Abstract

Provided is a railway cross hooking lock setting for a closed switch rail, comprising a fixed hook, a screw connected to the fixed hook, and a movable card track base sleeving the screw. The fixed hook and a hook disposed on the movable card track base are arranged inwardly. The screw is provided with a long groove along the axial direction. An inner hole of the movable card track base is provided with a boss matching with the long groove, and thereby when the movable card track base sleeves the screw, the boss is in the long groove and is capable of moving back and forth without changing directions. The screw is sleeved by a handwheel nut disposed at the outer side of the movable card track base. The movable card track base is provided with a lockhole, and circular holes are evenly distributed in the handwheel nut. When the handwheel nut is being rotated, one of the circular holes can be at a position, corresponding to the lockhole in the movable card track base. The railway cross hooking lock setting for a closed switch rail is advantageous in that the handwheel nut can be locked with the movable card track base by means of a common padlock; locking function and loosening function are both possessed; structure is simple, operation is convenient, dismounting is fast and use is safe and reliable.

Description

Closed switch rail is used the track switch hook lock device

Technical field

The utility model relates to the general track switch hook lock device of a kind of closed switch rail.

Background technology

With the immediate prior art of the utility model is " the locking hood type closed switch rail is with track switch hook lock device (ZL200720079172.8) " utility model patent; Though this patent has solved the track switch hook lock device and has been prone to loosening and does not have problem such as anti-joyride device, has drawbacks such as complex structure, productive costs height, unstable properties.Therefore be necessary to improve.

The utility model content

The purpose of the utility model is to provide a kind of closed switch rail general track switch hook lock device, solves the problems referred to above that existing track switch hook lock device exists effectively.

The technical scheme that the utility model adopts: the general track switch hook lock device of a kind of closed switch rail; Comprise stay hook, with stay hook bonded assembly screw rod and be sleeved on the active card rail chair on the screw rod; Grab on said stay hook and the active card rail chair is provided with inwardly; Have long recess on the said screw rod vertically, have the boss suitable on the endoporus of said active card rail chair, make the active card rail chair be sleeved on the screw rod rear boss and be arranged in long recess and can move forward and backward with long recess; Be set with hand wheel nut on the said screw rod, and hand wheel nut is positioned at the outside of active card rail chair; Have lockhole on the said active card rail chair, be uniformly distributed with circular hole on the hand wheel nut, and one of them circular hole can be corresponding with the lockhole on the active card rail chair when rotating hand wheel nut.

Further, said hand wheel nut outer end has chuck, and is uniformly distributed with the draw-in groove of outside protrusion on the chuck outer rim.

Further, the outer end of said screw rod is set with handlebar grips cover.

Further, have two grabs up and down on the said stay hook.

Further, be uniformly distributed with 16 circular holes on the said hand wheel nut, chuck is uniformly distributed with 4 draw-in grooves.

Advantage that the utility model compared with prior art has and effect:

1, the active card rail chair of the utility model moves forward and backward Shi Buhui and on screw rod, rotates, and is easy to use, high efficiency;

2, the utility model is through the improvement to hand wheel nut and active card rail chair lock; Use common padlock can hand wheel nut and active card rail chair be locked together; Not only has the locking function; And have the function of loosening, particularly have simple in structure, easy to operate, fast assembling-disassembling, advantage such as safe and reliable.

Description of drawings

Fig. 2 is the active card rail chair structural representation of the utility model;

Fig. 3 is the handwheel running condition scheme drawing of the utility model.

The specific embodiment

A kind of embodiment of the utility model is described below in conjunction with accompanying

drawing

1,2,3.

A kind of closed switch rail is used the track switch hook lock device; Comprise stay hook 1, with stay hook 1 bonded assembly screw rod 2 and be sleeved on the active card rail chair 3 on the screw rod 2; Grab on said stay hook 1 and the active card rail chair 3 is provided with inwardly; Has long recess 5 vertically on the said screw rod 2; Have the boss 7 suitable on the endoporus of said active card rail chair 3, make active card rail chair 3 be sleeved on the screw rod 2 rear boss 7 and be arranged in long recess 5 and can move forward and backward, guaranteed that active card rail chair 3 moves forward and backward Shi Buhui and on screw rod 2, rotates with long recess 5.Easy to use, high efficiency.

Be set with hand wheel nut 4 on the said screw rod 2, and hand wheel nut 4 is positioned at the outside of active card rail chair 3; Have lockhole 8 on the said active card rail chair 3, be uniformly distributed with 16 circular holes 9 on the hand wheel nut 4, and one of them circular hole 9 can be corresponding with the lockhole 8 on the active card rail chair 3 when tightening to rotate hand wheel nut 4.Use common padlock to pass lockhole 8 and circular hole 9 can lock together hand wheel nut and active card rail chair, not only have the locking function, and have the function of loosening.

Said hand wheel nut 4 outer ends have chuck 11, and are uniformly distributed with 4 outwards draw-in grooves 10 of protrusion on chuck 11 outer rims.Four draw-in grooves 10 not only can make things convenient for 12 operations of hook spanner fastening in different angles; And outwards the structure of protrusion has prevented that hook spanner 12 and chuck 11 from interfering each other, guarantees that hook spanner 12 and draw-in groove 10 better coincide, and guarantees fastening stressed steady; Reliably, non-slip.

The outer end of said screw rod 2 is set with handlebar grips cover 6.Handlebar grips cover 6 adopts elastomeric material, and appearance is provided with anti-skidding salient point, and winter, hand was not frozen in operation.

Have two grabs up and down on the said stay hook 1.The grab of top can be stuck in 60# rail, the 75# rail tongue flange of rail, and the grab of below can be stuck in 43# rail, the 50# rail tongue flange of rail.

Method of application: at first rotate plum blossom hand wheel nut 4, active card rail chair 3 is moved to the handgrip position, then hook lock device is passed from the stock rail bottom; Stay hook 1 hooks the closed switch rail flange of rail; Active card rail chair 3 is hooked the stock rail flange of rail, adopt hand then earlier, tighten to tightening state with hook spanner 12 at last through rotation plum blossom hand wheel nut 4; Aim at lockhole 8 and circular hole 9 at last, use padlock that active card rail chair 3 and plum blossom handwheel 4 lockings are got final product.Earlier open padlock during release, adopt hook spanner 12 left-hand revolution plum blossom hand wheel nuts 4 to retreat then plum blossom
