Description

Lifting appliance for integral hoisting tower crane

Technical Field

The utility model belongs to the technical field of the tower machine is supporting, a be used for integral hoisting flat-top tower machine hoist is related to.

Background

In the engineering machinery field, a lot of products all have very big quality and volume, generally all need tear open into a plurality of spare parts and just can carry out the transition, but have some special projects, for example large-scale shipyard, the main equipment of shipbuilding is large-scale portal crane, and the tower machine is as auxiliary assembly, and when shipbuilding, the tower machine needs the frequent shift position, can't shift at every turn and all dismouting tower machines, in order to raise the efficiency, and then just need an integral hoisting device, wholly hoist the tower machine and be used for shifting. The tower crane is large in overall size and tonnage, moving the tower crane is a huge project, and the safety and controllability of integral hoisting need to be considered heavily. The devices which can be used for hoisting the complete machine on the market are rare at present. At present, when a large-scale tower crane is used for shipbuilding operation, the working condition of frequent displacement is met, and the tower crane cannot be frequently disassembled and assembled on a construction site, so that integral hoisting is carried out, and integral displacement is achieved. However, the integral body of the tower crane is large, the structure is complex, the tonnage is large, and the safety and controllability of integral hoisting need to be considered heavily. At present, the common integral hoisting methods of the tower crane mainly comprise the following steps: 1. the lifting device is hoisted by adopting a flexible hoist, lifting lugs are arranged at the positions of the tower crane underframe, the lifting lugs are welded on the ballast underframe, and the large-diameter steel wire rope and the pulley block are utilized for integral hoisting. The method has high requirements on the quality of the welding lifting lug and needs rigorous calculation. Meanwhile, the steel wire ropes are too long, the lengths of 4 steel wire ropes cannot be guaranteed to be uniform, and the condition of unbalance loading can occur. 2. A plurality of cranes are adopted for lifting, two large-scale crawler cranes or truck cranes are arranged on two sides of a balance arm and an arm support of the crane, but the crane is not suitable for a tower crane and can be generally used for gantry crane lifting, the height of a tower body of the tower crane is high, and the lifting consistency of two lifting devices cannot be guaranteed. Therefore, there is a need to provide a reliable and safe spreader for integral hoisting tower cranes to solve the above-mentioned problems in construction.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, reasonable in design can effectively overcome a great deal of not enough of current tower machine integral hoisting method and be used for integral hoisting tower machine hoist.

The utility model adopts the technical proposal that: the lifting appliance comprises a connecting plate and is characterized in that: the two sides of the upper part of the connecting plate are respectively fixed with a lifting hook connecting rod used for being connected with a lifting hook of a lifting device, the lower part of the connecting plate is hinged with the upper ends of four middle connecting rods which are uniformly distributed, the lower ends of the four middle connecting rods are respectively connected with the upper parts of four corners of a supporting square frame, the lower parts of the four corners of the supporting square frame are respectively hinged with the upper ends of four lifting beam connecting rods, and the lower ends of the four lifting beam connecting rods are respectively connected with lifting beams.

Adopt above-mentioned structure, during the use, hoist device will through the lifting hook the utility model discloses hang to tower machine top, whereabouts to the position that hanging beam connecting rod lower extreme can be connected with the hanging beam to be connected hanging beam connecting rod lower extreme and hanging beam, hoist device promotes, removes the integral hoisting that can realize the tower machine. The utility model relates to a special lifting device for integral hoisting tower machine has filled the blank of this type of device, very big satisfied actual demand. Has the following advantages: 1. the utility model discloses wholly adopt succinct rigid structure can satisfy the hoist and mount requirement, effectively reduced flexible wire rope length inequality and leaded to hoist uneven risk, safe and reliable. 2. Can directly pull down after the hoist and mount is accomplished, make things convenient for the frequent aversion of tower machine, and can not harm the tower machine, labour saving and time saving has reduced the human consumption, has improved work efficiency, especially can satisfy the demand of special engineering project to the aversion of tower machine operation again, convenient and practical.
