Description
Technical field
The utility model relates to a kind of spreading device, is particularly useful for the uphill assisting device (climb-aiding device) using pull rope, makes pull rope keep tensile force, thus enables the power that uphill assisting device provides enough.
Background technology
Have in the installations and facilities of larger height at Feng Ta, communication tower, chimney etc., be usually all provided with for staff's cat ladder up and down.In order to the labour intensity reduced a staff, the uphill assisting device matched with cat ladder has been installed in part facility, this device is connected with the safety belt of staff by open loop or closed rope, drives rope thus provide power-assisted to staff by motor.
Motor drives the mode of rope to be driven by frictional force, and needs to provide enough power-assisteds just to need enough frictional force, and just needs tensioning apparatus to provide enough tensile forces for rope to strengthen this frictional force.Rope tension power passes through adjustment usually to meet designing requirement when equipment is installed, but its numerical value can diminish gradually and cause the driving force of whole device not enough, and its phenomenon shows as, and occurs skidding and wearing and tearing in driving process between driving wheel and rope.It is determine due to the characteristic properties of rope that rope tension power can diminish gradually, first rope there will be permanent set under the effect of tensile force, it is especially remarkable when stroke of ascending a height is larger, secondly in running, rope by bending, can cause fatigue deformation through driving wheel and deflecting roller.Above-mentioned distortion all belong to permanent deformation and along with accumulated time and access times increase and constantly become large.Therefore, effectively must detect the actual tensile force of driving wheel, and compensate the permanent deformation driving rope.
At present, for solving the problem of closed rope permanent set in uphill assisting device, usually needing when mounted with euphroe, rope to be tightened up, as much as possible rope permanent set being discharged in the process of installing.After uphill assisting device employs a period of time, rope can be out of shape gradually, and tensile force also just diminishes and can make rope slipping gradually, cannot use.At this moment, common solution, after being removed by cable nipple, is again hauled according to method described before, after then cutting off redundance, and joint again.
Several shortcoming is there is in above method in the operational applications of reality:
Larger labour intensity is needed when 1, using euphroe to do tight rope operation.
