Abstract
The utility model relates to a self-locking steel rail clamp, a left and a right clamping plates of which are correspondingly arranged, wherein the two clamping plates are hinged by using a locking shaft to penetrate in a locking holes in the middle parts of the clamping plates; wedge-shaped blocks are arranged in wedge-shaped grooves at the upper parts of the two clamping plates; the small ends of the wedge-shaped blocks are penetrated with safety pins, and the lower parts form grooves with lower openings, wherein the grooves accord to the end face of a rail head of the steel rail. Thus the steel rail is clamped, when the wedge-shaped blocks are dragged by external force, the steel rail is dragged and is further clamped under the action of pushing and extruding self-locking force of the wedge-shaped blocks. Even when a heavy long rail is dragged, because the self-locking force is increased following the increase of traction force, the dragged steel rail can not slide so as to realize the purposes of no damage on rail surface, reasonable structure, light weight, convenient operation and safety.
Description
The utility model is the various rail types of a kind of 50kg/m to 75kg/m of being applicable to, is particularly suitable for dragging the self-locking rail anchor clamps that the large-tonnage superlong steel rail is used, and belongs to railway track laying operation technique field.
At present, the equipment great majority that are used to long rail is vertically moved are to adopt thread form wedge and door frame to lock the rail anchor clamps of mode, and this mode easily makes the rail face cause the dental impression that surpasses regulation (less than 0.5mm); Next is the rail anchor clamps that adopt the camlock mode, and this anchor clamps can make the door frame distortion when pulling force is big, easily causes anchor clamps to slide in the use, not only loses the effect that drags rail, nor safety.
It is reasonable that the purpose of this utility model provides a kind of compact conformation, in light weight, non-slip, do not damage the self-locking rail anchor clamps of rail face.
The purpose of this utility model is achieved in that these anchor clamps are made up of the left clamping plate of ordinary steel iron, right clamping plate, bearing pin, wedge, cottor pin, safety pin and voussoir stern post.Left and right two clamping plate are oppositely arranged, it is hinged with two clamping plate to penetrate 2 to the 4 pairs of pinned holes in clamping plate middle part with bearing pin, the bearing pin top installs a cottor pin, in case the shotpin axle withdraws from, two clamping plate tops constitute in the wedge-shaped slot that is complementary with the wedge section installs wedge, and installs a safety pin in the pin-and-hole of wedge small end, is extruded by lateral pressure in wedge-shaped slot to prevent wedge, two clamping plate bottoms constitute the down-open recess that matches with the rail head of rail section, in order to contain the rail that is moved.Left and right two clamping plate opposed inside faces middle part respectively is shaped on 2 to 4 pinned holes of raised side, be vertical arrangement and can replace interlock mutually, shank can evenly bear the shearing that clamping plate transmit so that bearing pin therefrom penetrates the back, the front and back end of every clamping plate all is shaped on stiffener, to increase the flexural strength of clamping plate.The plane of wedge is trapezoidal, its upper base width is 40 to 60mm, the width of going to the bottom is 140 to 185mm, highly be 340 to 420mm, the thickness of wedge is 25 to 60mm, and the angle of wedge is 18 ° ± 8 °, the small end of wedge is shaped on a towing pad, in order to install towing pin, hold top to be shaped on a voussoir stern post greatly, impact the stern post wedge with external force and just can lock or release.
The utility model has the advantages that: 1. rational in infrastructure, in light weight, safety again easy and simple to handle.2. adopt self-locking form of structure, do not damage the rail face during operation, non-slip.3. applied range can be used to spur the metal and the non-metallic member of the above long rail of 25m or other analogous shape, can also diffuse at rail stress and make anchor clamps in the facility.
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is the A-A cross section view of the utility model Fig. 1.
Among the figure: 1. left clamping plate; 2, wedge; 3. voussoir stern post; 4. safety pin; 5. right clamping plate; 6. cottor pin, 7. bearing pin.
Left side clamping plate (1) are oppositely arranged with the inboard of right clamping plate (5), make its middle part protrude 2 to 4 pinned holes alternately interlock mutually that medial surface is vertical arrangement, be installed in the pinned hole with bearing pin (7), a left side, right clamping plate are hinged, cottor pin (6) is installed in the pin-and-hole on bearing pin (7) top, in case bearing pin withdraws from, in the wedge-shaped slot that is complementary with the wedge section and the angle of wedge that constitutes at two clamping plate upper openings, install wedge (2), and in the pin-and-hole of wedge front end, install a safety pin (4), in case wedge is ejected wedge-shaped slot under the lateral pressure effect, two clamping plate bottoms constitute the down-open recess that matches with the rail head of rail section, in order to contain the rail that is moved.During operation these anchor clamps are ridden on the rail that is moved, make the under shed of these anchor clamps contain rail head, mention safety pin (4), insert wedge (2), touch its big end and make the clamp rail, connector by tractor is connected with the towing pad of wedge (2) small end, under the dragging of tractor, tractive force affects the rail that is moved, and simultaneously wedge (2) increases with the pushing force that the increasing of tractive force produces, further clamp rail, avoid anchor clamps to skid.After the rail that is moved was dragged to the precalculated position, tractive force stopped and the anchor clamps release, oppositely impacted voussoir stern post (3) again, mentioned safety pin (4) and took out wedge (2), and anchor clamps unload from rail and repeat to use again.
Claims (3)
