In engineering, crane rail clip is an engineering field between mechanical and civil engineering. The railway installation is usually installed on the side of the factory building. The crane is installed in the unit of the crane, and the two are often disconnected. The installation of rail beams in construction and the installation of crane rails are usually two major (such as civil and mechanical installation) and the gap between the two majors. Therefore, it is difficult to obtain real guarantee for the quality of crane rail installation. Crane rail installation directly affects the crane operation quality.
Only when the quality control is mastered from the source, can the crane rail installation quality be guaranteed. There are two kinds of rail beams for installation guide rails: one is steel girder and the other is precast concrete beam.
Precast concrete beams must have mounting bolts embedded in holes, or concrete prefabricated beams embedded in bolts. The installation method of crane rail clip is very important for fixing plate, hook screw, welding and bolt. In order to adjust the horizontal direction, the holes in the track plate are usually large holes, and the vertical adjustment can be filled under the guide rail. When the guide plate is designed, it should have sufficient rigidity, each plate, according to the force of size can be made into a single hole or two holes.
Only when the rail pressure plate is connected to the fixed steel plate of the track beam or rail beam, the gears can be welded to the track. Before the height of the seat cushion, according to the variety, length and fixed condition of the rail and the surrounding factors such as temperature, before using, with copper and carbon steel sheet will be the end of the guide rail 30 ~ 40 mm, use connector, such as the assembly good bolt and plate, screw the nut, the guide rail is fixed on the rail beam, set up in each at least four fixed point near the rail joint. When the bottom of the welding track, loosen the plate, the guide rail end of the liner part of the lower to 20mm, and then tighten the plate nut. When welding the waist part of the rail, gradually reduce the height of the cushion layer, when the waist part of the welding, should remove all of the gasket, and loosen the plate, the value of the rail joint on the welded rails at this time should be very small.
According to the rail, decide whether to tighten the plate nut. During the welding process, the deformation of the rail joint must be checked at any time by the straight steel ruler, and the height of the joint and the thickness of the loose plate shall be adjusted to control the deformation of the rail joint. When the rail joint is fixed before welding, the gap between the 2 rail ends is narrower than the width, and the gap between the rails is not less than 12mm, and it should not be too wide, generally within 15 ~ 18 mm range. When adjusting the fixed guide joint, the 2 rail end must be aligned in addition to ensuring the end gap size, and cannot be distorted and staggered.
