Abstract
The utility model relates to a hydraulic generator break pin instrument of choosing, including thread brace rod, sleeve pipe, nut, the shaping of thread brace rod hypomere have with the break pin in the middle of internal thread hole matched with screw thread, the upper segment shaping has the screw thread with nut matched with, the drum of sleeve pipe for taking the bottom plate, the internal diameter of drum is greater than the external diameter of break pin, the hole that thread brace rod passed and be less than the nut bore is offered up a sacrifice to the bottom plate. The utility model discloses a hydraulic generator break pin instrument of choosing simple structure, convenient to use has effectually reduced the intensity of labour that the break pin was extracted, and it is high to have improved work efficiency.
Description
Technical field
The utility model relates to a kind of instrument pulling out break pin, particularly relates to a kind of hydrogenerator break pin drawer.
Background technology
Break pin is a kind of safety guard on hydrogenerator, and under ordinary loading conditions, break pin normally works, transmitting forces, and when there is unexpected jam, break pin is stressed exceedes setting value, and break pin ruptures, and avoids causing more havoc.Post-rift break pin is stuck in the installing hole of workpiece due to the reason such as stress deformation and corrosion, compares and expends time in and muscle power, affect the replacing speed of break pin when using common instrument to be taken out.
Summary of the invention
The utility model is exactly to solve the problem, and provides a kind of structure simple, and operation is convenient, can extract the specific purpose tool of hydrogenerator break pin faster.
The purpose of this utility model is achieved in that hydrogenerator break pin drawer, comprise thread, sleeve pipe, nut, described thread hypomere forms the screw thread matched with internal thread hole in the middle of break pin, and epimere forms the screw thread matched with nut; Described sleeve pipe is the cylinder of band base plate, and the internal diameter of described cylinder is greater than the external diameter of break pin, described base plate passes for thread and is less than the hole of nut bore.
Further, described thread epimere end symmetric forms the spanner card-tight part of plane.
Further, described thread hypomere bore is less than thread epimere bore.
Further, be lined with pad between described nut and cover tube bottom plate, be convenient to make uniform force.
Hydrogenerator break pin drawer structure of the present utility model is simple, easy to use, effectively reduces the labour intensity that break pin is extracted, improves operating efficiency high.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is result of use figure of the present utility model;
Fig. 2 is exploded view of the present utility model.
Legend: 1. workpiece, 2. break pin, 3. thread, 31. thread hypomeres, 32. thread epimeres, 33. spanner card-tight part, 4. sleeve pipes, 41. holes, 42. base plates, 5. pad, 6. nut.
Detailed description of the invention: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 2, hydrogenerator break pin drawer, comprise thread 3, sleeve pipe 4, nut 6, thread hypomere 31 forms the screw thread matched in internal thread hole middle with break pin 2, epimere 32 forms the screw thread matched with nut 6, thread epimere 32 end symmetric forms the spanner card-tight part 33 of plane, and thread hypomere 31 bore is less than thread epimere 32 bore; Sleeve pipe 4 is the cylinder of band base plate 42, and the internal diameter of cylinder is greater than the external diameter of break pin 2, base plate 42 passes for thread 3 and is less than the hole 41 of nut 6 bore, being lined with pad 5 between nut 6 and cover tube bottom plate 42.
Operation principle of the present utility model is as follows, as shown in Figure 1, before break pin 2 is installed, first by hole forming internal thread in existing break pin 2, when in the installing hole that break pin 2 breaks at workpiece 1, in order to break pin 2 is extracted, first thread hypomere 31 is screwed in the middle internal thread hole of break pin 2 to be pulled out, sleeve pipe 4 is buckled on the outer surface of workpiece 1 through thread 3, again pad 5 is placed on the base plate 42 of sleeve pipe 4 through thread 3, nut 6 is screwed in thread epimere 32 and compress gasket 5, spanner is used constantly to be screwed by nut 6, in the process that nut 6 constantly screws, thread hypomere 31 is constantly pulled out, break pin 2 is taken away gradually the installing hole of workpiece 1 simultaneously, continue rotating nut 6 until break pin 2 is extracted completely.In use, for preventing thread 3 from rotating together with nut 6, spanner can be used to block the spanner card-tight part 33 of thread 3.
Claims (4)
1. a hydrogenerator break pin drawer, comprises thread, sleeve pipe, nut, it is characterized in that: described thread hypomere forms the screw thread matched with internal thread hole in the middle of break pin, and epimere forms the screw thread matched with nut; Described sleeve pipe is the cylinder of band base plate, and the internal diameter of described cylinder is greater than the external diameter of break pin, described base plate passes for thread and is less than the hole of nut bore.
