Description

Technical Field

[0001] The utility model relates to the technical field of power distribution network, in particular to a power distribution network laying device capable of cutting electric wires. Background Art

[0002] In the field of power grid distribution engineering, line laying is an extremely basic and critical link. Its quality and efficiency directly affect the progress of the entire power grid construction and maintenance work. With the continuous expansion of the scale of modern power grids and the increasing technical requirements, traditional line laying devices have gradually exposed many limitations.

[0003] In power distribution network projects, it is often necessary to cut wires according to line planning and construction requirements to obtain wire segments of appropriate lengths. However, traditional wire-laying devices lack effective cutting functions, and construction workers often need to use additional cutting tools to operate. This not only increases the workload of construction workers, but also makes it difficult to ensure cutting accuracy and stability using a single cutting tool in the complex environment of the construction site.

[0004] Therefore, how to provide a power distribution network laying device that can cut electric wires is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] One purpose of the present invention is to provide a power distribution network pay-out device that can cut electric wires. The present invention can quickly and conveniently complete the cutting work after pay-out. The blade can be retracted after cutting to prevent scratching the cable, and the splint can be used to clamp the cable during cutting to ensure stable and reliable cutting.

[0006] According to an embodiment of the present invention, a power distribution network pay-out device capable of cutting electric wires comprises a base, a bracket and a movable seat;

[0007] The top of the base is symmetrically fixed with brackets welded together, and a pay-off wheel is rotatably installed on the upper inner side of the bracket. Supports are fixedly welded at both ends of the front side of the top of the base, and support rods are fixedly welded on the upper and lower sides of the inner walls of the two groups of supports. A movable seat is slidably sleeved on the support rod, and a pay-off seat is fixedly installed on the top of the movable seat. A knife seat is fixedly installed on the upper front end of the inner wall of the pay-off seat, and a storage groove is provided at the bottom of the knife seat. A first electric push rod is fixedly installed in the center of the top of the knife seat, and a blade is fixedly installed on the bottom of the first electric push rod. Second electric push rods are symmetrically fixedly installed on the front ends of both sides of the pay-off seat, and a splint is fixedly installed on the inner end of the second electric push rod.

[0008] Furthermore, a cutting seat is fixedly installed on the inner side of the wire-paying seat and below the knife seat, and a cutting groove is horizontally opened on the top of the cutting seat.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0024] refer to Figure 1-2 , a power distribution network laying device capable of cutting electric wires, comprising a base 1, a bracket 2 and a movable seat 8;

[0025] The top of the base 1 is symmetrically fixed with brackets 2 on both sides, and a pay-off wheel 3 is rotatably installed on the upper inner side of the bracket 2;

[0026] Among them, a driving motor 4 is fixedly installed on the outer wall of one side of the bracket 2, and the output shaft of the driving motor 4 is transmission-connected to the pay-off wheel 3;

[0027] Secondly, a Hall sensor 11 is fixedly mounted on the outer wall of the other side of the bracket 2, and the Hall sensor 11 is connected to the rotating shaft of the pay-off wheel 3;

[0028] In addition, the four corners of the bottom of the base 1 are rotatably mounted with moving wheels 5 to facilitate the flexible movement of the device;

[0029] In this embodiment, the drive motor 4 provides power for the rotation of the pay-out wheel 3, so that the pay-out wheel 3 can perform the pay-out operation as needed. By controlling the speed and direction of the drive motor 4, the speed and direction of the pay-out can be accurately controlled. The Hall sensor 11 can monitor the number of rotations and angle information of the pay-out wheel 3 in real time, and then calculate the length of the pay-out based on parameters such as the circumference of the pay-out wheel 3, which is convenient for the staff to accurately measure and monitor the pay-out operation.

[0030] refer to Figure 1-4 , the two ends of the top front side of the base 1 are fixedly welded with supports 6, and the upper and lower sides of the inner walls of the two groups of supports 6 are fixedly welded with support rods 7, a movable seat 8 is slidably sleeved on the support rod 7, and a wire-paying seat 9 is fixedly installed on the top of the movable seat 8. A knife seat 13 is fixedly installed on the upper front end of the inner wall of the wire-paying seat 9, and a storage groove 19 is provided at the bottom of the knife seat 13. A first electric push rod 14 is fixedly installed in the center of the top of the knife seat 13, and a blade 20 is fixedly installed at the bottom of the first electric push rod 14. Second electric push rods 17 are symmetrically fixedly installed on the front ends of both sides of the wire-paying seat 9, and a splint 18 is fixedly installed on the inner end of the second electric push rod 17.

[0031] Among them, a cutting seat 15 is fixedly installed inside the pay-off seat 9 and below the knife seat 13, and a cutting groove 16 is horizontally opened on the top of the cutting seat 15; the blade 20 is stored in the storage groove 19, and the blade 20 faces downward;

[0032] Secondly, a power supply box 10 is fixedly mounted on the front wall of the movable seat 8, and a battery is installed in the power supply box 10;

[0033] In addition, guide wheels 12 are movably installed on the upper and lower sides of the pay-off seat 9, and the outer walls of the two sets of guide wheels 12 are provided with wheel grooves;

[0034] In this embodiment, the cable can be located between the two sets of guide wheels 12 for line payout, and during the line payout process, the movable seat 9 can move left and right on the support rod 7 along the movement trajectory of the cable when it is paid out. When the line payout is completed and cutting is required, the second electric push rod 17 can be started first. At this time, the two sets of clamps 18 can clamp the cable. After clamping, the first electric push rod 14 is started to push the blade 20 downward to cut the cable.

[0035] Working principle: During the wire-paying operation, first place the wire roll on the wire-paying wheel 3, and drive the wire-paying wheel 3 to rotate by the driving motor 4 to realize the wire-paying. The Hall sensor 11 monitors the rotation of the wire-paying wheel 3 in real time and transmits the data to the control system so that the staff can grasp the wire-paying length. When the wire passes through the wire-paying seat 9, the guide wheel 12 guides and supports it to ensure smooth transportation. If the wire needs to be cut, the second electric push rod 17 pushes the splint 18 to clamp the wire, and then the first electric push rod 14 pushes the blade 20 to extend from the storage slot 19. The blade 20 cuts the wire at the cutting slot 16 of the cutting seat 15. After the cutting operation is completed, the blade 20 is retracted into the storage slot 19, and the splint 18 releases the wire. The movable seat 8 can slide and adjust its position on the support rod 7 according to the movement trajectory of the cable during wire-paying. At the same time, during the entire operation process, the power box 10 supplies power to the first electric push rod 14 and the second electric push rod 17 to ensure the normal operation of the device, and the device can be conveniently moved to different work locations through the movable wheel 5, thereby improving the flexibility and convenience of the operation.
