Abstract
The utility model relates to a horizontal main valve dismounting device, including the connecting rod to reach strengthening rib and fixed plate through connecting rod interconnect, be equipped with the through -hole that is used for the bolt to wear to establish on the fixed plate, the fixed plate passes through bolt fastening back on main valve, dismantles main valve through the pulling strengthening rib. Compared with the prior art, the utility model discloses be equipped with the through -hole that is used for the bolt to wear to establish on the fixed plate to be connected with main valve through the bolt and fix, and then dismantle main valve get off through the mode of pulling strengthening rib, be fit for the various difficult body that disintegrate, need not prize main valve simultaneously, do not hinder the faying face.
Description
Technical field
The utility model relates to a kind of electric power overhaul field, especially relates to a kind of horizontal main inlet throttle-stop valve provision for disengagement.
Background technology
Steam turbine is the rotary power machinery energy of steam being changed into mechanical power, main inlet throttle-stop valve is contained in the high-pressure admission side of steam turbine, for controlling unlatching or the closedown of steam turbine admission, because the running environment of steam turbine is various, some steam turbines even run on very harsh environment, such as geothermal steam turbine, because geothermal vapour exists the mineral matter of a large amount of easily fouling, if fouling is at main inlet throttle-stop valve place, easily causes main inlet throttle-stop valve bite, and then there is potential safety hazard.
Except these steam turbines, also some steam turbine operations are had in reasonable environment, the repair rate of these steam turbines is lower, therefore easily run for a long time, but because equipment longtime running causes the situation that in disintegration process, doorway faying face not easily disassembles to occur, it is that chi mouth plucking causes that reason is roughly divided into two kinds: one; Two is that bolt is crooked in various degree causes.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of horizontal main inlet throttle-stop valve provision for disengagement is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of horizontal main inlet throttle-stop valve provision for disengagement, comprises connecting rod, and by the interconnective reinforcement of connecting rod and fixed head, described fixed head is provided with the through hole worn for bolt;
Described fixed head is secured by bolts in after on main inlet throttle-stop valve, is dismantled by main inlet throttle-stop valve by pulling reinforcement.
Described connecting rod is provided with two altogether, and is arranged at fixed head both sides respectively.
Described fixed head is circular, and centre is provided with the accommodation hole for holding main inlet throttle-stop valve rotating shaft.
Through hole on described fixed head is provided with 8 altogether.
Described provision for disengagement also comprises interconnective grasping mechanism and haulage gear, and described reinforcement is provided with the holding section coordinated with grasping mechanism, described grasping mechanism is connected with reinforcement, and engaged with reinforcement by described holding section, and under the traction of haulage gear, drive fixed head dismounting main inlet throttle-stop valve.
Described grasping mechanism is made up of multiple gripper.
Connected by connecting axle between described grasping mechanism and haulage gear.
Described fixed head, connecting rod and reinforcement successively between connected mode for welding.
Compared with prior art, the utility model has the following advantages:
1) fixed head is provided with the through hole worn for bolt, and be connected and fixed by bolt and main inlet throttle-stop valve, and then by pulling the mode of reinforcement to be disassembled by main inlet throttle-stop valve, be applicable to the door body of various difficulty of disintegrating, do not need to prize main inlet throttle-stop valve simultaneously, do not hinder faying face.
2) connecting rod is provided with two altogether, and is arranged at fixed head both sides respectively, connects more firm.
3) fixed head is circular, and centre is provided with the accommodation hole for holding main inlet throttle-stop valve rotating shaft, can be fixed on main inlet throttle-stop valve by fixed head easily.
4) because the quantity of the bolt hole on all kinds of main inlet throttle-stop valve may be variant, the through hole on fixed head is provided with 8 altogether, applied widely.
5) bonding strength of grasping mechanism and reinforcement can be improved in holding section, not easily departs from, and decreases security incident.
6) connected by connecting axle between grasping mechanism and haulage gear, instead of adopt rope to connect, draw-gear power can be avoided excessive and accident that grasping mechanism resilience that is that cause leads to.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, fixed head, 2, connecting rod, 3, reinforcement, 11, through hole, 12, accommodation hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of horizontal main inlet throttle-stop valve provision for disengagement, as shown in Figure 1, comprise connecting rod 2, and by the interconnective reinforcement 3 of connecting rod 2 and fixed head 1, fixed head 1 is provided with the through hole 11 worn for bolt, fixed head 1, connecting rod 2 and reinforcement 3 successively between connected mode for welding; Fixed head 1 is secured by bolts in after on main inlet throttle-stop valve, is dismantled by main inlet throttle-stop valve by pulling reinforcement 3.Fixed head is provided with the through hole worn for bolt, and is connected and fixed by bolt and main inlet throttle-stop valve, and then by pulling the mode of reinforcement to be disassembled by main inlet throttle-stop valve, being applicable to the door body of various difficulty of disintegrating, not needing to prize main inlet throttle-stop valve simultaneously, do not hinder faying face.
Connecting rod 2 is provided with two altogether, and is arranged at fixed head 1 both sides respectively, connects more firm.
Fixed head 1 is in circular, and centre is provided with the accommodation hole 12 for holding main inlet throttle-stop valve rotating shaft.Because main inlet throttle-stop valve spindle central is often provided with bolt hole, be applicable to the fixing of fixed head 1, fixed head 1 can be fixed on main inlet throttle-stop valve by middle accommodation hole easily.During concrete operations, first the Bolt dismantling in bolt hole can be got off, then fixed head 1 is fixed on and be placed on main inlet throttle-stop valve, then bolt is fixed in bolt hole through through hole 11, just achieve the process be fixed on by fixed head 1 on main inlet throttle-stop valve.
Through hole 11 on fixed head 1 is provided with 8 altogether.
Provision for disengagement also comprises interconnective grasping mechanism and haulage gear, and reinforcement 3 is provided with the holding section coordinated with grasping mechanism, grasping mechanism is connected with reinforcement 3, and is engaged with reinforcement 3 by holding section, and under the traction of haulage gear, drive fixed head 1 to dismantle main inlet throttle-stop valve.Grasping mechanism can be made up of multiple gripper.
Connected by connecting axle between grasping mechanism and haulage gear, instead of adopt rope to connect, draw-gear power can be avoided excessive and accident that grasping mechanism resilience that is that cause leads to.
