Description

TECHNICAL FIELD

[0001] The utility model belongs to hoisting and lifting technical field, concretely relates to a kind of balance beam for hoisting compressor upper cylinder. BACKGROUND

[0002] In the hoisting process, in order to reduce the requirement to hoisting machinery lifting height, keep the balance of the hoisted object, prevent the object from being extruded and deformed due to large horizontal component force and reduce the eccentric load, it is crucial to select or manufacture suitable balance beam. Taking the key core unit "ethylene three-machine unit" in ethylene industry as an example, with the development of ethylene industry, the capacity is continuously expanded, and the size and weight of the upper cylinder of ethylene three-machine unit are also continuously increased. Especially when the lifting height of the plant crane is limited, the use of conventional lifting rigging will reduce the hoisting stability, increase the safety hazard and cannot meet the safety hoisting requirements. Taking the hoisting of the upper cylinder of propylene refrigeration compressor in a plant as an example, the self weight of the compressor upper cylinder is 51 tons, the hoisting point size of the compressor upper cylinder is that the longitudinal distance between the lifting lugs is 4615 mm and the transverse distance between the lifting lugs is 1860 mm, and the distance between the upper cylinder after being hoisted and the middle surface needs to be at least >800 mm. However, due to the limitation of the installation height of the crane in the compressor plant, if the traditional hoisting method is used, the hoisting requirements cannot be met. If the roof of the compressor plant is removed, an 800-ton crawler crane needs to be used for hoisting, and there are problems of high hoisting cost and high risk coefficient.

[0003] Therefore, the applicant provides a balance beam structure with high strength, high bearing capacity, novel design and simple process, which can completely solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the technical problems mentioned in the background art, the utility model provides a balance beam for hoisting compressor upper cylinder, and the technical scheme is as follows:

[0005] A balance beam for hoisting compressor upper cylinder, characterized in that it comprises two balance beams, the balance beam comprises a balance beam body, the upper end surface of the balance beam body is designed with symmetrical upper lifting lugs, the lower end surface of the balance beam body is provided with symmetrical lower lifting lugs at both ends, the balance beam body is mainly composed of H-shaped steel, and reinforcing ribs are welded between the upper lifting lugs, the lower lifting lugs and the beam body.

[0006] Preferably, in the hoisting process, the center of gravity and the angle of the balance beam are better monitored. An angle pointer is arranged on the vertical side surface of the balance beam body.

[0007] Preferably, in order to save production cost and improve the strength of the beam body, the balance beam body is provided with a "H" type support body in the box type structure, and a soft filler is arranged between the "H" type support body and the inner wall of the balance beam body.

[0008] Preferably, the lower end surface of the balance beam is equipped with detachable pins on each group of lower lifting lugs, the both ends of the pins are limited by nuts, and the nuts are provided with anti-backoff measures.

[0009] The utility model has the following advantages:

[0010] The balance beam for hoisting the upper cylinder body of the compressor has the beneficial effects of the prior art as follows: the combination of the two balance beams avoids the problems of equipment unbalanced load and large horizontal component force caused by the low height of the compressor workshop and the limited lifting height, greatly improves the hoisting stability of the upper cylinder body of the compressor, reduces the production cost of the whole equipment through the special structural modification, and is safer, thereby achieving the effect of improving the productivity of enterprises.
