Abstract
The utility model discloses a rubber belt conveyor tail ballast tightening device, it is equipped with track and sports car on rubber belt conveyor's tail frame, rubber belt conveyor's reversing drum installs on the sports car, make reversing drum can be on the tail frame back -and -forth movement, hang first fixed pulley at rubber belt conveyor tail rear top, tail rear fixed mounting tensioning prop pulling machine, install the second fixed pulley on the tensioning prop pulling machine, wire rope's one end tractive is on the sports car, the wire rope other end is walked around to fix behind second fixed pulley and the first fixed pulley again and is weighed down the stone roller, keep the permanent tensioning force of sticky tape under the effect of weight stone roller. The utility model discloses a size of belt tensioning power is adjusted in the change of weighing down the top height, weighs down tension and tightening force invariant that the stone roller tensioning can make the belt to by oneself tensioning, no matter the belt is unloaded and fully loaded, can not change the tension of belt, has stopped the belt effectively and has taken absolutely and sliding accident, has guaranteed rubber belt conveyor's normal operating.
Description
Technical field
This utility model is related to mine rubber band conveyer.
Background technology
At present, underground coal mine exploiting field rubber conveyer is designed with tensioner, and the effect of tensioner is：1st, make conveyer belt
Normal pressure is formed on cylinder driving, it is ensured that drive cylinder transmit enough frictional tractions.2nd, ensure conveyer belt slack list
There are enough tensile forces, prevent the conveyer belt in startup or operation from driving skidding on cylinder.3rd, ensure conveyer belt to from
There are enough tensile forces at point, sag when limit transport band is loaded between carrying roller prevents conveyer belt undue pine in idlers pitch
Relax and lose flute profile and cause belt deflection.4th, the elastic elongation and plastic elongation of conveyer belt are compensated.5th, can for plant maintenance,
Conveyer belt is changed and is repaired and provides necessary stroke.6th, when in long belt conveyor, reduction starts, brakes in conveyer belt
The dynamic load of appearance.
Current tensioner is generally tensioned prop drawer formula, and construction is as shown in Figure 1.It is to be provided with a pair in fuselage afterbody
Cylinder, it is belt tensioning drum 3 that one is bend pulley 2 one, and belt tensioning drum 3 is on sport car 6；It is this tensioning prop drawer formula be
Fixed, i.e., the steel wire rope 4 of sport car 6 is tensioned, and prop drawer 5 is direct to be tensed.As rubber conveyer is under unloaded and case of heavy load
Required tensile force is different from, and we accurately cannot be measured to tensile force at this stage, for tensile force control entirely with
Experience is judging；Tensioning prop drawer 5 after tightening belt, belt it is unloaded with heavy duty when all keep as tensile force.This
Sample not only reduces the service life of belt, and excessive tensile force can easily cause belt broken belt, adhesive tape accident stress
Shi Buneng plays cushioning effect, and broken belt accident also easily occurs.When adhesive tape fatigue elongation, tension force are less than normal, belt haulage chance goes out
Existing adhesive tape slipping phenomenon, particularly transporter open moment, it is impossible in time by empty belt tension, it is impossible to ensure two driving cylinders
While stress.
The content of the invention
To overcome the above-mentioned deficiency of existing fixed tensioner, this utility model to provide a kind of belt conveyor tail weight
Hammer tensioner.
A kind of belt conveyor tail gravity takeup, it is characterised in that set on the aircraft tail shelf of rubber conveyer
The aircraft tail cylinder for having track and sport car, rubber conveyer is arranged on sport car, aircraft tail cylinder is moved forward and backward on aircraft tail shelf,
The first fixed pulley in hanging at the top of belt conveyor tail rear, tail rear fixed installation tensioning prop drawer, are tensioned back again
Second fixed pulley is installed on post machine, one end of steel wire rope is pulled on sport car, the steel wire rope other end bypass the second fixed pulley and
Fix falling mound after first fixed pulley again, adhesive tape perseverance expanding force is kept under falling mound effect.
Good effect of the present utility model is, by the size changed to adjust belt tension for falling top height, falling mound
Tensioning can make the tension force and tightening force of belt constant, and voluntarily can be tensioned, and no matter belt is unloaded and fully loaded, to belt
Tension force has effectively prevented belt broken belt and skidding accident all without change, it is ensured that the normal operation of rubber conveyer.

Fig. 2 is the schematic diagram of this utility model embodiment.
Marginal data：1- aircraft tail cylinders, 2- bend pulleys, 3- belt tensioning drums, 4- steel wire ropes, 5- tensioning prop drawers, 6- run
Car, 7- falling mounds, 8- tracks, the first fixed pulleys of 9-, the second fixed pulleys of 10-.
Specific embodiment
As shown in Fig. 2 a kind of belt conveyor tail gravity takeup, is set on the aircraft tail shelf of rubber conveyer
The aircraft tail cylinder 1 for having track 8 and sport car 6, rubber conveyer is arranged on sport car 8, and aircraft tail cylinder 1 can be moved on aircraft tail shelf in front and back
It is dynamic, then the first fixed pulley 9 in hanging at the top of belt conveyor tail rear, tail rear fixed installation tensioning prop drawer 5,
Second fixed pulley 10 is installed on tight prop drawer 5, one end of steel wire rope 4 is pulled on sport car 6,4 other end of steel wire rope bypasses the
Falling mound 7 is fixed again after two fixed pulleys 10 and the first fixed pulley 9, and adhesive tape perseverance expanding force is kept in the case where falling mound 7 is acted on.
Claims (1)
1. a kind of belt conveyor tail gravity takeup, it is characterised in that it is on the aircraft tail shelf of rubber conveyer
