Description

A kind of HP Raymond bowl mill grinding roller gudgeon dismantling device
Technical field
This practicality newly relates to Roller of Coal Grinder maintenance tool, specifically HP Raymond bowl mill grinding roller gudgeon dismantling device.
Background technology
HP Raymond bowl mill is vertical middle-speed coal-grinding machine, the grinding roller arranged by three horizontal symmetrical is milled coal dust, a gudgeon is respectively used in the both sides of grinding roller support, grinding roller support is fixed on coal pulverizer shell, by bolt-connection, gudgeon flange is fastened on coal pulverizer shell, during coal pulverizer overhaul, needs demolition, installation gudgeon.Gudgeon itself is without the top wire hole of traditional design, and demolition, installation difficulty, consumes more manpower and time.
Summary of the invention
The utility model is the problem solving HP Raymond bowl mill grinding roller gudgeon dismounting inconvenience, provides a kind of specific purpose tool, facilitates dismounting and the installation of gudgeon.Concrete scheme is: a kind of HP Raymond bowl mill grinding roller gudgeon dismantling device, comprise limiting bracket, pull bar, pull-rod nut and a hollow jack, wherein, limiting bracket is the support that several small screws and a spacing flange are fixed into, the parallel flange of described spacing flange and Roller of Coal Grinder gudgeon is arranged, several small screw one end are separately fixed on spacing flange, the other end be each passed through the flange hole of gudgeon flange and coal pulverizer shell affixed; Described pull bar is each passed through the centre bore of spacing flange and gudgeon, and a pull-rod nut is fixed at two ends respectively; Described hollow jack is arranged on described pull bar, is loaded between pull-rod nut and spacing flange during dismounting gudgeon, and jacking back stay and pull-rod nut coordinate tractive to go out gudgeon; Installing gudgeon fashionable dress between pull-rod nut and gudgeon, is that fulcrum pushes gudgeon with pull-rod nut after jacking.
Advantage: the utility model can quick-detachment, HP Roller of Coal Grinder gudgeon is installed, simplify folding dress operation greatly, save artificial.This dismantling device low cost of manufacture, easy and simple to handle, reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model dismounting gudgeon;
Stereogram when Fig. 2 is the utility model dismounting gudgeon;
Fig. 3 is the structural representation that the utility model installs gudgeon.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is illustrated:
A kind of HP Raymond bowl mill grinding roller gudgeon dismantling device, comprise limiting bracket, pull bar 1, pull-rod nut 8 and a hollow jack 2, wherein, limiting bracket is the support that several small screws 4 and a spacing flange 3 are fixed into, described spacing flange 3 be arranged in parallel with the flange 5 of Roller of Coal Grinder gudgeon, several small screw 4 one end are separately fixed on spacing flange 3, the other end be each passed through the flange hole of gudgeon flange 5 and coal pulverizer shell 6 affixed; Described pull bar 1 is each passed through the centre bore of spacing flange 3 and gudgeon flange 5, and a pull-rod nut 8 is fixed at two ends respectively; Described hollow jack 2 is arranged on described pull bar 1, and be loaded between pull-rod nut 8 and spacing flange 3 during dismounting gudgeon, jacking back stay 1 and pull-rod nut 8 coordinate tractive to go out gudgeon 5; Gudgeon fashionable dress is installed between pull-rod nut 8 and gudgeon flange 5, after jacking with pull-rod nut 8 for fulcrum pushes gudgeon 5.
The parts that the utility model comprises combine respectively for dismantling or install in the process of gudgeon, and concrete using method is:
As shown in Figure 1, 2, gudgeon is dismantled:
Relate to parts: 1, spacing flange and small screw; 2, pull bar; 3, pull-rod nut; 4, hollow jack.Annex: the primary nut that small screw quantity is 2 times.
(1) select the uniform flange hole in position on gudgeon flange 5, some small screws 4 are screwed in through flange hole in the screw on coal pulverizer shell 6 also fixing; Small screw 4 other end first screws in a nut respectively, loads a spacing flange 3, screws in a nut respectively again outside spacing flange 3; Adjust each nut location of spacing flange 3 both sides and ensure that spacing flange 3 is parallel with gudgeon flange 5, clamp nut also fixes spacing flange 3, and limiting bracket like this installs.
(2) by pull bar 1 can be a large screw rod, it is passed the centre bore of spacing flange 3 and gudgeon, a pull-rod nut 8 is installed in termination; Be inserted in from pull bar 1 other end by hollow jack 2, outside is installed a pull-rod nut 8 again and is screwed.
(3) jack, gudgeon is drawn out gradually.
As shown in Figure 3, gudgeon is installed:
Relate to parts: 1, pull bar; 2, pull-rod nut; 3, hollow jack.
(1) gudgeon of grinding roller support 7 both sides is placed in installation front position;
(2) with a suitable long large screw rod of double end, namely pull bar 1 is through installation side gudgeon centre bore until pass from grinding roller support 7 opposite side gudgeon 5 ' and coal pulverizer shell 6 ' center, and a pull-rod nut 8 is installed in termination.
(3) be inserted in from pull bar 1 other end by hollow jack 2, outside is installed a pull-rod nut 8 again and is screwed.
(4) gudgeon is headed into coal pulverizer by jacking hollow jack 2 gradually, until two gudgeon installation sites.
The utility model can quick-detachment, HP Roller of Coal Grinder gudgeon is installed, simplify folding dress operation greatly, save artificial.This dismantling device low cost of manufacture, easy and simple to handle, reliability is high, does not destroy gudgeon body.
