Description
Technical field
The invention belongs to a kind of colliery downhole equipment, especially a kind of unloading roller reserve protection.
Technical background
Coal Transport generally uses steel belt conveyor to carry out long range, heavy grade transport.Its rubber conveyer
Unloading roller be one of maximum component of stress, often will appear because unloading roller damage caused by rubber conveyer destruction
And cause to interrupt the generation of production accident, how to prevent unloading roller damage to be just particularly important.Existing underground sub-inclined shaft
DTL100/63/2 × 315S type rubber conveyers（The gradient where it is installed is 16 degree Ban, and length is 596 meters）Unloading roller go out
Existing cylinder is snapped with a side neck hub weld bond, causes unloading roller cylinder to be detached with this side neck hub, cylinder rises with another side neck hub one
It is raw to swing, it causes the steel cable belt run on unloading roller to crack, causes the rubber conveyer out of service, correlation is adopted
Coal working face stops production；The repairing for needing 4 shifts of used time replaces the unloading roller of damage and replaces 60 meters of steel cable belts,
Then adjusted to reach rubber conveyer serviceable condition；General steel belt conveyor is only responsible for coal working face
It produces coal transport, produces coal transport task if being responsible for two coal working faces, full mine halt production accident will be caused；Even make
At the loss of bigger.When the above damage occurs for unloading roller, with the operation of rubber conveyer steel cable belt is generated
Tearing etc. damage, the degree of damage is not both to be determined according to the time of discovery, and caused loss is different, because
This can find to shut down in time as early as possible, can avoid or reduce the loss of steel cable belt as far as possible, be to ensure adhesive tape conveying
The crux of the safe operation of machine.Therefore, it is necessary to which corresponding measure is taken to solve the problems, such as this.
Invention content
The object of the present invention is to provide a kind of unloading roller reserve protections：It can fully monitor when unloading roller is run
Safe condition goes wrong and alarm and shuts down, high sensitivity, securely and reliably, avoids and occurs when unloading roller exception
Rubber conveyer damages, and has prevented generation and the economic loss of industrial accident.Eliminate rubber conveyer unloading roller meaning
Foreign affairs so occur harm；And it is simple in structure, it is easy to maintain.
Technical solution provided by the invention：Including unloading roller, unloads carrier beam, fixes beam on rear side of unloading roller, it is characterized in that：
It is fixed on rear side of unloading roller and assembles two mining misalignment sensor fixed frames on beam in an axial direction, fixed in mining misalignment sensor
Be fixedly connected mining misalignment sensor on frame；There is the feeler lever of micro spacing to be fixedly connected on two fixed sleevings with unloading roller
On, two fixed sleevings are set on two mining misalignment sensors；
In unloading in carrier beam for unloading roller both ends, it is located at cylinder hub outer circle protruding parts on rear side of unloading roller and travel switch, row is installed
Journey switch touch wheel is close to unloading roller cylinder hub outer protruding parts.
The positive effect of the present invention：Safe condition when unloading roller operation can be fully monitored, is gone wrong and alarm
And shut down, high sensitivity, securely and reliably, the rubber conveyer damage occurred when unloading roller exception is avoided, safety has been prevented
The generation of production accident and economic loss.The harm for eliminating the contingency of rubber conveyer unloading roller and occurring；And it ties
Structure is simple, easy to maintain.

Specific implementation mode
Concrete structure is as follows：
The steel cable belt damage feelings that protective device provided by the invention may cause for unloading roller damaged condition difference
Condition is also different, designs corresponding two kinds of protective devices：
（1）, see Fig. 1-4, fixed in the rear side of unloading roller 1 and assemble two mining misalignment sensor fixed frame 5- on beam 5 in an axial direction
Setting fine tuning slot hole on 1, mining misalignment sensor fixed frame 5-1（See Fig. 5）, in the length of mining misalignment sensor fixed frame 5-1
It is bolted on hole and couples mining misalignment sensor 3；There is the feeler lever 2 of micro spacing to be fixedly connected on two with unloading roller
On fixed sleeving 6, two fixed sleevings 6 are set on the frizzen of two mining misalignment sensors 3.Two mining sideslips
The spacing of sensor 3 is 900 millimeters.Between on the anti-deviation sensor of fine tuning slot hole adjustment between feeler lever and unloading roller cylinder
Away from ensureing it i.e. does not influence effectively trigger feeler lever when rubber conveyer runs guarantee unloading roller rotary oscillation again, reaches
Drive anti-deviation sensor actuation.
In 1 rear side setting protection contact of unloading roller, when unloading roller generates rotary oscillation deformation because of damage, triggering
Contact is protected, protection contact is made to act, then control warning system is transmitted to by the protection circuit of connecting terminal and is alarmed simultaneously
It shuts down in time.
（2）, see Fig. 6,7, in unloading in carrier beam 4 for 1 both ends of unloading roller, be located at cylinder hub outer circle protrusion on rear side of unloading roller
Position installation travel switch 7,7 wheel trolley of travel switch is close to 1 hub outer of unloading roller protruding parts.
Protection contact is set in unloading roller both sides, when unloading roller generates play deformation in an axial direction because of damage, is touched
Hair protection contact, makes protection contact act, then is transmitted to control warning system by the protection circuit of connecting terminal and alarms
And it shuts down in time.
The control principle of protective device：
See Fig. 8, the model KJ161 types of the rubber belt conveyor protector now used, are the prior arts；It is including monitoring system
Using KJD30 displays embedded controller as core, driver is controlled by KDK8 type mining multifunctionals, KGV5 bus type emergency stops are closed
Lock-switch.
1, generated when unloading roller because of damage rotary oscillation deformation when, contact S3 or S4 action generate closure when, can will
The connecting terminal IN+ and IN- short circuits in emergency stop blocking device KGV5A in model KJ161 type belt conveyor protective devices,
To the protection circuit turn-on of emergency stop locking, forming circuit, then by signal transduction to the inside mainboard in KJD30 escopes,
Thus send out shutdown, alarm command gives KDK8 type guard boxs, execution sends out tearing and alarm signal and shuts down.
When 2, generating play deformation in an axial direction when unloading roller because of damage, when contact S1 or S2 action generate closure, meeting
Connecting terminal IN+ and IN- in emergency stop blocking device KGV5A in model KJ161 type belt conveyor protective devices is short
It connects, to the protection circuit turn-on of emergency stop locking, is formed into a loop, then by signal transduction to the inside master in KJD30 escopes
Plate, thus sends out shutdown, alarm command gives KDK8 type guard boxs, and execution sends out tearing alarm signal and shuts down.
After protection act, in the motion picture of the display screen display tearing protection icon flicker of KJD30, it is used as prompting
Service personnel searches and the foundation of handling failure.
