Description

Technical Field

[0001] The invention relates to the technical field of surface drilling equipment, and in particular to a down-the-hole integrated drilling rig drilling-while-drilling hole protection device. Background Art

[0002] In today's engineering construction field, down-the-hole integrated drilling rigs are widely used in various drilling operations, such as mining, building foundation construction, tunnel excavation, etc. However, during the drilling process, the stability of the hole wall has always been a key issue that plagues the progress and quality of the project.

[0003] After the traditional drilling operation is completed, due to the lack of effective measures to protect the hole while drilling, the hole wall is easily affected by various factors and may collapse. For example, in some areas with complex geological conditions, especially in clay-rich strata, the hole wall is very likely to become unstable after drilling due to the characteristics of clay. On the one hand, clay will swell and soften when it comes into contact with water, causing the hole wall to lose its original support; on the other hand, external environmental factors, such as rain erosion and rolling of mechanical equipment on the construction site, will also damage the drilled hole, thereby affecting the smooth progress of subsequent construction operations such as the placement of detonating charges and the filling of explosives.

[0004] At present, although some drilling rigs on the market are equipped with hole protection devices, they generally have many defects. The structural design of some hole protection devices is unreasonable, the rotation speed is slow and the torque is small when protecting the hole. Once encountering greater resistance, such as when drilling into aquifers or strata with high clay content, the hydraulic motor is easy to stop rotating, seriously affecting the efficiency of hole protection operations. Moreover, the hydraulic system of some hole protection devices is improperly connected to the hydraulic system of the main body of the drilling rig, and the two conflict with each other, which not only interferes with the normal operation of the drilling rig, but also increases the temperature of the hydraulic oil, shortens the service life of the equipment, and increases maintenance costs.

[0017] 1. Compared with the prior art, the present invention can effectively utilize the waste generated by drilling operations through the coordinated work of the uniquely designed hole protection forming components, such as the bending plate, rotating sleeve, feed barrel and scraper, and quickly form a hole protection structure around the drilled hole. The servo motor drives the rotating sleeve through the gear box to rotate the scraper, evenly distributing and scraping the material discharged from the feed barrel outlet to form a hole protection, which greatly improves the efficiency and quality of the hole protection;

[0018] 2. Compared with the prior art, the overall structural design of this device is more reasonable. The combination of the back plate, the slide rail, the slider and the hydraulic cylinder enables the hole protection forming assembly to be flexibly moved to meet the drilling requirements at different positions, thereby forming a higher hole protection structure around the drilled hole and improving the hole protection effect on the drilled hole;

[0019] 3. Compared with the prior art, the structures such as the ring, guide rod, clamping plate and spring in the pressing assembly, after the hole protection structure forms a certain height, when the hole protection assembly moves upward, the clamping plate will move downward, thereby flattening and clamping the top of the hole protection structure, so that the height of the subsequent hole protection structure can be stably increased, thereby improving the hole protection effect of the drill hole;

[0020] 4. Compared with the prior art, the present invention has intelligent monitoring and adaptive adjustment capabilities. The surrounding environment is monitored in real time by infrared distance sensors to prevent external equipment or personnel from approaching and causing damage to the hole protection structure. At the same time, the output torque can be increased by setting the gear box and servo motor to prevent the feed barrel 32 from being unable to rotate due to excessive resistance. When the drilling rig drills into the aquifer, the speed of the servo motor is increased and the rotation direction of the servo motor is changed to shake off the clay. The setting of multiple scraping blocks prevents the clay from adhering to the scraper and the inner wall of the shell.

[0021] 5. Compared with the prior art, the present device integrates a telescopic spraying assembly, which can spray curing agent as needed to enhance the strength and stability of the hole protection structure. It is particularly suitable for special geological conditions such as clay, and the setting of two spraying plates ensures that the curing agent is evenly sprayed on the hole protection structure. When the telescopic spraying assembly is not working, the rectangular box can be closed by using a closing block to avoid the liquid outlet on the spraying plate being blocked.

[0022] To sum up, the down-the-hole integrated drilling rig drilling hole protection device is significantly superior to the existing technology in terms of hole protection efficiency, structural stability, intelligence and multi-functional adaptability. It can effectively solve the problems existing in the existing technology and meet the diverse engineering construction needs. It has extremely high practical value and promotion significance.

Both the rotating ring 46 and the fixed ring 45 are hollow, and the inner wall of the fixed ring 45 is provided with an annular opening. The outer side of the rotating ring 46 passes through the annular opening and extends into the fixed ring 45. The inner space of the rotating ring 46 is connected with the inner wall space of the fixed ring 45, and a sealing gasket is provided between the rotating ring 46 and the upper and lower sides of the annular opening. A liquid storage tank 48 is installed at the upper end of the outer shell 26, and the liquid storage tank 48 is filled with a curing agent, which is a cationic polymer curing agent.

[0035] Among them, the inner tops of multiple rectangular boxes 34 are fixedly connected with pneumatic rods 43, and the telescopic ends of the pneumatic rods 43 are fixedly connected with closing blocks 42. The function of the closing blocks 42 is to close the rectangular boxes 34, so as to prevent clay from clogging multiple liquid outlets on the ejection plate 41.

The diameter of the exhaust pipe 8 is larger than that of the short tube. When the first folded airbag 6 contracts, the gas will enter the second folded airbag 16. At this time, since the diameter of the exhaust pipe 8 is larger than that of the short tube, the gas entering the second folded airbag 16 cannot be discharged quickly, causing the second folded airbag 16 to stretch. At the same time, the volume of the first folded airbag 6 is larger than that of the second folded airbag 16, and the stretching length of the second folded airbag 16 is greater than the upward distance of the device, so that the clamping plate 27 can compress and compact the hole protection structure, and the external gas enters the first folded airbag 6 unidirectionally through the inlet pipe 7, and the gas in the first folded airbag 6 enters the second folded airbag 16 unidirectionally through the exhaust pipe 8.

