So-called tower machine is tower crane.
Below in conjunction with Figure of description, each embodiment of the present invention is described in detail.
Embodiment one:
As shown in Figure 1, be a kind of schematic flow sheet to the method that the mode of operation arranging rope sheave in tower crane detects that the embodiment of the present invention one provides.Described method can be as described below.
Step 101: row's rope sheave that the distance measurement equipment that real-time reception tower crane upper slide bar one end is installed is measured arrives the distance value of described distance measurement equipment.
In a step 101, due to when the lifting mechanism of tower crane runs, the path of motion of row's rope sheave is the other end moving to slide bar from one end of slide bar, one end of slide bar is moved to again from the other end of slide bar, that is, row's rope sheave in tower crane does a kind of back and forth movement on slide bar, and steel rope is suspension hook by the connection of row rope sheave one end, for lifting by crane or transferring weight, and the application force making lift system can lift by crane or transfer weight is the steel rope arranging the connection of the rope sheave other end, steel rope elongates or shortens under the application force of tower crane roller, so just the row's of making rope sheave can do back and forth movement on slide bar.
But because tower crane exists tower height, brachium, once steel rope occurs that disorder cable is worn, service life can reduce greatly, the uncontrollable situation of so easy appearance, adds the danger of tower crane operation.
Therefore, need to detect the state of kinematic motion of row's rope sheave on slide bar, guarantee Timeliness coverage Problems existing, can effectively take measures, avoid dangerous generation.
In one embodiment of the present of invention, a distance measurement equipment has been installed in one end of tower crane upper slide bar, this distance measurement equipment can the row's of measurement rope sheave when moving on slide bar apart from the distance value of self.
In another embodiment of invention, the first distance measurement equipment installed in tower crane upper slide bar one end, and at the second distance measurement equipment that the tower crane upper slide bar other end is installed, first distance measurement equipment measurement obtains arranging the first distance value arriving described first distance measurement equipment when rope sheave moves on slide bar, and the second distance measurement equipment measurement obtains arranging the second distance value arriving described second distance measurement equipment when rope sheave moves on slide bar.
It should be noted that, no matter be the first distance measurement equipment mentioned in the embodiment of the present invention, or the second distance measurement equipment mentioned in the embodiment of the present invention, or the distance measurement equipment mentioned in the embodiment of the present invention, as long as be used for the row's of measurement rope sheave at the distance measurement equipment of the distance value of motion process middle distance self, the technology of the range finding adopted can be infrared technique, can be also ultrasonic technology, not limit here.
It should be noted that, it can be measure in real time apart from the distance value of self that distance measurement equipment measures row's rope sheave when moving on slide bar, can also be gather according to the time cycle of setting, not limit here.
Distance measurement equipment moves once the measurement row of obtaining rope sheave and just sends to control convenience apart from the distance value of self on slide bar, make control convenience can these distance values of Real-time Obtaining, determine to arrange the position of rope sheave on slide bar for subsequent control equipment and kinematic velocity is prepared.
Step 102: according to the multiple distance values received, determines the position of described row's rope sheave on described slide bar and kinematic velocity.
In a step 102, determine that the mode of the position of described row's rope sheave on described slide bar and kinematic velocity includes but not limited to under type:
First kind of way:
Be applied in the scene of described slide bar being installed a distance measuring equipment (DME).
First, often receive a distance value, determine described row's rope sheave be on described slide bar with the position of one end being provided with described distance measurement equipment.
Distinguishingly, when the distance value received is zero, determine that described row's rope sheave moves to the end points place of the one end being provided with described distance measurement equipment on described slide bar.
When the distance value received is the length value of described slide bar, determine that described row's rope sheave moves to the end points place of the opposite end of the one end being provided with described distance measurement equipment on described slide bar.
Such as: when setting row rope sheave installs one end of distance measuring equipment (DME) on slide bar, distance value is 0, when slide bar is not installed the other end of distance measuring equipment (DME), distance value is slide bar length value, suppose that the distance value received successively is 0.1 meter, 0.2 meter, 0.3 meter, as can be seen here, the distance value received is increased to slide bar length value gradually by 0, determine that described row's rope sheave is away from distance measurement equipment, namely arranges the opposite sense motion that the sense of motion of rope sheave on described slide bar is the one end being provided with described distance measurement equipment on described slide bar.
