Description

Technical Field

[0001] The invention relates to the technical field of drill rod transportation, in particular to a drill rod installation and transportation mechanism of a drilling rig. Background Art

[0002] A drilling rig is a complex machine consisting of a machine, a unit and a mechanism. A drilling rig is a mechanical device that drives the drill tool underground to obtain physical geological data during the exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.). It is also called a drilling machine. The main function is to drive the drill tool to break the rock at the bottom of the hole and lower or pull out the drill tool in the hole. It can be used to drill cores, ore cores, rock cuttings, gas samples, liquid samples, etc. to explore underground geology and mineral resources. During the drilling process, as the drilling depth increases, the drilling rig needs to intermittently increase the length of the drill rod to meet the drilling needs.

[0003] The Chinese patent with announcement number CN218542189U, a geological drilling drill rod conveying structure, belongs to the field of drill rod conveying technology, and includes a conveying structure. The conveying structure includes a horizontal conveying component, a vertical conveying component and an adjustable receiving component. The horizontal conveying component includes a first support frame, a first gear, a first chain, a second gear, a first motor, a first crawler, a first driving wheel, a second driving wheel and a rubber anti-slip protrusion. The discharge port of the horizontal conveying component is connected to a vertical conveying component.

[0004] In the above scheme, the drill rod conveying structure can convey the drill rods one by one to the required height according to needs, and the conveying flexibility is high. However, it has the following disadvantages: since the outer wall of the drill rod is an arc surface, the drill rod is prone to rolling and sliding during the conveying process of the drill rod, which makes the drill rod easy to fall from the conveying device and be damaged, thereby reducing the stability and use effect of the drill rod conveying device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the cooperation of the storage bin, the first cylinder and the second cylinder, the stored drill rods can be indirectly and stably transported under the action of the installation frame, effectively preventing the drill rods from shaking or falling during transportation, and realizing automatic, orderly and stable transportation of the drill rods, reducing the time and workload of manual handling and adjustment, and improving the storage and transportation efficiency of the drill rods, thereby meeting the needs of drilling work. At the same time, the guide plate can limit and guide the drill rods transported by the conveying assembly, so that the drill rods after transportation can fall stably onto the clamping mechanism, thereby facilitating the installation of the drill rods. The blocking block can be used to block and limit the drill rods during transportation, effectively preventing the drill rods from falling from the clamping groove due to the movement potential energy of the installation frame, so that the drill rods can be stably transported;

[0016] Second, through the cooperation of the sliding block and the sliding hole, precise guidance can be provided for the up and down movement of the mounting frame, so that the mounting frame can accurately move along the preset direction during the movement, preventing the mounting frame from tilting, offsetting, etc., thereby improving the transportation stability of the drill rod. At the same time, the cooperation of the sliding block and the sliding hole can improve the bearing capacity of the mounting frame, so that the mounting frame can stably bear the drill rod and prevent the mounting frame from being deformed or damaged due to uneven force. Through the cooperation of the limit block and the rubber pad, the horizontally moving mounting frame can be limited to prevent the mounting frame from exceeding its normal working range during the movement, and avoid the mounting frame from colliding with other equipment or components, thereby protecting the safety of the mounting frame and other equipment. At the same time, when the mounting frame moves to the extreme position or encounters a sudden impact force, the rubber pad can play a role in buffering and shock absorption. The rubber pad has good elasticity and damping characteristics, which can absorb and dissipate the kinetic energy of the mounting frame, reduce the damage to the mounting frame and other components caused by the impact force, and extend the service life of the equipment;

[0017] 3. The clamping mechanism can be driven to move to the installation position by the third cylinder. Different drilling rig models and working scenarios may have different requirements for the installation position and angle of the drill rod. The third cylinder drives the clamping mechanism to move, and the position and posture of the clamping mechanism can be flexibly adjusted according to actual work needs, so that the drill rod can adapt to different installation requirements. Through the cooperation of the clamping cylinder and the clamping plate, the drill rod can be accurately positioned and fixed in the specified position as needed to ensure that the drill rod is tightly and accurately connected to other parts of the drilling rig. The clamping cylinder drives the clamping plate to apply a stable clamping force to the drill rod, and firmly fix the drill rod in the installation position to prevent the drill rod from shaking, offset or rotating during the installation process, thereby ensuring the accuracy and quality of the drill rod installation. At the same time, the drive motor can flexibly adjust the angle of the clamping frame according to the installation requirements, so that the drill rod can meet the installation requirements of different angles, thereby improving the flexibility of the drill rod;

