Summary of the invention:
The purpose of this invention is to provide the suspender that a kind of mode of utilizing buffering to clamp solves the coil of strip damage problem with steel-reel damage-proof function.
Suspender with steel-reel damage-proof function proposed by the invention comprises the hanging element that can be connected with the suspension hook of elevator or hoisting crane and is installed in the holder arms of hanging element lower area, be equipped with in the described holder arms and can and be installed in the elastic parts of this vertical axis inboard, spring also is installed on vertical axis and protrudes from the sliding part of holder arms medial surface by the outside face of this spring push along the vertical axis that moves radially of holder arms.
The two ends up and down of described vertical axis are respectively arranged with a radial direction through hole, and described elastic parts comprises the radial axle in the radial direction through hole that can extend into vertical axis and is enclosed within the spring of radial axle outside face.In the described holder arms and away from a side of vertical axis the limit switch that is triggered by vertical axis is installed also.
The both sides of described holder arms bottom are separately installed with the track adjusting wheel that is used to protect coil of strip, and the external diameter of this track adjusting wheel is lower than the upper surface of holder arms hook.
Suspender with steel-reel damage-proof function proposed by the invention increases in holder arms to be had by elastic parts and the spacing sliding part of vertical axis, this sliding part be subjected to external force do the time spent can along holder arms radially or move axially, when sliding part when moving radially, the application force that is produced between holder arms and the coil of strip end face can little by little be increased, thereby the ascending application force that gradually changes is imposed on the scraggly end face of coil of strip, and by gradually the extruding mode it is flattened, make the end face of coil of strip when maintenance is smooth, can not cause any infringement, and in suspender is sling the process that coil of strip rises, sliding part on the holder arms and coil of strip direct contact, and sliding part can move up and down, make between the two and change static relatively soft contact into, thereby can avoid the coil of strip end face to scratch effectively by moving contact; Simultaneously, owing in the hook both sides of holder arms bottom track adjusting wheel is installed, when suspender descended, track adjusting wheel can be rolled at the coil of strip end face, makes between the two to become rolling friction by sliding friction, thereby can avoid coil of strip to be scratched.
Description of drawings:
Accompanying drawing 1 is the outward appearance cut-away section structural representation of an embodiment of suspender proposed by the invention;
Accompanying drawing 2 is enlarged drawings of I part in the library.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the overall appearance structure of an embodiment of the suspender with steel-reel damage-proof function proposed by the invention.This suspender comprises hanging element 1 and holder arms 2, and the track adjusting wheel 3 that is installed in holder arms 2 lower ends.Wherein, hanging element 1 comprises suspension ring 11 that can be connected with the suspension hook of elevator or hoisting crane and the cantilever 12 that is installed in suspension ring 11 belows, the electrical components (because of belonging to prior art, not providing concrete structure among the figure) that is used to control holder arms 2 actions is installed in cantilever 12.
