Description
Technical field
The utility model relates to mechanical equipment technical field more particularly to a kind of dedicated tensioners of Great span.
Background technique
When meeting across mountain, across river operating condition, unwrapping wire is difficult, and helicopter Setting-out Technique occurs, and solves Great span and puts
The problem of line, still, due to going straight up to the high-speed demand of machine travel guide rope unwrapping wire, need it is a kind of can be with high speed unwinding and stable
Tensioner, but current common tensioner is not able to satisfy high speed unwinding requirement, therefore can not be used for Great span unwrapping wire.
Utility model content
Purpose of the utility model is to solve the above problems, and provide a kind of dedicated tensioner of Great span.
In order to complete above-mentioned target, the utility model the following technical schemes are provided:
A kind of dedicated tensioner of Great span, including rack, rack is equipped with wheel shaft, hydraulic system and engine, on wheel shaft
Equipped with straining pulley, the straining pulley two sides are separately connected one group of fluid pressure drive device, and the fluid pressure drive device includes hydraulic control
Device, high-speed hydraulic motor and the speed reducer being connect with high-speed hydraulic motor processed, the output shaft driving straining pulley rotation of speed reducer；
The hydraulic system includes fuel tank and hydraulic pump, and the oil return line on the hydraulic pump and fuel tank is equipped with overflow valve；The hair
Motivation connects hydraulic pump, and hydraulic pump is respectively cooperating with two high-speed hydraulic motors and connect.
Preferably, the hydraulic pump is variable pump, can be convenient control flow, and then controls turning for high-speed hydraulic motor
Speed.
Preferably, outlet sealing frame before the frame front is fixedly installed with, preceding outlet sealing frame upper end is fixed with guiding
Wheel, the wirerope for solving to go straight up to when machine travel guide rope carries out setting-out work move towards deflection.
The utility model has the following beneficial effects: 1, using high-speed hydraulic motor, be adapted to go straight up to machine travel guide rope into
High-speed demand when row line laying work；2, it is worked at the same time using two sets of mutually independent fluid pressure drive devices, it is a set of to go wrong separately
It is a set of to work on, the hydraulic system when going straight up to machine travel guide rope and carrying out line laying work can be reduced and run at high speed
Cause tensioner emergency shutdown or out-of-control phenomenon occurrence probability, avoids causing more serious consequence.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the application.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the hydraulic system connection signal schematic diagram of the application.
Specific embodiment
As described in Fig. 1-Fig. 3, a kind of dedicated tensioner of Great span, including rack 1, rack 1 are equipped with wheel shaft, hydraulic system
With engine 11, wheel shaft is equipped with straining pulley 6, and 6 two sides of straining pulley are separately connected one group of fluid pressure drive device, described hydraulic
Driving device includes hydraulic control device, high-speed hydraulic motor 9 and the speed reducer 8 connecting with high-speed hydraulic motor 9, speed reducer 8
Output shaft driving straining pulley 6 rotate；The hydraulic system includes fuel tank 4 and variable pump 10, and fuel tank side is equipped with radiator 3, institute
The oil return line stated on variable pump 10 and fuel tank 4 is equipped with overflow valve；11 link variable of engine pump 10, variable pump 10 with
Two high-speed hydraulic motors 8 are respectively cooperating with connection；Control box 7 is equipped with above rack 1, two hydraulic control devices are set to operation
In case 7.
Outlet sealing frame 2 before 1 front of rack is fixedly installed with, 1 rear of rack are equipped with rear directive wheel 5, preceding outlet sealing frame 2
Upper end is fixed with directive wheel 12, and the wirerope for solving to go straight up to when machine travel guide rope carries out setting-out work moves towards deflection.
In actual work, engine 11 converts mechanical energy to the hydraulic energy of variable pump 10, the driving high speed of variable pump 10
Hydraulic motor 9, speed reducer 8 drive 6 high-speed rotation of straining pulley, adapt in Great span environment unwrapping wire, go straight up to machine travel guide rope
Carry out high speed unwinding requirement when line laying work.
Worked at the same time using two sets of mutually independent fluid pressure drive devices, it is a set of go wrong it is another set of can work on,
The hydraulic system when going straight up to machine travel guide rope and carrying out line laying work can be reduced and run at high speed and cause tensioner and promptly stop
Machine or out-of-control phenomenon occurrence probability avoid causing more serious consequence.
