Description
Technical field
The utility model relates to a kind of Hydranlic tensioner, and the Hydranlic tensioner that specifically a kind of hydraulic cylinder travel is controlled, is applied to belt conveyer.
Background technology
Belt conveyer is a kind of load transfer device being widely used in bulk material in commercial process.In normal use procedure, the phenomenon causing greatly bumpy motion spent by the transport belt slippery adopting hydraulic cylinder tensioning device to prevent the reason such as aging, solid accumulation is uneven, mechanical device wearing and tearing due to load-transfer device from occurring or load-transfer device pendency.But the hydraulic actuating cylinder at present in Hydranlic tensioner does not have stroke detection, namely when in the overall all retraction hydraulic cylinders of piston rod, Hydranlic tensioner cannot meet the requirement of cushion stroke, do not have due absorption buffer action, just there will be load-transfer device this time cannot tensioning, occurs skidding.
Summary of the invention
For above-mentioned prior art Problems existing, the purpose of this utility model is to provide the controlled Hydranlic tensioner of a kind of hydraulic cylinder travel, the effective travel of hydraulic actuating cylinder can be detected, ensure that Hydranlic tensioner meets the requirement of cushion stroke, make belt conveyer smooth running.
For achieving the above object, the technical solution adopted in the utility model is: the Hydranlic tensioner that a kind of hydraulic cylinder travel is controlled, comprise tensioning dolly, steel rope, static line seat, electric cabinet, movable pulley, Hydraulic Station, Accumulator arrangements, hydraulic actuating cylinder, hydraulic actuating cylinder bearing, load-transfer device and displacement pickup, described load-transfer device is placed on tensioning dolly, and movable pulley is fixed on the piston rod of hydraulic actuating cylinder; Steel rope one end is connected and fixed rope seat, and the other end is connected on tensioning dolly through movable pulley; Hydraulic actuating cylinder is fixed on hydraulic actuating cylinder bearing, and Accumulator arrangements one end is connected with hydraulic actuating cylinder, and the other end is connected with Hydraulic Station, and institute's displacement sensors is arranged on the afterbody of described hydraulic actuating cylinder, and displacement pickup is connected with electric cabinet.
Before belt conveyer starts startup, displacement pickup just must detect that whether the effective travel of hydraulic actuating cylinder meets the requirement of cushion stroke, when meeting the demands, is sent to electric cabinet by detection signal, and conveyer starts then.When conveyer starts, load-transfer device can laxly suddenly extend, hydraulic actuating cylinder now responds rapidly, piston rod is retracted oil cylinder immediately, the stressed movement of tensioning dolly, be placed in the stressed tensioning of load-transfer device on tensioning dolly simultaneously, compensate for the elastic oscillation produced due to elongation in time, effectively realize the dynamic tension of belt conveyer, reduce impact minor load, thus steadily reliable when belt conveyer is started.
The utility model have employed the hydraulic actuating cylinder with displacement pickup, can detect whether the effective travel of hydraulic actuating cylinder meets the requirement of cushion stroke in time, ensure that when load-transfer device lax elongation suddenly, hydraulic actuating cylinder can respond rapidly, piston rod is retracted oil cylinder in time, realize the dynamic tension of belt conveyer, actv. ensure that the safe and reliable operation of belt conveyer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the Hydranlic tensioner that a kind of hydraulic cylinder travel is controlled, comprise tensioning dolly 1, steel rope 2, static line seat 3, electric cabinet 4, movable pulley 5, Hydraulic Station 6, Accumulator arrangements 7, hydraulic actuating cylinder 9, hydraulic actuating cylinder bearing 8, load-transfer device 11 and displacement pickup 10, described load-transfer device 11 is placed on tensioning dolly 1, and movable pulley 5 is fixed on the piston rod of hydraulic actuating cylinder 9; Steel rope 2 one end is connected and fixed rope seat 3, and the other end is connected on tensioning dolly 1 through movable pulley 5; Hydraulic actuating cylinder 9 is fixed on hydraulic actuating cylinder bearing 8, and Accumulator arrangements 7 one end is connected with hydraulic actuating cylinder 9, and the other end is connected with Hydraulic Station 6, and institute's displacement sensors 10 is arranged on the afterbody of described hydraulic actuating cylinder 9, and displacement pickup 10 is connected with electric cabinet 4.
Before belt conveyer starts startup, displacement pickup 10 just must detect that whether the effective travel of hydraulic actuating cylinder 9 meets the requirement of cushion stroke, when meeting the demands, is sent to electric cabinet 4 by detection signal, and conveyer starts.When conveyer starts, load-transfer device can relax elongation, hydraulic actuating cylinder 9 now responds rapidly, piston rod retraction oil cylinder, the stressed movement of tensioning dolly 1, be placed in the stressed tensioning of load-transfer device on tensioning dolly 1 simultaneously, compensate for the elastic oscillation produced due to elongation in time, effectively realize the dynamic tension of belt conveyer, reduce impact minor load, steadily reliable when belt conveyer is started.
Preferably, the conveniently connection of each parts, described Accumulator arrangements 7 one end adopts high pressure hose to be connected with hydraulic actuating cylinder 9, and the other end is connected with Hydraulic Station 6 by high pressure hose.
Preferably, the fixing rope clamp in described steel rope 2 one end is connected and fixed rope seat 3, and the other end is fixed on tensioning dolly 1 through adopting static line folder after movable pulley 5.
