Among them, integrated drilling rigs are automatic drilling rigs, and their upper and lower rods are all automated operations, without the need for manual lifting of the rods. Split drilling rigs are manual drilling rigs, and the installation and removal of their drill rods require manual operation. A drill rod is longer than a person's height and weighs 80 kilograms. In a drilling and punching operation, more than one drill rod is required. If the rods are manually raised one by one and then lowered after the drilling is completed, the whole process is time-consuming and labor-intensive, and the efficiency is low. In addition, once a human error is made, the drill rod may accidentally injure personnel, and there are certain safety hazards. Therefore, for the existing split drilling rigs, it is necessary to design an auxiliary device to assist the existing split drilling rigs in the operation of raising and lowering the rods, so as to solve the defects of the existing split drilling rigs, such as the difficulty in installing and disassembling the drill rods, the labor-intensiveness, the low efficiency, and the low safety.

[0040] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0041] See also Figures 1 to 16 In a preferred embodiment of the present invention, an automatic rod-raising auxiliary device for a split-type drilling rig includes a main base 1, a clamping assembly and a drill rod placement assembly 6.

[0042] The clamping assembly is installed on the main base 1, and the clamping assembly includes a lower clamping structure 2, an upper clamping structure 3, an angle adjustment structure 5 and a lifting drive structure 4, which is used to clamp the drill rod 9 and cause the drill rod 9 to separate from the feed device body 8 of the drilling rig.

[0043] Specifically, the lower clamping structure 2 is installed above the main base 1, and its clamping opening is located directly below the clamping opening of the upper clamping structure 3; the lower clamping structure 2 is used to clamp and fix the drill rod 9 located in the drill hole to make it fixed, so that it is convenient for the feed device body 8 of the drilling rig to drive the drill rod 9 connected to it and located above it to rotate, thereby realizing the separation of the two connected drill rods 9. In the present invention, the lower clamping structure 2 is used to realize the clamping of the drill rod 9, and there is no special design in the form of its clamping structure. It can be as shown in the attached Figure 1 The clamping structure shown is the same as the upper clamping structure 3, or it may be other clamping structures, and there is no specific limitation on this.

[0044] The upper clamping structure 3 is slidably mounted on the main base 1 through the lifting drive structure 4, and its sliding direction is the up and down direction; the upper clamping structure 3 includes an upper clamping fixed seat 3.1, two upper clamping plates 3.3 and an upper clamping drive motor 3.2, the upper clamping fixed seat 3.1 is installed with an upper clamping drive motor 3.2, the output shaft of the upper clamping drive motor 3.2 is connected to the two upper clamping plates 3.3, and the two upper clamping plates 3.3 are rotatably mounted on the upper clamping fixed seat 3.1, and the two are driven by the upper clamping drive motor 3.2 to rotate in opposite directions to form a clamping opening for clamping or move away from each other to open the clamping opening, and the clamping surface of each upper clamping plate 3.3 is an arc surface, on which a plurality of rollers 3.4 and a plurality of elastics are arranged at intervals. Airbag 3.5, all rollers 3.4 partially protrude from the arc surface and the protruding ends are located on the same arc surface, each elastic airbag 3.5 is connected to an air inlet pipe (not shown), and is connected to an air charging and discharging air source device (not shown) through the air inlet pipe, and one end of each elastic airbag 3.5 not connected to the arc surface is located between the protruding end of the roller 3.4 and the arc surface in an uninflated state, and is closer to the center of the arc surface than the protruding end of the roller 3.4 in an inflated state; the upper clamping fixed seat 3.1 is connected to the angle adjustment structure 5, and is installed on the lifting drive structure 4 through the angle adjustment structure 5, and the angle adjustment structure 5 drives the upper clamping fixed seat 3.1 to rotate on the lifting drive structure 4, and the rotation axis is perpendicular to the lifting direction of the lifting drive structure 4.

[0045] The upper clamping structure 3 can clamp the drill rod 9 outside the drill hole, and the elastic airbag 3.5 on the upper clamping plate 3.3 is inflated and deflated to achieve stable clamping and release, and the upper clamping plate 3.3 is driven by the upper clamping drive motor 3.2 to realize the opening and closing of the clamping plate, thereby realizing the clamping and release of the drill rod 9, wherein the upper clamping drive motor 3.2 is used to drive the upper clamping plate 3.3 to rotate to achieve the clamping method, which is convenient for placing the drill rod 9 from one side to the spatial position where the two upper clamping plates 3.3 are clamped when the rod is put up, and then the upper clamping drive motor 3.2 drives the two upper clamping plates 3.3 to merge, so that the drill rod 9 can be clamped. Preferably, the end of the elastic airbag 3.5 that is not connected to the arc surface is provided with an anti-slip convex point to improve the stability of clamping.

