Crane runway mounting device and method

Abstract

The invention discloses a crane runway mounting device. The crane runway mounting device comprises embedded bolts, level adjusting nuts, a threaded base plate, perpendicularity adjusting bolts, base plates, pressure plates, wedge-shaped base plates and hold-down nuts, wherein the level adjusting nuts are screwed at the lower parts of the embedded bolts; the threaded base plate is U-shaped and comprises side plates on two sides and a flat plate in the middle; threaded holes are formed in each side plate; the perpendicularity adjusting bolts are screwed in the threaded holes; through holes corresponding to the embedded bolts are formed in the flat plate; slotted holes matched with the embedded bolts are formed in the base plates flatly placed between the bottom outer edge of a track and theside plates of the threaded base plate; the perpendicularity adjusting bolts prop against side surfaces of the base plates; the through holes matched with the embedded bolts are formed in the pressureplates placed on the base plates and the bottom of the track; through holes corresponding to the embedded bolts are formed in the wedge-shaped base plates placed on the pressure plates; and the hold-down nuts are screwed at the upper parts of the embedded bolts. Besides, the invention further discloses a crane runway mounting method which employs the mounting device. According to the crane runwaymounting device and method, the track can be adjusted according to thread levels, and the demand on the track mounting accuracy of a conventional full-automatic crane is met.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a crane rail installation device and an installation method. Background technique [0002] The existing installation device of the crane track mainly includes parts such as the base, the pressure plate, the adjustment plate, the gasket, the bolt, etc. The installation method of using the installation device to install the crane track is basically: Arrange pressure plates on both sides to position the bottom plate, and then weld it. It is required that medium-duty cranes use two-sided welding, and heavy-duty cranes use welds on three sides. The quality of the welds should meet the appearance quality standards of the third-level welds; Adjust the track at both ends of the crowbar first and then the middle to the required value and then fix it, then use the disc ruler to adjust the track on the other side according to the gauge value, the method is the same; after the track is aligned, all the...
