Abstract
The utility model discloses a square guide rail sliding block bearing device for railway vehicle only, and the structure of which is that left and right short guide poles at both ends of the square guide rail are respectively arranged at a base plate by a bracket. The left and right short guide poles are respectively provided with a small hanging rack and the square guide rail is connected between the two small hanging racks; an upper sliding block and a lower sliding block are respectively arranged at the upside and underside of the square guide rail and are respectively connected by a connection board and a door frame. The small hanging racks are fixed on a vehicle body and connected with a transmission shaft by a flap. The connection board is pushed by a power supply to drive the sliding blocks to move in the guide rail. Simultaneously, the connection board 3 moves along a Sylar rail by an idler wheel. The short guide pin 1 forms a cross coordinate with the square guide rail 5. The sliding block bearing device of the utility model has the advantages that: 1) the guide rail sliding block bearing device is adopted as a bearing mechanism to reduce the quantity and weight of the guide rail; therefore, the structure becomes more compact and the occupied space of the bearing mechanism is reduced; 2) the special structure ensures that the bearing capacity of the guide rail is increased and the running is smooth; 3) a modular structure leads to convenient installation, debugging and maintenance.
Description
Technical field
The utility model relates to the special-purpose single-rail slide block of a kind of rail vehicle door system rail vehicle bogey.Belong to the load carrier technical field.
Background technology
Develop rapidly along with socioeconomic, the inter-city passenger rail passenger traffic can not be satisfied the demand of society, pleasant property, reliability and safety that inter-city passenger rail passenger traffic public transportization, rapid requirement improve stopping sliding door.The volume of the flow of passengers of intercity passenger traffic is bigger, the corresponding increase of passenger getting on/off flow, therefore to increase the quantity of every joint car door and the aperture of increase door, and along with the high speed of inter-city train, sealing performance, sound insulation value, heat-proof quality, safety, reliability to door system are had higher requirement, and have increased the difficulty of door system technology.There is following defective in existing bogey: 1) take up room or length bigger, structure is not compact, 2) supporting capacity is little,
Summary of the invention
The purpose of this utility model is intended to overcome the defective of above-mentioned existence.Adopt the function of the two guide rails of bearing guide rail realization of square structure.
Technical solution of the present utility model: its structure is that the left and right short guiding column of square rail both sides is installed on the substrate by support respectively, and a little hanger respectively is installed on the left and right short guiding column, connects square rail between two little hangers.Top shoe and sliding block lay respectively at the upper and lower sides of square rail, top shoe and sliding block respectively by junction plate with take door frame and join.
Advantage of the present utility model: 1) adopt the guide rail slide block device as load carrier, reduced the quantity of guide rail, make structure become compact, reduced the load carrier occupation space, 2) square structure makes the supporting capacity of guide rail increase, and operates steadily; 3) modular construction makes Installation and Debugging easy to maintenance.
Description of drawings
Guide rail schematic diagram when accompanying drawing 1 is door opening state,
Accompanying drawing 2 is guide rail schematic diagrames when closing the door state.
Among the figure 1 is short guiding column, the 2nd, and little hanger, the 3rd, junction plate, the 4th, top shoe, the 5th, square rail, the 6th, sliding block.
The specific embodiment
Power source promotes top shoes 4 by junction plate 3 and sliding block 6 moves along square rail 5, simultaneously junction plate 3 by roller along a plug draw orbital motion, short guiding column 1 and square rail 5 across coordinates; When top shoe 4 and sliding block 6 are mobile in opposite directions on guide rail, realize the opening and closing campaign of door.
The above and below of square rail 5 several slide blocks that respectively distribute, the number of slide block are determined as required.
Claims (2)
1, the special-purpose square rail slide block of rail vehicle bogey is characterized in that the left and right short guiding column of square rail both sides is installed on the substrate by support respectively, and a little hanger respectively is installed on the left and right short guiding column, connects square rail between two little hangers; Top shoe and sliding block lay respectively at the upper and lower sides of square rail, top shoe and sliding block respectively by junction plate with take door frame and join.
2, the special-purpose single-rail slide block of rail vehicle according to claim 1 bogey is characterized in that respectively there are one or several slide blocks the above and below of square rail.
