The tool can reduce the number of workers and labor intensity, quicken the working progress and reduce the overhaul period.
Description
Technical Field
The utility model relates to the field of large hydroelectric generating set overhauling equipment, in particular to a special tool for turning a large hydroelectric generating set.
Background
When the large hydroelectric generating set is manually turned, the rotating part of the large hydroelectric generating set needs to be pulled to rotate, and the manual turning is difficult or even impossible when no good acting point exists. The maintenance of the water supply motor set is difficult greatly, so that the maintenance work can not be carried out normally.
The existing barring mode of the large hydroelectric generating set is to increase or decrease the number of overhaul people, and 30-50 people are uniformly distributed at the magnetic pole under the rotor to drive the rotating part to rotate together by force.
The large hydroelectric generating set has a series of problems of difficult barring, more required number of people, difficult unified coordination, high safety risk and the like.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a special turning tool for a large hydroelectric generating set, which reduces the number of workers and labor intensity, accelerates the working progress and reduces the overhaul period.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a large-scale hydro-power generating unit barring specialized tool, is including being arranged in hanging the connecting piece of establishing in the peripheral preformed hole of rotor, and the connecting piece includes the front end couple, and the front end couple is connected with the rear end link through the atress pole, connects the rope and is connected with the rear end link through turning to the subassembly, connects the rope other end and is equipped with the couple.
In the preferred scheme, the steering assembly is a chain block, a hook at the upper end of the chain block is hung on a hanging ring at the rear end, and a lifting hook of the chain block is connected with the connecting rope.
In the preferred scheme, the steering assembly comprises a support, a connecting hook is arranged on the support, a steering wheel is arranged on the support, and a traction rope is connected with the connecting rope after bypassing the steering wheel.
In a preferable scheme, a pulling ring is arranged at the end part of the pulling rope.
According to the tool special for barring of the large hydroelectric generating set, the distance between the steering assembly and the lower rack support arm is shortened by pulling the pulling rope or the chain of the chain block, so that the rotating assembly of the rotor is pulled to rotate by a certain angle, the hanging position of the front end hook is changed, the rotating assembly of the rotor is continuously rotated by a certain angle, and the rotating barring is sequentially repeated to complete the rotating barring. Through this instrument, only need 1~2 individuals can accomplish the barring, alleviate staff's quantity and intensity of labour for the job schedule reduces the maintenance time limit for a project.
Drawings
The utility model is further illustrated with reference to the accompanying drawings and examples:
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic diagram of a preferred structure of the present invention;
in the figure: the front end couple 1, the stress beam 2, rear end link 3, connect rope 4, couple 5, chain block 6, support 7, connect couple 8, directive wheel 9, tractive rope 10, tractive ring 11, upper end couple 601, lifting hook 602.
Detailed Description
As shown in fig. 1, a large-scale hydro-power generating unit barring specialized tool, including being used for hanging the connecting piece of establishing in the peripheral preformed hole of rotor, the connecting piece includes front end couple 1, and front end couple 1 hangs and establishes in the peripheral preformed hole of rotor, and front end couple 1 is connected with rear end link 3 through stress rod 2, connects rope 4 and is connected with rear end link 3 through turning to the subassembly, connects 4 other ends of rope and is equipped with couple 5, and couple 5 is used for hanging and establishes on the lower frame support arm.
In this embodiment, the steering assembly comprises a support 7, a connecting hook 8 is arranged on the support 7, a steering wheel 9 is arranged on the support 7, and a traction rope 10 is connected with the connecting rope 4 after bypassing the steering wheel 9.
When the turning mechanism is used specifically, the distance between the steering assembly and the lower rack support arm is shortened by pulling the pulling rope 10, so that the rotating assembly of the pulling rotor rotates by a certain angle, the front end hook 1 is adjusted and hung in preformed holes in different positions on the periphery of the rotor, the pulling rope 10 is pulled repeatedly, the rotating assembly of the rotor continues to rotate by a certain angle, and the turning mechanism is repeated in sequence to complete turning. Through this instrument, only need 1~2 individuals can accomplish the barring, alleviate staff's quantity and intensity of labour for the job schedule reduces the maintenance time limit for a project.
Preferably, the end of the pulling rope 10 is provided with a pulling ring 11.
Through setting up tractive ring 11, conveniently pull tractive rope 10.
Preferably, as shown in fig. 2, the steering assembly is a chain block 6, an upper end hook 601 of the chain block 6 is hung on the rear end hanging ring 3, and a hook 602 of the chain block 6 is connected with the connecting rope 4.
Through the chain of pulling chain block 6 to the pulling connection rope 4, thereby the rotating assembly who stimulates the rotor rotates.
The connecting piece of this instrument is through setting up front end couple 1 and atress pole 2, makes things convenient for front end couple 1 to hang and establishes in the preformed hole, moreover through the extension of atress pole 2, convenient and the being connected that turns to the subassembly, prevents the interference in the aspect of the rotor structure and influences the installation that turns to the subassembly. The hanging points are convenient to replace by means of a hook principle, the rotating assembly of the rotor rotates by a certain angle by pulling the pulling rope 10 or the chain of the chain block 6, and the batch-wise rotating jigger is realized by replacing the hanging points, so that the number of workers and the labor intensity are reduced; the safety risk is improved; the working efficiency is improved; the working schedule is accelerated, and the overhaul period is shortened.
