Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, for measuring the related motion parameters of winding and unwinding of the steel wire rope, an incremental rotary encoder can be installed on a winding drum shaft, two proximity switches are installed on a guide wheel and used for measuring and limiting the captive distance of a single-layer steel wire rope, a pulse signal output by the proximity switches is converted into the time for the guide wheel to rotate so as to judge the rising/falling state of the steel wire rope and measure the visited speed of the steel wire rope, wherein the incremental rotary encoder has the following principle: the pulse signals output by the incremental rotary encoder are converted into the rotating angle of the drum shaft to measure the winding and unwinding length of the single-layer steel wire rope, for example, the displacement of the drum shaft is converted into periodic electric signals, and then the electric signals are converted into counting pulses, so that the size of the displacement or the position of the movement is represented by the number of the pulses. However, the method of installing an incremental rotary encoder on the spool shaft is difficult to accurately measure the winding and unwinding lengths of the multi-layer wire rope, and the method of installing two proximity switches on the guide wheel bracket cannot accurately measure the winding and unwinding lengths of the multi-layer wire rope due to the relative sliding between the guide wheel and the wire rope. On the basis, the invention provides a method for calculating the winding parameters of the steel wire rope and winding machine equipment, which can better measure the winding parameters of the multi-layer steel wire rope.
To facilitate understanding of the embodiment, first, a detailed description is given of a method for calculating hoisting parameters of a steel wire rope disclosed in the embodiment of the present invention, where the method is applied to a hoisting machine apparatus, the hoisting machine apparatus is provided with a drum shaft and a guide wheel, multiple layers of steel wire ropes are wound on the drum shaft, the steel wire ropes are used for lifting and lowering a target object through the guide wheel, an absolute angle measuring device is arranged on the drum shaft, and a timing device is arranged on the guide wheel, as shown in a schematic flow chart of the method for calculating hoisting parameters of a steel wire rope shown in fig. 1, the method mainly includes the following steps S102 to S106:
in step S102, the rotation angle of the reel shaft is determined by an absolute angle measuring device. The absolute angle measuring device can represent the rotation angle of the reel shaft in a binary coding mode, and the rotation angle of the reel shaft can exceed 360 degrees. In an alternative embodiment, the mechanical position of the reel shaft is measured by an absolute angle measuring device and the measured mechanical position is converted into a binary code, so that the rotation angle of the reel shaft is determined on the basis of the binary code.
And step S104, determining the winding and unwinding time of the steel wire rope based on the relative position between the target object and the guide wheel through a timing device. The timing device is used for measuring the winding and unwinding time of the steel wire rope, in one implementation mode, the timing device can comprise a proximity switch and a wheel disc, the proximity switch is used for outputting a high level when a target object approaches to a guide wheel, outputting a low level when the target object is far away from the guide wheel, the wheel disc can start to output pulses when the proximity switch outputs the high level, the pulses are stopped to be output when the proximity switch outputs the low level, and the winding and unwinding time of the steel wire rope can be known by counting the pulse number of the pulses output by the wheel disc.
And step S106, calculating the winding parameters of the steel wire rope based on the rotation angle and the winding and unwinding duration. The winding parameters comprise winding depth and/or winding speed, the winding depth can be understood as the radius distance between the steel wire rope and the center of the winding drum shaft, and the winding speed can be understood as the speed of the winding drum shaft for winding and unwinding the steel wire rope. In some embodiments, the winding and unwinding length of the wire rope may be pre-configured, so that the winding speed of the wire rope may be calculated based on the transceiving length and the winding and unwinding time, and the winding depth of the wire rope may also be calculated based on the winding and unwinding length and the rotation angle.
The method for calculating the hoisting parameters of the steel wire rope provided by the embodiment of the invention can realize measurement of the hoisting parameters such as the hoisting depth and the hoisting speed of the multilayer steel wire rope by combining the absolute angle measuring device and the timing device, and the measured hoisting parameters have higher accuracy.
To facilitate understanding, embodiments of the present invention provide a hoist apparatus in which an absolute angle measuring device includes an absolute rotary encoder and a timing device includes a proximity switch and a code wheel. The absolute encoder has a plurality of scribe lines, each scribe line is programmed with 2 lines, 4 lines, 8 lines, 16 lines … …, so that (n-1) can be obtained 2 Where n is the number of scribe lines and the 2 is determined by the mechanical position. In addition, the proximity switch is a novel switch element which is used in an industrial automation control system to realize detection, control and full-scale contactless with an output link, and when the proximity switch is close to a target object, the proximity switch sends out a high level or a rising edge, and when the proximity switch is far away from the object, the proximity switch sends out a low level or a falling edge.
In consideration of the fact that the winding parameter calculation method of the steel wire rope provided by the embodiment of the invention needs to calculate the winding parameter of the multilayer steel wire rope, namely the rotation angle of the winding drum shaft is possibly more than 360 degrees when the steel wire rope is wound and unwound, and because the absolute encoder has a measuring range (generally 360 degrees), the absolute angle measurer comprises a multi-turn absolute rotary encoder, so that the rotation angle of the winding drum shaft can be still normally acquired when the rotation angle exceeds 360 degrees.
