CN2257267Y - Theft-proof track-engaging iron shoes - Google Patents

Abstract

The utility model discloses theft-proof track-engaging iron shoes which have the functions of preventing vehicles from running away and being stolen and braking. The theft-proof track-engaging iron shoes is improved on the basis of the advantage of large frictional force of cast steel iron shoes and is added with a locking function. The utility model is characterized in that circular holes are drilled on shoe heads, lock rods pass through the circular holes, both sides of the lock rods are respectively provided with a groove type lock plate which is tightly fixed with nuts, and an unified key is adopted. The outer sides of locking nut are provided with protecting sleeves which can be opened by a special key 9. When the utility model needs to perform a braking action, the lock plates on the both of the two sides can be in the horizontal position through rotating 90 DEG. Meanwhile, the shoe heads are also welded with safe rings so that the utility model has safe and reliable use.

Description

Anti-theft buffer stop

The utility model relates to a kind ofly can effectively prevent wagon running away, has the multifunctional burglary-resistant skate of locking function and brake action again, belongs to and the interactional drg of rail.

Skate is the anti-braking utensil that slips of railway vehicle general-duty, during use skate is placed under the circuit descending wheel on the rail of square steel face, plays the anti-brake action that slips.Because present social security factor, the anti-slip metal shoe of no locking device is stolen losing often, so that cause wagon running away, jeopardizes traffic safety.

The utility model purpose provides a kind of novel anti-theft skate, and it can not only prevent that wagon running away and braking from can prevent also that skate is stolen and losing, can more effective assurance traffic safety.

The purpose of this utility model is achieved in that bores a circular hole on the toe-cap of cast steel skate, a grooved jam plate is respectively pacified in both sides.Simultaneously cut a breach at the skate upper of a shoe place of jam plate to be placed, locking bar is by circular hole, and locking bar one end and jam plate are fixed, and the locking bar other end is a screw thread, with nut movable jam plate is tightened, and is stuck on the rail.Nut peripheral hardware anti-theft protection cover, reaching non-private key can not open, thereby realizes safety and anti-theft feature.When the needs braking function, the both sides jam plate can be turn 90 degrees and be in a horizontal position, can realize braking function.On the toe-cap and be provided with safety link, peace is removed conveniently, meets safety specifications.

Owing to adopt such scheme, not only can prevent wagon running away, can also prevent that skate is stolen and realize the braking function of skate.

The utility model is described in further detail below in conjunction with drawings and Examples;

Fig. 1: multifunction anti-theft skate lateral plan;

Fig. 2: multifunction anti-theft skate birds-eye view;

Fig. 3: 1-1 section-drawing;

Fig. 4 is that the multifunction anti-theft skate is implemented scheme drawing.

Jam plate 1 among the figure, movable jam plate 2, locking nut 3, protecting sleeve 4, lockhole 5, locking bar 6, safety link 7, toe-cap 8, key 9.

Jam plate 1 is fixing with locking bar 6 welding.Put on by lockhole 5 and movable jam plate 2 circular holes, connect, be locked on the rail by locking nut 3.Locking nut 3 peripheral hardware protecting sleeves 4 prevent stolen, and for guaranteeing personal safety, toe-cap 8 heads are provided with safety link 7, remove use for hand-held laying.

When needing anti-the slide, the utility model is placed on the rail face, open jam plate 1 then, jam plate 1 is connected by locking bar 6 with 2, at the fastening locking nut 3 of jam plate 2 one sides, is about to Anti-theft buffer stop and is locked on the rail's end portion.Because locking nut 3 foreign sides establish antitheft protecting sleeve 4, use general purpose tool not open, reach antitheft purpose.Hand-held safety link 7 is easy to use when laying and removing, and can prevent the pressure wheel hand.

According to the anti-direction difference of slipping, locking nut 3 can change of direction: by a sidesway during to opposite side, locking nut 3 taken off remove movable jam plate 2, jam plate 1 together with under 6 groups of the locking bars, is inserted to set up from another point of view after dialling down and gets final product change of direction.

When needs use the skate glancing impact, both sides jam plate 1,2 can be revolved to turn 90 degrees to move to horizontal direction, tighten fixing getting final product with locking nut 3.Because of when can on rail, sliding during skate on the pressure wheel, thereby consume vehicle energy, played brake action.

The utility model is simple in structure, and is safe and reliable, is a kind of later-model self-locking antitheft skate.

Claims (2)

1, a kind of Anti-theft buffer stop is made up of toe-cap (8) and upper of a shoe (10), it is characterized in that having two pairs of jam plates: jam plate (1) and movable jam plate (2); Jam plate (1) is fixing with locking bar (6) welding, and can be through with movable jam plate (2) by the lockhole (5) on cast steel skate toe-cap, is connected by locking nut (3) to be locked on the rail; Locking nut (3) peripheral hardware protecting sleeve (4), protecting sleeve (4) is furnished with private key (9),
