A double-rotation automated drilling rig mainframe

Abstract

The present invention discloses a mainframe of a double-rotation automatic drill rig. The mainframe of the drill rig is arranged on a crawler chassis. The mainframe of the drill rig includes a drilling rotary disc and a drill pipe rotary disc which are respectively arranged on the crawler chassis through rotary supports. A drilling mechanism, an angle adjustment mechanism and a support and fixation mechanism are arranged on the drilling rotary disc. In the retracted state, the drilling mechanism extends from the middle of the drilling rotary disc to the upper left of the mainframe of the drill rig. The drilling rotary disc can rotate ±90° around its left-right direction center line, thereby driving the drilling mechanism to rotate to the target operation position. A drill pipe box and a multi-axis manipulator are successively arranged on the drill pipe rotary disc from left to right. The drill pipe rotary disc can rotate ±90° around its left-right direction center line so that the multi-axis manipulator can grab a drill pipe from the drill pipe box and send it into the drilling mechanism or take out the drill pipe from the drilling mechanism and put it back into the drill pipe box. The drill rig using this mainframe can meet the requirements of convenient drilling angle adjustment, convenient drill pipe grasping, flexible drilling operation and large drill pipe storage capacity.

Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and specifically relates to a main body of a double-rotation automatic drilling rig. Background Art

[0002] With the progress of science and technology, the technical level of drilling engineering equipment has also entered a stage of rapid development. Now, more and more drilling equipment has developed into automatic drilling equipment, which has functions such as automatic drilling and automatic drill pipe withdrawal. For underground coal mines, there are also many automatic drilling equipment. These equipment have played a great role in improving on-site operation efficiency, reducing personnel input, and reducing the labor intensity of workers. However, these equipment also have certain problems. Most of the automatic drilling equipment currently used underground is divided into two structures. One form is an integrated machine design, which is convenient to operate, but has a small drill pipe reserve. The other is a split machine design, where the drill pipes are grabbed by a separate drill pipe vehicle and a manipulator. The drill pipe reserve is large. However, due to the split design and requirements such as meeting the needs of the manipulator for drill pipe feeding, the drilling angle of the equipment is limited to a certain extent. Summary of the Invention

[0003] In order to solve the deficiencies in the prior art, the present invention provides a main body of a double-rotation automatic drilling rig. The drilling rig using this main body can meet the requirements of convenient drilling angle adjustment, convenient drill pipe grasping, flexible drilling operation, and large drill pipe reserve.

[0004] In order to achieve the above object, the specific solution adopted by the present invention is as follows:

[0005] A main body of a double-rotation automatic drilling rig, the main body of the drilling rig is arranged on a crawler chassis. The main body of the drilling rig includes a drilling rotary disk and a drill pipe rotary disk which are respectively arranged on the crawler chassis through slewing bearings. A drilling mechanism for drilling, an angle adjustment mechanism for adjusting the operation angle of the drilling mechanism, and a support and fixation mechanism for adjusting the drilling height of the drilling mechanism are arranged on the drilling rotary disk. In the retracted state, the drilling mechanism extends from the middle of the drilling rotary disk to the upper left of the main body of the drilling rig. The drilling rotary disk can rotate ±90° around its left-right direction center line to drive the drilling mechanism to rotate to the target operation position. A drill pipe box capable of placing multiple drill pipes and a multi-axis manipulator capable of sequentially grasping drill pipes through the cooperation of multiple joints are arranged on the drill pipe rotary disk from left to right. The drill pipe rotary disk can rotate ±90° around its left-right direction center line so that the multi-axis manipulator can grasp drill pipes from the drill pipe box and send them into the drilling mechanism or take out the drill pipes from the drilling mechanism and put them back into the drill pipe box.

[0006] Furthermore, the support and fixation mechanism includes two columns fixed on the drilling rotary disk and a column cross beam arranged between the two columns. The two columns are respectively located on both sides of the drilling mechanism. Both ends of the column cross beam are respectively lifted by a lifting oil cylinder to realize the lifting of the drilling mechanism along the columns.

[0007] Furthermore, the drilling mechanism includes a power head with a chuck for installing and controlling the movement of the drill pipe, a gripper for gripping the drill pipe, and a guide rail assembly for driving the power head to move back and forth. Both the power head and the gripper are arranged on the guide rail assembly. The guide rail assembly includes a guide rail bracket and a guide rail arranged above the guide rail bracket. One end of the guide rail bracket is hinged to the column cross beam, and the power head is slidably arranged on the guide rail and can move along the guide rail.

