Abstract
The utility model relates to a horizontal prestressing force structural formula hoist crossbeam has the crossbeam roof beam body, its characterized in that: 1, 2 or a plurality of first transversely arranged prestressed structures are arranged below the bottom of the beam body of the cross beam; and two ends of the first prestress structure are fixed with two ends of the bottom of the beam body of the cross beam.
Description
Technical Field
The utility model relates to a horizontal prestressing force strengthening rib formula hoist crossbeam.
Background
The crane is also called a traveling crane, a gantry crane and a crown block, and is indispensable hoisting equipment in factories. In use, the span of the crane beam cannot be too large, otherwise the beam is prone to bending. With the development of science and technology, the more the plant span is built, the more the span of the crane is required to be increased. The crane span increases, and the longitudinal section of crane crossbeam needs corresponding increase, guarantees crane crossbeam intensity. If the span of the cross beam is increased, the longitudinal section of the cross beam is not enlarged, the cross beam can sink when a heavy object is lifted by the crane, and the cross beam of the crane deforms or even breaks seriously.
SUMMERY OF THE UTILITY MODEL
The invention aims to provide a horizontal prestress structural crane beam, which can effectively improve the strength of the crane beam.
The technical scheme for realizing the purpose of the utility model is as follows:
the utility model provides a horizontal prestressing force structural formula hoist crossbeam, has the crossbeam roof beam body, its characterized in that: 1, 2 or a plurality of first transversely arranged prestressed structures are arranged below the bottom of the beam body of the cross beam; and two ends of the first prestress structure are fixed with two ends of the bottom of the beam body of the cross beam.
Furthermore, the inner sides of the two ends of the lower part of the beam body are provided with first reinforcing plates, and the first reinforcing plates are welded and fixed with the bottoms of the two ends of the lower part of the beam body; the two ends of the first prestress structure are fixed with the first reinforcing plate through a prestress tensioning device, and the first reinforcing plate is correspondingly provided with a connecting hole.
Furthermore, 1, 2 or more second prestressed structures which are transversely arranged are arranged on the inner side of the beam body and correspond to the upper part of the bottom of the beam body, and two ends of each second prestressed structure are fixed with two ends of the lower part of the beam body through prestressed tensioning devices; the inner sides of the two ends of the lower part of the beam body are provided with second reinforcing plates, and the second reinforcing plates are welded and fixed with the inner sides of the two ends of the lower part of the beam body; the two ends of the second prestress structure are fixed with the second reinforcing plate through a prestress tensioning device, and the second reinforcing plate is correspondingly provided with a connecting hole.
Further, the prestressed structure is a prestressed reinforcing rib.
Further, the prestress tension device is a tension bolt.
The utility model discloses beneficial effect who has:
the bottom of the beam body of the cross beam is provided with 1, 2 or a plurality of transversely arranged first prestressed structures; and two ends of the first prestress structure are respectively fixed with two ends of the bottom of the beam body of the cross beam through prestress tensioning devices. The utility model discloses a set up prestressing force structure in crossbeam roof beam body bottom below, can effectively improve the intensity of the crossbeam roof beam body, when increasing the crossbeam span, need not increase crossbeam longitudinal section, the crossbeam roof beam body still can satisfy the strength requirement, makes things convenient for the crossbeam to reform transform, effective reduce cost.
The first reinforcing plates are arranged at the inner sides of the two ends of the lower part of the beam body of the cross beam, and the first reinforcing plates are welded and fixed with the lower part of the beam body of the cross beam; the two ends of the first prestress structure are fixed with the first reinforcing plate through a prestress tensioning device, and the first reinforcing plate is correspondingly provided with a connecting hole. The utility model discloses an above-mentioned fixed knot constructs, has guaranteed the reliability of being connected of prestressed structure and the crossbeam roof beam body, and then effectively guarantees crossbeam roof beam body intensity.
The utility model discloses the internal side of crossbeam roof beam corresponds crossbeam roof beam body bottom top and is equipped with the second prestressed structure of 1, 2 or a plurality of horizontal settings, it is fixed that prestressing force straining device is passed through with crossbeam roof beam body lower part both ends in the both ends of second prestressed structure. The utility model discloses a set up second prestressed structure in crossbeam roof beam body bottom top, further effectively improve the intensity of the crossbeam roof beam body.

Detailed Description
The first embodiment is as follows:
as shown in fig. 1, 1 first prestressed structure 3 arranged transversely is arranged below the bottom of the beam body 1. In this embodiment, the first prestressed structure 3 is a prestressed reinforcing rib. Two ends of the first prestress structure 3 are fixed with two ends of the bottom of the beam body 1 through prestress tensioning devices. In this embodiment, the prestress tensioner uses the tension bolt 2. The inner sides of the two ends of the lower part of the beam body 1 are provided with first reinforcing plates 4, and the first reinforcing plates 4 are welded and fixed with the bottoms of the two ends of the lower part of the beam body 1; the two ends of the first prestressed structure 3 are fixed with the first reinforcing plate 4 through the tensioning bolts 2, and the first reinforcing plate 4 is correspondingly provided with a connecting hole.
Example two:
the difference between the second embodiment and the first embodiment is that 1 second prestressed structure 5 arranged transversely is arranged on the inner side of the beam body corresponding to the upper part of the bottom of the beam body, and the second prestressed structure 5 is a prestressed reinforcing rib. And two ends of the second prestressed structure 5 are fixed with two ends of the lower part of the beam body of the cross beam through prestressed tensioning bolts. When the beam is implemented, the inner sides of the two ends of the lower part of the beam body are provided with second reinforcing plates 6, and the second reinforcing plates 6 are fixedly welded with the inner sides of the two ends of the lower part of the beam body; the two ends of the second prestressed structure 5 are fixed with the second reinforcing plate 6 through tensioning bolts, and the second reinforcing plate 6 is correspondingly provided with connecting holes.
