Description

Technical Field

[0001] The invention relates to the technical field of water well drilling rigs, in particular to a casing positioning and propulsion device for a water well drilling rig. Background Art

[0002] A water well drilling rig is a mechanical device specially used for drilling water wells. It is usually composed of a power unit, a transmission system, a drill rod, a drill bit and other parts. It can quickly and accurately drill a wellbore of a certain depth and diameter underground to obtain groundwater. The casing pusher is an important component on the water well drilling rig, which is used to push the casing to the required depth during the drilling process. During the drilling process, the casing can prevent the well wall from collapsing, ensure the stability of the wellbore, and can also separate different aquifers to prevent water of different water qualities from mixing.

[0003] In the prior art, when a water well drilling rig is in use, a lifting mechanism is generally used to realize the up and down movement of a power mechanism, a drill rod and a drill bit. When pushing the casing into the borehole, it is first necessary to put an anti-skid chain on the top of the casing, and then connect the anti-skid chain to the lifting mechanism, and pull the anti-skid chain upwards through the lifting mechanism to lift the casing so that the casing remains in a vertical state. Then the lifting mechanism drives the anti-skid chain to slowly descend so that the casing enters the borehole. However, this method is easily affected by other factors, causing the anti-skid chain to shake, and further causing the casing to shake and misalign with the borehole position. At this time, the staff needs to manually support the bottom end of the casing and align it with the borehole to push the casing into the borehole. When the casing accidentally slips during the process of entering the borehole, it will cause serious injury to the construction workers holding the casing, which is not conducive to the life safety of the construction workers. In addition, manual operation is affected by subjective factors and is prone to misalignment, which requires repeated adjustments, thereby affecting construction efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the camera is started, and the real-time image information of the bottom end of the casing body and the ground drilling position is captured by the camera, and the image information is transmitted to the PLC controller for processing. Then the PLC controller transmits the image to the external console by wireless means, and the external console uses computer vision technology to analyze the captured image. When it is found that the bottom end of the casing body is not aligned with the drill hole, the control system will feedback the displacement information to the PLC controller, and then the PLC controller starts the hydraulic cylinder to pull the drilling rig power head, the mounting block and the casing body to move, so that the bottom end of the casing body is aligned with the ground drilling position. By controlling the feed and retraction of the hydraulic cylinder, the bottom end of the casing body can be fine-tuned to achieve alignment with the drill hole, and further achieve accurate positioning of the casing body. Under the action of the connecting component, the firmness of the casing body installation and the stability during movement are improved, and the casing is prevented from accidentally slipping, thereby improving personal safety. Under the action of the positioning component, the position of the casing body is automatically adjusted to achieve accurate positioning, which is not affected by human subjective factors, reduces workload, and improves work efficiency.

[0017] 2. When the present invention is used, the casing body is lifted by an external lifting device, and the casing body is inserted into the connecting ring. The annular electromagnet is started and energized to generate the same magnetism, which pushes the permanent magnet and the T-bar to move, so that the fixing block is inserted into the fixing groove, thereby fixing the casing body on the outer surface of the drill pipe connector. Then the lifting device is separated from the casing body. At this time, the casing body is installed under the mounting block and the rotating block through the connecting assembly, which improves the stability of the casing body installation and reduces shaking and instability during movement.

[0018] 4. When the present invention is used, the casing body is adjusted through the positioning assembly, and the positioning assembly, the connecting assembly and the casing body are driven to move slowly downward through the lifting mechanism. At the same time, the drilling rig power head is started to drive the mounting block and the rotating block to rotate together. Through the cooperation of the T-bar, the annular electromagnet, the permanent magnet and the fixed block, the casing body is driven to rotate, so that the casing body rotates downward into the borehole, thereby improving the propulsion efficiency and reducing the friction resistance, which helps the casing body to be more smoothly advanced into the borehole.

[0019] 3. When the present invention is used, after the casing body enters the borehole to a certain depth, the lifting mechanism and the drilling rig power head are suspended, the annular electromagnet is turned off, the repulsive force disappears, the reset spring loses its thrust, and begins to rebound. Under the pull of the elastic force of the reset spring, the T-bar is pulled to reset, and the fixing block is further pulled away from the fixing groove, so that the casing body is separated from the positioning assembly, which is convenient for disassembling the casing body.

The external control console includes but is not limited to a human-computer interaction interface, a central processing unit, a communication module, a storage module and a power module. The operator issues control instructions through the human-computer interaction interface. The central processing unit is responsible for processing various input information, executing control logic and managing data communication with other components.

