Detailed Description
The technical scheme provided by the invention is described in more detail below with reference to fig. 1 to 6.
During the running process of the track engineering machine, the track 2 may be inclined. In order to prevent the track 2 from being deflected, the related art is provided with a limiting member at a position of the frame corresponding to the track 2, and the track 2 abuts against the limiting member whenever the track 2 is deflected. The track 2 cannot continue to deflect by physical obstruction of the stop member. Deflection of the track 2 during high speed travel increases driving difficulty, and the track 2 bias tends to increase rolling resistance of the chassis, causing excessive bias of the guide teeth 22 of the track 2, and excessive friction overheating of the weight wheel sets results in degluing, thereby causing additional power loss and product failure. Meanwhile, the deviated chassis affects the quality of bulldozing operation, paving operation and the like.
However, the inventors have found through studies that: not all deflections of the track 2 need to be corrected. Specifically, when the entire machine is turned, the guide teeth 22 and the wheel sets rub against each other, and the deflection of the crawler belt 2 is unavoidable and normal due to the lateral force of the turning. If the deviation of the crawler belt 2 is corrected during turning, the normal turning of the crawler belt 2 can be affected, and the turning accuracy is reduced. The skew that needs to be corrected, which occurs in the crawler belt 2, is referred to herein as abnormal skew, and the skew at the time of turning is referred to as normal skew. Abnormal deflection needs to be corrected, normal deflection does not need to be corrected.
Therefore, when the track engineering machinery turns, the deflection of the track 2 is normal, the related technology cannot distinguish whether the deflection of the track 2 is normal or abnormal, and the deviation rectifying operation is carried out, which is obviously unreasonable.
In view of the foregoing, the following technical solutions are provided in the embodiments of the present invention.
The embodiment of the invention provides a friction type track engineering machine, which comprises a track deviation monitoring system and a driving mechanism 5.
The track deflection monitoring system comprises a track 2, a link plate 1, at least one pair of deflection detection elements 3. As described in detail below.
The drag chain plates 1 are arranged in pairs with a gap 11 between the two drag chain plates 1. The drag link plate 1 is fixedly connected with the third guide wheel assembly 54, specifically by bolts. The guide teeth 22 of the track 2 can pass through the gap 11 independently of the drag chain plate 1.
The crawler belt 2 is wound on the drag chain plate 1, and the drag chain plate 1 is arranged on the frame 6. The crawler belt 2 comprises a crawler belt body 21 and a circle of guide teeth 22 positioned on the inner surface of the crawler belt body 21; the guide teeth 22 are configured to pass through the gap 11. The track body 21 is annular. The drive mechanism 5 drives the crawler belt 2.
At least one pair of deflection detecting elements 3 is mounted to the drag chain plate 1 and is located in the gap 11, the deflection detecting elements 3 being arranged in one-to-one correspondence with the drag chain plate 1. The skew detecting element 3 is configured to detect parameters such as the temperature of the guide teeth 22 to determine whether the track 2 is skewed based on the temperature of the guide teeth 22. The skew detecting element 3 detects in a noncontact manner. The deflection state of the crawler belt 2 can be combined with the running state of the friction type crawler belt engineering machine, and the running state (whether the friction type crawler belt engineering machine is in straight running or turning) of the friction type crawler belt engineering machine at present is combined, so that whether the crawler belt 2 is in normal deflection or abnormal deflection is judged. Moreover, according to the technical scheme, the detection can be performed when the crawler belt is deflected, the detection is timely, the action of other components is not needed, and the detection sensitivity is higher.
In some embodiments, the skew detection element 3 includes one of: a temperature detecting element. The temperature detecting element is used to detect the temperature of the surface of the guide tooth 22. Specifically, referring to fig. 4, the guide tooth 22 has two sides, one of which corresponds to one temperature detecting element and the other of which corresponds to the other temperature detecting element. The two temperature detecting elements detect the temperatures of both sides of the same guide tooth 22.
In some embodiments, the track deviation monitoring system further includes a first controller (not shown) electrically connected to the temperature sensing element; each pair of temperature sensing elements includes two temperature sensing elements, each configured to sense the temperature of one of the sides of the guide tooth 22. The first controller is configured to calculate a temperature difference detected by the two temperature detecting elements to determine whether the crawler belt 2 is deflected.
