Description
Technical field
The utility model belongs to mechanical equipment technical field, more particularly, to a kind of mandrel for the cold dismounting of scraper winch
Fixing device.
Background technology
Scraper winch is a kind of common ore handbarrow of underground mine.Scraper winch often goes out in use
Tripod mandrel in existing major-minor reel loosens, so as to cause sun gear, planetary gear, bearing damage.Tripod mandrel at present
Fixed form, which is, is fixed using the pressing plate of mandrel one end, the long side of pressing plate lower part is closely against the plane that mandrel ties position
On, mandrel is fixed.
Defect existing in the prior art is：During the scraping of ore, since the granularity of ore is big, be hit change
Greatly, load change is also big, although the axial float of mandrel is not destroyed, pressing plate operates abrasion for a long time with mandrel,
Gradually cause central axis.Mandrel will be such that axis, hole wears at the same time once rotating, aperture increases, produce planetary gear very big
Circular runout, can make mandrel, A-frame fracture when serious.Due to frictional heating, it can also be plastically deformed bearing, gear point
Erosion, gluing, break of gear tooth, Rabble mine winch locking, damage motor deceleration case and parts；It can also produce very big shake at the same time
Dynamic, noise.
The content of the invention
The purpose of this utility model be to provide it is a kind of simple in structure, it is easy for installation, can effectively prevent mandrel and pressing plate phase
Mutually denude and cause central axis, extend the service life of sun gear, planetary gear and bearing in scraper winch, when shortening maintenance
Between, the fixer for mandrel for the cold dismounting of scraper winch of reduction material and spare parts consumption.
The purpose of this utility model is realized by following technical proposals：
The fixer for mandrel for the cold dismounting of scraper winch of the utility model, including tripod, are set in this triangle
Two fixing bolts on frame top, it is characterised in that mandrel fixed pin is equipped with a fixing bolt, it is solid at described two
Determine to be connected with fixed steel wire between bolt, the mandrel fixed pin includes fixing end and straight pin, and the fixed end cap is connected on
On one fixing bolt, the straight pin is inserted in the termination tapping of mandrel.
The fixing end of the mandrel fixed pin is square fixed end, and the center of this square fixed end is equipped with and the fixation
The centre bore that bolt matches, the fixing bolt are arranged in the centre bore.
The advantages of the utility model：
The fixer for mandrel for the cold dismounting of scraper winch of the utility model changes pressing plate fixed mode, can be effective
Prevent central axis, be readily disassembled, eliminate heat dismounting center roller and bearing damages, extend sun gear in scraper winch, OK
The service life of star-wheel and bearing, shortens the repair time, reduces the consumption of material and spare part；In addition, use the utility model
Fixing device, during dismounting, as long as twisting off fixing bolt, is dismantled without electrogas welding.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the left view of the utility model Fig. 1.
Fig. 3 is the structure diagram of the utility model mandrel fixed pin.
Embodiment
Specific embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1,2 and 3, the fixer for mandrel for the cold dismounting of scraper winch of the utility model, including triangle
Frame 1, sets two fixing bolts 3 on 1 top of this tripod, it is characterised in that consolidate on a fixing bolt 3 equipped with mandrel
Rationed marketing 4, is connected with fixed steel wire 5 between two fixing bolts 3, the mandrel fixed pin 4 include fixing end 4-1 and
Straight pin 4-2, the fixing end 4-1 are socketed on a fixing bolt 3, and the straight pin 4-2 is inserted in mandrel 2
Termination tapping.
The fixing end 4-1 of the mandrel fixed pin 4 is square fixed end, the center of this square fixed end be equipped with it is described
The centre bore that fixing bolt 3 matches, the fixing bolt 3 are arranged in the centre bore.
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1,2 and 3：With 45#The mandrel that steel processing and fabricating is made of one fixing end 4-1 and straight pin 4-2 is consolidated
Rationed marketing 4.Fixing end 4-1 is with centre bore, for through fixing bolt 3, with stationary spindle 2, the diameter of the centre bore to be according to solid
The model for determining bolt 3 determines that the thickness of fixing end 4-1 is generally 4-7mm.If 2 a diameter of d of mandrel, straight pin 4-2's
Diameter is about 1/4 of d or so.Such as scraper winch mandrel diameters are 45mm, then straight pin diameter is about 10mm.
It is tight with straight pin 4-2 slightly larger than the diameter of straight pin 4-2 in 2 termination fixed position drilling of mandrel, the bore dia
Close fit, and ensure that straight pin 4-2 can be by the drilling；During stationary spindle 2, ready-made straight pin 4-2 insertions mandrel 2 is fixed
In the drilling at end, straight pin 4-2 is fixed on tripod 1 with fixing bolt 3, recycles thin fixation steel wire 5 will after fixed
Two fixing bolts 3 are fixed, and prevent the revolution of fixing bolt 3 from loosening；During dismounting, as long as dismounting fixing bolt 3.
The fixer for mandrel for the cold dismounting of scraper winch of the utility model changes pressing plate fixed mode, can be effective
Prevent mandrel 2 from rotating, be readily disassembled, eliminate heat dismounting center roller 2 and bearing damage, extend sun gear in scraper winch,
The service life of planetary gear and bearing, shortens the repair time, reduces the consumption of material and spare part；In addition, use the utility model
Fixing device, during dismounting, as long as twisting off fixing bolt 3, dismantled without electrogas welding.
