Description
Technical field
The utility model relates to numerical control winch and cylinder type Hydranlic tensioner, is particularly useful for adjustment and the control of ground such as harbour, harbour, power plant, washery with the tensile force that the stroke of tension amount is big in the belt conveyer operational process.
Background technology
Belt conveyer is one of actv. load transfer device at present, has that traffic capacity is big, simple in structure, investment cost is relatively low and characteristics such as easy to maintenance.Tightening device is the important component part in the belt conveyer, and the quality of its performance directly influences the performance of belt conveyer.The main effect of tightening device guarantees to carry to have enough tension force exactly, prevents skidding.
Domestic common belt conveyer tightening device has weight tensioning and jinny tensioning at present, has occurred hydraulic oil cylinder type and hydraulic wireline winch formula tightening device in recent years again.The gravity takeup structure is the simplest, and is most widely used general, and its advantage is that the tensioning displacement is variable, and shortcoming is that tensile force is constant, is unfavorable for regulation and control starting and operating tensile force; The fixed type tightening device is meant that belt tensioning drum can sway change tensile force at the conveyer prestart with after shutting down; but just can adjust after must and shutting down at prestart; and the position is constant all the time in operational process; tensile force changes with the variation of tension force, also is to be unfavorable for regulation and control starting and operating tensile force.Because the fixed tensioning mode can only regularly be adjusted the tensioning degree of load-transfer device, generally be initially located in tensioning state, make the load-transfer device of belt conveyer bear extra increment load, therefore tensile force increases along with the load-transfer device permanent deformation and reduces gradually in operational process, skidding often occurs.When existing hydraulic oil cylinder type tightening device can require to regulate conveyer arbitrarily according to the difference of the different operating modes of conveyer and belt tension and starts and the tensile force during smooth operation; can compensate the elongation of load-transfer device; make conveyer start steadily; can protect load-transfer device preferably; but the stroke of tension of this hydraulic oil cylinder type tightening device is subjected to the restriction of oil cylinder length to a great extent; but also digital control required tensile force, the realization automatic guidance set arbitrarily of impassabitity.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model provide a kind of can satisfy the tensile force stroke long, in good time, appropriate regulation, fast numerical control winch and the cylinder type Hydranlic tensioner of speed of response.

The beneficial effect of the utility model numerical control winch and cylinder type Hydranlic tensioner is:
1. adopt hydraulic wireline winch and tension adjustment oil cylinder fit system as the tensioning actuating unit: to realize the adjustment and the pretension of belt conveying captain distance realizing short-range stroke adjustment and reflection fast by the tension adjustment oil cylinder by hydraulic wireline winch.Thereby realize automatically the tension force of belt conveyer when starting big (1.1-1.5 of tension force doubly when being about normal operation), the little tensioning action of tension force during normal operation, with satisfy prevent from when load-transfer device starts to skid and load-transfer device when normally moving to the different requirements of tensile force.
2. stroke of tension is big, comformability is strong: can design stroke of tension as the case may be, the Chu Shengliang that rationally matches winch realizes the needs of stroke of tension, satisfies the requirement of various dissimilar belt conveyers to tightening device.
3. adopt the cold reserve mode: the unloading phase of belt conveyer, Hydraulic Station starts, the pressure control of setting according to man-machine interface starts tension force, running tension, after belt conveyer operates steadily, the Hydraulic Station outage, utilize energy storage that the tension adjustment oil cylinder is carried out cold reserve, make the tension adjustment oil cylinder keep constant tensile force.Can reduce energy loss and fault rate thereof that the operation of electrical motor and hydraulic pressure component element long period brings.
4. adopt tension monitor to detect the tensile force of tension adjustment oil cylinder in real time: the signal that detects to be offered Programmable Logic Controller (PLC), make it participate in control.At the belt conveyer normal operating phase, owing to Hydraulic Elements are revealed or reason such as belt elongation when causing tensile force to reduce, the signal that detects when tension monitor is during less than certain setting value, and Hydraulic Station restarts and reaches normal tensioning pulling force.
5. tensioning speed is fast, response time short: when belt conveyer starts; the slack list of load-transfer device can laxly suddenly be extended; tensioning hydro-cylinder is under the effect of energy storage; can shrink the elongation of piston rod compensation load-transfer device at once; reduce of the impact of load-transfer device slack list to pilled-in selvedge; make the belt conveyer starting steadily, reliably, and protected load-transfer device preferably, reduce the generation of broken belt accident.Produce fluctuation when load-transfer device is extended suddenly when external disturbance or load-transfer device dynamic tension during normal operation, energy storage can in time absorb the elongation of load-transfer device slack list, and the fluctuation of minimizing load-transfer device dynamic tension makes system be in pressure constant state, prevents to skid.
6. reliability height, fault rate are low, easy to maintenance: the maintenance of tightening device can not finished under the stopped status at belt conveyer, has reduced maintenance cost, has guaranteed the work-hours of belt conveyer.
7. but hydraulic wireline winch formula tightening device automatic compensation belt tension, better to large conveying quantity, long belt conveyor applicability, the hydraulic wireline winch tightening device can automatically be realized real-time control according to the variation of conveyer tension force, can prevent effectively that load-transfer device is in the skidding that rises, causes in the braking procedure, the rising of complete machine, deceleration and stopping performance are improved, to satisfy the requirement of the normal operation of belt conveyer.
