Abstract

The utility model discloses a self-locking scotch iron shoe, which is suitable for scotching vehicles on a railway special line and preventing accidental slides and collision. Due to the structure is formed by the way that a self-locking antitheft device is added on the basis of a common use iron shoe, the utility model has the functions of theft prevention, and convenient unlocking and lock, the utility model has the advantages of convenient use and self-locking safety, and the speed of putting on the iron shoes is high.

Description

The self-locking type scotch iron shoe

The utility model relates to a kind of being applicable to and only takes turns, prevents unexpected runaway when railway special line comprises the stoppage of vehicle of loading and unloading track, and the skate of collision accident takes place, and belongs to the device that guarantees railway shunting safety.

At present, the scotch iron shoe that the China railways private siding uses mainly contains two kinds: a kind of common skate that does not have anti-theft feature, thereby lose serious; Another kind has anti-theft feature, and it is to skate locking and release by private key.This skate inconvenient operation, last footwear speed is slow, influences operation and personal safety.

The purpose of this utility model provides a kind of self-locking, antitheft scotch iron shoe.It is a kind of can be antitheft again can be easy to use, last footwear speed agility, safe and reliable self-locking skate.

The utility model technical solution is for to improve common skate; Increase by a cover lock core structure and establish one group of torsion spring.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

View when Fig. 2 is the utility model locking;

AA cutaway view when Fig. 3 is the utility model locking;

State BB cutaway view when Fig. 5 is the utility model release.

The utility model comprises that weldering is 1, two cant board 2 of a base plate of one, cover plate 3, and 4 four footing 5 of swash plate, handle 6 and key 20, the width of base plate 1 is consistent and closely connected with it with the tread face width; It is characterized in that: respectively open two pairs of holes on the cant board 2: stud with a pair of and garden eyelet welding lining 12 in the hole, a pair of garden of the first half, lock core 9 is housed in the lining 12 in one; Another is a square type locking rod 16 to a pair of section is housed in the slot 19, is welded with fulcrum pin 18 on the cant board 2, and locking rod 16 is installed on the fulcrum pin 18, and the support 14 of torsion spring 13 is welded on the lining 12; Lock core 9 is the garden cylindricality, and its two ends are provided with triangle key door 7, and one face down bonding has buting iron 10 at lock core 9 middle parts, and corresponding opposite side is welded with dead bolt 11, and lock core 9 can rotate in lining 12 flexibly.Be welded with the support 14 of torsion spring 13 on cant board inner covering 12, torsion spring 13 hangs on the support 14.The upper end of torsion spring 13 is not on buting iron 10, and its lower end is made and colluded shape and do not hang on the movable axis 15, and movable axis 15 is loaded in the shape hole, ellipse garden 17 of locking rod 16 and can moves flexibly.Locking rod 16 is the rectangle steel casting for its basal area of J type, and hole, last shoulder garden is the mounting hole 8 of fulcrum pin 18, fulcrum pin 18 and cant board 2 welding.Base plate 1 width is consistent with railway track face width degree, and can be closely connected on rail level.5 left and right sides positioning actions of footing, two locking rods 16 bottom minimum width therebetween should be slightly larger than the web of the rail, less than the rail head width, so that can be fixed on easily on the rail during locking, and block the web of the rail securely, when two locking rods 16 open minimum angles α greater than 30 ° so that take out skate.

During locking skate is placed on the railway rail, inwardly touch locking rod 16 outsides with hand, raise the certain level position with locking rod 16 upper ends, dead bolt 11 is borrowed torsion spring 13 elastic force, dead bolt 11 bottoms are caught on two locking rods, 16 connecting end movable axis, 15 belows, then are locking states, because locking rod 16 lower ends are colluded the waist that snaps in railway rail and made skate be securely fixed in the purpose that reaches theftproof self-locking on the rail.Because the auto-lock function that locks without key 20, to go up footwear convenient, quick, safe and reliable, be particularly conducive to operating personnel under the car.Demonstrate preceence and value of service when not enough and operation is busy in illuminance more.

The utility model lock core 9 both sides are equipped with key door 7 again, the dead bolt 11 that column type lock core 9 is rotated to an angle on the lock core body by private key 20 leaves movable axis 15, because torsion spring 13 1 ends are not on the buting iron 10 of lock core 9, the other end does not hang on the movable axis 15, because torsion spring 13 extensions are sent away movable axis 15 and are moved at shape hole, locking rod 16 ellipse garden 17 interior orientations, drive locking rod 16 and open the taking-up skate.

The utility model flexible movements, skate is taken off in one-time-reach-place.

The utility model is a kind of simple in structure, and cost is low, and goes up footwear speed agility, and is easy to use, not only antitheft but also can safe and reliable scotch iron shoe.
