Description

Impact damper detection of dynamic testing machine
Technical field
The present invention relates to a kind of safety technique checkout equipment field, specifically a kind of impact damper detection of dynamic testing machine.
Background technology
Impact damper is the safety device of installing on the equipment that orbits and the vehicle; Make it in operational process; Can effectively absorb the impulsive force that produces because of bump with alleviation when producing collision; Thereby protect and alleviate the damage of this equipment and vehicle effectively, make its effect of the more effective performance of this equipment and vehicle prolong its serviceable life.
Impact damper is widely used in every profession and trades such as metallurgy, mine, machine-building, electric power, harbour, wind-power electricity generation, high ferro.There is nearly various schools of thinkers in the producer that China produces impact damper, and its kind has nearly thousand kinds of specifications and models of tens kinds of patterns such as rubber, spring, polyurethane, hydraulic pressure, compound, damping, liquid gas, air bag, magnet.Only in the hoisting machinery industry; About 30,000 of the hoisting devices of the annual production of China at present; About 5,000,000 of original hoisting devices; Wherein hoisting device deadweight is several more than 90% for the equipment recoverable amount number below the 100t accounts for the hoisting device platform, and the hoisting device deadweight is the above less than 10% of 100t, and annual used number of buffers (comprising the overhaul of the equipments replacing) is more than 1,000,000.In the recent period, along with the fast development of high ferro, subway, wind power plant, impact damper has also obtained using widely on these application apparatuss as the important safety protective device.
Cushion effect, buffering energy, cushion stroke are to weigh three big important indicators of bumper property, and the True Data that wants to obtain it must detect completion by type approval test.China is responsible for the impact damper testing by Beijing hoisting machinery research institute quality supervision inspection center at present; This center does not have the dynamic impulsion testing table now; Can only accomplish testing with static hydraulic dynamometer, and the envelope test machine can not obtain the main performance index of impact damper really, especially hydraulic pressure and hydro-pneumatic buffer; Because of its exclusive energy conversion mode, make the envelope test machine can't collect the performance data of " buffer capacity " and " cushion effect " these two keys at all.
At present.The reference data of just putting in order that producer provided of our domestic all production impact dampers through Static Detection data computation and empirical data; Use department also can only be by performance index that factory provided and the design Selection impact damper; Do neither science like this; The performance of performance impact damper that can not be true and reliable; Therefore brought insecurity and the unreliability of using equipment, device damage and the personnel casualty accidents that therefore cause every year happen occasionally, and have buried great hidden danger for national wealth and personnel's life security.
So being China, design, research, reliable, the truly feasible impact damper detection of dynamic testing machine of manufacturing science be badly in need of the big event problem that solves at present.
Summary of the invention
The purpose of this invention is to provide a kind of impact damper detection of dynamic testing machine.
The objective of the invention is to realize like this: it includes Load-bearing rail, has the test specimen mounting base of test specimen mounting seat and load sensor; It is characterized in that: fixed bumper test specimen on the described test specimen mounting seat; Load sensor is arranged between test specimen mounting seat and the test specimen mounting base, is provided with distance measuring sensor and tachogenerator group along the horizontal level of impact damper test specimen outer face; Load-bearing rail is provided with all the load test car and the traction control car of band unhook head; Load-bearing rail end in traction control car one side is provided with the traction power group; This traction power group is connected with traction stake on the traction control car through traction steel rope of cable, on the traction control car, also being provided with unhook and moving handle and unhook controller; Described load test car includes the chassis structure beam; The chassis structure beam of traction control car far-end is provided with the load bearing support; This load bearing support arranged outside has vertical level and the test relative with impact damper test specimen outer face to impact workplace; Load bearing support top is provided with main bearing, and main bearing is connected with the load bucket, and the chassis structure beam in both sides, load bucket middle part is provided with and promotes the gear set framework; Promote the gear set framework and be provided with the lifting gear set, promote the corresponding Load-bearing rail of gear set and be provided with stationary rack; Be provided with and promote in load bucket both sides gear set meshing and with load bucket and the hinged transmission arc rack of chassis structure beam.
For the whereabouts impulse force of cushion load bucket, avoid causing mechanical damage, the chassis structure beam of load bucket downside to be provided with load bucket load-bearing bullet pad with the direct bump of chassis structure beam.
Principle of work of the present invention is: described load inspection vehicle is to be driven by the goods charging bucket drop energy that loads on the car; Himself quality is to join the vehicle body deadweight; The test set-up procedure is the storage that transfers the power institute energy requirement that drives the load inspection vehicle with tractive force to; Discharge the back and move, accomplish of the testing of impact damper detection of dynamic testing machine test specimen with energy stored driving load inspection vehicle on the car.
The present invention has following characteristics:
1.. utilizing fixedly, tooth bar ﹑ promotes the firm type connection that gear makes up ﹑ load bucket transmission arc rack; Convert less horizontal drag force the big potential energy of load bucket into, for the load test car has stored big quality load body at the fair speed necessary energy condition that moves;
2.. after the unhook; The load bucket that has stored big potential energy promotes gear combination ﹑ stationary rack through load bucket transmission curved tooth bar ﹑ again provides the ability that in short distance, accelerates to required movement velocity for the load test car, has avoided the weakness of the required high-power drive power source of big quality load test car;
3.. made full use of the load thing and the quality of load test car self in the load bucket that is contained on the load test car, formed the required big quality load of detection of dynamic jointly, minimizing testing machine material therefor has reduced equipment cost;
4.. load capacity in the adjustment load bucket and the distance that the load test car moves on stationary rack, the movement velocity that can change the load test car easily with clash into quality, the different technologies condition when satisfying dissimilar test specimen detection of dynamic;
5.. the load test car need not to be equipped with other mechanical hook-up and opertaing device, has avoided the disadvantage that causes control device to damage easily because of impact process.
The present invention can truly gather out each item main performance data of impact damper; For orbital motion equipment, hoisting machinery and vehicle more safety device such as scientific and effective, reasonable configuration impact damper scientific basis is provided, avoid generation because of inaccurate national wealth that causes of bumper property index and personnel casualty accidents.
