Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as Figure 5 to Figure 12 As shown, the equipment hoisting equipment includes:

[0033] The beam 1 is a trapezoidal box-shaped structure with a large top and a small bottom, and is assembled and welded by steel plates. Two rows of screw holes 11 are evenly spaced on both ends of the upper surface of the beam 1 .

[0034] The lifting lug 2 includes the lug plate 21. There are four lug plates 21 in this embodiment, which are opposite to each other and symmetrically arranged in the middle of the beam 1. The lug plate 21 is provided with a shaft hole 22. In this embodiment The outside of the lug plate is also provided with a lug reinforcing ring plate 23, and the inside of the lug plate is also provided with a lug reinforcing rib plate 24 to increase the strength of the lug. The lug reinforcement ring plate and rib plate can be set ...

Abstract

The invention relates to a hanger for hoisting equipment, which comprises a beam, wherein a hanging lug is arranged on the beam. The hanger is characterized in that: the hanging lug is arranged on the middle part of the beam, and comprises a hanging lug plate; a shaft hole is formed on the hanging lug plate; and a pin shaft passes through the shaft hole, so that the hanger is connected on an assembly of a hook pulley block of a crane. The hanger can be connected with a hanging arm of the crane directly, a sling for connecting the beam and a hook of the crane and the hook of the crane which are arranged above the beam in the prior art are saved, and the hoisting height of equipment is reduced, so the length, which is required by the hoisting equipment, of an arm lever of the crane is reduced, and the specified hoisting capacity of the crane is expressed and improved fully. Simultaneously, the construction preparation workload required before the equipment is hoisted can be reduced, and the friction between the sling and the hanging lug of the equipment can be reduced during the hoisting of the equipment to prevent the sling from being abraded, and thus, safety of hoisting is ensured.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to a hoisting tool for equipment hoisting. Background technique [0002] In equipment hoisting, in order to improve the stress conditions of equipment, prevent equipment deformation, and facilitate hoisting, etc., it is generally necessary to set up a lifting beam as an auxiliary tool for equipment hoisting. The hanging beams are the three structural forms listed in the Petrochemical Industry Standard of the People's Republic of China "Construction Technology Standards for Large-scale Equipment Hoisting Engineering" SH / T3515-2003, namely tube-sheet hanging beams, supporting hanging beams and adjustable-length hanging beams. Such as figure 1 , figure 2 and image 3 shown. [0003] When using the above hanging beam to hoist the equipment, a sling should be installed above the hanging beam to connect with the hook of the crane. Setting the sling above the lifting beam is equi...
