Description
Technical field
The utility model belongs to a kind of detection technique in the sewage treatment area, particularly a kind of loose chain pick-up unit that the chain of mechanical grille is detected.
Background technology
Mechanical grille is mounted in a kind of plant equipment of blocking dirt, removing contamination that integrates at power station, intakes of pumping station place, be mainly used in the floating thing in the interception sewage, and rely on the chain drive revolution tooth harrow that self rotates that the floating thing of tackling is dragged for up, focus on then.Chain is after long-time running, because pin-and-hole weares and teares, the diameter change causes the whole piece chain elongated greatly, the chain tenesmus is scratched easily, breaks chain when serious.Judge now chain whether the method for loose chain be by artificial arrive water channel down at the bottom of, bend to observe the loosening situation of chain, judge the loose chain situation of mechanical grille, so just increased labour intensity and cost of labor, and production efficiency is low, moreover, often can not cut off the water supply because of the water channel of producing that needs, cause in time to find the loosening situation of mechanical grille bottom chain, and the damage chain makes that detecting quality can not get guaranteeing.
The utility model content
The utility model is big at the labour intensity that manual detection pine chain in the prior art causes, production efficiency is low and manually can not in time find the loosening problem that causes chain to damage of chain, a kind of loose chain pick-up unit is provided, this device can detect the loosening situation of wearing and tearing of mechanical grille chain easily, solve the serial problem that manual detection pine chain brings, and improved production efficiency.
The technical solution of the utility model is as follows:
A kind of loose chain pick-up unit of mechanical grille, it is characterized in that, be included in the inner postive stop baffle that is provided with of mechanical grille, connecting rod, stretching device, induction installation and near switch, described postive stop baffle is arranged at the bottom of the bottom chain revolution circumference of mechanical grille, and is articulated on the grid frame; The fixedly connected postive stop baffle of one end of described connecting rod and be positioned at the homonymy of postive stop baffle deflection, an end of the other end and stretching device is hinged, and the other end of stretching device is fixedly set in grid frame upper end; Described induction installation is fixedly installed on the stretching device and with the stretching campaign of stretching device, the movement locus of induction installation is provided with near switch, describedly is connected with warning device near switch.
Described stretching device comprises spring and pull bar, and an end of described spring is fixedly set in grid frame upper end, an end of the fixedly connected pull bar of the other end, and the other end of described pull bar and the other end of connecting rod are hinged, and described induction installation is fixedly installed on the pull bar.
Described induction installation is a sensing chip.
The arranged outside of described postive stop baffle hinged place has block.
Technique effect of the present utility model is as follows:
The loose chain pick-up unit of the mechanical grille that the utility model relates to, bottom at the bottom of mechanical grille chain revolution circumference is provided with a postive stop baffle, and this postive stop baffle can be around pin joint deflection, after chain is loosening, the sagging bottom of chain can be gradually near positive stop block, until contact and drive positive stop block deflection with positive stop block, and then drivening rod rotation, connecting rod is by the motion of pin joint pulling stretching device, at this moment the induction installation on the stretching device just near near switch, makes to produce feedback signal near switch, can drive warning device and report to the police, the prompting chain is loosening, detects thereby finish loose chain.The utility model is delivered to the top of mechanical grille with the loosening situation of chain under water by postive stop baffle, connecting rod and the stretching device that is provided with, and can drive the warning device warning, can remind and in time chain equipment be overhauled, and protects equipment effectively.Could manually at the bottom of water channel, observe the loosening situation of chain down after having avoided needing mechanical grille to quit work in the prior art; alleviated labour intensity; improved production efficiency; and this device can in time detect the loosening abrasion condition of mechanical grille bottom chain easily; avoided the untimely chain that brings of artificial discovery to damage problem; make that detecting quality is guaranteed, prevent that chain from becoming flexible the back and being broken by accident, and then can effectively protect mechanical grille.
Arranged outside block in the postive stop baffle hinged place can be guaranteed that block turns round circumferencial direction deflection around pin joint along chain, thereby drive the motion of subsequent parts, finishes loose chain and detects.
Description of drawings
Fig. 1 is the structural representation of the loose chain pick-up unit of the utility model preferred mechanical grid.
Each label lists as follows among the figure:
1-grid frame; The 2-block; The 3-connecting rod; The 4-postive stop baffle; The 5-chain; The 6-pull bar; 7-is near switch; The 8-sensing chip; The 9-spring; The 10-warning device.
Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is the structural representation of the loose chain pick-up unit of the utility model preferred mechanical grid, be included in the inner block 2 that is provided with of mechanical grille, connecting rod 3, postive stop baffle 4, pull bar 6, near switch 7, sensing chip 8, spring 9 and warning device 10, postive stop baffle 4 is arranged at the bottom of the bottom chain 5 revolution circumference of mechanical grille, and be articulated on the grid frame 1, chain 5 gyratory directions shown in Fig. 1 are clockwise revolution as shown by arrows, so postive stop baffle 4 can be around the counterclockwise deflection of pin joint that is hinged on the grid frame 1, simultaneously for guaranteeing the yawing moment of postive stop baffle 4, arranged outside block 2 in postive stop baffle 4 hinged places.One end of connecting rod 3 is fixedly connected postive stop baffle 4 from the left side, the preferred spring 9 of present embodiment links to each other as the other end of stretching device with connecting rod 3 with pull bar 6, be specially: an end of spring 9 is fixedly set in grid frame 1 upper end, one end of the fixedly connected pull bar 6 of the other end, the other end of the other end of pull bar 6 and connecting rod 3 is hinged.On pull bar 6, be welded with sensing chip 8 as induction installation, it can certainly be other induction installation, connecting rod 3 drives pull bar 6 motions, spring 9 stretches, sensing chip 8 and pull bar 6 move together, be provided with near switch 7 as Fig. 1 lower end near sensing chip 8 on sensing chip 8 movement locus, connect warning device 10 near switch 7.
