The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Embodiment 1: as Figure 1-3, a kind of elevator traction sheave brake equipment of the present utility model, described traction sheave comprise tubular wheel body 1 and with the hollow tube-shape axle sleeve 3 of described wheel body 1 coaxial setting, link to each other by the some spokes 5 that circumferentially distribute perpendicular to described wheel body 1 between described wheel body 1 and the axle sleeve 3.Described brake equipment comprises the through hole 2 that circumferentially evenly distributes on the described wheel body 1 and put, and be positioned at the radially position-limited lever 4 of a side of described wheel body 1, described position-limited lever 4 radially arranges along described wheel body 1, and an end links to each other with cylinder 6, and described cylinder 6 can drive position-limited lever 4 with respect to described through hole 2 advance and retreat.Described through hole 2 bearing of trends are located wheel body 1 radially along the place, and described position-limited lever 4 vertically optional position has identical cross section, and the cross section is less than described each through hole 2 cross section.Described through hole 2 quantity are greater than 16, be preferably 32, the top of each through hole 2 is provided with the flexure strip 8 that a side links to each other with described wheel body 1 lateral surface one, and the side that links to each other with described wheel body 1 lateral surface one of each flexure strip 8 for each flexure strip 8 along the circumferential the same side of wheel body 1.The outside face of described each flexure strip 8 and described wheel body 1 lateral surface flush.Described position-limited lever 4 length are greater than wheel body 1 thickness.
During installation, the minor increment of described position-limited lever 4 head distance wheel bodys 1 lateral surface is less than 1/2 of position-limited lever 4 length, and when initial, position-limited lever 4 heads separate the traction sheave normal rotation with described wheel body 1 lateral surface.When needing braking, it is close to wheel body 1 lateral surface that described cylinder 6 drives position-limited lever 4, in the first situation, just in time aim at a described flexure strip 8 in the time of position-limited lever 4 touching wheel bodys 1 lateral surface, position-limited lever 4 continues close, with flexure strip 8 to the 2 interior compressions of place through hole, until be inserted in this through hole 2, even pass this through hole 2, this moment, cylinder 6 stopped to drive, because position-limited lever 4 circumferentially is fixed static with respect to traction sheave, therefore traction sheave is subject to stopping of position-limited lever 4, is braked, and stretches into these through hole 2 interior flexure strip 8 one sides also play screens to position-limited lever 4 effect, so that position-limited lever 4 is more stable in through hole 2, it is more steady that traction sheave also stops.The second situation, do not aim at a described flexure strip 8 during position-limited lever 4 touching wheel bodys 1 lateral surface fully, this moment, traction sheave was rotated further, and the propulsive effort that 6 pairs of position-limited levers 4 of described cylinder apply does not stop yet, because it is comparatively intensive that wheel body 1 circumferential through hole 2 arranges, and the outside face of each flexure strip 8 and described wheel body 1 lateral surface flush, when traction sheave rotates, position-limited lever 4 heads also can be in the unobstructive slip of wheel body 1 lateral surface, when traction sheave turns over a less angle, position-limited lever 4 can be aimed at a flexure strip 8, carries out spacing such as the first situation smoothly, braking.When recovering the traction sheave rotation, cylinder 6 drives position-limited levers 4 and withdraws from through hole 2, and corresponding flexure strip 8 returns to original position, and namely flexure strip 8 surfaces are equal with wheel body 1 lateral surface, and during convenient next braking, position-limited lever 4 is in the smooth slip of wheel body 1 lateral surface.
Embodiment 2: be with the difference of embodiment 1: what circumferentially evenly distribute and arrange on the described wheel body 1 is fluted, to replace all through holes 2 among the embodiment 1, described each groove bearing of trend is located wheel body 1 radially along the place, and the head cross section of described at least position-limited lever 4 is less than described each groove cross section.Described groove quantity is preferably 32 greater than 16, and the top of each groove is provided with the flexure strip that a side links to each other with described wheel body 1 lateral surface one.
Embodiment 3: be with the difference of embodiment 1: circumferentially not only be provided with groove on the described wheel body 1, but also be provided with through hole, described whole groove and through hole circumferentially evenly distribute along wheel body 1, described each through hole 2 bearing of trend along place, place wheel body 1 radially, described each groove bearing of trend also along place, place wheel body 1 radially, the head cross section of described at least position-limited lever 4 is both less than described each through hole cross section, again less than described each groove cross section.The quantity of described through hole and groove and greater than 16 is preferably 32, and the top of each through hole is respectively equipped with the flexure strip that a side links to each other with described wheel body 1 lateral surface one with the top of each groove.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification sheets, must determine technical scope according to the claim scope.
