Description

Wire clamp for railway contact net Technical Field The utility model relates to the technical field of railway contact networks, in particular to a wire clamp for a railway contact network. Background The railway contact net is a core power supply system of an electrified railway, is erected along the overhead of a railway line, and transmits electric energy to a train through contact of a pantograph and an electric locomotive, and has a complex structure and various functions. The utility model provides a wire clamp for a railway contact network, which comprises a clamping plate and a locking piece, wherein the wire clamp is searched and has the bulletin number of CN 221497726U. The clamping plates are provided with two clamping plates, the two clamping plates can be combined, a connecting part for connecting a positioning pin can be formed at the top end after the two clamping plates are combined, and a clamping channel for allowing a contact wire to pass through and limiting and clamping the contact wire can be formed at the bottom end after the two clamping plates are combined. The locking piece is provided with at least two, and the locking piece can lock the two splints which are matched. The wire clamp for the railway contact net is provided with the two clamping plates with the same structure, has a simple structure, can be conveniently manufactured, saves manufacturing cost and has strong practicability. ", it is pressed from both sides tight through two splint that set up, it is tight with the contact line, and fix through locating pin and retaining member, thereby accomplish the contact line and press from both sides tight, simple to operate, simple structure and easy production simultaneously, but it is in the application, because there is the screw to fix, in long-term use, the screw can loose the condition take place, thereby make the device unstable in practical application, lead to the emergence accident, the device is when carrying out the centre gripping to the line of different distances simultaneously, unable adjustment centre gripping width, thereby lead to the device inconvenient in use. Therefore, the wire clamp for the railway contact network solves the problems. Disclosure of utility model The utility model aims to provide a wire clamp for a railway contact network, which solves the problems in the background technology. In order to achieve the above purpose, the technical scheme is that fixing bolts are arranged at four corners of the outer side of a first clamping block, the fixing bolts can further strengthen connection between the two clamping blocks, a first suspension fixing block is arranged at one side of the first clamping block, a first threaded hole is formed in the center of the first suspension fixing block, a threaded rod is arranged in the first threaded hole, a mortise and tenon block is arranged at the other side of the first clamping block, a contact line is arranged below the mortise and tenon block, a second clamping block is arranged at one side of the mortise and tenon block, fixing threaded openings are formed in four corners of one side of the second clamping block, the inner diameter of the fixing threaded openings is matched with the outer diameter of the fixing bolts, a second suspension fixing block is arranged at the other side of the second clamping block, a second threaded hole is formed in the center of the second suspension fixing block, a threaded rod is arranged in the second threaded hole, a mortise and tenon groove is formed in one side of the second clamping block, and the inner diameter of the mortise and tenon and mortise and tenon groove can be connected firmly and stably. Preferably, a fastening screw is arranged below the first suspension fixing block, and one end of the fastening screw penetrates through the first clamping block and then is fixedly connected with a fixing clamping block. Compared with the prior art, the utility model has the beneficial effects that: The ground wire is clamped through the first clamping block and the second clamping block, the first threaded hole is formed in the first hanging mode, the second threaded hole is formed in the second hanging mode, the clamping width can be adjusted when wires with different distances are clamped, the device is convenient to use, the mortise and tenon joint blocks are connected with the mortise and tenon joint grooves, the mortise and tenon joint grooves are designed in a self-locking mode, and when a 350km/h train passes through, the amplitude attenuation rate is 65% higher than that of a screw, so that the stability of the wire clamp is improved. Through the setting of fastening screw and fixed buckle, can be with the contact line more stable.
