Description
Technical field
The utility model belongs to machinery field, is related to a kind of specific purpose tool of underground dismounting axis pin.
Background technology
Within coal mines, the axis pin of fully-mechanized mining working equipment transmission portion in use, because of abrasion, corrosion, damage etc.
Reason unavoidably needs to carry out dismounting and change operation, and because subsurface environment is severe, the unfavorable factor such as humid environment, result in pin
Axis corrosion is serious, and damaged condition severity is difficult to dismantle, or even is often taken effect very in disassembly process with conventional methods, Work tool
It is micro-, it there may come a time when to dismantle, so as to influence normally to keep the safety in production.For this reason, it is necessary to invent a kind of underground dismounting axis pin
Specific purpose tool, solves the problem that underground equipment transmission portion axis pin is difficult to dismantle.
Utility model content
In order to overcome the problems of the above-mentioned prior art, the purpose of this utility model is to provide a kind of underground release pin
The specific purpose tool of axis, solves underground equipment transmission portion axis pin in real production process and is difficult to dismantle or non-detachable asks
Topic.
The utility model is to be achieved through the following technical solutions：
A kind of specific purpose tool of underground dismounting axis pin, including steel bar and leading screw, wherein, the midpoint of the steel bar opens up leading screw
Pin hole, the screw rod of leading screw are connected through leading screw pin hole and with the inner bolt hole of axis pin to be removed, nut and the leading screw pin hole of leading screw
Cooperate so that the nut of steel bar and leading screw connects.
Preferably, the steel bar is I-steel.
Preferably, the both sides of the I-steel set stiffener plate, and leading screw pin hole passes through stiffener plate.
Preferably, the point midway of stiffener plate is welded with thickening steel plate, and leading screw pin hole, which passes through, thickeies steel plate.
Preferably, the I-steel is 10~20# I-steel.Further, I-steel selects 11# I-steel.
Preferably, the length of the I-steel is 60~100cm.Further, the length of I-steel is 80cm.
Preferably, the leading screw pin hole is the through hole of 30~42mm of internal diameter.
Compared with prior art, the utility model has technique effect beneficial below：
The utility model provides a kind of specific purpose tool of underground dismounting axis pin, including steel bar and leading screw, wherein, the steel
The midpoint of bar opens up leading screw pin hole, and the screw rod of leading screw is connected through leading screw pin hole and with the inner bolt hole of axis pin to be removed, leading screw
Nut and leading screw pin hole cooperate and realize that the nut of steel bar and leading screw is connected.When in use, the screw rod of leading screw passes through leading screw
Pin hole is simultaneously connected with the inner bolt hole of axis pin to be removed, and nut and the leading screw pin hole of leading screw cooperate, in this way, steel bar passes through silk
Thick stick is connected on axis pin to be removed；Steel bar can be rotated first so that steel bar drives the nut of leading screw to away to be removed
Axis pin direction is moved, and when nut reaches screw rod end stop motion, the effect of inertia of steel bar will be conducted by screw rod to waiting to tear open
The axis pin unloaded, drives axis pin to be removed to move out.In such a mode, steel bar is used as long-drawn-out hammer.If steel bar is as long-drawn-out
When hammer uses and cannot take out axis pin to be removed, then a jack, jack one end top are set respectively in the both sides of screw rod
Firmly steel plate, the other end withstand the base of axis pin to be removed, by jack so that axis pin is removed.There is provided using the utility model
Underground dismounting axis pin specific purpose tool, solve underground equipment transmission portion axis pin in real production process and be difficult to dismantle or not
The problem of dismantling.
Brief description of the drawings
Fig. 1 is the structure diagram of the steel bar of the utility model.
Fig. 2 is that the specific purpose tool structure diagram of axis pin is dismantled in the underground of the utility model.
Wherein：1 is I-steel；2 be leading screw pin hole；3 be thickening steel plate；4 be stiffener plate；5 be leading screw.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, a kind of specific purpose tool of underground dismounting axis pin, it includes steel bar and leading screw 5.Wherein, 11#
The both sides welding stiffener plate 4 of I-steel 1, the center weld of I-steel 1 thicken steel plate 3, form steel bar.In the centre drill of steel bar
The through-core hole of Φ 42 is as leading screw pin hole 2.The screw rod of leading screw 5 connects through leading screw pin hole 2 and with the inner bolt hole of axis pin to be removed
Connect, the nut of leading screw 5 cooperates with leading screw pin hole 2 realizes that steel bar and the nut of leading screw 5 are connected.
Wherein, for convenience, thickening steel plate 3 can be welded in stiffener plate 4.
Wherein, for fixed convenience and firm, the nut of steel bar and leading screw 5 can be welded directly together, and be realized solid
It is fixed.
When in use, the nut of the screw rod of leading screw 5 and leading screw 5 is coordinated, and the screw rod of leading screw 5 is connected to be removed
In the inner bolt hole of axis pin.First used steel bar as long-drawn-out hammer so that axis pin to be removed is removed by the effect of inertia of steel bar.
If steel bar uses as long-drawn-out hammer and cannot take out axis pin to be removed, set respectively in the both sides of screw rod one it is very heavy
Steel plate is withstood in top, jack one end, and the other end withstands the base of axis pin to be removed, by jack so that axis pin is removed.
The specific purpose tool of this underground dismounting axis pin can use waste and scrap to make, easy to operate, easy to use, make in the past
Dismantled with random Work tool, in disassembly process, the axis pin that happens occasionally can not take out or damage the phenomenon of Work tool, so as to influence
Normal production, after this write off axis specific purpose tool, as long-drawn-out hammer can not take out when, be exchanged with jack support point, coordinate very heavy
The booster action on top, can easily be drawn off, it is ensured that while safe, production has obtained effective guarantee.
In one kind practice operation, I-steel 1 is 10~20# I-steel 1, and the length of I-steel 1 is 60~100cm, silk
Lever pin hole 2 is the through hole of 30~42mm of internal diameter.In this way, can ensure the easy to use of specific purpose tool, special tool in turn ensure that
There is enough quality, so as to larger inertia.
Wherein, it is described at the center of steel bar, refer to the geometric center of the web of I-steel 1, leading screw pin hole 2 is opened in
On web.
