Description
Technical field
The present invention relates to power shovel maintenance technique field, a kind of renovation technique before the large-scale power shovel underframe longitudinal axis after bottom outlet abrasion.
Background technology
Power shovel is one of main extractive equipment of ten-million-ton scale surface mine, and it is high that it has productivity ratio, and operating rate is high, the advantages such as running cost is low, is the type generally acknowledged of current mining industry, is widely used in the industry surface mine exploitations such as domestic limestone, colliery, iron mine.Before the daily power shovel underframe longitudinal axis, the renovation technique after bottom outlet abrasion has two kinds: a kind of is according to greatest wear amount car circle bottom outlet position before the power shovel underframe longitudinal axis of abrasion, is equipped with copper sheathing according still further to hole size after processing；Another kind is that bottom outlet abrading section before the power shovel underframe longitudinal axis is carried out built-up welding, with grinder buffing, carries out equipped copper sheathing according still further to actual hole size and size.There is following technical problem in above two renovation technique: 1, power shovel underframe weighs 11.634 tons, after complete machine all being taken apart, power shovel underframe is delivered to machine shop processing endoporus, labor intensity is big, repair time needs about 60 days, and whole power shovel dismounting quantities is relatively big, transport is wasted time and energy back and forth；If 2 build the boring machine processing power shovel underframe bottom outlet when zero at the scene, the bottom outlet position of abrasion according to greatest wear amount boring circle, can be because of reasons such as on-the-spot place out-of-flatnesses, machining accuracy is greatly affected, the roughness of bottom outlet and the most very poor with circularity before the power shovel underframe longitudinal axis, the copper sheathing faying face of assembling is less, the most concentric phenomenon easily occurs when installing the longitudinal axis；3, bottom outlet abrading section before the power shovel underframe longitudinal axis being carried out built-up welding, with grinder buffing, carry out equipped copper sheathing according still further to actual hole size and size, the method there will be axiality and the most very poor with circularity, and equipment easily goes wrong after installing and using.
Summary of the invention
It is an object of the invention to provide bottom outlet restorative procedure before a kind of power shovel underframe longitudinal axis, this method can solve the existing power shovel underframe longitudinal axis before the labor intensity that exists of bottom outlet reparation is big, overhaul efficiency is low and repairs the problem that precision is low.
In order to solve the problems referred to above, the technical solution used in the present invention is: before this power shovel underframe longitudinal axis, bottom outlet restorative procedure comprises the following steps:
A, the longitudinal axis and the front bottom outlet copper sheathing of power shovel underframe being pulled down, whether the interstitial hole copper sheathing of detection power shovel underframe weares and teares, and then replaces interstitial hole copper sheathing if any abrasion；
B, one end of the described longitudinal axis being loaded in interstitial hole copper sheathing, make axially axial consistent with described interstitial hole of the described longitudinal axis, the other end of the described longitudinal axis stretches in the front bottom outlet of described power shovel underframe；
D, towards described gap portion inject metal repairing agent, make described metal repairing agent fill up described gap portion；
E, solidify after 2 hours until described metal repairing agent, i.e. complete to repair.
Before the above-mentioned power shovel underframe longitudinal axis in the technical scheme of bottom outlet restorative procedure, before more specifically technical scheme is it may also is that load interstitial hole by the longitudinal axis in step B, between described front bottom outlet and interstitial hole, a spacing adjusting apparatus is placed in power shovel underframe, described spacing adjusting apparatus includes adjustment block, jack and plain cushion, described plain cushion is arranged at described jack lower end, and described adjustment block is connected to the push rod external part of described jack；Regulate the height of described adjustment block with described jack, make the top of described adjustment block align with the bottom of the bore area of described interstitial hole copper sheathing.
Further, described metal repairing agent uses and can match the super metal repairing agent of new TS2111.
The above-mentioned super metal repairing agent of new TS2111 of matching is with the compound double combination patching materials of metal and the alloy polymer/metallic as aggregate.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that without dismounting whole power shovel, it is only necessary to dismounting parts thereof, repairs simple to operate, front and back dismount, fill up the reparation shared 4 day time, substantially increase the work efficiency of maintenance；Reduce the labor intensity of service worker, save nearly ten thousand maintenance cost more than 10；Accurate positioning, repairs precision high.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the prosthetic device that the present invention uses is installed on power shovel underframe.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
The invention will be further described for embodiment below in conjunction with the accompanying drawings:
Embodiment 1
Prosthetic device shown in Fig. 1 mainly includes interstitial hole copper sheathing 2, the longitudinal axis 3, the copper sheathing 1 repairing front bottom outlet and spacing adjusting apparatus, spacing adjusting apparatus includes adjustment block 4, jack 5 and the plain cushion 6 that thickness is 10 millimeters, plain cushion 6 is arranged at jack 5 lower end, and adjustment block 4 is connected to the push rod external part of jack 5.
In practical condition, the abrasion of the front bottom outlet copper sheathing of power shovel underframe and front bottom outlet itself is the most serious, and wear phenomenon did not occur in the interstitial hole of power shovel underframe, utilizing this feature, before using above-mentioned prosthetic device to carry out the power shovel underframe longitudinal axis, bottom outlet restorative procedure comprises the following steps:
A, the longitudinal axis 3 and the front bottom outlet copper sheathing of power shovel underframe being pulled down, whether the interstitial hole copper sheathing 2 of detection power shovel underframe weares and teares, and then replaces interstitial hole copper sheathing 2 if any abrasion；
B, in power shovel underframe, between front bottom outlet and interstitial hole, place spacing adjusting apparatus, adjustment block 4 height is adjusted with the jack 5 of spacing adjusting apparatus, align formation horizontal line with copper sheathing 2 endoporus bottom surface on the top making adjustment block 4, again one end of the longitudinal axis 3 is inserted in copper sheathing 2, adjustment block 4 abuts against with the longitudinal axis 3, the axis making the longitudinal axis 3 is consistent with axially bored line in copper sheathing 2, the other end of the longitudinal axis 3 then stretches in the front bottom outlet of the power shovel underframe longitudinal axis, such that it is able to easily found the center of front bottom outlet by the longitudinal axis 3；
C, being set with copper sheathing 1 on the longitudinal axis 3, be placed between the longitudinal axis 3 and front bottom outlet by copper sheathing 1, the gap portion 7 formed between copper sheathing 1 and front bottom outlet is the wearing part of front bottom outlet；
D, can match new TS2111 super metal healant A, B two component put together and be in harmonious proportion rapidly, load in applying glue cylinder after being in harmonious proportion uniformly, inject metal repairing agent by applying glue cylinder towards gap portion 7, make metal repairing agent fill up gap portion 7；
E, solidify after 2 hours until metal repairing agent, i.e. complete to repair.
Embodiment 2
