Description
Technical field
The present invention relates to elevators field, in particular to anti-offset traction device.
Background technique
Vehicles of common of the elevator as current people, utilization rate are very frequent.It is slided currently, elevator usually passes through traction
The traction of wheel goes up and down to realize, since hauling block rolls for a long time, so that abrasion is inevitably had between hauling block and conveyer belt,
Or due to the friction between hauling block and conveyer belt, device surface temperature is caused to increase and expand, to cause certain
Offset.If offset cannot improve, the separation that will cause between conveyer belt and hauling block is used for a long time, causes safety hidden
Suffer from, thus needs a anti-offset traction device to prevent conveyer belt from shifting from hauling block the possibility of separation.
Summary of the invention
Technical problem to be solved by the invention is to provide be not susceptible to deviate, can reduce the anti-offset of noise and safety
Traction device.
It is as follows that the present invention solves technical solution used by above-mentioned technical problem:
Anti-offset traction device of the present invention, including hauling block, conveyer belt, the hauling block surface have week
To the protrusion of distribution, the protrusion is quadrangular frustum pyramid shaped, and the side of the protrusion includes first side and second side, described first
Side is made of the opposite side of the two of them of protrusion, and the second side is made of the opposite side of raised another two, phase
The first side of adjacent protrusion is oppositely arranged, and the adjacent first side has angle, and two sides of the hauling block are all provided with
Have a circumferentially distributed flange, the flange has an inclined-plane close to the side of second side, the second side and adjacent ribs it
Between be equipped with arc groove, the one side shape that the conveyer belt is contacted with hauling block is corresponding with hauling block surface.Pass through setting
Protrusion, front-rear direction when moving conveyer belt with hauling block are resisted, and by the way that arc groove is arranged, make conveyer belt with leading
Left and right directions when drawing pulley motion is resisted, to prevent conveyer belt from occurring in the four direction all around of hauling block
Offset；Since adjacent first side has concave surface with angle, arc groove, can will not only rub because of hauling block and conveyer belt
The heat transfer generated is wiped into angle and concave surface, prevents the offset of device expansion and generation, it can also be by noise transmission to folder
In angle and concave surface, to reach noise reduction effect.
Further, the top surface of the protrusion is rectangle, can increase the resistance between conveyer belt and hauling block, from
And prevent conveyer belt from shifting on hauling block.
Further, the angle of the adjacent first side is 60 °, keeps the protrusion of hauling block more firm, to prevent
Conveyer belt on hauling block shifts during exercise, while can also improve noise transmission that conveyer belt operation generates to angle
In efficiency, reach noise reduction effect.
Further, the flange has fillet far from the side of second side, effectively can buffer and supplement because of traction
Heat that pulley and conveyer belt friction generate and the dilatancy that occurs, to prevent the conveyer belt on hauling block from sending out during exercise
Raw offset.
Further, the inclined-plane inclination angle is 45 °, effectively can be buffered and supplement because of hauling block and conveyer belt friction
The heat of generation and the dilatancy occurred, to prevent the conveyer belt on hauling block from shifting during exercise.
Further, the arc groove includes first end face and second end face, the first end face and second side position
In same plane, the second end face is perpendicular to the ground, can reduce the friction between hauling block and conveyer belt, reduces because rubbing
It wipes the heat generated and causes to expand, prevent hauling block and conveyer belt from shifting during exercise to reach.
Further, the vertical range of the arc groove vertex to raised bottom surface is less than the radius of arc groove, can
The friction between hauling block and conveyer belt is reduced, reduce causes to expand because of the heat that friction generates, and prevents from drawing to reach
Pulley and conveyer belt shift during exercise.
Further, the transmission belt surface both ends extend to form arm to the hauling block, on the inside of the arm with
The flange outer sides are in close contact, fixation of the auxiliary conveyor belt on hauling block, to prevent hauling block and conveyer belt from transporting
It shifts when dynamic.
The present invention compared with the existing technology has the following advantages that and effect: by setting protrusion, sliding conveyer belt with traction
Front-rear direction when wheel movement is resisted, the right and left by the way that arc groove is arranged, when moving conveyer belt with hauling block
To resisting, to prevent conveyer belt from shifting in the four direction all around of hauling block；Due to adjacent first side
Face has concave surface with angle, arc groove, can not only arrive the heat transfer generated by hauling block with conveyer belt friction
In angle and concave surface, the offset of device expansion and generation is prevented, it can also be by noise transmission into angle and concave surface, to reach
Noise reduction effect；Increase the resistance between conveyer belt and hauling block, keeps the protrusion of hauling block more firm, reduce hauling block
Friction between conveyer belt occurs due to effectively capable of buffering and supplement the heat because of hauling block and conveyer belt friction generation
Dilatancy；Efficiency of the noise transmission of conveyer belt operation generation into angle is improved, noise reduction effect is reached；Auxiliary conveyor belt exists
Fixation on hauling block, to prevent conveyer belt from shifting on hauling block.
