Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of engineering equipment, and relates to a hole-forming drill, in particular to a ductile crawler hole-forming drill for complex disturbances and a control method thereof. Background Art
[0002] At present, many engineering construction sites are located on steep mountain bodies where there are few people and it is difficult to carry out handling work. This undoubtedly causes great difficulties for the drilling and pre-deployment work of the drill. Crawler drills are widely used in engineering construction due to their advantages such as low ground pressure, large traction force, obvious advantages in deep turning and heavy load operation, strong passability and climbing ability.
[0003] However, when a crawler drill travels under overload, it may cause a dangerous accident in which the core iron breaks due to excessive crawler tension. When turning, it is easy to cause the wheel to come off and the core iron to fall off. When climbing steps, cracks will occur at the root of the tread pattern. When walking on the edge of the steps, it will also cause damage to the crawler. In addition, when traveling on a slope road, the crawler may also fall off. Its anti-interference and anti-damage capabilities are limited, and the anti-interference ability of the pre-deployment work of drilling construction is weak, and the probability of being affected by the drilling efficiency in complex terrains is relatively large.
[0004] In addition, after the crawler is damaged, due to its large weight and large volume, it is extremely difficult to replace and repair, and there are relatively large potential safety hazards. Summary of the Invention

[0048] Reference Figure 4 and 5 As shown, a control mechanism 50 is provided at the bottom of the body 10, and the control mechanism 50 is used to control the disconnection of the connector 40.
[0049] The control mechanism 50 includes a control motor 51 and a transmission assembly. The transmission assembly includes a first transmission shaft 52, a second transmission shaft 53, a crank 54 and a connecting rod 55. The control motor 51 is arranged at the bottom of the body 10.

In this embodiment, there is a partial section on the circumferential surface of the stepping driving gear 321 without teeth. During the process of the stepping driving gear 321 driving the stepping driven gear 322 to rotate, when the section without teeth of the stepping driving gear 321 corresponds to the stepping driven gear 322, the stepping driven gear 322 will not rotate, so that the stepping driven gear 322 forms an intermittent rotational motion.

[0056] In this embodiment, the number of the support legs 31 is four. The number of the stepping transmission assemblies 32 and the stepping driving mechanisms 33 is the same as that of the support legs 31 and they correspond one by one. Of course, the number of the support legs 31 can also be more than four.

