Abstract
The utility model relates to a short crank connecting rod-type car side door opening and closing device of a railway automatic dumping car, which comprises two sets of short crank connecting rod drive mechanisms symmetrically arranged between a compartment assembly and a chassis assembly, and the short crank connecting rod drive mechanisms comprise roller wheels, short cranks, connecting rods, pin rolls, side door hinges and abrasion plates. The middle hinge points of the short cranks of the two sets of short crank connecting rod drive mechanisms are respectively connected by the pin rolls and the two hinge points of the bottom of the chassis assembly. One end of each roller wheel and one end of each connecting rod are respectively hinged with the hinge points of both ends of the short cranks; the other end of the connecting rod is hinged with the side door hinges; the abrasion plates are arranged on the chassis assembly; and the roller wheels are pressed on the abrasion plates. The guide surfaces of the short crank connecting rod-type car side door opening and closing device of the railway automatic dumping car are the horizontal planes of the abrasion plates on roller wheel brackets and has simple structure and is easy to manufacture and maintain.
Description
Technical field
The utility model relates to the cabin side device for opening/closing door, refers to the short crank-linkage type side door of a kind of railway automatic dumping car opening and closing device particularly.
Background technology
Railway automatic dumping car is a kind of railway truck, and the compartment of this kind car relies on the promotion of pneumatic or hydraulic pressure tilt cylinder to 40 ° to 45 ° of lopsidedness, opens side door simultaneously, and the lorry that goods is drawn off automatically is used to transport block or granular goods.
At present, a large amount of railway automatic dumping car side door opening and closing devices that use of China are made up of folding, inhibition elbow, roller, inhibition spring, supporting etc., and it is the follow mechanism that the control side door opens and closes.When the compartment assembly is tumbled, suppress the elbow roller and enter the folding curved surface, when the compartment assembly continues to tumble to 45 °, roller is all run through the folding curved surface and is entered the folding root, the right side folding is all opened, at this moment the folding tail end contacts with shotpin on the compartment assembly, makes side door plate face and floor be 45 ° of angles with ground simultaneously, realizes unloading fully.
Above-mentioned existing railway automatic dumping car side door opening and closing device structure more complicated, side door folding, inhibition elbow, chevron pointing supporting, side's supporting etc. are steel casting, the manufacturing process complexity, cost is higher.The guidance mode of tumbling in the operation process is the curve of vertical surface, and the precision of guiding depends on the appearance curve profile of foundry goods, and guiding accuracy is difficult to improve.In addition, existing apparatus packaging technology complexity, maintenance difficulty, side door gap adjustment trouble.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model will provide exactly, from heavy and light, and the short crank-linkage type side door of the railway automatic dumping car opening and closing device that cost is low.
For achieving the above object, the designed short crank-linkage type side door of the railway automatic dumping car opening and closing device of the utility model is made up of the symmetrical short crank linkage driving system that is arranged between compartment assembly and the chassis assembly of two covers, and short crank linkage driving system comprises roller, short crank, connecting rod, bearing pin, is fixed on the side door folding and the wearing plate of side door lower edge.Establish three hinge-points on the short crank, the middle hinge-point of the short crank of the short crank linkage driving system of two covers links to each other by two hinge-points of bearing pin and compartment assembly bottom respectively, and an end of roller and connecting rod links to each other with the two ends hinge-point of short crank respectively.Wearing plate is arranged on the top of chassis assembly.The connecting rod other end and side door folding are hinged, and roller is pressed and put on wearing plate.
For rigidity and the intensity that increases short crank, short crank is designed to triangular structure, and the hinge-point of short crank and roller, connecting rod and compartment assembly lays respectively at leg-of-mutton three drift angle places.The thickness of adjusting wearing plate can be regulated the gap between side door and the compartment assembly.
Advantage of the present utility model is: the spigot surface of the short crank-linkage type side door of the utility model railway automatic dumping car opening and closing device is the horizontal plane of wearing plate, do not need the curved profile guiding, the precision of guiding guarantees by the position of leverage and hole system, and is simple in structure, be suitable for and make and maintenance.
Description of drawings
Fig. 1 is the mounting structure scheme drawing of the short crank-linkage type side door of the utility model railway automatic dumping car opening and closing device;
Fig. 2 is the connection structure scheme drawing of roller, crank and connecting rod among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The short crank-linkage type side door of railway automatic dumping car shown in Figure 1 opening and closing device, mainly be made up of the symmetrical short crank linkage driving system that is arranged between compartment assembly 7 and the chassis assembly 8 of two covers, described short crank linkage driving system is made of roller 1, short crank 2, connecting rod 3, bearing pin 4, the side door folding 5 that is fixed on side door 6 lower edges and wearing plate 9.Short crank 2 structures triangular in shape are provided with three hinge-points at three drift angle places, and an end of roller 1 and connecting rod 3 links to each other with the two ends hinge-point of short crank 2 respectively, as shown in Figure 2.Hinge-point links to each other with two hinge-points of compartment assembly 7 bottoms by bearing pin 4 respectively in the middle of the short crank 2 of the short crank linkage driving system of the symmetrical layout of two covers.The wearing plate 9 that thickness is adjustable is welded on the top of chassis assembly 8, and connecting rod 3 other ends and side door folding 5 are hinged, and roller 1 is pressed and put on wearing plate 9.The piston rod of tilt cylinder 10 is articulated in the downside of compartment assembly 7, and the homonymy of hinged center and compartment assembly 7 is tumbled center of turn on same axis, and cylinder barrel is articulated in the side of chassis assembly 8.
Under discharging situation as shown in Figure 1, the piston of tilt cylinder 10 is overhanging, promotes compartment assembly 7 and rotates around the rotating shaft of chassis assembly 8.In the process of tumbling, roller 1 is pressed in all the time on the wearing plate 9 and rolls, and side door 6 coordinated movements of various economic factors of short crank 2, connecting rod 3 and compartment assembly 7, discharge side are opened the side door 6 of discharge side gradually.When the piston of tilt cylinder 10 bounced back, compartment assembly 7 fell after rise under its deadweight effect gradually, and side door 6 coordinated movements of various economic factors of short crank 2, connecting rod 3 and compartment assembly 7, discharge side are closed the side door 6 of discharge side gradually.
