Description

Belt conveyor tensioning device
Technical field
The present invention relates to a kind of belt conveyer, specifically a kind of belt conveyor tensioning device.
Background technology
Belt conveyer must be under certain tensile force effect could normal operation, it is to solve one of gordian technique that belt conveying captain distance transports that tensioning and control system provide the ability of constant tension force and repercussion fast according to adhesive tape operating condition always.2667 meters of Cheng Zhuan ore deposit main slant travelling apron total lengths, adopt fire-retardant steel cord belt, adopt electric tensioner device to guarantee that adhesive tape is in the equilibrium of various operating condition lower stress.In the high-power run at high level process of belt conveyer, expose gradually the problems such as tightening device reliability is low, tensile force is less than normal, once repeatedly occur tightly winch misoperation tripping operation or cause the accidents such as motor damage, off-axis.Be stranded this, tightening device is also had higher requirement, Given this design a kind of high efficiency conveyer tightening device, require this tightening device except possessing the advantages such as high-bearing capacity, strong stretching resistance, safe and reliable, failure rate is low, guarantee that main slant sealing-tape machine can meet the need of production of various operation conditions.
Summary of the invention
The present invention, in order to solve the problems such as in the high-power run at high level process of belt conveyer, tightening device reliability is low, tensile force is less than normal, provides a kind of belt conveyor tensioning device.
The present invention takes following technical scheme: a kind of belt conveyor tensioning device, comprise motor, retarder, cylinder, tension pick-up, steel rope, tightening device bracing frame and upside are provided with the belt roller bracing frame of belt conveyer, tightening device bracing frame downside is provided with assembly pulley I, tightening belt roller cage downside is provided with assembly pulley II, wherein motor, retarder, cylinder and tension pick-up are fixed on device support stand, being connected with retarder of motor, retarder is connected with cylinder, on cylinder, be wound with steel rope, steel rope intersection is arranged on pulley I and pulley II, the steel rope other end is fixed in tightening belt roller cage, and on steel rope, be provided with tension pick-up.
Described, motor is provided with former and later two output shafts, former and later two output shaft coaxial rotation, and an output shaft is connected with retarder, and another output shaft is connected with the external contractring brake being fixed on tightening device bracing frame.
In the present invention, drive cylinder to rotate by motor and retarder, thereby strain or loosen steel rope, under the pulling of steel rope, belt roller cage can be carried out the movement of horizontal direction, thereby the belt of belt conveyer is carried out to tensioning.
The taut band mode of former tightening device is the automatic taut band that stops, when sealing-tape machine during because of unexpected incidents sudden stop the stressed meeting of tensioning increase suddenly, easily because overtension causes tripping operation, burns motor, breaking axis.Therefore, the taut band mode taut band (only automatically regulating in operational process) that is set to stop not in the control program of tension device of rubber belt conveyor of the present invention, the system band of avoiding carries winch under emergency stop and bore hightension, winch overload damage even damages and the serious consequence that causes main shaft sealing-tape machine normally to move, both can improve safety factor, also increase the stability of equipment.
Tensioning function of the present invention completes the moving dolly that moves about of drawstring by electric-control system, pulley block balance, and tension range can be arbitrarily adjustable within the scope of 0-20T.
The present invention adopts the associated components such as high-efficiency transmission device, external drg, supporting assembly pulley, rope sheave, there is the advantages such as driving efficiency is high, bearing capacity is large, stretching resistance is strong, simple in structure, reliability is high, maintenance is little, cost is low, can meet coal mine explosion-proof safety in production demand.
The present invention adopts automatically controlled tension force to realize automatically and controls, and has realized static self-locking and the double auto-lock function of the dynamic self-locking of external drg, both can guarantee the tensioning state in adhesive tape operational process, also can ensure the safety and stability under sudden stop.
The parking taut band mode of the present invention not taut band that is set to stop, avoids adhesive tape to damage winch because of overtension, both can avoid accident to occur, stability and the service life of also having improved winch.
Compared with prior art, the present invention has the following advantages:
1) bearing capacity is large, can reach more than 10 tons, is conventionally no more than 5.5 tons abroad, maximum 8 tons.
2) simple in structure, there is no complicated hydraulic efficiency gear and other annex, thereby reliability is higher.
3) easily realize coal mine explosion-proof requirement.
4) daily attention amount is minimum.
5) cost is low, is 1/3 of import equipment.