By calculating the temperature difference detected by the two temperature detecting elements, it is judged whether or not the temperatures of the both side surfaces of the guide tooth 22 are set values. The set value is, for example, 5 ° to 25 °. If the temperature difference is within the set point, it is indicated that the guide teeth 22 are not deflected. If the temperature difference is within the set point, this indicates that the guide teeth 22 are deflected. The positions of the two sides of the guide tooth 22 are one outside and one inside. The outer side refers to the outer side of the working vehicle, and the inner side refers to the center of the working vehicle. The high temperature of the side surface of the guide tooth 22 corresponding to the temperature detecting element near the inner side indicates that the inner side surface of the guide tooth 22 is worn, and the crawler belt 2 is deflected inwards. The high temperature of the side surface of the guide tooth 22 corresponding to the temperature detecting element near the outer side indicates that the outer side surface of the guide tooth 22 is worn, and the crawler belt 2 is deviated outwards.
In other embodiments, the guide teeth 22 are internally embedded with a temperature-changing material component comprising a dye, a color developer, and a solvent. Under the high temperature state, the color-changing dye and the color-developing agent are dissolved and dispersed in the solvent, and the temperature-changing material component presents a specific color state. When the temperature is reduced, the solvent is gradually solidified, and the color-changing dye is structurally changed under the action of the color-developing agent, so that the temperature-changing material component develops color. By adjusting the solidification temperature of the solvent, a temperature-variable material component that changes color at different temperatures can be prepared.
The color of both sides of the same guide tooth 22 can be observed by the worker. The positions of the two sides of the guide tooth 22 are one outside and one inside. The outer side refers to the outer side of the working vehicle, and the inner side refers to the center of the working vehicle. The high temperature of the side surface of the guide tooth 22 corresponding to the color detection element near the inner side indicates that the inner side surface of the guide tooth 22 is worn, and the crawler belt 2 is deflected inwards. The high temperature of the side surface of the guide tooth 22 corresponding to the color detection element near the outer side indicates that the outer side surface of the guide tooth 22 is worn, and the crawler belt 2 is deviated outwards.
The temperature-changing material components have different colors according to different temperatures. If no wear occurs, the temperature of the two sides of the guide tooth 22 are substantially the same, so are the colors of the temperature change material components. If wear occurs, the temperatures of the two sides of the guide tooth 22 are not the same. By collecting and comparing the colors of both sides of the guide teeth 22, it can be judged whether the crawler belt 2 is deflected.
For all the guide teeth 22 of the track 2, the detection of all the guide teeth 22 can be achieved by providing a pair of deflection detecting elements 3, i.e. two deflection detecting elements 3. Specifically, the position of the deflection detecting element 3 is always located in the gap 11 of the link plate 1, and the position of the deflection detecting element 3 is stationary, and all the guide teeth 22 passing through the gap 11 can be detected. According to the technical scheme, detection of all the guide teeth 22 can be achieved by adopting fewer parts, and the detection efficiency is very high.
In other embodiments, the track deviation monitoring system further includes a second controller (not shown) and at least one pair of proximity switches 4. The second controller is electrically connected to the skew detecting element 3. The proximity switch 4 is electrically connected with the second controller; the proximity switch 4 is mounted on the drag chain plate 1 and is adjacent to the deflection detection element 3; the proximity switch 4 is configured to activate the deflection detecting element 3 when the guide tooth 22 is detected upstream of the gap 11.
In the embodiments described above, the first controller and the second controller may use the same controller, and may all use a PLC controller or other implementation manners.
In some embodiments, the track deviation monitoring system further includes a display electrically connected to the deviation detecting element 3 or the controller to display the detection result of the deviation detecting element 3. The display may display the result processed by the controller, or may directly display the detection result of the skew detecting element 3.
The drive mechanism 5 includes a drive wheel 51, a first guide wheel assembly 52 located at the front end of the vehicle, a second guide wheel assembly 53 located at the rear end of the vehicle, and a third guide wheel assembly 54 located between the first guide wheel assembly 52 and the second guide wheel assembly 53.
