Description

Gland protects claw Anti-theft buffer stop

Technical field

This utility model belongs to rolling stock technical field of auxiliary equipment, is specifically related to a kind of gland and protects claw and prevent Steal skate.

Background technology

Train runaway refers to that the train stopped on intermediate station circuit slips under external force or self gravitation effect Dynamic and out of control phenomenon, railway using skate anti-slip is necessary means.Skate after train stops Whether being in place whether be related to can be the most anti-slip, meanwhile, skate also to possess antitheft anti-roll Function.Prior art immediate with this utility model is the utility model patent " gland that I has authorized Formula Anti-theft buffer stop " (patent No.: CN201120236096.3), it is not only able to the most anti-slip, and has The standby antitheft anti-function rolled.But find that skate is after using in actual use, it is common that directly put On ground, What is more is thrown away in ground, and this has resulted in skate lock claw and has firmly contacted with ground, causes Damage lock claw, it is therefore necessary to improve.

Utility model content

This utility model solves the technical problem that: provides a kind of gland to protect claw Anti-theft buffer stop, increases and protect pawl Structure, does not the most affect the use of Anti-theft buffer stop lock claw, and when placing Anti-theft buffer stop after using, permissible Protection lock claw avoids it firmly to contact damage lock claw with ground, to adapt to site operation personnel's use habit, and Can ensure that Anti-theft buffer stop is in safe and reliable state all the time.

The technical solution adopted in the utility model: gland protects claw Anti-theft buffer stop, has shoe body and base plate, footwear Body is fixed on base plate, and wallboard is fixed in shoe body, two lock claw by hinge on wallboard, and top Being positioned at shoe body, bottom is positioned at outside shoe body, and the upper end of pusher dog is that square lower end is wedge shape and passes through key axle Being hinged in shoe body, one end of extension spring is fixed in shoe body, and the other end is fixed on pusher dog, makes the upper end of pusher dog Head is positioned at the top of two lock claw upper gap, and lower end is positioned at the bottom of two lock claw upper gap, described group Having depression bar on pawl, the front end of described shoe body is hinged with gland by torsion axis, and the swinging end of gland is positioned at The top of depression bar, described torsion axis is set with torsion spring, and makes the two ends of torsion spring be against the inwall of gland respectively Go up and on base plate, the lower end base plate lateral symmetry of described shoe body is fixed with two backplates, and described backplate offers Bar hole, described lock claw when closure state its lower end part in bar hole.

Further, described backplate is structure as a whole with base plate.

This utility model compared with prior art increases and protects pawl structure, adapts to site operation personnel's use habit, When placing Anti-theft buffer stop after using, lock claw can be protected to avoid it firmly to contact damage lock claw with ground, with really Protect Anti-theft buffer stop and be in safe and reliable state all the time.

Detailed description of the invention

1,2 a kind of embodiment of the present utility model is described below in conjunction with the accompanying drawings.

A kind of gland protects claw Anti-theft buffer stop, has shoe body 1 and base plate 2, and shoe body 1 is by cover plate 13 and two Riser 15 is constituted, and two risers 15 are symmetrical to be fixed on a base plate 2, and cover plate 13 is fixed on two risers 15 Top.Wallboard 9 is fixed in shoe body 1, and two lock claw 5 are hinged on wallboard 9 by U-shaped bearing pin 10, And top is positioned at shoe body 1, bottom is positioned at outside shoe body 1, and the upper end of pusher dog 7 is that square lower end is Wedge shape is also hinged in shoe body 1 by key axle 8, and one end of extension spring 12 is fixed in shoe body 1, another End is fixed on pusher dog 7, makes the upper end of pusher dog 7 be positioned at the top of two lock claw 5 upper gap, under Termination is positioned at the bottom of two lock claw 5 upper gap.There is on described pusher dog 7 depression bar 3, described shoe body 1 Front end be hinged with gland 4 by torsion axis 11, and the swinging end of gland 4 is positioned at the top of depression bar 3, It is set with torsion spring 16 on described torsion axis 11, and makes the two ends of torsion spring 16 be against the inwall of gland 4 respectively Go up and on base plate 2.

Lower end base plate 2 lateral symmetry of described shoe body 1 is fixed with two backplates 18, and described backplate 18 is opened Be provided with bar hole 19, described lock claw 5 when closure state its lower end part in bar hole 19.

The swinging end of described gland 4 bends to right angle and turns 17, and right angle turns and has on the lateral wall of 17 Prevent the limiting plate 6 that gland 4 overturns forward, and limiting plate 6 is positioned at inside cover plate 13 front end face of shoe body 1. The back upper place of the cover plate 13 of described shoe body 1 is provided with portable 14.

During use, railway common key is inserted any one end of key axle 8, rotates clockwise and make pusher dog 7 Upper end be lifted out the top of two lock claw 5 upper gap, lower end wedge shape is rotated up inserting two The bottom of individual lock claw 5 upper gap, promotes two lock claw 5 bottoms to be flared out, then that this practicality is new Type is stuck on rail level, dials lower key, now under the effect of extension spring 12, and pusher dog 7 return and then make lock claw 5 are repositioned to closure state blocks rail's end portion and plays anti-theft function, completes initial erector of the present utility model Make.

When this utility model on pressure wheel, gland 4 overturns lower moulded rod 3 counterclockwise, acts at depression bar 3 Under, the upper end of pusher dog 7 is lifted out the top of two lock claw 5 upper gap, and lower end wedge shape is upwards Rotate the bottom inserting two lock claw 5 upper gap, promote two lock claw 5 bottoms to be flared out, make this Utility model can safety rail joint, now, although lock claw 5 is opened, but this utility model is pressed Can do not take out under wheel, will not lose the most yet.

When wheel is return, gland 4 during return, is arranged on gland 4 under torsion spring 16 rebound effect Limiting plate 6 is blocked by cover plate 13 and can not continue to overturn clockwise, and after gland 4 return, pusher dog 7 is drawing Return under the effect of spring 12, makes two lock claw 5 returns block rail's end portion and plays anti-theft function, now dial The square upper end head of pawl 7 is stuck in the top of two lock claw 5 upper gap, even if manually outwards moving lock claw 5, Lock claw 5 also will not be opened, so that this utility model will not be stolen.

When needs take off this utility model, railway common key is inserted any one end of key axle 8, suitable Clockwise rotates and makes the wedge shape lower end of pusher dog 7 be rotated up inserting under two lock claw 5 upper gap Portion, promotes two lock claw 5 bottoms to be flared out, can take off this utility model and make lock claw 5 be repositioned to close Conjunction state, now lock claw 5 lower end part is in bar hole 19.When placing Theft-proof shoes, backplate 18 lower end is first First contacting to earth, protection lock claw 5 avoids it firmly to contact with ground, is very suitable for site operation personnel and uses, and Can ensure that skate is in normal condition all the time.

The above is only better embodiment of the present utility model, therefore all according to this utility model patent application The equivalence that structure, feature and principle described in Claims scope is done changes or modifies, and is all included in In the range of this utility model patent application claims.