A first camera for monitoring the surrounding environment is provided at the front end of the body 10, and second cameras for monitoring the crawler chain 22 are provided at both side edges of the body 10. The pressure sensor, the rotational speed sensor, the temperature sensor, the first camera, and the second camera are all communicatively connected to the data processing module on the body 10. The micro data processing module can upload the collected data to the cloud for storage, and the cloud can process and analyze the data. Of course, the collected data can also be stored in a memory card in the body 10 or other storage devices capable of storing data.
[0058] The working principle of the crawler drill provided by the present invention is as follows:
[0059] When the crawler assembly 20 can work normally, the redundant mechanism 30 does not work. When the crawler assembly 20 is damaged and cannot work normally, the control mechanism 50 works to separate the first connecting portion 41 and the second connecting portion 42, so that the crawler assembly 20 falls off from the body 10. At the same time, the legs 31 of the redundant mechanism 30 are deployed and replace the crawler assembly 20 to support the body 10. The stepping drive mechanism 33 of the redundant mechanism 30 works, and the legs 31 can be driven to swing through the stepping transmission assembly 32, so as to drive the drill to move forward step by step. In this way, the working efficiency of the drill is greatly improved. Because when the crawler assembly 20 is damaged, there is no need to stop the drill for repair. Instead, the damaged crawler assembly 20 is automatically detached from the body 10, and then the drill is driven to continue moving forward by the redundant mechanism 30. The detached crawler assembly 20 is then recovered by the staff.
[0060] Embodiment 2
[0061] Embodiment 2 of the present invention provides a control method for a complex perturbation resistant flexible crawler type hole-forming drill, including the following steps:
[0062] S1: Real-time collect the pressure data between the crawler wheel 21 and the crawler chain 22 through the pressure sensor, real-time collect the rotational speed and temperature of the drill drive shaft 24 through the rotational speed sensor and the temperature sensor, real-time collect the road condition information of the surrounding environment through the first camera, and real-time collect the information of the crawler chain 22 through the second camera.
[0063] The collected data can be uploaded to the cloud for storage. This makes it convenient for relevant staff to view the collected data at any time. Of course, the collected data can also be stored in a memory card in the body 10, or other storage devices that can store data.
[0064] S2: Process and analyze each data and determine whether it is normal; if each data is within the normal value range, the drilling rig is operating normally; if any data is abnormal, a braking signal is issued.
[0065] Pressure data is primarily used to analyze the wear of the track wheels 21. As the drive wheel wears, the contact area between it and the track chain 22 decreases, while the contact area between the driven wheel and the track chain 22 increases. This reduces the pressure collected by the pressure sensor. When the pressure drops below a set threshold, an alarm is triggered, and actions are taken based on the damage. The pressure threshold needs to be set based on actual conditions.
[0066] The speed sensor is used to collect the speed of the drive shaft 24. When the speed exceeds a set threshold, an alarm signal is issued and a brake signal is sent to the crawler drive motor to stop driving. The speed threshold needs to be set according to actual conditions.
[0067] The temperature sensor is used to collect the temperature of the drive shaft 24. When the temperature exceeds a set threshold, an alarm signal is issued and a brake signal is sent to the crawler drive motor to stop driving. Generally, the normal operating temperature range can be set to -20°C to 65°C.
[0068] The first camera collects real-time road condition information of the surrounding environment to ensure that the drilling rig can move forward on the correct and reasonable route.
[0069] The second camera captures the track chain 22 in real time and transmits the captured images to a cloud server for processing and analysis to determine its integrity. When the integrity of the track chain 22 falls below a set threshold, an alarm is issued. The track chain 22 integrity threshold can be set to 80%, which refers to 80% of the track chain portion in the image captured by the second camera.
[0070] S3: After the brake signal is issued, the cause is analyzed and the damage status of the drilling rig is determined, and then a treatment plan is given. If the treatment plan requires stopping due to continuous damage, then step S4 is entered to re-plan the plan; otherwise, the brake is released after the fault is eliminated and the drilling rig continues to operate.
[0071] In this embodiment, the integrity of the drill rig is evaluated according to the integrity of the crawler chain or the wear degree of the crawler wheel. If the integrity of the crawler is lower than the threshold value or the pressure measured by the pressure sensor is less than the set threshold value, it indicates that the components of the drill rig are damaged and ineffective, and it is necessary to stop the continuous damage and enter step S4 to re-plan the scheme; if the integrity of the crawler chain is not lower than the threshold value or the pressure measured by the pressure sensor is not less than the threshold value, it indicates that the components of the drill rig do not reach the damage and failure standard, and it is necessary to further troubleshoot according to the information collected by the first camera or / and the second camera. After that, the brake is released and the drill rig continues to run.
[0072] According to the information collected by the first camera or / and the second camera, further troubleshoot according to the following operations, and then release the brake:
[0073] (1) When the value of the temperature sensor exceeds the threshold range, the whole drill rig will first receive the braking command, and judge whether there are obstacles blocking the road conditions through the data information collected by the first camera. If an obstacle is found, re-plan the travel path and restart the drill rig to continue running; judge whether there is foreign matter affecting the rotation of the drive wheel through the information collected by the second camera, and issue a reverse movement command to eliminate the influence of the foreign matter, and re-judge whether the abnormality still exists until the abnormality is eliminated, re-plan the path and restart the drill rig to continue running; if neither of the above two phenomena appears, consider that there is a problem with the drive hardware, and issue an alarm waiting for replacement and repair;
[0074] (2) When the value collected by the speed sensor exceeds the upper threshold, the whole drill rig will first receive the braking command, and judge whether there are obstacles blocking the road conditions through the data information collected by the first camera. If an obstacle is found, re-plan the travel path and restart the drill rig to continue running; when the value collected by the speed sensor exceeds the lower threshold, judge whether there is foreign matter affecting the rotation of the drive wheel through the information collected by the second camera, and issue a reverse movement command to eliminate the influence of the foreign matter, and re-judge whether the abnormality still exists until the abnormality is eliminated, re-plan the path and restart the drill rig to continue running.
[0075] The temperature sensor and the speed sensor complement each other to improve the detection rate of abnormal conditions.
[0076] S4: Disengage the crawler assembly 20 and start the redundant mechanism 30. The redundant mechanism 30 is released to ensure that the drill rig can continue to run.
[0077] The crawler assembly 20 is disengaged from the drill rig body through the connector given in Embodiment 1. At the same time, the redundant mechanism 30 is started to release the support leg 31 to replace the crawler assembly 20 to support the body 10 and move forward step by step.
[0078] In addition, it is also possible to determine whether there are obstacles blocking the road conditions based on the data information collected by the first camera. If an obstacle is found, the traveling path is re-planned and the stepping drive mechanism of the redundant mechanism is activated to control the drill to continue moving forward.
[0079] The control method of the present invention can greatly improve the toughness of the drill. Because when the crawler assembly 20 is damaged and cannot continue to work, the crawler assembly 20 can automatically fall off the body 10, and at the same time, the redundant mechanism 30 is released. The redundant mechanism 30 can drive the drill to move forward step by step. Since the damaged crawler assembly 20 is detached, there is no need for repair and replacement, which better ensures the working efficiency of the drill. Moreover, it has a high degree of intelligence. All data are automatically collected, uploaded to the cloud, and then automatically analyzed and judged. If the data is normal, the drill operates normally. If the data is abnormal, the cause of the abnormality is automatically analyzed and judged, and different treatment plans are given according to different causes.
[0080] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