The driving wheel 51, the first guide wheel assembly 52, the second guide wheel assembly 53 and the third guide wheel assembly 54 each comprise two coaxial wheels which are arranged at intervals, the guide teeth 22 of the crawler belt 2 are positioned between the two wheels, and the guide teeth 22 play a limiting role to prevent the crawler belt 2 from being separated. An edge region of the inner surface of track 2 rubs against the respective wheels of drive wheel 51, first guide wheel assembly 52, second guide wheel assembly 53, and third guide wheel assembly 54. Track 2 is in non-meshed transmission with drive wheel 51. The crawler belt 2 is in contact with the driving wheel 51 under a sufficient tension to perform a static friction transmission, and the guide teeth 22 of the crawler belt 2 perform a guiding function without transmitting a driving force for moving the crawler belt 2. The driving wheel 51 drives the crawler belt 2 to rotate through friction, and other structures except friction force between the driving wheel 51 and the crawler belt 2 are not sampled to realize driving. After the crawler belt 2 rotates, the first guide wheel assembly 52, the second guide wheel assembly 53 and the third guide wheel assembly 54 are driven to rotate by friction force.
Referring to fig. 5 and 6, an embodiment of the present invention provides a track deviation monitoring method, which may be implemented by using the track deviation monitoring apparatus described in the above embodiment. The method comprises the following steps:
step S10, detecting parameters of each of both sides of the guide tooth 22 of the crawler belt 2. In particular, the parameter comprises temperature. For a specific structure of the track 2, reference is made to what has been described in the previous embodiments. How to obtain the parameters of each of the two sides of the guide tooth 22 can also be achieved in the manner described above.
Step S20, judging whether the crawler belt 2 is deflected or not according to the parameters of the two sides of the guide teeth 22 of the crawler belt 2.
The parameters of the two sides of the guide tooth 22 are acquired dynamically in real time in order to judge the condition of the track 2 of the friction track engineering machine in time.
According to the track deviation monitoring method provided by the technical scheme, the eccentric wear condition of the track 2 can be obtained through the parameters of the guide teeth 22 of the track 2, so that excessive eccentric wear of the track 2 is avoided; the crawler belt 2 does not have abnormal deflection, so that the guide teeth 22 cannot rub against each wheel set of the driving mechanism 5, the guide teeth 22 are not easy to excessively wear, and the service life of the crawler belt 2 is ensured; meanwhile, the running rolling resistance of the chassis of the track engineering machinery where the track 2 is positioned is reduced, the maneuvering performance of the whole machine is improved, and the linear running capacity of the chassis is better improved.
In some embodiments, determining whether the track 2 is skewed based on the temperature of each of the two sides of the guide tooth 22 of the track 2 includes the steps of: comparing the difference in temperature of each of the two sides of the guide tooth 22 of the track 2; whether the crawler belt 2 is deflected or not is judged according to the difference value.
Specifically, in some embodiments, a temperature detecting element is employed to detect the temperature of each of the two sides of the guide tooth 22 of the track 2. If the difference is greater than the preset value, the crawler belt 2 is deflected; if the difference is less than or equal to the preset value, no deflection of the track 2 occurs.
In some embodiments, the track deviation monitoring method further comprises the steps of: step S30, when the crawler belt 2 deflects, an alarm signal is sent out.
In some embodiments, prior to step S10, the method further comprises the steps of:
step S40, detecting whether the guide tooth 22 reaches the detection position corresponding to the temperature detection element.
Step S50, if the guide teeth 22 reach the detection positions corresponding to the temperature detection elements, the temperature detection elements are activated to detect the respective temperatures of the two sides of the guide teeth 22 of the crawler belt 2.
In some embodiments, before step S10, further comprising:
step S60, detecting the running parameters of the friction track engineering machinery to which the track 2 belongs. The travel parameter includes a travel speed of the friction track work machine.
Step S70, judging whether the running parameter reaches a starting value. In the event that the driving parameter meets the starting value, the temperature of each of the two sides of the guide tooth 22 of the crawler belt 2 is detected. The starting value is for example 15km/h, and the deflection detecting element 3 can be started to collect the parameter when the running speed of the friction track engineering machine is greater than or equal to 15 km/h.
The step S70 specifically includes the following steps: during a set time, the respective temperature sets of both sides of all the guide teeth 22 passing through the gap 11 are detected. Each temperature set comprises at least two temperature values that are continuously detected; the number of each temperature set is treated as the temperature of each of the two sides of the guide tooth 22.
In some embodiments, using the color of the guide teeth 22 as a determining parameter, determining whether the track 2 is deflected according to the respective parameters of the two sides of the guide teeth 22 of the track 2 specifically includes the following steps: temperature-changing material components are embedded on two side surfaces of the guide teeth 22 of each crawler belt 2; acquiring the colors corresponding to the temperature change material components of the two sides of the guide teeth 22 of the crawler belt 2; whether the crawler belt 2 is deflected is judged according to the color of the temperature change material assembly of the side surface of each guide tooth 22.
