Description
Technical field
The present invention relates to clamping mechanism of car dumper shock absorber, particularly relate to tipper counter weight type machinery carriage pressing device oscillating type shock absorber.
Background technology
Tipper unloading system is a kind of high-efficient automatic operating system being widely used in the places such as steel mill, power plant, harbour, for dumping truck.External existing tipper adopts full mechanical counterweight formula carriage pressing device, and counter weight device is wherein hinged, is provided with the impact that shock absorber produces for reducing counterweight during overturning velocity variations in one end of counterweight.External similar devices owing to having larger space, therefore generally adopts the methods such as Long travel rubber buffer to solve displacement problem between opposing oscillatory counterweight and geo-stationary pin at buffering place.
When tipper carriage pressing device of the prior art adopts external counter weight type machinery carriage pressing device, due to space constraint, normal configuration stroke is short and the disc spring buffer gear that elastic force is large, but loop bar and the counterweight of this disc spring buffer gear are structure as a whole, in use can cause structural failure because counterweight swings generation displacement around hinge, bring potential safety hazard.As shown in Figure 4 and Figure 5, when counterweight I 16 around counterweight hinge 17 rotate (angle of rotation be c) time, the loop bar 18 be cemented in described counterweight I 16 will rotate same angle, like this, while spring III 19 pressurized on described loop bar 18, be cemented in described loop bar 18 in described counterweight I 16 by drive described spring III 19 on pin I 20 baffle of porous baffle 21 on slippage (described loop bar 18 creates an angle d relative to initial position), described spring III 19 meeting deflection is stressed simultaneously, everything, capital affects the stressed of structure greatly, cause the damage of the described loop bar 18 be cemented in described counterweight I 16.
Therefore develop a kind of clamping mechanism of car dumper oscillating type shock absorber and become technical barrier urgently to be resolved hurrily.
Summary of the invention
Structural failure can be caused because counterweight swings generation displacement around hinge according in disc spring buffer gear use procedure in the prior art of above-mentioned proposition, bring the technical matters of potential safety hazard, and a kind of clamping mechanism of car dumper oscillating type shock absorber is provided.
The technological means that the present invention adopts is as follows:
A kind of clamping mechanism of car dumper oscillating type shock absorber, comprise pin, counterweight and energy disperser, described counterweight is by the upper articulation of hinge I with described pin, described energy disperser comprises swing arm, spring I, spring II, overhead gage, middle baffle plate, lower baffle plate, described swing arm comprises head and bar portion, be fixedly connected with by described overhead gage between described head with described bar portion, described bar portion is fixedly connected with described lower baffle plate through described middle baffle plate, described spring I is provided with between described overhead gage and described middle baffle plate, described spring II is provided with between described middle baffle plate and described lower baffle plate, described middle baffle plate is by the lower hinge of hinge II with described pin, described middle baffle plate can described hinge II be center of circle rotation, described head is hinged by hinge III and described counterweight,
Under mode of operation, when described counterweight promote described swing arm swing around described hinge I time, described overhead gage compresses described spring I, and realize buffering, meanwhile, described counterweight drives described swing arm generation Angulation changes, thus drives described middle baffle plate to rotate; When described counterweight pulls described swing arm to swing around described hinge I, described lower baffle plate compresses described spring II, and realize buffering, meanwhile, described counterweight drives described swing arm generation Angulation changes, thus drives described middle baffle plate to rotate.
Arrange that to form the two ends that spacing can change hinged only by the rotatable member structure of tension and compression by described hinge III and described hinge II.
The outer wall in described bar portion is socketed with described spring I and described spring II.
Described middle baffle plate is provided with the hole that described swing arm passes.
Principle of work of the present invention is:
After tipper changes to a direction reversal rate, due to the effect of inertia, relatively described pin produces around hinge I trend in relative rotation by described counterweight, due to the promotion of inertia, described counterweight promotes described swing arm by described hinge III, because the described middle baffle plate being hinged on described pin is middle porose, therefore, described swing arm moves axially relatively described pin and described middle baffle plate, because described middle baffle plate 9 is hinged on fixing described pin 1, therefore described spring I 6 is compressed, and realizes buffering.
Due to described hinge II and the existence of described hinge III, and the middle porose existence of described middle baffle plate, the rotation of described counterweight will cause the rotation of described swing arm, like this, because described counterweight is when described hinge I rotates, and the longitudinal travel prolonging described pin produced will not exist, thus solve the lateral stressed problem relative to described swing arm caused by longitudinal travel of the relatively described pin caused because described counterweight is rotated.
When tipper is after the change of other direction reversal rate, described counterweight pulls described swing arm by described hinge III, because the described middle baffle plate being hinged on described pin is middle porose, therefore, described swing arm moves axially relatively described pin and described middle baffle plate, compress described spring II by described lower baffle plate, realize buffering.
The present invention utilizes two ends hinged only by the principle of the rotatable rod member of tension and compression, the bending failure problem that loop bar causes because of transverse force is solved by the rotation of rod member, simultaneously, the middle baffle plate of swing arm, rotatable and hollow, solve again the problem of buffer compression, there is compact conformation reliable, the stressed succinctly advantage such as reasonable.
The present invention extensively can promote in fields such as clamping mechanism of car dumper shock absorbers for the foregoing reasons.