In an embodiment, referring to a structural schematic diagram of a winch apparatus shown in fig. 2, fig. 2 illustrates a multi-turn absolute type rotary encoder 1, a spool shaft 2, a steel wire rope 3, a guide wheel 4, a guide wheel support 5, a proximity switch 6 and a code wheel 7, wherein the spool shaft 2 is wound with a plurality of layers of steel wire ropes 3, the steel wire ropes 3 lift a target object through the guide wheel 4, the spool shaft 2 is provided with the multi-turn absolute type rotary encoder 1, the proximity switch 6 is arranged on the guide wheel support 5, the code wheel 7 is arranged on the guide wheel 4, and the number of the proximity switches is one. In addition, a rotation angle Δ Φ, a retraction length Δ L, a retraction time period Δ t, and a winding speed v are also labeled in fig. 2, and optionally, the unit of the rotation angle is "°", the unit of the retraction length is "mm", the unit of the retraction time is "s", and the unit of the winding speed is "mm/s". Further, referring to a schematic structural view of another winch apparatus shown in fig. 3, fig. 3 illustrates a spool shaft 2 on which a multi-layer wire rope 3 is wound, the spool shaft 2 being provided with a multi-turn absolute type rotary encoder 1, and exemplary hoisting depths R1, R2, R3, and R4 are indicated.
On the basis of fig. 2, the embodiment of the present invention provides an implementation manner for determining the rotation angle of the spool shaft by using an absolute angle measuring device, which can receive the position code sent by the absolute rotary encoder and convert the position code into the rotation angle of the spool shaft. As shown in fig. 2, a multi-turn absolute type rotary encoder 1 is mounted on the spool shaft 2, and the mechanical position code output from the multi-turn absolute type rotary encoder 1 is converted into a rotation angle Δ Φ of the spool shaft 2.
With continued reference to fig. 2, an embodiment of the present invention further provides an implementation manner for determining the winding and unwinding duration of the steel wire rope based on the relative position between the target object and the guide wheel through a timing device, which is shown in the following steps 1 to 3:
and 1, outputting a high level or a low level through a proximity switch based on the relative position between the target object and the guide wheel. In one embodiment, (1) if the distance between the target object and the guide wheel is less than a preset threshold, outputting a high level through the proximity switch; (2) and if the distance between the target object and the guide wheel is larger than a preset threshold value, outputting a low level through the proximity switch. For example, assuming that the preset threshold is 10mm, when the distance between the target object and the guide wheel is less than 10mm, the proximity switch sends out a high level or a rising edge, and when the distance between the target object and the guide wheel is greater than 10mm, the proximity switch sends out a low level or a falling edge.
And 2, starting to output pulses when the proximity switch outputs a high level through the code disc until the proximity switch stops outputting pulses when the proximity switch outputs a low level. In one embodiment, the code wheel begins outputting a pulse (such as a unit pulse) when the proximity switch asserts a high level or rising edge, and stops outputting a pulse when the proximity switch asserts a low level or falling edge.
And 3, counting the pulse number of the coded disc output pulse, and calculating the winding and unwinding time of the multilayer steel wire rope based on the pulse number. For example, in the time interval from the high level of the proximity switch to the low level, the coded disc outputs 5 unit pulses, and the winding and unwinding time Δ t of the steel wire rope can be directly determined to be 5 s.
In an embodiment, the hoisting parameters include a hoisting speed and a hoisting depth, for easy understanding, embodiments of the present invention provide an implementation for calculating the hoisting speed and the hoisting depth, respectively, see the following first and second ways, where the first way is used for calculating the hoisting speed, and the second way is used for calculating the hoisting depth:
the first method is as follows: if the winding parameter includes a winding speed, the winding speed of the wire rope can be calculated based on the preset winding and unwinding length and the winding and unwinding duration of the wire rope. In practical application, because the position close to the guide wheel bracket is fixed, the winding and unwinding length Δ L of the steel wire rope can be preset, and the winding speed of the steel wire rope is calculated based on the winding and unwinding length Δ L and the winding and unwinding time Δ t, wherein the relative sliding distance between the steel wire rope 3 and the guide wheel 4 can be ignored, and then the winding speed v of the steel wire rope 3 is equal to Δ L/Δ t.
The first method is as follows: if the hoisting parameter includes the hoisting depth, the step of calculating the hoisting parameter of the steel wire rope based on the rotation angle and the winding and unwinding time length can be executed according to the following method shown in the steps a to c:
and a, calculating an actual depth value R of the steel wire rope based on the preset winding and unwinding length and the preset rotation angle of the steel wire rope. In one embodiment, the actual depth value R of the wire rope may be calculated according to the following formula: and R is 180 delta L/(pi delta phi).
And b, comparing the actual depth value with a plurality of preset depth set values, and determining a target depth interval where the actual depth value is located based on the comparison result. In one embodiment, a plurality of depth settings R may be preset i (i 1, 2..) then comparing R to each depth setting, if R is not equal to 1, 2. i <R<R i+1 Then, the target depth interval in which the actual depth value is located is determined as [ R ] i ,R i+1 ]。
And c, determining the minimum depth set value in the target depth interval as the hoisting depth of the steel wire rope. For example, a target depth interval [ R ] i ,R i+1 ]The minimum depth set point is R i Therefore, it can be said that the winding depth of the multi-layer wire rope 3 on the drum shaft 2 is R i I.e. the steel wire rope is at the i-th layer of the winding drum.
In summary, a multi-turn absolute rotary encoder is mounted on the spool shaft, each mechanical position code output by the multi-turn absolute rotary encoder corresponds to one rotation angle, a proximity switch is mounted on the guide wheel support, a code disc is mounted on the guide wheel, and the number of pulses output by the code disc is calculated in the time interval that the proximity switch changes from high level to low level, so that the rotation time of the guide wheel can be obtained. Because the position of the proximity switch on the guide wheel support is fixed, the winding speed of the steel wire rope can be obtained based on the preset winding and unwinding length, and the winding depth of the multilayer steel wire rope can be measured according to the rotating angle of the drum shaft and the winding and unwinding length of the steel wire rope on the guide wheel.
