Abstract
The utility model belongs to band conveyer chute blocking detection field especially relates to a chute blocks up mechanical hold back, sets up the blocking detection opening part on the perpendicular on one side of the band conveyer chute, bump door and normal close travel switch including bumping door frame, putty, bump the door frame, install and detecting the opening periphery, the putty bumps the door, and bumps the door frame and matches, and the putty bumps the upper end of door and installs in the upper end of bumping the door frame, normal close travel switch installs and is bumping the nearly lower extreme in door frame right side, and normal close travel switch establishes ties with band conveyer's master switch, works as the chute the inside and takes place material choking, and the material touching putty of jam bumps the door, and the putty bumps the door and outwards touches normal close travel switch, and then the drive master switch carries out the shut -down operation to whole band conveyer. The utility model discloses can carry out effectual detection and detect the reaction sensitivity, the strong and simple structure of interference killing feature the material condition of chute.
Description
Technical field
The utility model belongs to belt conveyor chute blocking detection field, more particularly to a kind of chute blocking machinery stops
Device.
Background technology
During belt conveyor conveying material, often there is feed blocking phenomenon in chute, if found not in time,
The material of blocking is cumulative eventually to affect the normal operation of induction system, or even damages.It is defeated to belt in existing technology
Detected using electronic type more than the detection for sending machine chute blocking, be related to signal, sensor etc., but such detection means is anti-
Interference performance is poor, it is impossible to very implement effective detection, and complex structure, and manufacturing cost is high.
Utility model content
To solve problems of the prior art, the utility model provides a kind of detection and is quick on the draw, antijamming capability
Strong and simple structure, the chute blocking mechanical stop of low cost of manufacture, mechanically detecting belt conveyor chute
Stopping state, when there is feed blocking, stops in time machine, it is to avoid equipment damage.
For achieving the above object, the utility model provides a kind of chute blocking mechanical stop, is arranged on Belt Conveying
On the vertical plane of machine chute side at jam detection opening, including door frame, putty is touched door and normally closed travel switch are touched；
Door frame is touched, installed in detection opening periphery；
Putty touches door, matches with door frame is touched, and putty touches the upper end of door and is arranged on the upper end for touching door frame；
Normally closed travel switch, installed in touching on door frame, connects with the master switch of belt conveyor；
When chute the inside occurs feed blocking, the material touching putty of blocking touches door, and putty touches door and is displaced outwardly touching often
Travel switch is closed, and then drives master switch to stop operation whole belt conveyor.
Further, normally closed travel switch touches the right edge lower end of door installed in putty.
Further, touch door frame and be provided with limited block, the location matches of the position of limited block and normally closed travel switch.
Further, spacing number of blocks is two, is separately mounted to touch the both sides lower end of door frame, wherein right side is spacing
Block, installed in the left side of normally closed travel switch.
Further, the upper end of door is touched in the upper end and putty of touching door frame, takes being articulated and connected therebetween.
The utility model is compared with prior art：Structure is simpler, cheap for manufacturing cost, and using mechanical inspection
Survey and strong antijamming capability is set, be quick on the draw, misoperation is not detected, as long as can be detected when chute is blocked
Arrive.
Description of the drawings
Fig. 1 positions structural representation of the present utility model.
Fig. 2 is utility model works schematic diagram.
Fig. 3 is limited block and normally closed travel switch position relationship schematic diagram.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this reality
With new, it is not used to limit the utility model.
A kind of chute blocking mechanical stop, is arranged on jam detection opening on the vertical plane of belt conveyor chute side
Place, as shown in figure 1, touching door 2 and normally closed travel switch 3 including door frame 1, putty is touched；Touch door frame 1 to design for quadra,
Size is matched with the detection opening of chute, is placed outside detection opening；Putty touches the size shape of door 2 and touches door frame 1
Match somebody with somebody, putty touches the top of door 2 and is hingedly mounted on the top for touching door frame 1.The master switch of normally closed travel switch 3 and belt conveyor
Series connection, installed in the right edge lower end for touching door frame 1, when the benefit installed in lower end is that putty touches door 2 and is displaced outwardly, putty is touched
Door 2 most can soon encounter below normally closed travel switch 3.As shown in Fig. 2 when chute the inside occurs feed blocking, the thing of blocking
Outwards expansion touching putty touches door 2 to material so that putty touches and normally closed travel switch 3 is touched after door 2 is displaced outwardly, and then controls whole
Belt conveyor is stopped operation, the mechanical timely detection realized to chute material stopping state, and belt conveyor stops
Afterwards, operating personnel can be processed the material for blocking.
Because when material is blocked, outwards the material of expansion causes putty to touch door 2 to be displaced outwardly touching normally closed stroke
Switch 3, belt conveyor starts to taper off operation this moment, but because the machine for operating has inertia, it is impossible to stop at once, be
Prevent from the material for blocking from continuing to expand against putty and touch door 2 to continue outwards to damage normal to the outside power of 3 one, normally closed travel switch
Travel switch 3 is closed, we are provided with limited block 4 on door frame 1 is touched, the position of the position of limited block 4 and normally closed travel switch 3
Match somebody with somebody.Here the quantity of limited block 4 is preferably set to two by us, and first limited block 41 is arranged on the left side for touching door frame 1
Side lower end, second limited block 41 of limited block 42 and first is symmetrically mounted on the right edge lower end for touching door frame 1, and second
Limited block 42 is mounted side by side on the left side of normally closed travel switch 3.As shown in figure 3, the head end of normally closed travel switch 3 touches door from putty
2 head end for being less than limited block 4 apart from d1 touches distance d2 of door 2 from putty, and when putty touches door 2 normally closed travel switch is first touched
After 3, putty is touched when door 2 continues to be displaced outwardly and just to stop spacing by the limited block 4 for touching 1 liang of side of door frame, it is to avoid damage normal
Travel switch 3 is closed, limit switch 4 serves the effect of a position limitation protection to normally closed travel switch 3.
The above, preferred embodiment only of the present utility model, protection domain of the present utility model is not limited to this, appoints
What those skilled in the art should be covered in model of the present utility model in any conversion or replacement disclosed by the utility model
Within enclosing.