Suppose that the distance value received successively is 1 meter, 0.9 meter, 0.8 meter, as can be seen here, the distance value received is decreased to 0 gradually by slide bar length value, determine that described row's rope sheave is walking close to distance measurement equipment, namely arranging the sense of motion of rope sheave on described slide bar is the end motion being provided with described distance measurement equipment on described slide bar.
It should be noted that, the process of judgement also can be after receiving a distance value, often receives a distance value again and judges once, can determine the state of kinematic motion arranging rope sheave so in time, improve the safety of operation.
Secondly, according to the multiple described distance value received, determine the kinematic velocity of described row's rope sheave on described slide bar, comprising:
Determining that described row's rope sheave is provided with the direction motion of one end of described distance measurement equipment on described slide bar, or when determining that described row's rope sheave is provided with the opposite sense motion of one end of described distance measurement equipment on described slide bar, calculate the difference between adjacent two the described distance values received in real time;
Utilize the difference calculated and the time difference receiving adjacent two described distance values, calculate the real time kinematics speed of described row's rope sheave on described slide bar.
The second way:
The two ends being applied in described slide bar are installed in the scene of a distance measuring equipment (DME) respectively.
In this scene, step 101 is the first distance value of described first distance measurement equipment of row's rope sheave arrival that the first distance measurement equipment of real-time reception tower crane upper slide bar one end installation is measured, and the row's rope sheave receiving the second distance measurement equipment measurement that the tower crane upper slide bar other end is installed arrives the second distance value of described second distance measurement equipment.
First, according to described first distance value received and described second distance value, the described position of row's rope sheave on described slide bar is determined.
Distinguishingly, when described first distance value received be 0, described second distance value be the length value of slide bar time, determine that described row's rope sheave moves to the end points place of the one end being provided with described first distance measurement equipment on described slide bar.
When described first distance value received be the length value of slide bar, described second distance value be 0 time, determine that described row's rope sheave moves to the end points place of the one end being provided with described second distance measurement equipment on described slide bar.
When described first distance value received be the length value of slide bar 1/2nd, described second distance value be the length value of slide bar two/for the moment, determine that described row's rope sheave moves to the point midway place of described slide bar.
In addition, suppose to deduct second distance value for calculating standard with the first distance value, so when the first distance value deduct second distance value be greater than 0 time, determine that the point midway of described row's rope sheave movement position at described slide bar is provided with between the end points of one end of described second distance measurement equipment to described slide bar.
When the first distance value deduct second distance value be less than 0 time, determine that the point midway of described row's rope sheave movement position at described slide bar is provided with between the end points of one end of described first distance measurement equipment to described slide bar.。
Secondly, according to described first distance value received and described second distance value, determine the kinematic velocity of described row's rope sheave on described slide bar, comprising:
Organize in distance value due to each receiving and contain first distance value and a second distance value, now for the two adjacent groups distance value received, the difference calculating the first distance value and second distance value in first group obtains the first difference, and the difference of the first distance value and second distance value obtains the second difference in calculating second group, and utilize the difference between described first difference and described second difference and receive the time difference of two adjacent groups distance value, calculate the kinematic velocity of described row's rope sheave on described slide bar.
Step 103: utilize position on described slide bar of described row's rope sheave of determining and/or kinematic velocity, whether the mode of operation of described row's rope sheave is monitored extremely.
In step 103, the first step, to move to the other end of described slide bar from one end of described slide bar at described row's rope sheave and move to the process of one end of described slide bar from the other end of described slide bar again, judge that whether described row's rope sheave is return movement after moving to any one end points of described slide bar, if not, then second step is performed.
Second step, when one of them end points from described row's rope sheave to described slide bar motion not yet move to this end points namely return time, determine that described row's rope sheave occurs that disorder cable needs to take warning measure.
