Heavy-load type beam lifting appliance
Technical Field
The invention relates to the technical field of lifting appliances, in particular to a heavy-load type beam lifting appliance.
Background
The existing beam hanger comprises a main beam and beams fixedly arranged at two ends of the main beam, and the beams are generally connected with a workpiece to be lifted through a lifting belt, a chain or a steel rope. When the workpiece to be hoisted is large in mass, a common hoisting belt, a chain or a steel rope is difficult to bear, steel hangers are required to be additionally arranged at two ends of the beam, and the steel hangers are connected with lifting lugs arranged on the workpiece to be hoisted through pins. However, the positions of the steel pin holes and the pin holes of the lifting lugs are fixed, and the pin holes of the steel hanging bracket and the pin holes of the lifting lugs are not easy to align due to the fact that a workpiece to be processed is not placed in place or the lifting lugs are not installed in place, so that time is consumed for connecting the steel hanging bracket and the lifting lugs.
Disclosure of Invention
The invention provides a heavy-load beam hanger which can solve the technical problem that pin holes of a hanger and pin holes of lifting lugs are not easy to align in the using process of the beam hanger.
Its technical scheme is such, a heavy load type crossbeam hoist, includes girder, crossbeam and gallows, the crossbeam is installed respectively at the both ends of girder, gallows, its characterized in that are installed respectively at the both ends of crossbeam: the hanging bracket comprises an upper hinged hanging bracket and a lower hinged hanging bracket, the upper end of the upper hinged hanging bracket is in rotating fit with the end part of the cross beam, the lower end of the upper hinged hanging bracket is in rotating fit with the upper end of the lower hinged hanging bracket, and the lower end of the lower hinged hanging bracket is provided with a pin hole.
Furthermore, the main beam and the pair of cross beams are distributed in an I shape.
Furthermore, the upper portion of the upper hinged hanger is provided with an upper hinged groove, the lower portion of the upper hinged hanger is provided with a lower hinged groove, the end portion of the beam is provided with a connecting plate extending downwards, the connecting plate is in running fit with the upper hinged hanger through an upper rotating shaft after being inserted into the upper hinged groove, the lower hinged hanger is in running fit with the upper hinged hanger through a lower rotating shaft after being inserted into the lower hinged groove, and the axis of the upper rotating shaft is perpendicular to the axis of the lower rotating shaft.
Furthermore, the inner side walls of the upper hinge groove and the lower hinge groove and the two side walls of the connecting plate are respectively provided with a base plate.
According to the heavy-load beam hanger, when the position deviation exists between the pin hole of the lower hinged hanger and the pin hole of the lifting lug, the position deviation is eliminated through rotation between the lower hinged hanger and the upper hinged hanger, between the upper hinged hanger and the beam and between the beam and the main beam, rapid alignment of the lower hinged hanger and the upper hinged hanger is achieved, and the lifting efficiency is improved.

Detailed Description
As shown in fig. 1 to 3, a heavy-duty beam hanger comprises a main beam 1, beams 2 and hangers 3, the beams 2 are respectively installed at two ends of the main beam 1, the main beam 1 and a pair of beams 2 are distributed in an i-shaped manner, the beams 2 at the front side are fixedly connected with the main beam 1, the beams 2 at the rear side are connected with a support through the middle part thereof, a rotating shaft 6 is in running fit with the main beam 1, the hangers 3 are respectively installed at two ends of the beam 2, each hanger 3 comprises an upper hinged hanger 3a and a lower hinged hanger 3b, the upper end of the upper hinged hanger 3a is in running fit with the end part of the beam 2, the lower end of the upper hinged hanger is in running fit with the upper end of the lower hinged hanger 3b, and the lower end of the lower hinged hanger 3b is provided with a pin hole 5.
The upper portion of the upper hinge hanger 3a is provided with an upper hinge groove, the lower portion of the upper hinge hanger is provided with a lower hinge groove, specifically, the upper hinge groove is formed by a space between a pair of upper hinge plates 31 which are arranged in parallel, the lower hinge groove is formed by a space between a pair of lower hinge plates 32 which are arranged in parallel, the pair of lower hinge plates 32 are arranged between the pair of upper hinge plates 31 and are mutually perpendicular and fixedly connected, a connecting plate 4 which extends downwards is installed at the end portion of the cross beam 2, the connecting plate 4 is in running fit with the upper hinge hanger 3a through an upper rotating shaft 3d after being inserted into the upper hinge groove, the lower hinge hanger 3b is in running fit with the upper hinge hanger 3a through a lower rotating shaft 3c after being inserted into the lower hinge groove, and the axis of the upper rotating shaft 3d is mutually perpendicular to the axis of the lower rotating shaft 3 c.
Go up the inside wall in hinge groove and lower hinge groove to and the both sides wall of connecting plate 4 is equipped with the backing plate respectively, through the setting adjustment connecting plate 4 of backing plate and last hinge groove between clearance and hinge groove and hinge gallows down between the clearance, prevent to rock, improve the stability of articulated department.
