Description
Technical field
This utility model relates to hoisting machinery technical field, specifically relates to a kind of be applicable to various general and special elevator gate-type or the roll device of bridge crane.
Background technology
Publication No. 102773669A, publication date is that the Chinese patent literature on November 14th, 2012 discloses a kind of elevator subdivided rolling drum welding production method, solve existing method and cause that reel faying face contact area deficiency, blank quality poor stability, production efficiency be low, high in cost of production problem, all part faying faces are not processed before weldering, stay 8mm allowance, in whole welding equipments to reel；Half web or half support ring being put vertical car on postwelding in pairs and along vertical rotation vehicle wire processing excircles and welds cut, riveter offsets up at 8mm as the center of circle with cylindrical centrage, draws gas cutting reconditioning line, and riveter presses gas cutting reconditioning line reconditioning and shapes；The most again half spool body and remaining parts having machined faying face is welded together with them；After reel integrally annealed, take two halves reel, boring and milling half reel faying face apart, two halves reel is connected into entirety, increases the contact area of reel faying face, improve the stability of blank quality, decrease the number of times of vertical car, improve production efficiency, reduce product cost.
As described in 102773669A patent documentation, currently, the roll device of winding type crane short axle form is spool shaft and directly welds with reel web.The roll device of this welding generally includes the spool body of hollow cylindrical, spool shaft and two webs.Two row webs are positioned at coreless rolls inner barrel one end, and weld with spool body, have, on two webs, the through hole that supply spool axle runs through, and spool shaft is respectively welded fixing with two webs again.Such frame mode has the disadvantage in that
Firstly, since spool shaft is typically the high duty alloy steel forgings that mechanical performance is higher, its carbon content is the highest, solderability complex process, and axle welding quality is difficult to grasp.But weld seam is in high stress areas between spool shaft and reel web, therefore the highest to the prescription of its weld seam, if quality problems occurs in weld seam between spool shaft and web, its intractability is relatively big, and easily damages spool shaft, often results in spool shaft and scraps.Secondly, for Large Copacity crane, its this body contour of roll device is huge, the heaviest from weight, but all machined surfaces that expose of spool shaft are both needed to rear overall processing integrally welded with reel, cause reel difficulty of processing big, the working ability of process equipment is also had the highest requirement.It is greatly reduced the optional scope of reel process equipment, thus adds the cost of manufacture of reel, also affect the production cycle controllability of reel.
Summary of the invention
This utility model aims to the defect existing for above-mentioned prior art and deficiency, a kind of hoist roller device is provided, this utility model greatly reduces the making of reel, difficulty of processing, and quality easily ensures, production and processing cycle time, requirement to process equipment reduces, and effectively reduce reel manufactures cost.
This utility model realizes by using following technical proposals:
A kind of hoist roller device, including spool body, two webs and spool shaft, it is characterized in that: also include wheel hub and gland, said two web is provided with through hole, wheel hub one end passes described through hole, the wheel hub other end protrudes from web outside, between wheel hub and described web welded fixing, described spool shaft is placed in wheel hub formation hole axle assembly connection form, one end of spool shaft stretches out in outside wheel hub, described gland is enclosed within the shaft shoulder of the spool shaft stretching out in web outside, and gland uses fillet weld seam to fix with wheel hub end face.
Described reel web be material be the reel web of Q345 sheet material.
Described wheel hub is material ZG270 ~ 500 cast steel or the wheel hub of 35 forged steel.
Described gland is material Q235 or the gland of Q345 sheet material, has the gap of 2mm between gland and wheel hub.
Compared with prior art, what this utility model was reached has the beneficial effect that:
1, in this utility model, using and increase wheel hub, and spool shaft is placed in wheel hub formation hole axle assembly connection form, the solderability avoiding spool shaft is poor, and welding procedure is complicated, and weldquality is difficult to the difficult problem grasped.Thus avoid the problems such as the follow-up weldquality that may cause processes, spool shaft damage is even scrapped, reel making duration lengthening.
2, in this utility model, using and increase gland, gland materia uses common Q 235 or Q345 board making, and gland is enclosed within the gap after compression axis shoulder end face and having about 2mm in spool shaft between wheel hub, assembles the rear pressing cover that puts in place and uses fillet weld seam with wheel hub border.The contraction of available weld seam, makes gland spool shaft be compressed tightly against on wheel hub, thus when ensureing work, will not relatively rotate between spool shaft and wheel hub phenomenon.
3, in this utility model, spool shaft uses assembly connection form with spool body, spool shaft and spool body are the most individually processed, the processing of spool body no longer uses the mode that center holds out against, thus reduce the requirement to process equipment, add the optional scope of process equipment, effectively reduce the cost of manufacture of reel, it is possible to shorten the production cycle of reel.
4, in this utility model, reel web material uses Q345 sheet material, and boss material uses 35 forged steel or cast steel ZG270 ~ 500.Using Type of Welding to be connected between reel web and wheel hub, solder design part both sides' material welding usability is relatively good, and weld seam welding is not difficult, and weldquality is easily mastered.
