Description

Steam pipeline sweeps target plate fixing device Technical Field The utility model relates to the technical field of target plate purging equipment, in particular to a target plate purging fixing device for a steam pipeline. Background Unavoidable impurities such as rust and welding slag remain in the pipeline during the steam pipeline piping process of the steam engine. If these impurities are brought into the high-speed rotating steam turbine, the steam turbine set is stopped due to the exceeding of the vibration value, the rotor of the steam turbine is damaged directly more seriously, and even the whole steam turbine set needs to be replaced, so that great economic loss is caused. Therefore, before the steam unit is put into use, in order to ensure normal operation, steam is required to purge the inside of the pipeline, and the purging effect is based on the detection result of the target plate trace. The target plate is made of materials and dimensions specified by the standard, and is used for checking the quality standard of the blowpipe. The target plate is installed on the target frame, and fixing device only fixes one end of the target frame, and the other end is embedded in the groove, and huge pressure and steam flow can be produced during purging, and the target plate can vibrate when the target plate is purged, so that the possibility of breakage of the target plate during purging is increased, and the judgment of the purging effect is influenced. Disclosure of utility model In order to overcome the defect that the installation of a target plate is unstable in the prior art and the judgment of the structure is affected, the utility model provides a fixing device for a steam pipeline purging target plate. The technical scheme includes that the target plate fixing device for steam pipeline blowing comprises a mounting sleeve, a target frame is fixedly arranged in the mounting sleeve, a target plate is fixedly arranged on the side face of the target frame, an upper fixing rod is arranged between the mounting sleeve and the target frame in a penetrating manner, a lower fixing rod is arranged at the other end of the target frame in a penetrating manner, a buffer rubber block is sleeved outside the target frame, a through groove is formed in the buffer rubber block, and a plurality of second springs are fixedly arranged in the through groove. The steam pipeline sweeps target plate fixing device, the side fixedly connected with of installation sleeve goes up the go-between, go up the lower extreme fixedly connected with pipeline of go-between, the lower extreme fixedly connected with of pipeline goes down the go-between, the target frame runs through in the inside of pipeline.
