Description
Technical field
The present invention relates to machinery equipment field, and in particular to hold-down mechanism and lifting gear.
Background technology
Lifting gear is a kind of to realize that people or object complete the device that lower is moved back and forth with eminence, the weight of lifting gear
Wanting index is:1st, safety;2nd, dismantled and assembled property;3rd, have crisis releasing and escaping function.
Elevating mechanism common at present has civilian elevator, lift for building.Civilian elevator to auxiliary facility require compared with
Height can not generally use in operation outdoors;It is realized and is promoted using cable, falling accident easily occurs for cable breaks, in addition, in operation
Power failure is unfavorable for escaping.Lift for building is suitble to open air use, but needs to set up steel pipe support, and construction is relative complex,
Cost is also higher;At the same time, building lift is realized using cable and is promoted, and falling accident, safety easily occur for cable breaks
It is not high.In addition, as powered off, during in high-altitude, it is unfavorable for suing and labouring, does not have crisis releasing and escaping function.
Since outdoor study scene is not quite similar, such as field of electricity construction, job execution in pinnacled pylon is needed,
Lifting climbing equipment will be used, due to the limitation of construction site, there are larger inconvenience using existing building lift.Separately
Outer such as scene of fire, normal channel are blocked, and rescue work is assisted without effective lifting gear.
For this purpose, someone devises a kind of Simple lifter lifted by cable traction, generally comprise motor, turn
Disk, compressing member and rope, specifically for rope around turntable, compressing member compresses rope, and the rotation of motor driving disc passes through rope
Stiction between turntable, makes turntable be rolled along rope, so as to which whole device be driven to lift, the forward/reverse of motor,
Control device rises or falls.
But the existing lifting gear of the structure, wherein compressing member are generally pressing plate, are directly acted on along the radial direction of turntable
It, can be by increasing the contact area of rope and turntable in order to have enough stiction between rope and turntable on rope
It realizes, compressing member can also increase frictional force then using arc pressuring plate by increasing the pressure of compressing member at this time.It is no matter logical
Which kind of above-mentioned mode is crossed to ensure the stiction between rope and turntable, is had the following problems always:1st, in lifting gear liter
During drop, there are force of sliding friction between compressing member and rope, and the force of sliding friction and stiction pass in direct ratio
On the one hand system, the presence of the force of sliding friction can generate a large amount of heat, there are security risks, on the other hand rub for a long time,
Rope and compressing member can be made constantly to wear, equally exist security risk.2nd, compressing member is usually fixed, with usage time
Increase, compressing member is constantly worn, and pressure reduces, on the one hand stiction drops the heavy burden ability of lifting gear also with reduction
Low, on the other hand there is also the risks that stiction is mutated into force of sliding friction.
Therefore, how existing lifting gear is improved, overcome thes problems, such as it above-mentioned, be art technology
Personnel's problem urgently to be resolved hurrily.

Compared with prior art, the radial compaction mechanism of this programme has the following advantages:
1st, the use of compressing member chain structure, and idler wheel is rotary, by the cunning between original compressing member and rope
Dynamic friction is transformed to rolling friction, in order to reach maximum static friction force (i.e. maximum to bear a heavy burden) identical between rope and turntable,
Force of rolling friction is far smaller than force of sliding friction, and so as to fulfill rope and compressing member abrasion smaller, the heat of generation is also less.
2nd, compressing member along turntable in circumferential direction about in turntable periphery, since the compressing member of chain structure can be freely curved
Song allows multiple idler wheels to suppress rope contact turntable simultaneously, on the one hand can generate the pressure of bigger, so as to increase rope and turn
On the other hand maximum static friction force between disk makes the frictional force between rope and compressing member be distributed to multiple points, reduce single
The load of idler wheel, and there is gap between idler wheel, it can preferably radiate, use is more safe and reliable.
3rd, due to compressing member be chain structure, can be freely bent, thus can by regulating part adjust idler wheel and
The distance between turntable adjusts the pressure of compressing member, adjusted so as to carry out maximum bear a heavy burden;In the long-term use, it compresses
Mechanism and rope have abrasion, can also be adjusted by regulating part, it is made to keep the loading weight of safety.
4th, under external disk and idler wheel outer surface concave arc shape setting, be avoided that rope sideslip is even detached from, that improves mechanism can
By property;The inner disc corrugated setting in periphery makes its periphery have a Wave crest and wave trough, and multiple wave crests contact ropes, trough and rope it
Between have gap, make mechanism heat dissipation it is better;The setting of concave arc shape under idler wheel outer surface, moreover it is possible to increase the base of rope and idler wheel
Plinth area, in the case where pressure is identical, pressure smaller that rope receives reduces the deformation of rope, also improves mechanism
Reliability.
Compared with prior art, the lifting gear with radial compaction mechanism of this programme is having institute of radial compaction mechanism
While having advantage, have further the advantage that:
1st, the setting of arrestment mechanism can carry out fast braking under the fortuitous events such as actuating unit damage, ensure lifting dress
Putting to fall at a high speed, improve the safety of device.
2nd, leading the setting of lock station can make rope remain center, play the role of balance and stability;The setting side of handle
Convenient to operate personnel capture, while handle can also have the function of control actuating unit.
