Abstract

The utility model discloses an auxiliary lifting appliance for a cubic heat exchange core, which comprises a rectangular lifting appliance body, wherein a lifting hole and a plurality of bolt holes are sequentially formed in the side wall of the lifting appliance body, the bottom of the lifting appliance body is a triangular inclined surface, the shape of the inclined surface is matched with the shape of the outer side wall of the cubic heat exchange core to be lifted, and a U-shaped groove is formed in the center of the bottom of the lifting appliance body along the length direction of the lifting appliance body. The depth of the U-shaped groove is greater than the height of the raised lug plates on the side wall of the heat exchange core, and the opening width of the U-shaped groove is slightly greater than the thickness of the raised lug plates. When the heat exchange core is lifted, the raised lug plates are clamped in the U-shaped grooves, so that the damage of the raised lug plates caused by rope binding in the process of the heat exchange core is avoided, and the using effect of a product is not influenced; the inclined plane fully contacts with the outer wall of heat exchange core, has enlarged the stress surface of handling, has guaranteed the security and the stability of transfer process, has prevented the landing of heat exchange core.

Description

Auxiliary lifting appliance for cubic heat exchange core body

Technical Field

The utility model relates to the technical field of hoisting equipment, in particular to a horizontal hoisting auxiliary tool for a cubic heat exchange core.

Background

The structural form of plate heat exchanger equipment presents diversified trend, and a block plate and frame heat exchanger is welcomed by customers because of the advantages of high pressure bearing, high temperature resistance, high heat exchange efficiency, small occupied area and the like. This plate heat exchanger's heat transfer core is piled up neatly by the slab successive layer and is become cubic shape, and weight reaches several tons, has bellied otic placode to be used for being connected with outer frame in four angular regions. Because the heat transfer core can not design the lug, can only adopt the rope to bind the hoist and mount to the heat transfer core when the conventionality is to the heat transfer core handling, can cause the damage to protruding otic placode at the handling in-process, influence the result of use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an auxiliary horizontal hoisting tool for a cubic heat exchange core body, and the auxiliary horizontal hoisting tool is used for solving the problem that the cubic heat exchange core body is damaged by conventional hoisting.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

the utility model provides an auxiliary lifting device for cubic heat transfer core, includes the hoist body of cuboid form, has seted up lewis hole and several bolt hole on the lateral wall of hoist body in proper order, and the bottom of hoist body is triangle-shaped inclined plane, the shape on inclined plane and the lateral wall shape looks adaptation of treating handling cubic heat transfer core, and U type groove has been seted up along its length direction in the bottom center of hoist body.

Preferably, the depth of the U-shaped groove is greater than the height of the raised lug plate on the side wall of the heat exchange core, and the opening width of the U-shaped groove is slightly greater than the thickness of the raised lug plate.

Preferably, the inner wall of the U-shaped groove is stuck with an anti-collision pad.

The using method of the utility model comprises the following steps:

with the bottom of hoist body towards cubic heat transfer core, make protruding otic placode dress card in U type groove, the inclined plane is laminated mutually with the lateral wall of heat transfer core, installs the bolt in the bolt hole, makes the bottom of bolt and the surface of protruding otic placode inconsistent, binds the rope in the lewis hole again. After a plurality of the hoisting devices are assembled at the hoisting points of the heat exchange core body, a crane is controlled to hoist the heat exchange core body to a specified position.

The utility model has the beneficial effects that:

1. according to the utility model, the U-shaped groove is formed at the bottom of the hanger body and is used for clamping the raised ear plates of the heat exchange core body, so that the raised ear plates are prevented from being damaged due to rope binding in the process of transferring the heat exchange core body, and the use effect of a product is not influenced;

2. according to the utility model, the bottom of the lifting appliance body is designed into the triangular inclined plane matched with the outer wall of the heat exchange core body, when the heat exchange core body is lifted, the inclined plane is fully contacted with the outer wall of the heat exchange core body, the lifting stress surface is enlarged, the safety and stability of the lifting process are ensured, and the heat exchange core body is prevented from sliding down;

3. the lifting device is simple in structure and convenient to use, and the lifting reliability of the heat exchange core body is guaranteed.
