Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing.
The structural representation of transition components is represented see Fig. 1-3, Fig. 1-3.Transition components 11 comprises wheel shaft supporting seat 111 and jack 112, and jack 112 drives wheel shaft supporting seat 111 jack-up or falls wheel shaft 2, wheel shaft supporting seat 111 for around jack 112 center rotating and drive wheel shaft 2 to rotate.Transition components 1 is for jack-up and rotating axle 2, and wheel shaft 2 is converted assembly 11 jack-up and after rotating, miscellaneous equipment can be utilized to be carried out by wheel shaft 2.
As shown in Figure 1, wheel shaft 2 comprises axletree 21 and wheel 22, and axletree 21 is for connecting two wheels 22.Under normal circumstances, two wheels 22 are erected on two rails 3 respectively.When wheel shaft 2 et out of order, need to change wheel shaft 2, need wheel shaft 2 to remove from rail 3.When using transition components 11, immediately below the axletree 21 first transition components 11 being placed on wheel shaft 2, the center of transition components 11 is aimed at the center of axletree 21, and now jack 112 is inserted in wheel shaft supporting seat 111; Then, as shown in Figure 1-2, protruded upward by jack 112, jack 112 jack-up wheel shaft supporting seat 111, wheel shaft supporting seat 111, by axletree 21 jack-up of wheel shaft 2, makes wheel 22 and rail 3 depart from; Then, wheel shaft supporting seat 111 around the center rotating 90 ° of jack 112, and drives wheel shaft 2 also to rotate 90 °, after wheel shaft 2 rotates 90 °; Finally, retracted downwards by jack 112, wheel shaft supporting seat 111 falls after rise, and wheel shaft 2 also falls after rise together, now can be placed on other equipment by wheel shaft 2, such as, in the track (not shown) of laying in addition, is removed by wheel shaft 2 along track.
Because limiting by interval landform and row inspection operation field condition, distributing failure emergency repair vehicle in some environments can not near rail, and lifting appliance cannot be organized work smoothly by external environment influence.Transition components of the present utility model can with distributing failure emergency repair vehicle with the use of, radical function utilizes transition components 11 by wheel shaft jack-up and wheel shaft 2 is transferred to assignment station track, or wheel shaft 2 is transferred to the place that lifting appliance can launch, complete the operation that changes the outfit of rolling stock fault wheel shaft rapidly; Under emergency conditions, by this transition components 11, wheel shaft 2 can also be cleaned out outside circuit fast, ensure that circuit is open-minded rapidly, realize the object that railway traffic accident is repaired fast, fast quick-recovery is opened.
In the present embodiment, as illustrated in figures 4-5, wheel shaft supporting seat 111 comprises the wheel shaft support slot 111a of strip shape and is connected to the columnar jack Connection Block 111b of wheel shaft support slot 111a bottom centre.As shown in Figure 2, wheel shaft support slot 111a is for supporting the axletree 21 of wheel shaft 2, and the piston rod 112a of jack 112 is inserted in jack Connection Block 111b, piston rod 112a and jack Connection Block 111b free-running fit.When jack-up wheel shaft 2, the length direction of the wheel shaft support slot 111a of strip shape is arranged along the axial direction of axletree 21, the circumference contact of the groove face of wheel shaft support slot 111a and the axletree 21 of wheel shaft 2, holds up wheel shaft 2.After jack-up wheel shaft 2, jack 112 keeps motionless, now only has wheel shaft supporting seat 111 to rotate, and due to piston rod 112a and jack Connection Block 111b free-running fit, wheel shaft supporting seat 111 can ease rotation, and drives wheel shaft 2 to rotate simultaneously.
In the present embodiment, as shown in Figure 5, the cross-sectional plane of wheel shaft support slot 111a is U-shaped, and wheel shaft support slot 111a is rectangular channel.This grooved can coordinate the axletree 21 of different size.
Preferably, the cross-sectional plane of wheel shaft support slot 111a can be also V-type, also can coordinate the axletree 21 of different size.Certainly, the fitting surface of wheel shaft support slot 111a and axletree 21 can also be circular arc, but this shape can only coordinate the axletree 21 of fixed measure, when the external diameter change of axletree 21, needs the wheel shaft support slot 111a selecting the size that matches.
In the present embodiment, as Figure 1-3, transition components 11 also comprises jack permanent seat 113.As shown in figs 6-8, jack permanent seat 113 comprises base plate 113a and fixed mount 113b, and fixed mount 113b is arranged on the top of base plate 113a, and fixed mount 113b is for inserting the base 112b of jack 112.Jack permanent seat 113, for fixing and support jack, is placed on smooth ground during use, then inserts jack 112 by jack permanent seat 113.The area of base plate 113a is greater than the area of fixed mount 113b, base plate 113a and earth surface, can firm support jack 112, and disperse the pressure of jack 112, prevent jack 112 when promoting, because pressure is excessive, jack permanent seat 113 is down trapped in ground.Fixed mount 113b is used for fixing jack 112, prevents jack 112 from rocking.
Preferably, transition components 11 also can not comprise jack permanent seat 113, is directly placed on smooth, solid ground by jack 112.
In the present embodiment, as shown in Figure 8, fixed mount 113b is surrounded by three angle steel that three side sealing closes, the rectangular channel of an opening.The one side of opening enters for facilitating the base 112b of jack 112, and other three of closing are for limiting base 112b.
In the present embodiment, as shown in figs 6-8, jack permanent seat 113 also comprises the movable handle 113c be arranged on base plate.Movable handle 113c comprises a pipe, two reinforcing bars and two annulus be fixedly connected with base plate 113a, and one end of reinforcing bar is inserted in annulus, and the other end is connected with pipe.Movable handle 113c is flexibly connected with base plate 113a, can conveniently extract and carry jack permanent seat 113.
The utility model has the following advantages:
(1) reduce the operation intensity of repairing team member, reduce personnel and drop into, operating personnel is reduced to 4 people by more than 8 people in the past, saves human input;
(2) improve first-aid repair efficiency, production time foreshortens to 40 minutes in more than 2 hours by the past;
(3) reduce manual operation link, secondary potential safety hazard is eliminated, and operation process safety is controlled;
(4) decrease the dependence to heavy mechanical equipment, avoid the expensive expense using large-scale lifting appliance to produce, when this covering device uses, do not produce extra cost;
(5) achieve the diversification of emergency first-aid repair means, improve repairing team member emergency treatment ability in complex situations;
(6) cost is low, light, and structure is simple, and be easy to assembling, safety of operation, practicality is good.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, other modification some can also be made, also should be considered as protection domain of the present utility model.
