Description

Hoisting tool for installing reactor supporting beam

Technical Field

The utility model relates to a lifting device, in particular to a lifting device for lifting a reactor internal part-supporting beam.

Background

In the field of chemical device construction, almost every device is not separated from a reactor in shape and detail, the main engineering content of reactor construction is concentrated on internal part installation, and the hoisting and installation of a supporting beam are links integrating key points, difficulties and dangerous points. Every engineer must face two challenges when installing reactor support beams, especially large or special support beams: 1) and (4) hoisting. 2) How to level the installation. How to safely and economically hoist and level is a problem that countless constructors are always exploring.

In the current engineering construction, the main method for installing and constructing the reactor internals and the supporting beams is as follows:

because the reactor supporting beam has larger size, heavier mass and irregular shape, a special hoisting ring is not arranged when the reactor supporting beam leaves a factory, and a special hoisting tool is not matched. During construction, a crane is mostly adopted to bind the supporting beam or penetrate into the hole of the supporting beam body for hoisting by using a steel wire rope or a hanging strip. The concrete hoisting process is as follows: firstly, a supporting beam falls into the reactor by vertical hoisting, secondly, the supporting beam is unhooked in the reactor and adjusted to be two-point horizontal hoisting, and finally, the installation work is finished. The method has the following defects: 1) the hoisting process is unsafe, the hoisting mode is adopted, the hoisting is easy to slide, the hoisting mode is adopted, and the peripheral edges and corners of the hoisting holes are easy to cut the slings or the steel wire ropes. 2) The installation is slow, the mechanical use efficiency is low, the construction in the reactor is limited, and the operations of hook falling, hook unhooking, hook hooking, hoisting and the like are inconvenient, so that the leveling installation is complicated and slow.

SUMMERY OF THE UTILITY MODEL

The utility model provides a lifting device for a reactor supporting beam installation for solving the technical problem that exists among the well-known technology, adopt this instrument can accomplish a reactor supporting beam's installation fast, safely, economically.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a lifting device for installation of a reactor supporting beam, includes with a supporting beam upper end articulated hoist and mount tool to lock, adjustment tool to lock and chain block, the one end of adjustment tool to lock is articulated with a supporting beam's lower tip, the other end with the couple of chain block is connected, during an adjustment supporting beam, the chain block with hoist and mount tool to lock all hangs on the hoist and mount lifting hook.

The lifting lockset has the same structure with the adjusting lockset, and comprises two clamp plates which are arranged face to face, a stiffening connecting plate and two end pin shafts are arranged between the two clamp plates, and two ends of each end pin shaft are connected with a limiting lock nut.

The chain block is a manual hinge.

The utility model has the advantages and positive effects that: by adopting the combined structure of the hoisting lock, the adjusting lock and the chain block, when the supporting beam is installed in the reactor, the leveling and the installation of the supporting beam can be completed only by connecting the adjusting lock and the chain block without hook dropping and hook unhooking, the operation is simple, the construction speed is high, and the efficiency is high; the hoisting lock and the adjusting lock are connected with the supporting beam by pin shafts, and the hoisting lock and the adjusting lock are safe and reliable. And this the utility model discloses still have the structure light, make simple and convenient, application scope is wide, convenient operation, can improve advantages such as mechanical availability factor, repeatedly usable, successfully solved traditional reactor internals-a supporting beam hoist and mount insecurely, install slowly, mechanical availability factor low grade problem, can realize vertical hoist and mount, rotatory leveling, can not unhook high-efficient, safe, economically accomplish reactor internals-a supporting beam's installation operation.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1 to 3, a lifting tool for mounting a reactor support beam comprises a lifting lock 2, an adjusting lock 3 and a chain block 4, wherein the lifting lock 2 is hinged to the upper end of a support beam 1, one end of the adjusting lock 3 is hinged to the lower end of the support beam 1, the other end of the adjusting lock is connected with a hook of the chain block 4, and when the support beam 1 is adjusted, the chain block 4 and the lifting lock 2 are both hung on a lifting hook 5.

In this embodiment, hoist and mount tool to lock 2 with adjustment tool to lock 3 structure is the same, including two splint 7 that face to face sets up two be equipped with stiffening connecting plate 8 and two tip round pin axles 9 between the splint 7 the both ends of tip round pin axle 9 are connected with spacing lock nut 10. The chain block 4 is a manual hinge, so that electricity connection can be avoided, and safety is guaranteed.

Referring to fig. 1, when the support beam 1 is hoisted into the reactor 6 by the hoisting lock 2, the adjusting lock 3 may be connected to the lower end of the support beam 1, or the adjusting lock 3 may not be connected, but the adjusting lock 3 and the chain block 4 are connected in the reactor 6 after the support beam 1 is hoisted into the reactor 6. The installation is completed by adjusting the level of the support beam 1 by adjusting the hinge 10.
