Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Hydraulicdriven changing machine is adopted in prior art, technical requirements due to hydraulicdriven element is high and assembling is more difficult, hydraulic oil is easily revealed, working service is relatively stricter, and needs independently Hydraulic Station supply hydraulic oil, structure relative complex, operate also more loaded down with trivial details, therefore constantly convert in the railway track replacing operation of workplace at circuit length, needs, it is very inconvenient that use is carried, and is also unfavorable for the raising of operating efficiency.
And adopt jack, pulley, chaindriven changing machine, also have that fabrication and installation requirement is high, the defect of complex structure, complex operation, be also unsuitable for the feature that rail track is long, workplace is not fixed, needed quick-replaceable to keep in repair.
The utility model, for the defect existed in prior art, adopts motor as drive source, utilizes worm and gear to form transmission, drives lifting screw 18 to move up and down, and then rises the rail needing to change.
Concrete structure is: see Fig. 1, Fig. 2, the transmission case 3 that the utility model comprises base 11 and is fixed thereon, in described transmission case 3, Worm Wheel System pair is installed, worm screw 19 is provided with belt pulley 16, be connected by V belt translation with the motor 15 being fixed on base 11 side, lifting screw 18 and worm gear 21 threaded engagement in transmission case 3, lifting screw 18 lower end is hinged with the bearing 12 be positioned at below base 11, screw sleeve 1 is installed on transmission case 3 top, fix with cage guiding seat 2 bolt at top, transmission case 3 is also provided with oil filler point 20, for oily to gear, starter motor 15, drive worm screw 19 to rotate, worm screw 19 drives the worm gear 21 engaged with it to rotate, and worm gear 21 drives lifting screw 18 to rotate, and then drives whole base 11 to rise.
The opposite side of described base 11 is provided with steel rail spring stopping means (see Fig. 1, Fig. 3, Fig. 4, Fig. 5), and steel rail spring stopping means comprises and is fixed on limiting plate 5 on base 11 and spring holder; The plunger 6 of described spring holder is placed in fixing key seat 7 on the pedestal 11, and the symmetrical both sides of the outer wall of key seat 7 are welded with joint pin, two joint pins are stuck in and are fixed in the middle key seat frame 10 of base 11, plunger 6 is vertically upspring by the spring 8 be placed in key seat 7, and the lower end of spring 8 is connected with the reinforcement base plate 9 be fixed on the downside of base 11; The upper end of described limiting plate 5 is provided with the bending part moved left and right for limiting rail 4, when operating, one end of base 11 is first through the below of rail 4, and rail 4 contacts above with base 11, to touching plunger 6 and plunger 6 being pressed into key seat 7, rail 4 moves into smoothly, and to limiting plate 5 place, now rail 4 departs from plunger 6, plunger 6 resets under the effect of spring 8, blocking the side of rail 4, making rail 4 can not produce displacement when hoisting and land, strengthen the safety of construction.
The structure of steel rail spring stopping means is not limited thereto, and key seat 7 can also be adopted directly to be fixed on and strengthen on base plate 9, save key seat frame 10, wherein plunger 6 can lengthen, and makes lower end penetrate spring 8, plays effect similar to the above.
See Figure 10; lifting screw 18 swivel nut 22 threaded engagement that arrange interior with worm gear 21; the centre bore interference fit of swivel nut 22 and worm gear 21; the mode that usual employing key connects; ensure that swivel nut 22 can rotate with worm gear 21; can disassemble from worm gear 21 again; such structure is because swivel nut 22 and lifting screw 18 cooperation place are easy to wear; like this when after thread wearing and tearing; can only change swivel nut 22; both convenient for maintaining saved maintenance time, again can be cost-saving, and was also a kind of protection to lifting screw 18.
Base 11 and motor cabinet 14 split are arranged, and are connected as one between base 11 and motor cabinet 14 by connecting bolt 13; Described base 11 is two shaped steel (see Fig. 6) laid side by side, is fixed on the transmission case 3 on base 11, limiting plate 5 is connected as a single entity described two root type steel, described base 11 can also arrange reinforcing rib again; Described shaped steel is square steel, and described screw sleeve 1 is square steel.Adopt this structure, square steel used can adopt waste material, and material consumption economizes, and structure is simple, makes easily.
Lifting screw 18 lower end and the bearing 12 be positioned at below base 11 adopt hinged mode, make lifting screw 18 have certain degree of freedom, to adapt to the needs of difference in height in process is risen and fallen in construction.
Also be fixed with handle 17 in the both sides of screw sleeve 1, handle 17 role is that convenient construction personnel help.
The utility model is developed mainly for above-mentioned defect, has both achieved the safety and steady changing the section of track in track switch work progress and has risen and fallen, simple to operate again, and conveniently, practical is strong for installing/dismounting and rising and dropping control.Its principal character: the parts such as the V belt translation in the source that is used as power by worm and gear, lifting screw 18, motor 15 form, structure composition is simple, Movement transmit is simple and direct, there is auto-lock function, safe and reliable, during site operation, by organize more described railway switch electronic replaing-machine with the use of, be applicable to singly to open, compound friendship grade Multiple Type track switch.
Find through the construction of spot replace track switch: railway switch electronic replaing-machine achieves changes track switch section of track safety, quiet takeoff and landing in track switch overhaul work progress, and do not limit by track switch model and Active workings, change the complicated model track switch effects such as compound friendship divides, double crossover particularly evident, there is application value.
