Abstract
A hydraulic automatic tensioning device is characterized in that a buffering cylinder is installed on a cylinder base; a steel wire rope on a hydraulic winch connects the hydraulic winch, the buffering cylinder, a tension sensor, a travelling dolly and a fixed base together; a hydraulic pump station is connected with the buffering cylinder, a hydraulic winch motor and an energy accumulator through a high-pressure hose; and the sensor is connected with an electric control cabinet. With the structure, the hydraulic automatic tensioning device is capable of adjusting tensile force automatically relative to the difference tensile forces required in start and normal work of a conveyer according to the characteristics of conveying equipment, has the advantages of rapid response and high storage and transport capacity, realizes automatic tensioning and monitoring and meets the requirements of production.
Description
Technical field
The utility model relates to a kind of tightening device of transportation device, especially the tightening device of the transportation devices such as the comprehensive digging in colliery and major port, coal jetty, power plant.
Background technology
In recent years freight volume, haul distance and the crossheading band of transportation device not being shut down mobile tail etc. has had higher requirement, and present existing tightening device exists effective protection system is not set; The tensioning speed of response is slower; The accumulating ability is little; Basically all auto-tensioning and monitoring can not be realized, the requirement of production can not be satisfied.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic auto tensioner, and this device can be according to the characteristics of load transfer device, to conveyer start with normal operation in need different tension force, can pass through the automatic tension adjusting of hydraulic efficiency gear.
The purpose of this utility model is achieved in that cushion cylinder is installed on the cylinder pedestal, steel rope on the hydraulic wireline winch connects hydraulic wireline winch, cushion cylinder, pulling force sensor, travelling car, firm banking, hydraulic power unit connects with high pressure hose and cushion cylinder, hydraulic winch motor and energy storage, and sensor connects electric cabinet.
Because the utility model adopts said structure, this device can be according to the characteristics of load transfer device, to conveyer start with normal operation in need different tension force, can automatic tension adjusting, speed of response is fast, and the accumulating ability is large, realize auto-tensioning and monitoring, satisfied the requirement of producing.
Description of drawings
Fig. 1 is the constructional drawing of the utility model embodiment.
Fig. 2 is the birds-eye view of Fig. 1.
1 travelling car, 2 pulling force sensors, 3 firm bankings, 4 cushion cylinders, 5 cylinder pedestals, 6 energy storages, 7 hydraulic power units, 8 electric cabinets, 9 hydraulic wireline winchs, 10 steel ropes, 11 high-pressure rubber pipes among the figure.
The specific embodiment
Embodiment: this installs by travelling car 1, pulling force sensor 2, firm banking 3, cushion cylinder 4, cylinder pedestal 5, energy storage 6, hydraulic power unit 7, electric cabinet 8, hydraulic wireline winch 9 compositions such as grade, cushion cylinder 4 is installed on the cylinder pedestal 5, steel rope 10 on the hydraulic wireline winch 9 is with hydraulic wireline winch 9, cushion cylinder 4, pulling force sensor 2, travelling car 1, firm banking 3 connects, hydraulic power unit 7 usefulness high pressure hoses 11 and cushion cylinder 4, hydraulic winch motor and energy storage 6 connect, pulling force sensor 2 connects electric cabinet 8, and electric cabinet 8 is controlled the startup of Electric Machine at Pumping Station, stop.
In Fig. 2, be connected to cushion cylinder 4 by the steel rope 10 on the hydraulic wireline winch 9 with travelling car 1 and then be affixed on the firm banking 3 with pulling force sensor 2, hydraulic power unit 7 usefulness high-pressure rubber pipes 11 are connected with cushion cylinder 4 energy storages 6 and hydraulic wireline winch 9.Fire proof motor and electromagnetic valve are connected on electric cabinet 8 and the pulling force sensor hydraulic power unit 7; the hydraulic power unit electric motor starting is tightened to mode of operation to hydraulic pressure winch 9 cushion cylinders 4 and energy storage 6 supply hydraulic fluids with travelling car 1 and provides a signal by pulling force sensor 2 to electric cabinet 8 during work, and electric cabinet 8 notice hydraulic power units 7 are shut down.Carry out pressurize for cushion cylinder supply pressure oil by energy storage 6.After after a while, owing to interior let out etc. provides a signal by pulling force sensor 2 feedback electric cabinets 8 after the reason tensioning pressure drops to certain value.7 startups of electric cabinet 8 notice hydraulic power units are arrived setting value to hydraulic pressure winch 9. cushion cylinders 4 and energy storage 6 fuel feeding replenishment system pressure.Then pulling force sensor 2 provides a signal for electric cabinet 8, and notice hydraulic power unit 7 stops control lever by energy storage 6 pressurizes, get final product.