[0008] Furthermore, the angle adjustment mechanism includes an angle adjustment oil cylinder, two diagonal braces, and two hydraulic clamps. The two ends of the angle adjustment oil cylinder are respectively hinged to the drilling rotary disc and the guide rail bracket. By the action of the angle adjustment oil cylinder, the adjustment of the elevation angle of the guide rail assembly can be realized. The diagonal braces and the hydraulic clamps are both arranged on both sides of the guide rail assembly. One end of each diagonal brace is hinged to the drilling rotary disc. Each hydraulic clamp is slidably connected to the corresponding diagonal brace, and a locking mechanism is arranged between the two. Both hydraulic clamps are connected to the guide rail bracket.

[0009] Furthermore, a plurality of partitions are arranged at intervals on the opposite inner side walls of the drill pipe box, and the space between two adjacent partitions can only accommodate one drill pipe.

[0010] Furthermore, the drill pipe rotary disc includes a square part and an arc part integrally formed with one side wall of the square part. The drill pipe box is arranged on the square part, and the multi-axis manipulator is arranged on the arc part.

[0011] Beneficial effects:

[0012] In the drilling rig main body of the present invention, by providing a drill pipe rotary disc and a drilling rotary disc, a drill pipe box and a multi-axis manipulator are arranged on the drill pipe rotary disc. Among them, the drill pipe box can store multiple drill pipes to achieve the purpose of large-capacity storage of drill pipes. The multi-axis manipulator can grab drill pipes one by one from the drill pipe box and send them into the drilling mechanism or take out the drill pipes from the drilling mechanism and put them back into the drill pipe box through its own adjustment and rotation. The multi-axis manipulator can operate without dead angles in multiple dimensions to achieve the purpose of convenient grabbing of drill pipes, avoiding the problems that the conventional manipulator structure restricts the drilling angle and drilling position of the drilling rig. At the same time, a drilling mechanism, an angle adjustment mechanism, and a support and fixing mechanism are arranged on the drilling rotary disc. Through the coordinated action of the three mechanisms and the drilling rotary disc, the purposes of adjusting the drilling angle, adjusting the drilling opening height, automatic drilling, and automatic drill withdrawal operation of the drilling rig main body can be achieved. The present invention realizes the integrated design of the drilling rig main body through the double-rotation design, and can simultaneously meet more drilling angle and position requirements.

[0018] It should be noted that the terms "include" and "have" and any variations thereof in the present invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0019] First of all, it should be said that the main technical solution protected by the present invention is the main drilling rig, and when it is used, it also needs to be used in combination with a control mechanism, an operating platform, etc.

[0020] A double-rotation automatic main drilling rig, the main drilling rig is arranged on the crawler chassis 1, please refer to Figures 1 to 2 , Figure 1 As shown, it is the walking state (also known as the retracted state) diagram of the main drilling rig, Figure 2 As shown, it is the state diagram when the main drilling rig is working (rotate the drilling rotary table 2 in Figure 1 backward by 90° along its left-right direction center line, and rotate the drill pipe rotary table 12 forward by 90° along its left-right direction center line to obtain Figure 2), the main rig includes a drilling rotary table 2 and a drill pipe rotary table 12 that are respectively arranged on the crawler chassis 1 through slewing bearings. A drilling mechanism for drilling, an angle adjustment mechanism for adjusting the operating angle of the drilling mechanism, and a support and fixation mechanism for adjusting the drilling height of the drilling mechanism are provided on the drilling rotary table 2. In the retracted state, the drilling mechanism extends from the middle of the drilling rotary table 2 to the upper left of the main rig. The drilling mechanism can achieve the functions of automatic drilling and automatic drill withdrawal through the control of the control mechanism; the drilling rotary table 2 can rotate ±90° around its left-right direction center line to drive the drilling mechanism to rotate to the target operating position, and can achieve the adjustment of the azimuth angle during the operation of the rig; on the drill pipe rotary table 12, a drill pipe box 13 capable of placing multiple drill pipes and a multi-axis manipulator 11 capable of grasping drill pipes one by one through the cooperation of multiple joints are arranged in sequence from left to right. The drill pipe rotary table 12 can rotate ±90° around its left-right direction center line so that the multi-axis manipulator 11 can grasp the drill pipes from the drill pipe box 13 and send them into the drilling mechanism or take out the drill pipes from the drilling mechanism and put them back into the drill pipe box 13. Specifically, a plurality of partitions are arranged at intervals on the opposite side walls inside the drill pipe box 13. The space between two adjacent partitions can only place one drill pipe. The drill pipe box 13 can store multiple drill pipes to meet the drilling requirements of the rig. At the same time, the drill pipes are separated by partitions, which is convenient for the multi-axis manipulator 11 to grasp the drill pipes one by one.

