Description
Technical field
The present invention relates to a kind of devices for detecting SQ-1200 endless rope series tractor steel wire rope initial tension.
Background technology
SQ-1200 endless rope series tractor is widely used in underground coal mine, it the advantages of be that transportation range is long, applicable elements are wide, section
About human resources.New edition《Safety regulations in coal mine》（2016）The SQ-1200 endless rope series tractor that claims in 390th article must have
Steel wire rope tension declines protection, it is therefore desirable to which the protection is studied and applied.
In SQ-1200 endless rope series tractor actual application, the tensile force that theoretically steel wire rope is each put is difference,
And as pulling vehicle is in dynamic change.Therefore, the tensile force of somewhere steel wire rope how is fast reliably detected, and
It determines to need tight rope operation when steel wire tensioning power drops to a certain numerical value, is the difficult point of execute-in-place.
In October, 2016, when carrying out upgrading investigation to my ore deposit SQ-1200 endless rope series tractor, discovery does not have in the market
There is approved product steel wire tensioning power to decline protection.Current each manufacturer is all ground for tensile force decline protection
Hair, one kind is mechanical Weight type, and tensile force is provided for steel wire rope using weight, and loading position switchs on swelling device, plays
Tensile force declines protective effect.Which needs counterweight more, and required installation space is larger, increases unsafe link.
Invention content
The purpose of the present invention is to provide one kind can intuitively show steel wire rope initial tension, and safe and reliable detection continuous rope connects
The device of continuous tractor steel wire rope initial tension.
A kind of device for detecting SQ-1200 endless rope series tractor steel wire rope initial tension of the present invention, including quiet wheel, pressure measurement driving wheel, pressure
Dependent sensor, plc modules and fixed seat, the quiet wheel have 2, and on the same line, the pressure measurement driving wheel is mounted on 2 for installation
The top position in the centre of the quiet wheel, the voltage sensitive sensor are mounted on the pressure and survey on the axis pin of driving wheel, the plc modules
It is connect with the voltage sensitive sensor, the analog signals that voltage sensitive sensor exports is handled, digital output is converted to and arrives
Digital display tube is shown, while can be compared measured value and setting numerical value, and externally export a pair of switches amount,
The fixed seat is for fixing the quiet wheel and the pressure measurement driving wheel, and when onsite application can installation chassis.
The invention also includes the installation sites of tension tester, and according to use experience, which is preferably mounted on day
The gallery region of normal tight rope operation, the gallery region near tail wheel can be considered using tail wheel oil cylinder tight rope for some.
The present invention can continue to monitor steel wire tensioning power size, the main initial tension for choosing steel wire rope of the present invention（And sky
Tension during load）As detection project, when initial tension testing number value is reduced to calculated minimum, tight rope operation is needed, in addition,
Steel wire rope maximum initial tension is rule of thumb set as to 1.2 times of calculated value；Work as initial tension（With tension during zero load）Less than setting
During definite value, which realizes alarm by external circuits and winch is forbidden to run, and during more than the upper limit, only alarms.
For the elasticity and plasticity deflection for steel wire rope of dynamically attracting deposit, SQ-1200 endless rope series tractor be generally designed weight or
The swelling device of other forms can be used cooperatively with the present invention, need suitably to correct the numerical value of initial tension, usually
The tension value of weight offer is provided.
SQ-1200 endless rope series tractor in use, needs often to tighten steel wire rope, is to use hand by rule of thumb every time
Draw cucurbit or other modes tensioning, initial tension is small to be easily caused steel wire rope and skid on roller, the big deformation for increasing steel wire rope
And abrasion, after steel wire rope initial tension size determines, under conditions of friction coefficient is certain, endless rope winch maximum driving power is just
It determines.
A kind of device for detecting SQ-1200 endless rope series tractor steel wire rope initial tension of the present invention, the tensile force of steel wire rope can be intuitive
Display；It is capable of the tensile force of the dynamic reflection pilled-in selvedge and slack list steel wire rope in SQ-1200 endless rope series tractor operational process, tightly
The tensioning force difference of side and slack list is exactly the effective traction of winch, reflects the hoisting power of winch indirectly；It is electrodeless by detecting
The initial tension of rope continuous drafter steel wire rope, so as to quantitatively determine maximum pulling capacity, so as to play under steel wire tensioning power
The effect of protection is dropped, securely and reliably.
The device for detecting SQ-1200 endless rope series tractor steel wire rope initial tension a kind of to the present invention is made into one below in conjunction with the accompanying drawings
Walk explanation.
