Description

Technical Field

[0001] The utility model relates to the technical field of guide rail seats, in particular to an adjustable guide rail seat for nuclear power equipment. Background Technique

[0002] The guide rail seat of nuclear power equipment is a key component in nuclear power equipment. It mainly plays the roles of supporting, guiding and positioning the guide rail. The guide rail seat is usually made of metal or other strong materials to ensure that it can withstand various forces and torques generated during the operation of nuclear power equipment. For the existing guide rail seats, during use, bolts are usually used to connect and install the fixing plate to fix the guide rail seat. Since the guide rail needs to be installed and positioned according to different height conditions during installation, using a positioning type guide rail seat is likely to cause restrictions on its height distance, resulting in inaccurate installation positions of the guide rail, affecting the stable operation of the equipment. Therefore, we propose an adjustable guide rail seat for nuclear power equipment to solve the problems mentioned above. Content of the Utility Model

[0003] In order to overcome the problems of the existing guide rail seats, which usually use bolts to connect and install the fixing plate to fix the guide rail seat. Since the guide rail needs to be installed and positioned according to different height conditions during installation, using a positioning type guide rail seat is likely to cause restrictions on its height distance, resulting in inaccurate installation positions of the guide rail, affecting the stable operation of the equipment.

At the same time, the position and height of the guide rail seat are accurately controlled to ensure precise cooperation with surrounding components. After the telescopic block adjusts the position of the guide rail, the pin is inserted and fixed to ensure the limit fixation of the telescopic block supporting the guide rail, reducing the safety risk caused by the movement of the telescopic block. And the pressure plate is pressed and positioned after the guide rail is fixed to ensure the tight connection between the guide rail seat and the guide rail, preventing the guide rail from loosening or displacing during operation. By adopting the filling plate to assist the pressure plate in pressing and positioning, the gap between the pressure plate and the guide rail seat can be filled to form a more tight fixed connection, preventing it from loosening or displacing during operation, and at the same time absorbing and dispersing part of the vibration and impact. And an auxiliary frame is installed at the bottom of the fixing plate to be installed and supported according to different height requirements to provide additional support. Two sets of level gauges are used to measure during the installation of the guide rail seat to reflect the actual installation state of the guide rail seat, so that the guide rail seat meets extremely high precision requirements during the installation process, ensuring the precise adjustment and installation of the guide rail seat.
