Abstract
The utility model provides a kind of sideslip drawstring combination switch, including housing and microswitch, two trigger wheels up and down are provided on the microswitch, microswitch side is provided with vertical rod cam, connection reaches the sideslip outside housing and founds rod on vertical rod cam, the other side of microswitch is provided with drawstring cam, connection stay cord rotary shaft on drawstring cam, and drawstring rotary shaft reaches on the outside of housing.The sideslip drawstring combination switch integrates deviation switch and pull switch, reduces the quantity of the emergency stop protection switch on belt feeder, has saved cost.
Description
Technical field
The utility model relates to the belt conveyors in a kind of coal mine machinery, more particularly to a kind of sideslip drawstring
Combination switch.
Background technique
Belt feeder sideslip and emergency stop protection is independent deviation switch and two kinds of pull switch at present, and deviation switch is every
One group is filled every 50 meters, pull switch fills one group every 30 meters, for one 1000 meters of underground coal mine belt feeder, it is necessary to 20 groups
Deviation switch and 30 groups of pull switches, dosage is big, and every switch has wiring, and wiring is various, expensive, by every group
600 yuan of calculating, it is necessary to spend 30,000 yuan.
Summary of the invention
In order to solve the problems, such as above-mentioned technology, the utility model provides a kind of sideslip drawstring combination switch.
The utility model is achieved through the following technical solutions: a kind of sideslip drawstring combination switch, including housing and micro-
It is dynamic to switch, it is provided with two trigger wheels, microswitch side up and down on the microswitch and is provided with vertical rod cam, founds rod cam
Upper connection reaches the sideslip outside housing and founds rod, and the other side of microswitch is provided with drawstring cam, connects on drawstring cam
Drawstring rotary shaft, drawstring rotary shaft reach on the outside of housing.
In above scheme, the pivot center of the vertical rod cam and drawstring cam differs 90 ° in the horizontal plane.
A kind of sideslip drawstring combination switch of the utility model compared with prior art, the beneficial effect is that:
The sideslip drawstring combination switch integrates deviation switch and pull switch, can not only do deviation switch with but also can draw
Cord switch is used, and the specification type of switch is reduced, and decreases the usage quantity of switch, and installation time wiring work can save
Half the time, remarkable in economical benefits, wide market.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model sideslip drawstring combination switch.
Fig. 2 is the left view of Fig. 1.
In figure: 1. housings, 2. vertical rod cams, 3. sideslips found rod, trigger wheel on 4., 5. microswitches, 6. drawstring rotary shafts,
7. drawstring cam, 8. lower trigger wheels.
Specific embodiment
The utility model sideslip drawstring combination switch is further described with specific embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model sideslip drawstring combination switch, and Fig. 2 is the left view of Fig. 1.It, should in figure
Sideslip drawstring combination switch, including housing 1 and microswitch 5 are provided with two 4 Hes of trigger wheel up and down on the microswitch 5
8, microswitch upside is provided with vertical rod cam 2, and connection reaches the sideslip outside housing and founds rod 3 on vertical rod cam 2, and fine motion is opened
The downside for closing 5 is provided with drawstring cam 7, and connection stay cord rotary shaft 6 on drawstring cam 7, drawstring rotary shaft 6 reaches outside housing 1
Side.The pivot center of vertical rod cam 2 and drawstring cam 7 differs 90 ° in the horizontal plane.
When work, because the belt deviation on belt feeder touches vertical rod, the vertical rod cam 2 below vertical rod can encounter upper triggering
Wheel 4, so that the movement power-off of microswitch 5, forces belt to stop；And when operator pulls drawstring, drawstring rotary shaft 6 rotates
Lower trigger wheel 8 can be encountered, force the movement power-off of microswitch 5.
The sideslip drawstring combination switch integrates deviation switch and pull switch, reduces the emergency stop protection on belt feeder
The quantity of switch, has saved cost.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation be not intended to limit the utility model although the utility model has been disclosed with preferred embodiment as above, it is any ripe
Know professional and technical personnel, do not departing within the scope of technical solutions of the utility model, when using the disclosure above method and
Technology contents make a little change or the equivalent embodiment for being modified to equivalent variations, but all without departing from the utility model technology
The content of scheme, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
