Abstract
The utility model relates to a tensioning device, in particular to a hydraulic tensioning device. The hydraulic tensioning device comprises a hydraulic tensioning cart, movable pulley sets, a main hydraulic cylinder, a hydraulic pump station and a low-speed winch, wherein the hydraulic pump station is connected with the main hydraulic cylinder, the hydraulic tensioning cart is connected with the main hydraulic cylinder through the movable pulley sets, and the movable pulley sets are connected through steel wire ropes. One end of each steel wire rope is fixed to a wall, and the other end of each steel wire rope is connected to the low-speed winch. The hydraulic tensioning device is stable, reliable and convenient to adjust and control and can effectively control the plastic deformation of a conveyor belt and the slipping phenomenon caused by insufficient tensile force under all kinds of poor conditions; meanwhile, traction and brake of the tensioning cart and a roller under the large-stroke condition are achieved when broken belt adjustment and one more time of connection are carried out on a belt conveyor.
Description
Technical field
The utility model relates to tightening device, particularly a kind of Hydranlic tensioner.
Background technology
The tightening device of belt conveyer is as an important component part in belt conveyer, and its effect is irreplaceable.Existing machinery tensioning, as fixed type, weight hammer type, but tightening device not only can not produce constant tensile force, even can produce the situation that tensile force lost efficacy, and causes its get out of hand, and safety factor is low; And tensile force can not regulate, and make belt conveyer unloading phase or operational throughput send when changing and load-transfer device occur because of the not enough phenomenons such as transport belt slippery that cause of tension force, the working space of heavy-hammer-tightening is larger in addition.
At present, dynamic type take-up device also has research, through development for a long time, be widely used on various load-transfer devices, but, fail effectively to solve the phenomenon that load-transfer device plastic elongation and tension force skid not, and can not realize traction and the braking of tensioning dolly and the larger stroke of cylinder.
Utility model content
For the defect existing in prior art, the purpose of this utility model is a kind of Hydranlic tensioner.
For reaching above object, the technical scheme that the utility model is taked is:
A Hydranlic tensioner, comprises hydraulic tensioning dolly, running block, main hydraulic cylinder, hydraulic power unit, low speed winch, and described hydraulic power unit connects main hydraulic cylinder; Described hydraulic tensioning dolly is connected with main hydraulic cylinder by movable pulley, movable pulley and movable pulley; Between described running block, by steel rope, connect; Described steel rope one end is body of wall fixedly, and the other end connects described low speed winch.
Hydraulic power unit, as the power resources of Hydranlic tensioner mainly by the power needs that provide pressure oil to realize system for system.
On the basis of above scheme, also comprise flame proof control box, described flame proof control box is connected with hydraulic power unit.Flame proof control box, fender guard, when belt conveyer is worked, plays isolation, explosion-proof.
On the basis of above scheme, also comprise accumulation of energy station, described accumulation of energy station is connected with hydraulic power unit.Accumulation of energy station, is the pressure oscillations of absorption system, savings energy, the effect that supplements flow, pressurize and maintenance pressure when pump capacity is not enough.
On the basis of above scheme, described running block also comprises movable pulley, and one end that described steel rope is fixed on body of wall connects auxiliary hydraulic cylinder by movable pulley.
The beneficial effects of the utility model: steadily reliable, easy to adjust, be convenient to control, under various mal-conditions, the phenomenon that actv. control load-transfer device plastic deformation and tension force skid not, simultaneously, when belt conveyer is carrying out broken belt adjustment and again during joint, realizing traction and the braking of tensioning dolly and the larger stroke of cylinder.
