Description

Technical Field

[0001] The utility model relates to the technical field of turntable support structures, in particular to a support structure for a pneumatic torque guide vane turntable. Background Art

[0002] As people pay more and more attention to energy conservation and emission reduction, the development of power generation technology using gas waste heat and waste pressure has become an inevitable trend. Among them, the radial flow turbine structure is one of the typical structures, and adding an adjustable guide vane structure at the turbine inlet can make the turbine have a higher power generation efficiency in a larger flow range.

[0003] At present, due to the large aerodynamic torque of the adjustable guide vane structure, if the turntable is directly matched with the annular support parts, the friction of the contact surface will be very large when the turntable rotates, which will not only cause the parts to wear quickly, but also increase the burden on the adjustment structure. In addition, the installation of the turntable and the support parts is cumbersome and inconvenient to install and disassemble.

[0004] Therefore, in order to solve the above problems, a support structure for an aerodynamic torque guide vane turntable is proposed. Utility Model Content

[0005] The utility model aims to provide a support structure for a pneumatic torque guide vane turntable, comprising a guide vane turntable and a support seat arranged below the guide vane turntable, wherein T-shaped mounting grooves are provided at upper, lower, left and right positions below the guide vane turntable, a T-shaped mounting block is provided inside the T-shaped mounting groove, a mounting plate 1 is provided outside the T-shaped mounting groove, the four outer corners of the mounting plate 1 are fixed to the outside of the guide vane turntable by fastening bolts 1, a spherical slider is provided below the T-shaped mounting block, the spherical slider is inserted into the spherical slide groove through a spherical insertion channel, a mounting plate 2 is provided outside the spherical insertion channel, and the four outer corners of the mounting plate 2 are fixed to the outside of the support seat by fastening bolts 2.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] The utility model realizes the connection between the guide vane turntable and the support seat by opening four T-shaped installation grooves on the guide vane turntable, installing T-shaped installation blocks inside the four T-shaped installation grooves, and arranging a spherical slider under the T-shaped installation block, and sending the spherical slider into the spherical slider opened on the support seat, thereby realizing the connection between the guide vane turntable and the support seat, and leaving a gap between the guide vane turntable and the support seat to prevent friction between the guide vane turntable and the support seat during rotation, thereby increasing the service life of the guide vane turntable.

[0008] The utility model arranges a mounting plate one outside the T-shaped mounting groove, and arranges a T-shaped protrusion on the inner side of the mounting plate one, and the T-shaped protrusion is filled into the inside of the T-shaped mounting groove. On the one hand, the arrangement of the T-shaped protrusion can prevent the T-shaped mounting block from shaking during use. On the other hand, dismantling the fastening bolt one can facilitate the removal of the T-shaped mounting block. Similarly, a spherical protrusion is arranged on the inner side of the second mounting plate, and the spherical protrusion is filled into the inside of the spherical insertion channel to prevent the spherical slider from deviating when sliding in the spherical slide groove. On the other hand, dismantling the fastening bolt two can facilitate the removal of the spherical slider, thereby facilitating the separation of the support seat and the guide vane turntable, and facilitating installation and disassembly.
