Abstract
The invention relates to a horizontal prestress structural crane beam, which is provided with a beam body and is 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 invention relates to a horizontal prestressed reinforcement type crane beam.
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.
Disclosure of Invention
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 invention 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 invention has the following beneficial effects:
1, 2 or a plurality of first transversely arranged prestressed structures are arranged below the bottom of a beam body of the crossbeam; 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. According to the invention, the prestress structure is arranged below the bottom of the beam body, so that the strength of the beam body can be effectively improved, when the span of the beam is increased, the longitudinal section of the beam does not need to be increased, the beam body can still meet the strength requirement, the beam is convenient to reform, and the cost is effectively reduced.
The inner sides of two ends of the lower part of the beam body of the crossbeam are provided with first reinforcing plates, and the first reinforcing plates are welded and fixed with the lower part of the beam body of the crossbeam; 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. According to the invention, through the fixing structure, the connection reliability of the prestress structure and the beam body of the cross beam is ensured, and the strength of the beam body of the cross beam is further effectively ensured.
In the invention, 1, 2 or more transversely arranged second prestressed structures are arranged at the inner side of the beam body corresponding 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. According to the invention, the second prestress structure is arranged above the bottom of the beam body, so that the strength of the beam body is further effectively improved.

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.
