Abstract
The utility model provides an elastic pin lifting mechanism of a car puller; an oil cylinder cranked lever is connected with a lock pin through a tension spring with an elastic modulus of 1000N/m, that is, an energy storage device is additionally arranged between an oil cylinder and a pin lifting device; once a hydraulic system acts precociously or hysteretically, the tension spring automatically stores energy; after a mechanical device runs in place, the running reliability degree of equipment is improved, the phenomenon that pin shaft blocking and mechanical damage arising from pin lifting action and inconsistent actions of a railway carriage and the puller affect the production can be avoided, the service life of the hydraulic oil cylinder is prolonged, and the equipment failure rate is remarkably reduced.
Description
Technical field
The utility model belongs to the mechanical equipment field, and particularly a kind of car puller elasticity is carried pin mechanism.
Background technology
At present, tipper unloading system is made up of car puller and tipper substantially, and after tipper rotated to ready position, car puller to the position location, sent instruction by control system with the railway carriage traction, carries the pin cylinder action, and the lock hook pin is proposed.Pluck and collude after action finishes, car puller is return the home position, carries out next link operation and prepares.
But carry pin mechanism at present following defective arranged: when railway carriage in place static after, system sends to be carried pin and plucks and collude instruction, drawing oil cylinder begins action.But this moment, because the signal of system acquisition can not determine that for the ct-off signal that the car puller traveling drives railway carriage and car puller stop to slide fully, the lock hook pin of this moment is because of being clamped and can not propose by eave tile mechanism.The pin mechanism of carrying of this moment is in overload, and hydraulic efficiency pressure system overflow protection is opened.Owing to the regular overload work of entire mechanism, directly shortened the service life of equipment (comprising the railway carriage hook), stopping accident happens occasionally.And original design adopts when carrying pin is that Driven by Hydraulic Cylinder curved bar mechanism drives steel rope and mentions bearing pin, because the steel cable crank motion, operating cycles is very short, very easily causes physical damage, and influence is produced.
Summary of the invention
It is a kind of simple in structure, safe and practical that the purpose of this utility model is to provide, but the abatement apparatus overload running prolongs service life of equipment, reduces the car puller elasticity of accident rate and carry pin mechanism.
The technology solution that the utility model is taked is:
A kind of car puller elasticity is carried pin mechanism, it is characterized in that, adopts extension spring to be connected between oil cylinder curved bar and lock hook pin.
The modulus of elasticity of described extension spring is 1000N/m.
The beneficial effects of the utility model are:
Because the utility model is replaced by spring traction bearing pin with former steel cable towing pin axle, be equivalent at oil cylinder and carry and increased an energy storage equipment between the pin assembly, in case the hydraulic efficiency pressure system action takes place leading or lags behind, the automatic stored energy of extension spring, by the time carrying pin mechanism after mechanical device operation puts in place will work automatically, improve the degree of reliability of equipment operation.Stop owing to the phenomenon that bearing pin is stuck, physical damage influences production often appears in the exercise not harmony of carrying pin action and railway carriage and car puller, improve the service life of hydraulic ram, equipment failure rate significantly reduces.
Description of drawings
Accompanying drawing is carried the pin mechanism scheme drawing for car puller elasticity.
Among the figure: eave tile mechanism 1, lock hook pin 2, extension spring 3, curved bar 4, oil cylinder 5.
The specific embodiment
By accompanying drawing as seen, the main effect of lock hook pin 2 is that attaching parts with eave tile mechanism 1 is locked in the eave tile mechanism 1.Carry pin mechanism and comprise curved bar 4, oil cylinder 5 and the attaching parts that lifts lock hook pin 2.The utility model adopts modulus of elasticity between curved bar 4 bar heads and lock hook pin 2 be that the extension spring 3 of 1000N/m is connected.
After railway carriage was in place, system sent instruction, and oil cylinder 5 and curved bar 4 are carried out and proposed the pin action.As when running into lock hook pin 2 the jam phenomenons taking place, extension spring 3 stretches, and curved bar 4 is unaffected with oil cylinder 5 actions; When railway carriage and car puller structure in place fully static after, lock hook pin 2 jam phenomenons automatically terminate, extension spring 3 proposes lock hook pin 2 automatically.
Claims (2)
1. a car puller elasticity is carried pin mechanism, it is characterized in that, adopts extension spring to be connected between oil cylinder curved bar and lock hook pin.
2. car puller elasticity according to claim 1 is carried pin mechanism, it is characterized in that, the modulus of elasticity of described extension spring is 1000N/m.
