Description
Technical field
The utility model relates to the city traffic field, specifically is a kind of contact rail protective cover of underground railway track.
Background technology
At present, city underground adopts the contact rail electric means more, and promptly I-beam section of parallel laid is as contact rail outside two rails, and the subway electric car is subjected to from contact rail by current-collecting device.And because contact rail is generally charged, get an electric shock for fear of the personnel of injection, simultaneously for preventing that contact rail is corroded in air because of long term exposure and damages, and need be provided with the protective case that can play the insulation protection effect on contact rail.
The contact rail protective cover of prior art as shown in Figure 1 comprises along several bracing frames 101 (as establishing every 1.5 meters) of the even setting of contact rail 104 length directions and the general position protective cover 102 that extends along contact rail 104 length directions, the middle part of each bracing frame 101 is provided with the groove 1011 on ccontaining contact rail 104 tops that Open Side Down, each bracing frame 101 cooperates with contact rail 104 tops by groove 1011, each both sides, bracing frame 101 bottom is provided with downward projection 1012, the lower end, two side of described general position protective cover 102 is equipped with the first inside crimping 1021, and described general position protective cover 102 covers bracing frame 101 two projectioies 1012 outer and each bracing frame 101 and all is matched with in first crimping 1021 of general position protective cover 102; And also be provided with specific position protective cover 103 at the specific position of contact rail 104, be provided with insulating support place protective cover, be provided with electrical connection place protective cover as insulating support place in electrical connection place of contact rail 104 at contact rail 104, described specific position protective cover 103 covers outside the general position protective cover 102 and lower end, specific position protective cover 103 two side is equipped with the second inside crimping 1031, and first crimping 1021 of described general position protective cover 102 is engaged in second crimping 1031 of specific position protective cover 103.
There is following defective in the contact rail protective cover of above prior art: because contact rail I-beam section size is determined; in order to satisfy the needs of insulation protection contact rail; general position protective cover and specific position protective cover must hide contact rail substantially; the height that is general position protective cover and specific position protective cover is all determined; and the height of bracing frame also will could guarantee both smooth assemblings near the height of general position protective cover; like this; the material of single bracing frame expends bigger; need a large amount of bracing frames and lay a contact rail; these bracing frame inventory charge amounts stack up; enormous amount, cost are very high.
The utility model content
The technical problems to be solved in the utility model is that the contact rail protective cover of a kind of energy saving in material, reduction cost is provided.
Technical solution of the present utility model is, a kind of contact rail protective cover with following structure is provided, it comprises along several bracing frames of the even setting of contact rail length direction and the general position protective cover that extends along the contact rail length direction, the middle part of each bracing frame is provided with the groove on the ccontaining contact rail top that Open Side Down, each bracing frame cooperates with contact rail top by groove, described general position protective cover covers outside the bracing frame, be equipped with first groove on each bracing frame two lateral wall, be equipped with first raised line that matches with first groove on two madial walls of described general position protective cover, each first raised line embeds in corresponding first groove.
After adopting above structure, the utility model contact rail protective cover compared with prior art has the following advantages:
Because each bracing frame cooperates with contact rail top by groove, described general position protective cover covers outside the bracing frame, be equipped with first groove on each bracing frame two lateral wall, be equipped with first raised line that matches with first groove on two madial walls of described general position protective cover, each first raised line embeds in corresponding first groove, like this, no longer rely on the projection of both sides, bracing frame bottom and the crimping of general position protective cover to cooperate between bracing frame and the general position protective cover, the both sides of the bottom of bracing frame then need not to extend to the lower end of general position protective cover, so can reduce the height dimension of each bracing frame, be that each bracing frame can both be saved a certain amount of material, and a contact rail needs a large amount of bracing frames, the amount of the material that these bracing frames are saved stacks up, and quantity is very big, reduces cost significantly.
As improvement, it also comprises the specific position protective cover that extends along the contact rail length direction, described specific position protective cover covers outside the protective cover of general position, be equipped with second groove on two lateral walls of described general position protective cover, be equipped with second raised line that matches with second groove on two madial walls of described specific position protective cover, each second raised line embeds in corresponding second groove, like this, lower end at the specific position protective cover also need not be provided with crimping, like this, simplify manufacturing process, reduced cost.
As improving, described first groove, first raised line, second groove, second raised line all are inclined upwardly again, and like this, cooperating between bracing frame and the general position protective cover, between general position protective cover and the specific position protective cover is more firm.
