipeline on the movement of the lifting mechanism assembly.

[0090] The fourth end L3-2 of the lifting hydraulic cylinder L3 has a relatively large range of motion as it follows the movement of the connecting frame 230, while the third end L3-1 of the lifting hydraulic cylinder L3 is relatively fixed in position as it is hinged to the lifting frame assembly 220. For example, all the openings of at least one lifting hydraulic cylinder L3 for communicating with the external liquid are only located at the third end L3-1. For example, all the openings of at least one lifting hydraulic cylinder L3 for communicating with the external liquid are connected to the hydraulic pipeline D through hydraulic hoses. In this way, it is possible to avoid the hydraulic pipeline connected to at least one lifting hydraulic cylinder L3 from moving along with the connecting frame 230, thereby avoiding adverse interference of the hydraulic pipeline on the movement of the lifting mechanism assembly.

[0091] Continue to refer to Figure 1A and Figure 1B , the transporter V1 of the box body of the mobile power generation system provided by the embodiment of the present disclosure further includes a tilting frame attitude control system 104 provided on the sliding frame 221, and a hydraulic power unit 101, an electric control system 102, a hydraulic control system 103, a transporter attitude control system 105, a laser rangefinder 106, and hydraulic outriggers 107 provided on the chassis 100. For example, the exhaust muffler transporter is in the form of a trailer.

[0092] The hydraulic system of the transport vehicle V1 for the box body of the mobile power generation system provided by the embodiments of the present disclosure mainly consists of a hydraulic power unit 101 and a hydraulic control system 103. The hydraulic power unit 101 is composed of a hydraulic oil tank, a hydraulic pump, a hydraulic pump drive motor, a bell housing connecting the hydraulic pump and the hydraulic drive motor, a coupling, etc., and provides the required power for the lifting mechanism. The hydraulic control system 103 is composed of a multi-way electromagnetic control valve, a balance valve, a pressure gauge and a pressure display, etc. The manual control lever of the multi-way electromagnetic control valve can be used to manually control the tilting hydraulic cylinder L1, the lifting hydraulic cylinder L2, the pushing hydraulic cylinder L3 and the sliding hydraulic cylinder L4. At the same time, the multi-way electromagnetic control valve can receive the control signal provided by the electrical control system to realize the remote control of the tilting hydraulic cylinder L1, the lifting hydraulic cylinder L2, the pushing hydraulic cylinder L3 and the sliding hydraulic cylinder L4 by the electrical system. The balance valve can synchronize the tilting hydraulic cylinder L1, the lifting hydraulic cylinder L2, the pushing hydraulic cylinder L3 and the sliding hydraulic cylinder L4 to make the system control more stable. The pressure gauge and the pressure display can display the pressure of the hydraulic system, which is convenient for the operator to make decisions and judgments.

[0093] The electrical system of the transport vehicle V1 for the box body of the mobile power generation system provided by the embodiments of the present disclosure mainly consists of an electrical control system 102, a transport vehicle attitude control system 105, a laser rangefinder 106, and a tilting frame attitude control system 104. The electrical control system 102 can provide power for the hydraulic drive motor and control the start and stop of the hydraulic drive motor. The electrical control system 102 is equipped with a controller, a wireless remote control transceiver and a wireless remote control. The operator can send a control signal to the wireless remote control transceiver through the wireless remote control. After receiving the control signal, the wireless remote control transceiver sends a control signal to the multi-way electromagnetic control valve through the controller to control the tilting hydraulic cylinder L1, the lifting hydraulic cylinder L2, the pushing hydraulic cylinder L3 and the sliding hydraulic cylinder L4, so as to realize the remote control of the lifting mechanism assembly. The transport vehicle attitude control system 105 and the laser rangefinder 106 can adjust the relative positions of the exhaust muffler transport vehicle and the gas turbine generator set transport vehicle, and at the same time send the attitude information of the exhaust muffler transport vehicle to the controller and display it on the display screen of the controller. At the same time, this data information can be remotely transmitted to the display screen of the wireless controller, which is convenient for the operator to make decisions and judgments. The tilting frame attitude control system 104 can measure the tilting angle of the tilting frame and send the detected data information to the controller and display it on the display screen of the controller. At the same time, this data information can be remotely transmitted to the display screen of the wireless controller, which is convenient for the operator to make better operation decisions and judgments.

[0094] Figure 6 The flowchart showing the installation method of the box body of the mobile power generation system provided by another embodiment of the present disclosure is shown.

