Description
Technical Field
The utility model relates to the technical field of construction equipment, in particular to a tool for quickly adjusting three-unit combination installation in a power station boiler.
Background
All three devices (an economizer, a superheater and a reheater) of the supercritical tower boiler are arranged in a hearth in a horizontal snake-shaped structure, and the three devices in the boiler are sequentially suspended in series from a boiler top suspension device through an internal suspension pipe. Therefore, three devices in the furnace are arranged in a closed space formed by the surrounding water-cooled walls and the ceiling tube panels, and are large in number, wide in size and heavy in mass, so that the lifting device can only be used for lifting by arranging the furnace bottom at the top of the lifting device. According to the installation and adjustment mode, the speed of combined welding of the internal suspension pipes is far behind the hoisting speed of three devices in the furnace, and large batches of hand-pulling chain blocks, steel wire ropes and snap rings need to be put into the furnace in a short time, but if large batches of hoisting tools are purchased, the cost for executing projects is not different from the cost for increasing the cost for executing the projects. Therefore, how to quickly carry out hoisting and adjustment is the key for solving the overall installation progress and reducing the cost investment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems in the existing construction process, and aims at solving the problems of large requirements, high damage rate and uneven quality of lifting tools of a lifting tool in the power station boiler by innovatively designing a rapid adjustment three-device combined installation tool in the power station boiler aiming at the installation mode of lifting three devices in the boiler by adopting the mode of arranging a furnace bottom on the top of a lifting device for lifting.
In order to achieve the purpose, the utility model adopts the technical scheme that: a quick adjustment three-unit combined installation tool in a power station boiler comprises an adjusting rod, a double-thread screw rod and a T-shaped hook plate; adjusting nuts are arranged at two ends of the adjusting rod, and each adjusting nut is connected with a double-thread screw rod; the other end of the double-thread screw rod is connected with the T-shaped hook plate.
Further preferably, the adjusting nut at one end of the adjusting rod is a left-hand thread, and the other end of the adjusting rod is a right-hand thread.
Preferably, both ends of one double-thread screw rod are right-handed threads, one end of the other double-thread screw rod is right-handed threads, and the other end of the other double-thread screw rod is left-handed threads.
Further preferably, two ends of the double-thread screw rod are respectively sleeved with locking nuts.
Further preferably, the left-hand thread or the right-hand thread is a fine thread.
The tool for quickly adjusting the three-unit combination in the boiler of the power station boiler has the advantages that:
reduce construction tool, optimize the construction: the utility model directly converts the hand chain block, two sets of steel wire ropes and the snap ring into a set of rapid adjustment tool according to the design requirements, thereby solving the problem of complicated construction;
the safety is higher: the thread pitch of the fine thread is small, the thread lead angle is small, the self-locking performance is good, the anti-vibration and anti-loosening capacity is strong, and the self-locking of the quick adjusting tool is realized through the matching of the adjusting rod, the double-thread screw rod and the locking nut. The problems that a clamp ring and a steel wire rope of a traditional tool are easy to fall in high altitude, and a chain is easy to slide and clamp when a chain is reversed by hand pulling are solved;
the adjustability is better: the utility model is suitable for hanging adjustment of the biplate assembled hanging tube bank, can quickly hook the tube bank and quickens the adjustment speed. The double-thread screw rod can be disassembled and replaced, has multiple specifications and multiple sizes, and is matched with the adjusting rod to realize the installation of three devices in the furnace with different specifications and quick adjustment of intervals
The construction reliability is higher: the T-shaped hook plate is perfectly attached to the actual snakelike tube panel, so that the tube panel is prevented from being scratched, bruised and pulled, and compared with a hoisting tool of a steel wire rope, a hand-pull chain block and a clamping ring, a protective cushion layer or an anti-abrasion device is not required to be added on the equipment protection, so that the method is simple and effective;
the construction period and the economic benefit are obvious: the left-handed and right-handed threaded adjusting rod and the double-threaded screw rod can be externally processed or adopt a pipeline supporting and lifting device, a large amount of expenses for purchasing hand-pulling chain blocks, snap rings and splicing steel wire ropes are saved, and the economic benefit is obvious.

Detailed Description
For better understanding of the present invention, the technical solution of the present invention will be described in detail with reference to the following embodiments, but the present invention is not limited thereto.
As shown in fig. 1 and fig. 2, the tool for quickly adjusting the three combinations in the boiler of the utility boiler comprises a left-right screw thread adjusting rod 1, a double-thread screw rod 2, a T-shaped hook plate 3 and a locking nut 4.
Wherein, the two ends of the left-right screw thread adjusting rod 1 are respectively provided with a left-handed fine thread adjusting nut and a right-handed fine thread adjusting nut.
The double-thread lead screw 2 comprises an upper double-thread lead screw and a lower double-thread lead screw.
The upper double-thread screw rod is a double right-handed fine-thread screw rod, one end of the upper double-thread screw rod is matched and connected with a right-handed fine-thread adjusting nut of the right-handed thread adjusting rod 1, and the other end of the upper double-thread screw rod is in threaded connection with a T-shaped hook plate 3.
The lower double-thread screw rod is a left-right fine-thread screw rod, namely, one end of the screw rod is a left-right fine-thread screw, and the other end of the screw rod is a right-right fine-thread screw. The left-handed fine thread end of the lower double-thread screw rod is in matched connection with the left-handed fine thread adjusting nut of the left-handed and right-handed thread adjusting rod 1, and the right-handed fine thread end is in threaded connection with a T-shaped hook plate 3.
