Description

Technical Field

[0001] The utility model relates to a cutter, in particular to an electric power pipe cutter for electric power construction. Background Art

[0002] The power pipe is a product that uses PE (modified polyethylene) 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 produce 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. During power construction, when cutting some thinner power pipes, workers usually carry handheld pipe cutters to cut the power pipes. However, in the actual operation process, the handheld pipe cutter is easy to deviate on the power pipe due to improper force of the staff, which easily leads to insufficient precision of the cut, and the use is relatively limited.

[0003] Patent publication number: CN217345693U discloses an electric power pipe cutter for electric power construction, comprising two arc-shaped splints, a fastener is arranged between the two arc-shaped splints, one of the arc-shaped splints is fixedly connected to a connecting plate on its outer wall, a rotating column is rotatably installed through the inner wall of the connecting plate, a splicing block is fixedly connected to the lower end of the rotating column, and a plurality of plug holes are provided on the outer wall of the rotating column around its central annular array, a plug rod is slidably inserted into the interior of one of the plug holes through an elastic member, a positioning ring is fixedly connected to the end of the splicing block, an arc block is slidably arranged on the side wall of the positioning ring, a rectangular shell is fixedly connected to the side wall of the arc block, and a cutting blade is provided on the side of the rectangular shell through an adjustment member for lifting and lowering.

[0004] The above patent provides a solution for easy cutting of electric pipes, but due to the lack of protective components in the design, when the staff operates the cutter to cut the electric pipe, the electric pipe is prone to produce flying chips during cutting. The flying chips may cause certain safety hazards to the staff, the safety is low, and only one cutting port is designed, which also leads to low efficiency in cutting the electric pipe.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] A power pipe cutter for power construction, such as Figure 1-3 As shown, it includes a support frame 1, an outer frame 2 and a bracket 3. The upper end of the support frame 1 is fixedly connected to the outer frame 2. A plurality of slide grooves 211 are arranged at the lower part of the outer frame 2. A horizontal bracket 3 is installed on the front middle part of the outer frame 2. It also includes an inner gear 4, an inner frame 5, a motor 6, a sawtooth 7, a reducer 8 and an outer gear 9. The inner gear 4 is fixedly installed in the middle part of the bracket 3. The inner upper end of the inner side of the outer frame 2 is slidably connected to the inner frame 5. The motor 6 is fixedly installed on the inner side of the inner frame 5. One end of the motor 6 is rotatably connected to the sawtooth 7. The other end of the motor 6 is electrically connected to the reducer 8. The reducer 8 is rotatably connected to the outer gear 9. The outer gear 9 and the inner gear 4 are transmission-connected.

[0022] like Figure 4 As shown, it also includes a catheter 10, a fixing rod 11 and a pressure spring 12. A plurality of catheters 10 are connected to the front side of the lower part of the outer frame 2. Each catheter 10 is connected to the slide groove 211. The fixing rod 11 is slidably installed on the upper end of the catheter 10 through a small hole. A pressure spring 12 is installed between the fixing rod 11 and the catheter 10.

[0023] like Figure 5 As shown, it also includes a cutting frame 13, a baffle 15, a tension spring 14 and a positioning plate 16. The upper end of the support frame 1 is connected to the cutting frame 13 on both sides. A baffle 15 is arranged inside the cutting frame 13. The upper end of the baffle 15 is slidably connected to a sliding opening at the upper end of the cutting frame 13. A tension spring 14 is arranged at the sliding opening at the upper end of the cutting frame 13. The baffle 15 and the cutting frame 13 are connected through the tension spring 14. A plurality of positioning plates 16 are also arranged on the sliding opening at the upper end of the cutting frame 13. It also includes a collecting box 17. A collecting box 17 is slidably arranged at the lower part of the cutting frame 13.

[0024] like Figure 6 As shown, a sliding ball 19 is also included, and a plurality of sliding balls 19 are arranged inside each sliding groove 211 .

[0025] When using the electric power pipe cutter for electric power construction, according to the actual length of the electric power pipe that needs to be cut, the user first pulls the baffle 15, and the baffle 15 overcomes the elastic force of the tension spring 14 and moves, and at the same time, the positioning plate 16 slides onto the sliding mouth. After being blocked by the positioning plate 16, the baffle 15 is positioned to a suitable cutting position, and the user then pulls up the fixing rod 11 on the conduit 10, and the fixing rod 11 overcomes the elastic force of the pressure spring 12 and is pulled up. At the same time, multiple electric power pipes that need to be cut are placed in the conduit 10 in turn, and the electric power pipe is pushed by hand to move. After entering the conduit 10, the electric power pipe moves into the slide groove 211. When the electric power pipe contacts the sliding ball 19 in the slide groove 211, the sliding friction between the electric power pipe and the slide groove 211 changes to rolling friction, which can reduce the resistance of the user to push the electric power pipe. When one end of the pushed electric power pipe moves to the position of the baffle 15, the electric power pipe reaches a suitable cutting position under the blockage of the baffle 15. Position, then release the fixing rod 11, the fixing rod 11 is pressed down due to the elastic force, and the power pipe is stably fixed. The user starts the motor 6. When the motor 6 works, the saw teeth 7 rotate at high speed. At the same time, the motor 6 also drives the reducer 8 to work, and the reducer 8 drives the outer gear 9 to rotate at a low speed. Since the inner gear 4 is fixed, the outer gear 9 rotates around the inner gear 4 under the transmission action, and at the same time drives the reducer 8, the motor 6, the saw teeth 7 and the inner frame 5 to start rotating. The inner frame 5 rotates on the slideway on the inner side of the outer frame 2, so that the saw teeth 7 are transferred into the cutting frame 13 to stably cut the power pipe. Since the entire cutting is carried out in the relatively closed cutting frame 13, the flying chips generated after the power pipe is cut will not splash out, thereby improving the safety during cutting. At the same time, the cut power pipe will fall into the collection box 17 for collection. After the power pipes are all cut, the collection box 17 is pulled out to take out the cut power pipes for use.

[0026] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
