Description
Technical field
Utility model relates to a kind of protective device, particularly a kind of modified mud scraper protective device.
Background technology
Existing Americanized mud scraper is to be made of scraper plate, chain, sprocket wheel, motor, monitoring system controller, detection probe etc.Its structure is that the two ends that are about 7.8 meters scraper plates are installed in respectively on the driving chain of sedimentation basin (long 115 meters, wide 8 meters, dark 4.5 meters) both sides, and drive the chain moving linearly by power chain, scraper plate constantly is transported to the mud at the bottom of the pond in the spoil disposal ditch (sees Fig. 1, Fig. 2).Scraper plate is to make shuttling movement in the sedimentation basin both sides in by two closed-loops being made up of a power wheel and three bend wheels, and synchronous operation must done in the both sides of scraper plate simultaneously.But when the driving chain of a certain side cut-out had taken place or taken off the accident of chain, the two ends of scraper plate just can produce differential, and are sheared destruction.Therefore, mud scraper just must be provided with protective device, and when chain rupture taking place or take off chain, its protective device should cut off electrical source of power rapidly, and is out of service, and the equipment of protecting is avoided great destruction.The protective device of original mud scraper has protection to three kinds of situations: the one, and scraper plate distortion protection; when scraper plate two ends movement velocity is inconsistent; if they have surpassed preset value by the surrounding time difference that probe detects; the monitoring system controller can send warning, cuts off motor power automatically.The 2nd, the scraper plate operation protection that gets loose, when mud scraper move, if probe detection finally scraper plate not, or forward and backward scraper plate movement space time during above preset value, the monitoring system controller can send warning, cuts off motor power automatically.The 3rd, the torque overload protection, the drive unit of every mud scraper all is furnished with a safety pin, is responsible for cutting off the tractive force of chain drive-belt when torque overload.As shown in Figure 1, its probe test point of existing mud scraper is installed in the K place of west end at the bottom of the pond.When reality is used, accident has taken place one time, chain rupture has taken place in B, C place at the bottom of the east pond, but AB section scraper plate ruuning situation we can say with chain rupture before be basic the same, this is because it still can lean on the rotation of power wheel, tightly engage a chain link at a tooth and constantly continue to move forward in an orderly manner, that is to say that the speed that the two ends of the scraper plate of AB after chain rupture still can be consistent is moving forward, scraper plate can not sheared torsional deformation.Wherein two kinds of defencive functions of protective device are that get loose protection and distortion protection of scraper plate operation all can not be played control action to the scraper plate of AB section like this; because even these scraper plates have passed through the detection of probe; can not become aware of the chain that broken in his back yet, shut down thereby take place in advance to report to the police automatically.Therefore, having seen that clearly its protective device is to have circumscribedly, is insecure, and its probe test point design is irrational.Because it cuts off motor power immediately in the time of can not or taking off the chain accident in any old place generation chain rupture out of service, just can be detected chain rupture during test point or take off the chain accident out of service but the place that will rupture by the time continues to run until probe.Mud scraper just begins to have been destroyed after the chain that broken in fact, but its protective device performs practically no function, and has no the reaction action.Thus, such protection is not prompt enough and effective.Also have, in this accident, safety pin not have to be cut off because of torque overload the tractive force of mud scraper, it seems the improvement that awaits of the poor reliability of this mechanical protection, the material selection of safety pin and the size of diameter.
The utility model content
The purpose of this utility model is to provide a kind of probe installation location reasonable, can satisfy the detection requirement that probe twists protection in earlier stage to scraper plate and takes off chain protection, at the modified mud scraper protective device of the equipment that can protect rapidly early stage of accident.
The purpose of this utility model can reach by following measure: a kind of modified mud scraper protective device; comprise power wheel, bend wheel, break-in pressure rail bar, transmission main shaft, scraper plate, chain, motor, monitoring system controller, detection probe; the both sides driving chain is moving wheels, bend wheel, formation both sides closed circuit respectively; scraper plate is loaded between the chain of both sides, it is characterized in that: detection probe is loaded on the position after a while, point of penetration A place of power wheel transferring power.
The purpose of this utility model can also reach by following measure: detection probe is loaded on the position at 0.1 meter after a while～3 meters at power wheel transferring power point of penetration A place.The installation site of detection probe is positioned on the face of pond.
The utility model has following advantage compared to existing technology:
1. the detection probe installation site is reasonable; can satisfy the detection requirement that probe twists protection in earlier stage to scraper plate and takes off the chain protection; after no matter where chain rupture has taken place or has taken off the chain accident in the place, place; when first scraper plate passes through the probe test point; can detect the scraper plate two ends at once and have speed difference and poor by the time interval; make the monitoring system controller send warning simultaneously, cut off the electricity supply, protect equipment rapidly.
2. the detection probe that was installed in originally at the bottom of the pond, be retrofitted on the face of pond position after a while, power wheel transferring power point of penetration place, make probe not need very high-grade waterproof sealing performance, and easy to maintenance.
Description of drawings
Fig. 1, Fig. 2 are the structural principle schematic diagram of existing mud scraper;
Fig. 3 is the installation site structural representation of the utility model detection probe;
Fig. 4 is the motion change view of scraper plate at the bottom of the pond after the chain rupture.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 3～Fig. 4, the utility model comprises power wheel 1, bend wheel 2,3,4, break-in pressure rail bar 5, transmission main shaft 6, scraper plate 7, chain 8, detection probe 9, motor, monitoring system controller etc.The mounting structure of whole machine is same as the prior art, and difference is the installation site of detection probe 9.The detection probe that was installed in K place at the bottom of the pond under water originally, be retrofitted in that the pond face is water-powered takes turns (see figure 3) on about after a while 3 meters position, H place, 1 point of penetration A place.Again by a side driving chain is arbitrarily chosen B at the bottom of the pond, the C place carries out the chain rupture simulated test, and the variation of damage process has taken place at once:
1. the scraper plate 7 after chain rupture C place, the speed of service is slack-off, has produced speed difference with the other end of not chain rupture, and scraper plate has been subjected to the destruction of shearing force, makes 7 beginnings of original straight scraper plate at torsional deformation at leisure with to the pendulum (see figure 4) of retreading.
Scraper plate 7 before chain rupture B place, the speed of service then basically with chain rupture before the same, scraper plate 7 still keeps straight state continuing to move forward (see figure 4).
3. on the face of pond, observe obviously that different variations has appearred in the scraper plate 7 of both sides after by power wheel 1.In a side of chain rupture, scraper plate 7 speeds of service are at once slack-off, and the sag of its driving chain 8 is becoming big gradually; And the opposite side of chain rupture not, scraper plate 7 speeds of service are still constant, simultaneously when first scraper plate 7 by the probe test point after about 15 seconds (about 10 centimeters distance of promptly having passed by), the scraper plate 7 of that side of chain is not also slowly come the position of probe test point because at this moment broken, so the monitoring system controller of that side of chain rupture does not just only allow regulation in 15 second scopes by both surrounding time differences of setting, sent the power supply that motor has also been cut off in overtime warning automatically exactly, mud scraper is just out of service at once.
Whole destructive testing is from starting to autostop greatly about 5 minutes.Through scrutiny, all parts of mud scraper all are not damaged after the shutdown.
