Embodiment Construction

[0011] from figure 1 , figure 2 It can be seen that the lifting electromagnet of the present invention is a "U"-shaped or "E" electromagnet, and the present invention is preferably an "E" electromagnet, the length of each magnetic pole 8 is 1800mm, and the bottom surface can be either a plane , can also have a through slot 9 in the length direction of the bottom surface, the present invention preferably has a through slot 9 in the length direction of the bottom surface of the magnetic pole 8, the through slot 9 is trapezoidal, the height is 10mm, the upper width is 32mm, the lower width is 40mm, the through slot There are 20 vertical cavities 3 evenly distributed on the center line of 9. The cavities 3 run through the bottom of the magnetic pole 8. The cavity 3 is equipped with a guide column 2 with a "T"-shaped longitudinal section. After a guide column 2, a baffle plate 4 with a hole is installed at its bottom, so that the lower end of the guide column 2 protrudes from the...

Abstract

The invention discloses a hoisting electromagnet, especially a hoisting electromagnet for hoisting a long product with a circular section. The hoisting electromagnet is U-shaped or E-shaped, at leastone vertical cavity is arranged in each magnetic pole along the length direction, each cavity is provided with a guide post capable of moving upward and downward in the cavity; a magnetoconductive flexible metal tape is arranged on the bottom of each magnetic pole along the length direction, two ends of the flexible metal tape fixedly connect with two ends of the magnetic pole bottom along the length direction respectively, the central upsides of the segments of the flexible metal tape fixedly connect with bottoms of corresponding guide posts respectively according to length ratio, two ends ofthe magnetic pole bottom along the length direction are fixedly connected by a short flexible metal tape respectively, the upper end of the short flexible metal tape is fixed and the lower end of theshort flexible metal tape droops freely. The invention can hoist steel pipe safely and reliably, and has a simple structure.

Description

technical field [0001] The present invention relates to a hoisting electromagnet, in particular to a hoisting electromagnet for hoisting and transporting circular section long materials, such as a hoisting electromagnet for hoisting steel pipes, round billets and round bars. Background technique [0002] For the lifting and transportation of steel pipes by steel pipe manufacturers, whether it is a single steel pipe or a plurality of steel pipes, steel wire ropes are generally used for hanging and transporting, and the work efficiency is low; There are generally two types, one is a lifting electromagnet with a movable magnetic pole, and the other is a lifting electromagnet without a movable magnetic pole. The hoisting electromagnet without a movable magnetic pole has a plurality of arc teeth on the magnetic pole surface, which can better envelop the steel pipe of a certain specification, thereby increasing the contact between the steel pipe and the magnetic pole, which is ben...
