Description

Special well-tac-toe spreader for tail water elbow of hydro-generator set

technical field

The tool of the utility model belongs to the field of hoisting and hoisting equipment, in particular to a special hoisting tool for tailwater elbow pipes of hydroelectric generator sets.

Background technique

The tailwater elbow is an important pre-embedded part of the hydro-generator set. Its hoisting is mainly carried out by the bridge machine or truck crane in the factory after the main project of the factory building is completed. This not only prolongs the construction period, but also causes troublesome pouring procedures and increases construction cost. If the tailwater elbow is hoisted directly after the foundation of the hydroelectric generating unit is excavated, these construction defects will be well compensated. However, due to the complex conditions of the construction site after excavation, it is difficult for the truck crane to directly hoist the tailwater elbow in place, and the tower cranes on the construction site generally do not have the equipment capacity to hoist such a large tonnage.

Contents of the invention

The purpose of this utility model is to overcome the insufficient capacity of the existing hoisting equipment on the construction site, and provide a special well-shaped spreader for the tail water elbow of the hydroelectric generator set, which is used for hoisting the embedded parts of the tail water elbow and other units, reducing the construction cost. Working surface influence, in order to fully cross work.

The technical solution adopted by the utility model is a special well-shaped spreader for the tail water elbow of a hydroelectric generating set. The supporting cuboid, the column is a hollow circular tube, the upper and lower ends are fixed with flange connection plates, the beam and the column are fixedly connected by bolts on the flange connection plate, and two longitudinal beams are fixed in the middle of the beam.

The beams, columns and longitudinal beams of the utility model are connected with each other by bolts to form a stable support and assembled on site, so that large pre-embedded components such as tail water elbows of hydroelectric generating units can be installed in time under harsh construction site conditions, shortening the construction time. construction period.

The two ends of the beam are respectively fixed with side longitudinal beams. make the whole more stable.

The beam and the column are fixedly connected by bolts on the flange connection plate, which is convenient to connect.

The longitudinal beam is fixed at 1/3 of the distance from the end of the crossbeam.

It is also equipped with bottom channel steel with a knuckle angle not smaller than the arc of the tail water elbow. After arriving at the site, fix the bottom channel steel and the tail water elbow of the hydro-generator unit to facilitate towing and prevent damage to the tail water elbow during the towing process.

Longitudinal beams and beams are made of I-beams.

When hoisting the tail water elbow, the utility model well-tac-toe spreader is used together with chain hoists and other lifting equipment, which can lift the tail water elbow up and down, and can also pull and drag the tail water elbow in a short distance. The operation is simple and convenient. Work can be carried out independently in a large space, reducing labor intensity and improving safety factor. The utility model is convenient for disassembly, movement and repeated use.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described

As shown in Figure 1-4, a special well-tac-toe spreader for the tail water elbow of a hydro-generator set, which is composed of a beam 1, a column 3, and a longitudinal beam 12, is supported in three directions of X, Y, and Z. The cuboids are connected by bolts, the longitudinal beam 12 and the beam 1 are made of I-beam, the column 3 is a hollow tube, the upper and lower ends are fixed with flange connection plates 31, and the joints of the beam 1 and the column 3 are respectively fixed with The same flange connection plate 31, the two are connected by bolts, two longitudinal beams 12 are fixed in the middle of the beam 1, the longitudinal beams 12 are fixed at a distance of 1/3 from the end of the beam 1, and side longitudinal beams are fixed at both ends of the beam 1 The beam 2 and the side longitudinal beam 2 are made of channel steel.

The utility model is also equipped with a bottom channel steel 15 whose knuckle angle is not less than the arc of the tailwater elbow. After arriving at the site, fix the bottom channel steel and the tail water elbow of the hydro-generator unit to facilitate towing and prevent damage to the tail water elbow during the towing process.

When in use, as shown in Figure 4, first make the connection foundation on the ground, pre-embed the anchor hook 13 and the anchor bolt 8, it is best to fix a flange connection plate on the anchor bolt 8, and fix the column on the flange connection On the plate, tighten the anchor bolt 8. Before the tail water elbow is hoisted by the truck crane, bottom channel steels 15 are placed on the longitudinal ends of the bottom of the tail water elbow 14 respectively, and a 5-ton chain hoist 16 is hung on both ends of the crossbeam 1 to pass through the wire rope 18 and the tail water. The lifting lug 17 on the elbow is fixed, and the tail water elbow 14 is hauled for a short distance to the foundation pier 20, on which a channel steel 19 is mounted to facilitate the dragging of the tail water elbow.

After the tail water elbow 14 was hauled to the bottom of the utility model well-tac-toe spreader, four 5-ton hand chain hoists 16 were hung on the two longitudinal beams 12 to adjust the level of the nozzle on the tail water elbow 14, and at the same time The hoisting and installation of the tailwater elbow can be completed by fine-tuning the center position of the tailwater elbow 14 by using the jack erected between the 20 foundation piers of the tailwater elbow.

After the installation of the tail water elbow of the 1# machine is completed, the well-tac-toe spreader of the utility model is disassembled, and moved to the 2# unit by the tower crane on the construction site for assembly and reuse. It can also be applied to the elbow of the same type of machine.
