Description
Technical Field
The utility model relates to a lifting device field specifically is a orbital connecting device of hoist I-steel.
Background
When high-rise and super high-rise building construction, each facade of building all has the perpendicular handling, the demand of transporting on the same floor or cross-layer level from the first floor to the top layer, through arranging the I-steel track at the high-rise outdoor, installs the middle-size and small-size hoist of walking, the transportation installation that realizes the article that can be quick has higher work efficiency than the construction tower crane. However, when the traditional I-steel rail is erected, the I-steel or the steel structure which is cantilevered is welded with the I-steel rail, so that the mounting difficulty is high, the workload is high, destructive cutting is needed during disassembly, and the material cannot be reused.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide an install swift and repeatedly usable's orbital connecting device of hoist I-steel.
In order to achieve the above object, the present invention is realized as follows:
a connecting device for an I-steel rail of a crane comprises a front clamp, a rear clamp and a fastening bolt; the front clamp and the rear clamp are made of steel plates through welding, the front clamp and the rear clamp are sleeved on the cantilever steel beam, the track I-shaped steel beam is clamped by the front clamp and the rear clamp to be connected to the cantilever steel beam after the upper flange is clamped, the front clamp and the rear clamp are fastened with the cantilever steel beam through bolts, and the front clamp and the rear clamp are connected and fastened through bolts arranged on rib plates of the clamps.
The steel beam for cantilever is specifically an I-steel cantilever from indoor to outdoor.
The connecting device has reasonable and reliable structure stress, does not need welding connection during site construction, has large adjusting range, only carries out bolt tightening operation through a simple wrench, and can also be disassembled through the simple wrench after the construction is finished. So, through simple construction operation, can realize girder steel track arrangement operation on a large scale.
Drawings
Fig. 1 is a first schematic structural diagram of the connecting device.
Fig. 2 is a second schematic structural diagram of the present connecting device.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a connecting device for an i-steel rail of a crane comprises a front clamp, a rear clamp and a fastening bolt; 1I-shaped steel beam for overhanging is connected with a 20I-shaped steel beam as a track construction through a front clamp and a rear clamp. In the installation process, the 16# I-shaped steel beam 3 is connected and fixed with a structural beam or a floor, the clamp 1 and the clamp 2 are sleeved at the front end of the 16# I-shaped steel beam 3, and then the upper flange of the I-shaped steel beam 4 is clamped in a gap between the clamp 1, the clamp 2 and the lower flange of the I-shaped steel beam 3. After the installation position is adjusted, the bolts 6 are respectively fastened by using a wrench.
The width of the upper flange and the lower flange of the No. 16I-shaped steel beam 3 is 88mm, the clamp 1 and the clamp 2 are made of Q235B steel with the thickness of 12mm, and the clearance size inside the clamp is 90 mm. The thickness of the ribbed slab 5 for the clamp connecting bolt is 10mm, and the two sides of the ribbed slab are symmetrically arranged. The diameter of a fastening bolt between the clamp and the I-shaped steel beam 3 is M12, and the diameter of a bolt for connecting the clamp and the clamp through a ribbed plate is M10. The reinforcing rib plates 7 are symmetrically arranged on the clamp, and the thickness of the reinforcing rib plates is 8 mm.
Claims (2)
1. The utility model provides a connecting device of hoist I-steel track, characterized by: the clamp comprises a front clamp, a rear clamp and a fastening bolt; the front clamp and the rear clamp are made of steel plates through welding, the front clamp and the rear clamp are sleeved on the cantilever steel beam, the track I-shaped steel beam is clamped by the front clamp and the rear clamp to be connected to the cantilever steel beam after the upper flange is clamped, the front clamp and the rear clamp are fastened with the cantilever steel beam through bolts, and the front clamp and the rear clamp are connected and fastened through bolts arranged on rib plates of the clamps.
