Description

Technical Field

[0001] The present invention belongs to the technical field of hoisting equipment installation, and particularly relates to a large gantry crane load test device. Background Art

[0002] During the large gantry crane load test, steel bars are generally selected as the test load (the construction industry uses a large amount of steel bars, and the steel bars can still be used after the gantry crane load test, saving costs and facilitating counterweight at the same time). Usually, a temporary hoisting platform is made, and the steel bars are stacked on the platform during the test. The platform is connected to the large hook of the gantry crane through a steel wire rope. The gantry crane load test is carried out many times. Each time the load is increased (or decreased), the steel wire rope needs to be removed, and after the load is added, the steel wire rope needs to be restored, and then the test is carried out. The conventional load test process is cumbersome and the work efficiency is low. As the load gradually increases, the steel wire rope is prone to rubbing against the steel bars, posing a safety hazard. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the traditional large gantry crane load test process is cumbersome, has low efficiency and poses a safety hazard.

[0004] To solve the above technical problem, the present invention provides a large gantry crane load test device, including: a box girder, a lifting lug plate, a reinforcing plate, a lifting lug plate reinforcing member, a plurality of platforms, two support members, a plurality of inclined supports, a plurality of side blocks, a shaft pin, a reinforcing rib; the two reinforcing plates are fixedly connected to both sides of the box girder, the two lifting lug plates are respectively fixedly connected to the box girder, the reinforcing rib is further connected to the reinforcing plate and the box girder, and there is a lifting hook between the two lifting lug plates and is fixed by a shaft pin; one end of the lifting lug plate reinforcing member is respectively fixedly connected to the left and right sides of the lifting lug plate, and the other end is fixedly connected to the box girder. The plurality of platforms are evenly distributed and fixed on the upper surface of the box girder. At both ends of each platform, there are side blocks vertically connected to the platform. There is an inclined support fixedly connected between the lower surface of the platform and the box girder. A support member is connected at the connection between the inclined support and the platform, and the support member is supported by a steel pier.

[0005] Further, the platform is composed of ten I-beams, and the ten I-beams are arranged at equal intervals. <G

[0006] Further, the support member is of an I-shaped structure.

[0007] Further, the included angle between the inclined support and the platform is 45 degrees.

[0008] Further, the included angle between the lifting lug plate reinforcing member and the platform is 60 degrees.

[0009] Advantages of the present invention: A large bridge crane load test tool of the present invention has a simple structure, is easy to manufacture, and can be reused. A platform is horizontally laid on the box girder with I-beams, and the I-beams are welded and fixed to the box girder. Side blocks are welded at both ends of the I-beams, which is beneficial for stacking steel bars and preventing them from slipping, can well protect the steel bars from deformation, and is safe and reliable at the same time.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] Such as Figures 1-3As shown, a large bridge crane load test device includes: a box beam 1 (a steel plate with a length of 10m, a width of 1m, a height of 1.5m, and a thickness of 20mm), a lug plate 2, a reinforcement plate 3, a lug plate reinforcement 4, several platforms 5 (I63 I-steel), several supports 6 (I28 I-steel), several oblique supports 7, several side guards 8 (16 channel steel), axle pins 9, and reinforcement ribs 10; the two reinforcement plates 3 are fixedly connected to both sides of the box beam 1, the two lug plates 2 are fixedly connected to the box beam 1 and the reinforcement ribs 10 respectively, and the reinforcement The ribs 10 are respectively connected to the reinforcing plate 3 and the box beam 1. There is a hook 11 in the middle of the two ear plates 2 and it is fixed by an axle pin 9. One end of the ear plate reinforcement 4 is respectively fixedly connected to the left and right sides of the ear plate 2, and the other end is fixedly connected to the box beam 1. The platforms 5 are evenly distributed and fixed on the upper surface of the box beam 1. Each platform 5 has side guards 8 at both ends vertically connected to the platform 5. The bottom of the platform 5 is fixedly connected to the box beam 1 with an oblique support 7. The connection between the oblique support 7 and the platform 5 is connected to a support member 6, and the support member 6 is supported by a steel pier 12.
