[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0041] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] refer to Figures 1 to 16 This embodiment of the present application discloses a transport vehicle for transporting equipment 700. The equipment 700 may be a top-mounted exhaust muffler for a gas turbine power generation project. Alternatively, it may be other equipment, which is not specifically limited in this embodiment of the present application. The disclosed transport vehicle includes a chassis trailer 100, a lifting device 200, and a suspension device 300.

[0043] The chassis trailer 100 is a basic component of the transport vehicle. It can provide an installation base for the lifting device 200, the suspension device 300, etc. In addition, the chassis trailer 100 can also be used to carry the equipment body 700 to achieve transportation of the equipment body 700. In some embodiments, the chassis trailer 100 can have a load-bearing area 111 and a suspension area 112. The load-bearing area 111 is used to carry the equipment body 700 during transportation to ensure the stability and firmness of the equipment body 700. After the transport vehicle transports the equipment body 700 to the destination, the lifting device 200 can be used to lift and flip the equipment body 700, so that the equipment body 700 is transferred to the suspension area 112, so that the equipment body 700 can be suspended and transferred by the suspension device 300. In a more specific embodiment, the load-bearing area 111 and the suspension area 112 are arranged adjacent to each other to facilitate the movement of the equipment body 700 from the load-bearing area 111 to the suspension area 112.

[0044] The lifting device 200 is used to lift and flip the device body 700 to change the position and shape of the device body 700, thereby facilitating the transfer of the device body 700 to a designated location. In some embodiments, the lifting device 200 may include a lifting drive mechanism 210 and a frame 220, wherein the lifting drive mechanism 210 is used to provide a driving force for lifting and flipping, and the frame 220 is used to carry the device body 700. Specifically, the lifting drive mechanism 210 connects the frame 220 to the chassis trailer 100, and the frame 220 is flipably connected to the chassis trailer 100. In this way, under the driving action of the lifting drive mechanism 210, the frame 220 can flip relative to the chassis trailer 100, so that the device body 700 can be driven by the frame 220 to move to achieve lifting and flipping.

[0045] Optionally, one end of the frame 220 can be mounted to the chassis trailer 100 via a rotating shaft, so that the frame 220 can rotate around the rotating shaft under the driving action of the lifting drive mechanism 210 to achieve lifting and flipping of the device body 700. In addition, the lifting drive mechanism 210 can be a linear drive mechanism.

[0046] Because the frame 220 is reversible relative to the chassis trailer 100, it can have a first state and a second state relative to the chassis trailer 100, wherein the first state is a load-bearing state and the second state is a reversible state. Thus, in the first state, the frame 220 is laid flat on the load-bearing area 111. At this time, the device body 700 is placed on the frame 220, and the frame 220 supports the device body 700, thereby ensuring the stability of the device body 700 during transportation. In the second state, the frame 220 is upright on the chassis trailer 100, and the device body 700 is upright on the suspension area 112.

[0047] The specific process from the first state to the second state is as follows: in the initial state (i.e., before the equipment body 700 is transported to the destination), the frame 220 is laid flat on the load-bearing area 111 (for example, it can be in a horizontal state), and the upper part of the frame 220 carries the equipment body 700; when arriving at the destination, in order to facilitate suspension, it is first necessary to change the state of the equipment body 700. At this time, the lifting drive mechanism 210 is started. Under the driving action of the lifting drive mechanism 210, the frame 220 is flipped from the flat state to the upright state (for example, it can be in a vertical state). During this process, the equipment body 700 is flipped together with the frame 220, so that it can be gradually lifted from the load-bearing area 111. Finally, the flipped equipment body 700 stands upright in the suspension area 112, which can facilitate the subsequent suspension of the equipment body 700 by the suspension device 300 to improve the transfer efficiency of the equipment body 700.

[0048] The suspension device 300 is provided on the chassis trailer 100 and is used to suspend the equipment body 700 from the suspension area 112 and transport it to a predetermined location. For example, the suspension device 300 can be connected to one end of the chassis trailer 100, specifically the front or rear end of the chassis trailer 100, to provide sufficient space for supporting the equipment body 700.

