Abstract
The invention discloses a device for online and real-time detection of tensile force of a template suspension rope in building a well wall, which belongs to detection devices for mine construction. The device consists of a weighting sensor arranged bellow a head sheave bearing block on a head sheave beam, an A/D conversion circuit connected with the weighting sensor, a programmable logic controller (PLC) connected with the A/D conversion circuit, an industrial personal computer (IPC) connected with the programmable logic controller (PLC), and an alarm connected with the industrial personal computer (IPC). The weighting sensor acquires pressure signals, and the pressure signals are converted into digital signals through the A/D conversion circuit and are sent to the industrial personal computer for displaying the tensile force of the template suspension rope after the operation processing by the programmable logic controller (PLC); and when the tensile force exceeds the rated tensile force value of a steel wire rope, the industrial personal computer outputs an alarm signal, so that the alarm gives an alarm, cuts off a power supply, and automatically records the overcharge times. The device has the advantages of measuring out the tensile force change condition of the steel wire rope in an online and real time mode under the condition of not influencing the promotion of the normal working of a system so as to achieve the aim of protecting the steel wire rope.
Description
Technical field
The present invention relates to a kind of checkout equipment of shaft building industry, online in real time detects the equipment of tensile force of template suspension rope when specifically being a kind of building well wall.Be mainly used in the ore deposit and build the online in real time detection of tensile force of template suspension rope in the building well wall construction.
Background technology
The ore deposit is built in the construction, and template suspension rope and borehole wall close together generally have only about 50mm, when building well wall, needs to put forward or transfer template.In lifting process, particularly start moment, the bump probability of friction of the template and the borehole wall is big especially, thereby makes the stressed increase of template suspension rope, even several times increase, and brings potential safety hazard.Nearly all this situation can occur in each construction place, also can cause the template suspension fracture of rope sometimes, fall, cause down-hole workmen's fatal accident in the down-hole.
Existing testing device for wire ropes can detect steel wire rope tension, and when still measuring specially under the situation of slow running, then can not carry out lifting work this moment, promptly can not wire rope be detected online in real time.
Summary of the invention
For solving the problems of the technologies described above, online in real time detects the equipment of tensile force of template suspension rope when the invention provides a kind of building well wall.Under the situation of not destroying elevator system; enable to measure the lineoutofservice signal pull situation of change; for operating personnel provide reliable wire rope strained detection device, can when lineoutofservice signal pull reaches design load, cut off the power supply to power-equipment automatically simultaneously, thereby reach the purpose of protecting wire rope.
The present invention realizes with following technical scheme: online in real time detects the equipment of tensile force of template suspension rope during a kind of building well wall, comprising:
Be installed in some LOAD CELLS that the sky on the head sheave beam is used to gather the downward pressure of bearing seat below the wheel bearing seat;
Be connected with LOAD CELLS, the pressure simulation conversion of signals of gathering become the several A/D change-over circuit of digital signal;
Be connected with the A/D change-over circuit, be used for signal amplification, internally stored program, the Programmable Logic Controller PLC of actuating logic computing;
PLC is connected with Programmable Logic Controller, is used to finish the industrial computer IPC of storage, demonstration and the execution function of data;
IPC is connected with industrial computer, the alarm of reporting to the police when surpassing design load.
The LOAD CELLS of below head sheave beam top chock, installing, record the downward pressure of bearing seat, convert digital signal to by the A/D change-over circuit, PLC amplifies signal through Programmable Logic Controller, calculation process is sent industrial computer indicating template suspension rope pulling force after comparing with setting value; When exceeding the rated pull of rope value, industrial computer output alarm signal alarm sends reports to the police and cuts off the electricity supply, and writes down the number of times of overload automatically.Provide a breakpoint by the industrial computer interface, be linked in the motor control loop, finish the wire rope protective effect, remind the maintainer to add thorough examination wire rope dynamics simultaneously.
The invention has the beneficial effects as follows: under the situation that does not influence the elevator system operate as normal; can online in real time measure the lineoutofservice signal pull situation of change; for operating personnel provide reliable wire rope stressing conditions; can when lineoutofservice signal pull reaches design load, cut off the power supply to power-equipment automatically simultaneously, thereby reach the purpose of protecting wire rope.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is the present invention's electricity theory diagram.
Embodiment
As shown in drawings, the equipment that online in real time detects tensile force of template suspension rope during a kind of building well wall below the sky wheel bearing seat that is installed on the head sheave beam, be used to gather the downward pressure of bearing seat some LOAD CELLS, be connected with LOAD CELLS, with the pressure simulation conversion of signals of gathering become digital signal several A/D change-over circuit, be connected with the A/D change-over circuit, be used for signal amplification, internally stored program, the Programmable Logic Controller PLC of actuating logic computing; PLC is connected with Programmable Logic Controller, is used to finish the industrial computer IPC of storage, demonstration and the execution function of data; IPC is connected with industrial computer, and the alarm of reporting to the police when surpassing design load is formed.
In the present embodiment, below every template suspension rope sky wheel bearing seat, LOAD CELLS is installed all,, two LOAD CELLS is installed below each bearing seat for improving the accuracy of acquired signal.Each LOAD CELLS all connects an A/D change-over circuit.In Programmable Logic Controller PLC, store the program that calculates pull of steel wire according to the cornerite of wire rope and head sheave.The display of industrial computer adopts liquid crystal display.
The force value of LOAD CELLS by recording, output 4-20mA normalized current signal converts digital signal to by the A/D change-over circuit, carries out signal through Programmable Logic Controller PLC again and amplifies, handles, convert 0-10kHz output to, convert digital quantity to through the PLC high speed output.Compare with set-point, when the rated pull of rope value that exceeds setting 50% the time, the industrial computer output signal drives alarm equipment alarm, exceeds promptly to send more than 50% to report to the police and cut off the electricity supply, and the number of times of record overload automatically.Provide a breakpoint by the industrial computer interface, be linked in the motor control loop, finish the wire rope protective effect, remind the maintainer to add thorough examination wire rope dynamics simultaneously.
