Detailed description of the invention
As shown in Fig. 3-11, the embodiment of the present invention provides a kind of light rail soil residue vehicle, and this native slag car comprises:
Slag bucket 3, for holding dregs and about line of centers 30 symmetrically shape; Two ends have the suspension shaft 31 for lifting and the S. A. 32 for supporting; The line at two suspension shaft 31 centers overlaps with the line of centers 30 of slag bucket, and the line at two S. A. 32 centers is positioned at line of centers 30 homonymy of slag bucket; See Fig. 3-5;
Underframe 2, for carrying slag bucket 3, end face has two with the locating plate 23 of S. A. 32 position adaptation, locating plate 23 offers U-lag 24, S. A. 32 is placed in this U-lag 24 respectively; Two ends have the towed hitch bar 21 for connecting; See Fig. 6-8;
Running part 4, is made up of 40 two wheels, and eachly to take turns 40 by axletree 41, be fixed on two wheels 42 on car 6 axle 41 and rotary connection is formed at the journal box body 43 of axletree 42 end, wherein underframe 2 is supported on journal box body 43 by elastic element 50; See Fig. 3-5;
Pneumatic brake systems, comprise four brake units 6, brake unit is formed by brake cylinder 61, connecting rod 62 and being articulated on connecting rod 62 and for the brake shoe 63 of felly of conflicting, brake cylinder 61 is fixed on underframe 2, connecting rod 62 one end is articulated on underframe 2, piston rod 613 pivot joint of the other end and brake cylinder.See Figure 10,11;
Light rail soil residue vehicle provided by the invention, during slag dumping, suspender is used to hang on the suspension shaft 31 at slag bucket two ends, with crane slag bucket sling and be placed on brace table, now S. A. departs from locating plate, and card is established with in the draw-in groove of the hold-down arm on brace table, operation crane makes it slowly transfer suspender, because S. A. is positioned at slag bucket symmetrical center line homonymy and strong point bias, therefore slag bucket can overturn to the side relative to S. A. under self gravitation effect, thus the native slag in slag bucket is poured in the region of specifying, after toppling over, operate crane rising suspender again slag bucket is sling and is positioned on underframe, now S. A. has departed from the draw-in groove of hold-down arm and has been placed in the U-lag of underframe locating plate, locating plate limits slag bucket two ends and moves along its length, U-lag moves by limiting S. A. and then limiting slag bucket both sides broad ways, therefore can slag bucket be limited on underframe by locating plate and U-lag, be connected with the locomotive of shield machine for making the native slag car by the towed hitch bar on underframe, also more piece soil slag car head and the tail can be made to connect use, the wheel of running part is placed in also orbiting on track, elastic element connects running part and underframe and plays the effect of vibration damping, when the soil slag car needs to brake, by the pressure adjusted to the air inlet in brake cylinder, piston is moved, and drive brake shoe and wheel to conflict by connecting rod to realize, during normal operation, the pressure of the air inlet in adjustment brake cylinder makes piston reverses direction move can realize release of brake.
The present embodiment passes through a part of model such as 13m
3the model of underframe and running part and Pneumatic brake systems unified by the following native slag car, and then reduce the kind of parts, the native slag car of different model only needs to change slag bucket when changing, the native slag car of Multiple Type shares a set of underframe, running part and Pneumatic brake systems, greatly reduces purchase cost, logistics cost, manufacturing cost and after service cost.
As the detailed description of the invention of running part, see Fig. 9, axletree and incorporated in vehicle wheels position adopt interference fit, both are made to combine securely, do not allowed any loosening phenomenon, axletree is rotaryed connection by double-row conical bearing 45 with journal box body, and bearing inner ring and axle journal adopt interference fit, use M16 × 35 lock bolt dust slinger 46 and bearing inner ring to be fixed simultaneously, realize the position of bearing inner ring in axis; Outside race and journal box body adopt transition fit, are pressed on outside race by M16 × 160 bolt by transparent cover 47, are pressed on journal box body by end cap 48.
Dust slinger 46 is also known as dust guard, and with axletree interference fit, what rotated by its end land is got rid of oily effect and can prevent sewage from entering journal box body; Have T slot in the hole of transparent cover 47, T slot, built with felt pan, plays dustproof effect; End cap seals and is convenient to check bearing.Have abrasion sheet in the outside drawing strickle guide of journal box body, spring load face is provided with spring positioning table 49.
As the preferred implementation of above-described embodiment, as in Figure 3-5, elastic element 50 is one group of spring, this group spring comprises the spring of at least two laid out in parallel, on underframe 2, the position of relative journal box body 43 is respectively equipped with the limited post 60 with quantity such as springs, spring one end is all located on this limited post 60, and the other end is all fixed on journal box body 43.Improve the reliability of elastic element.
In order to avoid adjacent springs, in compression process, catching phenomenon occurs, the two spring rotation directions often organizing arranged adjacent in spring are different.As shown in figure 12, left side spring 51 is left-handed, and right side spring 52 is dextrorotation.
On the basis of above-described embodiment, near the position of journal box body 43, suspension has adapter plate 25 to underframe 2 side, adapter plate 25 lower end has brake cylinder seat 26, brake cylinder cylinder body 611 is installed on brake cylinder seat 26, and brake cylinder piston 612 is towards this journal box body 43, on adapter plate 25, paraxial cabinet end has hangoff receptacle 27, connecting rod 62 is made up of the first bar 621 of end pivot joint and the second bar 622, wherein the first bar 621 end is articulated on hangoff receptacle 27, second bar 622 end and brake cylinder piston rod 613 pivot joint, brake shoe 63 passes through the end pivot joint of connecting panel 64 and the first bar 621 and the second bar 622 pivot joint.Pipe link 64 is fixedly connected with brake shoe 63.
Piston rod 613 drives the second bar 622 translation, second bar 622 drives the first bar 621 to rotate around hangoff receptacle 27, first bar 621 drives and drives brake shoe 63 translation by connecting panel 64, protects the device of other equipment injury brake cylinder, also can prevent brake cylinder from dropping and cause train operation accident.
Cylinder body 612 is divided into the first cavity 100 and the second cavity 200 by brake cylinder piston 611, wherein piston rod 613 is through the first cavity 100, retarding spring 300 is provided with in second cavity 200, retarding spring 300 one end is connected with inboard wall of cylinder block, the other end is connected with piston, first cavity 100 has admission port 101 and exhausr port 102, exhausr port 102 is provided with the blow off valve for emergency braking, admission port 101 connects train pipe 400.See Figure 12.
High pressure air in locomotive main air reservoir is transported to the admission port of each brake cylinder by train pipe 400 by blow off valve, threeway, high pressure hose etc., promoting piston when pressure reaches 450KPa makes retarding spring compress, brake shoe is separated with wheel, when train pipe pressure reduces, retarding spring promotes piston under restoring force effect makes brake shoe contact with wheel, when train pipe blast sharply declines, blow off valve is opened and is communicated with air, realizes emergency braking by retarding spring restoring force.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