[0049] In the embodiment of the present application, the lifting device 200, the suspension device 300 and the chassis trailer 100 are effectively combined to achieve an integrated effect, so that there is no need to prepare a separate crane, but the equipment body 700 can be lifted by the suspension device 300 provided on the chassis trailer 100; in addition, the equipment body 700 can be flipped and moved by the lifting device 200 to facilitate the suspension device 300 to suspend the equipment body 700; the equipment body 700 can be suspended and transferred to a preset position by the suspension device 300, and in this process, there is no need to use a sling, and there is no need for personnel to work at high altitude to install or remove the sling, and there is no need for personnel to direct the operation at high altitude, which can reduce the difficulty of the operation, improve the convenience of operation, and avoid personnel safety risks.

[0050] In order to make the movement of the suspension device 300 more flexible, the suspension device 300 in the embodiment of the present application can be a folding arm crane, which can make the suspension process more flexible so as to improve adaptability.

[0051] refer to Figure 2 In some embodiments, the suspension device 300 may include a mechanical arm 310 and a gripper 320, wherein one end of the mechanical arm 310 is rotatably connected to the chassis trailer 100, and the gripper 320 is connected to the other end of the mechanical arm 310 for grasping or releasing the device body 700. For example, the mechanical arm 310 may be a multi-axis mechanical arm 310, which may include multiple small arms, wherein adjacent small arms may rotate relative to each other, and the rotation axes may be parallel or non-parallel. Thus, different swing forms can be achieved, thereby expanding the reach of the suspension device 300.

[0052] The gripper 320 can be a hydraulic clamp, which drives the gripper 320 hydraulically to perform a gripping action or a releasing action. In this way, when gripping the device body 700, it can ensure that the device body 700 is not easy to fall off, and when releasing the device body 700, it can be quickly released.

[0053] Based on the above settings, there is no need to set ropes on the device body 700, and there is no need for personnel to install or remove the ropes, thereby reducing the labor intensity and safety risks of personnel, and improving the suspension or release efficiency of the device body 700, so as to improve the installation or disassembly efficiency of the device body 700.

[0054] refer to Figure 2 and Figure 15 In order to improve the placement accuracy of the equipment body 700, the transport vehicle in the embodiment of the present application may further include a first imaging element 410 and a first laser emitting element 420, wherein the first laser emitting element 420 is used to emit a laser marking line, and the first imaging element 410 is used to shoot the laser marking line. The first imaging element 410 and the first laser emitting element 420 are both arranged on the gripper 320, and the first imaging element 410 and the first laser emitting element 420 are both electrically connected to the control device 500 of the transport vehicle.

[0055] Specifically, when the device body 700 is moved to the preset position, the suspension device 300 first moves the device body 700 to a position above the preset position. The control device 500 then controls the suspension device 300 to stop moving and controls the first laser emitting element 420 to emit a laser marking line toward the preset position. The first imaging element 410 is used to observe and photograph whether the laser marking line is within the target area of ​​the preset position, thereby determining whether the device body 700 is placed at the preset position. When the laser marking line is within the target area, it indicates that the position of the device body 700 is relatively accurate, and the device can be placed directly downward to ensure positioning accuracy. When the laser marking line extends beyond the target area, it indicates that there is a deviation in the position of the device body 700. At this time, the control device 500 controls the suspension device 300 to make adaptive adjustments to ensure that the laser marking line is within the target area.

[0056] Optionally, the first laser emitting element 420 can emit a cross laser marking line, and accordingly, the target area at the preset position can be a cross target area. This method can be used to position in two directions perpendicular to each other in the horizontal plane, thereby improving positioning accuracy to ensure the position accuracy of the device body 700. In addition, the first imaging element 410 can be a camera, etc.

[0057] In some embodiments, both the robotic arm 310 and the gripper 320 can be hydraulically driven to improve the suspension capability of the robotic arm 310 and the gripper 320, thereby improving the suspension capability of the entire suspension device 300 to a certain extent. To this end, the transport vehicle can include a hydraulic system 600. The hydraulic system 600 can include oil circuits connected to the robotic arm 310 and the gripper 320, respectively, to transmit hydraulic oil to the robotic arm 310 and the gripper 320 through the oil circuits and to achieve hydraulic oil return, thereby providing power to the robotic arm 310 and the gripper 320. In addition, the hydraulic system 600 can also include a hydraulic power unit (e.g., a hydraulic pump, etc.) and hydraulic control components (e.g., various control valves, etc.).

