Embodiment 1

[0030] Spreader for mounting cardan shafts of vertical rolling mills

[0031] The spreader for installing the cardan shaft of a vertical rolling mill according to the present invention comprises a steel frame 1, a closed support and a counterweight 5.

[0032] see now figure 1 , figure 1 It is a structural schematic diagram of the hanger implemented by the present invention. As shown in the figure, the steel frame 1 is a rectangular frame 3x0.6m reinforced and welded with angle steel ∠63*5 around it and some middle round steel Ф20mm, and a pair of lifting lugs 2 are arranged on both sides of the middle of the rectangular frame;

[0033] The closed bracket is fixed at one end of the steel frame 1, which is a square frame composed of angle steel 3 around and Ф24mm full-wire adjusting bolts 4 fixed with double nuts, and can be adjusted by adjusting the movable angle steel on the adjacent two sides and adjusting Bolts adjust the size of the square frame to suit the installation...

[0037] How to use the spreader for installing the cardan shaft of the vertical rolling mill

[0038] figure 2 It is a schematic diagram of the use state of the spreader implemented by the present invention. In the installation of cardan shafts of 9 vertical rolling mills in Jiujiang 1 million ton bar project, the weight of the cardan shafts is between 0.8t and 1.3t, calculated according to the heaviest cardan shaft of 1.3t, using the lever to balance the resistance *Resistance arm=power*power arm (1.3t*1m=0.65t*2m), that is, the counterweight is greater than or equal to 0.65t, and the counterweight of this project is about 0.8t, and the balance of the bracket is adjusted by a chain hoist, which can meet the 0.8 Cardan shaft installation between t-1.3t.

[0039] The method for using the spreader for installing the cardan shaft of a vertical rolling mill according to the present invention is characterized in that it comprises the following steps:

[0040] a. Provide a crane,...

Abstract

The invention discloses a hanger for mounting a universal shaft of a vertical mill. The hanger comprises a steel frame (1), a sealed bracket and a balance weight block (5). The hanger is characterized in that the steel frame (1) is a rectangular frame welded by angle iron at the periphery and a large amount of round steel; a pair of lifting lugs (2) are arranged at two sides of the middle of the rectangular frame; the sealed bracket is fixedly arranged at one end of the steel frame (1); the sealed bracket is a square frame formed by angle iron (3) at the periphery and adjusting bolts (4), and can adjust the size of the square frame by adjusting the movable angle iron at two adjacent sides and the adjusting bolts so as to be applicable to clamping universal shafts (6) with different diameters to enable the universal shafts (6) to be mounted; the balance weight block (5) is an iron barrel with the adjustable weight and is arranged at the other end of the steel frame (1). The hanger has the advantages of being simple in structure and convenient to fabricate, the universal shaft can be safely and stably conveyed to the mounting position directly, the construction efficiency is improved, the hanger is fast and convenient to maintain in the future and can be used for a long time, and the engineering construction cost is reduced.

Description

technical field [0001] The invention relates to a sling, in particular to a sling for installing a cardan shaft of a vertical rolling mill and a use method thereof. Background technique [0002] The vertical rolling mill in bar engineering is the core equipment of the whole project. In the installation of vertical rolling mills, it is very difficult to hoist the cardan shaft, and hoisting with the crane is not in place, and hoists need to be assisted for hoisting, and hoisting with hoists requires suspension points, and it is often impossible to find the correct suspension point in many cases, and the installation China's security is not guaranteed. [0003] Therefore there is above-mentioned inconvenience and problem in the installation method of known vertical rolling mill cardan shaft. Contents of the invention [0004] The object of the present invention is to propose a spreader for installing the cardan shaft of a vertical rolling mill. [0005] Another object of t...
