The crane rail is of self-evident importance as a load-bearing part for the crane weight and its load. At present, the fixed knot of portal crane rail constructs to be: pressing plates are arranged on two sides of the lower portion of the steel rail and welded on the embedded steel plates, the embedded steel plates are arranged on the track beam, two steel plates need to be embedded at one fixed point, the pressing plates need to be welded on site, construction workload is large, and construction progress is slow; the fixing structure has no adjustability and no assembly; the anti-roll stability is poor, the deformation and the looseness are easy, and great hidden danger exists for the safety.
SUMMERY OF THE UTILITY MODEL
The utility model provides a structure for quickly fixing the steel rail of the gantry crane, which has good stability, safety and reliability; can be adjusted and is convenient to construct.
The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a structure for portal crane rail is fixed fast, includes the clamp plate that sets up in rail lower part both sides, its characterized in that, be located two of same fixed point both sides the clamp plate adopts the nut lock solid respectively on two bolt portions of a U type bolt, U type bolt is pre-buried in the track roof beam.
And an inclined plane which is pressed with the lower part of the steel rail is arranged on the inner side of the lower part of the pressing plate.
The pressing plate is provided with a waist-shaped connecting hole, and the length direction of the waist-shaped connecting hole is vertical to the length direction of the steel rail.
The utility model has the advantages and positive effects that: the U-shaped bolts embedded in the track beam are used for locking and fixing the structure of the pressing plates positioned on two sides of the steel rail, the U-shaped bolts provide stable anti-overturning moment for the steel rail, the anti-tilting stability of the steel rail can be greatly improved, and the structure is safe and reliable. The steel rail can be quickly reinforced after the track beam is paved; the structure that the waist-shaped connecting hole and the pressing and fixing inclined plane are arranged on the pressing plate is adopted, so that the installation and adjustment are convenient, the assembly is convenient, the construction efficiency can be improved, and the construction period can be shortened; the pressing plate with one size can adapt to different steel rail models, and is wide in application range and strong in popularization.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of fig. 1.
In the figure: 1. a steel rail; 2. a track beam; 3. a U-shaped bolt; 4. pressing a plate; 5. a nut; 6. waist-shaped connecting holes.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:
referring to fig. 1 and 2, the structure for quickly fixing the steel rail of the gantry crane comprises pressing plates 4 arranged on two sides of the lower portion of the steel rail 1, wherein the two pressing plates 4 positioned on two sides of the same fixed point are respectively locked on two bolt portions of a U-shaped bolt 3 through nuts 5, and the U-shaped bolt 3 is embedded in a track beam 2. The U-shaped bolts 3 pre-buried in the track beam 2 are adopted to lock and fix the structure of the pressing plates 4 on two sides of the steel rail 1, the U-shaped bolts 3 provide stable anti-overturning moment for meeting the steel rail, the anti-tilting stability of the steel rail can be greatly improved, the installation is convenient, and the construction efficiency can be improved.
In this embodiment, the inner side of the lower portion of the pressing plate 4 is provided with an inclined surface which is in press fit with the lower portion of the steel rail 1, the pressing plate 4 adopts the inclined surface to press and fix the steel rail 1, the anti-roll stability of the steel rail can be further improved, and meanwhile, one inclined surface can adapt to different steel rail models, so that the application range can be expanded. The pressing plate 4 is provided with the waist-shaped connecting hole 6, the length direction of the waist-shaped connecting hole 6 is perpendicular to that of the steel rail 1, the position of the pressing plate 4 can be conveniently adjusted during installation, assembly is convenient, and the construction speed can be accelerated.
The utility model discloses a construction method:
1) ligature track roof beam reinforcing bar for the steadiness of strengthening the track roof beam, generally take track roof beam reinforcing bar and hat roof beam pre-buried steel sheet to weld or carry out the bar planting with retaining wall and be connected, will guarantee the reinforcing bar anchor length of roof beam and wall simultaneously.
2) And (5) erecting a template.
3) U-shaped bolts 3 are pre-embedded, and are arranged at intervals of a set length in the longitudinal direction of the track beam, so that the distance between two screw parts of the U-shaped bolts and the steel rail are equal. Compared with a fixed point, the U-shaped bolt has the advantages of convenient construction and excellent stress.
4) And concrete is poured, so that the flatness and the pouring quality of the concrete surface at the exposed positions of the two bolt parts of the U-shaped bolt are ensured, and the phenomenon that the periphery is gapped and loosened is avoided.
5) Laying the steel rail 1, installing the pressing plate 4, and then locking and reinforcing. The steel rail 1 is placed horizontally, and when the steel rail can not be in complete contact with the concrete on the top surface of the track beam or a gap exists, other thin steel plates and the like are adopted for lower cushions, so that the stress of the steel rail is uniform. The pressing plates 4 are symmetrically arranged on two sides of the steel rail and have the same distance with the edge of the steel rail.
6) Other description items
In the structure, two bolt parts of each U-shaped bolt are reinforced by adopting 2 nuts, so that the tightness of the U-shaped bolt is ensured. Meanwhile, a gasket is arranged under the nut, so that the stress of each part is uniform and symmetrical. And because the pressing plate is pressed and fixed by adopting the inclined surface, the steel rail can be adjusted according to different types of steel rails, and the requirements of firm adhesion and stress can be met.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
