Description
Technical field
The utility model belongs to belt feeder, particularly relates to a kind of warning protecting device of belt feeder counterweight tower.
Background technology
Belt feeder is the abbreviation of belt conveyer, has fixed type and movable type, and structure is simple, and efficiency is high.The continuous conveyor of material carrying and driving component is made with flexible load-transfer device.Article one, load-transfer device is for no reason around head roll and bend pulley.Upper inferior division between two cylinders is respectively with some idler stands.Material is placed in top set, utilizes the friction force traction load-transfer device between head roll and band and material to run.At present, specialized bulk goods reclaiming technology many employings large-scale conveyor conveying articles of harbour, realizes goods and loads and transports the operation of going on board from stockyard.Large-scale conveyor comprises belt conveyor, truss, motor, counterweight tower and cylinder.When conveyer starts, counterweight tower dolly moves forward and backward, in order to adjust the degree of tightness of belt conveyor along with the stretching of belt conveyor.When belt conveyor rupture, counterweight protector steel rope have the fault such as groove or fracture time, counterweight tower dolly will produce certain improper displacement.Now, if parking can cause belt tearing and more serious breakdown of equipment not in time.
Number of patent application: 201110349391.4 disclose a kind of fault detection device for belt conveyer, form primarily of industrial computer, support, displacement pickup, support straddles in belt conveyer frame, support is interval with multiple displacement pickups of vertical, horizontal arrangement, the curved shape of multiple displacement pickup symmetric offset spread of longitudinal arrangement, transversely arranged multiple displacement pickups, in horizontally, lean bottom load-transfer device; Each displacement pickup is connected with industrial computer by communication cable.Utilize and multiple fault detection device for belt conveyer is set at load-transfer device bottom interval, multiple displacement pickups of longitudinal and transverse arrangement on multiple fault detection device for belt conveyer are made to lean the bottom at load-transfer device, each displacement pickup is connected with industrial computer by communication cable, can comprehensive detection belt conveyer overload, skidding, sideslip, longitudinal tear, horizontal broken belt various faults.Above-mentioned patented technology is more impetuous comparatively large to main equipment repacking, must stop production and just can complete during enforcement.
Utility model content
The utility model is to overcome deficiency of the prior art, provides a kind of warning protecting device of belt feeder counterweight tower, can monitor, to ensure the safety precaution to belt feeder when belt starts to the little truck position of counterweight tower.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of warning protecting device of belt feeder counterweight tower, comprise counterweight tower dolly, article two, parallel truss and counterweight tower body, it is characterized in that: the counterweight tower dolly pulley bracket center of described counterweight tower body is provided with a displacement monitoring hole, run through in described displacement monitoring hole and have steel rope, described steel rope one end and truss are fixed, the steel rope other end is connected with detectability bit switch, described detectability bit switch is fixed on opposite side truss, form the counterweight tower dolly improper displacement alerting signal mechanism of equilateral triangle, described detectability bit switch access PLC system alarm detection point.
The safety monitoring stroke range of described counterweight tower dolly improper displacement alerting signal mechanism is 10-15cm.
Described counterweight tower dolly pulley bracket center arranges floating type draw ring, runs through steel rope in described draw ring.
Beneficial effect: the displacement of counterweight tower dolly when the belt that the utility model belt feeder counterweight tower warning protecting device can monitor large-scale conveyor completely starts, and ensure safety precaution when belt starts, stop in time and avoid belt tearing and more serious breakdown of equipment to occur.The alarm and protection of harbour bulk goods operation belt feeder has promotional value.

Detailed description of the invention
Below in conjunction with preferred embodiment, to the detailed description of the invention provided according to the utility model, details are as follows:
Embodiment
Refer to accompanying drawing, compared with prior art, the utility model provides a kind of warning protecting device of belt feeder counterweight tower, comprise counterweight tower dolly 1, article two, parallel truss 2 and counterweight tower body (not shown), the counterweight tower dolly pulley bracket center of described counterweight tower body is provided with a displacement monitoring hole 3, run through in described displacement monitoring hole and have steel rope 4, described steel rope one end and truss are fixed, the steel rope other end is connected with detectability bit switch 5, described detectability bit switch is fixed on opposite side truss, form the counterweight tower dolly improper displacement alerting signal mechanism of equilateral triangle, described detectability bit switch access PLC system alarm detection point.The safety monitoring stroke range of described counterweight tower dolly improper displacement alerting signal mechanism is 10-15cm.When the belt of large-scale conveyor starts, pulley bracket position should within detection range, if exceed detection range, monitoring site moves past greatly, and steel rope zip drives travel switch action, and touch PLC system alarm detection point and report to the police, belt feeder emergent stopping operates.
Preferred version of the present utility model is: described counterweight tower dolly pulley bracket center arranges floating type draw ring 6, runs through steel rope, avoid steel rope abrasion in described draw ring.
Install and working process
1, measure
When large-scale conveyor belt starts, counterweight tower counterweight protector upwards can lift due to the tension force of apron drawing, and dolly can be advanced forward by belt drive to belt simultaneously.First select check point to be dolly pulley bracket center-point, start belt and measure now, the stroke range during distance quiescence of counterweight tower dolly monitoring point is 10-15cm, and the present embodiment selects 15cm as the limit of displacement detecting point.Ensure that steel rope zip is safety distance within dolly moves forward 15cm, touch limit switch after going beyond the scope and report to the police.
2, integral manufacturing is installed
First make the draw ring of check point, by steel rope zip through draw ring, be fixedly expert on frame in one end.Travel switch installed by the row frame of its parallel position, the other end of steel rope zip is fixed on the action pull bar of travel switch.
3, electrical equipment control access
Refer to accompanying drawing 2, lay the circuit to belt local control box control point from travel switch, accessed by wiring wire size 0005-1,0197-1 by the normally closed point of travel switch on the access terminal 39,5 of the module of PLC control system, counterweight tower dolly tensioner limiting node 1-2 connects with belt tension limiting node 11-12.So far whole warning protecting device installation.
Through in-place test, the utility model belt feeder can be monitored completely the displacement of counterweight tower dolly when belt starts with the counterweight tower of warning protecting device, and safety precaution when ensureing that belt starts.
Above-mentioned detailed description of carrying out with reference to the warning protecting device of embodiment to this kind of belt feeder counterweight tower; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
