Abstract
The utility model relates to a scrape trigger and prevent chain rupture protection device, the rotary integrating sphere includes a fixed support, the top installation proximity switch of fixed bolster, proximity switch transmission signal is to PLC, the left side position installation touching mechanism of fixed bolster, touching mechanism includes contact rod, contact rod's middle part rachis movable mounting in the left side position of fixed bolster, buckle its tip of back and be located the place ahead of proximity switch in contact rod's upper portion, under the normality, contact rod is in vertical state and its lower extreme has the chain 2 -3cm who scrapes trigger aircraft nose chain and take turns to. The utility model relates to a rationally, the device is mainly through the action of the touching drive proximity switch of mechanism to shutting equipment parks.
Description
Technical field
The utility model relates to the auxiliary device of underground coal mine transportation equipment scrapper conveyor, is specially a kind of scrapper conveyor chain broken prevention fender guard.
Background technology
Slat conveyer is the modal transportation device in colliery, in routine use, maintenance is larger, and accident rate is higher, often easily occur jumping the phenomenon such as tooth, de-chain, as equipment belt load running finds not in time, very easily cause scraper plate stretch bending, horse-shoe collar or chain such as to break at the accident, during repairing accident minimum more than 4-5 hour, have a strong impact on equipment driving efficiency.
Scrapper conveyor occurs to jump the phenomenon such as tooth, de-chain mainly at machine head chain wheel place, as long as these two kinds of faults of energy Timeliness coverage, just effectively can avoid the generation of chain rupture.
Summary of the invention
The utility model mainly through self-control chain broken prevention protection mechanism, when there is to jump tooth and de-chain phenomenon in scrapper conveyor can action immediately, avoid the generation of chain rupture, reduce accident rate.
The utility model adopts following technical scheme to realize:
A kind of scrapper conveyor chain broken prevention fender guard, comprises fixed support, and proximity switch is installed in described support bracket fastened top, and described proximity switch signal transmission is to PLC; Described support bracket fastened left-hand portion installs touching mechanism, and described touching mechanism comprises touching bar, and the middle ends axle of described touching bar is movably installed in support bracket fastened left-hand portion, and after the top bending of described touching bar, its end is positioned at the front of proximity switch; Under normality, touching bar is in vertical state and its lower end has the chain 2-3cm on scrapper conveyor machine head chain wheel.
Under normality, as in Fig. 1, solid line represents, touching bar keeps vertical state under gravity, and proximity switch is failure to actuate.When scrapper conveyor occurs to jump tooth or de-chain; the moment that chain departs from sprocket wheel makes touching bar rotate along its middle ends axle anticlockwise direction, as in Fig. 1, dotted portion represents, then touches the upper end kink of bar near proximity switch; proximity switch sends signal immediately to PLC, and then locking scrapper conveyor is shut down.
Through above-mentioned to the transformation of scrapper conveyor head section after, result of use is very good, and jumping tooth and de-chain phenomenon can action immediately, avoids the generation of chain rupture.
The utility model is reasonable in design, and this device drives proximity switch action mainly through touching mechanism, thus interlock stops.
Accompanying drawing explanation
Fig. 1 represents operating principle schematic diagram of the present utility model.
In figure, 1-scrapper conveyor machine head chain wheel, 2-chain, 3-fixed mount, 4-proximity switch, 5-touches bar, 6-middle ends axle.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
A kind of scrapper conveyor chain broken prevention fender guard, as shown in Figure 1, comprises fixed support 3, and proximity switch 4 is installed in the top of described fixed support 3, and described proximity switch 4 signal transmission is to PLC; The left-hand portion of described fixed support 3 installs touching mechanism, described touching mechanism comprises touching bar 5, the middle ends axle 6 of described touching bar 5 is movably installed in the left-hand portion of fixed support 3 by modes such as bearing or free-running fit installations, after the top bending of described touching bar 5, its end is positioned at the front of proximity switch 4; Under normality, touching bar 5 is in vertical state and its lower end has the chain 2-3cm on scrapper conveyor machine head chain wheel 1, and its top folded end is away from proximity switch 4.
At the machine head chain wheel place mounting and fixing bracket of slat conveyer, the large I of support is according to the on-the-spot practical adjustments of scrapper conveyor size.Then install touching mechanism, utilize round steel and band iron to make the touching mechanism of a jumping tooth and de-chain, the distance touching chain on mechanism and sprocket wheel is 2-3 centimetre and is advisable, and cross conference and cause touching insensitive, too small meeting causes action too sensitive.Proximity switch is installed in support bracket fastened top, and the signal of this proximity switch returns in PLC, and by touching, mechanism drives proximity switch action, realizes locking and stops.Mainly through self-control chain broken prevention protection mechanism, jumping tooth and de-chain phenomenon can action immediately, avoids the generation of chain rupture, reduces accident rate.In-site installation is simple, and other there is no particular/special requirement, and using method is simple.
It should be noted last that; above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail with reference to the utility model embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement; do not depart from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
