Description

Installation base for guide vane of steam turbine Technical Field The utility model relates to the technical field of turbine parts, in particular to a mounting base for a turbine guide vane. Background The mounting base for the guide vane of the steam turbine is a key component for mounting the guide vane in the steam turbine. The guide vane is an intermediate structure for connecting a turbine rotor (or stator) and a guide vane, and has the main functions of providing an accurate installation position and stable support for the guide vane, ensuring that the guide vane can accurately guide steam flow in the operation process of the turbine, thereby realizing efficient energy conversion. In the prior art, however, some device operators have spent more effort and time adjusting bit positions, which increases their effort. In such high-strength working conditions for a long time, operators are prone to fatigue, thereby affecting their accuracy and efficiency of operation. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a mounting base for a turbine guide blade, so that an operator can quickly position a drill bit to a next drilling position in the mounting process without replacing a mounting tool or readjusting the position of the whole mounting base, and the first shell and the second shell with the fixed bottom are detached, so that the drill bit is maintained and replaced. In order to achieve the above-mentioned purpose, provide a turbine is installation base for guide vane, including first base, the inside of first base is rotated and is connected with the spliced pole, the inside sliding connection of first base has the spacing subassembly that is used for limiting mechanism to remove in appointed within range, the inside sliding connection of spacing subassembly has the sliding block, the one end fixed connection sleeve of sliding block, telescopic inside sliding connection has the support column. According to the mounting base for the turbine guide vane, the limiting assembly comprises a sliding rail, and the outer part of the sliding rail is fixedly connected with the inner part of the first base. According to the mounting base for the turbine guide vane, a first spring is sleeved outside the support column, and a button is fixedly connected to the top of the support column. According to the mounting base for the turbine guide vane, the bottom of the supporting column is detachably connected with the fixing column, and the second spring is sleeved outside the fixing column.