[0046] Secondly, the upper clamping structure 3 of the present invention is tilted by the adjustment of the angle adjustment structure 5, so that the upper clamping structure 3 can clamp the tilted drill rod 9. At the same time, the tilting adjustment method is also convenient for converting the clamped drill rod 9 from a vertical state to a tilted state. In this way, after the elastic airbag 3.5 is deflated, the tilted drill rod 9 is loosened and slides down under the action of its own weight. Since the roller 3.4 structure is provided on the upper clamping plate 3.3, the friction force on the drill rod 9 is small and it can slide down automatically, thereby realizing the lowering operation of the drill rod 9, that is, avoiding the drill rod 9 from being artificially separated from the feed device body 8 of the drilling rig and lifted down, reducing the manual work and improving the operation safety. In this embodiment, the angle adjustment structure 5 is an angle adjustment motor, which is installed on the movable end of the lifting drive structure 4, and its output shaft is connected to the upper clamping fixed seat 3.1.

[0047] Furthermore, the present invention also assists the upper clamping structure 3 to adjust the clamping position, lift and lower the drill rod 9, and other operations by setting the lifting drive structure 4. 3.3, the upper clamping plate 3 is used to hold the drill rod 9 in place and the lower clamping plate 3 is used to hold the drill rod 9 in place. For another example, when it is necessary to lower the rod, the feed device body 8 of the drilling rig drives the drill rod 9 out of the hole, one of the drill rods 9 is completely located above the drill hole, called the upper drill rod 9, and the upper end of the other drill rod is located above the drill hole, called the lower drill rod 9. At this time, the lower clamping structure 2 clamps the lower drill rod 9, and the feed device body 8 of the drilling rig drives the upper drill rod 9 to rotate and rise to separate from the lower drill rod 9, and then the upper clamping structure 3 clamps the upper drill rod 9, the feed device body 8 of the drilling rig moves up and separates from the upper drill rod 9, and the lifting drive structure 4 drives the upper drill rod 9 to move up until it is completely separated from the lower drill rod 9, and the angle The adjustment structure 5 then drives the upper drill rod 9 to rotate and tilt, the elastic airbag 3.5 of the upper clamping structure 3 is deflated, the upper drill rod 9 contacts the roller 3.4, and the upper drill rod 9 slides down to the specified position under the action of its own weight. After the upper drill rod 9 is completely separated from the upper clamping structure 3, the angle adjustment structure 5 prompts the upper clamping structure 3 to reset, the upper clamping plate 3.3 of the upper clamping structure 3 is opened, and the feed device body 8 of the drilling rig moves down to dock with the lower drill rod 9, repeating the above actions to perform the next round of rod lowering operation, and repeating multiple times to achieve the rod lowering operation of the drill rod 9. In this embodiment, the lifting drive structure 4 includes but is not limited to one of a screw-motor assembly, an electric telescopic cylinder, a pneumatic telescopic cylinder, a hydraulic cylinder, and a linear stepping motor.

[0048] In summary, the present invention can realize the automatic raising and lowering of the drill rod 9 through the cooperation of various structures, without the need for human participation in the entire process, which to a certain extent reduces the workload of manual labor, improves work efficiency, and can improve work safety.

[0049] In the present invention, a drill rod placement assembly 6 is also provided to facilitate the collection of the drill rods 9 of the lower rod and the auxiliary upper rod. Specifically, the drill rod placement assembly 6 is provided on one side of the main body base 1, and includes a placement base 6.1, a placement frame 6.2 and a tilting drive 6.3; the placement frame 6.2 is installed on the placement base 6.1, one end of which in the length direction is hinged to the placement base 6.1, and the other end is connected to the tilting drive 6.3, and the tilting drive 6.3 drives the other end of the placement frame 6.2 to lift so that the placement frame 6.2 is tilted. When tilted, the frame opening of the placement frame 6.2 faces the lower clamping structure 2 and the lower clamping structure 2.

[0050] In the drill rod placement assembly 6, a placement frame 6.2 is used to place the drill rod 9. The placement frame 6.2 is tilted so that the drill rod 9 in the placement frame 6.2 can be tilted, which is convenient for manually taking the drill rod 9 and tilting the drill rod 9 when the drill rod is put on. This can reduce the labor intensity of the operator to a certain extent and assist the operator in putting the drill rod on. In the invention, the tilting drive member 6.3 that tilts the placement frame 6.2 has various structures, which can be an articulated telescopic cylinder structure or a structure of the present embodiment. Fig.16 The provided lifting screw rod drives the lifting plate to lift the structure of the placing frame 6.2. In this structure, one end of the lifting plate extends to the bottom of the placing frame 6.2, and this end is connected to the bottom of the placing frame 6.2 in a rolling manner.

