Description
Technical Field
The utility model belongs to the technical field of ventilators, and particularly relates to a slidable fixing device for a large ventilator.
Background
With the rapid development of domestic thermal power generation and metallurgical technology, the exhaust gas flow and temperature of a power station boiler, a sintering machine and the like are higher and higher, the size of a ventilator is larger and larger, and the thermal expansion of a machine body is more and more severe. However, the ventilator housing is usually directly fixed to the concrete foundation by anchor bolts and is fully restrained, when the blower is operated, the housing is heated to expand, the expansion force generated by the thermal expansion directly acts on the rigid concrete foundation to damage the foundation, and meanwhile, the reaction force of the concrete foundation acts on the blower housing, which may also cause damage to the blower housing.
Disclosure of utility model
The utility model aims to overcome the defects and provide a slidable fixing device for a ventilator, which can absorb the expansion displacement generated when the ventilator thermally expands, thereby protecting a blower shell and a concrete foundation.
The technical scheme of the utility model is as follows: a slidable fastening device for a ventilator, the device comprising: concrete foundation, embedded plate, casing support and fixed subassembly, the embedded plate on set up mounting hole I, the casing support on set up mounting hole II, embedded plate and concrete foundation fixed connection, the casing support lay on the embedded plate, fixed subassembly one end pass mounting hole II, mounting hole I and concrete foundation fixed connection in proper order, the other end presses the casing support on the embedded plate, its characterized in that: the fixing assembly consists of a nut, an upper pressing plate, a lower pressing plate, a sleeve group and an anchor bolt, wherein the sleeve group, the lower pressing plate, the upper pressing plate and the nut are sequentially arranged on the anchor bolt, the sleeve group comprises an O-shaped sleeve with internal threads and a T-shaped sleeve with external threads, the O-shaped sleeve with internal threads is arranged on the T-shaped sleeve with external threads, the lower pressing plate is circular, a mounting hole III is formed in the middle of the lower pressing plate, the upper pressing plate is circular, a mounting Kong is formed in the middle of the lower pressing plate, the outer diameter of the sleeve group is larger than the diameter of the mounting hole I, the diameter of the mounting hole II is larger than the outer diameter of the sleeve group, the diameter of the mounting hole III is larger than the outer diameter of the sleeve group, the diameter of the mounting hole IV is smaller than the diameter of the mounting hole II, and the outer diameter of the upper pressing plate is larger than the diameter of the mounting hole III.
The utility model has the beneficial effects that: the sleeve group include the O type sleeve pipe of taking the internal screw thread and the T type sleeve pipe of external screw thread, the O type sleeve pipe of taking the internal screw thread install on the T type sleeve pipe of external screw thread, the high accessible screw thread of sleeve group is adjusted from top to bottom, can effectually guarantee that the nut compresses tightly the top board when locking when the sleeve group height is slightly higher than the holding down plate height, and holding down plate and casing support do not receive the locking force of nut. Meanwhile, the diameter of the mounting hole II is larger than the outer diameter of the sleeve group, and the shell support can perform certain displacement in the horizontal direction. In addition, because the diameter of the mounting hole IV is smaller than the outer diameter of the sleeve group, the outer diameter of the lower pressing plate is larger than the diameter of the mounting hole II, and the outer diameter of the upper pressing plate is larger than the diameter of the mounting hole III, the upper pressing plate can limit the lower pressing plate to move in the height direction, and the lower pressing plate can limit the shell support to move in the height direction. When the fan casing is heated and expanded, the casing can perform certain displacement in the horizontal direction, so that the damage of the casing support to the concrete foundation can be effectively avoided, and the damage of the reactive force generated by the concrete foundation to the fan is also avoided.
