Single-beam crane generally has four operation wheels, adopts 1/2 to drive, and two cover adhesion wheel groups and the passive set of wheels of two covers are arranged respectively, and the adhesion wheel group is directly driven by electrical motor and speed reduction gearing.Because the production tolerance of the installation error of operation track for crane, the manufacture deviation of motor speed, wheel diameter and installation deviation (vertical divergence and lateral deviation), electric block need to be in reasons such as the mobile operations of girder, the adhesion wheel running orbit of single-beam crane both sides can not be two parallel straight lines on the factory building track, must be S shape.The various superpositions that cause the factor of deflection operation will shorten the cycle of deflection operation, even rail (wheel rim side and track side surfaces rub) phenomenon can occur seriously to gnaw.
Seriously gnaw rail in the cart operational process, to apparatus body and factory building gets on the right track and the building such as basis all can cause damage.Comprise: ⑴ shortens the normal service life of wheel wheel in service life should be more than 5 years, gnaw rail when serious wheel can only use some months～1 year.⑵ shorten track service life, damages installing and fixing of track.⑶ increase running resistance, and the resistance when gnawing the rail operation is under normal circumstances 1.5～3.5 times, increased the load of motor and transmission device, can impel burn-down of electric motor or retarder drive shafts fracture when serious.⑷ cause wheel to climb up rail level, and derailing, initiation equipment and human casualty accident appear in hoisting crane.
The way that the solution crane in bridge type is gnawed rail has multiple, such as the configuration design that improves wheel rim, reduce wheel manufacturing and assembly error, reduce track installation error, adopt the electrical motor of identical lot number etc., but effect is limited in the scope of standards and norms license.For single-beam crane, adopt the installation cost of automatic speed-measuring and correction to increase again too much, the horizontal wheel that adopts on the special-purpose crane in bridge type again complex structure, bulky, cost is also higher, be not easy to install and use.Therefore adopt simple in structure, make and easy, lower-cost Novel horizontal wheel is installed is just become and improve drive ability, prevent that single-beam crane from gnawing the desired solution of rail.
Adopt horizontal wheel simple in structure, with low cost to correct the deflection operation, prevent from gnawing rail at the single-beam crane product, at home and abroad be not reported on the document.
Summary of the invention:
The object of the invention is to overcome the defective of above-mentioned prior art, a kind of drive ability that improves single-beam crane be provided, prevent from moving deflection and gnawing, and simple in structure, cost is lower, the preventing gnawing rail mechanism of easy for installation, service-strong single-beam crane.
The technical scheme of taking for achieving the above object is:
A kind of preventing gnawing rail mechanism of single-beam crane is characterized in that: at end carriage two of single-beam crane the horizontal wheels of one cover are installed respectively.
Described horizontal wheels comprise horizontal wheel, by bearing axle are installed in the described horizontal wheel, and this axle one end is set with stop washer, and the other end is set with the seat board that can be fixed on the crane end carriage head.
The stifle sealing is adopted in the horizontal wheel end of described installation drag washer one end.
Described bearing is double-row self-aligning roller bearing.
Above-mentioned horizontal wheels and track head leave the 2-3mm gap.
The present invention prevents from gnawing the technology transplant of rail to the product of single-beam crane with original employing horizontal wheel that is applied on the special-purpose crane in bridge type, and the Novel horizontal wheels that suitable single-beam crane end carriage uses have been designed, it is welded on two heads of single-beam crane one butt beam lower cover by seat board, horizontal wheel and track head stay the gap of 2-3mm, master on this butt beam, passive wheel rim width are less, under the restriction of two horizontal wheel along the track linear running; Main, larger by the wheel rim width of motor car wheel on another butt beam, the installation error with the compensation track guarantees wheel rim and track side surfaces no touch in operational process.Thereby it is curved to reach hoisting crane operational process elimination S, eliminates and gnaws phenomenon.Compare with original technology, the present invention is simple in structure, and is easy for installation, and result of use is better.Be conducive to prolong the service life of set of wheels and track, the service life that prolongs electrical motor and speed reduction gearing, saving manufacturing cost and working service cost.
This invention has obtained the practical proof of separate unit beam crane, and running orbit is straight line basically after measured, even horizontal wheel contacts with track side surfaces, also is friction of rolling, can not gnaw the rail phenomenon.