[0051] In addition, for the drill rod placement assembly 6 of the present invention, its placement frame 6.2 is also used to collect the drill rods 9 that are lowered. In order to facilitate the drill rods 9 to fall into the placement frame 6.2, a driving roller 6.4 is provided on one edge of the frame opening of the placement frame 6.2 in this embodiment. The end of the edge is one end of the hinged placement base 6.1 of the placement frame 6.2. The rotation axis of the driving roller 6.4 is parallel to the width direction of the placement frame 6.2. The rolling form of the driving roller 6.4 can assist the drill rod 9 placed on the edge of the placement frame 6.2 to slide further down. Preferably, a roller motor 6.5 is provided on the placement frame 6.2, and the output shaft of the roller motor 6.5 is connected to the drive roller 6.4 in a transmission manner, and the drill rod 9 is assisted to slide by automatically driving the drive roller 6.4 to rotate. Of course, the present invention can also not provide a roller motor 6.5, and only the drive roller 6.4 is rotatably installed on the placement frame 6.2. The roller motor 6.5 is provided in a manner that a pressure sensor is provided on the rotating shaft of the drive roller 6.4 to sense whether a drill rod 9 is placed on the drive roller 6.4, and when the pressure sensor is sensed, the roller motor 6.5 is prompted to run to drive the drive roller 6.4 to rotate. This method can avoid the real-time operation of the roller motor 6.5 to a certain extent.

[0052] Furthermore, considering the convenience of movement and stability of the device during use, in this embodiment, ground support components 7 are installed at the four corners of the main base 1, as shown in detail. Figure 14-15 . The ground support assembly 7 includes a support wheel 7.2, a ground support lifting member 7.1 and an insertion rod 7.4. The support wheel 7.2 is rotatably connected to the movable end of the ground support lifting member 7.1 through a support connecting rod 7.3. The fixed section of the ground support lifting member 7.1 is installed on the main base 1, and its movable end is transmission-connected to the insertion rod 7.4. The lower end of the insertion rod 7.4 is a pointed end, and the movement direction of the insertion rod 7.4 is opposite to the movement direction of the support wheel 7.2; when the ground support lifting member 7.1 drives the support wheel 7.2 to be located below the bottom of the main base 1, the insertion rod 7.4 is located above the bottom of the main base 1; when the ground support lifting member 7.1 drives the support wheel 7.2 to be located above the bottom of the main base 1, the lower end of the insertion rod 7.4 is located below the bottom of the main base 1. Preferably, the ground support lifting member 7.1 is connected to the insertion rod 7.4 through a rack and pinion transmission assembly 7.5. In this way, the lifting action of the ground-supporting lifting member 7.1 drives the support wheel 7.2 and the insertion rod 7.4 to provide replaceable ground support. The support wheel 7.2 can provide ground support when the device needs to be moved, and the insertion rod 7.4 is inserted into the ground to provide ground support and fixation when the device needs to be fixed for use, thereby ensuring the stability of the main base 1. Of course, in order to ensure the stability of the drill rod placement assembly 6, the ground support assembly 7 can also be installed on the placement base 6.1 of the drill rod placement assembly 6. This arrangement is not shown in the attached drawings of this embodiment. In addition, the ground-supporting lifting member 7.1 can be a telescopic rod assembly or other structural forms, such as other forms listed in the lifting drive structure 4, and no specific restrictions are made to this.

[0053] In addition, considering that when the upper clamping assembly tilts to cause the drill rod 9 to slide down, the support point position of the drill rod 9 causes the direction of the drill rod 9 to not coincide with the central axis of the arc surface of the upper clamping plate 3.3, and the drill rod 9 tilts at a certain angle, causing the drill rod 9 to abut against the upper end of the upper clamping plate 3.3 to form a certain dead angle, and the drill rod 9 is stuck and not easy to slide down. In this embodiment, a push rod is provided at the upper end of each upper clamping plate 3.3, and the push rod is arranged along the radial direction of the arc surface. It is a telescopic structure, and the telescopic end of the push rod faces the central axis of the arc surface. The push rod is extended to push the drill rod 9 not to abut against the upper end of the upper clamping plate 3.3 to avoid the drill rod 9 from getting stuck and not sliding down, thereby improving the stability of the lower rod sliding of the drill rod 9. Further, in order to prevent the push rod from bringing too much friction to the drill rod 9, a cylindrical rolling wheel is installed at the telescopic end of the push rod, and the central axis of the rolling wheel is perpendicular to the telescopic direction of the push rod and the central axis of the arc surface.

[0054] Finally, it should be noted that the present invention also involves control elements such as controllers, which are not specifically limited here.

[0055] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
