The utility model discloses a kind of anti-belt laterally turning-over device of band conveyor, described band conveyor comprises roller rack and is installed on the carrying roller on described roller rack, belt is positioned on described carrying roller, wherein, described anti-belt laterally turning-over device comprises limit switch and cord-like component, and described limit switch is serially connected with in the control circuit of described band conveyor; Described roller rack both sides are provided with bracing frame, support frame as described above are provided with described limit switch; Described cord-like component is positioned at above described belt, and its two ends connect with the limit switch be positioned on each support frame as described above respectively, and when described belt deviation, belt touches described cord-like component, thus triggers described limit switch action, and described control circuit is disconnected.Adopt anti-belt laterally turning-over device of the present utility model, after belt deviation, the control circuit of band conveyor can be disconnected, thus prevent belt from turning on one's side.
Description
Technical field
The utility model relates to a kind of band conveyor, particularly relates to a kind of anti-belt laterally turning-over device of band conveyor.
Background technology
In the production industries such as exploitation on ore deposit, harbour are loaded in bulk, power plant, iron and steel enterprise, usually need adopt band conveyor convey materials.Band conveyor has much organizes carrying roller, and belt is positioned on carrying roller, is configured to a hopper, in this hopper, carries material, realized the conveying of material by the movement of belt.Band conveyor can meet the needs of mass transport, but when reality uses, belt sideslip may occur and even turns on one's side, once belt is turned on one's side, material will spill, and have impact on the normal work of band conveyor.
For avoiding the generation of this situation, in prior art, disclose a kind of anti-belt laterally turning-over device.See Fig. 1, band conveyor includes roller rack 4, roller rack 4 is provided with the carrying roller 5 for back-up belt 6, this anti-belt laterally turning-over device comprises the strut bar 1 being arranged at roller rack 4 both sides, elastic rod 2 is connected with above strut bar 1, elastic rod 2 is obliquely installed relative to strut bar 1, elastic rod 2 is provided with stopper 3.Under normal circumstances, when belt generation sideslip touches this stopper 3, elastic rod 2 displacement slightly, the edge that its elastic acting force will act on belt 6 by stopper 3 afterwards makes belt 6 reset.But when belt 6 sideslip is serious, this may cause belt turnup, and it touches less than stopper, and then turns on one's side.
For the problems referred to above existing in prior art, provide a kind of anti-belt laterally turning-over device newly significant.
Utility model content
The utility model provides a kind of anti-belt laterally turning-over device of band conveyor, and it can solve the problem of belt rollover.
For achieving the above object, the anti-belt laterally turning-over device of band conveyor of the present utility model, described band conveyor comprises roller rack and is installed on the carrying roller on described roller rack, belt is positioned on described carrying roller, wherein, described anti-belt laterally turning-over device comprises limit switch and cord-like component, and described limit switch is serially connected with in the control circuit of described band conveyor; Described roller rack both sides are provided with bracing frame, support frame as described above are provided with described limit switch; Described cord-like component is positioned at above described belt, and its two ends connect with the limit switch be positioned on each support frame as described above respectively, and when described belt deviation, belt touches described cord-like component, thus triggers described limit switch action, and described control circuit is disconnected.
Preferably, described cord-like component is steel rope.
The anti-belt laterally turning-over device of band conveyor of the present utility model; by arranging cord-like component above belt; the two ends of cord-like component are all connected with the limit switch being serially connected with band conveyor control circuit; when belt deviation; cord-like component tractive limit switch; make limit switch be in the state of disconnection, thus disconnected by control circuit, band conveyor is shut down.This mode, can effectively prevent belt from turning on one's side.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-belt laterally turning-over device of band conveyor in prior art, and it is installed on band conveyor;
Fig. 2 is the structural representation of the anti-belt laterally turning-over device of band conveyor of the present utility model, and it is installed on band conveyor;
Fig. 3 is the connection diagram of limit switch in the control circuit of band conveyor in Fig. 2.
Detailed description of the invention
Below, by reference to the accompanying drawings, structure of the present utility model and principle of work etc. are further described.
See Fig. 2, band conveyor comprises roller rack 4 and is installed on the carrying roller 5 on roller rack 4, and belt 6 is positioned on this carrying roller 5, so that transported material.
Anti-belt laterally turning-over device of the present utility model, turns on one's side after preventing belt deviation, ensures the normal conveying of material.As shown in Figure 2, this anti-belt laterally turning-over device comprises bracing frame 7, limit switch 8 and cord-like component 9.
Limit switch 8 is series in the control circuit of band conveyor, and the both sides of roller rack 4 are provided with bracing frame 7, bracing frame 7 is provided with this limit switch 8.Cord-like component 9 is positioned at above belt 6, and its two ends connect with the limit switch 8 be positioned on each bracing frame 7 respectively.When sideslip does not occur belt 6, cord-like component 9 is roughly horizontal; When sideslip occurs belt 6, belt 6 touches cord-like component 9, and this cord-like component 9 pulls the contact action of limit switch 8 trigger internal, make this limit switch 8 be in off-state, and then the control circuit of band conveyor is in off-state.Cord-like component 9 can make multiple choices, such as steel rope etc.Adopt limit switch 8 to coordinate with cord-like component 9, before belt 6 is turned on one's side, band conveyor can be shut down, prevent material from spilling.
See Fig. 3, the control circuit of band conveyor is serially connected with successively fuse F, normally closed switch SB1, normal open switch SB2, the normally closed contact FT of thermal relay, two limit switches 8 and contactless switch M, normal open switch SB2 is parallel with the open contact of contactless switch M.As shown in FIG., limit switch 8 is normally closed switch, and it is series in this control circuit, thus the shutdown participating in band conveyor controls, and prevents belt 6 from turning on one's side.
Composition graphs 2, Fig. 3; when belt 6 by side upwards sideslip time; promotion cord-like component 9 moves up by it; cord-like component 9 pulls the limit switch 8 on left side and right side; limit switch 8 is made to turn to off-state by closure state; and then causing the control circuit of band conveyor to disconnect, band conveyor is shut down.
In addition; can also by the Anti-side-turning device mentioned in prior art and this Anti-side-turning device of the present utility model with the use of; in the both sides of roller rack 4, strut bar 1 is still set; elastic rod 2 is set above strut bar 1; elastic rod 2 is arranged stopper 3; can lead to stopper 3 when slight sideslip occurs belt 6 makes it reset, and shuts down without the need to band conveyor.This mode, can play duplicate protection.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that on the basis of not departing from principle of work of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
