Description

A kind of new forging bearing of conveyer

Technical field

It the utility model is related to the conveying equipment technical field of coal mine underground coal bed exploitation, specifically a kind of conveyer With new forging bearing.

Background technology：

At present, as the rapid development of high working face fully mechanized coal winning technology, hydraulic support also develop to heavy-duty, The power of trying to stop people from fighting each other of support increases therewith.This requires drag conveyor and hydraulic support connection part to have enough intensity, to adapt to liquid Press support pushing and sliding, the demand tried to stop people from fighting each other.The connection of the outer side shield of scratch board conveyor lead-over groove, headstock, aircraft tail shelf relies on bearing spiral shell Bolt is fastened, and carrier setting bolt will be embedded in bearing, that is, the final stress point of power of trying to stop people from fighting each other, on bearing, the intensity of bearing is direct Influence face end support, transition bracket pushing and sliding, can try to stop people from fighting each other smooth.Existing bearing is casting bearing, and low intensity is matched Carrier setting bolt head be sphere, manufacturing cost is higher.The utility model forges bearing, and its intensity has very big compared with casting bearing Lifting, meets to the intensity requirement of bearing when high working face hydraulic support is tried to stop people from fighting each other, and matched bolt head is plane, processing Cost is relatively low.The effective high reliability of scratch board conveyor of the utility model, while also reduce the manufacturing cost of conveyer.

The content of the invention：

The purpose of this utility model is to be to provide a kind of forging bearing, is met when high working face hydraulic support is tried to stop people from fighting each other to bearing Intensity requirement, the effective reliability for improving scratch board conveyor.

The technical solution adopted in the utility model is：A kind of new forging bearing of conveyer, it is characterised in that：Forging branch Seat 2 is process using Integral die-forged, and appearance profile is the cylinder with pattern draft.P ends are round boss, are put down on boss Face center is O-shaped slotted hole L.C faces are the cancave cambered surface in the range of circumferentially, and A is half arc labeled slots, and D is outlined groove profile Face, B faces are groove floor.

Described new forging bearing, it is characterised in that forging bearing 2B faces are plane.

Described new forging bearing, it is characterised in that groove back side appearance profile face is U-shaped, and outlined groove profile U Shape mouth direction is identical with half arc labeled slots A positions direction.

Described new forging bearing, it is characterised in that wide on the outside of the U-shaped groove of the groove back side, inner side is narrow.And slot center There are certain offset, slot center line and half arc labeled slots A center lines on branch with the O-shaped slotted hole center of boss plane Seat center line is symmetrical.

Described new forging bearing, it is characterised in that the cancave cambered surface C in the range of circumferentially is as fixed forging bearing Welding groove surface.

The utility model this have the advantage that：Meet that support with great mining height is tried to stop people from fighting each other the needs of power, improves high-power, large conveying quantity The reliability of scratch board conveyor, while reduce the manufacturing cost of conveyer.

The technical solution of the utility model is described in detail with reference to the accompanying drawings and detailed description.

Embodiment

The utility model provides a kind of conveyer forging bearing, and from Fig. 1~4, forging bearing 2 uses Integral die-forged It is process, appearance profile is also being accurately positioned beneficial to bearing while beneficial to processing and manufacturing with pattern draft.

Understand that P ends are round boss by Fig. 3~8, planar central is O-shaped slotted hole L on boss, carrier setting bolt O during use 180 ° of upset in type slotted hole, groove floor B positioning is blocked using bolt I6M faces.Boss outer surface is plane, and bottom baffle Uniform force when riser 3 contacts.

Understand that A is half arc labeled slots by Fig. 3~5.D is U-shaped outlined groove profile face, and outside is wide, and inner side is narrow.Outside groove Shape profile U-shaped mouth direction is identical with half arc labeled slots A positions direction.Slot center and the O-shaped slotted hole of boss plane There is certain offset at center, and slot center line and half arc labeled slots A center lines are symmetrical on bearing center line.In use, Bolt is put at index face A, 180 ° of rotation simultaneously pushes away toward the outer slot direction of U grooves, makes slot center line and bolt centerline Coincidence.

C faces are the cancave cambered surface in the range of circumferentially as shown in Figure 3, circumferentially in the range of cancave cambered surface C forged as fixed The welding groove surface of bearing, P ends are outwardly during welding.

A is understood as mark by Fig. 1~4, because forging bearing 2 wants back-to-back arrangement when lead-over groove side plate 1 welds, so as to Accurate positioning, direction is differentiated during convenient welding after marking.

From Fig. 5~6, hydraulic support power of trying to stop people from fighting each other acts on forging by bottom baffle riser 3 and bolt I6, bolt II8 On bearing 2, casting bearing 7, nut 5 is stop nut, and bolt I6 bolt II8 grades are 12.9.In design, mainly pass through guarantor The intensity and its weld strength with lead-over groove side plate 1 of card forging bearing 2 are come the needs that ensure normal pushing and sliding, try to stop people from fighting each other.Through experiment The test forging Fracture Force of bearing 2 is 850kN, the casting Fracture Force of bearing 7 is 500kN.On a conveyor, bearing is typically used for machine Head, tail and lead-over groove, the use of minimum place is headstock and lead-over groove connection place, one side arranges 3 bearings, and forging branch seating force is 2500kN.It is 1500kN to cast branch seating force, and high working face hydraulic support tries to stop people from fighting each other power typically in more than 1400kN, and safety coefficient is too Low, if running into bracket base occurs other situations such as swipe, bearing is easily drawn bad.Compared with casting bearing, forge bearing 2 Intensity be greatly improved.

E, F face are arc shape as shown in Figure 7, and processing and manufacturing difficulty is big, and cost is higher.

N, M face are plane as shown in Figure 8, manufacture easy to process, and cost is relatively low.

The detailed description that technical solutions of the utility model are carried out by preferred embodiment above be it is schematical rather than Formal limitation.Those skilled in the art can be remembered on the basis of the utility model specification is read to embodiment The technical scheme of load is modified, or equivalent substitution is carried out to which part technical characteristic, and these modifications or replacement, and The essence of appropriate technical solution is not set to depart from the scope of technical solutions of the utility model.