[0058] To determine whether the gripper 320 has completely released the device body 700, in some embodiments, the oil circuit connected to the robotic arm 310 and / or the oil circuit connected to the gripper 320 is provided with a pressure detection element 460, which is electrically connected to the control device 500 of the transport vehicle. Based on this, the pressure detection element 460 can detect the oil pressure in the oil circuit. When the device body 700 is not released, the robotic arm 310 and the gripper 320 are both loaded, and the oil pressure in the oil circuit connected to the robotic arm 310 and the oil circuit connected to the gripper 320 is relatively high. Conversely, when the device body 700 is released, the robotic arm 310 and the gripper 320 are both unloaded (gravity is negligible), and the oil pressure in the oil circuit connected to the robotic arm 310 and the oil circuit connected to the gripper 320 is relatively low. Based on the above situation, the oil pressure of at least one of the oil circuit connected to the robotic arm 310 and the oil circuit connected to the gripper 320 can be detected by the pressure detection element 460, and the detected oil pressure result can be sent to the control device 500. The control device 500 compares the detected oil pressure data with the preset oil pressure data to determine whether the equipment body 700 is released.

[0059] By judging whether the equipment body 700 is released, the suspension device 300 can be effectively prevented from being affected by the equipment body 700 when returning to its position. In this way, on the one hand, the normal return of the suspension device 300 can be guaranteed to prepare for the next suspension. On the other hand, it can also prevent the suspension device 300 from bringing down the equipment body 700 and causing damage to the equipment body 700.

[0060] Optionally, the pressure detection element 460 may be a pressure sensor. Of course, it may also be other types, which is not specifically limited in the embodiment of the present application.

[0061] refer to Figure 3 and Figure 4 To improve the stability of the lifting process, the lifting drive mechanism 210 may include a first lifting cylinder 211 and a second lifting cylinder 212, wherein one end of the first lifting cylinder 211 is movably connected to one side of the chassis trailer 100 in the left-right direction, and the other end of the first lifting cylinder 211 is movably connected to the frame 220. Similarly, one end of the second lifting cylinder 212 is movably connected to the other side of the chassis trailer 100 in the left-right direction, and the other end of the second lifting cylinder 212 is movably connected to the frame 220, wherein the left-right direction is perpendicular to the direction of travel of the transport vehicle. For example, one end of the first lifting cylinder 211 may be rotatably connected to one side of the chassis trailer 100 via a rotating shaft, and the other end may be connected to the frame 220 via a rotating shaft. The second lifting cylinder 212 may be connected to the other side of the chassis trailer 100 via a rotating shaft, and the other end may be connected to the frame 220 via a rotating shaft.

[0062] Based on the above settings, the first lifting cylinder 211 and the second lifting cylinder 212 can apply driving force to the frame 220 from the left and right sides respectively, so that the left and right sides of the frame 220 are subjected to more balanced force, thereby effectively preventing the frame 220 from deforming due to uneven force on both sides, thereby ensuring the stability of the frame 220, further improving the lifting stability of the equipment body 700, and effectively preventing the equipment body 700 from tipping over and being damaged during the lifting process.

[0063] In addition, the connection points between the first lifting cylinder 211 and the second lifting cylinder 212 and the frame 220 are both far away from the rotational connection point between the frame 220 and the chassis trailer 100, so that the driving torque can be increased under the same driving force. That is, when achieving the same driving torque, smaller-sized first lifting cylinders 211 and second lifting cylinders 212 can be selected, thereby reducing costs.

[0064] refer to Figure 15 In some embodiments, the transport vehicle may further include a distance measuring element 430 disposed on a side of the chassis trailer 100 and electrically connected to the transport vehicle's control device 500 for detecting the left-right distance between the chassis trailer 100 and a preset location. For example, multiple distance measuring elements 430 may be disposed on the left and / or right sides of the chassis trailer 100, and the multiple distance measuring elements 430 may be spaced apart along the front-to-back direction of the chassis trailer 100. This allows the multiple distance measuring elements 430 to respectively detect the left-to-right distance between the chassis trailer 100 and the preset location, wherein the front-to-back direction is parallel to the direction of travel of the transport vehicle.

