Technical Field
The utility model belongs to the technical field of guide shoes of vertical water turbines, and particularly relates to a looseness preventing device for a guide shoe gap adjusting bolt of a vertical water turbine.
Background
At present, a plurality of vertical water turbines are installed, the vibration of the water turbine is increased after the gap of the guide shoe is increased, and as the adjusting bolt fixing rod plays a role in limiting the circumference and the radial direction of the guide shoe, the space is narrow, and the locking methods such as permanent locking, cotter pins, locking wires, U-shaped nuts, adhesives, sealing adhesive tape nuts and the like are not applicable, so that the locking gasket has poor effect after being used. If the guide shoe adjusting bolt is loosened, the vibration of the water turbine is increased, so that the safety operation of the equipment is greatly influenced, and if the vibration is large, the shutdown is carried out, so that the normal production of the equipment is influenced.
Disclosure of utility model
Aiming at the problems existing in the prior art, the utility model aims to provide a looseness-preventing device for a guide shoe clearance adjusting bolt of a vertical water turbine.
The above object is achieved by the following technical scheme:
A kind of locking device of gap adjusting bolt used for guide shoe of vertical water turbine, its composition includes: the device comprises a bearing seat and a guide shoe, wherein a gap adjuster is fixed between the bearing seat and the guide shoe, a positioning sleeve is sleeved on the gap adjuster to sleeve the gap adjuster on a large fixing nut and a small fixing nut, a fixing plate is fixed on the positioning sleeve, and the fixing plate is fixed with the bearing seat through a bolt.
The anti-loosening device for the guide shoe gap adjusting bolt of the vertical water turbine is characterized in that the positioning sleeve is a cylindrical sleeve, a large hexagonal hole and a small hexagonal hole are formed in the positioning sleeve, two large adjusting bolts are connected to the positioning sleeve at the large hexagonal hole in a threaded mode, and two small adjusting bolts are connected to the positioning sleeve at the small hexagonal hole in a threaded mode.
The fixing plate is an L-shaped plate.
Advantageous effects
1. According to the hydraulic turbine guide shoe fixing device, the positioning sleeve and the adjusting bolt are combined, the inner diameters of the large hexagonal hole and the small hexagonal hole of the positioning sleeve are matched with the large fixing nut and the small fixing nut of the two hydraulic turbine guide shoes to be fixed, the large fixing nut and the small fixing nut which are fastened are fixed through the large adjusting bolt and the small adjusting bolt, and then the fixing plate is fixed on the hydraulic turbine bearing seat through the bolts.

In the figure: 1. a bearing seat; 2. a guide shoe; 3. a gap adjuster; 4. a positioning sleeve; 5. a fixing plate; 6. a small adjusting bolt; 7. a large adjusting bolt; 31. a screw sleeve; 32. a large fixing nut; 33. a small screw; 34. a small fixing nut; 41. a large hexagonal hole; 42. small hexagonal holes.
Detailed Description
A kind of locking device of gap adjusting bolt used for guide shoe of vertical water turbine, its composition includes: the bearing seat 1 and the guide shoe 2 are fixedly provided with a gap adjuster 3, the gap adjuster is sleeved with a positioning sleeve 4 which is sleeved on a large fixing nut 32 and a small fixing nut 34, the positioning sleeve is fixedly provided with a fixing plate 5, and the fixing plate is fixed with the bearing seat through bolts.
The anti-loosening device for the guide shoe gap adjusting bolt of the vertical water turbine is characterized in that the positioning sleeve is a cylindrical sleeve, a large hexagonal hole 41 and a small hexagonal hole 42 are formed in the positioning sleeve, two large adjusting bolts 7 are connected to the positioning sleeve at the large hexagonal hole in a threaded manner, and two small adjusting bolts 6 are connected to the positioning sleeve at the small hexagonal hole in a threaded manner.
The fixing plate is an L-shaped plate.
The gap adjuster includes: the small screw rod is in threaded connection with the threaded sleeve, the large fixing nut is in threaded connection with the threaded sleeve, the small fixing nut is in threaded connection with the small threaded sleeve, the connecting mode is a structural mode of a gap adjuster in the prior art, the small fixing nut is not described in detail, two identical holes are formed in the locating sleeve, the two identical holes are respectively a large hexagonal hole and a small hexagonal hole, the large hexagonal hole is matched with the large fixing nut, the small hexagonal hole is matched with the small fixing nut, the large hexagonal hole is sleeved on the large fixing nut after the locating sleeve is sleeved on the small fixing nut, two large adjusting bolts and two small adjusting bolts are in threaded connection with the locating sleeve, after the locating sleeve is sleeved on the locating sleeve, the end part of the large adjusting bolt is propped against the side face of the large fixing nut, the end part of the small adjusting bolt is propped against the side face of the small fixing nut, the locating sleeve is fixedly provided with a fixing plate which is L-shaped plate, and the fixing plate is connected with the bearing seat through bolts, and the locating sleeve is fixed. The water turbine often has a bigger guide shoe gap in operation, and the main reasons are that the guide shoe adjusting nut and the tightening nut thereof are loosened, so that the locking methods of permanent locking, cotter pins, locking wires, U-shaped nuts, adhesives, sealing adhesive tape nuts and the like are not applicable, and the effect of the stop gasket after use is poor. By adopting the bolt locking device, the installation and the disassembly are convenient, the operation is simple, the vertical hydraulic turbine guide shoe gap adjusting bolt can be conveniently loosened, the guide shoe gap qualification of the hydraulic turbine in long-time operation can be better ensured, the unit operation safety and the effective operation hours are improved, and meanwhile, the labor, the materials and the cost for replacing lubricating oil are reduced.
