Description
Technical field
The utility model relates to a kind of rail pressing plate, belongs to field of mechanical technique.
Background technology
On overhead and gantry cranes and large-scale steel structure, trapped orbit is fixed to track on structure by pressing plate usually, pressing plate and the connection mode of support rail beam generally have welding to be connected two kinds with bolt: track and pressing plate is permanent is fixed on the support rail beam when the employing welding manner is not easy to maintenance and the replacing of track; General Requirements support rail beam is " work " font formula when with bolts, and the slightly large hoisting crane support rail beam of tonnage is mostly box-type section, this moment, traditional bolt connecting mode was auger shell pit on the support rail beam, make loaded down with trivial details, in case and thread failure also be unfavorable for dismounting and the installation of track.
The utility model content
Technical problem to be solved in the utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of crane rail pressboard apparatus of simple in structure, easy installation and removal is provided.
For solving this technical matters, the utility model provides a kind of detouchable crane rail pressboard apparatus, comprise pressing plate, fixation clip piece, eccentric shaft and nut, described pressing plate is provided with U-lag I, one bottom face of pressing plate is wedge shape, described fixation clip piece middle part is provided with U-lag II, vertical with this U-lag II groove that is provided with, and the middle part of described eccentric shaft is that screw thread, bottom are cam; Described pressing plate is arranged in the groove of fixation clip piece, eccentric shaft is located in the U-lag I and U-lag II of alignment, cam is concordant with pressing plate, with pressing plate, form cam mechanism, and pressing plate stretches out the fixedly tapered end of briquetting plate presses in orbit, and use nut and screw thread are fixed.
During described eccentric shaft clickwise, its cam is for compressing track trend, and the screw thread of eccentric shaft is right-hand thread.
The top of described eccentric shaft is six prisms.
Described pressing plate, fixation clip piece and eccentric shaft all adopt the method for casting to make.
Beneficial effect: the utility model can make the crane beam Assembly ﹠Disassembly easily that gets on the right track, be convenient to maintenance and replacing that beam gets on the right track, have advantages of that simple in structure, advanced technology, manufacture craft are simple, humanization designing, solved the crane beam inconvenient problem of dismounting that gets on the right track.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model pressing plate;
Fig. 3 is the structural representation of the utility model fixation clip piece;
Fig. 4 is the structural representation of the utility model eccentric shaft.
In figure: 1 pressing plate, 2 fixation clip pieces, 3 eccentric shafts, 4 nuts, 5U shape groove I, 6 wedge shapes, 7U shape groove II, 8 grooves, 9 six prisms, 10 screw threads, 11 cams.
The specific embodiment
Assembly ﹠Disassembly easily when the utility model is changed track.
Below in conjunction with drawings and Examples, the utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises pressing plate 1, fixation clip piece 2, eccentric shaft 3 and nut 4, and eccentric shaft 3 forms cam mechanism with pressing plate 1, can realize the motion of certain stroke of pressing plate 1 fore-and-aft direction by reversing eccentric shaft 3, thereby adjusts the compression degree of 1 pair of track of pressing plate.
Figure 2 shows that the structural representation of the utility model pressing plate.
Described pressing plate 1 is middle wedge shape 6 structures that have U-lag I5.
Figure 3 shows that the structural representation of the utility model fixation clip piece.
Described fixation clip piece 2 middle parts are provided with U-lag II7, vertical with this U-lag II7 groove 8 that is provided with.
Described pressing plate 1 is arranged in the groove 8 of fixation clip piece 2, and U-lag I5 aligns with U-lag II7, and wedge shape 6 ends of its center platen 1 stretch out fixation clip piece 2 outsides.
Figure 4 shows that the structural representation of the utility model eccentric shaft.
The bottom of described eccentric shaft 3 is cam 11, and middle part is screw thread 10, and top is six prisms 9.
Described eccentric shaft 3 is located in the U-lag I5 and U-lag II7 of alignment, and cam 11 is concordant with pressing plate 1, and cam 11 forms cam mechanism with pressing plate 1, and eccentric shaft 3 rotates and will impel pressing plate 1 toward the different directions motion to different directions.
During described eccentric shaft 3 clickwise, its cam 11 is for compressing track trend, the screw thread 10 of eccentric shaft 3 is right-hand thread, while making eccentric shaft 3 produce the movement tendency of conter clockwise because of the vibrations of track when pressing plate 1, with nut 4, be just in time locking state, nut 4 has also produced self-locking to a certain degree with eccentric shaft 3.
Described pressing plate 1, fixation clip piece 2 and eccentric shaft 3 all adopt the method for casting to make, and be with low cost, and processing is simple.
When attachment rail, at first with fixation clip piece 2 positioning weldings in the track both sides, bear the side force of track, then pressing plate 1 and eccentric shaft 3 are packed into successively in fixation clip piece 2, wedge shape 6 side pressures of pressing plate 1 in orbit, make pressing plate 1 compress track by six prism 9 rotation eccentric axis 3, then eccentric shaft 3 and fixation clip piece 2 use nuts 4 and packing ring are fastening good; When changing or keeping in repair needs dismounting track, at first unclamp nut 4, then rotation eccentric axis 3 de-orbits pressing plate 1, then pressing plate 1 and eccentric shaft 3 are easily taken out, and finally track is taken off.
Here fixation clip piece 2 bears the track side force, bears the track vertical force after pressing plate 1 compresses track.
The utility model can make the crane beam Assembly ﹠Disassembly easily that gets on the right track, and is convenient to maintenance and replacing that beam gets on the right track, has advantages of that simple in structure, handsome in appearance, advanced technology, manufacture craft are simple, humanization designing.
The above-mentioned embodiment of the utility model, just casehistory, be not only, all in the utility model scope or the change that is equal in scope of the present utility model all by the utility model, surrounded.