Then the PLC controller 308 will control other devices to turn on and off, and the positioning component 2 and the connecting component 3 are driven to move to a high place through the lifting mechanism, and the casing body 304 is lifted by the external lifting equipment, and the top of the casing body 304 is aligned with the connecting ring 305. As the casing body 304 moves upward, the casing body 304 is sleeved on the outer surface of the drill pipe connector 218, and passes through the movable hole 316 and the bottom of the rotating block 306. The annular electromagnet 310 is energized and the magnetism of the annular electromagnet 310 is the same as that of the permanent magnet 312. The annular electromagnet 310 will generate the same magnetism. Under the action of the repulsive force, the plurality of permanent magnets 312 are pushed to move toward the casing body 304, and the plurality of T-shaped rods 311 are pushed to slide inside the corresponding T-shaped slots 318, and the telescopic rod 313 and the return spring 317 are pulled to expand, so that the fixing block 319 is inserted into the fixing slot 320, thereby fixing the casing body 304 on the outer surface of the drill pipe connector 218.

[0027] The effect and working principle of the whole mechanism are as follows: after the casing body 304 is connected to the positioning component 2 through the connecting component 3, the stability of the installation of the casing body 304 is improved, the camera 217 is started in advance, and the real-time image information of the bottom end of the casing body 304 and the ground drilling position is captured by the camera 217, and the image information is transmitted to the PLC controller 308 in the form of electrical signals for processing and recognition, and then the PLC controller 308 transmits the image to the external control console by wireless means, and the external control console uses computer vision technology to analyze the captured image. When it is found that the bottom end of the casing body 304 is not aligned with the drilling hole, the control system will feed back the displacement information to the PLC controller 308, and then the PLC controller The controller 308 will start the hydraulic cylinder 205, pull the connecting block 214 and the second cylinder seat 213 to move, then pull the connecting plate 206 and the reinforcement block 215 to move, further pull the drilling rig power head 208 and the mounting block 209 to move, and further drive the connected casing body 304 to move, so that the bottom end of the casing body 304 is aligned with the ground drilling position, and by controlling the feed and retraction of the hydraulic cylinder 205, the bottom end of the casing body 304 can be fine-tuned to achieve alignment with the drill hole, and further achieve accurate positioning of the casing body 304. Under the action of the connecting component 3, the firmness of the installation of the casing body 304 and the stability during movement are improved, so as to avoid the accidental slipping of the casing, improve personal safety, and Under the action of the component 2, the position of the casing body 304 is automatically adjusted to achieve precise positioning, which is not affected by human subjective factors, reduces workload and improves work efficiency. After the lifting mechanism drives the positioning component 2 and the connecting component 3 to move to a high place, the casing body 304 is lifted by an external lifting device, and the top of the casing body 304 is aligned with the connecting ring 305. As the casing body 304 moves upward, the casing body 304 is sleeved on the outer surface of the drill pipe connector 218, and passes through the movable hole 316 to contact the bottom of the rotating block 306, and then the annular electromagnet 310 is started and energized. The magnetism of the annular electromagnet 310 is the same as that of the permanent magnet 312. The annular electromagnet 310 will produce the same magnetism. Under the action of the repulsive force , push the multiple permanent magnets 312 to move toward the casing body 304, and push the multiple T-shaped rods 311 to slide inside the corresponding T-shaped slots 318, pull the telescopic rod 313 and the return spring 317 to expand, so that the fixing block 319 is inserted into the fixing slot 320, thereby fixing the casing body 304 on the outer surface of the drill pipe connector 218, and then separate the lifting equipment from the casing body 304. At this time, the casing body 304 is installed below the mounting block 209 and the rotating block 306 through the connecting component 3, so as to improve the installation stability of the casing body 304 and reduce shaking and instability. After the installation of the casing body 304 is completed, the casing body 304 is adjusted by the positioning component 2 to align it with the drill hole below, thereby achieving a positioning effect.Then, the positioning assembly 2, the connecting assembly 3 and the casing body 304 are driven to slowly move downward by the lifting mechanism, and the drilling rig power head 208 is started at the same time. The mounting block 209 and the rotating block 306 are driven to rotate together by the rotation of the output end of the drilling rig power head 208, and then the multiple T-shaped rods 311 are driven to rotate inside the connecting ring 305. Under the repulsive magnetic force of the annular electromagnet 310, the fixing block 319 is always inserted in the fixing groove 320. When the T-shaped rod 311 drives the fixing block 319 to rotate, it also drives the casing body 304 to rotate inside the connecting ring 305 and the outer surface of the drill pipe connector 218, and drives the rotating ring 315 to rotate in the annular groove 3 21 rotates, thereby causing the casing body 304 to rotate downward into the borehole, improving the efficiency of advancement and reducing friction resistance, which helps the casing body 304 to be advanced into the borehole more smoothly. When the casing body 304 enters a certain depth in the borehole, the lifting mechanism and the drilling rig power head 208 are suspended, and then the annular electromagnet 310 is closed, the repulsive force disappears, the reset spring 317 loses its thrust and begins to rebound. Under the elastic force of the reset spring 317, the T-bar 311 is pulled to reset, and the fixing block 319 is further pulled away from the fixing groove 320, so that the casing body 304 is separated from the positioning assembly 2, which facilitates the removal of the casing body 304.
