Abstract
The utility model relates to a derailing-warning protector for a large dedicated bulk cargo machine. The derailing-warning protector is characterized in that protection switches are respectively arranged on rail cleaners positioned on the northeast, southeast, northwest and southwest corners of the traveling gantry of the large machine. Each rail cleaner is provided with a cleaner support, which is movably connected with a wooden cleaning block; a protection switch bracket is arranged on the rail cleaner; and the protection switch is arranged on the protection switch bracket and connected with the wooden cleaning block by a hanging hook. Once the large machine is about to derail, the protection switches are pulled to act, and because the protection switches are connected in series with a control circuit for controlling sudden stop, which is arranged on the side of the traveling mechanism of the large machine, the derailing-warning protector can instantly stop the large machine and give an alarm, thus avoiding the occurrence of a derailing accident.
Description
Technical field
The utility model relates to a kind of traveling fender guard.Be particularly related to the derailed alarm protecting apparatus of a kind of large-scale bulk goods special-purpose machinery traveling.
Background technology
At present, the heap of harbour bulk goods deposits, withdraws the dress large-scale special-purpose machineries that adopt fixed track-movable within the specific limits more, as stocker, reclaimer, ship loader etc.The traveling fender guard of these big machineries is provided with generally that terminal operation is spacing, the terminal limit is spacing, both traveling coder of terminal backstop and traveling position sensor.In actual use, because big machine takes place and laterally oversteps the limit as perpendicular to track operation etc. in sinking, distortion or some special operation conditions of walking rails probably.Existing terminal operation is spacing, the terminal limit is spacing, terminal backstop prevents that just big machine direction along ng a path from going out away the three-level protective of line range.The traveling coder mainly is to measure line position, though dynamic, static warning of coder and protections such as observed reading and the excessive warning of actual value deviation are arranged, laterally overstepping the limit for big machine also is Zhuge afterwards.In case these minimum deadweights all have nearly 400 tons big machinery to take place laterally to overstep the limit, resume work very difficult.
Summary of the invention
The technical problems to be solved in the utility model is, manufactures and designs a kind ofly can prevent that large-scale bulk goods special-purpose machinery from the fender guard of laterally overstepping the limit taking place in the traveling process---the large-scale bulk goods special-purpose machinery traveling alarm protecting apparatus of overstepping the limit.
The technical scheme that the utility model adopted:
A kind of large-scale bulk goods special-purpose machinery (being called for short big machine) traveling alarm protecting apparatus of overstepping the limit; it is characterized in that: on the track cleaning of four angular positions in the northeast of large-scale bulk goods special-purpose machinery traveling door frame, the southeast, northwest, southwest; track cleaning is respectively installed a protection switch, and this protection switch is connected in series on the anxious control circuit that stops of large-scale bulk goods special-purpose machinery traveling pusher side control.
Track cleaning has the swabbing pig support, flexibly connects the cleaning wooden unit at the swabbing pig support; The protection switch support is arranged on the track cleaning, on the protection switch support protection switch is housed, connect by hook between protection switch and the cleaning wooden unit.
On large-scale bulk goods special-purpose machinery track cleaning protection switch is installed, this protection switch is connected in series on the anxious control circuit that stops of large-scale bulk goods special-purpose machinery traveling pusher side control.
On big machine track cleaning the position limitation protection switch is installed, this switch series is linked on the anxious control circuit that stops of big machine traveling pusher side control.In case big confidential overstepping the limit, its walking wheel will lift and swabbing pig will descend, thereby drives the limit switch action, and big machine will stop traveling immediately and send warning, to avoid the generation of derailment accident.
The utility model preceence and effect:
This apparatus structure is simple, and is cheap, can promptly produce protection before big machine is laterally overstepped the limit, and avoids taking place derailment accident.

Fig. 3 is among the anxious control circuit figure figure that stops of large-scale bulk goods special-purpose machinery traveling pusher side control: 1-swabbing pig support; 2-cleans wooden unit; 3-protection switch support; The 4-protection switch; The 5-hook;
The specific embodiment
A kind of large-scale bulk goods special-purpose machinery (being called for short big machine) traveling alarm protecting apparatus of overstepping the limit; on the track cleaning of four angular positions in the northeast of large-scale bulk goods special-purpose machinery traveling door frame, the southeast, northwest, southwest; track cleaning is respectively installed a protection switch 4 as shown in Figure 1, 2, and this protection switch is connected in series on the anxious control circuit (as Fig. 3) that stops of large-scale bulk goods special-purpose machinery traveling pusher side control.
As Fig. 1,2 track cleanings swabbing pig support 1 is arranged, flexibly connect cleaning wooden unit 2 at the swabbing pig support; Protection switch support 3 is arranged on the track cleaning, protection switch 4 is housed on the protection switch support, connect 5 by hook between protection switch and the cleaning wooden unit.
1. make, install swabbing pig
Every big machine has 4 swabbing pigs, be installed in the position, four angles (northeast, the southeast, northwest, southwest) of traveling door frame respectively, its swabbing pig structure such as Fig. 1,2, oblong cleaning wooden unit can be freely up and down in fixed mount, constantly contact to ensure, thereby play the effect of clearing up the obstacle on the track at any time with orbital plane.By on-the-spot actual the investigation, northeast, southeast corner swabbing pig can utilize, and northwest, two swabbing pigs in southwest corner can accurately not keep synchronously with the homonymy walking wheel owing to be installed in the rail clamping device outside, so can not utilize, must make swabbing pig again and it is installed in correct position.Swabbing pig is provided with the limit switch mounting bracket, installs the limit switch suspension member additional on the oblong cleaning wooden unit.During installation the universal switch contact is put into suspension member, and adjusting its actuating length is about 10mm, on the one hand for avoiding big machine vibration or misoperation during through the rail joints place, be the derailed necessary condition of guaranteeing big machine (amount of lifting must greater than walking wheel outside dimensions 25mm) precision maneuver before on the other hand.
2. realize defencive function (seeing anti-derail interconnecting wiring diagram)
In line with realizing alarm and protection, can save the principle of cable again.We are connected in series to fender guard on the anxious control circuit that stops of big machine traveling pusher side control in decision, timely alarm driver after the assurance switch motion to operator's compartment, and shut down rapidly, thereby avoid derailment accident to take place.
In February, 2007, we finished the installation of 7 derailed fender guards of large-scale bulk goods machinery traveling.Through field experiment, the big machine inertia in protection switch action back is distance travelled to be 200mm, satisfies requirement of shelter, and the energy actv. is avoided the generation of derailment accident.Consider that maintenance cost and stopping production after the collision damage; the accumulation benefit reaches more than 1,440,000 yuan; and 1200 yuan of every equipment less thaies of the development of this fender guard and erected cost, and this technology has important promotional value in overstepping the limit in that harbour big machinery traveling is anti-.
