Abstract
The utility model discloses a rail expansion joint structure for a bridge crane for solving the problem that the existing rails are easy to move. The rail expansion joint structure for the bridge crane comprises left and right opposite rails with inclined planes. Connecting plates are arranged at both sides of rail waists at the ends of the two rails. The connecting plates and the rail waists at the ends of the two rails are respectively correspondingly provided with bolt holes. The bolts on the connecting plates are elongated bolt holes capable of being used for bolts to slide left and right. The two rails are fixedly connected with the connecting plates through the bolts. Due to the rail expansion joint structure disclosed by the utility model, the ends of the two rails are fixed by the bolts and the connecting plates, so that the movement of the rails is limited fundamentally, rail expansion joints cannot become excessively large or be extruded mutually to be misplaced due to the deviation of the ends of the two rails, strong vibration cannot be generated or a wheel flange cannot be clamped when wheels pass through the rails, and the safety operation of the bridge crane is further guaranteed.
Description
Technical field
The utility model relates to a kind of crane in bridge type orbit telescopic seam structure.
Background technology
In cold-rolling thin plate was produced, the production links such as entrucking of each unit material loading, rewinding and finished product volume all needed the cooperation of crane in bridge type.Because produce the increase of maximization, serialization and the reservoir area of unit, the track length of crane in bridge type does not wait from 100m to 1000m.In use find, when track length surpasses 200m, temperature influence, the phenomenon of expanding with heat and contract with cold is serious, and track often ruptures, and therefore must set up orbit telescopic seam to track, eliminates the fracture that causes because of het expansion and cold contraction.45 ° of right inclined-planes mutually about existing orbit telescopic seam becomes the end machining of two tracks reserve certain stretching, extension when mounted and shrink the slit.The flexible effect of operational phase is fair in the early stage, basic friction phenomenon when the crane in bridge type cartwheel roll is crossed expansion joint.But in long-term use, find; article one, through regular meeting 2～4 expansion joints are set on the track; be subjected to the propulsive effort of hoisting crane and the slight impact during by orbit telescopic seam influences; track generation play; can cause an expansion joint slit excessive like this; two terminations of another expansion joint are squeezed mutual dislocation.When wheel strong vibrations can take place during by big slit, each stressed member of car body is caused serious harm, when the expansion joint of wheel by mutual dislocation, can the wheel rim of wheel be done great damage, in addition wheel is stuck, had a strong impact on the normal operation of crane in bridge type.
The utility model content
The purpose of this utility model is to overcome the prior art defective, and a kind of crane in bridge type orbit telescopic seam structure that prevents the track play is provided.
The technical solution of the utility model is achieved in that a kind of crane in bridge type orbit telescopic seam structure, comprise about two the right mutually bevelled track of cutting, it is, be equipped with connecting panel in web of the rail both sides, two track terminations, on connecting panel and the two track termination webs of the rail respectively correspondence be processed with bolt hole, the strip shape bolt hole of bolt hole on the connecting panel for supplying bolt to horizontally slip, two tracks are captiveed joint with connecting panel by bolt.
Preferably, about described strip shape bolt hole two semicircles, last bottom is two straight lines.
The utility model orbit telescopic seam structure is compared with former expanded joint structure has increased by two connecting panels, two groups of bolts, and processed through hole at the track termination web of the rail, by bolt and connecting panel two track terminations are fixed together, fundamentally limited the play of track, make orbit telescopic seam can not become excessive or mutual extrusion misplaces owing to deviating from of two track terminations, wheel by the time can not produce sharp pounding or wheel rim is stuck, guaranteed the safe operation of crane in bridge type better.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure birds-eye view.
Among the figure, the 1-bolt; The 2-track; The 3-connecting panel; 4-strip shape bolt hole.
The specific embodiment
Be further described below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of crane in bridge type orbit telescopic seam structure, comprise about two the right mutually bevelled track 2 of cutting, be equipped with connecting panel 3 in web of the rail both sides, two tracks, 2 termination, the corresponding respectively strip shape bolt hole 4 that can horizontally slip for bolt 1 that is processed with on connecting panel 3 and the two track 2 termination webs of the rail, described strip shape bolt hole about 4 is two semicircles, and last bottom is two straight lines, two tracks 2 is captiveed joint with connecting panel 3 by bolt 1.
The utility model orbit telescopic seam structure is compared with former expanded joint structure has increased by two connecting panels 3, two groups of bolts 1, and processed through hole at the track 2 termination webs of the rail, by bolt 1 and connecting panel 3 two track 2 terminations are fixed together, bolt 1 can be free to slide by direction along ng a path in the strip shape bolt hole 4 of connecting panel 3, its sliding length scope is set according to the distance between center line and the expansion joint size of two bolts hole of two track 2 terminations, but limited the play of track 2, make orbit telescopic seam can not become excessive or mutual extrusion misplaces owing to deviating from of two track 2 terminations, wheel by the time can not produce sharp pounding or wheel rim is stuck, guaranteed the safe operation of crane in bridge type better.
