Description
Technical field
The utility model relates to a kind of mining equipment, relates in particular to a kind of bearing pin and steady pin extractor.
Background technology
In the industrial machinery production equipment, reductor is the most general a kind of, and it is undertaking link important in the equipment operation; General reductor relatively more commonly used has cylindrical gear reducer and planet gear type reductor, and their external form is heavier, and internal structure is fairly simple; Main inner gears engaged, gear be the general bearing pin that be unable to do without in mosaic process, in maintenance process, takes out relatively difficulty to bearing pin; The decelerator special tool for service also do not occur on the market now, conventional removing method is that two people use sledgehammer to beat, and more loaded down with trivial details effort works together; And also can train off crookedly sometimes, cause damage for other accessory.
Summary of the invention
The purpose of the utility model provides a kind of bearing pin simple in structure, easy to use and steady pin extractor.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of bearing pin and steady pin extractor comprise handle, and handle one side is fixedly connected with the shelves circle; Shelves circle opposite side is fixedly connected with slide bar; Slide bar, shelves circle and handle are structure as a whole, and the diameter of section of slide bar is less than the diameter of section of shelves circle, and it is characterized in that: the other end of slide bar has the groove that is threaded; The outside opening of the groove that is threaded has internal thread in the groove that is threaded.
According to described bearing pin and steady pin extractor, it is characterized in that: the other end of said slide bar is fixedly connected with connecting rod, and the other end of connecting rod has the said groove that is threaded.
According to described bearing pin and steady pin extractor, it is characterized in that: the said groove internal thread that is threaded is connected with hangs pin, hangs pin and includes write off portion and connecting portion, and write off portion and connecting portion all have external screw thread, and connecting portion is connected with the said groove that is threaded.
According to described bearing pin and steady pin extractor, it is characterized in that: be installed with the sliding hammer top that draws on the said slide bar, sliding to draw the hammer top be the pipe shape, and sliding hammer top and the slide bar of drawing is the annexation that horizontally slips.
The utility model can alleviate the working strength of workmen when the maintenance decelerator, increases work efficiency, and lightly is easy to carry about with one, and profile simply is convenient to dismounting, and a people just can finish the work, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, hangs pin; 2, the groove that is threaded; 3, connecting rod; 4, slide bar; 5, the sliding hammer top that draws; 6, shelves circle; 7, handle.
11, write off portion; 12, connecting portion.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of bearing pin and steady pin extractor, as shown in Figure 1, comprise handle 7; Handle 7 one sides are fixedly connected with shelves circle 6, and shelves circle 6 opposite sides are fixedly connected with slide bar 4, and slide bar 4, shelves circle 6 and handle 7 are structure as a whole; The diameter of section of slide bar 4 is less than the diameter of section of shelves circle 6; The other end of slide bar 4 has the groove 2 that is threaded, and the groove 2 outside openings that are threaded have internal thread in the groove 2 that is threaded.The other end of said slide bar 4 is fixedly connected with connecting rod 3, and the other end of connecting rod 3 has the said groove that is threaded.Said groove 2 internal threads that are threaded are connected with hangs pin 1, hangs pin 1 and includes write off portion 11 and connecting portion 12, and write off portion 11 all has external screw thread with connecting portion 12, and connecting portion 12 is connected with the said groove 2 that is threaded.Be installed with the sliding hammer top 5 that draws on the said slide bar 4, the sliding hammer top 5 that draws is the pipe shape, and the sliding hammer top 5 that draws is the annexation that horizontally slips with slide bar 4.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
The utility model is a kind of mining machinery, is the special tool for service of decelerator, the steady pin of equipment.
The steady pin that this device can also be used for machinery, electric equipment takes out, and will hang pin and take down, and makes the groove that is threaded of this device of external screw thread connection of steady pin just can steady pin be taken out easy to use, high efficiency.
The main feature of the utility model is following:
