Description
Technical field
The present invention relates to a kind of mining equipment, relate 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 this invention is to provide 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 present invention 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 present invention 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 a structural representation of the present invention.
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 present invention 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 preferred implementation of the present invention; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design concept of the present invention, common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention; The technology contents that the present invention asks for protection all is documented in claims.
The present invention 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.
Main feature of the present invention is following:
1, lightly is easy to carry.
2, can change extractor according to the centre bore internal thread size of bearing pin and hang pin.
3, can change sliding size of drawing the hammer top according to the size of bearing pin.
Development cost of the present invention is low, although simple in structure, easy processing can be taken out bearing pin and steady pin very accurately, changes people construction into by present two people construction, has practiced thrift the labour greatly.
When 4, getting steady pin, remove and hang pin, utilize the external screw thread of steady pin to connect this device and get final product, easy to use, the efficient height.
Use of the present invention is following:
1, take out the reduction box bearing pin:
At first be placed on the sliding hammer top that draws on the slide bar; Being connected, hanging the other end of selling to the extension pin of this extractor and the internal thread of bearing pin centre bore again is connected with slide bar (or connecting rod); Hold handle, left hand sliding hammer top firmly to shelves circle place bump with the right hand then, bearing pin can take out from gear in each bump gradually.
2, take out steady pin:
At first be placed on the sliding hammer top that draws on the slide bar; To hang pin takes down; Be threaded on the external screw thread that makes steady pin and the slide bar (or connecting rod) groove internal thread be connected; The right hand is held handle then, left hand sliding hammer top firmly goes out bump to the shelves circle, and steady pin can take out from gear in each bump gradually.
Hang the internal thread diameter of the external thread diameter on the pin and the groove that is threaded among the present invention and can make different sizes, with bearing pin and the steady pin that takes out different size.
