Abstract

The utility model discloses a vibration damping device for vibration pile hammers. 12 springs (2) provided with a guide mechanism and a supporting base mechanism are arranged between an upper crossbeam (1), the left and right spring seats (6) (8') of a pile hammer box body (5), and on the lower part of the spring seats (6) (8); The vibration damping device is additionally provided with four springs, which enhances elastic bearing capacity, overcomes the defects that the elastic bearing capacity of original devices is deficient so as to make the vibration damping device adapt to working in the pile driving construction of hard soil, meantime, enlarges bearing area for intensifying the stability of the whole device, and effectively converts kinetic energy to potential energy to save energy.

Description

Vibration pile driving hammer shock absorbing device
The utility model is the improvement invention about vibropiling hammer damping device.
The damping device of existing known vibropiling hammer is two-way single vibrational structure, between the left and right sides spring base of top rail and pile monkey casing side direction, 4 springs respectively are housed below the spring base of the left and right sides, totally 8 springs, utilize elastic reaction to extenuate impact force, and electronic rotational kinetic energy is converted into spring potential energy, reach vibropiling.Said apparatus particularly runs into firm hard formation when the operation of pressurization pile sinking if in the construction of pan soil matter, and the spring holding capacity is not enough, and spring is compressed into and tight position, and spring has lost cushioning effect, then cause the motor overload heating, even burn.
In view of the problem of existing known technology, the purpose of this utility model aims to provide a kind of damping device that has big spring bearing capacity more and improve the vibropiling hammer of resistance to overturning.
The utility model is achieved in that under the top rail and between the left and right spring base of the side direction of pile monkey casing, and 4 original springs are increased to 6, is symmetrically distributed on the left and right spring base; Under left and right spring base, also former 4 springs are increased to 6 simultaneously, bilateral symmetry distributes.Spring is 12 altogether like this, and has guiding and stand apparatus at head.
The utility model has been compared following advantage with former vibropiling hammer damping device: the one, strengthened elastic carrier power, and can adapt to operate as normal in hard soil piling construction; The 2nd, the spring load area increases, and stress point increases, and has increased resistance to overturning; The 3rd, number of springs increases, and the power that impulses is better cushioned, and kinetic energy more effectively is converted into elastic potential energy, carries out vibropiling, has reduced energy loss, reaches energy-saving effect.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a vertical view of the present utility model
Further describe embodiment below more in conjunction with the accompanying drawings: the left and right sides of pile monkey casing (5) is fixed with left spring seat (8) and right spring base (6 '), and top rail (1) is positioned at top.Spring (2) divides the secondary installing; The higher level is under the top rail (1) and between left spring seat (6) and the right spring base (8 '), bilateral symmetry is respectively established 3, totally 6 springs; Subordinate also respectively establishes 3 for bilateral symmetry under left spring seat (6) and right spring base (6 '), totally 6 springs (2).Secondary totally 12 springs (2) up and down.Two heads of the head portion of higher level's spring (2), subordinate's spring (2) are provided with spring conductor rod (3) and spring fastening (4).

Claims (1)

1, a kind of vibropiling hammer damping device, between the left spring seat (8) and right spring base (8 ') of top rail (1) and pile monkey casing (5), reach and below spring base (8) (8 '), all be provided with the spring (2) that has guiding and stand apparatus, it is characterized in that described spring (2) has 12, divide two layers and be installed in left spring seat (8) and right spring base (8 ') top and bottom, 6 of one decks, and bilateral symmetry.
