Abstract
The utility model discloses a supporting frame of a contact rail protecting cover, which comprises a supporting frame body (1). Grooves (2) with downward openings are arranged in the middle of the supporting frame body (1) and contain the upper portion of a contact rail; an antiskid device is arranged inside each groove (2); and the supporting frame of the contact rail protecting cover closely matches with the contact rail.
Description
Technical field
The utility model relates to the city traffic field, specifically is a kind of bracing frame 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 cover 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, and described general position protective cover 102 covers outside the bracing frame 101; 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 in electrical connection place of contact rail 104 as the insulating support place at contact rail 104, described specific position protective cover 103 covers outside the general position protective cover 102.
There is following defective in the bracing frame of the contact rail protective cover of above prior art: because contact rail top is contained in the groove of bracing frame, but both cooperations are not tight, under external force, bracing frame may slide along the contact rail length direction, like this, bracing frame can not support reliably and cover its outer general position protective cover and specific position protective cover, so there is potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is that a kind of bracing frame of contact rail protective cover closely that cooperates with contact rail is provided.
Technical solution of the present utility model is, a kind of bracing frame with contact rail protective cover of following structure is provided, it comprises the bracing frame body, and the middle part of described bracing frame body is provided with the groove on the ccontaining contact rail top that Open Side Down, is provided with anti-skid device in each groove.
After adopting above structure, the bracing frame of the utility model contact rail protective cover compared with prior art has the following advantages:
Because be provided with anti-skid device in each groove, like this, contact rail and groove closely cooperate, even if under external force, bracing frame can not slide along the contact rail length direction yet, and bracing frame can secure support cover its outer general position protective cover and specific position protective cover, so avoided potential safety hazard.
As improvement, described anti-skid device is positioned on two lower walls of groove, and like this, the deadweight of contact rail is pressed on two lower walls of groove, so anti-skid device is contained in this position, its skidproof effect is better.
As improving, described anti-skid device is meant the reinforced rib of epirelief in the groove lower wall again, and is like this, under the prerequisite that guarantees skidproof effect, relatively simple for structure.
As further improvement, each lower wall is provided with two reinforced ribs, totally four of described reinforced ribs, and like this, under the prerequisite that guarantees skidproof effect, structure is simpler.
As further improving, described reinforced rib extends along the contact rail length direction, like this, makes that the knockout course behind this bracing frame casting complete is simple and convenient again.
As also further improving, the lower wall of described groove and the angle between the horizon are less than the lower inclined plane on contact rail top and the angle between the horizon, like this, after contact rail is fitted in the conduit of bracing frame, interference fit between conduit and the contact rail, make that bracing frame more is difficult for skidding, avoid potential safety hazard.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of prior art contact rail protective cover.
Fig. 2 be the utility model contact rail protective cover bracing frame face structural representation.
Shown in the figure
The parts of the contact rail protective cover of prior art: 101, bracing frame, 1011, groove, 102, the general position protective cover, 103, the specific position protective cover, 104, contact rail, 1041, the lower inclined plane on contact rail top.
The parts of the bracing frame of the utility model contact rail protective cover: 1, bracing frame body, 2, groove, 3, lower wall, 4, reinforced rib.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the bracing frame of the utility model contact rail protective cover, it comprises bracing frame body 1, the middle part of described bracing frame body 1 is provided with the groove 2 on the ccontaining contact rail top that Open Side Down.Two lower walls 3 of each groove 2 are provided with anti-skid device, and promptly epirelief is in the reinforced rib 4 of groove 2 lower walls 3.Each lower wall 3 is provided with two reinforced ribs 4, totally four of described reinforced ribs 4.Described reinforced rib 4 extends along the contact rail length direction.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model not only is confined to above embodiment, and its concrete structure allows variation, also can be positioned at as: described anti-skid device on two sidewalls or upper wall of groove 2; Described reinforced rib 4 can not continue along the contact rail length direction yet; The total number of described reinforced rib 4 can also be not to be other numbers of 4; Described anti-skid device can also adopt following structure, and the lower wall 3 of described groove 2 and the angle between the horizon are less than the lower inclined plane (referring to 1041 among Fig. 1) on contact rail top and the angle between the horizon; Or the like.All various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
