Description
Technical field: the utility model relates to copper material (or aluminium) the current carrying catenary slip saddle device that a kind of electrification railway contact net is used, and belongs to the electrified railway specialized equipment.
Background technology: the contact system current carrying catenary is that electrified railway (comprises subway, the mine) and important composition partly, undertaking electric locomotive worker's traction power supply task, the contact system current carrying catenary is copper cash or aluminum steel, the contact system current carrying catenary is installed and is placed under the outside state of nature, because the metallic material effect of expanding with heat and contract with cold, installation is placed on the contact netting twine current carrying catenary in the pulley, contact system current carrying catenary after use a period of time, in contact system current carrying catenary and the contact site that hangs pulley, abrasion in various degree appears in the capital, the contact system current carrying catenary is directly through changing, collection carbon increases, after the current carrying catenary abrasion acquires a certain degree, will influence whole contact system current carrying catenary traction power supply function, must change whole contact system current carrying catenary.This had both caused the waste of current carrying catenary resource, increased the electrified railway operation expense again.
Summary of the invention: the purpose of this utility model is to overcome existing technical disadvantages for many years, invent and a kind of whole contact system current carrying catenary is placed on the slip saddle, need not to change whole contact system current carrying catenary, do not influence whole contact system current carrying catenary system height, the basic contact system current carrying catenary abrasion problem that solves, the electrification railway contact net of easy for installation, long service life is with current carrying catenary slip saddle device.
The purpose of this utility model is finished by following array structure: form electrification railway contact net with current carrying catenary slip saddle device by suspension plate, pulley and sheave shaft, its middle pulley is connected with suspension plate by sheave shaft, it is characterized in that being placed with a sliding bar in the pulley groove, at least respectively be connected to a hook type saddle in the sliding bar; Hook type saddle one end and sliding bar flexibly connect; The hook type saddle other end is hook-shaped, tabular; At least have a groove mouth on the hook type saddle other end termination; Wall energy is by the fixation fork of size match in the groove mouth notch of hook type saddle termination; The fixation fork structure is hook-shaped, U-shaped shape, has a captive nut on the fixation fork at least; Sliding bar is shaft-like; Sliding bar is a Metallic rod, and superficial hardness is HRC45-60.
The utility model principle of work is: sliding bar (3) is placed in the groove of pulley (2), the hook type saddle (4) at pulley (2) two ends is being lifted current carrying catenary (7), fixation fork (6) passes the groove mouth (5) in the hook type saddle (4), fork is lived current carrying catenary (7), tighten the nut at fixation fork (6) two ends, fixation fork (6) then is fixed on current carrying catenary (7) in the hook type saddle (4) of sliding bar (3) below.When very long whole contact system natural phenomenon occurs expanding with heat and contract with cold with copper (aluminium) current carrying catenary (7), current carrying catenary (7) self can not move, but the sliding bar (3) that is placed on the pulley (2) is done to move around, wearing and tearing just can not appear in current carrying catenary (7) self like this, when sliding bar (3) when surface abrasion is serious, people only need to change sliding bar (3).For increasing the service life of single sliding bar (3), sliding bar (3) surface and pulley (2) groove surfaces all preferably have certain degree of hardness.
Below the suspension plate (1) of the utility model device, one or several pulleys (2) can be installed, the mounting means of several pulleys (2) is parallel side by side, allows sliding bar (3) pass the mounting means of each pulley (2) in regular turn; Also may be relative in twos, allow sliding bar (3) pass surface groove formation through hole cavity between two pulleys (2).Can have a plurality of through holes that are connected and fixed on the suspension plate (1), be convenient to regulate when people construct whole height of devices.On the suspension plate (1) hook (9) can be installed, different highway sections needs when satisfying construction.Every sliding bar (3) below is equipped with a hook type saddle (4) at least, but preferably adorns two hook type saddles (4), for long current carrying catenary (7), can go up dress 3-5 hook type saddle (4) at a sliding bar (3) simultaneously.
Hook type saddle (4) one ends can be installed on the sliding bar (3) by the socket mode in the utility model device, also may nut etc. alternate manner be installed on the sliding bar (3).The structure of hook type saddle (4) other end is a hook-shaped, allows current carrying catenary (7) be positioned on the hook, uses fixation fork (6) from hook groove mouth (5) current carrying catenary (7) to be fixed on hook type saddle (4) again; The structure of hook type saddle (4) other end is link plate shape also, have at least one groove mouth (5) on the link plate, fixation fork (6) passes this groove mouth (5) and entangles current carrying catenary (7), with the nut fork (6) that is strained and fixed, whole current carrying catenary (7) promptly is fixed on hook type saddle (4) link plate sidepiece again.The structure of hook type saddle (4) other end is other any structure shape also, as long as whole current carrying catenary (7) can be fixed.
Fixation fork in the utility model device (6) structure can be hook-like shape, also U-shaped shape.Fixation fork has captive nut on (6).Sliding bar (3) but stiff rod (as Metallic rod, non-metal bar), the also soft bar of sliding bar (3) (leading etc.) as steel.Sliding bar (3) profile can be cylindric, also can be shapes such as ellipse.