[0037] Among them, the upper end of the gear box 13 is rotatably connected with a transmission rod 19 and a vertical rod, and the transmission rod 19 is connected to the output shaft of the gear box 13 through a transmission assembly 18. An incomplete gear 20 is provided on the transmission rod 19, and a third gear 21 is provided on the vertical rod. The arrangement of the incomplete gear 20 and the third gear 21 enables the turntable 23 to reciprocate within a range of 135°. The vertical rod is elastically connected to the upper end of the gear box 13 through a torsion spring 24, and the upper end of the vertical rod is fixedly connected with the turntable 23. Two infrared distance sensors 22 are installed on the upper end of the turntable 23. The transmission assembly 18 includes a sprocket arranged on the output shaft of the gear box 13 and the transmission rod 19, and the two sprockets are connected through chain transmission. An alarm is arranged in the controller. When a person or an object approaches the device, the infrared distance sensor 22 generates an electrical signal and transmits it to the controller. The alarm sounds, and the surrounding staff are prompted to handle it.

[0038] The functional principle of the present invention can be explained by the following operation mode: first, the back plate 1 is installed in a suitable position so that the drilling position is located directly below the feed cylinder 32, and then the drilling rod for drilling is passed through the rotating sleeve 14 and the feed cylinder 32, and then the drilling process can be carried out;

[0039] During the drilling process, the servo motor 12 is in operation, and the waste generated by the drilling will be continuously transported upward, so that the waste is discharged from multiple discharge ports 33. The servo motor 12 is operated to drive the second gear 17 to rotate through the gear box 13, and the second gear 17 drives the first gear 15 and the rotating sleeve 14 to rotate, so that the feed barrel 32 drives the multiple scrapers 31 to rotate, so as to evenly scrape the waste and form a hole protection structure around the drilled hole. When the hole protection structure reaches a certain height, the staff can control the hydraulic cylinder 4 to stretch through the controller, so that the entire device moves up a certain height, so that the multiple scrapers 31 scrape the waste again, so that the height of the hole protection structure is increased;

[0040] After each layer of the hole protection structure is formed, the staff controls the pneumatic rod 43 to stretch, so that the multiple closing blocks 42 move up, so that the multiple rectangular boxes 34 are opened away from the side of the feed barrel 32. When the multiple closing blocks 42 move up to the predetermined position, the multiple rectangular boxes 34 are fully opened, and the controller controls the electromagnet 38 to be energized. After the electromagnet 38 is energized, it will generate a repulsive force on the moving block 40, so that the multiple moving blocks 40 move away from the electromagnet 38, and then the moving blocks 40 drive the two ejection plates 41 to move outside the rectangular box 34;

[0041] When the ejection plate 41 is located in the rectangular box 34, the multiple arc springs are in a state. When the ejection plate 41 is moved out of the rectangular box 34, the corresponding two ejection plates 41 will rotate in opposite directions under the elastic action of the arc spring, thereby increasing the angle between the two ejection plates 41. At this time, the pump body 49 is controlled to operate, and the curing agent is extracted and sprayed on the hole protection structure through the ejection plate 41 to accelerate the solidification of the hole protection structure. In the process of hole protection, the feed barrel 32 is in a rotating state, and the drill rod needs to be controlled to stop rotating, so that the waste is no longer transported upward, so that the curing agent can be evenly sprayed on the already formed hole protection structure.

[0042] After a period of time, the control electromagnet 38 is powered off, and under the elastic action of the second spring 39, the moving block 40 drives the two ejection plates 41 to move back. After the two ejection plates 41 enter the rectangular box 34, the arc spring is compressed again, and the pneumatic rod 43 is controlled to contract, so that the rectangular box 34 is sealed again;

[0043] When the curing agent is sprayed, the staff controls the hydraulic cylinder 4 to shrink, so that the entire device moves up a distance, so that the waste continues to accumulate and the height of the hole protection structure is increased;

[0044] When the hydraulic cylinder 4 contracts, the first folded airbag 6 is compressed, and the gas in the first folded airbag 6 enters the second folded airbag 16 through the exhaust pipe 8. Since the diameter of the exhaust pipe 8 is larger than the diameter of the short tube, the gas entering the second folded airbag 16 cannot be completely discharged, which will increase the gas in the second folded airbag 16, thereby stretching the second folded airbag 16 and moving the clamping plate 27 downward. Since the volume of the second folded airbag 16 is smaller than the volume of the first folded airbag 6, the stretched length of the second folded airbag 16 is greater than the height of the entire device moving upward, and the clamping plate 27 squeezes the already formed hole protection structure, flattens and compacts the hole protection structure, and facilitates the subsequent increase in the height of the hole protection structure and improves the strength of the hole protection structure.

[0045] During the operation of the servo motor 12, the output shaft of the gear box 13 rotates through the transmission assembly 18 to drive the transmission rod 19 to rotate, thereby causing the incomplete gear 20 to rotate. When the incomplete gear 20 is engaged with the third gear 21, the vertical rod is driven to rotate through the third gear 21. When the incomplete gear 20 is no longer engaged with the third gear 21, the vertical rod drives the turntable 23 to rotate under the elastic action of the torsion spring 24, thereby causing the two infrared distance sensors 22 to rotate to detect the surrounding environment. When the infrared distance sensor 22 detects that an object or person in the surrounding environment is close to the warning range, the infrared distance sensor 22 generates an electrical signal and transmits it to the controller. The controller alarms to remind people to stay away.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