[0065] In some cases, the device body 700 can be placed on the top surface of the power generation vehicle 800, and a certain area on the top surface of the power generation vehicle 800 is the preset position. At this time, before moving the device body 700 to the preset position, the chassis trailer 100 can be placed parallel to the power generation vehicle 800, that is, the front and rear directions of the chassis trailer 100 are parallel to the front and rear directions of the power generation vehicle 800. At this time, multiple distance measuring elements 430 can measure the distance of multiple areas between the chassis trailer 100 and the power generation vehicle 800 to facilitate adjusting the distance between the chassis trailer 100 and the power generation vehicle 800 so that the distance between the chassis trailer 100 and the power generation vehicle 800 is within the preset range embedded in the control device 500, such as within the range of 2.3 meters to 3 meters.

[0066] Based on the above settings, the distances between multiple areas between the chassis trailer 100 and the power generation vehicle 800 can be detected by multiple distance measuring elements 430, and the distance information can be sent to the control device 500. The control device 500 compares the distance information detected by the multiple distance detection elements with the preset range to determine whether it is within the preset range. When the multiple distance information detected are all within the preset range, it indicates that the relative position between the chassis trailer 100 and the power generation vehicle 800 meets the requirements, so that the next step can be performed to hoist the equipment body 700 to the top of the power generation vehicle 800; when at least part of the multiple distance information detected is not within the preset range, it indicates that the relative position between the chassis trailer 100 and the power generation vehicle 800 does not meet the requirements. At this time, the position of the chassis trailer 100 can be controlled and adjusted to adjust until the suspension requirements are met.

[0067] Optionally, the distance measuring element 430 may be a laser rangefinder to improve the distance measurement accuracy.

[0068] Continue to refer Figure 15 In order to determine the position accuracy of the transport vehicle in the front-to-back direction, the transport vehicle may further include a second imaging element 440 and a second laser emitting element 450, wherein the second imaging element 440 and the second laser emitting element 450 are both arranged on the side of the chassis trailer 100, the second imaging element 440 is used to emit a laser marking line, the second imaging element 440 is used to photograph the laser marking line, and the second laser emitting element 450 and the second imaging element 440 are both electrically connected to the control device 500 of the transport vehicle, and the control device 500 can determine the distance between the chassis trailer 100 and the preset position in the front-to-back direction based on the laser marking line photographed by the second imaging element 440.

[0069] Specifically, as the transport vehicle approaches a preset position, the second imaging element 440 is controlled to emit a laser marking line toward the preset position. The second imaging element 440 then observes and photographs the laser marking line to determine whether it is within the target area at the preset position, thereby determining whether the transport vehicle has reached the designated position. If the laser marking line is within the target area, the transport vehicle's position is relatively accurate, and the suspension operation can be performed. If the laser marking line is outside the target area, it indicates that the transport vehicle's position is deviated. In this case, the control device 500 controls the chassis trailer 100 to make adaptive adjustments to ensure that the laser marking line is within the target area.

[0070] Optionally, the second laser emitting element 450 can emit a cross laser marking line, and accordingly, the target area at the preset position can be a cross target area. This method can be used to position in two directions perpendicular to each other in the horizontal plane, thereby improving positioning accuracy to ensure the position accuracy of the device body 700. In addition, the second imaging element 440 can be a camera, etc.

[0071] Based on the above arrangement, the distance between the transport vehicle and the device body 700 it carries and the preset position in the front-to-back direction can be adjusted, thereby achieving adjustment of the front-to-back distance.

[0072] In some cases, the device body 700 can be placed on the top surface of the power generation vehicle 800, and a certain area on the top surface of the power generation vehicle 800 is the preset position. At this time, before moving the device body 700 to the preset position, the distance between the chassis trailer 100 and the power generation vehicle 800 in the front and rear directions can be adjusted first. At this time, the second laser emitting element 450 and the second camera element 440 cooperate with each other to realize the acquisition of the position of the chassis trailer 100, so as to adjust the front and rear distance between the chassis trailer 100 and the power generation vehicle 800, so that the front and rear distance between the chassis trailer 100 and the power generation vehicle 800 is within the preset range embedded in the control device 500.

