Background technology
Drop-weight test claims again Falling weight test, and drop-weight test method comprises three kinds at present: first method is that weight is fallen sample from differing heights, asks for the relation of height of fall and sample destructive rate; Second method is fixing weight height and change hammer quality and test, and represents result with trying to achieve corresponding weight quality; The third method is that height of the fall and hammer body quality all change and represent result with the energy of whereabouts weight.
Along with scientific and technical development, going deep into of experimental study, requirement to energy is also more and more higher, hammer body is more and more heavier in test, hoisting depth is also more and more higher, also increasing to the harm of personnel and equipment when test goes wrong, therefore, a kind of safe and reliable hammer body lifting gear that drops hammer of research and development, in warranty test, operating personnel's personal safety has become industry urgent problem.
Utility model content
Technical problem to be solved in the utility model is a kind of hammer body handling device that drops hammer of drop hammer impact testing machine, and hammer body and hammer body handling device connect into an entirety, guarantees that hammer body can not fall automatically.
The technical scheme that the utility model addresses the above problem is as follows:
The hammer body handling device that drops hammer of drop hammer impact testing machine, comprises the lift frame being promoted by pulley, has around the home wire rope on described pulley, and hook cylinder is installed on described lift frame, it is characterized in that:
In described lift frame, rotating shaft is installed, in described rotating shaft, be connected with L shaped hook, one end of described hook is connected with the piston rod of hook cylinder, the other end is the free end for hanging the hammer body that drops hammer, between described hook both sides and lift frame sidewall, be separately installed with block, the upper end of block is fixedly connected with rotating shaft, one side of the relative lift frame of described block has pilot hole, the two ends of described lift frame are affixed cylinder frame all, on described cylinder frame, safety air cylinder is installed, one end of the relative lift frame of described safety air cylinder is connected with latch, the position of the corresponding latch of described lift frame offers through hole, the height of described through hole and pilot hole is mutually concordant.
Further, described block shape is L shaped, and two blocks of hook both sides become mirror image to be symmetrical arranged.
Further again, described L shaped hook is connected by key with rotating shaft with block.
Described rotating shaft is under pulley.
The course of work of the present utility model is, first, lift frame declines, stop motion after lift frame contacts with the hammer body that drops hammer, now link up with cylinder action, one end that L shaped hook connects cylinder piston rod is driven and moves down by piston rod, L shaped hook rotates along rotating shaft, the free end of hook hangs up hammer body, then two safety air cylinders move simultaneously, promoting latch reach inserts through the through hole on lift frame in the pilot hole of block, block is locked, due to block with rotating shaft for being fixedly connected with relation, therefore also rotating shaft cannot be rotated, hammer body is connected with the hammer body handling device that drops hammer of the present utility model, each step of above-mentioned action has pick-up unit, back action does not move, next step action does not allow to carry out, can not fall at any non-artificial situation lower hammer like this, guarantee the security of lifting process, when hammer body is synchronizeed and risen to specified altitude assignment with the hammer body handling device that drops hammer, put well behind position at sample, two safety air cylinder actions, latch is regained, exit the pilot hole of block, then link up with cylinder action, hook is along axle rotation, and hook free end departs from hammer body, hammer body freely falling body, impact specimen, thrusts rear sample and sends outside body, off-test.
Compared with prior art, the beneficial effects of the utility model are:
In the handling process of hammer body, whole actions of the present utility model are all carried out automatically, do not need manual operation, avoid the situation of manual operation error, operating each step remarkable action all can be reported to the police, and ends test, under the fortuitous event such as have a power failure, stop the supple of gas or steam, safety air cylinder can lock hammer body, hammer body is all connected with handling hammer device, can automatically fall, guarantee personal safety in any case.