[0018] Fourth, the rollers can make the drill rod move easily between the clamping frame and the clamping plate, so that the staff can push or pull the drill rod to make it roll on the rollers, so as to adjust the position of the drill rod conveniently and improve the accuracy and efficiency of the drill rod installation. At the same time, the setting of the rollers can convert the sliding friction between the drill rod and the clamping frame into rolling friction, which greatly reduces the friction force, makes the movement of the drill rod smoother, and protects the surface quality of the drill rod. Through the cooperation of the lifting hydraulic cylinder and the load-bearing plate, the four corners of the box can be supported, which can effectively disperse the weight of the drill rod, so that the drill rod on the box can remain horizontal and stable during the transportation process, and prevent the drill rod from colliding and deviating due to the shaking of the box, so as to ensure the safety and accuracy of the drill rod transportation. At the same time, different working scenes and installation requirements may require the drill rod to be transported and installed at different heights. The lifting hydraulic cylinder can flexibly adjust the height of the box according to actual needs, so that the drill rod can be accurately docked with other parts of the drilling rig, which is convenient for the installation operation of the drill rod.

[0029] In use, through the cooperation of the storage bin 2, the first cylinder 7, and the second cylinder 14, the stored drill rods can be indirectly and stably transported under the action of the installation frame 15, effectively preventing the drill rods from shaking or falling during transportation, and realizing automatic, orderly and stable transportation of the drill rods, reducing the time and workload of manual handling and adjustment, and improving the storage and transportation efficiency of the drill rods, thereby meeting the needs of drilling work. At the same time, the guide plate 36 can limit and guide the drill rods transported by the transport assembly, so that the transported drill rods can fall stably onto the clamping mechanism, thereby facilitating the installation of the drill rods.

The buffer mechanism includes a plurality of limiting blocks 20 fixed on the top surface of the box body 1, and a rubber pad 21 is fixed on one side of the limiting block 20, and the rubber pad 21 is in contact with the mounting frame 12.

[0031] During use, the cooperation between the sliding block 18 and the sliding hole 19 can provide precise guidance for the up and down movement of the mounting frame 12, so that the mounting frame 12 can move accurately along the preset direction during the movement, preventing the mounting frame 12 from tilting, offsetting, etc., thereby improving the transportation stability of the drill rod. At the same time, the cooperation between the sliding block 18 and the sliding hole 19 can improve the carrying capacity of the mounting frame 12, so that the mounting frame 12 can stably carry the drill rod, and prevent the mounting frame 12 from being deformed or damaged due to uneven force.

The rubber pad 21 has good elasticity and damping characteristics, can absorb and dissipate the kinetic energy of the mounting frame 12, reduce the damage to the mounting frame 12 and other components caused by the impact force, and extend the service life of the equipment.

[0033] In use, the clamping mechanism can be driven to move to the installation position by the third cylinder 24. Different drilling rig models and working scenarios may have different requirements for the installation position and angle of the drill rod. The third cylinder 24 drives the clamping mechanism to move, and the position and posture of the clamping mechanism can be flexibly adjusted according to actual work requirements, so that the drill rod can adapt to different installation requirements. Through the cooperation of the clamping cylinder 29 and the clamping plate 30, the drill rod can be accurately positioned and fixed in the specified position as needed to ensure that the drill rod is tightly and accurately connected to other parts of the drilling rig. The clamping cylinder 29 drives the clamping plate 30 to apply a stable clamping force to the drill rod, and the drill rod is firmly fixed in the installation position to prevent the drill rod from shaking, deflecting or rotating during the installation process, thereby ensuring the accuracy and quality of the drill rod installation.

At the same time, the setting of the roller 32 can convert the sliding friction between the drill rod and the clamping frame 27 into rolling friction, greatly reducing the friction force, making the movement of the drill rod smoother and protecting the surface quality of the drill rod. Through the cooperation of the lifting hydraulic cylinder 34 and the load-bearing plate 35, the four corners of the box 1 can be supported, which can effectively disperse the weight of the drill rod, so that the drill rod on the box 1 can remain horizontal and stable during the transportation process, and prevent the drill rod from colliding, deviating, etc. due to the shaking of the box 1, so as to ensure the safety and accuracy of the drill rod transportation.
