Description

Technical Field

[0001] The utility model relates to the technical field of thermal power plant construction, in particular to a tool for measuring the combined angle of V-shaped steel pipe concrete pillars of a super-large cooling tower. Background Art

[0002] As the installed capacity of power plants continues to increase, larger cooling towers have also emerged. At present, the cooling towers of 660MW and 1000MW power plants are getting larger and larger, and the height is getting higher and higher. For example, a super-large natural ventilation cooling tower is 242.4m high, with a water spraying area of ​​22,500㎡, an air inlet elevation of 19.5m, and a foundation diameter of 193.5m. It is currently the world's tallest cooling tower under construction. The corresponding natural ventilation cooling tower construction period is also getting longer and longer.

[0003] In order to shorten the construction period of the inclined pillars of the natural ventilation cooling tower, the power design unit of the power plant currently uses steel tube concrete V-shaped inclined pillars to replace the traditional reinforced concrete V-shaped inclined pillars for the first time. The main advantages are: short construction period, simple processing, good economy, low construction cost, single V-shaped inclined pillar steel pipe special-shaped parts can be factory-produced and assembled and hoisted on site, and the angle needs to be adjusted before assembly. The traditional angle measurement tool may have a complex structure and is inconvenient to carry, resulting in certain restrictions on its use on the construction site. The complex structure may also increase the difficulty of operation and reduce the measurement efficiency. The operator needs to go through a complex adjustment process to accurately measure the angle, which not only affects the accuracy of the measurement, but also may prolong the construction time. Secondly, the traditional measurement method may not be able to achieve real-time detection and review during the construction process, which may lead to the need for rework when the angle deviation is found in the later stage, increasing the construction cost and construction period. For this reason, a super-large cooling tower steel tube concrete V-shaped pillar combination angle measurement tool is designed, so that the cooling tower steel tube concrete V-shaped pillar can be quickly adjusted to the combination angle on the tire frame at one time to improve efficiency.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is not only suitable for the combined angle measuring tool of V-shaped concrete-filled steel tube pillars of super-large cooling towers, but also suitable for the combined angle measuring tool of X-shaped concrete-filled steel tube pillars of other super-large cooling towers. The utility model can meet the requirements of cooling tower steel tube concrete V- and X-shaped pillars with different design angles (generally any angle between 10 degrees and 40 degrees) through the main level and the auxiliary adjusting ruler angle. During construction, the combined frame steel pipe is adjusted to the combined position, and the combined angle measuring tool is used for measurement and adjustment, which can greatly improve the construction efficiency, reduce the steps of finding the center of the steel pipe and pulling the center size required by the traditional combination method, improve the overall construction efficiency and construction quality, and shorten the construction period.

[0023] See also Figure 1-6 In an embodiment of the utility model, a super-large cooling tower steel tube concrete V-shaped pillar combined angle measuring tool includes a main level ruler 1 and an auxiliary adjusting ruler 2. The main level ruler 1 and the auxiliary adjusting ruler 2 are connected by an arc-shaped telescopic angle ruler 3 and a connecting arc telescopic rod 4. The main level ruler 1, the auxiliary adjusting ruler 2, the arc-shaped telescopic angle ruler 3 and the connecting arc telescopic rod 4 are all made of aluminum alloy. The measuring angle of the main level ruler 1 and the auxiliary adjusting ruler 2 is 10 degrees to 40 degrees. The operator only needs to separate the main level ruler 1 and the auxiliary adjusting ruler 2 to use it.

[0024] See also Figure 1-3 In one embodiment, in this embodiment, preferably, the arc-shaped telescopic angle ruler 3 and the connecting arc telescopic rod 4 are connected to the main level ruler 1 and the auxiliary adjustment ruler 2 through a connecting piece. Further, the connecting piece is specifically a locking bolt 6. The main level ruler 1, the auxiliary adjustment ruler 2, the arc-shaped telescopic angle ruler 3 and the connecting arc telescopic rod 4 are installed and removed by rotating the locking bolt 6 clockwise or counterclockwise, thereby improving the efficiency of subsequent use and assembly.

[0025] See also Figure 1-3In one embodiment, in this embodiment, preferably, the surface of the arc-shaped telescopic angle ruler 3 is provided with an angle ruler scale, the arc-shaped telescopic angle ruler 3 includes four arc-shaped telescopic strips of the same length, and the surfaces of the four arc-shaped telescopic strips are provided with scales of the same angle. Furthermore, through the setting of the scale, the opening angle of the main horizontal ruler 1 and the auxiliary adjustment ruler 2 can be observed in real time. Secondly, the four arc-shaped telescopic strips are tightly fitted and plugged in, and the operator pulls the main horizontal ruler 1 or the auxiliary adjustment ruler 2 to extend or retract the four arc-shaped telescopic strips.

[0026] See also Figure 1 In one embodiment, in this embodiment, preferably, a mounting groove is provided on the surface of the main level 1, and a bubble level 5 is provided inside the mounting groove. Under the action of the bubble level 5, it is better to observe whether the main level 1 is in a horizontal state when placed. If it is not in a horizontal state, the main level 1 can be adjusted by the bubble level 5.

[0027] The working principle and use process of the utility model are as follows: when the angle of a V-shaped concrete-filled steel tube pillar is measured by using the tool, the angle measuring tool is adjusted to a preset design angle, that is, the angle between the main level 1 and the auxiliary adjusting ruler 2 is adjusted and locked, and then the main level 1 is placed horizontally, the auxiliary adjusting ruler 2 is made close to the center line of one side pillar, and the angle of the pillar on the other side and the horizontal direction is adjusted according to the angle between the auxiliary adjusting ruler 2 and the horizontal direction, until the pillars on both sides are parallel or fitted with the measuring tool, thereby spot welding the concrete-filled steel tube V-shaped pillar to fix the combined angle; when the angle of the assembled concrete-filled steel tube V-shaped pillar is detected and verified by using the tool, the main level 1 is placed horizontally, the auxiliary adjusting ruler 2 is rotated to fit or be parallel to the pillar, and then the angle on the arc-shaped telescopic angle ruler 3 is read, and the angle is the angle of the concrete-filled steel tube V-shaped pillar. If the angle is within the allowable deviation range of the specification or design, the requirement is met, otherwise it does not meet the requirement.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
