Description
Technical field
The utility model relates to thermoelectric device technical fields, more specifically, being related to a kind of limit walking dress of sampling vehicle
It sets.
Background technique
Strap sampling machine is the first important link of gathering and processing coal sample, frequently takes coal back and forth automatically by sampling vehicle.Every time
The coal taken in sampling vehicle from belt is uneven or even heavy toward a lateral deviation, and so as to cause sampling vehicle, deflection is shaken during the motion
It shakes；Due to the inductive switch that limiting device uses, general distance of reaction is 8CM or so, and the sampling vehicle that deflection is rocked easily is hit
Bad inductive switch and interrupt sampling；When limiting device is switched using mechanical collision formula, due to frequently sampling, mechanical limit switch
It can fatigue damage, similarly influence equipment reliability service by long-term collision.
Utility model content
In order to overcome the technical drawbacks described above, the utility model provides a kind of limit running gear of sampling vehicle.
To achieve the above object, the utility model uses following technical scheme:
A kind of limit running gear of sampling vehicle, including stepper motor, shaft coupling, driving shaft, drive sprocket, chain, from
The output shaft of movable sprocket, driven shaft and sampling vehicle, stepper motor is connected with driving shaft by shaft coupling, is provided with master on driving shaft
Movable sprocket, drive sprocket are connected with driven sprocket by chain, and driven shaft is provided on driven sprocket, and the top welding of chain is solid
Surely there is sampling vehicle, ring flange is fixed on the driven shaft on the outside of the driven sprocket, detection hole, ring flange are offered on ring flange
Outside be provided with inductive switch fixed frame, inductive switch fixed frame is welded on strap sampling machine body；The inductive switch
Mounting hole is offered on fixed frame, high-frequency induction switch is installed in mounting hole, and high-frequency induction switchs on alignment flange disk wherein
One detection hole.
Further, the quantity of the detection hole is 8, centered on the center of circle of ring flange, is evenly arranged on ring flange.
Further, the high-frequency induction switch is 8cm at a distance from detection hole.
The beneficial effects of the utility model are: the present apparatus can effectively control the limit walking of sampling vehicle, significantly drop
The failure rate of low limiting device, reduces component wear, improves equipment dependability.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, as shown in Figure 1-3, a kind of limit running gear of sampling vehicle, including stepper motor 1, shaft coupling 2, master
The output shaft of moving axis 3, drive sprocket 4, chain 5, driven sprocket 6, driven shaft 7 and sampling vehicle 8, stepper motor 1 passes through shaft coupling 2
It is connected with driving shaft 3, drive sprocket 4 is provided on driving shaft 3, drive sprocket 4 is connected with driven sprocket 6 by chain 5, driven
Driven shaft 7 is provided on sprocket wheel 6, the top of chain 5 is welded with sampling vehicle 8, on the driven shaft 7 in 6 outside of driven sprocket
It is fixed with ring flange 9, detection hole 10 is offered on ring flange 9, the outside of ring flange 9 is provided with inductive switch fixed frame 11, sense
Inductive switch fixed frame 11 is welded on strap sampling machine body；Mounting hole 13 is offered on inductive switch fixed frame 11, is installed
Be equipped in hole 13 high-frequency induction switch 12 (TURCK NI8-M18-AD4X), on 12 alignment flange disk 9 of high-frequency induction switch its
In a detection hole 10；
Wherein the quantity of detection hole 10 is 8, centered on the center of circle of ring flange 9, is evenly arranged on ring flange 9；
Wherein high-frequency induction switch 12 is 8cm at a distance from detection hole 10.
In the present embodiment, after sampling vehicle 8 is automatically brought into operation unlatching, stepper motor 1 drives drive chain by driving shaft 3
4 rotation of wheel, drive sprocket 4 drive sampling vehicle 8 to move by chain 5；At the same time, drive sprocket 4 is driven driven by chain 5
Sprocket wheel 6 rotates, and driven sprocket 6 drives ring flange 9 to rotate by driven shaft 7, and high-frequency induction switch 12 is by detection hole 10, constantly
Collect the rotary pulsed of ring flange 9, then pass the signal to Sampling Machine PLC.
When sampling vehicle 8 rotates in the forward direction sampling, Sampling Machine PLC is sensed to stop after the umber of pulse of high-frequency induction switch 12 is 80
Only, it is delayed 5 seconds after sampling, automatic reverse rotary unloading sample；It reads after umber of pulse is 80 and stops, delay carries out next after 300 seconds
Take turns the coal sampling period.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of them part may be made, and belong to the utility model
Protection scope within.
