Problems solved by technology
Because it involves high-altitude operations, it is often necessary to take a ladder for operations, which is inefficient and has potential safety hazards. An automated device is needed to complete the assembly between the clamp and the contact wire
Since the contact wire clamp on the suspension string needs to be oriented and installed through the longitudinal groove on the contact wire, the precise assembly requirements for the positioning and locking of the contact wire and the clip clamping into the longitudinal groove have created high design difficulties

Embodiment Construction
[0026] The present invention is used to connect the ends of the suspension strings 3 to the contact wires 7 . The end of the suspension string 3 is bent into an annular bend 8, and the annular bend 8 is connected to the wire clamp 6 through the suspension ring 9. The wire clamp 6 is U-shaped, and its notch should correspond to the longitudinal groove 701 on the contact wire 7 for snap-fit assembly . The wire clip 6 is also provided with a fastening bolt 10 and a corresponding fastening nut 11. On the one hand, the fastening bolt 10 and the fastening nut 11 fix the base of the lifting ring 9 on the wire clip 6, and on the other hand, the wire clip 6 is notched. After being snapped into the longitudinal groove 701 , the opening of the notch of the wire clip 6 can be limited by screwing in the tightening nut 11 , so as to ensure a tight snap fit between the notch and the longitudinal groove 701 and avoid loosening.

A positioning and mounting device of a contact wire clamp for mounting a catenary dropper comprises a multi-degree-of-freedom mechanical arm and a platform, and a positioning system, a locking system and a clamping system are arranged on the platform; the positioning system is used for positioning the relative position of the free end of the multi-degree-of-freedom mechanical arm and the contact line according to a longitudinal groove in the contact line, and the locking system is used for locking the relative position of the free end of the multi-degree-of-freedom mechanical arm and the contact line after positioning of the positioning system. The clamping system is provided with a positioning seat and a driving mechanism, the positioning seat is provided with a positioning assembly for positioning and fixing the end part of the dropper, and the driving mechanism is used for pushing the positioning seat towards the direction of the contact line locked by the locking system, so that a wire clamp at the end part of the dropper fixed by the positioning assembly is clamped and fixed on a longitudinal groove in the contact line. The device is used for quickly, efficiently and safely assembling the dropper to the contact line segment.
Description
technical field [0001] The invention relates to the technical field of catenary hanging string installation, in particular to a positioning and installation device for a contact wire clip for catenary hanging string installation. Background technique [0002] In the installation and construction of the hanging string, the two ends of the hanging string are respectively bent to form annular bends. The annular bends are connected to the hanging ring and the wire clip in turn, and then the wire clip is installed with the contact wire and the bearing cable respectively. The hanging ring is tightened by tightening The bolts and fastening nuts are fitted on the corresponding wire clips. [0003] In the assembly of the hanging string corresponding to the contact wire end, the notch of the wire clip is usually pushed to the contact wire manually, so that the notch ends on both sides of the wire clip are clamped into the longitudinal grooves on the contact wire to complete the instal...
