Background
A contact line parallel to the track is arranged above the electrified railway track, and electric energy on the contact network is transmitted to an electric locomotive or a motor train unit through sliding contact between the contact line and a pantograph of the locomotive. In order to ensure the current-receiving quality, the contact line is required to be flat and equal in height, so that the pantograph and the contact line can be smooth in high-speed sliding contact, and jump, offline and the like cannot be generated. For this purpose, a plurality of integral hanger devices are installed between the contact wire and the carrier cable for suspending the contact wire.
The existing integral hanger device is an assembly formed by crimping a plurality of parts, and the parts are produced by a stamping process. The whole dropper device is fixed with the contact wire and the carrier cable into a whole through the contact wire dropper clamp and the carrier cable dropper clamp respectively during installation, namely the contact wire dropper clamp clamps the contact wire through fastening the bolt of the contact wire dropper clamp, and the carrier cable dropper clamp clamps the carrier cable through fastening the bolt of the carrier cable dropper clamp.

Because the contact net has elasticity, the contact net can vibrate under the action of the pantograph in motion, and especially when the high-speed rail operates, the vibration of the contact net is more severe. Operation practice shows that the integral hanger device with the structure has certain potential safety hazard in use. The number of parts in the integral hanger device is large, more movable parts exist in the interconnection of the parts, the movable parts are easy to wear in vibration, for example, the positions of the hanging rings, which are contacted with the heart-shaped guard rings, are easy to wear, the wall thickness of the heart-shaped guard rings is only 1.5mm, the strength margin is not large, the wear is serious over time, and the breakage is easy to occur; the hanging string at the outlet of the crimping pipe is easy to break because of repeated bending; the bolt is easy to loose, and if the nut is not found in time, the nut is easy to fall off. The problems can cause bow net faults, particularly high-speed rails, the running speed is high, and the fault consequences of the whole dropper device are more serious. In order to prevent such faults, a great amount of manpower and material resources are invested in operation to monitor and check the operation states of key stressed parts including the integral hanger device and the like, and the operation cost is increased.

The invention relates to a screwless integral dropper device, which comprises a screwless contact wire dropper clamp 100, a screwless carrier cable dropper clamp 200 and a dropper 300, wherein a ball head 331 of a lower double-hole crimping pipe 33 extends into an integral hollow cylinder 13 of the screwless contact wire dropper clamp 100 and is rotationally connected with the screwless contact wire dropper clamp, a ball head 321 of an upper double-hole crimping pipe 32 extends into an integral hollow cylinder 23 of the screwless carrier cable dropper clamp 200 and is rotationally connected with the screwless contact wire dropper clamp, the ball heads of the upper double-hole crimping pipe and the lower double-hole crimping pipe can rotate randomly in the integral hollow cylinder, the connection mode can ensure that the dropper 300 is not bent when the contact wire 700 or the carrier cable 600 is deflected, the connection position of a dropper wire body 31 and the upper double-hole crimping pipe is not easy to break, the service life of the integral dropper device is prolonged, the operation cost is low, fatigue damage caused by repeated bending of the dropper wire at a transition position due to rigid connection in a rigid vibration mode is greatly avoided, and even breakage of the dropper is greatly avoided; when the device is installed, the bolt-free contact wire hanging string clamp can clamp the contact wire and the bolt-free carrier cable hanging string clamp can clamp the carrier cable without installing bolts, and the construction is rapid and convenient. The clamping principle is as follows: the locating pin and the locating slot are respectively provided with a corresponding inclined plane, the inclined planes are equal, when an external force (clamping force) is applied to enable the two half-string clamps to be inserted into each other, the inclined planes of the locating pin move along the inclined planes of the locating slot, the clamping force along the inclined planes can be decomposed into a horizontal component force and a vertical component force, the horizontal component force enables the two half-string clamps to be inserted into each other, the vertical component force enables the two half-string clamps to be close to each other until contact surfaces of the two half-string clamps are in contact with each other, and finally the contact line or the carrier cable is clamped.
2. In the bolt-free integral string hanging device, the bolt-free contact line string hanging wire clamp and the bolt-free carrier cable string hanging wire clamp are respectively provided with a locking device formed by meshing an upper straight rack plate and a lower straight rack plate and a threaded through hole for disassembly, and the locking device can enable the two half string hanging wire clamps after clamping to be kept in a locking state without external force pushing the wire clamps to be unable to be loosened; the upper straight rack plate and the lower straight rack plate are respectively arranged at two ends of the hanging string wire clamp, so that double anti-loosening can be formed, anti-loosening force is uniformly distributed on the wire clamp, and anti-loosening reliability is improved. The two locked half-string clamps can be separated by matching the threaded through holes with bolts for disassembly, and can be reused after separation. When the wire clamp is not required to be disassembled, the plastic round head for the threaded through hole is plugged, when the wire clamp is required to be disassembled, the plastic round head is pulled out, the matched bolt is screwed in the threaded through hole for disassembly, after the threaded through hole for disassembly is screwed in by the bolt, the end part of the bolt is propped against the left end face or the right end face of the positioning pin, and along with the continuous screwing in of the bolt, the two half-string clamps are subjected to a pair of forces with equal size and opposite directions, so that the two half-string clamps are gradually separated.
3. The wire clamp of the wire hanger without the bolt contact wire and the wire clamp of the wire hanger without the bolt bearing wire are designed into a symmetrical structure, and a set of dies is adopted in production, so that the processing cost can be reduced, and the produced wire clamp is good in consistency, so that the stress of the wire clamp is more reasonable, and the work is more reliable.
4. The whole dropper device without the bolts has current passing through and is a carrier fluid. Under normal working conditions, the whole dropper device is in a tension state, and the contact area between the ball head of the ball-type pressure joint pipe and the inner wall of the whole hollow cylinder is much larger than the cross section area of the dropper line body, so that the ball-type pressure joint pipe is in good contact. However, because the ball head is in sliding or rolling contact with the inner wall of the integral hollow cylinder, the ball head is not fixedly connected, and poor contact is possible, and in order to ensure that current can smoothly pass through the connecting part, an upper short connecting line and a lower short connecting line are arranged in the integral hanger device. When the cable is installed, the lower end of the upper short connecting wire is integrally connected with the string through crimping through the upper double-hole crimping pipe, the upper end of the upper short connecting wire penetrates through the first threading round hole or the second threading round hole and penetrates out of the first threading round hole or the first threading round hole, after the left half string clamp of the carrier cable and the right half string clamp of the carrier cable are mutually inserted, the first threading round hole is communicated with the second threading round hole and is different from the first threading round hole, the middle part of the clamping positioning device extrudes the upper short connecting wire into an ellipse, so that the upper short connecting wire is compacted, crimping electric contact like a bolt type electric connecting wire clamp is formed, a perfect conductive channel is formed between the string and the carrier cable string clamp, and the conductive reliability of a connecting part is improved; likewise, the upper end of the lower short connecting wire is integrally connected with the hanging string in a crimping way through the lower double-hole crimping pipe, the lower end of the lower short connecting wire penetrates through the first threading round hole or the second threading round hole and penetrates out of the second threading round hole or the first threading round hole, after the left half hanging string clamp of the contact wire and the right half hanging string clamp of the contact wire are mutually inserted, the first threading round hole is communicated with the second threading round hole and are different from each other, the middle part of the positioning and clamping device extrudes the lower short connecting wire into an ellipse, so that the lower short connecting wire is compacted, crimping type electric contact like a bolt type electric connecting wire clamp is formed, a perfect conductive channel is formed between the hanging string and the contact wire hanging string clamp, and the conductive reliability of the connecting part is improved.
