Including dynamic track weighing sensor, a signal processo, central controller, show and the warning system, developments track weighing sensor is foil gage weighing sensor, wholly be profile modeling track form, through falling original track absolutely the mode fixed mounting that splices after the small matter in original track on the track that gets into the shaft cage, developments track weighing sensor's signal output is connected to signal processor, signal processor's signal output is connected to central controller, central controller is connected with demonstration and warning system. The utility model discloses a measuring of weighing of not stopping does not influence normal promotion operation, weighing sensor has that strong, the anti deformability of rigidity is strong, light in weight, the easy advantage maintained of on -the -spot installation. The appearance of the overweight condition can effectively be avoided promoting by this device, guarantees to promote safety.
Description
Technical field
The utility model relates to prior-warning device of weighing, and specifically a kind of vertical shaft for mine based on dynamic railway truck scale technology promotes overload protective device.
Background technology
At present, most of mine all adopts vertical shaft cage improving material and upper and lower personnel, and therefore promoting safety is the importance being related to whole mine safety.The existence promoting overload condition becomes the major hidden danger threatening and promote safety, but each bargh does not also stop the efficient apparatus of overload hidden danger at present.
Utility model content
The utility model is intended to solve its problem of above-mentioned shaft hoisting overload early warning, and provide a kind of vertical shaft for mine based on dynamic railway truck scale technology to promote overload protective device, cage advance Mobile state weighing measurement is entered at mine car, detect its load capacity, then do not report to the police only show its weight as do not exceeded alarm setting value; Once after institute's survey mine car load capacity exceedes alarm setting value, send sound and light alarm signal, remind relevant staff to note, effectively prevention vertical shaft for mine promotes the generation of overload condition, ensures mine hoisting safety.
The technical scheme that the utility model solves the employing of its technical matters is:
A kind of vertical shaft for mine promotes overload protective device, comprise dynamic track LOAD CELLS, signal processor, system controller, display and alarm system, dynamic track LOAD CELLS is strain-gauge LOAD CELLS, overall in profile modeling rail shape, be fixedly mounted on by the mode of splicing in original track after a trifle that original track is broken and enter on the track of vertical shaft cage, the signal of dynamic track LOAD CELLS exports and is connected to signal processor, the signal of signal processor exports and is connected to system controller, and system controller is connected with display and alarm system.
Dynamic track LOAD CELLS, the detection of weighing before entering cage for mine car, and surveyed data are transferred to signal processor;
Data that LOAD CELLS is surveyed are carried out amplification and are processed and be transferred to system controller by signal processor;
System controller, whether the data transmitted by signal processor carry out process computing, overweightly to judge;
Display and alarm system, export data by controller and show in real time, carry out audible and visual alarm for overweight by alarm device, and prompting relevant staff note.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
Adopt Dynamic Weighing Technology, realize not stopping detection of weighing, do not affect normal hoisting operation; Profile modeling rail formula LOAD CELLS, have that rigidity is strong, non-deformability is strong, lightweight, the advantage that is easy to on-site installation and maintenance, and strain-gauge LOAD CELLS mature and reliable precision is high, makes this device effectively can avoid promoting the appearance of overweight condition, ensure to promote safety.
As preferably, the utility model technical scheme is further:
Signal processor, system controller and display and alarm system are placed in the casing of a Flameproof and intrinsically safe structure, and described casing is installed in each horizontal promotion signal control cabin of auxiliary shaft.
Signal processor is LDST-I (V)-ST, carries out the output signal of LOAD CELLS to isolate the master die analog quantity signal being converted to system controller and can identifying.
System controller take Siemens S7-200PLC as core processing device, and the analog signals passed back by signal processor carries out process computing, carries out judgement output to whether alleged object is overweight.
System controller is connected with host computer by communication, makes this device realize carrying out the functions such as file statistics, alarm inquiry, data query to the data collected.

Signal processor 2 is LDST-I (V)-ST, carries out the output signal of dynamic track LOAD CELLS 1 to isolate the master die analog quantity signal being converted to system controller 3 and can identifying.
System controller 3 take Siemens S7-200PLC as core processing device, and the analog signals passed back by signal processor 2 carries out process computing, carries out judgement output to whether alleged object is overweight.
Host computer 5, by communication, carries out file statistics, alarm inquiry, data query to the data that system controller 3 collects.
System controller 3 is exported data and shows in real time by display and alarm system 4, carries out audible and visual alarm for overweight by alarm device, and prompting relevant staff note.
Above-described embodiment is only to the utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
