DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present utility model, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0027] See also Figure 1-4The circumferential drilling device for the pipe wall shown in the figure includes a lifting platform 3, a support frame 1 installed on the lifting platform 3, and a center positioning tube 2 which is laterally inserted and fixed in the support frame 1. A plurality of drills 5 are circumferentially arranged at the end of the center positioning tube 2. The drill bit 54 of the drill rig 5 extends into the center positioning tube 2 along the radial direction of the center positioning tube 2. The center positioning tube 2 is circumferentially arranged with a through hole 25 through which the drill bit 54 can pass. A driving mechanism 4 for driving the center positioning tube 2 to rotate on the support frame 1 is installed on the lifting platform 3 and located on the side of the support frame 1.

[0028] Through the implementation of the above technical solution, when in use, the pipe to be drilled is clamped by a manipulator or other clamping device, and the end of the pipe is coaxially inserted into the end of the center positioning tube 2 with the drill 5, and then the first drilling is performed on the pipe wall by multiple drills 5 at the same time. After the first drilling is completed, the center positioning tube 2 is driven by the driving mechanism 4 to rotate a specified angle, and then the second drilling is performed on the pipe wall by multiple drills 5 at the same time, and so on until all the holes on the first level are drilled, the driving mechanism 4 reversely drives the center positioning tube 2 back to the original position, and then the pipe is continued to be inserted into the center positioning tube 2 by a manipulator or other clamping device, and the second level of the pipe is continued to be drilled, and so on, until all the holes on the required level are drilled. The circumferential drilling device for the pipe wall can simultaneously drill holes in the circumference of the pipe wall, thereby improving the efficiency of the circumferential drilling of the pipe wall. For example, in one embodiment, three drilling rigs 5 are arranged at equal intervals, and 12 holes need to be drilled in the pipeline layer. According to the traditional method, 12 times of drilling are required. Assuming that each drilling takes 1 minute, it takes 12 minutes. However, using the present pipeline wall circumferential drilling device, only 4 holes need to be drilled at the same time. Since 3 holes can be drilled at the same time each time, it only takes 4 minutes to drill 12 holes.

[0029] In this embodiment, in order to further provide a driving mechanism 4, the driving mechanism 4 includes a gear sleeve 44 fixedly sleeved on the center positioning tube 2, a motor 42 mounted on the lifting platform 3 through a motor frame 41, and a gear 43 sleeved on the output shaft of the motor 42 and meshing with the gear sleeve 44. The motor 42 rotates to drive the gear sleeve 44 to rotate, thereby driving the center positioning tube 2 to rotate, so that the drilling position of the drilling rig 5 in the circumferential direction can be switched. In order to accurately switch the drilling position, the motor 42 can use an angle motor 42. The motor 42 does not rotate circumferentially, but reciprocates within a certain angle range.

The center positioning tube 2 is stably supported by the plurality of support seats 11, and the center positioning tube 2 can rotate under the drive of the driving mechanism 4 by the arrangement of the bearing 12.

[0031] In this embodiment, in order to further provide a center positioning tube 2, the center positioning tube 2 includes a straight tube 21 rotatably arranged on the support frame 1, and a trumpet tube 22 and a circular tube 24 sequentially connected to the straight tube 21, and the drill 5 is installed on the circular tube 24. Through the arrangement of the trumpet tube 22 and the circular tube 24, the inner diameter of the position where the drill 5 is installed is larger than that of the straight tube 21, which increases the visible space, facilitates the insertion of the drill bit 54, and facilitates the installation and replacement of the drill bit 54.

[0032] In this embodiment, a plurality of mounting seats 23 are arranged on the outer wall of the annular tube 24, the outer ends of the mounting seats 23 are arranged as a plane, the through holes 25 are arranged through the mounting seats 23, and the drilling rig 5 is installed on the plane. Through such an arrangement, the drilling rig 5 is installed on the plane, which improves the stability of the installation.

The feeding and extraction of the drilling machine body 51 during drilling is realized by the action of the cylinder 53.

[0034] In this embodiment, in order to further provide a lifting platform 3, the lifting platform 3 includes an upper platform 33, a lower platform 31, and a cylinder 34 arranged in the center of the upper platform 33 and the lower platform 31, and support columns 35 are arranged at the four corners of the lower platform 31. The upper platform 33 can be driven by the cylinder 34 to drive the upper equipment to adjust the height to adapt to different working conditions.

[0035] In this embodiment, the center of the support column 35 is set as a hollow hole, and the upper platform 33 is provided with a plurality of guide rods 32 that penetrate the upper platform 33 and slide to extend to the hollow hole. When the oil cylinder 34 is working, the guide rods 32 can guide and slide in the hollow hole to increase the vertical movement stability of the upper platform 33.

[0036] In this embodiment, the bottom side of the support column is provided with a plurality of air inlet and outlet notches connected to the hollow hole. The air inlet and outlet notches are provided to break the seal when the guide rod 32 is extended and retracted, and the movement of the guide rod 32 in the hollow hole will not be affected by air pressure.

[0037] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments.
