The risk of falling accidents caused by transverse collision is lowered while realizing bearing and guiding functions; and meanwhile, the door system bearing and guiding device has the advantages of compact structure, high reliability, high safety, high processing technique and low manufacturing cost.
Description
Technical field
The utility model belongs to the door system field, relates in particular to a kind of carrying guiding device that is used on the rail traffic vehicles door system.
Background technology
Along with developing rapidly of China's rail traffic vehicles cause, the reliability of door system, safety, practicality etc. are had higher requirement.Bogey directly determines life-span, reliability, the safety of rail vehicle door system.Traditional " C " type monorail carries guiding device, is bearing under the lateral impact loading situation, and the risk that bearing wheels, anti-jump door leaf of taking turns have the bearing guide rail that comes off is installed.The modified that on the basis of traditional " C " type single track, increases bottom guiding single track carries guiding device, exists the bearing guide rail space bigger, problem difficult in maintenance.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The utility model provides a kind of door system to carry guiding device; Avoid the risk that when receiving side knock, comes off, thus reliability, safety and the application life of having improved the vehicular traffic door system.
Technical scheme: for solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of door system carries guiding device; Comprise bearing guide rail, carry dolly and take door frame that the guide rail inner chamber of said bearing guide rail is that the side is type semienclosed, and opening part is provided with a grade edge; Said carrying dolly comprises mounting bracket, guide roller and carrying roller, and said guide roller all is located on the mounting bracket with the carrying roller, and the axle center of wherein said guide roller is a vertical direction, and the axle center of said carrying roller is a horizontal direction; Said carrying dolly is arranged on the guide rail inner chamber of bearing guide rail, and guide roller is between said guide rail inner chamber and the shelves edge, and said carrying roller rolls along bearing guide rail simultaneously; The said door frame of taking is connected with the mounting bracket that carries dolly.
Said carrying dolly is integrated bogey and guiding device, and make the utility model have concurrently and carry and guide function, and maintenance for convenience detach; Opening part in bearing guide rail is provided with a grade edge simultaneously, and making has the protection of grade edge when receiving horizontal bump, thereby has reduced the risk of carrying dolly generation case accident.
As preferably; Said mounting bracket also is provided with fixed axis; These fixed axis both sides are respectively equipped with the carrying roller; Said mounting bracket through this fixed axis with take door frame and be connected, make one of them carry roller to contact through rotating this fixed axis with the upper wall of said guide rail inner chamber, another carrying roller contacts with the lower wall of said guide rail inner chamber.Thereby two carrying rollers that carry the feasible contact of roller guide rail inner chamber lower wall can regulating fixed axis easily have the bearing wheels function, make the carrying roller of contact guide rail inner chamber upper wall have anti-jump function of taking turns.
Beneficial effect: compared with prior art, the utlity model has following advantage: reduced the risk that case accident takes place when the utility model receives against in the time of with carrying and guide function; Simultaneously, with bearing wheels, anti-jumply take turns, directive wheel is assembled in the same carrying dolly, compact conformation, reliability is high, safety is good, processing technology is good, and is cheap.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the said carrying dolly of the utility model;
Fig. 3 is the cross section structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Shown in accompanying drawing 1～3, a kind of door system carries guiding device, comprises bearing guide rail 1, carries dolly 2 and takes door frame 3, and the guide rail inner chamber of said bearing guide rail 1 is that the side is type semienclosed, and is provided with grade edge 4 in upper shed place; Said carrying dolly 2 comprises mounting bracket 5, guide roller 6 and two carrying rollers 7; This mounting bracket 5 is provided with a fixed axis 8; With two both sides that are located at this fixed axis 8 of carrying roller 7 symmetries; And the axle center of this carrying roller 7 is a horizontal direction, simultaneously guide roller 6 is installed in the top of mounting bracket 5, and the axle center of guide roller 6 is a vertical direction; To carry then in the guide rail inner chamber that dolly 2 is placed in bearing guide rail 1; Make guide roller 6 be between guide rail inner chamber and the shelves edge 4, rotate adjustment fixed axis 8 simultaneously and make one of them carrying roller 7 contact with guide rail inner chamber lower wall that another carries roller 7 and contacts with the upper wall of guide rail inner chamber as " the anti-jump wheel " as " bearing wheels ".The said door frame 3 of taking is used to install door leaf, is provided with through hole taking on the door frame 3, and is connected with fixed axis 8 on the mounting bracket 5.
Said carrying dolly 2 is integrated bogey and guiding device, and make the utility model have concurrently and carry and guide function, and maintenance for convenience detach; Opening part in bearing guide rail 1 is provided with grade edge 4 simultaneously, and making has the protection of grade edge 4 when receiving horizontal bump, carries the risk that case accident takes place dolly 2 thereby reduced.During work, carry dolly 2 and do translational motion along bearing guide rail 1, make that through taking door frame 3 carrying dolly 2 links to each other with door leaf simultaneously, the drive door leaf is accordinged to the slideway of bearing guide rail 1 under the guide effect of directive wheel track moves.
As preferred implementation; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
