Abstract
The utility model relates to an elastic force fastening device used for a steel rail, particularly a steel rail of a crane. The utility model comprises fasteners which are arranged under both sides of a steel rail and an elastic press strip which is in lock joint with the fasteners. The elastic press strip press the steel rail by an elastic edge. The utility model which can cause the steel rail to always bear the action of pressing force has the advantages of firm and reliable steel rail, non looseness, double effects of looseness resistance and shock absorption, simple structure, convenient installation and maintenance, and strong anti-creeping performance.
Description
The utility model relates to the elastic force fastener of a kind of rail, particularly steel rail for crane.
Rail is because its bearing capacity height, and guidance quality, stationarity are good, and frictional force is low and be widely used in railway and crane operation field.It is fastening that existing steel rail for crane adopts following dual mode usually, one is the bolt clip plate device, it is made of bolt and pressing plate, pressing plate by the rail both sides compresses rail and reaches fastening purpose, this fastener is under dynamic load effect, add the creep of screw thread self, easily produce looseningly, make the rail changing of the relative positions and accidents caused back and forth; It two is a wedge block self locking type presser device, it includes upper and lower pressing plate, locking by contract iron between last lower platen comes fastening rail, this fastener is owing to be to come pretension by bolt also, under the lateral force that produces when crane moves is impacted, also easily generation is become flexible and self-locking was lost efficacy, and causes rail loosening and accidents caused.
The purpose of this utility model is to provide at the deficiency of above-mentioned prior art existence a kind of rail elastic force fastener of non-bolt, and it can effectively prevent the loosening of rail.
The purpose of this utility model is realized by following technical scheme: comprise the fastener of installing in the rail down either side 1, with the elastic layering 3 that fastener is interlockingly connected, elastic layering compresses rail by elastic edge.
When the utility model uses, be attached on the crossbeam 7 wing plate faces or install fastener on the basal plane of rail 6, then it with the vertical dieback in rail limit after fixing with crossbeam wing plate face or basal plane by welded by force direction, use special-purpose compaction tool that elastic layering is pressed into the connection position of fastener, make the elastic edge of elastic layering press the task that rail can be finished fastening rail.
Good effect of the present utility model is: 1, because the effect of elastic layering makes rail can keep in touch with it all the time when work generation distortion in service and vibration, and be subjected to the effect of elastic layering thrust all the time, the amplitude of rail is big more, the distortion of elastic layering is also big more, and the thrust that produces is also bigger, therefore it is solid and reliable to compress rail, be difficult for loosening, have locking and double effects vibration damping: 2, the anti-performance of creeping of rail is strong, and can reduce the influence of variation of ambient temperature to rail joint and rail body intensity; 3, simple in structure, be convenient to making, installation and maintain and replace.The utility model can be widely used on the crane runway of indoor and outdoor.
Fig. 1 is the stereogram of fastener among embodiment of the utility model.
Fig. 2 is the stereogram of elastic layering among embodiment of the utility model.
Fig. 3 is the user mode stereogram that the utility model and rail configuration are installed.
Fig. 4 is that elevation is installed in the use of an embodiment of the utility model.
Fig. 5 is the use installation side view of another embodiment of the utility model.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include fastener 1, it is block that fastener is, the front portion is provided with down the connection position 2 of button, be used for snapping elastic layering 3, elastic layering is the e type, being rotated by elastic steel strip forms, and the centre is provided with commissural flange 5, one sides and is provided with elastic edge 4, upwards dig at the rear portion of whole elastic layering, elastic layering also can be made other rotary type, and the cross section of elastic steel strip can be circle or rectangle, and elastic layering is interlockingly connected with fastener by its commissural flange 5, be fixed in a side of rail 6 by fastener, its elastic edge 4 is pushed down rail downwards, and fastener then welds on the wing plate face that is fixed on crossbeam 7, and the elastic force fastener can symmetry or staggered both sides of installing in rail, rail is fastening, and the elastic pressure of withholding rail usually is not less than 11KN.In addition, for further preventing getting loose of elastic layering and fastener, can below another side of elastic layering, offer back stop slot, a side relative set backstop projection 8 on fastener 1, like this after elastic layering is pressed into the connection position of fastener, back stop slot and backstop projection phase configuration can more effectively prevent deviating from of elastic layering, and have anti-theft feature preferably.
