Abstract
The utility model relates to a gas turbine transition rear supporting screw dismounting tool, which mainly solves the problem of wasting time and labor and safety hazard when disassembling changeover portion and magnet ring fixing screw of the existing tools. The utility model is characterized in that a body 1 is provided with two angles A, B which are bended upwards, and a collect head 5 which is plumbed with the body 1 is connected with the ends of the two angles; one end of the body 1 is provided with a cubic counterbore 2 at the tail end, and a cubic body 3 which is vertically fixed on a spanner rod sleeve 4 is clamped in the counterbore 2. The gas turbine transition rear supporting screw dismounting tool has characteristics of saving time and labor, safety and reliability.
Description
Technical field:
The utility model supports the screw extracting tool after relating to gas turbine field used extracting tool, especially combustion turbine transitory section.
Background technology:
Along with the development of society, the increase of power consumption, the normal operation of generator is more and more important, gas turbine especially, in order to guarantee normal power generation, gas turbine gets periodic inspection.And in the gas turbine maintenance, when dismounting changeover portion and magnet ring fixed screw, because fixed screw is positioned at compressor exhaust casing tail side, can be very narrow and small for the space of dismounting screw, be that the people can see and just can't stretch out one's hand dismounting, waste time and energy so dismantle this place's screw with conventional instrument, removal efficiency is low.And in the gas nozzle that screw is as easy as rolling off a log when dismounting below falling into, will bring potential safety hazard to generator like this, influence normal power generation.
The utility model content:
In order to overcome the deficiency that wastes time and energy when existing instrument is dismantled changeover portion and magnet ring fixed screw and have potential safety hazard.The utility model supports the screw extracting tool after a kind of combustion turbine transitory section is provided, and this extracting tool has time saving and energy saving and safe and reliable characteristics.
The technical solution of the utility model is: supporting screw extracting tool comprises main body and collet head behind this combustion turbine transitory section, and main body has upwards crooked two angles and its termination to be connected with the collet head vertical with main body; Main body one end afterbody has cubic counterbore, is covered with in the counterbore to be vertically fixed on tommy bar and to put tetragonal body.
Two above-mentioned angles are respectively 160 °-170 ° and 120 °-130 °, and two angle the bests are respectively 165 ° and 125 °.
The beneficial effect that the utlity model has is: because the main body of supporting screw extracting tool has two angles that are bent upwards behind combustion turbine transitory section, match with changeover portion, can in narrow space, rotate, and extend to outside the changeover portion, and be connected with tommy bar cover by cubic counterbore and front end is fixed with collet head at its afterbody, so just solved in dismounting is wasted time and energy during fixed screw and removal efficiency is low problem, reduced labor strength, and screw can be taken out by collet head, prevented that screw from falling in the gas nozzle, cause potential safety hazard, guaranteed that generator normally moves, and simple in structure.
Description of drawings:
Accompanying drawing 1 is the utility model structure cutaway view.
1-main body among the figure, the 2-counterbore, 3-pulls pipe, 4-tommy bar cover, 5-collet head, A-angle of bend, B-angle of bend.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, supporting screw extracting tool comprises main body 1 and collet head 5 behind this combustion turbine transitory section, main body 1 one end afterbodys have cubic counterbore 2, be covered with in the counterbore 2 and be vertically fixed on tetragonal body 3 on the tommy bar cover 4, when the dismounting screw, extend to outside the changeover portion by main body 1, boosting-rod can be inserted and pull reinforcing in the pipe 3, thereby reduced labor strength, saved the time, improved removal efficiency; Main body 1 has two upwards crooked angle (A, B) and its termination be connected with the collet head 5 vertical with main body 1, two angle (A, B) be respectively 165 ° and 125 °,, and extend to outside the changeover portion because of the angle of two 165 ° and 125 ° on the main body 1 is that angle with changeover portion matches, so this instrument can rotate, and the screw after the dismounting can take out by the collet head 5 by this instrument, eliminate potential safety hazard, guaranteed the normal operation of generator.
