[0001] The utility model relates to the technical field of electromechanical equipment installation, and relates to a track adjusting device, in particular to a track adjusting device with simple operation and capable of greatly improving the track adjusting efficiency. Background Technique

[0002] A bridge crane is a hoisting equipment that spans over workshops, warehouses, and material yards for material hoisting. Its two ends are located on the crane girders of steel structure columns. The bridge of the bridge crane runs longitudinally along the tracks laid on the two-sided crane girders above, and can utilize the space under the bridge for hoisting materials without being hindered by ground equipment. It is a kind of hoisting machinery and equipment with the widest use range and the largest number, and is widely applicable to indoor and outdoor warehouses, factories, docks, open storage yards, etc.

[0003] The crane girder is a structure that supports the operation of the bridge crane. Tracks are installed on the crane girder, and the bridge crane travels back and forth on the crane girder through the tracks. Due to the characteristics of short construction time, low cost, and convenient loading and unloading of steel structure crane girders, steel structure crane girders have been widely used in China in the past few decades.

[0004] For the installation and adjustment of the traveling track of the bridge crane, after placing the track on the steel structure crane girder and adjusting the elevation and center line deviation, a rail clip is installed to fix the track. The steps of the currently commonly used track adjustment method are as follows: 1) Weld a track adjustment bolt adjusting substrate on the crane girder. The track adjustment bolt adjusting substrate is perpendicular to the crane girder, and a threaded hole is opened on the track adjustment bolt adjusting substrate, and an adjustment bolt is threadedly connected at the threaded hole; 2) Rotate the adjustment bolt to top the track to the position required by the installation specification; 3) Install the rail clip and tighten the rail clip bolt; 4) Cut the track adjustment bolt adjusting substrate and polish it flat; 5) Repair the primer and topcoat at the position where the track adjustment bolt adjusting substrate is welded on the crane girder. The above method is cumbersome to operate, requires welding and cutting of the track adjustment bolt adjusting substrate, and has low operation efficiency.

[0015] (4) Install the rail clip and tighten the rail clip bolt.

[0016] (5) Loosen the fixator fixing bolt and remove the track adjustment device.

[0017] As a preferred technical solution:

[0018] For a track adjustment device as described above, the connecting plate is perpendicular to the clamping plate.

[0019] For a track adjustment device as described above, the track adjustment bolt adjusting substrate is fixedly welded to the clamping plate with the screw hole II.
