Abstract
The utility model discloses a hydraulic automatic stretching device, which comprises a pulling force sensor, a fixed rope seat, a guide rope roller, a tensioning cylinder, a tensioning cylinder seat, a hydraulic station, a PLC control box and a tensioning trolley. The PLC control box is connected with the hydraulic station. The hydraulic station is connected with the tensioning cylinder. The tensioning cylinder is mounted on the tensioning cylinder seat. Fork pin connection is provided between the guide rope roller and the tensioning cylinder. One end of the pulling force sensor is connected with the tensioning trolley, and the other end is connected with a steel wire rope. The steel wire rope is connected with the pulley inside the fixed rope seat. With the hydraulic automatic stretching device, phenomena of plastic deformation of a conveying belt and slipping of the conveying belt caused by insufficient tension are effectively controlled under various harsh conditions; especially with the tension sensor, a pulling force of a single steel wire rope can be effectively measured, the pulling force for better tensioning the device can be back to the PLC, such that the pulling force can be controlled in a set range accurately and a conveying machine is made to run in the best state.
Description
Technical field
The utility model relates to a kind of load-transfer device take-up device, is specifically related to the hydraulic pressure automatic tensioner.
Background technology
Weight hammer type, fixed type, self acting take-up device through development for a long time, have been widely used on the various load-transfer devices, and its appearance has solved the phenomenon that load-transfer device plastic elongation and tension force skid inadequately well.
With regard to take-up device, it is mainly used in conveyer at present, makes load-transfer device keep enough tension force, but aspect details or defectiveness, so the improvements of needs are still arranged.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art; A kind of hydraulic pressure automatic tensioner is provided; Measure the pulling force on the individual wire through pulling force sensor, feed back to the start and stop that the PLC control box comes the adjusting Hydraulic Station of automation, the oil cylinder pulling force is controlled in the weight range that sets accurately; Thereby realize the automation of take-up device, saved the energy.
The technical scheme that the utility model adopts is: a kind of hydraulic pressure automatic tensioner; Comprise pulling force sensor, static line seat, sheave, drawing cylinder, drawing cylinder seat, Hydraulic Station, PLC control box and tensioning dolly; Said PLC control box is connected with Hydraulic Station, and Hydraulic Station is connected with drawing cylinder, and drawing cylinder is installed on the drawing cylinder seat; Said sheave is connected with drawing cylinder jaw bearing pin; Said pulling force sensor one end connects the tensioning dolly, and an end connects steel rope, and steel rope is connected with the interior pulley of static line seat.
When hydraulic pressure automatic tensioner tension load-transfer device; Pulling force sensor is measured the pulling force on the individual wire; Feed back to the start and stop that the PLC control box comes the adjusting Hydraulic Station of automation; The oil cylinder pulling force is controlled in the weight range that sets accurately, thereby realizes the automation of take-up device, saved the energy.
The utility model can be through regulating shutter board; Utilize pulling force sensor to measure the pulling force on the individual wire; Feed back to the start and stop that the PLC control box comes the adjusting Hydraulic Station of automation; The oil cylinder pulling force is controlled in the weight range that sets accurately, thereby realizes the automation of take-up device, saved the energy.
Beneficial effect: the utility model can be under various harsies environment; The phenomenon that actv. control load-transfer device plastic deformation and tension force skid inadequately; The pulling force of single wire rope is measured in the particularly appearance of this pulling force sensor effectively, can feed back to the PLC pulling force of take-up device better; Pulling force is controlled in the setting range accurately, makes conveyer operate in optimum regime.
