Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1-2, a kind of elevator traction sheave brake locking hook of the present invention, described traction sheave comprises tubular wheel body 1 and the hollow tube-shape axle sleeve 3 with the coaxial setting of described wheel body 1, between described wheel body 1 and axle sleeve 3, be connected by four spokes 5 that circumferentially distribute perpendicular to described wheel body 1, described each spoke 5 is positioned at wheel body 1 axial centre plane.Described brake locking hook comprises direct rod shape body 2 and is located at the magnetic hook-shaped head 4 of described body 2 one end, in the position-limiting drum that is plugged in an end opening 6 that described body 2 can move along axis, head 4 stretches out position-limiting drum 6 open ends, afterbody is arranged on position-limiting drum 6 closing ends by a spring 8, and spring 8 axis overlap with described body 2 axis.The head 4 of described brake locking hook, along position-limiting drum 6 Axis Extension directions, leaves a side of position-limiting drum 6, is provided with electromagnet 12.Described hook-shaped head 4 comprises the shaft-like connecting portion 41 and the shaft-like detent 42 that is parallel to described body 2 perpendicular to brake locking hook body 2, wherein, connecting portion 41 length are greater than wheel body 1 thickness, and detent 42 length are greater than the distance of spoke in traction sheave 5 to traction sheave end face.Interior arbitrary radial position place of described position-limiting drum 6 is provided with and is parallel to the axially extended guide rail of position-limiting drum 6, and described direct rod shape body 2 is movably embedded in described guide rail.Described brake locking hook also comprises an abutment sleeve 14, described abutment sleeve 14 bearing of trends are parallel to described position-limiting drum 6 axis, an end opening, one end closure, open end and closing end direction are with position-limiting drum 6 two ends, and abutment sleeve 14 axis and described detent 42 kernel of section lines are positioned on a straight line.Described spring 8 is in naturally former when long, and described detent 42 is plugged in described abutment sleeve 14.Electromagnet 12 is greater than described traction sheave wheel body 1 thickness and described detent 42 length sums with abutment sleeve 14 along the length of position-limiting drum 6 axis directions.When the head 4 of described brake locking hook body 2 is attracted to be close to electromagnet 12 by electromagnet 12, afterbody remains in position-limiting drum 6.
When installation, the brake locking hook of the present embodiment is fixed on to radially one end of traction sheave of axis horizontal, position-limiting drum 6 axis are parallel to and highly equal traction sheave axis, guide level is horizontally disposed with, abutment sleeve 14 and described detent 42 lay respectively at the axial both sides of traction sheave, extension spring 8, described detent 42 is inserted in the space between traction sheave wheel body 1 and axle sleeve 3, it is working position 16, then remove the tensile force to spring 8, make it be returned to natural length, detent 42 is inserted the interior location of abutment sleeve 14.When traction sheave is normally worked, in electromagnet 12, also have magnetic attracting force by electric current, hold fast described hook-shaped head 4, detent 42 exits abutment sleeve 14 and described working position 16, does not affect traction sheave normal rotation.When emergency braking, cut off the electricity supply, electromagnet 12 loses the attractive force to head 4, the spring 8 elongating shrinks, and drives described body 2 to move to position-limiting drum 6 closing ends on guide rail, simultaneously, detent 42 is inserted described working position, and then insert abutment sleeve 14, and the rotation of traction sheave spoke 5 is braked portion 42 and stops, and traction sheave entirety is braked.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to claim scope.
