The further improvement of the utility model is: the rope stretching of two emery wheels of the corresponding emery wheel in the two ends of said base mechanism and the position of going into to restrict are respectively arranged with guide wheel; Wherein the guide wheel of rope-out end comprises one guide wheel and two is laterally longitudinally; They are combined into guide wheel group, and two horizontal guide wheels are arranged side by side up and down.
The further improvement of the utility model is: between said hydraulic pump and the fuel tank oil return line be provided with the band pressure-regulating valve overflow valve and with the parallelly connected short circuit oil pipe of overflow valve, on the short circuit oil pipe valve is set.
The further improvement of the utility model is: said pay off rack mainly comprises plate wheel and the support of depositing the guiding rope; The plate wheel cross-under is compressing the location on one transverse axis and by the stifled fixed block that reaches of the wedge on the transverse axis that is positioned at the plate wheel two ends; End at transverse axis is provided with the frictional disk that is fixedly connected with transverse axis; The frictional disk inboard be provided with one stretch into the plate wheel end pusher dog, be provided with on the transverse axis in the frictional disk outside and relatively rotate the sliding sleeve that cooperates with transverse axis, sliding sleeve is erected at an end of support; The braking mechanism that fixed connection one cooperates with frictional disk on the sliding sleeve; Said braking mechanism comprises the brake pad that cooperates with frictional disk, and brake pad holds out against through the stage clip that is arranged in the sleeve, and the outer end of sleeve is provided with the slide block and the jackscrew of top pressure spring.
Owing to adopted technique scheme, the technological progress that the utility model is obtained is:
The structure of the miniature tensioner of the utility model has reached to be simplified most, and the connected mode of each parts also reaches to be simplified most, so it is in light weight, easy to carry, and being adapted to set up the power transmission line initial stage is that the guiding rope provides tension force to use.The guide wheel setting of the utility model can make the guiding rope when going into out tensioner, can both play guide effect, is unlikely to make the guiding rope to scurry situation such as groove winding.Being provided with of overflow valve can make the tension force of emery wheel change within the specific limits, and short circuit oil pipe and valve thereof be provided with can this tensioner tension force reach minimum, the frictional force of surplus tensioner only almost.
