Description
Technical Field
The invention relates to the field of overhead line system dropper machining, in particular to a double-head dropper assembling method.
Background
Along with the high-speed development of the high-speed railway technology in China, the method has higher requirements for the quality and the standard of railway processes. In electrified railway lines, the contact net is an important component for ensuring the normal operation of the railway. The contact net is lapped on the electrified railway power supply line to supply power to the electric locomotive and the accessory equipment thereof. In a contact net system, a hanger is used as one of key factors of good contact between a contact net and a locomotive pantograph, and a set of integral hanger is required to be installed on a line every 6-8 meters to suspend a contact line on a carrier cable, so that the suspension height of the contact line is ensured, and the contact line is kept to be elastic to ensure that the contact net and the locomotive pantograph have good contact relation. The dropper comprises a dropper wire, a heart-shaped ring and a clamping tube which are arranged on one side or two sides of the dropper wire, and a wire nose which is arranged on one end part or two end parts of the dropper wire. The production process of the dropper mainly comprises the steps of wire feeding and cutting, threading, tensioning, crimping, marking and bundling, wherein the threading comprises the step that the dropper passes through a clamping tube, a heart-shaped ring and a wire nose, the tensioning refers to the step that the heart-shaped ring and the clamping tube are tensioned by the dropper, and the crimping comprises the clamping tube and the pressing of the wire nose and the dropper. The production mode of the existing dropper is mainly manual, and generally adopts four to five people as one class to carry out the working procedures of the steps. The production mode has the problems of high labor cost, low precision of finished products of the hanging strings and the like, particularly has the problems of inconsistent and uneven length and size, and cracking of a clamping pipe and/or a wire nose caused by unstable compression joint or overlarge compression joint force in the manual production mode. In the process of crimping the crimping tube and the string, pre-pressing is needed, namely, the crimping tube is clamped and fixed, then the string is tightened, namely, the two ends of the string are pulled to enable the heart-shaped ring to be tightly abutted with the crimping tube, and finally, the crimping tube is pressed, namely, the crimping tube is extruded to enable the string to be tightly and fixedly connected with the crimping tube. In the existing crimping process, manual stepping operation is mainly adopted, so that on one hand, the operation efficiency is low, on the other hand, the requirement of mechanical automatic production cannot be met, and more importantly, the tight butt joint between the heart-shaped ring and the crimping pipe is loose due to insufficient tightening degree, and the crimping pipe is cracked due to loosening or overlarge tightening degree between the hanging string and the crimping pipe.
In view of the above, the present invention is intended to provide a double-headed dropper assembling method, in which an assembly platform and components thereon, particularly a crimping tool part, a crimping press part, etc. for crimping are provided to enable automation in the dropper assembling process, thereby improving production efficiency and yield.

In this embodiment, when the string is pulled to tightly contact the heart-shaped ring a and the string b, the clamping rod 738 is in a raised state, when the crimping operation of the string b and the string is completed, the clamping rod 738 is in a lowered state to avoid the interference to the subsequent string production operation, when the clamping rod 738 is in the raised state, the clamping rod 738 protrudes from the clamping rod supporting table 739 to clamp the heart-shaped ring a, and when the clamping rod 738 is in the lowered state, the upper end surface of the clamping rod 738 does not exceed the upper surface of the clamping rod supporting table 739.
In this embodiment, the clamping fixture mounting plate 733 is required to be capable of sliding relative to the clamping sliding plate 72 because the heart-shaped ring a on the clamping fixture supporting table 739 moves toward the clamping tube b on the clamping portion 74 when both ends of the string are pulled, so that the clamping fixture portion 73 moves toward the clamping portion 74 and abuts against the clamping portion 74, and the clamping fixture portion 73 is capable of sliding relative to the clamping sliding plate 72 to provide a space and a guide rail for the movement of the clamping fixture portion 73, thereby avoiding damage to the clamping fixture portion 73 when the string is pulled.
