The utility model is used for protecting the link plates and the chain links of the plate feeder, can realize tripping protection, not only can protect the link plates and the chain links of the plate feeder from being damaged by pulling and getting broken by pulling, but also can prevent equipment from tripping due to false operation.
Description
Technical field
The utility model relates to the safe operation of conveyer, especially relates to the carrier bar chain link fender guard of plate belt feeder.
Background technology
Plate belt feeder is the visual plant that material transmits; it comprises actuating device electrical motor and the board-like chain plate of executive device chain link; exist very big rotating speed no-load voltage ratio between actuating device and the executive device; make executive device when load changes; reaction not quite makes protection sensitive inadequately on actuating device.Prior art only from the angle design fender guard of protection electrical motor, reductor, can't effectively be protected the carrier bar chain link, and the carrier bar chain link of plate belt feeder can rupture when the load that bears above designed capacity.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art; a kind of carrier bar chain link fender guard simple in structure, practical, plate belt feeder easily is provided; can protect board-like chain plate chain link not pulled, break, can prevent that again equipment malfunction from tripping.
To achieve these goals, the technical solution of the utility model is as follows:
The carrier bar chain link fender guard of plate belt feeder is characterized in that it comprises that current signal detects the loop, the protection control loop, described current signal detects the loop current transducer is installed, the protection control loop comprises omnipotent digital display meter, time relay, intermediate relay and motor contactless switch; The current transducer measured signal is delivered to the omnipotent digital display meter of protection control loop, and omnipotent digital display meter connects time relay through alarm actuating contact, and time relay connects intermediate relay through the time relay contact, and intermediate relay connects the motor contactless switch through the intermediate relay contact.
Described current signal detects the loop can be connected to amperemeter/ammtr.
The utility model is to increase by a cage plate machine load-measuring device on existing equipment; by current sampling, and by field experience setting digital display meter alarming value, the time-delay that alerting signal is set by field experience; at last signal is received the electrical equipment trip(ping) circuit, thus the preventive device safe operation.
The plate belt feeder carrier bar chain link fender guard that the utility model provides is used for the carrier bar chain ring protection of plate belt feeder, and it can realize the protection tripping operation, can protect board-like chain plate chain link not pulled, break, and can prevent that again equipment malfunction from tripping.
A kind of plate belt feeder carrier bar chain link fender guard that the utility model provides uses proof by reality, has reached predetermined purpose, is applicable to the carrier bar chain ring protection of various plate belt feeders.
Description of drawings.
Fig. 1 detects the loop scheme drawing for current signal;
Fig. 2 is a structural representation of the present utility model;
Among the above figure: the 1-current transducer; The omnipotent digital display meter of 2-; The omnipotent digital display meter output point of 3-alarm actuating contact; The 4-time relay; 5-time relay contact; The 6-intermediate relay, 7-intermediate relay contact, 8-motor contactless switch, 9-amperemeter/ammtr.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment:
Fig. 1 can connect amperemeter/ammtr 9 for current signal detects the loop on the loop, and current transducer 1 has 220 volts of external powers to be its power supply; Fig. 2 has illustrated the utility model structure, plate belt feeder carrier bar chain link fender guard, it is characterized in that it comprises that current signal detects the loop, the protection control loop, described current signal detects the loop current transducer 1 is installed, the protection control loop comprises omnipotent digital display meter 2, time relay 4, intermediate relay 6 and motor contactless switch 8; Current transducer 1 measured signal is delivered to the omnipotent digital display meter 2 of protection control loop; omnipotent digital display meter 2 connects time relay 4 through alarm actuating contact 3; time relay 4 connects intermediate relay 6 through time relay contact 5, and intermediate relay 6 connects motor contactless switch 8 through intermediate relay contact 7.
By current transducer 1 the 4-20mA signal is sent in the change of plate belt feeder current of electric; flow to general-purpose digital display meter 2; the 4-20mA signal is in general-purpose digital display meter 2 process logic determines; when numerical value surpasses the data setting that presets; 3 actions of omnipotent digital display meter 2 output point alarm actuating contacts; run up time, relay 4; exist if report to the police always, reach the time setting value of presetting, 5 actions of time relay contact; start intermediate relay 6; intermediate relay contact 7 disconnects immediately, the outage of motor contactless switch 8 coils electricity, and motor quits work; plate belt feeder is shut down, and prevents that board-like chain plate chain link from breaking.
The ZGB2000*12000 heavy-duty plate rock feeder of ore dressing plant, Wengfu Group Co., Ltd. Xinlong dam crushing section; its dragging motor is the three-phase asynchronous electric of 55kw; rated current 102A; under the normal circumstances; running current is about 57A; when fluctuation takes place in the maximum back loading of rotational speed setup; maximum current can reach 95A; so the motor protecter setting value is 95A, can actv. the protection reductor be not damaged, when mine-supplying quantity little; when having big lump ore that the plate machine is blocked; current of electric has only about 75A, just plate chain plate chain link may be drawn distortion or breaks, and the safe operation of plate belt feeder has been caused serious threat.
After using the anti-breaking device of the utility model plate chain plate chain link; when Ka Kuang or stifled ore deposit incident take place; not only can in time protect and shut down tripping operation; can misoperation not shut down because of the fluctuation of load yet; prevented that effectively plate chain plate chain link is pulled out of shape; ensured the safe operation of main equipment, great contribution has been made in production.
