Among the prior art, the purpose that the pile sinking was reached in vibrations about the vibratory hammer all realized through the eccentric wheel band pulley, the vibratory hammer is at the operation in-process, need to realize becoming the stake at center pouring concrete, if the central through-hole of vibratory hammer is less, then the difficult tamp of concrete makes the pile body structure after the stake loose, and on the other hand, the hammer block of present vibratory hammer all is through the screw fixation on the vibrating bin, in long-time use, the screw head is piled up cement easily and is solidified and cause the screw to dismantle inconveniently.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a become stake effect better and be connected more convenient cavity vibratory hammer between hammer block and the vibration case.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a cavity vibratory hammer, is including the damping roof beam, vibration case and the hammer block of mutually supporting, its characterized in that, the center of hammer block is through-type through-hole structure, the damping roof beam with the vibration case all with the through-hole intercommunication at hammer block center, the upper end both sides welded fastening of hammer block has the connecting plate, the both sides of connecting plate are provided with the connection lug of integral type, the below both sides of vibration case articulate have with be connected lug complex clamping jaw, every wear to be equipped with bolt and bolt overcoat on the clamping jaw and be equipped with the spring.

In this cavity vibratory hammer, the concrete is poured into from damping roof beam top opening part, flows through vibration case and hammer block through-hole in proper order and gets into underground and becomes the stake, and wherein the effect of vibration case is for driving the vibrations of hammer block, and the damping roof beam is used for preventing the vibrations transmission that the vibration case produced upwards the utility model discloses in, the hammer block links firmly each other through the clamping jaw of connecting plate cooperation vibration case below, and its principle makes the clamping jaw open when the bolt tightening on the clamping jaw simultaneously for the extrusion spring, and the hammer block is put into vibration case below and is the position of connecting lug and corresponds with the clamping jaw, and later not hard up bolt makes the spring rise to open the elasticity through the spring closed with the clamping jaw, connects the lug and just blocks and locates in the clamping jaw from forming the reciprocal anchorage.

In the hollow vibration hammer, a plurality of vibration reduction springs are symmetrically arranged on two sides of the vibration reduction beam and the vibration box, and a plurality of buffer springs are arranged between the vibration box and the clamping jaw.

In the hollow vibration hammer, the damping springs and the buffer springs are the same in number, are in one-to-one correspondence in position, and are located on the same axis.

In the hollow vibratory hammer described above, the number of the damper springs and the damper springs is 3 on each side.

In foretell hollow vibration hammer, the top of damping roof beam is provided with the funnel, the funnel pass through outside floor and damping roof beam up end welded fastening, the funnel be semicircle platform form.

Compared with the prior art, the hollow vibration hammer has the following advantages:

1. the hammer body is fixed with the vibration box through the clamping jaw and the connecting plate, so that the hammer body is more convenient to assemble, disassemble and position;

2. the central through hole of the hammer body is directly communicated with the vibration box and the vibration damping beam, so that the feeding is more convenient and faster, and the pile forming effect is good.