[0073] refer to Figure 2 To improve the stability of the entire transport vehicle during lifting and suspension, the chassis trailer 100 may further include a trailer body 110 and a plurality of retractable support legs 120. The plurality of support legs 120 are respectively disposed at the edges of the trailer body 110. In some embodiments, the retraction and extension of the plurality of support legs 120 may be hydraulically driven to increase the supporting force of the support legs 120, thereby improving the stability of the chassis trailer 100 to a certain extent. Based on this, the transport vehicle may further include a hydraulic system 600. The hydraulic system 600 may include an oil circuit. The plurality of support legs 120 are connected to the oil circuit of the transport vehicle's hydraulic system 600. The oil circuit transmits hydraulic oil to each support leg 120 and realizes the return of the hydraulic oil, thereby providing power to each support leg 120.

[0074] In order to further improve the stability of the entire transport vehicle during the lifting and suspension process, the transport vehicle may also include a leveling device, wherein the leveling device may include an inclination detection element 470 arranged on the trailer body 110, and the inclination detection element 470 and the hydraulic system 600 are both connected to the control device 500 of the transport vehicle. The control device 500 is used to control the corresponding extension and retraction of at least part of the support legs 120 through the hydraulic system 600 according to the inclination information of the trailer body 110 detected by the inclination detection element 470, so as to level the trailer body 110.

[0075] Specifically, before the suspension equipment body 700, multiple support legs 120 are extended respectively to support the trailer body 110. At the same time, the inclination detection element 470 detects the inclination of the trailer body 110. When the detected inclination is within the preset inclination range embedded in the control device 500, it is determined that the trailer body 110 meets the suspension requirements and does not need to be leveled; when at least part of the detected inclination is not within the preset inclination range embedded in the control device 500, it is determined that the trailer body 110 is tilted too much and needs to be leveled. At this time, the control device 500 controls the corresponding support legs 120 to extend and retract through the hydraulic system 600, so as to facilitate the corresponding lifting and lowering of the part of the trailer body 110, thereby realizing the leveling of the trailer body 110, and then meeting the suspension requirements to ensure that the transport vehicle will not tilt or roll over during the suspension process, and the stability of the transport vehicle can be guaranteed.

[0076] Optionally, the tilt detection element 470 may be an inclinometer or the like.

[0077] Considering that in some cases the height of the equipment body 700 is too large to meet actual requirements and affects the layout space of the lifting device 200, a part of the chassis trailer 100 can be set as a sinking area to increase the lifting space of the equipment body 700 through the sinking area.

[0078] refer to Figure 4 In some embodiments, the bearing area 111 has a first bearing surface 1111, the suspension area 112 has a second bearing surface 1121, the horizontal position of the first bearing surface 1111 is lower than the horizontal position of the second bearing surface 1121, and the first bearing surface 1111 and the second bearing surface 1121 are connected by an inclined surface 1131. Based on this, the load-bearing area 111 is a sinking area. Before the lifting device 200 is lifted, the frame 220 is located in the load-bearing area 111, and the equipment body 700 is located on the frame 220. Since the load-bearing area 111 is lower, the equipment body 700 is also relatively low. Correspondingly, the suspension area 112 is higher. In this way, the lifting device 200 can lift and flip the equipment body 700 located in a low-lying area to the suspension area 112 at a high position, thereby increasing the lifting space, so that the equipment body 700 can be lifted and flipped on the chassis trailer 100, thereby facilitating the movement of the equipment body 700 from the load-bearing area 111 to the suspension area 112, and the layout space of the lifting cylinder in the lifting device 200 can be increased.

[0079] Optionally, the load-bearing area 111 of the chassis trailer 100 may adopt a box beam structure to increase the strength of the chassis trailer 100 .

[0080] refer to Figure 3In some embodiments, the transport vehicle may further include a fence 130, which is disposed on the chassis trailer 100 and encloses a storage space on the chassis trailer 100. For example, components such as the control device 500 and the hydraulic system 600 may be disposed within the storage space. The fence 130 protects the components contained within the storage space, preventing external factors from interfering with or damaging the components.

[0081] In a more specific embodiment, the fence 130 may be disposed at the end of the chassis trailer 100 away from the suspension device 300 . Of course, the fence 130 may also be disposed at other locations of the chassis trailer 100 .

[0082] The transport vehicle in the embodiment of the present application can also be remotely controlled through a remote control system, for example, by operating a wireless remote control to achieve remote control of the transport vehicle, thereby improving control convenience and reducing labor intensity.

[0083] Based on the above transport vehicle, the present application also discloses a method for using the transport vehicle, which is applied to the above transport vehicle. Figures 1 to 16 , the use of the transport vehicle may include:
