Embodiment Construction
[0033] The present invention is described in further detail below in conjunction with accompanying drawing:
[0034] figure 1 It is a schematic diagram of the overall structure of the present invention, including a base 1 and a lifting bracket 2; a number of rollers 5 are arranged between the base 1 and the lifting bracket 2, and the rollers 5 can adopt round steel whose outer surface is wound with wear-resistant adhesive tape. When the surface of the seat is rolling, it can protect the surface of the base from mechanical damage; copper rods can also be used, the material is soft and will not damage the surface of the base. Such as image 3 , the roller 5 can also adopt the following structure: a screw hole 16 is set on the end face, and the screw hole 16 is connected with a screw rod 17, and the screw rod 17 is connected with a limiting circular plate 15, and the limiting circular plate 15 can be fixed with the screw rod 17 by welding, or it can be fixed in a limited positio...

The invention discloses a lifting device and a steel beam continuous lifting method based on the same, and belongs to the technical field of lifting devices and lifting processes. A fixed base and a movable lifting bracket are adopted to perform a lifting operation; a windlass and a pulley are fixed on the lifting bracket; when the lifting bracket horizontally moves through a roller, the lifting bracket can move above objects to be lifted; after the objects are lifted by using a lifting tool, the objects are shifted to a preset position through the lifting bracket; and through a limiting hoop,the lifting bracket only can perform a linear reciprocating motion along the base, so that the overturning of the lifting brackets due to higher weight of the lifted objects or accidents caused by other displacements can be prevented. The device is simple in structure and convenient to use, greatly reduces the crane occupied working surface, is free of influencing normal construction of other work under a steel roof truss, and meanwhile, reduces the crane construction safety risk. The method is convenient to operate and high in safety.
Description
technical field [0001] The invention belongs to the technical field of hoisting devices and hoisting techniques, and in particular relates to a hoisting device and a continuous hoisting method for steel beams based on the hoisting device. Background technique [0002] At present, during the construction of steel structure houses, the roof steel girders are lifted by traditional cranes, which not only occupies a large working area, but also has low work efficiency, and is prone to safety risks of collapse due to uneven force. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a hoisting device and a continuous hoisting method for steel beams based on it, which is achieved through the following technical solutions: [0004] The invention discloses a hoisting device, which comprises a base and a lifting bracket; a number of rollers are arranged between the base and the lifting bracket, and the lifting bra...