[0021] It should be noted that Figure 2 This is only one of the working state diagrams of the main rig of the drill. The main rig of the drill can rotate the corresponding rotary table to the target position according to the actual working conditions.

[0022] Specifically, the support and fixation mechanism includes two columns 9 fixed on the drilling rotary table 2 and a column cross beam arranged between the two columns 9. The two columns 9 are respectively located on both sides of the drilling mechanism. The two ends of the column cross beam are respectively lifted by a lifting oil cylinder to realize the lifting of the drilling mechanism along the column 9.

[0023] Among them, the drilling mechanism includes a power head 10 with a chuck for installing the drill pipe and controlling the movement of the drill pipe, a gripper 7 for clamping the drill pipe, and a guide rail assembly for driving the power head 10 to move back and forth. The power head 10 and the gripper 7 are both arranged on the guide rail assembly; the guide rail assembly includes a guide rail support 6 and a guide rail 8 arranged above the guide rail support 6. One end of the guide rail support 6 is hinged on the column cross beam. The power head 10 is slidably arranged on the guide rail 8 and can move along the guide rail 8.

[0024] Specifically, the angle adjustment mechanism includes an angle adjustment oil cylinder 3, two diagonal braces 4, and two hydraulic clamps 5. Both ends of the angle adjustment oil cylinder 3 are hinged to the drilling rotary table 2 and the guide rail support 6 respectively. By the action of the angle adjustment oil cylinder 3, the adjustment of the elevation angle of the guide rail assembly can be realized. The diagonal braces 4 and the hydraulic clamps 5 are both arranged on both sides of the guide rail assembly. One end of each diagonal brace 4 is hinged to the drilling rotary table 2. Each hydraulic clamp 5 is slidably connected to the corresponding diagonal brace 2, and a locking mechanism is provided between the two. Both hydraulic clamps 5 are connected to the guide rail support 6.

[0025] It should be noted that the drill pipe rotary table 12 includes a square part and an arc part integrally formed with one side wall of the square part. The drill pipe box 13 is arranged on the square part, and the multi-axis manipulator 11 is arranged on the arc part. The drill pipe box 13 and the multi-axis manipulator 11 are both located on the drill pipe rotary table 12, so that their relative positions are fixed, reducing the positioning process during the operation of the multi-axis manipulator 11 and improving the operation efficiency.

[0026] Specifically, the crawler chassis 1 includes a crawler traveling mechanism and outrigger cylinders. The free movement of the equipment is realized through the crawler chassis 1, improving the moving efficiency of the drilling rig. At the same time, the upward support function of the drilling rig is realized through the outrigger cylinders arranged at the four corners of the crawler chassis 1.

[0027] When the main machine of the drilling rig works, rotate both the drilling rotary table 2 and the drill pipe rotary table 12 to appropriate positions, so that the drilling mechanism faces the side wall of the roadway, and the multi-axis manipulator 11 is also at the side wall of the roadway. After the angle adjustment and drilling stabilization of the drilling rig are completed, the multi-axis manipulator 11 grabs a drill pipe from the drill pipe box 13 and sends it to the middle part of the drilling mechanism. After the reducer connects the drill pipe, the multi-axis manipulator 11 returns to its original position, grabs another drill pipe and waits for the next drilling. After the drilling mechanism connects the new drill pipe, it automatically drills. After the drilling is completed, the multi-axis manipulator 11 sends the next drill pipe; when withdrawing the drill pipe, the drilling mechanism loosens the drill pipe, and the multi-axis manipulator 11 grabs the withdrawn drill pipe from the drilling mechanism and sends it back to the drill pipe box 13 until the operation is completed. If the equipment needs to construct the other side, only the rotation angles of the two rotary tables need to be adjusted, and the drilling mechanism and the multi-axis manipulator 11 are rotated to the other side.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced by referring to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of the claims pending for approval.
