Abstract
The utility model discloses an underneath-installed turning gear device for examination and reparation of a steam turbine, which comprises a box body (1), a motor (2) and a bottom plate (3). The motor (2) is fixedly arranged on the box body (1), the bottom plate (3) is arranged at the middle part of the box body (1), a transmission gear (4) and a coiling gear (5) are arranged in the box body (1), the transmission gear (4) is connected with a motor shaft, the coiling gear (5) is meshed with the transmission gear (4), and the tooth part of the coiling gear (5) stretches out of the lower side part of the box body (1). With simple structure, high examination as well as reparation efficiency, high practicability and high popularization value, the underneath-installed turning gear device can conveniently coil a rotor of the steam turbine to rotate and can also be used as an accident turning gear.
Description
Technical field
The utility model relates to a kind of overhaul of steam turbine down-mounting type barring gear that turbine rotor rotates that is used to coil.
Background technique
During overhaul of steam turbine, need the moving turbine rotor of dish to slowly run, so that carry out the detection of various precision and the dismounting of component.After traditional in the market maintenance jiggering installed fully, the dish moving gear of jiggering can influence freely hanging out of turbine rotor, in the time of rotor need being hung out, needed earlier the animal economy of jiggering to be removed.After rotor hangs in, need the jiggering animal economy is shifted near, make the dish moving gear of jiggering and epitrochanterian gear engagement together, jiggering could be worked then, and this mode overhaul efficiency is low, and the repair time is long.In addition, during the steam turbine proper functioning of power plant, its work jiggering is out of order sometimes, at this moment, needs a kind of accident jiggering to be installed in the position of work jiggering, and the moving rotor rotation of dish is out of shape because of the inequality of being heated in order to prevent turbine rotor.And traditional maintenance jiggering can't be installed when steam turbine covers cylinder cap, can only work after steam turbine is opened cylinder cap, and therefore, this kind jiggering can't serve as the accident jiggering when the work jiggering is out of order.
The model utility content
The purpose of this utility model is to provide a kind of and makes things convenient for that the moving turbine rotor in domain rotates, the overhaul efficiency height, can serve as the overhaul of steam turbine down-mounting type barring gear of accident jiggering.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: overhaul of steam turbine down-mounting type barring gear, the base plate that comprises casing, is fixedly installed in the motor on the casing and is installed in the casing middle part, be provided with driving gear and dish moving gear in the described casing, described driving gear is connected with motor shaft, described dish moving gear is meshed with driving gear, and the tooth portion of dish moving gear stretches out in the lower side of casing.
Be provided with position regulating device between described casing and the base plate.
Be provided with clutch between described motor shaft and the driving gear.
Described base plate is provided with mounting hole, is used for passing through Bolt Connection with the tapped hole of the position of installment work jiggering.
Owing to adopted above-mentioned structure, the utility model also can be installed when steam turbine covers cylinder cap, can not open the moving rotor rotation of situation lower wall of cylinder cap at steam turbine, when the work jiggering is out of order, can serve as the accident jiggering and use, prevent from turbine rotor to be out of shape because of the inequality of being heated because of the fault of work jiggering.In addition, do not influence the maintenance of turbine rotor after the utility model is installed, pull the handle of clutch, make motor shaft and driving gear be in non-linkage status, then each gear is not subjected to driven by motor, is in the state that freely rotates.Because the tooth portion of dish moving gear stretches out in the lower side of casing, whole device is fixed in the lower side of turbine rotor during use, turbine rotor promptly can lift (hang in or hang out) freely like this, this device does not have at all influence (after hanging in to it, gear on the turbine rotor promptly with this device in dish moving gear engagement), therefore, this device can be realized disposable installation in the maintenance, dismounting, significantly improve overhaul efficiency, save the repair time.The utility model is simple in structure, has very strong practicability and promotional value.

Embodiment
As shown in Figure 1 to Figure 3, overhaul of steam turbine described in the utility model down-mounting type barring gear, the base plate 3 that comprises casing 1, is fixedly installed in the motor 2 on the casing 1 and is installed in the middle part of casing 1.Be provided with position regulating device 7 between described casing 1 and the base plate 3.After base plate 3 was fixed, controlling device 7 was used to regulate the position of casing 1, and dish moving gear 5 is meshed with turbine rotor gear 10.Be provided with four driving gears 4 and a dish moving gear 5 in the described casing 1, described driving gear 4 is connected with motor shaft, and motor shaft is provided with gear block, and gear block and motor shaft are by key joint, and gear block is used to connect motor shaft and engagement driving gear 4.Be provided with clutch 8 between described motor shaft and the driving gear 4, the position that clutch 8 is used to regulate driving gear 4 makes driving gear 4 and gear block be in the state of engagement or non-engagement.Described dish moving gear 5 is meshed with driving gear 4, and driving gear 4 can be given dish moving gear 5 with the transmission of power of motor 2, and the tooth portion of dish moving gear 5 stretches out in the lower side of casing 1.
Extremely shown in Figure 5 as Fig. 4, during the utility model work, base plate 3 is fixed in the lower side of turbine rotor 9, make the tooth portion of dish tooth portion of moving gear 5 and turbine rotor gear 10 close, re-use controlling device 7 and regulate the position of casing 1, dish moving gear 5 is meshed well with turbine rotor gear 10 get final product.
In a word; though the utility model has been enumerated above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, tongue then all should be included in the protection domain of the present utility model.