Several specific embodiments are described below. An embodiment in which the temperature of the guide teeth 22 is used as a judgment parameter will be described.
The track deviation monitoring method mainly comprises the following steps: monitoring instructions are sent out, monitoring is carried out, early warning feedback is carried out, and four processes of monitoring and termination are carried out.
1) Monitoring instruction sending: in the whole machine debugging stage, a tester sends out a monitoring demand through a display control interface, and a controller receives an instruction.
2) Monitoring and executing: the controller receives the instruction and judges the running speed of the whole machine, and when the running speed is continuously greater than 15km/h, the next step is started to be executed; the proximity switch is powered on to start working, and the temperature detection element is correspondingly triggered to record the temperature of the track guide teeth once when the guide teeth 22 pass, and the two temperature detection elements on the outer side and the inner side record temperature data once when the guide teeth 22 pass until monitoring is finished. Wherein the proximity switch 4 and the temperature detecting element are respectively arranged on the outer side of the chain supporting plate 1a and the inner side of the chain supporting wheel 1b. The outer pallet plate 1a corresponds to the side face A of the guide tooth 22; the inner sprocket wheel 1B corresponds to the side face B of the guide tooth 22. Further, the installation position of the proximity switch 4 is closer to one end of the drive axle than the position of the temperature detection element, so that the proximity switch is guaranteed to be in contact with the guide teeth preferentially, then signals are fed back to the controller, the temperature detection element performs temperature monitoring and recording, and finally the following records are formed in the controller: outside temperature W of guide tooth 22 1 ,W 2 …W n Internal temperature measurement N of guide tooth 22 1 ,N 2 …N n . Wherein, the guide teeth 22 are distributed in the crawler body 21 at intervals, and the number of the guide teeth 22 is not less than 40. n is the number of guide teeth 22, taken as a natural number.
3) Early warning feedback: processing the temperature data on the outer side of the guide tooth 22 and the temperature data in the guide tooth 22, respectively dynamically eliminating the maximum value and the minimum value in real time, and taking the respective average value as the respective temperatures of the inner side surface and the outer side surface of the guide tooth 22; the average values are then compared. When the temperature difference is more than or equal to 15 ℃, displaying early warning, wherein the display interface related indicator lamp changes from green to red and continuously flashes; when the temperature difference is less than 15 degrees, no early warning is displayed, and the display interface related indicator lamp is in evergreen state and continuously blinks until the monitoring is terminated.
Further, if the outside temperature average value of the guide teeth 22 is greater than the inside temperature average value and the temperature difference is greater than or equal to 15 degrees, the early warning display track 2 is deflected outwards; if the outside temperature average of the guide teeth 22 is smaller than the inside temperature average and the temperature difference is 15 degrees or more, the early warning shows that the crawler belt 2 is deflected inwards.
4) Monitoring termination: after receiving the relevant early warning display, the driver can send out a monitoring stopping instruction, and the monitoring execution and early warning feedback function is invalid at the moment, so that the next stop adjustment step can be carried out.
An embodiment in which the color of the guide tooth 22 is used as a judgment parameter will be described below.
And the temperature-changing material components are coated on the two sides of the guide teeth of the crawler belt 2 and can be directly contacted with the wheel groups. The temperature change material component has the following characteristics: when the tissue temperature of the attached temperature-changing material component is lower than 50 ℃, the temperature-changing material component shows green color; when the temperature is above 50 ℃ and below 80 ℃, the temperature-changing material component exhibits an orange color; when the temperature is higher than 80 ℃, the temperature-changing material component appears red.
Further, in addition to the guide teeth 22 being inlaid with a temperature-variable material assembly, the individual wheels of the drive mechanism 5 may also be inlaid with a temperature-variable material assembly, specifically, coated on either side of the drive wheel or the road wheel, respectively. By if the track 2 is off-set, the track is off-set and the temperature on either side of the drive wheel or the bogie wheel is different, i.e. the colour of the temperature change material assembly is different. The eccentric side guide teeth 22 are in direct contact with drive wheel 51 or at least one of the guide wheel assemblies. Due to frictional heat generation, the temperature of drive wheel 51 or the guide wheel assembly increases. The driver can intuitively observe the color change of the driving wheel 51 or the guide wheel assembly to acquire whether the crawler belt is eccentric or not, and can intuitively observe the working state of the crawler belt 2.