[0095] See Figure 6 , the installation method of the box body of the mobile power generation system provided by another embodiment of the present disclosure includes:

[0096] A connecting frame 230 that connects the box body C1 to the transport vehicle V1 provided in the above embodiment;

[0097] When driving the flipping frame 210 to rotate so that the first included angle A1 has a first angular value, driving the connecting frame 230 to move away from the flipping frame 210 in a second direction so that the flipping frame 210 and the connecting frame 230 are spaced apart in the second direction, wherein the first angular value is an acute angular value; and

[0098] When driving the flipping frame 210 to rotate so that the first included angle A1 has a second angular value, driving the pushing frame assembly 220 to move in a first direction, wherein the second angular value is greater than the first angular value.

[0099] Compared with pushing out the box body when the first included angle is zero or 90°, when the first included angle is acute, firstly, the force on the flipping hydraulic cylinder in the initial state can be reduced, and at the same time, it can be avoided that the box body C1 on the flipping frame continues to flip and causes adverse interference with the box body on the gas turbine transport vehicle.

[0100] For example, the first angular value is greater than or equal to 20° and less than or equal to 60°. This can be more beneficial to improving the overall force state of the flipping hydraulic cylinder.

[0102] Next, refer to Figures 7A to 7E Specifically describe the installation method of the box body of the mobile power generation system provided by another embodiment of the present disclosure.

[0103] As Figure 7A shown, the exhaust silencer transport vehicle V1 transports the exhaust silencer box body C1 containing the exhaust silencer to a designated position. At Figure 7AIn the shown transportation state, the connection frame 230 of the exhaust muffler transport vehicle V1 is connected to the exhaust muffler box body C1. For example, the distance between the exhaust muffler transport vehicle V1 and the gas turbine generator set transport vehicle V2 is measured by the laser rangefinder 106, and this distance is adjusted to an appropriate range. Then, the exhaust muffler transport vehicle V1 is supported by the hydraulic outriggers 107, and the exhaust muffler transport vehicle V1 is adjusted to a horizontal state through the transport vehicle attitude control system 105, completing the relative position adjustment of the exhaust muffler transport vehicle V1 and the gas turbine generator set transport vehicle V2.

[0104] As Figure 7B shown, the tilting frame 210 is driven by the tilting hydraulic cylinder L1 to rotate to the first angle value. That is, the tilting frame 210 is driven by the tilting hydraulic cylinder L1 to rotate so that the first included angle A1 has the first angle value. For example, this first angle value is 30°.

[0105] As Figure 7C shown, when the first included angle A1 has the first angle value, the exhaust muffler box body C1 connected to the connection frame 230 is pushed away from the tilting frame 210 by the pushing hydraulic cylinder L3.

[0106] As Figure 7D shown, the tilting frame 210 is continuously driven by the tilting hydraulic cylinder L1 to rotate to the second angle value. That is, the tilting frame 210 is driven by the tilting hydraulic cylinder L1 to rotate so that the first included angle A1 has the second angle value. For example, this first angle value is 90°. The limit frame 300 and the tilting frame attitude control system 104 can limit the tilting degree of the tilting frame 210 to prevent imbalance caused by excessive tilting degree.

[0107] As Figure 7D shown in the state, the position of the exhaust muffler box body C1 in the length direction of the gas turbine generator set transport vehicle V2 can be adjusted by the sliding hydraulic cylinder L4; the position of the exhaust muffler box body C1 in the width direction of the exhaust muffler box body C1 can be adjusted by the pushing hydraulic cylinder L2; the position of the exhaust muffler box body C1 in the height direction (i.e., the vertical direction) of the gas turbine generator set transport vehicle V2 can be adjusted by the lifting hydraulic cylinder L2.

[0108] Refer to Figure 7E , after the position adjustment of the exhaust muffler box body C1 is completed, the exhaust muffler box body C1 is lowered onto the top of the gas turbine generator set box body C2 equipped with the gas turbine generator set of the gas turbine generator set transport vehicle V2 by the lifting hydraulic cylinder L2. For example, the exhaust muffler box body C1 is fixed by the automatic locking mechanism of the gas turbine generator set transport vehicle V2, completing the installation of the exhaust muffler box body C1.

[0109] Then, by continuously lowering the lifting hydraulic cylinder L2, the connecting frame 230 can be separated from the exhaust muffler housing C1. Then, the tilting frame 210 can be driven by the tilting hydraulic cylinder L1 to rotate to an acute angle (i.e., the first included angle has an acute angle value), and in this state, the connecting frame can be retracted by the lifting hydraulic cylinder. Next, the tilting frame 210 is continuously driven by the tilting hydraulic cylinder L1 to rotate until the tilting frame 210 is rotated to the transportation state by continuously driving the tilting hydraulic cylinder. For example, in this transportation state, the lifting mechanism assembly is in a fully retracted state, and the angle value of the first included angle is, for example, zero. In this way, the exhaust muffler transport vehicle V1 can drive away from the gas turbine generator set transport vehicle V2, reducing the occupation of the site.
