Further, between described columnar part and hammer ram belt wheel, be provided with the safety component that prevents that columnar part from coming off from slideway, play the effect of safe falling-prevention.
Further, described safety component is for being laterally through the pin in columnar part end.
Further, described safety component is the block that is arranged on columnar part end.
Further, described flexible member is the extension spring element being arranged between eccentric block and slideway.
Further, described flexible member be nested with on columnar part and be arranged on eccentric block and slideway between extension spring element.
Further, described flexible member is the compression spring element being arranged between columnar part and slideway.
Further, described driver part is a kind of in motor or motor.
The invention has the beneficial effects as follows:
Under static state, be subject to the pretension of flexible member, can so that eccentric block near place, hammer ram belt wheel axle center, after starting, due to the progressively raising of velocity of rotation, eccentric block overcomes the damping force of flexible member and does centrifugal motion, until reach duty, now eccentric block relies on flexible member and safety component to support, and because eccentric block is now positioned at away from hammer ram belt wheel axle center, so hammer ram can be taken up, play the effect identical with common frog hammer.In like manner, this kind of structure also can shorten dwell time.
The eccentric block relating in present technique is movably, when rammer starts due to from the centre of gyration close to, the centrifugal force of generation is less, after starting, eccentric block is away from the centre of gyration, until the requirement of centrifugal force while reaching work, by the quick startup of this process implementation rammer.So the invention solves the time length in frog hammer startup and stopped process, the high problem that consumes energy, and safer, steady.

The specific embodiment
Embodiment mono-, as shown in Figures 1 to 4.
The frog hammer starting fast is mainly comprised of hammer ram 1, eccentric block 2, hammer ram belt wheel 3, belt 4, belt wheel 5 and motor 7.Wherein, handrail 8 and motor 7 are arranged on base plate 9, and base plate is the support component contacting with ground, by belt, are connected with belt wheel 5, and belt wheel 5 is connected with hammer ram belt wheel 3 by belt, realize the rotation that drives hammer ram belt wheel.
Described hammer ram 1 is connected by circular shaft 91 pivot joints with base plate 9, and the axle center of circular shaft 91 and belt wheel coaxially arrange, and hammer ram belt wheel 3 is arranged on the upside of hammer ram, and these are all prior aries.Improvements are:
