Description

Technical Field

[0001] The utility model relates to the technical field of electric power pipes, in particular to a drilling device for processing electric power pipes. Background Art

[0002] The power pipe is a product that uses PE for hot-dip plastic or epoxy resin for internal and external coating, and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and will not cause electrical corrosion. It has low water absorption, high mechanical strength, and low friction coefficient, and can achieve the purpose of long-term use. It can also effectively prevent the damage of plant roots and soil environmental stress. When processing the power pipe, it is necessary to drill holes on the surface of the power pipe, and for this purpose, a drilling device is required.

[0003] A Chinese patent with the announcement number CN107901126A discloses a drilling device for pipe processing, which includes a box body, a motor is fixedly connected to the right side of the back side of the inner wall of the box body, a disc is fixedly connected to the output end of the motor, a transmission rod is fixedly connected to the right side of the front side of the disc, a transmission frame is slidably connected to the surface of the transmission rod, a first polished rod is fixedly connected to the top and bottom of the left side of the transmission frame, and a first slip ring is slidably connected to the surface of the first polished rod. The present invention solves the problem of cumbersome operation of the existing drilling device when fixing pipes by setting a box body, a motor, a disc, a transmission rod, a transmission frame, a first polished rod, a first slip ring, a horizontal plate, a vertical plate, a movable rod, a second polished rod, a second slip ring, a transmission plate, an inclined hole, a vertical rod and a clamping plate. The drilling device for pipe processing has the advantage of being easy to fix pipes, reduces the labor intensity of workers, and improves the practicality of the drilling device.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff uses a clamping plate to press the pipe, and then uses the drilling device body to drill holes on the surface of the pipe. However, the outer surface of the pipe is an arc surface. When the drill bit contacts the pipe, there is a possibility that the end of the drill bit will be deflected. To avoid this situation, two methods are usually used to solve it. One is to process a plane at the drilling position in advance, and the other is to first use the center drill point to drill a small hole groove at the drilling position, and then change the drill bit to drill a hole at the small hole groove position. The former requires the use of other processing equipment to process the plane in advance so that the drill bit can drill smoothly in a flat environment, which increases the plane processing steps. The latter requires the replacement of different tools to locate the drilling position for the drill bit, which increases the tool replacement steps. Both of the above methods require additional processing steps to ensure that the drill bit can drill holes in the pipe smoothly, which increases the processing steps of the pipe, prolongs the processing time of the pipe, and reduces the processing efficiency of the pipe.
