Description
Technical field
The utility model relates to the cylinder that uses in a kind of colliery underground equipment replacing process, particularly a kind of split type cylinder.
Background technology
In recent years, because coal mine output increases year by year, or coal seam conditions changes greatly, occur former well head in the equipment replacement process and can not satisfy the equipment requirement of going into the well, the prior art scheme adopts the outside connection of tube circle, a tube end flange to connect and be connected with blade respectively, it is fastening unreliable that architomia formula cylinder exists, even the situation that cylinder is thrown off from rocker arm of coal mining machine occurs.Perhaps the colliery operative employee is welded into one the split cylinder in the down-hole voluntarily with connecting plate, has potential safety hazard, and next time maintenance or cut open again when changing working face, has a lot of inconvenience.Prior art mainly has problems and is: (1) tube circle tie point is few, discontinuity equalization, and stressed significantly square bonding strength is low, and wheel hub adpting flange and tube end flange easily take place loosening; (2) end plate and tube circle slot are whole gas cutting after the cylinder welding, and there are a lot of slag nodules in the gas cutting face, and gap is bigger, and tie point place bolt is easily sheared; (3) wheel hub and flange connecting point are few, and bolt is not taked locking measure, and in case loosening inconvenience is fastening; (4) tube end flange and mounting flange tie point are few, and bolt is not taked locking measure, and be easily loosening.
The utility model content
The purpose of this utility model is to provide a kind of: the cutting resistance is little, connects reliably, and effect of loading coal is good, the split type cylinder that anti-wear performance is good.
The purpose of this utility model is achieved in that this cylinder comprises split type cylinder end plate, end plate junction plate, tube circle junction plate, blade, wheel hub, goes up adpting flange, blade junction plate, slotted nut, tube end flange, following adpting flange and tube circle, upper end in the tube circle outside is connected with split type cylinder end plate, be connected with the end plate junction plate in the lower end of split type cylinder end plate, lower end in the tube circle outside is connected with blade, is connected with the blade junction plate at the place of cutting apart in the tube circle outside; Top in the tube circle is connected with adpting flange and wheel hub, and wheel hub is connected on first circle, and last adpting flange is connected on second circle; A flange at the bottom of bottom in the tube circle is connected with tin, following adpting flange is connected with a tube end flange by slotted nut.
Thread mill drilling on the described tube end flange, 8 groups are uniform, and per 2 holes are one group; Than downside, tube circle connecting plate has 6 groups of connecting plates in the cylinder centre position to described blade joint at cylinder.
Be processed with through hole on the described wheel hub, 4 groups uniform, and described going up on the adpting flange is processed with screwed hole, and bolt is installed from hub side, and bolt head has iron wire to twine.
Beneficial effect: owing to adopted such scheme, 1) on the stressed abundant Calculating Foundation of cylinder, determine connecting portion and tie point, thereby determined multiple spot, from the inside to the outside fastening; Pass through respectively fastening end plate, blade, the tube circle, wheel hub and a tube end flange so that Split roller forms an integral body after assembling, satisfy strength demand;
2) twine the fastening method of very economicals such as method and slotted nut be fastening by the bolt head iron wire, realize powerful cylinder performance;
This Split roller has two half cylinder group to become, and the upper welding of first tube circle wheel hub welds adpting flange on second circle, manual oxygen cutting behind the tube end flange welding, and lower adpting flange is independently, is used for fastening cylinder during assembling.Upper and lower half circle gone into the well respectively when going into the well, and is assembled into one in the down-hole.Split type cylinder connected mode can effectively satisfy the reliability of cylinder in underground work, avoids the cylinder bolt looseness, accidents such as impression throw-off; Utilize cylinder space requirement and bolt strained state, guarantee that divisional plane is smooth, the junction plate gap is even, and after cylinder group was dressed up one, the divisional plane contact was even, and bolt strained equilibrium is avoided cutting off.Adpting flange under wheel hub, having, flange has lower adpting flange at the bottom of tube, and tube end flange also has a purposes to stop that exactly coal enters cylinder from cylinder bottom, protection planet head, wheel hub cuts side at cylinder, and tube end flange is in the defeated coal side of cylinder, both distances are suitable, connect by lower adpting flange; Equally, end plate is in cylinder cutting side outermost end, and than downside, tube circle connecting plate has 6 groups of connecting plates in the cylinder centre position to the blade joint at cylinder; Moreover, by end plate, the tube most of divisional plane slot of circle machine gas cutting before assembling, machine gas cutting before the assembling has guaranteed that the gas cutting face is smooth after the design of blade divisional plane.Upper adpting flange bolt adopts head iron wire winding method, and tube end flange also increases holding pin, and head is locking with slotted nut; This scheme has guaranteed the powerful cutting of cylinder, connects rationally, and loosing Prevention Technology is reliable.Cutting Drag is little, connects reliably, and effect of loading coal is good, and anti-wear performance is good, has reached the purpose of this utility model.
Advantage:
1, connects, connect reliably, adopt fastening bolt locking;
2, wheel hub and tube end flange are arranged fastening bolt from the end plate side, adopt locking device, have both realized that cylinder reliably connected, and have made things convenient for again the down-hole erection unit;
3, tube circle is cut apart place's connecting plate and is placed the tube circle inboard, has both improved effect of loading coal, again so that product is attractive in appearance;
4, split type cylinder end plate and tube circle are cut apart the most of slot in the place machine gas cutting of going ahead of the rest, and blade designs gas cutting in advance, has guaranteed product size, and the junction plate gap is even, bolt strained equilibrium, and the product integral working is reliable, and slot is smooth, and is attractive in appearance;
5, tube end flange and lower adpting flange except adopt fastening bolt join locking fastening, adopt steady pin to connect, the terminal employing of steady pin slotted nut is locking;
6, wheel hub and upper adpting flange, tube end flange and lower adpting flange connecting hole all adopt the mode in uniform hole, the wheel bore through hole, thread mill drilling on the upper adpting flange, tube end flange hole is with being with the seam through hole, thread mill drilling on the tube end flange; Stressed even, reliable operation;
7, tube end flange adopts the brill mode of joining with lower adpting flange fixed pin holes, after the cylinder assembling, joins to bore and processes, and has guaranteed the quality of fit with steady pin, and the processing technology reasonable, the expense less expensive.
