Description
Technical field
The utility model belongs to belt-conveying technical field, is specifically related to the anti-skidding automatic detection protection device of a kind of belt.
Background technology
Industrial belt conveyer is also known as belt conveyer, consequence and effect is taken in the conveying industries such as power plant are produced, band conveyor is the machinery of a kind of friction-driven transported material in a continuous manner, and its reliable smooth running has great significance to guarantee enterprise security, High-efficient Production.Slipping of the belt sideslip is the common phenomenon that belt feeder runs; due to the sideslip measurement mechanism that do not skid; if belt does not run and causes slipping of the belt when motor rotation; or the serious sideslip of belt in operational process; not only easily cause material spilling, belt tearing can be made time serious to break, even cause stopping accident; belt is installed after scrapping again need drop into a large amount of manpower and materials, causes great economic loss.So avoid slipping of the belt sideslip to be a great problem that belt feeder runs.
Summary of the invention
The utility model be intended to solve produce in belt transporter operational process in prior art slipping of the belt, break and technical matters that serious sideslip cannot detect in time and protect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Design the anti-skidding automatic detection protection device of a kind of belt, comprise belt run signal detector switch a, close to master cock 1, relay K 1, K2, and time relay 2,3, connect with described belt run signal detector switch a after described time relay 2,3 is in parallel, connect close to master cock 1 with described after described relay K 1 is in parallel with described time relay 2; The normally closed contact b of described relay K 1 connects with described time relay 3; Described time relay 2,3 often to open delayed contact c, d in parallel with the contact e of relay K 2; The normally closed contact g of described relay K 2 is linked in the electric control loop of belt transporter, is formed and goes electric interlocking to control.
Preferably, also comprise warning indicator lamp 4 and ann reset button 5, the open contact f of described relay K 2 connects with warning indicator lamp 5, described time relay 2,3 often open delayed contact c, d in parallel with the contact e of relay K 2 after be in series with described ann reset button 5.
Wherein, when described time relay 2 anomalous behavior, it is often opened delayed contact c and closes, and described relay K 2 powers on, and the contact e of described relay k2 closes, and forms self-locking with the closed delayed contact c that often opens.
The beneficial effects of the utility model are:
1. can realize real-time detection and the protection of the abnormal condition such as belt transporter skids in operational process, sideslip; can power themselves down when operation exception appears in belt; avoid belt to be in operation breaking or skid the belt accident caused; effectively extend the service life of equipment, decrease the loss because disorderly closedown causes.
2. warning indicator being set, owing to forming self-locking state during relay K 2 action, will continuing to report to the police when artificially not removing alarm condition, be convenient to intuitive judgment fault, ann reset button is set, can to reset relevant switch, contact by a key, safeguard simple and convenient, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the control principle drawing of the anti-skidding automatic detection protection device of the utility model belt;
A is belt run signal detector switch; 1 is close to master cock; K1, K2 are relay; 2,3 is time relay; B is the normally closed contact of relay K 1; C, d be time relay 2,3 often open delayed contact; E is the contact of relay K 2; G is the normally closed contact of relay K 2; 4 is warning indicator lamp; 5 is ann reset button, and f is the open contact of relay K 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described, but the following example is only used to describe embodiment of the present utility model in detail, and limits scope of the present utility model never in any form.
Embodiment 1: the anti-skidding automatic detection protection device of a kind of belt, see Fig. 1, comprise belt run signal detector switch a, close to master cock 1, relay K 1, K2, and time relay 2,3, also comprise warning indicator lamp 4 and ann reset button 5, connect with belt run signal detector switch a after time relay 2,3 is in parallel, connect with close to master cock 1 after relay K 1 is in parallel with time relay 2; The normally closed contact b of relay K 1 connects with time relay 3; Time relay 2,3 often to open delayed contact c, d in parallel with the contact e of relay K 2; The normally closed contact g of relay K 2 is linked in the electric control loop of belt transporter, is formed and goes electric interlocking to control.The open contact f of relay K 2 connects with warning indicator lamp 5, time relay 2,3 often open delayed contact c, d in parallel with the contact e of relay K 2 after be in series with ann reset button 5.
Wherein, when time relay 2 anomalous behavior, it is often opened delayed contact c and closes, and relay K 2 powers on, and the contact e of relay k2 closes, and forms self-locking with the closed delayed contact c that often opens.
The specific works mode of the anti-skidding automatic detection protection device of the utility model belt is: after belt transporter startup optimization; belt pulley rotates at the effect bottom roller of belt; the induction metal plate cycle rotates; the electric control loop energising of belt transporter; charged close to master cock 1 cycle; relay K 1 is connected along with the connection close to master cock 1; disconnect along with the disconnection close to master cock 1; the normally closed spot control time relay 3 of the K1 open contact period relay 2, K1 of relay.Time relay 2,3 often open delayed contact c, d control relay K2, the normally closed contact g of relay K 2 accesses in the electric control loop of belt transporter, and the open contact f of relay K 2 connects warning indicator lamp 4.When belt transporter normally runs, this device normally detects, and K2 is in hold mode, maintains belt and normally runs.The time delay of time relay can be set as 3 seconds and 20 seconds respectively, when sheetmetal does not have by during close to master cock 1 in setting-up time, namely skidding or abnormal condition occur appears in belt, time relay 2 and relevant contacts meeting action thereof, warning indicator lamp glimmers, the normally closed contact g of relay K 2 disconnects, the normally closed contact of relay K 1 disconnects, and time relay 3 is connected it and often opened delayed contact, motor dead electricity, belt is out of service, when after trouble-shooting, push for emergency reset button, and all contacts reset, power on, equipment continues normal operation.
Current belt transporter does not have the function detecting the abnormal condition such as belt deviation or skidding in real time usually, when appearing at motor rotation sometimes, and belt does not run, so there is situation about being broken by belt, great economic loss is caused to enterprise, the belt of hundreds of rice is scrapped, and has dropped into a large amount of man power and materials when again installing belt.Use the anti-skidding automatic detection protection device of the utility model belt; when occurring that skidding or the serious sideslip of belt cause belt to rotate; can cut off the operation of motor the very first time, thus actv. protection belt is not destroyed or damage, guarantees the safe operation of belt.The utility model structure is simple, only need access in the electric control loop of transport plane and can use, can be widely used in belt-conveying industry, increases the safety of belt-conveying, reduces use cost.
In conjunction with the accompanying drawings and embodiments embodiment of the present utility model is elaborated above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also carry out changing or changing under the prerequisite not departing from the utility model aim.
