Embodiment Construction

[0019] Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Take a group of seven 100m rails 4 as an example: Figure 1 to Figure 3 As shown, a kind of rail anti-falling device 1 for electromagnetic crane of the present invention comprises fixed frame 1.1 and eight booms 1.2, the upper end of fixed frame 1.1 is connected with electromagnetic crane, and the middle part of fixed frame 1.1 is provided with lifting mechanism 1.4 . A rack is provided on the side of the fixed frame 1.1, and the output gear of the lifting mechanism 1.4 is engaged with the rack, so that it can move vertically along the fixed frame 1.1. Eight suspenders 1.2 promptly are arranged on this elevating mechanism 1.4, thereby can move vertically under the drive of elevating mechanism 1.4. The lifting mechanism 1.4 is provided with a traversing mechanism 1.3, and the traversing mechanism 1.3 is also connected with eigh...

Abstract

The invention discloses a steel rail anti-fall device used for an electromagnetic crane, and relates to equipment used in the processes such as conveying, loading, transporting and the like of a steel rail. The device comprises a fixed frame connected with the electromagnetic crane and a suspender used for locking the steel rail, wherein the fixed frame is also provided with a lifting mechanism which is used for driving the suspender to move longitudinally; the lifting mechanism is provided with a transversely moving mechanism which is used for driving the suspender to move transversely; and the lifting mechanism is also provided with a steering mechanism used for driving the suspender to rotate. Further, the transversely moving mechanism is provided with a grating ranging positioner used for positioning the relative position between the suspender and the steel rail. In the device, the arrangement of the grating ranging positioner in the transversely moving mechanism makes the suspender in the device perform fine adjustment accurately; combining lifting and rotating actions of the suspender, the suspended steel rail can be locked effectively so as to prevent the steel rail from falling; and the lower end of the suspender has an inverted T shape and is in clearance fit with an adjacent steel rail. Therefore, the suspender is not only convenient to exert, but also not easy to cause the abrasion of the suspender and the steel rail.

Description

technical field [0001] The invention relates to the equipment used in the process of rail handling, loading and reversing operations, etc., in particular to a rail drop prevention device for an electromagnetic crane. Background technique [0002] During the lifting process of steel rails (especially long heavy rails), two electromagnetic cranes are often required to operate at the same time. After the power is turned on, the electromagnet of the electromagnetic crane firmly attracts the rail to realize lifting; when the power is cut off, the magnetism of the electromagnet disappears, and the rail is put down. During the above process, if the electromagnetic crane is operated carelessly, or due to sudden power failure and other reasons, the 100-meter-long steel rail may fall from a high altitude, causing heavy property losses and personal casualties. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rail drop-pre...
