Description
Technical field
The utility model relates to a kind of technical field of piler, more specifically relate to a kind of stacker loading platforms overspeed protection device.
Background technology
Overspeed protection device is also one of safety guard of piler.When the loading platform lifting of piler, because of certain reason (hypervelocity or disconnected rope) make loading platform exceed the speed limit tenesmus time, the motion of velocity limiter hypervelocity is driven by hypervelocity steel rope, thus the rope sheave hypervelocity on velocity limiter is rotated, when reaching the speed preset, the ratchet of velocity limiter will block ratchet automatically, now governor sheave stops operating, automatically make travel switch cut off the electricity supply simultaneously, because driving wire rope is by balance block effect, this just forces the eccentric wheel of the device of braking and gripping to rotate, thus the device of braking and gripping firm grip is being hoisted on guide rail.The shortcoming of this structure is that eccentric clamping surface is too narrow, and easily skidding when clamping can't clip, and stopping distance is oversize, and reaction is not very sensitive.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide one to increase clamping surface, cancels column guide rail, and is clamped in leg surface more failure-free overspeed protection device.
The utility model is realized by following technical scheme.
A kind of overspeed protection device of stacker loading platforms, comprise column, loading platform, overload rope-loosing protection device, safety lever, clamping slipper, described column both side surface serves as guide pass, loading platform is arranged on inside two columns, front and back two side guide wheel of loading platform contacts with front and back leg surface with interior side guide wheel, the hoisting mechanism steel rope that hoists is connected respectively at loading platform by pulley before and after entablatrance, overload rope-loosing protection device is provided with between described loading platform and steel rope, the first end of described safety lever and overload fender guard of restricting is connected, second end of described safety lever with loading platform clamps slipper and is connected, described clamping slipper is arranged on loading platform both sides, described clamping slipper is in the face of two column sides, apart from stud sides surface 2mm.
As this technical scheme further, be articulated and connected between described clamping slipper first end and safety lever.Described safety lever prizes principle by connecting rod, promotes, bottom clamping slipper, up to do oblique movement, thus make toothed slipper be pressed on leg surface.
As this technical scheme further, described overload rope-loosing protection device comprises cylindrically coiled spring and pressure sensor.
As this technical scheme further, described loading platform clamping braking is symmetrical structure.
Beneficial effect: the utility model clamping slipper instead of original eccentric wheel clamping mode, eliminate column guide rail, and on the two sides of loading platform, such structure is all housed, and traditional loading platform only has a clamping structure, such design can increase clamping surface, two sides can clamp simultaneously, and clamping is more reliable, and its great advantage saves column guide rail; In addition, instead of original disk spring with cylindrically coiled spring, make the reaction of overspeed protection device sensitiveer, shortening loading platform greatly because of unexpected situation exceeds the speed limit the distance run on column.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the present embodiment.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the left view of Fig. 1.
detailed description of the invention:
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
See Fig. 1, Fig. 3, a kind of overspeed protection device of stacker loading platforms, comprise column 1, loading platform 2, overload rope-loosing protection device 3, safety lever 4 and clamping slipper 5.Piler is provided with two root posts 1, the top of column 1 is provided with entablatrance.Column 1 both side surface serves as guide pass, and on the guide pass being arranged on inside two columns of loading platform 2, the hoisting mechanism that hoists is connected respectively at loading platform by pulley before and after entablatrance.The hoisting mechanism that hoists comprises lifting motor, lifting pulley 7, hoist rope 8.Loading platform 2 is symmetrical structure.The lifting pulley 7 that hoist rope 8 is walked around on entablatrance is connected with loading platform 2 left and right sides.Arrange between loading platform 2 and hoist rope 8 and transship fender guard 3 of restricting.
See Fig. 2, overload rope fender guard 3 comprises cylindrically coiled spring 31 and pressure sensor 32.Cylindrically coiled spring 31 first end is connected with steel rope, and the second end is connected with pressure sensor 32.Pressure sensor 32 is fixed on the first end of safety lever 4 by pole, and safety lever 4 is L like shape, and the second end of safety lever 4 is fixed on loading platform 2.The flex point place of safety lever 4 and clamping slipper 5 are connected by hinged mode and prop up bottom clamp, and the other end of clamping slipper 5 is fixed on loading platform 2 by adapter plate 6.The adjacent column two sides of the side flank of tooth of clamping slipper 5, clamping slipper 5 is 2mm with column side initial separation.During work, when steel rope for a certain reason (hypervelocity or disconnected rope) fracture time, cylindrically coiled spring 31 first deformation occurs thus pressure sensor 32 receives signal, and by this signal transmission to system, system shutdown power supply shuts down proterctive equipment.Meanwhile, due to wire cable rupture, the pressure on safety lever 4 there occurs change, safety lever 4 is equipped with overload slack rope end and is upturned, thus promotion clamping slipper 5 does upwards oblique movement, is clamped in column both side surface tightly.The utility model clamping slipper instead of original eccentric wheel clamping mode, and on the two sides of loading platform, such structure is all housed, and traditional loading platform only has a clamping structure, design can increase clamping surface like this, two sides can clamp simultaneously, clamps more reliable; Serve as guide pass inside this structure column, eliminate guide rail, simplify apparatus structure; In addition, instead of original disk spring with cylindrically coiled spring, make the reaction of overspeed protection device sensitiveer, shortening loading platform greatly because of unexpected situation exceeds the speed limit the distance run on column.
