Description
Technical field
The utility model relates to provision for disengagement, relates in particular to be used for provision for disengagement that the water distribution dish is disassembled from planetary reduction box.
Background technology
At present, in the coal in China industry, mainly rely on coal-winning machine to carry out the exploitation of coal.
In coal-winning machine, the rocking arm planetary reduction box is installed, and the driving square toes is installed in this rocking arm planetary reduction box inside.
In addition, in order to guarantee that the rocking arm planetary reduction box runs well, be necessary the rocking arm planetary reduction box is lowered the temperature, so also must introduce cooling water from the outside, therefore, the water distribution dish that is connected with the driving square toes by interference fit configuration one at the top of rocking arm planetary reduction box.
Yet rocking arm planetary reduction box water distribution dish is interference fit with driving square toes, and the magnitude of interference is big and connect very fastening.
And industry adopts following method usually when dismounting at present:
First method is that generally speaking, dismounting water distribution dish needs three jackscrews that size is M36, lentamente the water distribution dish is ejected from driving square toes;
Another kind method is that under the rust corrosion serious situation, when first method can't be dismantled, just must disassemble the water distribution dish by the forcing press of 400t this moment.
More than two kinds of methods shortcoming is all arranged:
The time that first method needs is long, and efficiency is lower, and also relatively more serious to the damage of jackscrew;
Second method need be adjusted the frock clamp of forcing press, and is because pressure is bigger, more serious to the damage of faying face in the process of pressing down, and has certain potential safety hazard.
Hence one can see that, and method for dismounting of the prior art exists all that removal efficiency is low, the problem of easy damaged mating surface.
So, be necessary to design a kind of method for dismounting of new rocker arm of coal mining machine planetary reduction box water distribution dish, to overcome above-mentioned various defective.
The utility model content
The utility model is just in view of the problem of above-mentioned existence and put forward, its objective is provides provision for disengagement and uses the method for this provision for disengagement so that rocker arm of coal mining machine planetary reduction box water distribution dish is dismantled, this method for dismounting is compared with method of the prior art, employed instrument is simpler, easily operation.
To achieve these goals, the utility model adopts a kind of provision for disengagement, comprises two saddles and the supporting leg that is installed on the described saddle, and two saddles are parallel opposed each other, in each saddle bottom surface two supporting legs are installed respectively, supporting leg downward extension parallel to each other.
Preferably, opposed saddle surface links together by the welding cushion block.
In addition, described saddle is preferably square column, and this is for the ease of place jack on described provision for disengagement.
And, because jack weight is big, so saddle preferably adopts steel material.
The method for dismounting of rocker arm of coal mining machine planetary reduction box water distribution dish described in the utility model is design like this, comprises the following steps:
(1) water distribution dish and driving square toes one are removed from planetary reduction box;
(2) take out the center water pipe from the water distribution dish with among driving square toes;
(3) operation technique scheme 1 described provision for disengagement makes its four supporting legs down square above driving head;
(4) on described provision for disengagement, place jack;
(5) insert a shank of bolt in hollow type jack central authorities, and described shank of bolt is therefrom passed at edema with the heart involved pipe place;
(6) on the two ends of the screw rod that exposes, larger-size pad spare of each suit, the external diameter of top pad spare be greater than the diameter in water pipe hole, center, and the external diameter of bottom pad spare is greater than the diameter that drives square toes, and utilize fixture will above-mentioned two to fill up parts to be fastened on the screw rod;
(7) operation jack, jack makes progress jack-up and the water distribution dish is pulled out.
In addition, be bolt and nut component at the fixture described in the step (4).
Preferably, in step (7) by motorized motions machine operation jack.
By adopting technique scheme, can remove and install water distribution dish and driving square toes on the rocker arm of coal mining machine planetary reduction box quickly and safely, thereby improve the serviceability of equipment, adapted to the production model of the high-yield and high-efficiency in the domestic coal mine operation.

The specific embodiment
Below, 1 the utility model is described in conjunction with the accompanying drawings by embodiment.
According to Fig. 1 as can be known, in the prior art, planetary reduction box comprises: water distribution dish 1, drive square toes 2 and run through water distribution dish 1, drive the center water pipe 4 of square toes 2, water distribution dish 1 combines with driving square toes 2 by interference fit, thereby be installed on the rocker arm of coal mining machine planetary reduction box, and there is a center water pipe 4 to run through water distribution dish 1 and the inside that drives square toes 2, the cooling water of outside is incorporated into the inside of rocker arm of coal mining machine planetary reduction box.
Planning with water distribution dish 1 can to adopt provision for disengagement described in the utility model when planetary reduction box disassembles.
The provision for disengagement that the utility model adopts comprises: two column saddles 11 and be installed in supporting leg 12, two saddles parallel opposed each other on the described saddle respectively are equipped with two supporting legs in each saddle bottom surface, supporting leg downward extension parallel to each other.
