Description
Technical Field
The utility model relates to a dry sediment machine field, concretely relates to a tear axle ware open for demolising dry sediment machine and support bearing roller axle.
Background
The dry slag machine system is an important auxiliary equipment for coal-fired power generation and chemical enterprises, the supporting rollers are important parts of the dry slag machine, the number of the supporting rollers is large, and each dry slag machine has about 350 and 400 supporting rollers. The supporting carrier roller can be changed a large amount of supporting carrier roller bearings when the unit is overhauled every year under adverse circumstances such as high temperature, dust, and the axle that needs to demolish the supporting carrier roller when changing the bearing is the difficult point, the key of this work, and the maintenance time that also needs is the longest.
At present, two methods for removing the shaft exist in the field, wherein the first method needs three grabbing and pulling horses to assist in removing and needs a large amount of manpower and maintenance time; the second kind strikes the axle through the manual work and realizes demolising, though this kind of operation is fairly simple, nevertheless damages axle and supporting roller body easily, has the maintainer to pound and injure the risk moreover.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a shaft dismounting device for dismounting a dry slag machine supporting roller shaft.
The utility model discloses a realize through following technical scheme:
the utility model provides a tear axle ware open for demolising dry sediment machine supports bearing roller, includes the fixed box of hydro-cylinder, the fixed box front end of hydro-cylinder is fixed with the T shape box intercommunication of placing the support bearing roller, be provided with hydraulic cylinder in the fixed box of hydro-cylinder, hydraulic cylinder's piston rod front end is fixed with the apical axis head through locking screw, the inside both sides of T shape box are fixed with the L shape fastener of joint support bearing roller flange, T shape box front end is opened has the axle hole that goes out of just to the apical axis head.
Preferably, a hydraulic station is arranged on the outer side of the oil cylinder fixing box body, a hydraulic pump is arranged on the hydraulic station, an outlet of the hydraulic pump is connected with an inlet of an electromagnetic valve arranged on the hydraulic station, and an outlet of the electromagnetic valve is connected with the hydraulic oil cylinder through an oil path pipe.
Preferably, the top of the oil cylinder fixing box body and the top of the T-shaped box body are arranged in an open mode.
Preferably, the shaft inside the support idler is aligned with the head of the jacking shaft.
Compared with the prior art, the beneficial effects of the utility model are that: this practical structure letter convenient operation, greatly reduced demolish the axle of support roller and to the spoilage of body and axle, suitable reducible maintainer quantity simultaneously reduces the cost of overhaul, has improved work efficiency.
Drawings
Fig. 1 is a perspective view of the structure of the present invention;
FIG. 2 is a schematic view of the present application in use;
in the figure: the hydraulic cylinder fixing device comprises an oil cylinder fixing box body 1, a hydraulic oil cylinder 2, a top shaft head 3, a locking screw 4, a T-shaped box body 5, a shaft outlet hole 6, an L-shaped clamping piece 7, a hydraulic station 8, a hydraulic pump 9, an electromagnetic valve 10, an oil path pipe 11, a supporting carrier roller 12 and a shaft 13.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1 and 2, the shaft dismantling device for dismantling the supporting carrier roller shaft of the slag drying machine comprises an oil cylinder fixing box body 1, wherein the front end of the oil cylinder fixing box body 1 is communicated and fixed with a T-shaped box body 5 placed with a supporting carrier roller 12, a hydraulic oil cylinder 2 is arranged in the oil cylinder fixing box body 1, the front end of a piston rod of the hydraulic oil cylinder 2 is fixed with a top shaft head 3 through a locking screw 4, L-shaped clamping pieces 7 clamped with flanges of the supporting carrier roller 12 are fixed on two sides in the T-shaped box body 5, and a shaft outlet hole 6 which is aligned with the top shaft head 3 is formed in the front end of the T-shaped box.
The hydraulic station 8 is arranged on the outer side of the oil cylinder fixing box body 1, a hydraulic pump 9 is arranged on the hydraulic station 8, an outlet of the hydraulic pump 9 is connected with an inlet of an electromagnetic valve 10 arranged on the hydraulic station 8, and an outlet of the electromagnetic valve 10 is connected with the hydraulic oil cylinder 2 through an oil pipeline 11.
The top of the oil cylinder fixing box body 1 and the top of the T-shaped box body 5 are arranged in an open mode.
The shaft 13 inside the supporting idler 12 is aligned with the head 3.
The working principle is as follows: when the utility model is used, the bearing cover at the front end of the support carrier roller 12 detached from the slag drying machine is detached, the bearing clamp spring is taken out, then the support carrier roller 12 is placed in the T-shaped box body 5, and the flange of the support carrier roller 12 is clamped in the L-shaped clamping pieces 7 at two sides in the T-shaped box body 5 to be fixed in the placing process, so that the support carrier roller 12 can be prevented from shaking, and the shaft 13 of the support carrier roller 12 can be ensured to be just opposite to the jacking shaft head 3;
the hydraulic pump 9 of hydraulic pressure station 8 is started, hydraulic pump 9 drives hydraulic cylinder 2's piston rod antedisplacement, the apical axis head 3 of hydraulic cylinder 2's piston rod front end contacts with the axle in the support bearing roller 12 and ejecting it, axle 13 can come out along axle hole 6 and break away from support bearing roller 12 in the support bearing roller 12 simultaneously, break away from the piston rod of back operation solenoid valve 10 control hydraulic cylinder 2 and withdraw the action in order to use next time, tear down like this and take out whole easy operation, be convenient for observe, greatly reduced demolishs the axle of support bearing roller and to the spoilage of body and axle, suitable reducible maintainer quantity simultaneously, the maintenance cost is reduced, and the work efficiency is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
