Abstract
The invention discloses a screw type top iron for a track switch, comprising a T-shaped top iron body, a steel rail gasket used in cooperation with the top iron body, a screw with a limiting plane, an anti-loosening gasket cooperating with the screw limiting plane, a fastening nut, and an anti-rotation sheet preventing loosening of the fastening nut; the top iron body is provided with a first screw through hole with screw threads and substantially perpendicular to the front end surface of the top iron body; the steel rail gasket is provided with a second screw through hole corresponding to the first screw through hole on the top iron body, the part of the steel rail gasket external side located at the second screw through hole is provided with a limiting protruding part preventing rotation of the anti-loosening gasket; the screw cooperates with the screw threads of the first screw through hole on the top iron body, and together with the fastening nut, connects the top iron body and the steel rail gasket. By employing the above structure, the screw type top iron for a track switch can conveniently adjust the length of the top iron, thereby improving operating efficiency of adjusting the top iron.
Description
Technical field
The invention belongs to track component, the screw track switch that is specifically related to a kind of railway switch use is used top iron.
Background technology
Top iron is the important component part of railway switch, and effect is that supporting rail spare guarantees that track switch is linear.What at present track switch was used is all-in-one-piece top iron, and rail spare is pulled down top iron earlier carrying out the position when adjusting, increase then, subtract iron rear portion, top trimmer change top iron length, perhaps the front end of polishing, repair welding top iron is realized the adjustment of top iron length; And then reinstall top iron.
Summary of the invention
The purpose of this invention is to provide a kind of convenient screw track switch of regulating length and use top iron, adjust top iron efficiency of operation thereby improve.
The technical solution adopted for the present invention to solve the technical problems is: screw track switch with top iron comprise T shape top iron body, the rail packing ring that is used with top iron body, with spacing plane screw rod, the lock washer, the clamp nut that cooperate with the spacing plane of screw rod, prevent the anti-rotor that clamp nut is loosening; Described top iron body is provided with the threaded first screw rod through hole vertical substantially with its front end face; Described rail packing ring is provided with the second screw rod through hole corresponding with the first screw rod through hole on the iron body of top, and the position that the rail packing ring outside is positioned at the second screw rod through hole is provided with the spacing protuberance that prevents that lock washer from rotating; The threaded engagement of the first screw rod through hole on described screw rod and the top iron body, and together top iron body is connected with the rail packing ring with clamp nut.
The present invention does not change original mounting condition, adopted knockdown top iron, can utilize rail packing ring and screw rod that top iron body is fixed on the rail, the length of stretching out top iron body by rotating screw bolt adjusting screw(rod) front end, utilize the rotation of lock washer restriction screw rod, utilize anti-rotor to prevent that clamp nut is loosening.The present invention can regulate the length of top iron easily owing to adopt said structure, thereby can improve the operating efficiency of adjusting top iron.
The invention will be further described below in conjunction with drawings and Examples.

The specific embodiment
See Fig. 1 to Figure 10, the rail packing ring 2 that screw track switch comprises T shape top iron body 1, is used with top iron body 1 with top iron; The inboard top and the bottom of top iron body 1 are provided with inclined-plane 101, which is provided with two fore-ends with the vertical substantially first screw rod through hole, 102, the first screw rod through holes 102 of its front end face and are provided with screw thread 103; The inboard top and the bottom of rail packing ring 2 are provided with the inclined-plane 201 identical with top iron body 1, which is provided with two with top iron body on the second corresponding screw rod through hole 202 of the first screw rod through hole 102, the position that rail packing ring 2 outsides are positioned at the second screw rod through hole 202 is provided with the spacing outstanding step 203 that prevents that lock washer 4 from rotating; Also comprise screw rod 3, lock washer 4, clamp nut 6, anti-rotor 5, the bar of screw rod 3 is provided with spacing plane 301; Lock washer 4 comprises square substrate 401, and substrate 401 is provided with boss 402, and substrate 401 and boss 402 are provided with through hole 403, and the inwall of through hole 403 is provided with spacing plane 404 and can cooperates with the spacing plane 301 of screw rod 3; Anti-rotor 5 is provided with two screw holes 502 that cooperate with lock washer 4 convex platforms 402, and its length is greater than the lateral length of rail packing ring 2, and two ends all are provided with opening 501, and anti-rotor 5 is used to prevent that clamp nut 6 is loosening.
The present invention in the Front-end Design of top iron body 1 threaded 103 the first screw rod through hole 102; Screw rod 3 is installed in the first screw rod through hole 102 of top iron body 1 then, and is spun on the screw thread 103, can adjust the adjustment that its front end stretches out the length realization top iron length of top iron body 1 by rotary screw 3, makes the preceding end in contact rail of screw rod 3; In order to realize the locking of screw rod 3, lock washer 4 is installed in spacing outstanding step 203 places of rail packing ring 2, utilizing the outside of its square substrate 401 to prop up spacing outstanding step 203 makes it spacing rotatable, and thereby the spacing plane 404 on through hole 403 inwalls cooperates the rotation that can limit screw rod 3 on the lock washer 4 with the spacing plane 301 of screw rod 3, by the installation that rail packing ring 2 can be realized top iron body 1 is set at the rail opposite side, this also provides a mounting plane for clamp nut 6; After top iron length adjustment is good, tighten clamp nut 6 according to design moment, and the two ends of the anti-rotor 5 of bending loosening with restriction clamp nut 6, so far top iron installs.
When need adjusting, the reverse flat anti-rotor 5 of folding, loosening clamp nut 6 will move slightly behind the lock washer 4, and rotating screw bolt 3 is to the length that is fit to, and then lock washer 4 is installed successively, clamp nut 6 gets final product.
