Description

The guide wheel device that fast assembling-disassembling is changed

Technical field

The utility model belongs to construction hoisting, draw gear, especially relates to a kind of guide wheel device.

Background technology

At present, in metallurgy, cableway engineering construction, when lifting or drawing with external force driving steel wire rope; Track adjusting wheel in use often because of unbalance stress or load excessive or use for a long time and wear and tear, bearing failure or track adjusting wheel phenomenon such as break often occurs; But existing track adjusting wheel is difficult for changing; Change dismounting steel rope earlier like need, reinstall after the new track adjusting wheel again with the steel wire penetrating track adjusting wheel, once more normal operation.Because of track adjusting wheel breaks down, steel rope must intert again, changes track adjusting wheel like this and just compares very complicated and delay the construction period, causes the overlapping investment of work manpower, and work efficiency is not high, has increased construction cost.

Summary of the invention

The purpose of the utility model is to propose the guide wheel device that a kind of fast assembling-disassembling is changed, and is easy to use, and that can realize track adjusting wheel disassembles replacing fast, need not to carry out interting again of steel rope again, improves work efficiency, reduces construction cost.

The purpose of the utility model realizes like this: the guide wheel device that a kind of fast assembling-disassembling is changed; It is characterized in that: the guide wheel device that this fast assembling-disassembling is changed mainly is made up of track adjusting wheel (guide wheel), last clamp, following clamp, front apron, middle baffle plate, back shield and track adjusting wheel bolt, nut; This track adjusting wheel is a steel casting; Circumference in track adjusting wheel is offered grooving; Centre in the side up and down of this track adjusting wheel has boss symmetrically and offers the center bolt hole; Clamp is for being horizontally disposed rectangular slab on this; On the lower surface of the right-hand member of last clamp middle part, vertically being welded symmetrically at interval is the front and rear baffle of side ⊥ shape, is about to this right-hand member of going up clamp middle part lower surface and leans and corresponding welding with the right angle incision on forward and backward baffle plate top, before this, the spacing (opening distance) between the back shield is slightly larger than the thickness of middle baffle plate and is free-running fit with middle baffle plate; This time clamp also be horizontally disposed and with the identical rectangular slab of last clamp size; The middle baffle plate that on the upper surface at following clamp right-hand member middle part, is welded the ⊥ shape that is side; The right-hand member middle part upper surface that is about to clamp under this leans and corresponding welding with the right angle incision of middle baffle plate bottom; Baffle plate is identical with forward and backward baffle arrangement in this; With middle baffle plate free-running fit be inserted between the forward and backward baffle plate and make down the clamp right-hand member and the right angle incision of forward and backward baffle plate bottom leans, offer suspension or the fixed orifice (point) of the through hole of concentricity line in the right part of front apron, middle baffle plate and back shield, in addition as this guide wheel device; On the section of the left side of upper and lower clamp, offer central through hole; The diameter in the center bolt hole on the diameter of this central through hole and the track adjusting wheel is identical, with the track adjusting wheel free-running fit be installed between the upper and lower clamp, install the track adjusting wheel bolt ordinatedly and install pad additional in cooresponding central through hole and intermediate gap, center bolt hole and use nut screwing clamping; Upper and lower clamp and track adjusting wheel are fused, in the grooving of track adjusting wheel, wear the extension steel rope.

The installation process of the guide wheel device that this fast assembling-disassembling is changed is following: on the track adjusting wheel bolt, install pad earlier, will descend clamp to pass the track adjusting wheel bolt, be installed on track adjusting wheel on the track adjusting wheel bolt; Install clamp and pad then, simultaneously, the middle baffle plate that descends the clamp right-hand member is installed between the forward and backward baffle plate of clamp right-hand member; Tighten clamp nut again; Combination cost guide wheel device, steel rope passes between track adjusting wheel and upper and lower clamp, accomplishes the change of steel rope sense of motion.

In the use, when this guide wheel device breaks down, at first suspend the external force effect; Steel rope is used the chain block working fastening; Behind the demolition clamp nut, do not carrying out changing any one group of parts on this guide wheel device under the interspersed again situation of steel rope, thereby realizing quick-replaceable purpose.

The guide wheel device that fast assembling-disassembling that the utility model proposed is changed, easy to use, that has realized track adjusting wheel disassembles replacing fast; Need not to carry out again interting again of steel rope; Save the time that track adjusting wheel is changed, improved operating efficiency, reduced construction cost.

The guide wheel device that at present combines accompanying drawing and embodiment that the fast assembling-disassembling that the utility model proposed is changed is further described.
