Abstract
The invention provides a toothed sleeve pulling device for a continuous miner. The toothed gear pulling device comprises a hydraulic pressure power supply unit, a hydrocylinder and a lead screw, wherein the hydraulic pressure power supply unit and the hydrocylinder are connected through a liquid path; the lead screw passes through the hydrocylinder; the tail of the hydrocylinder is fixedly connected with one end of the lead screw; the other end of the lead screw is fixedly connected with the toothed sleeve; the front end of a movable column of the hydrocylinder passes through the toothed sleeve, and a cylinder sleeve is sleeved on the movable column; the cylinder sleeve is fixed on a plunger through a nut; and the cylinder sleeve is used for sleeving the toothed sleeve and pressing against a toothed seat so as to pull the toothed sleeve out from the toothed seat. The hydraulic pressure power supply unit is a hydraulic pressure oil gun with a pressure more than or equal to 60 tons. The pressure is measured through a hydraulic pressure indicator. The open and close of the liquid path are controlled through a hydraulic controlled valve. Compared to the prior art, the toothed sleeve pulling device has a simple structure, avoids the hidden danger of underground fire, the underground fault can be removed at any time, and underground repairing time is reduced.
Description
Technical field
The present invention relates to a kind of cover of the tooth for continuous miner pull-up.
Background technology
Because the tooth cover on coal machine cutterhead toothholder often damages, need to often change.At present, when changing, due to fixing too tight between on-the-spot position limitation and part, mainly adopt two kinds of methods:
A kind of replacing method is to adopt welding to take off, but gets angry and carry out oxygen welding processing in down-hole, has the hidden danger of disaster hidden-trouble and actuation gas, and because the preparation of welding equipment is comparatively complicated, is therefore difficult to accomplish have at any time fault to be processed at any time.
Another kind of replacing method is to adopt manual type, with sledgehammer, impacts, and makes tooth overlap separated with toothholder or engage.But when mounting teeth is overlapped, impacting of sledgehammer is easy to maloperation, thereby causes hurting sb.'s feelings, sometimes impacts and forbidden also tooth cover to be smashed, and waste time and energy.
Therefore, be necessary to design a kind of novel tooth cover pull-up, to overcome the defect of prior art.
Summary of the invention
For the defect of prior art, the object of this invention is to provide a kind of safe, easy tooth cover pull-up.
Tooth cover pull-up provided by the invention comprises that hydraulic pressure is for power unit, hydraulic jack, leading screw, described hydraulic pressure is connected by liquid road with hydraulic jack for power unit, leading screw is through hydraulic jack, the afterbody of hydraulic jack is fixedly connected with one end of leading screw, the other end of leading screw is for being fixedly connected with tooth cover, the front end of the post alive of hydraulic jack is used for piercing into tooth cover, and on the post of living, cover has cylinder sleeve, cylinder sleeve is fixed on post alive by nut, described cylinder sleeve is used for entangling tooth cover and withstands toothholder, so that tooth cover is pulled out from toothholder, described hydraulic pressure is hydraulic pressure oil gun for power unit, the pressure of described hydraulic pressure oil gun is more than or equal to 60 tons, described pressure is observed by hydralic pressure gauge, opening and closing by pilot operated valve device of liquid road controlled.
Preferably, the afterbody of hydraulic jack is fixedly connected with leading screw by nut.
Preferably, by nut, leading screw is fixedly connected with tooth cover.
With respect to prior art, tooth cover pull-up of the present invention is not only simple in structure, and the hidden danger of having avoided down-hole to get angry, and can accomplish the eliminating at any time of down-hole fault, has reduced and has entered the time that well is repaired.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of tooth cover pull-up when pulling up tooth cover in a kind of specific embodiment of the present invention.
The specific embodiment
Fig. 1 is the schematic diagram of tooth cover pull-up when pulling up tooth cover in a kind of specific embodiment of the present invention.Described device comprises that hydraulic pressure is for power unit, hydraulic jack 102, leading screw 103, described hydraulic pressure is connected by liquid road with hydraulic jack 102 for power unit, leading screw 103 is through hydraulic jack 102, the afterbody of hydraulic jack 102 is fixedly connected with one end of leading screw 103, the other end of leading screw 103 is for being fixedly connected with tooth cover, the front end of the post alive 104 of hydraulic jack 102 is used for piercing into tooth cover, and on the post of living, cover has cylinder sleeve 106, and described cylinder sleeve 106 is for entangling tooth cover.Preferably, by nut, cylinder sleeve is fixed on post 104 alive.
Hydraulic pressure can be realized by hydraulic pressure oil gun 101 for power unit, for providing pressure to hydraulic jack 102, the output pressure of hydraulic pressure oil gun 101 can reach 60 tons or larger pressure, and described pressure can be observed by hydralic pressure gauge 120, and opening and closing of liquid road can be controlled by pilot operated valve device 130.
Leading screw 103 can adopt any applicable leading screw, preferably, by nut 140, effectively leading screw 103 and tooth cover 200 is fixed together.
As shown in Figure 1, in the process that tooth cover is pulled up from toothholder (not shown), when the post 104 of living is stretched out by hydraulic coupling, cylinder sleeve 106 entangles tooth cover 200 and withstands toothholder, because tooth cover 200 is fixed to one end of leading screw 103, the other end of leading screw 103 is fixed to again hydraulic jack outside, therefore leading screw and tooth cover all can not move, when hydraulic pressure oil gun 101 is given pressure, the post 104 of living stretches out, cylinder sleeve props up toothholder, the post of living pulls leading screw, because leading screw and tooth cover are fixed together, therefore, when pressure reaches certain value, leading screw 103 is pulled out tooth cover 200 from toothholder.
Although it will be understood by those skilled in the art that the present invention is described by above-mentioned preferred embodiment, its way of realization is not limited to above-mentioned embodiment.Should be realized that in the situation that not departing from purport of the present invention, those skilled in the art can make different variations and modification to the present invention.