Particularly, owing to there is back and forth movement when not arriving two end points of slide bar when row's rope sheave moves on slide bar, this situation in actual applications, estimate that reason may be because disorder cable phenomenon appears in described row's rope sheave, therefore, when described row's rope sheave not yet moves to an end points of described slide bar, determine that disorder cable appears in described row's rope sheave, namely the mode of operation arranging rope sheave occurs abnormal, needs prompting that disorder cable alarm occurs.
Meanwhile, judge whether the real time kinematics speed calculated in motion process is greater than the speed threshold of setting and judges whether the time length that described real time kinematics speed is greater than the speed threshold of setting is greater than default time threshold.
3rd step, when the real time kinematics speed calculated in motion process is greater than the speed threshold of setting and the time length that described real time kinematics speed is greater than the speed threshold of setting is less than or equal to default time threshold, determine that described row's rope sheave occurs that disorder cable needs to take warning measure.
It should be noted that, be no matter described row's rope sheave to one of them end points motion of described slide bar not yet move to this end points namely return time, or be greater than the speed threshold of setting when the real time kinematics speed calculated in motion process and the time length that described real time kinematics speed is greater than the speed threshold of setting is less than or equal to default time threshold time, all need to determine that described row's rope sheave occurs that disorder cable needs to take warning measure.
4th step, when the real time kinematics speed calculated in motion process is greater than the speed threshold of setting and the time length that described real time kinematics speed is greater than the speed threshold of setting is greater than default time threshold, determine that described row's rope sheave occurs that warning measure taked by hypervelocity needs.
When the real time kinematics speed that row's rope sheave calculates in motion process within the unit time is greater than the speed threshold of setting, determines that disorder cable appears in described row's rope sheave, remind operator to occur disorder cable phenomenon by modes such as indicator lamp, buzzer phone or read-outs.
Wherein, the speed threshold of setting is less than maxim, can determine according to actual needs, experimentally data can also determine, not limit here.
It should be noted that, unit time is a shorter time, and the kinematic velocity perhaps calculated is V1, and another kinematic velocity of neighborhood calculation is V2 afterwards, V2 is much larger than V1 and be greater than setting threshold value, and overspeed state appears in the row's of explanation rope sheave within the unit time.
Alternatively, when the real time kinematics speed calculated in motion process is greater than the maximum speed of setting and the time length that described real time kinematics speed is greater than the maximum speed of setting is greater than default time threshold, determine that described row's rope sheave needs to take brake measure; Described maximum speed is greater than the speed threshold of described setting.
When the real time kinematics speed calculated in setting-up time is greater than the speed threshold of setting, determine whether the real time kinematics speed calculated is greater than the maximum speed of setting further, and when the real time kinematics speed determining to calculate is greater than the maximum speed of setting, brake measure is taked to described lift system (containing elevator, steel rope and row's rope sheave).
It should be noted that, before whether the real time kinematics speed determining further to calculate is greater than the maximum speed of setting, judge whether the real time kinematics speed calculated in setting-up time continues to be greater than the speed threshold of setting, if so, trigger to perform and determine whether the real time kinematics speed calculated is greater than the operation of the maximum speed of setting further.
When the real time kinematics speed determining to calculate is greater than the maximum speed of setting, brake measure is taked to described lift system, such as: brake activation holds reel tightly, make weight stop overspeed.
When the real time kinematics speed determining to calculate is not more than the maximum speed of setting, send warning information, prompt system occurs abnormal.
By the scheme of the embodiment of the present invention one, row's rope sheave that the distance measurement equipment that real-time reception tower crane upper slide bar one end is installed is measured arrives the distance value of described distance measurement equipment, according to the multiple distance values received, determine the position of described row's rope sheave on described slide bar and kinematic velocity; And utilize position on described slide bar of described row's rope sheave of determining and/or kinematic velocity, whether the mode of operation of described row's rope sheave is monitored extremely, like this by the abnormality detection to the state of kinematic motion of row's rope sheave that tower crane moves, the disorder cable phenomenon that Timeliness coverage occurs or overspeed phenomenon, not only the row's of effectively prevent rope sheave occurs that disorder cable makes the problem of the lost of life of steel rope, also timely overspeed problem to be monitored, improve the safety of tower crane work.
