Description

Technical Field

[0001] This invention relates to the field of gas turbines, and more specifically to an electrically liftable gas turbine transfer trolley. Background Technology

[0002] A gas turbine is an internal combustion engine that uses a continuously flowing gas as its working fluid to drive a high-speed rotating impeller, converting the energy of fuel into active power. It is a type of rotary impeller-type thermal engine. In the main flow of air and gas, the gas turbine cycle consists of only three major components: the compressor, the combustion chamber, and the gas turbine. This cycle is commonly referred to as a simple cycle, and most gas turbines adopt this design. The compressor draws in air from the external atmosphere and compresses it stage by stage by stage using an axial-flow compressor, increasing the air pressure and temperature. The compressed air is then forced into the combustion chamber where it mixes with the injected fuel and combusts to generate high-temperature, high-pressure gas.

[0003] When the gas turbine inside the soundproof enclosure needs maintenance or replacement, the limited space inside the enclosure prevents workers from completing all maintenance and replacement work within the enclosure. Therefore, it is necessary to remove the core components of the gas turbine (gas generator, power turbine, etc.) from the enclosure and transfer them to a designated transfer or maintenance area with sufficient operating space. Thus, a replacement trolley is required to load the gas turbine onto it during disassembly and then transfer it via casters; or to load the new gas turbine for replacement, move it to the side of the enclosure via casters, and then move the gas turbine inside.

[0004] When the gas turbine's underframe is high off the ground, the transfer trolley needs to be set high as well to ensure it aligns with the underframe during turbine loading and unloading. This high trolley, combined with the gas turbine, results in a high center of gravity, posing a risk of tipping over during transport. Most existing transfer trolleys have some height adjustment capabilities, using hydraulic or threaded mechanisms. However, these mechanisms have short strokes and become difficult to adjust after the gas turbine is loaded due to its weight.

[0005] Therefore, this invention proposes an electrically liftable gas turbine transfer trolley to solve the above problems. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing an electrically liftable gas turbine replacement trolley.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: an electrically liftable gas turbine replacement trolley, including a trolley base, a fine adjustment mechanism installed on the lower surface of the trolley base, an adjustment mechanism installed on the upper surface of the trolley base, and a locking mechanism installed on the surface of the adjustment mechanism; The adjustment mechanism includes hollow boxes fixedly connected to the upper surface of the trolley base in a rectangular array. A drive motor is fixedly connected inside the hollow box. A threaded screw is fixedly connected to the output end of the drive motor. A threaded cylinder is threaded onto the surface of the threaded screw. One end of several threaded cylinders is fixedly connected to a support plate. A guide rail is slidably connected in a path array inside the support plate. Guide wheels are rotatably connected in a rectangular array on the upper surface of the guide rail. A drive mechanism for moving the guide rail is installed on the surface of the support plate. A guide rod corresponding to the guide rail is fixedly connected in a path array on one side wall of the support plate.

[0008] In a preferred embodiment, the fine-tuning mechanism includes a support plate fixedly connected in a rectangular array to the lower surface of the trolley base. A pneumatic push rod is fixedly connected to the lower surface of the support plate, and telescopic rods are fixedly connected to both sides of the lower surface of the support plate. The pneumatic push rod and several telescopic rods are fixedly connected to a moving wheel on their surfaces.

[0009] In a preferred embodiment, the fine-tuning mechanism further includes a control box fixedly connected to the middle of the upper surface of the trolley base and having a control unit inside. The upper surface of the control box is fixedly connected to a counterweight block for increasing the weight of the trolley base, and the moving wheels are fixedly connected in a rectangular array to the four corners of the lower surface of the trolley base.

[0010] In a preferred embodiment, the driving mechanism includes through slots formed on both sides of the surface of the bearing plate. A threaded rod is rotatably connected to the inside of the through slot via a bearing seat. A connecting block that is fixedly connected to the guide rail and corresponds to one of the guide rods is threadedly connected to the surface of the threaded rod. A driving gear is fixedly connected to one end of each of the two threaded rods.

[0011] In a preferred embodiment, the drive mechanism further includes a gear ring that meshes with the surfaces of two drive gears. The gear ring is rotatably connected to the interior of a support plate. A servo motor with its output end fixedly connected to one of the drive gears is fixedly connected to the interior of the support plate. An inclined plate is fixedly connected to one side of the guide rail. The connecting block is slidably connected to the through groove.

[0012] In a preferred embodiment, the locking mechanism includes a support rod fixedly connected to the upper surface of the counterweight and connected to an existing electromagnetic coil. The surface of the support rod is provided with two corresponding support frames. One of the support frames is slidably connected to the support rod, and the other support frame has a limit mechanism installed inside. The two sides of the two support frames are respectively fixedly connected to corresponding threaded cylinders.

[0013] In a preferred embodiment, the limiting mechanism includes sliding grooves arranged in a ring array on the inner arc surface of another support frame. A movable rod is slidably connected inside the sliding groove. A guide block corresponding to the support rod is slidably sleeved on the surface of several movable rods. A friction block corresponding to the guide block and the support rod is fixedly connected to one end of the movable rod.

[0014] In a preferred embodiment, the locking mechanism further includes a support base fixedly connected in a path array to the middle of the inner top wall of the bearing plate. Pressure sensors are fixedly connected in a rectangular array on the upper surface of the support base. A pad corresponding to the support base is fixedly connected to the upper surface of several pressure sensors. Several corresponding push plates are attached to the surface of the support base. Electric push rods fixedly connected to the support base are fixedly connected in a ring array on the lower surface of the push plates.

[0015] The beneficial effects of this invention are as follows: Based on the cooperation of the adjustment mechanism and the fine-tuning mechanism, when the gas turbine inside the soundproof enclosure needs to be repaired or replaced, the position of the bearing plate and the guide rail is adjusted based on the cooperation of the drive motor, the screw, and the threaded cylinder, so that the guide rail can be connected with the soundproof enclosure, allowing the gas turbine to slide on the guide rail. The guide wheel guides the gas turbine while controlling its movement speed. At the same time, the fine-tuning mechanism can move the bearing plate within a small range as needed, making the connection between the bearing plate and the guide rail more precise, thus completing the replacement of the gas turbine. Furthermore, the screw and threaded cylinder designed on the replacement trolley have a large stroke, which can effectively lower the overall center of gravity of the gas turbine and the trolley, preventing overturning. Based on the locking mechanism and other structural features, when the drive motor and threaded screw experience power failure or overload, the electromagnetic coil is quickly energized, causing the support rod to generate magnetic force, which attracts the friction block and the moving rod, making the friction block stick tightly to the surface of the support rod. This increases the friction between the guide block and the support rod, while the threaded cylinder is fixedly connected to the support frame, enabling rapid locking of the threaded cylinder and limiting its position to prevent the bearing plate from suddenly sinking and affecting the gas turbine. Based on the cooperation of pressure sensors and support structures, the gas turbine moves onto the pad via guide rails for support. The pressure sensors provide comprehensive real-time monitoring of the pressure applied to the gas turbine. When a pressure sensor malfunctions, the electric push rod and push plate cause deformation of the support and pad, applying support force to the gas turbine, adjusting its balance, and quickly adjusting a specific angle of the bearing plate individually via different threaded screws and threaded cylinders, ensuring that the gas turbine remains balanced throughout its movement.
