Description

Technical Field

[0001] The utility model relates to the technical field of power pipe cutting equipment, and specifically discloses a power pipe cutting device for power construction. Background Art

[0002] Power pipe is a kind of pipe used to protect cables. It has excellent corrosion resistance, electrical insulation, low water absorption and high mechanical strength. It is usually coated inside and outside with modified polyethylene or epoxy resin. Power pipe is mostly used in urban power grid construction and transformation, urban municipal transformation projects, civil aviation airport engineering construction, engineering park and community engineering construction, as well as transportation and road and bridge engineering construction. During the use of power pipe, power pipe cutting device is required to cut the power pipe into different lengths to meet the corresponding installation requirements.

[0003] A Chinese patent with patent number CN221436602U discloses an electric power pipe cutting device for power construction, including two mounting rods, the lower ends of the two mounting rods are fixedly connected to two support rods, the lower ends of the four support rods are fixedly connected to base feet, the front ends of the upper ends of the two mounting rods are fixedly connected to load-bearing rods, the front ends of the two load-bearing rods are commonly fixedly connected to a load-bearing plate, the lower ends of the load-bearing plates are fixedly connected to a cutting mechanism, and two fixing components are commonly fixedly connected between the two mounting rods. The utility model discloses an electric power pipe cutting device for electric power construction, which provides a fixing component, and rotates the corresponding fastening plates downward by two knobs, and at the same time the corresponding springs are deformed until the two fastening plates are in contact with the electric pipe and tightly press against the electric pipe, thereby achieving clamping and fixing of the electric pipe. There is no need to manually press and fix the electric pipe, which saves manpower and is simple and convenient. However, the position adjustment and fixation of the above-mentioned cutting device are inconvenient, resulting in workers having to spend effort or use additional carrying equipment to carry it when the position of the device needs to be adjusted, which is relatively inconvenient. When the length of the electric pipe cut by the above-mentioned cutting device is much longer than the length of the entire cutting device, in order to keep the electric pipe stable during the cutting process, workers are still required to hold the electric pipe from both ends, which affects the scope of application of the above-mentioned cutting device to a certain extent. In addition, the mounting rod, fixing rod, fixing ring and other components in the above-mentioned cutting device cannot be disassembled and placed separately when idle, which is not conducive to saving the space occupied by the above-mentioned cutting device during the idle process. Therefore, in order to solve the above-mentioned problems, the utility model proposes an electric power pipe cutting device for electric power construction. Utility Model Content

The use of the identification plate above the first connecting plate makes it convenient for workers to distinguish between the first connecting plate and the second connecting plate.

[0016] 2. The use of two second brackets and four second connecting plates in the auxiliary support structure can connect the second bracket to the first bracket through the second connecting plate before use to limit the position of the two second brackets. The design of multiple second sockets inside the second connecting plate can adjust the distance between the second bracket and the first bracket by adjusting the sockets into which the second rod and the third rod are inserted, so that the arc groove and the third cushion can meet the support requirements of power pipes of different cutting lengths, thereby improving the applicability of the device.

[0034] The electric power pipe cutting device disclosed in this embodiment is to place the two first connecting plates 16 in the support and limiting mechanism 1 above the two first brackets 11 respectively before use, and adjust the spacing between the two first brackets 11 and the insertion hole of the first plug rod 111 according to the length of the electric power pipe to be cut. After the adjustment is completed, take out the nut 17 from the tool box 18 and screw it to the outside of the first plug rod 111 to fix the first connecting plate 16 to the first bracket 11. The support mechanism below is assembled, and then the second brackets 31 in the two auxiliary support structures 3 are respectively placed at both ends of the support and limiting mechanism 1, and the four second connecting plates 32 are respectively pressed. Place two of them in a group on both sides of the first bracket 11 and the second bracket 31. Similarly, adjust the distance between the second bracket 31 and the first bracket 11 according to the length of the power pipe to be cut, and insert the second plug rod 112 and the third plug rod 313 on the same side and the same end into the corresponding second plug holes 321 in the same second connecting plate 32 respectively.

Then install the remaining three second connecting plates 32 according to the same operation, so that the two second connecting plates 32 on the same side are staggered in height. After the installation is completed, the cutting device is assembled.

[0035] Release the brakes of the first universal wheel 12 and the second universal wheel 34, move the cutting device to a suitable position, and then step on the brake of the brake wheel to fix the cutting device.

During the clamping and fixing process, the second soft pad 141 undergoes reversible deformation to better fit the outer surface of the power pipe. After the fixing is completed, the terminal device is used to start the motor 22 to drive the cutter 21 to rotate. During the rotation process, the terminal device is used to simultaneously control the two telescopic rods 24 to retract, so that the cutter 21 moves in the direction of the power pipe to cut the power pipe. Until the cutting is completed, the telescopic rod 24 is controlled to extend to push the cutter 21 above the power pipe, and the threaded rod 15 is rotated in the opposite direction to release the second soft pad 141 and the arc-shaped pressure plate 14 from fixing the power pipe.
