Abstract
The utility model relates to a side frame device with double stop key structures. The side frame device comprises a side frame and a stop key mounted on the inner side of a guide frame of the side frame. The side frame device is characterized in that a bolt and nut assembly is mounted on the outer side of the guide frame, the axial direction of a bolt is consistent to that of the stop key, and the head of the bolt is wedge-shaped and is opposite to the stop key. The side frame device is simple in structure and is operated easily, and the stress condition of the side frame can be improved.
Description
Technical field:
The utility model relates to a kind of pair of block key structure side rack device, belongs to the field of components of the steering swivel system of rolling stock.
Background technology:
Bogie side frame is the basis of bogie truck, it bogie truck each zero, parts form a whole.So it not only bears, transmits various effects and load, and its structure, shape and size size all should satisfy each zero, structure, shape and the stack-mounted requirement of parts.When normal vehicle operation, bogie side frame and wheel are to transmitting onward impulse through axle box, and the drawing strickle guide of bogie side frame inserts in the guide groove of adapter (or axle box), and the effect of drawing strickle guide and guide groove has limited front and back and downward motion between axle box and the bogie side frame.But when the carrying bogie truck or when using the tipper unloading, it is broken away from, block key is exactly for preventing that the wheel design-calculated that comes off is installed in the disconnecting prevention structure on the bogie side frame.
Previous block key is the independently part that can dismantle arbitrarily, and an end is installed in the inboard of side frame guide.During normal the operation, block key and axle box keep certain clearance, and be inoperative.When integral body carrying bogie truck, block key and bearing are close together, and prevent that wheel is to break away from the whole.This block key has a kind of fatal defective, can be random disassemble, though conveniently assemble and disassemble, maintenance is stolen easily.Through improving, produce block key now and all be riveted on the bogie side frame through bolt, nut.Though such block key has solved the antitheft problem, still have certain defective, it is one-sided block key, analyzes from the mechanics angle, this is irrational.When bogie truck was promoted by integral body, wheel was to the pressure very big to the block key output, and its size is for taking turns right gravity and the side frame guide outside to axletree pressure sum.If bogie truck shakes in lifting process, wheel will acutely increase pass to the inboard power of side frame guide through block key.
Summary of the invention:
The purpose of the utility model is in order to reduce the inboard application force of bogie truck when carrying side frame guide; Optimize the stressing conditions of bogie side frame; Can keep existing block key advantage of simple structure; And can overcome existing block key device because the bolt that causes simple in structure bears the deficiency that pulling force brings more greatly, a kind of pair of block key structure side rack device is provided.
The purpose of the utility model realizes in the following manner:
The utility model comprises the block key that bogie side frame is inboard with being installed in side frame guide, it is characterized in that: a cover bolt, nut are installed in the drawing strickle guide outside, bolt axially and block key axial consistent, bolt head is a wedge shape, bolt head and block key are relative.
The utility model has the advantages that: simple in structure, easy to operate, can improve the stressing conditions of bogie side frame.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the I portion cutaway view of Fig. 1;
Fig. 3 is the front view of wedge hook bolt;
Fig. 4 is the right elevation of wedge hook bolt;
Fig. 5 is the running condition figure of the utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises the block key 2 that bogie side frame 1 is inboard with being installed in bogie side frame 1 drawing strickle guide, and bogie side frame 1 is the cast steel structure, and it is inboard that block key 2 is installed in bogie side frame 1 drawing strickle guide through bolt 3, nut 4, packing ring 5, rivet 6.Bore the circular hole of a Φ 17 in the both sides external of side frame guide; Be used to install wedge hook bolt 11; Wedge hook bolt 11 usefulness check washers 9, bearing cap shim 10, nut 8 are installed on the circular hole in the drawing strickle guide outside of bogie side frame, and a pin 7 that prevents that nut from getting loose is installed on bolt shank.The wedge hook bolt axially and block key axial consistent, bolt head and block key are relative.
The utility model overlaps bolt, nut, check washer, bearing cap shim in the drawing strickle guide outside newly-increased outside keeping original block key.Newly-increased bolt shape is special, and head is wedge shape, and is as shown in Figure 5, and it can be considered another block key on the bogie side frame, has so just formed the bogie side frame structure of two block key structures.Can regulate the gap of wheel shaft and bolt through the thickness that changes bearing cap shim.Through mechanical analysis, the stressing conditions that is easy to calculate bogie side frame improves.And since the existence of wedge hook bolt can the length of stretching out of original block key be reduced.Former block key can be reduced to a cantilever beam structure, if the arm of force reduces, the moment of flexure of its end will reduce thereupon.
