The railroad switch hook locker has the advantages that the structure is simple, the operation is quick and convenient, the outer appearance is artistic, the intensity is good, the weight is light, the locker is secure and reliable, and has anti-theft performance.

Description

The track switch hook lock device

Technical field

The utility model belongs to hook lock device, specially refers to a kind of hook lock device that is applicable to railway switch.

Background technology

At present, when railway switch is locked, employing be screw mandrel hook type hook lock device.By the mode that screws nut track switch is locked.Though this hook type screw mandrel hook lock device is made simple, its manufacturing is coarse, heavy, the locking time slow, poor performance; Also have a kind of hook lock device,, utilize unidirectional lock iron locking and band tooth bar slide bar to realize quick dispatch by ratchet control lock iron with tooth bar slide bar, ratchet.Though its use is convenient, complex manufacturing technology, cost height; The another kind of hook lock device of being made up of lock dog and locking mechanism is though that its lock dog can be fit to track switch and its use cost of various interior types is low, owing to the gravity that hook lock device bore that the rail model difference of railway is required are also different with pulling force.Thereby the requirement to gravity of hook lock device own and pulling force is also different.So it is not effectively used.

Summary of the invention

The purpose of this utility model with regard to be to provide in order to address the above problem a kind of make simple, swift and convenient to operate, performance is strong, intensity good, weight is light, have the quick hook lock device of theftproof.

The purpose of this utility model is to realize like this.Described track switch hook lock device comprises the preceding hook 1 of hook lock device, hook lock device body circular arc 2, screw rod 3, chuck 4, locking plate 5, goes up lockhole 6, lock pin 7, locknut 8.Its design feature is: hook lock device adopts the thick steel plate of Q235 material 25-30mm to make.The spacing 9 of hook 1 is identical with the spacing 10 of hook lock device body circular arc 2 before the hook lock device.Hook 1 hook portion shape before the hook lock device, 2 transition of hook lock device body circular arc are accurate, slick and sly, thereby can eliminate the hidden danger that there are crackle in former hot forging, cast member, because hook lock device body circular arc 2 can bear bigger pulling force through calculating accurately and passing through and test.Prove that through experimental verification P43 type hook lock device can bear 56KN; P50 type hook lock device can bear 68KN; P60 type hook lock device can bear 85KN; P75 type hook lock device can bear 100KN.Turning rectangular thread on screw rod 3.The screw rod 3 of the other end of hook 1 is provided with chuck 4 before the hook lock device, the center on the chuck 4 be provided with the corresponding centre bore of the diameter of screw rod 3 and making around it that four distances equate, size is identical on lockhole 6.In the chuck back is locking plate 5, with the centre bore of locking plate 5 be lathed with screw rod 3 on rectangular thread corresponding in rectangular thread, and on making around it that 12 distances equate, size is identical lockhole 6.Block stock rail rail 11 feather edges with chuck, locking plate 5 can screw locking plate 5 rapidly owing to be rectangular thread.In locking plate 5 back are locknuts 8, with the endoporus of locknut 8 be lathed with screw rod 3 on rectangular thread corresponding in rectangular thread, same because locknut 8 is rectangular threads, can carry on the back tight locknut 8 rapidly; Its shock-proof check performance improves greatly simultaneously.Last lockhole 6 on the locking plate 5 can align naturally with last lockhole 6 on the chuck 4, and lockhole 6 in the formation.Can pin lock pin on the last lockhole 67.Lock pin 7 has antitheft and prevents other people maloperation behavior.Component of the present utility model are handled through zinc-plated secondary passivity, strengthen rustless property, increase the service life.The utility model can be made (P43, P50, P60, P75) different model according to the model (43#, 50#, 60#, 75#) of railway track.

The beneficial effects of the utility model: the utility model is simple in structure, swift and convenient to operate, aesthetic in appearance, intensity is good, weight is light, safe and reliable, have a theftproof.
