Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
A kind of Hydraulic clay gun hanging mechanism comprises clay extruded mechanism 1, saddle 2, pivoted arm 3, bearing 4, upper cover 5 and snubber 7.Upper cover 5 is arranged on saddle 2 by 10.9 grades of high-strength bolts 6 of 8 M24 × 80.Past installs the bolt 6 of upper cover 5 and usually produces the loosening phenomenon even ruptured, and is often considered to that repeated stress failure causes.Therefore always look for reason from fatigue strength, in fact, high-strength bolt 6 fatigue strength is large that we cannot imagine, bolt 6 is not in use rupture because of overtired.Not clear and definite bolt 6 fracture cause, needs to analyze from multi-angle:
One, bolt 6 ruptures is not tensile strength due to bolt 6:
For 8.8 of M20 × 80 grades of high-strength bolts 6, its weight only has 0.2 kilogram, and its lowest pull load is 20 tons, up to 100,000 times of its own wt, generally, we only with its parts of fastening 20 kilograms, also can only use the thousandth of its maximum capacity.Even if the effect of other power in equipment, thousand times that also can not break through component weight, therefore the tensile strength of threaded fastener is enough, can not damage because of the insufficient strength of bolt 6.And the tensile strength of 10.9 grades of high-strength bolts 6 of M24 × 80 is far longer than this especially in hanging mechanism, therefore the source of damage is not because tensile strength is inadequate.
Two, the fracture of bolt 6 is not the fatigue strength due to bolt 6:
Threaded fastener only needs can loosen for 100 times in transverse-vibration pine nut is tested, and needs repeatedly to vibrate 1,000,000 times in fatigue strength experiment.In other words, threaded fastener using ten thousand of its fatigue strength/ namely loosened for the moment, we only employ its large ability ten thousand/, loosening of threaded fastener neither because of bolt 6 fatigue strength thus.
Three, the true cause that threaded fastener damages is subject to the bolt 6 that radial impact causes to loosen:
After threaded fastener loosens, be subject to impact and can produce huge kinetic energy, this huge kinetic energy directly acts on fastening piece and equipment, causes fastening piece to damage, and after fastening piece damages, equipment cannot work under normal state, causes structure deteriorate further.If be subject to the fastening piece of responsive to axial force, screw thread is destroyed, and bolt 6 is pulled off.If be subject to the fastening piece of radial force effect, bolt 6 is cut off, and bolt 6 hole is broken into ellipse.
Conclusion: analyzed as can be seen from above, the basic reason that hanging mechanism bolt 6 ruptures is that bolt 6 loosens again because the impact being subject to radial force causes because bolt 6 loosens.So the way of head it off is just how to reduce the radial impact power that bolt 6 is subject to.
Saddle 2 is fixed with 10.9 grades of high-strength bolts 6 of upper cover 5 by 8 M24 × 80, these 8 bolts 6 are except bearing the weight of saddle 2 and clay extruded mechanism 1, when clay extruded mechanism 1 operates, surging force suffered by whole hanging mechanism is also used on bolt 6, make bolt 6 be subject to very large shearing force, especially when blocking up, big gun mouth and mud overlap severe impact and produce great shearing force and surging force to bolt 6.
In addition, unexpected pause during owing to entering big gun and moving back big gun excessive velocities, advance and retreat big gun, the kinetic energy that the inertia that all saddle 2 and clay extruded mechanism 1 weight can be produced and impact produce all is delivered on bolt 6, causes loosening of these 8 bolts 6.Bolt 6 is once loosen, and clay extruded mechanism 1 will swing, and what make bolt 6 loosens aggravation further, and hanging mechanism upper cover 5 and saddle 2 gap increase, and saddle 2 and clay extruded mechanism 1 sink.If there is no Timeliness coverage, because of shearing force and instant impact, joint bolt 6 certainly will be cut off, finally cause the accident that saddle 2 and clay extruded mechanism 1 entirety are fallen.
Solution:
As shown in Figure 1 and Figure 2, have found the very crux of problem, after having fully taken into account each side factor, the Hydraulic clay gun hanging mechanism that the utility model provides has been welded with key on saddle 2 contact surface with upper cover 5, with the keyway 8 contact surface of saddle 2 being provided with key and matching below upper cover 5.Key is utilized to be subject to radial surging force to absorb bolt 6.Certainly also key can be welded on upper cover 5, and keyway 8 is located on saddle 2.When being subject to radial impact, most surging force is all absorbed by key, the bolt 6 effectively protected.Impact to absorb better and increase work-ing life of key, key length direction is set to consistent with the radial impact force direction that described Hydraulic clay gun hanging mechanism is subject to.And two keys matched and keyway 8 are set, the centrosymmetry of their relatively described Hydraulic clay gun hanging mechanisms.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
