The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the scheme drawing of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-2; A kind of elevator traction wheel brake locking hook of the present invention; Said traction sheave comprise tubular wheel body 1 and with the hollow tube-shape axle sleeve 3 of said wheel body 1 coaxial setting; Link to each other through four spokes 5 that circumferentially distribute perpendicular to said wheel body 1 between said wheel body 1 and the axle sleeve 3, said each spoke 5 is positioned at wheel body 1 axial centre plane.Said brake locking hook comprises direct rod shape body 2 and the magnetic hook-shaped head 4 of being located at said body 2 one ends; In the position-limiting drum that is plugged in an end opening 6 that said body 2 can move along the axis; Head 4 stretches out position-limiting drum 6 open ends; Afterbody is arranged on position-limiting drum 6 closing ends through a spring 8, and spring 8 axis overlap with said body 2 axis.The head 4 of said brake locking hook leaves a side of position-limiting drum 6 along position-limiting drum 6 axis bearing of trends, is provided with electromagnet 12.Said hook-shaped head 4 comprises the shaft-like connecting portion 41 and the shaft-like braking parts 42 that is parallel to said body 2 perpendicular to brake locking hook body 2; Wherein, Connecting portion 41 length are greater than wheel body 1 thickness, and braking parts 42 length are greater than the distance of spoke in the traction sheave 5 to the traction sheave end face.Arbitrary radial position place is provided with and is parallel to position-limiting drum 6 axially extended guide rails in the said position-limiting drum 6, and said direct rod shape body 2 movably is embedded in said guide rail.Said brake locking hook also comprises an abutment sleeve 14; Said abutment sleeve 14 bearing of trends are parallel to said position-limiting drum 6 axis, an end opening, and an end is closed; Open end and closing end direction are with position-limiting drum 6 two ends, and abutment sleeve 14 axis and said braking parts 42 kernel of section lines are positioned on the straight line.It is former when long that said spring 8 is in nature, and said braking parts 42 is plugged in the said abutment sleeve 14.Electromagnet 12 and abutment sleeve 14 along the length of position-limiting drum 6 axis directions greater than said traction sheave wheel body 1 thickness and said braking parts 42 length sums.When the head 4 of said brake locking hook body 2 was attracted to be close to electromagnet 12 by electromagnet 12, afterbody remained in the position-limiting drum 6.
The traction sheave that during installation the brake locking hook of present embodiment is fixed in axis horizontal is an end radially; Position-limiting drum 6 parallel axes in and highly equal the traction sheave axis, guide level is horizontally disposed with, abutment sleeve 14 lays respectively at the axial both sides of traction sheave with said braking parts 42; Extension spring 8; Make in the space of 3 on said braking parts 42 insertion traction sheave wheel bodys 1 and axle sleeve, promptly the working position 16, then remove the tensile force to spring 8; Make it be returned to natural length, braking parts 42 is inserted location in the abutment sleeve 14.During the traction sheave normal operation, also have magnetic attracting force through electric current in the electromagnet 12, hold said hook-shaped head 4 fast, braking parts 42 withdraws from abutment sleeve 14 and said working position 16, does not influence the traction sheave normal rotation.During emergency braking, cut off the electricity supply, electromagnet 12 loses the attractive force to head 4; The spring 8 that elongates shrinks, and drives said body 2 and on guide rail, moves to position-limiting drum 6 closing ends, simultaneously; Braking parts 42 is inserted said working position; And then insert abutment sleeve 14, and the rotation of traction sheave spoke 5 is braked 42 in portion and stops, and traction sheave integral body obtains braking.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm technical scope according to the claim scope.
