Description

Technical Field

[0001] The invention relates to the technical field of crane rails, in particular to an aluminum alloy rail dedicated to cranes. Background Art

[0002] A crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. In factories, bridge cranes are generally used to lift and transfer heavy objects. Among them, a bridge crane is a lifting machine that is horizontally mounted on tracks at both ends of the factory building. The lifting trolley can run along the main beam, and the main beam can run longitudinally along the tracks on both sides, using the space below to lift materials. The two ends of the main beam of the bridge crane are respectively fixed on the end beam, and the end beam runs along the tracks on both sides of the factory building through rollers. Among the components of the crane, the crane track plays a very important role in carrying the crane for safe transportation. In addition, aluminum alloy tracks are often used in the application of some light lifting cranes.

[0003] At present, commonly used rails are generally fixed on the base using bolts and fasteners, but the fasteners are often small in size, difficult to store, and easy to lose. Summary of the invention

[0004] The purpose of the present invention is to provide an aluminum alloy rail specially used for cranes, so as to solve the problem that the rail needs to be fixed and installed using fasteners that are easy to lose during installation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a special aluminum alloy rail for cranes, comprising a rail body, the front and rear sides of the upper surface of the rail body are respectively provided with side guard plates extending vertically upward, a rotating plate is rotatably installed at the bottom end of the slots arranged at intervals in the side guard plates, a through hole is vertically opened on the surface of the rotating plate, a spring is sleeved in the through hole, both ends of the spring are respectively fixedly connected with an annular body, a circular annular through hole for installing bolts is opened at the center of the annular body, a connecting head is fixedly connected to one end face of the rail body, and a connecting groove is vertically opened between the upper and lower surfaces at the middle position of the other end of the rail body, the connecting head and the connecting groove are slidably engaged and matched in the vertical direction, the outer end of the connecting head is provided with a cross-section enlarged end, the inner end of the connecting groove is provided with a cross-section enlarged groove, and the cross-section enlarged groove and the cross-section enlarged end are slidably engaged and matched in the vertical direction.

[0006] Preferably, the bottom ends of the two side surfaces of the rotating plate are respectively vertically fixedly connected with rotating shafts, and the rotating shafts are respectively rotatably sleeved in cylindrical grooves opened at the bottom ends of the inner walls of the notches of the side guard plates.

[0007] Preferably, the bottom end of the rotating plate is a horizontally placed cylinder, and the outer wall of the cylinder is tangent to the bottom surface of the track body and the outer surface of the side guard plate respectively, and the rotating shaft is fixedly connected to the center position of the two end surfaces of the cylinder at the bottom end of the rotating plate.

[0008] Preferably, the inner diameters at both ends of the through hole are larger than the inner diameter at the middle thereof, and both ends of the through hole are sleeve-matched with the annular body.

[0009] Preferably, the length of the spring is greater than the length of the through hole.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The track body involved in the present invention is to flip the rotating plate so that the outer side surface of the rotating plate is fitted with the upper surface of the track mounting base, and then the bolt is passed through the annular body and the spring and screwed into the mounting threaded hole, and the bolt is tightened. The bolt compresses the spring through the annular body, so that the track body is conveniently fixed and installed on the base; then the connecting head on the adjacent track body is clamped in the connecting groove set on the installed track body in the vertical direction, and the cross-section enlarged end is clamped and matched with the interface enlarged groove, so that the two track bodies complete the connection of the end heads. The whole installation process does not require the use of additional fasteners, which greatly facilitates the efficient installation of the track monomer.

[0012] 2. The present invention relates to a track body in which side guard plates extending vertically upward are respectively arranged on the front and back sides. When the running wheels of the crane run on the track surface at the top of the track body, the side guard plates on both sides prevent the running wheels from derailing from the track surface.
