Description

Technical Field

[0001] This invention relates to the field of crimping technology, specifically to a crimping device and system for power grid transmission lines. Background Technology

[0002] A wire crimping tube is used to connect two power lines. It is generally an aluminum round tube with a certain degree of ductility. The user inserts the ends of the two power lines into the crimping tube, so that the ends of the two power lines abut against each other. Then, the crimping tube is crimped to form a shape, and finally the two power lines are connected.

[0003] When using a traditional crimper, the user needs to control one power line with one hand and another wire with the other. The lack of a free hand to operate the crimper makes the entire crimping process complicated. Moreover, controlling the wire by hand is unstable, resulting in poor crimping effect. In addition, there is an oxide film on the surface of the crimped pipe. The oxide film has high resistance characteristics, and traditional crimpers cannot remove the oxide film. The power transmission effect of the crimped connection is poor. If the oxide film is removed manually, it will increase the workload. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a power grid transmission line crimping device and system, which solves the following problems: When using traditional crimpers, the user needs one hand to control one power line and the other hand to control another conductor, leaving no free hand to operate the crimper, making the entire crimping process complex. Furthermore, manual control of the conductors is unstable, resulting in poor crimping performance. Additionally, the surface of the crimped connector may have an oxide film with high resistance, which traditional crimpers cannot remove, leading to poor power transmission in the crimped connection. Manual removal of the oxide film further increases the workload.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0010] In another aspect, the application also provides a power network transmission line detection system for detecting the power network transmission line crimping device.

[0011] The application has the following beneficial effects:

[0012] (1) When the connecting block drives the lower die to move downward for crimping, the connecting block drives the guide rod to push the charging chamber to move away from the lower die, after the crimping is completed, the connecting block drives the lower die to move upward, at this time, the charging chamber is not pushed by the guide rod, and under the driving of the supporting unit, the charging chamber moves to the direction close to the lower die to reset, finally, the lower outlet of the charging chamber is located above the lower die, and the lowermost crimping pipe in the charging chamber will roll onto the lower die to complete the blanking step.

[0013] (2) When the charging chamber moves left and right, the lowermost crimping pipe in the charging chamber will always roll on the grinding block, and when the crimping pipe rolls on the grinding block, the oxide film on the surface of the crimping pipe can be removed, the oxide film has high resistance and affects the power transmission efficiency.

[0014] (3) When the connecting block moves up and down in the longitudinal direction, the charging chamber and the gear are driven to move left and right in the transverse direction, and the compression spring on the back of the rack can always support the rack to tightly adhere to the gear, so that the engagement is always maintained.
